Description

Technical Field

[0001] This utility model relates to the field of sludge cleaning technology for sewage treatment, specifically a sludge cleaning device for the biological treatment tank of a sewage treatment plant. Background Technology

[0002] As is well known, biological treatment tanks are a crucial component of wastewater treatment plants. Through a series of biochemical reactions, these tanks remove organic matter and other pollutants from wastewater. However, during long-term operation, a large amount of sludge inevitably accumulates inside the biological treatment tank. This sludge not only occupies the effective volume of the tank but can also affect treatment efficiency and even damage the equipment. Traditional sludge cleaning methods rely primarily on manual labor, including physical removal using simple tools such as shovels and rakes. This method is not only labor-intensive and inefficient but also poses a threat to worker health and safety due to the complex environment and confined space within the biological treatment tank. Some wastewater treatment plants have attempted to use mechanical equipment for sludge cleaning, but most existing equipment has significant limitations. For example, some equipment can only operate in a fixed position and cannot be flexibly moved to different areas of the biological treatment tank; others, while movable, are not flexible enough in adjusting angles and directions, making it difficult to effectively cover all areas requiring cleaning, especially corners and sidewalls. For the reasons mentioned above, traditional sludge cleaning methods often fail to completely remove all sludge from biological treatment tanks, especially stubborn sludge adhering to the inner walls, which is usually difficult to clean thoroughly. This results in residual sludge continuing to affect treatment efficiency and, over time, may increase maintenance costs and the risk of equipment failure. Therefore, it is necessary to propose a solution to this technical problem. Utility Model Content

[0022] 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.

[0023] Please see Figure 1-4This utility model relates to a sludge cleaning device for a biological treatment tank in a sewage treatment plant. It includes a lifting mechanism 1 and a suction pump 2. The lifting mechanism 1 has a displacement mechanism at its top. The suction pump 2 has a suction pipe 3 and a discharge pipe 4. The bottom end of the suction pipe 3 has a drainage pipe 5. The inner wall of the drainage pipe 5 has a sealing groove, and a bearing seat 6 is provided on the sealing groove. A drainage ring 7 is provided between the bearing seat 6 and the inner wall of the drainage pipe 5. A drainage plate 8 is provided on the inner wall of the drainage ring 7. A toothed ring 9 is provided between the drainage ring 7 and the sealing groove. A drive box 10 is provided on one side of the drainage pipe 5. A drive motor 11 is located inside the drive box 10. A drive gear 12 is provided at the output end of the drive motor 11. The drive gear 12 meshes with the gear ring 9. The output end of the lifting mechanism 1 is provided with a first adjusting box 13, and a second adjusting box 14 is provided below the first adjusting box 13. A first bearing 15 and a first motor 16 are provided between the first adjusting box 13 and the second adjusting box 14. A second bearing 17 and a second motor 18 are provided between one side of the second adjusting box 14 and the drive box 10. In this embodiment, the lifting mechanism 1 is installed on a displacement mechanism. The displacement mechanism can be any device capable of moving the lifting mechanism 1. The lifting mechanism 1 moves the device to the biological treatment tank of the sewage treatment plant, and then the output end of the lifting mechanism 1 is controlled to extend and move, thereby moving the drainage pipe 5 of the suction pipe 3 to the sewage. On the sludge in the biological treatment tank of the treatment plant, the output of the first motor 16 of the first regulating box 13 drives the second regulating box 14 to rotate, thereby adjusting the angle position of the drainage pipe 5 on one side of the first regulating box 13. The first bearing 15 can improve the rotational stability of the second regulating box 14. By controlling the output of the second motor 18 in the second regulating box 14 to rotate the drive box 10, the tilt angle of the drainage pipe 5 on the drive box 10 can be adjusted, which facilitates the suction operation of the sludge on the side. By turning on the suction pump 2, the sludge can be sucked in through the drainage pipe 5 on the suction pipe 3. The sludge passes through the suction pipe 3 and the suction pump, and is finally discharged from the discharge pipe 4. By controlling the drive motor inside the drive box 10... The output end of the drive motor 11 rotates the drive gear 12, which in turn drives the gear ring 9 to rotate by an angle. The gear ring 9 then drives the guide ring 7 to rotate by an angle. Through the bearing seat 6, the guide ring 7 can rotate stably on the inner wall of the sewage pipe 4. The guide plate 8 on the guide ring 7 can scrape the sludge remaining on the inner wall of the biological treatment tank of the sewage treatment plant and enter the suction pipe 3 for suction and discharge operations. This can achieve efficient automatic cleaning of the sludge on the inner wall of the biological treatment tank of the sewage treatment plant. It is easy to use. The guide ring 7 is attached to the inner wall of the guide pipe 5 to block the sealing groove, and the guide ring 7 and the sealing groove are sealed using existing technologies, such as the use of sealing rings, which will not be described in detail in this structure. This will prevent sludge from entering the sealing groove.

[0024] In this scheme, the displacement mechanism includes a transverse slide rail 19 and a longitudinal slide rail 20. A transverse electric slider 21 is provided on the transverse slide rail 19 and is installed at the top of the lifting mechanism 1. A longitudinal electric slider 22 is provided on the longitudinal slide rail 20. A connecting frame 23 is provided between the longitudinal electric slider 22 and the transverse slide rail 19. By using the transverse electric slider 21 to drive the lifting mechanism 1 to move on the transverse slide rail 19, the transverse position of the drainage pipe 5 in the biological treatment tank of the sewage treatment plant can be adjusted. By controlling the longitudinal electric slider 22 to move on the longitudinal slide rail 20, the longitudinal electric slider 22 drives the transverse slide rail 19 to move through the connecting frame 23, thereby adjusting the longitudinal position of the drainage pipe 5 in the biological treatment tank of the sewage treatment plant.

[0025] In this solution, there are two symmetrically arranged connecting brackets 23, which can better support the transverse slide rail 19.

[0026] In this design, the bearing housing 6, the first bearing 15, and the second bearing 17 are all sealed bearings. Sealed bearings can further improve the sealing performance and reduce the entry of sewage.

[0027] In this solution, the drive motor 11, the first motor 16, and the second motor 18 are all servo motors. Servo motors have the characteristic of high rotational accuracy, which can improve the control accuracy during use.

[0028] In this solution, the lifting mechanism 1 is a hydraulic rod, which has the characteristics of high moving accuracy and good stability, thus enabling stable and reliable lifting and moving of the drainage pipe 5.

[0029] In this solution, the diversion plates 8 are arranged in a ring array, and the multiple diversion plates 8 arranged in a ring array can more efficiently scrape off the dirt remaining on the inner wall of the biological tank of the sewage treatment plant.

[0030] In this solution, the suction pipe 3 is made of TPU material. TPU material combines high strength and excellent flexibility, and also has good tear resistance and wear resistance. It can be used in scenarios where the angle of the drainage pipe 5 needs to be adjusted frequently, thereby improving the service life of the suction pipe 3 when used in this structure.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
