Description

Automatic reinforced glass smelting pot

Technical Field

The invention relates to the field of glass processing smelting furnace equipment, in particular to an automatic charging glass smelting furnace.

Background

In a glass product factory, quartz sand and recycled glass are required to be mixed according to a certain proportion, added into a smelting furnace and gradually output to a glass product production line in a molten state. Nowadays, large-scale factories rarely adopt a manual feeding production mode, and most of the large-scale factories adopt automatic conveying equipment to input glass materials into a glass melting furnace.

Glass melting furnaces are often large, and in order to avoid excessive liquid surface temperatures, glass frits are generally used to cover molten glass, i.e., red tops in glass melting furnaces are avoided in factories. As the new glass frit on the inner surface of the glass melting furnace is heated to be continuously melted and finally becomes molten glass melt, the red top phenomenon occurs again, so that the new glass frit needs to be continuously added to the surface of the glass melt in the glass melting furnace.

In the existing equipment, a conveyor belt is usually extended into a glass melting furnace, and glass frits are uniformly added to the surface of a glass melt through the extension and contraction and the swing of the conveyor belt. However, the conveyor belt stays in the high-temperature glass melting furnace for a long time, so that the service life of the conveyor belt is short, the conveyor belt needs to be replaced frequently, the production cost is high, and the production efficiency is influenced.
