Lithium iron phosphate battery recycling and treatment equipment

Product Introduction

Aste lithium batteries are precious "urban mines", and green regeneration and material repair technologies for waste power batteries are important foundations for ensuring the recycling and reuse of waste power battery materials. The technology of recycling waste lithium iron phosphate batteries as positive materials is currently quite urgent. Because lithium iron phosphate batteries have a better safety factor, they only start burning at 800 degrees Celsius, making them safer to use than ternary lithium batteries. The recycling of lithium iron phosphate batteries for new energy vehicles mainly utilizes mechanical crushing and separation methods in the recycling and treatment equipment of lithium iron phosphate batteries; In addition to the electrolyte, the lithium iron phosphate battery mainly contains the powder on the positive surface of the lithium iron phosphate. The lithium iron phosphate recovery and treatment equipment achieves waste lithium iron phosphate through physical and mechanical crushing, vacuum separation, vibration screening, specific gravity separation, airflow separation and other steps. Separation and recycling of electrical materials, current collector metals, and plastic separators in batteries.

Operational principle

Using physical sorting technology, a supply line is composed of shredding, crushing, screening, air separation, magnetic separation, and specific gravity sorting. The plastic and metal shells, electrolytes, electrolyte salts, and electromechanical materials in waste lithium batteries have high recycling value. The waste lithium batteries were treated through processes such as discharge, disassembly, crushing, and sorting. Through continuous in-depth research, the process flow was integrated and reduced, and the operating methods were optimized.

First, dismantle the entire rental waste lithium battery into individual batteries. The dismantled waste lithium iron phosphate battery needs to be discharged to prevent ignition during operation. The discharged lithium battery is sent to the battery shredder through a closed conveying device for shredding, and then undergoes secondary crushing. The crushed material enters the magnetic separator to separate the iron, and the magnetically separated material is sent to the negative pressure air separator through a closed conveying system, For the materials in the material, they are collected and sorted separately based on their weight. For example, a mixture of copper and aluminum plastic shells is considered a heavy material, while the remaining mixture of positive and negative materials, plastic membranes, and other materials is considered a light material. Copper aluminum mixture can be sorted out from the sorting machine, and copper and aluminum can be sorted out through the airflow density sorting machine. The mixture of stainless steel and plastic shell can be sorted out through the airflow density sorting. The sorted material can enter the cyclone collector through negative pressure, and then the collected positive and negative powder can be collected through the fan collection process to collect the positive and negative powder. The materials collected by the cyclone collector are screened through a closed screen, and positive and negative value materials can be recovered and separated separately.

Equipment advantages

1. The operation process of the waste lithium iron phosphate battery recycling and treatment equipment is simple, the performance is stable, and the process is relatively mature.

2. The recycling and separation effect of waste lithium iron phosphate batteries is good, with a recovery rate of about 99% for valuable materials such as copper, aluminum, and black powder.

3. The waste lithium iron phosphate battery recycling and treatment equipment completely adopts physical treatment methods such as mechanical crushing, physical screening, and airflow sorting to recover and separate valuable materials from positive and negative materials. The entire process does not add any chemical components or use any chemical treatment process, which is completely environmentally friendly. A set of systems can achieve complete operation of separating and recovering positive and negative materials from waste lithium batteries without the need for other equipment cooperation, and the process is complete, Easy.

4. Automated recycling and separation, with the characteristics of rapid separation of valuable materials and strong recycling ability, has a high degree of automation in resource recycling, which improves the efficiency of recycling rare metals such as copper, aluminum, and lithium.

5. The recycling and reuse of important resources of lithium iron phosphate batteries have been achieved, and the healthy development of the lithium iron phosphate battery industry has been constructed.
