Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment equipment technology, and in particular to a high-efficiency water distribution device for an anaerobic reactor. Background Technology

[0002] Anaerobic reactors are widely used in the treatment of municipal sewage, industrial wastewater, and organic waste. Their operating efficiency largely depends on the effectiveness of the influent distribution system. A good distribution system ensures uniform water flow, avoids short-circuiting or dead zones, and thus promotes the stable growth and efficient metabolism of anaerobic bacteria. Maintaining appropriate hydraulic retention time and reactor internal load during the anaerobic reaction process is crucial for ensuring stable system operation and improving pollutant removal rates.

[0003] Currently, commonly used water distribution systems typically employ fixed distribution pipes, perforated distribution plates, or rotating nozzles. The distribution pipes have several openings, allowing water to be evenly distributed to different areas within the reactor via gravity or pump pressure. Some systems also include a rotating arm, which enables dynamic water distribution through rotation, thereby expanding the coverage area. These devices are relatively simple in structure, easy to install, and can meet basic water distribution requirements to a certain extent, and are widely used in industrial applications.

[0004] However, existing water distribution devices often suffer from insufficient flow regulation capabilities during the water distribution process, making it difficult to flexibly adjust the influent flow rate according to the actual operating conditions of the reactor. When the influent flow rate is too high or too low, it can easily lead to fluctuations in the hydraulic load of the reactor, resulting in problems such as system instability and decreased reaction efficiency. At the same time, the difficulty in reasonably controlling the residence time of water in the reactor may affect the metabolic environment of anaerobic bacteria, reducing the treatment efficiency of pollutants. This water distribution method, which lacks flow control, is no longer able to meet the current demand for efficient and stable wastewater treatment systems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a high-efficiency water distribution device for anaerobic reactors, which aims to improve the insufficient flow regulation capacity of existing water distribution devices. When the influent flow rate is too large or too small, it is easy to cause fluctuations in the hydraulic load of the reactor, which in turn leads to unstable system operation and reduced reaction efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-efficiency water distribution device for an anaerobic reactor, comprising a base, a mixing tank fixedly connected to the upper surface of the base, an inlet pipe fixedly connected to the outer wall of the mixing tank, and an adjustment component provided inside the inlet pipe;

[0007] The adjusting assembly includes a sealing plate one and a sealing plate two, which are disposed inside the water inlet pipe. A sealing groove is provided inside the water inlet pipe. Sealing strips are provided on the outer walls of both sealing plates one and two, and the sealing strips are disposed inside the sealing groove. A rotating shaft one is rotatably connected inside sealing plates one and two. Connecting block two and connecting block three are rotatably connected to the outer wall of rotating shaft one. A sleeve is fixedly connected to the outer wall of connecting block two. A slide rail is fixedly connected to the outer wall of the water inlet pipe. A slider is slidably connected inside the slide rail. One end of the outer wall of connecting block two and connecting block three is disposed inside the slider.

[0008] Furthermore, a connecting block 1 is fixedly connected to the upper surface of the mixing tank, a filter cover is slidably connected to the inner wall of the connecting block 1, a fixing plate 2 is fixedly connected to the outer wall of the filter cover, an elastic block is fixedly connected to the outer wall of the fixing plate 2, a fixing ring is fixedly connected to the upper surface of the connecting block 1, a fixing plate 1 is fixedly connected to the upper surface of the fixing ring, a fixing block is fixedly connected to the upper surface of the fixing plate 1, a spring is provided inside the fixing block, a sliding plate is fixedly connected to one end of the spring, and a fixing ball is fixedly connected to the outer wall of the sliding plate.

[0009] Furthermore, a distribution pipe is fixedly connected to the outer wall of the connecting block, and a main water distribution pipe is fixedly connected inside the filter cover.

[0010] Furthermore, a second rotating shaft is fixedly connected to the inner wall of the mixing tank, and a guide plate is fixedly connected to the outer wall of the second rotating shaft.

[0011] Furthermore, a filter plate is fixedly connected to the inner wall of the mixing tank, and the main water distribution pipe is fixedly connected inside the mixing tank.

[0012] Furthermore, one end of the spring is fixedly connected to the inner wall of the fixed block, and the sliding plate is slidably connected inside the fixed block.

[0013] Furthermore, the elastic block is slidably connected to the outer wall of the fixed ball, and a reinforcing ring is fixedly connected to the outer wall of the water inlet pipe.

[0014] Furthermore, the inner wall of the fixed ring is slidably connected to the outer wall of the filter cover, and the outer wall of the guide plate is rotatably connected to the bottom of the inner wall of the mixing tank.

[0015] This utility model has the following beneficial effects:

[0016] In this invention, an adjustable flow rate structure is provided inside the inlet pipe, mainly including a slide rail, a slider, a connecting block, and a sealing plate. The slider can slide along the slide rail, driving the connecting block to rotate on the outer wall of the rotating shaft, thereby adjusting the angle of the sealing plate. A sealing strip is provided on the outer side of the sealing plate, which can cooperate with the sealing groove on the inner wall of the inlet pipe to achieve sealing control. By adjusting the angle of the sealing plate, the opening area of ​​the water flow channel can be precisely adjusted, thereby achieving control of the inlet flow rate. This structure can flexibly adjust the inlet rate according to the operating requirements, ensuring stable hydraulic conditions in the reactor and improving the continuity and efficiency of system operation.

[0017] In this invention, a multi-stage filtration system is constructed by installing a filter cover and filter plate inside the mixing tank.

The filter cover is equipped with a fixing plate and elastic block, and the connecting block is equipped with a fixing ring and quick-release structure. The internal components include springs, sliding plates, and fixing balls, which enable quick assembly and disassembly of the filter cover. This design allows operators to clean or replace the filter screen through the inspection cover without disassembling the entire unit, thus improving maintenance efficiency and equipment reliability.

[0028] Reference Figures 1-5A connecting block 8 is fixedly connected to the upper surface of the mixing tank 2. A filter cover 7 is slidably connected to the inner wall of the connecting block 8. The filter cover 7 serves as a second-stage filtration structure, working in conjunction with the filter cover 8 to further trap smaller particles of impurities, improve filtration accuracy, ensure cleaner water entering the water distribution pipe, and reduce the risk of clogging. A fixing plate 12 is fixedly connected to the outer wall of the filter cover 7. An elastic block 10 is fixedly connected to the outer wall of the fixing plate 12. A fixing ring 25 is fixedly connected to the upper surface of the connecting block 8. A fixing plate 11 is fixedly connected to the upper surface of the fixing ring 25. A fixing block 9 is fixedly connected to the upper surface of the fixing plate 11. A spring 27 is installed inside the fixing block 9. The spring 27 mainly compresses the fixing ball 24, allowing the elastic block 10 to be inserted into it. A sliding plate 23 is fixedly connected to one end of the spring 27. A fixing ball 24 is fixedly connected to the outer wall of the sliding plate 23. A distribution pipe 6 is fixedly connected to the outer wall of the connecting block 8.

The inner wall of the mixing tank 2 is fixedly connected to the rotating shaft 26. The outer wall of the rotating shaft 26 is fixedly connected to the guide plate 13. The inner wall of the mixing tank 2 is fixedly connected to the filter plate 14.

The outer wall of the guide plate 13 rotates to connect to the bottom of the inner wall of the mixing tank 2.

[0029] Working principle: When a high-efficiency water distribution device for an anaerobic reactor is needed, the raw water first enters the inlet chamber through the inlet pipe 3. Under the guidance of the guide plate 13 inside the device, it forms a directional or rotating flow, effectively reducing the direct impact of the water flow on the filter plate 14. At the same time, larger particles and impurities in the water settle down along the inner wall to the dirt collection chamber, while the cleaner water enters the filter cover 7 through the main water distribution pipe 15. The filter cover 7 has a porous structure, which can intercept suspended particles and impurities in the water and discharge them through the distribution pipe 6. When the flow rate needs to be adjusted, an adjustment component is installed inside the inlet pipe 3. By sliding the slider 21 inside the slide rail 22, the connecting block 2 18 is driven to connect with the connecting... Block 3 19 rotates on the outer wall of the rotating shaft 20. Connecting block 2 18 is connected to the sleeve 29 on the outer wall of the sealing plate 5, which drives the sealing plate 5 to rotate. Connecting block 3 19 drives the rotating shaft 20 to rotate, and at the same time drives the sealing plate 2 16 to rotate along the rotating shaft 20. At the same time, the outer walls of the sealing plate 5 and the sealing plate 2 16 are also provided with sealing strips 17, which match the sealing groove 28 inside the water inlet pipe 3 to achieve structural sealing. Adjusting the opening of the water flow channel can achieve flow regulation, which helps to maintain a stable hydraulic load in the anaerobic reactor, avoid system disturbance or efficiency reduction caused by flow fluctuations, and can adjust the water retention time to ensure that the reaction is carried out under suitable conditions, thereby improving treatment efficiency and operational stability.

[0030] In addition, the raw water enters the mixing tank 2 for preliminary water distribution treatment. The mixing tank 2 is equipped with a filter cover 7, a filter plate 14, and a main water distribution pipe 15, which can effectively intercept impurities such as mud, suspended particles, and flocs in the liquid, preventing them from entering the main water distribution system and causing blockage or wear on equipment components such as the guide plate 13 and the distribution pipe 6. At the same time, the outer wall of the filter cover 7 is equipped with a fixing plate 12 and an elastic block 10. The elastic block 10 is made of elastic metal. The upper surface of the connecting block 8 has a fixing ring 25 and a fixing block 9. The fixing block 9 is equipped with a spring 27, a sliding plate 23, and a fixing ball 24. Through their cooperation, the filter cover 7 can be quickly fixed, improving filtration efficiency and filter screen life. When the filter screen is clogged or needs to be replaced, the operator can pull out or replace the filter screen by opening the inspection cover on the top or side of the device without disassembling the entire equipment.
