Automatic Efficient Separation And Recovery Of Waste Lithium Battery Equipment Production Plant

Introduction

The waste lithium battery contains various rare raw materials such as copper, aluminum, graphite powder and lithium powder, and has high recycling value. Lithium battery mainly consists of shell, positive electrode, negative electrode, electrolyte anddiaphragm. The positive electrode is formed by coating lithium cobaltate powder on two sides ofan aluminum foil current collector through PVDF which plays a bonding role;The negative electrode structure is similar to the positive electrode and consists of carbon powder bonded toboth sides of the copper foil current collector. At present, the research on the recycling of wastelithium batteries is mainly focused on the recovery of high-value anode precious metals cobaltand lithium. Copper in the negative electrode of waste lithium battery (content up to 35%) is animportant production raw material widely used.Carbon powder adhered to it can be used asadditives such as plastics and rubber. Based on the structural characteristics of lithium batteries,our company adopts an environmentally-friendly physical separation process to realize efficientseparation and recovery of waste lithium batteries.

Products Description

The pretreatment process of waste lithium ion batteries mainly comprises the following steps:afterdischarging the recovered waste batteries, crushing, magnetic separation, air separation,crushing, gravity separation, screening and other processes are carried out by mechanical equipment,so that the powder on the positive and negative pole pieces is effectively separated from thecopper aluminum foil, and the batteries are treated as valuable materials.

Technological Process

The entire production line of lithium battery recovery equipment is fed by conveyor materials into the crusher of the first process for coarse crushing. The coarse crushed materials are fed by conveyor to the secondary crusher for secondary crushing. The crushed materials from the secondary crusher enter the conveyor and magnetic separation equipment is installed to separate the iron in the materials. After the iron is removed by the material conveyor and magnetic separator, it enters the three crusher for fine crushing, crushing the material to powder. Materials in powder state enter the cyclone separator through the negative pressure system for air filtration, and then fall onto the air flow separator through the fan. The air flow separator separates materials of different densities to obtain metal separation, while all non-metals are brought into the pulse dust collector through the negative pressure system for concentration. The filtered tail gas will continue to be sent by the negative pressure system to the tail gas treatment equipment for air purification, so that it meets the national emission standards before being discharged at high altitude.

Shredder: Shredded lithium batteries into smaller pieces.

Hammer crusher: For the secondary crushing of shredded materials.

Grinder: For the grinding of the crushed materials.

Separation machine: Separate the materials after being ground.

Collector: Collect and release the dust .

Pulse purifier (air cleaner): Clean all the dust produced during the operation of the wholesystem.

Classifying screen:Screen the materials sorted by the separation machine,and screen out oflarger metal materials.

Magnetic machine: Separate nickel from the metals.

Gravity separator:Separate those finer materials got from the screening machine and separatethe metal completely.

High-pressure blower: Keep the whole system in a negative state so as to collect the materialsand purity the air.
