Description

  The present invention relates to an in-pipe purification device and an in-pipe purification system. More specifically, the present invention relates to an in-pipe purification device having deformation resistance and an in-pipe purification system using the same.

  Conventionally, sewage is transferred to a sewage treatment facility through a pipeline, and all sewage purification processing is performed at the sewage treatment facility. Therefore, in the sewage treatment facility, the equipment cost or equipment space accompanying the purification equipment is required.

  Therefore, in order to reduce the burden on the sewage treatment facility, a method for purifying sewage in the pipeline using microorganisms has been proposed. For example, International Publication No. 2013/172288 (Patent Document 1) has a double tube structure composed of an outer tube wall and a water permeable inner tube, and a microorganism carrier in the gap between the double tube structures. Is disclosed.

International Publication No. 2013/172288 Pamphlet

  In the above-described purification apparatus for pipe tubs, a cuboid foam piece is used as the microbial carrier, and the microbial carrier is filled in a space in the water purification section in a free state or in a state of being accommodated in a small-diameter pipe. Is done.

  In order to prevent clogging in the pipeline (specifically, clogging due to retention of foreign matter or the like in the drainage), the present inventors have set the pipeline so that the microbial carrier does not move as an accommodation mode of the microbial carrier. We focused on fixing to the internal purification device. In order to fix the microorganism carrier to the in-pipe purification apparatus, the working space for fixing the carrier can be secured by cutting out the entire lowermost part of the apparatus along the extending direction. However, if the lowermost part of the device is cut out and deleted, the width of the deleted part will be narrowed when a large load is applied vertically downward due to excessive drainage or excessive foreign matter flow, resulting in a pipe line The inner purification device tends to be greatly deformed downward. Further, even in a normal drainage state, it can be similarly deformed vertically downward by creep or the like during long-term use. When the in-pipe purification device is deformed in this way, the space area of the purification unit is narrowed, and foreign matter is likely to be clogged.

  Accordingly, an object of the present invention is to provide an in-pipe purification apparatus that is difficult to cause clogging in the pipe line and is resistant to deformation.

In order to achieve the above object of the present invention, the present invention includes the following inventions.
(1)
The in-pipe purification apparatus of the present invention should be installed in a pipe. The in-pipe purification apparatus includes a separator, a spacer, and a carrier for supporting microorganisms.
The separator includes a support part and a partition part. The support part has a surface along the lower inner wall surface of the pipe line, and a deletion part is provided along the axial direction of the pipe line. The partition part partitions the inside of the pipe and has a hole.
The spacer includes a closing portion that closes the deletion portion in at least a part of the axial direction.
The carrier is fixed inside the separator.

  In the above configuration, since the carrier is fixed inside the separator, clogging in the pipeline is less likely to occur, and the missing portion in the support portion of the separator is blocked by the spacer, so that the width of the missing portion is maintained. The deformation of the separator can be prevented by sagging.

(2)
The spacer may include a holding unit that holds the carrier.
In this case, the spacer for preventing deformation can also have a carrier fixing function.

(3)
The in-pipe purification apparatus may include a plurality of separators, and the spacer may include a joint portion that connects the plurality of separators to each other.
In this case, the spacer for preventing deformation can also have a separator connecting function.

(4)
The spacer may include a fixed surface that contacts the outer surface of the support portion of the separator.
In this case, the spacer can be stably fixed to the separator by grounding the fixing surface to the outer surface. Therefore, it is possible to stably prevent the separator from being deformed.

(5)
The spacer may include a fixed surface that contacts an inner surface of the support portion of the separator.
In this case, the spacer can be stably fixed to the separator by grounding the fixing surface to the inner side surface. Therefore, it is possible to stably prevent the separator from being deformed. Furthermore, since the spacer is fixed inside the separator, the lower outside of the in-pipe purification device is structurally simple, and the installation stability on the inner wall of the pipe is excellent.

(6)
The in-pipe purification system according to the present invention includes a pipe and the in-pipe purification device according to (1) to (5) installed in the pipe so as to extend in an axial direction of the pipe. And including.

  In this case, the carrier is fixed inside the separator, so that clogging in the pipeline is less likely to occur, and the missing part in the support part of the separator is blocked by the spacer, and the width of the missing part is maintained. As a result, the deformation of the separator can be prevented.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description, the same elements are denoted by the same reference numerals, and their names and functions are also the same. Therefore, detailed description thereof will not be repeated basically.

[First Embodiment]
FIG. 1 is a partially cutaway view schematically showing an in-pipe purification system using the in-pipe purification device of the first embodiment. FIG. 2 is a schematic external perspective view of the in-pipe purification device (part) of FIG. FIG. 3 is an exploded perspective view of the in-pipe purification device (part) of FIG. FIG. 4 is a schematic cross-sectional view when cut along a plane including the IV-IV line in FIG. 2. FIG. 5 is an enlarged view of a main part of FIG. In the following, for the sake of convenience, the upward direction in FIG. 4 will be described as being upward, and the downward direction being downward. These directions substantially coincide with the absolute direction when the in-pipe purification apparatus is used, but do not necessarily mean the absolute direction when the in-pipe purification apparatus is manufactured. Moreover, the part corresponded in the right-and-left end part of the purification apparatus in a pipe line in FIG. 4 may be described as a both side part.

[Basic configuration]
An in-pipe purification system 900 shown in FIG. 1 includes a pipe 910 and an in-pipe purification device 100 provided in the pipe 910. As shown in FIGS. 2 to 4, the separator 200, the carrier fixing member 300, the carrier 400 that should carry the microorganisms, and the spacer 600 are included. The carrier fixing member 300 is not essential.

[Separator]
The separator 200 is a long body having a certain cross-sectional shape that extends in the axial direction of the pipe 910 (see FIG. 1). The length of the separator 200 in the axial direction corresponds to the length of the conduit 910. (In FIGS. 2 and 3, a part of the elongated body is shown for convenience.) As shown in FIGS. 2 and 4, the separator 200 includes a support part 210 and a partition part 250. The The support part 210 and the partition part 250 are joined at both side edges (that is, left and right side edges). As shown in FIG. 4, the support part 210 and the partition part 250 are integrally formed. As shown in FIG. 4, the cross-sectional shape of the separator 200 is axisymmetric with respect to a straight line passing through the axis O of the pipe 910 and the lowest point of the pipe 910.

  As shown in FIG. 4, the support portion 210 has a concave curved surface 211 inside the separator 200 and a convex curved surface 212 outside the separator 200. Both the concave curved surface 211 and the convex curved surface 212 have a circular arc shape in cross section, and form a curved plate shape. The concave curved surface 211 is fixed via a carrier fixing member 300 (described later). The convex curved surface 212 is along a part of the inner wall surface of the pipe 910. Thereby, the separator 200 can be installed along the lower inner wall surface of the pipe line 910. Furthermore, the support part 210 has the deletion part 215 by which the vicinity of the lowest point of the pipe line 910 was notched. The deletion portion 215 is formed over the entire extending direction of the separator 200 (the axial direction of the conduit 910). As a result, the carrier 400 can be disposed from the missing portion 215 to the inside of the separator 200, so that the carrier 400 is easily disposed.

  The partition part 250 is a deformed plate-like perforated member in which water-permeable holes 254 (described later) are formed. As shown in FIG. 4, when the partition purification unit 100 is provided in the pipeline 910 by spanning between both side edges of the support unit 210, the partition 250 is provided in the pipeline 910. This space is divided into a lower purification unit 911 and an upper flow rate securing unit 915. The partition part 250 is configured in a shape in which the center part (that is, the part on the target axis) is lower than the left and right side parts. In this embodiment, the partition part 250 has the flow velocity securing part 251 on the symmetry axis, and the pair of plane parts 253 and the pair of inclined parts 255 are arranged in this order from the side closer to the symmetry axis to the far side. It is formed with. The pair of flat portions 253 and the pair of inclined portions 255 are respectively arranged in parallel with the extending direction of the separator 200.

  As shown in FIG. 4, the flow velocity securing part 251 constituting the lowest part of the central part of the partition part 250 constitutes the lowest part of the central part of the partition part 250, and its cross-sectional shape is convex downward. Is curved. With such a curved shape, a flow rate during a small amount of drainage in the pipeline is ensured.

  As shown in FIG. 4, a water-permeable hole 254 is formed in the flat portion 253. The water permeable hole 254 discharges the drainage to the purification unit 911 when the drainage in the flow rate securing unit 915 exceeds the capacity of the flow rate securing unit 251. A plurality of water permeable holes 254 are provided along the extending direction of the separator 200 (see FIG. 1). This imparts water permeability to the separator 200. In addition, since the flat portion 253 is flat in the horizontal direction, the workability of drilling the water permeable holes 254 is good during manufacturing.

  As shown in FIG. 4, the inclined portion 255 is formed so as to rise from the flat portion 253 toward the inner wall of the duct 910 and gradually rise along the inner wall surface. Thereby, it is easy to guide the waste water in the flow rate securing unit 915 to the purification unit 911, and it is easy to prevent clogging between the partition unit 250 and the inner wall of the pipe line 910. In the present embodiment, the shape of the inclined portion 255 is flat, but a curved shape that continues smoothly from the flat portion 253 so as to protrude downward from the flat surface of the inclined portion 255 shown in FIG. It may have a curved slope.

  When the support part 210 and the partition part 250 are configured as described above, the separator 200 is disposed below the center of the internal space of the pipe line 910 when provided in the pipe line 910 as shown in FIG. It is formed to occupy a part of the side. That is, the uppermost point of the separator 200 is formed so as to be positioned below the horizontal position of the axis O of the pipe 910 with a drop E therebetween. By separating the head E, installation in the pipe 910 is facilitated.

Separator 200 can be made of resin. Examples of the resin include thermoplastic resins such as vinyl chloride resins and olefin resins, and thermosetting resins such as epoxy resins and unsaturated polyester resins. The resin may be in the form of a composite material, that is, FRP (fiber reinforced plastic) reinforced with a fiber material such as glass fiber or carbon fiber.
For manufacturing the separator 200, a manufacturing method corresponding to the type of resin is selected. For example, in the case of a thermoplastic resin, it can be manufactured by extrusion molding. In this case, it can be manufactured by extrusion molding using a mold whose outlet shape is the same as the cross-sectional shape of the separator 200. In addition, for example, the exit shape is manufactured by extruding using a mold having a closed cross section composed of the support part 210 having no deletion part 215 and the partition part 250, and then forming the deletion part 215 by notching. Alternatively, extrusion may be performed using a mold having an annular outlet shape, and thereafter, forming into a closed cross-sectional shape constituted by the support part 210 and the partition part 250 without the deletion part 215 will be performed. You may manufacture by performing notch formation. For example, in the case of a thermosetting resin and FRP, it can be manufactured by a hand lay-up method, a pultrusion molding method, or the like.

  In addition, the shape of the partition part 250 is not limited to that shown in the drawings, and may be a shape that spans between both side edges of the support part 210, preferably a shape that is lowest at the center part.

[Carrier fixing member]
As shown in FIGS. 2 to 4, the carrier fixing member 300 is fixed to the concave curved surface 211 of the support portion 210 constituting the separator 200. In the present embodiment, as shown in FIG. 5, the carrier fixing member 300 includes a holding part 310 and a fixing part 320 that are integrally formed.

  As shown in FIG. 5, the holding part 310 and the fixing part 320 are formed so as to constitute a deformed rectangular closed cross section. The holding part 310 holds the outer surface of the carrier 400 (in the present embodiment, the upper surface and both the left and right side surfaces) so as to cover it. The fixing portion 320 is provided below the holding portion 310 and has a fixed curved surface 321 that covers the entire lower surface of the carrier 400 and has a shape along the concave curved surface 211 of the separator 200. With such a closed cross-sectional structure, the carrier 400 is held from the direction of the entire outer surface thereof, so that stable holding is possible.

  The carrier fixing member 300 is fixed at a position where the height N (see FIG. 4) of the narrowest portion in the purification unit 911 space can be secured. Ensuring the height N of the narrowest part in the purification part 911 space is preferable from the viewpoint of preventing clogging between the carrier fixing member 300 and the partition part 250.

The depth of the holding portion 310 (length in the extending direction of the separator 200) is appropriately set from the viewpoint of favorably holding the carrier 400, securing the exposed portion of the surface of the carrier 400, and the like. In the present embodiment, the depth is constituted by 4% of the diameter of the inner periphery of the pipe 910.
The carrier fixing member 300 may have the same depth throughout.

  As shown in FIG. 5, the fixed curved surface 321 has a shape along the concave curved surface 211 of the support portion 210 of the separator 200 and is fixed in contact with the concave curved surface 211. By providing the fixed curved surface 321, a sufficient contact area with the concave curved surface 211 can be secured. The fixed curved surface 321 is fixed between the surface of the separator 200 via an adhesive.

  In the axial direction of the pipe line 910, the location and interval at which the carrier fixing member 300 is provided are not particularly limited. For example, with respect to one pipe line 910, you may provide in two places of the axial direction both ends, three places of the said both ends and center part, or more places.

  The carrier fixing member 300 can be made of resin. Examples of the resin include thermoplastic resins such as vinyl chloride resins and olefin resins, and thermosetting resins such as epoxy resins and unsaturated polyester resins. The resin may be in the form of a composite material, that is, FRP (fiber reinforced plastic) reinforced with a fiber material such as glass fiber or carbon fiber. The carrier fixing member 300 may be made of the same material as the separator 200 or may be different. The carrier fixing member 300 can be manufactured by injection molding. In the case of FRP, it can be produced by a hand lay-up method, a resin transfer molding (RTM) method, or the like.

  The carrier fixing member 300 is fixed to the support portion 210 of the separator 200 by using an adhesive between the fixed curved surface 321 and the concave curved surface 211. The adhesive can be appropriately determined by those skilled in the art in consideration of the material of the support portion 210 and the material of the carrier fixing member 300. For example, a rubber adhesive mainly composed of styrene-butadiene, a solvent-based adhesive, and the like can be given.

[Carrier]
As shown in FIGS. 1 and 3, the carrier 400 is a wide and long body extending in the axial direction of the pipe 910. The length of the carrier 400 in the axial direction corresponds to the length of the conduit 910. As the carrier 400, a structure having a large specific surface area is used without particular limitation. For example, a porous material (for example, an inorganic porous body, an inorganic foam, a resin foam, etc.), a fibrous material (for example, a woven fabric, a nonwoven fabric, a single fiber body, a net-like body, etc.), a layered material (for example, a sheet laminate) Etc.). The fine pores of the porous material are preferably continuous pores. In the present embodiment, a resin foam is used. Examples of the resin include olefin resins (particularly polyethylene), urethane resins, vinyl chloride resins, acrylic resins, and the like.

  The shape of the carrier 400 may be any shape that can be held by the carrier fixing member 300, and is a long body having a rectangular cross section in the present embodiment. In this embodiment, since the carrier 400 is a foam resin, the size of the cross-sectional shape of the carrier 400 may be designed to be slightly larger than the inside of the holding portion 310 of the carrier fixing member 300. In this case, when the carrier 400 is held by the holding portion 310 of the carrier fixing member, the carrier 400 is contracted and deformed in the bending holding portion 310, so that the carrier 400 is stably held by the holding portion 310. In addition, it can fix more stably by interposing an adhesive agent between the carrier 400 and the carrier fixing member 300.

  For example, after the carrier 400 is deformed and set so as to be screwed into the inside of the carrier fixing member 300, the carrier curved surface 321 of the carrier fixing member 300 is grounded to the concave curved surface 211 of the support portion 210, thereby fixing the carrier. It can be stably fixed to the support part 210 via the member 300. In the present embodiment, it is possible to fix more stably by using an adhesive between the carrier 400 and the support part 210 at the place where the carrier fixing member 300 is provided. Further, it may be more stably fixed by using an adhesive between the carrier 400 and the support part 210 at a place where the carrier fixing member 300 is not provided.

  The size of the carrier 400 in the conduit 910 (width w and height h in FIG. 4) is determined in consideration of the purification efficiency and the size allowed for the carrier fixing member 300 in the purification unit 911. be able to. In the present embodiment, the width w is 10% of the inner peripheral length of the conduit 910, and the height h is 2% of the inner peripheral length of the conduit 910.

  As shown in FIG. 4, in the pipe 910, the carrier 400 is disposed so as to face the surface connecting the axis O and the lowest position of the pipe 910. The arrangement position of the carrier 400 in the pipe line 910 can be determined in consideration of the purification efficiency and the like. For example, the separation distance i of the carrier 400 may be disposed so as to be 10% or more and 40% or less of the inner circumference of the pipe 910. The separation distance i being equal to or greater than the lower limit is that the flow rate in the purification unit 911 is ensured even when the water level of the purification unit 911 is low, the carrier 400 is brought into contact with air, and clogging is prevented. From the viewpoint of obtaining good purification efficiency, the carrier 400 is effectively brought into contact with the waste water when the water level rises.

[Spacer]
As shown in FIG. 2 and FIG. 4, the spacer 600 is provided in the deletion portion 215 formed in the support portion 210 of the separator 200. As shown in FIGS. 3 and 5, the spacer 600 includes a blocking portion 610 and a fixing portion 620. The blocking part 610 has a curved plate shape along the inner wall surface of the conduit 910 and has contact surfaces 615 on both left and right ends. The contact surface 615 closes the deletion portion 215 by contacting the surface of the deletion portion 215 (see FIG. 5). As a result, even if a load is applied in the vertically downward direction, the width of the deletion portion 215 is maintained without narrowing. In addition, the part which the obstruction | occlusion part 610 obstruct | occludes the deletion part 215 is a part of extension direction (axial direction of the pipe line 910) of the separator 200, as shown in FIG. By providing such spacers 600 at a plurality of locations in the direction, the width of the deletion portion 215 is stably maintained.

  As shown in FIGS. 3 and 5, the fixing portion 620 is provided to extend on both sides of the closing portion 610 and has a curved plate shape along the inner wall surface of the pipe 910. The fixed portion 620 has a fixed curved surface 622 that contacts the convex curved surface 212 of the support portion 210 of the separator 200. When the fixed curved surface 622 contacts the convex curved surface 212, the spacer 600 is stably fixed to the separator 200. An adhesive may be interposed between the convex curved surface 212 and the fixed curved surface 622.

  The spacer 600 can be made of resin. Examples of the resin include thermoplastic resins such as vinyl chloride resins and olefin resins, and thermosetting resins such as epoxy resins and unsaturated polyester resins. The resin may be in the form of a composite material, that is, FRP (fiber reinforced plastic) reinforced with a fiber material such as glass fiber or carbon fiber. The spacer 600 may be made of the same material as that of the separator 200 or may be different. The spacer 600 can be manufactured by injection molding. In the case of FRP, it can be produced by a hand lay-up method, a resin transfer molding (RTM) method, or the like.

[Manufacture of pipe purification equipment]
After the separator 200 is manufactured, the in-pipe purification device 100 fixes the carrier 400 in the separator 200 from the deletion part 215 via the carrier fixing member 300, and then closes the deletion part 215 with the spacer 600. To manufacture.

  The manufactured in-pipe purification apparatus 100 is installed in the pipe 910 (see FIG. 1), thereby constituting an in-pipe purification system 900. Since the concave curved surface 211 of the support part 210 is shielded by the partition part 250, the duct 910 space is partitioned into a lower purification part 911 and an upper flow rate securing part 915.

  When the in-pipe purification system 900 is started, drainage is caused to flow through the pipe 910 and the drainage is brought into contact with the carrier 400 in the purification unit 911. As a result, a biofilm is formed on the surface of the carrier 400. Since the carrier 400 has a large specific surface area as described above, a biofilm can be formed efficiently. When the biofilm comes into contact with the wastewater, useful microorganisms in the biofilm purify the wastewater. Further, when the drainage level in the purification unit 911 is raised and lowered, the biofilm attached to the carrier 400 can be brought into contact with air as well as being immersed in the wastewater. Therefore, aerobic microorganisms that are useful microorganisms can also be effectively propagated.

[Other Embodiments]
Hereinafter, a second embodiment in which the shape of the blocking portion of the spacer is different, a third embodiment in which the spacer is integrated with the carrier fixing member, a fourth embodiment in which the spacer fixing mode is different, and a fifth embodiment further including a separator fixing member. An embodiment and a sixth embodiment in which the spacer is integrated with the joint will be described. In these embodiments, differences from the first embodiment will be mainly described, and description of the same points will be omitted.

[Second Embodiment]
FIG. 6 is an exploded perspective view of the in-pipe purification apparatus of the second embodiment, and corresponds to FIG. 3 of the first embodiment. The in-pipe purification apparatus 100a shown in FIG. 6 is the same as the in-pipe purification apparatus 100 of the first embodiment except that it includes a spacer 600a.

  The spacer 600a includes a closing part 610a and a fixing part 620a. The blocking portion 610a has contact surfaces 615a on both side ends, and contacts the deletion portion 215 so that the deletion portion 215 extends over the entire extending direction of the separator 200 (the axial direction of the conduit 910). Block. Since the separator 200 and the spacer 600a are formed to have the same length, the width of the deletion portion 215 is stably maintained.

A fixing portion 620a extending from both sides of the closing portion 610a is also formed over the entire direction. For this reason, a large contact area between the fixed curved surface 622a of the fixing portion 620a and the convex curved surface 212 of the separator 200 can be secured, and the separator 200 is more stably fixed.

[Third Embodiment]
FIG. 7 is a schematic external perspective view of the in-pipe purification apparatus of the third embodiment, and corresponds to FIG. 2 of the first embodiment. FIG. 8 is a partially cutaway view showing a main part of the in-pipe purification apparatus of FIG. FIG. 9 is a cross-sectional view of the main part when cut along a plane including the line IX-IX in FIG. 7.

  The in-pipe purification apparatus 100b shown in FIG. 7 includes a separator 200, a carrier 400, and a spacer 600b. As shown in FIGS. 8 and 9, the spacer 600b includes a closing portion 610b, a fixing portion 620b, and a carrier holding portion 630b.

  The blocking portion 610b is a curved plate shape along the inner wall surface of the pipe line 910, and has contact surfaces 615b on both left and right ends. The contact surface 615b closes the deletion portion 215 by contacting the surface of the deletion portion 215 (see FIG. 9). As a result, even if a load is applied in the vertically downward direction, the width of the deletion portion 215 is maintained without narrowing. The portion where the closing portion 610b closes the deletion portion 215 is a part of the extending direction of the separator 200 (the axial direction of the pipe 910) as shown in FIG. By providing such spacers 600b at a plurality of locations in the direction, the width of the deletion portion 215 is stably maintained.

[Fifth Embodiment]
FIG. 19 is a schematic external perspective view of the in-pipe purification apparatus of the fifth embodiment. FIG. 20 is a schematic cross-sectional view taken along the plane including the line XX-XX in FIG.
An in-pipe purification apparatus 100k shown in FIG. 19 includes a separator 200, a carrier fixing member 300, a carrier 400, a spacer 600, and a separator fixing member 500k similar to those in the first embodiment.

As shown in FIGS. 19 and 20, the separator fixing member 500k is configured to be interposed between the separator 200 and the upper inner wall surface of the conduit 910 and to fix the separator 200 to the lower inner wall surface of the conduit 910. The
As shown in FIG. 20, the separator fixing member 500 k has a shape approximately along the upper inner wall surface of the pipe 910, and the cross-sectional shape thereof is line symmetric with respect to the same axis of symmetry as that of the separator 200. Separator fixing member 500k includes separator contact portions 510kL and 510kR disposed at both ends thereof, and conduit contact portions 520kL and 520kR disposed between separator contact portions 510kL and 510kR.

  Separator contact portions 510kL and 510kR are formed in a shape along the surfaces of both side portions of separator 200, and can be in contact with both side portions. The pipe line contact portions 520 kL and 520 kR are connected to the separator contact parts 510 kL and 510 kR, respectively, are formed in a curved plate shape having a curved surface along the upper inner wall surface of the pipe line 910, and come into contact with the upper inner wall surface. .

  As described above, the separator fixing member 500k is interposed between the separator 200 and the upper inner wall surface of the conduit 910, and the separator 200 and the conduit 910 at the separator contact portions 510kL and 510kR and the conduit contact portions 520kL and 520kR, respectively. The separator 200 can be fixed in the pipe 910 by contacting the upper inner wall surface of the pipe 910. In the present embodiment, as described above, the separator 200 is formed so as to occupy a part below the center of the internal space of the pipe line 910 in the pipe line 910. It is preferable at the point which prevents the movement to the circumferential direction from the position in 20, and / or the upward movement. As a result, the performance during use of the in-pipe purification device 100k can be stably secured.

  Before the separator fixing member 500k is disposed in the pipe 910, at least a part of the separator contact parts 510kL and 510kR and at least a part of the pipe contact parts 520kL and 520kR protrude outside the inner wall of the pipe 910. It is preferable to be molded in a shape. For example, the pipe contact portions 520 kL and 520 kR have a curved shape having a radius of curvature equal to or larger than the upper inner wall of the pipe line 910, and the separator contact portions 510 kL and 510 kR are on both sides of the separator 200 to which they should contact. You may shape | mold so that it may space apart rather than the width | variety.

  When the separator fixing member 500k formed in this way is installed in the duct 910 in which the separator 200 is accommodated in advance, the separator contact portions 510kL and 510kR are arranged closer to each other than the widths on both sides of the separator 200. After being flexibly deformed, the pipe 910 is made to enter. At the time of this flexible deformation, the uppermost portion of the separator fixing member 500k (so that the increase in the vertical width due to the deformation of the separator fixing member 500k does not hinder the entry into the duct 910 in which the separator 200 is accommodated in advance) It is preferable that the non-contact part 530k is provided between the pipe line contact parts 520kL and 520kR. The non-contact part 530k should just be comprised in the shape (flat plate shape in this embodiment) which does not contact the upper inner wall surface of the pipe line 910 in the pipe line 910. FIG.

  When the separator fixing member 500k is configured as described above, the pipe contact portions 520kL and 520kR and the separator contact portions 510kL and 510kR are respectively arranged at the upper part of the pipe 910 when fitted in the pipe 910. A load that stretches against the inner wall surface and both sides of the separator 200 is applied, and the separator 200 can be stably fixed.

  However, the present invention does not require the separator fixing member 500k to be formed in a shape that protrudes outside the inner wall of the conduit 910 as described above before being disposed in the conduit 910. You may shape | mold by the shape (shape which fits in the pipe line 910) shown by FIG.

  Further, the separator contact portions 510kL and 510kR do not require that both of them are always in contact with the separator 200 when the in-pipe purification device 100k is used. That is, the separator fixing member 500k may be formed such that the separator contact portion 510kL and the separator contact portion 510kR have a clearance between the separator 200 and the separator fixing member 500k. In this case, if the separator fixing member 500k is fixed to the inner wall of the conduit 910, the separator 200 (and the member fixed thereto) can be extracted after the use of the in-pipe purification device 100k. When the in-pipe purification device 100k is used, the separator 200 can move within the range of the clearance. However, when at least one of the separator contact portion 510kL and the separator contact portion 510kR contacts the separator 200, the separator 200 Excessive movement in the circumferential direction and / or upward direction can be prevented.

  It should be noted that an adhesive is interposed between the pipe contact portions 520 kL and 520 kR and the upper inner wall surface of the pipe line 910 and / or between the separator contact portions 510 kL and 510 kR and both sides of the separator 200. However, the present invention does not specifically exclude an embodiment in which no adhesive is interposed.

Separator fixing member 500k can be made of resin. The resin may be the same as the resin constituting the separator 200 or may be different. Examples of the resin include thermoplastic resins such as vinyl chloride resins and olefin resins, and thermosetting resins such as epoxy resins and unsaturated polyester resins. The resin may be in the form of a composite material, that is, FRP (fiber reinforced plastic) reinforced with a fiber material such as glass fiber or carbon fiber.
For manufacturing the separator fixing member 500k, a manufacturing method corresponding to the type of resin is selected. For example, a thermoplastic resin can be manufactured by injection molding. In the case of a thermosetting resin and FRP, it can be produced by a hand lay-up method, an RTM molding method, or the like.

  The separator fixing member 500k may also be applied to the above-described in-pipe purification devices 100a and 100b and the below-described in-pipe purification devices 100l, 100m, 100n, and 100p.

As shown in FIG. 22, the fixed portion 620 l has a fixed curved surface 621 l having a shape along the concave curved surface 211 of the support portion 210, and is fixed in contact with the concave curved surface 211. The fixed curved surface 621 l extends farther from the axis of symmetry than the carrier accommodating portion 640, and ensures a sufficient ground contact area to the concave curved surface 211. The same applies to the fixing portion 620l '.

  The protrusion 655l is formed as a protrusion that protrudes in the direction from the inside of the separator 200 toward the outside. In the present embodiment, the protrusion 655l extends from the boundary portion between the first insertion portion 651l and the second insertion portion 651l 'to the boundary portion between the fixing portions 620l and 620l' (see FIG. 21). The separators 200 are connected to each other by inserting the first insertion part 651l and the second insertion part 651l ′ into the end part of the separator 200 and inserting the end face of the separator 200 into contact with the protrusion part 655l. The In the present embodiment, when the separators 200 are connected by the joint portion 650l, the surface of the separator 200 and the top surface of the protrusion 655 are flush with each other. Specifically, the upper surface of the partition portion 250 and the top surface of the protrusion 655 are flush with each other, so that the flow of drainage is not hindered and the convex curved surface of the support portion 210 and the top surface of the protrusion 655 are flush. As a result, it is easy to ground the inner wall surface of the pipe line 910.

  In addition, although it is preferable that the adhesive agent is interposed in the contact part of the joint part 650l and the separator 200, this invention does not specifically exclude the aspect in which the adhesive agent is not interposed.
