Abstract

The invention discloses a device for producing regenerative polyester bottle chips by using waste plastics and a production process thereof. The device comprises a crush cleaning system, an electric conveying control system, a paper scrap separation system, a semi-finished collecting system, a finished metering sack sewing system, a polyester bottle chip quality detecting system and a sewage treatment system. The production process for producing the regenerative polyester bottle chips by using the waste plastics comprises sequentially passing the waste plastics through the following units: a selection unit, a crush unit, a conveying unit, a washing unit, a rinsing unit, a drying unit and a storage unit. The system of the embodiment of the invention can realize the recycling of waste plastic resources, solve the problem of white pollution caused by the waste plastics, make wastes profitable, and maximize economic and environmental-protection benefits. The device and the production process are continuous in production, so that the quality of regenerative products is stable, safe and reliable and downstream customers can use the regenerative products safely.

Description

technical field [0001] The invention belongs to the field of resource regeneration, and discloses a device for producing recycled polyester bottle flakes from waste plastics and a production process thereof. Background technique [0002] Raw polyester bottles are mainly made of raw polyester chips. The complete chemical name of polyester is polyethylene terephthalate (PET), which is mainly made of terephthalic acid (PTA) by cracking petroleum derivatives. ), and then react with ethylene glycol (EG) for esterification-polycondensation reaction to produce polyester chips, which are further processed into polyester bottles, polyester fibers and other polyester products. In daily life, there are many kinds of waste plastics. In addition to polyester materials, there are other materials such as: polyethylene (PE), polycarbonate (PC), acrylonitrile-butadiene-styrene copolymer (ABS), poly Plastic products made of styrene (PS), polyvinyl chloride (PVC), etc. There are plastic prod...
