Technical Field

[0001] This utility model belongs to the field of filter cloth cleaning technology for sludge dewatering machines, specifically a filter cloth cleaning and slag removal device for sludge dewatering machines. Background Technology

[0002] In the sludge treatment process, the filter cloth of the sludge dewatering machine plays a crucial role, effectively separating water from the sludge and improving dewatering efficiency. However, with increased usage time, a large amount of sludge residue gradually accumulates on the filter cloth. This residue not only clogs the pores of the filter cloth, reducing filtration performance, but also increases the difficulty of cleaning and the frequency of replacement, thereby increasing the cost of sludge treatment.

[0003] Common filter cloth cleaning methods mainly include high-pressure water jet rinsing and chemical soaking. While high-pressure water jet rinsing can remove sludge from the surface of the filter cloth to some extent, it is difficult to completely remove residues deep within the pores of the filter cloth. Moreover, the impact of the high-pressure water jet may damage the structure of the filter cloth, shortening its service life. Chemical soaking poses environmental pollution risks, and the wastewater treatment cost after cleaning is high.

[0004] Therefore, developing a filter cloth cleaning and slag removal device for sludge dewatering machines that can conveniently clean filter cloths, remove residues, and is energy-saving and environmentally friendly has important practical significance. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide a filter cloth cleaning and slag removal device for sludge dewatering machines, which has the advantages of convenient filter cloth cleaning, slag removal, energy saving and environmental protection.

[0006] This utility model provides the following technical solution: a filter cloth cleaning and slag removal device for a sludge dewatering machine, comprising a box body, an inner cylinder structure, a placement rack structure, a bottom box, a filter bottom shell structure, a drive source structure, and a circulating spray structure. The inner cylinder structure is located inside the box body, and a gap is left between the outer surface of the inner cylinder structure and the inner wall of the box body. The placement rack structure is located inside the inner cylinder structure and is used to place the filter cloth to be cleaned. The bottom box is installed at the bottom of the box body. The filter bottom shell structure is located on the side inside the bottom box, and the top of the filter bottom shell structure is connected to the bottom of the placement rack structure for filtering the cleaning water. The bottom of the filter bottom shell structure extends to the bottom of the bottom box. The drive source structure is located on the side inside the bottom box and is used to drive the inner cylinder structure to rotate. The circulating spray structure is located on the side of the box body. The input end of the circulating spray structure extends into the interior of the bottom box and is connected to the side of the filter bottom shell structure. The output end of the circulating spray structure extends into the interior of the box body and is used to spray water to clean the filter cloth inside the inner cylinder structure.

[0007] The beneficial effects of this utility model are as follows:

[0008] 1. This utility model provides ample space for the cleaning process by placing the inner cylinder structure inside the housing and leaving a gap between it and the inner wall of the housing, allowing for better flow and circulation of the cleaning water.

The circulating spray structure reintroduces the filtered water into the housing to spray and clean the filter cloth, achieving water recycling, saving water resources, improving cleaning efficiency, and ensuring a more comprehensive and thorough cleaning of the filter cloth.

[0009] 2. This utility model, through the design of the vertical groove, allows the cleaning water to enter the rotating cylinder more smoothly and come into contact with the filter cloth, improving the flow of the cleaning water. The permeable mesh plate not only ensures the smooth passage of the cleaning water but also prevents the filter cloth from being sucked into the vertical groove, thus protecting the filter cloth. The soft rubber rods arranged alternately on the inner wall of the rotating cylinder can knock and vibrate the filter cloth when the cylinder rotates, which can effectively remove the residue attached to the filter cloth and make it easier for the residue to fall off the filter cloth, improving the cleaning effect of the filter cloth. Especially for some stubborn residues, the knocking action of the soft rubber rods can make them more easily detach from the filter cloth. Attached Figure Description

[0023] In this embodiment, by connecting the filter box 14 to the bottom of the support base 11, the wastewater after cleaning can be collected and filtered in a timely manner. The slots on the inner wall of the filter box 14 and the inserted filter element 15 facilitate the installation and replacement of the filter element 15. The filter element 15 can effectively filter impurities and residues in the wastewater, purifying the cleaning water and providing a clean water source for the circulating spray structure 7, ensuring the quality of the circulating water. The design of the detachable sealed bottom shell 16 and the drain valve pipe facilitates the cleaning and maintenance of the inside of the filter box 14. When a certain amount of residue accumulates in the filter box 14, the sealed bottom shell 16 can be opened for cleaning. The drain valve pipe can discharge the wastewater inside the device after cleaning, ensuring the normal operation of the device.

[0024] refer to Figure 2 The drive source structure 6 includes a drive motor 17 fixedly connected to the inside side of the bottom box 4 and an internal gear ring 18 fixedly connected to the bottom of the rotating cylinder 8. A gear 19 is fixedly connected to the output end of the drive motor 17, and the surface of the gear 19 meshes with the inner surface of the internal gear ring 18.

[0025] In this embodiment, the stable rotation of the rotating drum 8 is achieved through the cooperation of the drive motor 17, gear 19, and internal gear ring 18. The drive motor 17 provides power, and the meshing transmission between the gear 19 and the internal gear ring 18 is stable and reliable, accurately transmitting the power of the drive motor 17 to the rotating drum 8, causing the rotating drum 8 to rotate at a predetermined speed and direction. This stable rotation ensures that the soft rubber rod 10 effectively taps and vibrates the filter cloth, thereby improving the cleaning effect of the filter cloth.

[0026] refer to Figure 3 The circulating spray structure 7 includes a circulating pump 20 fixedly connected to the side of the housing 1. The input end of the circulating pump 20 extends into the interior of the bottom box 4 and is connected to the side of the filter box 14. The output end of the circulating pump 20 is connected to a three-way pipe 21. The two output ends of the three-way pipe 21 extend into the front and rear sides of the interior of the housing 1 and are connected to the spray rows 22 corresponding to the vertical groove.

[0027] In this embodiment, a circulating pump 20 draws filtered water from the bottom tank 4 and reintroduces it into the housing 1 through a three-way pipe 21 and a spray nozzle 22 to clean the filter cloth. The spray nozzle 22 corresponds to the vertical trough, ensuring the cleaning water is accurately sprayed onto the filter cloth, improving the targeting and effectiveness of the cleaning. Recycling the cleaning water not only saves water resources but also reduces dependence on external water sources, lowering operating costs. Simultaneously, the circulating spray structure 7 ensures the filter cloth is continuously impacted by the water flow during the cleaning process, further enhancing the cleaning effect and ensuring a more thorough cleaning of the filter cloth.

The use of sealing bearings also reduces friction and wear between components, extends the service life of the device, and ensures its stability and reliability during long-term operation.

[0032] The filter cloth is secured to the filter cloth holder 13 with clips or rubber bands. The horizontal round rod at the top of the filter cloth holder 13 allows the filter cloth to be unfolded more stably. Then, sufficient water is added into the device from the top of the rotating cylinder 8. The device drive motor 17 and waterproof motor 12 are started to drive the rotating cylinder 8 and the placement frame to rotate slowly in opposite directions intermittently. The drive motor 17 drives the rotating cylinder 8 to rotate through the meshing of the gear 19 and the internal gear ring 18, while the waterproof motor 12 drives the filter cloth holder 13 to rotate, so that the filter cloth is in full contact with the cleaning water during the rotation. The soft rubber rods 10 arranged alternately on the inner wall of the rotating cylinder 8 will knock and vibrate the filter cloth, thereby removing the residue attached to the filter cloth. The cleaning water starts from the circulation pump 20 of the circulating spray structure 7, drawing out the water that has been filtered by the filter bottom shell structure 5 in the bottom tank 4, and spraying it into the box 1 through the three-way pipe 21 and the spray nozzle 22 corresponding to the vertical groove to spray water to clean the filter cloth. During the cleaning process, wastewater flows into the filter box 14 through the water channel on the surface of the support seat 11. The filter element 15 in the filter box 14 filters the wastewater to remove impurities and residues. The filtered water is then reintroduced into the box 1 by the circulation pump 20 for recycling.
