Description

Technical Field

[0001] The utility model relates to the technical field of glass crucible furnaces, in particular to a heat storage type glass crucible furnace. Background Art

[0002] The main process of glass production today is high-temperature hot melting. This process uses high temperature to melt and clarify the glass raw materials into glass liquid that meets the molding requirements, and then goes through a molding and cooling process to make a finished glass product. The furnaces that currently achieve high-temperature hot melting of glass mainly include crucible furnaces and pool furnaces. Compared with pool furnaces, crucible furnaces have simple structures, low costs, fast construction, and are suitable for rapid production. They have strong adaptability to processes, can change materials at any time, and can melt several glasses with similar properties and melting systems in different crucibles at the same time.

[0003] When the existing glass crucible furnace is hot-melting the glass, a stirring device is generally used to accelerate the efficiency of the glass hot-melting and make the hot-melting more uniform. However, when the glass hot-melt is stirred, the molten glass will form many small bubbles. When there are too many small bubbles and the distance between them is close, large bubbles are easily formed. As the stirring work proceeds, the bursting of large bubbles will cause the solution to splash, which is not conducive to the complete formation of the solution, and is not conducive to the subsequent removal of the solution.

[0004] Therefore, it is necessary to design a regenerative glass crucible furnace to solve the above problems. Utility Model Content
