Abstract

The invention relates to the technical field of optical fiber preparation, and discloses a blast burner for manufacturing an optical fiber preform. The blast burner comprises a distribution ring, the distribution ring is movably sleeved with a lamp sleeve, and an outer ring in the distribution ring is annularly provided with an air hole 1. According to the blast burner for manufacturing the optical fiber preform, an annular groove I and an annular groove II communicate and are matched with the air hole I and an air hole II, so that oxygen and hydrogen conveyed from the air hole I and the air hole II are annularly sprayed out and mixed after being completely loaded in the annular groove I and the annular groove II, and are combusted to generate water which is mixed and reacted with silicon tetrachloride to generate silicon dioxide particles. Silicon dioxide particles are accumulated in the annular groove I and the annular groove II, silicon tetrachloride is liquid, friction force between the silicon tetrachloride and the silicon dioxide particles is larger, and the silicon tetrachloride is not prone to being accumulated in liquid holes, and the annular groove I and the annular groove II are annular grooves, so that the time needed for influencing the discharge amount of the silicon tetrachloride is longer when the silicon dioxide particles cause blocking, and the diameter stable state time can be prolonged when the equipment is used for preparing the preform.

Description

technical field [0001] The invention relates to the technical field of optical fiber preparation, in particular to a blowtorch for manufacturing optical fiber preform rods. Background technique [0002] Both the VAD and OVD optical fiber preforms are made by blowtorch, which is used to spray silicon tetrachloride, hydrogen and oxygen. At high temperature, the gases react chemically to generate silica particles, and the particles are deposited on the target through the heat surge effect. On the rod, the core and cladding of the powder prefabricated rod are formed, and the relative movement between the blowtorch and the target rod makes the silica fine particles deposited on the target rod layer by layer until the design weight and diameter are reached, and the optical fiber preformed rod is obtained. The intermediate product is to transport the preform rod, and then through the dehydration and sintering process, the transparent optical fiber preform rod can be obtained. [0...
