Drawing method and device for glass tank furnace

Abstract

The present invention is drawing method and device for glass tank furnace. The drawing device has material discharge port in the bottom of glass tank furnace, material discharge nozzle below the material discharge port, and drawing crucible below the material discharge nozzle for drawing. The drawing device has also glass liquid supplying channel connected with the glass tank furnace and provided with heat insulating layer, high speed roller set below the crucible to draw glass filament, flow rate controller fitted to the material discharge nozzle, and movable frame for fitting the replaceable material discharge nozzle in the material discharge port. The present invention has simple structure, easy replacement of the crucible, high temperature controlling precision, high production efficiency, high product quality and other advantages.

Description

technical field [0001] The invention relates to a glass fiber manufacturing technology, in particular to a glass tank kiln drawing method and a device thereof. Background technique [0002] Currently, there are two types of fiberglass manufacturing equipment. One is a drawing crucible set independently. When in use, it is necessary to continuously put glass ball raw materials or broken glass into the crucible, and then use electric heating to melt the solid glass raw materials, and only when the temperature reaches a certain temperature can the wire drawing production be carried out. The melting and heating step of solid glass raw material consumes a large amount of electric energy, which occupies a large proportion in the production cost of glass fiber. High energy consumption is the biggest defect of existing glass fiber production equipment. The glass ball is formed by cooling and solidifying the glass liquid produced by the existing glass tank kiln. The process of form...

Problems solved by technology

The melting and heating step of solid glass raw materials consumes a large amount of electric energy, which occupies a large proportion in the production cost of glass fiber. High energy consumption is the biggest defect of existing glass fiber production equipment.

The glass ball is formed by cooling and solidifying the glass liquid produced by the existing glass tank kiln. The process of forming the glass liquid into a ball not only requires process costs, but also wastes the heat energy carried by the glass liquid.

The other is pool kiln wire drawing, that is, the wire drawing drain plate is directly set on the feeding channel of the glass pool furnace for wire drawing; compared with the former wire drawing device, it saves most of the energy consumption, but it is difficult to control the temperature, and the drain plate It is not easy to replace, and the leak board must be made of expensive platinum material, which requires a particularly large investment
