Description

Technical Field

[0001] The utility model relates to the technical field of belt dehydrators, in particular to a high-pressure belt thickening and dehydrating machine. Background Technique

[0002] Sludge is an inevitable product after sewage treatment. If the sludge that has not been well treated and disposed enters the environment, it will directly cause secondary pollution to water bodies and the atmosphere, and will also pose a serious threat to the ecological environment and human activities. Therefore, sludge treatment is very cautious. As an environmental protection equipment, the function of a sludge dehydrator is to pressurize and dehydrate the high-moisture-content sludge generated in the sewage treatment process into a sludge cake with a high solid content, providing conditions for the subsequent disposal of sludge.

[0003] At present, when a large amount of sludge is dehydrated on the market, a belt dehydrator is used, and a spreading plate is installed above the filter belt to evenly spread the sludge on the filter belt, preparing for subsequent high-pressure dehydration treatment. However, the distance between the spreading plate and the filter belt of the current dehydrator with a spreading plate cannot be adjusted, which directly affects the dehydration effect on the filter belt. The inability to adjust may lead to uneven sludge dehydration, thereby reducing the dehydration efficiency. In view of this technical problem, this application proposes a high-pressure belt thickening and dehydrating machine. Content of the Utility Model

[0004] The purpose of the utility model is to solve the disadvantages existing in the prior art, and a high-pressure belt thickening and dehydrating machine is proposed. By rotating the rotating handle, the adjusting member drives the spreading plate to move on the threaded rod, thereby controlling the thickness of the sludge on the conveyor belt. When the upper filter cloth and the lower filter cloth dehydrate the sludge, when the filter cloth enters the inside of the cleaning box, the spray head inside the cleaning box will wash the surface of the filter cloth, thereby washing away the sludge attached to it and preventing pollution to the secondary dehydration.

[0005] To achieve the above object, the utility model provides the following technical solutions:

[0006] A high-pressure belt thickening and dewatering machine, comprising a main body. On the left and right sides of the top of the main body, adjusting shells are fixedly connected. Inside both of the adjusting shells, a spreading plate is connected through an adjusting component. On the front outer wall of the main body, there is a motor one. The driving end of the motor one is fixedly connected with a power shaft. On the outer periphery of the power shaft, there is a conveyor belt. The driving end of the motor one is fixedly connected with a pulley, and the pulley is located directly in front of the power shaft. On the inner wall of the main body, a drainage plate is fixedly connected. The upper left end of the drainage plate is located directly below the conveyor belt. On the right inner wall of the main body, a plurality of pressing rollers are rotatably connected. On the outer periphery of the plurality of pressing rollers, there is a lower filter cloth. Inside the lower filter cloth, there is a lower filter cloth guiding shaft. On the outer periphery of the plurality of pressing rollers, there is an upper filter cloth. Inside the upper filter cloth, there is an upper filter cloth guiding shaft. On the upper and lower inner walls of the main body, cleaning boxes are fixedly connected. Behind both of the cleaning boxes, a water storage tank is connected through a conveying component.

[0007] Further, the adjusting component includes threaded rods rotatably connected inside both of the adjusting shells. On the outer peripheries of both of the threaded rods, adjusting parts are threadedly connected. On the closer sides of the two adjusting parts, the left and right ends of the spreading plate are fixedly connected.

[0008] Further, the conveying component includes a water delivery pipe fixedly connected to the rear end of the cleaning box. The bottom end of the water delivery pipe is fixedly connected to the top of the water storage tank. A water pump is arranged on the outer periphery of the water delivery pipe.

[0009] Further, a plurality of spray heads are fixedly connected to the upper inner wall of the cleaning box.

[0010] Further, a drainage pipe is fixedly connected to the lower right side of the front end of the cleaning box. The right side of the drainage pipe is fixedly connected to a sewage pipe, and the bottom of the sewage pipe is fixedly connected to a sewage collection box.

[0011] Further, a rotary handle is arranged on the outer wall of the adjusting shell on the right side. The left side of the rotary handle is fixedly connected with a linkage shaft. On the outer periphery of the linkage shaft, two bevel gears two are fixedly connected. Below both of the bevel gears two, bevel gears one are meshed and connected. The bottoms of both of the bevel gears one are fixedly connected to the tops of the threaded rods.

[0012] Further, a drain pipe is fixedly connected to the lower right side of the front end of the main body.

[0013] Further, a motor two is arranged on the outer wall of the main body. The driving end of the motor two is connected to the front end of the pressing roller.

[0014] The utility model has the following beneficial effects:

[0015] 1. In the present utility model, a spreading plate is arranged above the conveyor belt, which can flatten the sludge on the conveyor belt and prevent the sludge from piling up. When the sludge enters the high-pressure dehydration area, it may cause uneven stress on the sludge between the upper filter cloth and the lower filter cloth by the pressure roller, resulting in incomplete sludge dehydration. By rotating the rotating handle, the adjusting member drives the spreading plate to move on the threaded rod, so as to adjust the distance between the spreading plate and the conveyor belt, and further control the thickness of the sludge on the conveyor belt.

[0016] 2. In the present utility model, after the upper filter cloth and the lower filter cloth dehydrate the sludge, there is still a small amount of sludge remaining on their surfaces. When the upper filter cloth and the lower filter cloth enter the inside of the cleaning box, the spray heads inside the cleaning box will wash the surfaces of the upper filter cloth and the lower filter cloth, so as to wash away the sludge attached to them, prevent pollution to the secondary dehydration, and the washed sewage will enter the sewage collection box through the drainage pipe, avoiding environmental pollution.

[0025] Referring to Figure 1 and Figure 2 FIGS. and, an embodiment provided by the present utility model: a high-pressure belt thickening and dewatering machine, including a main body 1. Both the left and right sides of the top of the main body 1 are fixedly connected with adjusting casings 12. Inside both of the two adjusting casings 12, a spreading plate 10 is connected through an adjusting member 21. On the front outer wall of the main body 1, there is a first motor 2. The driving end of the first motor 2 is fixedly connected with a power shaft 20. A conveyor belt 9 is arranged on the outer periphery of the power shaft 20. The driving end of the first motor 2 is fixedly connected with a pulley 3. The pulley 3 is located directly in front of the power shaft 20. The inner wall of the main body 1 is fixedly connected with a drainage plate 19. The upper left end of the drainage plate 19 is located directly below the conveyor belt 9.

The driving end of the second motor 4 is connected to the front end of the pressing roller 17. A drain pipe 5 is fixedly connected to the lower right side of the front end of the main body 1;

[0026] Specifically, start the first motor 2 to drive the connected power shaft 20 to rotate, so that the conveyor belt 9 on its outer wall drives the sludge placed on it to move, and moves it into the device for high-pressure dehydration. The sludge falls from the conveyor belt 9 onto the drainage plate 19 installed below its right side, and then onto the lower filter cloth 18. The sludge attached to the conveyor belt 9 will be scraped off by the scraper at the left end of the drainage plate 19, maintaining the cleanliness of the surface of the conveyor belt 9. Moreover, the pulley 3 on the transmission shaft of the first motor 2 drives the pulley 3 connected to the transmission roller of the upper filter cloth 8 through a belt to rotate. The sludge falling above the lower filter cloth 18 will first pass through the wedge-shaped area composed of the upper filter cloth 8 and the lower filter cloth 18 to remove the water on the surface of the sludge. Then, the pressure roller 17 performs high-pressure treatment on the sludge between the upper filter cloth 8 and the lower filter cloth 18. By starting the second motor 4 to drive the pressure roller 17 to rotate, and the pulley 3 connected to the transmission shaft of the second motor 4 drives the pulley 3 connected to the transmission roller of the lower filter cloth 18 through a belt to rotate. After continuously passing through multiple pressure rollers 17, most of the water inside the sludge can be removed. The sludge cake formed after dehydration will be discharged from the device for recycling, and the squeezed-out water can be recycled through the drain pipe 5 in front of the main body 1.

[0027] Refer to Figure 3 , wherein threaded rods 14 are rotatably connected inside both adjustment housings 12. Adjusting members 21 are threadedly connected to the outer circumferences of both threaded rods 14. The closer sides of both adjusting members 21 are fixedly connected to the left and right ends of the spreading plate 10. A rotary handle 13 is provided on the outer wall of the right adjustment housing 12. A linkage shaft 11 is fixedly connected to the left side of the rotary handle 13.

The bottoms of both bevel gears I 22 are fixedly connected to the tops of the threaded rods 14.

[0028] Specifically, rotate the rotary handle 13 to drive the connected linkage shaft 11 to rotate. The two bevel gears II 23 on the linkage shaft 11 will drive the meshed bevel gears I 22 below them and the threaded rods 14 below to rotate, so that the adjusting member 21 drives the spreading plate 10 to move up and down inside the adjustment housing 12, thereby adjusting the distance between the spreading plate 10 and the conveyor belt 9.

[0029] Refer to Figure 4 and Figure 5 , wherein a water delivery pipe 28 is fixedly connected to the rear end of the cleaning box 7. The bottom end of the water delivery pipe 28 is fixedly connected to the top of the water storage tank 25. A water pump 26 is provided on the outer circumference of the water delivery pipe 28. A plurality of spray nozzles 24 are fixedly connected to the upper inner wall of the cleaning box 7. A drainage pipe 29 is fixedly connected to the right front end of the cleaning box 7. A sewage pipe 27 is fixedly connected to the right side of the drainage pipe 29. The bottom of the sewage pipe 27 is fixedly connected to a sewage collection box 6.

[0030] Specifically, by starting the water pump 26, the clean water inside the water storage tank 25 enters the spray head 24 installed inside the cleaning box 7 through the water delivery pipe 28 to clean the filter cloth, maintaining the cleanliness of the filter cloth surface and avoiding contamination of the secondary dehydration.

[0031] Working principle: First, the sewage to be dehydrated is put on the left end of the conveyor belt 9 inside the main body 1. Then, according to the required thickness of the sludge, by rotating the rotating handle 13, the linked shaft 11 connected thereto rotates. The two bevel gears two 23 on the linked shaft 11 drive the meshing bevel gear one 22 below and the threaded rod 14 below to rotate, so that the adjusting member 21 drives the spreading plate 10 to move up and down inside the adjusting housing 12, thereby adjusting the distance between the spreading plate 10 and the conveyor belt 9. After adjusting the spreading plate 10, start the first motor 2 to drive the power shaft 20 connected thereto to rotate, so that the conveyor belt 9 on its outer wall drives the sludge placed thereon to move, moving it into the device for high-pressure dehydration. The sludge falls from the conveyor belt 9 onto the drainage plate 19 installed on its lower right side, and then onto the lower filter cloth 18. The sludge adhering to the conveyor belt 9 is scraped off by the scraper at the left end of the drainage plate 19, maintaining the cleanliness of the conveyor belt 9 surface. Moreover, the pulley 3 on the transmission shaft of the first motor 2 drives the pulley 3 connected to the transmission roller of the upper filter cloth 8 through a belt to rotate. The sludge falling above the lower filter cloth 18 will first pass through the wedge-shaped area composed of the upper filter cloth 8 and the lower filter cloth 18 to remove the water on the sludge surface, and then the pressure roller 17 performs high-pressure treatment on the sludge between the upper filter cloth 8 and the lower filter cloth 18. By starting the second motor 4 to drive the pressure roller 17 to rotate, and the pulley 3 connected to the transmission shaft of the second motor 4 drives the pulley 3 connected to the transmission roller of the lower filter cloth 18 through a belt to rotate. After continuously passing through multiple pressure rollers 17, most of the water inside the sludge can be removed. The formed mud cake after dehydration will be discharged from the device for recovery treatment. When the filter cloth passes through the cleaning box 7, by starting the water pump 26, the clean water inside the water storage tank 25 enters the spray head 24 installed inside the cleaning box 7 through the water delivery pipe 28 to clean the filter cloth, maintaining the cleanliness of the filter cloth surface and avoiding contamination of the secondary dehydration.
