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

Embodiment Construction
[0023] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.
[0024] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or a central element may also exist. When an element is considered to be "connected" to another element, it can be directly connected to the other element or an intermediate element may be present at the same time.
[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meani...

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 e-waste is also increasing. According to statistics, e-waste is increasing at an annual rate of 16-28%, 3-4 times faster than the growth rate of total waste, and e-waste generates 500 million tons of hazardous and toxic waste each year, which is one of the largest sources of human pollution. One. Scrap circuit boards are the most common electronic waste, appearing in almost all electronic and electrical products, and the number is huge. The circuit board is a mixture of glass fiber reinforced resin and various metals. The metal content in the circuit board is as high as 40%, ...
