Description

Technical Field

[0001] This utility model relates to the field of fluid sensor technology, and in particular to a diaphragm drying tank. 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 tanks use several drive rollers to distribute and transport microporous diaphragms in a W-shape, significantly increasing the heating area of ​​the diaphragms. While this achieves uniform heating and high heat treatment efficiency through hot air delivery, the low density of the hot air causes it to tend to accumulate at the top of the drying tank. Even with increased contact surface area, different temperature zones still exist within the tank, resulting in inconsistent drying effects at different locations. Therefore, there is an urgent need to develop a diaphragm drying tank to meet practical application requirements. Utility Model Content
