Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a sludge removal device for the upper part of a sedimentation tank. Background Technology

[0002] In wastewater treatment, sedimentation tanks are crucial equipment for separating solid particles and sludge from water. However, in some special cases, the bottom of the sedimentation tank may have a complex structure, geological conditions may prevent the installation of bottom sludge discharge equipment, or the bottom sludge discharge equipment may be damaged and difficult to repair, making it impossible to perform normal sludge discharge from the bottom of the sedimentation tank. Traditional sludge discharge methods mostly rely on equipment such as bottom sludge discharge pipes and sludge pumps. When bottom sludge discharge is not feasible, sludge will continuously accumulate in the sedimentation tank, affecting the normal operation of the sedimentation tank and the wastewater treatment effect, reducing its separation efficiency, and may even lead to substandard effluent quality. Utility Model Content

[0003] The purpose of this invention is to provide a sludge removal device for the upper part of a sedimentation tank, which has the advantage of effectively removing sludge from the upper part of the sedimentation tank.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a sedimentation tank upper air-lift sludge removal device, comprising a sedimentation tank, a support plate disposed above the sedimentation tank, a movable seat disposed on the left side of the top of the support plate, movable rods slidably mounted on both sides of the bottom of the movable seat, the bottom of the movable rods being fixedly installed to the top of the support plate, a sludge pipe being sleeved inside the movable seat, the lower end of the sludge pipe extending to the bottom of the inner cavity of the sedimentation tank, and the other end extending to the outside of the sedimentation tank, an air compressor being fixedly installed on the right side of the top of the support plate, an air pipe being connected to the front of the air compressor through a pipeline, the lower end of the air pipe extending into the interior of the sedimentation tank and connected to the lower end of the sludge pipe through a branch pipe.

[0005] As a preferred embodiment, a fixing seat is fixedly installed at both the upper and lower ends of the side of the sedimentation tank. A guide groove is opened inside the fixing seat, and a guide slider is slidably installed on the upper part of the guide groove.

[0007] As a preferred embodiment, a positioning bracket is fixedly installed on the right side of the drive motor, and the rear end of the positioning bracket is bent, with the bent portion at the rear end connected to the right side of the sedimentation tank.

[0008] As a preferred embodiment, both sides of the bottom of the movable seat are provided with longitudinal sliding grooves, and the upper part of the movable rod extends into the interior of the sliding groove and is slidably connected.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model features a sliding movable seat on a support plate. The movable seat drives the sludge pipe to slide on the movable rod. Simultaneously, the support plate slides within the guide groove of the fixed seat via a guide slider. In conjunction with the drive motor, the threaded rod rotates, causing the threaded block to move and thus moving the support plate. This enables multi-directional movement of the sludge pipe within the sedimentation tank, allowing for targeted sludge removal from different areas of the sedimentation tank, improving the uniformity and efficiency of sludge removal. An air compression device introduces compressed air into the sludge pipe through pipes, air pipes, and branch pipes. Utilizing the air lift principle, the sludge at the bottom of the sedimentation tank is discharged. An air jet nozzle is located at the lower end of the sludge pipe, from which compressed air is ejected, further enhancing the sludge removal effect.

[0014] 2. This utility model provides a stable sliding track for the support plate through the combination of a fixed base, a guide groove, and a guide slider, ensuring smooth movement and reducing swaying. The transmission mechanism, consisting of a threaded rod, a threaded block, and a drive motor, converts the rotational motion of the drive motor into the linear motion of the threaded block, which in turn drives the guide slider and the support plate to move along the guide groove. This design achieves precise control of the sludge pipe position. Operators can flexibly adjust the position of the sludge pipe by controlling the drive motor according to the sludge distribution in the sedimentation tank, and perform targeted cleaning of sludge in different areas, significantly improving sludge discharge efficiency and effectiveness.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0021] Example 1:

[0022] Please see Figure 1 As shown, this utility model provides an upper air-lift sludge removal device for a sedimentation tank, including a sedimentation tank 1. A support plate 5 is provided above the sedimentation tank 1. A movable seat 6 is provided on the left side of the top of the support plate 5. Movable rods 7 are slidably installed on both sides of the bottom of the movable seat 6. The bottom of the movable rods 7 is fixedly installed to the top of the support plate 5. A sludge pipe 8 is sleeved inside the movable seat 6. The lower end of the sludge pipe 8 extends to the bottom of the inner cavity of the sedimentation tank 1, and the other end extends to the outside of the sedimentation tank 1. An air compressor 9 is fixedly installed on the right side of the top of the support plate 5. An air pipe 11 is connected to the front of the air compressor 9 through a pipe 10. The lower end of the air pipe 11 extends into the interior of the sedimentation tank 1 and is connected to the lower end of the sludge pipe 8 through a branch pipe 12.

[0023] This technical solution uses a sliding seat 6 on the support plate 5. The sliding seat 6 drives the sludge pipe 8 to slide on the moving rod 7. At the same time, the support plate 5 can slide in the guide groove 3 of the fixed seat 2 through the guide slider 4. In addition, the drive motor 16 drives the threaded rod 14 to rotate, which moves the threaded block 15 and thus drives the support plate 5 to move. This realizes the multi-directional movement of the sludge pipe 8 in the sedimentation tank 1, which can target the sludge discharge in different areas of the sedimentation tank 1, improving the uniformity and efficiency of sludge discharge. The air compression device 9 introduces compressed air into the sludge pipe 8 through the pipe 10, air pipe 11 and branch pipe 12. The sludge at the bottom of the sedimentation tank 1 is discharged by using the air lifting principle. The lower end of the sludge pipe 8 is equipped with an air jet port. The compressed air is sprayed out from the air jet port, which can better drive the sludge to rise and improve the sludge discharge effect.

[0024] Example 2:

[0025] Based on Embodiment 1, this utility model is as follows: Figure 2 As shown, a fixed base 2 is fixedly installed at both the upper and lower ends of the side of the sedimentation tank 1. A guide groove 3 is opened inside the fixed base 2. A guide slider 4 is slidably installed on the upper part of the guide groove 3. The top of the guide slider 4 is connected to the bottom of the end of the support plate 5. A positioning plate 13 is fixedly installed at the upper end of the left side of the front of the sedimentation tank 1. A threaded rod 14 is rotatably installed on the right side of the positioning plate 13. A threaded block 15 is installed on the external thread of the threaded rod 14. The top of the threaded block 15 is connected to the surface of the front guide slider 4. A drive motor 16 is fixedly installed at the right end of the threaded rod 14.

[0026] Adopting such Figure 1 The technical solution shown, with the combination of fixed base 2, guide groove 3 and guide slider 4, provides a stable sliding track for support plate 5, ensuring smooth movement and reducing swaying. The transmission mechanism consisting of threaded rod 14, threaded block 15 and drive motor 16 converts the rotational motion of drive motor 16 into the linear motion of threaded block 15, thereby driving guide slider 4 and support plate 5 to move along guide groove 3. This design achieves precise control of the position of sludge pipe 8. Operators can flexibly adjust the position of sludge pipe 8 by controlling drive motor 16 according to the sludge distribution in sedimentation tank 1, and carry out targeted cleaning of sludge in different areas, significantly improving sludge discharge efficiency and effect.

[0027] Secondly, in the technical solution, a positioning bracket 17 is fixedly installed on the right side of the drive motor 16. The rear end of the positioning bracket 17 is bent, and the bent part of the rear end is connected to the right side of the sedimentation tank 1. Both sides of the bottom of the movable seat 6 are provided with longitudinal sliding grooves, and the upper part of the movable rod 7 extends into the interior of the sliding groove and is slidably connected.

[0028] Its adoption is as follows Figure 1In the technical solution shown, the precise positioning of the drive motor 16 is the key to ensuring the stable rotation of the threaded rod 14 and the accurate movement of the threaded block 15. The positioning bracket 17 fixes the drive motor 16 so that its position will not shift during operation, ensuring that the threaded rod 14 and the threaded block 15 always maintain the correct meshing relationship. In this way, when the drive motor 16 drives the threaded rod 14 to rotate, the threaded block 15 can move smoothly along the predetermined trajectory, thereby accurately controlling the position of the support plate 5 and the sludge pipe 8, and improving the accuracy and efficiency of the sludge discharge operation.

[0029] Example 3:

[0030] This utility model is as follows Figures 1-3 As shown, an air jet is provided on the right side of the lower end of the sludge pipe 8, and the left end of the branch pipe 12 is connected to the air jet. The inner wall of the sludge pipe 8 is provided with an anti-adhesion coating made of polytetrafluoroethylene. A one-way valve is provided at the connection between the branch pipe 12 and the sludge pipe 8.

[0031] Using the above technical solution, the jet nozzle on the lower right side of the sludge pipe 8 is connected to the branch pipe 12, allowing the compressed air generated by the air compressor 9 to be precisely injected from the lower end of the sludge pipe 8. Compared with other injection methods, this design can create a stronger air lifting force at the bottom of the sludge pipe 8. By utilizing the buoyancy and propulsion of the rising air, the sludge at the bottom of the sedimentation tank 1 can be lifted and discharged more efficiently. Especially for densely deposited sludge, the strong air lifting force can effectively loosen and carry the sludge upward, significantly improving the sludge discharge efficiency. Polytetrafluoroethylene has an extremely low surface friction coefficient and excellent non-stickiness, making it difficult for sludge to adhere to the inner wall of the sludge pipe 8 coated with this coating. During the sludge discharge process, even if the sludge has a certain degree of stickiness or contains impurities, it can pass smoothly through the sludge pipe 8, greatly reducing the risk of sludge pipe 8 clogging. This not only ensures the continuity of sludge discharge but also reduces the time interrupted by cleaning blockages, improving the overall operating efficiency of the equipment.

[0032] The working principle of this utility model is as follows: After the air compressor 9 is started, compressed air is generated and transmitted to the branch pipe 12 through the pipe 10 and air pipe 11. Finally, it is injected from the jet nozzle on the right side of the lower end of the sludge pipe 8. The compressed air forms a group of bubbles in the sludge pipe 8. During the rising process of the bubbles, they use their own buoyancy and propulsion to drive the surrounding sludge to move upward together. Since the group of bubbles forms a strong air lifting force at the bottom of the sludge pipe 8, it can not only lift the sludge with good fluidity, but also effectively loosen and carry the denser sludge, realizing the process of sludge at the bottom of the sedimentation tank 1 moving to the top of the sludge pipe 8 and being discharged from the sedimentation tank 1. When the drive motor 16 is started, it drives the threaded rod 14 to rotate. The threaded block 15, due to the threaded engagement with the threaded rod 14, converts the rotational motion of the threaded rod 14 into linear motion, thereby driving the front guide slider 4 to move in the guide groove 3, so that the support plate 5 slides along the side of the sedimentation tank 1, thereby driving the sleeved sludge pipe 8 to move flexibly in the sedimentation tank 1 to meet the sludge discharge needs of different areas.
