Therefore, used batteries need to be recycled. Acid leaching is an essential and important process in the recycling of used batteries. However, the existing acid leaching equipment does not have the effect of recycling the acid leaching liquid. The demand for acid leaching liquid is large, the cost of acid leaching of used batteries is high, and the position of used batteries in the acid leaching equipment is fixed, and the reaction speed of the acid leaching liquid and used batteries is slow.

[0014] 2. Through the design of the filter screen, the rear-end acid leaching liquid is filtered to achieve the recycling of the acid leaching liquid. Under the action of the circulating liquid supply component, the filtered acid leaching liquid is sent into the acid leaching cylinder for reuse, reducing the acid leaching liquid required for acid leaching. The acid leaching basket can rotate in the acid leaching cylinder, which increases the fluidity of the acid leaching liquid, enables the acid leaching liquid and waste batteries to react better, and shortens the reaction time.
