Electric crucible furnace equipment for glass dissolution and manufacturing method thereof

Abstract

The invention discloses electric crucible furnace equipment for glass dissolution and a manufacturing method thereof. The electric crucible furnace equipment comprises a furnace body, wherein multiple transformers are arranged at the top of the furnace body; the transformers are externally connected with an electric control cabinet; the electric control cabinet is connected with the transformers and the electric equipment of the furnace body respectively; a crucible is arranged on the innermost layer of the furnace body; a four-layer thermal insulation structure is arranged outside the crucible and comprises a first-level thermal insulation brick layer, a second-level thermal insulation brick layer, a thermal insulation cotton layer and a steel cover layer sequentially from inside to outside; multiple heating rods are inserted into the furnace body; the ends of the heating rods stretching out of the furnace body are connected with the output ends of the transformers; and a thermocouple is inserted into the middle of the top of the furnace body. With the four-layer thermal insulation structure, the electric crucible furnace equipment disclosed by the invention effectively avoids the heat loss in the furnace; three transformers outputting different voltages provide three different working environments of low temperature, middle temperature and high temperature to the heating of the heating rods; and the moisture is removed sufficiently by the crucible and uniform and effective heating is obtained through low-temperature thermal insulation and middle-temperature thermal insulation, the cracking of the crucible is avoided, and the service life of the crucible is prolonged.

Description

[0001] technical field [0002] The invention relates to an electric crucible furnace equipment, in particular to an electric crucible furnace equipment for dissolving glass and a manufacturing method thereof. Background technique [0003] Currently, electric furnaces and gas-fired crucible furnaces are used for glass melting. Electric furnaces use electric energy as heating energy. They have good production stability and are suitable for single raw material production. , It takes a long time, which is not conducive to quickly respond to market changes; the gas-fired crucible furnace uses gas as the heating energy, and the production stability is poor. Each crucible is discharged, and the raw materials can be changed at any time for production. It has good flexibility and can quickly respond to market changes. Electric crucible furnace combines the advantages of electric furnace and gas crucible furnace, using electric energy as heating energy, production stability is guaran...
