製造する方法全提供するものである。4' is the pipe joint for the inlet and outlet of the stock solution, and the cylindrical case 2'
When separating a liquid using the above device, the stock liquid is supplied from the A side. ,
The obtained permeate is discharged from the permeate outlet 5', and the concentrated liquid is discharged from the B side. In this case, the stock solution and concentrated liquid must not leak to the permeate side, and if leakage occurs, the performance of the separation device will deteriorate and become unusable. Therefore, in the production of fluid separation devices, hollow fibrous membranes It is extremely important to bond the molding resin and the cylindrical case to the molding resin in a liquid-tight manner.
In the conventional method of injecting 4 resin and fixing both ends of the hollow fibrous membrane to the thY dog case by centrifugal casting, the pressure generated by centrifugal force causes the casting resin to bond to the hollow fibers inside the cylindrical case. As a result, the hollow fibrous membrane may come into contact with the inner surface of the cylindrical case, or the hollow fibrous membranes may come into close contact with each other, making it difficult to fill the casting resin in these areas, which may cause the hollow fibrous membrane to touch the inner surface of the cylindrical case. Problems such as poor adhesion with the casting resin and poor impregnation of the hollow fibrous membrane with the casting resin occur, and it is actually extremely difficult to achieve the above-mentioned adhesion completely. 〇The present invention has been made to solve the drawbacks of the prior art, and by filling the casting resin as evenly as possible from the periphery of the hollow fibrous membrane bundle, leakage can be prevented. The present invention provides a complete method for manufacturing an extremely reliable fluid separation device.

ある。That is, the present invention provides a method for manufacturing a fluid separation device in which a large number of hollow fibrous membranes are bundled in parallel, stored in a cylindrical booth, and both ends of the membrane are fixed to the cylindrical case with casting resin by centrifugal casting. A groove is provided on the inner surface of the cylindrical case along the circumferential direction so as to communicate with a resin injection port, and casting resin is injected through the resin injection port and the casting resin is passed through the groove. The present invention relates to a method for manufacturing a fluid separation device, characterized in that the hollow fiber membrane bundle is filled from around the periphery of the hollow fibrous membrane bundle.

うに設けられている。Hereinafter, an example of the present invention will be explained with reference to the drawings. Both ends of the cylindrical leak 2 are housed in a concave shape projecting from the end Ini of the cylindrical leak 2. A casting jig 3 is detachably attached to the end of the cylindrical leak 2 via a gasket 4. The casting jig 3 is engaged with the placket 5 of the turntable.Resin injection ports 6 are provided near both ends of the cylindrical case 2, and the cylindrical A groove 7 is provided on the inner surface of the shaped case 2 along the circumferential direction so as to communicate with the upper resin injection port 6.

Next, a predetermined amount of casting resin 9 is supplied in the same manner and centrifugal casting is performed. Supplied casting resin '9
1d, the hollow groove 7 is first filled, and then, by the action of centrifugal force, it sequentially flows from the periphery of the hollow fibrous membrane aggregate to both ends, and is uniformly filled. When supplying the casting resin, it is preferable to supply the casting resin for a predetermined ridge in several portions in order to avoid heat generation as much as possible. By solidifying the filled casting resin 9, both ends of the hollow fibrous membrane 1 are fixed to the m-shaped case 2.
