Description

Technical Field

[0001] The utility model relates to the technical field of sludge dryers, and specifically, to a belt-type sludge dryer. Background Art

[0002] A sludge dryer is a device used to treat sludge and reduce its moisture content. Its working method is usually to evaporate the moisture in the sludge through heating, ventilation, etc., so as to achieve the drying of the sludge. A belt-type sludge dryer uses a conveyor belt to convey the sludge, and heats the sludge on the conveyor belt through a heater during the conveying process.

[0003] After retrieval, it is proposed in Chinese Patent Application No. CN202321715325.9 that a belt-type sludge dryer aims to solve the technical problem that the sludge distribution on the current conveyor belt is uneven, resulting in inconsistent drying degrees of the sludge. It includes a conveyor body, and a heating box body is arranged on the frame of the conveyor body. It also includes a spreading structure; the spreading structure is arranged on one side of the feeding end of the heating box body; the spreading structure includes a leveling strip A, a leveling strip B, and a leveling strip C; the leveling strip A, the leveling strip B, and the leveling strip C are arranged horizontally in sequence at the feeding port on one side of the heating box body; the leveling strip A and the leveling strip B, and the leveling strip B and the leveling strip C are respectively connected through a horizontal adjustment component; the leveling strip A is connected to one side of the heating box body through a vertical adjustment component. In the above prior art, by installing an adjustment component, the adjustment component is used to drive the spreading component to move, so that the spreading component levels the sludge, in order to improve the drying efficiency of the sludge.

[0004] The spreading component in the above prior art mainly uses a paving plate designed in a trapezoid shape to level the sludge on the conveyor belt. This method of leveling can effectively improve the uniformity of the sludge when heated, and at the same time increase the heating area, effectively improving the evaporation efficiency of the moisture. However, when the paving plate levels the sludge, it uses the paving plate to scrape the sludge flat. This method of leveling is likely to cause a certain extrusion of the sludge. After the sludge is leveled and forms a whole, the heating efficiency of the upper side is improved, but the evaporation efficiency of the moisture in the middle position of the sludge is slower, resulting in a reduction in the drying efficiency of the belt-type sludge dryer for the sludge. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a belt-type sludge dryer to solve the problem that the drying efficiency is relatively low when the belt-type sludge dryer in the prior art dries the sludge after leveling the sludge.

[0006] The present utility model provides the following technical solutions: A belt-type sludge dryer, comprising a bracket, a conveyor belt is rotatably connected inside the bracket, and a housing is fixedly connected to the upper side of the bracket. A heater is fixedly connected to the inner side of one end of the housing, and an adjusting assembly is fixedly connected to the end of the housing away from the heater. A leveling assembly is fixedly connected to the lower end of the adjusting assembly, and limiting assemblies are fixedly connected to the upper sides of both ends of the leveling assembly. Support assemblies are fixedly connected to both ends on one side of the leveling assembly, and a flipping assembly is fixedly connected to the end of the support assembly away from the leveling assembly.

[0007] As a preference of the above technical solution, the adjusting assembly includes a motor fixedly connected to the upper side of the end of the housing away from the heater, and a transmission rod is fixedly connected to the output shaft of the motor. A threaded cylinder is fixedly connected to the lower end of the transmission rod, and a threaded rod is engaged inside the lower end of the threaded cylinder.

[0008] As a preference of the above technical solution, the leveling assembly includes a fixing plate fixedly connected to the lower end of the threaded rod, and a leveling plate is fixedly connected to the lower end of the fixing plate. A dividing tooth is fixedly connected to the lower side of one end of the leveling plate.

[0009] As a preference of the above technical solution, the limiting assembly includes limiting plates rotatably connected to the upper sides of both ends of the fixing plate, and a slider is rotatably connected to the end of the limiting plate away from the fixing plate. A slide rail is sleeved outside the slider, and the upper end of the slide rail is fixedly connected to the housing.

[0010] As a preference of the above technical solution, the support assembly includes first connecting plates fixedly connected to both ends on the side of the leveling plate close to the heater, and a second connecting plate is fixedly connected to the inner side of the end of the first connecting plate away from the leveling plate.

[0011] As a preference of the above technical solution, the flipping assembly includes an insertion plate inserted inside the lower end of the second connecting plate, and a spring is fixedly connected to the upper end of the insertion plate. The spring is fixedly connected to the second connecting plate, and a flipping plate is fixedly connected to the lower end of the insertion plate.

[0012] Compared with the prior art, the beneficial effects of the present utility model are:

[0013] When the belt - type sludge dryer dries sludge, first start the heater and the conveyor belt, and then adjust the height of the paving component according to the thickness of the sludge to be paved. When adjusting, start the adjusting component. With the assistance of the limiting component, the adjusting component drives the paving component to move. After the paving component moves, the supporting component synchronously drives the flipping component to move. When the paving component moves to the appropriate position, then turn off the adjusting component. Subsequently, place the sludge on the conveyor belt for transportation. When the sludge is transported to the paving component, the paving component levels the sludge. Then use the heater to heat the leveled sludge. When the heated sludge moves to the flipping component, the flipping component flips the sludge for the heating component to heat the flipped sludge again, so that when the belt - type sludge dryer processes the sludge, it can effectively level the sludge before flipping, thereby increasing the heating area and uniformity of the sludge, and thus improving the evaporation efficiency of the moisture in the sludge.

Detailed Implementation Modes

[0021] 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.

[0022] Such as Figures 1-6As shown in the figure, the utility model provides a technical solution: a belt type sludge dryer, which includes a bracket 1. Inside the bracket 1, a conveyor belt 11 is rotatably connected. And on the upper side of the bracket 1, a housing 12 is fixedly connected. Inside one end of the housing 12, a heater 13 is fixedly connected. And at one end of the housing 12 away from the heater 13, an adjustment component is fixedly connected. At the lower end of the adjustment component, a leveling component is fixedly connected. And on the upper sides at both ends of the leveling component, a limiting component is fixedly connected. At both ends on one side of the leveling component, a supporting component is fixedly connected. And at one end of the supporting component away from the leveling component, a turning component is fixedly connected. When drying the sludge, first start the heater 13 and the conveyor belt 11. Then adjust the height of the leveling component according to the thickness of the sludge that needs to be leveled. When adjusting, start the adjustment component. The adjustment component drives the leveling component to move with the assistance of the limiting component. After the leveling component moves, it synchronously drives the turning component to move through the supporting component. When the leveling component moves to a suitable position, then turn off the adjustment component. Subsequently, place the sludge on the conveyor belt 11 for transportation. When the sludge is transported to the leveling component, the sludge is leveled by the leveling component. Subsequently, use the heater 13 to heat the leveled sludge. When the heated sludge moves to the turning component, then turn the sludge over through the turning component, so that the heating component can heat the turned-over sludge again. When the belt type sludge dryer processes the sludge, it can effectively level the sludge and then turn it over, thereby increasing the heating area and uniformity of the sludge, and thus improving the evaporation efficiency of the moisture in the sludge.

[0023] As Figure 2 and Figure 4 shown in the figure, the adjustment component includes a motor 2 fixedly connected to the upper side of one end of the housing 12 away from the heater 13. And the output shaft of the motor 2 is fixedly connected with a transmission rod 21. At the lower end of the transmission rod 21, a threaded cylinder 22 is fixedly connected. And inside the lower end of the threaded cylinder 22, a threaded rod 23 is meshed. Start the motor 2. After the motor 2 starts, the output shaft drives the transmission rod 21 and the threaded cylinder 22 to rotate. After the threaded cylinder 22 rotates, through the meshing with the threaded rod 23, the threaded rod 23 is pushed to move the leveling component, which is convenient for adjusting the position of the leveling component.

[0024] As Figure 4 shown in the figure, the leveling component includes a fixing plate 3 fixedly connected to the lower end of the threaded rod 23. And at the lower end of the fixing plate 3, a leveling plate 31 is fixedly connected. At the lower side of one end of the leveling plate 31, a dividing tooth 32 is fixedly connected. The leveling plate 31 is used to level the sludge, and at the same time, the dividing tooth 32 is used to divide the leveled sludge, so as to increase the heating area subsequently.

[0025] As Figure 4 and Figure 5As shown in the figure, the limiting component includes a limiting plate 4 rotatably connected to the upper sides of both ends of the fixing plate 3, and a slider 41 is rotatably connected to the end of the limiting plate 4 away from the fixing plate 3. A slide rail 42 is sleeved outside the slider 41, and the upper end of the slide rail 42 is fixedly connected to the housing 12. The movement of the paving plate 31 drives the limiting plate 4 to push the slider 41 to slide in the slide rail 42, thereby restricting the movement of the fixing plate 3 and the threaded rod 23.

[0026] As Figure 5 shown in the figure, the supporting component includes first connecting plates 5 fixedly connected to both ends of one side of the paving plate 31 close to the heater 13, and a second connecting plate 51 is fixedly connected to the inner side of the end of the first connecting plate 5 away from the paving plate 31. The first connecting plate 5 and the second connecting plate 51 facilitate the support of the flipping component.

[0027] As Figure 4 and Figure 6 shown in the figure, the flipping component includes a plug board 6 inserted into the lower end inside the second connecting plate 51, and a spring 61 is fixedly connected to the upper end of the plug board 6. The upper end of the spring 61 is fixedly connected to the second connecting plate 51, and a flipping plate 62 is fixedly connected to the lower end of the plug board 6. The sludge is flipped by the provided flipping plate 62 so that the heater 13 can heat the other side of the sludge.

[0028] Working principle: When drying sludge, first start the conveyor belt 11 and the heater 13, and then adjust the positions of the paving plate 31 and the dividing teeth 32 according to the height at which the sludge needs to be paved. When adjusting, start the motor 2. After the motor 2 starts, the output shaft drives the transmission rod 21 and the threaded barrel 22 to rotate. After the threaded barrel 22 rotates, through the engagement with the threaded rod 23, the threaded rod 23 is pushed to move the fixed plate 3. The movement of the fixed plate 3 drives the limiting plate 4, the paving plate 31 and the dividing teeth 32 to move. When the limiting plate 4 moves, it drives the slider 41 to slide in the slide rail 42, so as to limit the movement of the threaded rod 23 and the fixed plate 3 by the sliding of the slider 41 in the slide rail 42. The movement of the paving plate 31 synchronously drives the first connecting plate 5 and the second connecting plate 51 to move. The movement of the second connecting plate 51 synchronously drives the plug plate 6 and the turning plate 62 to move. When the lower side of the turning plate 62 is in contact with the conveyor belt 11 after moving, at this time, the second connecting plate 51 continues to press down, and after the second connecting plate 51 moves down, it compresses the spring 61 under the support of the plug plate 6 and the turning plate 62. When the paving plate 31 and the dividing teeth 32 move to the appropriate positions, at this time, turn off the motor 2, and then place the sludge on the conveyor belt 11. The conveyor belt 11 conveys the sludge. When the sludge is conveyed to the paving plate 31, the paving plate 31 levels the sludge, and at the same time, the dividing teeth 32 divide the leveled sludge, so as to form a certain distance between the sludge. Then, the heater 13 heats the divided sludge. When the divided sludge is heated and moves to the turning plate 62, at this time, the turning plate 62 turns the divided sludge, so as to facilitate the heater 13 to heat the other side of the sludge in the subsequent process.

[0029] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
