Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically an automatic cleaning device for the effluent weir of a radial flow sedimentation tank. Background Technology

[0002] In wastewater treatment systems, radial flow sedimentation tanks are often used as primary and secondary sedimentation tanks. Wastewater contains a large amount of organic matter, and a large amount of moss will grow on the effluent weir under sunlight. Suspended solids in the wastewater will also settle at the bottom of the effluent weir, which not only affects the appearance, but also causes the moss to fall off and the sludge at the bottom of the weir to decompose, which will also have an adverse effect on subsequent treatment processes. At present, it can only be cleaned manually on a regular basis, which is not only labor-intensive, but also poses safety risks such as being squeezed by sludge scrapers and drowning during cleaning.

[0003] In summary, there is an urgent need for a device that can automatically clean the outlet weir to reduce the labor intensity of workers and prevent safety accidents. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides an automatic cleaning device for the effluent weir of a radial flow sedimentation tank. This device solves the problem that a large amount of moss will grow on the effluent weir under sunlight, and suspended solids in the sewage will also settle at the bottom of the effluent weir. Currently, the only solution is to clean it manually on a regular basis, which is not only labor-intensive, but also poses safety risks such as being squeezed by a sludge scraper and drowning during cleaning.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic cleaning device for the effluent weir of a radial flow sedimentation tank, comprising an auxiliary flow sedimentation tank, wherein a support column is fixedly installed at the center of the inner wall of the auxiliary flow sedimentation tank, a bridge frame is rotatably connected to the top of the support column, a hanging connecting rod is fixedly installed below the end of the bridge frame away from the support column, a hanging support rod is fixedly connected below the hanging connecting rod, and cleaning mechanisms are provided below and on both sides of the hanging support rod, the cleaning mechanism comprising an outer sleeve rod, the outer sleeve rod being fixedly connected to the outer wall of the hanging support rod, an inner sliding rod being slidably connected to the inner wall of the outer sleeve rod, the inner sliding rod passing through the end of the outer sleeve rod, and columns being fixedly connected to the opposite inner walls of the inner sliding rod and the outer sleeve rod, with compression springs sleeved on the two columns, and a scraper being fixedly installed at the end of the outer sleeve rod by bolts.

[0006] As a further embodiment of this utility model: one side of the mounting support rod is rotatably connected to a connecting shaft above the cleaning mechanism, and a cleaning brush is fixedly installed at the end of the connecting shaft by bolts.

[0007] As a further embodiment of this utility model: a weir plate is fixedly installed between the inner walls of the auxiliary flow sedimentation tank near its top, and an outlet weir is provided inside the weir plate.

[0008] As a further embodiment of this utility model: the cleaning mechanism is located inside the water outlet weir, the scraper at the bottom of the hanging support rod is the same width as the water outlet weir, the scrapers on both sides are the same height as the water outlet weir, and the cleaning brush is the same height as the weir plate and fits against the top of the weir plate.

[0009] As a further embodiment of this utility model: a connecting frame is fixedly installed below the bridge frame, and a squeegee is fixedly connected below the connecting frame. The squeegee is designed with an inclination and fits against the inner bottom of the auxiliary flow sedimentation tank.

[0010] As a further embodiment of this utility model: a support wheel is installed at the end of the bridge frame on one side of the hanging connecting rod, and the support wheel is attached to the top of the auxiliary flow sedimentation tank.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This automatic cleaning device for the effluent weir of the radial sedimentation tank, through the setting of a cleaning mechanism, when using the device, the rotation of the bridge frame drives the cleaning mechanism to move along the effluent weir. The clamping spring in the cleaning mechanism is inside the outer sleeve rod and the inner slide rod, providing a certain pressure to the inner slide rod, allowing the inner slide rod to slide and extend within the outer sleeve rod. This causes the inner slide rod to drive the scraper to fit tightly against the inner wall of the effluent weir, maintaining close contact with the effluent weir. When the scraper encounters dirt or sludge on the effluent weir, the clamping spring ensures that the scraper has sufficient force to remove it. In this way, the cleaning mechanism can automatically fit against the effluent weir and effectively remove dirt and sludge, reducing the labor intensity of workers, ensuring the cleaning effect of the effluent weir, and ensuring the stability of water quality.

[0012] 2. This automatic cleaning device for the effluent weir of the radial flow sedimentation tank, through the setting of a connecting shaft and a cleaning brush, allows the bridge to rotate during use. The cleaning brush is connected to the hanging support rod via the connecting shaft and moves with the hanging support rod. Due to the precise matching of the height and position of the cleaning brush with the weir plate, the cleaning brush can effectively scrub the surface of the weir plate, removing dirt and moss attached to the weir plate, enabling comprehensive cleaning of the weir plate, further improving the cleaning effect of the entire effluent weir area, enhancing the overall performance of the device, and ensuring the smooth flow of the effluent weir and the cleanliness of the water quality.

Detailed Implementation

[0014] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0015] like Figure 1-5 As shown, this utility model provides a technical solution: an automatic cleaning device for the effluent weir of a radial flow sedimentation tank, including an auxiliary flow sedimentation tank 1. A support column 2 is fixedly installed at the center of the inner wall of the auxiliary flow sedimentation tank 1. A bridge frame 3 is rotatably connected to the top of the support column 2. The rotatable connection of the bridge frame 3 realizes the automated operation of the cleaning mechanism 6. The bridge frame 3 is driven to rotate by a power source, eliminating the need for manual operation of the bridge frame 3, greatly improving work efficiency, ensuring the continuity and stability of the cleaning process, and enabling cleaning operations to be performed according to a set trajectory and speed, thereby ensuring the cleaning effect of the effluent weir 10. A connecting frame 11 is fixedly installed below the bridge frame 3. A squeegee 12 is fixedly connected to the auxiliary flow sedimentation tank 1. The squeegee 12 is designed to be inclined and fits against the bottom of the auxiliary flow sedimentation tank 1. A support wheel 13 is installed at the end of the bridge frame 3 on one side of the hanging connecting rod 4. The support wheel 13 fits against the top of the auxiliary flow sedimentation tank 1. Because of the support wheel 13, the support wheel 13 effectively supports the bridge frame 3 during the rotation process, so that it remains stable during the rotation process. This prevents the bridge frame 3 from shaking or tilting due to its own weight or the torque generated by the rotation. This ensures that the hanging connecting rod 4, the hanging support rod 5 and the cleaning mechanism 6 can move and work stably, improves the reliability and safety of the device operation, and ensures the smooth progress of the cleaning process. A hanging rod 4 is fixedly installed below the end of the cable tray 3 furthest from the support column 2. A hanging support rod 5 is fixedly connected below the hanging rod 4. Cleaning mechanisms 6 are provided below and on both sides of the hanging support rod 5. The cleaning mechanism 6 includes an outer rod 601, which is fixedly connected to the outer wall of the hanging support rod 5. An inner sliding rod 602 is slidably connected to the inner wall of the outer rod 601, and the inner sliding rod 602 passes through the end of the outer rod 601. Columns 603 are fixedly connected to the inner walls of the inner sliding rod 602 and the outer rod 601, respectively. A compression spring 604 is sleeved on both columns 603. Due to the presence of the compression spring 604, the elasticity of the compression spring 604... The inner sliding rod 602 can slide inside the outer rod 601, thereby allowing the scraper 605 to fit tightly against the surface of the outlet weir 10, effectively scraping away dirt and sludge on the outlet weir 10 and ensuring cleaning effect. The scraper 605 is fixedly installed at the end of the outer rod 601 by bolts. Because of the cleaning mechanism 6, the rotation of the bridge frame 3 drives the cleaning mechanism 6 to move along the direction of the outlet weir 10. The scraper 605 in the cleaning mechanism 6 moves along the inner wall of the outlet weir 10 to perform a comprehensive and uniform cleaning of the outlet weir 10, avoiding the missed areas that may occur during manual cleaning. This not only reduces the labor intensity of workers, but also improves the coverage and quality of cleaning. A connecting shaft 7 is rotatably connected to one side of the mounting support rod 5 above the cleaning mechanism 6. A cleaning brush 8 is fixedly installed at the end of the connecting shaft 7 by bolts. Through the cooperation between the connecting shaft 7 and the cleaning brush 8, the cleaning brush 8 can effectively scrub the surface of the weir plate 9 during the rotation of the bridge frame 3, removing the dirt and moss attached to the weir plate 9, and further improving the cleaning effect of the entire effluent weir 10 area. The weir plate 9 is fixedly installed near its top between the inner walls of the auxiliary flow sedimentation tank 1. The effluent weir 10 is opened inside the weir plate 9. The cleaning mechanism 6 is located inside the effluent weir 10. The scraper 605 at the bottom of the mounting support rod 5 is the same width as the effluent weir 10, and the scrapers 605 on both sides are the same height as the effluent weir 10. The cleaning brush 8 is the same height as the weir plate 9 and is attached to the top of the weir plate 9.

[0016] The working principle of this utility model is as follows: When using this device, the power source drives the bridge frame 3 to rotate around the center of the support column 2. The support wheel 13 is attached to the top of the auxiliary flow sedimentation tank 1 to support the bridge frame 3 and assist the bridge frame 3 to move smoothly. At this time, the hanging connecting rod 4 moves with the rotation of the bridge frame 3, thereby driving the hanging support rod 5 and the cleaning mechanism 6 below it to move along the direction of the outlet weir 10. The outer rod 601 and the inner sliding rod 602 in the cleaning mechanism 6 cooperate with each other. The compression spring 604 is inside the outer rod 601 and the inner sliding rod 602, providing a certain pressure to the inner sliding rod 602, so that the inner sliding rod 602 can slide and extend inside the outer rod 601, thereby causing the inner sliding rod 602 to drive the scraper 605 to fit tightly against the outlet weir 10. The scraper 605 maintains close contact with the effluent weir 10. When the scraper 605 encounters dirt or sludge on the effluent weir 10, the compression spring 604 ensures that the scraper 605 has sufficient force to scrape it off. At the same time, the cleaning brush 8 moves with the hanging support rod 5. Since its height is the same as that of the weir plate 9 and it is attached to the top of the weir plate 9, the cleaning brush 8 can scrub the surface of the weir plate 9 when the device moves, removing dirt and moss attached to the weir plate 9. Meanwhile, the smear plate 12 below the bridge frame 3 gathers the sludge at the bottom of the sedimentation tank towards the center. During long-term operation, if wear is found on the scraper 605 or the cleaning brush 8, the corresponding bolts can be removed to replace the scraper 605 clamp or the cleaning brush 8, thereby ensuring the cleaning effect of the device.
