Classifying and sorting production line for ABS and PP plastic fragments or particles

Abstract

The invention discloses a classifying and sorting production line for ABS and PP plastic fragments or particles. The classifying and sorting production line comprises an ABS sorting device and a PP guide groove. The ABS sorting device comprises an ABS settling pond, an ABS circulating pond and a pressure pump. The top of the ABS settling pond is provided with an opening and provided with an outflow opening lower than the opening. The ABS circulating pond is arranged below the ABS settling pond. An inlet of the pressure pump is communicated with the ABS circulating pond, and an outlet of the pressure pump is communicated with the ABS settling pond. The ABS settling pond and the ABS circulating pond are used for containing sodium chloride solutions with the concentration of 18% to 19.5%. Filter holes are formed in the inlet end of the PP guide groove and communicated with the outflow opening of the ABS settling pond, and the outlet end of the PP guide groove is lower than the inlet end of the PP guide groove. The filter holes of the PP guide groove are communicated with the ABS circulating pond.

Description

technical field [0001] The invention relates to a grading and sorting production line for ABS and PP plastic chips or granules. Background technique [0002] Recycling and recycling waste plastic bottles can not only make full use of resources, but also reduce production costs. At present, the plastics with higher prices mainly include polypropylene PP, polyethylene PE, polystyrene transparent GPPS, modified polystyrene ABS and high impact polystyrene HIPS. Since these types of plastic bottles and bottle caps are difficult to distinguish with the naked eye when recycling waste plastic bottles and mineral water bottles, so that after crushing, polypropylene PP, polyethylene PE, polystyrene permeable benzene GPPS, modified polystyrene ABS and high Impact polystyrene, HIPS, etc. are mixed together, and the prices of these types of plastic flakes or granules vary greatly, and the prices vary greatly. The prices of these types of plastic flakes or granules mixed together are far...

AI Technical Summary

Problems solved by technology

Since these types of plastic bottles and bottle caps are difficult to distinguish with the naked eye when recycling waste plastic bottles and mineral water bottles, so that after crushing, polypropylene PP, polyethylene PE, polystyrene permeable benzene GPPS, modified polystyrene ABS and high Impact polystyrene, HIPS, etc. are mixed together, and the prices of these types of plastic flakes or granules vary greatly, and the prices vary greatly. The prices of these types of plastic flakes or granules mixed together are far lower than their own prices. , leading to low economic efficiency
