Cone sintering device in optical fiber preform powder preparation and working method

Abstract

The invention relates to the technical field of optical fiber preforms, and discloses a cone sintering device in optical fiber preform powder preparation and a working method thereof. The cone sintering device comprises a first-layer barrel, a second-layer barrel and a third-layer barrel; the first-layer barrel is located below the second-layer barrel; the second-layer barrel is located below thethird-layer barrel; and a limiting groove is formed in the bottom surface of the first-layer barrel. According to the cone sintering device in optical fiber preform powder preparation, hexagon socketscrew holes are formed and penetrate through the side wall of the first-layer barrel and the side wall of the second-layer barrel to extend into the side wall of the third-layer barrel, and the cone sintering device is designed in a multi-layer nested combination mode; the first-layer barrel, the second-layer barrel and the third-layer barrel are fixedly connected by inserting hexagon socket screws into the hexagon socket screw holes; when the hexagon socket screws are detached, the second-layer barrel and the third-layer barrel are fixedly connected through buckling connection of limiting blocks and clamping blocks, and the structural design that the device can be disassembled for maintenance is achieved.

Description

technical field [0001] The invention relates to the technical field of optical fiber preform rods, in particular to a cone portion sintering device and working method in the preparation of optical fiber preform rod powder bodies. Background technique [0002] The preparation and processing of optical fiber preform is the source and one of the most important steps of the entire optical fiber and cable production, because the manufacturing process of optical fiber preform affects the subsequent preparation of optical fiber. The core-clad ratio of the rod is consistent with the qualified optical fiber, and the time for forming the optical fiber preform fusion cone is shortened. It is necessary to pre-prepare a streamlined cone head at the drawing end of the optical fiber preform. [0003] The taper sintering device of the existing optical fiber preform inlet device is integrally welded, and the device does not have the ability to be disassembled and maintained, frequently flash...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a taper sintering device in the preparation of optical fiber preform powder body, which has the structural design of multi-layer nested combination, detachability, and the combustion interface of combustion gas and combustion-supporting gas. The advantages of uniform mixing, the small air outlet holes of the two gases are arranged alternately in each direction, solve the problem that the cone sintering device of the original imported equipment is integrally welded, the device does not have disassembly and maintenance, and frequent accidents occur during use. Tempering conditions, short device life, insufficient gas combustion problems
