Description

Technical Field

[0001] This utility model relates to the field of decommissioned power battery crushing technology, specifically a safe live crushing device for decommissioned power batteries. Background Technology

[0002] Retired power batteries refer to batteries removed from new energy vehicles due to performance degradation or reaching the end of their service life. Although these batteries are no longer suitable for use in automobiles, they still have a certain amount of remaining capacity and value, and can continue to play a role through cascade utilization or dismantling and recycling. For retired batteries with less than 20% capacity, professional dismantling is required to extract valuable metals for recycling. These metals include lithium, nickel, cobalt, manganese, etc. If not handled properly, the heavy metals and harmful chemicals in the power batteries will pollute the environment.

[0003] Chinese patent CN221580745U discloses a power battery crushing device. By adding an underwater crushing component, it effectively solves the problems of existing power battery crushing devices, which cannot crush batteries while they are charged, require manual sorting and discharge before entering the crushing process, have long discharge time cycles, and greatly reduce production scale and efficiency.

[0004] In the aforementioned patent, after the power battery is broken, the residue comes into contact with water, and some valuable chemical substances in the battery dissolve in the water. This results in a low resource recovery rate after the battery is broken and a high difficulty in processing battery fragments. Therefore, it does not meet the existing needs. In response, a safe live-line breaking device for retired power batteries is proposed. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model, by setting up a crushing chamber and a feeding channel, allows the battery body to be initially crushed by two extrusion plates in the feeding channel before entering the crushing chamber. Inside the crushing chamber, the battery body passes through a grinding cylinder and is crushed by the grinding blades and fixed blades. Small fragments of the battery body pass directly through the grinding cylinder, while large fragments are ground into small fragments by the grinding protrusions and fixed protrusions. Finally, the small fragments of the battery body fall along the guide plate to the bottom of the crushing chamber and are discharged from the outlet by the discharge plate, thus achieving multi-stage crushing and improving the battery crushing effect.

[0016] 2. This utility model uses a conveyor belt above the feeding channel. The battery body enters the feeding channel along the conveyor belt. After the pusher plate pushes the battery body between two extrusion plates, the sealing plate is closed. The sealing plate, two outer frames, feeding channel, pusher plate, and sealing sleeve form a sealed space. A nitrogen pipe first injects high-concentration pure nitrogen into the sealed space. The two extrusion plates then move towards the middle to initially crush the battery body, thereby destroying its structural integrity to facilitate subsequent crushing operations. A needle is inserted into the battery body to discharge it. Finally, the exhaust pipe absorbs toxic and harmful gases, the sealing plate opens, and the pusher plate pushes the initially crushed battery body into the transfer chamber. Compared with the traditional method of directly crushing the battery body in a high-concentration nitrogen environment, this method reduces the amount of nitrogen required and improves the collection rate of toxic and harmful gases.
