Description
A crushing and recycling device for lithium-ion batteries Technical Field
[0001] This invention relates to the technical field of lithium-ion battery crushing, and in particular to a crushing and recycling device for lithium-ion batteries. Background Technology
[0002] A lithium-ion battery is a rechargeable battery that primarily relies on the movement of lithium ions between the positive and negative electrodes to function. During charging and discharging, Li+ ions repeatedly insert and extract between the two electrodes: during charging, Li+ ions extract from the positive electrode, pass through the electrolyte, and insert into the negative electrode, leaving the negative electrode in a lithium-rich state; the reverse occurs during discharging.
[0003] While existing recycling equipment can recycle and crush lithium-ion batteries, it still has many shortcomings: 1. Chinese patent CN210787680U discloses a crushing device for lithium-ion battery recycling, specifically disclosing that: the lithium-ion battery to be processed is put into the crushing chamber through the feed inlet; the second motor is started to drive the active shaft roller to rotate; and the rotation of the active and driven shaft rollers squeezes the lithium-ion battery. After being squeezed, the lithium-ion battery moves downward, so that the lithium-ion battery is located at the top of the active and driven crushing blades. The first motor is started to drive the active crushing blade to rotate, thereby crushing the lithium-ion battery. This patent has a relatively simple structure and cannot effectively crush lithium-ion batteries. At the same time, the liquid inside the battery is prone to leakage, polluting the environment. In addition, although the existing extrusion and crushing devices use extrusion and crushing components, the existing extrusion chamber and crushing chamber cannot effectively crush and crush the battery pack.

[0039] The first vertical crushing blade 30, the second vertical crushing blade, the third vertical crushing blade, the fourth vertical crushing blade, the fifth vertical crushing blade, and the sixth vertical crushing blade are all equipped with transverse vertical blades 31, which can fully crush the material. The lengths of the first vertical crushing blade 30, the second vertical crushing blade, the third vertical crushing blade, the fourth vertical crushing blade, the fifth vertical crushing blade, and the sixth vertical crushing blade increase sequentially. A crushing triangular groove 32 is provided below the crushing cylinder 6.
[0040] A detachable crushing blade 33 is provided below the first fixing rod 22, the second fixing rod 23, and the third fixing rod 24.
