Description

Technical Field

[0001] This utility model relates to the field of sedimentation tank technology, specifically a novel sedimentation tank. Background Technology

[0002] A sedimentation tank is a water treatment structure that uses gravity settling to separate suspended solids (SS) from water. It is one of the most basic, commonly used, and crucial physical treatment units in water and wastewater treatment. Currently, the sediments on the bottom surface of radial flow sedimentation tanks are loose and difficult to collect, resulting in low sludge removal efficiency.

[0003] To address the aforementioned issues, we propose a novel sedimentation tank. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a new type of sedimentation tank. In order to solve the above-mentioned technical problem, this utility model provides the following technical solution: This utility model discloses a new type of sedimentation tank, which includes a circular tank body with an inlet channel at the center. A water collection trough is fixed on the outer periphery of the tank body and is connected to a guide channel. The bottom of the tank body is provided with multiple concentrically arranged dirt-collecting baffles of different diameters. The cross-section of the dirt-collecting baffles is arc-shaped, and the inner arc surface of the dirt-collecting baffles faces the inlet channel. A bracket is fixed at the upper end of the inlet channel, and a cantilever is rotatably connected to the bracket. The rotation axis of the cantilever is coincident with the central axis of the inlet channel. A sludge scraping component and a sludge suction mechanism are provided on the cantilever.

[0005] Preferably, the suction mechanism includes a suction pump fixed on the cantilever and a plurality of suction pipes corresponding one-to-one with the dirt-collecting baffle rings. The lower end of the suction pipe is located at the lower end of the inner arc surface of the corresponding dirt-collecting baffle ring, and the upper ends of the plurality of suction pipes are all connected to a merging pipe, which is connected to the inlet end of the suction pump.

[0006] Preferably, a shaft frame is fixed on the cantilever, and a roller is rotatably connected to the shaft frame. The roller is connected to the output shaft of the suction pump through a bevel gear set.

[0007] Preferably, the annular upper surface of the pool is fixedly connected to the guide rail by multiple support rods, and the center of the guide rail is located on the rotation axis of the cantilever, with the rollers rolling along the surface of the guide rail.

[0008] Preferably, the groups are set up in a one-to-one correspondence with the pollution-collecting barrier rings.

[0009] Preferably, the sludge scraping assembly includes a rod slidably connected to the cantilever, a pressure plate fixed at the upper end of the rod, the pressure plate being connected to the cantilever via a spring, a bracket fixed at the lower end of the rod, and a scraper being detachably and fixedly connected to the bracket via fixing bolts. The scraper contacts the bottom surface of the pool body inside the corresponding sludge-collecting baffle ring, and a water passage hole is provided on the scraper.

[0010] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: by concentrically setting up various dirt-collecting baffle rings with different diameters, the sludge that settles to the bottom of the pool is dispersed on the inner arc surface of each dirt-collecting baffle ring, which further reduces the water flow velocity and allows the sludge to be carried to the inner arc surface of the dirt-collecting baffle ring, thus improving the settling efficiency. Then, the sludge is circulated and sucked out from the inner arc surface of each dirt-collecting baffle ring by the suction mechanism, improving the sewage discharge efficiency. Moreover, the sludge scraping component automatically scrapes the sludge on the bottom surface of the pool in real time, avoiding sludge deposition and realizing continuous sewage discharge.

[0013] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention. Example

[0014] like Figures 1 to 4As shown, the novel sedimentation tank includes a circular tank body 1, with an inlet channel 2 at the center of the tank body 1. A water collection trough 3 is fixed on the outer periphery of the tank body 1, and the water collection trough 3 is connected to a guide channel 16. Multiple concentrically arranged dirt-collecting baffle rings 4 with different diameters are provided at the bottom of the tank body 1. The cross-section of the dirt-collecting baffle ring 4 is arc-shaped, and the inner arc surface of the dirt-collecting baffle ring 4 faces the inlet channel 2. A bracket 5 is fixed at the upper end of the inlet channel 2, and a cantilever 6 is rotatably connected to the bracket 5. The rotation axis of the cantilever 6 coincides with the central axis of the inlet channel 2. A sludge scraping assembly and a sludge suction mechanism are provided on the cantilever 6.

[0015] In this embodiment, the suction mechanism includes a suction pump 11 fixed on the cantilever 6 and a plurality of suction pipes 10 corresponding one-to-one with the dirt-collecting baffle rings 4. The lower end of the suction pipe 10 is located at the lower end of the inner arc surface of the corresponding dirt-collecting baffle ring 4. The upper ends of the plurality of suction pipes 10 are all connected to a confluence pipe 9, and the confluence pipe 9 is connected to the inlet end of the suction pump 11. A shaft frame 17 is fixed on the cantilever 6, and a roller 18 is rotatably connected to the shaft frame 17. The roller 18 is connected to the output shaft of the suction pump 11 through a bevel gear set 19. The annular upper surface of the pool body 1 is fixedly connected to a guide rail 7 through a plurality of support rods 8. The center of the guide rail 7 is located on the rotation shaft of the cantilever 6, and the roller 18 rolls along the surface of the guide rail 7.

[0016] In this embodiment, multiple sets of sludge scraping assemblies are provided, and each set corresponds to a sludge-collecting baffle ring 4. The sludge scraping assembly includes a rod 12 slidably connected to the cantilever 6. A pressure plate 13 is fixed to the upper end of the rod 12. The pressure plate 13 is connected to the cantilever 6 through a spring 14. A bracket 15 is fixed to the lower end of the rod 12. A scraper 20 is detachably fixed to the bracket 15 through a fixing bolt 21. The scraper 20 contacts the bottom surface of the pool body 1 inside the corresponding sludge-collecting baffle ring 4, and a water passage hole 22 is opened on the scraper 20.

[0017] The principle and advantages of this utility model: In this novel sedimentation tank, sewage enters the tank body 1 through the inlet channel 2 and flows radially from the center to the edge of the tank, thereby slowing down the flow rate and causing suspended solids in the water to settle under gravity and gather at the inner arc surface of each sludge-collecting baffle ring 4 under the action of water flow. The sludge-collecting baffle rings 4 with different diameters disperse the weight of the settled sludge, which further reduces the water flow speed and allows the sludge to be carried to the inner arc surface of the sludge-collecting baffle ring 4, thus improving the sedimentation efficiency. The suction pump 11 is started to work, and the suction pump 11 extracts the sludge collected on the inner arc surface of each sludge-collecting baffle ring 4 through the confluence pipe 9 and each suction pipe 10. The output shaft of the suction pump 11 drives the roller 18 to move continuously on the guide rail 7 through the bevel gear set 19, thereby driving the cantilever 6 to rotate around the center of the guide rail 7, and thus causing the suction pipe 10 to circulate and extract the sludge from the inner arc surface of the corresponding sludge-collecting baffle ring 4, improving the sewage discharge efficiency.

[0018] As described above, while the cantilever 6 rotates, the scraper 20 driven by the boom 12 scrapes up the mud and sludge on the corresponding bottom surface of the pool and carries it to the inner arc surface of the corresponding sludge-collecting baffle ring 4 under the action of water flow, thereby playing the role of automatic mud scraping, avoiding sludge deposition, and realizing continuous sewage discharge.

[0019] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
