Dry-type separation device and method for waste lead-acid storage battery broken materials

Abstract

The invention discloses a dry-type separation device and method for waste lead-acid storage battery broken objects, and relates to the technical field of waste lead-acid storage battery recycling. The dry-type separation device comprises a centrifugal fan, a plastic bin and a lead granule bin; a separation pipeline with the lower end penetrating into the lead granule bin is fixedly connected to the lead granule bin; the output end of the centrifugal fan is fixedly connected with an air conveying pipeline, the side, away from the centrifugal fan, of the air conveying pipeline penetrates into the separation pipeline, the plastic bin is fixedly connected with a plastic-gas separation pipeline with the lower end penetrating into the plastic bin, and the side, away from the lead granule bin, of the separation pipeline penetrates into the plastic-gas separation pipeline. According to the dry-type separation device and method for the waste lead-acid storage battery broken materials, the separation function is achieved, separated plastic particles are recycled in the plastic-gas separation device, and meanwhile air is purified and recycled, so that energy consumption is reduced, high-speed and high-pressure exhaust gas is not generated, mechanical energy consumed by air suction is reduced, and workshop environment pollution is completely eradicated.

Description

technical field [0001] The invention relates to the technical field of recycling waste lead-acid batteries, in particular to a dry-type separation device and method for broken pieces of waste lead-acid batteries. Background technique [0002] In the dry-type lead and plastic separation process of lead resource recovery from waste lead-acid batteries, mechanical cutter splitting is mainly used, and the output of demolition and crushed materials is high. The processing system is open to the workshop environment, and there is residual acid mixed, which pollutes the production environment Serious; there are many moving mechanisms and parts, lead mud adhesion is difficult to clean, the failure rate is high, and maintenance is difficult; occupational hygiene conditions are poor; production efficiency is difficult to improve. [0003] In the prior art, for the recovery of lead-acid batteries, the crushing and separation system is generally used. Using the crushing-hydraulic separat...
