[0003] In the glass production process, glass kilns are designed with observation ports so that operators can observe the glass production status inside the kiln. The original design used to seal these observation ports by directly inserting sealing bricks into them.

[0004] In the existing technology, the volatiles generated by the high-temperature flue gas of the kiln are easy to adhere and accumulate on the inner wall of the observation port. After long-term operation, the sealing of the observation port is easily affected. When the operator is observing the furnace condition, the high-temperature flames that spray out after opening the sealing brick can easily burn the operator, and the safety of the operation cannot be guaranteed, such as CN205784659U. Utility Model Content

[0005] One of the technical problems this application aims to solve is that when observing the inside of a glass furnace, there is a problem of poor sealing caused by volatile matter in the flue gas adhering to the observation port.

[0009] In some embodiments, the sealing assembly has a connection structure on the side away from the outlet assembly, the connection structure having a through hole, and the observation port sealing device further includes a handle assembly detachably connected to the through hole.

[0010] In some embodiments, the length of the handle assembly is 0.9m to 1.2m.

[0013] In some embodiments, the recovery assembly includes an air intake structure and a settling chamber, with a first end of the air intake structure corresponding to a second end of the outlet assembly, and the second end of the air intake structure communicating with the settling chamber.

[0014] In some embodiments, the connection between the sealing component and the outlet component is located at the upper edge of the outlet component, and the observation port sealing device further includes a drive component that is rotatably connected to the connection structure.

[0015] In some embodiments, the drive assembly includes a drive motor structure, a drum structure, and a wire rope. The wire rope is wound around the drum structure, the output end of the drive motor structure is connected to the drum structure, and one end of the wire rope passes through a through hole and is knotted.

[0016] According to another aspect of this application, a glass furnace is also provided. The glass furnace adopts the above-mentioned observation port sealing device.

[0033] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0034] like Figures 1 to 3As shown, the observation port sealing device disclosed in Embodiment 1 of this application includes: a mounting base assembly 10, an outlet assembly 20, a sealing assembly 30, and an air outlet assembly 40. The mounting base assembly 10 has an opening structure 11 corresponding to the observation port. The first end of the outlet assembly 20 is connected to the opening structure 11. The sealing assembly 30 is rotatably connected to the second end of the outlet assembly 20. The sealing assembly 30 has a sealing state close to the outlet assembly 20 and a waiting-to-be-sealed state away from the outlet assembly 20. The air outlet end of the air outlet assembly 40 is correspondingly provided to the second end of the outlet assembly 20.

[0035] Applying the technical solution of Embodiment 1, the mounting base assembly 10 is installed on the outer wall of the glass furnace, so that the opening structure 11 is correspondingly set with the observation port. When it is not necessary to observe the inside of the glass furnace, the sealing assembly 30 seals the end face of the observation port to prevent flue gas from overflowing. When it is necessary to observe the inside of the glass furnace, the sealing assembly 30 is rotated to put it in the ready-to-seal state, and the venting assembly 40 vents gas, reducing the amount of volatiles in the flue gas adhering to the observation port. Furthermore, since the sealing assembly 30 seals the end face of the observation port, the adhering of volatiles to the side wall of the observation port will not affect the sealing performance of the sealing assembly 30. The technical solution of Embodiment 1 effectively solves the problem of poor sealing caused by the adhering of volatiles in the flue gas to the observation port when observing the inside of the glass furnace in the prior art.

[0036] It should be noted that the exhaust assembly 40 includes an air source, an exhaust pipe, and a valve. The air source provides compressed air, and the exhaust pipe is located on one side of the outlet assembly 20. When the valve is opened, compressed air is ejected from the exhaust pipe, thereby changing the direction of the flue gas flow at the outlet assembly 20. This prevents high-temperature flue gas from directly ejecting and obstructing the staff's vision when they are observing through the observation port, and also avoids the staff from being easily burned.

[0037] like Figure 2 As shown, in the technical solution of Embodiment 1, the distance between the second end of the outlet component 20 and the mounting base component 10 gradually decreases from bottom to top along the vertical direction. When the sealing component 30 is in the sealing state, it is fitted against the second end of the outlet component 20. That is, the end face of the second end of the outlet component 20 has an angle with the vertical direction. Therefore, when it is not necessary to observe the internal condition of the glass furnace, the sealing component 30 is pressed against the end face of the second end of the outlet component 20 under the action of gravity, preventing flue gas from overflowing, ensuring good sealing performance, and requiring no additional external force, thus saving manpower and material resources.

[0038] like Figures 1 to 3As shown, in the technical solution of Embodiment 1, the sealing component 30 has a connecting structure 31 on the side away from the outlet component 20. The connecting structure 31 has a through hole 311. The observation port sealing device also includes a handle assembly 50, which is detachably connected to the through hole 311. When the operator needs to observe the inside of the glass furnace, the handle assembly 50 is inserted into the through hole 311, and external force is applied to the connecting structure 31 to rotate the sealing component 30, exposing the observation port 002 for observation. After observation, the sealing component 30 is rotated again to seal the observation port 002. After sealing, the handle assembly 50 is removed. The handle assembly 50 avoids the problem of operators being burned by high temperatures from direct contact with the sealing component 30.

[0039] like Figure 3 As shown, in the technical solution of Embodiment 1, the length of the handle assembly 50 is 0.9m to 1.2m. The handle assembly 50 includes a first connecting section and a second connecting section, which are connected to each other. The first connecting section is cylindrical, and the second connecting section is L-shaped, U-shaped, or hook-shaped, etc. During use, the operator holds the first connecting section, inserts the second connecting section into the through hole 311, and pulls the first connecting section to open the sealing assembly 30. The total length of the first and second connecting sections is the length of the handle assembly 50. Because the temperature inside the glass furnace is high, the observation port sealing device fixed on the glass furnace is also at a high temperature due to prolonged exposure to high temperatures. To prevent operators from being burned during operation, the length of the handle assembly 50 determines the distance between the operator and the glass furnace during operation. When the length of the handle assembly 50 is less than 0.9m, the distance between the operator and the glass furnace is small during operation, making the operator susceptible to burns. When the length of the handle assembly 50 is greater than 1.2m, operation is more strenuous, and the handle assembly 50 is prone to bending and deformation.

[0040] like Figure 1 and Figure 2 As shown, in the technical solution of Embodiment 1, the connection between the sealing component 30 and the outlet component 20 is located at the lower edge of the outlet component 20. The sealing component 30 and the outlet component 20 are connected by a hinge, which can be implemented using a hinge or similar structure. When opening the sealing component 30, after rotating the sealing component 30 to a certain angle, the handle component 50 can be released. The sealing component 30 will not close under the action of gravity. After observation is completed, the handle component 50 can be operated again. After closing, the handle component 50 can be removed. This operation method is relatively labor-saving, and there is no need to operate the handle component 50 during the observation process, which is quite labor-saving.

[0041] like Figure 4As shown, the difference between the technical solution of Embodiment 2 and Embodiment 1 is that the connection between the sealing component 30 and the outlet component 20 is located at the upper edge of the outlet component 20. The observation port sealing device also includes a drive component 60, which is rotatably connected to the connecting structure 31. In Embodiment 2, since the connection between the sealing component 30 and the outlet component 20 is located at the upper edge of the outlet component 20, in order to prevent the sealing component 30 from closing during observation, the drive component 60 needs to continuously apply external force to the sealing component 30 to prevent it from closing.

[0042] like Figure 4 As shown, in the technical solution of Embodiment 2, the driving component 60 includes a driving motor structure 61, a roller structure 62, and a steel wire rope 63. The steel wire rope 63 is wound around the roller structure 62. The output end of the driving motor structure 61 is connected to the roller structure 62, and one end of the steel wire rope 63 passes through the through hole 311 and is knotted. The driving motor structure 61 drives the roller structure 62 to rotate, thereby changing the winding length of the steel wire rope 63, and thus controlling the rotation of the sealing component 30. The technical solution of Embodiment 2 can realize the automatic opening and closing of the sealing component 30, eliminating the need for manual operation by personnel and further preventing personnel from being burned by high temperatures.

[0043] The difference between the technical solution of Embodiment 3 and that of Embodiment 1 is that the observation port sealing device further includes a recovery component, and the recovery component and the exhaust component 40 are respectively arranged on both sides of the outlet component 20. The recovery component is used to recover the overflowing high-temperature flue gas, preventing a large amount of flue gas from flowing into the air and causing pollution.

[0044] In the technical solution of Embodiment 3, the recovery component includes an intake structure and a settling chamber. The first end of the intake structure corresponds to the second end of the outlet component 20, and the second end of the intake structure is connected to the settling chamber. The intake structure draws in the flue gas and discharges it into the settling chamber. The settling chamber has a spray structure that sprays quicklime solution and other substances to react with the high-temperature flue gas, absorbing sulfides and other substances inside the flue gas, which then settle inside the settling chamber, preventing harmful gases from being emitted into the air. The outlet component 40 also includes a laser sensor near the outlet component 20. The laser sensor is connected to the outlet pipeline and emits a laser to the sealing component 30. When the laser sensor detects that the sealing component 30 is open, the outlet component 40 and the recovery component work simultaneously, allowing the high-temperature flue gas to enter the settling chamber.

[0045] According to another aspect of this application, a glass furnace is also provided. The glass furnace employs the aforementioned observation port sealing device. The glass furnace includes a furnace body 001 and an observation port 002. The observation port 002 penetrates the furnace body 001. The mounting base assembly 10 is connected to the furnace body 001, and the opening structure 11 is connected to the observation port 002. By opening the sealing assembly 30, the operator's line of sight sequentially passes through the outlet assembly 20, the opening structure 11, and the observation port 002 to observe the interior of the glass furnace, ensuring the stability of the internal process.

[0046] In summary, this application is primarily used for observing the condition of glass kilns. In the original design, the observation port 002 was sealed directly with a sealing brick. However, volatile substances generated by the high-temperature flue gas in the kiln tend to adhere and accumulate at the interface between the sealing brick and the observation port, which can affect the sealing performance of the observation port after prolonged operation. Furthermore, when operators observe the furnace, opening the sealing brick can cause burns from the high-temperature flames, compromising operational safety. To address these issues, this application proposes an improved safety sealing device for the observation port, which ensures both the sealing performance of the observation port and prevents burns from the high-temperature flames, thus improving operational safety. In this application, bolts and wing nuts are used to pass through bolt holes and bolt fixing holes to fix the component base (mounting base assembly 10 and outlet assembly 20) to the observation port brick. The component flip cover (sealing assembly) is connected to the component base by fixing bolts. A self-made iron hook (handle assembly 50) is used to open and close the component flip cover by passing through the flip cover hook ring (connection structure 31). A compressed air pipe (air outlet assembly 40) is installed next to the component base. Compressed air is opened and closed by the compressed air pipe valve to deflect the high-temperature flame away from the observer's direct line of sight. The specific implementation method is as follows: when it is necessary to observe the furnace condition, the compressed air valve is opened to blow high-pressure air out of the compressed air pipe. Then, the self-made iron hook is used to pull down through the flip cover hook ring to open the component flip cover, blowing the high-temperature flame away from the observation port, and then the furnace condition is observed. After the observation is completed, the self-made iron hook is used to push up through the flip cover hook ring to close the component flip cover and seal the observation port brick. Finally, the compressed air valve is closed to end the furnace condition observation operation. This application relates to maintaining the airtightness of the kiln observation port during kiln production operations, ensuring personnel safety during kiln condition observation, and preventing burns from the high-temperature flames inside the kiln. The device features a high-temperature resistant stainless steel component with a sloping, downward-opening cover. Its base is bolted to the surface of the observation port brick, and a compressed air pipe is connected to the side of the component. When not observing the kiln, the cover is firmly secured to the base under its own weight, maintaining the airtightness of the observation port. When observation is needed, the cover is opened and closed using a homemade iron hook approximately 1 meter long, simultaneously opening the compressed air valve to deflect the high-temperature flames away from the front of the observation port, thus achieving safe observation of the kiln condition. All components and bolts used in this application are made of high-temperature resistant 316S stainless steel, the homemade iron hook is made of 304 stainless steel, and the observation port brick is made of high-strength, high-temperature resistant, and corrosion-resistant 41#AZS refractory brick.
