[0023] refer to Figures 1 to 5The output end of the driving motor 201 passes through the inner cavity of the box body 1 through the output shaft and is fixedly connected to the drying drum 202. The stirring rod 203 and the spiral plate 204 are connected to the inner cavity of the drying drum 202 in an equidistant row. The front end of the heating box 301 passes through the inner cavity of the box body 1 to the front end of the box body 1. The ventilation slots 304 are arranged in an equidistant array at the top of the heating box 301. The electric fan 302 is installed at the front end of the heating box 301 in an equidistant array. The top of the box body 1 is fixedly connected with an exhaust duct 4. The right side of the box body 1 is respectively fixedly connected with a feed hopper 5 and a discharge guide plate 6. The feed hopper 5 is arranged in the opening of the drying drum 202, and the discharge guide plate 6 is arranged on the lower side of the opening of the drying drum 202.

[0024] The above scheme is adopted: through the setting of the stirring rod 203, the particle clusters can be broken up during the tumbling process of the plastic particles, so that the particles can be separated and dried better, thereby improving the working efficiency of the device.

[0027] Working principle:

[0028] When in use, the components of the device are operated and controlled through the PLC control panel. The cleaned plastic particles are put into the inner cavity of the drying drum 202 by the feed hopper 5, and the drying drum 202 is driven to rotate by controlling the driving motor 201. The plastic particles are tumbled by the rotation of the drying drum 202. During the tumbling process of the plastic particles, the agitating rod 203 is used to break up the clumped plastic particles. At the same time, the electric fan 302 is controlled to work to pump air into the inner cavity of the heating box 301, and the impurities in the air are filtered by the air filter element 303. The heat pipe 305 heats the air and blows the hot air into the inner cavity of the drying drum 202 through the ventilation slots 304, thereby drying the plastic particles. The plastic particles that are broken up and tumbled are heated more evenly, thereby drying them more quickly. After the plastic particles are dried, the driving motor 201 is controlled to flip, driving the drying drum 202 to rotate. The rotation of the drying drum 202 drives the spiral plate 204 to swing, thereby pushing the plastic particles to the discharge port of the drying drum 202 for discharge, and the discharged plastic particles are concentrated inwardly and contained through the discharge guide plate 6.

[0029] In summary: this drying device for the production of modified plastic particles solves the problem that in the actual use of existing equipment, wet plastic particles will clump together, resulting in uneven heating, slow drying rate and reduced work efficiency through the cooperation between various components.
