Problems solved by technology

[0002] As the existing continuous melting furnace is used longer, the heating power of the heater installed outside the crucible will gradually decrease, which will slow down the temperature rise of the continuous melting furnace and reduce the output. Finally, it will be overhauled because the temperature in the furnace cannot meet the production requirements. Reinstall the furnace; in addition, using a continuous melting furnace with a large crucible, it is difficult to heat the material, and the uniformity of the internal material temperature is poor, which affects product quality and production efficiency

Abstract

A continuous melting furnace relates to a continuous melting furnace used for producing quartz rods or quartz tubes, in particular relates to a continuous melting furnace adopting a large-size crucible, and aims to solve the problems that a current continuous melting furnace is low in heat utilization rate and short in service life. The continuous melting furnace comprises a furnace body, a large furnace lid, the crucible, a discharging table, a main heater resistance rod, a main heater positive electrode, a main heater negative electrode, a small furnace lid and a hopper, wherein the upper end of a core bar is mounted on the small furnace lid, and the lower end of the core bar is provided with a core head; a through hole is formed in the core bar; an adjusting thread is formed at the upper part of the core bar; the core bar is in threaded connection with a core bar adjustor above the small furnace lid; a booster heater positive electrode and a booster heater negative electrode are mounted on the large furnace lid; a booster heater resistance rod is positioned in the crucible and has two ends respectively connected with the booster heater positive electrode and the booster heater negative electrode. The continuous melting furnace provided by the invention has the advantages of high heat utilization rate and long service life.

Description

Technical field: [0001] The invention relates to a continuous melting furnace for producing quartz rods or quartz tubes, in particular to a continuous melting furnace for large-sized crucibles. Background technique: [0002] As the existing continuous melting furnace is used longer, the heating power of the heater installed outside the crucible will gradually decrease, which will slow down the temperature rise of the continuous melting furnace and reduce the output. Finally, it will be overhauled because the temperature in the furnace cannot meet the production requirements. Reinstall the furnace; in addition, using a continuous melting furnace with a large crucible, it is difficult to heat the material, and the uniformity of the internal material temperature is poor, which affects product quality and production efficiency. Invention content: [0003] The technical problem to be solved by the present invention is to provide a continuous melting furnace with high heat utili...
