Solution recovery pretreatment device for lead-acid storage battery

Abstract

The invention discloses a solution recovery pretreatment device for a lead-acid storage battery. The solution recovery pretreatment device comprises a main box body, wherein the main box body is internally provided with a lead-acid solution through cavity with an upward opening, the lower side of the lead-acid solution through cavity is provided with a stirring cavity in a communicated mode, the left side of the stirring cavity is provided with a floating block cavity in a communicated mode, the floating block cavity is connected with a floating block in a sliding fit mode, the lower end wallof the stirring cavity is fixedly connected with an acid-base sensor corresponding to the lead-acid solution through cavity, the upper side of the stirring cavity is provided with an alkali liquor feeding mechanism, the lower side of the stirring cavity is provided with a treatment liquid through cavity in a communicated mode, and a pH value in the stirring cavity is sensed through the acid-base sensor, so that the feeding of alkali liquor is controlled, and the alkali liquor is prevented from being excessive or insufficient; during neutralization reaction, a stirring rod keeps rotating, so that the neutralization is sufficient; and after the treatment liquid enters an extrusion cavity, filtering is completed under the extrusion of a piston push plate, so that lead paste remains on the surface of a filter screen, the lead paste is lifted through a lifting box, and a scraping plate stretches out to complete automatic scraping of the lead paste, so that the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of waste batteries, in particular to a solution recovery pretreatment device in a lead-acid storage battery. Background technique [0002] As a common means of transportation in people's daily life, electric vehicles are usually powered by lead-acid batteries. The lead-acid solution in the lead-acid battery contains a large amount of recyclable lead, which is of great value. The current recovery of lead-acid solutions usually uses alkali The method of filtering the lead paste after neutralizing the alkaline solution and then recovering it, but improper control of the lye content will lead to insufficient neutralization or alkaline treatment solution, which will lead to environmental pollution. Manual scraping is required, and the efficiency is low. Contents of the invention [0003] Aiming at the deficiencies of the above-mentioned technologies, the present invention proposes a solution recovery pretreatm...
