Multifunctional quartz glass continuous melting furnace

Abstract

The invention discloses a multifunctional quartz glass continuous melting furnace. The multifunctional quartz glass continuous melting furnace comprises a furnace body and a crucible, wherein the crucible is fixedly mounted in the furnace body; a first heating ring and a second heating ring are fixedly mounted on the outer side of the crucible; a heat-insulating layer is arranged on the outer sideof each of the first heating ring and the second heating ring; a core rod is arranged in the crucible; one side of the core rod is fixedly connected with a pressure sensor; the top end of the core rod is fixedly connected with a furnace cover and a gas delivering pipe; the top end of the furnace cover is connected with a feeder; a forming mold is fixedly arranged at the bottom end of the core rod; a forming outlet is formed in the bottom end of the forming mold; a cooling device is fixedly mounted at the bottom end of the forming outlet; and the cooling device comprises a cooling water jacket, a water storage tank and a cooling pipeline. By the multifunctional quartz glass continuous melting furnace, the problems that the reaction is insufficient due to insufficient heating of quartz sandmaterials in the crucible by an existing heating mode, and most of quartz glass is low in cooling forming speed in the prior art can be effectively solved, and the practical value is relatively high.

Description

technical field [0001] The invention relates to the technical field of quartz processing, in particular to a multifunctional continuous melting furnace for quartz glass. Background technique [0002] At present, various types of electric heating continuous melting furnaces used in the production of quartz glass tubes in China adopt fixed crucibles. The glass melting process refers to the qualified batch materials being heated at high temperature to form uniform, defect-free glass that meets the forming requirements. The process of the liquid, from heating the quartz sand material to melting the quartz glass melt, can be divided into five stages, namely the silicate formation stage, the glass formation stage, the clarification stage of the glass liquid, the homogenization stage of the glass liquid, the glass liquid The cooling stage of the liquid, so the heating temperature in the furnace is closely related to these five stages. Existing continuous furnace heating mostly ado...

AI Technical Summary

Problems solved by technology

Existing continuous furnace heating mostly adopts single-electrode heating, that is, a heating net is only set on the outer circumference of the crucible, and the crucible is heated by radiation heat transfer. The existing heating method is insufficient for heating the quartz sand material in the crucible, so that its reaction is not enough sufficient, and most of the quartz glass cooling molding speed in the prior art is slow
