Abstract

The invention discloses a crushing and sorting device for electronic waste recycling, and relates to the technical field of electronic waste disposal. The crushing and sorting device is mainly used for solving the problem of low manual sorting efficiency, and comprises a crushing mechanism and a sorting mechanism. The crushing mechanism is located above the sorting mechanism. The crushing mechanism comprises a crushing cylinder, a first motor, a rotating shaft, crushing knives and a metal sieve, and the sorting mechanism comprises a sorting cylinder, a sorting roller and electromagnets. Driving motors are installed on both sides of the bottom of the metal sieve, and discs are mounted on the end parts of output shafts of the driving motors. Connecting rods are hinged to the outer sides of the front end surfaces of the discs, and the other ends of the connecting rods are hinged to the bottom of the metal sieve. The crushing and sorting device is provided with the sorting mechanism, is capable of automatically completing continuous sorting work, has a high degree of automation, and improves the work efficiency; the driving motors, the discs and the connecting rods are arranged to drive the metal sieve to move up and down to enable electronic waste to be in fully contact with the crushing knives, the crushing efficiency is improved, and the up-down movement of the metal sieve can improve the screening efficiency.

Description

technical field [0001] The invention relates to the technical field of electronic waste treatment, in particular to a crushing and sorting device for recycling electronic waste. Background technique [0002] Electronic waste refers to electrical appliances or electronic equipment that are discarded and no longer used, mainly including household appliances such as refrigerators, air conditioners, washing machines, and televisions, and communication electronic products such as computers. E-waste needs to be handled carefully, and it is easy to cause environmental pollution. [0003] The metals contained in electronic waste, especially precious metals, are dozens or even hundreds of times that of natural mineral deposits, and the recycling cost is generally lower than mining natural mineral deposits. E-waste contains a lot of magnetic metals such as iron and iron alloys, which are usually manually selected for recycling, which is inefficient, labor-intensive, and difficult to ...
