Background

In the glass production process, glass production is usually carried out using a glass kiln. In glass production, in order to improve the melting capacity of a glass melting furnace, strengthen glass liquid convection, improve glass quality and reduce the comprehensive energy consumption of the glass melting furnace, glass production enterprises generally adopt a bubbler and an electric boosting technology, and particularly in the field of high-end ultra-white glass such as ultra-thin electronic glass, high-alumina glass and the like.

When the bubbler and the electric boosting technology are adopted, a bubbling hole brick and an electric boosting electrode brick are usually arranged at the bottom of a glass melting furnace. It is known that ultra-white glass has an iron content of less than 0.015% and a very low iron content, resulting in very good heat-transmission properties. Therefore, the temperature of the bottom of the glass melting furnace is 60-100 ℃ higher than that of common glass. The temperature of the glass liquid at the bottom of the tank is high, the viscosity of the glass liquid is lower, and the permeability of the glass liquid is stronger. The risk of leakage of the glass liquid at the bubbling hole bricks and the electric boosting electrode bricks at the bottom of the pool is higher.

In addition, due to the forced convection of the bubbler and the electric boosting heating function, the glass liquid is washed and eroded in the area with the bubbling hole bricks and the electric boosting electrode bricks, so that the erosion of the area is more serious than that of other areas at the bottom of the pool.

The bottom of the tank 410 is provided with bubble hole bricks or electrically-boosted electrode bricks 420 to enhance the melting capacity of the glass melting furnace 400. The middle part of the bubbling hole brick or the electric boosting electrode brick 420 is provided with a hole 440, and the hole 440 is used for accommodating the bubbler or the electrode rod 430. The inner wall of the hole 440 has a clearance with the bubbler or the electromagnetic rod 430, that is, the bubbler or the electrode rod 430 is clearance-fitted in the hole 440, so that the bubbler or the electrode rod 430 can be replaced. Glass leakage prevention devices are arranged below the bubbling hole bricks or the electric boosting electrode bricks 420 at intervals.

And the glass leakage prevention device cools the bottom of the bubbling hole brick or the electric boosting electrode brick 420, so that on one hand, the holes 440 can be cooled uniformly and integrally. On the other hand, the temperature of the space below the bottom 410 of the glass melting furnace 400 can be obviously reduced, and the leakage of high-temperature molten glass from the holes 440 can be effectively prevented. In addition, if the high-temperature molten glass infiltrates and falls into the space below the bottom 410 of the glass melting furnace under special circumstances, the glass leakage prevention device may receive the high-temperature molten glass to prevent the high-temperature molten glass from damaging equipment in the space below the bottom 410 of the glass melting furnace 400.

As shown in fig. 1 and 2, an embodiment of the present application provides a glass leakage prevention device, which includes a body 100 and an air-cooled assembly 200 disposed on the body 100.

Wherein, the body 100 is provided with the holding tank 110, and the holding tank 110 can splendid attire coolant, and coolant can cool off the high temperature glass liquid that drops to the holding tank 110 by glass melting furnace 400. The air cooling assembly 200 is used for blowing cooling air toward the bubbling hole bricks or the electric boosting electrode bricks 420 through the slots of the accommodating groove 110 to cool the bubbling hole bricks or the electric boosting electrode bricks 420. The notch of the receiving groove 110 refers to an opening opposite to the groove bottom of the receiving groove 110.

Here, the cooling medium may be cooling liquid or solid cooling matter, and the cooling liquid may be cooling water or other cooling liquid. The solid cooling medium can be sand, etc. In some embodiments, the thickness of the cooling medium is 500mm or approximately 500mm when cooling water is used to cool the high temperature molten glass. The thickness of the cooling medium can be adjusted according to actual conditions.

Specifically, in some embodiments, the body 100 includes a bottom plate 130 and a sidewall 120. The side wall 120 encloses a groove wall forming the receiving groove 110, an end surface of the side wall 120 forms a notch of the receiving groove 110, and the bottom plate 130 forms a groove bottom of the receiving groove 110. The sidewall 120 may be formed in a cylindrical shape, a prismatic shape, a truncated cone shape, or other shapes. In some embodiments, the sidewall 120 is cylindrical, and the diameter of the cylindrical shape may be selected from 200mm to 300mm, such as 200mm, 220mm, 240mm, 250mm, 260mm, 280mm, 300mm, and the like. The side walls 120 and the bottom plate 130 may be made of stainless steel, and it should be noted that the bottom plate 130 may contact with the high-temperature molten glass, and therefore, the bottom plate 130 may be made of heat-resistant stainless steel. The bottom plate 130 and the side wall 120 may be detachably connected or fixedly connected.

In some embodiments, the bottom plate 130 is detachably connected to the side wall 120, and one side of the bottom plate 130 is rotatably connected to the bottom of the side wall 120, such as hinged thereto. The abutting portion of the bottom plate 130 and the sidewall 120 may be installed with a high temperature resistant sealing member. Correspondingly, the body is provided with a switch 150. The switch 150 can open and close the bottom plate 130 to facilitate slag discharge.

When the switch 150 is in the open position, as shown in FIG. 2, the base plate 130 may be rotated along the pivot connection to open the side wall 120. The bottom of the receiving tank 110 has an opening 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 body 100 with the opening of the bottom plate 130 for subsequent processing.

When the switch 150 is in the closed position, as shown in FIG. 1, the bottom panel 130 is closed relative to the side wall 120. For example, the switch 150 may interfere with a side of the bottom plate 130 away from the notch of the receiving groove 110 to close the bottom plate 130 against the side wall 120. For another example, the switch 150 can be locked with a side of the bottom plate 130 away from the slot of the receiving groove 110, so that the bottom plate 130 is fixedly connected with the side wall 120. Other detachable connection modes can be selected for the switch 150 and the bottom plate 130 to satisfy the requirement that the switch 150 opens and closes the bottom plate 130.

In other embodiments, the receiving groove 110 may be fixedly connected to the sidewall 120 by welding or integrally forming. The bottom of the accommodating groove 110 is provided with a slag discharge port 140. In some embodiments, the sidewall 120 is opened with the slag discharge outlet near the bottom plate 130. And a slag discharging switch is arranged at the slag discharging outlet and can be opened or closed. When the slag discharging switch opens the slag discharging outlet, the slag discharging outlet discharges the glass slag obtained by cooling by the air cooling assembly 200 or the cooling medium.

As shown in fig. 1 and 2, when the cooling medium is a cooling liquid such as cooling water, the main body is provided with a liquid inlet pipe 300, and the liquid inlet pipe 300 can inject the cooling liquid into the accommodating groove 110. In some embodiments, the side wall 120 of the main body is provided with a liquid inlet. A liquid inlet pipe 300 is installed at the liquid inlet. The distance between the liquid inlet and the bottom plate 130 may be higher than the 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 hermetically connected to the sidewall 120 of the main body.

The number of the liquid inlet pipe 300 is one or more. If a plurality of liquid inlet pipes 300 are adopted, a corresponding number of liquid inlets need to be formed 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 to the opening of the accommodating groove 110, and may also have a certain included angle, and only the cooling liquid needs to be smoothly input into the accommodating groove 110, which is not limited herein.

The liquid inlet pipe 300 is provided with a liquid regulating valve 310. The liquid regulating valve 310 can open and close the liquid inlet channel of the liquid inlet pipe 300. In addition, in some embodiments, the liquid regulating valve 310 may also control the flow rate of the cooling liquid injected into the holding tank 110 from the liquid inlet pipe 300. The liquid regulating valve 310 can keep the bottom of the holding tank 110 accumulating a certain volume of the cooling liquid, and can also reduce or stop the addition of the cooling liquid under the condition that the holding tank 110 accumulates the required volume of the cooling liquid, so as to reduce the waste of the cooling liquid.

When the cooling medium is solid cooling material such as sand, the sand can be thrown into the notch of the holding tank 110, so that the sand is laid at the bottom of the holding tank 110. A sand inlet pipe may be additionally provided to transfer the sand into the holding tank 110.

As shown in fig. 1 and 2, the air cooling assembly 200 includes an air inlet duct 210 and an air outlet duct 220. The air inlet pipe 210 is used for conveying cooling air into the main body, and the air outlet pipe 220 is used for discharging the cooling air, so that the cooling air cools the bottom of the bubbling hole brick or the electric boosting electrode brick 420.

The side wall 120 of the main body 100 is provided with an air inlet, and the air inlet is provided with the air inlet pipe 210. In some embodiments, the air inlet pipe 210 is disposed obliquely, and the air inlet pipe 210 gradually approaches the body 100 along the air inlet direction thereof. In some embodiments, the air inlet duct 210 is inclined at an angle of 30 ° to 60 °, such as 30 °, 36 °, 45 °, or 60 °, relative to the body 100.

It should be noted that the aforementioned "inclination angle of the air inlet pipe 210 relative to the body 100" refers to an included angle between a straight line of the axis of the air inlet pipe 210 and a straight line of the direction from the bottom plate 130 of the body 100 to the opening of the accommodating groove 110.

The air inlet pipe 210 is provided with an adjusting valve 230, and the adjusting valve 230 can adjust the air quantity so as to adjust the air quantity according to different conditions in the glass melting furnace 400 and meet different conditions. For example, when the temperature of the glass melting furnace 400 is low, the bottom of the bubbling hole brick or the electric boosting electrode brick 420 can be cooled by adopting a slightly small air volume; when the temperature of the glass melting furnace 400 is high, the bottom of the bubbling hole brick or the electric boosting electrode brick 420 can be cooled by adopting a slightly large air volume. The regulating valve 230 may be an air volume regulating valve. In addition, in the process of adjusting the air volume, it is also possible to observe whether the pool bottom 400 is reddish, and to appropriately increase the air volume if it is reddish, and to appropriately decrease the air volume if it is darker.

The number of the air inlet ducts 210 is at least one. In one embodiment, the number of air inlet ducts 210 can be two. In this embodiment, the air inlet pipe 210 is disposed at two sides of the body 100 facing away from each other, so that the air input into the air outlet pipe 220 is uniform.

The air outlet pipe 220 is connected to the sidewall 120 of the body 100, so that an opening on a side of the air outlet pipe 220 away from the body 100 is used as a notch of the accommodating groove 110. The air outlet pipe 220 and the sidewall 120 of the main body 100 may be integrally formed, or welded, or connected in other manners. The outlet pipe 220 is hermetically connected with the sidewall 120 of the body 100. The air outlet channel 221 in the air outlet pipe 220 is communicated with the accommodating 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 notch of the accommodating groove 110. In some embodiments, the axis of the outlet duct 220 coincides with the body centerline.

The air outlet pipe 220 has an air inlet end 223 and an air outlet end 222, and the air inlet end 223 of the air outlet pipe 220 is connected to the sidewall 120 of the body 100. The two connection modes can be welding, integral forming and other connection modes. The air outlet end 222 of the air outlet pipe 220 is a free end. During installation, a gap is formed between the end of the air outlet end 222 of the air outlet pipe 220 and the bottom surface of the bubbling hole brick or the electric boosting electrode brick 420, and the width of the gap may be 1m to 1.5m, for example, 1m, 1.2m, 1.3m, 1.4m, and 1.5 m. In addition, the central line of the air outlet pipe 220 may coincide with the central line of the bubbler or the electrode rod 430.

In some embodiments, the diameter of the air outlet pipe 220 gradually increases along the direction away from the body 100. That is, the diameter of the air outlet pipe 220 increases gradually along the direction from the air inlet end 223 to the air outlet end 222. In some embodiments, the angle between the wall of the air outlet pipe 220 and the axis of the air outlet pipe 220 may be 40 ° to 60 °, such as 40 °, 45 °, 50 °, 55 °, or 60 °. In some embodiments, the air outlet pipe 220 may be shaped like a circular truncated cone, in some other embodiments, the air outlet pipe may also be shaped like a truncated pyramid, and in other embodiments, the air outlet pipe 220 may also be shaped like a combination of a truncated pyramid and a circular truncated cone. Only need satisfy "the tuber pipe 220 along keeping away from the direction of body 100, the pipe diameter of tuber pipe 220 increases gradually" can.

The arrangement can make the air outlet pipe 220 form a horn shape, and the arrangement mode has at least the following advantages:

firstly, the diameter of the air outlet pipe 220 is gradually increased, so that the cooling area of the cooling air blown to the bottom surface of the bubbling hole brick or the electric boosting electrode brick 420 is large, and the bubbling hole brick or the electric boosting electrode brick 420 can be cooled uniformly in a large area.

Secondly, the opening of the air outlet end 222 of the air outlet pipe 220 is large, and after cooling air enters the air outlet pipe 220, the flow rate can be properly reduced, so that the phenomenon that the blowing temperature at the middle part of the air outlet pipe 220 is suddenly low due to the fact that the air quantity at the middle part of the air outlet pipe 220 is too large caused by too fast flow rate is effectively reduced, and the phenomenon that the bubbling hole brick or the electric boosting electrode brick 420 is locally overcooled and burst is caused is effectively reduced.

Third, the air outlet end 222 of the air outlet pipe 220 has a larger opening, which can receive the high-temperature glass liquid penetrating through any part of the bottom surface of the bubbling hole brick or the electric-boosting electrode brick 420, and in addition, the high-temperature glass liquid falling onto the inner wall of the air outlet pipe 220 can flow into the accommodating tank 110 along the inner wall of the air outlet pipe 220, so as to cool the cooling medium received at the bottom of the accommodating tank 110.

It should be noted here that, since the wall of the outlet pipe 220 may contact with the molten glass at high temperature, a stainless steel material with high temperature resistance may be selected when the material of the outlet pipe 220 is selected.

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 notch of the accommodating groove 110, so that the air inlet end 223 and the accommodating groove are more convenient to install. In some embodiments, the inlet end 223 of the outlet duct 220 has a port diameter of 200mm-300mm, such as 200mm, 225mm, 250mm, 280mm or 300 mm. The diameter of the outlet end 222 of the outlet duct 220 is 400mm-500mm, for example, 400mm, 425mm, 450mm, 475mm or 500 mm. 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 requirements.

The arrows in fig. 1 indicate the moving direction of the cooling air, and in conjunction with fig. 1, when the glass penetration preventing device is in operation, the cooling air is delivered through the air inlet pipe 210, and in the process, the cooling air can reach the appropriate flow rate and flow rate through the adjustment of the adjusting valve 230. The cooling air enters the accommodating 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 groove bottom to the notch of the accommodating groove 110. Subsequently, the cooling air moves from the air outlet channel 221 to the air outlet end 222, and is discharged out of the air outlet pipe 220. The cooling air is blown to the bottom of the bubbling hole brick or the electric boosting electrode brick 420 opposite to the air outlet end 222 of the air outlet pipe 220 to cool the bubbling hole brick or the electric boosting electrode brick.

Through the cooling process, the space below the whole bubbling hole brick or the electric boosting electrode brick 420 and the tank bottom 410 can be cooled, the erosion of high-temperature glass liquid to the tank bottom 410 is slowed down, and the risk of glass liquid leakage is effectively reduced. In the process of cooling the pool bottom 410 by the air cooling component, the situation of local supercooling can not be generated, and the situation that new safety problems are caused due to the fact that bricks are cracked and cracked due to the local supercooling at the pool bottom 410 and the bubbling hole bricks or the electric boosting electrode bricks 420 can be effectively reduced.

In addition, if the high-temperature molten glass leaks, the high-temperature molten glass can flow into the holding tank 110 along the inner pipe wall of the air outlet pipe 220, and forms solid low-temperature glass slag under the cooling effect of the cooling medium at the bottom of the holding tank 110. When the solid low-temperature glass slag needs to be cleaned, the switch 150 can be turned on, so that the bottom plate 130 is opened relative to the side wall 120, and the glass slag falls from the slag discharge port 140 and is discharged. The glass penetration preventing device can receive the falling high-temperature glass liquid under emergency, and the kiln bottom equipment is effectively damaged by the high-temperature glass liquid. The glass slag discharged from the slag discharge port 140 can be transported out of the glass melting furnace 400 through other receiving equipment and subjected to subsequent treatment.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the utility model. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
