Description

Technical Field

[0001] The utility model relates to the technical field of rainwater and sewage diversion interception wells, in particular to a rainwater and sewage diversion interception well. Background Art

[0002] Municipal sewage interception wells are a crucial ancillary structure in combined sewer systems. Their primary function is to divert dry-flow sewage and initial rainwater into the sewage interceptor pipe, thereby preventing further pollution of urban water bodies. During the rainy season, sewage interception wells must ensure a consistent flow rate to avoid increasing the load on municipal sewage treatment plants. Furthermore, they must ensure that rainwater in the combined sewer drains smoothly within the designed flow range.

[0003] Currently, interception wells on the market are used to divert rainwater and sewage, and generally rely on liquid level sensors or timers to detect or record the amount of water in the interception well, thereby controlling the opening and closing status of the valve at the sewage interception outlet to achieve rainwater and sewage diversion. However, this method has some limitations. Since the ultimate goal of rainwater and sewage diversion is to reduce the flow of sewage into natural water bodies, liquid level sensors or timers can only detect the amount of water in the interception well, but cannot determine the water quality in the interception well. Therefore, diversion control can only be based on water quantity rather than water quality. In some cases, sewage may still flow into natural water bodies, thus failing to fully achieve the purpose of rainwater and sewage diversion.

[0004] How to solve the above problems is the research focus of this program. Utility Model Content

[0005] In order to achieve the above-mentioned purpose of the utility model and address the above-mentioned technical problems, the utility model provides a rainwater and sewage diversion interception well.

[0006] The technical solution is as follows: it includes a diverter box and a separation mechanism;

[0007] The diverter box is arranged in the well, and the separation mechanism is arranged in the diverter box for separating impurities in the sewage;

[0008] The separation mechanism includes: a filter plate and a collection tank;

[0009] The filter plate is connected to the inner wall of the diversion box and is arranged at an angle. Several evenly distributed small holes are formed on the surface of the filter plate. A through hole is formed at one end of the bottom of the filter plate. The collection tank is connected to the through hole to collect impurities. This design can effectively separate and collect impurities in sewage. Impurities are filtered through the small holes on the filter plate and collected in the collection tank for subsequent processing.

[0010] The separation mechanism further comprises: a reciprocating screw, a movable block and a scraper;

[0011] A housing is provided on one side of the diverter box. Both ends of the reciprocating screw are rotatably connected to the inner wall of the housing via bearings, and the inclination angle is the same as the inclination angle of the filter plate. The movable block is threadedly connected to the outer wall of the reciprocating screw. An inclined chute is provided on the partition between the diverter box and the housing. The other end of the movable block movably passes through the chute and extends into the interior of the diverter box. The scraper is provided on the upper surface of the filter plate, and one end of the scraper is connected to the extended end of the movable block. The reciprocating motion of the reciprocating screw drives the movable block to move, thereby pushing the scraper to move on the filter plate, thereby scraping impurities on the filter plate and pushing the impurities into the collection tank, thereby improving the efficiency of impurity collection.

[0012] The scraper has a triangular longitudinal cross-section, with the bottom surface of the scraper fitting against the upper surface of the filter plate. This triangular scraper design more effectively conforms to the inclined surface of the filter plate, ensuring that impurities are completely scraped into the collection trough, preventing them from backtracking or scattering, and improving collection accuracy.

[0013] A water guide plate is connected to the upper portion of the inner wall of the box body. Two water guide plates are provided. An opening is formed between the two water guide plates. The upper surfaces of the two water guide plates are inclined from one end toward the opening.

[0014] The opening is arranged corresponding to the top of the filter plate. The design of the water guide plate can guide the water flow so that the water flow can more effectively impact the filter plate after passing through the water guide plate, helping to separate impurities from water. At the same time, the design of the opening allows the water flow to pass smoothly, reducing the interference of the water flow on the collection of impurities.

[0015] A transmission mechanism is provided below the openings of the two water guide plates, and the transmission mechanism comprises: a rotating rod, a first helical gear, a second helical gear and a turbine;

[0016] The two ends of the rotating rod are rotatably connected to the inner wall of the diverter box via bearings, and the rotating rod is located below the openings of the two water guide plates. The turbine is fixedly mounted on the outer wall of the rotating rod, and one end of the rotating rod moves through the diverter box and extends into the interior of the box. The first helical gear is fixedly mounted on the extended end of the rotating rod and is coaxially fixedly connected to the rotating rod. The second helical gear is fixedly mounted on the outer wall of the reciprocating screw, and the first and second helical gears are meshed. The transmission mechanism is designed to utilize the power of the water flow to drive the turbine, which in turn drives the rotating rod and the helical gear to rotate, realizing the reciprocating motion of the reciprocating screw, thereby driving the scraper to move, realizing an automated impurity collection process, reducing manual intervention, and improving the system's degree of automation.

[0017] The first and second helical gears are 45-degree helical gears, and a drainage hole is provided at the bottom of one inner wall of the diverter box. The 45-degree helical gear design improves transmission efficiency, making the reciprocating screw's motion smoother and more efficient. The drainage hole allows filtered water to drain smoothly, reducing water accumulation in the interception well and maintaining its normal operation.

[0018] The beneficial effects of the technical solution provided by the embodiment of the utility model are as follows: the solution provides a rainwater and sewage diversion interception well, which separates impurities by using a filter plate provided in the diversion box through a separation mechanism, and collects impurities through a collection trough on one inclined side. At the same time, the reciprocating screw is rotated to drive the movable block to move, thereby pushing the scraper connected to one side thereof to move, thereby pushing the impurities on the filter plate and dropping them into the collection trough. The triangular scraper can prevent the impurities from falling to the left side of the scraper, thereby avoiding affecting the collection of impurities. The advantages are mainly reflected in the following aspects:

[0019] Efficient separation of impurities: The utility model can effectively separate impurities in sewage by arranging an inclined filter plate in the diversion box and opening evenly distributed small holes on the surface of the filter plate;

[0020] Automatic collection of impurities: The through-holes at the bottom of the filter plate are connected to the collection tank, which can automatically collect the separated impurities, reducing the need for manual cleaning;

[0021] Mechanically driven impurity collection: Through the coordinated use of reciprocating screw, movable block and scraper, the mechanically driven impurity collection process is realized, which improves the efficiency of separation and collection;

[0022] Prevent impurities from going back: The triangular design of the scraper can prevent impurities from going back to the left side of the filter plate, ensuring that the impurities fall smoothly into the collection tank;

[0023] Utilizing water flow power: The transmission mechanism is designed to utilize the power of water flow to drive the turbine, which in turn drives the entire impurity collection mechanism, achieving efficient energy utilization;

[0024] Compact structure, easy to install and maintain: The entire interception well is designed with a compact structure, which is easy to install in the existing well and also convenient for daily maintenance and cleaning;

[0025] Improve sewage treatment efficiency: Through more accurate rainwater and sewage separation, the burden of rainwater treatment on sewage treatment plants is reduced, and the efficiency and effectiveness of sewage treatment are improved;

[0026] Reduce environmental pollution: effectively reduce the pollution of sewage to natural water bodies and protect the urban water environment;

[0027] Through the above design, the rainwater and sewage diversion interception well of the utility model can realize rainwater and sewage diversion more efficiently and accurately, which helps to improve the performance of the urban drainage system, reduce environmental pollution, and improve the efficiency of sewage treatment.
