[0017] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0018] like Figure 1-5 As shown, a plastic granule dryer includes a cylindrical body 1 with openings at both ends. A conical mesh cover 2 is installed inside the cylindrical body 1, near the lower end of the cylindrical body 1. An air duct 3 is connected to the lower opening of the cylindrical body 1, and a main pipe 4 is rotatably connected to the other end of the air duct 3. An electrical box 5 and an electric heating element 6 are installed on the main pipe 4, and a fan 7 is installed at the other end of the main pipe 4. The dryer also includes a base plate 8, on which a support frame 9 for supporting the electrical box 5 is installed. The outer surface of the cylindrical body 1 is... There is a clamp 10, and a fixed shaft 11 is provided at one end of the clamp 10. A vertical plate 12 is provided on the base plate 8. The fixed shaft 11 passes through the vertical plate 12 and is rotatably connected to the vertical plate 12. A mounting cavity 13 is provided on one side of the upper end of the vertical plate 12. A worm gear 14 is provided on the fixed shaft 11. The worm gear 14 is located inside the mounting cavity 13. A worm 15 that cooperates with the worm gear 14 is provided inside the mounting cavity 13. A handwheel 16 is provided at one end of the worm 15. The handwheel 16 is located outside the mounting cavity 13.

[0019] When drying plastic, a fixed amount of plastic granules is first fed into the cylinder 1 through the opening at the top. The particle size of the plastic granules is larger than the aperture of the mesh cover 2, so the plastic granules cannot pass through the mesh cover 2. After the fixed amount of plastic granules is fed into the cylinder 1, the fan 7 and the electric heating tube 6 are started to transport the outside air to the bottom of the cylinder 1 through the main pipe 4 and the air duct 3. Since the air is heated after passing through the electric heating tube 6, the heated air entering the cylinder 1 will dry the plastic granules in the cylinder 1. At the same time, the air will be discharged through the opening at the top of the cylinder 1. Since there are gaps between the plastic granules, the air can pass through the gaps between the plastic granules.

[0020] After the plastic granules in the cylinder 1 have dried, the blower 7 stops working with the heating element 6, and then the handwheel 16 is turned. The handwheel 16 drives the worm gear 15 to rotate. Through the cooperation of the worm gear 15 and the worm wheel 14, the fixed shaft 11 is driven to rotate. Then, the fixed shaft 11 drives the clamp 10 and the cylinder 1 to rotate, controlling the cylinder 1 to rotate 180° so that the upper opening of the cylinder 1 faces downward. At this time, the plastic granules in the cylinder 1 can be discharged from the cylinder 1 under the action of gravity. The workers can then bag and remove the discharged plastic granules. At the same time as the plastic granules in the cylinder 1 are being poured out, the blower 7 can be started to blow external air into the mesh cover 2 and the inside of the cylinder 1, so that the remaining plastic granules in the cylinder 1 can be discharged from the cylinder 1. Both ends of the cylinder 1 are conical to ensure that the plastic granules in the cylinder 1 can be discharged smoothly.

[0021] The duct 3 and the main pipe 4 are connected by a bearing, and a cover is fitted on the outer surface of the connection between the two to reduce the loss of hot air.

[0022] Both the electric heating element 6 and the electrical box 5 are existing technologies. The electrical box 5 can be used to control the operation of the electric heating element 6 and the fan 7.

[0023] Furthermore, a sleeve 17 is rotatably connected to the upper opening of the cylinder 1. The sleeve 17 is fixed to the cylinder 1 by a locking fastener. Both ends of the sleeve 17 are provided with partitions 18 with through holes. Inside the sleeve 17, between the two partitions 18, a filter element 19 is provided. When drying plastic granules, the filter element 19 can filter out dust and impurities discharged with the flowing air, thereby reducing pollution to the working environment. At the same time, it can also seal the upper opening of the cylinder 1 to prevent external impurities from entering the cylinder 1. When it is necessary to discharge the plastic granules inside the cylinder 1, simply open the locking fastener, and the plastic granules inside the cylinder 1 will be discharged from the cylinder 1 to the outside under the action of gravity.

[0024] Furthermore, a reinforcing connector 20 is provided between the duct 3 and the clamp 10, which can improve the stability of the duct 3.

[0025] Furthermore, both duct 3 and main pipe 4 are metal pipes.

[0026] Furthermore, a surrounding plate 21 is provided on the upper surface of the base plate 8. The surrounding plate 21 forms a material trough for accommodating plastic granules between the base plate 8 and the upright plate 12. The plastic granules in the cylinder 1 can be directly poured into the material trough. When drying the newly added plastic granules in the cylinder 1, the plastic granules in the material trough are transferred out, thereby saving time and improving work efficiency.
