Description

Technical Field

[0001] The utility model relates to the field of manufacturing overflow high-aluminum cover glass, and particularly relates to an air-cooling device for a feeding port. Background Art

[0002] The tank furnace for overflow high-aluminum cover glass is a hybrid furnace combining a natural gas oxy-fuel furnace and an electric melting furnace, with a melting temperature above 1600°C. Therefore, the temperature near the feeding port of the tank furnace is relatively high.

[0003] The bricks used for the front wall of the tank furnace of the overflow high-aluminum cover glass are CZ bricks, and the main internal component is zirconia. This kind of brick can withstand high-temperature burning at 2000°C. Although the bricks around the feeding port can withstand high temperatures, they are continuously subjected to thermal shock inside the furnace for a long time. And due to the long-term cleaning work of the feeding port, the refractory material is worn out and burned through, affecting the heat preservation effect of the melting part of the entire tank furnace; the temperature change in the upper space of the glass liquid is large, which will also frequently cause the collapse of the batch mountain, affecting the flow of the batch mountain, thus affecting the production quality. At the same time, the head of the feeder is continuously in a high-temperature environment, and some raw materials are melted in advance due to high temperature and adhere to the spiral, which will also affect the feeding efficiency of the feeder. Therefore, the tank furnace body and equipment cannot be cooled, posing a safety hazard. Content of the Utility Model
