Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Reference Figures 2-4This utility model provides an embodiment of a plastic granule drying and stirring device, including a barrel 1. The barrel 1 is designed for drying plastic granules. A discharge hole is provided on the lower side of the barrel 1. The barrel 1 is mounted by a bracket, etc. (not shown in the prior art). A motor 3 is fixedly connected to the upper end of the barrel 1. The operation of the motor 3 drives the rotating shaft 12 to rotate. A filter frame 10 is fixedly connected to the inner wall of the barrel 1. The filter frame 10 has a through hole for drainage during plastic granule drying. A second motor is fixedly connected to the bottom end of the filter frame 10. 16. The operation of motor 16 drives the rotating plate 15 to rotate and adjust its position. The rotating plate 15 is rotatably connected to the bottom inner wall of the filter frame 10. When the through groove on the rotating plate 15 coincides with the through groove on the filter frame 10, the plastic particles inside the filter frame 10 are discharged from the filter frame 10. When the through groove on the rotating plate 15 rotates into the filter frame 10, it closes the through groove of the filter frame 10. Two symmetrical through grooves are opened on the upper inner wall of the rotating plate 15. The through grooves opened in the rotating plate 15 and the through grooves opened in the filter frame 10 are of the same size. The bottom inner wall of the rotating plate 15 is fixedly connected to the output shaft of the second motor 16. A rotating shaft 12 is rotatably connected through and to the upper inner wall of the barrel 1. The upper inner wall of the rotating shaft 12 is fixedly connected to the output shaft of the first motor 3. The rotating shaft 12 rotates due to the operation of the first motor 3. The rotation of the rotating shaft 12 drives the auger 14 and the stirring plate 13 to rotate. A stirring plate 13 is fixedly connected to the outer wall of the rotating shaft 12. The rotation of the stirring plate 13 agitates the plastic particles inside the filter frame 10. Two stirring plates 13 are provided. Mixing plates 13 are respectively arranged on both sides of the auger 14. The auger 14 is fixedly connected to the outer wall of the mixing plate 13. The auger 14 moves the plastic particles on the lower side to the upper side by rotating the shaft 12. A drying component is provided at the upper end of the barrel 1. The drying component is used to dry the plastic particles. A switching component is fixedly connected to the lower outer wall of the barrel 1. The switching component is used to change the feeding port. A feed pipe 4 is fixedly connected to the upper end of the barrel 1. The feed pipe 4 is used to inject the plastic particles to be dried into the filter frame 10.
[0033] Reference Figure 1 and Figure 5The switching assembly includes a fixing plate 9, which provides support for the movement of the sliding plate 17. A through hole is provided on the upper side of the fixing plate 9. The upper end of the fixing plate 9 is fixedly connected to the lower outer wall of the barrel 1. The sliding plate 17 is slidably connected to the lower inner wall of the fixing plate 9. The sliding plate 17 is fixed in position by an insert 5. A first discharge connector 7 is provided on the sliding plate 17 for connecting to a drainage pipe. A second discharge connector 8 is provided on the sliding plate 17 for connecting to a discharge pipe, used for drying plastic granules. Output: A block 5 is elastically connected to the front outer wall of the fixing plate 9 via a spring 6. The rear side of the block 5 is engaged with the inner wall of the slide plate 17 to fix the position of the slide plate 17. Once the block 5 leaves the inner wall of the slide plate 17, the fixation of the slide plate 17 can be released. The rear outer wall of the block 5 is slidably connected to the front inner wall of the fixing plate 9. The rear outer wall of the block 5 is engaged with the front inner wall of the slide plate 17. One end of the spring 6 is fixedly connected to the front outer wall of the fixing plate 9, and the other end of the spring 6 is fixedly connected to the outer wall of the block 5.
[0034] Reference Figure 2 and Figure 3 The drying assembly includes a hot air blower 2, which is fixedly connected to the upper end of the barrel 1. A gas distribution block 11 is fixedly connected to the inner wall of the barrel 1. The gas distribution block 11 is connected to the hot air blower 2 through the upper pipe. Multiple nozzles are evenly distributed on the lower side of the gas distribution block 11.
[0035] Working principle: By fixing two pipes to the feeding connector 7 and feeding connector 8 respectively, the plastic granules to be dried are fed into the barrel 1 through the feeding pipe 4. Then, hot air generated by the hot air blower 2 is delivered into the barrel 1 through the nozzle under the air distribution block 11. The operation of the motor 3 drives the rotation of the rotating shaft 12, which agitates the plastic granules in the filter frame 10. The rotation of the auger 14 moves the plastic granules from the lower side to the upper side. The water generated during the drying process is discharged through the auger 14. After the material discharge connector 7 is discharged and the plastic granules are dried, the movable insert 5 is released from the fixation of the slide plate 17. The slide plate 17 is moved so that the material discharge connector 8 is aligned with the discharge hole on the lower side of the barrel 1. The fixed position of the insert 5 is released. Then the motor 16 is started. The operation of the motor 16 drives the rotating plate 15 to rotate. When the through groove on the rotating plate 15 coincides with the through groove on the filter frame 10, the plastic granules in the filter frame 10 are discharged from the filter frame 10 and discharged through the barrel 1 and the material discharge connector 8 to the next process.
