Smashing device of waste nickel-hydride power battery

Abstract

The invention discloses a smashing device of a waste nickel-hydride power battery. The smashing device comprises a feeding port, a cutter, a rolling shaft, a discharge port switch, a sieve screen, a control room, an electric motor and a crushed aggregate bin, wherein the waste nickel-hydride power battery of which a shell is disassembled enters the interior of the smashing device through the feeding port, the cutter is arranged in the smashing device, the transmitted waste nickel-hydride power battery is cut and smashed by means of high-speed rotation of the cutter, the cutter is fixed on the rolling shaft, the rolling shaft is connected with the control room and the electric motor, the rotational speed of the rolling shaft is controlled by the control chamber and the electric motor so as to control the cutting speed of the cutter, crushed aggregate smashed by the cutter enters the aggregate bin through a discharge port. By the device, the problem mechanical and rapid smashing of the waste nickel-hydride power battery can be solved, the smashing efficiency is improved, and the working benefit is enhanced.

Description

technical field [0001] The invention relates to the technical field of recycling waste and old new energy nickel-hydrogen power batteries, in particular to a crushing device for waste and old nickel-hydrogen power batteries. Background technique [0002] With the increasing depletion of global oil reserves and the continuous deterioration of the environment, new energy vehicles will become the development direction of future vehicles. Power batteries such as lithium-ion and nickel-metal hydride are characterized by their high specific energy, long life, suitable for high-current discharge, and no pollution. Such excellent comprehensive performance has suddenly emerged, and it has become a green power source of choice for new energy electric vehicles. But at the same time, some problems are also becoming more and more obvious: such as resource bottlenecks of nickel, cobalt, and rare earths, and environmental pollution of scrapped power batteries. [0003] As the main valuabl...

AI Technical Summary

Problems solved by technology

The rare earth resources used in nickel-metal hydride power batteries are mainly mixed rare earth metals such as lanthanum, cerium, praseodymium, and neodymium, which exist in the form of hydrogen storage alloy negative electrode active materials through melting with nickel, cobalt, and manganese. , the chemical composition of the nickel-metal hydride power battery is very complex, and it is difficult to recycle and separate it. In view of the complexity of the chemical composition of the nickel-hydrogen power battery, the battery needs to be pre-treated in the process of recycling, that is, the battery block is processed Broken, but the crushing equipment for nickel-metal hydride power batteries in the prior art is still in the state of development, lacking effective solutions and equipment
