Description

Technical Field

[0001] This invention relates to water treatment equipment technology, specifically to an integrated device for synergistic disinfection using ultraviolet light and ultrasound. Background Technology

[0002] Ultraviolet (UV) disinfection technology is widely used in water treatment due to its broad-spectrum sterilization and lack of chemical additives. However, due to the inherent characteristics of UV light's short penetration distance and easy attenuation in water, traditional UV disinfection devices generally suffer from uneven water flow irradiation: dead zones or short-circuiting easily occur within the disinfection chamber, and some parts of the water to be treated receive UV doses far below the design value, making it difficult to consistently achieve the desired overall disinfection effect.

[0003] To improve hydraulic conditions and enhance water mixing, methods such as adding mechanical agitators or configuring recirculation pipelines are commonly used. However, mechanical agitators not only increase energy consumption and structural complexity but also have a limited mixing range, making it difficult to force all the water in the entire cavity to continuously tumble around the ultraviolet light source. Meanwhile, simple pipeline recirculation can only generate local turbulence, which has very limited effect on eliminating macroscopic flow dead zones and achieving uniform mixing throughout the entire field.

[0004] When existing equipment is in operation, on the one hand, the penetration distance of ultraviolet light in water is limited. If the water body is in a static or laminar flow state, dead zones can easily form inside the disinfection chamber, resulting in insufficient ultraviolet light dose received by some water bodies, ultimately leading to unstable overall disinfection effects. On the other hand, when treating wastewater containing suspended solids, hardness ions, or microorganisms, the return port of the return pipe is immersed in water for a long time, and biofilm and scale easily adhere to the inner wall of the pipe, while also trapping suspended impurities, causing the port diameter to narrow or even become blocked. Once the return flow is obstructed, the aforementioned function of improving water mixing will also be lost, ultimately leading to a sharp deterioration in disinfection effects. Therefore, an integrated device for synergistic disinfection of ultraviolet light and ultrasound has been developed. Summary of the Invention

[0010] The cleaning plate is rotatably disposed around the end of the cover plate, and the ends of the cleaning plates are rotatably connected to each other, so that the cleaning plate rotates along the end of the cover plate and fits against the inner wall of the outlet end of the circulation pipe to clean the impurities clogging the return end.

[0011] The ultrasonic transducer's ultrasonic action area at least covers the return end of the circulation pipe, so as to utilize the cavitation effect to assist the protective component in removing impurities from the inner wall.

[0012] As a further optimization of the present invention, the adjustment component further includes a fixing plate that is snapped into the support plate, and a fixing block is snapped into the inner wall of the fixing plate;

[0013] The fixed plate has multiple sets of arc-shaped plates evenly arranged at its ends, and the ends of the arc-shaped plates are provided with arc-shaped grooves.

[0014] As a further optimization of the present invention, a locking plate is snapped onto the end of the fixing block, and the outer surface of the locking plate is rotatably connected to the end of the locking block;

[0015] The locking block has a locking groove at its end, and an elastic element is fixedly installed on the inner wall of the locking groove.

The outer surface of the positioning block is engaged with a positioning plate, and the outer surface of the positioning plate is uniformly provided with multiple sets of positioning grooves.

[0018] As a further optimization of the present invention, a protective block is slidably fitted into the inner wall of the positioning groove, and the end of the protective block is engaged with the end of the protective plate.

[0019] As a further optimization of the present invention, a rotating plate is rotatably provided on the outer surface of the positioning block, and a rotating groove corresponding to the protective block is opened at the end of the rotating plate, and the inner wall of the rotating groove is slidably connected to the outer surface of the end of the protective block.

[0020] As a further optimization of the present invention, a telescopic member is fixedly provided at the end of the positioning block, the end of the telescopic member is engaged with the end of the cover plate, and a limiting ring is engaged on the outer surface of the telescopic member.

[0023] Compared with the prior art, the integrated ultraviolet and ultrasonic disinfection device provided by the present invention has the following beneficial effects:

[0024] By dynamically regulating the flow pattern of the circulating liquid through the adjustment components, different blade shapes can be switched according to the actual operating state of the disinfection chamber. This creates a stable, upward-flowing annular turbulent flow within the disinfection chamber, causing the water in the entire chamber to continuously tumble and mix around the ultraviolet light source. This completely eliminates static flow dead zones, ensuring that every part of the water to be disinfected receives sufficient and uniform ultraviolet irradiation. This fundamentally solves the problems of uneven water irradiation and insufficient ultraviolet dose in some parts of the water.

[0025] The protective components continuously clean the inner wall of the circulating pipe outlet. Combined with the cavitation effect generated by the ultrasonic transducer, the impurities attached to the inner wall are peeled off, preventing biofilm, scale, and trapped suspended impurities from clogging the return port. This ensures that the return pipeline is always unobstructed, allowing the annular turbulent flow to be formed and maintained stably, thus ensuring the long-term stability of the device's disinfection effect.

[0026] With the coordinated action of the adjustment and protection components, the direction of water flow can be switched when the blade unfolding angle is adjusted, which simultaneously drives the protection plate to move outward, thereby pushing the cleaning plate to open along the outer periphery of the cover plate and fit against the inner wall of the circulation pipe. This allows the flow pattern adjustment and the inner wall cleaning operation to be matched synchronously, which simplifies the overall structure of the device and ensures that the cleaning action can be adaptively adjusted with the change of the return flow rate, thereby improving the overall coordinated operation efficiency of the device.

[0038] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0039] Example: Please refer to Figure 1 - Figure 8 An integrated device for synergistic disinfection of ultraviolet light and ultrasound includes a disinfection body 1, a circulation tube 11 connected to the disinfection chamber is snapped into the inner cavity of the disinfection body 1, and a support plate 12 is fixedly installed on the inner wall of the circulation tube 11.

[0040] In this scheme, the circulation pipe 11 consists of two sections of pipe, one for inlet and one for outlet. The return end extends to the bottom area of ​​the disinfection chamber, guiding the upper water flow of the disinfection chamber to the bottom for recirculation. Together with the ultraviolet disinfection lamp and the ultrasonic transducer installed on the outside of the return end, they work together to complete the synergistic disinfection operation.

[0041] The support plate 12 consists of an annular support plate and a radial support rod. An installation space is reserved at its center to support the assembly adjustment component 2 and the protective component 3. This will not cause excessive obstruction to the liquid flow inside the circulation pipe 11, and will provide stable structural support for each functional component.

[0042] Furthermore, the adjustment component 2, which is assembled at the end of the support plate 12, includes a locking block 231, a connecting block 26, and a blade 27 for regulating the flow pattern of the circulating liquid; the end of the connecting block 26 is engaged with the end of the blade 27, and the end of the connecting block 26 is fixedly connected to the end of the locking block 231, so that the connecting block 26 rotates synchronously with the locking block 231, and switches the blade 27 to different forms to form an annular turbulent flow flowing from bottom to top in the disinfection chamber.

[0043] In this embodiment, by driving the connecting block 26 to rotate synchronously through the locking block 231, the overall unfolding angle and orientation of the blade 27 can be changed, so that the blade 27 can be arranged in a conical shape with different tilt angles, thereby regulating the liquid flow rate and flow direction in the circulation pipe 11.

[0044] When the blade 27 expands at an angle, the flow area of ​​the circulation pipe 11 decreases and the liquid flow rate increases. This allows for a stronger turbulent water flow to be ejected from the bottom of the disinfection chamber, forcing the water in the chamber to rotate as a whole, ensuring that every part of the water can receive sufficient ultraviolet radiation.

[0045] When the blade 27 unfolds at a smaller angle, the circulation resistance decreases, making it suitable for low-flow processing conditions and avoiding extra energy waste.

[0046] Furthermore, the adjustment assembly 2 also includes a fixing plate 21 that is snapped into the support plate 12, and a fixing block 211 is snapped into the inner wall of the fixing plate 21; multiple sets of arc plates 22 are evenly arranged at the end of the fixing plate 21, and arc grooves 221 are opened at the end of the arc plates 22.

[0047] Specifically, the fixing block 211 is fixed by snapping into the reserved area at the center of the support plate 12. Multiple sets of arc plates 22 are evenly arranged around the axis of the fixing plate 21. The arc groove 221 is opened along the arc of the arc plate 22. The docking block 241 is used to switch the angle of the blade 27 and lock the adjusted angle. No additional locking structure is needed to maintain the blade 27 at the current working angle.

[0048] The end of the fixed plate 21 is equipped with a power output device such as a motor, and is connected to an external control device to drive the fixed plate 21 to rotate as a whole.

[0049] Furthermore, a locking plate 23 is snapped onto the end of the fixing block 211, and the outer surface of the locking plate 23 is rotatably connected to the end of the locking block 231; a locking groove 232 is provided at the end of the locking block 231, and an elastic element 25 is fixedly provided on the inner wall of the locking groove 232.

[0050] Specifically, the inner cavity of the fixed block 211 is equipped with a device with power output such as a motor, and is connected to an external control device to drive the locking plate 23 to rotate. The locking plate 23 is generally ring-shaped, providing rotational support for the locking block 231. The elastic element 25 is specifically a compression spring, which normally pushes the moving block 24 to extend outward to the locking groove 232, providing an outward pushing force for the mating block 241, so that the mating block 241 remains in the fitting state with the arc-shaped groove 221.

[0051] Furthermore, a movable block 24 is slidably provided on the inner wall of the locking groove 232. The side of the movable block 24 is connected to the end of the elastic member 25. At the same time, a docking block 241 is snapped onto the end of the movable block 24. The outer surface of the docking block 241 is fitted and slidably connected to the inner wall of the arc groove 221.

[0052] Specifically, the movable block 24 slides radially inside the locking groove 232. When the angle of the blade 27 needs to be adjusted, the locking block 231 drives the movable block 24 and the docking block 241 to rotate together. The docking block 241 moves along the inner wall of the arc groove 221. The inner wall of the arc groove 221 has a positioning slot for different blade 27 angles. When the docking block 241 rotates to the target positioning slot, the elastic element 25 pushes the movable block 24 outward to insert the docking block 241 into the positioning slot, thus completing the locking of the blade 27 angle. The operation is convenient and the positioning is stable.

[0053] By switching the blades 27, the liquid flow state at the outlet of the circulation pipe 11 can be changed, forming a stable annular turbulent flow inside the disinfection chamber. This drives the water in the entire chamber to continuously tumble and mix, completely eliminating dead zones or short-circuit problems. This ensures that all the water to be disinfected can fully come into contact with ultraviolet light, guaranteeing sufficient disinfection dosage and ensuring that the overall disinfection effect is stable and meets the standards. At the same time, the angle of the blades 27 can be flexibly adjusted according to the actual treatment flow rate and disinfection requirements, taking into account both the mixing effect and operating energy consumption, and adapting to different treatment conditions.

[0054] At the moment when the ultrasonic cavitation intensity is the highest and the displacement is the largest (when the ultraviolet pulse is off), the blade 27 briefly reverses, generating a downward flushing water flow that impacts the attached impurities. The energy from the collapse of the cavitation bubbles helps to loosen the bottom deposits, while avoiding interference with ultraviolet radiation and ensuring a stable and continuous ultraviolet irradiation disinfection process.

[0055] The ultrasonic cavitation effect removes biofilm and scale adhering to the inner wall of the pipe, further enhancing the cleaning effect. After rinsing, the blade 27 can be reset and returned to the normal working angle, which will not affect the normal disinfection operation of the device. At the same time, it can also prevent the scraped impurities from redepositing in local areas, achieving continuous self-cleaning of "scraping-rinsing-draining".

[0056] Furthermore, the protective component 3, which is assembled at the end of the regulating component 2, includes a protective plate 331, a cover plate 351, and a cleaning plate 37 for cleaning the inner wall of the return end. The cleaning plate 37 is rotatably disposed around the end of the cover plate 351, and the ends of the cleaning plates 37 are rotatably connected to each other, so that the cleaning plate 37 rotates along the end of the cover plate 351 and fits against the inner wall of the outlet end of the circulation pipe 11 to clean impurities clogging the return end. The ultrasonic action area of ​​the ultrasonic transducer at least covers the return end of the circulation pipe 11 to utilize the cavitation effect to assist the protective component 3 in removing impurities from the inner wall.

[0057] In this embodiment, after the cleaning plate 37 rotates and opens around the cover plate 351, its outer edge can closely fit the inner wall of the return end of the circulation pipe 11. When the telescopic member 35 pushes the cover plate 351 to move axially, the cleaning plate 37 moves axially synchronously with the cover plate 351, so that the cleaning plate 37 changes from a contracted state to an expanded state. It can scrape and clean the scale, biofilm and trapped suspended impurities attached to the inner wall of the circulation pipe 11, avoid the return port from narrowing and blockage, ensure that the return pipeline is always unobstructed, and complete the cleaning operation without disassembling the device, which greatly reduces the difficulty and cost of maintenance.

[0058] The ultrasonic transducer's ultrasonic action area covers at least the return end of the circulation pipe 11. It utilizes the cavitation effect of ultrasound to generate a large number of microbubbles in the water. The local shock waves generated when the microbubbles collapse can loosen the bond between impurities and the pipe wall, making it easier for the auxiliary protection component 3 to peel off the impurities attached to the inner wall, further improving the cleaning effect and reducing the power consumption of the cleaning process.

[0059] Furthermore, the protective component 3 also includes a positioning block 31 that is snapped into the fixing plate 21. A positioning plate 32 is snapped into the outer surface of the positioning block 31. Multiple sets of positioning grooves 321 are evenly opened on the outer surface of the positioning plate 32.

[0060] Specifically, after the positioning block 31 is fixedly connected to the fixing plate 21, the whole block rotates synchronously with the fixing plate 21, while providing a stable installation base for the positioning plate 32. Multiple positioning grooves 321 are evenly arranged around the positioning plate 32 to provide limiting guidance for the sliding of the protective block 33, so that the protective block 33 can move stably along the preset trajectory, ensuring the consistency of the opening and closing process of the cleaning plate 37.

[0061] An elastic telescopic component is provided between the positioning block 31 and the fixing plate 21, so that the cover plate 351 is rotatably connected to the end of the circulation pipe 11, and the cleaning plate 37 rotatably set at its end is still attached to the inner wall of the end of the circulation pipe 11 after adjustment.

[0062] Furthermore, a protective block 33 is slidably fitted into the inner wall of the positioning groove 321, and the end of the protective block 33 is engaged with the end of the protective plate 331.

[0063] Specifically, the protective block 33 slides radially along the positioning groove 321, which can drive the protective plate 331 to move radially synchronously. The radial movement of the protective plate 331 provides transmission support for the opening and closing movement of the cleaning plate 37. With the help of the limiting rod 361, multiple cleaning plates 37 can be driven to complete the action synchronously, ensuring that the position and movement of each cleaning plate 37 are consistent.

[0064] Furthermore, a rotating plate 34 is rotatably provided on the outer surface of the positioning block 31, and a rotating groove 341 corresponding to the protective block 33 is opened at the end of the rotating plate 34. The inner wall of the rotating groove 341 is slidably connected to the outer surface of the end of the protective block 33.

[0065] Specifically, when the rotating plate 34 rotates around the axis of the positioning block 31, the rotating groove 341 will push the protective block 33 to move radially along the positioning groove 321 through the groove wall. The inner cavity of the positioning block 31 is provided with a torsion spring to limit the rotating plate 34.

[0066] When the rotating plate 34 rotates clockwise, the rotating groove 341 pushes the protective block 33 to move outward, thereby driving the protective plate 331 to move outward synchronously, providing power for the unfolding action of the cleaning plate 37. When rotating in the opposite direction, it can drive the protective block 33 and the protective plate 331 to retract, so that the cleaning plate 37 can complete the retraction. The overall transmission process is smooth and stable, and the power transmission efficiency is high.

[0067] Furthermore, a telescopic member 35 is fixedly provided at the end of the positioning block 31, the end of the telescopic member 35 is engaged with the end of the cover plate 351, and a limiting ring 36 is engaged on the outer surface of the telescopic member 35.

[0068] Specifically, the telescopic component 35 is a component with telescopic function such as an electric telescopic rod, which can drive the cover plate 351 to move linearly along the axial direction of the circulation pipe 11. The limiting ring 36 is fixed on the outside of the rod body of the telescopic component 35, providing a mounting fulcrum for the limiting rod 361 and ensuring that the limiting rod 361 can move synchronously with the telescopic component 35.

[0069] Furthermore, a limiting rod 361 is uniformly rotatably provided on the outer surface of the limiting ring 36, and the end of the limiting rod 361 away from the limiting ring 36 is rotatably connected to the outer surface of the cleaning plate 37.

[0070] Specifically, the two ends of the limiting rod 361 are hinged to the limiting ring 36 and the cleaning plate 37, respectively. When the protective plate 331 drives the end of the cleaning plate 37 to move radially, the limiting rod 361 will deflect accordingly, causing the other end of the cleaning plate 37 to open outward, automatically completing the unfolding action. The same applies when retracting. The action response is rapid, the structure is highly reliable, and there will be no jamming or sticking problems.

[0071] Furthermore, a cleaning groove 371 is provided on the outer surface of the cleaning plate 37, and the inner wall of the cleaning groove 371 is slidably connected to the outer surface of the end of the protective plate 331.

[0072] Specifically, the cleaning groove 371 provides a space for the protective plate 331 to move. The end of the protective plate 331 can slide in the cleaning groove 371 to adapt to the relative displacement of the cleaning plate 37 during the opening and closing process, avoid motion interference between components, and ensure that the entire cleaning action can be completed smoothly.

[0073] When the cleaning plate 37 is extended to its maximum position, it will fit tightly against the isolation net at the end of the circulation pipe 11 to remove impurities remaining on the isolation net, prevent the isolation net from becoming blocked, and ensure that the water flow can continuously and stably enter the circulation pipe 11 through the return end, maintaining the normal circulation disturbance of the water in the disinfection chamber.

[0074] Working principle: During operation, the unfolding angle of the blade 27 is pre-adjusted according to the flow rate and treatment requirements of the water to be treated, driving the locking plate 23 to rotate the locking block 231. The locking block 231 drives the moving block 24 and the docking block 241 to rotate synchronously. After the docking block 241 moves along the arc groove 221 to the positioning slot corresponding to the preset angle, the elastic element 25 pushes the moving block 24 to pop outward, and the docking block 241 is inserted into the positioning slot to complete the angle locking.

[0075] At this point, after the water to be disinfected enters the disinfection chamber, it flows back to the bottom of the disinfection chamber through the circulation pipe 11. After the angle is adjusted by the blades 27, the water is guided and sprayed out from the bottom of the disinfection chamber in a directional turbulent flow. This causes the water in the entire disinfection chamber to complete a circular overturning flow, eliminating dead zones and ensuring that all water can fully receive the synergistic disinfection of ultraviolet light and ultrasound, thus ensuring a uniform and stable disinfection effect.

[0076] When it is necessary to clean the attached impurities on the inner wall of the return end of the circulation pipe 11, the rotating plate 34 is first driven to rotate. The rotating plate 34 pushes the protective block 33 to move outward along the positioning groove 321 through the rotating groove 341. The protective block 33 drives the protective plate 331 to move outward synchronously. The protective plate 331 pushes one end of the cleaning plate 37 to move outward through the cleaning groove 371. With the hinge transmission of the limiting rod 361, the entire cleaning plate 37 opens outward, so that the outer edge of the cleaning plate 37 fits against the inner wall of the return end of the circulation pipe 11.

[0077] The ultrasonic transducer is then activated to emit ultrasonic waves into the return end region, which loosen the impurities attached to the pipe wall through cavitation.

[0078] Then, the telescopic component 35 is activated, which drives the limiting ring 36 to move. The limiting ring 36 drives the already opened cleaning plate 37 to move axially through the limiting rod 361, scraping away the scale, biofilm and intercepted impurities attached to the inner wall of the return end of the cleaning circulation pipe 11 and the surface of the end isolation net.

[0079] After cleaning, the telescopic component 35 drives the cover plate 351 to reset, the rotating plate 34 rotates in the opposite direction, driving the protective block 33 and the protective plate 331 to retract inward, so that the cleaning plate 37 retracts and resets, ready for the next cleaning operation.

[0080] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
