Description

Technical Field

[0001] The utility model relates to the technical field of glass melting, in particular to a microcrystalline glass melting furnace. Background Art

[0002] Glass melting is one of the important processes in glass production. It is a process in which the batch materials are heated at high temperature to form a uniform, bubble-free glass liquid that meets the forming requirements. The melting process is divided into five stages: silicate formation, glass formation, clarification, homogenization and cooling. When melting the glass, it is usually poured into a melting furnace to melt it into glass liquid. During melting, due to the different temperatures above and below the melting furnace, the temperature at the bottom of the melting furnace may be higher than the temperature at the top or side, resulting in uneven heating of the glass melting.

[0003] A search was conducted to find out the above-mentioned problems. In the prior art that has been disclosed, for example, an optical glass melting device proposed in publication number CN215667697U installs a stirring shaft and stirring blades in a melting furnace, and rotates the stirring shaft through gear meshing, so that the stirring blades stir the glass in the melting furnace to rotate and heat the glass. However, during stirring, the glass in the melting furnace can be flipped horizontally, but it may be difficult to flip the glass vertically. Since the upper glass squeezes the bottom glass, it is difficult to flip the bottom glass up and transport the upper glass down, which may still cause uneven heating of the glass.
