[0034] Embodiment:

[0035] The embodiment of the present application discloses a preparation process of environmentally friendly polypropylene recycled plastic. Please refer to Figure 1 , Figure 2 and Figure 3, including a base 1. Above the middle of the base 1, there is a rotating cylinder 2. Outer cylindrical sleeves 3 are fixedly sleeved on the outer walls on both sides of the rotating cylinder 2.

And the plurality of flow holes 5 are all located between the two outer cylindrical sleeves 3 on both sides. A heating component is arranged on the outer side of the middle of the rotating cylinder 2. On one side of the outer wall of the right outer cylindrical sleeve 3, a first gear 6 is fixedly sleeved. A second gear 7 meshes with the bottom end of the first gear 6. One end face of the second gear 7 is connected by a rotating shaft to a driving motor 8. And the driving motor 8 is fixedly sleeved through the inner cavity at the lower end of the right support plate 4. The left end of the rotating cylinder 2 is fixedly connected to a fixing plate 9. And a feeding component is arranged on one side of the fixing plate 9. The right end of the rotating cylinder 2 is in sliding contact with a sealing plate 10. An auxiliary component is arranged in the inner cavity of the sealing plate 10. And three groups of locking components are distributed in a triangular form at the connection between the sealing plate 10 and the upper outer end of the right support plate 4;

[0036] The heating component includes an outer cylinder 11 located outside the rotating cylinder 2. Heating tubes 12 are fixedly installed on the inner wall of the outer cylinder 11 through a plurality of short rods. And the heating tubes 12 are sleeved on the outer side of the rotating cylinder 2. Two support rods 13 are fixedly connected to the outer wall at the bottom end of the outer cylinder 11. And the two support rods 13 are both fixedly installed on the top of the base 1. The settings of the outer cylinder 11 and the support rods 13 can not only realize the connection and fixation of the heating tubes 12, but also prevent the problem of scalding caused by accidental contact with the outer surface of the heating tubes 12 through the covering and isolating state of the heating tubes 12. There are multiple groups of heating components. And the multiple groups of heating components are linearly evenly and spacedly distributed on the outer side of the middle of the rotating cylinder 2.

[0037] The locking component includes a first ear block 14 fixedly connected to the outer wall of the sealing plate 10. On one side of the linear position of the first ear block 14, there is a second ear block 15. The second ear block 15 is fixedly installed on the outer wall of the right support plate 4. And a plug rod 16 is movably inserted through the inner cavity of the second ear block 15. The plug rod 16 is fixedly installed on one end face of the first ear block 14.

And a plurality of anti-slip grooves are evenly arranged on the outer wall circumference of the locking rotating wheel 17. The plurality of anti-slip grooves can facilitate the screwing operation of the locking rotating wheel 17.

[0038] Please refer to Figure 1 , Figure 4 , Figure 5 and Figure 6, the feeding assembly includes a circular hole 18 penetrating through the central position of the fixing plate 9. The central position of the fixing plate 9 is rotatably sleeved with an L-shaped pipe 19 through the circular hole 18. One end of the L-shaped pipe 19 away from the fixing plate 9 is fixedly connected with a feeding hopper 20. A square block 21 is fixedly sleeved on the outer wall of the L-shaped pipe 19 close to the fixing plate 9. A fixing rod 22 is fixedly connected to the bottom of the square block 21. The fixing rod 22 is a solid rod-shaped structure in an "L" shape, and the end of the fixing rod 22 away from the square block 21 is fixedly connected to the outer surface of the left support plate 4. With the arrangement of the square block 21 and the fixing rod 22, it plays a role of supporting and fixing the L-shaped pipe 19.

[0039] The auxiliary assembly includes a tube 23, which is fixedly sleeved through the central inner cavity position of the plugging plate 10. A fan group 24 is arranged in the middle position inside the tube 23. The auxiliary assembly also includes an enlarged hopper 25 fixedly connected to one end face of the tube 23. A baffle net plate 26 is fixedly connected to the end of the enlarged hopper 25 facing away from the tube 23. The enlarged hopper 25 and the baffle net plate 26 are both distributed inside one side of the rotating cylinder 2. A safety protection frame is arranged on the side of the fan group 24 facing away from the enlarged hopper 25, and the safety protection frame is fixedly installed on the inner wall of one side of the tube 23. The safety protection frame can realize the safety protection function on the outer end side position of the fan group 24, thus preventing the fan group 24 from causing accidental injury to the staff. The setting of the baffle net plate 26 at one end of the enlarged hopper 25 can prevent the problem of the regenerated plastic particles inside the rotating cylinder 2 from falling and accumulating into the enlarged hopper 25 during the rolling and flipping process while not hindering the fan group 24 from accelerating the gas flow. Furthermore, while ensuring the working safety factor of the fan group 24, it can improve the overall use safety and service life.

[0040] The implementation principle of the embodiment of this application is as follows: When in use, in the complete assembly state, the washed regenerated plastics are orderly placed into the inside of the feeding hopper 20 and roll into the inside of the rotating cylinder 2 under the action of the L-shaped pipe 19. Then, when the driving motor 8 makes the second gear 7 rotate, due to the meshing state of the second gear 7 and the first gear 6, the right outer sleeve 3 is indirectly driven to drive the rotating cylinder 2 to rotate. During this process, each side support plate 4 plays a role of rotational limit support for the outer sleeve 3. When the rotating cylinder 2 rotates passively, the regenerated plastic particles inside it perform rolling and flipping movements. Moreover, when the rotating cylinder 2 drives the fixing plate 9 to rotate synchronously, the fixing plate 9 uses the circular hole 18 to perform rotational cooperation with one end of the L-shaped pipe 19, and one end of the rotating cylinder 2 is in sliding contact and cooperation with the plugging plate 10;

[0041] While starting each heating tube 12 at the same time, the gas outside the rotating drum 2 can be heated, and the fan group 24 can be in a working state, so that the gas inside the rotating drum 2 can be diverted to the outside on one side. Thus, while the heated gas outside the rotating drum 2 enters its interior through a plurality of circulation holes 5, the recycled plastic particles are heat-dried and, under the action of the fan group 24, are discharged to the outside on one side of the rotating drum 2 via the baffle net plate 26, the enlarged hopper 25, and the tube 23, thereby realizing the rapid drying of the recycled plastic particles inside the rotating drum 2;

[0042] When the drying of the recycled plastic particles is completed, by screwing each locking runner 17, the plugging plate 10 and its upper structure can be detached from the outer wall of one side of each plug rod 16, and then the dried recycled plastic particles inside the rotating drum 2 can be extracted and collected conveniently.

[0043] The above are all the preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
