[0034] Working principle: During use, the power is turned on, and the battery electrolyte is fed into the feed tank 2 through the feed inlet 3. Then, the additive is fed into the feed tank 2 through the additive tube 5. At this time, the first rotary motor 23 starts and drives the gear 1 25 to rotate. The rotation of gear 1 25 drives gear 2 26 and gear 3 27 to rotate, causing the first rotating rod 20 and the second rotating rod 22 to rotate clockwise and counterclockwise. The stirring rod 21 installed on the rotating rods stirs the liquid, making the liquid more uniform. At this time, the toxic gas generated after the electrolyte and additive are stirred is discharged through the exhaust pipe 4. After the liquid is processed, it is discharged through the solution outlet 18 and falls onto the filter cartridge 14. The impurities remaining in the liquid fall onto the filter cartridge 14. At this time, the second rotary motor 12 starts, driving the screw rod 13 and the screw blade 8 to rotate and transport and remove the impurities on the filter cartridge 14. The filtered liquid enters the solution collection cart 9 through the filter outlet 17 at the bottom for collection. At this time, the impurities that cannot be cleaned on the filter cartridge 14 still remain. The cleaning nozzle 29 is activated by the moving component 16 driving the cleaning ring 15 to move horizontally on the filter cartridge 14 to clean the filter cartridge 14 and enhance the filtration effect.
