AI Technical Summary

Technical Problem

The existing waste battery refining raw material equipment cannot be completely crushed when dealing with waste batteries with hard texture or special structure, resulting in some raw materials remaining, affecting the refining efficiency and recovery rate.

Method used

A multi-stage crushing mechanism including a rotary cutting assembly and an extrusion crushing assembly is designed to cut the used battery into smaller blocks through the rotary cutting assembly, and then the particles are further refined through the synergy between the extrusion crushing assembly and the ultrasonic vibration assembly.

Benefits of technology

Through the synergistic action of the multi-stage crushing mechanism, the particle size of the battery material is significantly improved, which accelerates the dissolution speed and greatly improves the raw material refining efficiency and recovery rate.

Abstract

The invention discloses a waste battery raw material refining device which comprises a box body, a filter plate is arranged in the box body, a multi-stage crushing mechanism is arranged above the filter plate, and the multi-stage crushing mechanism comprises a rotary cutting assembly and an extrusion crushing assembly; the rotary cutting assembly comprises a cutting motor, the cutting motor is installed on the outer side wall of the box body, the output end of the cutting motor is connected with a rotating shaft, and a plurality of cutting blade sets are arranged on the rotating shaft. The extrusion crushing assembly comprises a driving extrusion plate and a driven extrusion plate which are oppositely arranged, the driving extrusion plate is connected to the side wall of the box body through a telescopic air cylinder, the driven extrusion plate is connected with the side wall of the box body through a telescopic rod, and in addition, the front end face of the driving extrusion plate and the front end face of the driven extrusion plate are provided with staggered crushing teeth; and ultrasonic vibration assemblies are arranged in the two. Through the synergistic effect of the multiple stages of crushing mechanisms, crushed battery materials are smaller in granularity and more uniform, the dissolving speed is increased, and the raw material refining efficiency is improved.
