Abstract
Description
Technical Field
[0001] This utility model belongs to the field of dehydrator technology, specifically relating to a structure for drying plastic granules. Background Technology
[0002] Currently, the plastics processing industry commonly uses underwater pelletizers to produce plastic pellets. The molten material at high temperature is extruded through the die head orifice under the pressure of the screw. The extruded strip material is cut into pellets by a high-speed rotating cutter that is close to the die surface. The pelletizing cutter is in close contact with the die surface. After the pellets are cut off, they are thrown away from the cutter by centrifugal force and transported to cooling water. Then, along with the cooling water, they are transported to a dewatering dryer for dehydration, so that the water and pellets are separated.
[0003] Existing spin dryers are not convenient for continuous processing, have low working efficiency, and require adjustments to the spin time due to the varying difficulty of spin drying plastic granules, causing inconvenience. Utility Model Content

A vertical support arm is fixedly provided on one side of the support plate and the top of the support arm is connected to the outer cavity through a rotating shaft. A first sliding groove is provided on the other side of the support plate. A sliding arm is slidably provided on the first sliding groove. The sliding arm is perpendicular to the support plate and its length is greater than that of the support arm. A threaded rod is provided through the first sliding groove and passes through the threaded hole of the sliding arm. The top of the sliding arm is slidably connected to the outer cavity through the sliding groove mechanism.
[0006] Preferably, the driving mechanism of the outer cavity includes a motor located at the rotating cylinder. A gear ring is fixedly provided on the outer wall of the rotating cylinder. A drive gear is connected to the output end of the motor, and the drive gear meshes with the gear ring.
[0007] Preferably, a screen is provided on the side of the fixed cavity away from the rotating cylinder, a motor is fixedly provided at the opening of the outer cavity on this side, and a circumferential array of ventilation openings is provided on the other side of the outer cavity.
[0008] Preferably, the outer wall of the outer cavity is provided with a second sliding groove at the sliding arm, and side rails are provided on both sides of the second sliding groove.

[0009] The beneficial effects of this utility model are: simple structure, continuous drying of plastic granules through the horizontal spin-drying drum, high working efficiency, and the tilt of the spin-drying drum can be adjusted according to the drying speed of the plastic granules, making it highly practical, as detailed below: (1) The present invention is provided with an outer cavity. The inclination of the outer cavity is adjusted according to the drying speed of the plastic particles to change the speed at which the plastic particles pass through the drying cylinder. By rotating the threaded rod, the sliding arm is pushed to slide on the first slide groove. Since the lengths of the support arm and the sliding arm are different, when the sliding arm moves, the outer cavity rotates around the pivot on the support arm to change its inclination angle. When the device is working, the plastic particles enter the fixed cavity from the feed pipe and slide down from the fixed cavity to the drying cylinder. The drying cylinder is driven to rotate by the rotating cylinder to spin water off the plastic particles inside, so as to achieve uninterrupted operation.
[0010] (2) This utility model is equipped with a fan. When the spin dryer is rotating, the fan supplies air into the outer cavity. The airflow drives the air to pass through the plastic particles, which accelerates the evaporation of water and discharges it from the vent, thereby improving the working efficiency. The airflow can also cool the two annular grooves, preventing the temperature of the annular grooves from becoming too high due to continuous operation. Attached Figure Description

A drive mechanism is located on the side of the spin-drying cylinder 6 within the outer cavity 1. The drive mechanism includes a motor 15, which is located at the rotating cylinder 16. A gear ring 13 is fixedly disposed on the outer wall of the rotating cylinder 16. A drive gear 18 is connected to the output end of the motor 15. The drive gear 18 meshes with the gear ring 13. The rotation drives the gear ring 13 to rotate, and the spin-drying cylinder 6 rotates accordingly. One side of the discharge cylinder 7 is rotatably connected to the first annular groove 9 at the opening of the outer cavity 1 through an external rotating ring. The other side of the outer cavity 1 is provided with a fixed cavity 12, and one side of the fixed cavity 12 is provided with a second annular groove 17. The rotating cylinder 16 is inserted into the second annular groove 17 and rotatably connected to it. The upper side of the fixed cavity 12 is fixedly provided with a feed pipe 5 that passes through the outer cavity 1, and its outer wall is fixedly connected to the outer cavity 1. Plastic particles enter the fixed cavity 12 from the feed pipe 5 and slide down from the fixed cavity 12 into the spin-drying cylinder 6.
[0017] See Figure 1 , 2 4. A support plate 2 is provided below the outer cavity 1. A vertical support arm 3 is fixedly provided on one side of the discharge cylinder 7. The top end of the support arm 3 is connected to the outer cavity 1 through a rotating shaft. A first sliding groove 10 is provided on the other side of the support plate 2. A sliding arm 4 is slidably provided on the first sliding groove 10. The sliding arm 4 is perpendicular to the support plate 2 and its length is greater than that of the support arm 3, so that the outer cavity 1 is in an inclined state. A threaded rod 11 is passed through the first sliding groove 10. The threaded rod 11 passes through the threaded hole 22 of the sliding arm 4. By rotating the threaded rod 11, The sliding arm 4 is pushed to slide on the first slide groove 10.

It can continuously spin-dry plastic granules through the horizontal spin-drying cylinder, which has high working efficiency. Moreover, the inclination of the spin-drying cylinder can be adjusted according to the spin-drying speed of the plastic granules. It is highly practical and suitable for promotion.
[0020] For specific usage, please refer to... Figure 1-4 The inclination of the outer cavity 1 is adjusted according to the drying speed of the plastic granules to change the speed at which the plastic granules pass through the spin-drying cylinder 6. By rotating the threaded rod 11, the sliding arm 4 is pushed to slide on the first slide groove 10. Since the lengths of the support arm 3 and the sliding arm 4 are different, when the sliding arm 4 moves, the outer cavity 1 rotates around the pivot on the support arm 3 to change its inclination angle. When the device is working, the plastic granules enter the fixed cavity 12 from the feed pipe 5 and slide down from the fixed cavity 12 to the spin-drying cylinder 6. The spin-drying cylinder 6 is driven to rotate by the rotating cylinder 16 to spin water off the plastic granules inside. When the spin-drying cylinder 6 is rotating, the fan 14 supplies air into the outer cavity 1. The airflow drives the air to pass over the plastic granules, accelerates the evaporation of water, cools the two annular grooves, and discharges the water from the vent 8. The device operates continuously.
