Waste plastic treatment system and waste plastic treatment method

Abstract

The invention discloses a waste plastic processing system and a waste plastic processing method, which relate to the technical field of waste plastic recycling and regeneration, so as to improve that the prior art water washing and granulation system cannot achieve good cleaning effect, and the obtained plastic particles are of poor quality. technical problem. The waste plastic processing system of the present invention includes a cleaning unit; the unit includes a first rinsing machine, a first friction cleaning machine, a second friction cleaning machine, a third friction cleaning machine and a second rinsing machine connected in sequence; Both the rotational speed and the rotational speed of the third friction washer are smaller than the rotational speed of the second friction washer. The invention can effectively improve the cleaning strength of waste plastics and the quality of the plastic particles, so as to improve the utilization value and resource utilization efficiency of the plastic particles. The invention also provides a method for treating waste and old plastics, which can significantly improve the quality of plastic particles, and treat and reuse the waste water generated by cleaning, so as to achieve the purpose of saving water and improve the utilization rate of water resources.

Description

technical field [0001] The invention relates to the technical field of recycling waste plastics, in particular to a waste plastics processing system and a waste plastics processing method. Background technique [0002] With the development of economy and society, plastic products are widely used in people's production and life. The plastic content in domestic waste is increasing, and the recycling and resource utilization of waste plastics has become a hot issue. However, it is difficult to clean waste plastics in domestic garbage, and the cleaning cost is high. The deep cleaning of waste plastics has become the core issue affecting its resource utilization. [0003] At present, the water washing and granulation system of waste plastics in the prior art usually includes a friction cleaning machine, a rinsing tank, a cutting compactor, a single-screw extruder and a granulator arranged in sequence, and the waste plastics after crushing first enter the friction cleaning The ...
