Description

Technical Field

[0001] The utility model relates to the technical field of filter tank cleaning, in particular to a bottom silt removal device for a filter cloth filter tank. Background Art

[0002] A cloth filter is a type of water treatment equipment that utilizes filter cloth for filtration. It is primarily used to remove solid particles from liquids, achieving clarification and purification through the use of a specific filter cloth material and pore size. The main components of a cloth filter are the filter cloth, the filter tank, and a supporting structure. The filter tank is typically an open container with a filter cloth suspended within it, forming a filter layer. During operation, liquid flows into the filter tank and is filtered through the filter cloth. Solid particles are intercepted by the cloth, while clear liquid flows out through it. During the filtration process, solid particles, suspended matter, and sediment are captured by the filter cloth or filter layer. These captured solids gradually accumulate at the bottom of the filter tank, forming sludge. As the filtration process progresses, the sludge layer continues to thicken.

[0003] Existing fabric filter bottom desilting methods involve using PVC pipes to remove silt. These pipes are drilled with plum blossom-shaped holes and connected to a water pump for suction. However, the pump's suction force is weak and its suction range is limited, resulting in only the silt near the holes being sucked up. Over time, the silt can bury the pipes, rendering them ineffective and affecting the water quality.

[0004] Therefore, we propose a filter cloth filter bottom desilting device to solve the above problems. Utility Model Content

[0026] Specific examples Figure 3 As shown, the scraper track 2 includes a track bracket 21, and a rotating shaft 22 is rotatably installed at both ends of the bracket 21.

A driving motor 7 is provided on the top of the filter tank 1, and a driving gear 8 is provided on the rotating shaft of the driving motor 7. One end of one of the rotating shafts 22 extends to the outside of the track bracket 21 and is fixed with a driven gear 9. The driven gear 9 and the driving gear 8 are engaged through a synchronous chain 10.

[0027] When in use, the driving motor 7 drives the rotating shaft 22 to rotate through the driving gear 8, the driven gear 9 and the synchronous chain 10, and then drives the synchronous belt 24 to move. When the synchronous belt 24 moves, it drives the sludge scraper 3 to move. When the sludge scraper 3 moves, it scrapes the sludge remaining at the bottom of the filter tank 1 and pushes it into the sludge collecting tank 4 for centralized collection. Then, the sludge in the sludge collecting tank 4 is extracted and cleaned through the sludge suction pump 5 and the sludge suction pipe 6. Compared with the traditional flower pipe suction method, the cleaning range is larger and the sludge cleaning is more thorough.

The external controller controls the servo motor to reverse, so that the sludge scraper 3 can scrape and clean the sludge when moving left and right, so as to avoid the scraper from idling when resetting, and further improve the dredging efficiency.
