[0036] Reference below Figure 1-Figure 6 The glass melting furnace observation hole sealing structure 100 and the glass melting furnace according to the embodiment of the present utility model are described.

[0037] like Figure 1-Figure 2 As shown, the glass melting furnace observation hole sealing structure 100 according to the first aspect of the embodiment of the utility model comprises a furnace wall 1 and an observation hole 11 opened on the furnace wall 1 .

[0038] The glass melting furnace observation hole sealing structure 100 further includes a flange 12 and an observation hole cover 2 .

[0039] The flange 12 is arranged around the observation hole 11, one end of the flange 12 is fixedly connected to the furnace wall 1, and the other end of the flange 12 extends outward in a direction away from the furnace wall 1. The outward extension here means that the flange 12 extends to the outside of the cavity of the glass melting furnace, rather than extending into the cavity of the glass melting furnace.

[0040] The observation hole cover 2 can cover the observation hole 11. The observation hole cover 2 has a first surface facing the observation hole 11 and a second surface away from the observation hole 11. The first surface has a groove 22 recessed toward the second surface, and the first holding portion 21 is fixed on the second surface.

[0041] The observation hole cover 2 has a closed position and an open position. When the observation hole cover 2 is in the closed position, the observation hole cover 2 covers the observation hole 11, and the end surface of the flange 12 abuts against the bottom of the groove 22; when the observation hole cover 2 is in the open position, the observation hole cover 2 is separated from the observation hole 11; the groove width L22 of the groove 22 is greater than the thickness L12 of the flange 12.

[0042] When in use, the observation hole cover 2 is placed on the observation hole 11, and the end face of the flange 12 abuts against the bottom of the groove 22. The observation hole cover 2 and the flange 12 together seal the kiln wall 1, thereby improving the sealing of the kiln and reducing the heat escape from the observation hole 11.

[0043] When it is necessary to open the observation hole 11 to observe the glass liquid in the furnace, the observation hole cover 2 can be driven away from the observation hole 11 by holding the first holding portion 21, which is beneficial to reduce the probability of being burned when directly contacting the observation hole cover 2 and improve safety and convenience.

[0044] It should be further explained that when the glass melting furnace is melting glass, the temperature of the side of the furnace wall 1 facing the furnace cavity is higher, the temperature distribution on the furnace wall 1 is uneven, and local deformation is easy to occur. In the present application, the other side of the flange 12 is extended outward in the direction away from the furnace wall 1 to reduce the influence of high temperature in the furnace and reduce the size of deformation; the groove width L22 of the groove 22 is larger than the thickness L12 of the flange 12, which is conducive to the flange 12 still being able to fit into the groove 22 under the condition of flange 12 deformation, thereby improving the sealing of the furnace.

[0045] The groove 22 is arranged on the observation hole cover 2, and the observation hole cover 2 can be removed to clean and scrape the solid formed by condensation of the alkali vapor in the groove 22 of the observation hole cover 2.

[0046] According to the glass melting furnace observation hole sealing structure 100 of the embodiment of the present application, the observation hole cover 2 is provided on the observation hole 11, and the end face of the flange 12 abuts against the bottom of the groove 22. The observation hole cover 2 and the flange 12 jointly seal the furnace wall 1, thereby improving the sealing performance of the furnace and helping to reduce the heat from escaping from the observation hole 11. When in use, the glass melting furnace melts the glass, and the temperature of the side of the furnace wall 1 facing the furnace cavity is higher. The other end of the flange 12 is extended outward in a direction away from the furnace wall 1 to reduce the influence of the high temperature in the furnace and reduce the size of the deformation; the groove width L22 of the groove 22 is larger than the thickness L12 of the flange 12, which is conducive to the flange 12 still being able to fit into the groove 22 under the condition of the flange 12 being deformed, thereby ensuring the sealing performance of the glass melting furnace.

[0047] like Figure 2-Figure 3As shown, in some embodiments, the flange 12 includes an upper flange 121 and a lower flange 123 arranged opposite to each other in the up-down direction, and the distance that the upper flange 121 protrudes from the kiln wall 1 is less than the distance that the lower flange 123 protrudes from the kiln wall 1; the flange 12 also includes two second flanges 122 arranged opposite to each other, and the two second flanges 122 are arranged on the side edges of the observation hole 11, and each second flange 122 is arranged between the upper flange 121 and the lower flange 123 and is gradually inclined from top to bottom. That is to say, the flange 12 is gradually inclined from top to bottom, and the distance that the lower flange 123 protrudes from the kiln wall 1 is relatively large, and the observation hole cover 2 can abut against the flange 12 under the action of its own gravity, thereby improving the sealing performance and structural stability.

[0048] like Figure 1-Figure 2 As shown, in some embodiments, the observation hole cover 2 is rotatably connected to the kiln wall 1 and is located on the upper side of the upper flange 121. When the observation hole cover 2 is opened, the first holding portion 21 drives the observation hole cover 2 to flip and expose the observation hole 11; when closed, the holding force of the first holding portion 21 is canceled, and the observation hole cover 2 covers the observation hole 11 under the action of its own gravity, thereby improving the convenience and reliability of the sealing structure.

[0049] like Figure 1-Figure 2 , Figure 4-Figure 6 As shown, in some embodiments, the first gripping portion 21 is located at the lower side of the groove 22. In combination with the above embodiments, the observation hole cover 2 is rotatably connected to the kiln wall 1 and is located at the upper side of the upper flange 121. The observation hole cover 2 is folded with the upper side of the groove 22 as a fulcrum. The first gripping portion 21 is arranged at the lower side of the groove 22, which can reduce the opening force of the observation hole cover 2 and improve the convenience of opening and closing.

[0050] like Figure 1-Figure 2 As shown, Figure 4-Figure 6 In some embodiments shown, two brackets 13 are spaced apart above the observation hole 11 of the kiln wall 1, and the observation hole cover 2 is hinged between the two brackets 13 through a rotating shaft 23. The observation hole cover 2 is supported by multiple brackets 13, and the connection structure is simple and highly reliable.

[0051] like Figure 1-Figure 3 As shown, in some embodiments, the bracket 13 has a first arm 131 and a second arm 132 that are arranged at intervals and extend upward, and the rotating shaft 23 is clamped between the first arm 131 and the second arm 132. During assembly, the rotating shaft 23 is installed from the opening between the first arm 131 and the second arm 132, which is simple and convenient to assemble, thereby improving the convenience of use.

[0052] like Figure 1-Figure 2 , Figure 4-Figure 6As shown, for example, both axial ends of the rotating shaft 23 are provided with limiting parts, and the diameter of the limiting parts is larger than the size of the interval between the first arm 131 and the second arm 132, which is beneficial to improve the stability and reliability of the rotating shaft 23 installed on the bracket 13.

[0053] like Figure 1 As shown, in some embodiments, the first holding portion 21 is connected to the second holding portion 5 through a flexible member, and the second holding portion 5 is spaced apart from the kiln wall 1. Pulling the second holding portion 5 can drive the observation hole cover 2 to open the observation hole 11. Since the second holding portion 5 is spaced apart from the kiln wall 1, the second holding portion 5 can be manually held and the observation hole cover 2 can be frequently opened, thereby improving the convenience of use.

[0054] like Figure 1 As shown, in some embodiments, a pulley 3 bracket 13 is fixedly connected above the observation hole 11 of the kiln wall 1, a pulley 3 is provided on the pulley 3 bracket 13, a steel cable 4 is sleeved on the pulley 3, one end of the steel cable 4 is connected to the first holding portion 21, and the other end of the steel cable 4 is connected to the second holding portion 5. By providing the pulley 3, the pulling direction of the steel cable 4 can be changed, so that the second holding portion 5 can be pulled in the up and down direction, further improving the convenience of use.

[0055] In some embodiments, the viewing hole cover 2 is a cast iron piece, and the viewing hole cover 2 can have a relatively high strength.

[0056] The glass melting furnace according to the embodiment of the second aspect of the utility model comprises the glass melting furnace observation hole sealing structure 100 according to the embodiment of the first aspect of the utility model.

[0057] According to the glass melting furnace of the embodiment of the present application, by setting the above-mentioned glass melting furnace observation hole sealing structure 100, the observation hole cover 2 is set on the observation hole 11, and the end face of the flange 12 abuts against the bottom of the groove 22. The observation hole cover 2 and the flange 12 jointly seal the furnace wall 1, thereby improving the sealing performance of the furnace and helping to reduce the heat from escaping from the observation hole 11. When in use, the glass melting furnace melts the glass, and the temperature of the side of the furnace wall 1 facing the furnace cavity is higher. The other end of the flange 12 is extended outward in a direction away from the furnace wall 1 to reduce the influence of the high temperature in the furnace and reduce the size of the deformation; the groove width L22 of the groove 22 is larger than the thickness L12 of the flange 12, which is conducive to the flange 12 still being able to fit into the groove 22 under the condition of the flange 12 being deformed, thereby ensuring the sealing performance of the glass melting furnace.
