Description

Technical Field

[0001] This utility model relates to the field of aluminum electrolytic membrane technology, and in particular to a membrane processing and drying device. Background Technology

[0002] The battery separator is a membrane material placed between the positive and negative electrodes of a battery. It is a very critical part of the battery and has a direct impact on battery safety and cost. Its main functions are to isolate the positive and negative electrodes and prevent electrons in the battery from passing through freely, while allowing ions in the electrolyte to pass freely between the positive and negative electrodes.

[0003] The existing Chinese utility model patent with publication number CN220594146U discloses a heat treatment device for a microporous diaphragm, relating to the field of microporous diaphragm preparation technology, and particularly to a heat treatment device and production line for a microporous diaphragm. It includes a heat treatment unit and a hot air blower. The heat treatment unit includes a first roller group, a second roller group, and a drive motor group. The first roller group includes a plurality of first rollers; the second roller group includes a plurality of second rollers; the first roller group is positioned above the second roller group; each drive motor of the drive motor group is connected to the corresponding first roller shaft in the first roller group; the microporous diaphragm is sequentially and alternately connected to each of the first rollers and each of the second rollers; the heat treatment unit also has an air inlet, which is connected to the hot air blower via a duct. In the device of this application, the microporous diaphragm is distributed in a W-shape, which significantly increases the heating area of ​​the microporous diaphragm. Through the delivery of hot air, a uniform heating effect can be achieved, resulting in high heat treatment efficiency.

[0004] However, existing diaphragm drying equipment typically uses baffles to isolate the inner cavities on both sides of the inlet and outlet. This is to prevent humid air from the inlet from affecting the diaphragm on that side. Furthermore, after prolonged operation, diaphragm drying equipment accumulates dirt that requires cleaning, but the baffles reduce the space within the inner cavity, making it inconvenient for workers to enter the tank for cleaning. Therefore, there is an urgent need to develop a diaphragm drying system to meet the needs of practical applications. Utility Model Content
