Description

Technical Field

[0001] The utility model relates to the technical field of glass kilns, in particular to a sealing structure for a feeding port of a large glass kiln during kiln baking. Background Art

[0002] During the glass kiln baking process, a baking gun is installed at the feed port. The temperature gradually rises over 10-15 days, reaching a "high-fire" temperature of around 1000°C. The in-house combustion system then switches on, and at around 1350°C, air delivery of cullet begins. Once the glass reaches the desired liquid level, the baking gun is removed and the feeder is pushed in. The entire process, from the start of the kiln baking process to the introduction of the feeder, typically takes 15 to 30 days. The kiln temperature rises from room temperature to around 1500°C. During this period, the feed port must remain sealed. Due to the large temperature fluctuations and numerous operations, the structure used must be resistant to high temperatures and thermal shock. After the kiln baking is complete, the sealing device for the feed port must be easily removed while still hot.

[0003] At present, during the kiln baking period, the feeding port is generally sealed with water bars and clay cover bricks. The supporting strength of the sealing structure is low and it is inconvenient to install and disassemble, which affects the installation efficiency of the feeding port sealing structure.
