Description

Technical Field

[0001] This invention belongs to the field of water treatment technology, specifically a hydrocyclone-driven rainwater purification well. Background Technology

[0002] In the initial stages of rainfall, raindrops carry a large amount of pollutants such as dust and exhaust particles from the air as they fall. After landing, the rainwater washes away accumulated garbage, oil, heavy metals, and other pollutants from rooftops, roads, and pipe networks, making the pollution intensity of the initial rainwater much higher than that of the later stages. If this high-concentration initial rainwater is discharged directly into natural water bodies without treatment, it will cause shock pollution to the receiving water bodies and, in severe cases, disrupt the aquatic ecological balance. Therefore, it is necessary to collect and purify the initial rainwater.

[0003] In existing technologies, when treating collected rainwater, the rainwater is first fed into a purification well, and then solid agents such as flocculants are added to the purification well and stirred. This destabilizes the small, non-precipitating suspended particles in the water and causes them to aggregate into large flocs, accelerating sedimentation and thus removing suspended solids from the rainwater.

[0004] However, as sediment continues to form, it accumulates at the bottom of the well, not only reducing the effective volume within the well and causing the actual treatment capacity of the purification well to continuously decrease with prolonged operation, but also, if the bottom sediment is not cleaned for a long time, anaerobic fermentation can easily occur. The resulting bubbles will rise to the surface, carrying impurities and re-polluting the upper clear water, leading to a deterioration of the effluent quality. Furthermore, when it is necessary to clean the sediment at the bottom of the well, it is usually necessary to shut down the machine and use manual or mechanical cleaning methods. This operation is cumbersome, labor-intensive, and the purification well cannot work normally during the cleaning cycle, seriously affecting the continuity and overall efficiency of rainwater treatment. Summary of the Invention

[0022] The beneficial effects of this invention are as follows:

[0023] 1. The present invention discloses a hydrocyclone-type rainwater purification well, which utilizes a rectangular gathering and conveying mechanism to achieve regular and automatic cleaning of sediment at the bottom of the purification well during rainwater treatment. This scheme uses a retractable rectangular barrier to gather sediment towards the center and discharges it directly through auger blades, eliminating the need for downtime cleaning and ensuring continuous operation of rainwater treatment. Furthermore, the real-time discharge of sediments prevents them from accumulating at the bottom of the well and occupying effective volume, maintaining the stable treatment capacity of the purification well. Simultaneously, it eliminates the possibility of anaerobic fermentation and re-contamination of the upper clear water by rising air bubbles carrying impurities due to prolonged sediment residue, ensuring stable effluent quality. The entire cleaning process requires no manual entry into the well, significantly reducing labor intensity and maintenance costs.

[0024] 2. The hydrocyclone-type initial rainwater purification well of this invention utilizes a reset-type synergistic flocculant addition auxiliary component, which allows the flocculant to be uniformly dispersed in fine particles across the entire water surface. This enables simultaneous multi-point, large-area dosing, avoiding the problem of uneven agent distribution caused by a single dosing point, shortening the stirring time required to achieve uniform mixing, and improving treatment efficiency. Simultaneously, because the flocculant is uniformly dispersed, it avoids agent waste caused by excessively high local concentrations and ensures that suspended particles in each area can come into contact with sufficient flocculant for effective destabilization and flocculation, further guaranteeing the purification effect.

[0025] Furthermore, each time the rectangular barrier changes volume, the dosing cylinder moves laterally back and forth within the purification well, passing through multiple locations on the water surface, resulting in a wider and more uniform distribution of the flocculant. Simultaneously, each time the rectangular barrier shrinks and gathers sediment into the conveying cylinder, the dosing cylinder moves precisely below the reagent hopper, collecting a specific amount of flocculant as needed based on the actual purification requirements. When the rectangular barrier repositions and expands, the dosing cylinder returns and evenly distributes the newly collected flocculant. In this way, the sediment discharge and reagent replenishment actions work in tandem, automatically and as needed to replenish flocculant in each cleaning cycle, achieving continuous and efficient reagent dosing.

[0026] 3. The hydrocyclone rainwater purification well of the present invention utilizes a deodorization component. The purified rainwater enters the inner cavity of the filter box from the bottom of the purification well body and flows through the activated carbon adsorption plate for deodorization treatment to remove residual odors in the water, further improving the quality of the effluent and making it more suitable for reuse or discharge in compliance with standards.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Example 1:

[0040] Please refer to Figures 1-9The present invention provides a technical solution: a hydrocyclone-type rainwater purification well, including a purification well body 1 and a hydrocyclone 2. The hydrocyclone 2 is provided with an inlet, an overflow outlet and a bottom outlet. The overflow outlet faces the interior of the purification well body 1. It includes a rectangular gathering and conveying mechanism for collecting sediment at the bottom of the inner cavity of the purification well body 1.

[0041] The rectangular gathering and conveying mechanism includes four traction plates 24 arranged in a matrix. The bottom of the inner wall of the traction plates 24 is rotatably connected to vertically arranged rollers 26. Filter cloth 23 is wound on the rollers 26.

The output end of the motor 14 is fixedly connected to one end of the stirring rod 13 on one side.

[0045] like Figures 5-7 As shown, it includes an adjustment assembly for changing the volume of the rectangular barrier formed by four filter cloths 23;

[0046] The adjustment assembly includes a screw guide module 219 located on one side of the outer wall of the purification well body 1. The screw guide module 219 is equipped with a slider that slides vertically, and the slider is fixedly connected to a rectangular frame 38. Multiple sliding rods 20 are slidably connected to the rectangular frame 38 in the circumferential direction.

A motor 4 29 is fixedly connected to the top of the traction plate 24, and the output end of the motor 4 29 is fixedly connected to one end of a roller 26.

[0047] like Figure 6 As shown, the adjustment component also includes a linkage structure;

[0048] The linkage structure includes a lead screw 22 that is rotatably connected to one side of a rectangular frame 38 along the vertical direction. The lead screw 22 is threadedly connected to a lifting plate 7. Multiple connecting rods 21 are rotatably connected to the lifting plate 7 along the circumferential direction, and each connecting rod 21 is rotatably connected to the end of a sliding rod 20. A motor 3 27 is fixedly connected to one side of the upper surface of the rectangular frame 38. The output end of the motor 3 27 is fixedly connected to one end of the lead screw 22.

[0049] like Figure 2 As shown, a motor 8 for driving the rotating shaft 11 to rotate is fixedly connected to the top of the conveying cylinder 5, and the output end of the motor 8 is fixedly connected to the top of the rotating shaft 11.

[0050] Specifically, in the existing technology, when treating collected rainwater, the rainwater is first introduced into a purification well, and then solid agents such as flocculants are added to the purification well and stirred. This destabilizes the small, non-precipitating suspended particles in the water and causes them to aggregate into large flocs, accelerating sedimentation and thus removing suspended solids from the rainwater.

[0051] However, as sediment continues to form, it accumulates at the bottom of the well, not only reducing the effective volume within the well and causing the actual treatment capacity of the purification well to continuously decrease with prolonged operation, but also, if the bottom sediment is not cleaned for a long time, anaerobic fermentation can easily occur. The resulting bubbles will rise to the surface, carrying impurities and re-polluting the upper clear water, leading to a deterioration of the effluent quality. Furthermore, when it is necessary to clean the sediment at the bottom of the well, it is usually necessary to shut down the machine and use manual or mechanical cleaning methods. This operation is cumbersome, labor-intensive, and the purification well cannot work normally during the cleaning cycle, seriously affecting the continuity and overall efficiency of rainwater treatment.

[0052] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows:

[0053] In the initial state, the four traction plates 24 are located at the four corners of the purification well body 1, and the bottom of the traction plates 24 and the filter cloth 23 are in contact with the bottom surface of the inner cavity of the purification well body 1, and the filter cloth 23 is in a flat and taut state.

[0054] The collected rainwater is introduced into the hydrocyclone 2 through its inlet. The swirling motion generates centrifugal force, causing heavy, coarse particles such as sand and gravel in the rainwater to move towards the outer wall and settle, while the lighter, clean water is pushed towards the center, forming an upward swirling flow. This flow is then discharged from the overflow outlet into the main body 1 of the purification well. This process is for the initial removal of solid impurities from the rainwater to ensure the efficient operation of subsequent reactions. This process is existing technology and will not be described in detail here.

[0055] When rainwater enters the main body 1 of the purification well, it is contained within a rectangular barrier composed of four filter cloths 23. The required flocculant is added to the main body 1 of the purification well, and then the motor 14 drives the stirring rod 13 on one side to rotate. Under the transmission of the sprocket 15 and the chain 17, multiple stirring rods 13 rotate synchronously. The stirring blades on the stirring rods 13 agitate the rainwater, ensuring that the added flocculant is fully mixed with the rainwater, thereby accelerating the floc formation and sedimentation process.

[0056] During the reaction, as the precipitate continuously accumulates at the bottom of the purification well body 1, the lifting plate 7 is lowered by rotating the lead screw 22 driven by motor 3 27. Simultaneously, multiple connecting rods 21 drive multiple sliding rods 20 to slide laterally, causing multiple traction plates 24 to approach the conveying cylinder 5. At the same time, four motors 4 29 drive four rollers 26 to rotate, winding up the filter cloth 23, thus proportionally reducing the volume of the rectangular barrier. During this reduction, the precipitate gathers towards the center of the purification well body 1 until the four filter cloths 23 are in contact with the four sides of the outer wall of the conveying cylinder 5. Before the filter cloth 23 is in contact with the outer wall of the conveying cylinder 5, the lead screw guide module 18 can be activated, using its slider to raise the support plate 10, causing multiple stirring rods 13 to be removed from the water, preventing the stirring rods 13 from affecting the contact between the filter cloth 23 and the outer wall of the conveying cylinder 5. At this time, since the sediment is gathered at the bottom of the conveying cylinder 5 and is within the conveying range of the auger blade 12, the auger blade 12 can be rotated by the motor 8, so that the sediment rises along the rectangular barrier and the inner cavity of the conveying cylinder 5, and is finally discharged through the discharge pipe 6.

[0057] Subsequently, by resetting the rectangular barrier and repeating the above operation, the sediment at the bottom of the purification well body 1 can be cleaned periodically and automatically. This scheme utilizes a retractable rectangular barrier to gather sediment towards the center and discharge it directly through the auger blades 12, eliminating the need for downtime cleaning and ensuring continuous operation of rainwater treatment. Furthermore, the fact that the sediment gathers before being discharged facilitates collection. In addition, the real-time discharge of sediment prevents it from accumulating at the bottom of the well and occupying effective volume, maintaining the stable treatment capacity of the purification well body 1. Simultaneously, it eliminates the possibility of anaerobic fermentation and re-contamination of the upper clear water by rising air bubbles carrying impurities due to prolonged sediment residue, ensuring stable effluent quality. The entire cleaning process requires no manual entry into the well, significantly reducing labor intensity and maintenance costs.

[0058] Furthermore, each time the rectangular barrier is reset, it can be driven to rise by the screw guide module 219 to move it away from the bottom of the well, and then reset. This can prevent the rectangular barrier from pushing subsequent sediments to the inner wall of the purification well body 1, thus preventing the sediments from being collected normally.

[0059] Example 2:

[0060] like Figure 2 , Figure 7 , Figure 8 As shown, it includes a reset-co-fertilizer addition auxiliary component;

[0061] The reset-coordinated flocculant addition auxiliary component includes four mounting plates 16, which are fixedly connected to the top of four traction plates 24. A spraying cylinder 25 is rotatably connected to the middle of the upper surface of the mounting plate 16. The spraying cylinder 25 has multiple rows of through holes 30 along its circumference. Multiple annular blades 33 are fixedly connected to the inner wall of the spraying cylinder 25 along its vertical direction, and each annular blade 33 is aligned with a ring of through holes 30. A chemical hopper 4 is fixedly connected to the top of the conveying cylinder 5. The bottom of the chemical hopper 4 has a discharge port with a valve on it, and multiple branch pipes 9 are connected to the discharge port along its circumference.

[0062] like Figure 7 As shown, a motor 32 is fixedly connected to the middle of the lower surface of the mounting plate 16, and the output end of the motor 32 is fixedly connected to the bottom of the spraying cylinder 25.

[0063] like Figure 8As shown, a cover 28 is rotatably connected to one side of the top of the spraying cylinder 25. A motor 34 is fixedly connected to one side of the top of the spraying cylinder 25. The output end of the motor 34 is fixedly connected to one end of the cover 28. A gear ring 37 is rotatably fitted on the top of the outer wall of the spraying cylinder 25. Multiple cover plates 31 with the same number of rows as the through holes 30 are fixedly connected to the lower surface of the gear ring 37 along the circumferential direction. The cover plates 31 fit against the outer wall of the spraying cylinder 25. A gear 36 is rotatably connected to one side of the top of the outer wall of the spraying cylinder 25. The gear 36 meshes with the gear ring 37. A motor 35 is fixedly connected to one side of the top of the spraying cylinder 25. The output end of the motor 35 is fixedly connected to the rotating end of the gear 36.

[0064] Specifically, in the above embodiments, although the sedimentation process can be accelerated by stirring, when the flocculant is added to the main body 1 of the purification well manually or with the help of tools, the flocculant is easily unevenly distributed on the water surface due to the single addition point. This requires a longer stirring time to achieve uniform mixing, which not only prolongs the single treatment cycle and reduces the treatment efficiency, but also easily leads to waste when the local concentration of flocculant is too high. Suspended particles in the insufficiently mixed areas cannot be effectively destabilized and flocculated because they do not come into contact with sufficient flocculant, thus affecting the purification effect.

[0065] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows:

[0066] First, the flocculant is added into the agent hopper 4 through the top opening. Before rainwater enters the main body 1 of the purification well, multiple traction plates 24 are moved to the edge of the delivery cylinder 5. At this time, multiple spraying cylinders 25 are aligned with multiple branch pipes 9, and the valves on the discharge ports at the bottom of the agent hopper 4 are opened, allowing the flocculant to flow through the discharge ports to each branch pipe 9 and then into each spraying cylinder 25. Furthermore, the multiple rows of through holes 30 on the spraying cylinders 25 are covered by multiple cover plates 31, preventing the flocculant from flowing out of the through holes 30.

[0067] After an appropriate amount of flocculant is discharged through the agent hopper 4, close the valve at the discharge port. At this time, rainwater can be introduced into the main body 1 of the purification well. Subsequently, drive the four traction plates 24 to reset to the four corners of the main body 1 of the purification well. During the reset process, the motor 6 34 drives the cylinder cover 28 to rotate, sealing the top of the spraying cylinder 25. Simultaneously, motor 5 (32) drives the dosing cylinder 25 to rotate. After the dosing cylinder 25 reaches a certain speed, motor 7 (35) drives gear 36 to rotate, causing gear ring 37 and multiple cover plates 31 to rotate. This removes the cover plates 31 from covering the through holes 30, allowing the flocculant in the dosing cylinder 25 to be thrown out through the through holes 30 under centrifugal force. As the flocculant exits through the through holes 30, it impacts the annular blades 33, which cut the flocculant, resulting in fine particles that are evenly distributed across the entire water surface. This achieves simultaneous dosing at multiple points over a large area, avoiding uneven distribution caused by a single dosing point, shortening the mixing time required for uniform mixing, and improving treatment efficiency. Furthermore, the even dispersion of the flocculant prevents waste caused by excessively high local concentrations and ensures that suspended particles in each area come into contact with sufficient flocculant for effective destabilization and flocculation, further guaranteeing the purification effect.

[0068] Furthermore, each time the rectangular barrier changes volume, the dosing cylinder 25 moves laterally back and forth within the purification well body 1, passing through multiple locations on the water surface, resulting in a wider and more uniform distribution of the flocculant. Simultaneously, each time the rectangular barrier shrinks and gathers sediment towards the conveying cylinder 5, the dosing cylinder 25 precisely moves below the reagent hopper 4, collecting a specific amount of flocculant as needed based on the actual purification requirements. When the rectangular barrier repositions and expands, the dosing cylinder 25 returns and evenly distributes the newly collected flocculant. In this way, the sediment discharge and reagent replenishment actions work in tandem, automatically and as needed replenishing flocculant in each cleaning cycle, achieving continuous and efficient reagent dosing.

[0069] Example 3:

[0070] like Figure 1 As shown, it includes deodorizing components;

[0071] The deodorization component includes a filter box 3 connected to one side of the bottom of the purification well body 1, a drain outlet on one side of the filter box 3, and an activated carbon adsorption plate 39 on the inner wall of the filter box 3.

[0072] Specifically, the purified rainwater enters the inner cavity of the filter box 3 from the bottom of the purification well body 1, flows through the activated carbon adsorption plate 39 for deodorization treatment, removes residual odors in the water, further improves the quality of the effluent, and makes it more suitable for reuse or discharge in compliance with standards.
