Abstract

The invention provides a method and device for recovering a waste air circuit breaker. The method includes the steps that firstly, the waste air circuit breaker is crushed by a hammer crusher into fragments with 5-15-mm granularity, then, fine plastic particles and dust generated in the process of processing the waste air circuit breaker are separated and removed by a cyclone separation system and a bag-type dust remover, ferromagnetic matter in the waste air circuit breaker is separated and crushed by a magnetic separator, and eventually copper, aluminum, silver alloy and other metal concentrated bodies and plastic in the waste air circuit breaker are separated and crushed through a vortex selection method. According to the method and device for recovering the waste air circuit breaker, recovery working efficiency of the waste air circuit breaker is improved.

Description

technical field [0001] The invention relates to environmentally friendly recovery of waste air circuit breakers, in particular to a recovery method and recovery device for waste air circuit breakers. Background technique [0002] Air circuit breaker, also known as air switch, can automatically cut off the circuit when there is overload, short circuit, voltage drop or disappearance in the circuit for reliable protection. Compared with the knife switch, it is safer and more convenient, and does not need to change the insurance. It is the recommended circuit switch device. Modern power systems have higher and higher requirements for the quality and quantity of accessories. Air circuit breakers have multiple protection functions (overload, short circuit, undervoltage protection, etc.), adjustable operating value, high breaking capacity, convenient operation, and safety. So it is widely used now. [0003] In the industrial power system, for every 10,000 kilowatts of power equip...
