Description

Technical Field

[0001] This utility model relates to the field of electrolyte recycling technology, specifically to a dust removal filter for a waste lithium battery electrolyte recycling system. Background Technology

[0002] Waste lithium-ion batteries mainly consist of a battery casing, positive electrode, negative electrode, electrolyte, and separator. The electrolyte in lithium-ion batteries is the carrier of ion transport in the battery, playing a role in transporting ions between the positive and negative electrodes. It is generally composed of lithium salts, solvents, and additives. If it flows into soil or water sources, it can easily cause serious pollution. For the treatment of electrolyte, solvent combined with pyrolysis is generally used to recycle the electrolyte. However, dust particles are generated during the pyrolysis process. As the electrolyte moves with the air, a dust removal structure is needed to treat the pyrolyzed electrolyte and remove the dust particles.

[0003] In the process of realizing this utility model, the inventors discovered that:

[0004] Existing dust filters in waste lithium battery electrolyte recycling systems generally use simple filtration structures, which are less effective than a combination of filtration and adsorption. Furthermore, the internal filtration structure of these filters is not easy to replace or clean. Summary of the Invention

[0005] In order to solve the problems existing in the prior art, this utility model provides a dust removal filter for a waste lithium battery electrolyte recycling system.

[0012] Beneficial effects: Compared with the prior art, this utility model, through the coordinated arrangement of the installation connector, filter cylinder, rotating baffle, limiting block, and bottom connecting pipe, facilitates easy installation, replacement, and cleaning of the filter cylinder structure. During use, the rotating baffle is opened, the limiting block is removed, and then the filter cylinder is rotated to detach from the threaded bottom connecting pipe. The installation connector is then rotated to remove it. Through the coordinated arrangement of the delivery pipe, adsorption tank, cover, and adsorption column, the electrolyte, after preliminary filtration, is delivered into the adsorption tank through the delivery pipe. After the cover is closed, the bottom of the cover and the inside of the adsorption tank... The side-mounted power interface allows the adsorption column to be energized to adsorb dust particles and contaminants in the electrolyte, thus further adsorbing and removing dust. The observation window and scale bar facilitate the observation of the liquid level inside the device. The combination of the electrically controlled valve, filter tank, and outlet pipe allows the adsorbed electrolyte to be released through the filter tank and outlet pipe during use, further filtering the electrolyte and preventing adsorbed dust particles from being discharged.
