Description

Technical Field

[0001] The invention relates to the technical field of rainwater treatment and sewage treatment, and in particular to an initial rainwater sewage interception device based on Tai Chi flow technology. Background Art

[0002] In the urban rainwater drainage system, the initial rainwater often carries a large amount of pollutants, such as mud, garbage, oil, etc. If discharged directly, it will cause serious pollution to the water environment. Traditional rainwater sewage interception devices have many shortcomings, such as low sewage interception efficiency, inconvenient cleaning, and unsatisfactory water flow control. There is an urgent need for an efficient and easy-to-operate and maintain sewage interception device to improve the current situation.

[0003] For example, the invention patent application with application number CN202310792173.0 discloses a rainwater outlet sewage interception device, including a hook, a hanging basket bracket, and a sewage interception hanging basket. The sewage interception hanging basket is arranged on the hanging basket bracket, and the hook is arranged on the top of the hanging basket bracket. The hanging basket bracket can be hung on the well ring through the hook, and the sewage interception hanging basket is provided with leakage holes around it. The invention provides a rainwater outlet sewage interception device that reduces sewage cleaning time and improves work efficiency.

[0004] However, the above scheme uses a physical filtering structure to filter. In areas where the presence of dirt is high, the intercepting basket can collect more dirt in a shorter time. If the dirt on the intercepting basket is not cleaned at this time, the filtration efficiency may decrease or even become blocked. Summary of the invention

[0005] The present invention aims to solve one of the technical problems in the above-mentioned related art at least to a certain extent.

[0006] To this end, the present invention specifically provides the following technical solutions: An initial rainwater sewage interception device based on Tai Chi flow technology includes a cylinder, and a mirror-symmetrical water inlet pipe and a water outlet pipe are fixedly arranged on both sides of the top of the outer wall of the cylinder, and fan-shaped cavities are fixedly arranged on both sides of the top of the inner wall of the cylinder, and the inner cavities of the two fan-shaped cavities are respectively connected to the water inlet pipe and the water outlet pipe, and two openings in opposite directions are respectively opened on one side of the bottom end of the two fan-shaped cavities along the circumferential direction.

[0007] Preferably, a hollow baffle is provided at the top of the cylinder.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The Tai Chi flow technology used in this device guides rainwater to flow along a specific, relatively stable path by setting a fan-shaped cavity at the top of the inner wall of the cylinder and connecting them with an arc-shaped cavity, avoiding adverse conditions such as water flow collision. By using the principle of gravity sedimentation, pollutants such as silt can be precipitated in the sedimentation area, greatly improving the overall interception capacity of various types of pollutants.

[0021] The initial rainwater interception device based on Tai Chi flow technology has a technical principle of using specially designed flow channels and structures to allow the water flow to form a rotating flow similar to the Tai Chi pattern, generating centrifugal force and turbulence effects, thereby achieving the initial solid-liquid separation of pollutants and water. In the field of rainwater treatment, it can be used for the collection and treatment of rainwater on urban roads, intercepting road pollutants, and reducing the burden of subsequent treatment. The treated rainwater can also be recycled; in the collection and utilization of rainwater in residential areas, it can improve the safety of rainwater utilization and provide clean water sources for the community. In the field of sewage treatment, it is used for pretreatment in sewage treatment plants to reduce subsequent process loads and equipment wear; it is also suitable for decentralized sewage treatment facilities in remote areas or small communities. Because of its simple structure, small footprint and low cost, it can effectively improve the quality of the local water environment.

[0022] Embodiment 1 like Figures 1 to 4 As shown, many traditional devices rely only on simple filters or single sedimentation structures to intercept pollutants. For example, the common grid filter can only intercept larger floating objects, and has poor interception effects on fine particles such as mud and sand and soluble pollutants such as oil. The present device includes a cylinder 1, and the top of the outer wall of the cylinder 1 is fixed with a mirror-symmetrical water inlet pipe 2 and a water outlet pipe 3 on both sides, and the top of the inner wall of the cylinder 1 is fixed with fan-shaped cavities 4 on both sides. The inner cavities of the two fan-shaped cavities 4 are connected to the water inlet pipe 2 and the water outlet pipe 3 respectively, and two openings 5 ​​in opposite directions are respectively opened on one side of the bottom end of the two fan-shaped cavities 4 along the circumferential direction. A hollow baffle 6 is provided at the top of the cylinder 1. The two fan-shaped cavities 4 are connected by an arc cavity 7, thereby improving the overall connection strength of the two fan-shaped cavities 4.

[0023] Some existing devices lack detailed planning of the water flow path when rainwater enters and flows out, which often easily causes water turbulence, resulting in the inability of pollutants to settle well, and may also affect the overall drainage efficiency of the device. The Tai Chi flow technology used in this device cleverly guides rainwater to flow along a specific and relatively stable path by setting a fan-shaped cavity 4 and an arc-shaped cavity 7 connecting them at the top of the inner wall of the cylinder 1, avoiding adverse conditions such as water flow collision. By utilizing the principle of gravity sedimentation, pollutants such as silt can be precipitated in the sedimentation area (i.e., the lower part of the cylinder 1), greatly improving the overall interception capacity of various types of pollutants. This is an optimization and expansion based on the traditional concept of interception, combined with a more reasonable structural layout to achieve a more efficient interception effect.

[0024] Tai Chi flow technology is specifically that when the fluid enters from the water inlet pipe 2 and then flows into the fan-shaped cavity 4 on the right, and the fluid flows out from the left opening 5 of the fan-shaped cavity 4, the fluid flows counterclockwise in the cylinder 1, and then gradually rises in the cylinder 1 until it is higher than the left opening 5, the counterclockwise flowing fluid converges in the center of the cylinder 1, and the fluid gathered in the center flows clockwise toward the edge of the cylinder wall and flows out of the right opening 5 of the fan-shaped cavity 4 on the left, forming two water flows in the forward and reverse directions, thereby forming a water flow similar to Tai Chi. A low-energy vortex area is established in the middle and lower part of the lower cylinder 1. While grease, floating objects, etc. float to the water surface, sediments directly enter the bottom of the cylinder 1. The treated water flows in a spiral opposite to the water inlet direction through the submerged drainage trough, thereby ensuring that the pollutants have the longest residence time between the inlet and outlet, thereby ensuring that the spiral water flow stays in the cylinder 1 cavity for a long enough time to achieve the best effect of vortex separation. The sewage quickly passes through the inner chamber of the cylinder 1, reducing disturbances and effectively preventing the deposited dirt from being carried away by the water flow again. The internal structure of the cylinder 1 chamber is relatively small, so that the incoming water flow flows directly out of the water outlet trough, reducing external water flow.

[0025] Embodiment 2 On the basis of the first embodiment, a settling plate 8 is also provided at the bottom end of the cylinder 1. The settling plate 8 is a square plate. The midpoints of the four sides of the settling plate 8 are all mounted with side plates 10 through a rotating structure 9. A sliding rod 11 is fixedly mounted on the settling plate 8. A lead screw 12 is rotatably mounted on the settling plate 8. A lead screw nut 13 is threadedly sleeved on the lead screw nut 13. A sliding hole 14 for sliding sleeves on the sliding rod 11 is also provided on the lead screw nut 13. A traction rope 15 is fixedly connected to the side plate 10. The top of the traction rope 15 is fixedly connected to the lead screw nut 13. A circular hole is provided on the hollow baffle 6. A circular plate 16 is fixedly mounted in the circular hole. A rotating column 17 is fixedly mounted on the top of the lead screw 12. The circular plate 16 has a rotating hole for rotatably sleeved the rotating column 17. The top of the sliding rod 11 is fixedly mounted on the circular plate 16. A transmission groove 18 is provided on the rotating column 17, and a transmission plate 19 is provided on the rotating column 17, and one end of the transmission plate 19 is engaged with the transmission groove 18. A handle 20 is rotatably mounted on one end of the transmission plate 19 away from the rotating column 17.

[0026] Since a sedimentation area is formed at the bottom of the cylinder 1, and the sedimentation area needs to be cleaned regularly after collecting a lot of debris, the cleaning process at this time is: by holding the handle 20, the transmission plate 19 is rotated by the handle 20, and then the transmission plate 19 realizes the transmission of the rotating column 17 by engaging with the transmission groove 18, so that the rotating column 17 drives the lead screw 12 to rotate. Since the rotating column 17 is supported by the rotation of the circular plate 16, the rotating column 17 can rotate around its own central axis. Accordingly, since the hollow baffle 6 itself has a low strength, a fixed circular plate 16 is set to enhance the structural rigidity, so that the circular hole of the circular plate 16 can support the rotating column 17 to rotate around its own central axis, thereby driving the lead screw. 12 rotates, since the screw nut 13 is slidably mounted on the sliding rod 11 through the sliding hole 14, the screw nut 13 moves back and forth longitudinally through the threaded cooperation. When the screw nut 13 slides upward, the screw nut 13 can pull the outer side of the side plate 10 through the traction rope 15, so that the side plate 10 flips inward. When the side plate 10 is perpendicular to the sedimentation plate 8, the screw 12 is moved upward as a whole through the existing lifting mechanism or directly, so that the side plate 10 will not interfere with the two fan-shaped cavities 4, and the large circular sedimentation plate structure composed of the side plate 10 and the sedimentation plate 8 can be folded and taken out. In the process of flipping the side plate 10 inward, the side plate 10 flips the debris on the surface inward for storage.
