Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0031] Referring to Figures 1-2 The utility model provides an embodiment: a plastic particle drying device for waste plastic regeneration, including base 1, the top of base 1 is fixedly connected with fixed circular frame 2, the upper surface right side of fixed circular frame 2 is fixedly connected with air heater 3, and the plastic particle raw materials in the inside of fixed circular frame 2 can be heated and dried when air heater 3 starts, the upper surface of fixed circular frame 2 is fixedly connected with feeding pipe 4, and the raw materials can pass through feeding pipe 4 and enter the inside of fixed circular frame 2 to carry out drying treatment, the top of feeding pipe 4 is provided with sealing cover, can be inserted on the upper end of feeding pipe 4 to carry out sealing treatment, and the bottom surface of fixed circular frame 2 is provided with discharge port 5, and the raw materials in the inside of fixed circular frame 2 can be discharged through discharge port 5.

[0033] The upper surface of the rotating circular frame 6 is fixedly connected with a push plate 8, and the bottom surface of the rotating circular frame 6 is fixedly connected with a coarse filter screen 9. When the rotating circular frame 6 rotates, the push plate 8 and the coarse filter screen 9 rotate synchronously.
