Abstract
Description
Technical Field
[0001] This utility model relates to the field of sedimentation tank technology, and in particular to a sedimentation tank for soil and water conservation with an auxiliary sludge scraping structure. Background Technology
[0002] Wastewater inevitably mixes with silt and sand during its migration, flow, and collection. If this sand is not removed beforehand through sedimentation and separation, it will affect the operation of subsequent treatment equipment. Most importantly, it can wear down pumps and machinery, clog pipe networks, and interfere with or even destroy biological treatment processes. Grit chambers are primarily used to remove sand particles larger than 0.2 mm in diameter and with a density greater than 2.65 t / m³ from wastewater, protecting pipes, valves, and other facilities from wear and blockage. Their working principle is based on gravity separation; therefore, the influent flow rate of the grit chamber should be controlled so that heavier inorganic particles settle, while organic suspended particles are carried away by the water flow.
[0003] Chinese Patent Publication No. CN 213077646 U discloses a high-efficiency sedimentation tank for soil and water conservation, including a sedimentation tank body. Water inlet pipes are fixedly connected to the center of both the left and right sides of the top of the sedimentation tank body. A first electric telescopic rod is embedded inside a limiting block. The output shaft of the first electric telescopic rod, near the center of the sedimentation tank body, passes through the inner wall of the sedimentation tank body and is fixedly connected to a fixing block. A second electric telescopic rod is embedded inside the fixing block near the center of the right side. A pusher plate is fixedly connected to the bottom of the output shaft of the second electric telescopic rod. A first leaking plate is fixedly connected between the left and right sides of the inner wall of the sedimentation tank body near the top, and a second leaking plate is fixedly connected between the left and right sides of the inner wall of the sedimentation tank body near the bottom. This invention enables the device to efficiently separate and remove silt from sewage, automatically clear blockages, and reduce the workload of workers.
[0004] The existing technical solutions have the following shortcomings: Although the technical solutions can automatically clear blockages during use, impurities tend to accumulate on top during the entry of muddy water, which slows down the water intake speed and reduces the overall separation effect. There is room for optimization. Therefore, it is necessary to design a water and soil conservation sedimentation tank with an auxiliary sludge scraping structure to solve the problems mentioned above. Utility Model Content
[0005] The purpose of this invention is to provide a sedimentation tank for soil and water conservation with an auxiliary sludge scraping structure, so as to solve the problem of poor silt-water separation effect mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a soil and water conservation sedimentation tank with an auxiliary sludge scraping structure, comprising a fixing frame and a sedimentation tank body, wherein the fixing frame is fixed to the top of one side of the sedimentation tank body;
[0007] A first extension block and a second extension block are fixed to both ends of one side of the fixed frame, respectively. A first electric push rod is fixed to one side of the first extension block, and a second electric push rod is fixed to one side of the second extension block. A third electric push rod is fixed to one side of the fixed frame below the second extension block. A first separation plate, a second separation plate, and a third separation plate are sequentially connected to one side of the interior of the grit chamber. The output end of the first electric push rod is connected to the first separation plate, the output end of the second electric push rod is connected to the second separation plate, and the output end of the third electric push rod is connected to the third separation plate. A first separation net is installed inside the first separation plate, a second separation net is installed inside the second separation plate, and a third separation net is installed inside the third separation plate. Scrapers are fixed to the bottom of one side of each of the first, second, and third separation plates. Inlet pipes and outlet pipes are fixed to both sides of the grit chamber. Three sets of sludge discharge pipes are installed at the bottom of one side of the grit chamber.
[0008] Preferably, slide rails are fixed on both sides of the main body of the sedimentation tank, and mounting blocks are fixed on both sides of the first separation plate, the second separation plate and the third separation plate, and limit blocks are connected to the outer side of the mounting blocks, and the limit blocks are slidably connected to the outer side of the slide rails.
[0009] Preferably, a mounting plate is fixed to the inner side of the limiting block, and a positioning block is fixed to the inner side of the mounting plate. The mounting block has a positioning groove inside, and the positioning groove is connected to the positioning block.
[0010] Preferably, mounting posts are uniformly fixed on one side of the mounting block, and threaded heads are fixed on the outer side of each mounting post. Mounting holes are uniformly arranged inside the mounting plate, and the mounting holes are connected to the mounting posts. Threaded caps are threadedly connected to the outer side of each threaded head.

[0012] Preferably, the size of each mounting post is matched with the size of the mounting hole, and four sets of mounting posts and mounting holes are provided.
[0013] Preferably, the scraper has an arc-shaped cross-section, and there are three sets of scrapers.
[0014] Compared with the prior art, the beneficial effects of this utility model are: the soil and water conservation sedimentation tank with auxiliary sludge scraping structure realizes the function of easy separation and cleaning;
[0015] During operation, three sets of separation plates are positioned on the left side of the grit chamber. When sludge and water are injected into the grit chamber through the inlet pipe, the first electric push rod is activated, moving the first separation plate to the right. The first separation net blocks larger impurities at the far right of the grit chamber. Subsequently, the second and third electric push rods are activated sequentially, moving the second and third separation plates to the right. These plates further separate the sludge and impurities through separation nets of different aperture sizes. During this separation process, the water flows continuously, preventing clogging of the separation nets. When all three sets of separation plates have moved to the right, the clear water on the left flows out through the outlet pipe. During this outflow, due to the drop in water level and the obstruction of the separation nets, the water at the separation nets is simultaneously separated into clear water flowing towards the outlet pipe. Meanwhile, the sludge is pushed to the right by scrapers as the separation plates move and discharged through the sludge discharge pipe. The operation is simple and convenient, allowing for simultaneous sludge scraping and cleaning of the grit chamber without clogging the separation process, thus improving practicality and flexibility.

[0024] Please see Figures 1-5 The present invention provides the following technical solution:
[0025] Example 1
[0026] To address the issues of poor filtration and cleaning performance in existing technologies, the following solution is disclosed, specifically as follows: Figure 1 , Figure 2 and Figure 3As shown, the soil and water conservation sedimentation tank with auxiliary sludge scraping structure provided in this application includes a fixing frame 1 and a sedimentation tank body 11. The fixing frame 1 is fixed to the top of one side of the sedimentation tank body 11. A first extension block 2 and a second extension block 3 are fixed to both ends of one side of the fixing frame 1, respectively. A first electric push rod 4 is fixed to one side of the first extension block 2, and a second electric push rod 7 is fixed to one side of the second extension block 3. A third electric push rod 8 is fixed to one side of the fixing frame 1 below the second extension block 3. A first separation plate 5, a second separation plate 6, and a third separation plate 9 are sequentially connected to one side inside the sedimentation tank body 11. The output end of the first electric push rod 4 is connected to the first separation plate 5. The output end of the second electric push rod 7 is connected to the second separation plate 6, and the output end of the third electric push rod 8 is connected to the third separation plate 9. The first separation plate 5 is equipped with a first separation net 17, the second separation plate 6 is equipped with a second separation net 19, and the third separation plate 9 is equipped with a third separation net 20. Scrapers 18 are fixed to the bottom of one side of the first separation plate 5, the second separation plate 6, and the third separation plate 9. The cross-section of the scrapers 18 is arc-shaped, and there are three sets of scrapers 18. The two sides of the main body 11 of the sedimentation tank are respectively fixed with inlet pipe 15 and outlet pipe 16. Three sets of sludge discharge pipes 13 are set to the bottom of one side of the main body 11 of the sedimentation tank.
[0027] In this embodiment, during use, silt and water are injected into the main body 11 of the sedimentation tank through the inlet pipe 15. The first electric push rod 4 is activated to move the first separation plate 5 to the right. The larger impurities are blocked at the far right of the main body 11 of the sedimentation tank by the first separation net 17. Subsequently, the second electric push rod 7 and the third electric push rod 8 are activated in sequence, which move the second separation plate 6 and the third separation plate 9 to the right in sequence. The silt and impurities are further blocked and separated by the separation net with different aperture sizes. During the separation process, the water flow is in a flowing state. The separation net can separate silt and sand without causing blockage. When all three sets of separation plates have moved to the right, the water on the left is the clear water after separation and flows out through the outlet pipe 16. During the outflow process, due to the drop in water level and the obstruction of the separation net, the water at the separation net is simultaneously separated into clear water and flows to the outlet pipe 16. The silt is concentrated and pushed to the right by the scraper 18 when the separation plates move and is discharged through the sludge discharge pipe 13.
[0028] Example 2
[0029] This embodiment differs from Embodiment 1 in that it incorporates a loading and unloading structure to facilitate component maintenance. Specifically, as shown below... Figure 1 , Figure 4 and Figure 5As shown, slide rails 10 are fixed on both sides of the main body 11 of the sedimentation tank. Mounting blocks 14 are fixed on both sides of the first separation plate 5, the second separation plate 6, and the third separation plate 9. Limiting blocks 12 are connected to the outer sides of each mounting block 14. The limiting blocks 12 are slidably connected to the outer sides of the slide rails 10. Mounting plates 21 are fixed to the inner sides of the limiting blocks 12, and positioning blocks 23 are fixed to the inner sides of the mounting plates 21. Positioning grooves 26 are provided inside the mounting blocks 14, and the positioning grooves 26 are connected to the positioning blocks 23. Mounting posts 24 are evenly fixed on one side of mounting plate 14, and threaded heads 25 are fixed on the outer side of each mounting post 24. Mounting holes 22 are evenly arranged inside mounting plate 21, and the mounting holes 22 are connected to mounting posts 24. Threaded caps 28 are threadedly connected to the outer side of each threaded head 25. A gasket 27 is connected to one side of the threaded cap 28, and the inner side of the gasket 27 is in contact with mounting plate 21. The size of each mounting post 24 matches the size of each mounting hole 22. There are four sets of mounting posts 24 and mounting holes 22.
[0030] In this embodiment, during use, the threaded cap 28 is rotated to connect or separate it from the threaded head 25, thereby fixing or unfixing the mounting column 24. This facilitates the connection or disconnection between the mounting block 14 and the limiting block 12. In other words, after the electric push rod separates from the separation plate, it is convenient to maintain the separation plate to ensure the use of the 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.
