Abstract

The invention provides a device for continuously preparing optical fiber preform rods and achieving drawing. The device comprises a preform rod preparation unit and a drawing furnace, the preform rodpreparation unit is internally provided with a degassing sintering unit, and the degassing sintering unit comprises heating devices arranged in a degassing sintering cavity of the degassing sinteringunit; a core-layer blow torch and a covering-layer blow torch are arranged above the degassing sintering unit; the preform rod preparation unit is provided with an upper tail gas exhaust pipe, and thelower portion of a deposition chamber is correspondingly provided with a lower exhaust pipe; a driving mechanism, a flame polishing device, the drawing furnace, a coating device, a curing device anda traction wheel are sequentially arranged below the preform rod preparation unit. According to the device, by specially designing a blow torch system, a preform rod motion system and the like of theoptical fiber preform rods, the optical fiber preform rods can be continuously prepared, and meanwhile the prepared optical fiber preform rods are drawn into optical fibers online.

Description

technical field [0001] The invention belongs to the technical field of optical fiber preform production and manufacturing, and in particular relates to a device and method for continuously preparing and drawing optical fiber preforms. Background technique [0002] At present, the preparation of optical fiber preform and fiber drawing are two independent processes, that is, the finished preform is prepared in the optical fiber preform workshop or company, and then sent to the optical fiber drawing workshop or company to be drawn into optical fiber. Optical fiber preform is the most important and critical raw material in the fiber drawing process, which consists of a core rod and an outer cladding. From the perspective of the drawing process, the optical fiber preform can be divided into three categories according to the combination of the core rod and the outer cladding: solid rod, RIC rod (Rod inCylinder) and quartz sand online cladding rod. Quartz sand on-line cladding rod...
