Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of lithium battery crushing, and more particularly to a waste lithium battery crushing and disassembling device. BACKGROUND

[0002] The lithium battery contains many harmful substances, so the waste lithium battery cannot be directly discarded and needs to be recycled to avoid polluting the environment. When recycling the lithium battery, the shell of the lithium battery needs to be crushed and peeled off to further recycle the valuable metal materials in the lithium battery.

[0003] The utility model patent CN221772346U discloses a lithium battery disassembling and crushing device, which sprays the cooling liquid and adsorbent in the first temporary tank and the second temporary tank on the surface of the raw material through the nozzles to realize the cooling of the raw material and the adsorption of harmful gas in the crushing process of the raw material, so as to avoid natural or explosion of the lithium battery due to high temperature and avoid the harmful gas from spreading in the air to cause damage to the external environment and surrounding personnel.

[0004] However, the above-mentioned patent document only relates to the cooling liquid and adsorbent spraying to avoid overheating of the lithium battery. In actual application, there is still a lack of a structure for assisting the crushing roller to crush the large or smooth waste lithium battery. When the large or smooth waste lithium battery contacts the crushing roller, the waste lithium battery cannot be crushed by the crushing roller in the first time, which easily causes the waste lithium battery to be difficult to be crushed by the crushing roller.

[0005] Moreover, there is no blocking effect on the waste lithium battery fragments, which causes the fragments to splash when the waste lithium battery is crushed. In addition, part of the waste lithium battery is accumulated together after being successfully crushed by the crushing roller due to liquid adhesion or incomplete separation, which further affects the crushing and separation effect of the waste lithium battery.
