Description

Technical Field

[0001] The embodiments of the present invention relate to the field of domestic water disinfection technology, specifically, to a domestic water ozone disinfection device. Background Technology

[0002] Ozone disinfection devices for domestic water are equipment that uses ozone as a disinfectant. They are widely used in the disinfection of drinking water and domestic water in homes, hotels, restaurants, medical facilities, and other places. Ozone is a strong oxidant that can effectively kill bacteria, viruses, and other pathogenic microorganisms in water, while also removing odors and harmful substances.

[0003] Patent publication number CN211896224U relates to an ozone disinfection device for domestic water, comprising a disinfection tank, a main ozone aeration system, an auxiliary ozone aeration system, and an ozone tail gas treatment system. The main ozone aeration system consists of an ozone blower from an ozone preparation device and a main ozone aeration disc connected by pipes. The auxiliary ozone aeration system consists of an ozone tail gas collection pipeline, a water seal tank, an auxiliary ozone delivery pipeline, an auxiliary ozone blower, and an auxiliary ozone aeration disc connected sequentially. The ozone tail gas treatment system collects a portion of the tail gas from the disinfection tank, which is then treated by a heated ozone tail gas decomposer via an ozone tail gas discharge pipeline before being safely and pollution-free discharged. This ozone-water mixed disinfection equipment can significantly improve ozone utilization, ensure disinfection effectiveness, reduce ozone production, and save energy. It also features stable effluent, high safety, and high environmental performance.

[0004] In the aforementioned patent, the system is composed of interconnected pipes. The auxiliary ozone aeration system consists of an ozone tail gas collection pipe, a water seal tank, an auxiliary ozone delivery pipe, an auxiliary ozone blower, and an auxiliary ozone aeration disc connected in sequence. This improves ozone utilization, ensures disinfection effect, reduces ozone production, and saves energy. However, the way ozone contacts the water is relatively simple, which may result in poor contact and thus affect the disinfection effect of ozone on the water. Therefore, a domestic water ozone disinfection device with better disinfection effect is designed. Summary of the Invention

[0005] To overcome the above-mentioned defects, embodiments of the present invention provide an ozone disinfection device for domestic water, which solves the technical problem that the existing technology has a relatively simple way of contacting ozone with water, which may result in poor contact and thus affect the disinfection effect of ozone on water.

[0006] According to one aspect, at least one embodiment of the present invention provides a domestic water ozone disinfection device, including a tank, an ozone generator fixedly installed on the top of the tank, and an air pump fixedly passing through the top of the ozone generator; The surface of the tank is equipped with a disinfection device for disinfecting water using ozone. The disinfection device includes an ozone delivery shaft that rotatably passes through the surface of the tank. An outlet pipe, an inlet pipe, and a reagent pipe are fixedly connected to the surface of the tank. A guide plate is fixedly installed on the circumferential surface of the ozone delivery shaft. An aeration ring is fixedly connected to the circumferential surface of the ozone delivery shaft. A fixing ring is fixedly installed on the circumferential surface of the ozone delivery shaft. A rotating rod rotatably passes through the surface of the fixing ring. An antifoaming ring is fixedly installed on the circumferential surface of the rotating rod. A filter plate is slidably installed on the inner wall of the tank. The water and flocculant react to react with and clump impurities in the water, preventing localized accumulation or uneven dispersion of the flocculant.

[0007] According to the above technical solution, the ozone generator is sleeved with the ozone delivery shaft, the angle of the guide plate is set to an inclined angle, and one end of the ozone delivery shaft is connected to the motor output end to ensure that suspended impurities and colloids in the water react fully with the flocculant and agglomerate, reducing the leakage of impurities and laying a good foundation for subsequent filtration and disinfection.

[0008] According to the above technical solution, there are two guide plates, which are symmetrically distributed vertically. The water stirring direction of the two guide plates is opposite. The circumferential surface of the ozone conveying shaft is provided with a reciprocating threaded groove. The rotation of the guide plates, in conjunction with the aeration ring, improves the ozone disinfection treatment of the water. The rotation of the aeration ring can expand the diffusion range of ozone in the water and increase the contact area between ozone and water.

[0009] According to another aspect, at least one embodiment of the present invention also provides an ozone disinfection device for domestic water. A pretreatment device for pretreating the water is provided on the circumferential surface of an ozone delivery shaft. The pretreatment device includes a mixing ring slidably mounted on the circumferential surface of the ozone delivery shaft. A limiting plate is slidably mounted on the circumferential surface of the ozone delivery shaft. A telescopic connecting rod is fixedly mounted at the bottom of the limiting plate. A toothed block is fixedly mounted at the bottom of a filter plate. A toothed ring is fixedly mounted on the circumferential surface of the ozone delivery shaft. A cleaning plate is fixedly mounted on the circumferential surface of the toothed ring. A cleaning roller is rotatably mounted on the surface of the cleaning plate. A contact wheel is fixedly mounted on the circumferential surface of the cleaning roller. The defoaming ring revolves to perform preliminary defoaming treatment on the water bubbles inside the tank, thereby increasing the contact area between ozone and water, preventing a large number of bubbles from floating on the water surface and hindering ozone dissolution, allowing ozone to fully integrate into the water, reducing waste from unreacted ozone dissipation, and thus improving disinfection efficiency.

[0010] According to the above technical solution, one end of the telescopic connecting rod away from the limiting plate is rotatably connected to the mixing ring, and the ozone gas delivery shaft is connected to the mixing ring by a thread, so as to fully stir the flocculant and water inside the tank, avoid local water stagnation leading to impurity deposition or uneven ozone concentration, ensure stable operation of the device from water intake, flocculation and disinfection, and reduce failures caused by local abnormalities.

[0011] According to the above technical solution, the circumferential surface of the cleaning roller is provided with bristles for cleaning the filter plate. The toothed block can mesh with the toothed ring after contact. The rotation of the cleaning roller drives the bristles to rotate and clean the bottom of the filter plate to avoid the accumulation of impurities on the surface of the filter plate, which would block the filter holes and affect the filtration effect and efficiency.

[0012] According to another aspect, at least one embodiment of the present invention also provides a domestic water ozone disinfection device. The circumferential surface of the ozone delivery shaft is provided with a defoaming device for eliminating air bubbles inside the tank. The defoaming device includes a sleeve ring fitted onto the circumferential surface of the ozone delivery shaft. A scraper is fixedly installed on the surface of the sleeve ring. A telescopic connecting rod is fixedly installed on the top of the sleeve ring. A contact wheel is rotatably passed through the surface of a fixed ring. A cam is fixedly installed on the circumferential surface of the contact wheel. A contact tooth plate is slidably installed on the surface of the fixed ring. A gear is fixedly installed on the circumferential surface of the rotating rod. A telescopic spring is fixedly installed on the surface of the fixed ring. This device reduces the time and cost of manual maintenance, ensuring continuous operation of the device, by preventing filter blockage that could lead to a decrease in water flow, a sharp drop in filtration efficiency, or even device shutdown.

[0013] According to the above technical solution, the scraper is rotatably connected to the top of the filter plate, and the end of the telescopic connecting rod away from the sleeve ring is fixedly connected to the ozone gas delivery shaft. The rotation of the scraper cleans the top of the filter plate, which further improves the cleaning effect and efficiency of the filter plate, further reduces the probability of filter hole blockage, extends the service life of the filter plate, and reduces the replacement frequency of filter components.

[0014] According to the above technical solution, the second contact wheel contacts the inner wall of the tank, the contact tooth plate meshes with the gear, and the defoaming ring rotates to further defoam the bubbles generated when the water inside the tank comes into contact with ozone. Compared with the initial defoaming, the secondary defoaming of the bubbles generated when ozone comes into contact with water is more effective in breaking up tiny bubbles.

[0015] According to the above technical solution, the end of the contact tooth plate near the cam is provided with an arc surface for assisting the cam in bearing force, and the free end of the telescopic spring rod is fixedly connected to the end of the contact tooth plate away from the cam, so that ozone is fully released from the bubbles and dissolved into the water, further reducing ozone dissipation.

[0016] The beneficial effects of the embodiments of the present invention are as follows: In this invention, ozone is injected into the ozone delivery shaft through an ozone generator, while water is pumped into the tank through the inlet pipe. Subsequently, flocculant is injected into the tank through the reagent pipe. At this time, the water and flocculant react, reacting and agglomerating the impurities in the water. This avoids local accumulation or uneven dispersion of the flocculant, ensuring that suspended impurities and colloids in the water fully react with the flocculant and agglomerate, reducing the amount of impurities missed, and laying a good foundation for subsequent filtration and disinfection.

[0017] In this invention, the aeration ring rotates, driving the aeration holes to rotate and thus aerate the inside of the tank for ozone aeration. Simultaneously, the rotation of the guide plate, in conjunction with the aeration ring, enhances the ozone's disinfection effect on the water. The rotational aeration expands the ozone's diffusion range in the water, increasing the contact area between ozone and the water. The rotation of the ozone delivery shaft drives the fixed ring to rotate, which in turn drives the rotating rod. Simultaneously, the rotating rod drives the defoaming ring to rotate. The defoaming ring's revolution around the tank initially defoams the water bubbles inside, thereby increasing the contact area between ozone and the water. This prevents a large number of bubbles from floating on the surface and hindering ozone dissolution, allowing the ozone to fully integrate into the water and reducing waste from unreacted ozone dissipation, ultimately improving disinfection efficiency.

[0018] In this invention, the mixing ring and the ozone delivery shaft are connected by a thread. When the ozone delivery shaft rotates, it drives the mixing ring to rotate. The rotation of the mixing ring fully stirs the flocculant and water inside the tank, avoiding local water stagnation that could lead to impurity deposition or uneven ozone concentration. This ensures stable operation of the device throughout the entire process of water intake, flocculation, and disinfection, and reduces malfunctions caused by local anomalies.

[0019] In this invention, the contact wheel rotates around the filter plate and rotates on its own axis under the contact action at the bottom. At this time, the rotation of the contact wheel drives the cleaning roller to rotate, which in turn drives the bristles to rotate and clean the bottom of the filter plate, preventing the filter holes from being blocked by the accumulation of impurities on the filter plate surface. This would affect the filtration effect and efficiency, reduce the water flow rate caused by the blockage of the filter holes, cause a sharp drop in filtration efficiency, and even shut down the device. This invention reduces the time and cost of manual maintenance and ensures continuous operation of the device. The telescopic connecting rod moves to release the restriction on the chemical tube and at the same time briefly increases the instantaneous flow rate of the inlet pipe to offset the flocculant added into the tank to achieve a balance and avoid water concentration imbalance caused by the addition of flocculant.

[0020] In this invention, the rotation of the mixing ring drives the rotation of the telescopic connecting rod, which in turn drives the rotation of the sleeve ring. The rotation of the sleeve ring drives the scraper to clean the top of the filter plate, further improving the cleaning effect and efficiency of the filter plate, reducing the probability of filter hole clogging, extending the service life of the filter plate, and reducing the replacement frequency of filter components. The movement of the contact toothed plate drives the gear to rotate, and the rotation of the gear drives the rotating rod to rotate. The rotation of the rotating rod drives the defoaming ring to rotate. At this time, the rotation of the defoaming ring further defoams the bubbles generated when the water inside the tank comes into contact with ozone. Compared with the initial defoaming, the secondary defoaming of the bubbles generated when ozone comes into contact with water is more effective in breaking up tiny bubbles, allowing ozone to be fully released from the bubbles and dissolved into the water, further reducing ozone escape.

[0030] like Figures 1-7 As shown, it illustrates an ozone disinfection device for domestic water according to an embodiment of the present invention, including a tank 1, an ozone generator 2 fixedly installed on the top of the tank 1, and an air pump 3 fixedly passing through the top of the ozone generator 2. The surface of the tank 1 is equipped with a disinfection device for disinfecting water with ozone. The disinfection device includes an ozone conveying shaft 41, which rotatably passes through the surface of the tank 1. An outlet pipe 42 is fixedly passed through the surface of the tank 1, an inlet pipe 43 is fixedly passed through the surface of the tank 1, and a chemical tube 44 is fixedly passed through the surface of the tank 1. A guide plate 45 is fixedly installed on the circumferential surface of the ozone conveying shaft 41. An aeration ring 46 is fixedly passed through the circumferential surface of the ozone conveying shaft 41. A fixing ring 47 is fixedly installed on the circumferential surface of the ozone conveying shaft 41. A rotating rod 48 rotatably passes through the surface of the fixing ring 47. An antifoaming ring 49 is fixedly installed on the circumferential surface of the rotating rod 48. A filter plate 410 is slidably installed on the inner wall of the tank 1. The filter plate 410 moves downward under the action of the water, causing the toothed block 54 to move.

[0031] The ozone generator 2 is sleeved with the ozone delivery shaft 41. The angle of the guide plate 45 is set to an inclined angle. One end of the ozone delivery shaft 41 is connected to the motor output end. The rotation of the ozone delivery shaft 41 drives the mixing ring 51 to rotate.

[0032] There are two guide plates 45, which are symmetrically distributed vertically. The water stirring direction of the two guide plates 45 is opposite. The circumferential surface of the ozone conveying shaft 41 is provided with a reciprocating threaded groove. The rotation of the guide plates 45 guides and stirs the water inside the tank 1.

[0033] In this example, ozone generator 2 and air pump 3 are started. Through the cooperation of ozone generator 2 and air pump 3, ozone is injected into the ozone delivery shaft 41 through ozone generator 2. At the same time, water is pumped into the tank 1 through water inlet pipe 43. Then, flocculant is added into the tank 1 through chemical pipe 44. At this time, the water and flocculant react, reacting and agglomerating the impurities in the water, avoiding local accumulation or uneven dispersion of flocculant, ensuring that suspended impurities and colloids in the water fully react with the flocculant and agglomerate, reducing the leakage of impurities, and laying a good foundation for subsequent filtration and disinfection. After the reaction, the water enters the lower half of the tank 1 through filter plate 410. At the same time, ozone delivery shaft 41 rotates under the action of motor output. The rotation of ozone delivery shaft 41 drives the guide plate 45 to rotate, and the rotation of guide plate 45 moves the interior of tank 1. The water is guided and stirred. At this time, the ozone delivery shaft 41 rotates, driving the aeration ring 46 to rotate. The rotation of the aeration ring 46 drives the aeration holes to rotate, performing ozone aeration treatment inside the tank 1. At this time, the guide plate 45 rotates in conjunction with the aeration ring 46 to improve the ozone disinfection treatment of the water. The rotation of the aeration can expand the diffusion range of ozone in the water and increase the contact area between ozone and water. At the same time, the rotation of the ozone delivery shaft 41 drives the fixed ring 47 to rotate, which drives the rotating rod 48 to rotate. Simultaneously, the rotation of the rotating rod 48 drives the defoaming ring 49 to rotate. At this time, the defoaming ring 49 revolves to perform preliminary defoaming treatment on the water bubbles inside the tank 1, thereby increasing the contact area between ozone and water, avoiding a large number of bubbles floating on the water surface and hindering ozone dissolution, allowing ozone to be more fully integrated into the water, reducing the waste of ozone that escapes before reacting, and thus improving disinfection efficiency.

[0034] like Figures 1-7 As shown, in another embodiment of the present invention, a pretreatment device for pretreating water is provided on the circumferential surface of the ozone conveying shaft 41. The pretreatment device includes a mixing ring 51, which is slidably mounted on the circumferential surface of the ozone conveying shaft 41. A limiting plate 52 is slidably mounted on the circumferential surface of the ozone conveying shaft 41. A telescopic connecting rod 53 is fixedly mounted on the bottom of the limiting plate 52. A toothed block 54 is fixedly mounted on the bottom of the filter plate 410. A toothed ring 55 is fixedly mounted on the circumferential surface of the ozone conveying shaft 41. A cleaning plate 56 is fixedly mounted on the circumferential surface of the toothed ring 55. A cleaning roller 57 is rotatably mounted on the surface of the cleaning plate 56. A contact wheel 58 is fixedly mounted on the circumferential surface of the cleaning roller 57. The contact wheel 58 rotates under the contact action of the bottom of the filter plate 410.

[0035] The end of the telescopic connecting rod 53 away from the limiting plate 52 is rotatably connected to the mixing ring 51. The ozone gas delivery shaft 41 is connected to the mixing ring 51 by a thread. The rotation of the mixing ring 51 fully stirs the flocculant and water inside the tank 1.

[0036] The circumferential surface of the cleaning roller 57 is provided with bristles for cleaning the filter plate 410. The toothed block 54 can mesh with the toothed ring 55 after contact. The rotation of the toothed block 54 drives the toothed ring 55 to adhere and rotate.

[0037] In this example, when the ozone delivery shaft 41 rotates under the action of the motor output, the mixing ring 51 is connected to the ozone delivery shaft 41 by a thread. The rotation of the ozone delivery shaft 41 drives the mixing ring 51 to rotate. This rotation of the mixing ring 51 thoroughly mixes the flocculant and water inside the tank 1, preventing local water stagnation that could lead to impurity deposition or uneven ozone concentration. This ensures stable operation of the entire process from water intake, flocculation, and disinfection, reducing malfunctions caused by local anomalies. When the filter plate 410 becomes clogged by impurities, it moves downwards under the action of the water, causing the toothed block 54 to move. The toothed block 54 then moves until it engages with the toothed ring 55. The toothed block 54 then rotates, causing the toothed ring 55 to come into contact and rotate. The rotation of the toothed ring 55 drives the cleaning plate 56 to rotate, and simultaneously, the cleaning plate 56 rotates, causing the cleaning roller 57 to rotate. The cleaning roller 57's revolution drives the contact wheel 58 to rotate, at which point the contact wheel 58 contacts the bottom of the filter plate 410. When the contact wheel 58 rotates, it rotates on its own axis under the contact action at the bottom of the filter plate 410. At this time, the rotation of the contact wheel 58 drives the cleaning roller 57 to rotate. The rotation of the cleaning roller 57 drives the brush to rotate, cleaning the bottom of the filter plate 410 to prevent the accumulation of impurities on the surface of the filter plate 410 and blockage of the filter holes, which would affect the operation and filtration effect and efficiency. Blockage of the filter holes would lead to a decrease in the outflow of water, a sharp drop in filtration efficiency, or even shutdown of the device. This reduces the time and cost of manual maintenance and ensures continuous operation of the device. When the mixing ring 51 moves downward to the bottom under the action of the ozone gas delivery shaft 41, the movement of the mixing ring 51 drives the telescopic connecting rod 53 to move downward. At this time, the movement of the telescopic connecting rod 53 drives the limiting plate 52 to move. At this time, the movement of the telescopic connecting rod 53 releases the limit on the chemical tube 44. At the same time, it briefly increases the instantaneous flow of the inlet pipe 43 to offset the flocculant put into the tank 1 by the chemical tube 44 to achieve the purpose of balance and avoid the water concentration imbalance caused by the addition of flocculant.

[0038] like Figures 1-7As shown, in another embodiment of the present invention, the circumferential surface of the ozone delivery shaft 41 is provided with a defoaming device for eliminating air bubbles inside the tank 1. The defoaming device includes a sleeve ring 61, which is sleeved on the circumferential surface of the ozone delivery shaft 41. A scraper 62 is fixedly installed on the surface of the sleeve ring 61, and a telescopic connecting rod 63 is fixedly installed on the top of the sleeve ring 61. A contact wheel 64 rotatably passes through the surface of a fixed ring 47, and a cam 65 is fixedly installed on the circumferential surface of the contact wheel 64. A contact toothed plate 66 is slidably installed on the surface of the fixed ring 47. A gear 67 is fixedly installed on the circumferential surface of the rotating rod 48, and a telescopic spring rod 68 is fixedly installed on the surface of the fixed ring 47. The contact toothed plate 66 moves toward the telescopic spring rod 68.

[0039] The scraper 62 is rotatably connected to the top of the filter plate 410, and the end of the telescopic connecting rod 63 away from the sleeve ring 61 is fixedly connected to the ozone gas delivery shaft 41. The rotation of the telescopic connecting rod 63 drives the sleeve ring 61 to rotate.

[0040] Contact wheel 64 contacts the inner wall of tank 1, contact tooth plate 66 meshes with gear 67, and fixed ring 47 rotates to drive contact wheel 64 to rotate.

[0041] The end of the contact toothed plate 66 near the cam 65 is provided with an arc surface to assist the cam 65 in receiving force. The free end of the telescopic spring rod 68 is fixedly connected to the end of the contact toothed plate 66 away from the cam 65. The cam 65 rotates to contact and squeeze the contact toothed plate 66 to move.

[0042] In this example, when the mixing ring 51 rotates under the action of the ozone delivery shaft 41, the rotation of the mixing ring 51 is transmitted through the rotation of the telescopic connecting rod 63. Simultaneously, the rotation of the telescopic connecting rod 63 drives the sleeve ring 61 to rotate, which in turn drives the scraper 62 to rotate and clean the top of the filter plate 410. This further improves the cleaning effect and efficiency of the filter plate 410, further reduces the probability of filter pore blockage, extends the service life of the filter plate 410, and reduces the replacement frequency of filter components. At the same time, the fixing ring 47 rotates under the action of the ozone delivery shaft 41, driving the contact wheel 64 to rotate. Because the contact wheel 64 is in contact with the inner wall of the tank 1, the contact wheel 64 revolves under the action of the fixing ring 47. At this time, the contact wheel 64 revolves around the tank 1. The contact wheel 64 rotates under the action of contact with the inner wall, which drives the cam 65 to rotate. At this time, the cam 65 rotates and contacts and squeezes the contact tooth plate 66 to move. The contact tooth plate 66 moves towards the telescopic spring rod 68. Since the contact tooth plate 66 meshes with the gear 67, the movement of the contact tooth plate 66 drives the gear 67 to rotate. At the same time, the rotation of the gear 67 drives the rotating rod 48 to rotate. The rotation of the rotating rod 48 drives the defoaming ring 49 to rotate. At this time, the rotation of the defoaming ring 49 further defoams the bubbles generated when the water inside the tank 1 comes into contact with ozone. Compared with the initial defoaming, the secondary defoaming of the bubbles generated when ozone comes into contact with water can break up the tiny bubbles more effectively, allowing the ozone to be fully released from the bubbles and dissolved into the water, further reducing the ozone emission.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
