Description

Technical Field

[0001] This utility model belongs to the technical field of sewage treatment equipment, and in particular relates to a high-pressure flushing device for a triangular weir used in the effluent of a secondary sedimentation tank. Background Technology

[0002] The triangular weir at the effluent of the secondary sedimentation tank is a key component of the wastewater treatment secondary sedimentation tank. It is triangular in shape and its main function is to uniformly collect the supernatant after treatment in the secondary sedimentation tank and allow it to flow out. The structural design of the triangular weir allows the water to pass through the weir opening at a relatively stable and uniform speed. This uniformity helps to improve the quality of the effluent and avoids uneven mud and water entrainment caused by local water flow that is too fast or too slow. The size and spacing of the weir opening are precisely calculated and can be adjusted according to factors such as the size of the secondary sedimentation tank and the amount of water to be treated, so as to ensure that the effluent from the secondary sedimentation tank can enter the subsequent treatment process or discharge stage efficiently and stably.

[0003] Currently, floating sludge occurs in the inlet channel of the secondary sedimentation tank during operation, which not only affects the normal progress of the sewage treatment process but also reduces treatment efficiency. This results in excessive algae growth on the effluent triangular weir, which in severe cases affects the effluent water quality. Significant manpower and resources are required annually for manual flushing, which is time-consuming and labor-intensive. Furthermore, the flushing operation is carried out in a specific environment, posing significant safety hazards. Therefore, we have developed a high-pressure flushing device for the effluent triangular weir of the secondary sedimentation tank to solve the aforementioned problems. Utility Model Content

[0004] The purpose of this invention is to provide a high-pressure flushing device for the triangular weir at the outlet of a secondary sedimentation tank. By adjusting the components and cleaning components, the problem of excessive green algae on the triangular weir at the outlet of the existing secondary sedimentation tank, which seriously affects the quality of the effluent, is solved.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0006] This utility model relates to a high-pressure flushing device for a triangular weir at the effluent of a secondary sedimentation tank. It includes a sedimentation tank, inside which a drive platform is installed. A water tank is located on one side of the drive platform, and a pressurized water pump is connected to the top of the water tank. A water outlet on one side of the pressurized water pump is connected to a water supply pipe. An adjustment assembly is located on one side of the drive platform, comprising a drive housing located on one side of the water tank, a transmission wheel movably connected inside the drive housing, a synchronous belt fitted onto the surface of the transmission wheel, and a movable frame installed at the bottom of the synchronous belt. A cleaning assembly is located on one side of the drive housing, comprising a high-pressure nozzle connected to the other end of the water supply pipe and a cleaning brush installed at the bottom of the movable frame.

[0007] The present invention is further configured such that the adjustment component includes a drive motor installed on one side of the drive housing, an auxiliary roller installed inside the drive housing, and the output end of the drive motor passes through the drive housing and is fixedly connected to the transmission wheel.

[0008] The present invention is further configured such that a sludge scraping arm is installed on one side of the drive platform, a mounting plate is provided on one side of the sludge scraping arm, one side of the mounting plate is fixedly connected to the drive housing, and the bottom of the water tank is fixedly connected to the mounting plate.

[0009] The present invention is further configured such that a fixing screw is provided through one side of the mounting plate, and a nut is threaded onto the surface of the fixing screw.

[0010] The present invention is further configured such that a spring rope is installed at the top of the water supply pipe, and the water supply pipe is made of corrugated hose material.

[0011] The present invention is further configured such that a sliding plate is fixedly connected to the surface of the movable frame, and a limiting plate is fixedly connected to one side of the sliding plate.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model achieves efficient cleaning of the triangular weir at the effluent of the secondary sedimentation tank through the synergistic effect of the adjustment component and the cleaning component. The synchronous belt pulls the moving frame to move along the path of the drive housing, allowing the high-pressure nozzle to tilt and adjust its angle. Combined with the corrugated hose water pipe, it flexibly adapts to different rinsing needs, significantly improving cleaning coverage and efficiency. At the same time, the cleaning brush moves synchronously with the moving frame, which can promptly remove impurities remaining after the nozzle rinsing, avoid secondary deposition, ensure the long-term cleanliness of the triangular weir surface, reduce the frequency of manual intervention, and lower safety risks.

[0016] 2. This device integrates sludge cleaning and triangular weir cleaning functions through the linkage design of the drive platform and the sludge scraper arm. When the sludge scraper arm rotates, it drives the mounting plate and water tank to move synchronously, so that the high-pressure flushing device can cover the entire triangular weir area. The structure of the fixing screw and nut enhances the installation stability, the sliding plate and limit plate constrain the trajectory of the moving frame to avoid deviation, and the support wheel optimizes the smoothness of the synchronous belt drive, ensuring that the cleaning brush and high-pressure nozzle work together. This solves the problems of low efficiency, high cost and safety hazards of traditional manual flushing.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] 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 skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1 Please see Figures 1-5This utility model is a high-pressure flushing device for a triangular weir at the effluent of a secondary sedimentation tank. It includes a sedimentation tank 1, a drive platform 2 installed inside the sedimentation tank 1, a water tank 3 on one side of the drive platform 2, a pressurized water pump 4 connected to the top of the water tank 3, and a water supply pipe 5 connected to the outlet of the pressurized water pump 4. An adjustment component 6 is provided on one side of the drive platform 2. The adjustment component 6 includes a drive housing 601 located on one side of the water tank 3, a transmission wheel 602 movably connected inside the drive housing 601, a synchronous belt 603 sleeved on the surface of the transmission wheel 602, and a movable frame 604 installed at the bottom of the synchronous belt 603. A cleaning component 7 is provided on one side of the drive housing 601. The cleaning component 7 includes a high-pressure nozzle 701 connected to the other end of the water supply pipe 5 and a cleaning brush 702 installed at the bottom of the movable frame 604.

[0027] Specifically, the water tank 3 stores the mixed cleaning solution. When the pressurized water pump 4 is working, the motor drives the impeller to rotate at high speed, causing the cleaning solution in the water tank 3 to be drawn into the pressurized water pump 4 under the action of centrifugal force. As the impeller continues to rotate, the cleaning solution is continuously compressed and pressurized. The pressurized cleaning solution is transported to the high-pressure nozzle 701 through the water pipe 5. The high-pressure nozzle 701 has a pressurized flow channel design inside, and the cleaning solution is sprayed out from the nozzle at high speed to form a high-pressure water flow to complete the cleaning work. The synchronous belt 603 conveys on the surface of the transmission wheel 602 and the auxiliary roller 704, driving the moving frame 604 to move along the path of the drive housing 601. The cleaning brush 702 can contact the surface of the triangular weir and clean the impurities on the surface of the triangular weir during the movement. Specific Implementation Example 2 Please see Figures 1-5 Based on the first specific embodiment, the adjustment component 6 also includes a drive motor 703 installed on one side of the drive housing 601, an auxiliary roller 704 installed inside the drive housing 601, the output end of the drive motor 703 passing through the drive housing 601 and fixedly connected to the transmission wheel 602, a sludge scraping arm 8 installed on one side of the drive platform 2, an installation plate 9 provided on one side of the sludge scraping arm 8, one side of the installation plate 9 fixedly connected to the drive housing 601, the bottom of the water tank 3 fixedly connected to the installation plate 9, a fixing screw 10 passing through one side of the installation plate 9, a nut 11 threadedly connected to the surface of the fixing screw 10, a spring rope 12 installed on the top of the water supply pipe 5, the water supply pipe 5 being made of corrugated hose, a slide plate 13 fixedly connected to the surface of the moving frame 604, a limit plate fixedly connected to one side of the slide plate 13, a support wheel 14 provided inside the synchronous belt 603, one side of the support wheel 14 being movably connected to the inner wall of the drive housing 601 via a bearing, a fixing block 15 fixedly connected to one side of the high-pressure nozzle 701, and the other side of the fixing block 15 fixedly connected to the moving frame 604.

[0029] Specifically, the drive platform 2 in the sedimentation tank 1 is driven by a power source such as a motor. When the motor is running, it transmits power to the rotating shaft of the scraper arm 8 through a transmission device such as a reducer. The rotating shaft starts to rotate under the power drive, thereby driving the scraper arm 8 to make a circular motion around the center of the sedimentation tank 1, scraping the sludge settled at the bottom of the tank towards the sludge collection pit, thus realizing the collection of sludge. This is a mature existing technology application. This device is fixed to one side of the scraper arm 8 by the mounting plate 9 and the fixing screw 10. With the power of the drive platform 2, it realizes the circular motion. The spring rope 12 can pull the water pipe 5 to prevent the water pipe 5 from falling down. The top of the slide plate 13 is slidably connected to the surface of the drive shell 601, which can improve the stability of the moving frame 604 when it moves.

[0030] The operation process of this embodiment is as follows: When it is necessary to clean the triangular weir of the sedimentation tank 1, the staff starts the pressurized water pump 4, the pressurized water pump 4 draws out the cleaning liquid inside the water tank 3, and sprays the cleaning liquid out through the water pipe 5 and the high-pressure nozzle 701 to wash away the impurities on the surface of the triangular weir. Then the drive platform 2 is started, the drive platform 2 drives the sludge scraping arm 8 to rotate, the sludge scraping arm 8 drives the drive housing 601 and the high-pressure nozzle 701 to rotate, covering the entire triangular weir, which can improve the cleaning effect.

[0031] Simultaneously, the drive motor 703 can be started, which drives the transmission wheel 602 to rotate. The transmission wheel 602, in conjunction with the synchronous belt 603, adjusts the position of the moving frame 604, allowing the high-pressure nozzle 701 to tilt and flush the triangular weir from different angles. As the moving frame 604 moves, it can also drive the cleaning brush 702 to move. The cleaning brush 702 removes the impurities after flushing, further improving the cleaning effect. The entire cleaning process does not require manual assistance, which can effectively improve cleaning efficiency and safety.
