Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically an underwater self-cleaning sludge scraping device. Background Technology

[0002] Wastewater treatment is an important part of environmental protection and sustainable resource utilization. Its core objective is to remove harmful substances from wastewater through physical, chemical and biological means so that it meets discharge standards or can be reused.

[0003] Wastewater treatment can be broadly divided into physical treatment and chemical treatment. Physical treatment mainly uses screens and grids to remove large suspended solids, then uses gravity or air bubbles to separate suspended solids and grease, and finally uses sand filters or membrane filtration technology to further remove fine particles.

[0004] Currently, existing technologies mainly remove suspended matter through bar screens and sieves, which requires water flow. This results in a longer time required to separate suspended matter, leading to a longer overall treatment cycle. In addition, some suspended matter inevitably adheres to the bar screens and sieves, resulting in insufficient removal and an overall treatment efficiency that needs to be improved.

[0005] Therefore, an underwater self-cleaning mud scraping device is proposed to address the above problems. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Specific implementation examples are given below.

[0026] Please see Figures 1-5 This utility model provides an underwater self-cleaning mud scraping device, including a cleaning tank 1 and a mud scraping assembly; the mud scraping assembly includes an electric telescopic rod 2, which is inclined and has wedge-shaped platforms 3 fixedly connected to both ends. One side of one of the wedge-shaped platforms 3 is fixedly connected to the inner wall of the cleaning tank 1. The end of the electric telescopic rod 2 away from the cleaning tank 1 is fixedly connected to a movable clamping plate 4 via the wedge-shaped platform 3. An arc-shaped clamping sleeve 5 is rotatably connected to the bottom of the movable clamping plate 4, and a rotating scraper 6 is clamped to the inner wall of the arc-shaped clamping sleeve 5. The two sides of the cleaning tank 1 are rotatably connected to the inner wall of the cleaning tank 1, and movable wheels 7 are fixedly connected to the bottom of the cleaning tank 1. During operation, the mud scraping assembly is set to... The cleaning tank 1 is placed inside the cleaning tank 1. The moving wheels 7 drive the cleaning tank 1 to move in the water. Two wedge-shaped platforms 3 are set at both ends of the electric telescopic rod 2, so that the electric telescopic rod 2 can be tilted and supported. After the electric telescopic rod 2 is working, it extends and retracts, thereby driving the moving plate 4 to move back and forth. After the moving plate 4 moves, it drives the arc-shaped sleeve 5 to move, and then drives the rotating scraper 6 to rotate inside the cleaning tank 1, thereby scraping the mud. By setting up the mud scraping assembly, the cleaning tank 1 can be placed in the water and moved. When working, the rotating scraper 6 can scrape the mud in the water, which can quickly process the mud in the water and improve the overall work efficiency.

[0027] Furthermore, such as Figure 2 and Figure 5As shown, the number of arc-shaped retaining sleeves 5 and rotating scrapers 6 is multiple, and the multiple arc-shaped retaining sleeves 5 and rotating scrapers 6 are evenly and equidistantly arranged at the bottom of the moving retaining plate 4. A suction baffle 8 is fixedly connected to the top of the cleaning tank 1, and a motor cylinder 9 is fixedly connected to the top of the suction baffle 8. The bottom of the suction baffle 8 penetrates the cleaning tank 1 and extends into the interior of the cleaning tank 1. A motor 10 is fixedly connected inside the motor cylinder 9. The output shaft of the motor 10 is fixedly connected to a drive shaft 11 via a coupling. The bottom end of the drive shaft 11 penetrates the suction baffle 8 and extends into the interior of the suction baffle 8. A suction impeller 12 is fixedly connected to one end of the drive shaft 11 located inside the suction baffle 8. During operation, multiple arc-shaped sleeves 5 and rotating scrapers 6 are arranged equidistantly inside the cleaning tank 1 to increase the sludge scraping range and improve the sludge scraping effect. In addition, an air suction baffle 8 is set with filter holes at the bottom to allow water to pass through while preventing sludge from entering. At the same time, the air suction baffle 8 can also support the motor cylinder 9. The motor cylinder 9 has a fixed support for the motor 10. After the motor 10 starts working, it drives the transmission shaft 11 to start rotating through the output shaft. After the transmission shaft 11 rotates, it drives the air suction impeller 12 to start rotating, thereby generating centrifugal force, which agitates the water inside the cleaning tank 1 and sucks it upward, thereby moving the sludge in the water upward.

[0028] Furthermore, such as Figure 3 and Figure 4 As shown, a water perforation plate 13 is fixedly connected to the inner wall of the cleaning tank 1, and a conical anti-backflow hood 14 is fixedly connected to the top of the water perforation plate 13. Two conical anti-backflow hoods 14 and two air intake baffles 8 are provided, and the two conical anti-backflow hoods 14 and two air intake baffles 8 are symmetrically arranged on the top of the water perforation plate 13, with the two conical anti-backflow hoods 14 positioned directly below the two air intake baffles 8. During operation, the water passage plate 13 is set on the wedge-shaped platform 3 fixed to the inner wall of the cleaning tank 1, allowing water carrying sludge to pass through. A conical anti-backflow hood 14 is supported on top of the plate. After the water carrying sludge is driven through by centrifugal force, it will be thrown off at the top of the conical anti-backflow hood 14, thus throwing the sludge out of the opening of the conical anti-backflow hood 14 until it lands on the surface of the conical anti-backflow hood 14. This achieves the goal of leaving the sludge on the conical anti-backflow hood 14 after passing through it, thereby realizing the function of sludge recycling and further improving the adaptability of the treatment.

[0029] Working principle: First, the sludge scraping assembly is installed inside the cleaning tank 1. The moving wheels 7 drive the cleaning tank 1 to move in the water. Two wedge-shaped platforms 3 are installed at both ends of the electric telescopic rod 2, which allows the electric telescopic rod 2 to be tilted and also supports it. After the electric telescopic rod 2 is in operation, it extends and retracts, thereby driving the moving plate 4 to move back and forth. After the moving plate 4 moves, it drives the arc-shaped sleeve 5 to move, which in turn drives the rotating scraper 6 to rotate inside the cleaning tank 1, thus scraping the sludge. By setting up the sludge scraping assembly, the cleaning tank 1 can be placed in the water and moved. When working, the rotating scraper 6 can scrape the sludge in the water, which can quickly process the sludge in the water and improve the overall work efficiency. Then, multiple arc-shaped sleeves 5 and rotating scrapers 6 are arranged equidistantly inside the cleaning tank 1 to increase the sludge scraping range and improve the sludge scraping effect. In addition, an air suction baffle 8 is set with filter holes at the bottom to allow water to pass through while preventing sludge from entering. At the same time, the air suction baffle 8 can also support the motor cylinder 9. The motor cylinder 9 has a fixed support for the motor 10. After the motor 10 is working, it drives the transmission shaft 11 to start rotating through the output shaft. After the transmission shaft 11 rotates, it drives the air suction impeller 12 to start rotating, thereby generating centrifugal force, which agitates the water inside the cleaning tank 1 and sucks it upward, thereby causing the sludge in the water to move upward. Finally, the water passage plate 13 is set on the wedge-shaped platform 3 fixed to the inner wall of the cleaning tank 1, allowing water carrying sludge to pass through. A conical anti-backflow hood 14 is supported on top of the plate. After the water carrying sludge is driven through by centrifugal force, it will be thrown off at the top of the conical anti-backflow hood 14, thus throwing the sludge out of the opening of the conical anti-backflow hood 14 until it lands on the surface of the conical anti-backflow hood 14. This achieves the goal of leaving the sludge on the conical anti-backflow hood 14 after passing through it, thereby realizing the function of sludge recycling and further improving the adaptability of the treatment.
