[0022] Please refer to Figures 1-7 As shown, the utility model is a drying device for plastic particles, including a drying box 1. Inside the drying box 1, a mixing rod 5 is installed. The upper end of the mixing rod 5 is connected to a first longitudinal push rod 6. The output end of the first longitudinal push rod 6 is connected to a fan blade 7. On the bottom surface of the drying box 1, there is an installation groove 2. Inside the installation groove 2, a stirring motor 3 is connected. The output end of the stirring motor 3 is connected to a driving shaft 4. One end of the driving shaft 4 is connected to the mixing rod 5. Below the drying box 1, a support plate 15 is installed.

The position below the cover board 10 is adapted to the exhaust port 9. The bottom end of the drying box 1 is fixedly connected to a vertical frame 21. The drying box 1 is supported and fixed by using the vertical frame 21. On the surface of the air outlet plate 19, there are several through holes. The diameters of the several through holes are all smaller than the particle size of the plastic particles, which is convenient for the extraction of the drying air and prevents the plastic particles with a particle size smaller than the aperture of the through holes from falling into the air guide pipe 18, avoiding the blockage of the air guide pipe 18.
[0023] The upper end of the drying box 1 is connected to a second longitudinal push rod 14. The output end of the second longitudinal push rod 14 is connected to the cover plate 8. When the second longitudinal push rod 14 is lifted, the cover plate 8 opens. When the second longitudinal push rod 14 expands and contracts, the cover plate 8 closes. On the outer peripheral side of the cover board 10, a sliding block 11 is connected. On the inner surface of the cover plate 8, there is a sliding groove 12. The sliding block 11 is slidably matched with the sliding groove 12. The cover board 10 can slide longitudinally by using the sliding block 11 to cooperate with the sliding groove 12 to open and close the exhaust port 9. The upper end of the exhaust port 9 is connected to a floating rod 13. The floating rod 13 is a telescopic structure. The top end of the floating rod 13 is connected to the cover board 10. The cover board 10 is made of plastic material. When the plastic particles are dried, the evaporated gas pushes the cover board 10 upward to discharge the water vapor.

At the bottom end of the drying oven 1 is connected a stirring motor 3, which drives the mixing rod 5 in the drying oven 1 to rotate through the drive shaft 4. The mixing rod 5 is used to stir and disperse the plastic particles to prevent adhesion between the particles and improve the drying efficiency of the plastic particles. At the bottom end of the drying oven 1 is also installed a dryer 17. The dryer 17 introduces drying air into the drying oven 1 through the air duct 18 in cooperation with the air outlet plate 19 to assist in drying the plastic particles. With the disturbing effect of the mixing rod 5, the operation adaptability is strong.
[0026] The upper end of the mixing rod 5 is connected to the first longitudinal push rod 6, and the top end of the first longitudinal push rod 6 is connected to the fan blade 7. While the mixing rod 5 is rotating, the fan blade 7 rotates synchronously with the mixing rod 5. The fan blade 7 generates turbulent air flow in the drying oven 1 to disturb the drying air generated by the dryer 17, so that the drying air is evenly diffused. At the same time, the evaporation efficiency of the water vapor in the plastic particles is improved, and the drying effect of the plastic particles is maintained.
