There are electrolytes in organisms, electrolytes used in the battery industry, and electrolytes in industries such as electrolytic capacitors and supercapacitors.

[0003] For example, the Chinese authorized patent with announcement number CN219783946U (device for recycling waste electrolyte): includes a recycling barrel, the inner wall of which is installed with a filtering device. The beneficial effects of the utility model are: by installing bevel blocks, bevel grooves, strip plates, strip blocks, filter screens, openings, fixed blocks, and grooves, a better function of filtering solid impurities in the electrolyte is achieved. When the electrolyte is poured into the holding tank of the recycling barrel, the electrolyte will flow down along the bevel of the bevel block, the electrolyte will be separated from the solid impurities through the filter screen, and then flow into the holding tank through the opening. Because the strip plates are fixed at an angle, in the process of pouring the electrolyte into the holding tank, the solid impurities will be carried to the bottom of the strip plates by the water flow and enter the grooves of the fixed blocks, thereby achieving a better function of filtering solid impurities in the electrolyte.

[0004] However, when the existing electrolyte waste liquid is recovered, solid-liquid separation is performed through a filter screen, and the mesh of the filter screen is easily blocked, resulting in low separation efficiency; therefore, it does not meet the existing needs. In this regard, we propose a waste liquid recovery device for electrolyte production. Utility Model Content
