Description
Technical field
This utility model relates to a kind of optical fiber producing apparatus, particularly relates to a kind of drawing optical fibers annealing insulation device.
Background technology
In optical fiber production manufacturing, the design of optical fiber production process flow process is to ensure that the key factor of optical fiber quality.In general, optical fiber production flow process mainly includes that high temperature melting, annealing insulation, natural cooling, pressure cooling, optical fiber coating, PMD rub several processes such as torsion, traction take-up with the hands.Wherein annealing insulating process is to preferably enable the optical fiber under the condition of high temperature obtain enough Stress Release, promoting the performances such as the attenuation of optical fiber, warpage, intensity.The annealing insulation device that current most of manufacturers use is closed ceramic induction heated type annealing insulation construction, the annealing insulation device of this structure easily forms the oxide powder of accumulation after high-temperature oxydation in earthenware, easily bring intensity hidden danger to optical fiber production, this kind of structure need to be lowered the temperature in advance when cleaning simultaneously, the consuming time is longer, affects production efficiency.
In view of drawbacks described above, the design people's the most in addition research and innovation, to founding the annealing insulation device of a kind of new structure so that it is improve cleaning efficiency while guaranteeing optical fiber quality, promote fiber manufacturing efficiency.
Utility model content
For solving above-mentioned technical problem, the purpose of this utility model is to provide drawing optical fibers annealing insulation device that is a kind of easy to clean and that can improve optical fiber production efficiency and quality.
Drawing optical fibers annealing insulation device of the present utility model, including outer tube body and interior tube body, said inner tube body is arranged in outer tube body, described outer tube body includes can the outer tube body top of folding and outer tube body bottom, it is wound with heating-wire on the lateral surface of said inner tube body, being provided with heat-insulation layer on the medial surface of described outer tube body, the medial surface of described heat-insulation layer is provided with thermal insulation layer, the junction being positioned at outer tube body top and outer tube body bottom of described outer tube body is provided with refractory seals bar.
Further, drawing optical fibers annealing insulation device of the present utility model, described outer tube body be cross section be circular round tube, described outer tube body top and the semicircle body that outer tube body bottom respectively cross section is semi-circular shape.
Further, drawing optical fibers annealing insulation device of the present utility model, the lateral surface on described outer tube body top and the lateral surface of outer tube body bottom are respectively provided with handles.
Further, drawing optical fibers annealing insulation device of the present utility model, described thermal insulation layer is made up of heat insulation soil.
Further, drawing optical fibers annealing insulation device of the present utility model, described heat-insulation layer is made up of high-temperature-resistant thermal-insulation cotton.
By such scheme, this utility model at least has the advantage that compared with existing annealing insulation device, drawing optical fibers annealing insulation device of the present utility model can not only play annealing heat insulation effect, guarantee that fiber stress discharges, more can stage produce terminate after directly open outer tube body, thus be cleaned its inside arranging, easy to use and cleaning effect good, thus improve the intensity of optical fiber, reduce the use manufacturing cost of optical fiber.Time specifically used, optical fiber is arranged on the inside of interior tube body by operator, and by the heating-wire on interior tube body lateral surface, the optical fiber in interior tube body is heated to about 900-1100 DEG C, it is ensured that fiber stress discharges.Wherein heating-wire is separated by thermal insulation layer with heat-insulation layer.Heat-insulation layer is looped around outside thermal insulation layer, plays heat insulation effect.The outer tube body top of half-ring and outer tube body bottom use refractory seals bar to seal, and prevent peripheral air from flowing into disturbance optical fiber production status, play sealing protective effect.
Described above is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be practiced according to the content of description, below with preferred embodiment of the present utility model and coordinate accompanying drawing describe in detail as after.
