Recycling and recycling method of waste electronic components

Abstract

The invention discloses a method for recycling and reusing waste electronic elements, comprising the following four steps: firstly, carrying out a functional classification on electronic elements, anddirectly recycling the elements with functions to reuse and carrying out a material grade classification on the elements without functions; secondly, crushing the electronic elements without functions; thirdly, selecting and separating the crushed materials; and fourthly, recycling and reusing a metal enrichment body and a non-metal enrichment body. In the invention, classification and recycle are carried out according to the characteristics of the electronic elements through crushing, magnetically selecting, electrostatic separating and centrifugation separation, and the waste electronic elements can be recycled and reused in a resource utilization with high utilization of recycling and without secondary pollution.

Description

technical field [0001] The invention belongs to the technical field of recovery and reuse, and specifically refers to a method for recovery and reuse of waste electronic components. Background technique [0002] Electronic components are mainly found on the circuit boards of various household appliances such as televisions, refrigerators, air conditioners, personal computers, mobile phones, game consoles, radios, and tape recorders in daily life. At present, the commonly used components include resistors, capacitors, inductive components, electrical contacts, diodes, transistors, integrated circuits, etc., and each component can be divided into several types, such as resistors can be divided into metal film resistors resistors, glass glaze resistors, wirewound resistors, etc. It can be seen that there are many kinds of electronic components and contain many kinds of materials. Among these materials, such as lead, cadmium, bromide, etc., are harmful to the environment and h...
