Description

Technical Field

[0001] This utility model relates to the field of sewage treatment equipment, and in particular to a sedimentation tank cleaning device for sewage treatment. Background Technology

[0002] Sedimentation tanks are structures that remove impurities from water through sedimentation. They are widely used in wastewater treatment. After a period of use, sedimentation tanks need to be cleaned. For example, Chinese utility model patent CN220530757U discloses a cleaning device for mud sedimentation tanks in water conservancy projects. The device includes a sedimentation tank body and a scraping device for cleaning sedimented mud. The scraping device includes an overflow plate on the sedimentation tank body, a steel frame on the sedimentation tank body, a motor on the steel frame, a rotating shaft on the motor, a fixed platform fixed to the bottom of the sedimentation tank body, an annular groove on the fixed platform, a connecting platform fixed to the rotating shaft, multiple suction pipes fixed to the connecting platform, a sludge scraper fixed to one end of the suction pipe, multiple suction ports on the sludge scraper, and a suction pump on the suction pipe. The cleaning device is equipped with a sludge scraper to remove sediment from the bottom of the sedimentation tank. However, because sediment adheres to the bottom of the sedimentation tank for a long time during the sewage treatment process, the effect of cleaning the bottom of the substrate tank by the sludge scraper alone is not ideal. There are dead corners in the sludge scraping during the operation of the sludge scraper, which means that the sludge in some areas cannot be effectively cleaned. Utility Model Content

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0023] Example: A sedimentation tank cleaning device for sewage treatment, including a rotating scraper frame 1 installed inside the sedimentation tank, as shown in the attached diagram.

A movable seat 12 is mounted on the track 11. A traveling wheel 13 connected to a motor is mounted on the movable seat 12. The traveling wheel 13 is in contact with the plane of the track 11. The main rod 3 is connected to the movable seat 12 via a bearing. The motor controls the rotation of the traveling wheel. The traveling wheel moves along the track. The components on the movable seat can move along the track. A support rod 4 is mounted at the end of the main rod 3. A swing rod 5 is mounted at the end of the support rod 4. A sweeping wheel assembly 6 is provided at the end of the swing rod 5. A first cylinder rod 7 is provided between the support rod 4 and the swing rod 5 to adjust the longitudinal swing of the sweeping wheel assembly 6, as shown in the attached figure. Figure 2 As shown; the sweeping wheel assembly can move along the track, expanding the cleaning range and reducing cleaning dead spots. A fastening element 8 is installed in the middle of the support rod 4, as shown in the attached diagram. Figure 3 As shown, one end of the fastener 8 is mounted with a connecting rod 9 via a pivot. The moving end of the moving assembly 2 is hinged to a second cylinder rod 10 that adjusts the lateral swing of the sweeping wheel assembly 6. The extended end of the second cylinder rod 10 is hinged to one end of the connecting rod 9. A horizontal plate 14 is mounted at the front end of the moving seat 12. A hinge seat 15 is located on the surface of the horizontal plate 14. The second cylinder rod 10 is connected to the hinge seat 15, resulting in a simple structure and convenient installation of the second cylinder rod. The swing rod 5 has a hollow structure, with a central shaft 16 passing through it. The end of the central shaft 16 is fixed to the swing rod 5 via a double-nut structure. The swing rod and the central shaft are connected by a double-nut structure, facilitating the assembly and disassembly of the sweeping wheel assembly. The detachable structure includes an angle seat 24 connected to the rotating scraper frame 1, as shown in the attached diagram. Figure 6 As shown, the end of the track 11 is provided with a locking member 25, which engages with the corner seat 24 and is connected to the corner seat 24 by bolts. After the water cup is removed from the sedimentation tank, sediment is left in the tank. The rotating scraper frame removes the dirt, leaving dirt that is difficult to clean. The locking member is engaged with the corner seat, and then the bolts are installed so that the track is connected to the rotating scraper frame.

[0024] The sweeping wheel assembly 6 includes a central shaft 16 connected to the end of the swing arm 5, as shown in the attached figure. Figure 4 As shown, a housing 17 is provided at one end of the central shaft 16, a rotary motor 18 is provided inside the housing 17, and a main shaft 19 is provided inside the housing 17. The rotating end of the rotary motor 18 is connected to the main shaft 19 via a bevel gear set. One end of the main shaft 19 extends to support the outside of the housing 17, and a sweeping wheel 20 is installed at the outer end of the main shaft 19. The first and second cylinder rods have different functions. The first cylinder rod controls the contact degree between the sweeping wheel and the bottom of the sedimentation tank. For shallowly adhered sediment, the sweeping wheel can be raised at a certain angle, resulting in a lower contact degree between the brush surface of the sweeping wheel and the bottom of the sedimentation tank. For deeply adhered sediment, the sweeping wheel can be lowered at a certain angle, resulting in a higher contact degree between the brush surface of the sweeping wheel and the bottom of the sedimentation tank. The second cylinder rod controls the tilt of the sweeping wheel, causing the brush surface of the sweeping wheel to be angled to one side. This method can be used for some stubborn sediment, reducing the contact area with the bottom of the sedimentation tank, increasing the sweeping force, and helping to better remove sediment from the bottom of the sedimentation tank, thus improving the cleaning effect. The sweeping wheel 20 includes a wheel frame 21 connected to the outer end of the main shaft 19, as shown in the attached figure. Figure 5 As shown, the outer side of the wheel frame 21 has a wheel ring 22, and the outer side of the wheel ring 22 has a steel wire strip 23. The steel wire strip has a good cleaning force, which helps to improve the cleaning effect of the sedimentation tank.

[0025] The working principle of this invention is as follows: First, the water in the sedimentation tank is pumped out, leaving the sediment. A rotating scraper frame removes most of the sediment. For stubborn, sticky sediment, a sweeping wheel assembly is used. The moving component is detachably mounted on the rotating scraper frame. This moving component is the basis for the sweeping wheel assembly's movement. The rotating scraper frame has a track, and the moving seat moves along the track via wheels driven by a motor. This movement causes the main rod, support rod, swing arm, and sweeping wheel assembly mounted on the moving seat to move together. This movement allows the sweeping wheel assembly to change position within the area covered by the rotating scraper frame, expanding the cleaning range and effectively reducing cleaning dead zones. When the sediment at the bottom of the sedimentation tank has varying degrees of adhesion, the contact between the sweeping wheel and the bottom of the sedimentation tank needs to be adjusted. For shallowly adhered sediment, the first cylinder rod retracts, causing the swing arm and sweeping wheel assembly to lift upwards at a certain angle. At this point, the brush surface of the sweeping wheel contacts the bottom of the sedimentation tank. For lower sediment, cleaning is performed with less pressure. However, for deeper, more stubborn sediment, the first cylinder rod extends, lowering the swing arm and sweeping wheel assembly by a certain angle. This increases the contact between the brush surface of the sweeping wheel and the bottom of the sedimentation tank, increasing cleaning pressure and ensuring effective removal of stubborn sediment. The second cylinder rod is hinged at one end to the moving end of the moving assembly, and the other end is connected to the fastener via a connecting rod. This controls the lateral swing of the sweeping wheel assembly. When encountering more stubborn sediment, the second cylinder rod extends or retracts, pushing the connecting rod to rotate around the axis of the fastener. This causes the swing arm and sweeping wheel assembly to tilt laterally, tilting the brush surface of the sweeping wheel to one side. This reduces the contact area between the sweeping wheel and the bottom of the sedimentation tank. According to the relationship between pressure and area, under the same force, a smaller contact area increases the cleaning force, helping to better remove these stubborn sediments. When the sweeping wheel rotates to clean the sediment, the main shaft drives the wheel frame and wheel ring to rotate. The steel wire strip on the outside of the wheel ring rotates accordingly, cleaning the sediment at the bottom of the sedimentation tank. Steel wire has good cleaning power and can effectively scrape and remove deposits.
