Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, specifically to a device for upgrading the effluent from wastewater treatment plants. Background Technology
[0002] In modern society, upgrading the standards of wastewater treatment plant effluent is of great significance. Wastewater treatment plant effluent refers to the water discharged from wastewater treatment plants after conventional treatment processes. With the increasing awareness of environmental protection and the increasingly stringent relevant laws and standards, the requirements for effluent water quality have been greatly improved. On the one hand, in order to better protect the natural aquatic ecological environment and prevent residual pollutants in the effluent from polluting rivers, lakes and seas, thereby causing problems such as eutrophication and ecological imbalance, it is necessary to upgrade the treatment of effluent. On the other hand, the recycling of water resources is also inseparable from the upgrading of effluent standards. Upgraded effluent can be used for industrial cooling, urban greening irrigation, etc., effectively alleviating the pressure of water shortage.
[0003] Traditional effluent upgrading technologies have many shortcomings. Traditional biological treatment technologies are limited by the survival conditions of microorganisms. At low temperatures, the activity of microorganisms decreases, and their ability to decompose and transform pollutants such as nitrogen and phosphorus in effluent drops significantly, making it difficult for the treated effluent to meet discharge standards. Moreover, traditional physical sedimentation technologies are not effective in removing some dissolved pollutants and fine particles. These residual pollutants not only affect the appearance of the effluent but may also cause corrosion and blockage of equipment during reuse, reducing equipment lifespan and increasing maintenance costs. This seriously hinders the effluent reuse process and cannot meet the current demand for high-quality treatment and efficient utilization of effluent. Therefore, we propose an effluent upgrading device for wastewater treatment plants. Utility Model Content

[0014] (III) Beneficial Effects
[0015] Compared with the prior art, this utility model provides a device for upgrading the effluent from wastewater treatment plants, which has the following beneficial effects:
[0016] 1. This wastewater treatment plant effluent upgrading device has multiple sets of linearly distributed filter plates at equal intervals inside the impurity removal tank, which can initially intercept large particulate impurities and reduce the burden of subsequent treatment. The stirring structure at the top of the filter tank, driven by a stirring motor, allows the reagents and wastewater to be fully mixed and reacted, enhancing the removal capacity of pollutants. In addition, the pressurized air pipe in the air blowing structure blows air into the filter tank, which can promote the separation and sedimentation of pollutants in the wastewater, further improving the treatment effect.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figures 1-4 This device, used for upgrading the effluent from a wastewater treatment plant, includes a base plate 1, which is L-shaped. A debris removal box 2 is fixedly installed on the top of one side of the base plate 1. A connecting pipe 5 is fixedly connected to the side of the debris removal box 2. A filter tank 6 is fixedly connected to the other end of the connecting pipe 5. A stirring structure is provided on the top of the filter tank 6. A control box fixing plate 9 is fixedly installed on the outer side of the filter tank 6. A control structure is provided on the top of the control box fixing plate 9. A wastewater treatment outlet 12 is opened on the outer side of the filter tank 6 near the bottom. A control valve 13 is fixedly installed on the outer side of the wastewater treatment outlet 12. A sediment outlet 14 is fixedly connected to the bottom of the filter tank 6. An extraction and pressurization structure is fixedly connected to the other end of the sediment outlet 14. A bracket 17 is fixedly installed on the top of the base plate 1 and next to the extraction and pressurization structure. A vibration structure is provided on the top of the bracket 17. An air blowing structure is provided on the outer wall of the filter tank 6 corresponding to the side of the bracket 17.
[0026] Furthermore, a baffle 3 is fixedly installed on the top of the impurity removal box 2. The surface of the baffle 3 has a through groove. Multiple sets of filter plates 4 are fixedly installed inside the impurity removal box 2 in a linearly distributed manner at equal intervals. The baffle 3 of the impurity removal box 2 can not only prevent sewage splashing, but its through groove design can also play a preliminary screening role to a certain extent according to the sewage flow and impurity characteristics. When the sewage flow is large, the through groove can make the water flow more evenly dispersed into the impurity removal box, avoiding the impact of excessive local water flow on the filter plates 4. The multiple sets of filter plates 4 are distributed at equal intervals, and the spacing is designed with precise calculation. Different spacing can intercept impurities of different particle size ranges. For example, filter plates with larger spacing intercept larger floating objects first, while filter plates with smaller spacing are responsible for intercepting smaller particles, ensuring the comprehensiveness and efficiency of the impurity removal effect. Moreover, this layout facilitates the disassembly, cleaning and replacement of filter plates 4 in the later stage. Maintenance personnel can deal with the clogging of filter plates one by one according to the clogging of filter plates, reducing maintenance costs and time.
[0027] Furthermore, the stirring structure includes a sealing cover 7 and a stirring motor 8. The sealing cover 7 is fixedly installed on the top of the filter tank 6 and is connected to the filter tank 6 by bolts. A motor mounting base is fixedly installed on the top of the sealing cover 7, and the stirring motor 8 is fixedly installed on the top of the motor mounting base. The output shaft of the stirring motor 8 is fixedly connected to a stirring shaft. In addition to providing a mounting platform for the stirring motor 8, the sealing cover 7 can effectively prevent wastewater and chemical vapors in the filter tank 6 from evaporating into the external environment, avoiding air pollution and chemical waste. At the same time, during the stirring process, the sealing cover 7 can maintain a relatively stable environment inside the filter tank 6, preventing external impurities from entering. Motor 8 has a variable frequency speed control function. Operators can precisely adjust the speed of stirring motor 8 through control box 10 according to the nature of wastewater, treatment stage and reaction characteristics of the agent. In the initial stage of adding flocculant, a higher speed can make the flocculant disperse quickly and evenly in the wastewater. As the reaction proceeds, the speed can be appropriately reduced to ensure that the agent and wastewater continue to react and avoid excessive stirring that will destroy the already formed floc structure. The shape of the stirring shaft and the design of the blades have also been specially optimized. The angle and curvature of the blades can generate a specific water flow pattern during stirring, which promotes the mixing of wastewater and agent, and at the same time enhances the circulation effect of wastewater in the tank, making the reaction more complete.
[0028] Furthermore, the control structure includes a control box 10 and a pressure gauge 11. The control box 10 is fixedly installed on the top of the control box mounting plate 9, and the pressure gauge 11 is fixedly installed on the side of the control box 10. Control buttons are provided on the outer surface of the control box 10. In addition to controlling the operating status of the stirring motor 8 and the air pump 24, the control box 10 also has fault diagnosis and alarm functions. When a component of the device malfunctions, such as overload of the stirring motor 8 or abnormal pressure of the air pump 24, the control box 10 can quickly detect the fault signal and issue an audible and visual alarm through the built-in alarm device. At the same time, detailed fault information is displayed on the display screen of the control box 10. The pressure gauge 11 displays the pressure inside the filter tank 6 in real time, and its data is also transmitted to the control system of the control box 10 for comparison with the preset pressure threshold. Once the pressure exceeds the normal range, the control system will automatically adjust the operating parameters of the relevant equipment, such as reducing the speed of the stirring motor 8 or adjusting the working frequency of the air pump 24, to maintain the pressure stability inside the filter tank 6 and ensure the safe and stable operation of the device. The control buttons adopt a user-friendly design, with clear distinctions between buttons of different functions, and have anti-misoperation functions to prevent operators from accidentally touching the buttons and causing abnormal operation of the equipment.
[0029] Furthermore, the vibration structure includes a buffer spring 18, a screen plate 19, and a vibrator 20. The buffer spring 18 is fixedly installed at the top of the four corners of the bracket 17. The screen plate 19 is fixedly installed on the top of the buffer spring 18. The vibrator 20 is fixedly installed on the side of the screen plate 19. A solid outlet hopper 21 is fixedly installed on the side of the screen plate 19. A set of fixing frames is fixedly installed on the outer walls of both sides of the screen plate 19. A telescopic cylinder 22 is fixedly installed in the center of the fixing frame. A pressure plate is fixedly connected to the bottom of the telescopic cylinder 22. A set of lifting cylinders 23 is fixedly installed below the fixing frame on the other side. A baffle is fixedly installed at the bottom of the lifting cylinder 23. In addition to reducing the impact of vibration on the equipment, the buffer spring 18 can also automatically adjust the height and angle of the screen plate 19 according to the weight of the solid impurities on the screen plate 19 and the vibration. When there are many solid impurities on the screen plate 19 and the weight is large, the buffer spring 18 will be appropriately compressed to keep the screen plate 19 at a certain position. A more stable working height is achieved, and the tilt angle of the screen 19 is adjusted to facilitate the sliding of solid impurities into the solid outlet hopper 21 under vibration. The vibration frequency and amplitude of the vibrator 20 can be adjusted according to actual processing needs. Different parameters can be set through the control box 10 to adapt to the separation of solid impurities with different particle sizes and properties. For example, for impurities with smaller particle sizes and higher viscosity, the vibration frequency and amplitude can be increased to enhance the separation effect. The actions of the telescopic cylinder 22 and the lifting cylinder 23 are coordinated with the operation of the vibrator 20. During vibration, the telescopic cylinder 22 can extend the pressure plate in time to squeeze the impurities according to the accumulation of solid impurities, making the gaps between impurities smaller and more conducive to passing through the screen holes of the screen 19. The lifting cylinder 23 can adjust the height of the baffle according to the blockage of the solid outlet hopper 21 to control the discharge speed of impurities, ensuring that solid impurities can be discharged smoothly and avoiding blockage.
[0030] Furthermore, the extraction pressurization structure includes a control valve 15 and a pressurization pump 16. One end of the control valve 15 is fixedly connected to the sediment outlet 14, and the other end of the control valve 15 is fixedly connected to the pressurization pump 16. The other end of the pressurization pump 16 is fixedly connected to the sieve plate 19. The bottom of the pressurization pump 16 is fixedly installed on the top of the base plate 1. The control valve 15 has flow regulation and backflow prevention functions, which can accurately control the flow rate of the extracted sediment to avoid affecting the treatment effect due to excessive or insufficient flow. At the same time, the backflow prevention function can prevent the sediment from flowing back into the filter tank 6, ensuring the unidirectionality of the treatment process. The pressurization pump 16 adopts variable frequency speed regulation technology, which automatically adjusts the pump speed according to the concentration of the sediment and the difficulty of extraction, reducing energy consumption while ensuring the extraction effect.
[0031] Furthermore, the air blowing structure includes an air blowing pump 24, a drying air pipe 25, and a pressurizing air pipe 26. The air blowing pump 24 is fixedly installed on the outer wall of the filter tank 6. The drying air pipe 25 is fixedly connected to the lower side of the air blowing pump 24, and the other end of the drying air pipe 25 enters the screen plate 19. The pressurizing air pipe 26 is fixedly installed on the upper side of the air blowing pump 24, and the other end of the pressurizing air pipe 26 enters the filter tank 6. The air pressure and flow rate output by the air blowing pump 24 can be precisely adjusted according to the operating status of the device. Inside the filter tank 6, the pressurizing air pipe 26 can make the airflow evenly distributed in the wastewater, promoting the separation and sedimentation of pollutants. For different densities... By adjusting the pressure of the air pump 24, lighter pollutants can rise faster under the action of airflow, while heavier pollutants can sink more quickly. At the sieve tray 19, the airflow blown out by the drying air pipe 25 not only assists in the separation of solid impurities but also cleans the sieve tray 19 in real time. When solid impurities are separated on the sieve tray 19, the airflow from the drying air pipe 25 can blow away the tiny particles attached to the screen holes, preventing the screen holes from clogging and ensuring the screening efficiency of the sieve tray 19. In addition, the air pump 24 is also equipped with an air filter device, which can filter out impurities in the incoming air and prevent these impurities from entering the filter tank 6 or the sieve tray 19, thus affecting the treatment effect.

[0059] Working Principle: Wastewater first enters the impurity removal tank 2. A baffle 3 at the top of the tank prevents splashing, and its channel guides the wastewater in. Multiple sets of equidistantly distributed filter plates 4 inside intercept large particles such as leaves and twigs. The filter plates with different spacings specifically trap impurities of different sizes, effectively reducing the burden on subsequent treatment and ensuring stable equipment operation. After preliminary impurity removal, the wastewater enters the filter tank 6 through the connecting pipe 5. The stirring structure at the top of the filter tank 6 begins operation. The stirring motor 8, installed on the sealing cover 7, drives the stirring shaft to rotate, ensuring thorough mixing of the added chemicals with the wastewater. If flocculants are added, the stirring promotes uniform dispersion of the flocculants, causing them to flocculate with the small particulate pollutants in the wastewater, forming larger particles that facilitate subsequent sedimentation and separation, enhancing the overall performance. To enhance the removal capacity of pollutants, the control structure on the outer side of the filter tank 6 plays a crucial role in monitoring and regulating the equipment's operation. The pressure gauge 11 on the control box 10 displays the pressure inside the filter tank in real time. Based on the pressure data, operators adjust the speed of the stirring motor 8 and the operating status of the air pump 24 via the control buttons on the outside of the control box 10 to ensure the device operates under optimal conditions. When the pressure is too high, the stirring speed can be reduced or the air flow rate adjusted to maintain system stability. The sediment outlet 14 at the bottom of the filter tank 6 is connected to an extraction and pressurization structure, which includes a control valve 15 and a pressurization pump 16. The control valve 15 controls the sediment extraction flow rate and prevents backflow, while the pressurization pump 16 extracts the impurities and sludge settled at the bottom and transports them to subsequent treatment stages. To prevent sediment buildup from affecting the treatment effect, the vibration structure at the top of the support 17 works in conjunction with the air blowing structure on the outer wall of the filter tank 6. In the vibration structure, the vibrator 20 is installed on the side of the screen plate 19. After starting, the screen plate vibrates. At the same time, the air blowing pump 24 blows air into the screen plate 19 through the air drying pipe 25. Under the combined action of vibration and airflow, solid impurities are separated on the screen plate 19 and discharged through the solid outlet hopper 21. The telescopic cylinders 22 and lifting cylinders 23 on both sides of the screen plate 19 further assist in the separation and discharge of impurities. The pressure plate at the bottom of the telescopic cylinder 22 can squeeze the accumulated solid impurities, making them easier to pass through the screen holes. The baffle at the bottom of the lifting cylinder 23 controls the rhythm of impurity discharge and prevents blockage. The air blowing pump 24 blows air into the filter tank 6 through the pressurized air pipe 26. Air is blown into the filter tank 6 to promote the separation and sedimentation of pollutants in the wastewater. The airflow agitates the wastewater, causing tiny particles to collide and aggregate, accelerating the sedimentation process. The upward airflow causes lighter impurities to float up, making them easier to separate from the water. At the screen plate 19, the airflow blown out by the drying air pipe 25 can also clean the screen plate, prevent the screen holes from clogging, and ensure screening efficiency. After a series of treatments, impurities and pollutants in the wastewater are effectively removed. The treated water is discharged through the wastewater treatment outlet 12. The control valve 13 can control the outflow rate and time. When it is necessary to discharge the treated water, the control valve 13 is opened. The treated effluent that meets the standards can be used for industrial cooling, urban greening irrigation, etc., realizing the recycling of water resources, reducing pollution to natural water bodies, and achieving the purpose of upgrading the effluent treatment standards.
