Embodiment Construction
[0036] Referring to the accompanying drawings, the method for physical screening and classification of hybrid electronic components of the present invention is: putting the mixed electronic component aggregates containing resistors, capacitors, small transformers, inductors, connector wires, etc. into the uppermost vibrating screen of the multi-layer vibrating screening machine On the net, the multi-layer vibrating screening machine is equipped with supporting springs on the frame, and the upper end of the supporting springs is connected to support the multi-layer vibrating screen. The vibrating screen is installed obliquely, and the inclination adjustment device of the vibrating screen is added on one side of the frame. The aggregate of mixed electronic components first vibrates in the horizontal and vertical axes on the uppermost vibrating screen. The mesh structure design of the vibrating screen is different, so a single type of electronic components is left on the top vibra...

The invention relates to method and equipment for physically screening and classifying mixed electron components. In the invention, mixed electron components are put on an uppermost vibrating screen of a multi-layer vibrating and screening machine, and multiple layers of vibrating screens are supported by a supporting spring on a stand; the bottom of a lowermost vibrating screen is provided with a transverse axial vibration motor and a vertical axial vibration motor; the multiple layers of vibrating screens are obliquely arranged, and a vibrating screen inclination regulating device is additionally arranged on the stand; the designs of mesh structures of various layers of vibrating screens are different; and the electron components fall on lower vibrating screens from the meshes of upper vibrating screens and are screened and classified by all the layers of vibrating screens. The method has the advantages of mechanical operation, high efficiency, low noise, no dust, no waste gas and no environmental pollution, greatly lightens the labor intensity of workers; and particularly, the mesh structures of various screens have artful designs, creativity and good classification effect.
Description
Technical field: [0001] The invention relates to the technical field of environmental protection, in particular to a physical screening and classification method and equipment for waste mixed electronic components. Background technique: [0002] With the continuous progress of modern human industrial civilization, the replacement frequency of various electronic products is constantly accelerating. Thereupon, electronic waste products are also produced in large quantities. The main component of electronic waste products is printed circuit board (referred to as PCBA). PCBA is composed of two parts: PCB substrate and electronic components assembled on its surface. The two parts are composed of copper, aluminum, nickel and precious metal enrichment. At the same time, in a short period of time in recent years, a huge army of PCBA dismantling has emerged to dismantle and classify waste PCBAs, extract metals, and recycle them. At present, the main schemes for screening and classi...
