Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery separator processing, and particularly relates to a water absorption device for a lithium battery separator extraction tank which is convenient for quickly replacing a water pipe. Background Technique

[0002] A lithium battery separator extraction tank is a device used for separating mixtures, mainly applied in the production process of lithium battery separators. The extraction tank realizes the effective separation of target substances and impurities by utilizing the solubility differences of different substances in different solvents. In the recycling of lithium batteries and the production of separators, the extraction tank plays a key role. Extraction is an important link in the production process of wet lithium battery separators. The commonly used extractant is dichloromethane. However, due to trace amounts of water in dichloromethane or moisture in the environment mixing into the extraction tank, the content of this water will gradually increase and float above the dichloromethane, resulting in water marks on the surface of the separator, which affects the apparent performance of the separator. In order to improve the processing efficiency of lithium battery separators, a water absorption device is required. However, the existing water absorption devices still have the following deficiencies:

[0003] For example, the utility model with the application number 201921241127.7 discloses a water absorption device for a wet lithium battery separator extraction tank and a lithium battery separator extraction tank. The other end of the support of this utility model is movably installed on the side wall of the wet lithium battery separator extraction tank to adjust the water absorption component to be on the surface of the extraction liquid and absorb the water in the extraction liquid, which can effectively prevent water marks from forming on the surface of the separator and improve the apparent performance of the separator. However, for comparative documents similar to the above application, when the existing water absorption device is in use, since most of the water pipes of the water absorption device are fixedly installed inside the extraction tank through fastening bolts, it is time-consuming and laborious to replace the water pipes and increases the labor intensity of workers, resulting in the problems of reduced practicability and use efficiency of the water absorption device.
