Environment-friendly waste circuit board crushing, sorting and recycling equipment

Abstract

The invention discloses environment-friendly waste circuit board crushing, sorting and recycling equipment. The environment-friendly waste circuit board crushing, sorting and recycling equipment comprises a crushing machine box, wherein the crushing machine box is internally provided with a crushing roller, and a supporting frame is fixedly connected to the top of the crushing machine box; a feeding hopper is fixedly connected to the top of the supporting frame, a discharging pipe is arranged under the feeding hopper, a sliding rail is arranged inside the discharging pipe, a moving sliding block is slidably connected to the outer side of the sliding rail, and a supporting connecting rod is rotatably connected to the bottom of the moving sliding block; and a switch valve is rotatably connected to the bottom of the supporting connecting rod, and the discharging pipe is rotatably connected to the bottom of the switch valve. The invention relates to the technical field of environmental protection recycling. The environment-friendly waste circuit board crushing, sorting and recycling equipment achieves the purpose of crushing and separating waste circuit boards, and the waste circuit boards are rapidly crushed and separated by adopting different characteristics of materials, integrated operation equipment is adopted to improve the work efficiency, the work time is reduced, the structure is simple, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of environmental protection recycling, in particular to an environment-friendly crushing, sorting and recycling equipment for waste circuit boards. Background technique [0002] With the acceleration of the updating speed of electronic products, the amount of discarded printed circuit boards (PCBs), which are the main components of electronic waste, is also increasing. The environmental pollution caused by waste PCBs has also attracted the attention of various countries. Waste PCBs contain heavy metals such as lead, mercury, and hexavalent chromium, as well as toxic chemicals such as polybrominated biphenyls (PBB) and polybrominated diphenyl ethers (PBDE), which are used as flame retardant components. Groundwater and soil have caused huge pollution, which has brought great harm to people's life and physical and mental health. On the waste PCB, there are nearly 20 kinds of non-ferrous metals and rare metals...
