[0044] 5. The waste liquid recovery device of the electrode foil, the lifting cylinder rises to the top and fully supports the filter membrane. At this time, part of the repair agent sprayed on the filter membrane flows downward along the outer surface of the filter membrane due to the influence of gravity, thereby quickly covering the filter membrane, further improving the repair effect of the filter membrane.
