Problems solved by technology

[0002] When plastics are recycled and reused, waste plastic products need to be crushed, sorted, cleaned, dried, and then re-granulated; in the prior art, plastic shredders are usually used to crush waste plastics, and plastic shredders will generate a lot of dust when crushing waste plastics , Dust is composed of soil dirt and fine plastic fragments attached to waste plastics. Part of these dusts are mixed in plastic particles, and some of them are diffused with the airflow generated by the pulverizer, making the working environment very bad and endangering the health of operators; At the same time, the collected pulverized materials must be sorted again to separate the useless and harmful dust from the useful plastic particles; Low efficiency problems and deficiencies

Abstract

The invention discloses a separation device of plastic particles and dust by negative-pressure air power, which comprises a separator (1), a draft fan (2) and a dust-collecting bag (3). The device comprising the separator (1), the draft fan (2) and the dust-collecting bag (3) adopts the technical scheme of sucking dust and separating plastic particles and dust by utilizing negative-pressure air power and overcomes the problems and the defects of great dust danger, high labor cost for secondary separation and low production efficiency of the prior art. The device is arranged at a discharging hole of a plastic pulverizer, finishes the crushing and separating procedures of plastics by one step and blows the dust into the dust-collecting bag to prevent the dust from flying, and the productionof crushing and recycling plastics reaches the aims of no dust escape, working environment purification, procedure simplification, labor cost reduction and production efficiency improvement.

Description

technical field [0001] The invention relates to a sorting machine, in particular to a negative-pressure wind-powered separation device for plastic particles and dust in a mixture of plastic particles and dust by using wind force to separate the plastic particles from the dust. Background technique [0002] When plastics are recycled and reused, waste plastic products need to be crushed, sorted, cleaned, dried, and then re-granulated; in the prior art, plastic shredders are usually used to crush waste plastics, and plastic shredders will generate a lot of dust when crushing waste plastics , Dust is composed of soil dirt and fine plastic fragments attached to waste plastics. Part of these dusts are mixed in plastic particles, and some of them are diffused with the airflow generated by the pulverizer, making the working environment very bad and endangering the health of operators; At the same time, the collected pulverized materials must be sorted again to separate the useless ...
