Method and equipment of aluminum capacitor disassembly and resource recovery

Abstract

The invention relates to a method and equipment of aluminum capacitor disassembly and resource recovery. An aluminum capacitor is delivered to a hammer-type crushing cavity by a feed hopper and a feed regulating valve; the hammer-type crushing cavity is formed by a gear ring plate, a hammer-type prop and space thereof; the hammer-type prop is driven by a crusher electric motor to rotate; the hammer-type prop is provided with a plurality of movable hammers; the hammer-type crushing cavity is provided with a screen at the lower part; the movable hammers interact with the gear ring plate to crush and separate the aluminum capacitor into crushed aluminum blocks and crushed electrolytic paper which are collected by an aggregate bin after being screened by the screen; a cyclone separator generates negative pressure to suck the crushed aggregate into the cyclone separator though a connection duct; the crushed aluminum blocks are separated from the crushed electrolytic paper; the crushed aluminum blocks are collected in the aluminum block aggregate bin; the crushed electrolytic paper is conveyed to a centrifugal fan through the connection duct at the upper end of the cyclone separator; and finally, the centrifugal fan outputs the crushed electrolytic paper to an electrolytic paper recovery device with a wire mesh. By adopting a physical method for crushing, the invention has no secondary pollution and is beneficial for resource recovery, environmental protection and energy saving.

Description

Technical field: [0001] The invention relates to the technical field of environmental protection, in particular to a method and equipment for dismantling aluminum capacitors and recycling resources. Background technique: [0002] After my country entered the peak period of electrical waste, the recycling and disposal of waste electronic products was quickly put on the agenda. It is reported that after my country enters the peak period of electrical waste, it is estimated that 5 million TV sets, 4 million refrigerators, and 6 million washing machines will be scrapped every year. In the next 5 to 10 years, the amount of scrapped computers will also reach more than 5 million sets per year. At the same time, the industry of e-waste recycling and reuse has mushroomed. Used e-waste is mainly composed of plastics, printed circuit boards (PCBs), glass and metal brackets. The printed circuit board (PCB) occupies the main body of electronic waste, mainly composed of resistors, capac...

AI Technical Summary

Problems solved by technology

[0006] The above treatment method 1 solves the problem of utilizing the metal inside the capacitor components, but incineration will produce a large amount of toxic gas, which will cause secondary pollution to the environment

Treatment method 2 uses direct landfill for capacitor components, which not only causes waste of resources but also pollutes the landfill soil. In short, the above-mentioned landfill and incineration methods not only pollute the environment, but also waste resources
