Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see the appendix Figure 1 - Appendix Figure 3This utility model provides an embodiment of a drum drying device with a dispersing shaft, comprising a base plate 1, with supports 4 fixedly connected to both the left and right sides of the base plate 1, and protective plates 7 fixedly connected to the top of each support 4. A drying drum 9 is fixedly connected to the inner center of the protective plate 7, and multiple inclined plates 18 are fixedly connected to the inner side of the drying drum 9. A middle cylinder 23 is fixedly connected to the outer wall of the multiple inclined plates 18, and an inner cylinder 24 is fixedly connected to the inner side of the middle cylinder 23. Inclined plates 26 are fixedly connected to the inner side of the inner cylinder 24. A support 25 is fixedly connected to the left end of the left support 4, and the top of the support 25 is fixedly connected to... A dispersing motor 6 is connected to the output end of the dispersing motor 6, and a pulley 15 is fixedly connected to the output end of the dispersing motor 6. The outer walls of the two pulleys 15 are connected through the inner side of the transmission belt 14. A dispersing shaft 17 is fixedly connected to the inner middle of the upper pulley 15. A chain 20 is fixedly connected to the outer wall of the dispersing shaft 17. A cutting blade 19 is fixedly connected to the middle of the outer wall of the dispersing shaft 17. A pusher plate 27 is fixedly connected to the middle of the outer wall of the dispersing shaft 17 near the edge. A drive assembly is provided on the top of the bottom plate 1. A feed 11 is connected to the top right side of the outer wall of the drying drum 9. A heat source inlet 25 is opened at the bottom right side of the drying drum 9.

[0031] Specifically, the frame is supported by bracket 4, and a protective plate 7 is fixedly connected to it. Multiple inclined plates 18 are evenly fixedly connected to the inner side of the drying drum 9. These inclined plates 18 are fixed to the inner wall of the drum. When the drying drum 9 starts to rotate, the inclined plates 18 can drive the material entering the drum to tumble and stir, thereby improving the drying efficiency and providing stable support for components such as the dispersing motor 6. The top of the bracket 5 is fixedly connected to the dispersing motor 6, which serves as the dispersing power source. Chains 20 are evenly fixedly connected to the outer wall of the dispersing shaft 17. The chains 20 are made of metal and have a certain degree of flexibility and wear resistance. When the dispersing shaft 17 rotates at high speed, the chains 20 swing at high speed, making strong impacts and dispersing, so that the clumped material is quickly dispersed into smaller particles.

[0032] Please see the appendix Figure 3 - Appendix Figure 5 The drive assembly includes a drive motor reducer 13. The bottom of the drive motor reducer 13 is fixedly connected to the top right side of the base plate 1. A drive pinion 12 is fixedly connected to the output end of the drive motor reducer 13. A drive gear 10 is meshed with the outer wall of the drive pinion 12. A support plate 3 is fixedly connected to the top left and right sides of the base plate 1. A support roller 2 is fixedly connected to the top front and rear sides of the support plate 3. A support running belt 8 is fixedly connected to the left and right sides of the outer wall of the drying drum 9. The outer wall of the support running belt 8 is slidably connected to the outer side of the support roller 2. The inner side of the drive gear 10 is fixedly connected to the right side of the outer wall of the drying drum 9.

[0033] Specifically, the drive motor reducer 13 serves as the power source. The bottom of the drive motor reducer 13 is firmly connected to the top right side of the base plate 1 via high-strength bolts, providing good rigidity and stability. This ensures the stability and balance of the drying drum 9 during rotation. Support plates 3 are fixedly connected to the left and right sides of the top of the base plate 1, ensuring the smooth rotation of the support rollers 2. During the rotation of the drying drum 9, the support belt 8 rotates along with the drying drum 9 and slides relative to the support rollers 2. Supported by the support plates 3, the support rollers 2 provide stable support for the drying drum 9, ensuring the drying drum 9 maintains balance and stability during rotation.

[0034] Please see the appendix Figure 5 - Appendix Figure 7 The bottom inner side of the support frame 4 is fixedly connected to the inclined frame 22, and the top middle of the support frame 4 is fixedly connected to the bearing support 21. The middle inner side of the bearing support 21 is rotatably connected to the outer wall of the dispersing shaft 17. The bottom left side of the outer wall of the drying drum 9 is connected to the discharge 16.

[0035] Specifically, due to the strength and stability of the support frame 4, inclined frames 22 are fixedly connected to its inner bottom. To ensure that the dispersing shaft 17 can be stable, a bearing support 21 is fixedly connected to the top center of the support frame 4. The discharge 16 is located at the bottom left side of the outer wall of the drying drum 9, so that it can be smoothly discharged after drying. When the drying drum 9 is driven to rotate, the material is continuously tumbling and stirring inside the drum, gradually moving towards the bottom of the drum. The discharge 16 is set at the bottom position, so that the dried material flows naturally to the discharge 16, reducing the material residue in the drum and improving the discharge efficiency of the discharge 16.

[0036] Working principle: Material enters the drying drum 9 from the feed end 11, and then travels through an S-shaped reversal route via the cooperation of the inner drum 24 and the middle drum 23. At this point, the material to be dried is lifted and dropped by the evenly distributed inclined plates 26 on the inner drum 24 wall, allowing for sufficient heat exchange and thus achieving the purpose of drying the material. The inner drum 24 is equipped with a dispersing shaft 17, which is equipped with a separate dispersing motor 6. The two ends of the dispersing shaft 17 are supported by bearings 21. With the cooperation of the chain 20, cutting blades 19 and pusher plate 27 distributed on the dispersing shaft 17, the lumps of the material to be dried can be thoroughly broken up during the drying process, improving drying efficiency. The number of dispersing shafts 17 can be determined according to the characteristics of the material. Therefore, it can effectively and thoroughly dry the material, improve drying efficiency, and meet daily use needs.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
