Description

Technical Field

[0001] This invention relates to the field of rainwater treatment and sewage treatment technology, specifically to an initial rainwater interception device based on Taiji flow technology. Background Technology

[0002] In urban stormwater drainage systems, initial rainwater often carries large amounts of pollutants, such as silt, garbage, and oil. Direct discharge of these pollutants can cause serious pollution to aquatic environments. Traditional stormwater interception devices have many shortcomings, such as low interception efficiency, inconvenient cleaning, and unsatisfactory water flow control. There is an urgent need for a more efficient and easy-to-operate and maintain interception device to improve the current situation.

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

[0004] However, the above solution uses a physical filtration structure for filtration. In areas with a high level of dirt, the trap basket can collect a lot of dirt in a short time. If the dirt on the trap basket is not cleaned, it may cause a decrease in filtration efficiency or even blockage. Summary of the Invention

[0005] The present invention aims to at least partially solve one of the technical problems in the aforementioned related technologies.

[0006] Therefore, the present invention specifically provides the following technical solution:

[0007] A rainwater interception device based on Taiji flow technology includes a cylindrical body. A mirror-symmetrical inlet pipe and outlet pipe are fixedly installed on the top two sides of the outer wall of the cylindrical body. A fan-shaped cavity is fixedly installed on the top two sides of the inner wall of the cylindrical body. The inner cavity of the two fan-shaped cavities is connected to the inlet pipe and the outlet pipe, respectively. Two openings with opposite directions are opened on one side of the bottom end of the two fan-shaped cavities along the circumferential direction.

[0008] Preferably, a perforated baffle is provided at the top of the cylinder.

[0009] Preferably, the two sector-shaped cavities are connected by an arc-shaped cavity.

[0010] Preferably, a settling plate is provided at the bottom of the inner cavity of the cylinder. The settling plate is a square plate, and side plates are installed at the midpoints of the four sides of the settling plate via a rotating structure. A sliding rod is fixedly installed on the settling plate, and a lead screw is rotatably installed on the settling plate. A lead screw nut is threaded onto the lead screw, and a sliding hole is provided on the lead screw nut for sliding onto the sliding rod. A traction rope is fixedly connected to the side plate, and the top end of the traction rope is fixedly connected to the lead screw nut.

[0011] Preferably, the hollow baffle has a circular hole, a circular plate is fixedly installed in the circular hole, a rotating column is fixedly installed at the top of the lead screw, the circular plate has a rotating hole to rotatably fit the rotating column, and the top of the sliding rod is fixedly installed on the circular plate.

[0012] Preferably, the rotating column has a transmission groove and a transmission plate, one end of which engages with the transmission groove.

[0013] Preferably, a handle is rotatably mounted on the end of the transmission plate away from the rotating column.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] The Tai Chi Flow technology used in this device guides rainwater along a specific and relatively stable path by setting fan-shaped cavities and connecting arc-shaped cavities at the top of the inner wall of the cylinder, avoiding adverse conditions such as water flow collision. Utilizing the principle of gravity sedimentation, pollutants such as silt can settle in the sedimentation zone, significantly improving the overall interception capacity for various types of pollutants. This method can settle a large amount of pollutants, and because there is no physical interception structure, there is no need to clean the physical interception structure. The bottom of the cylinder is set to receive sediment, without obstructing the water flow above, without affecting the filtration efficiency, and can hold more pollutants compared to material interception structures.

[0027] The initial rainwater interception device based on Taiji flow technology works by using specially designed channels and structures to create a rotating flow resembling a Taiji symbol, generating centrifugal force and turbulence to achieve initial solid-liquid separation of pollutants and water. In rainwater treatment, it can be applied to urban road rainwater collection and treatment, intercepting road pollutants, reducing the burden of subsequent treatment, and allowing for the recycling of treated rainwater. In residential rainwater collection and utilization, it improves the safety of rainwater use and provides a clean water source for the community. In wastewater treatment, it is used for pretreatment in wastewater treatment plants, reducing the load on subsequent processes and minimizing equipment wear. It is also suitable for decentralized wastewater treatment facilities in remote areas or small communities, as its simple structure, small footprint, and low cost effectively improve local water quality.

[0028] Example 1

[0029] like Figures 1 to 4 As shown, many traditional devices rely solely on simple filters or single sedimentation structures for pollution interception, such as common grid filters. These can only intercept larger floating objects and are ineffective at intercepting fine particles like silt and dissolved pollutants like oil. This device, however, includes a cylindrical body 1. Mirror-symmetrical inlet pipes 2 and 3 are fixedly installed on the top two sides of the outer wall of the cylindrical body 1. Fan-shaped cavities 4 are fixedly installed on the top two sides of the inner wall of the cylindrical body 1. The inner cavities of the two fan-shaped cavities 4 are connected to the inlet pipes 2 and 3, respectively. Two openings 5 ​​in opposite directions are formed along the circumference of one side of the bottom of each fan-shaped cavity 4. A perforated baffle 6 is installed at the top of the cylindrical body 1. The two fan-shaped cavities 4 are connected by an arc-shaped cavity 7, thereby improving the overall connection strength of the two fan-shaped cavities 4.

[0030] Some existing devices lack precise planning of the water flow path when rainwater enters and exits, often resulting in turbulent flow. This leads to poor sedimentation of pollutants and may affect the overall drainage efficiency of the device. The Taiji Flow technology used in this device cleverly guides rainwater along a specific and relatively stable path by incorporating 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. Utilizing the principle of gravity settling, pollutants such as silt can settle in the sedimentation zone (i.e., the lower part of the cylinder 1), significantly improving the overall interception capacity for various types of pollutants. This is an optimization and expansion based on traditional interception concepts, combined with a more rational structural layout to achieve a more efficient interception effect.

[0031] The Tai Chi flow technology works as follows: fluid enters from the inlet pipe 2 and flows into the right-side fan-shaped cavity 4, while exiting from the left-side opening 5 of the fan-shaped cavity 4. The fluid flows counter-clockwise within the cylinder 1, gradually rising until it surpasses the left-side opening 5. There, the counter-clockwise flowing fluid converges in the center of the cylinder 1, and then flows clockwise towards the edge of the cylinder wall and out through the right-side opening 5 of the left-side fan-shaped cavity 4, creating two opposing flow directions, resembling the flow of a Tai Chi symbol. A low-energy swirling zone is established in the lower middle part of the lower cylinder 1. Oils, floating debris, etc., rise to the surface, while sediments directly enter the bottom of the cylinder 1. The treated water flows in a spiral pattern opposite to the inlet direction through a submerged drainage trough, ensuring the longest possible residence time for pollutants between the inlet and outlet. This ensures the spiral water flow remains within the cylinder 1 cavity long enough for optimal swirling separation. Wastewater flows quickly through the interior of the cylinder 1 cavity, reducing turbulence and effectively preventing settled debris from being carried away by the water flow again. The minimal internal structure of the cylinder 1 cavity allows the incoming water to flow directly out of the outlet trough, reducing external water flow.

[0032] Example 2

[0033] Based on Embodiment 1, a settling plate 8 is also provided at the bottom of the inner cavity of the cylinder 1. The settling plate 8 is a square plate, and side plates 10 are installed at the midpoints of the four sides of the settling plate 8 through a rotating structure 9. A sliding rod 11 is fixedly installed on the settling plate 8, and a lead screw 12 is rotatably installed on the settling plate 8. A lead screw nut 13 is threaded onto the lead screw nut 12, and a sliding hole 14 is provided on the lead screw nut 13 for sliding onto the sliding rod 11. A traction rope 15 is fixedly connected to the side plate 10, and the top end of the traction rope 15 is fixedly connected to the lead screw nut 13. A circular hole is provided on the hollow baffle 6, and a circular plate 16 is fixedly installed in the circular hole. A rotating column 17 is fixedly installed on the top end of the lead screw 12, and a rotating hole is provided on the circular plate 16 to rotatably engage the rotating column 17. The top end of the sliding rod 11 is fixedly installed 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. One end of the transmission plate 19 engages with the transmission groove 18. A handle 20 is rotatably mounted on the end of the transmission plate 19 away from the rotating column 17.

[0034] Since a sedimentation zone is formed at the bottom of the cylinder 1, and this zone needs to be cleaned periodically after accumulating a large amount of debris, the cleaning process is as follows: by holding the handle 20, the transmission plate 19 is rotated through the handle 20. The transmission plate 19 then engages with the transmission groove 18 to drive the rotating column 17, thereby causing the rotating column 17 to rotate the lead screw 12. Because the rotating column 17 is supported by the rotation of the circular plate 16, it can rotate around its central axis. Correspondingly, since the hollow baffle 6 has low strength, the circular plate 16 is fixedly installed to strengthen the structural rigidity. Thus, the circular hole of the circular plate 16 can support the rotating column 17 to rotate around its central axis, thereby driving the lead screw. 12. Rotation: Since the lead screw nut 13 is slidably sleeved on the sliding rod 11 through the sliding hole 14, the lead screw nut 13 moves longitudinally reciprocally through the threaded engagement. When the lead screw nut 13 slides upward, the lead screw nut 13 can pull the outer side of the side plate 10 through the traction rope 15, thereby causing the side plate 10 to flip inward. When the side plate 10 is perpendicular to the sedimentation plate 8, the lead 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. The large circular sedimentation plate structure composed of the side plate 10 and the sedimentation plate 8 can be folded and taken out. During the process of the side plate 10 flipping inward, the side plate 10 flips the surface debris inward, thereby storing it.
