Metal air battery solid-liquid separation device

The invention provides a metal air battery solid-liquid separation device, which comprises a tank body, a pushing part and a filtering part, wherein the tank body is provided with a cavity, the pushing part is operated to slide in the cavity, a filter residue outlet, a filtrate outlet and a liquid inlet are formed in the tank body, the filtering part is rotatably connected to the tank body, a mixed liquid flows into the cavity through the liquid inlet, the filtering part is operated to rotate in the cavity relative to the tank body, and performs solid-liquid separation on the mixed liquid entering the cavity to obtain filtrate and filter residue, the filtrate is discharged through the filtrate outlet, and the filter residue is discharged through the filter residue outlet. According to theinvention, with the metal air battery solid-liquid separation device, the filter residue adsorbed on the surface of the filtering part can generate centrifugal force so as to be separated from the filtering part, so that the
