Recycling device of waste plastic

Abstract

The invention belongs to the technical field of plastic recycling, and particularly discloses a recycling device of waste plastic. The recycling device comprises a cleaning unit, a power unit, a crushing unit and a feeding unit, wherein the cleaning unit comprises a cleaning tank, a hollow rotating shaft, a hemispherical screen, a jacking column and a limiting rod, the hemispherical screen is located above the cleaning tank and on the jacking column, and the jacking column penetrates through the bottom of the cleaning tank and is slidably connected in the cleaning tank; a strip-shaped groove is formed in the surface of the hollow rotating shaft, a feeding hole located above the cleaning groove is formed in the surface of the hollow rotating shaft, and a convex block which is connected to the strip-shaped groove in a sliding mode is arranged on the hemispherical screen; the power unit is used for driving the hollow rotating shaft to rotate; the crushing unit comprises a pressing plate and a grinding cylinder with openings at two ends, wherein the pressing plate is fixed at the lower part of the hollow rotating shaft and communicates with the hollow rotating shaft, and a pressing roller is rotationally connected to the bottom surface of the pressing plate; a rigid screen plate capable of being in contact with the pressing roller is arranged in the grinding cylinder; and the feeding unit is used for conveying an auxiliary agent to the upper part of the rigid screen plate. By means of the device, the waste plastic can be cleaned, dried and crushed, so that processing efficiencyis greatly improved.

Description

technical field [0001] The invention belongs to the technical field of recycled plastics, in particular to a recycling device for waste plastics. Background technique [0002] Polyethylene is a kind of thermoplastic resin obtained by polymerization of ethylene. In the plastic industry, polyethylene has the largest output, the widest application and the largest consumption. Therefore, a large amount of waste polyethylene is produced every year. Due to the molecular structure of polyethylene, polyethylene waste is difficult to degrade in the natural environment, causing pollution to the environment. With the continuous expansion of the polyethylene consumer market and the continuous increase and diversification of polyethylene consumer products, the amount of waste is also increasing. The recycling of waste polyethylene is the focus of waste plastic recycling. [0003] The main methods of waste disposal of polyethylene in my country are: (1) landfill; (2) incineration; (3) ch...
