に中空糸膜の束を固定する役割を有する。In hollow fiber membrane modules used in these fields, the potting resin fixing part of the hollow fiber membrane liquid-tightly or airtightly partitions the area in contact with the outer wall surface of the fixed hollow fiber membrane and the area communicating with the hollow part. , has the role of fixing a bundle of hollow fiber membranes within a cylindrical case.

中空糸膜束の乱れを防止できるという利点を有する遠心
法による固定方法が利用されている。For fixing the hollow fiber membrane bundle to the cylindrical case with resin, the centrifugal method has the advantage of being able to densely fill the resin between each hollow fiber and preventing the hollow fiber membrane bundle from being disturbed during the fixing process. A fixing method is used.
この遠心法は、以下のような操作によって中空糸膜束の
固定を行うものである。In this centrifugation method, a hollow fiber membrane bundle is fixed by the following operations.
ます、多数の中空糸膜を固定すべき端部を揃えて集束し
て形成した中空糸膜束を、筒状ケース内に、中空糸膜束
の固定すべき端部が筒状ケースの開口端部内に位置する
ように収納する。次に、この開口端部に固定処理用の治
具をセットし、筒状ケースの開口端部内壁と治具によっ
て樹脂固定部形成用の領域を得る。First, a hollow fiber membrane bundle formed by aligning and converging the ends of a large number of hollow fiber membranes to be fixed is placed in a cylindrical case, with the end of the hollow fiber membrane bundle to be fixed aligned with the open end of the cylindrical case. Store it so that it is located inside the room. Next, a fixing jig is set at this open end, and a region for forming a resin fixing part is obtained by the inner wall of the open end of the cylindrical case and the jig.

いる樹脂固定部形成用の領域に樹脂を注入、充填し樹脂
固定部を形成する。すなわち、遠心力は筒状ケースの開
口端部の開口方向に作用する。In this state, set the cylindrical case in the centrifugal injector, and move the circular orbit around the rotation center on a straight line passing through the central axis of the cylindrical case to the open end of the cylindrical case, that is, the end of the hollow fiber membrane bundle. The resin is fixed using the centrifugal force generated by rotating the cylindrical case so that the part to be fixed with the resin is drawn and the main body of the cylindrical case is located closer to the center of rotation than the open end of the cylindrical case. A resin fixing portion is formed by injecting and filling the resin fixing portion forming region where the end portion of the hollow fiber membrane bundle to be processed is placed. That is, the centrifugal force acts in the opening direction of the open end of the cylindrical case.
なお、筒状ケースの樹脂固定部が形成された部分の所定

空糸膜モジュールを得ることができる。In addition, the resin fixing part of the cylindrical case is cut at a predetermined position on a plane perpendicular to the central axis to form a surface where each hollow fiber membrane opens, and this is used to fabricate a filter, etc. A hollow fiber membrane module for use can be obtained.
［発明が解決しようとする課題］
従来の遠心法を用いた中空糸膜束の固定では、樹脂固定
部の表面が、筒状ケースの樹脂固定部が形成される開口
端部が描く円軌道に対応した曲率の曲面として形成され

径が小さい程、また筒状ケースの径が大きい程顕著に現
われてくる。[Problems to be Solved by the Invention] In fixing a hollow fiber membrane bundle using the conventional centrifugation method, the surface of the resin fixing part is not aligned with the circular orbit drawn by the open end of the cylindrical case where the resin fixing part is formed. It is formed as a curved surface with a corresponding curvature. Moreover, this phenomenon becomes more pronounced as the radius of the circular orbit through which the open end passes becomes smaller, and as the diameter of the cylindrical case becomes larger.
このように、樹脂固定部表面が曲面として形成されると
、樹脂固定部の厚さが筒状ケースの中心軸で薄く、周壁
付近で厚く不均一となり、その耐圧性が低下するという
問題を生じ、５０℃以上の熱水を処理する場合や、中空

This becomes more noticeable when hot water of 50° C. or higher is treated or when the hollow fiber membrane module becomes larger (when the diameter of the cylindrical case becomes larger).

が困難となる場合もある。In addition, if the surface of the resin fixing part is formed as a curved surface, the effective membrane area (area of the part not embedded in the resin fixing part) of each hollow fiber membrane will be different, and the hollow fiber membrane module as a whole will not be as designed. In some cases, it may be difficult to obtain effective membrane area.
更に、透明な筒状ケースを用いた場合、中空糸膜モジュ
ールの外観を損なうことにもなる。Furthermore, if a transparent cylindrical case is used, the appearance of the hollow fiber membrane module will be impaired.

An object of the present invention is to provide a method for fixing a hollow fiber membrane bundle using a centrifugation method, which allows formation of a hollow fiber membrane bundle as a flat surface.

The resin fixing part is formed by applying centrifugal force in the opening direction of the open end of the cylindrical case. In a method for fixing a hollow fiber membrane bundle, the resin is injected into a region for use and solidified to form a resin fixing part for fixing the end of the hollow fiber membrane bundle.

するように、樹脂の注入を行う。In this state, the cylindrical case 1 is set in a centrifugal injector, and the cylindrical case 1 is rotated with the point A on the central axis of the cylindrical case 1 as the center of rotation. The resin is injected and filled into the molding space of the resin fixing part 3.3'' through the resin injection hole 8.8' using centrifugal force acting in the opening direction of the open end of the cylindrical case 1. At this time, while the injected resin has fluidity, the resin is injected so that it overflows from the overflow hole 4.4° into the resin receiver 7.7'.

As the amount of injection increases, it moves toward the center of rotation and reaches the position where the overflow hole 4.4' is provided. At that time, the liquid level of the injected resin would form curved surfaces with curvatures indicated by B-B and B'-B' if there were no overflow holes, but due to the overflow of the resin from these overflow holes, B-B and B The lowest liquid level of the curved surface at the curvature indicated by '-B', i.e. C-C and c'-c
