The hollow fiber membrane module 1 is used for, for example, activated sludge treatment, and a plurality of hollow fiber membrane modules 1 are provided in a filtration apparatus. In a filtration apparatus provided with a plurality of hollow fiber membrane modules 1, for example, plate-like hollow fiber membrane modules 1 are accommodated in a treatment tank (which may be open or closed) in a row, a liquid to be treated is introduced into the treatment tank, and the introduced liquid passes through the hollow fiber membrane modules 1, whereby the liquid is filtered. The hollow fiber membrane module 1 is not limited to use in an activated sludge treatment apparatus, and may be used in a large-scale wastewater treatment apparatus or a water purification treatment apparatus, for example.
As shown in fig. 1 and 2, the hollow fiber membrane module 1 has a plate-like shape as a whole, and in a state of use in which it is attached to a filtration apparatus, the extending direction of the hollow fiber membranes 21 is arranged along the vertical direction. Hereinafter, the vertical direction is sometimes referred to as the Z direction, two directions orthogonal to each other in the horizontal plane are sometimes referred to as the X direction and the Y direction, and the upper side (the side above the paper surface in fig. 1) and the lower side (the side below the paper surface in fig. 1) in the Z direction are sometimes simply referred to as the "upper side" and the "lower side". The positional relationship among the respective parts will be described with reference to the X direction, the Y direction, and the Z direction with respect to the hollow fiber membrane module 1 in the usage state. The posture when the hollow fiber membrane module 1 is used may be other than the posture along the vertical direction.
In the processing section 2, a plurality of hollow fiber membranes 21 extending linearly with the Z direction as the extending direction are arranged in the X direction. Thereby, the treatment unit 2 is formed in a sheet shape (flat plate shape) extending along the ZX plane. That is, the Y direction is the thickness direction of the processing unit 2. The hollow fiber membrane 21 is a hollow fiber membrane similar to a known hollow fiber membrane, and is formed in a cylindrical shape (tubular shape), and the ends 21A and 21B on both sides are open, and the liquid is introduced into the hollow fiber membrane 21 through the hollow fiber membrane 21, whereby the liquid is filtered.
More specifically, the treatment section 2 is formed by arranging a plurality of hollow fiber membrane bundles 4 in parallel. As shown in fig. 6, the hollow fiber membrane bundle 4 is formed by bundling a plurality of hollow fiber membranes 21. The hollow fiber membrane bundle 4 has a pair of sealing frames 22, and the pair of sealing frames 22 tightly bind and hold the plurality of hollow fiber membranes 21 to each other. Specifically, the sealing frame 22 is a quadrangular cylindrical member, and holds the end portions 21A and 21B of the bundled plurality of hollow fiber membranes 21. The sealing frame 22 and the end portions 21A and 21B of the hollow fiber membranes 21 are sealed by a sealing portion 23 made of polyurethane or the like. Specifically, sealing portion 23 is in liquid-tight contact with the outer peripheral surfaces of end portions 21A, 21B of hollow fiber membranes 10, and with the inner peripheral surface of sealing frame 22, thereby sealing the space between sealing frame 22 and hollow fiber membranes 21. The openings of the end portions 21A, 21B of the hollow fiber membranes 21 are not sealed, and the hollow fiber membranes 21 communicate with the outside via the openings.
As shown in fig. 1 and 2, the support body 3 is formed in a rectangular frame shape so as to surround the processing unit 2. In the support body 3, the holding portions 41 and 42 extend in the X direction, and the support portions 51 and 52 extend in the Z direction. The dimension in the X direction in the frame of the support 3 is set to be equal to or slightly larger than the dimension in the X direction of the processing unit 2, for example, and the dimension in the Z direction in the frame of the support 3 is set to be equal to or slightly smaller than the dimension in the Z direction of the processing unit 2, for example. That is, the hollow fiber membranes 21 may be loosely stretched between the holding portions 41 and 42.
As shown in fig. 3 and 4, the holding portions 41 and 42 have grooves 47 that open in one direction orthogonal to the extending direction. The groove 47 extends in the extending direction of the holding portions 41, 42. As shown in fig. 3 and 4, the groove 47 forms a groove upper portion 47A and a groove lower portion 47B as two spaces. In the groove 47, a groove upper portion 47A and a groove lower portion 47B overlap each other. Specifically, the groove upper portion 47A is a space having an opening of the groove 47 and communicates with the groove lower portion 47B, and the groove lower portion 47B is a space closed by the holding portions 41 and 42 except for a portion connected to the groove upper portion 47A, and forms a flow path as described later. One sealing frame 22 of the hollow fiber membrane bundle 4 is accommodated in the groove upper portion 47A of the groove 47 of the upper holding portion 41, and the other sealing frame 22 of the hollow fiber membrane bundle 4 is accommodated in the groove upper portion 47A of the groove 47 of the lower holding portion 42. The plurality of seal frames 22 are accommodated in a row in the groove upper portion 47A of the holding portion 41, and the plurality of seal frames 22 are accommodated in a row in the groove upper portion 47A of the holding portion 42. The plurality of seal frames 22 accommodated in the groove upper portions 47A of the holding portions 41, 42 are fixed to the holding portions 41, 42 by an adhesive. With this adhesive material, the sealing of the groove lower portion 47B with respect to the outside of the groove 47 is achieved. Thus, the groove lower portions 47B of the grooves 47 of the holding portions 41, 42 communicate with the openings of the hollow fiber membranes 21 of the hollow fiber membrane bundles 4, and the groove lower portions 47B serve as flow paths through which the liquid filtered by the hollow fiber membranes 21 can pass.
The suction pump can be connected to the ends 411 and 412 of the upper holding portion 41 on both sides in the X direction by forming the connection port 410. Openings similar to the connection port 410 are formed in the end portions 421 and 422 of the lower holding portion 42 on both sides in the X direction, and the openings are closed by providing plugs 9 (see fig. 3 and 9). The connection opening 410 may not be formed in the lower holding portion 42. As shown in the figure, the end portions 411 and 412 of the upper holding portion 41 may not block the groove lower portion 47B of the groove 47 in the extending direction (X direction) by the wall portion 44A, or the connection port 410 may be formed by not forming the wall portion 44A in the groove lower portion 47B. Similarly, the end portions 421 and 422 of the lower holding portion 42 may not block the groove lower portion 47B of the groove 47 in the extending direction (X direction) by the wall portion 44A as shown in the drawing, or may form an opening similar to the connection port 410 by not forming the wall portion 44A in the groove lower portion 47B. In this case, the plug 9 has a shape following the cross-sectional shape of the groove bottom portion 47B, and closes the opening. In the holding portion 41, the end portion 412 side is formed in the same manner as the end portion 411 side, and in the holding portion 42, the end portion 422 side is formed in the same manner as the end portion 421 side.
The column parts 51 and 52 are formed in a tubular shape having an internal space through which liquid can pass. The column portion 51 disposed on one side in the X direction connects the end 411 of the upper holding portion 41 and the end 421 of the lower holding portion 42. The support portion 52 disposed on the other side in the X direction connects the end portion 412 of the upper holding portion 41 and the end portion 422 of the lower holding portion 42. Thus, the groove lower portions 47B of the holding portions 41 and 42 and the internal spaces of the column portions 51 and 52 can selectively communicate with each other through the connecting portion 30 as described later. In the present embodiment, as will be described later using fig. 3 and 8, a connection portion 30 capable of connecting the groove lower portion 47B of the holding portion 42 and the internal space of the column portion 51 is provided at the end portion 421 of the lower holding portion 42, and a connection portion 30 capable of connecting the groove lower portion 47B of the holding portion 41 and the internal space of the column portion 52 is provided at the end portion 412 of the upper holding portion 41. On the other hand, as will be described later with reference to fig. 7 and 9, a connection portion 30 is provided at an end 411 of the upper holding portion 41, a partition wall 48 for partitioning the portion of the groove lower portion 47B of the holding portion 41 communicating with the hollow fiber membrane module 21 from the internal space of the column portion 51 is formed at the connection portion 30, a connection portion 30 is provided at an end 422 of the lower holding portion 42, and a partition wall 48 for partitioning the portion of the groove lower portion 47B of the holding portion 42 communicating with the hollow fiber membrane module 21 from the internal space of the column portion 52 is formed at the connection portion 30. Thus, the support body 3 is formed with a bottom-up L-shaped flow path formed by the lower holding portion 42 and the pillar portion 51, and a flow path along the upper holding portion 41. Thus, two independent flow paths are formed in the support body 3.
The support body 3 is configured as described above, and two independent L-shaped flow paths and straight flow paths are formed, and a suction pump is connected to the connection port 410 on the end 412 side in the upper holding portion 41, and the inside of the groove lower portion 47B is sucked and depressurized, whereby a part of the liquid guided into the hollow fiber membrane 21 and filtered enters the groove lower portion 47B of the upper holding portion 41 through the hollow fiber membrane 21, flows toward the end 412 side in the groove lower portion 47B of the holding portion 41, and is discharged from the connection port 410. Further, a suction pump is connected to the connection port 410 on the end 411 side in the upper holding portion 41, and the inside of the groove lower portion 47B is sucked and depressurized, whereby another part of the liquid guided into the hollow fiber membrane 21 and filtered enters the groove lower portion 47B of the lower holding portion 42 through the hollow fiber membrane 21, flows toward the end 421 side in the groove lower portion 47B of the holding portion 42, passes through the support column portion 51 on the X direction side toward the upper side, reaches the upper holding portion 41, and is discharged from the connection port 410 on the end 411 side.
In the present embodiment, the holding portion 41 and the holding portion 42 have the same configuration, and the column portion 51 and the column portion 52 have the same configuration. In the support body 3, the holding portions 41 and 42 are provided rotationally symmetrically with respect to an axis parallel to the Y direction. For example, the holding portion 41 and the holding portion 42 are common members common to each other. The holding portion 41 and the holding portion 42 may not be a common member shared by them. The manner of communication between the holding portions 41 and 42 and the support portions 51 and 52 in the support body 3, or the manner of discharge of the liquid filtered by the hollow fiber membranes 21 is not limited to the above-described configuration, and any configuration may be used as long as the liquid is filtered by the hollow fiber membranes 21 by suction using a suction pump and discharged from the support body 3.
Here, the connection structure between the holding portions 41 and 42 and the support portions 51 and 52 in the support body 3 will be described in detail with reference to fig. 3, 4, and 7 to 9. As shown in fig. 3, an end 421 of the lower holding portion 42 on one side in the X direction and an end 512 of the pillar portion 51 on the lower side are connected by the connection portion 31. As shown in fig. 7, an end 411 on one side in the X direction of the upper holding portion 41 and an upper end 511 of the pillar portion 51 are connected by a connecting portion 32. As shown in fig. 8, the other end 412 of the upper holding portion 41 in the X direction and the upper end 521 of the support portion 52 are connected by a connection portion 33, and as shown in fig. 9, the other end 422 of the lower holding portion 42 in the X direction and the lower end 522 of the support portion 52 are connected by a connection portion 34.
As shown in fig. 3 and 4, the connection portion 31 at the end 421 of the holding portion 42 includes: an arrangement portion 43, wherein an end portion 512 of the pillar portion 51 is arranged in the arrangement portion 43; and wall portions 44A to 44D that face the pillar portion 51 disposed in the arrangement portion 43 to form a space ( insertion portions 46A and 46B) adjacent to the pillar portion 51, and the reinforcing members 6 and 7 are formed to be inserted into the insertion portions 46A and 46B forming the space and attached thereto. Specifically, the connecting portion 31 is formed with an arrangement portion 43 protruding toward the upper side in the Z direction, a pair of wall portions 44A, 44B facing each other in the X direction across the arrangement portion 43, and a pair of wall portions 44C, 44D facing each other in the Y direction across the arrangement portion 43. A predetermined distance is provided between each of the pair of wall portions 44A, 44B and the arrangement portion 43, and the distance in the X direction between the wall portion 44A on one side (outer side) in the X direction and the arrangement portion 43 is larger than the distance in the X direction between the wall portion 44B on the other side (inner side) in the X direction and the arrangement portion 43. The arrangement portion 43 and the pair of wall portions 44A, 44B protrude from the common bottom portion 45, the pair of wall portions 44A, 44B are formed higher than the arrangement portion 43 and have a larger protruding dimension, and the wall portion 44A is formed higher than the wall portion 44B. The wall portions 44C and 44D are portions of a pair of side surfaces extending in the longitudinal direction of the holding portion 42. The bottom portion 45 is a plate-like portion provided on the bottom wall 42A of the holding portion 42 so as to face each other with a gap. The bottom wall 42A is a portion forming the bottom of the groove 47 in the holding portion 42. The bottom portion 45 may be provided at a joint portion between the groove upper portion 47A and the groove lower portion 47B in the groove 47, or may be provided at a position above or below the joint portion.
The arrangement portion 43 has a shape that can be inserted or press-fitted into the opening 512A of the end portion 512 of the column portion 51. The arrangement portion 43 has a shape corresponding to the opening 512A of the pillar portion 51, and has, for example, a quadrangular tube shape. In a state where the placement portion 43 is inserted into the opening 512A, an insertion portion 46A is formed by the pillar portion 51, the wall portion 44A, the wall portion 44C, the wall portion 44D, and the bottom portion 45, the insertion portion 46A being a space opened to the upper side in the Z direction, and similarly, an insertion portion 46B is formed by the pillar portion 51, the wall portion 44B, the wall portion 44C, the wall portion 44D, and the bottom portion 45, the insertion portion 46B being a space opened to the upper side in the Z direction. Further, a gap may be formed between the pillar portion 51 and the pair of wall portions 44C and 44D, or no gap may be formed. As described above, the X-direction dimension of the outer insertion portion 46A is larger than the X-direction dimension of the inner insertion portion 46B, and the Y-direction dimensions thereof are the same or substantially the same. Thus, the insertion portion 46A and the insertion portion 46B have different sizes from each other. Therefore, it is possible to prevent the corresponding reinforcing members 6, 7 described later from being erroneously mounted.
The reinforcing members 6, 7 are respectively formed to be inserted and attached to the insertion portions 46A, 46B, the reinforcing member 6 is provided at the insertion portion 46A, and the reinforcing member 7 is provided at the insertion portion 46B. For example, the X-direction dimension of the reinforcing member 6 is larger than the X-direction dimension of the reinforcing member 7 due to the difference in the X-direction dimensions of the insertion portions 46A, 46B, and the Y-direction dimension and the Z-direction dimension thereof are the same or substantially the same. The reinforcing members 6 and 7 have the same shape, and the shape of the reinforcing member 6 will be described below, but unless otherwise specified, the reinforcing member 7 also has the same shape corresponding to the insertion portion 46B.
The reinforcing member 6 has a shape corresponding to the shape of the insertion portion 46A, and is attached to the insertion portion 46A in a state of being fitted with a gap or an intermediate fit. The reinforcing member 6 may be fitted to the insertion portion 46A in an interference fit manner. The reinforcing member 6 has, for example, a quadrangular tube shape, and as shown in fig. 5, the reinforcing member 6 has a hollow portion 61 forming a space extending along the Z direction in which the reinforcing member 6 is inserted into the insertion portion 46A, and a quadrangular tube-shaped outer tube portion 62 partitioning the hollow portion 61. The reinforcing member 6 has a plate-like partition portion 64 that divides the hollow portion 61 into two spaces. The dividing portion 64 extends, for example, in the insertion direction of the reinforcing member 6 and extends along the ZX plane. The hollow portion 61 is formed in a through hole shape having both ends opened in the Z direction. The outer tube portion 62 includes a plate portion 62A facing the wall portion 44A, a plate portion 62B facing the pillar portion 51, a plate portion 62C facing the wall portion 44C, and a plate portion 62D facing the wall portion 44D in a state where the reinforcing member 6 is attached to the insertion portion 46A.
Two projecting portions 63 are provided on the outward surfaces 620A to 620D of the plate portions 62A to 62D, respectively, and the projecting portions 63 project toward the side opposite to the hollow portion 61. Protrusion 63 formed on surface 620A protrudes toward wall 44A, and is formed to face wall 44A with a gap therebetween or to contact wall 44A. The protrusion 63 formed on the surface 620B protrudes toward the column part 51, and is formed to face the column part 51 with a gap therebetween or to contact the column part 51. Protrusions 63 formed on surfaces 620C and 620D protrude toward wall portions 44C and 44D, respectively, and are formed so as to face wall portions 44C and 44D with a gap therebetween or so as to contact wall portions 44C and 44D. In the plate portion 62A and the plate portion 62B, the protruding portions 63 are formed symmetrically in the Y direction, and in the plate portion 62C and the plate portion 62D, the protruding portions 63 are formed symmetrically in the X direction.
The dimension in the X direction of the reinforcing member 6 including the protrusion 63 is the same as or substantially the same as the dimension in the X direction of the insertion portion 46A (the interval between the wall portion 44A and the pillar portion 51). The dimension in the Y direction of the reinforcing member 6 including the protruding portion 63 is the same as or substantially the same as the dimension in the Y direction of the insertion portion 46A (the interval between the wall portion 44C and the wall portion 44D). Thereby, the reinforcing member 6 is fitted into the insertion portion 46A as described above. The reinforcing member 6 moves in the Z direction in the insertion portion 46A until it comes into contact with the bottom portion 45, and is fitted into the insertion portion 46A. The dimension in the X direction and the dimension in the Y direction of the reinforcing member 6 including the protrusion 63 are preferably smaller by about 0.1 to 3mm, and more preferably smaller by about 0.5 to 2mm, respectively, than the dimension in the X direction and the dimension in the Y direction of the insertion portion 46A. By setting the X-direction dimension and the Y-direction dimension of the reinforcing member 6 to be smaller than the corresponding dimensions of the insertion portion 46A in this way, workability in inserting the reinforcing member 6 into the insertion portion 46A can be improved.
The reinforcing member 7 also has a hollow portion 71, an outer tube portion 72, a projecting portion 73, and a dividing portion 74 corresponding to the hollow portion 61, the outer tube portion 62, the projecting portion 63, and the dividing portion 64, respectively, similarly to the reinforcing member 6, and the reinforcing member 7 is attached to the insertion portion 46B in a clearance fit or an intermediate fit state. The reinforcing member 7 may be fitted to the insertion portion 46B in an interference fit manner. The outer tube portion 72 is formed by plate portions 72A to 72D corresponding to the plate portions 62A to 62D, respectively, and the protruding portions 73 protrude from surfaces 720A to 720D of the outer tube portion 72 corresponding to the surfaces 620A to 620D of the outer tube portion 62, respectively. The protrusion 73 of the reinforcing member 7 is formed to face the wall 44B, the pillar 51, the wall 44C, or the wall 44D with a gap therebetween or to contact therewith. The reinforcing member 7 moves along the insertion portion 46B in the Z direction until it comes into contact with the bottom portion 45, and is fitted into the insertion portion 46B. The dimension in the X direction and the dimension in the Y direction of the reinforcing member 7 including the protruding portion 73 are preferably smaller by about 0.1 to 3mm, more preferably about 0.5 to 2mm, respectively, with respect to the dimension in the X direction and the dimension in the Y direction of the insertion portion 46B. This can improve workability in inserting the reinforcing member 7 into the insertion portion 46B.
As described above, in the state where the reinforcing members 6, 7 are fitted into the insertion portions 46A, 46B, the filler 8 is provided inside the hollow portions 61, 71, between the plate portions 62B, 72B and the column portions 51, 52, between the plate portions 62A, 72A and the wall portions 44A, 44B, and between the plate portions 62C, 62D, 72C, 72D and the wall portions 44C, 44D. The filler 8 is an adhesive material made of, for example, a urethane adhesive, and includes a first adhesive material 81, a second adhesive material 82, and a third adhesive material 83. The first adhesive member 81 is provided on the bottom portion 45 side, the second adhesive member 82 is laminated on the treatment portion 2 side of the first adhesive member 81, and the third adhesive member 83 is laminated on the treatment portion 2 side of the second adhesive member 82. As shown in fig. 3 and 7 to 9, the second adhesive 82 serves as the sealing portion 23 of the hollow fiber membrane bundle 4, and the third adhesive 83 is attached to the root portion of the hollow fiber membrane 21 at the sealing portion 23 for filling the groove upper portion 47A of the groove 47. The third adhesive 83 is attached to protect the hollow fiber membranes 21 and is attached to prevent the root portions of the hollow fiber membranes 21 from being broken or damaged by vibration.
The first adhesive material 81 is more easily elastically deformed than the second adhesive material 82, and the second adhesive material 82 is harder than the first adhesive material 81. Therefore, as described later, when the support body 3 is deformed, the deformation of each portion is easily allowed by the first adhesive material 81, and the deformation of each portion is suppressed by the second adhesive material 82. This makes it easy to suppress damage to the proximal end portion 43A of the arrangement portion 43 and the end portion 512 of the column portion 51. In addition, the third adhesive 83 is easily elastically deformed similarly to the first adhesive 81, and the third adhesive 83 flexibly holds the root portion of the hollow fiber membrane 21 and the sealing portion 23. In the present embodiment, the first adhesive 81 and the third adhesive 83 are the same adhesive, but may be different adhesives.
By forming the protrusions 63, 73 in the reinforcing members 6, 7, gaps are formed between the surfaces 620A to 620D and the wall portion 44A, the pillar portion 51, the wall portion 44C, and the wall portion 44D that face each other, and gaps are formed between the surfaces 720A to 720D and the wall portion 44B, the pillar portion 51, the wall portion 44C, and the wall portion 44D that face each other. Specifically, a gap is inevitably formed between the portion of the surface 620B other than the projection 63 and the pillar 51, a gap is inevitably formed between the portion of the surface 620A other than the projection 63 and the wall 44A, a gap is inevitably formed between the portion of the surface 620C other than the projection 63 and the wall 44C, and a gap is inevitably formed between the portion of the surface 620D other than the projection 63 and the wall 44D. Further, a gap is inevitably formed between the portion of the surface 720B other than the projection portion 73 and the pillar portion 51, a gap is inevitably formed between the portion of the surface 720A other than the projection portion 73 and the wall portion 44B, a gap is inevitably formed between the portion of the surface 720C other than the projection portion 73 and the wall portion 44C, and a gap is inevitably formed between the portion of the surface 720D other than the projection portion 73 and the wall portion 44D. By forming the gaps around the reinforcing members 6 and 7 in this way, it is easier to fill the filler 8 around the reinforcing members 6 and 7 inserted into the insertion portions 46A and 46B, respectively, than in the case where no gaps are formed. Two projections 63 and 73 are provided on each surface of the reinforcing members 6 and 7. Therefore, the two protrusions 63 and 73 are interposed between the respective surfaces of the reinforcing members 6 and 7 and the respective surfaces of the reinforcing members 6 and 7 on the side of the holding members 41 and 42, respectively, and therefore the gap between the reinforcing members 6 and 7 can be maintained at a constant interval or more.
When a force in the X direction, for example, acts on the hollow fiber membrane module 1, the rectangular frame-shaped support body 3 is also deformed into a parallelogram. That is, the support portions 51 and 52 are swung with respect to the holding portions 41 and 42. In such a rocking motion, the arrangement portion 43 is easily deformed, and the load is easily concentrated on the base end portion 43A of the arrangement portion 43.
By providing the reinforcing members 6 and 7 in the hollow fiber membrane module 1, the oscillation of the support column sections 51 and 52 with respect to the holding sections 41 and 42 can be suppressed. Further, since the insertion portions 46A and 46B are formed in the connecting portion 30 as spaces in which the reinforcing members 6 and 7 are provided, when the column portions 51 and 52 are assembled to the holding portions 41 and 42, respectively, a gap can be secured between the column portions 51 and 52 and the wall portions 44A and 44B, and the assembling property can be improved.
Further, by forming the protrusions 63 and 73 in the reinforcing members 6 and 7, the filler 8 can be easily filled as described above, and the adhesiveness between the reinforcing members 6 and 7 and the column parts 51 and 52 and the wall parts 44A, 44B, 44C, and 44D can be improved. This can prevent the column parts 51 and 52 from easily wobbling due to the separation of the filler 8. That is, deformation of the support body 3 can be suppressed, the arrangement portion 43 and the like are not easily damaged, and the durability of the hollow fiber membrane module 1 can be improved.
Further, since the reinforcing members 6, 7 have the dividing portions 64, 74 extending along the ZX plane and dividing the hollow portions 61, 71, respectively, even if an external force is applied to the reinforcing members 6, 7 due to the swinging of the column portions 51, 52, deformation such as crushing of the hollow portions 61, 71 is less likely to occur, and the rigidity of the reinforcing members 6, 7 can be improved, whereby the swinging of the column portions 51, 52 can be suppressed.
As described above, according to the hollow fiber membrane module 1 of the embodiment of the present invention, the reinforcing members 6 and 7 are provided in the connection portion 30, and the protrusions 63 and 73 are formed in the reinforcing members 6 and 7, whereby the durability can be improved.
Further, since the reinforcing members 6 and 7 have the dividing portions 64 and 74, the strength of the reinforcing members 6 and 7 is improved, and the durability of the hollow fiber membrane module 1 can be further improved.
As shown in fig. 7 to 9, the connection portions 32, 33, and 34 have the same configuration as the connection portion 31, but the connection portion 31 is different from the connection portion 32, and the connection portion 33 is different from the connection portion 34 in the configuration in which the flow path between the holding portion 41 and the support portions 51 and 52 is formed, or the configuration in which the flow path between the holding portion 42 and the support portions 51 and 52 is formed. In the connection portion 31 shown in fig. 3 and 4, the portion of the groove lower portion 47B adjacent to the bottom portion 45 and the portion of the groove lower portion 47B adjacent to the bottom portion 45 communicate with each other. The disposition portion 43 has a hollow portion 43C penetrating the base end portion 43A and the tip end portion 43B, and the hollow portion 43C of the disposition portion 43 penetrates the bottom portion 45 and communicates with the groove lower portion 47B as a flow path from the hollow fiber membrane 21.
On the other hand, as shown in fig. 7, the connecting portion 32 provided at the end 411 of the holding portion 41 connected to the suction pump is provided with a partition wall 48, and the partition wall 48 is a plate-shaped portion that partitions a portion of the groove lower portion 47B adjacent to the bottom portion 45 and a portion of the groove lower portion 47B adjacent to the bottom portion 45. Thus, the liquid filtered by the hollow fiber membranes 21 and rising in the column part 51 is directed toward the connection port 410 without flowing to the groove lower part 47B of the holding part 41 communicating with the hollow fiber membranes 21. The partition wall 48 may not be provided in the connection portion 32.
As shown in fig. 8, the connection portion 33 provided at the other end portion 412 of the holding portion 41 connected to the suction pump has the same configuration as the connection portion 31 provided at the end portion 421 of the holding portion 42. Specifically, the portion of the groove lower portion 47B adjacent to the bottom portion 45 communicates with the portion of the groove lower portion 47B adjacent to the bottom portion 45, and the hollow portion 43C of the arrangement portion 43 penetrates the bottom portion 45 and communicates with the groove lower portion 47B of the holding portion 41 serving as a flow path from the hollow fiber membrane 21. Thus, in the end portion 412 of the holding portion 41, the liquid filtered by the hollow fiber membranes 21 and rising through the hollow fiber membranes 21 flows from the end portion 411 side to the end portion 412 side in the groove lower portion 47B of the holding portion 41, and is directed toward the connection port 410. For example, the connection portion 31 and the connection portion 33 are common members that are common to each other, and change the mounting position, mounting direction to function as the connection portion 31 or the connection portion 33. The connection portion 31 and the connection portion 33 may not be common members.
As shown in fig. 9, the connection portion 34 provided at the end 422 of the lower holding portion 42 has the same configuration as the connection portion 32 provided at the end 411 of the holding portion 41. Specifically, a partition wall 48 is provided, and the partition wall 48 is a plate-shaped portion that partitions a portion of the groove lower portion 47B adjacent to the bottom portion 45 and a portion of the groove lower portion 47B adjacent to the bottom portion 45. Further, the connection port 410 of the end 422 of the holding portion 42 is closed by the plug 9. This prevents the liquid filtered by hollow fiber membranes 21 and descending through hollow fiber membranes 21 from flowing through groove lower 47B of holding part 42 communicating with hollow fiber membranes 21 and flowing out from connection port 410 on the side of end 422 of holding part 42, and prevents the liquid descending through support column part 52 from flowing out from connection port 410 on the side of end 422 of holding part 42 without flowing through groove lower 47B of holding part 42 communicating with hollow fiber membranes 21. For example, the connection portion 32 and the connection portion 34 are common members that are common to each other, and the common members change the mounting position, mounting direction to function as the connection portion 32 or the connection portion 34. The connection portion 32 and the connection portion 34 may not be common components. The partition wall 48 may not be provided in the connection portion 34.
The present invention is not limited to the above-described embodiments, and includes other configurations and the like that can achieve the object of the present invention, and modifications and the like shown below are also included in the present invention. For example, in the first embodiment of the present invention described above, the reinforcing members 6 and 7 have the wall- like dividing portions 64 and 74 along the insertion direction, but the dividing portions that divide the hollow portion may have other shapes as long as they generate a force against the swinging of the column portions 51 and 52. For example, the dividing portion may have a dimension in the Z direction smaller than the dimension in the Z direction of the entire reinforcing member, or the dividing portion may be formed in a rod shape extending in the X direction. The dividing portion may extend in a direction inclined to the insertion direction, or may extend in a direction orthogonal to the insertion direction. The reinforcing members 6 and 7 may have a plurality of divided portions. Further, for example, in the case where the reinforcing member is difficult to deform sufficiently, such as the case where the thickness of the outer tube portion is sufficiently large, the case where the strength of the material of the reinforcing member is high, and the case where the size of the reinforcing member is small, the partitioning portion may not be formed.
As a modification, as shown in fig. 10, instead of forming the dividing portions, a plurality of reinforcing members may be inserted into the insertion portions 46A and 46B. For example, a plurality of reinforcing members 10 may be arranged in the Y direction in the insertion portion 46A, or a plurality of reinforcing members 11 may be arranged in the Y direction in the insertion portion 46B. In the illustrated example, two reinforcing members 10 are provided in the insertion portion 46A in the Y direction, and a plurality of reinforcing members 11 are provided in the insertion portion 46B in the Y direction. The reinforcing members 10 and 11 have hollow portions 101 and 111 and outer tube portions 102 and 112, as with the reinforcing members 6 and 7, and the outer tube portions 102 and 112 have protrusions 103 and 113 formed thereon, and no dividing portions formed thereon. The protrusions 103, 103 are not formed on the surfaces of the reinforcing members 10, 11 facing the other reinforcing members 10, 11. By arranging a plurality of separate reinforcing members 10, 11 in the Y direction in this manner, the Y direction dimension of the entire one reinforcing member 10, 11 and the Y direction dimension of the hollow portion 101, 111 can be reduced as compared with a structure in which only one reinforcing member is provided, and the rigidity of the reinforcing members 10, 11 can be improved. Thus, the durability of the hollow fiber membrane module can be improved in the same manner as the structure forming the partition portion.
In addition, a plurality of the reinforcing members having the partitioning portions as in the first embodiment of the present invention may be arranged in the Y direction, and according to this structure, the durability of the hollow fiber membrane module can be further improved.
In the first embodiment of the present invention described above, the insertion portion 46A and the insertion portion 46B sandwich the column portions 51 and 52 in the X direction, respectively, but the insertion portion 46A and the insertion portion 46B may sandwich the column portions 51 and 52 in the Y direction, respectively.
In the first embodiment of the present invention described above, the reinforcing members 6 and 7 have a cylindrical shape having the hollow portions 61 and 71, but the shape of the reinforcing member of the present invention is not limited to a cylindrical shape. The reinforcing member may be formed in a bottomed cylindrical shape (cup shape) having an opening on one side (upper side or lower side) in the insertion direction, or may be formed in a block shape having no opening. In addition, a hollow portion having a concave shape (non-penetrating shape) may be formed in the bottomed cylindrical reinforcing member, and a partitioning portion for partitioning the hollow portion may be provided. Further, the hollow portion or the concave portion of the reinforcing member may be filled with a filler.
In the first embodiment of the present invention described above, the placement portion 43 protrudes in a cylindrical shape and is inserted into the pillar portions 51 and 52, but the placement portion may have a shape that allows the pillar portions to be placed. For example, a groove or a recess may be formed in the bottom portion 45 and the pillar portion may be inserted, and the groove or the recess may be used as the arrangement portion. That is, the placement portion may be any portion as long as it can position the column portion. Further, the support column portion may not be provided.

In the reinforcing member 6, the protrusion 63 may extend obliquely in the insertion direction (Z direction), or may extend in a curved manner instead of extending linearly. The protrusion 63 may extend in a direction orthogonal to the insertion direction. The same applies to the reinforcing members 7, 10, and 11.
In addition, only one of the insertion portions 46A and 46B may be provided in all the connection portions 30 or in any one of the connection portions 30. For example, either one of the wall portion 44B and the wall portion 44A may be brought into contact with or opposed to the support portions 51 and 52 connected to the connection portion 30 with a gap therebetween, and only either one of the insertion portion 46A and the insertion portion 46B may be formed in the connection portion 30.
In the first embodiment of the present invention described above, the reinforcing members 6, 7 or the reinforcing members 10, 11 are provided in all the connecting portions 30, but the reinforcing members 6, 7 or the reinforcing members 10, 11 may not be provided in the connecting portions 30 where the generated load is small. Further, the connecting portions may be selectively provided in the respective connecting portions from among the connecting portion 30 provided with the reinforcing members 6, 7 or the reinforcing members 10, 11, the connecting portion 30 provided with only one of the insertion portion 46A and the insertion portion 46B, and the connecting portion 30 not provided with the reinforcing members 6, 7 or the reinforcing members 10, 11. Similarly, a reinforcing member may be selectively provided in each connecting portion 30 from among the reinforcing members 6 and 7 or the reinforcing members 10 and 11. Further, the connection portions may be selectively provided from the connection portions 31, 32, 33, and 34 in the respective connection portions.
Hereinafter, a second embodiment of the present invention will be described with reference to the drawings. The same reference numerals are used for members having the same functions as or the same as those of the hollow fiber membrane module 1 according to the first embodiment of the present invention, and the description thereof will be omitted.

An opening portion 49 for projecting the regulating portion 275 of the reinforcing member 7 inserted into the insertion portion 46B to the outside of the insertion portion 46B is formed in a part of the plurality of insertion portions 46A, 46B (insertion portion 46B), and is different in size from the other plurality of insertion portions 46A. Hereinafter, the hollow fiber membrane module 1 will be specifically described.
The connection structure between the holding portions 41 and 42 and the support portions 51 and 52 in the support body 3 will be described in detail with reference to fig. 12, 13, and 20 to 22. As shown in fig. 12, an end 421 of the lower holding portion 42 on one side in the X direction and an end 512 of the pillar portion 51 on the lower side are connected by the connection portion 31. As shown in fig. 20, an end 411 on one side in the X direction of the upper holding portion 41 and an upper end 511 of the pillar portion 51 are connected by a connecting portion 32. As shown in fig. 21, the other end 412 of the upper holding portion 41 in the X direction and the upper end 521 of the support portion 52 are connected by a connection portion 33, and as shown in fig. 22, the other end 422 of the lower holding portion 42 in the X direction and the lower end 522 of the support portion 52 are connected by a connection portion 34.
As shown in fig. 12 and 13, the connecting portion 31 at the end 421 of the holding portion 42 includes: an arrangement portion 43, wherein an end portion 512 of the pillar portion 51 is arranged in the arrangement portion 43; and wall portions 44A to 44D that face the pillar portion 51 disposed in the arrangement portion 43 to form a space ( insertion portions 46A and 46B) adjacent to the pillar portion 51, and the reinforcing members 206 and 207 are formed to be inserted into and attached to the insertion portions 46A and 46B forming the space. Specifically, the connecting portion 31 is formed with an arrangement portion 43 protruding toward the upper side in the Z direction, a pair of wall portions 44A, 44B facing each other in the X direction across the arrangement portion 43, and a pair of wall portions 44C, 44D facing each other in the Y direction across the arrangement portion 43. A predetermined distance is provided between each of the pair of wall portions 44A, 44B and the arrangement portion 43, and the distance in the X direction between the wall portion 44A on one side (outer side) in the X direction and the arrangement portion 43 is larger than the distance in the X direction between the wall portion 44B on the other side (inner side) in the X direction and the arrangement portion 43. The arrangement portion 43 and the pair of wall portions 44A, 44B protrude from the common bottom portion 45, the pair of wall portions 44A, 44B are formed to be higher than the arrangement portion 43 and have a larger protruding dimension, and the wall portion 44A is formed to be higher than the wall portion 44B. The wall portions 44C and 44D are portions of a pair of side surfaces extending in the longitudinal direction of the holding portion 42. The bottom portion 45 is a plate-like portion provided to face the bottom wall 42A of the holding portion 42 with a space. The bottom wall 42A is a portion forming the bottom of the groove 47 in the holding portion 42. The bottom portion 45 may be provided at a joint portion between the upper portion 47A and the lower portion 47B of the groove 47, or may be provided at a position above or below the joint portion.
The arrangement portion 43 has a shape that can be inserted or press-fitted into the opening 512A of the end portion 512 of the column portion 51. The arrangement portion 43 has a shape corresponding to the opening 512A of the column portion 51, and has, for example, a rectangular tubular shape. In a state where the placement portion 43 is inserted into the opening 512A, an insertion portion 46A is formed by the pillar portion 51, the wall portion 44A, the wall portion 44C, the wall portion 44D, and the bottom portion 45, the insertion portion 46A being a space opened to the upper side in the Z direction, and similarly, an insertion portion 46B is formed by the pillar portion 51, the wall portion 44B, the wall portion 44C, the wall portion 44D, and the bottom portion 45, the insertion portion 46B being a space opened to the upper side in the Z direction. Further, a gap may be formed between the pillar portion 51 and the pair of wall portions 44C and 44D, or no gap may be formed. As described above, the X-direction dimension of the outer insertion portion 46A is larger than the X-direction dimension of the inner insertion portion 46B, and the Y-direction dimensions thereof are the same or substantially the same. Thus, the insertion portion 46A and the insertion portion 46B have different sizes from each other.
As described above, in the hollow fiber membrane module 201 according to the second embodiment of the present invention, the two insertion portions 46A and 46B are provided in the connection portion 31. In the connecting portion 31, an insertion portion 46B having a small width in the extending direction is provided on the inner side (wall portion 44B side) in the extending direction (X direction) of the holding portion 42, and an insertion portion 46A having a large width in the extending direction is provided on the outer side (wall portion 44A side) in the extending direction (X direction) of the holding portion 42. As described later, the insertion portion 46B is formed with an open portion 49 that guides the regulating portion 275 of the reinforcing member 207.
The reinforcing members 206, 207 are formed to be inserted into and attached to the insertion portions 46A, 46B, respectively, the reinforcing member 206 is provided in the insertion portion 46A, and the reinforcing member 207 having the regulating portion 275 is provided in the insertion portion 46B. The reinforcing member 206 is formed in a shape to be fitted to the insertion portion 46A in a state of being fitted with a clearance or an intermediate fit. The reinforcing member 206 may be fitted to the insertion portion 46A in an interference fit manner. As also shown in fig. 14, the reinforcing member 206 has a hollow portion 261 forming a space extending along the Z direction, which is the direction in which the reinforcing member 206 is inserted into the insertion portion 46A, and has a quadrangular cylindrical outer cylindrical portion 262 dividing the hollow portion 261. The reinforcing member 206 has a plate-like partition 264 that divides the hollow 261 into two spaces. The dividing portion 264 extends, for example, in the insertion direction of the reinforcing member 206, and extends along the ZX plane. The hollow portion 261 is formed in a through hole shape having both ends opened in the Z direction. The outer tube 262 has plate portions 262A, 262B, 262C, 262D. In the state where the reinforcing member 206 is attached to the insertion portion 46A, the plate portion 262A faces the wall portion 44A, the plate portion 262B faces the pillar portion 51, the plate portion 62C faces the wall portion 44C, and the plate portion 62D faces the wall portion 44D.
Two projecting portions 263 are provided on the outward facing surfaces 2620A to 2620D of the plate portions 262A to 262D, respectively, and the projecting portions 263 are portions projecting toward the side opposite to the hollow portion 261 side. Projection 263 formed on surface 2620A projects toward wall 44A, and is formed to face wall 44A with a gap therebetween or to contact wall 44A. The protrusion 263 formed on the surface 2620B protrudes toward the post 51 and is formed to face the post 51 with a gap therebetween or to contact the post 51. The protrusions 263 formed on the surfaces 2620C, 2620D protrude toward the walls 44C, 44D, respectively, and are formed so as to face the walls 44C, 44D with a gap therebetween or so as to contact the walls 44C, 44D. The projecting portions 263 are formed symmetrically in the Y direction in the plate portions 262A and 262B, and the projecting portions 263 are formed symmetrically in the X direction in the plate portions 262C and 262D.
As shown in fig. 15, the reinforcing member 207 includes the restricting portion 275, and further includes a body portion 271, the body portion 271 being a portion forming an outer peripheral surface 271A, the outer peripheral surface 271A being a surface along a direction (Z direction) in which the reinforcing member 207 is inserted into the insertion portion 46B. The body 271 has a shape insertable into the insertion portion 46B, and is attached to the insertion portion 46B in a clearance fit or intermediate fit state. The body 271 may be fitted to the insertion portion 46B in an interference fit manner. The main body 271 has a quadrangular cylindrical shape, for example. Specifically, the main body 271 includes: a hollow portion 273 forming a space extending along the Z direction in which the reinforcing member 207 is inserted into the insertion portion 46B; and a quadrangular cylindrical outer cylinder 272 defining a hollow 273. The body 271 has a plate-like partition 274 that divides the hollow 273 into two spaces. The dividing portion 274 extends, for example, in the insertion direction of the reinforcing member 207 and extends along the ZX plane. The hollow portion 273 is formed in a through hole shape having both ends opened in the Z direction. The outer tube portion 272 has plate portions 272A, 272B, 272C, and 272D, and forms a quadrangular tube-shaped outer peripheral surface 271A extending parallel or substantially parallel to the Z direction. In the state where the reinforcing member 207 is attached to the insertion portion 46B, the plate portion 272A faces the wall portion 44B, the plate portion 272B faces the pillar portion 51, the plate portion 272C faces the wall portion 44C, and the plate portion 272D faces the wall portion 44D. The outward surfaces 2720A, 2720B, 2720C, and 2720D of the plate portions 272A, 272B, 272C, and 272D form an outer peripheral surface 271A.
The surfaces 2720A to 2720D of the plate portions 272A to 272D are provided with two protrusions 278, respectively, similarly to the reinforcing member 206. Protrusion 278 formed on surface 2720A protrudes toward wall 44B, and is formed to face wall 44B with a gap therebetween or to contact wall 44B. The protrusion 278 formed on the surface 2720B protrudes toward the pillar portion 51, and is formed to face the pillar portion 51 with a gap therebetween or to contact the pillar portion 51. Protrusions 78 formed on surfaces 2720C and 2720D protrude toward wall portions 44C and 44D, respectively, and are formed so as to face wall portions 44C and 44D with a gap therebetween or so as to contact wall portions 44C and 44D. In the plate portion 272A and the plate portion 272B, the projection portions 278 are formed symmetrically in the Y direction, and in the plate portion 272C and the plate portion 272D, the projection portions 278 are formed symmetrically in the X direction.
Specifically, the reinforcing member 7 has two restricting portions 275. For example, as shown in fig. 15, the restricting portion 275 is formed in a plate shape extending in the direction in which the reinforcing member 207 is inserted into the insertion portion 46B, and protrudes from the surface 2720A of the plate portion 272A in the direction orthogonal to the insertion direction of the reinforcing member 207. The restricting portion 275 is provided on an upper side, which is a rear side in the insertion direction, on the surface 2720A. The restricting portion 275 has, for example, a shape in which a portion of the Z-direction upper side of the plate portions 272C and 272D is extended so as to protrude from the plate portion 272A. That is, the reinforcing member 207 has a lower narrow width portion 276 not provided with the restricting portion 275, and an upper wide width portion 277 having a larger dimension in the X direction by providing the restricting portion 275. As described later, the restricting portion 275 is formed to be accommodated in the open portion 49 of the insertion portion 46B and to protrude from the open portion 49 to the outside of the insertion portion 46B in a state where the reinforcing member 207 is inserted into the insertion portion 46B and the lower end of the reinforcing member 207 is in contact with the bottom portion 45. In the illustrated example, the restricting portion 275 extends to the upper end 271B of the main body 271, but the restricting portion 275 may not reach the upper end 271B of the main body 271. The shape of the restricting portion 275 is not limited to a plate shape, and may be other shapes such as a rod shape and a block shape as long as the shape can be accommodated in the open portion 49. Further, the restricting portion 275 may not be formed at the end portions of the surfaces 2720A on the sides of the surfaces 2720C and D, or may be formed inside the surface 2720A.
As described above, in the state where the reinforcing members 206, 207 are fitted into the insertion portions 46A, 46B, the filler 8 is provided inside the hollow portions 261, 273, between the plate portions 262B, 272B and the pillar portions 51, 52, between the plate portions 262A, 272A and the wall portions 44A, 44B, between the plate portions 262C, 272C and the wall portion 44C, and between the plate portions 262D, 272D and the wall portion 44D. The filler 8 is an adhesive material made of, for example, a urethane adhesive, and includes a first adhesive material 81, a second adhesive material 82, and a third adhesive material 83. The first adhesive 81 is provided on the bottom portion 45 side, the second adhesive 82 is laminated on the treatment portion 2 side of the first adhesive 81, and the third adhesive 83 is laminated on the treatment portion 2 side of the second adhesive 82. As shown in fig. 12 and 20 to 22, the second adhesive 82 serves as the sealing portion 23 of the hollow fiber membrane bundle 4, and the third adhesive 83 is attached to the root portion of the hollow fiber membrane 21 at the sealing portion 23 for filling the groove upper portion 47A of the groove 47. The third adhesive 83 is attached to protect the hollow fiber membrane 21 and is attached to prevent the root portion of the hollow fiber membrane 21 from being broken or damaged by vibration.
The first adhesive 81 is more likely to be elastically deformed than the second adhesive 82, and the second adhesive 82 is harder than the first adhesive 81. Therefore, as described later, when the support body 3 is deformed, the deformation of each portion is easily allowed by the first adhesive material 81, and the deformation of each portion is suppressed by the second adhesive material 82. This makes it easy to suppress damage to the base end 43A of the placement portion 43 and the end 512 of the support portion 51. In addition, the third adhesive 83 is easily elastically deformed similarly to the first adhesive 81, and the third adhesive 83 flexibly holds the root portion of the hollow fiber membrane 21 and the sealing portion 23. In the present embodiment, the first adhesive 81 and the third adhesive 83 are the same adhesive, but may be different adhesives.
Next, the state of attachment in which the reinforcing members 206 and 207 are inserted into and attached to the insertion portions 46A and 46B, respectively, will be described in detail with reference to fig. 12, 13, and 16 to 19. Fig. 16 is a sectional view schematically showing the relationship between the reinforcing member 207 and the insertion portion 46B, and fig. 17 is a sectional view schematically showing the relationship between the reinforcing member 206 and the insertion portion 46A. Fig. 18 is a sectional view schematically showing a case where the reinforcing member 206 is to be misassembled to the insertion portion 46B, and fig. 19 is a sectional view schematically showing a case where the reinforcing member 207 is to be misassembled to the insertion portion 46A. The reinforcing members 206 and 207 are fitted into the insertion portions 46A and 46B to determine the orientation of the hollow fiber membrane module 201, but in the following description, the dimensions and the like of the respective portions will be described with the reinforcing members 206 and 207 in the mounted state.
As shown in fig. 16, the dimension in the X direction of the narrow width portion 276 of the reinforcing member 207 is defined as a width L1, and the dimension in the X direction of the wide width portion 277 is defined as a width L2. The dimension in the Z direction of the narrow portion 276 where the restricting portion 275 of the main body 271 is not formed is set to the height H. As shown in fig. 17, the entire reinforcing member 206 has a width L3 in the X direction. The widths L1 to L3 are set to dimensions including the protrusions 263 and 278. As shown in fig. 16, the width of insertion portion 46B is W1, and the depth of insertion portion 46B is D1. As shown in fig. 17, the width of insertion portion 46A is W2, and the depth of insertion portion 46A is D2. The width of the insertion portion 46B is the distance between the pillar portion 51 and the wall portion 44B in the X direction, and the depth of the insertion portion 46B is the projection dimension of the wall portion 44B from the bottom portion 45 in the Z direction. The width of the insertion portion 46A is the distance between the pillar portion 51 and the wall portion 44A in the X direction, and the depth of the insertion portion 46A is the projection dimension of the wall portion 44A from the bottom portion 45 in the Z direction.
As shown in fig. 12 and 16, an opening portion 49 that opens the insertion portion 46B in the X direction is formed in the wall portion 44B, and the wall portion 44B is lower than the other wall portions 44C and 44D of the insertion portion 46B. The open portion 49 is formed so as to be able to insert the regulating portion 275 of the reinforcing member 207 in the insertion direction and also open to the open side (upper side) of the insertion portion 46B. Specifically, the opening portion 49 is formed in the wall portion 44B at the end portion of the insertion portion 46B on the opening side. The opening portion 49 is formed over the entire width of the wall portion 44B in the Y direction, but may not be formed over the entire width of the wall portion 44B in the Y direction. The width L1 of the narrow portion 276 is equal to or less than the width W1 of the insertion portion 46B, so that the narrow portion 276 in the reinforcing member 207 can be inserted into the insertion portion 46B. The width L1 of the narrow portion 276 may be larger than the width W1 of the insertion portion 46B as long as the body portion 271 can be inserted into the insertion portion 46B. On the other hand, although the width L2 of the wide portion 277 from which the restricting portion 275 projects is larger than the width W1 of the insertion portion 46B, the height H of the narrow portion 276 is equal to or greater than the depth D1 of the insertion portion 46B, and therefore the restricting portion 275 is accommodated in the open portion 49 without interfering with the wall portion 44B, and the reinforcing member 207 is inserted into the insertion portion 46B. In a state where the reinforcing member 207 is inserted and attached into the insertion portion 46B, the restricting portion 275 protrudes outward of the insertion portion 46B in the X direction through the open portion 49. On the other hand, as shown in fig. 17, the reinforcing member 206 can be inserted into the insertion portion 46A by setting the width L3 of the reinforcing member 206 to be equal to or less than the width W2 of the insertion portion 46A. The width L3 of the reinforcing member 206 may be larger than the width W2 of the insertion portion 46A as long as the reinforcing member 206 can be inserted into the insertion portion 46A. Fig. 13 shows a cross section of the reinforcing member 207 on the narrow-width portion 276 side.
Next, a case where the reinforcing members 206 and 207 are erroneously assembled will be described. As shown in fig. 18, since the width L3 of the reinforcing member 206 is larger than the width W1 of the insertion portion 46B, the reinforcing member 206 cannot be inserted into the insertion portion 46B, and erroneous assembly can be suppressed. Further, as shown in fig. 19, the width L1 of the narrow-width portion 276 in the reinforcing member 207 is smaller than the width W2 of the insertion portion 46A, so the narrow-width portion 276 can be inserted into the insertion portion 46A. However, since the height H of the narrow-width portion 276 is smaller than the depth D2 of the insertion portion 46A and the width L2 of the wide-width portion 277 of the restricting portion 275 is larger than the width W2 of the insertion portion 46A, the restricting portion 275 comes into contact with the wall portion 44A when the reinforcing member 207 is inserted into the insertion portion 46A. Thus, even if the body 271 can be inserted into the insertion portion 46A, the insertion of the reinforcing member 207 into the insertion portion 46A can be restricted. Therefore, the entire reinforcing member 207 cannot be inserted into the insertion portion 46A, and erroneous assembly can be suppressed.
The width L1 of the main body 271 of the reinforcing member 207 is preferably about 0.1 to 3mm smaller, more preferably about 0.5 to 2mm smaller, than the width W1 of the insertion portion 46B. Similarly, the width L3 of the reinforcing member 206 is preferably about 0.1 to 3mm smaller, more preferably about 0.5 to 2mm smaller, than the width W2 of the insertion portion 46A. The Y-direction dimensions of the main body 271 of the reinforcing member 207 and the reinforcing member 206 are preferably smaller by about 0.1 to 3mm, more preferably about 0.5 to 2mm, with respect to the insertion portions 46B and 46A, respectively. In this way, by setting the X-direction dimension and the Y-direction dimension of the body portions 271 of the reinforcing member 206 and the reinforcing member 207 smaller than the corresponding dimensions of the insertion portions 46A, 46B, the workability when inserting the reinforcing members 206, 207 into the insertion portions 46A, 46B, respectively, can be improved.
By forming the protruding portions 263 and 278 in the reinforcing members 206 and 207, gaps are formed between the surfaces 2620A to 2620D and the wall portion 44A, the pillar portion 51, the wall portion 44C, and the wall portion 44D which face each other, and gaps are formed between the surfaces 2720A to 2720D and the wall portion 44B, the pillar portion 51, the wall portion 44C, and the wall portion 44D which face each other. Specifically, a gap is inevitably formed between the portion of the surface 2620B other than the protruding portion 263 and the column portion 51, a gap is inevitably formed between the portion of the surface 2620A other than the protruding portion 263 and the wall portion 44A, a gap is inevitably formed between the portion of the surface 2620C other than the protruding portion 263 and the wall portion 44C, and a gap is inevitably formed between the portion of the surface 2620D other than the protruding portion 263 and the wall portion 44D. Further, a gap is inevitably formed between the portion of the surface 2720B other than the projecting portion 278 and the pillar portion 51, a gap is inevitably formed between the portion of the surface 2720A other than the projecting portion 278 and the wall portion 44B, a gap is inevitably formed between the portion of the surface 2720C other than the projecting portion 278 and the wall portion 44C, and a gap is inevitably formed between the portion of the surface 2720D other than the projecting portion 278 and the wall portion 44D. By forming the gaps around the reinforcing members 206 and 207 in this manner, it is easier to fill the filler 8 around the reinforcing members 206 and 207 inserted into the insertion portions 46A and 46B, respectively, than in the case where no gaps are formed. Two protrusions 263 and 278 are provided on each surface of the reinforcing members 206 and 207. Therefore, since the two projecting portions 263 and 278 are interposed between the respective surfaces of the reinforcing members 206 and 207 and the respective surfaces of the reinforcing members 206 and 207 on the side of the holding members 41 and 42 facing each other, the gap interval around the reinforcing members 206 and 207 can be maintained at a constant interval or more.
When a force in the X direction, for example, acts on the hollow fiber membrane module 201, the rectangular frame-shaped support 3 is also deformed into a parallelogram shape. That is, the support portions 51 and 52 swing with respect to the holding portions 41 and 42. In such a rocking motion, the arrangement portion 43 is easily deformed, and the load is easily concentrated on the base end portion 43A of the arrangement portion 43.
By providing the hollow fiber membrane module 201 with the reinforcing members 206 and 207, the swinging of the column parts 51 and 52 with respect to the holding parts 41 and 42 can be suppressed. Since the insertion portions 46A and 46B are formed in the connecting portion 30, when the column portions 51 and 52 are assembled to the holding portions 41 and 42, respectively, a gap can be secured between the column portions 51 and 52 and the wall portions 44A and 44B, and the assembling property can be improved, and the insertion portions 46A and 46B are spaces where the reinforcing members 206 and 207 are provided.
Further, since the protrusions 263 and 278 are formed on the reinforcing members 206 and 207, the filler 8 can be easily filled as described above, and the adhesiveness between the reinforcing members 206 and 207 and the column parts 51 and 52 and the wall parts 44A, 44B, 44C, and 44D can be improved. This can prevent the column parts 51 and 52 from easily wobbling due to the separation of the filler 8. That is, deformation of the support 3 can be suppressed, the arrangement portion 43 and the like are not easily damaged, and the durability of the hollow fiber membrane module 201 can be improved.
Further, since the reinforcing members 206, 207 have the dividing portions 264, 274 extending along the ZX plane and dividing the hollow portions 261, 271, respectively, even if an external force generated by the swinging of the column portions 51, 52 is applied to the reinforcing members 206, 207, deformation such as crushing of the hollow portions 261, 271 is less likely to occur, and the rigidity of the reinforcing members 206, 207 can be improved, whereby the swinging of the column portions 51, 52 can be suppressed.
As described above, according to the hollow fiber membrane module 201 of the second embodiment of the present invention, the reinforcing members 206 and 207 are provided at the connection portion 30, and the durability can be improved by the reinforcing members 206 and 207. Further, since the reinforcing member 207 has the restricting portion 275, erroneous insertion of the reinforcing member 207 into the insertion portion 46A can be suppressed, and the assembling property can be improved.
Further, since the protrusions 263 and 278 are formed on the reinforcing members 206 and 207, the durability of the hollow fiber membrane module 201 can be improved.
Further, since the reinforcing members 206 and 207 have the dividing portions 264 and 274, the strength of the reinforcing members 206 and 207 can be improved, and the durability of the hollow fiber membrane module 201 can be further improved.
As shown in fig. 20 to 22, the connection portions 32, 33, and 34 have the same configuration as the connection portion 31, but the connection portion 31 is different from the connection portion 32 and the connection portion 33 is different from the connection portion 34 in the configuration in which the flow path between the holding portion 41 and the support portions 51 and 52 is formed or the configuration in which the flow path between the holding portion 42 and the support portions 51 and 52 is formed. In the connection portion 31 shown in fig. 12 and 13 described above, the portion of the groove lower portion 47B adjacent to the bottom portion 45 and the portion of the groove lower portion 47B adjacent to the bottom portion 45 communicate with each other. The disposition portion 43 has a hollow portion 43C penetrating the base end portion 43A and the tip end portion 43B, and the hollow portion 43C of the disposition portion 43 penetrates the bottom portion 45 and communicates with the groove lower portion 47B as a flow path from the hollow fiber membrane 21.
On the other hand, as shown in fig. 20, the connecting portion 32 provided at the end 411 of the holding portion 41 connected to the suction pump is provided with a partition wall 48, and the partition wall 48 is a plate-shaped portion that partitions a portion of the groove lower portion 47B adjacent to the bottom portion 45 and a portion of the groove lower portion 47B adjacent to the bottom portion 45. Thus, the liquid filtered by the hollow fiber membranes 21 and rising in the column part 51 is directed toward the connection port 410 without flowing to the groove lower part 47B of the holding part 41 communicating with the hollow fiber membranes 21. The partition wall 48 may not be provided in the connection portion 32.
As shown in fig. 21, the connection portion 33 provided at the other end 412 of the holding portion 41 connected to the suction pump has the same configuration as the connection portion 31 provided at the end 421 of the holding portion 42. Specifically, the portion of the groove lower portion 47B adjacent to the bottom portion 45 communicates with the portion of the groove lower portion 47B adjacent to the bottom portion 45, and the hollow portion 43C of the arrangement portion 43 penetrates the bottom portion 45 and communicates with the groove lower portion 47B of the holding portion 41 serving as a flow path from the hollow fiber membrane 21. Thus, at the end 412 of the holding portion 41, the liquid filtered by the hollow fiber membranes 21 and rising through the hollow fiber membranes 21 flows from the end 411 side to the end 412 side in the groove lower portion 47B of the holding portion 41, and goes toward the connection port 410. For example, the connection portion 31 and the connection portion 33 are common members that are common to each other, and the common members change the mounting position, the mounting direction to function as the connection portion 31 or the connection portion 33. The connection portion 31 and the connection portion 33 may not be common members common to each other.
As shown in fig. 22, the connection portion 34 provided at the end 422 of the lower holding portion 42 has the same configuration as the connection portion 32 provided at the end 411 of the holding portion 41. Specifically, a partition wall 48 is provided, and the partition wall 48 is a plate-like portion that partitions a portion of the groove lower portion 47B adjacent to the bottom portion 45 and a portion of the groove lower portion 47B adjacent to the bottom portion 45. Further, the connection port 410 of the end 422 of the holding portion 42 is closed by the plug 9. This prevents the liquid filtered by hollow fiber membranes 21 and descending through hollow fiber membranes 21 from flowing through groove lower 47B of holding part 42 communicating with hollow fiber membranes 21 and flowing out from connection port 410 on the side of end 422 of holding part 42, and prevents the liquid descending through support column 52 from flowing out from connection port 410 on the side of end 422 of holding part 42 without flowing through groove lower 47B of holding part 42 communicating with hollow fiber membranes 21. For example, the connection portion 32 and the connection portion 34 are common members that are common to each other, and the common members change the mounting position, mounting direction to function as the connection portion 32 or the connection portion 34. The connection portion 32 and the connection portion 34 may not be common components common to each other. The partition wall 48 may not be provided in the connection portion 34.
The present invention is not limited to the second embodiment of the present invention described above, and includes other configurations and the like that can achieve the object of the present invention, and modifications and the like shown below are also included in the present invention. For example, in the second embodiment of the present invention described above, the insertion portion 46A and the insertion portion 46B sandwich the column portions 51 and 52 in the X direction, respectively, but the insertion portion 46A and the insertion portion 46B may sandwich the column portions 51 and 52 in the Y direction, respectively. In this case, the opening portion 49 of the insertion portion 46B is formed in the wall portion 44C or the wall portion 44D similarly, and the restricting portion 275 is formed in the surface 2720C or the surface 2720D of the body portion 271 of the reinforcing member 207 similarly corresponding to the opening portion 49. Even when the column portions 51 and 52 are sandwiched between the insertion portion 46A and the insertion portion 46B in the X direction, the insertion portion 46B may be formed outside the insertion portion 46A. In this case, the restricting portion 275 projects outward of the insertion portion 46B on the opposite side to the case shown in fig. 12 described above.
In the second embodiment of the present invention described above, the wall portion 44B of the insertion portion 46B into which the reinforcing member 207 having the regulating portion 275 is inserted is formed to have a lower wall height than the wall portion 44A of the insertion portion 46A into which the reinforcing member 206 not having the regulating portion is inserted, thereby forming the open portion 49, but the form of the open portion 49 is not limited to this form. For example, the wall height D1 of the wall portion 44B may be set to be greater than the height H of the narrow portion 276 of the reinforcing member 207, and the opening portion 49 may be formed by forming a slit-like notch or the like in the wall portion 44B corresponding to the restricting portion 275.
In the second embodiment of the present invention described above, the restricting portion 275 is formed in a plate shape, but the shape of the restricting portion is not limited as long as it protrudes from the main body portion, and may be, for example, a rod shape or a block shape.
In the second embodiment of the present invention described above, the reinforcing members 206 and 207 have the wall- like dividing portions 264 and 274 extending along the insertion direction, but the dividing portions dividing the hollow portion may have other shapes as long as they generate a force against the swinging of the column portions 51 and 52. For example, the dividing portion may have a dimension in the Z direction smaller than the dimension in the Z direction of the entire reinforcing member, or the dividing portion may be formed in a rod shape extending in the X direction. The dividing portion may extend in a direction inclined to the insertion direction, or may extend in a direction orthogonal to the insertion direction. The reinforcing members 206 and 207 may have a plurality of divided portions. Further, for example, in the case where the reinforcing member is difficult to deform sufficiently, such as the case where the thickness of the outer tube portion is sufficiently large, the case where the strength of the material of the reinforcing member is high, and the case where the size of the reinforcing member is small, the partitioning portion may not be formed.
In the second embodiment of the present invention described above, the reinforcing members 206 and 207 have a cylindrical shape having the hollow portions 261 and 273, but the shape of the reinforcing member of the present invention is not limited to a cylindrical shape. The reinforcing member may be formed in a bottomed cylindrical shape (cup shape) having an opening on one side (upper side or lower side) in the insertion direction, or may be formed in a block shape having no opening. In addition, in the bottomed cylindrical reinforcing member, a recessed (non-penetrating) hollow portion may be formed, and a partitioning portion for partitioning the hollow portion may be provided. Further, the hollow portion or the concave portion of the reinforcing member may be filled with a filler.
In the second embodiment of the present invention described above, the placement portion 43 protrudes in a cylindrical shape and is inserted into the support portions 51 and 52, but the placement portion may have a shape that allows the support portions to be placed. For example, a groove or a recess may be formed in the bottom portion 45 and the pillar portion may be inserted, and the groove or the recess may be used as the arrangement portion. That is, the placement portion may be any portion as long as it can position the column portion. Further, the support column portion may not be provided.
In the reinforcing member, a plurality of the protrusions may be provided at intervals in the insertion direction (Z direction), or three or more protrusions may be provided on one surface. In the reinforcing member, the protrusion may extend obliquely in the insertion direction (Z direction), or may extend in a curved manner instead of linearly. The protrusion may extend in a direction orthogonal to the insertion direction. The reinforcing member may not have the projection. In this case, each surface of the outer cylinder portion is formed to be in contact with or close to the wall portion or the pillar portion of the corresponding insertion portion, similarly to the above-described protrusion portion.
In addition, two or more insertion portions 46A and 46B may be provided in all of the connection portions 30 or in any one of the connection portions 30. In the case where two or more insertion portions 46A are provided, the plurality of insertion portions 46A may not be all the same size, and similarly, in the case where two or more insertion portions 46B are provided, the plurality of insertion portions 46B may not be all the same size.
In the second embodiment of the present invention described above, the reinforcing members 206 and 207 are provided in all the connection portions 30, but the reinforcing members 206 and 207 may not be provided in the connection portions 30 where the generated load is small. In addition, the connecting portion may be selectively provided in each connecting portion from among the connecting portion 30 provided with the reinforcing members 206 and 207, the connecting portion 30 provided with only one of the insertion portion 46A and the insertion portion 46B, and the connecting portion 30 not provided with the reinforcing members 206 and 207. Further, the connection unit may be selectively provided from the connection units 31, 32, 33, and 34.
Hereinafter, a third embodiment of the present invention will be described with reference to the drawings. The same reference numerals are given to members having the same functions as or the same as those of the hollow fiber membrane module 1 according to the first embodiment of the present invention, and the description thereof will be omitted.

As shown in fig. 23, a hollow fiber membrane module 301 according to a third embodiment of the present invention includes: a plurality of hollow fiber membranes 21; and a support body 3 that supports the plurality of hollow fiber membranes 21 so as to align the plurality of hollow fiber membranes 21. The support body 3 includes a pair of holding portions 41 and 42, a pair of column portions 51 and 52, and at least one reinforcing member 306. The pair of holding portions 41 and 42 are members for holding the pair of end portions 21A and 21B of the hollow fiber membrane 21, respectively. The pair of support portions 51 and 52 are connected to the pair of holding portions 41 and 42, respectively, and support the pair of holding portions 41 and 42 such that the pair of holding portions 41 and 42 face each other. The reinforcing member 306 is a member for reinforcing the connection between the holding portions 41, 42 and the column portions 51, 52. The holding portions 41 and 42 are provided with connection portions 30 formed so as to be able to connect the pair of column portions 51 and 52, respectively. A plurality of insertion portions 46A, 46B are formed in at least one of the connection portions 30, and the insertion portions 46A, 46B form a gap formed so that the reinforcing member 306 can be inserted. Reinforcing member 306 has a protruding portion 365 that protrudes in a direction that intersects the insertion direction of reinforcing member 306. A part of the plurality of insertion portions 46A, 46B (insertion portion 46B) is formed with an open portion 49 that projects outward of the insertion portion 46B from a protruding portion 365 of the reinforcing member 306 inserted into the insertion portion 46B. The other insertion portion 46A is formed so that the reinforcing member 306 including the protruding portion 365 can be inserted. Hereinafter, the hollow fiber membrane module 1 will be specifically described.
As shown in fig. 23 and 24, the connection portion 31 at the end 421 of the holding portion 42 includes: a placement portion 43 on which an end 512 of the pillar portion 51 is disposed; and wall portions 44A to 44D that face the pillar portion 51 disposed in the arrangement portion 43 to form a space ( insertion portions 46A and 46B) adjacent to the pillar portion 51, and the reinforcing member 306 is formed to be inserted into and attached to the insertion portions 46A and 46B that form the space. Specifically, the connecting portion 31 is formed with an arrangement portion 43 protruding toward the upper side in the Z direction, a pair of wall portions 44A, 44B facing each other in the X direction across the arrangement portion 43, and a pair of wall portions 44C, 44D facing each other in the Y direction across the arrangement portion 43. A predetermined distance is provided between each of the pair of wall portions 44A, 44B and the arrangement portion 43, and the distance in the X direction between the wall portion 44A on one side (outer side) in the X direction and the arrangement portion 43 is larger than the distance in the X direction between the wall portion 44B on the other side (inner side) in the X direction and the arrangement portion 43. The arrangement portion 43 and the pair of wall portions 44A, 44B protrude from the common bottom portion 45, the pair of wall portions 44A, 44B are formed higher than the arrangement portion 43 and have a larger protruding dimension, and the wall portion 44A is formed higher than the wall portion 44B. The wall portions 44C and 44D are portions of a pair of side surfaces extending in the longitudinal direction of the holding portion 42. The bottom portion 45 is a plate-like portion provided to face the bottom wall 42A of the holding portion 42 with a space. The bottom wall 42A is a portion forming the bottom of the groove 47 in the holding portion 42. The bottom portion 45 may be provided at a joint portion between the groove upper portion 47A and the groove lower portion 47B in the groove 47, or may be provided at an upper side or a lower side of the joint portion.
The arrangement portion 43 has a shape that can be inserted or press-fitted into the opening 512A of the end portion 512 of the column portion 51. The arrangement portion 43 has a shape corresponding to the opening 512A of the pillar portion 51, and has, for example, a quadrangular tube shape. In a state where the placement portion 43 is inserted into the opening 512A, an insertion portion 46A is formed by the pillar portion 51, the wall portion 44A, the wall portion 44C, the wall portion 44D, and the bottom portion 45, the insertion portion 46A being a space opened to the upper side in the Z direction, and similarly, an insertion portion 46B is formed by the pillar portion 51, the wall portion 44B, the wall portion 44C, the wall portion 44D, and the bottom portion 45, the insertion portion 46B being a space opened to the upper side in the Z direction. Further, a gap may be formed between the pillar portion 51 and the pair of wall portions 44C and 44D, or no gap may be formed. As described above, the X-direction dimension of the outer insertion portion 46A is larger than the X-direction dimension of the inner insertion portion 46B, and the Y-direction dimensions thereof are the same or substantially the same. Thus, the insertion portion 46A and the insertion portion 46B have different sizes from each other.
As described above, in the hollow fiber membrane module 301 according to embodiment 3, the two insertion portions 46A and 46B are provided in the connection portion 31. In the connecting portion 31, an insertion portion 46B having a small width in the extending direction is provided on the inner side (wall portion 44B side) in the extending direction (X direction) of the holding portion 42, and an insertion portion 46A having a large width in the extending direction is provided on the outer side (wall portion 44A side) in the extending direction (X direction) of the holding portion 42. As described later, the insertion portion 46B is formed with an open portion 49 for guiding the protruding portion 365 of the reinforcing member 306.
As shown in fig. 25, the reinforcing member 306 has a protrusion 365, and further has a main body 361, and the main body 361 is a portion forming an outer peripheral surface 361A, and the outer peripheral surface 361A is a surface along a direction (Z direction) in which the reinforcing member 306 is inserted into the insertion portions 46A, 46B. The reinforcing member 306 is formed to be inserted and attached to the insertion portions 46A, 46B, and the reinforcing member 306 is provided in both of the insertion portions 46A, 46B. Specifically, the reinforcing member 306 is formed in a shape to be fitted to the insertion portion 46A in a state of being fitted with a clearance or fitting in the middle at a portion where the protruding portion 365 is provided. The reinforcing member 306 may be formed in such a shape as to be fitted to the insertion portion 46A in a state of interference fit at a portion where the protruding portion 365 is provided. The reinforcing member 306 is attached to the insertion portion 46B in the main body 361 in a state of being fitted with a gap or an intermediate fit. The reinforcing member 306 may be fitted to the insertion portion 46B in the main body 361 by interference fit. As also shown in fig. 25, the reinforcing member 306 has: a hollow section 363 that forms a space extending along the Z direction in which the reinforcing member 306 is inserted into the insertion sections 46A, 46B; and a quadrangular cylindrical outer cylinder 362 defining a hollow 363. The body 361 has a plate-like partition 364 that divides the hollow 363 into two spaces. The dividing portion 364 extends, for example, in the insertion direction of the reinforcing member 306, and along the ZX plane. The hollow portion 363 is formed in a through hole shape having both ends opened in the Z direction. The outer tube 362 has plate portions 362A, 362B, 362C, and 362D, and forms a quadrangular tube-shaped outer peripheral surface 361A extending parallel or substantially parallel to the Z direction. As shown in fig. 24, in a state where the reinforcing member 306 is attached to the insertion portions 46A, 46B, the plate portion 362A faces the wall portions 44A, 44B, the plate portions 362B face the pillar portion 51, and the plate portions 362C, 362D face the wall portions 44C, 44D or the wall portions 44D, 44C, respectively. The reinforcing member 306 can be inserted into the insertion portion 46A even when the protruding portion 365 is oriented in any direction in the X direction, but as shown in fig. 23 and 24, the reinforcing member 36 is preferably attached to the insertion portions 46A and 46B so that the protruding portions 365 extend toward the sides separated from each other.
Two projecting portions 368 are provided on the outward surfaces 3620A to 3620D of the plate portions 362A to 362D, respectively, and the projecting portions 368 project toward the side opposite to the hollow portion 363 side. In a state where reinforcing member 306 is attached to insertion portion 46B, protrusion 368 formed on surface 3620A protrudes toward wall portion 44B, and is formed to face wall portion 44B with a gap therebetween, or is formed to contact wall portion 44B. In a state where the reinforcing member 306 is attached to the insertion portion 46B, the protrusion 368 formed on the surface 3620B protrudes toward the column portion 51, and is formed to face the column portion 51 with a gap therebetween, or is formed to contact the column portion 51. As shown in fig. 24, in a state where the reinforcing member 306 is attached to the insertion portion 46A, the protrusion 368 formed on the surface 3620B protrudes toward the column portion 51, and is formed to face the column portion 51 with a gap therebetween, or is formed to contact the column portion 51. In the state where reinforcing member 306 is attached to insertion portion 46A or insertion portion 46B, protrusions 368 formed on surfaces 3620C and 3620D protrude toward wall portions 44C and 44D or wall portions 44D and 44C, respectively, and are formed so as to face wall portions 44C and 44D or wall portions 44D and 44C with a gap therebetween, or so as to contact wall portions 44C and 44D or wall portions 44D and 44C. The plate portions 362A and 362B have the protruding portions 368 formed symmetrically in the Y direction, and the plate portions 362C and 362D have the protruding portions 368 formed symmetrically in the X direction.
Specifically, the reinforcing member 306 has two protrusions 365. As shown in fig. 25, for example, the projecting portion 365 is formed in a plate shape extending in the direction in which the reinforcing member 306 is inserted into the insertion portions 46A and 46B, and projects from the surface 3620A of the plate portion 362A in the direction orthogonal to the insertion direction of the reinforcing member 306. The protruding portion 365 is provided on the upper side, which is the insertion direction rear side, on the face 3620A. The protruding portion 365 has, for example, a shape in which a part of the Z-direction upper side of the plate portions 362C and 362D is extended to protrude from the plate portion 362A. That is, the reinforcing member 306 has a lower narrow width portion 366 not provided with the projecting portion 365, and an upper wide width portion 367 increased in the X-direction dimension by providing the projecting portion 365. As described later, the projecting portion 365 is formed to be accommodated in the open portion 49 of the insertion portion 46B and project from the open portion 49 to the outside of the insertion portion 46B in a state where the reinforcing member 306 is inserted into the insertion portion 46B and the lower end of the reinforcing member 306 is in contact with the bottom portion 45. As described later, the reinforcing member 306 is formed such that the entire reinforcing member 306 is accommodated in the insertion portion 46A in a state where the reinforcing member 306 is inserted into the insertion portion 46A and the lower end of the reinforcing member 306 is in contact with the bottom portion 45. As shown in fig. 23 and 24, in this attached state of reinforcing member 306, tip 365A of protrusion 365 is formed to face wall 44A with a gap therebetween, or to contact wall 44A.
In the illustrated example, the protrusion 365 extends to the upper end 361B of the main body 361, but the protrusion 365 may not reach the upper end 361B of the main body 361. The shape of the protruding portion 365 is not limited to a plate shape, and may be other shapes such as a rod shape and a block shape as long as it can be accommodated in the opening portion 49. The protrusion 365 may not be formed at the end of the surface 3620A on the side of the surfaces 3620C and D, but may be formed inside the surface 3620A.
As described above, the reinforcing member 306 is inserted into the insertion portion 46A such that the plate portion 362B faces the pillar portion 51 side and the plate portion 362A faces the wall portion 44A side. At this time, the entire reinforcing member 306 is inserted into the insertion portion 46A. The reinforcing member 306 is inserted into the insertion portion 46B such that the plate portion 362B faces the pillar portion 51 side and the plate portion 362A faces the wall portion 44B side. At this time, only the narrow-width portion 366 of the main body portion 361 in the reinforcing member 306 is inserted into the insertion portion 46B.
As described above, in the state where the reinforcing member 306 is fitted into the insertion portions 46A, 46B, the filler 8 is provided inside the hollow portion 363, between the plate portion 362B and the column portion 51, between the plate portion 362A and the wall portions 44A, 44B, and between the plate portions 362C, 362D and the wall portions 44C, 44D or between the plate portions 44D, 44C. The filler 8 is an adhesive material made of, for example, a urethane adhesive, and includes a first adhesive material 81, a second adhesive material 82, and a third adhesive material 83. The first adhesive 81 is provided on the bottom portion 45 side, the second adhesive 82 is laminated on the treatment portion 2 side of the first adhesive 81, and the third adhesive 83 is laminated on the treatment portion 2 side of the second adhesive 82. As shown in fig. 23 and 29 to 31, the second adhesive 82 serves as the sealing portion 23 of the hollow fiber membrane bundle 4, and the third adhesive 83 is attached to the root portion of the hollow fiber membrane 21 at the sealing portion 23 for filling the groove upper portion 47A of the groove 47. The third adhesive 83 is attached to protect the hollow fiber membranes 21 and is attached to prevent the root portions of the hollow fiber membranes 21 from being broken or damaged by vibration.
The first adhesive 81 is more easily elastically deformed than the second adhesive 82, and the second adhesive 82 is harder than the first adhesive 81. Therefore, as described later, when the support body 3 is deformed, the deformation of each portion is easily allowed by the first adhesive material 81, and the deformation of each portion is suppressed by the second adhesive material 82. This makes it easy to suppress damage to the proximal end portion 43A of the arrangement portion 43 and the end portion 512 of the column portion 51. In addition, the third adhesive 83 is easily elastically deformed similarly to the first adhesive 81, and the third adhesive 83 flexibly holds the root portion of the hollow fiber membrane 21 and the sealing portion 23. In the present embodiment, the first adhesive 81 and the third adhesive 83 are the same adhesive, but may be different adhesives.
Next, the mounting state in which the reinforcing member 306 is inserted into and mounted on the insertion portions 46A and 46B will be described in detail with reference to fig. 23, 24, and 26 to 28. The reinforcing member 306 is fitted into the insertion portions 46A and 46B to determine the orientation of the hollow fiber membrane module 301, but in the following description, the dimensions and the like of the respective portions will be described assuming a posture in which the reinforcing member 306 is in the attached state.
As shown in fig. 26, the X-direction dimension of the narrow-width portion 366 of the reinforcing member 306 (the X-direction dimension of the main body 361) is set to a width L11, and the X-direction dimension of the wide-width portion 367 (the X-direction dimension including the main body 361 and the protruding portion 365) is set to a width L12. The dimension in the Z direction of the narrow part 366, in which the protruding part 365 of the main body 361 is not formed, is set to be the height H. The widths L11 and L12 are set to have a size including the projection 368. As shown in fig. 27, the width of insertion portion 46B is W1, and the depth of insertion portion 46B is D1. As shown in fig. 28, the width of insertion portion 46A is W2, and the depth of insertion portion 46A is D2. The width of the insertion portion 46B is the distance between the pillar portion 51 and the wall portion 44B in the X direction, and the depth of the insertion portion 46B is the projection dimension of the wall portion 44B from the bottom portion 45 in the Z direction. The width of the insertion portion 46A is the distance between the pillar portion 51 and the wall portion 44A in the X direction, and the depth of the insertion portion 46A is the projection dimension of the wall portion 44A from the bottom portion 45 in the Z direction.
As shown in fig. 23 and 27, an opening portion 49 that opens the insertion portion 46B in the X direction is formed in the wall portion 44B, and the wall portion 44B is lower than the other wall portions 44C and 44D of the insertion portion 46B. The open portion 49 is formed so that the protruding portion 365 of the reinforcing member 306 can be inserted in the insertion direction, and is also open to the open side (upper side) of the insertion portion 46B. Specifically, the opening portion 49 is formed in the end portion of the wall portion 44B on the opening side of the insertion portion 46B. The opening portion 49 is formed over the entire width of the wall portion 44B in the Y direction, but may not be formed over the entire width of the wall portion 44B in the Y direction. The width L11 of the narrow-width portion 366 is equal to or less than the width W1 of the insertion portion 46B, whereby the narrow-width portion 366 of the reinforcing member 306 can be inserted into the insertion portion 46B. The width L11 of the narrow part 366 may be larger than the width W1 of the insertion part 46B as long as the body 361 can be inserted into the insertion part 46B. On the other hand, although the width L12 of the wide width portion 367 from which the projecting portion 365 projects is larger than the width W1 of the insertion portion 46B, the height H of the narrow width portion 366 is equal to or greater than the depth D1 of the insertion portion 46B, and therefore the projecting portion 365 is accommodated in the open portion 49 without interfering with the wall portion 44B, and the reinforcing member 306 is inserted into the insertion portion 46B.
On the other hand, by setting the width L12 of the wide width portion 367 to be equal to or less than the width W2 of the insertion portion 46A, the wide width portion 367 of the reinforcing member 306 can be inserted into the insertion portion 46A, and the entire reinforcing member 306 can be accommodated. Note that the depth D2 of the insertion portion 46A may be larger than the height H of the narrow width portion 366, and a part of the wide width portion 367 of the reinforcing member 306 (a part of the protrusion 365) may be accommodated in the insertion portion 46A. The width L12 of the reinforcing member 306 may be larger than the width W2 of the insertion portion 46A as long as the reinforcing member 306 can be inserted into the insertion portion 46A at the wide width portion 367.
The width L11 of the main body 361 of the reinforcing member 306 is preferably about 0.1 to 3mm smaller, more preferably about 0.5 to 2mm smaller, than the width W1 of the insertion portion 46B. Similarly, the width L12 of the wide width portion 367 of the reinforcing member 306 is preferably smaller by about 0.1 to 3mm, more preferably about 0.5 to 2mm, than the width W2 of the insertion portion 46A. The Y-direction dimension of the main body 361 of the reinforcing member 306 is preferably about 0.1 to 3mm smaller, more preferably about 0.5 to 2mm smaller, than the insertion portions 46B and 46A. In this way, by setting the X-direction dimension and the Y-direction dimension of the main body 361 of the reinforcing member 306 to be smaller than the corresponding dimensions of the insertion portions 46A, 46B, respectively, the workability when inserting the reinforcing member 306 into the insertion portions 46A, 46B can be improved.
By forming protrusion 368 in reinforcing member 306, gaps are formed between surfaces 3620B to 3620D and respectively opposing pillar portion 51, wall portion 44C, and wall portion 44D in insertion portion 46A, and gaps are formed between surfaces 3620A, 3620B, 3620D, and 3620C and respectively opposing wall portion 44B, pillar portion 51, wall portion 44C, and wall portion 44D in insertion portion 46B. Specifically, in the insertion portion 46A, a gap is inevitably formed between the portion of the surface 3620B other than the protrusion 368 and the pillar portion 51, a gap is inevitably formed between the portion of the surface 3620C other than the protrusion 368 and the wall portion 44C, and a gap is inevitably formed between the portion of the surface 3620D other than the protrusion 368 and the wall portion 44D. In the insertion portion 46B, a gap is inevitably formed between the portion of the surface 3620B other than the protrusion 368 and the pillar portion 51, a gap is inevitably formed between the portion of the surface 3620A other than the protrusion 368 and the wall portion 44B, a gap is inevitably formed between the portion of the surface 3620C other than the protrusion 368 and the wall portion 44D, and a gap is inevitably formed between the portion of the surface 3620D other than the protrusion 368 and the wall portion 44C. By forming the gap around the reinforcing member 306 in this way, the filler 8 is more easily filled around the reinforcing member 306 inserted into the insertion portions 46A and 46B, respectively, than in the case where the gap is not formed. Two projections 368 are provided on each surface of the reinforcing member 306. Therefore, the two projecting portions 368 are interposed between the respective surfaces of the reinforcing member 306 and the respective surfaces of the reinforcing member 306 on the side of the holding members 41 and 42 facing each other, and therefore the gap interval around the reinforcing member 306 can be maintained at a constant interval or more.
When a force in the X direction, for example, acts on the hollow fiber membrane module 301, the rectangular frame-shaped support 3 is also deformed into a parallelogram. That is, the support portions 51 and 52 are swung with respect to the holding portions 41 and 42. In such a rocking motion, the arrangement portion 43 is easily deformed, and the load is easily concentrated on the base end portion 43A of the arrangement portion 43.
By providing the reinforcing member 306 in the hollow fiber membrane module 301, the swing of the support column sections 51 and 52 with respect to the holding sections 41 and 42 can be suppressed. Further, since insertion portions 46A and 46B are formed in connecting portion 30, when column portions 51 and 52 are assembled to holding portions 41 and 42, respectively, a gap can be secured between support portions 51 and 52 and wall portions 44A and 44B, and the ease of assembly can be improved, where insertion portions 46A and 46B are a space in which reinforcing member 306 is provided.
Further, since the protrusions 368 are formed in the reinforcing member 306, the filler 8 can be easily filled as described above, and the adhesiveness of the reinforcing member 306 to the column portions 51 and 52 and the wall portions 44A, 44B, 44C, and 44D can be improved. This can prevent the column parts 51 and 52 from easily swinging due to the separation of the filler 8. That is, deformation of the support 3 can be suppressed, the arrangement portion 43 and the like are not easily damaged, and durability of the hollow fiber membrane module 301 can be improved.
Further, since the reinforcing member 306 has the dividing portion 364 that extends along the ZX plane and divides the hollow portion 361, even if an external force due to the swinging of the column portions 51 and 52 is applied to the reinforcing member 306, deformation such as crushing of the hollow portion 361 is less likely to occur, and the rigidity of the reinforcing member 306 can be improved, thereby suppressing the swinging of the column portions 51 and 52.
As described above, according to the hollow fiber membrane module 301 according to the third embodiment of the present invention, the reinforcing member 306 is provided at the connection portion 30, and the durability can be improved by the reinforcing member 306. Further, the reinforcing member 306 includes: a main body 361 having a size insertable into the insertion portion 46B; and the main body 361 and the protruding portion 365 having dimensions that enable insertion into the insertion portion 46A, the reinforcing member 306 provided in the insertion portions 46A, 46B can be made common, and cost reduction can be achieved.
In addition, since the protrusions 368 are formed in the reinforcing member 306, the durability of the hollow fiber membrane module 301 can be improved.
Further, since the reinforcing member 306 has the dividing portions 364, the strength of the reinforcing member 306 is improved, and the durability of the hollow fiber membrane module 301 can be further improved.
As shown in fig. 29 to 31, the connection portions 32, 33, and 34 have the same configuration as the connection portion 31, but the connection portion 31 is different from the connection portion 32 and the connection portion 33 is different from the connection portion 34 in the configuration in which the flow path between the holding portion 41 and the support portions 51 and 52 is formed or the configuration in which the flow path between the holding portion 42 and the support portions 51 and 52 is formed. In the connection portion 31 shown in fig. 23 and 24, the portion of the groove lower portion 47B adjacent to the bottom portion 45 and the portion of the groove lower portion 47B adjacent to the bottom portion 45 communicate with each other. The placement portion 43 has a hollow portion 43C penetrating the base end portion 43A and the tip end portion 43B, the hollow portion 43C of the placement portion 43 penetrates the bottom portion 45 and communicates with the groove lower portion 47B, and the groove lower portion 47B is a flow path from the hollow fiber membrane 21.
On the other hand, as shown in fig. 29, the connecting portion 32 provided at the end 411 of the holding portion 41 connected to the suction pump is provided with a partition wall 48, and the partition wall 48 is a plate-shaped portion that partitions a portion of the groove lower portion 47B adjacent to the bottom portion 45 and a portion of the groove lower portion 47B adjacent to the bottom portion 45. Thus, the liquid filtered by the hollow fiber membranes 21 and rising in the column part 51 is directed toward the connection port 410 without flowing to the groove lower part 47B of the holding part 41 communicating with the hollow fiber membranes 21. The partition wall 48 may not be provided in the connection portion 32.
As shown in fig. 30, the connection portion 33 provided at the other end portion 412 of the holding portion 41 connected to the suction pump has the same configuration as the connection portion 31 provided at the end portion 421 of the holding portion 42. Specifically, the portion of the groove lower portion 47B adjacent to the bottom portion 45 communicates with the portion of the groove lower portion 47B adjacent to the bottom portion 45, and the hollow portion 43C of the arrangement portion 43 penetrates the bottom portion 45 to communicate with the groove lower portion 47B of the holding portion 41, and the groove lower portion 47B is a flow path from the hollow fiber membrane 21. Thus, at the end 412 of the holding part 41, the liquid filtered by the hollow fiber membranes 21 and rising through the hollow fiber membranes 21 flows from the end 411 side to the end 412 side in the groove lower part 47B of the holding part 41, and is directed toward the connection port 410. For example, the connection portion 31 and the connection portion 33 are common members that are common to each other, and the common members change the mounting position, the mounting direction to function as the connection portion 31 or the connection portion 33. The connection portion 31 and the connection portion 33 may not be common members common to each other.
As shown in fig. 31, the connection portion 34 provided at the end 422 of the lower holding portion 42 has the same configuration as the connection portion 32 provided at the end 411 of the holding portion 41. Specifically, a partition wall 48 is provided, and the partition wall 48 is a plate-like portion that partitions a portion of the groove lower portion 47B adjacent to the bottom portion 45 and a portion of the groove lower portion 47B adjacent to the bottom portion 45. Further, the connection port 410 of the end 422 of the holding portion 42 is closed by the plug 9. This prevents the liquid filtered by hollow fiber membranes 21 and descending through hollow fiber membranes 21 from flowing through groove lower 47B of holding unit 42 communicating with hollow fiber membranes 21 and flowing out from connection port 410 on the side of end 422 of holding unit 42, and prevents the liquid descending through support column 52 from flowing out from connection port 410 on the side of end 422 of holding unit 42 without flowing through groove lower 47B of holding unit 42 communicating with hollow fiber membranes 21. For example, the connection portion 32 and the connection portion 34 are common members that are common to each other, and the common members change the mounting position, mounting direction to function as the connection portion 32 or the connection portion 34. The connection portion 32 and the connection portion 34 may not be common components common to each other. The partition wall 48 may not be provided in the connection portion 34.
The present invention is not limited to the third embodiment of the present invention described above, and includes other configurations and the like that can achieve the object of the present invention, and modifications and the like shown below are also included in the present invention. In the third embodiment of the present invention described above, the insertion portion 46A and the insertion portion 46B sandwich the column portions 51, 52 in the X direction, respectively, but the insertion portion 46A and the insertion portion 46B may sandwich each of the column portions 51, 52 in the Y direction, respectively. In this case, the opening portion 49 of the insertion portion 46B is formed in the wall portion 44C or the wall portion 44D in the same manner, and the protrusion portion 65 is formed on the surface 3620C or the surface 3620D of the main body portion 361 of the reinforcing member 306 in the same manner as the opening portion 49. The reinforcing member 306 is attached to the insertion portion 46A in a posture facing away from the support portions 51 and 52 or in the same posture as the reinforcing member 306 attached to the insertion portion 46B. Even when the insertion portions 46A and 46B sandwich the column portions 51 and 52 in the X direction, the insertion portion 46B may be formed outside the insertion portion 46A. In this case, the projecting portion 65 projects to the outside of the insertion portion 46B on the opposite side to the case shown in fig. 23 described above.
In the third embodiment of the present invention described above, the wall portion 44B forming the insertion portion 46B having a small dimension in the X direction is formed to have a wall height lower than the wall portion 44A forming the insertion portion 46A having a large dimension in the X direction to form the open portion 49, but the form of the open portion 49 is not limited to this form. For example, the wall height D1 of the wall portion 44B may be made larger than the height H of the narrow portion 366 of the reinforcing member 306, and a slit-like notch or the like corresponding to the protrusion 365 may be formed in the wall portion 44B to form the open portion 49.
In the third embodiment of the present invention described above, the projecting portion 365 is formed in a plate shape, but the projecting portion may be configured to project from the main body portion, and may be, for example, a rod shape or a frame shape, and the shape thereof is not limited.
In the third embodiment of the present invention described above, the reinforcing member 306 has the wall-shaped dividing portion 364 along the insertion direction, but the dividing portion that divides the hollow portion may have other shapes as long as a force that opposes the swinging of the column portions 51 and 52 is generated. For example, the dividing portion may have a dimension in the Z direction smaller than the dimension in the Z direction of the entire reinforcing member, or the dividing portion may be formed in a rod shape extending in the X direction. The dividing portion may extend in a direction inclined to the insertion direction, or may extend in a direction orthogonal to the insertion direction. Further, the reinforcing member 306 may have a plurality of divided portions. Further, for example, in the case where the reinforcing member is difficult to deform sufficiently, such as the case where the thickness of the outer tube portion is sufficiently large, the case where the strength of the material of the reinforcing member is high, and the case where the size of the reinforcing member is small, the partitioning portion may not be formed.
In the third embodiment of the present invention described above, the reinforcing member 306 has a cylindrical shape having the hollow portion 361, but the shape of the reinforcing member of the present invention is not limited to the cylindrical shape. The reinforcing member may be formed in a bottomed cylindrical shape (cup shape) having an opening on one side (upper side or lower side) in the insertion direction, or may be formed in a block shape having no opening. In the bottomed cylindrical reinforcing member, a hollow portion may be formed in a concave shape (non-penetrating shape), and a partitioning portion may be provided to partition the hollow portion. The hollow portion or the concave portion of the reinforcing member may be filled with a filler.
In the third embodiment of the present invention described above, the placement portion 43 protrudes in a cylindrical shape and is inserted into the pillar portions 51 and 52, but the placement portion may have a shape that allows the pillar portions to be placed. For example, a groove or a recess may be formed in the bottom portion 45 to allow the column portion to be inserted, and such a groove or recess may be used as the arrangement portion. That is, the placement portion may be any portion as long as it can position the column portion. Further, the support column portion may not be provided.
In the reinforcing member, a plurality of the protrusions may be provided at intervals in the insertion direction (Z direction), and three or more protrusions may be provided on one surface. In the reinforcing member, the protrusion may extend obliquely in the insertion direction (Z direction), or may extend in a curved manner instead of extending linearly. The protrusion may extend in a direction orthogonal to the insertion direction. The reinforcing member may not have a protrusion. In this case, each surface of the outer cylinder portion is formed to be in contact with or close to the wall portion or the pillar portion of the corresponding insertion portion, similarly to the above-described protrusion portion.
In addition, two or more insertion portions 46A and 46B may be provided in all the connection portions 30 or in any one of the connection portions 30. In the case where two or more insertion portions 46A are provided, the plurality of insertion portions 46A may not all have the same size, and similarly, in the case where two or more insertion portions 46B are provided, the plurality of insertion portions 46B may not all have the same size.
In the third embodiment of the present invention described above, the reinforcing members 306 are provided in all the connection portions 30, but the reinforcing members 306 may not be provided in the connection portions 30 where the generated load is small. In addition, a connecting portion may be selectively provided in each connecting portion from among the connecting portion 30 provided with the reinforcing member 306, the connecting portion 30 provided with only one of the insertion portion 46A and the insertion portion 46B, and the connecting portion 30 not provided with the reinforcing member 306. Further, the connection unit may be selectively provided from the connection units 31, 32, 33, and 34.
While the embodiments of the present invention have been described above, the present invention is not limited to the hollow fiber membrane module according to the above-described embodiments of the present invention, and includes all embodiments included in the concept and technical means of the present invention. In addition, in order to achieve at least part of the above-described problems and effects, the respective structures may be selectively combined as appropriate. For example, the shape, material, arrangement, size, and the like of each component in the above embodiments may be appropriately changed according to a specific use mode of the present invention.
