Description

Technical Field

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

[0002] With the acceleration of urbanization and the continuous expansion of industrial production, the demand for sewage treatment is increasing. In the sewage treatment process, sedimentation tanks, as important treatment units, undertake the key task of removing suspended solids and large particulate matter from sewage. However, existing sedimentation tanks have some shortcomings in practical applications, especially in the regulation of sewage injection flow. In sewage treatment plants, the sewage flow fluctuates greatly at different times, and it is necessary to flexibly adjust the sewage injection flow according to actual needs to ensure the treatment effect and efficiency of the sedimentation tank. However, existing sedimentation tanks often lack effective flow regulation methods, resulting in poor treatment effect during high flow periods and waste of treatment resources during low flow periods.

[0003] In the wastewater treatment process, the settled clear water needs to be discharged from the sedimentation tank for further treatment or discharge. However, existing sedimentation tanks often cannot adjust the discharge height according to actual needs. For example, in some cases, it is necessary to discharge clear water to different treatment units or storage tanks, but existing sedimentation tanks can usually only discharge at a fixed height and cannot be flexibly adjusted. This fixed-height discharge method not only limits the flexibility of the treatment process, but may also lead to waste of clear water or a decrease in treatment effect. Utility Model Content

[0008] The present invention is further configured such that the height of the top surface of the baffle is lower than the height of the inlet box.

[0009] The present invention is further configured such that a sewage pipe is installed at the bottom end of the inclined cone bucket. This design effectively concentrates the sludge, facilitating the discharge and treatment of the sludge.

[0010] The present invention is further configured such that the outer sides of the multiple sets of flow control plates are provided with rounded corners. The rounded corner design reduces the resistance of water flow, making the flow control plate 15 smoother during the adjustment process and improving the adjustment efficiency and stability of the flow control mechanism.

[0011] The present invention is further configured such that a limiting block is provided on the outer side of the support ring, and multiple sets of the limiting block are provided; a limiting groove is provided on the inner wall of the adjusting sleeve, and multiple sets of the limiting groove are provided and are slidably connected to multiple sets of the limiting block respectively; the design of the limiting block and the limiting groove ensures that the flow control plate 15 will not shift during the adjustment process, thereby improving the stability and accuracy of the flow control mechanism and ensuring the precise control of sewage flow.

[0012] The present invention is further configured such that each of the multiple sets of flow control plates is provided with a compression spring, and the bottom end of each of the multiple sets of compression springs is fixedly connected to the top surface of the support ring. The design of the compression spring ensures that the flow control plate 15 can work stably during the adjustment process, avoids the position change of the flow control plate 15 caused by water flow pressure, and improves the reliability and stability of the flow control mechanism.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides a wastewater treatment sedimentation tank, which has the following beneficial effects:

[0017] 1. The sedimentation mechanism, through its unique design, significantly improves the treatment effect and efficiency of wastewater. The height of the baffle entering the tank is lower than the height of the tank itself, which allows for initial sedimentation of the wastewater upon entry. This slows down the rate at which wastewater enters and reduces the risk of large particles directly impacting the sedimentation tank. Wastewater must be higher than the baffle in the first half of the tank before flowing into the other half. This design further promotes the initial sedimentation of large particles. After a period of sedimentation, large particles in the wastewater gradually settle to the bottom of the inclined cone hopper and are discharged through the drain pipe. The upper layer of clear water is discharged through the drain hopper, which is installed on one side of the outer shell and has a drain pipe at its bottom for discharging the treated clear water from the sedimentation tank. This design not only improves the sedimentation effect but also ensures that the treated clear water can be discharged efficiently, reducing sludge accumulation and extending the service life of the sedimentation tank.

[0018] 2. The flow control mechanism achieves precise control of the sewage injection flow rate through its fine adjustment mechanism. When it is necessary to adjust the sewage injection flow rate, an adjustable flow space is formed between multiple sets of flow control plates. The preset force of the compression spring is set to be greater than the water flow pressure at the factory to ensure that the flow control plate can work stably during the adjustment process. This design allows operators to flexibly adjust the sewage injection flow rate according to actual needs, avoiding the problems of poor treatment effect during high flow periods and resource waste during low flow periods, thus improving the efficiency and flexibility of sewage treatment.

[0019] 3. The regulating mechanism, through its precise control mechanism, enables flexible adjustment of the discharge height of the settled water. By moving the movable plate, the position of the diversion box can be adjusted, thereby changing the water flow path in the drainage hopper. The position adjustment of the diversion box can adapt to different treatment needs, ensuring that the treated clean water can be discharged evenly. This design not only improves the flexibility of drainage, but also ensures that the treated clean water can be discharged to different treatment units or storage tanks according to actual needs, thereby improving the adaptability and efficiency of the entire sewage treatment system.

[0029] Please see Figures 1-5 A wastewater treatment sedimentation tank includes a support frame 1, on which a sedimentation mechanism is mounted. The sedimentation mechanism includes a shell 2, an inlet box 3, a baffle 4, an inlet pipe 5, an inclined cone hopper 6, a drain hopper 7, and a drain pipe 8. The shell 2 is mounted on the support frame 1. The inlet box 3 is mounted on the top of the shell 2. The baffle 4 is installed inside the inlet box 3. The inlet pipe 5 is installed on the bottom surface of the inlet box 3. The inclined cone hopper 6 is installed at the bottom end of the shell 2. The drain hopper 7 is installed on one side of the shell 2. The drain pipe 8 is installed at the bottom end of the drain hopper 7. A flow control mechanism is provided at the bottom end of the inlet pipe 5. The flow control mechanism includes an adjusting sleeve 9, a control sleeve 10, a connecting sleeve 11, a screw 12, a support block 13, and a support... The components include a strut 14, a flow control plate 15, a transmission sleeve 16, a support ring 17, and a top block 18. An adjusting sleeve 9 is installed at the bottom end of the inlet pipe 5. A control sleeve 10 is rotatably installed at the bottom end of the adjusting sleeve 9. A connecting sleeve 11 is installed inside the control sleeve 10. A screw 12 is installed on the top surface of the connecting sleeve 11. A support block 13 is rotatably installed on the top end of the screw 12. Multiple sets of support rods 14 are provided, with both ends connected to the support block 13 and the inner wall of the adjusting sleeve 9, respectively. The flow control plate 15 is rotatably installed on multiple sets of support rods 14. The transmission sleeve 16 is threadedly connected to the screw 12. The support ring 17 is installed on the outside of the transmission sleeve 16. Multiple sets of top blocks 18 are installed on the top surface of the support ring 17.

[0030] The top surface of baffle 4 is lower than the height of the inlet tank 3. When sewage enters the inlet tank 3, the sewage needs to be higher than baffle 4 in one half of the inlet tank 3 before it can flow into the other half. This design allows the sewage to undergo preliminary sedimentation in the inlet tank 3.

[0031] A drain pipe 19 is installed at the bottom of the inclined cone 6. The design of the inclined cone 6 allows the settled sludge to be concentrated at its bottom and discharged through the drain pipe 19.

[0032] The outer sides of the multiple flow control plates 15 are all rounded. The rounded corner design reduces the friction between the flow control plates 15 and the water flow, thus reducing the resistance of the water flow.

[0033] The support ring 17 is provided with a limiting block 20 on the outside. There are multiple sets of limiting blocks 20. The inner wall of the adjusting sleeve 9 is provided with a limiting groove 21. There are multiple sets of limiting grooves 21, which are slidably connected to multiple sets of limiting blocks 20 respectively. The design of the limiting block 20 and the limiting groove 21 ensures that the support ring 17 will not shift during movement, thus maintaining the stability and accuracy of the flow control plate 15.

[0034] Each of the multiple flow control plates 15 is equipped with a compression spring 22, and the bottom end of each of the multiple compression springs 22 is fixedly connected to the top surface of the support ring 17. When the flow control plate 15 rotates, the compression spring 22 provides a preset elastic force to ensure that the flow control plate 15 can work stably during the adjustment process.

[0035] In this embodiment, wastewater is injected into the inlet tank 3, located on one side of the baffle 4 of the inlet pipe 5. The baffle 4 slows down the speed at which the wastewater enters. The wastewater needs to rise above the baffle 4 in one half of the inlet tank 3 before flowing into the other half. The wastewater undergoes initial sedimentation in the inlet tank 3, reducing the direct impact of large particles on the sedimentation tank. After initial sedimentation by the baffle 4, the wastewater enters the outer shell 2 through the inlet pipe 5. The internal structure of the outer shell 2 allows for uniform distribution of the wastewater upon entry, further promoting the sedimentation of large particles. The inclined cone hopper 6 is installed at the bottom of the outer shell 2, and a drain pipe 19 is installed at its bottom for discharging the settled sludge. After a period of sedimentation, large particles in the wastewater gradually settle to the bottom of the inclined cone hopper 6 and are discharged through the drain pipe 19. The sewage pipe 19 discharges, while the upper layer of clean water is discharged through the drain hopper 7. The drain hopper 7 is installed on one side of the outer casing 2, and a drain pipe 8 is installed at its bottom end to discharge the treated clean water into the sedimentation tank. When it is necessary to adjust the injection flow rate of sewage, the rotating control sleeve 10 drives the screw 12 to rotate through the connecting sleeve 11. The screw 12 rotates and engages with the transmission sleeve 16 through a threaded connection, thereby driving the support ring 17 to move through the transmission sleeve 16. The support ring 17 pushes multiple sets of top blocks 18 to move upward. The top of the top block 18 abuts against the flow control plate 15, causing the flow control plate 15 to rotate along the support rod 14. At the same time, one side of the flow control plate 15 compresses the compression spring 22. An adjustable flow space is formed between the multiple sets of flow control plates 15. The preset force of the compression spring 22 is set to be greater than the water flow pressure at the factory.

[0036] Please see Figures 1-3As one implementation of the adjustment mechanism: The drainage hopper 7 is provided with an adjustment mechanism, which includes a mounting frame 23, a through groove 24, a moving plate 25, a motor 26, a lead screw 27, a transmission block 28, a drainage box 29, and a trough 30. The mounting frame 23 is installed inside the drainage hopper 7, the through groove 24 is provided on the mounting frame 23, the moving plate 25 is connected to one side of the mounting frame 23, the motor 26 is installed on the top surface of the mounting frame 23, the lead screw 27 is rotatably installed on the mounting frame 23 and connected to the output end of the motor 26, the transmission block 28 is installed on the moving plate 25 and threadedly connected to the lead screw 27, the drainage box 29 is installed on the moving plate 25, and multiple sets of troughs 30 are provided on the outside of the drainage box 29.

[0037] The mounting bracket 23 is equipped with guide rails 31. There are two sets of guide rails 31, which are slidably connected to the movable plate 25. The design of the guide rails 31 ensures that the movable plate 25 remains stable during sliding and prevents the movable plate 25 from shifting during movement.

[0038] More specifically, after the motor 26 starts, the rotation of the lead screw 27 drives the transmission block 28 to move. The transmission block 28 is mounted on the moving plate 25, thereby causing the moving plate 25 to slide on the mounting frame 23. The guide rail 31 is mounted on the mounting frame 23 to ensure that the moving plate 25 remains stable during the sliding process. By moving the moving plate 25, the position of the diversion box 29 can be adjusted, thereby changing the water flow path in the drainage hopper 7. The water flows into the diversion box 29 through the trough 30, and then flows into the drainage hopper 7 through the through groove 24, realizing precise control of the drainage height. The position adjustment of the diversion box 29 can adapt to different treatment needs, ensuring that the treated clean water can be discharged evenly.

[0039] In summary, during the use or operation of the overall equipment: wastewater is injected into the inlet tank 3, located on one side of the baffle 4 of the inlet pipe 5. The baffle 4 slows down the flow of wastewater. The wastewater needs to rise above the baffle 4 in one half of the inlet tank 3 before flowing into the other half. The wastewater undergoes initial sedimentation in the inlet tank 3, reducing the direct impact of large particles on the sedimentation tank. After initial sedimentation by the baffle 4, the wastewater enters the outer shell 2 through the inlet pipe 5. The internal structure of the outer shell 2 ensures that the wastewater is evenly distributed after entering, further promoting the sedimentation of large particles. The inclined cone hopper 6 is installed at the bottom of the outer shell 2, and a drain pipe 19 is installed at its bottom to discharge the settled sludge. After a period of sedimentation, large particles in the wastewater gradually settle to the bottom of the inclined cone hopper 6. The wastewater is discharged through the sewage pipe 19, while the upper layer of clean water is discharged through the drainage hopper 7. The drainage hopper 7 is installed on one side of the outer shell 2, and a drainage pipe 8 is installed at its bottom end to discharge the treated clean water into the sedimentation tank. When it is necessary to adjust the injection flow rate of the wastewater, the rotating control sleeve 10 drives the screw 12 to rotate through the connecting sleeve 11. The screw 12 rotates and engages with the transmission sleeve 16 through a threaded connection, thereby driving the support ring 17 to move through the transmission sleeve 16. The support ring 17 pushes multiple sets of top blocks 18 to move upward. The top of the top block 18 abuts against the flow control plate 15, causing the flow control plate 15 to rotate along the support rod 14. At the same time, one side of the flow control plate 15 compresses the compression spring 22. An adjustable flow space is formed between the multiple sets of flow control plates 15. The preset force of the compression spring 22 is set to be greater than the water flow pressure at the factory.

[0040] After the motor 26 starts, the rotation of the lead screw 27 drives the transmission block 28 to move. The transmission block 28 is mounted on the moving plate 25, thereby causing the moving plate 25 to slide on the mounting frame 23. The guide rail 31 is mounted on the mounting frame 23 to ensure that the moving plate 25 remains stable during the sliding process. By moving the moving plate 25, the position of the diversion box 29 can be adjusted, thereby changing the water flow path in the drainage hopper 7. The water flows into the diversion box 29 through the trough 30, and then flows into the drainage hopper 7 through the through groove 24, realizing precise control of the drainage height. The position adjustment of the diversion box 29 can adapt to different treatment needs, ensuring that the treated clean water can be discharged evenly.

[0041] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
