Description

Technical Field

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

[0002] The sedimentation tank after biological treatment is usually called the secondary sedimentation tank or the final sedimentation tank (final sedimentation tank). The function of the secondary sedimentation tank is to separate mud and water, clarify the mixed liquid, concentrate the sludge, and return the separated sludge to the biological treatment end. However, after long-term use, a large amount of adhesion will adhere to the inner wall of the secondary sedimentation tank. Therefore, it is necessary to use cleaning equipment to clean the adhesion. However, due to the large size of the secondary sedimentation tank, manual cleaning wastes a lot of manpower and material resources.

[0003] Patent CN219766275U discloses a secondary sedimentation tank cleaning device, comprising a transmission rod, a coupling provided on the transmission rod, a movable plate hinged on one side of the coupling, a connecting plate hinged on one end of the movable plate, a pair of swinging rods hinged on one side of the connecting plate, a brush hinged on one end of the pair of swinging rods, a spring connected to one side of the connecting plate and the swinging rods. After adopting the above scheme, cleaning is achieved through two sets of horizontal and vertical connecting rod mechanisms and spring tension. However, the transmission rod is driven to move by a separately provided power device. If the secondary sedimentation tank needs to be scraped and a sludge suction machine is provided, the cleaning device set up in this way needs to occupy a certain amount of space due to the separate drive device. This may affect the setting of the sludge suction machine or affect the subsequent operation of the sludge suction machine, resulting in the inability to suction sludge and clean the secondary sedimentation tank wall at the same time.

[0004] Therefore, a secondary sedimentation tank cleaning device is needed that can automatically complete the cleaning without the need for a separate driving device. Summary of the Invention

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present utility model.

[0026] The object of the present utility model is to provide a secondary sedimentation tank cleaning device to solve the problems existing in the prior art, enabling the simultaneous cleaning of the secondary sedimentation tank wall and bottom sludge suction and saving resources.

[0027] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] As Figure 1 shown, the present utility model provides a secondary sedimentation tank cleaning device, including a sludge suction device 13, a cleaning device, and a connecting member 3. The sludge suction device 13 is configured to be disposed at the bottom of the secondary sedimentation tank 14 and capable of rotating around the central axis of the secondary sedimentation tank to achieve bottom sludge suction. The first end of the connecting member 3 is fixedly connected to the rotating arm of the sludge suction device 13, the cleaning device is fixedly connected to the second end of the connecting member 3 and the cleaning device is in contact with the secondary sedimentation tank. The rotating arm of the sludge suction device 13 can drive the connecting member 3 to rotate, and the connecting member 3 can drive the cleaning device to rotate around the central axis of the connecting member. The cleaning device is used to clean the secondary sedimentation tank 14. Among them, it should be noted that in this embodiment, the cleaning device is mainly used to clean the side walls of the effluent triangular weir 4, the side walls of the effluent channel 2, and the scum baffle 5 of the secondary sedimentation tank 14. At this time, the height of the second end of the connecting member 3 should be higher than the height of the side wall of the effluent channel 2 of the secondary sedimentation tank 14 to meet the cleaning requirements of the cleaning device.

[0029] In this embodiment, the rotation of the sludge suction device 13 is used to drive the movement of the cleaning device, enabling the simultaneous cleaning of the secondary sedimentation tank wall and bottom sludge suction and saving resources. It should be noted that the side wall of the effluent channel 2 cleaned by the cleaning device is the side wall of the effluent channel 2 close to the effluent triangular weir 4, and the sludge suction device is a sludge suction machine.

[0030] In this embodiment, the connecting member 3 mainly includes a first support rod 31 and a second support rod 32. The first support rod 31 is arranged along the height direction of the secondary sedimentation tank 14. The second support rod 32 is perpendicular and fixedly connected to the first support rod 31, and the second support rod 32 is parallel to the top surface of the secondary sedimentation tank 14, facilitating the cleaning device to be smoothly arranged on the second support rod 32. It should be noted that the second support rod 32 is not necessarily perpendicular to the first support rod 31, and the second support rod 32 is not necessarily parallel to the top surface of the secondary sedimentation tank 14. As long as the cleaning device can be arranged on the second support rod 32 to clean the secondary sedimentation tank, the first support rod 31 is fixedly connected to the rotating arm of the sludge suction device 13. The rotation of the sludge suction device 13 drives the rotation of the first support rod 31, the rotation of the first support rod 31 drives the rotation of the second support rod 32, and the second support rod 32 drives the cleaning device to rotate, realizing the cleaning of the side walls of the effluent triangular weir 4 and the effluent channel 2 of the secondary sedimentation tank 14. It should be noted that the first support rod 31 and the second support rod 32 can be integrally designed or separately designed. The integral design means that the first support rod 31 and the second support rod 32 are integrally formed, and the separate design means that the first support rod 31 and the second support rod 32 are both separate rods, and the first support rod 31 and the second support rod 32 are fixedly connected by welding or other means.

[0031] In this embodiment, the secondary sedimentation tank cleaning device further includes a fixing rod 16. The fixing rod 16 is parallel to the first support rod 31.

It should be noted that on the premise of ensuring the reliable connection between the connecting member 3 and the sludge suction device 13, the fixing rod 16 can also not be provided. At the same time, in order to ensure high safety, multiple fixing rods 16 can also be provided.

[0032] In this embodiment, the cleaning device includes a first rotating brush 8 and a second rotating brush 9. The first rotating brush 8 is connected to the second support rod 32 through a first rotating brush fixing device 10, and the first rotating brush 8 can extend into the space clamped by the effluent triangular weir 4 and the scum baffle 5 of the secondary sedimentation tank 14 to clean the side walls of the effluent triangular weir 4 and the scum baffle 5; the second rotating brush 9 is connected to the second support rod 32 through a second rotating brush fixing device 15, and the second rotating brush 9 can extend into the effluent channel 2 of the secondary sedimentation tank 14 to clean the effluent channel 2.

[0033] In this embodiment, both the first rotating brush 8 and the second rotating brush 9 include a central shaft and a brush body. The brush body is arranged around the central shaft and wraps the central shaft. The central shaft is preferably a metal central shaft, and other types of central shafts can also be used, such as a central shaft made of composite materials.

[0034] In this embodiment, the brush body is an elastic plastic bundle. The upper end length of the elastic plastic bundle of the second rotating brush 9 is greater than the lower end length. The lower end elastic plastic bundle abuts against the side wall of the water outlet channel 2, and the upper end elastic plastic bundle can cover the clamping surface of the horizontal distance between the side wall of the water outlet channel 2 and the side wall of the water outlet triangular weir 4, and can clean the weir opening on the side of the water outlet channel 2. It is necessary to ensure that the longer part of the upper end of the elastic plastic bundle can abut against the weir opening, and the elastic plastic bundle has sufficient strength to fully ensure the cleaning ability.

[0035] In this embodiment, the first rotating brush 8 is rotatably connected to the first rotating brush fixing device 10. The first rotating brush fixing device 10 is fixed to the second support rod 32 by a square clip, and the first rotating brush 8 can freely rotate under the friction of the side wall of the water outlet triangular weir 4; the second rotating brush 9 is rotatably connected to the second rotating brush fixing device 15. The second rotating brush fixing device 15 is fixed to the second support rod 32 by a square clip, and the second rotating brush 9 can freely rotate under the friction of the side wall of the water outlet channel 2. The rotating brush can rotate relative to the rotating brush fixing device, which ensures the multi-angle friction of the rotating brush with the side wall of the secondary sedimentation tank 14, and ensures that the 360 degrees of the rotating brush can all play a cleaning role, avoiding only fricturing one position of the rotating brush and making the rotating brush more durable.

[0036] In this embodiment, the secondary sedimentation tank cleaning device further includes a tension device and a tension rod 17. The tension rod 17 is fixedly arranged on the second support rod 32, and the tension rod 17 and the second rotating brush fixing device 15 are respectively located on both sides of the first rotating brush fixing device 10. The tension device includes a tension adjusting device 11 and a tension spring 12.

One end of the tension spring 12 is fixed to the first rotating brush fixing device 10, and the other end is fixed to the second rotating brush fixing device 15. The tension spring 12 is used to ensure that the friction force between the first rotating brush 8 and the side wall of the water outlet triangular weir 4 and the friction force between the second rotating brush 9 and the side wall of the water outlet channel 2 can meet the cleaning requirements. The tension adjusting device 11 is used to adjust the tension force of the first rotating brush fixing device 10 relative to the tension rod 17. The tension adjusting device 11 tightens the first rotating brush 8 to ensure the relative position of the first rotating brush 8, that is, it is necessary to ensure that the first rotating brush 8 can extend into the clamping space between the water outlet triangular weir 4 and the scum baffle 5. The tension spring 12 can adapt to the situation where the concentricity of the secondary sedimentation tank wall changes slightly, and can ensure the friction force between the second rotating brush 9 and the side wall of the water outlet channel 2 and the friction force between the first rotating brush 8 and the water outlet triangular weir 4.

[0037] In this embodiment, the tension adjusting device 11 is a turnbuckle. Optionally, there are CC type turnbuckles, OC type turnbuckles, OO type turnbuckles, etc.

[0038] In this embodiment, the secondary sedimentation tank cleaning device further includes a scum scraping plate 6. The scum scraping plate 6 is fixedly arranged on the second support rod, and the height of the second support rod is higher than the height of the distribution channel 1 of the secondary sedimentation tank. The scum scraping plate 6 can also be driven by the sludge suction device 13. The scum scraping plate 6 is used to scrape the scum on the water surface of the distribution channel 1 of the secondary sedimentation tank, and there is no need to separately set a driving device, saving resources.
