A feeding system for making optical fiber preform

Abstract

The invention provides a feeding system for optical fiber preform production. The feeding system comprises a gas-liquid mixing part, an ultrasonic atomizing part, a heating part, a torch lamp and a torch lamp position adjusting platform, wherein the gas-liquid mixing part comprises a liquid material charge pipe, a gas carrying charge pipe, a liquid flowmeter and a gas flowmeter; the ultrasonic atomizing part comprises an atomizing part charge pipe and an ultrasonic generator for atomizing a gas-liquid mixture in the atomizing part charge pipe; the atomizing part charge pipe is communicated with a middle conveying charge pipe which is communicated with both the liquid material charge pipe and the gas carrying charge pipe; the heating part comprises a heater used for evaporating the atomized gas-liquid mixture into mixed gas; the atomized gas-liquid mixture is conveyed to the heater through a heating part charge pipe communicated with the atomize part charge pipe; the torch lamp is used for conducting sedimentation of the mixed gas on an optical fiber preform; the mixed gas is conveyed to the torch lamp through a final charge pipe communicated with the heating part charge pipe; the torch lamp position adjusting platform is used for bearing the ultrasonic atomize part, the heating part and the torch lamp. The feeding system has the advantages that the vapor conveying pipeline is short; the evaporation pressure is stable; the leakage possibility is low; the position of the torch lamp is convenient to adjust.

Description

technical field [0001] The invention belongs to the technical field of communication and signal transmission, and in particular relates to a feeding system for making optical fiber preform rods. Background technique [0002] In recent years, with the rapid development of the information industry, the application of high-bandwidth and long-distance data transmission has become more and more extensive, and the market demand for optical fibers has increased. At the same time, the competition in the optical fiber industry has become increasingly fierce. Low cost, better design solutions, and higher production efficiency to win the competition have become issues that all competitors must think about. As the most important upstream raw material in optical fiber manufacturing, optical preform directly determines the quality and cost of optical fiber. Moreover, while reducing costs and improving efficiency, the use of new materials that are energy-saving, environmentally friendly, ...
