Embodiment Construction

[0036] Referring to the accompanying drawings, the physical screening and classification method of the hybrid electronic components of the present invention is as follows: the aggregates of the hybrid electronic components containing resistors, capacitors, small transformers, inductors, connector wires, etc. are put into the uppermost vibrating screen of the multi-layer vibrating screening machine. On the net, the multi-layer vibrating screening machine is equipped with a support spring on the frame, the upper end of the support spring is connected to support the multi-layer vibrating screen, and the bottom of the bottom layer of the vibrating screen is equipped with a horizontal axial vibration motor and a vertical axial vibration motor. The vibrating screen is installed obliquely, and a vibrating screen inclination adjustment device is added on one side of the frame. The aggregates of mixed electronic components first vibrate horizontally and vertically on the uppermost vibrat...

Abstract

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 method and equipment for physical screening and classification of waste mixed electronic components. Background technique: [0002] With the continuous progress of modern human industrial civilization, the frequency of replacement of various electronic products is accelerating. As a result, electronic waste products are also produced in large quantities. The main components in electronic waste products are printed circuit boards (PCBA for short). PCBA is composed of PCB substrate and electronic components assembled on its surface. 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 PCBA, extract metals for recycling and reuse. At present, the main schemes for the screening and classification of electronic single components separated from PCB substrates in various PCBA disman...
