Problems solved by technology

[0006] Flotation sorting is used to sort waste plastic fragments, which is inefficient and expensive
For waste plastic fragments with a density greater than water, halogen salt solution is usually used as a flotation medium for flotation cleaning. The used flotation medium is difficult to handle and will pollute the environment after discharge.

Embodiment Construction

[0041] The present invention will be further described in detail in conjunction with the accompanying drawings and specific embodiments.

[0042] figure 1 The swirl-type waste plastic crushing, sorting and cleaning system shown includes: a feeding mechanism, a crusher, a screw elevator, a flotation tank, and multiple (two in this example) ) A cyclone sorting and cleaning device connected in series.

[0043] The feeding mechanism is a belt conveying feeding mechanism.

[0044] The shredder is an existing plastic shredder, which cuts waste plastics into waste plastic fragments.

[0045] The screw elevator is located between the crusher and the flotation tank. Or place the crusher high on the flotation tank, and use gravity to drop the broken pieces into the flotation tank.

[0046] The flotation cell is a linear launder, the outlet of the flotation cell is located at one end of the flotation cell, and the feed port of the flotation cell is located at the other end of the flo...

Abstract

The invention relates to a cyclone-type waste plastic crushing, sorting, and washing system. Along a material delivery direction, the system comprises the following components arranged sequentially: a crusher used for crushing waste plastic, a flotation tank used for sorting waste plastic pieces according to density differences of flotation medium and the waste plastic pieces; and one or more than two serially connected cyclone sorting and washing devices used for carrying out cyclone sorting and waste plastic piece washing through a fluid medium. The invention also relates to a cyclone-type waste plastic crushing, sorting, and washing method. According to the system and the method, the structure is simple, waste plastic treatment process continuity and automation are realized, treatment efficiency and treatment effect are effectively improved, and waste plastic automatic sorting and washing are realized. The system and the method belong to the technical field of waste plastic recovery.

Description

technical field [0001] The invention relates to the technical field of recycling waste plastics, in particular to a swirl-type waste plastics crushing, sorting and cleaning system and method. Background technique [0002] With the increasing consumption of plastic products, waste plastics are also increasing. If these waste plastics are not handled properly, they will inevitably damage the environment, destroy the ecological balance, and ultimately threaten the survival of human beings. [0003] Existing waste plastics are mainly processed in the following ways: after waste plastics are recycled, they are first classified, broken into pieces, cleaned, and then melted to make new plastic raw material particles and finished products for recycling. [0004] In the existing equipment, there is no cyclone-type waste plastic crushing, sorting and cleaning system. [0005] Generally, a crusher is used to crush waste plastics into waste plastic fragments. [0006] Flotation sorti...
