After the lithium battery is retired, it is usually used in steps. After gradual utilization, the battery is recycled again. The crushed metal copper, aluminum and lithium batteries are recycled as batteries for production and recycling.

Lithium battery recycling technology includes the following steps:

1. Sorting of lithium battery materials;

2. Crushing treatment of lithium battery after tearing and sweeping;

3. Separating the preliminary screening diaphragm from the lithium battery fragments;

4. The polar lugs transported by magnetic separation are separated from the lithium battery fragments;

5. Separate the pole ear transported by magnetic separation from the lithium battery fragments, and carry out multi-stage crushing, grinding and fine sorting;

6. Subdivide the lithium battery fragments through multi-stage crushing and grinding to select recyclable materials, perform jump screening, and perform jump screening on the ground and screened lithium battery fragments to separate the remaining recyclable materials.

The working principle of lithium battery recycling: After the lithium battery is completed, the lithium battery is crushed into a lithium battery shredder by a paper shredder and a crusher, and then separated by a mystery machine, collecting the separation fan diaphragm, and preliminary filtering of the exhaust gas generated by the separation diaphragm, Then fine filtration and discharge are carried out in the step of introducing fine filter photolysis.

On the other hand, the remaining lithium battery fragments selected by the gas separator are separated from the tabs by magnetic separation transportation, and the remaining lithium battery fragments transported by magnetic separation are processed by the crusher to form lithium battery fragments. Lithium battery fragments are preliminarily separated by the analyzer.

The preliminarily separated lithium battery fragments are separated through a vibrating screen to separate black powder, copper and aluminum. The remaining lithium battery fragments are introduced into the grinding screen through the vibrating screen, and further ground and finely divided into lithium battery powder through the grinding screen. The vibrating screen is used for vibration separation to screen out black powder, copper and aluminum, and the screening of the remaining lithium battery powder is skipped. Separate the remaining copper and aluminum.

The red exhaust gas generated by the analysis system, the swing screen and the rotary vibrating screen during the operation of the above process is filtered separately, and then introduced into the fine filter decomposition process for fine filtration and discharge.

The air flow absorption separator is used to separate the separator from the lithium battery fragments through a blower, which is not only simple to operate, but also fast in segmentation efficiency. Compared with the existing technology, the environmental protection and energy saving effect is better, and the classification and reuse of materials can be realized. Multi-stage grinding materials are used for multi-stage material processing to make material classification cleaner. The waste gas in the material separation treatment should be preliminarily filtered separately, and the detailed filtration should be carried out through the detailed filtration photolysis procedure to improve the adequacy of the filtration. Set up fine filter photolysis program, photolysis after shower dust drying, multi-directional filtration and purification of waste gas, improve the production environment of the recovery process.

With the continuous miniaturization of electronic products such as mobile phones and computers, the consumption of lithium-ion batteries is also increasing. In addition, ordinary lithium batteries can also be used as a choice for automotive power batteries.

At present, China is the world's battery production and consumption of large countries, the annual battery consumption of 8 billion. Waste batteries are usually disposed of together with household waste through landfill, incineration and composting. The recycling effort is huge and urgent.
