Description

本発明は、ろ過体連結部材および該ろ過体連結部材を用いたろ過モジュールに関し、特に、質量が大きいろ過体の連結に用いられるろ過体連結部材、および、該ろ過体連結部材を用いて連結したろ過体をハウジング内に収容してなるろ過モジュールに関するものである。   The present invention relates to a filter connecting member and a filtration module using the filter connecting member, and in particular, a filter connecting member used for connecting a filter having a large mass, and the filter connecting member connected using the filter connecting member. The present invention relates to a filtration module in which a filter body is accommodated in a housing.

従来、上水処理システムや、下水処理システムや、海水淡水化システム等の各種水処理システムでは、例えば、耐久性に優れるセラミック製のろ過膜や金属製のろ過膜をろ過体として用いて被処理水をろ過している。   Conventionally, in various water treatment systems such as a water treatment system, a sewage treatment system, and a seawater desalination system, for example, a ceramic filtration membrane or a metal filtration membrane having excellent durability is used as a filter. The water is being filtered.

具体的には、上記水処理システムでは、例えば、図５に一部切り欠き断面を示すような、多数の管状膜２１１をレンコン状に一体化してなる長さ１ｍ程度のモノリス型の多孔質セラミック膜２１０を、シール部材２３０を介して円筒状のハウジング２２０内に液密状態で設置して構成したろ過モジュール２００を用いて被処理水をろ過している。そして、このろ過モジュール２００では、図５に矢印で水の流れを示すように、ろ過モジュール２００の一端側からモノリス型多孔質セラミック膜２１０の管状膜２１１内に流入した被処理水が該管状膜２１１でろ過され、得られたろ過水が、モノリス型多孔質セラミック膜２１０の外周面２１２と、ハウジング２２０の内周面２２２との間を通ってハウジング２２０に設けられた流出口２２１から流出する。また、ろ過モジュール２００では、定期的に、或いは、ろ過の継続に伴ってモノリス型多孔質セラミック膜２１０が閉塞した場合には、モノリス型多孔質セラミック膜２１０の外周面２１２側から管状膜２１１内に向かって逆洗水を流してモノリス型多孔質セラミック膜２１０を逆洗（逆流洗浄）している。   Specifically, in the water treatment system, for example, a monolithic porous ceramic having a length of about 1 m formed by integrating a number of tubular membranes 211 in a lotus shape as shown in a partially cutaway cross section in FIG. Water to be treated is filtered using a filtration module 200 configured by installing the membrane 210 in a liquid-tight state in the cylindrical housing 220 via the seal member 230. In the filtration module 200, the water to be treated that flows into the tubular membrane 211 of the monolith type porous ceramic membrane 210 from one end side of the filtration module 200 is shown in FIG. The filtered water obtained by filtration at 211 flows out from the outlet 221 provided in the housing 220 through between the outer peripheral surface 212 of the monolithic porous ceramic membrane 210 and the inner peripheral surface 222 of the housing 220. . Further, in the filtration module 200, when the monolithic porous ceramic membrane 210 is closed periodically or as the filtration is continued, the inside of the tubular membrane 211 is formed from the outer peripheral surface 212 side of the monolithic porous ceramic membrane 210. The monolith type porous ceramic membrane 210 is backwashed (backwashing) by flowing backwash water toward the surface.

ところで、近年、上述したようなハウジング内にろ過体（ろ過膜）を設置してなるろ過モジュールを用いた水処理システムにおいては、効率性の観点から、ろ過モジュールの設置面積低減およびコスト削減が求められている。   By the way, in recent years, in the water treatment system using the filtration module in which the filter body (filtration membrane) is installed in the housing as described above, it is required to reduce the installation area and cost of the filtration module from the viewpoint of efficiency. It has been.

そこで、ろ過モジュールの設置面積を低減可能なろ過モジュールの設置構造として、円筒状のハウジングの中心軸線が水平面と平行になるように横置きした複数のろ過モジュールを、鉛直方向に並列に配置した構造が提案されている（例えば、特許文献１参照）。   Therefore, as a filtration module installation structure that can reduce the installation area of the filtration module, a structure in which a plurality of filtration modules horizontally arranged so that the central axis of the cylindrical housing is parallel to the horizontal plane is arranged in parallel in the vertical direction. Has been proposed (see, for example, Patent Document 1).

特許第３８５７１６４号公報Japanese Patent No. 3857164

しかし、上記従来のろ過モジュールの設置構造では、横置きしたろ過モジュールを鉛直方向に並列配置して集積化することでろ過モジュールの設置面積を低減することはできるものの、長さ１ｍ程度のろ過体ごとにハウジング等を準備する必要があるため、コストを十分に削減することができなかった。   However, in the above conventional filtration module installation structure, the installation area of the filtration module can be reduced by arranging the horizontal filtration modules arranged in parallel in the vertical direction, but the filtration body is about 1 m in length. Since it is necessary to prepare a housing or the like every time, the cost could not be reduced sufficiently.

そのため、十分にコストを削減するためには、一つのハウジング内に収納するろ過体の長さを長くし、使用するハウジング等の数を低減する必要があった。即ち、ハウジング内に設置するセラミック製のろ過膜や金属製のろ過膜などのろ過体の長さを長くする必要があった。   Therefore, in order to sufficiently reduce the cost, it is necessary to increase the length of the filter body housed in one housing and reduce the number of housings and the like to be used. That is, it is necessary to increase the length of a filter body such as a ceramic filter membrane or a metal filter membrane installed in the housing.

ここで、ハウジング内に設置するろ過体の長さを長くする方法としては、ろ過体の長さを単純に長くする方法と、連結部材を用いて複数のろ過体をハウジング内で連結する方法とが考えられる。しかし、セラミック製または金属製のろ過体は、材質上、単位長さ当たりの質量が大きい（例えば、見掛け密度が１０００ｋｇ／ｍ3以上である）ため、ろ過体の長さを単純に長くする方法では、ろ過体の質量が非常に大きくなり、ろ過体のハンドリング性が悪化する。そのため、ハウジング内に設置するろ過体の長さを長くする方法としては、連結部材を用いて複数のろ過体を連結する方法が好ましい。また、連結部材を用いて複数のろ過体を連結する際には、質量の大きいろ過体を連結しながらハウジング内に挿入する操作を容易にする観点から、ろ過体の軸線が水平面と平行になるように横置きして連結することが特に好ましい。 Here, as a method of increasing the length of the filter body installed in the housing, a method of simply increasing the length of the filter body, and a method of connecting a plurality of filter bodies in the housing using a connecting member, Can be considered. However, a ceramic or metal filter body has a large mass per unit length due to its material (for example, the apparent density is 1000 kg / m 3 or more), and thus the filter body is simply lengthened. Then, the mass of the filter body becomes very large, and the handleability of the filter body deteriorates. Therefore, as a method for increasing the length of the filter body installed in the housing, a method of connecting a plurality of filter bodies using a connecting member is preferable. Moreover, when connecting a some filter body using a connection member, the axis of a filter body becomes parallel to a horizontal surface from a viewpoint which makes easy operation which inserts in a housing, connecting a filter body with a large mass. It is particularly preferable to connect in a horizontal manner.

しかし、上述したようなセラミック製または金属製のろ過体を連結するためには、連結部材でろ過体の荷重を支持しつつ、連結部分においてろ過体の一次側（被処理水流入側）から二次側（ろ過水流出側）へと被処理水が漏れ出さないように連結部分を確実にシールする必要がある。また、各ろ過体で被処理水をろ過して得たろ過水をハウジングの流出口から流出させ、或いは、各ろ過体を逆洗することができるように、ろ過体を連結部材で連結してなる組立体（連結ろ過体）の外周面とハウジングの内周面との間を水が流れ得るようにする必要がある。なお、連結部材でろ過体の荷重を支持しつつ連結部分を確実にシールすることは、ろ過体の軸線が水平面と平行になるように横置きした状態、或いは、ろ過体の軸線が水平面に対して傾斜するように斜め置きした状態でろ過体を連結する際に特に求められていた。   However, in order to connect the ceramic or metal filter body as described above, the connection member supports the load of the filter body, and at the connection portion, the filter body is moved from the primary side (treated water inflow side) to the second. It is necessary to securely seal the connecting portion so that the treated water does not leak to the next side (filtrated water outflow side). In addition, the filtered water obtained by filtering the water to be treated with each filter body is allowed to flow out from the outlet of the housing, or the filter bodies are connected with a connecting member so that each filter body can be backwashed. It is necessary to allow water to flow between the outer peripheral surface of the assembly (connected filter body) and the inner peripheral surface of the housing. It should be noted that to securely seal the connecting portion while supporting the load of the filter body with the connecting member is to place the filter body horizontally so that the axis of the filter body is parallel to the horizontal plane, or the axis of the filter body relative to the horizontal plane. In particular, the filter bodies are required to be connected in an inclined state so as to be inclined.

そこで、この発明は、ろ過体の荷重を支持しつつ連結部分を確実にシールすることを可能にし、且つ、連結したろ過体の周囲を水等の液体が流れることを可能にしたろ過体連結部材を提供することを目的とする。また、この発明は、該ろ過体連結部材を用いて連結したろ過体をハウジング内に収容してなるろ過モジュールを提供することを目的とする。   Accordingly, the present invention provides a filter connecting member that can reliably seal the connecting portion while supporting the load of the filter, and that allows liquid such as water to flow around the connected filter. The purpose is to provide. Moreover, this invention aims at providing the filtration module formed by accommodating the filter body connected using this filter body connection member in a housing.

この発明は、上記課題を有利に解決することを目的とするものであり、本発明のろ過体連結部材は、両端面間を貫通する少なくとも一つの貫通孔を有し、貫通孔内から外周面に向かって被処理水を通水してろ過水を得る柱状のろ過体同士、或いは、両端面間を貫通する少なくとも一つの貫通孔を有し、外周面から貫通孔内に向かって被処理水を通水してろ過水を得る柱状のろ過体同士を、横置き又は斜め置きした状態でろ過体の軸線方向に連結するろ過体連結部材であって、第１の内径を有し、連結されるろ過体が係止される筒状の縮径部と、前記縮径部の軸線方向両外側のそれぞれに該縮径部と一体的に配設され、前記第１の内径よりも大きい第２の内径を有して、連結されるろ過体が挿入される筒状の嵌合部と、前記縮径部の外周面および前記嵌合部の外周面の少なくとも一部と一体的に、且つ、前記縮径部および前記嵌合部の外周面側で縮径部および嵌合部の軸線と平行な方向に向かって液体が流通できるように配設された外周支持部とを備え、前記嵌合部の端面の少なくとも一部に、該嵌合部の軸線方向外方および径方向内方に向かって突出し、連結されるろ過体の荷重を支持する爪部を嵌合部と一体的に配設したことを特徴とする。このように、第１の内径を有する縮径部の軸線方向両側に第２の内径を有する嵌合部を配設すれば、連結されるろ過体の端面同士が縮径部を挟んで対向するようにろ過体を嵌合部に挿入することで、ろ過体の荷重を支持しつつろ過体同士を連結することができる。また、連結されるろ過体の端面の外周縁部が当接する縮径部の端面にゴムパッキン等のシール材を配設した状態でろ過体同士を連結すれば、連結部分を確実にシールすることができる。更に、縮径部および嵌合部の軸線と平行な方向に向かって液体が流通できるように外周支持部を配設すれば、連結したろ過体をハウジング等に収容した際に、連結したろ過体をハウジングの内周面に対して外周支持部で支持しつつ、連結したろ過体の周囲（連結したろ過体の外周面とハウジング内周面との間）に液体を流すことができる。 An object of the present invention is to advantageously solve the above-mentioned problem, and the filter connecting member of the present invention has at least one through-hole penetrating between both end surfaces, and the outer peripheral surface from the through-hole. The columnar filter bodies that pass the water to be treated to obtain filtered water, or have at least one through-hole penetrating between both end faces, and the water to be treated from the outer peripheral surface into the through-hole A filter body connecting member that connects columnar filter bodies that pass through water to obtain filtrate water in the axial direction of the filter body in a horizontally or obliquely placed state, and has a first inner diameter and is connected. A cylindrical reduced-diameter portion to which the filter body is locked, and a second diameter larger than the first inner diameter, which is integrally disposed with the reduced-diameter portion on both outer sides in the axial direction of the reduced-diameter portion. A cylindrical fitting portion into which a filter body to be connected is inserted, an outer peripheral surface of the reduced diameter portion, and The liquid is integrated with at least a part of the outer peripheral surface of the fitting portion and in the direction parallel to the axis of the reduced diameter portion and the fitting portion on the outer peripheral surface side of the reduced diameter portion and the fitting portion. And a peripheral support part arranged so as to be able to circulate, and is projected and connected to at least a part of the end face of the fitting part toward the axially outer side and the radial inner side of the fitting part. The nail | claw part which supports the load of a body is arrange | positioned integrally with the fitting part, It is characterized by the above-mentioned. Thus, if the fitting part which has a 2nd internal diameter is arrange | positioned at the axial direction both sides of the reduced diameter part which has a 1st internal diameter, the end surfaces of the filter body connected will oppose on both sides of a reduced diameter part. Thus, by inserting a filter body in a fitting part, filter bodies can be connected, supporting the load of a filter body. In addition, if the filter bodies are connected to each other in a state in which a sealing material such as rubber packing is disposed on the end face of the reduced diameter portion where the outer peripheral edge of the end face of the connected filter body abuts, the connecting portion can be reliably sealed. Can do. Furthermore, if the outer peripheral support part is arranged so that the liquid can flow in a direction parallel to the axis of the reduced diameter part and the fitting part, the connected filter body is accommodated when the connected filter body is accommodated in a housing or the like. Can be made to flow around the connected filter bodies (between the outer peripheral surface of the connected filter bodies and the housing inner peripheral surface) while supporting the inner peripheral surface of the housing with the outer peripheral support portion.

また、爪部を配設すれば、ろ過体を横置き或いは斜め置きした状態で連結する場合に、ろ過体の荷重を爪部で支持することができる。従って、ろ過体の連結される側の端面の外周縁部と、ろ過体の外周面の連結される側の端部とを一体的にシールするシール材を用いて連結部分をシールする場合であっても、ろ過体の荷重によりシール材が局所的に潰れるのを抑制することができる。即ち、連結部分をより確実にシールすることができると共に、シール材の劣化を抑制することができる。
Further, if the claw portion is provided, the load of the filter body can be supported by the claw portion when the filter body is connected in a state of being placed horizontally or obliquely. Therefore, the connecting portion is sealed using a sealing material that integrally seals the outer peripheral edge portion of the end face on the side to which the filter body is connected and the end portion on the side to which the outer peripheral face of the filter body is connected. However, it can suppress that a sealing material collapses locally by the load of a filter body . That is, the connecting portion can be more reliably sealed and the deterioration of the sealing material can be suppressed .

また、本発明のろ過体連結部材は、前記爪部の端面側の内面に、爪部の端縁から嵌合部側に向かってテーパー状に傾斜した傾斜面を有することが好ましい。傾斜面を設ければ、ろ過体を連結する際に、傾斜面を利用して嵌合部にろ過体を容易に挿入することができるからである。   Moreover, it is preferable that the filter body connection member of this invention has the inclined surface which inclined in the taper shape toward the fitting part side from the edge of the nail | claw part in the inner surface by the side of the end surface of the said nail | claw part. This is because if the inclined surface is provided, the filter body can be easily inserted into the fitting portion using the inclined surface when connecting the filter bodies.

更に、本発明のろ過体連結部材は、前記外周支持部が、前記嵌合部および前記縮径部の軸線と平行な方向に延在する３つ以上の突起からなり、前記突起が、前記縮径部および前記嵌合部の周方向に互いに等間隔で配設されていることが好ましい。突起を周方向に互いに等間隔で配設して外周支持部を形成すれば、縮径部および嵌合部の外周面側での液体の均等な流通を可能にしつつ、ろ過体連結部材を用いて連結したろ過体をハウジング等に収容した状態で搬送する際などに、ハウジング内でろ過体が自由に動くのを防止することができるからである。   Furthermore, in the filter connecting member of the present invention, the outer peripheral support portion includes three or more protrusions extending in a direction parallel to the axis of the fitting portion and the reduced diameter portion, and the protrusion is the contraction member. It is preferable that they are arranged at equal intervals in the circumferential direction of the diameter portion and the fitting portion. If the protrusions are arranged at equal intervals in the circumferential direction to form the outer peripheral support part, the filter connecting member is used while allowing the liquid to be evenly distributed on the outer peripheral surface side of the reduced diameter part and the fitting part. This is because it is possible to prevent the filter body from freely moving within the housing when the connected filter body is conveyed in a state of being accommodated in the housing or the like.

また、この発明は、上記課題を有利に解決することを目的とするものであり、本発明のろ過モジュールは、両端面間を貫通する少なくとも一つの貫通孔を有し、貫通孔内から外周面に向かって被処理水を通水してろ過水を得る柱状のろ過体同士、或いは、両端面間を貫通する少なくとも一つの貫通孔を有し、外周面から貫通孔内に向かって被処理水を通水してろ過水を得る柱状のろ過体同士を、上記ろ過体連結部材の何れかを用いて、横置き又は斜め置きした状態でろ過体の軸線方向に連結した連結ろ過体と、前記連結ろ過体の外径よりも大きい内径を有する筒状のハウジングと、前記連結ろ過体の両端部のそれぞれに取り付けられ、前記ハウジングの内部に収容された連結ろ過体を、該連結ろ過体の軸線方向内方に向かって押圧した状態でハウジング内に固定すると共に、ハウジングの内周面と連結ろ過体の外周面との間に形成された空間を液密に封止する端部固定部材と、前記ハウジング外から前記ろ過体の貫通孔へ液体を供給し、或いは、前記ろ過体の貫通孔から前記ハウジング外へ液体を流出させる第１の流路と、前記ハウジングの内周面と連結ろ過体の外周面との間に形成された空間から前記ハウジング外へ液体を流出させ、或いは、前記ハウジング外から前記ハウジングの内周面と連結ろ過体の外周面との間に形成された空間へ液体を供給する第２の流路とを備えることを特徴とする。このように、上述したろ過体連結部材を用いれば、ろ過体の荷重を支持しつつ連結部分を確実にシールすることができると共に、連結ろ過体の外周面とハウジングの内周面との間に水等の液体を流すことができる。また、上述したろ過体連結部材を用いて連結された複数のろ過体（連結ろ過体）をハウジング内に収容してろ過モジュールとすれば、一つのハウジング内に収納するろ過体の長さを長くし、コストを削減することができる。即ち、ろ過体ごとにハウジングを準備する場合と比較して、使用するハウジング等の数を低減し、コストを削減することができる。 Moreover, this invention aims at solving the said subject advantageously, The filtration module of this invention has at least 1 through-hole penetrated between both end surfaces, and it is an outer peripheral surface from the inside of a through-hole. The columnar filter bodies that pass the water to be treated to obtain filtered water, or have at least one through-hole penetrating between both end faces, and the water to be treated from the outer peripheral surface into the through-hole Connected filter bodies connected in the axial direction of the filter body in a state of being placed horizontally or obliquely using any of the above-mentioned filter body connecting members, and the columnar filter bodies that pass through water to obtain filtered water, A cylindrical housing having an inner diameter larger than the outer diameter of the connected filter body, and a connected filter body attached to both ends of the connected filter body and housed in the housing, are connected to the axis of the connected filter body. In a state of pressing inward An end fixing member for liquid-tightly sealing a space formed between the inner peripheral surface of the housing and the outer peripheral surface of the connected filter body, and a through hole of the filter body from the outside of the housing. Formed between the first flow path for supplying liquid to the liquid or flowing the liquid out of the housing from the through hole of the filter body, and the inner peripheral surface of the housing and the outer peripheral surface of the connecting filter body. A second flow path for flowing liquid out of the housing from the space, or for supplying liquid from outside the housing to the space formed between the inner peripheral surface of the housing and the outer peripheral surface of the connecting filter body; It is characterized by providing. As described above, when the above-described filter body connecting member is used, the connecting portion can be reliably sealed while supporting the load of the filter body, and between the outer peripheral surface of the connected filter body and the inner peripheral surface of the housing. A liquid such as water can flow. Moreover, if the several filter body (connection filter body) connected using the filter connection member mentioned above is accommodated in a housing and it is set as a filtration module, the length of the filter body accommodated in one housing will be lengthened. And cost can be reduced. That is, compared with the case where a housing is prepared for each filter body, the number of housings to be used can be reduced, and the cost can be reduced.

そして、本発明のろ過モジュールは、前記ハウジングが、前記端部固定部材を固定するための環状溝を内周面に有し、前記端部固定部材が、前記ハウジングの内径に対応した外径と、前記ろ過体の外径に対応した内径とを有する筒状の拡径部と、前記拡径部の軸線方向一端側に該拡径部と一体的に配設され、前記拡径部の内径よりも小さい内径を有して前記連結ろ過体が係止される筒状の係止部と、前記係止部の内径よりも小さい内径と、前記係止部の外径よりも小さい外径とを有し、外周面に前記環状溝と嵌合するリング部材が配設される筒状の縮径部と、前記拡径部と前記縮径部とを軸線方向に一体的に連結するテーパー部とを有し、前記端部固定部材の内側空間が前記第１の流路を形成することが好ましい。拡径部よりも内径の小さな係止部を有する端部固定部材を用いれば、連結ろ過体の端面の外周縁部が当接する係止部の端面にゴムパッキン等のシール材を配設した状態で連結ろ過体をハウジング内に固定することができるからである。また、環状溝とリング部材とを用いれば、端部固定部材をハウジングに容易に固定することができるからである。更に、拡径部とテーパー部との間に筒状の係止部を設ければ、連結ろ過体の端面とテーパー部との間の距離を確保して、連結ろ過体の端面近傍で液体を良好に流すことができるからである。
なお、本発明において、「ハウジングの内径に対応した外径」とは、Ｏリング等のシール材を介してハウジングの内周面に嵌合させ得る外径を指し、「ろ過体の外径に対応した内径」とは、ゴムパッキン等のシール材を介してろ過体の外周面と嵌合し得る内径を指す。 In the filtration module of the present invention, the housing has an annular groove for fixing the end fixing member on the inner peripheral surface, and the end fixing member has an outer diameter corresponding to the inner diameter of the housing. A cylindrical enlarged diameter portion having an inner diameter corresponding to the outer diameter of the filter body, and the enlarged diameter portion is integrally disposed on one end side in the axial direction of the enlarged diameter portion. A cylindrical locking part having an inner diameter smaller than that of the coupling filter, an inner diameter smaller than the inner diameter of the locking part, and an outer diameter smaller than the outer diameter of the locking part; A cylindrical reduced-diameter portion in which a ring member fitted to the annular groove is disposed on the outer peripheral surface, and a tapered portion integrally connecting the enlarged-diameter portion and the reduced-diameter portion in the axial direction It is preferable that the inner space of the end fixing member forms the first flow path. When an end fixing member having a locking portion having an inner diameter smaller than the enlarged diameter portion is used, a sealing material such as rubber packing is disposed on the end surface of the locking portion with which the outer peripheral edge of the end surface of the coupled filter body abuts. This is because the coupled filter can be fixed in the housing. Moreover, if the annular groove and the ring member are used, the end fixing member can be easily fixed to the housing. Furthermore, if a cylindrical locking part is provided between the enlarged diameter part and the taper part, a distance between the end face of the connected filter body and the taper part is secured, so that liquid can be supplied near the end face of the connected filter body. It is because it can flow well.
In the present invention, the “outer diameter corresponding to the inner diameter of the housing” refers to an outer diameter that can be fitted to the inner peripheral surface of the housing via a sealing material such as an O-ring. The "corresponding inner diameter" refers to an inner diameter that can be fitted to the outer peripheral surface of the filter body through a sealing material such as rubber packing.

本発明のろ過体連結部材によれば、ろ過体の荷重を支持しつつ連結部分を確実にシールすることができると共に、連結したろ過体の周囲に水等の液体を流すことができる。また、本発明によれば、該ろ過体連結部材を用いて連結したろ過体をハウジング内に収容してなるろ過モジュールを提供することができる。   According to the filter connecting member of the present invention, the connecting portion can be reliably sealed while supporting the load of the filter, and a liquid such as water can flow around the connected filter.

The filter body connecting member of the present invention is used when connecting a columnar filter body having a relatively large mass, for example, a columnar ceramic filter membrane or a columnar metal filter membrane in the axial direction of the filter body. And the filter body connection member of the present invention is such that the connected filter bodies are placed horizontally (installed so that the axis of the filter body is parallel to the horizontal plane) or placed obliquely (the axis of the filter body is inclined with respect to the horizontal plane). When installing and using, it can use especially suitably. Moreover, the filtration module of this invention accommodates the filter body (connection filter body) connected using the filter body connection member of this invention in a housing, It is characterized by the above-mentioned. And the filtration module of this invention is used when filtering to-be-processed water in various water treatment systems, such as a water-treatment system, a sewage-treatment system, and a seawater desalination system.

ここで、本発明のろ過モジュールの一例について、一部を切り欠いて図１に示す。図１に示すろ過モジュール１００は、ろ過体としての円柱状セラミックろ過膜１０を該セラミックろ過膜１０の軸線方向（図１では左右方向）に例えば３本連結してなる連結ろ過体を、ハウジングとしての円筒状ベッセル４０に液密に収容および固定してなる。そして、このろ過モジュール１００では、セラミックろ過膜１０同士は、本発明のろ過体連結部材の一例のろ過体連結部材２０を介して連結されている。なお、図１では、切り欠き断面の一部を拡大して示している。   Here, about an example of the filtration module of this invention, a part is notched and it shows in FIG. A filtration module 100 shown in FIG. 1 has, as a housing, a connected filter body formed by connecting, for example, three cylindrical ceramic filter membranes 10 as filter bodies in the axial direction of the ceramic filter membrane 10 (left-right direction in FIG. 1). The cylindrical vessel 40 is housed and fixed in a liquid-tight manner. And in this filtration module 100, ceramic filtration membranes 10 are connected via the filter body connection member 20 of an example of the filter body connection member of this invention. In addition, in FIG. 1, a part of notch cross section is expanded and shown.

＜ろ過体＞
ろ過体としてのセラミックろ過膜１０は、円柱状で、図１に断面を示すように、両端面間をセラミックろ過膜１０の軸線方向に貫通する複数の貫通孔１１を有している。また、セラミックろ過膜１０の体積密度（見掛け密度＝セラミックろ過膜の質量／セラミックろ過膜の嵩体積）は、例えば１０００ｋｇ／ｍ3以上と比較的大きい。そして、セラミックろ過膜１０の貫通孔１１の周囲には、被処理水をろ過するための分離層（図示せず）が設けられている。 <Filter body>
The ceramic filtration membrane 10 as a filter body is cylindrical, and has a plurality of through holes 11 that penetrate between both end faces in the axial direction of the ceramic filtration membrane 10 as shown in a cross section in FIG. The volume density of the ceramic filtration membrane 10 (apparent density = mass of the ceramic filtration membrane / bulk volume of the ceramic filtration membrane) is relatively large, for example, 1000 kg / m 3 or more. A separation layer (not shown) for filtering the water to be treated is provided around the through hole 11 of the ceramic filtration membrane 10.

即ち、このセラミックろ過膜１０は、各貫通孔１１の周囲に分離層を形成してなる複数の管状膜を、支持層を介してレンコン状に一体化してなるモノリス型の多孔質セラミック膜である。そして、このセラミックろ過膜１０では、図１に矢印で水の流れを示すように、貫通孔１１内からセラミックろ過膜１０の外周面１２側に向かって被処理水を通水することで、ろ過水を得ることができる。また、このセラミックろ過膜１０では、ろ過時とは逆方向に、即ち、外周面１２側から貫通孔１１内に向かって逆洗水を流すことで、セラミックろ過膜１０を逆流洗浄することができる。   That is, the ceramic filtration membrane 10 is a monolithic porous ceramic membrane formed by integrating a plurality of tubular membranes formed with separation layers around each through-hole 11 into a lotus shape through a support layer. . And in this ceramic filtration membrane 10, as shown to the flow of water by the arrow in FIG. 1, by passing water to be treated from the inside of the through hole 11 toward the outer peripheral surface 12 side of the ceramic filtration membrane 10, filtration is performed. You can get water. Moreover, in this ceramic filtration membrane 10, the ceramic filtration membrane 10 can be backwashed by flowing backwash water in the opposite direction to the time of filtration, that is, by flowing backwash water from the outer peripheral surface 12 side into the through hole 11. .

なお、本発明のろ過体連結部材で連結するろ過体、或いは、本発明のろ過モジュールで用いるろ過体は、上記一例とは逆方向に被処理水を通水してろ過水を得るろ過体であっても良い。具体的には、本発明では、例えば、円柱状で、両端面間を貫通する貫通孔と、ろ過体の外周面に沿って形成された分離膜とを有し、外周面から貫通孔内に向かって被処理水を通水してろ過水を得るろ過体をろ過体連結部材で連結してろ過モジュールに用いても良い。   In addition, the filter body connected by the filter body connection member of the present invention or the filter body used in the filter module of the present invention is a filter body that obtains filtered water by passing water to be treated in the opposite direction to the above example. There may be. Specifically, in the present invention, for example, a cylindrical shape having a through-hole penetrating between both end surfaces and a separation membrane formed along the outer peripheral surface of the filter body, the outer peripheral surface into the through-hole You may connect the filter body which passes a to-be-processed water toward and obtains filtered water with a filter body connection member, and may use it for a filtration module.

＜ろ過体連結部材＞
ろ過体としてのセラミックろ過膜１０を軸線方向に連結するろ過体連結部材２０は、図２（ａ）に正面図、（ｂ）に平面図、（ｃ）に側面図、（ｄ）に底面図、（ｅ）に図２（ａ）のＩ−Ｉ線に沿う断面図をそれぞれ示すように、略円筒状をしている。 <Filter body connecting member>
The filter body connecting member 20 for connecting the ceramic filter membrane 10 as the filter body in the axial direction is a front view in FIG. 2 (a), a plan view in (b), a side view in (c), and a bottom view in (d). , (E) has a substantially cylindrical shape as shown in a sectional view taken along line II in FIG. 2 (a).

そして、図１および図２（ｅ）に示すように、ろ過体連結部材２０は、第１の内径Ｄ1を有する円筒状の縮径部２１と、第１の内径Ｄ1よりも大きい第２の内径Ｄ2を有し、且つ、縮径部２１の軸線方向（図１および図２（ｅ）では左右方向）両外側のそれぞれに縮径部２１と一体的に配設された円筒状の嵌合部２２と、各嵌合部２２の端面の少なくとも一部に嵌合部２２と一体的に配設された爪部２３と、縮径部２１の外周面および嵌合部２２の外周面の少なくとも一部と一体的に配設された外周支持部としての複数の突起２５とを備えている。なお、ろ過体連結部材２０は、特に限定されることなく、硬質塩化ビニル樹脂や、ガラス繊維入りポリプロピレン樹脂などの耐薬品性の高い樹脂を用いて作製することができる。 Then, as shown in FIG. 1 and FIG. 2 (e), the filtration body coupling member 20 has a cylindrical reduced diameter portion 21 having a first inner diameter D 1, it is larger than the first inner diameter D 1 second of has an inner diameter D 2, and the axial direction of the reduced diameter portion 21 (FIGS. 1 and 2 (e) in the left-right direction) in each of the two outer Chijimi径部21 integrally disposed to the cylindrical The fitting portion 22, the claw portion 23 integrally disposed with the fitting portion 22 on at least a part of the end surface of each fitting portion 22, the outer peripheral surface of the reduced diameter portion 21, and the outer peripheral surface of the fitting portion 22 And a plurality of protrusions 25 as outer peripheral support portions disposed integrally with at least a part of the outer peripheral support portion. In addition, the filter body connection member 20 can be manufactured using resin with high chemical resistance, such as hard vinyl chloride resin and polypropylene resin containing glass fiber, without being specifically limited.

縮径部２１は、図１および図２（ｅ）に示すように、略円筒状のろ過体連結部材２０の軸線方向中央部に位置している。また、図１に示すように、縮径部２１の内径Ｄ1は、嵌合部２２の内径Ｄ2よりも小さく、且つ、ろ過体連結部材２０を用いて連結されるセラミックろ過膜１０の外径（即ち、円柱状のセラミックろ過膜１０の端面の直径）よりも小さい。 As shown in FIG. 1 and FIG. 2 (e), the reduced diameter portion 21 is located at the center in the axial direction of the substantially cylindrical filter body connecting member 20. Further, as shown in FIG. 1, the inner diameter D 1 of the reduced diameter portion 21 is smaller than the inner diameter D 2 of the fitting portion 22 and is outside the ceramic filtration membrane 10 connected using the filter body connecting member 20. It is smaller than the diameter (that is, the diameter of the end face of the cylindrical ceramic filtration membrane 10).

そして、図１に示すように、セラミックろ過膜１０を連結する際には、縮径部２１には、シール材としてのゴムパッキン６０を介してセラミックろ過膜１０が液密に係止される。即ち、嵌合部２２の内径Ｄ2と縮径部２１の内径Ｄ1との差の半分（＝（Ｄ2−Ｄ1）／２）の大きさだけ嵌合部２２の内周面よりもろ過体連結部材２０の径方向内方に突出する縮径部２１の各端面（換言すれば、縮径部２１と嵌合部２２とで形成される段差部分）に、セラミックろ過膜１０の連結される側の端面の外周縁部がゴムパッキン６０を介して係止される。 As shown in FIG. 1, when connecting the ceramic filtration membrane 10, the ceramic filtration membrane 10 is liquid-tightly locked to the reduced diameter portion 21 via a rubber packing 60 as a sealing material. That is, the inner diameter D 2 of the fitting portion 22 and the inner diameter D 1 of the reduced diameter portion 21 are half the difference (= (D 2 −D 1 ) / 2) from the inner peripheral surface of the fitting portion 22. The ceramic filtration membrane 10 is connected to each end face of the reduced diameter portion 21 protruding inward in the radial direction of the filter body connecting member 20 (in other words, a step portion formed by the reduced diameter portion 21 and the fitting portion 22). The outer peripheral edge portion of the end face on the side to be used is locked via the rubber packing 60.

嵌合部２２は、図１および図２（ｅ）に示すように、円筒状の縮径部２１の軸線方向両外側にそれぞれ位置している。また、各嵌合部２２は、縮径部２１と外径が等しく、且つ、縮径部２１と同軸に配設されている。更に、嵌合部２２の内径Ｄ2は、ろ過体連結部材２０を用いて連結されるセラミックろ過膜１０の外径よりも大きい。 As shown in FIG. 1 and FIG. 2 (e), the fitting portions 22 are respectively located on both outer sides in the axial direction of the cylindrical reduced diameter portion 21. Each fitting portion 22 has the same outer diameter as the reduced diameter portion 21 and is disposed coaxially with the reduced diameter portion 21. Furthermore, the inner diameter D 2 of the fitting portion 22 is larger than the outer diameter of the ceramic filtration membrane 10 connected using the filter connecting member 20.

そして、図１に示すように、セラミックろ過膜１０を連結する際には、嵌合部２２の内周面側には、シール材としてのゴムパッキン６０を介してセラミックろ過膜１０が挿入される。従って、嵌合部２２は、連結されるセラミックろ過膜１０の外周面形状に対応した内周面形状を有している。即ち、嵌合部２２は、シール材としてのゴムパッキン６０を介して、ろ過体連結部材２０にセラミックろ過膜１０を液密に挿入および係止し得るような形状および寸法とされている。   As shown in FIG. 1, when connecting the ceramic filtration membrane 10, the ceramic filtration membrane 10 is inserted into the inner peripheral surface side of the fitting portion 22 via a rubber packing 60 as a sealing material. . Therefore, the fitting part 22 has an inner peripheral surface shape corresponding to the outer peripheral surface shape of the ceramic filtration membrane 10 to be connected. In other words, the fitting portion 22 has a shape and dimensions that allow the ceramic filtration membrane 10 to be inserted and locked into the filter body connecting member 20 in a liquid-tight manner via a rubber packing 60 as a seal material.

なお、本発明のろ過体連結部材では、嵌合部とろ過体との間にシール材を介在させることなく、ろ過体の端面の外周縁部と縮径部の端面との間のみに環状のシール材を介在させた状態でろ過体を連結しても良い。そして、嵌合部とろ過体との間にシール材を介在させることなくろ過体を連結させるろ過体連結部材では、嵌合部の内周面形状は、ろ過体と直接嵌合し得る形状にすることができる。   In the filter connecting member of the present invention, an annular ring is formed only between the outer peripheral edge of the end face of the filter body and the end face of the reduced diameter part without interposing a sealant between the fitting part and the filter body. You may connect a filter body in the state which interposed the sealing material. And in the filter body connection member which connects a filter body without interposing a sealing material between a fitting part and a filter body, the inner peripheral surface shape of a fitting part is a shape which can be directly fitted with a filter body. can do.

爪部２３は、図１および図２（ａ），（ｂ），（ｅ）に示すように、嵌合部２２の縮径部２１側とは反対側の端面の一部に、嵌合部２２から軸線方向外方に突出するように配設されている。また、爪部２３は、嵌合部２２の内周面よりもろ過体連結部材２０の径方向内方（即ち、円筒状の嵌合部２２の径方向内方）に突出する部分を有している。更に、爪部２３の嵌合部２２側とは反対側の端部の内面には、爪部２３の端縁から嵌合部２２側に向かってテーパー状に傾斜した傾斜面２４が設けられている。即ち、爪部２３の傾斜面２４が形成されている部分の厚さは、嵌合部２２側に向かって次第に厚くなっている。   As shown in FIGS. 1 and 2A, 2B, and 2E, the claw portion 23 is formed on a part of the end surface of the fitting portion 22 on the side opposite to the reduced diameter portion 21 side. It is arranged so as to protrude outward in the axial direction from 22. Further, the claw portion 23 has a portion that protrudes inward in the radial direction of the filter body connecting member 20 from the inner peripheral surface of the fitting portion 22 (that is, inward in the radial direction of the cylindrical fitting portion 22). ing. Furthermore, an inclined surface 24 inclined in a taper shape from the edge of the claw 23 toward the fitting portion 22 is provided on the inner surface of the end of the claw 23 opposite to the fitting portion 22 side. Yes. In other words, the thickness of the portion of the claw portion 23 where the inclined surface 24 is formed gradually increases toward the fitting portion 22 side.

そして、図１に示すように、セラミックろ過膜１０を連結する際には、連結されるセラミックろ過膜１０の下側（連結ろ過体を横置きした際にセラミックろ過膜１０の荷重を受ける側）に爪部２３が位置するように配置したろ過体連結部材２０の嵌合部２２にセラミックろ過膜１０が挿入される。即ち、嵌合部２２および爪部２３上にセラミックろ過膜１０が載置され、嵌合部２２および爪部２３がセラミックろ過膜１０を支持する。従って、爪部２３が嵌合部２２の内周面よりもろ過体連結部材２０の径方向内方に突出する（立ち上がる）高さは、嵌合部２２の内周面に配置されるゴムパッキン６０の厚さと略等しい。より具体的には、爪部２３が突出する高さは、ろ過体連結部材２０にセラミックろ過膜１０を挿入し、且つ、セラミックろ過膜１０内に水を充填した状態におけるゴムパッキン６０の厚さと等しい。   And when connecting the ceramic filtration membrane 10 as shown in FIG. 1, the lower side of the ceramic filtration membrane 10 to be connected (the side receiving the load of the ceramic filtration membrane 10 when the connected filtration body is placed horizontally). The ceramic filtration membrane 10 is inserted into the fitting portion 22 of the filter body connecting member 20 that is arranged so that the claw portion 23 is positioned at the bottom. That is, the ceramic filtration membrane 10 is placed on the fitting portion 22 and the claw portion 23, and the fitting portion 22 and the claw portion 23 support the ceramic filtration membrane 10. Accordingly, the height at which the claw portion 23 protrudes (rises) radially inward of the filter body connecting member 20 from the inner peripheral surface of the fitting portion 22 is the rubber packing disposed on the inner peripheral surface of the fitting portion 22. It is approximately equal to 60 thickness. More specifically, the height at which the claw portion 23 protrudes is equal to the thickness of the rubber packing 60 in a state where the ceramic filtration membrane 10 is inserted into the filter body connecting member 20 and the ceramic filtration membrane 10 is filled with water. equal.

なお、本発明のろ過体連結部材では、爪部を配設しなくても良いが、特に、ろ過体の端面の外周縁部とろ過体の端部の外周面とを一体的に覆うシール材を用いてろ過体を連結する場合には、爪部を配設することが好ましい。爪部を配設すれば、嵌合部以外に爪部でもろ過体の荷重を負担することができるので、嵌合部に配置されたシール材の一部、特に横置きしたろ過体の端部下側を覆う部分にろ過体の荷重がかかってシール材が局所的に潰れて変形するのを防止することができるからである。即ち、シール材の局所的な変形の発生を防止して、ろ過体の連結部分のシール性が低下するのを防止することができると共に、シール材の劣化を抑制することができるからである。因みに、本発明のろ過体連結部材では、爪部を形成する範囲は、ろ過体の荷重を負担してシール材の局所的な変形を抑制し得る範囲であれば任意の範囲とすることができる。従って、爪部は、嵌合部の端面全体に設けても良いし、爪部を形成した部分の中心角の大きさが例えば３０〜１２０°となる範囲に設けても良い。   In addition, in the filter body connection member of the present invention, the claw portion does not need to be provided, but in particular, a sealing material that integrally covers the outer peripheral edge portion of the end surface of the filter body and the outer peripheral surface of the end portion of the filter body. It is preferable to arrange the claw portion when the filter bodies are connected using. If the claw part is provided, the load of the filter body can be borne by the claw part as well as the fitting part. Therefore, a part of the sealing material arranged in the fitting part, particularly under the end of the horizontally placed filter body This is because it is possible to prevent the sealing material from being locally crushed and deformed by applying a load of the filter body to the portion covering the side. That is, local deformation of the sealing material can be prevented to prevent the sealing performance of the connecting portion of the filter body from being lowered, and deterioration of the sealing material can be suppressed. Incidentally, in the filter connecting member of the present invention, the range in which the claw portion is formed can be any range as long as the load of the filter body can be borne and the local deformation of the sealing material can be suppressed. . Therefore, the claw portion may be provided on the entire end surface of the fitting portion, or may be provided in a range in which the central angle of the portion where the claw portion is formed is, for example, 30 to 120 °.

また、本発明のろ過体連結部材では、爪部にテーパー状の傾斜面を形成しなくても良いが、嵌合部へのろ過体の挿入を容易にする観点からは、爪部に傾斜面を形成することが好ましい。傾斜面を形成すれば、ろ過体を連結する際に、傾斜面を利用して嵌合部へろ過体を容易に挿入することができるからである。   Further, in the filter connecting member of the present invention, it is not necessary to form a tapered inclined surface on the claw portion, but from the viewpoint of facilitating the insertion of the filter body into the fitting portion, the inclined surface is formed on the claw portion. Is preferably formed. This is because if the inclined surface is formed, the filter body can be easily inserted into the fitting portion using the inclined surface when connecting the filter bodies.

外周支持部としての突起２５は、図１および図２（ａ）〜（ｅ）に示すように、縮径部２１および嵌合部２２の外周面上に、周方向に等間隔で合計８つ配設されている。また、突起２５は、ろ過体連結部材２０の縮径部２１および嵌合部２２の軸線と平行な方向（軸線方向）に延在しており、突起２５の軸線方向の長さは、縮径部２１および嵌合部２２の軸線方向の合計長さと略等しい。より詳細には、縮径部２１および嵌合部２２の外周面のうち、軸線方向両側に爪部２３が形成されていない範囲には、５つの突起２５が、縮径部２１および嵌合部２２の軸線方向の合計長さよりも若干短い長さで配設されている。また、縮径部２１および嵌合部２２の外周面のうち、軸線方向両側に爪部２３が形成されている範囲では、３つの突起２５が、縮径部２１、嵌合部２２および爪部２３の外周面上に、縮径部２１および嵌合部２２の軸線方向の合計長さよりも長く、且つ、縮径部２１、嵌合部２２および爪部２３の軸線方向の合計長さよりも若干短い長さで配設されている。   As shown in FIG. 1 and FIGS. 2A to 2E, a total of eight protrusions 25 as outer peripheral support portions are provided at equal intervals in the circumferential direction on the outer peripheral surfaces of the reduced diameter portion 21 and the fitting portion 22. It is arranged. Further, the protrusion 25 extends in a direction (axial direction) parallel to the axis of the reduced diameter portion 21 and the fitting portion 22 of the filter body connecting member 20, and the length of the protrusion 25 in the axial direction is reduced in diameter. The total length of the portion 21 and the fitting portion 22 in the axial direction is substantially equal. More specifically, in the range where the claw portions 23 are not formed on both sides in the axial direction on the outer peripheral surfaces of the reduced diameter portion 21 and the fitting portion 22, the five protrusions 25 are connected to the reduced diameter portion 21 and the fitting portion. The length of 22 is slightly shorter than the total length in the axial direction. In addition, in the range where the claw portions 23 are formed on both sides in the axial direction on the outer peripheral surfaces of the reduced diameter portion 21 and the fitting portion 22, the three protrusions 25 are connected to the reduced diameter portion 21, the fitting portion 22, and the claw portion. 23 is longer than the total length of the reduced diameter portion 21 and the fitting portion 22 in the axial direction, and slightly longer than the total length of the reduced diameter portion 21, the fitting portion 22 and the claw portion 23 in the axial direction. It is arranged with a short length.

更に、図１に示すように、突起２５の高さは、縮径部２１および嵌合部２２の外周面上に突起２５を一体的に形成してなるろ過体連結部材２０の外径（突起２５を含む最大外径）Ｄ3が、ベッセル４０の内径よりも小さくなるように設計されている。より詳細には、突起２５は、ろ過体連結部材２０でセラミックろ過膜１０を連結してなる連結ろ過体を、ベッセル４０内に収容可能であり、且つ、ベッセルに収容した連結ろ過体がベッセル内で大きく遊動しない程度の高さとされている。 Further, as shown in FIG. 1, the height of the protrusion 25 is the outer diameter (protrusion) of the filter body connecting member 20 formed integrally with the protrusion 25 on the outer peripheral surface of the reduced diameter portion 21 and the fitting portion 22. maximum outer diameter) D 3 including 25, is designed to be smaller than the inner diameter of the vessel 40. In more detail, the protrusion 25 can accommodate the connection filter body formed by connecting the ceramic filtration membrane 10 with the filter body connecting member 20 in the vessel 40, and the connection filter body accommodated in the vessel is in the vessel. The height is such that it does not move greatly.

そして、図１に示すように、ろ過体連結部材２０を介してセラミックろ過膜１０を連結してなる連結ろ過体をベッセル４０内に収容する際には、突起２５がベッセル４０の内周面に当接して連結ろ過体を支持する。また、突起２５は、縮径部２１および嵌合部２２の外周面上に周方向に等間隔で配設されているので、連結ろ過体をベッセル４０内に収容した際に、ろ過体連結部材２０の外周面の突起２５が配設されていない部分と、ベッセル４０の内周面との間には、軸線方向に延びる空間が形成される。従って、ろ過体連結部材２０の縮径部２１および嵌合部２２の外周面側では、縮径部２１および嵌合部２２の軸線と平行な方向に向かって液体が均等に流通することができる。   And as shown in FIG. 1, when accommodating the connection filter body which connects the ceramic filter membrane 10 via the filter body connection member 20 in the vessel 40, the processus | protrusion 25 is on the inner peripheral surface of the vessel 40. It contacts and supports a connected filter body. Moreover, since the protrusion 25 is arrange | positioned by the circumferential direction at equal intervals on the outer peripheral surface of the reduced diameter part 21 and the fitting part 22, when accommodating a connection filter body in the vessel 40, a filter body connection member A space extending in the axial direction is formed between the portion of the outer peripheral surface 20 where the protrusions 25 are not disposed and the inner peripheral surface of the vessel 40. Therefore, on the outer peripheral surface side of the reduced diameter portion 21 and the fitting portion 22 of the filter body connecting member 20, the liquid can evenly flow in the direction parallel to the axis of the reduced diameter portion 21 and the fitting portion 22. .

なお、本発明のろ過体連結部材では、外周支持部としての突起の形状は適宜変更することができる。具体的には、例えば図４（ａ）に本発明のろ過体連結部材の一変形例の平面図を示すように、ろ過体連結部材２０Ａの突起２５Ａの形状は流線形状としても良い。このように、突起２５Ａの形状を流線形状とすれば、突起２５Ａの間に形成される空間を液体がより良好に流れることができる。なお、図４（ａ）中、符号２３Ａは爪部を示し、２４Ａは傾斜面を示す。   In addition, in the filter body connection member of this invention, the shape of the protrusion as an outer periphery support part can be changed suitably. Specifically, for example, as shown in a plan view of a modification of the filter connecting member of the present invention in FIG. 4A, the shape of the protrusion 25A of the filter connecting member 20A may be a streamline shape. Thus, if the shape of the protrusion 25A is a streamline shape, the liquid can flow better in the space formed between the protrusions 25A. In FIG. 4A, reference numeral 23A indicates a claw portion, and 24A indicates an inclined surface.

また、本発明のろ過体連結部材では、外周支持部は突起に限定されることはなく、縮径部および嵌合部の外周面側で軸線方向に液体が流通可能であり、且つ、連結ろ過体をハウジング（ベッセル）の内周面に支持可能であれば、任意の形状にすることができる。具体的には、例えば図４（ｂ）に本発明のろ過体連結部材の他の変形例の正面図を示すように、ろ過体連結部材２０Ｂの外周支持部２５Ｂは、縮径部２１Ｂおよび嵌合部２２Ｂの外周面上に一体的に配設され、且つ、縮径部２１Ｂおよび嵌合部２２Ｂの軸線方向に延びる貫通孔２６Ｂを有する筒状体としても良い。このように、外周支持部を筒状体とすれば、連結ろ過体をベッセル４０の内周面に良好に支持することができる。なお、図４（ｂ）中、符号２３Ｂは爪部を示す。   Further, in the filter connecting member of the present invention, the outer peripheral support portion is not limited to the protrusion, and the liquid can flow in the axial direction on the outer peripheral surface side of the reduced diameter portion and the fitting portion, and the connected filtration is performed. Any shape can be used as long as the body can be supported on the inner peripheral surface of the housing (vessel). Specifically, for example, as shown in FIG. 4 (b), a front view of another modified example of the filter connecting member of the present invention, the outer peripheral support portion 25B of the filter connecting member 20B includes the reduced diameter portion 21B and the fitting. It is good also as a cylindrical body which is integrally arrange | positioned on the outer peripheral surface of the joint part 22B, and has the through-hole 26B extended in the axial direction of the reduced diameter part 21B and the fitting part 22B. As described above, when the outer peripheral support portion is a cylindrical body, the connected filter body can be favorably supported on the inner peripheral surface of the vessel 40. In addition, in FIG.4 (b), the code | symbol 23B shows a nail | claw part.

そして、上述したろ過体連結部材２０によれば、セラミックろ過膜１０の端面同士が縮径部２１を挟んで対向するようにセラミックろ過膜１０を嵌合部２２に挿入することで、セラミックろ過膜１０同士を軸線方向に連結することができる。   And according to the filter connecting member 20 described above, the ceramic filtration membrane 10 is inserted into the fitting portion 22 so that the end faces of the ceramic filtration membrane 10 face each other with the reduced diameter portion 21 interposed therebetween, so that the ceramic filtration membrane is inserted. Tens can be connected in the axial direction.

ここで、各嵌合部２２は縮径部２１と同軸で配設されており、また、連結されるセラミックろ過膜１０の端部の外周面は、同軸で配設された嵌合部２２の内周面で支持される。従って、このろ過体連結部材２０では、セラミックろ過膜１０同士を良好な同軸度で連結することができる。なお、「同軸度」とは、ＪＩＳ Ｂ０１８２等に記載の「共通の軸線をもつように配置された二つの部分の軸線が一致していない程度」を指す。   Here, each fitting part 22 is arrange | positioned coaxially with the diameter reducing part 21, and the outer peripheral surface of the edge part of the ceramic filtration membrane 10 connected is the coaxial of the fitting part 22 arrange | positioned. Supported by the inner surface. Therefore, in this filter body connection member 20, the ceramic filtration membranes 10 can be connected with a good coaxiality. The “coaxiality” refers to “the degree to which the axes of two portions arranged so as to have a common axis do not coincide” described in JIS B0182.

また、ろ過体連結部材２０では、環状のゴム部材の外周縁に円筒状のゴム部材を一体的に配設してなるゴムパッキン６０を、縮径部２１の端面および嵌合部２２の内周面にシール材として配置すると共に、セラミックろ過膜１０を縮径部２１側に向かって軸線方向に押圧してセラミックろ過膜１０同士を連結している。従って、セラミックろ過膜１０の連結される側の端面の外周縁部および端部の外周面を一体的にシールして、連結ろ過体の一次側から二次側へと被処理水が漏れ出さないように連結部分を確実にシール（即ち、液密に封止）することができる。   Further, in the filter body connecting member 20, the rubber packing 60 in which a cylindrical rubber member is integrally disposed on the outer peripheral edge of the annular rubber member is connected to the end surface of the reduced diameter portion 21 and the inner periphery of the fitting portion 22. The ceramic filtration membranes 10 are connected to each other by pressing them in the axial direction toward the reduced diameter portion 21 while being arranged as a sealing material on the surface. Accordingly, the outer peripheral edge of the end face on the side to which the ceramic filtration membrane 10 is connected and the outer peripheral face of the end are integrally sealed so that the water to be treated does not leak from the primary side to the secondary side of the connected filter body. Thus, the connecting portion can be reliably sealed (that is, liquid-tightly sealed).

更に、ろ過体連結部材２０は、爪部２３を有しているので、セラミックろ過膜１０を横置き或いは斜め置きした状態で連結する場合であっても、セラミックろ過膜１０の大きな荷重を爪部２３で支持することができる。従って、セラミックろ過膜１０の荷重によりゴムパッキン６０が嵌合部２２の内周面側で局所的に潰れるのを抑制し、嵌合部２２の内周面のシール面圧を均一化することができる。そのため、ろ過体連結部材２０では、連結部分をより確実にシールすることができると共に、ゴムパッキン６０が局所的に潰れて劣化するのを抑制することができる。また、ろ過体連結部材２０の爪部２３には傾斜面２４が形成されているので、ろ過体連結部材２０では、傾斜面２４を利用してセラミックろ過膜１０を嵌合部２２へ容易に挿入することができる。   Furthermore, since the filter body connecting member 20 has the claw portion 23, even when the ceramic filtration membrane 10 is connected in a horizontally or obliquely placed state, a large load on the ceramic filtration membrane 10 is applied to the claw portion. 23 can be supported. Therefore, it is possible to suppress the rubber packing 60 from being locally crushed on the inner peripheral surface side of the fitting portion 22 due to the load of the ceramic filtration membrane 10 and to uniformize the seal surface pressure on the inner peripheral surface of the fitting portion 22. it can. Therefore, in the filter body connection member 20, while a connection part can be sealed more reliably, it can suppress that the rubber packing 60 is crushed and deteriorated locally. Moreover, since the inclined surface 24 is formed in the nail | claw part 23 of the filter body connection member 20, in the filter body connection member 20, the ceramic filtration membrane 10 is easily inserted in the fitting part 22 using the inclined surface 24. can do.

そして、このろ過体連結部材２０には、軸線方向に延びる突起２５が周方向に均等に配設されているので、連結ろ過体をベッセル４０（ハウジング）に配置した際に、連結ろ過体の外周面とベッセル４０の内周面との間で液体を均等に流通させることができる。従って、一本のベッセル４０内に連結ろ過体を設置した場合であっても、ベッセル４０内からのろ過水の流出口４１をセラミックろ過膜１０ごとに配設することなくろ過および逆洗を実施することができる。また、一本当たりの質量が大きいセラミックろ過膜１０を複数本連結してなる連結ろ過体は非常に重いため、連結ろ過体の設置時やメンテナンス時には、連結ろ過体をベッセル４０に収容した状態で搬送する必要があるが、ろ過体連結部材２０には突起２５が周方向に均等に配設されているので、搬送時にベッセル４０内で連結ろ過体が自由に動くのを防止することができる。   And since the protrusion 25 extended to an axial direction is equally arrange | positioned in the circumferential direction in this filter body connection member 20, when arrange | positioning a connection filter body in the vessel 40 (housing), the outer periphery of a connection filter body The liquid can be evenly distributed between the surface and the inner peripheral surface of the vessel 40. Therefore, even when a coupled filter is installed in one vessel 40, filtration and backwashing are performed without disposing the outlet 41 of filtrate from the vessel 40 for each ceramic filtration membrane 10. can do. Moreover, since the connection filter body formed by connecting a plurality of ceramic filtration membranes 10 having a large mass per one is very heavy, the connection filter body is accommodated in the vessel 40 during installation or maintenance of the connection filter body. Although it is necessary to convey, since the protrusion 25 is equally arrange | positioned in the circumferential direction at the filter body connection member 20, it can prevent that a connection filter body moves freely within the vessel 40 at the time of conveyance.

＜ろ過モジュール＞
図１に示すように、ろ過モジュール１００は、上記ろ過体連結部材２０を用いて連結したセラミックろ過膜よりなる連結ろ過体を、端部固定部材３０を用いてベッセル４０内に液密に収容および固定してなる。なお、連結ろ過体は、ろ過体連結部材２０内に配置したゴムパッキン６０を用いて連結部分を確実にシールするために、連結ろ過体の両端面から連結ろ過体の軸線方向内方に向かって所定の圧力をかけた状態でベッセル４０内に固定される。 <Filtration module>
As shown in FIG. 1, the filtration module 100 contains a connected filter body made of a ceramic filter membrane connected using the filter connection member 20 in a liquid-tight manner in a vessel 40 using an end fixing member 30. It is fixed. In addition, in order to seal a connection part reliably using the rubber packing 60 arrange | positioned in the filter body connection member 20, a connection filter body goes toward the axial direction inner side of a connection filter body from the both end surfaces. It is fixed in the vessel 40 in a state where a predetermined pressure is applied.

ここで、ベッセル４０としては、特に限定されることなく、繊維強化プラスチック（ＦＲＰ）製の、規格化されたＲＯ（半透膜）用ベッセルなどを用いることができる。規格化されたＦＲＰ製ＲＯ用ベッセルを用いれば、製造コストを削減することができると共に、ろ過モジュールを海水淡水化処理等で使用した場合でも、ベッセル４０が錆びることがないからである。   Here, the vessel 40 is not particularly limited, and a standardized vessel for RO (semi-permeable membrane) made of fiber reinforced plastic (FRP) can be used. This is because if the standardized FRP RO vessel is used, the manufacturing cost can be reduced, and the vessel 40 will not rust even when the filtration module is used for seawater desalination.

そして、図１に示すように、ベッセル４０は、円筒状で、ろ過体連結部材２０の外径Ｄ3と略等しい内径を有している。また、ベッセル４０には、連結ろ過体で被処理水をろ過して得たろ過水が流出する、第２の流路としての流出口４１が設けられている。なお、流出口４１は、連結ろ過体を逆洗する際には、逆洗水の流入口として機能する。更に、ベッセル４０の両端部の内周面には、端部固定部材３０を固定するための環状溝４２が形成されている。因みに、環状溝４２は、環状溝４２を用いて端部固定部材３０を固定した際に、両端を端部固定部材３０で挟まれた連結ろ過体が軸線方向内方に向かって所定の圧力で押圧される位置に形成されている。 As shown in FIG. 1, the vessel 40 is cylindrical and has an inner diameter substantially equal to the outer diameter D 3 of the filter body connecting member 20. Further, the vessel 40 is provided with an outlet 41 as a second flow path through which filtered water obtained by filtering the water to be treated with a connected filter body flows out. In addition, the outflow port 41 functions as an inflow port of backwashing water when the connected filter body is backwashed. Furthermore, an annular groove 42 for fixing the end fixing member 30 is formed on the inner peripheral surface of both ends of the vessel 40. Incidentally, when the end fixing member 30 is fixed by using the annular groove 42, the annular groove 42 has a predetermined pressure that the connected filter body sandwiched between the both ends by the end fixing member 30 is axially inward. It is formed at the pressed position.

また、図３（ａ）に正面図、（ｂ）に平面図、（ｃ）に側面図、（ｄ）に底面図、（ｅ）に図３（ａ）のＩＩ−ＩＩ線に沿う断面図をそれぞれ示すように、端部固定部材３０は、円筒状の拡径部３１と、拡径部３１の軸線方向一端側に該拡径部３１と一体的に配設された円筒状の係止部３２と、係止部３２の拡径部３１側とは反対側の端面に一体的に配設され、且つ、内周面が次第に縮径するテーパー部３４と、テーパー部３４の係止部３２側とは反対側の端面に一体的に配設された縮径部３３とを有している。   3A is a front view, FIG. 3B is a plan view, FIG. 3C is a side view, FIG. 3D is a bottom view, and FIG. 3E is a cross-sectional view taken along line II-II in FIG. As shown respectively, the end fixing member 30 has a cylindrical diameter-enlarged portion 31 and a cylindrical engagement integrally disposed with the enlarged-diameter portion 31 on one end side in the axial direction of the enlarged-diameter portion 31. Part 32, tapered part 34 which is integrally disposed on the end surface of locking part 32 opposite to the diameter-expanding part 31 side, and whose inner peripheral surface is gradually reduced in diameter, and locking part of tapered part 34 It has a reduced diameter portion 33 that is integrally disposed on the end surface opposite to the 32 side.

ここで、拡径部３１は、ベッセル４０の内径に略等しい外径Ｄ5と、セラミックろ過膜１０の外径およびセラミックろ過膜１０の端部外周面に配置されるシール材としてのゴムパッキン６０の厚みの和に略等しい内径Ｄ4とを有する。そして、拡径部３１の内周面には、連結ろ過体の両端に位置するセラミックろ過膜１０がゴムパッキン６０を介して挿入される。即ち、拡径部３１には、セラミックろ過体１０の端部が嵌合する。また、拡径部３１の外周面は、端部固定部材３０をベッセル４０内に固定した際に、ベッセル４０の内周面と嵌合する。 Here, the enlarged diameter portion 31 has an outer diameter D 5 substantially equal to the inner diameter of the vessel 40, an outer diameter of the ceramic filtration membrane 10, and a rubber packing 60 as a sealing material disposed on the outer peripheral surface of the end portion of the ceramic filtration membrane 10. And an inner diameter D 4 that is substantially equal to the sum of the thicknesses. And the ceramic filtration membrane 10 located in the both ends of a connection filter body is inserted in the internal peripheral surface of the enlarged diameter part 31 via the rubber packing 60. FIG. That is, the end portion of the ceramic filter body 10 is fitted into the enlarged diameter portion 31. Further, the outer peripheral surface of the enlarged diameter portion 31 is fitted with the inner peripheral surface of the vessel 40 when the end fixing member 30 is fixed in the vessel 40.

なお、拡径部３１の係止部３２側とは反対側の端面の一部には、ろ過体連結部材２０の爪部２３と同様の形状を有する爪部３５が配設されている。従って、この端部固定部材３０では、上述したろ過体連結部材２０と同様にして、連結ろ過体を横置き或いは斜め置きした状態で固定する場合であっても、連結ろ過体の大きな荷重を爪部３５でも支持することができる。従って、連結ろ過体の荷重によりゴムパッキン６０が拡径部３１の内周面側で局所的に潰れるのを抑制し、拡径部３１の内周面のシール面圧を均一化することができる。そのため、端部固定部材３０では、固定部分をより確実にシールすることができると共に、ゴムパッキン６０が局所的に潰れて劣化するのを抑制することができる。また、爪部３５には傾斜面３６が形成されているので、端部固定部材３０は、傾斜面３６を利用して連結ろ過体の端部へ容易に取り付けることができる。   A claw portion 35 having the same shape as the claw portion 23 of the filter body connecting member 20 is disposed on a part of the end surface of the enlarged diameter portion 31 opposite to the locking portion 32 side. Therefore, in this end fixing member 30, even when the connected filter body is fixed horizontally or obliquely in the same manner as the filter body connecting member 20 described above, a large load of the connected filter body is clawed. The portion 35 can also be supported. Therefore, it is possible to suppress the rubber packing 60 from being locally crushed on the inner peripheral surface side of the enlarged diameter portion 31 due to the load of the connected filter body, and to equalize the seal surface pressure on the inner peripheral surface of the enlarged diameter portion 31. . Therefore, in the end fixing member 30, the fixing portion can be more reliably sealed, and the rubber packing 60 can be prevented from being locally crushed and deteriorated. Moreover, since the inclined surface 36 is formed in the nail | claw part 35, the edge part fixing member 30 can be easily attached to the edge part of a connection filter body using the inclined surface 36. FIG.

また、図１および図３（ｅ）に示すように、係止部３２は、拡径部３１の内径Ｄ4よりも小さい内径Ｄ6を有している。また、係止部３２は、拡径部３１と外径が等しく、且つ、拡径部３１と同軸に配設されている。そして、係止部３２には、連結ろ過体の両端に位置するセラミックろ過膜１０の端面が、シール材としてのゴムパッキン６０を介して液密に係止される。即ち、係止部３２の内径Ｄ6と拡径部３１の内径Ｄ4との差により形成される段差部分に、セラミックろ過膜１０の端面の外周縁部がゴムパッキン６０を介して係止される。 Moreover, as shown in FIG. 1 and FIG. 3 (e), the locking portion 32 has an inner diameter D 6 that is smaller than the inner diameter D 4 of the enlarged diameter portion 31. The engaging portion 32 has the same outer diameter as the enlarged diameter portion 31 and is disposed coaxially with the enlarged diameter portion 31. And the end surface of the ceramic filtration membrane 10 located in the both ends of a connection filter body is liquid-tightly locked by the latching | locking part 32 via the rubber packing 60 as a sealing material. That is, the outer peripheral edge portion of the end surface of the ceramic filtration membrane 10 is locked via the rubber packing 60 at the step portion formed by the difference between the inner diameter D 6 of the locking portion 32 and the inner diameter D 4 of the expanded diameter portion 31. The

テーパー部３４を介して係止部３２と一体的に連結された縮径部３３は、係止部３２の内径Ｄ6よりも小さい内径Ｄ7と、係止部３２の外径Ｄ5よりも小さい外径Ｄ8とを有する。そして、図１に示すように、縮径部３３の外周面には、ベッセル４０の内周面に形成された環状溝４２と嵌合して端部固定部材３０をベッセル内に固定するリング部材８０が配設される。なお、リング部材８０としては、特に限定されることなく、スナップリング等を用いることができる。 The reduced diameter portion 33 integrally connected to the locking portion 32 via the tapered portion 34 has an inner diameter D 7 smaller than the inner diameter D 6 of the locking portion 32 and an outer diameter D 5 of the locking portion 32. and a small outer diameter D 8. As shown in FIG. 1, the ring member that fits the annular groove 42 formed on the inner peripheral surface of the vessel 40 on the outer peripheral surface of the reduced diameter portion 33 and fixes the end fixing member 30 in the vessel. 80 is disposed. The ring member 80 is not particularly limited, and a snap ring or the like can be used.

また、図１に示すように、テーパー部３４は、内部空間が係止部３２側から縮径部３３側に向かって次第に縮径している。即ち、テーパー部３４の内部空間は、裁頭円錐形状をしている。更に、テーパー部３４の外周面には、Ｏリング７０を設置するための環状溝３７が形成されている。   Further, as shown in FIG. 1, the tapered portion 34 has its inner space gradually reduced in diameter from the locking portion 32 side toward the reduced diameter portion 33 side. That is, the internal space of the tapered portion 34 has a truncated cone shape. Further, an annular groove 37 for installing the O-ring 70 is formed on the outer peripheral surface of the tapered portion 34.

そして、この端部固定部材３０は、テーパー部３４の外周面に形成された環状溝３７にＯリング７０を設置した状態で連結ろ過体の両端部のそれぞれに取り付けられ、リング部材８０によりベッセル４０に容易に固定される。即ち、ベッセル４０の内周面と連結ろ過体の外周面との間に形成された空間５０は、Ｏリング７０を配置した端部固定部材３０により液密に封止される。   The end fixing member 30 is attached to each of both ends of the coupled filter body with the O-ring 70 installed in the annular groove 37 formed on the outer peripheral surface of the tapered portion 34, and the vessel 40 is connected by the ring member 80. Easily fixed to. That is, the space 50 formed between the inner peripheral surface of the vessel 40 and the outer peripheral surface of the connected filter body is liquid-tightly sealed by the end fixing member 30 in which the O-ring 70 is disposed.

ここで、連結ろ過体の端部に取り付けられた端部固定部材３０の内側の空間は、被処理水のろ過時にベッセル４０外からセラミックろ過膜１０の貫通孔１１に被処理水を供給する第１の流路を形成する。なお、この第１の流路は、連結ろ過体を逆洗する際には、セラミックろ過膜１０の貫通孔１１からベッセル４０の外へと逆洗排水を排出する流出口として機能する。因みに、この端部固定部材３０では、拡径部３１とテーパー部３４との間に円筒状の係止部３２が位置しているので、連結ろ過体の端面とテーパー部３４の内周面との間に所定長さの空間が存在している。従って、係止部３２を設けることなく拡径部３１とテーパー部３４とを隣接配置した場合と比較して、テーパー部３４の内周面が逆洗排水の流れの抵抗になり難く、逆洗時に逆洗排水を良好に流すことができる。   Here, the space inside the end fixing member 30 attached to the end of the coupled filter body supplies the treated water from the outside of the vessel 40 to the through hole 11 of the ceramic filtration membrane 10 when the treated water is filtered. 1 flow path is formed. In addition, this 1st flow path functions as an outlet which discharges backwash drainage from the through-hole 11 of the ceramic filtration membrane 10 to the outside of the vessel 40 when backwashing the connected filter body. Incidentally, in this end fixing member 30, since the cylindrical locking portion 32 is located between the enlarged diameter portion 31 and the tapered portion 34, the end surface of the coupled filter body and the inner peripheral surface of the tapered portion 34 A space of a predetermined length exists between the two. Therefore, compared with the case where the enlarged diameter portion 31 and the tapered portion 34 are disposed adjacent to each other without providing the locking portion 32, the inner peripheral surface of the tapered portion 34 is less likely to be a resistance to the flow of backwash drainage, and backwashing is performed. Sometimes the backwash drainage can flow well.

そして、このようなろ過モジュール１００によれば、一つのベッセル４０内に収納するセラミックろ過膜１０の全長を長くして、コストを削減することができる。即ち、セラミックろ過膜１０ごとにベッセル４０を準備する場合と比較して、使用するベッセル４０等の数を低減し、コストを削減することができる。なお、このろ過モジュール１００では、上記ろ過体連結部材２０を用いているので、セラミックろ過膜１０の荷重を支持しつつ連結部分を確実にシールすることができると共に、連結ろ過体の外周面とハウジングの内周面との間に水等の液体を流すことができる。従って、通常のろ過操作および逆洗操作に支障は生じない。   And according to such a filtration module 100, the full length of the ceramic filtration membrane 10 accommodated in one vessel 40 can be lengthened, and cost can be reduced. That is, compared with the case where the vessel 40 is prepared for each ceramic filtration membrane 10, the number of the vessels 40 to be used can be reduced and the cost can be reduced. In addition, in this filtration module 100, since the said filter body connection member 20 is used, while supporting the load of the ceramic filtration membrane 10, while being able to seal a connection part reliably, the outer peripheral surface and housing of a connection filter body A liquid such as water can be allowed to flow between the inner peripheral surface and the inner peripheral surface. Therefore, there is no problem in normal filtration operation and backwash operation.

因みに、ベッセル４０内への連結ろ過体の収容および固定は、特に限定されることなく、例えば以下のようにして実施することができる。   Incidentally, accommodation and fixation of the connection filter body in the vessel 40 are not particularly limited, and can be performed as follows, for example.

まず、セラミックろ過膜１０の一端にゴムパッキン６０を介して端部固定部材３０を取り付ける。次に、一端に端部固定部材３０を取り付けたセラミックろ過膜１０に対し、ろ過体連結部材２０およびゴムパッキン６０を用いて所望の本数のセラミックろ過膜を連結して、一端に端部固定部材３０が取り付けられた連結ろ過体を構成する。その後、連結ろ過体の他端にパッキン６０を介して端部固定部材３０を取り付ける。そして、両端に端部固定部材３０を取り付けた連結ろ過体を、端部固定部材３０にＯリング７０を取り付けた状態でベッセル４０内に圧入する。そして最後に、連結ろ過体を内部に収容したベッセル４０の両端からリング部材８０を圧入して、端部固定部材３０および連結ろ過体をベッセル４０に固定する。   First, the end fixing member 30 is attached to one end of the ceramic filtration membrane 10 via the rubber packing 60. Next, a desired number of ceramic filtration membranes are connected to the ceramic filtration membrane 10 having the end fixing member 30 attached to one end using the filter connecting member 20 and the rubber packing 60, and the end fixing member is attached to one end. The connection filter body 30 is attached. Thereafter, the end fixing member 30 is attached to the other end of the coupled filter body via the packing 60. And the connection filter body which attached the edge part fixing member 30 to both ends is press-fitted in the vessel 40 in the state which attached the O ring 70 to the edge part fixing member 30. FIG. Finally, the ring member 80 is press-fitted from both ends of the vessel 40 in which the connected filter body is accommodated, and the end fixing member 30 and the connected filter body are fixed to the vessel 40.

以上、図面を参照して本発明の実施形態を説明したが、本発明のろ過体連結部材およびろ過モジュールは上述した一例に限定されることは無く、適宜変更を加えることができる。   As mentioned above, although embodiment of this invention was described with reference to drawings, the filter body connection member and filtration module of this invention are not limited to the example mentioned above, A change can be added suitably.

本発明によれば、ろ過体の荷重を支持しつつ連結部分を確実にシールすることを可能にし、且つ、連結したろ過体の周囲を水等の液体が流れることを可能にしたろ過体連結部材を提供することができる。また、該ろ過体連結部材を用いて連結したろ過体をハウジング内に収容してなるろ過モジュールを提供することができる。   According to the present invention, it is possible to reliably seal the connecting portion while supporting the load of the filter body, and to allow a liquid such as water to flow around the connected filter body. Can be provided. Moreover, the filtration module which accommodates the filter body connected using this filter body connection member in a housing can be provided.
