Such as televisions, refrigerators, air conditioners and other electronic products, especially the casing, in addition to metal components, the main part is plastic. the

Metal components are made of metal materials, and the metal components of most electronic products are made of non-ferrous metals. Non-ferrous metals are precious non-renewable resources, and their waste must be recycled to achieve regeneration and recycling. the

The raw material for producing plastics is mainly petroleum, and petroleum resources are limited. According to information, the world's plastic production in 2013 has reached 300 million tons, how much oil resources will be consumed! In addition, statistics show that in the global solid waste, the proportion of waste plastics has exceeded 10%, and it is still rising. The molecular structure of waste plastic products is strong, and the decomposition rate is extremely slow under natural conditions. It not only occupies the land and oceans that are piled up, but also pollutes soil, groundwater, and sea water, which is very harmful. Therefore, waste plastics also need to be recycled to realize regeneration and recycling. the

A Chinese patent discloses a method and equipment for recycling waste plastics (publication number CN102717451A, application number 201210228475.7), in which the cleaning and separation system includes a clear water tank, a sinking conveyor belt, a brine tank, a screw discharger, a screw conveyor Float hoist. The trough is a horizontal trough, and a sinking conveyor belt is installed at the bottom of the trough, and a screw discharge machine is also installed to connect with the sinking conveyor belt to send the sinking material out. The equipment is complicated, bulky, and occupies a large area. High consumption. the

At present, the sorting method of waste plastics for electronic products (mainly referring to casings) is generally carried out step by step. For some large electronic products (mainly referring to casings) waste plastics processing stations, one method is to facilitate manual selection to obtain casings. The mixed materials (including metal components, PS, ABS and PP) are sorted according to metal materials, environmentally friendly PS, flame-retardant materials, and mixed materials. Among them, the flame-retardant material is flame-retardant PS , Flame-retardant mixture of flame-retardant ABS and flame-retardant PP, the mixture is a mixture other than metal, environmentally friendly PS and flame-retardant materials. Since metal materials, environmentally friendly PS, flame-retardant materials, and mixed materials have large differences in density, they can be sorted according to density differences (salt water tank). However, the existing system is complex, bulky, occupies a large area, and consumes a lot of energy. the
