Regenerated PE material production technology

Abstract

The invention discloses a regenerated PE material production technology. The regenerated PE material production technology comprises the following steps that feeding is carried out; label blowing is carried out, and an axial flow fan is used for blowing out; sorting and feeding are carried out; wet smashing is carried out; crushed PE bottle sheets are transported into a feeding machine; gravity rinsing is carried out; the PE bottle sheets obtained after gravity rinsing are sent into the feeding machine; PE materials with water are subjected to high-speed friction, waste water generated by thehigh-speed friction process enters a sewage treatment station to be treated; thorough rinsing is carried out; the PE bottle sheets obtained after thorough rinsing are conveyed into the feeding machineto be subjected to centrifugal dewatering; the PE bottle sheets obtained after centrifugal dewatering have other colors, and optical physical sorting is used for sorting out finished products in theformulated color to be packaged and processed; ingredients obtained after color sorting enter a pelletizer to be subjected to prilling according to the regulated size; checking and packaging are carried out; and finished product PE particles are obtained. The PE material production technology is simple in project, manual operation is convenient, the washing time is short, the washing efficiency ishigh, the effect is good, meanwhile, water resources are sufficiently circulated and used, energy conservation and environment protection are achieved, cost is saved, economical and social benefits are high, and the regenerated PE material production technology is suitable for large-scale production and recovering.

Description

technical field

[0001] This application relates to the field of recycling waste resources, in particular to a production process for recycled PE materials. Background technique

[0002] PE (polyethylene) is one of the most widely used general-purpose plastics. The amount of imported and domestic PE plastics used in my country is about 4.4 million tons each year. Since plastic raw materials are chemically synthesized raw materials, they cannot be decomposed naturally, especially once The visual pollution caused by non-toxic plastic packaging waste and plastic film being discarded by people at will, resulting in "white pollution". The potential harm of waste plastics to the environment has attracted widespread attention from relevant government departments and society.

[0003] Judging from the data reports, foreign PE plastic (polyethylene) waste, if it is easy to separate relatively pure products, recycling is mainly based on mechanical regeneration. The recycling and recycl...
