Description

Technical Field

[0001] The utility model relates to the technical field of sedimentation tank cleaning, in particular to a flushing device installed on a sedimentation tank scraper. Background Art

[0002] Center-drive scrapers are widely used in existing sewage treatment plants. They are designed primarily for the sludge removal needs of circular sedimentation tanks. These scrapers consist of a motor-driven center drive system installed at the center of the sedimentation tank. The rotation of the drive shaft and related mechanical components drives a scraper bridge spanning the tank body to rotate. Scrapers are fixed beneath the scraper bridge, which rest close to the tank bottom and effectively scrape off the sludge deposited at the bottom. As the scraper bridge continues to rotate, the scrapers push the sludge toward the central sludge collection area of ​​the sedimentation tank, enabling centralized collection and removal for subsequent sludge treatment. However, current scraper designs typically focus only on cleaning the sludge at the bottom of the tank, while neglecting the removal of accumulated sludge at the bottom of the sedimentation tank and the need to clean the tank outlet trough and walls.

[0003] Due to the lack of a special cleaning mechanism, sludge accumulates on the edge of the inner wall of the sedimentation tank for a long time and easily forms stubborn lumps. It is difficult to scrape it off simply by relying on a rotating bridge-type curved scraper. In addition, aquatic organisms such as algae that are prone to breed in the outlet trough will produce unpleasant odors and may produce toxic substances after the organisms rot, thereby causing secondary pollution to the water body.

[0007] Furthermore, the brush rod is hinged on the frame of the scraper, and a spring is hinged on the end of the brush rod located at the frame. The spring is fixed on the frame to pull the brush rod so that the bristles of the brush rod are against the inner wall of the sedimentation tank.

[0008] Furthermore, an L-shaped brush plate is fixedly connected to the brush rod, and the brush plate matches the top corner of the wall of the sedimentation tank.

[0009] Furthermore, the nozzles on the water pipe are provided with two rows arranged in parallel and are respectively located on both sides of the brush rod.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] By installing two sets of brush rods and nozzles to regularly flush the moss on the outlet weir, the secondary pollution of the water body by sediment pollutants is reduced. This not only effectively removes the moss and ensures uniform water discharge, but also greatly improves the treatment effect and significantly improves the water quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0014] Figure 1 This is a schematic diagram of the cross-section structure of an embodiment of the present utility model.

[0015] In the above drawings: sedimentation tank 1, sludge scraper 2, brush rod 3, support frame 4, water pipe 5, submersible pump 6, upper clear water layer 7, nozzle 8, spring 9, brush plate 10. DETAILED DESCRIPTION

[0016] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0017] Please refer to Figure 1 As shown, a flushing device installed on a sedimentation tank scraper includes two brush rods 3, a support frame 4, a water pipe 5 and a submersible pump 6. The brush rod 3 is installed on the frame of the scraper 2 and is located on the inner wall side of the sedimentation tank 1. Bristles are fixed on the brush rod 3, and the bristles are hard steel bristles or plastic bristles. The support frame 4 is fixed on the frame of the scraper 2 and is located in the upper clear water layer 7 of the sedimentation tank 1. The end of the water pipe 5 is sealed, and the water pipe 5 is fixed on the support frame 4 and is arranged in an L shape. A number of nozzles 8 are installed on both sides of the water pipe 5, and the nozzles 8 face the inner wall of the sedimentation tank 1. The submersible pump 6 is fixed on the support frame 4 and connected to the water pipe 5.

[0018] The core principle of this device is to flush the sedimentation tank 1 regularly. When in use, turn on the switch on the nozzle 8, use the submersible pump 6 to extract the upper clear liquid of the sedimentation tank 1, and flush the inner wall of the sedimentation tank 1 through the nozzle 8. As the scraper 2 rotates, the bristles on the brush rod 3 clean the inner wall of the sedimentation tank 1. Cooperating with the action of the nozzle 8, the moss and other pollutants on the outlet weir are washed away. Rain, snow and ice can be flushed away in winter.

[0019] In this embodiment, the brush rod 3 is fixed on the frame of the mud scraper 2 and is arranged parallel to the inner wall of the sedimentation tank 1.

[0020] In this embodiment, please refer to Figure 1 As shown, the brush rod 3 is hinged on the frame of the scraper 2, and a spring 9 is hinged on the end of the brush rod 3 located at the frame. The spring 9 is fixed to the frame and is used to pull the brush rod 3 so that the bristles of the brush rod 3 are against the inner wall of the sedimentation tank 1. The spring 9 is used to adapt to the changes in the wall of the sedimentation tank 1 and improve the cleaning effect.

[0021] In this embodiment, please refer to Figure 1 As shown, an L-shaped brush plate 10 is fixedly connected to the brush rod 3, and the brush plate 10 cooperates with the top corner of the wall of the sedimentation tank 1. The brush plate 10 can clean the ice on the top of the wall of the sedimentation tank 1, facilitating the normal operation of the scraper 2 frame.

[0022] In this embodiment, the nozzles 8 on the water pipe 5 are provided with two rows arranged in parallel and respectively located on both sides of the brush rod 3. The two rows of nozzles 8 improve the flushing effect on the wall of the sedimentation tank 1 to improve the water quality.

[0023] In this embodiment, the nozzles 8 are staggered to expand the flushing range of the nozzles 8 and improve the flushing effect on the pool wall.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
