この考案はモジユール構造体に関し、詳しくは
中空繊維束の固定構造を改良したモジユール構造
体に関する。[Detailed description of the invention] (a) Purpose of the invention [Field of industrial application] This invention relates to a modular structure, and more specifically to a modular structure with an improved fixing structure for hollow fiber bundles.
一般にモジユール構造体は、円筒状容器内に、

Generally, a modular structure has a cylindrical container with
The hollow fiber bundle is fixed by a sealing part made of an adhesive formed at one end or both ends in the container, and permeates the liquid to be treated.

ることがある。
Conventionally, epoxy resin-based or urethane resin-based adhesives have been used as adhesives, but the shrinkage of the adhesive that occurs during curing causes the bond between the sealing part, the inner wall surface of the container, and the hollow fiber bundle. Stress that tends to cause the joint to separate is accumulated in the joint. Therefore, the bonded portion, particularly the bonded portion between the sealing portion and the inner surface of the container, may easily peel off due to external stress such as pressure history or temperature change that occurs during permeation treatment of the liquid to be treated.
この対策として、接着剤の硬化収縮率及び引張

なり容器の製作費が高価に付く不都合があつた。 As a countermeasure to this problem, attempts have been made to reduce the curing shrinkage rate and tensile modulus of the adhesive, but it has still not been possible to completely prevent the above-mentioned peeling. Furthermore, as disclosed in Japanese Patent Application Laid-open No. 53-102878, for example, measures have been taken to improve the fixing strength of the hollow fiber bundle by providing a recessed portion in the inner wall surface of the casing where the sealing portion is formed. With this countermeasure, when the adhesive (sealant) that forms the sealing part hardens, its shrinkage is restrained by the recess, so the sealing part is pulled toward the cylindrical wall of the container, causing the sealing part to tighten. Moreover, when the container is injection molded, a mold is required to form the concave portion, which increases the manufacturing cost of the container.
この考案は以上の事情に鑑みなされたもので、

ることにある。 This idea was made in view of the above circumstances,
The main purpose is to improve the peeling resistance of the joint between the sealing part, the inner wall of the container, and the hollow fiber bundle by forming the sealing part to sandwich the end of the cylindrical wall of the container from its inner and outer wall surfaces. This prevents the joints from peeling off even if subjected to external stresses such as pressure history and temperature changes during permeation treatment of the liquid to be treated, and also prevents cracks from occurring in the sealing part, and the container is injection molded. The objective is to be able to manufacture containers at low cost.

It extends outside the container in a direction opposite to the center of the cylinder axis of the container.

This invention will be explained in detail below based on the embodiments shown in the figures. Note that this invention is not limited to this.

２外に排出される。 In FIG. 1, a modular structure 1 has a hollow fiber bundle 3 fixed in a cylindrical container (casing) 2 with sealing parts 4, 4 made of adhesive formed at both ends of the casing 2, and covered. It permeates the treatment liquid. This permeation treatment is performed by opening holes 7 provided in caps 6, 6, which cover both ends of the casing 2 through O-rings 5, 5 in a liquid-tight manner.
The process is carried out by supplying the liquid to be treated into the hollow part of the hollow fiber bundle 3 from one side of the cap hole 7. , 7 are discharged from the casing 2 from the other side.
前記封止部４は、各封止部４形成部位における

全面まで連続して延出されている。 The sealing portions 4 extend continuously from both end surfaces of the casing 2 to the entire surface of the outer wall near both ends so as to tightly cover the cylindrical wall of the casing 2 at each sealing portion 4 formation site.
次に、第２図に基づいてこの封止部４形成方法

造及び寸法の選定が可能となる。 First, temporary caps 9 are screwed onto both ends of the casing 2. Then, a space with a predetermined interval is formed between both end faces of the casing 2 and the temporary cap 9. Note that the inner surface of the temporary cap 9 is formed so that the sealant is difficult to adhere to. Therefore, an adhesive is injected into the space to seal the gaps between the hollow fiber bundles 3 and the gap between the hollow fiber bundles 3 and the inner wall surface of the casing 2. Cover the outer wall surface with adhesive. After the adhesive has hardened, the temporary cap 9 is removed and cut along the dotted line X in FIG. 2 to form the sealing part 4. At this time, by widening and smoothing A in FIG. 2, when assembling the casing 2 and the cap hole 7, it is possible to select a wider packing structure and dimensions without being restricted by the dimensions of the end face of the casing 2. It becomes possible.

ーシング２の内壁面によつて、封止部４の収縮・
膨張をそれぞれ防止する。 As described above, since the sealing part 4 has a structure that wraps around both ends of the casing 2, the shrinkage force when the sealant hardens and the thermal expansion between the sealant and the casing 2 during the permeation treatment of the liquid to be treated. difference in coefficients,
Due to temperature and pressure differences between the sealing part 4 and the casing 2 due to rapid temperature changes, stress that causes interfacial failure (peeling) is applied to the joint between the sealing part 4 and the casing 2. Also, peeling of the joint can be prevented. That is, for example, the sealing part 4
The outer wall surface of the casing 2 handles the stress that causes the sealing part 4 to contract, and the inner wall surface of the casing 2 handles the stress that causes the sealing part 4 to expand.
Prevent expansion respectively.

発生することを防止できる。 Moreover, since the casing 2 does not have grooves, recesses, etc. on its inner wall surface, the casing 2 can be manufactured easily and inexpensively. Furthermore, since the sealing part 4 is not restrained by the above-mentioned grooves, recesses, etc., it can shrink and move in the direction of the cylinder axis of the casing 2 when it hardens, thus preventing the occurrence of cracks in the sealing part 4. It can be prevented.

b. With these,
The resistance to peeling on the outer peripheral wall side can be improved more than in the first embodiment. Incidentally, the threaded portion 10b in FIG. 3b can also be used as a male thread for the temporary cap 9.

It is possible to prevent the container from peeling off and to prevent cracks from occurring in the sealing portion, and furthermore, when the container is injection molded, the container can be manufactured at a low cost.
