Abstract

The invention discloses a recycling system for waste electrical and electronic products. The recycling system is characterized by comprising a control system as well as a crushing system, a separation system, a dust collection system, a waste gas collection system and a draught fan which are controlled by the control system, wherein the crushing system comprises a knocking crusher, the separation system comprises a winnower and a plastic and metal separation device, and the knocking crusher, the winnower and the plastic and metal separation device are connected through conveyer devices sequentially to form a plastic and metal separation production line; the knocking crusher and an air outlet of the winnower are connected with the dust collection system respectively for collecting light materials and dust of the whole recycling system; an air outlet of the dust collecting system is connected with the waste gas collection system; and the draught fan is connected with the waste gas collection system, so that the knocking crusher, the winnower, the dust collection system and the waste gas collection system are in negative pressure states. The system can be applied to crushing and separation treatment of various waste electrical appliances such as a refrigerator, a circuit board and the like respectively.

Description

technical field [0001] The invention relates to a recycling and processing system for waste electrical and electronic products. Background technique [0002] A large number of waste electrical and electronic products are produced in our country every year. As people's awareness of environmental protection continues to increase, the recycling of waste electrical and electronic products has attracted increasing attention from the society. At the same time, with the implementation of the "Household Appliances Trade-in for New" policy and the promulgation of the "Regulations on the Administration of Recycling and Disposal of Waste Electrical and Electronic Products" and the "Administrative Measures for the Collection and Use of Disposal Funds for Waste Electrical and Electronic Products", enterprises for the recycling and disposal of waste electrical and electronic products have been established one after another across the country. At present, the "Guidelines for the Qualificat...
