Method and device for extracting metal lead powder through non-equipotential solid-phase electrolysis of waste lead battery paste

The invention discloses a method and device for extracting metal lead powder through non-equipotential solid-phase electrolysis of waste lead battery paste. The extraction method comprises the following six steps: setting of the effective discharge area of anode frames, eccentric distance adjustment, charging, electrolysis, lead extraction and electrolyte recycling. The device comprises cathode frames, the anode frames and an electrolytic bath, the anode frames and the cathode frames are fixedly arranged in a staggered mode at intervals through insulating plates, and during electrolysis, the cathode frames and the anode frames are integrally hoisted and placed into the electrolytic bath for electrolysis. The effective discharge area of an anode can be increased to be several times of that of a cathode, the utilization efficiency of the anode is high, non-equipotential electrolysis can generate an eccentric magnetic field to enhance automatic circulation of electrolyte, eliminate the layering phenomenon of the
