[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Refer to Figure 1-6 , a disk dryer with an automatic cleaning mechanism, including a dryer housing 1, a dryer top cover 2 is arranged at the top of the dryer housing 1, a blanking pipe 3 is arranged at one end inside the dryer housing 1, vertical support columns 8 are fixed at both ends of the bottom of the dryer top cover 2, a plurality of circular heating plates 7 are arranged between the two vertical support columns 8, a driving motor 4 is bolted to the bottom of the dryer housing 1, an output end of the driving motor 4 is fixed with a vertical rotating column 5, and a material pushing plate 6 is arranged on the outer side of the vertical rotating column 5 and on the top of the circular heating plate 7;

[0025] A vertical mounting column 12 is arranged at one end inside the dryer housing 1, a plurality of liquid spray heads 13 are rotatably connected inside the vertical mounting column 12 through a pin shaft, and a rotating mechanism for rotating the liquid spray heads 13 is arranged inside the vertical mounting column 12;

[0026] A liquid injection assembly for injecting liquid inside the liquid spray heads 13 is arranged inside the dryer housing 1;

[0027] The rotating mechanism includes a hydraulic cylinder 16. The hydraulic cylinder 16 is located inside the vertical mounting column 12 and fixedly connected to the vertical mounting column 12. A vertical lifting block 17 is fixed to the output end of the hydraulic cylinder 16. On both sides inside the vertical lifting block 17, there are obliquely rotating columns 18 rotatably connected through pin shafts. The top of the obliquely rotating column 18 is rotatably connected to the liquid spray head 13 through a pin shaft.

[0028] Inside the vertical mounting column 12, there is a vertical sliding groove adapted to the vertical lifting block 17. The vertical lifting block 17 is located inside the vertical sliding groove and slidably connected to the vertical mounting column 12 through the vertical sliding groove. Through the setting of the vertical sliding groove, the vertical lifting block 17 can perform vertical sliding inside the vertical mounting column 12. Furthermore, the movement trajectory of the vertical lifting block 17 can be guided, making the movement of the vertical lifting block 17 more stable. Through the movement of the vertical lifting block 17 via the obliquely rotating column 18, the liquid spray head 13 can rotate inside the vertical mounting column 12.

[0029] Here, the operation of the hydraulic cylinder 16 enables the vertical lifting block 17 to perform vertical lifting inside the vertical mounting column 12. The lifting of the vertical lifting block 17 enables the liquid spray head 13 to rotate inside the vertical mounting column 12 through the obliquely rotating column 18.

[0030] The liquid injection assembly includes an annular liquid tank 9. The annular liquid tank 9 is fixed inside the dryer housing 1. A rotary annular plate 10 is rotatably connected to the top of the annular liquid tank 9. The bottom of the vertical mounting column 12 is fixedly connected to the rotary annular plate 10. A vertical liquid pipe 11 is provided on the top of the rotary annular plate 10. One end of the annular liquid tank 9 is provided with a horizontal liquid injection pipe 14, and the horizontal liquid injection pipe 14 penetrates inside the dryer housing 1.

[0031] The vertical liquid pipe 11 and the liquid spray head 13 are connected by a connecting hose 15. Through the setting of the connecting hose 15, the liquid inside the vertical liquid pipe 11 is injected into the liquid spray head 13 through the connecting hose 15, enabling the liquid inside the liquid spray head 13 to be replenished.

[0032] A circular ring is fixed to the outside of the rotary annular plate 10. A circular groove is provided inside the annular liquid tank 9. The rotary annular plate 10 and the annular liquid tank 9 are rotatably connected through the circular ring and the circular groove, enabling the rotary annular plate 10 to rotate inside the annular liquid tank 9. Furthermore, it can prevent the liquid inside the annular liquid tank 9 from leaking, and enable the rotary annular plate 10 to rotate inside the annular liquid tank 9.

[0033] A liquid spray head 13 is also sleeved outside the vertical rotating column 5. One end of the liquid spray head 13 close to the vertical mounting column 12 is fixedly connected to the vertical mounting column 12. Through the operation of the driving motor 4, the vertical rotating column 5 can rotate. The rotation of the vertical rotating column 5 is transmitted through the liquid spray head 13 and the vertical mounting column 12, enabling the annular rotating plate 10 to rotate inside the annular liquid tank 9. Furthermore, the vertical mounting column 12 can rotate with the vertical rotating column 5 as the center, allowing the liquid spray head 13 to spray the surface of the circular heating plate 7, thereby cleaning the surface of the circular heating plate 7;

[0034] Herein, through an external pump, liquid can be injected into the interior of the horizontal liquid injection pipe 14, and through the horizontal liquid injection pipe 14, it is injected into the interior of the annular liquid tank 9. With the arrangement of the vertical liquid pipe 11 and the connecting hose 15, the liquid can be injected into the interior of the liquid spray head 13 and sprayed onto the surface of the circular heating plate 7 by the liquid spray head 13;

[0035] Working principle: Through an external pump, liquid can be injected into the interior of the horizontal liquid injection pipe 14, and through the horizontal liquid injection pipe 14, it is injected into the interior of the annular liquid tank 9. With the arrangement of the vertical liquid pipe 11 and the connecting hose 15, the liquid can be injected into the interior of the liquid spray head 13 and sprayed onto the surface of the circular heating plate 7 by the liquid spray head 13;

[0036] The operation of the hydraulic cylinder 16 enables the vertical lifting block 17 to perform vertical lifting inside the vertical mounting column 12. The lifting of the vertical lifting block 17 causes the liquid spray head 13 to rotate inside the vertical mounting column 12 through the inclined rotating column 18, thereby enabling the spraying angle of the liquid spray head 13 to be adjusted to increase the cleaning range. Through the operation of the driving motor 4, the vertical rotating column 5 can rotate. The rotation of the vertical rotating column 5 is transmitted through the liquid spray head 13 and the vertical mounting column 12, enabling the annular rotating plate 10 to rotate inside the annular liquid tank 9, allowing the liquid spray head 13 to rotate with the vertical rotating column 5 as the center, and further enabling the liquid spray head 13 to better clean the surface of the circular heating plate 7.

[0037] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
