Abstract

The present application relates to a device and method for online repairing of a quartz muffle tube, and relates to the technical field of optical fiber preform rod manufacturing. The drive unit on the device is provided with a shaft, the drive unit is used to drive the shaft to rotate and move in the vertical direction, the detection unit is set on the shaft, which is used to detect the wall thickness of the muffle tube, the control unit It is used to judge whether there are cracks, holes and thin-walled areas in the muffle tube according to the collected thickness data. The repair unit includes a first repair piece and a second repair piece arranged on the shaft at intervals. The first repair piece is used to spray silicon Sol, the second repair part is used to spray glass particles, the second repair part is used to repair cracks and thin-walled areas on the muffle tube, and it is also used to assist the first repair part to repair holes on the muffle tube. The device provided by the application can timely detect problems such as thinning, cracks, and holes in the muffle tube, and repair the cracks and holes in time, which solves the problem of high cost and laborious replacement of the muffle tube.

Description

technical field [0001] The present application relates to the field of optical fiber preform manufacturing technology, in particular to an online repair device and method for a quartz muffle tube. Background technique [0002] With the rapid development of the optical communication industry, the industry of optical fiber preforms has also been greatly developed. At present, the two most commonly used manufacturing methods for manufacturing optical fiber preforms are axial vapor deposition (VAD, Vapor Axial Deposition) and external Chemical vapor deposition (OVD, Outside Vapor Deposition), both VAD and OVD production processes include deposition and sintering processes. First, opaque powder rods are deposited, and then transparent optical fiber preforms are generated after dehydration and sintering processes in a high-temperature heating furnace. , in this process, the most important and most critical structure is the muffle tube. Put the deposited powder rod into the quartz ...
