Description

Technical Field

[0001] This invention relates to the field of deep wastewater purification technology, specifically to a dynamic interception and feedback system for deep purification of urban wastewater and a purification treatment method. Background Technology

[0002] Urban wastewater deep purification refers to a refined treatment process that, based on traditional wastewater treatment processes (such as physical sedimentation and biological treatment), further removes recalcitrant pollutants, nutrients (nitrogen / phosphorus), trace toxic substances, and pathogens from wastewater through multi-stage synergistic technologies, so that the effluent quality meets high standards for reuse or discharge.

[0003] When treating wastewater, filtration is often required beforehand to improve the subsequent treatment effect. However, continuous filtration can lead to excessive accumulation of impurities, hindering continuous filtration. This filtration process cannot achieve a dynamic interception effect, causing the accumulated impurities to fall off and affecting subsequent wastewater treatment.

[0004] Therefore, to address the above problems, a new dynamic interception and feedback-based deep purification device and method for urban sewage is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a dynamic interception and feedback-based deep purification device and method for urban sewage to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a dynamic interception and feedback urban sewage deep purification device, comprising: a reaction tank, in which a reaction device is fixedly installed, and a connecting pipe is symmetrically fixedly installed on one side of the reaction tank, one end of which is connected to the reaction device; an inlet unit, which is fixedly installed at the top of one end of the reaction tank, and a fixed bracket is fixedly installed at the center of the end of the reaction tank near the inlet unit, on which two filter frames are symmetrically arranged; and a drive mechanism, which is fixedly installed on one side of the reaction tank, and the output end of the drive mechanism... The drive mechanism includes a side frame fixedly installed at the end of the reaction tank, which is fixedly connected to one end of each of the two filter frames. A fixed frame is fixedly installed on one side of the side frame, and a bevel gear structure is rotatably connected inside the fixed frame. Fixed angle plates are symmetrically fixedly installed on the side of the side frame away from the reaction tank. Transmission rods are symmetrically rotatably connected on both sides of the side frame, and the ends of the two transmission rods away from the side frame are rotatably connected to the two fixed angle plates respectively. An installation frame is fixedly installed on one side of the side frame. The start-stop mechanism is fixedly installed at the top of the two water inlet units, and the output end of the start-stop mechanism is in transmission cooperation with the water inlet units.

[0007] Furthermore, the start / stop mechanism includes a control valve fixedly installed on the water inlet unit. A mounting base is fixedly installed on the top of the control valve, and a fixing plate is installed on the top of the mounting base. A mounting bracket is fixedly installed on one side of the fixing plate, and a drive motor is installed on the top of the mounting bracket. A first worm and a first worm wheel are rotatably connected inside the fixing plate, and the first worm wheel is meshed with the first worm. A drive gear is fixedly installed at the bottom of the first worm wheel, and a transmission rack is meshed with one side of the drive gear. The transmission rack is meshed with a matching gear for driving the operation of the control valve. Water level sensors are fixedly installed on the side walls of the two filter frames, and the water level sensors are electrically connected to the drive motor.

[0008] Furthermore, the drive mechanism also includes a working motor fixedly mounted on the top of the mounting frame. The mounting frame is rotatably connected to a second worm and a second worm wheel, and the second worm wheel and the second worm are meshed together. The inner side of the side frame is symmetrically rotatably connected to a sprocket structure. One end of each sprocket structure passes through the side wall of the side frame and is fixedly mounted with a connecting rod. Both ends of the top of the fixed bracket are fixedly mounted with mounting supports, which are rotatably connected to the connecting rods. The connecting rods are fixedly connected to one end of the filter frame, and the other end of the sprocket structure passes through the side wall of the side frame and is fixedly connected to one end of the bevel gear set.

[0009] Furthermore, the fixing frame is square in shape and is used to install the bevel gear structure.

[0010] Furthermore, a filter plate is rotatably connected inside the filter frame, and guide grooves are symmetrically opened on the inner wall of the filter frame. The filter plate is slidably connected to the guide grooves at its rotating end.

[0011] Furthermore, a number of counterweights are fixedly installed at equal intervals on the sliding end of the filter plate, and the counterweights are fixedly connected to each other by ribs.

[0012] Furthermore, an inclined plate is fixedly installed inside the filter frame at the end closest to the water level sensor.

[0013] Furthermore, a side frame is fixedly installed at the top of the filter frame, away from the water level sensor, and an interception net is fixedly installed on the side frame.

[0014] This invention also provides a method for deep purification treatment of urban sewage with dynamic interception and feedback, comprising:

[0015] S1, Primary Interception

[0016] Urban sewage enters the reaction tank through the inlet unit and flows through the filter frame; the filter frame physically intercepts large suspended solids in the sewage, achieving primary purification.

[0017] S2, Dynamic monitoring feedback trigger

[0018] When wastewater accumulates inside the filter frame, causing the water level to rise, the water level sensor monitors the accumulated water level in real time. When the preset warning water level is reached, the signal is transmitted to the start-stop mechanism, which then shuts off the water intake of the inlet unit.

[0019] S3. Cleaning of suspended solids and restarting of the device.

[0020] After the water inlet unit is shut off, the drive mechanism starts working, driving the filter frame to rotate, thereby emptying the suspended matter inside in time. Then, the drive mechanism controls the filter frame to reset. After that, the start-stop mechanism controls the water inlet unit to start water intake again, and the purification process begins again.

[0021] The technical solution provided by this invention may include the following beneficial effects:

[0022] 1. In this example, the start-stop mechanism can not only quickly cut off the inlet water to prevent sewage and suspended solids from continuously flowing into the reaction tank and effectively protect the stable operation of subsequent purification processes, but also buy time for staff to clean the suspended solids in the filter frame, reducing the frequency and intensity of manual inspections. At the same time, by precisely controlling the timing of water inlet, equipment damage caused by excessive clogging of the filter frame can be avoided, extending the service life of the filter components, reducing system maintenance costs, and ensuring the efficient, stable, and low-consumption operation of the entire sewage purification system.

[0023] 2. In this example, the drive mechanism eliminates the need for manual disassembly or tilting of the filter frame, significantly reducing the physical labor required by workers and avoiding the inefficiency and safety hazards that may result from manual operation. Especially in the scenario of continuous operation of the sewage purification system, it can effectively reduce the intensity and frequency of manual maintenance.

[0024] 3. In this example, the filter plate can be adjusted in angle as the filter frame rotates, which makes it easier to pour out the intercepted suspended solids and avoids the residue of suspended solids. In addition, after the filter frame is rotated to a certain angle, the counterweight can be used to drive the filter plate to rotate further, ensuring that the suspended solids can be discharged from the filter frame more thoroughly and reducing cleaning dead corners. When the filter frame is reset, the counterweight block can assist the filter plate to reset quickly with the change of angle, without affecting the subsequent filtration operation.

[0038] The technical solutions of the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0039] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The dynamic interception and feedback urban sewage deep purification equipment specifically includes: a reaction tank 1, with a reaction device 2 fixedly installed inside the reaction tank 1, and connecting pipes 3 symmetrically fixedly installed on one side of the reaction tank 1, one end of which is connected to the reaction device 2; an inlet unit 4, which is fixedly installed on the top of one end of the reaction tank 1, and a fixed bracket 6 is fixedly installed in the center of the end of the reaction tank 1 near the inlet unit 4, with two filter frames 7 symmetrically arranged on the fixed bracket 6; and a drive mechanism 9, which is fixedly installed on one side of the reaction tank 1, with the output end of the drive mechanism 9 fixedly connected to one end of each of the two filter frames 7. The system includes a side frame 31 fixedly installed at the end of the reaction tank 1, a fixed frame 32 fixedly installed on one side of the side frame 31, a bevel gear structure 33 rotatably connected inside the fixed frame 32, fixed angle plates 34 symmetrically fixedly installed on the side of the side frame 31 away from the reaction tank 1, transmission rods 35 symmetrically rotatably connected on both sides of the side frame 31, and the ends of the two transmission rods 35 away from the side frame 31 respectively rotatably connected to the two fixed angle plates 34, and an installation frame 37 fixedly installed on one side of the side frame 31; a start-stop mechanism 10, which is fixedly installed at the top of the two water inlet units 4, and the output end of the start-stop mechanism 10 is in transmission cooperation with the water inlet unit 4.

[0040] Specifically, the start / stop mechanism 10 includes a control valve 21 fixedly installed on the water inlet unit 4. A mounting base 22 is fixedly installed on the top of the control valve 21. A fixing plate 23 is installed on the top of the mounting base 22. A mounting bracket 24 is fixedly installed on one side of the fixing plate 23. A drive motor 25 is installed on the top of the mounting bracket 24. A first worm 26 and a first worm wheel 27 are rotatably connected inside the fixing plate 23. The first worm wheel 27 is meshed with the first worm 26. A drive gear 28 is fixedly installed at the bottom of the first worm wheel 27. A transmission rack 29 is meshed with one side of the drive gear 28. A mating gear 30 is meshed with the transmission rack 29 for driving the operation of the control valve 21. Water level sensors 8 are fixedly installed on the side walls of the two filter frames 7 respectively. The water level sensors 8 are electrically connected to the drive motor 25.

[0041] Specifically, the drive mechanism 9 also includes a working motor 38 fixedly installed at the top of the mounting frame 37. The second worm 39 and the second worm wheel 40 are rotatably connected inside the mounting frame 37, and the second worm wheel 40 and the second worm 39 are meshed together. The inner side of the side frame 31 is symmetrically rotatably connected to a sprocket structure 41. One end of the two sprocket structures 41 passes through the side wall of the side frame 31 and is fixedly installed with a connecting rod 14. Both ends of the top of the fixed bracket 6 are fixedly installed with mounting supports 13, which are rotatably connected to the connecting rods 14. The connecting rods 14 are fixedly connected to one end of the filter frame 7, and the other end of the sprocket structure 41 passes through the side wall of the side frame 31 and is fixedly connected to one end of the bevel gear set 36.

[0042] Specifically, the fixed frame 32 is square and is used to install the bevel gear structure 33. It can stably install four bevel gears of the same specification, thereby smoothly driving the two transmission rods 35 in opposite directions, which in turn drives the two filter frames 7 to rotate, thereby realizing the dumping of suspended matter.

[0043] Specifically, a filter plate 16 is rotatably connected inside the filter frame 7, and guide grooves 17 are symmetrically opened on the inner wall of the filter frame 7. The filter plate 16 is slidably connected to the guide grooves 17 at its rotating end. The rotatable filter plate 16 inside the filter frame 7 can increase the convenience of emptying suspended matter. In addition, the guide grooves 17 can increase the stability of the filter plate 16 when rotating, further improving the stability of the device during use.

[0044] Specifically, a number of counterweights 18 are fixedly installed at equal intervals on the sliding end of the filter plate 16. The counterweights 18 are fixedly connected to each other by ribs 19. The counterweights 18 and ribs 19 at the end of the filter plate 16 can drive the filter plate 16 to rotate after the filter frame 7 rotates to a certain angle, thereby better dumping the suspended matter. In addition, during the reset process of the filter frame 7, when the filter plate 16 rotates to a certain angle, the filter plate 16 is pressed down, so that the filter plate 16 can quickly reset.

[0045] Specifically, an inclined plate 20 is fixedly installed inside the end of the filter frame 7 near the water level sensor 8. The inclined plate 20 can limit the accumulation position of suspended solids, causing them to accumulate near the rotating end of the filter frame 7, making it easier for the filter frame 7 to rotate and preventing suspended solids from falling when tilted.

[0046] Specifically, a side frame 11 is fixedly installed on the top end of the filter frame 7 away from the water level sensor 8, and an intercepting net 12 is fixedly installed on the side frame 11. The side frame 11 and the intercepting net 12 are designed to limit the rotation of the filter frame 7 by the drive mechanism 9 to pour out the suspended matter, thus preventing the suspended matter from falling from both sides of the filter frame 7 and contaminating the reaction tank 1 during pouring. In addition, the side frame 11 increases the depth of the filter frame 7, allowing the filter frame 7 to concentrate the suspended matter during pouring, making it easier for the filter frame 7 to rotate.

[0047] In this embodiment, how to generate dynamic interception feedback is described in reference [reference needed]. Figures 1 to 5 and Figure 7The specific implementation method is as follows: In the wastewater purification process, wastewater is first transported through the inlet unit 4. Before entering the reaction tank 1 for core purification, it flows into the filter frame 7. As a pre-filtration device, the filter frame 7 can effectively intercept suspended impurities in the wastewater, initially reducing the turbidity of the wastewater, reducing the load on the subsequent purification operation of the reaction device 2, and improving the overall purification efficiency. However, as the filtration process continues, the intercepted suspended solids will gradually accumulate inside the filter frame 7. These accumulated suspended solids will clog the filter holes of the filter frame 7, causing its filtration efficiency to decrease significantly. If not treated in time, not only will a large amount of wastewater and suspended solids accumulate in the filter frame 7, but the wastewater containing high concentrations of suspended solids may also directly enter the reaction tank 1 due to insufficient filtration capacity. This will seriously interfere with the full reaction between the purification agent and the wastewater in the reaction device 2, reducing the removal of pollutants. The removal rate ultimately affects the wastewater purification effect and may even lead to substandard effluent quality. The device is equipped with a start-stop mechanism 10, which can monitor the liquid level in the filter frame 7 in real time. The water level sensor 8 can accurately capture the liquid level change information. When the drainage speed of the filter frame 7 slows down and the liquid level gradually rises due to blockage by suspended matter, the water level sensor 8 will promptly feed back the liquid level data to the system controller. When the liquid level rises to the preset warning threshold, the controller will quickly send a command to the drive motor 25 to trigger the start-stop action. The drive motor 25 drives the first worm 26 and the first worm wheel 27 to rotate synchronously, thereby driving the drive gear 28 to rotate. The drive gear 28 then drives the two transmission racks 29 to move through meshing. The transmission racks 29 and the mating gear 30 work together to finally drive the control valve 21 to close the water flow channel of the water inlet unit 4.

[0048] In this embodiment, how to begin quickly cleaning the suspended matter accumulated inside the filter frame 7 is described in reference [reference needed]. Figure 6The specific implementation method is as follows: When the suspended matter in the filter frame 7 accumulates to the point where it needs to be cleaned, the system will automatically start the cleaning process. Power is provided by the working motor 38 in the drive mechanism 9. The working motor 38 first drives the second worm 39 and the second worm wheel 40 to rotate synchronously. Through the transmission action of the worm and worm wheel, the power is transmitted to the bevel gear structure 33, causing the bevel gear structure 33 to rotate accordingly. Subsequently, the power is transmitted to the bevel gear set 36 through the transmission rod 35. The bevel gear set 36 further changes the direction of power and drives the sprocket structure 41 to rotate. As the sprocket structure 41 rotates, it drives the connected components through the meshing relationship. The rod 14 moves, and the connecting rod 14 is fixedly connected to the filter frame 7, so it will drive the filter frame 7 to rotate synchronously. During the rotation, the filter frame 7 gradually moves out of the inside of the fixed bracket 6. After rotating to a suitable angle, the filter frame 7 will automatically complete the tilting action of suspended solids, and completely discharge the impurities accumulated inside. With the setting of the drive mechanism 9, the filter frame 7 can be disassembled or tilted manually without manual labor, which greatly reduces the amount of physical labor of workers and avoids the inefficiency and safety hazards that may be caused by manual operation. Especially in the scenario of continuous operation of sewage purification system, it can effectively reduce the intensity and frequency of manual maintenance.

[0049] It is important to note that the working motor 38, the drive motor 25, and the system controller maintain a close signal connection, forming an efficient linkage control logic. When the start-stop mechanism 10 completes the water shut-off operation of the inlet unit 4, the controller will immediately transmit the start cleaning signal to the working motor 38 to ensure that the drive mechanism 9 is started quickly after the water is shut off, avoiding the long-term retention of suspended matter in the filter frame 7, which may cause clumping or secondary blockage. After the filter frame 7 has finished emptying the suspended matter and accurately reset, the controller will promptly send the reset signal back to the start-stop mechanism 10. The start-stop mechanism 10 then controls the control valve 21 to open, allowing the inlet unit 4 to re-enter water, so that the entire sewage purification system can seamlessly enter the next "inlet-filtration-purification-cleaning" cycle.

[0050] It should also be noted that this device not only achieves precise connection between the cleaning and water intake processes, avoiding the problem of excessive system downtime caused by the time difference of manual operation and ensuring the continuity of sewage purification, but also ensures the cleaning effect and reset accuracy of filter frame 7 through standardized operating procedures, further improving the service life of filter components. At the same time, it eliminates the need for manual judgment of cleaning timing and equipment operation, reducing the impact of human error on system operation. This enables the entire sewage purification system to achieve lower operation and maintenance costs and a higher level of intelligence while operating efficiently and stably.

[0051] This invention also provides a method for deep purification treatment of urban sewage with dynamic interception and feedback, comprising:

[0052] S1, Primary Interception

[0053] Urban sewage enters reaction tank 1 through inlet unit 4 and flows through filter frame 7; the filter frame 7 physically intercepts large suspended solids in the sewage to achieve primary purification.

[0054] S2, Dynamic monitoring feedback trigger

[0055] When wastewater accumulates inside the filter frame 7, causing the water level to rise, the water level sensor 8 monitors the accumulated water level in real time. When the preset warning water level is reached, the signal is transmitted to the start-stop mechanism 10, which then shuts off the water inlet of the water inlet unit 4.

[0056] S3. Cleaning of suspended solids and restarting of the device.

[0057] After the water inlet unit 4 is shut off, the drive mechanism 9 starts working, driving the filter frame 7 to rotate, thereby emptying the suspended matter inside in time. Then, the drive mechanism 9 controls the filter frame 7 to reset. After that, the start / stop mechanism 10 controls the water inlet unit 4 to start water intake again, and the purification process begins again.
