[0036] The first plasma generator 121 separates the dust on the surface of the material transported through the feed pipe 120 from the material through electrostatic dust removal, so as to subsequently separate the plastic particles from the dust. The second plasma generator 131 is used to eliminate static electricity on the surface of the plastic particles to prevent static electricity from adsorbing dust, thereby ensuring that dust does not stick to the plastic particles during discharge.

[0037] Please continue reading Figure 1-3 The particle guide component 200 is connected to the housing 100 to guide the plastic particles and change their output direction, so that the dust particles contained in the plastic particles are subjected to the centrifugal force and deposited outward;

[0038] The particle guide component 200 includes a washing deck 1 210 screwed on the inner side of the machine body shell 100, and a washing deck 2 220 screwed on the inner side of the machine body shell 100 so that the particle output direction is sharply turned. The washing deck 1 210 and the washing deck 2 220 cooperate to form a guide channel, and also includes a particle limiting plate 230 screwed on the inner side of the machine body shell 100. The particle limiting plate 230 is arranged above the washing deck 1 210 and forms a particle guide channel (not marked in the figure) with the washing deck 1 210.

[0039] When the gas entrains the plastic particles into the housing 100, the gas is transported through the guide channel formed by the cooperation of the washing deck 1 210 and the washing deck 2 220, and a sharp change of direction occurs at the bend, so that the dust particles contained in the plastic particles are subjected to the centrifugal force and deposit outward to generate negative pressure. At this time, the dust particles are charged and move along the electric field direction of the electric line. Then, the dust particles are guided by the outlet guide plate 310 and acted on by the negative pressure, and then transported to the dust transport pipe 320, so that the dust particles and the plastic particles are separated;

[0040] The washing deck 1 210 is connected to the inner wall of the housing 100 in a trapezoidal shape, and the diversion channel formed is arranged corresponding to the position of the discharge pipe 130;

The dust conveying pipe 320 is connected to an air release valve 321, and the rear end of the dust conveying pipe 320 is connected to the external cyclone separator port.

[0044] Working principle: When the utility model is in use, the first plasma generator 121 separates the dust from the surface of the material transported through the feed pipe 120. When the gas entrains the plastic particles and the dust into the body shell 100, it is transported through the guide channel formed by the cooperation of the washing deck 1 210 and the washing deck 2 220. A sharp change of direction occurs at the bend, so that the dust particles contained in the plastic particles are subjected to the centrifugal force and deposit outward to generate negative pressure. After being guided by the air outlet guide plate 310 and the negative pressure, the dust particles are transported to the dust transport pipe 320, thereby realizing the separation of the dust particles and the plastic particles.

[0045] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention.
