As shown in fig. 1 to 3, a hollow fiber membrane module 1 according to a first embodiment of the present invention includes a plurality of hollow fiber membranes 21 and a support body 3 for supporting the plurality of hollow fiber membranes 21 so that the plurality of hollow fiber membranes 21 are aligned. The support body 3 has a pair of holding portions 41 and 42 and a pair of support portions 51 and 52. 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 so that the pair of holding portions 41 and 42 face each other. At least one of the holding portions 41 and 42, i.e., the holding portion 42 in fig. 3, is provided with an RFID tag 49 at least one end portion in the extending direction (X direction) of the holding portion 42, for example, on the inner side in the extending direction of the wall portion 44A of the connecting portion 31. Hereinafter, the hollow fiber membrane module 1 will be specifically described.

As shown in fig. 1 to 3, the hollow fiber membrane module 1 has a sheet-like treatment section 2, the sheet-like treatment section 2 is formed by arranging hollow fiber membranes 21 extending in an extending direction which is a predetermined direction in parallel, and the support body 3 is a frame-shaped member which surrounds the treatment section 2 and supports the treatment section 2. The ends 21A, 21B of the hollow fiber membranes 21 are held by the pair of holding parts 41, 42, respectively, and the hollow fiber membranes 21 are arranged in line along the extending direction of the holding parts 41, 42. The support sections 51, 52 extend in the extending direction of the hollow fiber membrane 21, the respective end portions 511, 512 of the support section 51 are connected to the respective one- side end portions 411, 421 of the holding sections 41, 42, and the respective end portions 521, 522 of the support section 52 are connected to the respective other- side end portions 412, 422 of the holding sections 41, 42. A connection portion 30 for connecting and fixing the column portion 51 or the column portion 52 is provided at the end portions 411, 412, 421, 422 of the holding portions 41, 42.

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 posture in use. 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 ends 21A and 21B on both sides are open, and a liquid is introduced into the hollow fiber membrane 21 through the hollow fiber membrane 21, whereby the liquid is filtered.

Fig. 4 is a diagram showing a schematic configuration of a hollow fiber membrane bundle 4 in the hollow fiber membrane module 1 according to the first embodiment of the present invention.

More specifically, the treatment section 2 is formed by arranging a plurality of hollow fiber membrane bundles 4 in parallel. As shown in fig. 4, the hollow fiber membrane bundle 4 is a member 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 rectangular tubular 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, 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 and 21B of hollow fiber membranes 21, 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 and 21B of the hollow fiber membranes 21 are not sealed, and the hollow fiber membranes 21 communicate with the outside through 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, for example, equal to or slightly larger than the dimension in the X direction of the processing unit 2, and the dimension in the Z direction in the frame of the support 3 is set to be, for example, equal to or slightly smaller than the dimension in the Z direction of the processing unit 2. That is, the hollow fiber membranes 21 may be loosely stretched between the holding portions 41 and 42.

As shown in fig. 3 and 5, the holding portions 41 and 42 have grooves 47 that are open in one direction orthogonal to the extending direction, that is, on the side where the holding portion 41 and the holding portion 42 face each other. The groove 47 extends in the extending direction of the holding portions 41, 42. As shown in fig. 3 and 5, 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 upper groove 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 upper groove 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 housed in the groove upper portions 47A of the holding portions 41 and 42 are fixed to the holding portions 41 and 42 by an adhesive. The groove lower portion 47B is sealed from the outside of the groove 47 by this adhesive. 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 7). The connection port 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 lower 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 sections 51 and 52 are formed in a tubular shape having an internal space through which liquid can pass. The support portions 51 and 52 are formed of a metal member. The pillar 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 with reference to 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. 5 and 7, a connection portion 30 is provided at an end 411 of the upper holding portion 41, a partition wall 48 that partitions a portion of the groove lower portion 47B of the holding portion 41 that communicates with the hollow fiber membrane 21 from the internal space of the support 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 that partitions a portion of the groove lower portion 47B of the holding portion 42 that communicates with the hollow fiber membrane 21 from the internal space of the support 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 of 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 membranes 21 and filtered enters the groove lower portion 47B of the lower holding portion 42 through the hollow fiber membranes 21, flows to the end 421 side in the groove lower portion 47B of the holding portion 42, then 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 hollow fiber membrane module 1 of the present embodiment, the holding sections 41 and 42 have the same configuration, and the column sections 51 and 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 column portions 51 and 52 in the support body 3 and the manner of discharge of the liquid filtered by the hollow fiber membranes 21 are not limited to the above-described configurations, 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.

Fig. 5 is a partially enlarged cross-sectional view showing the holding portion 41 and the other connection portion 32 of the column portion 51 in the hollow fiber membrane module 1 in an enlarged manner. Fig. 6 is a partially enlarged cross-sectional view showing the other connection portion 33 between the holding portion 41 and the column portion 52 in the hollow fiber membrane module 1 in an enlarged manner.

Here, the connection structure between the support 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 and 5 to 7. 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. 5, an end 411 of the upper holding portion 41 on one side in the X direction and an end 511 of the support portion 51 on the upper side are connected by a connection portion 32. As shown in fig. 6, 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. 7, 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, the connection portion 31 of the end 421 of the holding portion 42 is provided with: an arrangement portion 43 on which an end portion 512 of the pillar portion 51 is arranged; and wall portions 44A to 44D that face the pillar portion 51 disposed in the arrangement portion 43 and form a space ( gap portions 46A and 46B) adjacent to the pillar portion 51. Specifically, the connecting portion 31 is formed with an arrangement portion 43 protruding upward in the Z direction, a pair of wall portions 44A, 44B facing each other in the X direction with the arrangement portion 43 therebetween, and a pair of wall portions 44C, 44D facing each other in the Y direction with the arrangement portion 43 therebetween. 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 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 arrangement portion 43 is inserted into the opening 512A, a gap 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 gap portion 46A being a space opened to the upper side in the Z direction, and similarly, a gap 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 gap portion 46B being a space opened to the upper side in the Z direction. That is, the holding portion 42 has gap portions 46A and 46B at an end 421 in the extending direction (X 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 gap portion 46A is larger than the X-direction dimension of the inner gap portion 46B, and the Y-direction dimensions thereof are the same or substantially the same. Thus, the gap portion 46A and the gap portion 46B have different sizes from each other.

The gap portion 46A is provided with an RFID (Radio Frequency identification) tag 49 on the outside in the X direction (outside in the direction in which the hollow fiber membranes are arranged). The RFID tag 49 is attached to a place where it is difficult to be affected by interference of the support portions 51 and 52 in order to perform wireless communication with an external communication device, and the support portions 51 and 52 are metal members that cause radio wave interference. Specifically, the RFID tag 49 is provided on the outer side in the extending direction (X direction) of the holding portion of the pillar portion 51 and on the inner side in the X direction of the wall portion 44A on the outer side in the X direction out of the wall portions 44A and 44B. The RFID tag 49 is provided in the vicinity of and directly above the open end 471 which communicates the outside with the inside of the tank 47. The open end 471 is provided at one end of the tank 47 (tank lower portion 47B) that functions as a water collecting pipe on the outside in the X direction. The RFID tag 49 is provided on the inner wall portion 441 on the inner side in the X direction of the wall portion 44A disposed at a distance from the pillar portions 51 and 52 disposed in the disposition portion 43 in the vicinity of the open end portion 471.

The RFID tag 49 stores identification information of the hollow fiber membrane module 1, for example, information that can identify each hollow fiber membrane module 1, such as a product number and a lot number. The information that can be stored in the RFID tag 49 is not limited to the above example.

As described above, in the state where the RFID tag 49 is attached to the inner wall portion 441 on the inner side in the X direction of the wall portion 44A, the filler 8 is provided between the wall portions 44A, 44B and the column portions 51, 52 in the inside of the gap portions 46A, 46B. The filler 8 is, for example, a urethane adhesive, and includes a first adhesive 81, a second adhesive 82, and a third adhesive 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. 3 and 5 to 7, 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 between the sealing portion 23 and the hollow fiber membrane 21 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 to prevent the root of the hollow fiber membrane 21 from being broken or damaged by vibration.

The first adhesive 81 is more elastically deformable than the second adhesive 82, and the second adhesive 82 is harder than the first adhesive 81. Therefore, as will be described later, when the support body 3 is deformed, the deformation of each portion is easily allowed by the first adhesive 81, and the deformation of each portion is suppressed by the second adhesive 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, third adhesive 83 is easily elastically deformed similarly to first adhesive 81, and third adhesive 83 flexibly holds the root portion between hollow fiber membrane 21 and 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.

As shown in fig. 5 to 7, the connection portions 32, 33, and 34 have the same configuration as the connection portion 31, but 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, 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 connection portion 31 shown in fig. 3, the portion adjacent to the groove lower portion 47B of the bottom portion 45 and the portion adjacent to the groove lower portion 47B of 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. 5, 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. 6, 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 passes through 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 to the end 412 side through the groove lower portion 47B of the holding portion 41 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 common to each other.

As shown in fig. 7, 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 the hollow fiber membranes 21 and descending through the hollow fiber membranes 21 from flowing out from the connection ports 410 on the end 422 side of the holding part 42 through the groove lower parts 47B of the holding part 42 communicating with the hollow fiber membranes 21, and prevents the liquid descending through the support column part 52 from flowing out from the connection ports 410 on the end 422 side of the holding part 42 without flowing into the groove lower parts 47B of the holding part 42 communicating with the 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.

As described above, according to the hollow fiber membrane module 1, in the hollow fiber membrane module unit in which a plurality of hollow fiber membrane modules 1 are arranged in the stacking direction (Y direction), the RFID tag 49 is provided at least at one end 421 in the extending direction (X direction) of the holding portion 42 of the connecting portion 31. Specifically, the RFID tag 49 is provided on the inner wall 441 in the X direction of the wall 44A on the outer side in the X direction of the walls 44A and 44B. Therefore, in the hollow fiber membrane module unit in which the plurality of hollow fiber membrane modules 1 are mounted, communication with the RFID tag 49 can be easily performed from the outside in the X direction by a communication device not shown in the figure in a state in which the hollow fiber membrane modules 1 are mounted.

In addition, according to the hollow fiber membrane module 1, unlike the identification information of the imprint, the identification information can be easily acquired over a long period of time without being difficult to see due to dirt and abrasion accompanying use.

Further, according to the hollow fiber membrane module 1, since the identification information can be electronically stored by the RFID tag 49, the amount of information of the identification information can be increased.

In addition, according to the hollow fiber membrane module 1, the rfid tag 49 is provided on the inner wall portion 441 on the X-direction outer side of the column portion 51 and the X-direction inner side of the wall portion 44A in the connection portion 31, and therefore is less susceptible to interference from the metal column portion 51.

Therefore, according to the hollow fiber membrane module 1 according to the first embodiment of the present invention, the RFID tag 49 is provided on the inner wall portion 44 of the wall portion 44A on the outer side in the X direction, so that the workability at the time of inspection can be improved.

The present invention is not limited to the first embodiment described above, and includes other configurations and modifications described below that can achieve the object of the present invention. For example, in the first embodiment of the present invention described above, an example has been described in which the RFID tag 49 is provided on the wall portion 44A in the connecting portion 31 of one end 421 of the ends 421 and 422 of the holding portion 42 of the holding portions 41 and 42, but the hollow fiber membrane module 1 is not limited thereto. For example, the RFID tag 49 may be provided on the inner wall 441 of the wall 44A on the outer side in the X direction among the connecting portions 32, 33, and 34, and the connecting portions 32, 33, and 34 may be provided on the end 422 of the holding portion 42 or the ends 411 and 412 of the holding portion 41.

[ second embodiment ]

Next, a second embodiment of the present invention will be described with reference to the drawings. The same reference numerals are given to the same components or components having the same functions 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.

Fig. 8 is a partially enlarged sectional view showing a connection portion between the holding portion and the column portion in the hollow fiber membrane module 1 in an enlarged manner. Fig. 9 is another partially enlarged sectional view showing an enlarged connection portion between the holding portion and the column portion in the hollow fiber membrane module 1, and fig. 10 is a perspective view of the reinforcing member 6 of the hollow fiber membrane module 1.

As shown in fig. 1, 2, and 8, a hollow fiber membrane module 1 according to a second 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 that the plurality of hollow fiber membranes 21 are arranged. The support body 3 has a pair of holding portions 41 and 42, a pair of pillar portions 51 and 52, and at least one reinforcing member 6 and 7. The pair of holding portions 41 and 42 are members for holding the pair of ends 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 so that the pair of holding portions 41 and 42 face each other. The reinforcing members 6 and 7 are members for reinforcing the connection between the holding portions 41 and 42 and the column portions 51 and 52. Each of the holding portions 41 and 42 is provided with a connecting portion 30 formed to be connectable to the pair of column portions 51 and 52. The reinforcing members 6, 7 are provided on at least one of the connection portions 30, and the reinforcing members 6, 7 are formed so as to be inserted into the connection portion 30 and attached to the connection portion 30. At least one of the reinforcing members 6 and 7 (for example, the reinforcing member 6) is provided with an RFID tag 49 on the outer side in the extending direction of the holding portion 42. Hereinafter, the hollow fiber membrane module 1 will be specifically described.

As shown in fig. 8 and 11, the holding portions 41 and 42 have grooves 47 that are open in one direction orthogonal to the extending direction, that is, in the side where the holding portions 41 and 42 face each other. The groove 47 extends in the extending direction of the holding portions 41, 42. As shown in fig. 8 and 11, the groove 47 forms a groove upper portion 47A and a groove lower portion 47B as 2 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 of the groove 47 having an opening 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 upper groove 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 upper groove portion 47A of the groove 47 of the lower holding portion 42. A plurality of seal frames 22 are arranged and housed in the groove upper portion 47A of the holding portion 41, and a plurality of seal frames 22 are arranged and housed in the groove upper portion 47A of the holding portion 42. The plurality of seal frames 22 housed in the groove upper portions 47A of the holding portions 41, 42 are fixed to the holding portions 41, 42 by an adhesive. The groove lower portion 47B is sealed from the outside of the groove 47 by the adhesive. Thus, the groove lower portions 47B of the grooves 47 of the holding portions 41 and 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 ends 411 and 412 of the upper holding portion 41 on both sides in the X direction are connected to the suction pump by forming a connection port 410. The lower holding portion 42 has openings formed at both ends 421 and 422 in the X direction, which are the same as the connection ports 410, and is closed by the plugs 9 (see fig. 8 and 13). The connection port 410 may not be formed in the lower holding portion 42. The end portions 411 and 412 of the upper holding portion 41 may not block the groove 47 in the extending direction (X direction) by the wall portion 44A as shown, or may form the connection port 410 without forming the wall portion 44A. Similarly, the end portions 421 and 422 of the lower holding portion 42 may not block the groove 47 in the extending direction (X direction) by the wall portion 44A as shown in the figure, or may form the connection port 410 by not forming the wall portion 44A. In this case, the plug 9 has a shape following the cross-sectional shape of the groove 47. In the holding portion 41, the end 412 side is formed in the same manner as the end 411 side, and in the holding portion 42, the end 422 side is formed in the same manner as the end 421 side.

The column sections 51 and 52 have an internal space through which liquid can pass, and are formed in a tubular shape. The support portions 51 and 52 are formed of a metal member. The pillar 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 connection portion 30 as described later. In the present embodiment, as will be described later with reference to fig. 8 and 12, the connection portion 30 that enables the groove lower portion 47B of the holding portion 42 to communicate with the internal space of the column portion 51 is provided at the end portion 421 of the lower holding portion 42, and the connection portion 30 that enables the groove lower portion 47B of the holding portion 41 to communicate with 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. 11 and 13, a connection portion 30 is provided at an end 411 of the upper holding portion 41, the connection portion 30 being provided with a partition wall 48 that partitions a portion of the groove lower portion 47B of the holding portion 41 that communicates with the hollow fiber membrane 21 and an internal space of the column portion 51, and a connection portion 30 being provided at an end 422 of the lower holding portion 42, the connection portion 30 being provided with a partition wall 48 that partitions a portion of the groove lower portion 47B of the holding portion 42 that communicates with the hollow fiber membrane 21 and an internal space of the column portion 52. Thus, the support body 3 is formed with an L-shaped flow path from the bottom to the top formed by the lower holding portion 42 and the pillar portion 51, and a flow path along the upper holding portion 41. Thus, 2 independent flow paths are formed in the support body 3.

Fig. 11 is a partially enlarged cross-sectional view showing the holding portion 41 and the other connection portion 32 of the column portion 51 in the hollow fiber membrane module 1 in an enlarged manner. Fig. 12 is a partially enlarged cross-sectional view showing the other connection portion 33 between the holding portion 41 and the column portion 52 in the hollow fiber membrane module 1 in an enlarged manner. Fig. 13 is a partially enlarged cross-sectional view showing the holding portion 42 and the other connection portion 34 of the column portion 52 in the hollow fiber membrane module 1 in an enlarged manner.

Here, the detailed connection structure between the support portions 41 and 42 and the support portions 51 and 52 in the support body 3 will be described with reference to fig. 8, 9, and 11 to 13. As shown in fig. 8, an end 421 of the lower holding portion 42 on one side in the X direction and an end 512 of the support column portion 51 on the lower side are connected by the connection portion 31. As shown in fig. 11, 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. 12, 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. 13, 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. 8 and 9, the connection portion 31 of the end 421 of the holding portion 42 includes: a placement portion 43 on which an end portion 512 of the pillar portion 51 is placed; and wall portions 44A to 44D that face the pillar portion 51 disposed in the arrangement portion 43 to form a space ( gap portions 246A and 246B) adjacent to the pillar portion 51, and the reinforcing members 6 and 7 are formed to be inserted into the gap portions 246A and 246B forming the space. Specifically, the connecting portion 31 is formed with an arrangement portion 43 protruding upward in the Z direction, a pair of wall portions 44A, 44B facing each other in the X direction with the arrangement portion 43 therebetween, and a pair of wall portions 44C, 44D facing each other in the Y direction with the arrangement portion 43 therebetween. 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 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 arrangement portion 43 is inserted into the opening 512A, a gap portion 246A 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 gap portion 246A being a space opened to the upper side in the Z direction, and similarly, a gap portion 246B 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 gap portion 246B 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 gap portion 246A is larger than the X-direction dimension of the inner gap portion 246B, and the Y-direction dimensions thereof are the same or substantially the same. Thus, the gap portion 246A and the gap portion 246B have mutually different sizes. Therefore, the later-described corresponding reinforcing members 6, 7 can be prevented from being erroneously mounted.

The reinforcing members 6 and 7 are inserted into the gap portions 246A and 246B, respectively, and the reinforcing member 6 is provided in the gap portion 246A and the reinforcing member 7 is provided in the gap portion 246B. For example, the X-direction dimension of the reinforcing member 6 is larger than the X-direction dimension of the reinforcing member 7 by the difference in the X-direction dimensions of the gap portions 246A, 246B, 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 gap portion 246B.

The reinforcing member 6 has a shape corresponding to the shape of the gap portion 246A, and is fitted to the gap portion 246A in a clearance fit or an intermediate fit state. The reinforcing member 6 may be fitted to the gap portion 246A in an interference fit manner. The reinforcing member 6 has, for example, a rectangular tubular shape, and as shown in fig. 10, 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 gap portion 246A, and a rectangular tubular outer cylinder 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 gap portion 246A.

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 side. Projection 63 formed on surface 620A projects 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 pillar 51, and is formed to face the pillar 51 with a gap therebetween or to contact the pillar 51. The protrusions 63 formed on the surfaces 620C and 620D protrude toward the wall portions 44C and 44D, respectively, and are formed so as to face the wall portions 44C and 44D with a gap therebetween or so as to contact the 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 gap portion 246A (the distance between the wall portion 44A and the pillar portion 51). The Y-direction dimension of the reinforcing member 6 including the protrusion 63 is the same as or substantially the same as the Y-direction dimension of the gap portion 246A (the interval between the wall portion 44C and the wall portion 44D). Thereby, the reinforcing member 6 is fitted into the gap portion 246A as described above. The reinforcing member 6 moves in the gap portion 246A in the Z direction until contacting the bottom portion 45, and is fitted into the gap portion 246A. The dimension in the X direction and the dimension in the Y direction of the reinforcing member 6 including the projecting portion 63 are preferably smaller by about 0.1 to 3mm, more preferably about 0.5 to 2mm, respectively, than the dimension in the X direction and the dimension in the Y direction of the gap portion 246A. By setting the X-direction dimension and the Y-direction dimension of the reinforcing member 6 smaller than the corresponding dimensions of the gap portion 246A in this manner, workability when inserting the reinforcing member 6 into the gap portion 246A can be improved.

The reinforcing member 7 also has a hollow portion 71, an outer tube portion 72, a projection portion 73, and a dividing portion 74 corresponding to the hollow portion 61, the outer tube portion 62, the projection portion 63, and the dividing portion 64, respectively, as in the reinforcing member 6, and the reinforcing member 7 is fitted to the gap portion 246B in a clearance fit or an intermediate fit state. The reinforcing member 7 may be fitted to the gap portion 246B 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 projection portions 73 project 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 or contact the wall 44B, the pillar 51, the wall 44C, or the wall 44D with a gap. The reinforcing member 7 moves in the gap portion 246B in the Z direction until contacting the bottom portion 45, and is fitted into the gap portion 246B. The dimension in the X direction and the dimension in the Y direction of the reinforcing member 7 including the projecting portion 73 are preferably smaller by about 0.1 to 3mm, more preferably about 0.5 to 2mm, respectively, than the dimension in the X direction and the dimension in the Y direction of the gap portion 246B. This can improve workability when inserting the reinforcing member 7 into the gap portion 246B.

The reinforcing member 6 is provided with an RFID (Radio Frequency identification) tag 49. The RFID tag 49 is attached to a place where it is difficult to be affected by interference of the support portions 51 and 52 in order to perform wireless communication with an external communication device, and the support portions 51 and 52 are metal members that cause radio wave interference. The RFID tag 49 is provided at an end 421 of the holding portion 42 in the extending direction (X direction) on the outer side in the X direction than the pillar portion 51. Specifically, the RFID tag 49 is provided on the inner wall 621 of the plate portion 62A located on the X-direction outer side of the reinforcing member 6, which is provided on the X-direction outer side of the pillar portion 51. The RFID tag 49 is provided at one end of the groove 47 (groove lower portion 47B) on the outside in the X direction, which functions as a water collecting pipe, in the vicinity of the open end 471, which communicates the outside and the inside of the groove 47. The RFID tag 49 is provided on the inner wall 621 of the plate portion 62A in the vicinity of the open end 471, and the plate portion 62A is disposed at a distance from the support portions 51 and 52 disposed in the disposition portion 43.

As described above, in a state where the reinforcing member 6 and the reinforcing member 7 to which the RFID tag 49 is attached are fitted into the gap portions 246A, 246B, 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, for example, a urethane adhesive, and includes a first adhesive 81, a second adhesive 82, and a third adhesive 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. 8 and 11 to 13, the second adhesive 82 serves as the sealing portion 23 of the hollow fiber membrane bundle 4, and the groove upper portion 47A for filling the groove 47, and the third adhesive 83 adheres to the root portion between the hollow fiber membrane 21 and the sealing portion 23. The third adhesive 83 is attached to protect the hollow fiber membrane 21 and to prevent the root of the hollow fiber membrane 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 will be described later, when the support body 3 is deformed, the deformation of each portion is easily allowed by the first adhesive 81, and the deformation of each portion is suppressed by the second adhesive 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, third adhesive 83 is easily elastically deformed similarly to first adhesive 81, and third adhesive 83 flexibly holds the root portion between hollow fiber membrane 21 and 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 protrusions 63 and 73 in this way, it is easier to fill the filler 8 around the reinforcing members 6 and 7 inserted into the gaps 246A and 246B, 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 on the sides of the holding portions 41 and 42 facing the respective surfaces of the reinforcing members 6 and 7, and therefore, the gap interval around the reinforcing members 6 and 7 can be kept constant 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 rocking of the column parts 51 and 52 with respect to the holding parts 41 and 42 can be suppressed. Further, since the gap portions 246A and 246B, which are spaces in which the reinforcing members 6 and 7 are provided, 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.

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 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 1 can be improved.

Further, since the reinforcing members 6 and 7 have the dividing portions 64 and 74 extending along the ZX plane and dividing the hollow portions 61 and 71, respectively, even if an external force generated by the swinging of the column portions 51 and 52 is applied to the reinforcing members 6 and 7, the hollow portions 61 and 71 are less likely to be deformed such as crushed, and the rigidity of the reinforcing members 6 and 7 can be increased, thereby suppressing the swinging of the column portions 51 and 52.

As described above, according to the hollow fiber membrane module 1 according to 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, 7 have the dividing portions 64, 74, the strength of the reinforcing members 6, 7 can be improved, and the durability of the hollow fiber membrane module 1 can be further improved.

As shown in fig. 11 to 13, 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 paths between the holding portion 41 and the support portions 51 and 52 are formed or the configuration in which the flow paths between the holding portion 42 and the support portions 51 and 52 are formed. In the connection portion 31 shown in fig. 8 and 9 described above, the portion adjacent to the groove lower portion 47B of the bottom portion 45 and the portion adjacent to the groove lower portion 47B of 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. 10, 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. 12, 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 passes through 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 to the end 412 side through the groove lower portion 47B of the holding portion 41 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 common to each other.

As shown in fig. 13, 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 the hollow fiber membranes 21 and descending through the hollow fiber membranes 21 from flowing out from the connection port 410 on the end 422 side of the holding portion 42 through the groove lower portion 47B of the holding portion 42 communicating with the hollow fiber membranes 21, and prevents the liquid descending through the support column portion 52 from flowing out from the connection port 410 on the end 422 side of the holding portion 42 without flowing into the groove lower portion 47B of the holding portion 42 communicating with the 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, the 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.

As described above, according to the hollow fiber membrane module 1, in the hollow fiber membrane module unit in which a plurality of hollow fiber membrane modules 1 are arranged in the stacking direction (Y direction), the RFID tag 49 is provided at least at one end 421 in the extending direction (X direction) of the holding portion 42 of the connecting portion 31. Specifically, the RFID tag 49 is provided on the inner wall 621 of the X-direction outer plate portion 62A of the reinforcing member 6. Therefore, in the hollow fiber membrane module unit in which the plurality of hollow fiber membrane modules 1 are mounted, communication with the RFID tag 49 can be easily performed from the outside in the X direction by a communication device not shown in the figure in a state in which the hollow fiber membrane modules 1 are mounted.

According to the hollow fiber membrane module 1, the RFID tag 49 is attached to the inner wall 621 of the plate portion 62A of the reinforcing member 6. On the other hand, the filler 8 is provided with the reinforcing members 6 and 7 on which the protrusions 63 and 73 are formed, and the filler 8 is easily filled into the gap between the reinforcing member 6 and the inner wall portion 44. Therefore, according to the hollow fiber membrane module 1, by providing the reinforcing members 6 and 7, even if the RFID tag 49 is attached, it is possible to prevent the adhesive strength between the reinforcing members 6 and 7 and the inner wall portion 44 from being reduced.

In addition, according to the hollow fiber membrane module 1, unlike the identification information of the imprint, the identification information can be easily acquired over a long period of time without being difficult to see due to dirt and abrasion accompanying use.

Further, according to the hollow fiber membrane module 1, since the identification information can be electronically stored by the RFID tag 49, the amount of information of the identification information can be increased.

In addition, according to the hollow fiber membrane module 1, the rfid tag 49 is provided on the inner wall 621 of the plate portion 62A on the outer side in the X direction of the column portion 51 in the connection portion 31, and therefore is less susceptible to interference from the metal column portion 51.

Therefore, according to the hollow fiber membrane module 1 according to the embodiment of the present invention, the workability at the time of inspection can be improved by providing the RFID tag 49 on the inner wall 621 of the X-direction outer plate portion 62A of the reinforcing member 6.

The present invention is not limited to the above-described embodiments, and modifications and the like described below including other configurations and the like that can achieve the object of the present invention are also included in the present invention. For example, in the above-described embodiment of the present invention, an example in which the RFID tag 49 is attached to the plate portion 62A in the reinforcing member 6 provided at one end 421 of the end 421 and 422 of the holding portion 42 of the holding portions 41 and 42 has been described, but the hollow fiber membrane module 1 is not limited thereto. For example, the RFID tag 49 may be attached to the inner wall 621 of the X-direction outer plate portion 62A of the connection portions 32, 33, and 34, the connection portions 32, 33, and 34 being provided at the end 422 of the holding portion 42 or the ends 411 and 412 of the holding portion 41.

For example, in the above-described embodiment of the present invention, the reinforcing members 6 and 7 have the wall- like partitioning portions 64 and 74 along the insertion direction, but the partitioning portions partitioning 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, when the reinforcing member is difficult to deform sufficiently, such as when the outer tube portion is thick enough, when the strength of the material of the reinforcing member is high, or when the size of the reinforcing member is small, the dividing portion may not be formed.

As a modification, as shown in fig. 14, instead of forming the dividing portions, a plurality of reinforcing members may be inserted into the respective gap portions 246A and 246B. For example, a plurality of reinforcing members 10 may be arranged in the gap portion 246A in the Y direction, or a plurality of reinforcing members 11 may be arranged in the gap portion 246B in the Y direction. In the illustrated example, two reinforcing members 10 are provided in the gap portion 246A in the Y direction, and a plurality of reinforcing members 11 are provided in the gap portion 246B in the Y direction. The reinforcing members 10 and 11 have hollow portions 101 and 111 and outer tubular portions 102 and 112, and have protrusions 103 and 113 formed on the outer tubular portions 102 and 112, and no dividing portions, as in the reinforcing members 6 and 7. 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 way, 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 compared to a structure in which only one reinforcing member is provided, and the rigidity of the reinforcing member 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 above-described embodiment of the present invention may be arranged in the Y direction, and according to such a configuration, the durability of the hollow fiber membrane module can be further improved.

In the above-described embodiment of the present invention, the gap portion 246A and the gap portion 246B sandwich the column portions 51 and 52 in the X direction, respectively, but the gap portion 246A and the gap portion 246B may sandwich the column portions 51 and 52 in the Y direction, respectively.

In the above-described embodiment of the present invention, the reinforcing members 6 and 7 have a cylindrical shape having the hollow portions 61 and 71, but the shape of the reinforcing member according to 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. The hollow portion or the concave portion of the reinforcing member may be filled with a filler.

In the above-described embodiment of the present invention, the placement portion 43 protrudes in a cylindrical shape and is inserted into the column portions 51 and 52, but the placement portion may have a shape that allows the column 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.

As shown in fig. 15, in the reinforcing member 6, a plurality of the protrusions 63 may be provided at intervals in the insertion direction (Z direction), or three or more protrusions 63 may be provided on one surface. 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 gap portions 246A and 246B may be provided in all the connection portions 30 or 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 column portions 51 and 52 connected to the connection portion 30 with a gap therebetween, and only either one of the gap portion 246A and the gap portion 246B may be formed in the connection portion 30.

In the above-described embodiment, the reinforcing members 6 and 7 or the reinforcing members 10 and 11 are provided in all the connection portions 30, but the reinforcing members 6 and 7 or the reinforcing members 10 and 11 may not be provided in the connection 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 gap portions 246A and 246B, 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 connection 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.

In general, a plurality of hollow fiber membrane modules 1 are arranged in a row in the hollow fiber membrane module unit. Therefore, when the information of the RFID tag 49 is read from the outside of the support body 3 of the hollow fiber membrane module 1, the RFID tag 49 attached to the gap portion 246A is less susceptible to the influence of the pillar portion than the gap portion 246B. Therefore, in the hollow fiber membrane module 1 used in the above-described mode, the RFID tag 49 is preferably provided in the hollow portion of the reinforcing members 6 and 7 in the gap portion 246A as compared with the gap portion 246B.

[ third embodiment ]

Next, a third embodiment of the present invention will be described with reference to the drawings. The same reference numerals are used for the same members or members having the same functions as those of the hollow fiber membrane module 1 according to the first and second embodiments of the present invention, and the description thereof will be omitted.

As shown in fig. 1, 2, and 16, a hollow fiber membrane module 1 according to an 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 that the plurality of hollow fiber membranes 21 are aligned. The support body 3 includes a pair of holding portions 41 and 42 and a pair of support portions 51 and 52. 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 so that the pair of holding portions 41 and 42 face each other. At least one of the holding portions 41 and 42, for example, the holding portion 42 includes: a tank 47 through which liquid can pass; an opening 423 formed at the ends 411, 421 of the holding portions 41, 42 and communicating with the groove 47; and a plug 9 closing the opening portion 423. An RFID tag 49 is provided on the plug 9. Hereinafter, the hollow fiber membrane module 1 will be specifically described.

The ends 411 and 412 of the upper holding portion 41 on both sides in the X direction are connected to the suction pump by forming a connection port 410. An opening 423 communicating with the groove 47 is formed as an opening similar to the connection port 410 in both ends 421, 422 of the lower holding portion 42 in the X direction, and the opening 423 is closed by providing a plug 9 (see fig. 13, 16). The plug 9 is formed in a cylindrical shape having a bottom corresponding to the shape and size of the opening 423, for example, so as to close the opening 423. The connection port 410 may not be formed in the lower holding portion 42. The end portions 411 and 412 of the upper holding portion 41 may not block the groove 47 in the extending direction (X direction) by the wall portion 44A as shown in the figure, or may form the connection port 410 without forming the wall portion 44A. Similarly, the end portions 421 and 422 of the lower holding portion 42 may not block the groove 47 in the extending direction (X direction) by the wall portion 44A as shown in the figure, or may form the connection port 410 by not forming the wall portion 44A. In this case, the plug 9 has a shape following the cross-sectional shape of the groove 47. 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.

An RFID (Radio Frequency IDentifier) tag 49 is provided to the plug 9. Specifically, the RFID tag 49 is provided on the inner wall 91 of the plug 9 formed in a bottomed cylindrical body in the X direction (inside the holding portion 42 in the extending direction and inside the hollow fiber membranes in the direction of arranging the hollow fiber membranes in parallel). In order to perform wireless communication with an external communication device, the RFID tag 49 is separated from the pillar portion 51, which is a metal member that causes radio wave interference, and is attached to a place where it is difficult to be affected by the interference of the pillar portion 51. The RFID tag 49 is sealed by a third adhesive 83 filled in the inside of the plug 9. The third adhesive 83 prevents the RFID tag 49 from peeling off from the inner wall portion 91. The rfid tag 49 is securely fixed to the inner wall 91 of the plug 9 by the third adhesive 83.

As described above, according to the hollow fiber membrane module 1, in the hollow fiber membrane module unit in which a plurality of hollow fiber membrane modules 1 are arranged in the stacking direction (Y direction), the RFID tag 49 is provided at least at one end portion 421 in the extending direction (X direction) of the holding portion 42 of the connection portion 31. Specifically, the RFID tag 49 is provided on the inner wall 91 of the plug 9, and the plug 9 closes the opening 423 communicating with the groove 47 through which liquid can pass. Therefore, in the hollow fiber membrane module unit in which the plurality of hollow fiber membrane modules 1 are mounted, communication with the RFID tag 49 can be easily performed from the outside in the X direction by a communication device not shown in the figure in a state in which the hollow fiber membrane modules 1 are mounted.

In addition, according to the hollow fiber membrane module 1, since the plug 9 is provided separately from the column section 51, which is a metal member, it is less susceptible to radio interference from the column section 51.

Further, according to the hollow fiber membrane module 1, the RFID tag 49 is provided on the plug 9 detachably attached to the open end 471. Therefore, the RFID tag 49 can be attached to the completed hollow fiber membrane module 1 by a simple operation of replacing the plug 9.

In addition, according to the hollow fiber membrane module 1, unlike the identification information of the imprint, the identification information can be easily acquired over a long period of time without being difficult to see due to dirt and abrasion accompanying use.

Further, according to the hollow fiber membrane module 1, since the identification information can be electronically stored by the RFID tag 49, the amount of information of the identification information can be increased.

Therefore, according to the hollow fiber membrane module 1 according to the embodiment of the present invention, the workability at the time of inspection can be improved by providing the RFID tag 49 to the plug 9.

The present invention is not limited to the above-described embodiments, and includes other configurations and modifications as described below, which can achieve the object of the present invention. For example, in the above-described embodiment of the present invention, an example in which the RFID tag 49 is attached to the inner wall portion 91 of the plug 9 provided at one end portion 421 of the end portions 421 and 422 of the holding portion 42 of the holding portions 41 and 42 has been described, but the hollow fiber membrane module 1 is not limited thereto. For example, the RFID tag 49 may be attached to the plug 9 provided at the end 422 of the holding portion 42.

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 of the present invention and the claims. 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 can be appropriately changed according to a specific use mode of the present invention.
