Description

Technical Field

[0001] The utility model relates to the field of glass manufacturing, and more specifically, to a glass kiln bubbling device and a glass kiln. Background Art

[0002] In the glass manufacturing process, the bubbling process is often used to treat the molten glass. That is, gas at a certain pressure is injected into the bottom of the molten glass so that the bubbles drive the flow of the molten glass and absorb small bubbles, which helps to improve the melting efficiency of the glass and enhance the clarification effect of the molten glass.

[0003] Since the temperature in the glass furnace is too high, especially the position in contact with the molten glass needs to withstand a high temperature of about 1200 degrees Celsius, resulting in a short service life and frequent maintenance. In order to solve the above problems, the glass furnace bubbling device of the prior art, as shown in the utility model patent with publication number CN219861037U, can move the height of the bubbler to facilitate maintenance and replacement, and can also extract the molten glass when bubbling is not needed to avoid being in high temperature for a long time.

[0004] However, most of the bubbler's air tube is still immersed in the glass melt, which will have a great impact on its service life. It needs to be frequently lifted up for maintenance or cooling. If the process requires long-term bubbling, it will not help its service life at all.

[0005] Therefore, there is an urgent need for a novel glass furnace bubbling device that can solve the above problems. Utility Model Content

[0006] One purpose of the utility model is to solve the problem that the existing glass furnace bubbling device is immersed in glass melt, resulting in a short service life.

[0007] According to one aspect of the utility model, a glass kiln bubbling device is provided, comprising an air pipe and a bubbler, wherein the bubbler is connected to the air pipe, the air pipe is arranged below the glass kiln, a plurality of branch pipes are arranged on the air pipe, the branch pipes are connected to the bubbler, and the air pipe and the branch pipes are wrapped with a heat insulation device; the bubbler comprises a ceramic sleeve, the ceramic sleeve is arranged outside the branch pipe, and a plurality of bubbling holes are arranged on the ceramic sleeve.

[0008] Through this solution, the ceramic sleeve can withstand the high temperature in the kiln, and the branch pipe and the air pipe will not directly extend into the glass melt in the kiln for bubbling, which plays a protective role for the branch pipe. In addition, the heat insulation device wrapped around the air pipe and the branch pipe can further improve the protection effect, increase the service life of the air pipe, and reduce the maintenance frequency.

[0009] Preferably, the heat insulation device is a ceramic tube, the ceramic tube sleeve is arranged outside the air pipe, a plurality of connecting holes are opened on the ceramic tube, and the branch pipe extends into the bubbler through the connecting holes.

[0010] Through this solution, the ceramic has good high temperature resistance and can provide good protection for the trachea.

[0011] Preferably, a cold water pipe is provided outside the trachea sleeve, the inner diameter of the cold water pipe is larger than the outer diameter of the trachea, a return water pipe is provided inside the ceramic tube, the return water pipe is connected with the cold water pipe to form a loop; the branch pipe is arranged through the outer wall of the cold water pipe.

[0012] Through this solution, the cold water pipe can further take away the heat around the air pipe and branch pipe to adapt to the high temperature at the bottom of the kiln; hot air can also be introduced into the cold water pipe as needed to maintain the temperature of the gas in the air pipe to meet the process requirements.

[0013] Preferably, the bubbler further comprises a protective cap, which is disposed outside the ceramic sleeve and is slidably connected to the ceramic sleeve and can expose the bubbling hole under the action of air pressure.

[0014] Through this solution, the protective cap is made of high-temperature resistant materials such as ceramics. When bubbling is not needed, the protective cap can cover the bubbling hole to prevent the glass melt from passing through the bubbling hole and causing blockage, or entering the branch pipe and causing damage to the branch pipe.

[0015] Preferably, the bubbling hole is arranged on the side of the ceramic sleeve, the top of the ceramic sleeve is open, and the protective cap can cover the bubbling hole.

[0016] Through this solution, if bubbling is required, high-pressure air is introduced into the air pipe, and the high-pressure air can push the protective cap upward, thereby exposing the bubbling hole for bubbling operation; when the air pipe is closed, the protective cap will drop under the pressure of the top glass melt and be put back on the ceramic sleeve to cover the bubbling hole.

[0017] Preferably, the top of the protective cap is a spherical surface.

[0018] According to this embodiment, the resistance during the flow of molten glass can be reduced.

[0019] According to a second aspect of the present application, a glass kiln is provided, which adopts the above-mentioned glass kiln bubbling device.

[0020] One technical effect of the utility model is that, by adopting the glass kiln bubbling device, the air pipe is isolated from the glass melt while ensuring the bubbling effect, and the bubbling hole can be protected from blockage, which not only helps to increase the service life of the air pipe, but also reduces the maintenance frequency, and helps to improve the production efficiency of glass.

[0032] Techniques and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the techniques and equipment should be considered part of the specification.

[0033] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0034] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0035] like Figures 1 to 7 As shown, a glass kiln bubbling device in an embodiment of the present application includes an air pipe 100 and a bubbler 200. The bubbler 200 is connected to the air pipe 100. The air pipe 100 is arranged below the glass kiln. A plurality of branch pipes 110 are provided on the air pipe 100. The branch pipes 110 are connected to the bubbler 200. The air pipe 100 and the branch pipes 110 are wrapped with a heat insulation device. The bubbler 200 includes a ceramic sleeve 210. The ceramic sleeve 210 is arranged outside the branch pipe 110. A plurality of bubbling holes 211 are provided on the ceramic sleeve 210.

[0036] Through the scheme of this embodiment, the ceramic sleeve 210 can withstand the high temperature in the kiln, and the branch pipe 110 and the air pipe 100 will not directly extend into the glass melt in the kiln for bubbling, which plays a protective role for the branch pipe 110. In addition, the air pipe 100 and the heat insulation device wrapped around the branch pipe 110 can further improve the protection effect, increase the service life of the air pipe 100, and reduce the maintenance frequency.

[0037] The ceramic sleeve 210 in this embodiment is made of high temperature resistant materials such as ceramics, corundum, clay, etc., and can also be carved from fireproof bricks, which is consistent with the material of the glass kiln to ensure the heat insulation and heat resistance effect.

[0038] In one embodiment of the present application, the heat insulating device is a ceramic tube 120, which is set outside the air pipe 100. The ceramic tube 120 is provided with a plurality of connection holes, and the branch pipe 110 extends into the bubbler 200 through the connection holes. Ceramics have good high temperature resistance and can provide good protection for the air pipe 100.

[0039] In one embodiment of the present application, a cold water pipe 130 is disposed outside the air pipe 100, the inner diameter of the cold water pipe 130 is larger than the outer diameter of the air pipe 100, a return water pipe 131 is disposed inside the ceramic tube 120, and the return water pipe 131 is connected with the cold water pipe 130 to form a loop; the branch pipe 110 is arranged through the outer wall of the cold water pipe 130. The cold water pipe 130 can further take away the heat around the air pipe 100 and the branch pipe 110 to adapt to the high temperature at the bottom of the kiln; hot air can also be introduced into the cold water pipe 130 as needed to maintain the temperature of the gas in the air pipe 100 to meet the process requirements.

[0040] The ceramic sleeve 210 is connected to the outside of the ceramic tube 120 through threads. Its material is consistent with that of the ceramic tube. The connection is firm and easy to replace. It can also be directly plugged into the ceramic tube 120 through a mortise and tenon structure.

[0041] In one embodiment of the present application, the bubbler 200 further includes a protective cap 220, which is disposed outside the ceramic sleeve 210 and is slidably connected to the ceramic sleeve 210 and can expose the bubbling hole 211 under the action of gas pressure. The protective cap 220 is made of high temperature resistant material such as ceramics. When bubbling is not required, the protective cap 220 can cover the bubbling hole 211 to prevent the glass melt from passing through the bubbling hole 211 and causing blockage, or entering the branch pipe 110 and causing damage to the branch pipe 110.

[0042] In one embodiment of the present application, the bubbling hole 211 is arranged on the side of the ceramic sleeve 210, the top of the ceramic sleeve 210 is open, and the protective cap 220 can cover the bubbling hole 211. If bubbling is required, high-pressure air is introduced into the air pipe 100, and the high-pressure air can push the protective cap 220 upward, thereby exposing the bubbling hole 211 for bubbling operation; when the air pipe 100 is closed, the protective cap 220 will be squeezed by the top glass melt and fall back on the ceramic sleeve 210 to cover the bubbling hole 211.

[0043] In one embodiment of the present application, the top of the protective cap 220 is a spherical surface, which can reduce the resistance of the glass melt during its flow. The material of the protective cap 220 is consistent with that of the ceramic tube 120, and the surface is smooth, which not only reduces the friction between the protective cap 220 and the glass melt, but also reduces the friction between the protective cap 220 and the ceramic tube 120, facilitating smooth movement between them.

[0044] The glass furnace in one embodiment of the present application adopts the above-mentioned glass furnace bubbling device.

[0045] One technical effect of this embodiment is that, by using the glass kiln bubbling device, the air pipe is isolated from the glass melt while ensuring the bubbling effect, and the bubbling hole can be protected from blockage, which not only helps to increase the service life of the air pipe, but also reduces the maintenance frequency, and helps to improve the production efficiency of glass.

[0046] Although some specific embodiments of the present invention have been described in detail by way of examples, it should be understood by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the present invention. It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present invention.
