Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of glass production, in particular to a glass leakage prevention device and a glass melting furnace. BACKGROUND

[0002] In the process of glass production, a glass furnace is usually used for glass production. In glass production, in order to improve the melting capacity of the glass melting furnace, strengthen the convection of the glass liquid, improve the glass quality, and reduce the comprehensive energy consumption of the glass melting furnace, glass production enterprises generally use bubblers and electric melting technology, especially in the field of high-end ultra-white glass such as ultra-thin electronic and high-aluminum glass.

[0003] When using bubblers and electric melting technology, the bubbler bricks and electric melting electrode bricks are usually placed at the bottom of the glass melting furnace. As is known to all, the iron content of ultra-white glass is less than 0.015%, which is very low, resulting in very good heat transmission performance. Therefore, the temperature of the bottom of the glass melting furnace is 60-100℃ higher than that of ordinary glass. The glass liquid at the bottom has lower viscosity and stronger permeability. The risk of glass liquid leakage at the bubbler bricks and electric melting electrode bricks at the bottom is greater.

[0004] In addition, due to the forced convection of the bubbler and the heating effect of the electric melting, the glass liquid is eroded in the area with the bubbler bricks and the electric melting electrode bricks, and the erosion in this area is more serious than that in other areas of the bottom.

[0005] Therefore, there is an urgent need for a glass leakage prevention device that can effectively prevent glass liquid from leaking from the area with the bubbler bricks and the electric melting electrode bricks. SUMMARY

[0033] As shown in Figure 1 An embodiment of the present application provides a glass melting furnace 400 with a pool bottom 410. The pool bottom 410 is provided with a bubbling hole brick or an electric melting electrode brick 420 to improve the melting capacity of the glass melting furnace 400. A hole 440 is formed in the middle of the bubbling hole brick or the electric melting electrode brick 420, and the hole 440 is used to accommodate a bubbler or an electrode rod 430. The inner wall of the hole 440 has a gap with the bubbler or the electrode rod 430, that is, the bubbler or the electrode rod 430 is fitted in the hole 440 in a clearance fit, so as to facilitate replacement of the bubbler or the electrode rod 430. A glass leakage prevention device is arranged below the bubbling hole brick or the electric melting electrode brick 420. The glass leakage prevention device can cool the bottom of the bubbling hole brick or the electric melting electrode brick 420, and also can receive the falling glass liquid. It should be noted that the "falling glass liquid" includes the glass liquid penetrated from the hole 440, and also includes the high-temperature glass liquid leaked from other parts of the bubbling hole brick or the electric melting electrode brick 420.

[0034] During the glass making process, the high-temperature glass liquid is easy to leak from the bubbling hole brick or the electric melting electrode brick 420 to the space below the pool bottom 410 of the glass melting furnace 400. The glass leakage prevention device cools the bottom of the bubbling hole brick or the electric melting electrode brick 420, which can uniformly cool the hole 440 as a whole, and also can significantly reduce the temperature of the space below the pool bottom 410 of the glass melting furnace 400, so as to effectively prevent the high-temperature glass liquid from leaking from the hole 440. In addition, if the high-temperature glass liquid penetrates and falls to the space below the pool bottom 410 under special circumstances, the glass leakage prevention device can receive the high-temperature glass liquid, so as to prevent the high-temperature glass liquid from damaging the equipment in the space below the pool bottom 410 of the glass melting furnace 400.

[0035] As shown in Figure 1 As shown in Figure 2 An embodiment of the present application provides a glass leakage prevention device, which comprises a body 100 and an air cooling assembly 200 arranged on the body 100.

[0036] The main body 100 is provided with a receiving tank 110, which can hold a cooling medium to cool the high-temperature molten glass falling from the glass melting furnace 400 into the receiving tank 110. The air cooling assembly 200 is used to blow cooling air through the notch of the receiving tank 110 toward the bubbling hole bricks or electric fluxing electrode bricks 420 to cool the bubbling hole bricks or electric fluxing electrode bricks 420. The notch of the receiving tank 110 refers to the opening opposite the bottom of the receiving tank 110.

[0037] It should be noted that the cooling medium can be a coolant or a solid coolant. The coolant can be cooling water or other cooling liquids. The solid cooling medium can be sand, gravel, sand, or other materials. In some embodiments, when cooling water is used, the thickness of the cooling medium is 500 mm or approximately 500 mm to cool the high-temperature molten glass. The thickness of the cooling medium can also be adjusted according to actual conditions.

[0038] Specifically, in some embodiments, the body 100 includes a bottom plate 130 and a side wall 120. The side wall 120 is arranged to form the groove wall of the accommodating groove 110, the end face of the side wall 120 forms the notch of the accommodating groove 110, and the bottom plate 130 forms the groove bottom of the accommodating groove 110. Among them, the side wall 120 can be arranged to form a cylindrical, prismatic, truncated cone or other shapes. In some embodiments, the side wall 120 is arranged to be cylindrical, and the diameter of the cylinder can be selected from 200mm-300mm, for example, it can be 200mm, 220mm, 240mm, 250mm, 260mm, 280mm and 300mm. The material of the side wall 120 and the bottom plate 130 can be stainless steel. It should be noted here that since the bottom plate 130 may come into contact with high-temperature glass liquid, heat-resistant stainless steel can be preferably selected in the material selection of the bottom plate 130. The bottom plate 130 and the side wall 120 may be detachably connected or fixedly connected.

[0039] In some embodiments, the bottom plate 130 and the side wall 120 are detachably connected, and one side of the bottom plate 130 is pivotally connected to the bottom of the side wall 120, for example, by a hinged connection. A high-temperature-resistant seal may be installed at the point where the bottom plate 130 and the side wall 120 meet. Correspondingly, the main body is provided with a switch 150. This switch 150 can be used to open and close the bottom plate 130 to facilitate slag discharge.

[0040] When the switch 150 is in the open position, Figure 2 As shown, the bottom plate 130 can be rotated along the rotating connection to open relative to the side wall 120. The bottom of the receiving tank 110 now has an opening, which serves as a slag discharge port 140. The glass slag obtained by cooling with the air cooling assembly 200 or the cooling medium can fall out of the main body 100 as the bottom plate 130 opens, facilitating subsequent processing.

[0041] When the switch 150 is in the closed position, as shown in Figure 1 the bottom plate 130 is closed relative to the side wall 120. For example, the switch 150 can be in contact with the side of the bottom plate 130 away from the slot of the containing groove 110 to close the bottom plate 130 relative to the side wall 120. For another example, the switch 150 can be locked with the side of the bottom plate 130 away from the slot of the containing groove 110 so that the bottom plate 130 is fixedly connected with the side wall 120. The switch 150 and the bottom plate 130 can also be detachably connected in other ways to meet the opening and closing of the bottom plate 130 by the switch 150.

[0042] In some other embodiments, the containing groove 110 can be fixedly connected with the side wall 120, such as by welding or one-piece forming. The bottom of the containing groove 110 is provided with a slag discharge port 140. In some embodiments, the side wall 120 is provided with the slag discharge port near the bottom plate 130. The slag discharge port is provided with a slag discharge switch which can open or close the slag discharge port. When the slag discharge switch opens the slag discharge port, the slag discharge port discharges the glass slag obtained by air cooling or cooling medium cooling.

[0043] As shown in Figure 1 and Figure 2 When the cooling medium is cooling liquid such as cooling water, the main body is provided with a liquid inlet pipe 300 which can inject the cooling liquid into the containing groove 110. In some embodiments, the side wall 120 of the main body is provided with a liquid inlet port. The liquid inlet pipe 300 is installed at the liquid inlet port. The distance between the liquid inlet port and the bottom plate 130 can be higher than the required height of the cooling liquid so as to reduce the resistance when the liquid inlet pipe 300 delivers the cooling liquid. The liquid inlet pipe 300 is sealingly connected with the side wall 120 of the main body.

[0044] The number of liquid inlet pipes 300 is one or more. If multiple liquid inlet pipes 300 are used, a corresponding number of liquid inlet ports can be provided on the side wall 120. In some embodiments, the axial direction of the liquid inlet pipe 300 is perpendicular to the direction from the bottom of the containing groove 110 to the opening, or can have a certain angle, as long as the cooling liquid can be smoothly input into the containing groove 110, which is not limited herein.

[0045] The liquid inlet pipe 300 is provided with a liquid regulating valve 310. The liquid regulating valve 310 can open or close the liquid inlet channel of the liquid inlet pipe 300. In addition, in some embodiments, the liquid regulating valve 310 can also control the flow rate of the cooling liquid injected into the containing groove 110 by the liquid inlet pipe 300. The liquid regulating valve 310 can keep a certain volume of cooling liquid accumulated at the bottom of the containing groove 110, or can reduce or stop the addition of cooling liquid when the containing groove 110 accumulates the required volume of cooling liquid, so as to reduce the waste of cooling liquid.

[0046] When the cooling medium is selected as a solid cooling material such as sand, the sand can be poured into the opening of the containing groove 110 so as to be laid on the groove bottom of the containing groove 110. A sand feeding pipe can also be additionally provided so as to deliver the sand into the containing groove 110.

[0047] As shown in Figure 1 With Figure 2 As shown in the drawings, the air cooling assembly 200 comprises an air inlet pipe 210 and an air outlet pipe 220. The air inlet pipe 210 is used to deliver cooling air into the main body, and the air outlet pipe 220 is used to exhaust the cooling air so as to cool the bottom of the bubble brick or the electrode brick 420.

[0048] The sidewall 120 of the main body 100 is provided with an air inlet opening, and the air inlet pipe 210 is installed at the air inlet opening. In some embodiments, the air inlet pipe 210 is obliquely arranged, and the air inlet pipe 210 gradually approaches the main body 100 along the air inlet direction thereof. In some embodiments, the air inlet pipe 210 is obliquely arranged at an angle of 30°-60° with respect to the main body 100, such as 30°, 36°, 45° or 60°, etc.

[0049] It should be noted that the "inclination angle of the air inlet pipe 210 with respect to the main body 100" refers to the angle between the straight line where the axis of the air inlet pipe 210 is located and the straight line where the direction from the bottom plate 130 of the main body 100 to the opening of the containing groove 110 is located.

[0050] The air inlet pipe 210 is provided with an adjusting valve 230, which can adjust the air volume so as to adjust the air volume according to different conditions in the glass melting furnace 400 to meet different conditions. For example, when the temperature of the glass melting furnace 400 is relatively low, a slightly smaller air volume can be used to cool the bottom of the bubble brick or the electrode brick 420; when the temperature of the glass melting furnace 400 is relatively high, a slightly larger air volume can be used to cool the bottom of the bubble brick or the electrode brick 420. The adjusting valve 230 can be selected as an air volume adjusting valve. In addition, during the adjustment of the air volume, the redness of the pool bottom 400 can also be observed, and if the pool bottom 400 is relatively red, the air volume can be appropriately increased, and if the pool bottom 400 is relatively dark, the air volume can be appropriately reduced.

[0051] The number of the air inlet pipe 210 is at least one. In an embodiment, the number of the air inlet pipe 210 can be two. In this embodiment, the air inlet pipe 210 is arranged on the two opposite sides of the main body 100 so as to make the air input into the air outlet pipe 220 more uniform.

[0052] The air outlet pipe 220 is connected with the sidewall 120 of the body 100, so that the air outlet pipe 220 is open to the side of the body 100 as a slot of the containing groove 110. The air outlet pipe 220 and the sidewall 120 of the body 100 can be integrally formed, welded, or connected in other ways. The air outlet pipe 220 is sealingly connected with the sidewall 120 of the body 100. The air outlet channel 221 in the air outlet pipe 220 is in communication with the containing groove 110. In addition, the air outlet direction of the air outlet pipe 220 is consistent with the direction from the bottom plate 130 to the slot of the containing groove 110. In some embodiments, the axis of the air outlet pipe 220 coincides with the center line of the main body.

[0053] The air outlet pipe 220 has an air inlet end 223 and an air outlet end 222. The air inlet end 223 of the air outlet pipe 220 is connected with the sidewall 120 of the body 100. The connection mode can be welding, integrally formed, or other connection modes. The air outlet end 222 of the air outlet pipe 220 is a free end. During installation, the end of the air outlet end 222 of the air outlet pipe 220 has a gap between the bottom surface of the bubble hole brick or the electrically assisted melting electrode brick 420, and the width of the gap can be 1m-1.5m, such as 1m, 1.2m, 1.3m, 1.4m, 1.5m. In addition, the center line of the air outlet pipe 220 can coincide with the center line of the bubble generator or the electrode rod 430.

[0054] In some embodiments, the diameter of the air outlet pipe 220 gradually increases in the direction away from the body 100. That is, the diameter of the air outlet pipe 220 gradually increases in the direction from the air inlet end 223 to the air outlet end 222 of the air outlet pipe 220. In some embodiments, the angle between the wall of the air outlet pipe 220 and the axis of the air outlet pipe 220 can be 40°-60°, such as 40°, 45°, 50°, 55°, or 60°, etc. In some embodiments, the air outlet pipe 220 can be a frustum-like shape, in some other embodiments, the air outlet pipe can also be a prismatic frustum-like shape, and in some other embodiments, the air outlet pipe 220 can also be a combination of prismatic frustum and frustum. Only the condition that “the diameter of the air outlet pipe 220 gradually increases in the direction away from the body 100” needs to be met.

[0055] The above arrangement can make the air outlet pipe 220 form a horn-like shape, and this arrangement has at least the following advantages:

[0056] Firstly, the gradually increasing diameter of the air outlet pipe 220 can make the cooling area of the cooling air blowing on the bottom surface of the bubble hole brick or the electrically assisted melting electrode brick 420 larger, so that the bubble hole brick or the electrically assisted melting electrode brick 420 can be cooled more uniformly and in a larger area.

[0057] Secondly, the opening of the air outlet end 222 of the air outlet pipe 220 is large, so that the flow rate of the cooling air can be appropriately reduced after entering the air outlet pipe 220, effectively reducing the excessive air flow in the middle of the air outlet pipe 220 due to the excessive flow rate, thereby effectively reducing the situation that the bubble hole brick or the electric smelting electrode brick 420 is locally supercooled and explodes.

[0058] Thirdly, the opening of the air outlet end 222 of the air outlet pipe 220 is large, which can accommodate the high-temperature glass liquid permeated from any part of the bottom surface of the bubble hole brick or the electric smelting electrode brick 420, and in addition, the high-temperature glass liquid falling on the inner wall of the air outlet pipe 220 can flow along the inner wall of the air outlet pipe 220 to the containing groove 110, so as to cool the cooling medium contained in the bottom of the containing groove 110.

[0059] It should be noted here that since the pipe wall of the air outlet pipe 220 can be in contact with the high-temperature glass liquid, when selecting the material of the air outlet pipe 220, a high-temperature stainless steel material can be selected.

[0060] The size of the port of the air inlet end 223 of the air outlet pipe 220 can be the same as the size of the slot of the containing groove 110, so as to facilitate the installation of the two. In some embodiments, the diameter of the port of the air inlet end 223 of the air outlet pipe 220 is 200-300 mm, such as 200 mm, 225 mm, 250 mm, 280 mm, or 300 mm, etc. The diameter of the port of the air outlet end 222 of the air outlet pipe 220 is 400-500 mm, such as 400 mm, 425 mm, 450 mm, 475 mm, or 500 mm, etc. The distance between the air inlet end 223 and the air outlet end 222 of the air outlet pipe 220 can be adjusted according to actual needs.

[0061] Figure 1 The arrows in the figure represent the moving direction of the cooling air, and the figure combines the above-mentioned figures. Figure 1 When the anti-glass permeation device is working, the cooling air is transported by the air inlet pipe 210, and in this process, by adjusting the adjusting valve 230, the cooling air can reach a suitable flow rate and flow. The cooling air enters the containing groove 110 from the air inlet pipe 210, and moves to the air inlet end 223 of the air outlet pipe 220 along the direction from the bottom to the slot of the containing groove 110. Then, the cooling air moves to the air outlet end 222 of the air outlet pipe 220 through the air outlet channel 221, and is discharged from the air outlet pipe 220. The cooling air blows to the bottom of the bubble hole brick or the electric smelting electrode brick 420 opposite to the air outlet end 222 of the air outlet pipe 220, so as to cool the bubble hole brick or the electric smelting electrode brick 420.

[0062] Through the above cooling process, the whole bubble hole brick or electric melting electrode brick 420 and the space below the pool bottom 410 can be cooled, the erosion of the high-temperature glass liquid to the pool bottom 410 is slowed down, and the risk of glass liquid leakage is effectively reduced. During the cooling process of the air cooling assembly to the pool bottom 410, there is no local supercooling, effectively reducing the risk of brick explosion caused by local supercooling of the pool bottom 410 and the bubble hole brick or electric melting electrode brick 420, and causing new safety problems.

[0063] In addition, if high-temperature glass liquid seepage leakage occurs, the high-temperature glass liquid can flow along the inner pipe wall of the air outlet pipe 220 into the containing groove 110, and under the cooling effect of the cooling medium at the bottom of the containing groove 110, solid low-temperature glass slag is formed. When it is necessary to clean the solid low-temperature glass slag, the switch 150 can be opened, so that the bottom plate 130 is opened relative to the side wall 120, so that the glass slag falls and is discharged from the slag discharge port 140. The anti-glass seepage device can catch the falling high-temperature glass liquid in an emergency, effectively preventing the high-temperature glass liquid from damaging the kiln bottom equipment. The glass slag discharged from the slag discharge port 140 can be transported out of the glass melting furnace 400 by other receiving equipment and subjected to subsequent treatment.

[0064] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described, but as long as the combinations of the technical features do not contradict each other, they should be considered within the scope of the present disclosure.

[0065] The above-described embodiments only express several embodiments of the present application, and the description is more specific and detailed, but it should not be understood as limiting the scope of the patent. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are within the scope of the present application. Therefore, the scope of protection of the present application should be subject to the appended claims.
