Embodiment Construction

[0015] Refer to Figure 1 ~ Figure 2 , The device for separating plastic particles and dust with negative pressure wind power of the present invention includes a separator 1, an induced draft fan 2, and a dust collecting bag 3. The separator 1 is composed of a housing 11, an upper guide plate 12, and a lower The guide plate 13, the mixing inlet 14, the particle outlet 15, and the dust air duct 16. Among them, the shell 11 is made of stainless steel plate, connected up and down, and a rectangular funnel-shaped thin wall box; the upper edge of the shell 11 It is a rectangular mixing inlet 14 from the top view, the lower edge is regarded as a rectangle from the top, and the side is regarded as a particle outlet 15 that narrows from right to left; in the inner cavity of the shell 11: from the upper left edge to the center of the inner cavity, welded An upper guide plate 12 composed of a stainless steel plate with a slope of 40° downward to the upper edge; from the upper right edge ...

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 production of 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 device for separating plastic particles and dust in a plastic particle dust mixture by using wind power. Background technique [0002] When plastics are recycled and reused, waste plastic products need to be crushed, sorted, cleaned, and dried and then re-granulated; the prior art usually uses plastic shredders to smash waste plastics, and plastic shredders generate a lot of dust when smashing waste plastics , Dust is composed of dirt and small plastic fragments attached to waste plastics. Part of this dust is mixed in plastic particles, and part of it is flying around with the airflow generated by the grinder, making the working environment very harsh and endangering the health of operators; At the same time, the collected crushed materials must be sorted again to separate the useless and harmful dust from the useful plastic particles; therefore, the existing technology for crushing waste plast...
