[0017] In order to make the purpose, technical scheme and advantages of the utility model embodiment more clear, the utility model technical scheme will be described clearly and completely below in combination with the embodiment.

[0018] There are many methods to reduce and lower the bubbles in the glass liquid, and the following are the traditional common methods.

[0019] 1. Bubbling: use metal pipe or ceramic pipe to blow out the big bubbles at the bottom of the glass melting pool, and these big bubbles can take away or eliminate the small bubbles in the floating process.

[0020] 2. Stirring: adopt mechanical stirring in the glass melting process to help to eliminate the bubbles.

[0021] 3. Add clarifying agent: such as antimony trioxide, to help to eliminate the bubbles.

[0022] 4. Control the production process: reduce the generation of secondary bubbles, that is, avoid the re-precipitation of bubbles when the temperature decreases.

[0023] 5. Adjust the glass composition: reduce the viscosity of the glass melt, which helps to expel the bubbles.

[0024] 6. Extend the glass homogenization time: control the time to avoid the severe volatilization of alkaline substances in the glass melt, which leads to an increase in the viscosity of the glass.

[0025] 7. Select the appropriate state of the raw materials: for example, the particle size, too fine refractory powder is easy to produce a large number of small bubbles, and too large particle size will cause melting difficulties.

[0026] 8. Control the raw materials: avoid using raw materials containing hydrogen silicone oil to prevent the reaction with the substances in the raw materials to produce gas.

[0027] 9. Control the curing reaction of the sealant: avoid the rapid curing of the sealant, which leads to the inability to expel small molecules and the generation of bubbles.

[0028] 10. Control the temperature difference and air pressure changes: prevent external moisture from entering the glass, which leads to the generation of bubbles.

The liquid storage tank 20 is connected to a pipeline 2 1 on one side, and the pipeline 2 1 is connected to the pipeline 1 2. The defoaming mechanism 30 includes an air compressor 2 31 and a defoaming gun 32, with a pipeline 5 33 connected between the air compressor 2 31 and the defoaming gun 32. The barrel of the pipeline 5 33 penetrates through one side of the kiln, and the liquid storage tank 20 is connected to the defoaming gun 32 by a pipeline 6 36.

[0031] Specifically, the prepared defoaming liquid is stored in the inside of the storage tank 10, and the pump 1 1 is started to pump the defoaming liquid from the inside of the storage tank 10 into the inside of the liquid storage tank 20 through the pipeline 1 2 and the pipeline 2 1. The liquid storage tank 20 is provided with at least two to enable rotation and alternating use. Then the defoaming liquid is sent into the inside of the defoaming gun 32 through the pipeline 6 36, and at the same time the air compressor 2 31 injects compressed air into the defoaming gun 32, so that the defoaming liquid in the defoaming gun 32 is atomized and sprayed into the kiln to eliminate the bubbles on the glass melt, reduce the probability of retaining bubbles in the glass finished product, and ensure that the appearance and performance of the glass finished product are not affected.

[0032] As shown in Figure 2 andFigure 3 As shown, pipe 5 33 is equipped with shut-off valve 4 34 and remote control switch 1 35, and pipe 6 36 is equipped with shut-off valve 5 37 and remote control switch 2 38.

[0033] Specifically, the compressed air generated by the air compressor 31 can be controlled to be injected into the defoaming gun 32 by the shut-off valve 34 and the remote control switch 35.

[0034] like Figure 2 As shown, the liquid storage tank 20 is equipped with a pipe 28. The end of the pipe 28 away from the liquid storage tank 20 is connected to an air compressor 27. The pipe 28 is also equipped with a pressure gauge 25 and a shut-off valve 29. The pressure gauge 25 is located between the liquid storage tank 20 and the shut-off valve 29.

[0035] Specifically, the defoaming liquid inside the storage tank 20 is injected into the defoaming gun 32 by the compressed air of the air compressor 27, while the pressure gauge 25 can monitor the pressure inside the storage tank 20.

[0036] like Figure 1 and Figure 2 As shown, a level gauge 26 is installed inside the liquid storage tank 20, an exhaust device is installed on the outer wall, and a shut-off valve 22 is installed on the pipeline 21.

[0037] Specifically, the level gauge 26 can monitor the specific level of the defoaming liquid inside the storage tank 20, and the shut-off valve 22 can control whether the defoaming liquid located inside the storage tank 10 is injected into the storage tank 20.

[0038] like Figure 1 , Figure 2 and Figure 3 As shown, the exhaust component includes pipe 23, which is connected to the liquid storage tank 20 and is equipped with shut-off valve 24.

[0039] Specifically, during the process of injecting defoaming liquid into the storage tank 20, the air pressure inside the storage tank 20 will be discharged through pipe 23 to ensure the air pressure balance inside the storage tank 20.

[0040] Working principle: First, the prepared defoaming solution is stored in storage tank 10;

[0041] Close the shut-off valve 22 and shut-off valve 24 of one storage tank 20, and open the shut-off valve 22 and shut-off valve 24 of the other storage tank 20. Use pump 11 to inject defoaming liquid into the storage tank 20 with the valves open. During the injection of defoaming liquid, the air in the storage tank 20 can be vented to the outside through pipe 3 23. When the storage tank 20 is full of defoaming liquid, close the shut-off valve 22 and shut-off valve 24 of the storage tank 20, and open the shut-off valve 22 and shut-off valve 24 of the storage tank 20 that has not been filled with defoaming liquid. Fill the storage tank 20 with defoaming liquid in the same way. The two storage tanks 20 are kept in standby and can be used alternately to maintain uninterrupted use. The storage tanks are placed in a fire-free, cool, and ventilated room, away from kilns and heat sources.

[0042] High-pressure compressed air of not less than 6 Bar is injected into the liquid storage tank 20 through the pipe 28 via the air compressor 27. The defoaming liquid enters the defoaming gun 32 through the outlet pipe 36. At the same time, compressed air can be injected into the defoaming gun 32 through the air compressor 31, so that the defoaming liquid in the defoaming gun 32 is atomized and sprayed into the kiln.

[0043] When the bubbles floating on the surface of the molten glass inside the furnace are covered by the sprayed defoamer, the bubbles will burst and disappear (details of the process are provided in the appendix). Figure 2 To attach Figure 3 transition).
