Polyethylene (PE) bottle scrap production process

Abstract

The invention discloses a polyethylene (PE) bottle scrap production process. The process includes the following steps that a packaging bag of recycled bagged plastic bottles is automatically opened through an unpackaging machine; the plastic bottles taken out of the bag are classified and sorted; the sorted PE plastic bottles are conveyed through a plate chain feeding machine to a subsequent crushing procedure so as to be crushed; PE plastic scraps obtained after crushing are conveyed into a rinsing machine to be rinsed; rinsed crushed PE plastic scraps are conveyed into a high-speed friction machine behind to be further processed and broken; then the PE plastic scraps are rinsed again and subjected to a dehydration procedure; dehydrated PE bottle scraps are separated and sorted according to the colors through a color separation machine; and the PE scraps different in colors are conveyed to different packaging machines correspondingly to be packaged and delivered into a warehouse so as to be stored. According to the PE bottle scrap production process, the whole production process is simple, manual operation is convenient, the labor intensity is low, thus, the production and cleaning time is shortened, the cleaning efficiency is improved, the cost is reduced, and the economic benefits are high.

Description

[0001] Technical field: [0002] The invention relates to the field of resource recycling, in particular to a plastic bottle recycling process, in particular to a production process for PE bottle flakes. [0003] Background technique: [0004] Polyethylene (referred to as PE) is a thermoplastic resin obtained by polymerization of ethylene. In industry, it also includes copolymers of ethylene and a small amount of α-olefins. Polyethylene is odorless, non-toxic, feels like wax, has excellent low temperature resistance (the lowest operating temperature can reach -100-70°C), good chemical stability, and can resist most acids and alkalis (not resistant to oxidation) acid). Insoluble in common solvents at room temperature, low water absorption, excellent electrical insulation. More than half of high-pressure polyethylene is used for film products, followed by pipes, injection molding products, wire wrapping layers, etc. Medium and low-pressure polyethylene is mainly used for injec...

Problems solved by technology

[0005] In our country, because the recycling of PE bottles has just started, various technical research and equipment are relatively backward, and consumers do not know enough about the importance of recycling PE bottles, which leads to the inclusion of various wastes in the recycled PE bottles. The existing PE recycling The process has the following disadvantages: the cleaning effect is not good, the cleanliness of the plastic fragments obtained is not up to standard, and the cleaning cost is high
