Technical Field
[0001] This utility model belongs to the field of air purification technology, and in particular relates to an ozone system anti-backflow device. Background Technology
[0002] This section describes the closest existing technology, which can be divided into two aspects: broad background technology and specific background technology. The broad background technology mainly refers to the overall situation of the technical field, while the specific background technology refers to the technical situation closely related to the specific technology improved by this invention. The level of detail in the background technology should be such that the technical situation closely related to the technology can be understood without referring to the literature. If the prior art comes from patent literature, journals, or books, the source should be provided.
[0003] As ozone applications continue to expand and the requirements for equipment stability increase, there is a need for more reliable and efficient backflow prevention devices. For example, in water treatment in the pharmaceutical industry, where water quality requirements are extremely high, it is not only necessary to prevent backflow, but also to monitor and treat backflow to ensure the safety and stability of the entire system. At the same time, in large-scale wastewater treatment plants and other application scenarios, backflow prevention devices are required to be able to adapt to greater flow and pressure changes, and have lower maintenance costs and higher automation. Therefore, an ozone system backflow prevention device has been launched.
[0004] Existing ozone systems use one-way valves or anti-backflow solenoid valves for backflow prevention. After long-term use, the sealing elements are prone to aging or damage. Even in a closed state, backflow may occur. This will cause the ozone gas already added to the water to be carried back to the ozone generator by the backflow, resulting in moisture damage to the ozone generator. At the same time, it will reduce the amount of ozone actually added to the target water body, thus reducing the disinfection effect.
[0005] Traditional ozone system backflow prevention equipment is prone to damage from moisture during use, which affects the disinfection effect of the ozone system. Utility Model Content

[0029] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.
[0030] Example 1
[0031] This utility model provides an ozone system backflow prevention device, such as... Figures 1 to 5As shown, the system includes: a cylindrical barrel 1, a sealing plate 2, reducers 3, clamps 4, and a detection element 5. The cylindrical barrel 1 is made of stainless steel and contains a cleaning assembly. The sealing plate 2 is connected to the cylindrical barrel 1 and is circular with a circular groove at its center. The sealing plate 2 is located above the cylindrical barrel 1. The reducers 3 are connected to the cylindrical barrel 1 and are located below it. The reducers 3 are tapered, tapering from top to bottom, and are used to guide the gas discharged from the cylindrical barrel 1. Multiple clamps 4 are connected to the cylindrical barrel 1, and each clamp 4 has a sealing gasket or other sealing structure at its connection point with the cylindrical barrel 1. The detection element 5 is connected to the cylindrical barrel 1 via the clamps 4 and is a liquid level sensor. When water vapor comes into contact with the detection element 5, the automatic valve of the detection element 5 is activated to achieve automatic drainage, preventing water from entering the ozone generator unit and damaging electrical components.
[0032] An existing ozone system backflow prevention device also includes ozone inlet and ozone outlet structures. During use, ozone enters the inside of the cylinder 1 through the ozone inlet and is discharged through the ozone outlet. All of the above are existing technologies and will not be described in detail here.
[0033] By linking the detection component 5 with the automatic valve, the internal pressure change of the ozone generator caused by backflow can be effectively avoided, preventing ozone from leaking into the surrounding environment from weak points such as the connection between the generator and the pipeline, ensuring the health and safety of operators, and reducing the safety risks such as poisoning and fire that may be caused by ozone leakage.
[0034] During use, ozone gas enters the cylinder 1 through the ozone inlet and is output to the application end through the ozone outlet. Then, the water level rise signal is detected by the detection element 5. When water vapor comes into contact with the detection element 5, the automatic valve of the detection element 5 is activated to realize the automatic drainage function, preventing water from entering the ozone generator unit and damaging electrical components. It can effectively avoid pressure changes inside the ozone generator caused by backwater and prevent ozone from leaking into the surrounding environment from weak points such as the connection between the generator and the pipeline, thus protecting the health and safety of operators. The linkage between the detection element 5 and the automatic valve reduces the safety risks such as poisoning and fire that may be caused by ozone leakage.
[0035] In the above example, the sealing plate 2 is welded to the top of the barrel 1, the reducer 3 is welded to the bottom of the barrel 1, the clamp 4 is clamped to the outer surface of the barrel 1, and the test piece 5 is installed on the outer surface of the barrel 1 through the clamp 4.
[0036] To enable the device to simultaneously clean the inner wall of cylinder 1 during operation, such as... Figures 3 to 5As shown, the cleaning assembly includes: a drive assembly, a mounting bracket 6, a rotating shaft 7, a scraper assembly 8, and a transmission component 9. The mounting bracket 6 is connected to the inside of the cylindrical barrel 1. The mounting bracket 6 is cross-shaped, and a bearing is provided at the intersection of the cross-shaped mounting brackets 6. There are two mounting brackets 6. The rotating shaft 7 is connected to the bearing at the intersection of the cross-shaped mounting brackets 6. The scraper assembly 8 is connected to the rotating shaft 7. Triangular fixing rods are fixedly connected to the top and bottom of the scraper assembly 8, and the triangular fixing rods are fixedly connected to the surface of the rotating shaft 7 for cleaning the inner wall of the cylindrical barrel 1. The cleaning process involves the scraper assembly 8 fitting snugly against the inner wall of the barrel 1. A transmission component 9 is connected to the rotating shaft 7. Through the cooperation of these components, the scraper assembly 8 rotates tightly against the inner wall of the barrel 1. The drive assembly includes a positioning frame 16, a connecting rod 10, a baffle 11, and a transmission component 12. The positioning frame 16 is connected to the barrel 1 and is used to position the drive structure. The connecting rod 10 is connected to the mounting frame 6. Two scraper assemblies 8 are provided, located on the upper and lower sides of the connecting rod 10 respectively. The baffle 11 is connected to the connecting rod 10. Three baffles 11 are provided, arranged in a circular array around the center of the side of the connecting rod 10, to block and guide the water flow. A second transmission component 12 connects the first transmission component 9 and the connecting rod 10. Both the first and second transmission components 9 are bevel gears. Two first transmission components 9 are provided, meshing with the surface of the second transmission component 12. When the connecting rod 10 rotates, the cleaning assembly is driven by the cooperation of the second transmission component 12 and the first transmission component 9. The two transmission components 9 are provided with the same positioning rod 13 on the side that is close to each other. The positioning rod 13 is provided with a positioning plate 14. The positioning plate 14 is provided with a shell 15. The shell 15 encloses the connection between the transmission component 9 and the transmission component 12. The connection between the shell 15 and the connecting rod 10 and the rotating shaft 7 is provided with a sealing structure to prevent water vapor inside the cylinder 1 from adhering to the surface of the transmission component 9 and the transmission component 12. The baffle 11 is shaped to be inclined around the connecting rod 10, so that the flowing liquid rotates along the inclined surface of the baffle 11.
[0037] When the liquid inside the cylindrical barrel 1 is discharged, the scraper assembly 8 rotates against the inner wall of the cylindrical barrel 1, which effectively cleans the inner wall of the cylindrical barrel 1, thereby effectively reducing the impurities remaining on the surface of the cylindrical barrel 1 and improving the cleanliness of the inside of the cylindrical barrel 1.
[0038] When in use, the liquid flows along the surface of the baffle 11 when it is discharged, causing the baffle 11 to rotate. The baffle 11 drives the connecting rod 10 to rotate, the connecting rod 10 drives the transmission component 2 12 to rotate, the transmission component 2 12 drives the transmission component 1 9 to rotate, the transmission component 1 9 drives the rotating shaft 7 to rotate, and the rotating shaft 7 drives the scraper assembly 8 to rotate. When the scraper assembly 8 rotates, it removes the impurities remaining on the inner wall of the barrel 1, which can effectively prevent the accumulation of dirt, sediment or microorganisms, thereby avoiding the problem of blockage inside the barrel 1 due to excessive impurities, and thus extending the service life of the device.
[0039] In the above example, the mounting bracket 6 is fixedly connected to the top and bottom of the cylinder 1. The mounting brackets 6 at the top and bottom are both connected to the rotating shaft 7 by bearing interference fit. The outer surfaces of the two rotating shafts 7 are fixedly connected to the scraper assembly 8. The surface of the scraper assembly 8 is in contact with the inner wall of the cylinder 1. The end faces of the two rotating shafts 7 that are close to each other are fixedly connected to the transmission component 9. The outer surface of the transmission component 9 is meshed with the transmission component 12. The end face of the transmission component 12 is fixedly connected to the connecting rod 10. The outer surface of the connecting rod 10 is fixedly connected to multiple baffles 11. The edge of the outer surface of the connecting rod 10 is rotatably connected to the positioning bracket 16. The two positioning brackets 16 are fixedly connected to the inside of the cylinder 1. The opposite end faces of the two transmission components 9 are rotatably connected to the same positioning rod 13. The middle of the outer surface of the positioning rod 13 is rotatably connected to the positioning plate 14. The end face of the positioning plate 14 is fixedly connected to the outer shell 15.
[0040] Working Principle: During operation, ozone gas enters the cylinder 1 through the ozone inlet and exits to the application end through the ozone outlet. The device then detects a rise in water level using detector 5. When water vapor comes into contact with detector 5, the automatic valve of detector 5 is activated, enabling automatic drainage to prevent water from entering the ozone generator unit and damaging electrical components. This effectively avoids pressure changes inside the ozone generator caused by backflow and prevents ozone leakage from weak points such as the connection between the generator and pipes into the surrounding environment, ensuring the health and safety of operators. The linkage between detector 5 and the automatic valve reduces the safety risks of poisoning and fire caused by ozone leakage, and minimizes the risk of gas leakage from weak points in the cylinder 1's connection and seals. This ensures that ozone gas is strictly controlled within a closed system, preventing environmental pollution.
[0041] When the liquid is discharged, it first flows along the surface of the baffle 11, causing the baffle 11 to rotate. The baffle 11 drives the connecting rod 10 to rotate, the connecting rod 10 drives the transmission component 2 12 to rotate, the transmission component 2 12 drives the transmission component 1 9 to rotate, the transmission component 1 9 drives the rotating shaft 7 to rotate, and the rotating shaft 7 drives the scraper assembly 8 to rotate. When the scraper assembly 8 rotates, it removes the impurities remaining on the inner wall of the cylinder 1, which can effectively prevent the accumulation of dirt, sediment or microorganisms, thereby avoiding the problem of blockage inside the cylinder 1 due to excessive impurities, and thus extending the service life of the device.
[0042] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
