Description

Technical Field

[0001] This utility model belongs to the field of sludge treatment technology, and in particular relates to a sedimentation tank for sludge treatment. Background Technology

[0002] Sedimentation tanks are structures that remove suspended solids from water using sedimentation. They are water purification devices that utilize the natural sedimentation or coagulation sedimentation of water to remove suspended solids. Sedimentation tanks are classified into horizontal sedimentation tanks and vertical sedimentation tanks according to the direction of water flow. The sedimentation effect depends on the water flow rate and the residence time of the water in the sedimentation tank. In order to improve the sedimentation effect and reduce the land area required, honeycomb inclined tube countercurrent sedimentation tanks, accelerated clarification tanks, pulse clarification tanks, etc. are currently widely used. Sedimentation tanks are widely used in wastewater treatment.

[0003] Existing sedimentation tanks for sludge treatment cannot effectively and quickly settle the sludge due to the varying flow rates and concentrations of sludge in the water. Furthermore, the flow direction of the water in the tank cannot be adjusted in real time, making it extremely prone to short-circuiting or floc breakage caused by the impact of incoming water. Therefore, we propose a new sedimentation tank for sludge treatment. Utility Model Content

[0004] The purpose of this invention is to provide a sedimentation tank for sludge treatment to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides a sedimentation tank for sludge treatment, comprising:

[0006] A cylindrical body, wherein a mounting plate is provided on the top surface of the cylindrical body, and a mounting column is rotatably mounted on the inner bottom surface of the cylindrical body. A rotating shaft is fixedly mounted on the top end of the mounting column, and the top end of the rotating shaft is fixedly connected to the bottom surface of the mounting plate. An mounting groove is provided on the inner bottom surface of the mounting column.

[0007] A cylindrical plate is disposed on the outer side wall of the mounting column, and the inner side wall of the cylindrical plate is slidably connected to the outer side wall of the mounting column. An opening groove is provided on one side of the cylinder, and a cylindrical valve is rotatably installed in the opening groove.

[0008] A drive assembly, which is disposed in the mounting slot and is used to drive the mounting column to rotate;

[0009] An adjustment component is disposed within an opening slot and is used to adjust the rotation of the cylindrical valve.

[0010] In the above technical solution, the driving component further includes a first toothed ring, which is fixedly installed at the bottom end of the mounting column. A second toothed ring is fixedly installed on the inner side wall of the cylindrical plate, and the second toothed ring meshes with the first toothed ring. A drive motor is fixedly installed on the inner top surface of the cylinder, and the top end of the output shaft of the drive motor is fixedly connected to the inner top surface of the mounting groove.

[0011] In this technical solution, the drive motor starts, and its output shaft drives the mounting column to rotate. Since the mounting column is connected to the mounting groove, it drives the mounting column to rotate. The first toothed ring at the bottom of the mounting column rotates accordingly, and the second toothed ring that meshes with the first toothed ring is driven, so that the cylindrical plate slides and rotates on the outer wall of the mounting column. This structure can effectively improve the sludge sedimentation efficiency and avoid sludge adhesion affecting the sedimentation effect.

[0012] In the above technical solution, the adjusting component further includes a gear, which is fixedly installed at the bottom end of the cylindrical valve. The bottom end of the gear is rotatably connected to the inner bottom surface of the opening groove. An electric push rod is fixedly installed on one side of the inner bottom surface of the opening groove. A rack is fixedly installed at one end of the electric push rod. The bottom surface of the rack is slidably connected to the inner bottom surface of the opening groove, and the rack meshes with the gear.

[0013] In this technical solution, the electric push rod starts working, pushing the rack to slide on the bottom surface inside the opening slot. Since the rack meshes with the gear, the movement of the rack drives the gear to rotate, thereby causing the cylindrical valve fixed at the top of the gear to rotate inside the opening slot. By controlling the extension and retraction length of the electric push rod, the rotation angle of the cylindrical valve is adjusted, and the opening degree of the opening slot is precisely controlled, thereby controlling the discharge volume and discharge speed of sludge, realizing flexible adjustment of the sludge discharge process, and meeting the sludge treatment needs under different working conditions.

[0014] In the above technical solution, two scrapers are fixedly installed on the outer wall of the cylindrical plate, and the outer walls of the two scrapers are in contact with the inner wall of the cylinder.

[0015] In this technical solution, as the cylindrical plate rotates, the scraper continuously scrapes off the sludge adhering to the inner wall of the cylinder, causing it to settle to the bottom of the cylinder, thereby improving the sludge sedimentation efficiency and preventing sludge adhesion from affecting the sedimentation effect.

[0016] In the above technical solution, rollers are fixedly installed on both sides of the bottom surface of the mounting plate, and a sliding groove is opened on the top surface of the cylinder, with both rollers slidably installed in the sliding groove.

[0017] In this technical solution, workers can stand on the mounting plate, which rotates with the mounting column, allowing them to observe the sedimentation of sludge inside the cylinder in real time. It is simple and practical.

[0018] In the above technical solution, a first protective railing is further fixedly installed on the top surface of the cylinder.

[0019] This technical solution prevents workers from accidentally falling into the cylinder from the outside; it is simple and practical.

[0020] Furthermore, in the above technical solution, a second protective railing is fixedly installed on both sides of the top surface of the mounting plate.

[0021] This technical solution prevents workers from accidentally falling into the cylinder while standing on the mounting plate, and is simple and practical.

[0022] The beneficial effects of this utility model are:

[0023] 1. This sludge treatment sedimentation tank, when put into operation, starts the drive motor, and its output shaft drives the mounting column to rotate. Since the mounting column is connected to the mounting groove, it rotates, causing the first toothed ring at the bottom of the mounting column to rotate. The second toothed ring, which meshes with the first toothed ring, is also driven, causing the cylindrical plate to slide and rotate on the outer wall of the mounting column. The scraper on the outer wall of the cylindrical plate is in close contact with the inner wall of the cylinder. As the cylindrical plate rotates, the scraper continuously scrapes off the sludge adhering to the inner wall of the cylinder, causing it to settle to the bottom of the cylinder, improving the sludge sedimentation efficiency and preventing sludge adhesion from affecting the sedimentation effect. This structure can also effectively change the flow direction of the water in the tank, avoiding the problems of short flow or floc breakage caused by the impact of incoming water. It is simple and practical.

[0024] 2. In this sludge treatment sedimentation tank, when the settled sludge needs to be discharged, the electric push rod starts working, pushing the rack to slide on the bottom surface inside the opening slot. Since the rack meshes with the gear, the movement of the rack drives the gear to rotate, thereby causing the column valve fixed at the top of the gear to rotate inside the opening slot. By controlling the extension and retraction length of the electric push rod, the rotation angle of the column valve is adjusted, and the opening degree of the opening slot is precisely controlled, thereby controlling the discharge volume and discharge speed of sludge. This allows for flexible adjustment of the sludge discharge process, meeting the sludge treatment needs under different working conditions. Workers can also observe the sedimentation status of the sludge in the tank and control the opening and closing of the column valve to release excess water, effectively allowing the sludge in the tank to settle quickly and efficiently.

[0038] Example 1:

[0039] Please see Figure 1-6 As shown in the figure, this embodiment provides a sedimentation tank for sludge treatment.

[0040] include:

[0041] The cylinder 1 has a mounting plate 3 on its top surface and a mounting column 9 rotatably mounted on its inner bottom surface. A rotating shaft 5 is fixedly mounted on the top of the mounting column 9 and is fixedly connected to the bottom surface of the mounting plate 3. A mounting groove 10 is formed on the inner bottom surface of the mounting column 9. A cylindrical plate 12 is disposed on the outer wall of the mounting column 9, and its inner wall is slidably connected to the outer wall of the mounting column 9. An opening groove 15 is formed on one side of the cylinder 1, and a cylindrical valve 16 is rotatably mounted within the opening groove 15. A driving assembly is disposed within the mounting groove 10 and is used to drive the mounting column 9 to rotate. An adjusting assembly is disposed within the opening groove 15 and is used to adjust the rotation of the cylindrical valve 16. When it is necessary to discharge the settled sludge, the electric push rod 19 starts to work, pushing the rack 17 to slide on the bottom surface inside the opening groove 15. Since the rack 17 meshes with the gear 18, the movement of the rack 17 drives the gear 18 to rotate, thereby causing the column valve 16 fixed at the top of the gear 18 to rotate inside the opening groove 15. By controlling the extension and retraction length of the electric push rod 19, the rotation angle of the column valve 16 is adjusted, and the opening degree of the opening groove 15 is precisely controlled, thereby controlling the discharge volume and discharge speed of sludge. This allows for flexible adjustment of the sludge discharge process, meeting the sludge treatment needs under different working conditions. Workers can also observe the sedimentation status of the sludge in the pool and control the opening and closing of the column valve 16 to release excess water, effectively allowing the sludge in the pool to settle quickly and effectively.

[0043] This embodiment provides a sedimentation tank for sludge treatment, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0044] The drive assembly includes a first toothed ring 13, which is fixedly installed at the bottom of the mounting column 9. A second toothed ring 14 is fixedly installed on the inner side wall of the cylindrical plate 12, and the second toothed ring 14 meshes with the first toothed ring 13. A drive motor 11 is fixedly installed on the inner top surface of the cylinder 1. The top end of the output shaft of the drive motor 11 is fixedly connected to the inner top surface of the mounting groove 10. When the drive motor 11 is started, its output shaft drives the mounting column 9 to rotate. Since the mounting column 9 is connected to the mounting groove 10, it drives the mounting column 9 to rotate. The first toothed ring 13 at the bottom of the mounting column 9 rotates accordingly, and the second toothed ring 14, which meshes with the first toothed ring 13, is driven, so that the cylindrical plate 12 slides and rotates on the outer side wall of the mounting column 9. This structure can effectively improve the sludge sedimentation efficiency and avoid sludge adhesion affecting the sedimentation effect.

[0047] The adjusting component includes a gear 18, which is fixedly installed at the bottom of a cylindrical valve 16. The bottom of the gear 18 is rotatably connected to the inner bottom surface of an opening groove 15. An electric push rod 19 is fixedly installed on one side of the inner bottom surface of the opening groove 15. A rack 17 is fixedly installed at one end of the electric push rod 19. The bottom surface of the rack 17 is slidably connected to the inner bottom surface of the opening groove 15. The rack 17 meshes with the gear 18. When the electric push rod 19 starts working, it pushes the rack 17 to slide on the inner bottom surface of the opening groove 15. Because the rack 17 meshes with the gear 18, the movement of the rack 17 drives the gear 18 to rotate, thereby causing the cylindrical valve 16 fixed at the top of the gear 18 to rotate within the opening groove 15. By controlling the extension and retraction length of the electric push rod 19, the rotation angle of the cylindrical valve 16 is adjusted, and the opening degree of the opening groove 15 is precisely controlled, thereby controlling the discharge volume and discharge speed of sludge. This achieves flexible adjustment of the sludge discharge process and meets the sludge treatment needs under different working conditions.

[0060] In use: When the sludge treatment sedimentation tank is put into operation, the drive motor 11 starts, and its output shaft drives the mounting column 9 to rotate. Since the mounting column 9 is connected to the mounting groove 10, the mounting column 9 rotates, and the first toothed ring 13 at the bottom of the mounting column 9 rotates accordingly. The second toothed ring 14, which meshes with the first toothed ring 13, is driven, causing the cylindrical plate 12 to slide and rotate on the outer wall of the mounting column 9. The scraper 8 on the outer wall of the cylindrical plate 12 is in close contact with the inner wall of the cylinder 1. As the cylindrical plate 12 rotates, the scraper 8 continuously scrapes off the sludge attached to the inner wall of the cylinder 1, causing it to settle to the bottom of the cylinder 1, improving the sludge sedimentation efficiency and avoiding sludge adhesion that affects the sedimentation effect. This structure can also effectively change the flow direction of the water in the tank, avoiding the problem of short flow or floc breakage caused by the impact of incoming water. It is simple and practical.

[0061] When it is necessary to discharge the settled sludge, the electric push rod 19 starts to work, pushing the rack 17 to slide on the bottom surface inside the opening slot 15. Since the rack 17 meshes with the gear 18, the movement of the rack 17 drives the gear 18 to rotate, thereby causing the column valve 16 fixed at the top of the gear 18 to rotate inside the opening slot 15. By controlling the extension and retraction length of the electric push rod 19, the rotation angle of the column valve 16 is adjusted, and the opening degree of the opening slot 15 is precisely controlled, thereby controlling the discharge volume and discharge speed of the sludge. This allows for flexible adjustment of the sludge discharge process, meeting the sludge treatment needs under different working conditions. Workers can also observe the sedimentation status of the sludge in the pool and control the opening and closing of the column valve 16 to release excess water, effectively allowing the sludge in the pool to settle quickly and efficiently.
