[0031] Reference Figure 1-Figure 4 According to an embodiment of the utility model, a dual-mode plastic particle drying device includes a bracket 11, a drying barrel 12 is arranged in the bracket 11, the drying barrel 12 is rotatably connected to the bracket 11, a storage chamber 13 with an opening upward is arranged in the drying barrel 12, and a cover plate 18 for closing the storage chamber 13 is rotatably connected in the drying barrel 12, and the cover plate 18 is fixed in the bracket 11, that is, the drying barrel 12 can rotate relative to the bracket 11 and the cover plate 18, and a plurality of drainage holes 21 are arranged in the curved surface of the storage chamber 13, and the plastic particles located in the drying barrel 12 will be spun off during the rotation of the drying barrel 12, and the outflowing water will be discharged through the drainage holes 21.

[0032] In addition, a rotating shaft 16 is rotatably connected in the cover plate 18, and the rotating shaft 16 extends into the storage chamber 13, and a plurality of stirring rods 17 equidistantly distributed up and down are arranged on the outer shell of the rotating shaft 16. An air inlet and an air outlet are arranged in the cover plate 18, and a blower 19 connected to the air inlet is arranged on the cover plate 18. When the drying barrel 12 is in a fixed state, the rotating shaft 16 rotates and the blower 19 is energized, the stirring rod 17 stirs the plastic particles in the drying barrel 12, and the blower 19 generates airflow and dries the plastic particles in the drying barrel 12. In order to further improve the drying effect, an electric heating wire is arranged in the air inlet so that the air entering the storage chamber 13 is hot air, thereby constituting a drying function.

[0033] The dual-mode plastic particle drying equipment also includes a driving assembly, which is used to drive the drying barrel 12 and the rotating shaft 16 to rotate independently. A feed port is provided in the cover plate 18, and a discharge port is provided in the lower side of the storage cavity 13, and a valve is provided in the discharge port.

[0034] In this embodiment, the driving assembly includes a spin-drying motor 14 disposed in the bracket 11, and a first output shaft extending from the spin-drying motor 14 is connected to the bottom surface of the drying barrel 12;

[0035] A stirring motor 15 is also provided on the bracket 11. A No. 2 output shaft extending from the stirring motor 15 is connected to the rotating shaft 16 through a connecting mechanism, so that the No. 2 output shaft can drive the rotating shaft 16 to rotate. The connecting mechanism is a clutch 20. The clutch 20 connects the No. 2 output shaft and the rotating shaft 16. In the present embodiment, the clutch 20 is a pneumatic clutch.

[0036] Specific plastic granule drying process:

[0037] First, the staff puts the plastic particles into the storage chamber 13, and then controls the spin motor 14 to be energized, and controls the No. 2 output shaft and the rotating shaft 16 to be disconnected through the clutch 20. At this time, the drying barrel 12 rotates and drives the plastic particles located therein to be spun. During this process, the plastic particles will drive the rotating shaft 16 to rotate. Since the clutch 20 is in a disconnected state, the rotating rotating shaft 16 will not interfere with the No. 2 output shaft, and water will be thrown out through the drainage hole 21 during the spinning process.

[0038] After a certain period of time, the spin drying operation is completed, the spin drying motor 14 controls the drying barrel 12 to remain stationary, and then the clutch 20 connects the second output shaft and the rotating shaft 16, and the stirring motor 15, the blower 19 and the heating wire are energized. At this time, the rotating shaft 16 drives the stirring rod 17 to stir the plastic particles in the storage chamber 13 and perform the drying operation.

[0039] In the second embodiment of the dual-mode plastic particle drying device, in order to improve the drying efficiency and avoid excessive cooling in the storage chamber 13, the drying barrel 12 is rotatably connected to the outside with a ring 25, and a connecting hole 22 adapted to the position of the drainage hole 21 is provided in the ring 25, and the connecting hole 22 can be misaligned with the drainage hole 21, and the ring 25 can maintain a relative angle relationship with the drying barrel 12 through a locking component;

[0040] In the above-mentioned drying process of the plastic particles, when the drainage hole 21 is directly opposite to the connecting hole 22, the drainage hole 21 can drain water, and in the subsequent drying process of the plastic particles, the ring 25 needs to be rotated by a certain angle so that the drainage hole 21 and the connecting hole 22 are misaligned to close the drainage hole 21 and avoid excessively rapid cooling in the storage chamber 13.

[0041] In this embodiment, the locking assembly includes two latch holes provided in the outer curved surface of the drying barrel 12, and the inner thread of the ring 25 is connected with a threaded shaft 23 which can be inserted into the latch holes. The two latch holes and the threaded shaft 23 are at the same height level. When the threaded shaft 23 is screwed into one of the latch holes, the drainage hole 21 is opposite to the through hole 22, and when the threaded shaft 23 is screwed into the other latch hole, the drainage hole 21 is misaligned with the connecting hole 22, and the ring 25 closes the connecting hole 22.

[0042] In the third embodiment of the dual-mode plastic particle drying equipment, in order to further improve the drying efficiency, an air duct 24 is connected to the side of the storage chamber 13 through a connecting frame. The air duct 24 is vertically arranged and can face the air inlet. The independent design of the air duct 24 and the cover plate 18 prevents the plastic particles from hitting the air duct 24 during the drying process. After the drying barrel 12 stops rotating, the air duct 24 can face the air inlet so that the wind blown in by the blower 19 can further contact the plastic particles at the bottom of the storage chamber 13.

[0043] In addition, in order to avoid interference between the stirring rod 17 and the air duct 24 when the rotating shaft 16 rotates, only the end of the stirring rod 17 located at the bottom is attached to the curved surface of the storage chamber 13, and the air duct 24 is higher than the stirring rod 17 located at the bottom. The other stirring rods 17 are shorter and will not collide with the air duct 24 during rotation.

[0044] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by any technician in the field of the present invention are included in the patent scope of the present invention.
