[0027] The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0028] Embodiment 1

[0029] As Figures 1-5As shown in the figure, an embodiment of the present utility model provides a drying device for PVC plastic particles, which includes a drying frame body 1. An electric conveyor belt 2 is installed at the inner end of the drying frame body 1. A mixing area 13 is arranged at the upper end of the electric conveyor belt 2. The mixing area 13 includes a pair of top cross bars 4. At the left and right sides of the mutually approaching ends of the two top cross bars 4, connecting cross plates 6 are fixedly connected. In the middle of the lower end of the connecting cross plate 6, a downwardly convex outer rod 7 is fixedly connected. On the left side of the downwardly convex outer rod 7 at the right end, a motor driver 8 is fixedly connected. The output end of the motor driver 8 is fixedly connected with a rotatable horizontal shaft 9. At the outer end of the rotatable horizontal shaft 9, a pair of turning arc-shaped pieces 10 are fixedly connected.

[0030] The rotatable horizontal shaft 9 is installed between the two downwardly convex outer rods 7. The two turning arc-shaped pieces 10 are symmetrically arranged. The two top cross bars 4 are located at the front and rear sides of the mixing area 13. The mixing area 13 is located in the middle of the upper end of the electric conveyor belt 2. A number of plastic particle bodies to be processed 12 are laid on the upper end of the electric conveyor belt 2. The plastic particle bodies to be processed 12 cooperate with the turning arc-shaped pieces 10. At the lower end of the top cross bar 4, an electric rotating shaft 11 is fixedly connected.

[0031] Embodiment 2

[0032] In one embodiment, the output end of the electric rotating shaft 11 is fixedly connected with a material scraping cross plate 5. The material scraping cross plate 5 is located directly above the electric conveyor belt 2. The material scraping cross plate 5 cooperates with the plastic particle bodies to be processed 12.

[0033] Side baffle plates 3 are symmetrically and fixedly connected to the left and right inner walls of the drying frame body 1.

The electric conveyor belt 2 is externally connected with a motor, and the drying frame body 1 is externally connected with a drying pump.

[0034] When the utility model is in operation: In this solution, a number of plastic particle bodies 12 to be processed are laid flat above the electric conveyor belt 2. The electric conveyor belt 2 is used to uniformly convey the plastic particle bodies 12 to be processed in the drying frame body 1 at a constant speed, so that the plastic particle bodies 12 to be processed are in uniform contact with hot air, enabling the plastic particle bodies 12 to be processed to be uniformly dried. During the drying process, although the plastic particle bodies 12 to be processed are laid flat in a thin layer on the electric conveyor belt 2, the lower wall surface of the plastic particle bodies 12 to be processed is always in contact with the upper wall surface of the electric conveyor belt 2. This state leads to room for improvement in the drying efficiency of the plastic particle bodies 12 to be processed. Therefore, a mixing area 13 is arranged at the middle position of the upper end of the electric conveyor belt 2. The mixing area 13 can drive the rotatable horizontal shaft 9 to rotate by itself through the motor driver 8, so that the turning arc-shaped pieces 10 on both sides of the rotatable horizontal shaft 9 are turned over and come into contact with the plastic particle bodies 12 to be processed, shoveling up and then dropping some of the plastic particle bodies 12 to be processed again, causing the contact surface between the plastic particle bodies 12 to be processed and the electric conveyor belt 2 to be turned over, thereby improving the drying efficiency of the plastic particle bodies 12 to be processed, facilitating the uniform and comprehensive contact between the outer wall surfaces of the plastic particle bodies 12 to be processed and the hot air in the drying frame body 1. And scraping plates 5 can be arranged on both the front and rear sides of the mixing area 13. The scraping plates 5 facilitate keeping the plastic particle bodies 12 to be processed in a flat state before and after stirring, which is conducive to ensuring the neatness of the plastic particle bodies 12 to be processed during the drying state. At the same time, during the process of the scraping plates 5 scraping the materials, the scraping plates 5 can be driven to rotate and turn over by the electric rotating shaft 11. The scraping plates 5 can control the interval between the scraping plates 5 and the electric conveyor belt 2 through this turning force, and thus the laying thickness of the plastic particle bodies 12 to be processed can be flexibly adjusted, making the use process of the scraping plates 5 more flexible.
