Description

Technical Field

[0001] The utility model relates to the technical field of plastic recycling, in particular to a plastic pyrolysis recycling device. Background Art

[0002] Thermoplastic plastic products and thermosetting plastic products have the advantages of flexible design, easy molding, light weight, high strength, and corrosion resistance. With the continuous increase in production, the amount of plastic product waste has increased dramatically, and the amount of scraps and waste generated during the production and processing of plastic products is even greater. Existing technologies usually use landfill, incineration and other methods to treat plastic product waste, but these methods are prone to cause land loss and secondary environmental pollution, with high processing costs and limited processing capacity. For this reason, common plastics are recycled to reduce environmental pollution while achieving further resource utilization.

[0003] In recent years, in order to reduce environmental pollution, existing technologies have begun to use pyrolysis and recycling processing of plastic products. Pyrolysis refers to the conversion of plastic product waste into gas at high temperature, which is condensed to form oily organic compounds with different structures. The residue in the pyrolysis can be reused after treatment. The oily substance can be used as fuel oil or further processed into chemical raw materials for making plastic products. However, in actual use, the overall structure of existing plastics is relatively large before hot melting, and the hot melting difficulty is relatively high. It is easy to agglomerate and difficult to dissolve. The shredding and crushing capacity before hot melting is insufficient, and the metal and dust processing capacity in the plastic is relatively insufficient, which increases the difficulty of hot melting and the hot melting quality is relatively poor. For this reason, we propose a plastic pyrolysis recovery device to solve the above problems. Utility Model Content
