Description
technical field [0001] The invention relates to the technical field of waste battery recycling, in particular to a solid-liquid screening device for wet recovery of lithium carbonate in waste lithium batteries. Background technique [0002] Lithium carbonate is a basic compound of lithium. It has many industrial uses and is widely used in various fields. Battery-grade lithium carbonate is only used to produce positive electrode materials for lithium-ion batteries such as lithium cobalt oxide and lithium iron phosphate. [0003] When using the wet method to recycle lithium carbonate in waste lithium batteries, multiple solid-liquid separations are required. The current solid-liquid separation method is simply to separate through the filter membrane, which has low working efficiency and requires continuous Replacing the filter equipment is cumbersome. Contents of the invention [0004] The present invention aims at the above-mentioned deficiencies existing in the prior art,...
