Description

Technical Field

[0001] This utility model relates to the field of sealing flange technology, specifically a low-temperature sealing flange for ozone generators. Background Technology

[0002] Ozone, as a strong oxidant, has wide applications in water treatment, air purification, disinfection, and sterilization. An ozone generator is a key piece of equipment for ozone production, and in some special applications, such as high-altitude areas or situations requiring the handling of low-temperature gases, ozone generators need to operate stably in low-temperature environments.

[0003] Traditional sealing flanges often lack a limiting structure for the sealing ring, making it prone to displacement. Furthermore, the sealing rings are made of ordinary rubber, which can lead to decreased sealing performance and material embrittlement at low temperatures. They also lack low-temperature resistance, elasticity, and ozone penetration resistance, resulting in ozone leakage. This not only affects ozone generation efficiency and causes environmental pollution but also poses certain safety hazards. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a low-temperature sealing flange for ozone generators, which has advantages such as resistance to low temperatures and solves the problems mentioned in the background technology.

[0005] To achieve the above-mentioned low-temperature resistance objective, this utility model provides the following technical solution: a low-temperature sealing flange for an ozone generator, including a flange seat, on which multiple connecting columns are installed, and on both sides of the flange seat are connected interfaces, with a first connecting pipe at the front end of the first interface and a second connecting pipe at the rear end of the second interface;

[0006] A sealing ring is provided at the connection between the interface and the first connecting pipe and the second connecting pipe. The sealing ring is made of fluororubber material and is filled with graphene. Multiple notches are provided on the surface of the interface and multiple protrusions are provided on the inner side of the sealing ring. The protrusions are all locked and connected with the notches.

[0007] As a further improvement of this utility model: four threaded seats are provided at the connection points of the first connecting pipe and the second connecting pipe with the interface, and each threaded seat is provided with a fixing bolt. The fixing bolts are all made of high-strength alloy steel, which provides a greater preload under the same tightening force, thereby enhancing the sealing effect.

[0008] As a further improvement of this utility model, the flange seat is made of titanium alloy material, which can maintain good mechanical properties at low temperatures and ensure the overall structural stability of the flange.

[0009] As a further improvement of this invention: a heat insulation layer is provided on the surface of the flange seat. The heat insulation layer is made of aerogel felt, which has extremely low thermal conductivity and good heat insulation performance. It can effectively reduce the influence of the external low temperature environment on the internal temperature of the flange, prevent the sealing performance from decreasing due to excessive temperature gradient, and at the same time, the heat insulation layer can also prevent operators from being frostbitten when contacting the flange, thus improving operational safety.

[0010] As a further improvement of this utility model, the inner wall of the flange seat is provided with a ceramic layer, which can improve the corrosion resistance and stability of the inner wall of the flange seat, and reduce the resistance during fluid flow.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, the protrusions on the surface of the sealing ring are all inserted into the recesses, thereby limiting the sealing ring, improving its stability, preventing displacement, and increasing sealing efficiency. The sealing ring contains graphene, which can improve low-temperature elasticity and ozone penetration resistance, prevent problems such as decreased sealing performance and material embrittlement, prevent ozone leakage, and does not affect the ozone generation efficiency, thus avoiding environmental pollution and preventing safety hazards.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] It should be noted that graphene 11 and aerogel felt are both existing technologies and are common knowledge to those skilled in the art, so they will not be elaborated upon here.

[0021] Please see Figures 1-5 In this embodiment of the utility model, the low-temperature sealing flange for the ozone generator includes a flange seat 1, on which multiple connecting columns 2 are installed. Both sides of the flange seat 1 are connected to interfaces 7. The front end of the front interface 7 is provided with a first connecting pipe 3, and the rear end of the rear interface 7 is provided with a second connecting pipe 5.

[0022] A sealing ring 4 is provided at the connection between the interface 7 and the first connecting pipe 3 and the second connecting pipe 5. The sealing ring 4 is made of fluororubber material and is filled with graphene 11. Multiple recesses 10 are provided on the surface of the interface 7, and multiple protrusions 6 are provided on the inner side of the sealing ring 4. The protrusions 6 are all locked and connected with the recesses 10.

[0023] The connection points of the first connecting pipe 3 and the second connecting pipe 5 with the interface 7 are each equipped with four threaded seats 9. Each threaded seat 9 contains a fixing bolt, which is made of high-strength alloy steel. Under the same tightening force, it provides a greater pre-tightening force, thereby enhancing the sealing effect. The flange seat 1 is made of titanium alloy, which can maintain good mechanical properties at low temperatures, ensuring the overall structural stability of the flange. The surface of the flange seat 1 is provided with a heat insulation layer 12, which is made of aerogel felt. Aerogel felt has extremely low thermal conductivity and good heat insulation performance, which can effectively reduce the influence of the external low temperature environment on the internal temperature of the flange and prevent the sealing performance from decreasing due to excessive temperature gradient. At the same time, the heat insulation layer 12 can also prevent operators from being frostbitten when touching the flange, improving operational safety. The inner wall of the flange seat 1 is provided with a ceramic layer 8, which can improve the corrosion resistance and stability of the inner wall of the flange seat 1 and reduce the resistance to fluid flow.

[0024] The working principle of this utility model is as follows: When the ozone generator operates in a low-temperature environment, the flange seat 1 is made of titanium alloy, which can maintain good mechanical properties at low temperatures, ensuring the overall structural stability of the flange. The protrusions 6 on the surface of the sealing ring 4 are all inserted into the recesses 10, thereby limiting the sealing ring 4, improving the stability of the sealing ring 4, preventing displacement, and improving sealing efficiency. Graphene 11 is provided in the sealing ring 4, which can improve low-temperature elasticity and ozone penetration resistance. The aerogel felt has extremely low thermal conductivity and good heat insulation performance, which can effectively reduce the influence of the external low-temperature environment on the internal temperature of the flange, preventing the sealing performance from decreasing due to excessive temperature gradient. At the same time, the heat insulation layer 12 can also prevent operators from being frostbitten when contacting the flange, improving operational safety. The ceramic layer 8 can improve the corrosion resistance of the inner wall of the flange seat 1, has strong stability, and can reduce the resistance during fluid flow.
