Quick drying apparatus of hollow fiber film

Abstract

The invention relates to a process for manufacturing hollow fiber separating films by employing vacuum or air blowing, wherein a batch quantity of hollow fiber separating films can be dried rapidly in the drying apparatus, therefore facilitating the scale production of the hollow fiber separating films.

Description

Technical field: [0001] The present invention relates to the field of manufacture of hollow fiber separation membranes. Specifically, a batch of hollow fiber separation membranes is rapidly dried in the drying equipment of the present invention by vacuum or air blowing. It is one of the necessary equipment for large-scale production of hollow fiber separation membranes. Background technique: [0002] Hollow fiber membrane is a high-tech product, which is more and more widely used in various fields of medicine, food, environmental protection and daily life. It needs to be cleaned and dried before being assembled into various separation devices. Especially when polyurethane is used for encapsulation, because polyurethane is easy to react with water to produce air bubbles, which will cause leakage of separation equipment, so it is necessary to ensure that the hollow fiber membrane is absolutely dry to ensure the success of encapsulation. At present, the most commonly used dr...

AI Technical Summary

Problems solved by technology

At present, the most commonly used drying method is to place the hollow fiber membrane in a specific temperature and humidity environment, hang it up, and let it dry naturally, so it takes a long time and takes up a lot of space, especially for the drying of hollow fiber separation membranes used as medical equipment. The process must be carried out in a clean workshop, resulting in a substantial inc
