Description

Technical Field

[0001] The utility model relates to the technical field of glass fiber kiln pool wall cooling devices, in particular to a glass fiber kiln pool wall cooling device. Background Art

[0002] The liquid level line of the fiberglass kiln pool wall tiles is at the gas-solid-liquid three-phase interface and is subjected to direct erosion of the pile and glass liquid at high temperatures. The operating environment is very harsh, so this part is most severely eroded. The erosion rate of the liquid level line directly affects the overall life of the kiln. Therefore, how to effectively extend the service life of the pool wall tiles is very important in the production process of fiberglass kilns.

[0003] The erosion rate of kiln pool wall bricks increases significantly with the increase of temperature. After the interface temperature of glass refractory material reaches 1350℃, the erosion rate will almost double with every 50℃ increase. Therefore, controlling the temperature of kiln pool wall is the most direct and effective way to extend the service life of pool wall bricks. However, the installation process of kiln pool wall cooling air duct is relatively random, and the positioning basically depends on the experience of the installer. The cooling effect varies. Therefore, a unified, stable, continuous, efficient and controllable glass fiber kiln pool wall cooling device is needed to ensure the controllable cooling effect. Utility Model Content
