Description

Technical Field

[0001] This utility model relates to the field of secondary sedimentation tank technology, and more specifically, to a sludge removal device for secondary sedimentation tanks. Background Technology

[0002] Secondary sedimentation tanks, also known as secondary settling tanks, are an important component of activated sludge systems in wastewater treatment processes. Their function is to clarify, concentrate, and return activated sludge to the mixed liquor. In the secondary sedimentation tank, the mixed liquor after biological treatment undergoes sludge-water separation. The settled activated sludge is returned to the front end of the biological treatment structure, while the treated water is discharged. During the operation of the secondary sedimentation tank, floating sludge will occur. If the floating sludge generated in the secondary sedimentation tank is not cleaned in a timely manner, it will not only affect the effluent quality and reduce the wastewater treatment effect, but may also cause the floating sludge to clump together, block the sludge discharge port, affect the normal operation of the secondary sedimentation tank, and even shorten its service life.

[0003] Currently, existing secondary sedimentation tanks have some drawbacks: 1. When faced with floating sludge that is easily clumped in the environment, the scrapers have difficulty cleaning it thoroughly; 2. The cleaning device is difficult to adapt to the cleaning needs of floating sludge in different locations, making it difficult to guarantee cleaning efficiency and quality.

[0004] Therefore, there is an urgent need for a sludge removal device for secondary sedimentation tanks to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a sludge removal device for a secondary sedimentation tank to solve the problems mentioned in the background art.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0007] A sludge removal device for a secondary sedimentation tank includes a support platform, a maintenance walkway frame fixedly connected to the top wall of the support platform, an installation frame fixedly connected to the outer wall of the maintenance walkway frame, and a drive motor fixedly connected to the top wall of the installation frame. The device also includes:

[0008] An anti-caking water spray assembly includes a fixed water pipe fixedly connected to the outer wall of the maintenance walkway frame, a uniformly distributed connecting hose A fixedly connected to the outer wall of the fixed water pipe, a rotating water pipe fixedly connected to the end of the connecting hose A away from the fixed water pipe, a uniformly distributed connecting hose B fixedly connected to the outer wall of the rotating water pipe, a water spraying disc fixedly connected to the outer wall of the connecting hose B, and a water spraying pipe fixedly connected to the outer wall of the water spraying disc.

[0009] An up-and-down angle adjustment component is installed on the outer wall of the fixed water pipe;

[0010] The left and right angle adjustment component is located on the outer wall of the mounting bracket.

[0011] As a preferred technical solution of this application, the up and down angle adjustment component includes a rotating frame symmetrically rotatably connected to the outer wall of the fixed water pipe, a drive frame fixedly connected to the top wall of the outer wall of the rotating frame, a worm gear fixedly connected to the outer wall of the drive frame, and evenly distributed linkage plates fixedly connected to the outer wall of the drive frame, with a positioning plate fixedly connected to the end of the linkage plate away from the drive frame.

[0012] As a preferred technical solution of this application, the left and right angle adjustment component includes a rotating base rotatably connected to the outer wall of the mounting frame. An electric push rod is fixedly connected to the outer wall of the rotating base. A moving plate is fixedly connected to the output end of the electric push rod. The outer walls of the moving plate and the positioning plate are both rotatably connected with evenly distributed positioning rods, and the positioning rods are fixedly connected to the water spray plate.

[0013] As a preferred technical solution of this application, the output end of the drive motor is fixedly connected to a worm, and the outer wall of the worm is meshed with the outer wall of the worm wheel.

[0014] As a preferred technical solution of this application, the top wall of the support platform is fixedly connected to the body of the secondary sedimentation tank, the outer wall of the body of the secondary sedimentation tank is fixedly connected to the water inlet pipe, and the water inlet pipe is fixedly connected to the support platform.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In the scheme of this application:

[0017] 1. By spraying water onto the water surface through the anti-caking water spray component, the floating sludge that is easily caking in the environment can be dispersed, avoiding the problem of the scraper not cleaning the sludge properly due to caking. This greatly improves the efficiency and quality of sludge cleaning in the secondary sedimentation tank and solves the problem in the existing technology that the scraper cannot clean the sludge that is easily caking in the environment.

[0018] 2. By setting up vertical and horizontal angle adjustment components, the water spray pipe can spray water at multiple angles, covering the floating mud in different areas of the secondary sedimentation tank. Whether it is clumps of floating mud near the tank wall or in the center of the tank, it can be effectively dispersed, which enhances the adaptability of the floating mud cleaning device to different working conditions and solves the problem that the existing cleaning devices are difficult to adapt to the cleaning needs of floating mud in different locations, making it difficult to guarantee cleaning efficiency and quality.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0027] like Figure 1-5 As shown, the sludge cleaning device for a secondary sedimentation tank proposed in this embodiment includes a support platform 1, a maintenance walkway frame 3 fixedly connected to the top wall of the support platform 1, an installation frame 10 fixedly connected to the outer wall of the maintenance walkway frame 3, and a drive motor 16 fixedly connected to the top wall of the installation frame 10. It also includes:

[0028] The anti-caking water spray assembly includes a fixed water pipe 4 fixedly connected to the outer wall of the maintenance walkway frame 3. The outer wall of the fixed water pipe 4 is fixedly connected with evenly distributed connecting hoses A5. The end of the connecting hoses A5 away from the fixed water pipe 4 is fixedly connected to a rotating water pipe 6. The outer wall of the rotating water pipe 6 is fixedly connected with evenly distributed connecting hoses B7. The outer wall of the connecting hoses B7 is fixedly connected to a spray plate 8. The outer wall of the spray plate 8 is fixedly connected to a spray pipe 9. When clumps of floating sludge appear in the secondary sedimentation tank body 22, water flows in from the inlet pipe 2, passes through the fixed water pipe 4, flows through the connecting hoses A5 into the rotating water pipe 6, then through the connecting hoses B7 to the spray plate 8, and finally sprays out from the spray pipe 9 to disperse the clumps of floating sludge, preparing for subsequent scraper cleaning of floating sludge.

[0029] The up-and-down angle adjustment component is installed on the outer wall of the fixed water pipe 4;

[0030] The left and right angle adjustment component is located on the outer wall of the mounting bracket 10.

[0031] like Figure 3-4 As shown, in a preferred embodiment, based on the above method, the upper and lower angle adjustment assembly further includes a rotating frame 11 symmetrically rotatably connected to the outer wall of the fixed water pipe 4. A drive frame 12 is fixedly connected to the top wall of the outer wall of the rotating frame 11. A worm gear 18 is fixedly connected to the outer wall of the drive frame 12. A uniformly distributed linkage plate 13 is fixedly connected to the outer wall of the drive frame 12. A positioning plate 14 is fixedly connected to the end of the linkage plate 13 away from the drive frame 12. When the drive motor 16 starts, the worm 17 at its output end rotates. Since the worm 17 meshes with the worm gear 18, it drives the worm gear 18 to rotate. The worm gear 18 is fixed on the drive frame 12, thereby causing the drive frame 12 and the rotating frame 11 connected to it to rotate on the outer wall of the fixed water pipe 4. At the same time, the linkage plate 13 and the positioning plate 14 rotate accordingly, realizing the adjustment of the upper and lower angles of the water spray pipe 9 to meet the needs of dispersing clumps of floating mud at different positions.

[0032] like Figure 3 and Figure 5 As shown, in a preferred embodiment, based on the above method, the left and right angle adjustment component further includes a rotating seat 20 rotatably connected to the outer wall of the mounting frame 10. An electric push rod 21 is fixedly connected to the outer wall of the rotating seat 20. A moving plate 15 is fixedly connected to the output end of the electric push rod 21. The moving plate 15 and the outer wall of the positioning plate 14 are both rotatably connected to evenly distributed positioning rods 19, and the positioning rods 19 are fixedly connected to the spray plate 8. When the electric push rod 21 is activated, its output end pushes the moving plate 15 to move, thereby driving the positioning rods 19 on the moving plate 15 to move, thereby driving the spray plate 8 and the spray pipe 9 to rotate along the positioning rods 19 on the positioning plate 14. The rotating seat 20 adaptively rotates on the outer wall of the mounting frame 10, so that the spray pipe 9 can achieve left and right angle adjustment, further expanding the spray range and ensuring that the clumps of floating mud in all directions can be dispersed.

[0033] like Figure 4 As shown, in a preferred embodiment, based on the above method, the output end of the drive motor 16 is further fixedly connected to a worm 17, and the outer wall of the worm 17 is meshed with the outer wall of the worm wheel 18. The self-locking structure of the worm 17 and the worm wheel 18 can fix the position after the water spray angle is adjusted.

[0034] like Figure 1 As shown, in a preferred embodiment, based on the above method, the top wall of the support platform 1 is further fixedly connected to the secondary sedimentation tank body 22, the outer wall of the secondary sedimentation tank body 22 is fixedly connected to the water inlet pipe 2, and the water inlet pipe 2 is fixedly connected to the support platform 1. The sludge enters the secondary sedimentation tank body 22 through the water inlet pipe 2 for sludge cleaning operation.

[0035] Specifically, when the sludge removal device of this secondary sedimentation tank is in use: when clumps of sludge appear in the secondary sedimentation tank body 22, water flows in from the inlet pipe 2, passes through the fixed water pipe 4, flows through the connecting hose A5 into the rotating water pipe 6, then through the connecting hose B7 to the spray plate 8, and finally sprays out from the spray pipe 9, breaking up the clumps of sludge and preparing for subsequent scraper cleaning; the drive motor 16 starts, and the worm 17 at its output end rotates. Since the worm 17 meshes with the worm wheel 18, it drives the worm wheel 18 to rotate. The worm wheel 18 is fixed on the drive frame 12, thereby causing the drive frame 12 and the rotating frame 11 connected to it to rotate on the outer wall of the fixed water pipe 4, while simultaneously... The moving plate 13 and the positioning plate 14 rotate accordingly, thereby adjusting the up and down angle of the water spray pipe 9 to meet the needs of dispersing clumps of floating mud in different locations. At the same time, the self-locking structure of the worm gear 17 and worm wheel 18 can fix the position after the water spray angle is adjusted. The electric push rod 21 is activated, and its output end pushes the moving plate 15 to move, which in turn drives the positioning rod 19 on the moving plate 15 to move. This causes the water spray plate 8 and the water spray pipe 9 to rotate along the positioning rod 19 on the positioning plate 14. Meanwhile, the rotating seat 20 rotates adaptively on the outer wall of the mounting frame 10, so that the water spray pipe 9 can be adjusted to the left and right angles, further expanding the water spray range and ensuring that clumps of floating mud in all directions can be dispersed.

[0036] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
