Description

UNDERWATER CRUSHING MECHANISM FOR ALUMINUM HOUSING BATTERY

TECHNICAL FIELD

The present invention relates to the technical field of waste battery crushing, and more particularly, to an underwater crushing mechanism for an aluminum housing battery.

BACKGROUND

Waste batteries need to be discharged, crushed, screened, etc. in sequence when being recycled. Most of the common waste battery crushing mechanisms are dry crushing to mechanisms, that is, batteries are crushed by a crushing auger or a crushing roller, battery housings are peeled off, and the battery housings are separated from inner cores. Although the dry crushing mechanisms can fully peel off battery housings, such equipment will generate a large amount of debris splashing and electrolyte leakage in the process of crushing a large number of batteries. The splashing debris and volatile electrolytes can easily pollute the environment where the processing equipment is located, affecting the environment safety.

Moreover, some waste batteries will be short-circuited due to incomplete discharge when being crushed. Thus, when a crushing mechanism crushes batteries for a long time, the crushing end will generate a lot of heat energy to make battery debris spark and burn, which will not only damage the crushing end of the crushing mechanism, but also affect the environment safety due to exhaust gas generated by electrolyte combustion. Meanwhile, when existing crushing mechanisms crush batteries for a long time, the accumulation of crushed material easily happen, and the full crushing of batteries cannot be guaranteed, so that it is easy to cause aluminum housings in the waste battery crushed material to be insufficiently separated from other particles, which not only cannot fully recycle aluminum housings and other debris of waste batteries, but also reduces the particle recovery rate of waste batteries, resulting in waste. Therefore, crushing mechanisms adopting a method of underwater crushing can achieve charged crushing and reduce electrolyte combustion on the one hand and can also directly clean up the residual electrolytes on housings and inner cores on the other hand to ensure that the separated aluminum housings and other debris can be easily subjected to subsequent processing, so as to solve the problems mentioned above.
