り、問題となる。Problems to be Solved by the Invention This reliable filtration unit is assembled at room temperature and manufactured into a product, and then installed in a processing liquid tank. However, if necessary, the mixed solution to be treated is
For example, since the temperature is 30 to 35°C or 55 to 60°C, when the filtration unit is immersed in this liquid, the temperature of the filtration unit is raised to the temperature of the liquid. However, there is a difference in thermal expansion coefficient between the plastic guide plate 10 and the ceramic membrane 1 that make up this unit, and since the guide plate 10 stretches better, a large tensile stress is generated in the longitudinal direction of the ceramic membrane 1. This may cause damage to the ceramic film l, which poses a problem.
そこで本発明はこのような問題を解決し、温度変化に際

である。Means for Solving the Problems In order to achieve all of the above objects, the present invention attaches headers to both ends of a plurality of tubular external pressure type membranes, and passes a guide plate between both headers to connect the headers and guide plates to each other. In the connected filtration unit, one end of the external pressure membrane and one header are fixed with an adhesive, the adhesive is filled between the other ends of the external pressure membrane and cured, and the other end of the external pressure membrane is fixed. Means is provided between the side-cured adhesive and the other header to allow the cured adhesive and the other header to move away from each other in the length direction of the external pressure membrane.

自由に伸縮可能となり、両者間の熱膨張率に差があって

い。Effect: According to such a configuration, on the other end side of the external pressure type membrane,
Since this external pressure type membrane and the other header connected to the guide plate are edged, the external pressure type membrane and the guide plate can freely expand and contract with each other, and even if there is a difference in the coefficient of thermal expansion between them, the external pressure type membrane and the guide plate can be freely expanded and contracted. No tensile stress that causes breakage acts on the mold membrane.

ラミック膜１の長さ方向に離れることを許容する。In FIG. 1, a space 12 is formed between the inner surface of the recess 8 of the header 3 and the cured adhesive 9. This space 12 is formed when the main unit is assembled, or by applying a release agent to the recess 8 before filling the recess 8 with the adhesive 9, and the adhesive 9 before hardening is formed. This prevents the adhesive 9 from adhering to the inner surface of the recess 8 and allows the cured adhesive 9 to freely separate from the inner surface of the recess 8 in the length direction of the ceramic film 1 as an external pressure type film.

ク膜１が破壊するなどの事故の発生が防止される。According to such a configuration, even if the temperature of the liquid to be treated around the filtration unit increases, the plastic guide plate 10, which has a higher coefficient of thermal expansion than the ceramic membrane l, remains free as shown in FIG. Therefore, no tensile stress is applied to the ceramic membrane 1. Therefore, accidents such as destruction of the ceramic film 1 are prevented from occurring.

な事態の発生を防止できる。Effects of the Invention As described above, according to the present invention, the header connected to the guide plate and the adhesive connected to the external pressure type membrane are configured so that they can be separated from each other in the length direction of the external pressure type membrane. Therefore, even if the guide plate expands due to temperature rise, a situation in which large tensile stress acts on the external pressure type membrane and causes the external pressure type membrane to break can be prevented from occurring.
