The bottom side of the box cover 2 is rotatably connected to the rotating shaft 41, and a reduction motor 42 connected to the rotating shaft 41 is mounted on the upper side of the box cover 2. A disc 43 is fixed to the bottom end of the rotating shaft 41, and an inner cylinder 44 is fixed to the bottom side of the disc 43. The inner cylinder 44 and the outer cylinder 45 are provided with a plurality of through holes on their side walls. The outer cylinder 45 has a larger diameter than the inner cylinder 44. A material storage cavity is formed between the inner cylinder 44 and the outer cylinder 45. A feeding port 6 communicating with the material storage cavity is provided on the disc 43. A bottom plate 7 is fixed to the bottom side of the inner cylinder 44 and the outer cylinder 45. The bottom plate 7 is a tapered structure that gradually decreases from top to bottom. A water outlet 8 is installed at the water outlet in the middle of the bottom plate 7. A discharge pipe 9 communicating with the material storage cavity is installed on the bottom plate 7. A valve 10 is installed on the discharge pipe 9. The left and right sides of the inner cavity of the box body 1 are provided with a water blowing mechanism 5, which includes a fixing rod 51, a fixing pipe 52, a blowing head 53, a bellows 54, an air inlet pipe 55, an air pump 56 and an air delivery pipe 57. The left and right sides of the inner cavity of the box body 1 are fixed with a fixing pipe 52 through the fixing rod 51, and a plurality of air outlets are opened inside the fixing pipe 52, and the air outlets are installed with a blowing head 53. The left and right sides of the box body 1 are provided with a bellows 54, and the air inlet on the upper side of the bellows 54 is provided with an air inlet pipe 55, and the air outlet at the bottom of the bellows 54 is provided with a plurality of air outlets. An air pump 56 is installed at the bottom, and the air pump 56 is connected to the inner cavity of the fixed tube 52 through the air supply pipe 57. By setting the water-throwing mechanism 4 and adopting the centrifugal water-throwing method, the water on the surface of the plastic particles between the inner cylinder 44 and the outer cylinder 45 can be quickly thrown into the inner cavity of the box body 1. At the same time, by setting the water-blowing mechanism 5, the residual moisture on the surface of the plastic particles is further blown into the inner cavity of the outer cylinder 45 and discharged from the water outlet pipe 8 of the bottom plate 7.

The combination of water throwing and water blowing can quickly remove the water on the plastic particles, greatly improving the drying efficiency. By setting the heating pipe 11, the air in the bellows 54 can be heated, further improving the rate of water loss on the surface of the plastic particles.
