Description of the Related Art A hollow fiber membrane module is known as one type of membrane module for separating and purifying liquids using a microfiltration membrane or an ultrafiltration membrane. In the membrane module, it is indispensable to separate the raw solution side and the filtrate side with the membrane as a boundary and to apply a predetermined transmembrane pressure difference to the membrane. Thus, in a hollow fiber membrane module, usually, a hollow fiber membrane bundle is inserted into a cylindrical case, and a partition is formed by injecting a resin into the inner end of the cylindrical case. A chamber communicating with the hollow fiber membrane and a chamber surrounding the hollow fiber membrane bundle are divided with the partition wall as a boundary, and one chamber is used as a stock solution chamber and the other chamber is used as a filtrate chamber. For example, in the external pressure type hollow fiber membrane module, the chamber surrounding the hollow fiber membrane bundle is the stock solution chamber, and the chamber communicating with the hollow fiber membrane is the filtrate chamber. The chamber communicating with the hollow fiber membrane is used as a stock solution chamber, and the chamber surrounding the hollow fiber membrane bundle is used as a filtrate chamber.

ある。By the way, an external pressure type hollow fiber membrane module, for example, a hollow fiber membrane bundle is inserted into a cylindrical case, and partition walls are formed by injecting resin into both ends of the cylindrical case. Each end of the hollow fiber membrane is opened to the outer surface of each resin partition wall, the space surrounded by the cylindrical case and both resin partition walls is the stock solution chamber, the inside of the hollow fiber membrane is the filtrate side, and the stock solution is stored in the stock solution chamber. In the hollow fiber membrane module in which the undiluted solution is filtered through a hollow fiber membrane and the filtered solution is taken out from both ends of the hollow fiber membrane, the undiluted solution is evenly fed to the center of the hollow fiber membrane bundle. It is difficult to remove air from the central portion of the hollow fiber membrane bundle, and a substantial reduction in membrane area is likely to occur, which is a disadvantage in processing efficiency.

ではない。Further, in the membrane module, a decrease in filtration flux with time due to attachment / deposition of a gel layer or a cake layer on the membrane surface is unavoidable, and therefore, the membrane is regularly washed. It is necessary to recover the filtration flux by
In the hollow fiber membrane module, it is difficult to sufficiently infiltrate the cleaning liquid into the central portion of the hollow fiber membrane bundle, and efficient cleaning is not easy.

It is known to form a gap between the small bundles (for example, JP-A-2-203924 and JP-A-3-

It is necessary to set the material, and the production efficiency is unavoidably reduced due to the addition of extra steps and the accompanying complication of the steps in manufacturing the hollow fiber membrane module. Further, depending on the stock solution to be filtered, contamination by components eluted from the net or the like also poses a problem (for example, in the fields of semiconductors and pharmaceuticals), and as a result of the restriction of the net material, high cost may be brought about.

することが妥当である。In the present invention, the injection of the resin is performed by measuring the amount of the resin and injecting the measuring resin at a high speed so that the injection resin does not block the stock solution flow port of the header. The hollow fiber membrane bundle is divided into a plurality of small bundles according to the injection pattern by the flow of the high-speed injection resin. In this case, if the filling rate of the hollow fiber membrane in the tubular case is too high, the division becomes difficult, so the filling rate is 75% or less,
It is preferably 60% or less. However, if the filling rate is too low, the characteristics of the wide membrane area per unit volume of the hollow fiber membrane module will decline, so it is appropriate to set the filling rate to 40% or more.

After inserting the hollow fiber membrane bundle, the case body 11 having the header materials 120 fixed at both ends is fixed on the rotary table 5, and each header-
For the material 120, the case body 11 is more than the header material.
The resin tank 6 disposed on the center side of the header member is connected to the side surface hole 4 of the header material by a communication pipe 61, and each resin tank 5 is fixed to the turntable 5 or the case body 11, and then the turntable 5 is fixed. It is possible to use a method of rotating and injecting the measured resin in each resin tank 6 into each header-material 120 from the side surface hole 4 by its rotational centrifugal force. The detour is eliminated so that it goes against the flow. According to this method, the resin partition walls on both ends of the case can be simultaneously molded.

造できる。Since the resin partition wall is formed by injecting the resin through the hole on the side surface of the inner end of the cylindrical case, the hollow fiber membrane is divided into small bundles according to the pattern of the flow of the injected resin. A gap is formed between the small bundles. In this small bundle of hollow fiber membranes, since the outer diameter is small, it is possible to supply the undiluted solution to the center of the small bundle sufficiently uniformly through the gaps around the hollow fiber membrane. A hollow fiber membrane module that can be well penetrated into the center and is excellent in separation treatment efficiency and washing efficiency can be manufactured.
