Background
The industrial preparation method of the metal lithium is mainly a molten salt electrolysis method, a small amount of bath slag is generated in the high-temperature molten salt electrolysis process, the industrial treatment method comprises the steps of fishing out the lithium slag from an electrolytic bath, pouring the lithium slag into white oil for cooling, and then carrying out hydrolysis recovery treatment on the lithium slag cooled to normal temperature. The lithium slag is hydrolyzed to obtain a three-phase mixture consisting of white oil, hydrolysate and insoluble solid residues, wherein the hydrolysate is a precursor for producing lithium salt products and is a target product in the lithium slag hydrolysis process, the white oil can be recycled, and the insoluble solid residues are treated by solid wastes. However, the current industry often adopts a manual separation method for separating the three-phase mixture in the lithium slag hydrolysate, i.e. the white oil on the upper layer is manually fished out from the surface of the hydrolysate, so that the separation efficiency is low, and the solid residue at the bottom is difficult to clean and discharge in time.
