Description

Technical Field

[0001] This utility model relates to the field of battery separator technology, and in particular to a liquid removal tank used in separator washing production lines. 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] In current diaphragm manufacturing processes, dichloromethane is typically used to clean the diaphragm. According to existing publication CN218251690U, a rigid scraping device suitable for an inlet sealing groove is disclosed, comprising several rigid scraping mechanisms arranged along the diaphragm conveying path. Each rigid scraping mechanism includes a first scraping module and a second scraping module. The first scraping module abuts against one end face of the diaphragm, and the second scraping module abuts against the other end face of the diaphragm. In this invention, the first and second scraping modules scrape away the mixed liquid from the diaphragm surface, preventing the mixed liquid from entering the next process and causing material contamination.

[0004] However, even though the scraping device in the aforementioned descaling tank removes residual dichloromethane from the diaphragm using a rigid scraping mechanism, a small amount of dichloromethane still adheres to the diaphragm. Therefore, there is an urgent need to develop a descaling tank for use in diaphragm washing production lines to meet practical application requirements. Utility Model Content

[0005] The purpose of this invention is to provide a liquid removal tank for use in diaphragm washing production lines to solve the above-mentioned defects.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A dehydration tank for use in a diaphragm washing production line includes a tank body. The interior of the tank body is a cavity for conducting diaphragm material. A discharge port and a feed port are respectively opened on both ends of the tank body. Several rotatable transmission rollers are provided inside the cavity. Rotatable feed port rollers are provided on both sides of the tank body near the discharge port and the feed port. A rotatable dehydration roller is provided on the feed port roller on the discharge port side. A swinging mechanism is provided between the two ends of the dehydration roller and the tank body.

[0007] As a further embodiment of the above description, the liquid removal roller consists of an inner shaft and an outer shaft. The outer shaft is a hollow cylindrical structure and is rotatably fitted onto the surface of the inner shaft. The two ends of the inner shaft are connected to the swing mechanism.

[0008] As a further embodiment of the above description, the swing mechanism includes a bushing, a rotating plate, a swing arm, and a cylinder. One end of the rotating plate and the swing arm are respectively fixedly connected to both ends of the bushing. The end of the inner shaft is connected to the end of the rotating plate away from the bushing. The output shaft of the cylinder is connected to the end of the swing arm away from the bushing.

[0009] As a further embodiment of the above description, the surface of the bushing is fitted with a mounting bearing, and the bushing is rotatably mounted on both sides of the groove via the mounting bearing.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: a rotatable dehydration roller is provided on the discharge port roller on one side of the discharge port. The dehydration roller and the discharge port roller are brought into contact by a swing mechanism, so that the dichloromethane on the diaphragm surface can be squeezed downward by the dehydration roller and the discharge port roller. This allows the fine dichloromethane that cannot be completely scraped off by the scraper to be squeezed and dripped downward by the dehydration roller and the discharge port roller, thereby improving the dehydration effect of the dehydration tank on the diaphragm.
