Problems solved by technology
Therefore, the pouring resin in the nozzle is easy to clog, and the discharge amount is also limited. In addition, the hollow fiber membrane sheet is damaged due to contact with the tip of the nozzle.
In addition, if the injection of such casting resin is to be automated mechanically, the position of the nozzle must be controlled multi-axis with high precision. Therefore, a combination of multi-axis robots and sensors is required on both sides of the hollow fiber membrane. Initially, soaring costs

Abstract
The present invention provides a process and apparatus for manufacturing a hollow fiber membrane module, which can easily inject the potting resin without expanding the opening of the collecting waterpipe, can prevent the damage of the hollow fiber membrane sheet form due to the contact of the nozzle, and can easily perform mechanical automation injection operation. A method for manufacturing a hollow fiber membrane module including a hollow fiber membrane sheet material (10) and a collecting pipe (12b) includes an injection process: the end of the hollow fiber membrane sheet material (10) isfixed by a collecting pipe (12b), the liquid potting resin P is injected from the nozzle (50) into the collecting pipe (12b) and hardened so that the sheet surface (10a) of the hollow fiber membranesheet material (10) is inclined relative to the vertical direction through a maintaining device (110), and the hollow fiber membranes are fixed to each other in the receiving portion in the collectingpipe (12b) of the hollow fiber membrane module (10).
Description
technical field [0001] The present invention relates to a manufacturing method and a manufacturing device of a hollow fiber membrane module. Background technique [0002] As a hollow fiber membrane module for producing sterile water, drinking water, high-purity water, etc., a hollow fiber membrane in which a water collection pipe is provided at the end of a hollow fiber membrane sheet in which a plurality of hollow fiber membranes are aligned into a sheet is known. Membrane modules (Patent Documents 1 and 2). [0003] As a method for producing such a hollow fiber membrane module, the following methods may be mentioned, for example. The end of the hollow fiber membrane sheet is inserted into a water collecting pipe with an opening formed at one end, and in the state of standing upright in the vertical direction, from the sheet surface sides of the two ends of the hollow fiber membrane sheet to the A liquid casting resin (potting solution) is injected into the water collecti...
