[0021] Please see Figures 1-4 As shown, a drying device for processing plastic granules includes a positioning shell 1 and a support leg 2 fixed to the surface of the positioning shell 1. A connecting shell 3 is fixedly connected to the top of the positioning shell 1, and a feeding shell 4 is fixedly connected to one side of the top of the connecting shell 3. A drying shell 5 is fixedly connected inside the positioning shell 1, which facilitates the storage of plastic granules. A discharge pipe 6 is fixedly connected to the front and rear sides of the bottom of the drying shell 5 through a solenoid valve. A solenoid valve is provided on the surface of the discharge pipe 6 to facilitate the discharge of dried granules. A linkage device 7 is fixedly connected to one side of the connecting shell 3. The linkage device 7 can prevent blockage during feeding and can also stir the plastic granules to ensure uniform drying. The linkage device 7 includes a DC motor 701. A limit groove 8 is opened on one side of the positioning shell 1. A filter plate 16 is fixedly connected to the bottom of the inner cavity of the positioning shell 1. The filter plate 16 can screen out two different specifications of plastic granules, separating granules of different sizes and shapes to ensure the uniformity of the granules.

[0022] Four fixed shells 9 are fixedly connected to the surface of the positioning shell 1. A first fan 10 is fixedly connected inside the fixed shell 9. The fixed shell 9 facilitates the installation of the first fan 10. The first fan 10 can assist in cooling and drying the dried plastic particles when they fall onto the filter plate 16. Reinforcing blocks 11 are fixedly connected to both sides of the fixed shell 9. By fixing the reinforcing blocks 11 to the positioning shell 1, the connection strength between the fixed shell 9 and the positioning shell 1 can be improved. One side of the reinforcing block 11 is fixedly connected to the positioning shell 1.

[0023] A second fan 12 is fixedly connected between the top of the two sides inside the drying shell 5 and the positioning shell 1. The second fan 12 can guide the airflow inside the drying shell 5 to assist in drying the particles. The baffle 13 can prevent the particles from falling from the connecting shell 3 into the second fan 12. The baffle 13 is fixedly connected to the two sides of the top of the drying shell 5. A heating device 14 is fixedly connected to the surface of the drying shell 5. The heating device 14 can heat the heat-conducting copper pipe 15, thereby raising the temperature inside the drying shell 5. It should be noted that the heating device 14 and the heat-conducting copper pipe 15 mentioned above are all devices with relatively mature existing technology. The specific model can be selected according to the actual needs, which will not be elaborated here. The heat-conducting copper pipe 15 is installed inside the heating device 14.

[0024] A DC motor 701 is fixed to one side of the connecting housing 3. The output end of the DC motor 701 extends into the interior of the connecting housing 3 and is fixedly connected to a transmission rod 702. A spiral conveying blade 703 is fixedly connected to the surface of the transmission rod 702. A first transmission wheel 704 is fixedly connected to the end of the transmission rod 702 away from the DC motor 701. A transmission belt 705 is fitted onto the surface of the first transmission wheel 704. A second transmission wheel 706 is connected to the side of the transmission belt 705 away from the first transmission wheel 704. A drive rod 707 is fixedly connected to one side of the second transmission wheel 706. First, turning on the DC motor 701 causes the transmission rod 702 to drive the spiral conveying blade 703 to rotate, thereby uniformly feeding the plastic granules. When the transmission rod 702 rotates, it drives the first transmission wheel 704 to rotate. The rotation of the first transmission wheel 704 drives the transmission belt 705 to rotate. As the transmission belt 705 rotates, it causes the second transmission wheel 706 to rotate. At this time, the second transmission wheel 706 drives the drive rod 707 to rotate. As the drive rod 707 rotates, it drives the first transmission wheel 706 to rotate. The bevel gear 708 meshes with the second bevel gear 709 to rotate. At this time, the second bevel gear 709 drives the connecting rod 710 to rotate within the support plate 711. As the connecting rod 710 rotates, it drives the stirring rod 712 to rotate, thereby disrupting the plastic granules for easier drying. Furthermore, the scraper 713 adheres to the bottom of the drying shell 5's inner cavity, preventing granule accumulation and improving the uniformity of plastic granule drying. The end of the drive rod 707 away from the second transmission wheel 706 extends into the positioning shell 1. A first bevel gear 708 is fixedly connected to one side of 707. A second bevel gear 709 is meshed with one side of the first bevel gear 708. A connecting rod 710 is fixedly connected to the top of the second bevel gear 709. The top of the connecting rod 710 extends through the interior of the drying shell 5 and is rotatably connected to a support plate 711 via a bearing. Both sides of the support plate 711 are fixedly connected to the inner wall of the drying shell 5. Multiple sets of stirring rods 712 are fixedly connected to the surface of the connecting rod 710. A scraper 713 is fixedly connected to the bottom of the surface of the connecting rod 710.

[0025] Working principle: First, plastic granules are poured into the interior of the connecting shell 3 through the feeding shell 4. Then, turning on the DC motor 701 causes the transmission rod 702 to drive the spiral conveyor blade 703 to rotate, thus evenly feeding the plastic granules into the interior of the drying shell 5. At this time, the heating device 14 is turned on to heat the heat-conducting copper pipe 15, and the second fan 12 guides the airflow into the interior of the drying shell 5. When the transmission rod 702 rotates, it drives the first transmission wheel 704 to rotate. The rotation of the first transmission wheel 704 drives the transmission belt 705 to rotate. As the transmission belt 705 rotates, it causes the second transmission wheel 706 to rotate. At this time, the second transmission wheel 706 drives the drive rod 707 to rotate. As the drive rod 707 rotates, it... The first bevel gear 708 is driven to mesh with the second bevel gear 709 to rotate. At this time, the second bevel gear 709 will drive the connecting rod 710 to rotate within the support plate 711. As the connecting rod 710 rotates, it will drive the stirring rod 712 to rotate, thereby disturbing the plastic granules for drying. The scraper 713 is attached to the bottom of the inner cavity of the drying shell 5 to prevent the granules from accumulating, thereby improving the uniformity of drying the plastic granules. After drying is completed, the solenoid valve is opened to let the granules fall onto the filter plate 16 through the discharge pipe 6. At the same time, the first fan 10 is turned on to assist in cooling and drying the granules. At this time, the filter plate 16 can separate granules of different sizes and shapes, ensuring the uniformity of the granules before discharge.
