Assembly line type energy-saving and environmentally-friendly utilization method for waste plastic and assembly line for method

Abstract

The invention belongs to an assembly line type energy-saving and environmentally-friendly utilization method for waste plastic and an assembly line for the method. The method is characterized in thatthe waste plastic is processed and recycled in a processing plant in a centralized manner, assembly line type treatment and reutilization specifically comprises the steps of carrying out material sorting, crushing, decomposing and cleaning, dehydrating, drying, color sorting, storage, hot melting and injection molding on the waste plastic, and pollutants generated in each process are subjected toenvironmentally-friendly treatment on site. The production line is composed of a material sorting and crushing system, a material decomposing and cleaning system, a material dehydrating, drying and color sorting system, a material hot-melting, storing and forming system and a purification environmentally-friendly system. The method has the advantage that the waste plastic can be subjected to assembly line type energy-saving and environmentally-friendly treatment. The assembly line has the advantages that the design is reasonable, the mechanization level is high, the treatment cost is low, thetime and the labor are saved, the energy is saved, the environment is protected, and the use effect is good.

Description

technical field [0001] The invention belongs to an assembly line energy-saving and environment-friendly utilization method of waste plastics and an assembly line thereof. Background technique [0002] At present, the processing of recycled waste plastics, such as waste plastic bottles, plates, and other plastic products, is mostly carried out at recycling stations. Usually, manual sorting, sorting, cleaning, and crushing are used to transport them to plastic products factories for recycling. use. This traditional method of processing waste plastics is not only time-consuming, labor-intensive, slow in speed, poor in sorting and sorting quality, and low in production efficiency; it also pollutes the environment heavily. For example, some recycling stations use lye and rinsing water to clean the dirt in waste plastics during the cleaning process, and then dump the waste water at will, polluting the environment and groundwater sources. When waste plastics are processed, the du...

AI Technical Summary

Problems solved by technology

This traditional method of processing waste plastics is not only time-consuming, labor-intensive, slow, the quality of sorting and classification is poor, and the production efficiency is low; it also causes serious environmental pollution.

If some recycling stations use lye and rinse water during the cleaning process to clean the dirt in waste plastics, and then dump the waste water at will, polluting the environment and groundwater sources

During the processing of waste plastics, the dust generated is scattered in the air, causing air pollution

[0003] Even if the processed waste plastics are recycled and reused in the plastic products factory, there will be a large amount of dust and odor generated by heating the plastics, which will spread in the air and cause air pollution, and the processing process consumes a lot of energy and the heat recovery utilization rate is low.
