Description

Technical Field

[0001] This utility model relates to the field of conveying device technology, specifically to a conveying device for material drying. Background Technology

[0002] Currently, many materials, such as kitchen waste, have a high water content and therefore usually need to be dried.

[0003] Currently, the drying process for materials is usually carried out inside a drying chamber. For example, CN201920134998.2 discloses an automatic dust removal sludge dryer, which includes a chamber and a heat pump. The chamber has an air inlet chamber, a drying chamber, and an air outlet chamber arranged at intervals. Multiple sludge conveyor belts extending forward and backward are arranged at intervals in the drying chamber. Air outlets are distributed above each sludge conveyor belt. The sludge is transported downward layer by layer through the multi-layer sludge conveyor belts, which increases the conveying distance and residence time of the sludge in the drying chamber, thereby improving the drying efficiency.

[0004] However, in existing technologies, conveyor belt structures are simple. For example, the multiple sludge conveyor belts mentioned above are simply arranged vertically at intervals, and each sludge conveyor belt requires a corresponding drive unit, resulting in complex equipment and high energy consumption. Furthermore, multiple independent control systems are required, increasing operational difficulty and maintenance costs. Utility Model Content

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0022] Example 1, as Figure 1-5 As shown, a material drying conveying device includes a first conveyor belt 1, a second conveyor belt 2, and a third conveyor belt 3. The first conveyor belt 1, the second conveyor belt 2, and the third conveyor belt 3 are arranged sequentially from top to bottom in a housing 4. The output end of the first conveyor belt 1 corresponds to the input end of the second conveyor belt 2 through a first guide frame 5, and the output end of the second conveyor belt 2 corresponds to the input end of the third conveyor belt 3 through a second guide frame 6.

[0023] The first conveyor belt 1 includes a first conveyor frame 11 and a first belt body 12. First drive wheels 13 are rotatably connected to the left and right sides of the first conveyor frame 11 via bearings. The first belt body 12 is wound between the two first drive wheels 13. The front end of the central shaft of the first drive wheel 13 located on the left extends out of the first conveyor frame 11 and is coaxially fixedly mounted with a first gear 14. The second conveyor belt 2 includes a first conveyor frame 21 and a second belt body 22. Second drive wheels 23 are rotatably connected to the left and right sides of the second conveyor frame 21 via bearings. The second belt body 22 is wound between the two second drive wheels 23. The front end of the central shaft of the second drive wheel 23 located on the left extends out of the second conveyor frame 21 and is coaxially fixedly mounted with a second gear 24. The three conveyor belts 3 include a third conveyor frame 31 and a third belt body 32. The left and right sides of the third conveyor frame 31 are rotatably connected to third transmission wheels 33 via bearings. The third belt body 32 is wound around the two third transmission wheels 33. The front end of the central shaft of the third transmission wheel 33 on the left side passes through the third conveyor frame 31 and is coaxially fixedly mounted with a third gear 34 and a fourth gear 35. A drive motor 9 is installed inside the housing 4. The output shaft of the drive motor 9 is coaxially fixedly mounted with a drive gear 10. A first chain 7 is wound between the drive gear 10 and the fourth gear 35. A second chain 8 is wound between the third gear 34 and the first gear 14. The second gear 24 is located outside the second chain 8 and meshes with the second chain 8.

[0024] Working principle:

[0025] In operation, the drive motor 9 is started, causing the drive gear 10 to rotate counterclockwise. This, through the transmission of the first chain 7, drives the fourth gear 35 and the third transmission wheel 33 to rotate counterclockwise synchronously, causing the third belt 32 to rotate counterclockwise as well. The third gear 34, along with the third transmission wheel 33, is also driven counterclockwise by the second chain 8, causing the first gear 14 to rotate counterclockwise, which in turn drives the first belt 12 to rotate counterclockwise. Simultaneously, since the second gear 24 meshes with the outer side of the second chain 8, when the second chain 8 moves counterclockwise under the transmission of the third transmission wheel 33 and the first gear 14, it drives the second gear 24 to rotate clockwise, thus driving the second belt 22 to rotate clockwise. This causes the first conveyor belt 12, the second conveyor belt 22, and the third conveyor belt 32 to operate alternately in sequence, resulting in the first conveyor belt 1 and the second conveyor belt 2 having opposite conveying directions, and the second conveyor belt 2 and the third conveyor belt 3 having opposite conveying directions. Consequently, the first conveyor belt 1, the second conveyor belt 2, and the third conveyor belt 3 cooperate with each other to form a "Z"-shaped conveying path, ensuring that the material passes through the first conveyor belt 1, the second conveyor belt 2, and the third conveyor belt 3 in sequence during the conveying process. This greatly increases the conveying distance and residence time of the material during the conveying process, thereby effectively improving the drying treatment effect of the material.

[0026] In this embodiment, by arranging the first conveyor belt 1, the second conveyor belt 2, and the third conveyor belt 3 in parallel and spaced intervals within the housing 4, a multi-layer conveying structure is formed, thereby achieving multi-stage material conveying within a limited space, thus improving the space utilization and processing efficiency of the equipment. Furthermore, by rationally configuring the mutual cooperation of the first gear 14, the second gear 24, the third gear 34, and the fourth gear 35, as well as the winding method of the first chain 7 and the second chain 8, the drive motor 9 can be used to control the three conveyor belts (first conveyor belt 1, second conveyor belt 2, and third conveyor belt 3), greatly simplifying the mechanical structure and control requirements, and reducing the energy consumption and maintenance costs of the equipment.

[0027] In Example 2, as a further preferred embodiment of Example 1, a support beam 41 is fixedly installed inside the housing 4. The support beam 41 is located between the first gear 14 and the second gear 24. Rotating shafts are fixedly installed at both ends of the front side of the support beam 41. The outer surfaces of the two rotating shafts are respectively rotatably connected to the first tensioning gear 42 and the second tensioning gear 43 through bearings. The first tensioning gear 42 and the second tensioning gear 43 are both located inside the second chain 8, and both the first tensioning gear 42 and the second tensioning gear 43 mesh with the second chain 8.

[0028] By setting a first tensioning gear 42 and a second tensioning gear 43, the first tensioning gear 42 and the second tensioning gear 43 are respectively located inside the second chain 8 and apply an outward tension force to it, so as to keep the second chain 8 in a taut state, thereby effectively ensuring the transmission stability of the second chain 8. It also allows for a tighter meshing between the second chain 8 and the second gear 24, improving transmission efficiency and reducing chain wear.

[0029] In Example 3, as a further preferred embodiment of Example 1, the first guide frame 5 includes a first frame body 51. The upper end of the first frame body 51 is fixedly installed at the output end of the first conveyor frame 11. The lower end of the first frame body 51 is provided with a first guide slope 52, which corresponds to the input end of the second belt body 22. Multiple first partition plates 53 are uniformly and vertically fixedly connected to the upper surface of the first guide slope 52. Therefore, when the material is conveyed to the end along the first belt body 11, the first frame body 51 can effectively limit and guide the material, allowing it to smoothly slide into the input end of the second belt body 22 along the first guide slope 52. Furthermore, by vertically setting multiple first partition plates 53 on the first guide slope 52, the material can be effectively separated and dispersed, preventing material accumulation and ensuring that the material is evenly spread on the second belt body 22, thereby effectively improving the drying effect of the material.

[0030] In Example 3, as a further preferred embodiment of Example 1, the second guide frame 6 includes a second frame body 61. The upper end of the second frame body 61 is fixedly installed at the output end of the second conveyor frame 11. The lower end of the second frame body 61 is provided with a second guide slope 62, which corresponds to the input end of the third belt 32. Multiple second partition plates 63 are uniformly and vertically fixedly connected to the upper surface of the second guide slope 62. Therefore, when the material is conveyed to the end along the second belt 21, the second frame body 61 can effectively limit and guide the material, allowing it to smoothly slide along the second guide slope 62 into the input end of the third belt 32. Furthermore, by vertically setting multiple second partition plates 63 on the second guide slope 62, the material can be effectively separated and dispersed, preventing material accumulation and ensuring that the material is evenly distributed on the third belt 32, thereby effectively improving the drying effect of the material.

[0031] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
