Description

Technical Field

[0002] A sewage treatment sand settling device is a device designed to remove sand and other heavy particles from sewage and is widely used in municipal and industrial sewage treatment plants. Through the physical separation process, this device can effectively reduce the wear and clogging problems in the sewage treatment process and improve the efficiency and effectiveness of subsequent treatment steps.

[0003] In the existing technology, firstly, it becomes difficult to control the water level of some devices, and it is difficult to flexibly adjust the water level according to the treatment needs. The drainage channel cannot be flexibly opened or closed, which affects the drainage efficiency of the sedimentation tank, which may cause the water flow to stagnate during the treatment process, reduce the sewage treatment efficiency, and hinder continuous discharge, which may cause the treatment process to be interrupted, affecting the operating efficiency of the entire sewage treatment system. Secondly, the water injection port of some devices cannot ensure the unidirectional flow of water, which may cause the treated water to mix with the untreated water, affecting the quality and efficiency of sewage treatment. Under certain operating conditions, such as equipment shutdown or water pressure changes, backflow is likely to occur, increasing the risk of secondary pollution. Finally, some devices cause sediment accumulation, affecting the smooth flow of water and the efficiency of sewage treatment, which may cause the water flow during the treatment process to be difficult to control, affecting the overall treatment efficiency and effect.

[0030] See also Figure 1-5A sewage treatment sedimentation device comprises a sedimentation tank 1, a tank cover 2, a lateral drainage mechanism, a directional anti-reverse mechanism and a spiral auxiliary mechanism. The directional anti-reverse mechanism comprises a circulation pipe 3, a push plate 4, a connecting rod 5, a truncated cone block 6, an inner plate 7 and a circular hole 8. The inner plate 7 is installed in the circulation pipe 3, and the circular hole 8 is arranged on the inner plate 7. The push plate 4 is movably installed in the circulation pipe 3. The connecting rod 5 is installed at one end of the push plate 4. The truncated cone block 6 is installed at one end of the connecting rod 5, and the truncated cone block 6 is movably extended into and pulled out of the circular hole 8. The spiral auxiliary mechanism comprises a rotating pipe 9, a spiral pipe 10, a limiting plate 11, a movable pipe 12 and a square hole 13. The rotating pipe 9 is movably arranged on the outer wall of the circulation pipe 3. The spiral pipe 10 is connected to the rotating pipe 9, and the inner wall of the spiral pipe 10 is connected to the outer wall of the movable pipe 12. The limiting plate 11 is arranged on the inner wall of the spiral pipe 10. The limiting plate 11 limits the moving range of the movable pipe 12. A plurality of groups of square holes 13 are arranged on the side of the movable pipe 12.

[0031] In this embodiment, when the sewage discharge equipment is discharged into the device, this device is used to ensure that the water flow can only flow in one direction. The internal plate 7 is installed inside the flow pipe 3, the circular hole 8 is set on the internal plate 7, and the push plate 4 is movably installed inside the flow pipe 3. When the water flow direction is correct, the water flows downward through the push plate 4 and the connected truncated cone block 6. The truncated cone block 6 is set to be thin at the top and thick at the bottom, so the water flow is easy to flow from the thin part to the thick part, thereby facilitating the water flow. If the water tries to flow back, the water flows from the thick part to the reverse part, making the resistance of the truncated cone block 6 in the circular hole 8 larger, effectively preventing the water from flowing in the opposite direction, thereby ensuring the correctness of the water flow direction and preventing backflow. The rotating tube 9 is movably set around the outer wall of the flow pipe 3 , connected to the spiral tube 10, and a limit plate 11 is arranged in the spiral tube 10 to limit the moving range of the movable tube 12. During use, as the rotating tube 9 rotates, the design of the spiral tube 10 will drive the movable tube 12 to move along the rotation direction. This movement can be used to adjust the water flow in the circulation tube 3, or assist in removing the sediment in the circulation tube 3. Multiple groups of square holes 13 are arranged on the side of the movable tube 12, which can be adjusted as needed to control the water flow or promote the cleaning process, and the spiral tube 10 will push the movable tube 12 to move upward and downward, so as to facilitate the movement of the push plate 4 connected to the movable tube 12, thereby assisting the operation of the directional anti-reversal mechanism.

[0032] The lateral drainage mechanism includes a lateral drainage box 14, a telescopic cylinder 15, a movable plate 16, a sealing plate 17 and a drainage groove 18. The drainage groove 18 is arranged on the side wall of the sedimentation tank. The lateral drainage box 14 is arranged on the side of the sedimentation tank. The telescopic cylinder 15 is arranged on the side of the lateral drainage box 14. The other end of the telescopic cylinder 15 extends into the box and is connected to the movable plate 16. The sealing plate 17 is arranged on the side of the movable plate 16, and the sealing plate 17 can be moved on the drainage groove 18 to seal the side of the sedimentation tank 1.

[0033] When the lateral drainage mechanism needs to be operated, after the sewage in the sedimentation tank 1 is left to settle, the sludge sinks to the bottom, and then the water is discharged from the side of the sedimentation tank 1. During operation, the telescopic cylinder 15 drives the movable plate 16 to move forward and backward. When the telescopic cylinder 15 contracts, the movable plate 16 moves backward, so that the blocking plate 17 is away from the drainage groove 18, thereby opening the side leading to the sedimentation tank so that water can flow out through the drainage groove 18. When it is necessary to stop drainage or when the sedimentation tank needs to be closed, the telescopic cylinder 15 will expand and push the movable plate 16 forward, causing the blocking plate 17 to cover the drainage groove 18 and prevent water from flowing out, thereby achieving the purpose of controlling the water level in the sedimentation tank.

[0034] See also Figure 1-5 As a supplementary implementation of a sewage treatment sedimentation device for the lateral drainage mechanism, the directional anti-reverse mechanism and the spiral auxiliary mechanism: a connecting pipe 19 is fixedly provided on the top of the tank cover 2, and one end of the flow pipe 3 is fixedly connected to the connecting pipe 19, a water injection pipe 20 is provided on one side of the rotating pipe 9, and the water injection pipe 20 is movably sealed with the rotating pipe 9, a mounting block 21 is provided on the top of the movable plate 16, lateral rods 22 are provided on both sides of the mounting block 21, and a roller 23 is provided at one end of the lateral rod 22, and wheel grooves 24 are provided on both sides of the top of the drainage box, and the rollers 23 can be embedded in the wheel grooves 24. An internal matching guide connection is provided, a water collecting box 25 is provided at the bottom of the side drainage box 14, and a filter screen 26 is provided at the bottom of the drainage box and the top of the water collecting box 25, and the bottom end face of the sealing plate 17 is in contact with the filter screen 26, a limiting rail 27 is provided at the top of the rotating tube 9, a limiting groove 28 is provided at the bottom of the water injection pipe 20, and the limiting rail 27 can be embedded in the limiting groove 28 for a matching guide connection, a sewage pipe 29 is provided at the bottom of the sedimentation tank 1, and a sealing cover 30 is provided on the sewage pipe 29, a supporting leg 31 is provided at the bottom of the sedimentation tank 1, and a drainage pipe 32 is provided on the side of the water collecting box 25.

[0035] More specifically, the connecting pipe 19 fixed on the tank cover 2, the water injection pipe 20 on one side of the rotating tube 9 and its movable sealing design with the rotating tube 9 facilitate the introduction of sewage into the treatment system while maintaining the closedness of the system and reducing the spread of odor and pollutants. The mounting block 21, lateral rod 22 and roller 23 and corresponding wheel groove 24 design on the top of the extension plate simplify the mechanical complexity of the drainage box operation and improve the operational stability and maintenance convenience of the equipment. The water collecting box 25 and filter screen 26 design at the bottom of the drainage box not only facilitate the collection and preliminary filtration of sewage, but also reduce the risk of solid waste blocking the drainage system.

[0036] In summary, when the overall equipment is in use or operating: when the lateral drainage mechanism needs to be operated, after the sewage in the sedimentation tank 1 is left to settle, the sludge sinks to the bottom, and then the water is discharged from the side of the sedimentation tank 1. During operation, the telescopic cylinder 15 drives the movable plate 16 to move forward and backward. When the telescopic cylinder 15 contracts, the movable plate 16 moves backward, so that the sealing plate 17 is away from the drainage groove 18, thereby opening the side leading to the sedimentation tank so that water can flow out through the drainage groove 18. When the drainage needs to be stopped or when the sedimentation tank needs to be closed, the telescopic cylinder 15 will expand and push the movable plate 16 forward, causing the sealing plate 17 to cover the drainage groove 18 and prevent water from flowing out, thereby achieving the purpose of controlling the water level in the sedimentation tank.

[0037] When the directional anti-reverse mechanism needs to be operated and the sewage equipment is discharged into the device, this device is used to ensure that the water can only flow in one direction. The internal plate 7 is installed inside the circulation pipe 3, and the circular hole 8 is set on the internal plate 7. The push plate 4 is movably installed inside the circulation pipe 3. When the water flow direction is correct, the water flows downward through the push plate 4 and the connected truncated cone block 6. The truncated cone block 6 is set to be thin at the top and thick at the bottom, so the water flow is easy to flow from the thin part to the thick part, thereby facilitating the water flow to pass through. If the water tries to flow back, the water flows from the thick part to the reverse part, making the resistance of the truncated cone block 6 in the circular hole 8 larger, effectively preventing the water from flowing in the opposite direction, thereby ensuring the correctness of the water flow direction and preventing backflow.

[0038] When the operation of the spiral auxiliary mechanism is required, the rotating tube 9 is movably arranged around the outer wall of the circulation tube 3 and is connected to the spiral tube 10, and a limit plate 11 is arranged in the spiral tube 10 to limit the movement range of the movable tube 12. During use, as the rotating tube 9 rotates, the design of the spiral tube 10 will drive the movable tube 12 to move along the rotation direction. This movement can be used to adjust the water flow in the circulation tube 3, or assist in removing the sediment in the circulation tube 3. Multiple groups of square holes 13 are arranged on the side of the movable tube 12, which can be adjusted as needed to control the water flow or promote the cleaning process, and the spiral tube 10 will push the movable tube 12 to move upward and downward, so as to facilitate the movement of the push plate 4 connected to the movable tube 12, thereby assisting the operation of the directional anti-reverse mechanism.

[0039] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described here one by one. In the above, all fixed connections are preferably welded. Although the embodiments of the utility model have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the utility model.
