Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to an energy-saving and emission-reducing urban wastewater treatment system. Background Technology

[0002] Energy-saving and emission-reduction urban wastewater treatment systems, based on traditional wastewater treatment systems, place greater emphasis on the efficient use of energy and energy conservation and emission reduction in the pollutant treatment process. Through process design, equipment selection, and intelligent operation management, they can achieve wastewater treatment standards while minimizing energy consumption and greenhouse gas emissions during the treatment process.

[0003] A search revealed Chinese Patent Publication No. CN207418525U, which discloses an energy-saving and emission-reducing urban sewage treatment system. Its structure includes a wastewater treatment tank, a fully intelligent sewage blocker, a sewage heat pump unit, radiators, a hot water supply unit, a filter screen, a dust and sand tank, a water pump, a disinfection tank, a secondary sedimentation tank, an aeration tank, and a primary sedimentation tank. The disinfection tank is installed on the right side of the secondary sedimentation tank and connected by a pipe. The dust and sand tank is fixed to the left side of the water pump with an interference fit. The filter screen has a dust and sand tank installed on the left side and connected by a pipe. The wastewater treatment tank is installed on the left side of the fully intelligent sewage blocker and is interconnected. This system achieves the purpose of fully filtering sewage and reducing environmental damage. In actual use, when cleaning the solid particles accumulated at the bottom of the sedimentation tank, the upper layer of water in the sedimentation tank is discharged, and the bottom of the sedimentation tank is cleaned manually. However, if the drain outlet is set too high, some water will remain at the bottom of the sedimentation tank; if the drain outlet is set too low, some sediment will be discharged with the water flow. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an energy-saving and emission-reducing urban sewage treatment system, which aims to improve the problem of excessive water retention at the bottom of the pool and outflow of sediment caused by improper setting of the drainage outlet in the existing technology.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an energy-saving and emission-reducing urban sewage treatment system, including a sedimentation tank, a drainage mechanism on the right side of the sedimentation tank for system drainage, a drive component on the top of the drainage mechanism for driving the drainage mechanism, a climbing component on the left side of the inner wall of the sedimentation tank for workers to climb, a rinsing component on the front side of the sedimentation tank for cleaning the sedimentation tank, and a cleaning mechanism on the right side of the inner wall of the sedimentation tank.

[0006] The drainage mechanism includes a connecting block 1, the left side of which is fixedly connected to the right side of the sedimentation tank. An opening is provided in the middle of the connecting block 1, and sealing grooves are provided around the inner wall of the opening. A movable sealing baffle is slidably connected to the inner wall of the sealing groove. Limiting grooves are provided on the front and rear sides of the inner wall of the sealing groove. Slider blocks are fixedly connected to the front and rear sides of the movable sealing baffle. The outer walls of the two sliders are slidably connected to the inner walls of the corresponding limiting grooves. A movable drain outlet is provided at the top of the movable sealing baffle.

[0007] Through the above technical solution: because the movable sealing baffle is slidably connected in the sealing groove around the inner wall of the opening, and the sliders on the front and rear sides of the movable sealing baffle slide in cooperation with the limiting grooves on the front and rear sides of the inner wall of the sealing groove, the movable sealing baffle can move stably in the sealing groove. The slider moves, thereby driving the movable sealing baffle to move, so that the position and size of the movable drain outlet are changed, realizing precise control of drainage flow and drainage position, and meeting different drainage needs.

[0008] As a further description of the above technical solution:

[0009] The cleaning mechanism includes a filter screen, the outer wall of which is fixedly connected to the right side of the inner wall of the sedimentation tank. A mounting block is fixedly connected to the top of the sedimentation tank. A servo motor is fixedly connected to the inner wall of the mounting block. A lead screw is fixedly connected to the output end of the servo motor. A mounting plate is threadedly connected to the outer wall of the lead screw. A cleaning hanging plate is fixedly connected to the right side of the mounting plate. A limit component is provided on the top of the mounting plate.

[0010] Through the above technical solution: When the cleaning mechanism is working, once the servo motor starts, its output end drives the lead screw to rotate. Since the lead screw is threadedly connected to the mounting plate, the mounting plate will move up and down along the axial direction of the lead screw. The cleaning hanging plate fixed on the right side of the mounting plate moves accordingly, cleaning the filter screen fixed on the right side of the sedimentation tank inner wall. During the movement of the cleaning hanging plate, the impurities intercepted on the filter screen are scraped off, preventing the accumulation of impurities from affecting the filtration and drainage effect. The limiting component at the top of the mounting plate limits the movement range of the mounting plate, ensuring that it moves stably within the predetermined track, so that the cleaning hanging plate can accurately and effectively clean the filter screen.

[0011] As a further description of the above technical solution:

[0012] The drive assembly includes two mounting blocks 2. The bottoms of the two mounting blocks 2 are fixedly connected to the front and rear ends of the top right side of the sedimentation tank, respectively. Servo motor 2 is fixedly connected to the inner wall of each of the two mounting blocks 2. Lead screw 2 is fixedly connected to the output end of each of the two servo motor 2. The outer wall of each of the two lead screw 2 is threadedly connected to the inner wall of the corresponding slider.

[0013] Through the above technical solution: when the drive component is running, the two servo motors are powered on and started, and their respective output ends drive the lead screw to rotate. Since the lead screw is threadedly connected to the inner wall of the slider, the power generated by the rotation of the lead screw is converted into the linear motion of the slider along the lead screw. The slider is connected to the movable sealing baffle of the drainage mechanism, thereby driving the movable sealing baffle to slide in the sealing groove, realizing the control of the size and position of the drainage outlet, and completing the drainage operation.

[0014] As a further description of the above technical solution:

[0015] The climbing assembly includes a climbing ladder, the bottom of which is fixedly connected to the bottom left end of the inner wall of the sedimentation tank. The front and rear ends of the top left side of the climbing ladder are fixedly connected to fixing blocks. The left sides of the two fixing blocks are both connected to the left side of the inner wall of the sedimentation tank. Two handrails are fixedly connected to the top left side of the sedimentation tank.

[0016] The above technical solution provides a climbing component to facilitate workers' access to and from the sedimentation tank. During operation, workers use a climbing ladder to climb the tank. The bottom of the climbing ladder is securely connected to the bottom left side of the inner wall of the sedimentation tank, and its top left side is connected to the left side of the inner wall of the sedimentation tank via a fixing block to ensure the stability of the climbing ladder. The handrail on the top left side of the sedimentation tank provides auxiliary gripping for workers during the climbing process, enhancing climbing safety.

[0017] As a further description of the above technical solution:

[0018] The rinsing assembly includes a mounting frame, the bottom of which is fixedly connected to the top front side of the sedimentation tank. A nozzle is slidably connected to the top of the mounting frame. A water supply pipe is fixedly connected to the rear end of the nozzle. A water supply tank is fixedly connected to the bottom end of the water supply pipe. The rear side of the water supply tank is fixedly connected to the front side of the sedimentation tank.

[0019] The above technical solution involves a water tank storing rinsing water, which is then transported to the nozzles via a water supply pipe. The nozzles can slide on the top of the mounting frame, and the bottom of the mounting frame is fixed to the front of the top of the sedimentation tank, providing support and guidance. When rinsing is activated, the nozzles spray water, which slides on the mounting frame to thoroughly rinse the inner wall of the sedimentation tank, removing dirt and impurities and maintaining the cleanliness of the sedimentation tank.

[0020] As a further description of the above technical solution:

[0021] The limiting assembly includes two guide rods, the bottom ends of which are fixedly connected to the front and rear sides of the top of the mounting plate, respectively. Limiting rings are slidably connected to the outer walls of the two guide rods. Connecting blocks II are fixedly connected to the right sides of the two limiting rings. The right sides of the two connecting blocks II are fixedly connected to the front and rear ends of the right side of the inner wall of the sedimentation tank, respectively.

[0022] Through the above technical solution: the moving installation plate drives the guide rod to move synchronously, the limiting ring slides on the outer wall of the guide rod, the connecting block two connects the limiting ring to the right side of the inner wall of the sedimentation tank, the guide rod guides the movement of the installation plate, and the limiting ring and connecting block two restrict the movement range of the installation plate, so that the installation plate can only move within the specified trajectory, ensuring that the cleaning plate can stably clean the filter screen and avoiding the displacement of the installation plate from affecting the cleaning effect.

[0023] As a further description of the above technical solution:

[0024] The sedimentation tank has a flow channel at the bottom of its inner wall, and a sludge collection hopper is fixedly connected to the bottom of the inner wall of the flow channel.

[0025] Through the above technical solution, the sludge settled at the bottom flows down the guide channel under gravity and eventually converges into the sludge collection hopper, which facilitates centralized collection and treatment of sludge.

[0026] As a further description of the above technical solution:

[0027] Limiting blocks are fixedly connected to the top ends of the two guide rods, and buffer pads are fixedly connected to the bottom ends of the two limiting blocks. The bottoms of the two buffer pads are respectively attached to the top of the corresponding limiting rings. Buffer pads are fixedly connected to the front and rear sides of the top of the mounting plate, and the tops of the two buffer pads are respectively attached to the bottom of the corresponding limiting rings.

[0028] Through the above technical solution: the limiting ring rises with the mounting plate and approaches the limiting block, and the first buffer pad can reduce the impact and avoid rigid collisions. The limiting ring falls with the mounting plate and approaches the mounting plate, and the second buffer pad plays a role in buffering the impact force, protecting each component, and ensuring the stable operation of the limiting assembly and related structures.

[0029] This utility model has the following beneficial effects:

[0030] 1. In this utility model, when it is necessary to clean the solid particles at the bottom of the sedimentation tank, the drainage mechanism works, the drive component motor drives the lead screw to rotate, so that the movable sealing baffle moves in the slide groove, and the height of the drain outlet is adjusted as needed to avoid excessive water retention and sediment outflow. Workers can safely enter the tank to clean it with the help of the climbing component. After cleaning, the flushing component thoroughly cleans the inner wall of the tank, ensuring the efficient operation of the sedimentation tank and improving the system's energy saving, emission reduction and work efficiency.

[0031] 2. In this utility model, when the sedimentation tank drains, the sewage is filtered through the filter screen to prevent sediment from flowing out. However, sediment tends to accumulate on the filter screen, affecting drainage. At this time, the cleaning mechanism works. The motor drives the lead screw to rotate, causing the mounting plate to move up and down along the lead screw. The cleaning hanging plate on its right side scrapes the filter screen, scraping the sediment to the bottom of the tank, ensuring smooth drainage. At the same time, the limiting component stabilizes the movement of the mounting plate. It consists of a guide rod and a limiting ring to prevent the mounting plate from shifting, ensuring accurate and stable cleaning and maintaining the drainage function of the sedimentation tank.

The limiting grooves 205 limit the sliders 206, ensuring that the movable sealing baffle 204 moves stably within a specified range. Slider 206 is fixedly connected to both the front and rear sides of the movable sealing baffle 204. The sliders 206 cooperate with the limiting grooves 205 to make the movement of the movable sealing baffle 204 more stable and accurate. The outer walls of the two sliders 206 The movable sealing baffle 204 is slidably connected to the inner wall of the corresponding limiting groove 205. A movable drain outlet 207 is provided on the top of the movable sealing baffle 204. The movable drain outlet 207 changes position and size as the movable sealing baffle 204 moves, achieving flexible drainage. The drive assembly 4 includes two mounting blocks 401, which are used to fix the servo motor 402, providing a stable mounting base. The bottoms of the two mounting blocks 401 are fixedly connected to the front and rear ends of the top right side of the sedimentation tank 1, respectively. Servo motors 402 are fixedly connected to the inner walls of both mounting blocks 401. The servo motors 402 serve as a power source, providing power for the rotation of the lead screw 403.

The climbing assembly 5 includes a climbing ladder 501, which provides a climbing passage for workers to enter and exit the sedimentation tank 1. The bottom end of the climbing ladder 501 is fixedly connected to the bottom left end of the inner wall of the sedimentation tank 1. Fixing blocks 502 are fixedly connected to the front and rear ends of the top left side of the climbing ladder 501. The fixing blocks 502 securely connect the climbing ladder 501 to the left side of the inner wall of the sedimentation tank 1, ensuring the stability of the climbing ladder 501. The left sides of the two fixing blocks 502 are both connected to the left side of the inner wall of the sedimentation tank 1. Two handrails 503 are fixedly connected to the top left side of the sedimentation tank 1. The handrails 503 are for workers. The system provides gripping support for climbing, enhancing safety. The rinsing assembly 6 includes a mounting bracket 601, which supports the nozzle 602, ensuring it operates in the correct position. The bottom end of the mounting bracket 601 is fixedly connected to the top front of the sedimentation tank 1. The nozzle 602 is slidably connected to the top of the mounting bracket 601, allowing it to slide on top of the bracket 601, expanding the cleaning range and achieving more comprehensive cleaning of the inner wall of the sedimentation tank 1. A water supply pipe 603 is fixedly connected to the rear end of the nozzle 602, supplying water from the water supply tank 604 to the nozzle 602 for cleaning. The bottom end of the water supply pipe 603 is fixedly connected to the water supply tank 604, which stores water for cleaning the sedimentation tank 1, ensuring sufficient water for cleaning. The rear side of the water supply tank 604 is fixedly connected to the front side of the sedimentation tank 1.

[0041] Specifically, the two servo motors 402 in the drive assembly 4 are started, driving the lead screw 403 to rotate. Since the lead screw 403 is threadedly connected to the inner wall of the slider 206, and the slider 206 is fixedly connected to the movable sealing baffle 204, the movable sealing baffle 204 will move up and down within the sealing groove 203. By controlling the rotation of the servo motors 402, the height of the movable drain outlet 207 can be adjusted. In this way, a large amount of water will not remain at the bottom of the pool due to the drain outlet being set too high, affecting cleaning, nor will sediment be discharged with the water due to the drain outlet being too low. This allows for on-demand control of the water level when draining solid particles at the bottom of the sedimentation tank 1, avoiding the problems of excessive water retention and sediment outflow at the bottom of the pool caused by improper drain outlet settings in traditional drainage methods, thus improving cleaning efficiency and effectiveness. When staff need to enter the sedimentation tank 1... During cleaning operations, climbing assembly 5 and climbing ladder 501 are fixed to the bottom left end of the inner wall of sedimentation tank 1.

Together with the overall drainage, climbing, and cleaning process, they can ensure the efficient operation of sedimentation tank 1 and improve the energy saving and emission reduction effect and work efficiency of the entire sewage treatment system.

[0042] Reference Figure 2 , Figure 3 and Figure 4The cleaning mechanism 3 includes a filter screen 301, which is used to intercept impurities in the sewage. The outer wall of the filter screen 301 is fixedly connected to the right side of the inner wall of the sedimentation tank 1, ensuring that the filter screen 301 can be securely installed in the sedimentation tank 1 and perform its filtering function normally. A mounting block 302 is fixedly connected to the top of the sedimentation tank 1, providing a mounting position for the servo motor 303 and ensuring that the motor is securely installed. The inner wall of the mounting block 302 is fixedly connected to the servo motor 303. As a power source, the servo motor 303 provides power for the rotation of the lead screw 304. The output end of the servo motor 303 is fixedly connected to the lead screw 304. The lead screw 304 rotates under the drive of the servo motor 303 to realize the movement of related components. The outer wall of the lead screw 304 is threadedly connected to the mounting plate 305, so that the mounting plate 305 can move along the direction of the lead screw as the lead screw 304 rotates. The right side of the mounting plate 305 is fixedly connected to the cleaning hanging plate 306, which moves with the mounting plate 305 and is used for scraping. In addition to removing impurities accumulated on the filter screen 301, a limiting component 307 is provided on the top of the mounting plate 305. The limiting component 307 limits and stabilizes the movement of the mounting plate 305. The limiting component 307 includes two guide rods 3071, which provide sliding tracks for the limiting ring 3072, guiding the movement direction of the mounting plate 305. The bottom ends of the two guide rods 3071 are fixedly connected to the front and rear sides of the top of the mounting plate 305, respectively, securely mounting the guide rods 3071 onto the mounting plate 305. The outer wall of the guide rod 3071 is slidably connected to the limiting ring 3072. The limiting ring 3072 slides on the guide rod 3071 to limit the movement range of the mounting plate 305. The right side of each of the two limiting rings 3072 is fixedly connected to the connecting block 3073. The connecting block 3073 connects the limiting ring 3072 to the right side of the inner wall of the sedimentation tank 1. The right side of the two connecting blocks 3073 is fixedly connected to the front and rear ends of the right side of the inner wall of the sedimentation tank 1, so that the limiting component 307 is stably connected to the inner wall of the sedimentation tank 1 to ensure the limiting effect.

[0043] Specifically, wastewater is filtered through filter screen 301 to prevent solid sediment from flowing out with the water. However, over time, sediment tends to accumulate at filter screen 301, affecting drainage efficiency and thoroughness. At this point, cleaning mechanism 3 comes into play. Servo motor 303 starts, driving lead screw 304 to rotate. Since lead screw 304 is threadedly connected to mounting plate 305, mounting plate 305 moves up and down along lead screw 304. The cleaning hanging plate 306 fixed on the right side of mounting plate 305 moves accordingly. During the movement, cleaning hanging plate 306 scrapes the surface of filter screen 301, scraping off the sediment accumulated on filter screen 301, causing the sediment to fall into sedimentation tank 1. At the bottom, to prevent continuous clogging of the filter screen 301, thus ensuring smooth and thorough drainage, the limiting component 307 stabilizes the movement of the mounting plate 305. Two guide rods 3071 are fixed to the top of the mounting plate 305, and the limiting ring 3072 can slide on the guide rods 3071. The limiting ring 3072 is connected to the right side of the inner wall of the sedimentation tank 1 through the connecting block 3073. This structure ensures that the mounting plate 305 remains stable during up and down movement and will not shift, so that the cleaning hanging plate 306 can accurately and stably clean the filter screen 301, effectively solving the problem of incomplete drainage caused by sediment accumulation and ensuring the normal operation of the drainage function of the sedimentation tank 1.

[0044] Reference Figure 1 , Figure 2 and Figure 4 The sedimentation tank 1 has a guide channel 7 at the bottom of its inner wall. The guide channel 7 guides the sludge settled at the bottom of the tank to flow. A sludge collection hopper 8 is fixedly connected to the bottom of the inner wall of the guide channel 7. The sludge collection hopper 8 is used to collect the sludge collected from the guide channel 7 for centralized treatment. Limiting blocks 9 are fixedly connected to the top of the two guide rods 3071. The limiting blocks 9 restrict the upward movement range of the limiting ring 3072 on the guide rods 3071. Buffer pads 10 are fixedly connected to the bottom of the two limiting blocks 9. Buffer pads 10 act as a buffer when the limiting ring 3072 moves upward and approaches the limiting blocks 9. The two buffer pads 10 have their bottoms abutting against the tops of the corresponding limit rings 3072 to reduce the impact of collisions. The bottoms of the two buffer pads 10 are respectively attached to the tops of the limit rings 3072 to ensure that the buffer pads 10 can effectively buffer the impact of the limit rings 3072. The tops of the two buffer pads 11 are fixedly connected to the front and rear sides of the top of the mounting plate 305. The buffer pads 11 play a buffering role when the limit rings 3072 move downward and approach the mounting plate 305. The tops of the two buffer pads 11 are respectively attached to the bottoms of the corresponding limit rings 3072 to ensure that the buffer pads 11 can accurately buffer the downward impact of the limit rings 3072.

[0045] Specifically, the guide channel 7 can guide the flow of sludge settled at the bottom of the pool, the sludge collection hopper 8 is used to collect the sludge that converges from the guide channel 7 for centralized treatment, the limiting block 9 restricts the upward movement range of the limiting ring 3072 on the guide rod 3071, the buffer pad 10 plays a buffering role when the limiting ring 3072 moves upward and approaches the limiting block 9 to reduce collision impact, and the buffer pad 2 11 plays a buffering role when the limiting ring 3072 moves downward and approaches the mounting plate 305.

[0046] Working Principle: When it is necessary to clean the solid particles accumulated at the bottom of sedimentation tank 1, the drainage mechanism 2 is activated. The two servo motors 402 in the drive assembly 4 are started, driving the lead screw 403 to rotate. Since the lead screw 403 is threadedly connected to the inner wall of the slider 206, and the slider 206 is fixedly connected to the movable sealing baffle 204, the movable sealing baffle 204 moves up and down within the sealing groove 203. By controlling the rotation of the servo motors 402, the height of the movable drain outlet 207 can be adjusted. This prevents excessive water retention at the bottom of the tank due to an overly high drain outlet, thus avoiding problems caused by improper drain outlet settings, such as excessive water retention and sediment overflow. This improves cleaning efficiency and... In effect, when staff need to enter the sedimentation tank 1 for cleaning operations, they can use the climbing component 5. The climbing ladder 501 is fixed to the bottom left end of the inner wall of the sedimentation tank 1. Staff can climb to the required position through the climbing ladder 501. The handrail 503 at the top provides safety for the staff. After cleaning is completed, the flushing component 6 starts to work. The water supply tank 604 stores the cleaning water and delivers the water to the nozzle 602 through the water supply pipe 603. The nozzle 602 can slide flexibly on the top of the mounting frame 601, which can thoroughly clean all parts of the inner wall of the sedimentation tank 1, ensuring that the inside of the sedimentation tank 1 is clean and ready for the next sewage treatment. The cleaning mechanism 3 can perform targeted cleaning on the right side of the inner wall of the sedimentation tank 1. In conjunction with the overall drainage, climbing and cleaning process, it can ensure the efficient operation of the sedimentation tank 1 and improve the energy saving and emission reduction effect and work efficiency of the entire sewage treatment system.

[0047] Furthermore, when sedimentation tank 1 is draining, the wastewater is filtered through filter screen 301 to prevent solid sediment from flowing out with the water. However, over time, sediment tends to accumulate at filter screen 301, affecting drainage efficiency and thoroughness. At this time, cleaning mechanism 3 comes into play. Servo motor 303 starts, driving lead screw 304 to rotate. Since lead screw 304 is threadedly connected to mounting plate 305, mounting plate 305 moves up and down along lead screw 304. The cleaning hanging plate 306 fixed on the right side of mounting plate 305 moves accordingly. During the movement, cleaning hanging plate 306 scrapes the surface of filter screen 301, scraping off the sediment accumulated on filter screen 301, causing the sediment to fall off. The sediment falls to the bottom of the sedimentation tank 1, preventing it from continuously clogging the filter screen 301, thus ensuring smooth and thorough drainage. The limiting component 307 stabilizes the movement of the mounting plate 305. Two guide rods 3071 are fixed to the top of the mounting plate 305, and the limiting ring 3072 can slide on the guide rods 3071. The limiting ring 3072 is connected to the right side of the inner wall of the sedimentation tank 1 through the connecting block 3073.
