Abstract

The invention discloses a quartz product preparation apparatus. The quartz product preparation apparatus comprises a blowtorch, a hearth, and a deposition bench; the blowtorch is arranged at a top ofthe hearth, the deposition bench is arranged below the blowtorch, an air-flow guiding apparatus is arranged at an outlet of the hearth, which is used for guiding high-temperature gas to form lateral air flow. The air-flow guiding apparatus is added at a specific position, influence of SiO2 dust and water vapor on surface of a quartz material in the hearth can be removed, and adsorption is reduced,so that the surface of the quartz material has a flat appearance.

Description

technical field [0001] The invention belongs to the field of quartz material preparation, and more specifically relates to a preparation device for quartz products. Background technique [0002] The quartz material used in the optical fiber preform has strict requirements on its appearance uniformity, bubble content, and impurity content. At present, the appearance uniformity of the quartz material prepared from high-purity quartz sand needs to be passed through subsequent multi-channel Process processing can meet the requirements. [0003] Gas smelting method is currently the main method for preparing quartz embryo body materials with natural quartz sand as raw material. This method is to melt the quartz sand in the furnace under the hydrogen-oxygen flame to form a quartz ingot with a larger diameter. The obtained quartz ingot is produced in different The cross-sectional dimensions deviate greatly in height. The surface of quartz products is uneven, with bubbles and high ...
