[0018] Embodiment

[0019] As Figs. 1 to 3As shown, in the embodiment, a glass bubbling device is mainly disclosed, which has simple structure and is easy to maintain, and can effectively reduce the failure rate of the bubbling device, and the structure comprises a gas pipe 1, a bubbling hole 10 is formed in the lower side wall of the gas pipe 1, a piston 2 for opening or closing the bubbling hole 10 is movably connected in the gas pipe 1, a top rod 3 extending out of the lower part of the gas pipe 1 is arranged below the piston 2, and an upper protrusion 11 and a lower protrusion 12 for limiting the movement of the piston 2 are arranged on the inner wall of the gas pipe 1 at both ends of the piston 2. Specifically, the piston 2 and the top rod 3 are connected to form an integral body, and in the natural state, the piston 2 is limited by abutting against the lower protrusion 12 under the action of gravity, at this time, the gas pipe 1 is not communicated with the bubbling hole 10; the bubbling device is moved downward, and the lower part thereof is inserted into the glass liquid, the piston 2 is pushed upward by the abutting action of the top rod 3 at the bottom of the kiln, so that the gas pipe 1 and the bubbling hole 10 are communicated, and the glass liquid is bubbled. When the bubbling is not needed for a long time, the bubbling device can be lifted upward and separated from the glass liquid, and the piston 2 returns to the closed state under the action of gravity. The opening or closing of the bubbling hole 10 is controlled by the up-down movement of the piston 2, and the precise control of the bubbling process is realized. The movement range of the piston 2 is limited by the upper protrusion 11 and the lower protrusion 12, and the stability and reliability of the bubbling operation are ensured.

[0020] Further, in specific implementation, the above-mentioned bubbling hole 10 is inclined downward in the embodiment of the utility model. On the one hand, the gas is introduced by being inclined downward, so that the low-temperature glass liquid at the bottom of the glass kiln is brought to the liquid surface, the heat exchange with the flame space is promoted, the glass liquid at the bottom is fully stirred, and the homogenization effect and melting efficiency of the glass liquid are improved. On the other hand, when the bubbling device is lifted upward, the glass liquid in the bubbling hole 10 can naturally fall under the action of gravity, avoiding being retained in the bubbling hole 10 and causing the bubbling hole 10 to be blocked.

[0021] Further, in specific implementation, the above-mentioned gas pipe 1 is sleeved with a protection pipe 4, and the protection pipe 4 and the gas pipe 1 are circulated with cooling medium through the inlet pipe 41 and the outlet pipe 42. Specifically, the cooling medium can adopt cooling water. Through the inlet pipe 41 and the outlet pipe 42, the circulation cooling is realized, the bubbling device is continuously cooled, the damage of high temperature to the bubbling device is reduced, the service life of the device is prolonged, and the maintenance frequency is reduced.

[0022] Preferably, the protection pipe 4, the piston 2 and the top rod 3 are all made of ceramic material. They have excellent high-temperature resistance, corrosion resistance and wear resistance, can work stably in high-temperature glass liquid for a long time, and reduce the failure and maintenance frequency caused by high-temperature environment.

[0023] Further, in the specific implementation, the vertical hole 21 is arranged on the top of the piston 2, and the branch hole 22 for matching the bubble hole 10 is arranged on the side wall of the piston 2 and communicated with the vertical hole 21. Specifically, the piston 2 is tightly attached to the inner wall of the air pipe 1, so that the side wall of the piston 2 can effectively block the bubble hole 10.

[0024] Further, in the specific implementation, the bubble hole 10 is evenly arranged along the circumferential direction of the air pipe 1. Specifically, the branch hole 22 of the piston 2 corresponds to the bubble hole 10. The bubbles can form uniform air flow in the glass liquid, promote the flow and homogenization of the glass liquid. This design can also avoid overheating or overcooling in the local area, and improve the overall quality of the glass melting.

[0025] Further, in the specific implementation, the sealing ring 31 is arranged on the top rod 3 and in contact with the inner wall of the air pipe 1. Specifically, the sealing ring 31 can be made of ceramic material and integrated with the top rod 3 to prevent the glass liquid from entering the inside of the air pipe 1.

[0026] In the embodiment, a glass kiln is also disclosed, which comprises a kiln body 5. The air pipe 1 is movably inserted into the kiln body 5 through the flange 51 arranged on the top of the kiln body 5, and the top rod 3 is in abutment with the inner bottom of the kiln body 5. Specifically, the bubble device is placed on the kiln body 5 under the action of its own gravity, and can push the piston 2 to abut against the upper protrusion 11 to continuously blow air. If long-time air supply is needed, the bubble device can be bolted with the flange 51 arranged on the top of the kiln body 5. When air blowing is not needed, the bubble device can be lifted by the lifting device and suspended above the glass liquid. When maintenance is needed, the bubble device can be pulled out by the lifting device, and the cover is connected to the flange 51.
