Description

Technical Field

[0001] This utility model relates to the technical field of tin bath auxiliary devices, and more specifically, to a tin bath ventilation guide pipe device. Background Technology

[0002] In glass manufacturing processes, especially in the production of high-quality flat glass using the float glass process, the tin bath plays a crucial role. As one of the core components of the entire production process, the tin bath not only supports the molten glass ribbon under high-temperature conditions but also prevents oxidation caused by contact between the glass and air by providing a protective gas environment composed of nitrogen and hydrogen. This special working environment requires extremely stringent operating conditions, including high temperatures and the presence of a flammable and explosive atmosphere.

[0003] The inert gas environment maintained inside the solder bath is primarily to prevent oxidation of the molten solder and the surface of the glass being formed. This not only affects the quality of the final product but is also a crucial measure to avoid potential safety hazards. To maintain this inert environment, the solder bath needs to be kept under a certain positive pressure to prevent the infiltration of outside air, thereby avoiding the risk of oxidation or explosion of the molten solder due to oxygen entry.

[0004] However, existing solder bath pressure relief devices typically rely on simple valves for pressure regulation. While these traditional valves can meet basic pressure relief requirements, their sealing performance is often unsatisfactory, leading to potential media leakage. Furthermore, due to their relatively basic design, these valves may not provide sufficient accuracy and response speed to effectively manage pressure changes within the solder bath under complex and variable operating conditions. These problems can not only lead to decreased production efficiency but, more seriously, may pose a threat to plant safety, increasing the risk of fire or explosion. Utility Model Content

[0005] The purpose of this utility model is to provide a tin bath ventilation guide pipe device to solve the technical problem that leakage is easy to occur during the current tin bath depressurization process.

[0006] This utility model provides a tin bath ventilation guide pipe device, comprising: a tin bath body, having a receiving cavity for accommodating glass; a guide pipe body, disposed on the tin bath body, having a guide channel communicating with the receiving cavity; and a sealing assembly, disposed between the guide pipe body and the tin bath body, to seal the connection between the guide pipe body and the tin bath body.

[0007] According to one embodiment of the present invention, the sealing assembly includes a first ring plate and a second ring plate that are spaced apart from and surround the outside of the guide tube body. The first ring plate and the second ring plate are spaced apart and extend in a vertical direction. A sealing material is filled between the first ring plate, the second ring plate, the guide tube body and the groove body.

[0008] According to one embodiment of the present invention, the sealing material is water. According to one embodiment of the present invention, the guide pipe body includes a main pipe section and a first secondary pipe section with an angle, and the main pipe section is connected to the tank body.

[0009] According to one embodiment of the present invention, an isolation member is provided between the main pipe section and the first secondary pipe section. The wall of the first secondary pipe section is provided with a hinge base. One end of the isolation member is hinged to the hinge base and can rotate along the hinge position. When the isolation member is in the first working position, the first secondary pipe section and the main pipe section are isolated. When the isolation member is in the second working position, the first secondary pipe section and the main pipe section are connected.

[0010] According to one embodiment of the present invention, a second auxiliary pipe section is further included, with its angle set at the main pipe section.

[0011] According to one embodiment of the present invention, the second auxiliary pipe section is provided with a rupture disc.

[0012] According to one embodiment of the present invention, the guide tube body and the sealing assembly are provided in a one-to-one correspondence, and multiple sets are provided.

[0013] The technical solution of this utility model has at least the following advantages and beneficial effects:

[0014] The technical advantage of this invention is that it provides a tin bath ventilation guide pipe device that effectively seals the connection between the guide pipe and the tin bath body, ensuring that the gas inside the tin bath body does not leak to the outside from the connection point. It also prevents external air from entering the tin bath body and causing oxidation, prevents the leakage of internal protective gas, and maintains the required inert environment. Simultaneously, by setting an angled main pipe section and two auxiliary pipe sections, combined with the use of an isolator and a rupture disc, the device can adjust the flow according to changes in system pressure. When the pressure is too high, the isolator moves to a second position, connecting the main pipe section and the first auxiliary pipe section, thereby further guiding the gas in the system to the outside of the tin bath body.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0026] Example 1

[0027] This utility model provides a tin bath ventilation guide pipe device to increase the sealing between the tin bath and the pressure relief structure, thereby further ensuring the pressure relief effect.

[0028] Please see Figure 1The tin bath ventilation guide pipe device provided in this embodiment includes: a tank body 100, which is provided with a receiving cavity for accommodating glass. In this embodiment, the tank body 100 is used to accommodate molten glass and support its molding under high temperature conditions. The interior is maintained in an environment filled with protective gas (nitrogen and hydrogen) to prevent glass oxidation.

[0029] A guide tube body is provided on the tank body 100 and has a guide channel communicating with the receiving cavity. In this embodiment, the guide tube body is provided on the top of the tank body 100.

[0030] A sealing assembly is disposed between the flow guide tube and the tank body 100 to seal the connection between the flow guide tube and the tank body 100, ensuring that the connection between the flow guide tube and the tank body 100 is sealed and preventing external air from entering and causing oxidation of the molten solder or leakage of internal protective gas.

[0031] In this embodiment, the sealing assembly includes a first ring plate 301 and a second ring plate 302 that are spaced apart from the flow guide tube and surround the outside of the flow guide tube. The first ring plate 301 and the second ring plate 302 are spaced apart and extend in the vertical direction. The space between the first ring plate 301, the second ring plate 302, the flow guide tube and the groove body 100 is filled with sealing material.

[0032] In this embodiment, the sealing material is water. According to one embodiment of the present invention, the guide pipe body includes a main pipe section 201 with an angle and a first secondary pipe section 202, and the main pipe section 201 is connected to the tank body 100.

[0033] In this embodiment, an isolation member 204 is provided between the main pipe section 201 and the first secondary pipe section 202. The pipe wall of the first secondary pipe section 202 is provided with a hinged base 2041. One end of the isolation member 204 is hinged to the hinged base 2041 and can rotate along the hinge position. When the isolation member 204 is in the first working position, the first secondary pipe section 202 and the main pipe section 201 are isolated. When the isolation member 204 is in the second working position, the first secondary pipe section 202 and the main pipe section 201 are connected. In this embodiment, when the isolation member 204 is in the first working position, the isolation member 204 is in a vertical state and the other end abuts against the pipe wall of the first secondary pipe section 202. The relative position is stabilized by friction. When the pressure increases, the isolation member 204 rotates along the hinge position and moves to the second working position, so that the main pipe section 201 and the first secondary pipe section 202 are connected, and excess gas is discharged.

[0034] In this embodiment, a second auxiliary pipe section 203 with an angle set at the main pipe section 201 is also included.

[0035] In this embodiment, the second auxiliary pipe section 203 is provided with a rupture disc 400. The second auxiliary pipe section 203 and the main pipe section 201 are separated by the rupture disc 400. The rupture disc 400 automatically ruptures under a set pressure, allowing gas to be quickly discharged through the second auxiliary pipe section 203. In this embodiment, the first auxiliary pipe section 202 is below the second auxiliary pipe section 203.

[0036] The following is a detailed description of the usage process of the tin bath ventilation guide pipe device in Embodiment 1 of this utility model:

[0037] During use, the sealing component ensures the airtightness of the entire system, preventing outside air from entering or internal protective gas from leaking. When the pressure inside the system exceeds the normal range, the isolator 204 moves from the first station to the second station, connecting the main pipe section 201 with the first auxiliary pipe section 202 to help release excess gas. If the system pressure continues to rise to a dangerous level, the rupture disc 400 will automatically rupture, quickly releasing the pressure through the second auxiliary pipe section 203 to avoid potential safety accidents.

[0038] Example 2

In this embodiment, a rupture disc 400 is provided inside the emergency discharge port 500. When the internal pressure of the system reaches a dangerous level, the rupture disc 400 will automatically rupture, allowing the gas to be released quickly through the emergency discharge port 500, thereby effectively preventing potential risks caused by excessive pressure, such as equipment damage or safety accidents.

[0044] The embodiments of this utility model have at least the following advantages:

[0045] The technical advantage of this invention is that it provides a tin bath ventilation guide pipe device that effectively seals the connection between the guide pipe and the tin bath body, ensuring that the gas inside the tin bath body does not leak to the outside from the connection point.
