Time：2022-10-09 18:04:20

The soft pack battery is the third generation power battery developed on the basis of the original steel shell, aluminum shell and plastic shell battery. The soft-pack lithium battery is packaged with aluminum-plastic film on the shell structure. With the extensive use of the soft-pack battery, after its failure and scrapping, the soft-pack battery is rich in nickel, cobalt, manganese, lithium, copper, aluminum and other elements. , it is necessary to carry out resource recycling. The existing pretreatment process includes multiple steps such as discharge, dismantling, multi-stage crushing and physical sorting.

The waste power battery recycling, dismantling and separating equipment can solve the problem of recycling and processing waste soft pack power batteries, reduce the harm of waste soft pack power batteries to the ecological environment, and improve the utilization rate of resource recovery. A dismantling and crushing device for waste soft-pack power batteries, characterized in that:

The device includes a dismantling device and a crushing device, the dismantling device is located at the front end of the entire device, and the relative positions of the components included in the dismantling device are higher than those included in the crushing device, wherein : The dismantling equipment further includes a conveying platform, a lye spray device, a grabber, a shell crusher and a waste liquid outlet.

Wherein: the waste soft-pack power battery to be processed is transported to the dismantling equipment through the conveying platform, and the upper cover of the shell of the waste soft-pack power battery is cut by the cutting machine in the dismantling equipment; the The lye spray device is used to release lye to neutralize the electrolyte during the dismantling process of the dismantling equipment; the grabber is used to directly remove the battery pack from the square aluminum casing after cutting the battery casing. Take out.

The casing crusher is used for crushing the battery plastic casing after the grabbing machine takes out the battery pack;

The waste liquid outlet is used to collect the waste liquid after neutralizing the electrolyte;

The crushing equipment further includes a battery pack lower outlet, a battery pack upper outlet, a crushing bin, a temporary bin for scraps and a scrap storage bin, wherein: the battery packs taken out by the grab machine enter the lower outlet of the battery pack after passing through the conveyor belt , and then pass from the lower outlet of the battery pack to the upper outlet of the battery pack after passing through the first-level conveyor belt,

The battery pack is crushed by a shredder that enters the crushing equipment from the upper outlet of the battery pack; the battery scraps after crushing are stored in the crushing bin, and then the scraps in the crushing bin are removed by a conveyor belt. Transport to the temporary warehouse for scraps.

The scraps in the temporary scrap bin are then transferred to the scrap storage bin through a secondary conveyor belt.

The device described in the embodiment of the invention has the following advantages:

1) Solve technical problems such as dismantling and crushing of waste lithium-ion soft pack power batteries;

2) Solve technical problems such as leakage, volatilization, decomposition and pollution of electrolyte during dismantling;

3) Solved the dismantling and peeling of the hard plastic shell of the battery;

4) The double-shaft reverse-rotating shredder is adopted to solve the crushing problem of the soft aluminum-plastic shell;

5) The automation control of the device is more comprehensive, and the entire production operation requires only 3 to 5 people, which greatly reduces the labor intensity of workers, improves the efficiency of dismantling and crushing, and improves the recycling efficiency of materials;

6) The device is controlled by electrical control and monitoring system, with a high degree of overall automation, good battery crushing effect, zero discharge of waste liquid in the production cycle, and achieves the technical indicators of clean production.
