Melting device for glass fiber production

Abstract

The invention discloses a melting device for glass fiber production. The melting device comprises a channel-type melting tank. The upstream end of the melting tank is a melting zone, and a closed feeding mechanism is arranged at the port of the upstream end. The downstream end of the melting tank is provided with a melting-down zone, the tail end of the melting tank is provided with a clarification tank, and a smoke exhaust pipeline is arranged at the top of the melting tank. and a vibration defoaming mechanism is arranged in the clarification tank. According to the invention, a large amount of volatile gas generated by high-temperature melting is effectively prevented from overflowing from a discharge port, so that the volatile gas is prevented from entering a working environment to cause irreversible damage to the respiratory system of a worker; and through vibration bubble removal, the bubble content of a molten glass solution is reduced, the quality of glass fibers is improved, the use amount of a clarifying agent is reduced, and the pollution to the nature is reduced.

Description

technical field [0001] The invention relates to the technical field of glass fiber production, in particular to a melting device for glass fiber production. Background technique [0002] Glass fiber is an inorganic non-metallic material with excellent performance. There are many kinds. Its advantages are good insulation, strong heat resistance, good corrosion resistance and high mechanical strength. It is made of glass balls or waste glass through high-temperature melting, wire drawing, winding, weaving and other processes. The diameter of its single filament is several microns to more than 20 microns, which is equivalent to 1 of a hair. / 20-1 / 5, each bundle of fiber precursors is composed of hundreds or even thousands of monofilaments, glass fibers are usually used as reinforcing materials in composite materials, electrical insulation materials and thermal insulation materials, circuit substrates and other national economies each field. [0003] Among them, high-strength ...

AI Technical Summary

Problems solved by technology

[0004] Most of the existing melting devices use open feeding. When continuously adding raw materials to the melting device, a large amount of volatile gas generated during the high-temperature melting process overflows from the opening, causing the volatile gas to enter the working environment. The respiratory system of the staff causes irreversible damage; in addition, the clarification tank in the existing melting device is naturally static to clarify and defoam, the defoaming efficiency is low and the defoaming effect is poor, and a large amount of clarifying agent is often required to assist clarification and defoaming. And a large number of clarifiers will cause pollution to the natural environment
