Waste circuit board resource recycle and treatment system

Abstract

The invention relates to a waste circuit board resource recycle and treatment system. The waste circuit board resource recycle and treatment system comprises crushing mechanisms, a first centrifugal fan, a first cyclone separator, an air flow sorting machine, a screening mechanism, a second centrifugal fan, a second cyclone separator and an adjustment and control valve; according to the waste circuit board resource recycle and treatment system, the multiple stages of crushing mechanisms are arranged, so that waste circuit boards can be fully crushed; the first centrifugal fan, the first cyclone separator, the air flow sorting machine, the screening mechanism, the second centrifugal fan, the second cyclone separator and the adjustment and control valve form a multi-stage sorting mechanism cooperatively, so that crushed materials output by the crushing mechanisms are fully sorted; the separation efficiency for the crushed materials is improved; manual crushing and sorting are not needed in the whole process; and the sorting efficiency is high.

Description

technical field [0001] The invention relates to the field of waste circuit board resource recovery, in particular to a waste circuit board resource recovery processing system. Background technique [0002] With the rapid development of electronic technology and information technology, electronic and electrical products have been widely used in people's production and life. At the same time, the amount of electronic waste is also increasing. According to statistics, electronic waste is increasing at an annual rate of 16-28%, which is 3-4 times faster than the growth rate of total waste, and electronic waste will produce 500 million tons of hazardous and toxic waste every year, which is one of the largest sources of pollution for human beings. one. Waste circuit boards are the most common electronic waste, appearing in almost all electronic and electrical products, and the quantity is huge. Circuit boards are a mixture of glass fiber reinforced resin and various metals. Th...

Problems solved by technology

[0003] At present, for the early stage crushing and recycling industry of waste circuit boards, the waste metal mixture and metal mixture of waste circuit boards are separated manually, which is low in efficiency and high in labor costs. A few powerful recycling companies use coarse crushing equipment to crush waste circuit boards. In the later stage, an electrostatic separator is used to separate the non-metallic mixture and the metal mixture. This method not only produces dust pollution and air pollution in the production process, but also the separation effect is not ideal. In the subsequent process, due to the poor separation effect, it increases Post-recycling equipment stress and reduced metal recovery rates
