Description
Technical field
The present invention relates to the washing unit of crystal reaction tube, it is specifically related to the automatic tube cleaner of crystal reaction tube and automatically washes pipe method.
Background technology
Along with the develop rapidly of optical fiber industry, the specification of quality of optical fiber is also more and more higher, and optical blank is as the starting material of optical fiber production, its manufacturing processed and quality are particularly important, and the service efficiency of therefore relevant with the manufacture of optical blank equipment also needs further raising.
Optical fiber is generally manufactured by vapor deposition method; steam and the oxygen of high purity metal halogenide react; form some oxide fine particles; these oxide fine particles can be deposited on silica tube; optical blank is formed by sintering; form bare optical fiber through towing, after coating processes, bare optical fiber through painted, be wound around, form the optical cable that everybody sees after the technique such as coated, therefore the quality tool of optical blank is had a significant impact by silica tube. If there is tiny crack on optical blank surface, the process of towing inevitably is transformed into the tiny crack on bare optical fiber surface, when the outside stress that bare optical fiber is subject to is greater than the expansion critical stress of these tiny cracks, tiny crack can increase gradually and finally causes fibercuts. Owing to having space between interior painting coating and bare optical fiber, when being subject to certain external force, first coating place ruptures, and then causes bare optical fiber to rupture, and surface contamination can reduce bare optical fiber and the bonding tightness of interior painting coating, therefore ensure the cleaning very important of bare optical fiber.
In order to ensure the cleaning of optical blank, crystal reaction tube cleans a very important technical process in just having become prefabricated rods to make. At present, the clean of crystal reaction tube is convert, with deionized water, the method that the cleaning of a certain proportion of alkali is deoiled, deionized water converts a certain proportion of acid cleaning polishing to be cleaned by the inwall of crystal reaction tube by optical fiber industry. Before cleaning by manually reaction tubes being put into such cleaning chamber, clean after a few hours by equipment automatic or manual, more manually take out to blow and sweep oven dry, then drop into next step production, this kind of method time is longer, and equipment fails efficiently to utilize, and level of automation is low.
It thus is seen that there is the low problem of level of automation in current reaction tubes washing unit.
Summary of the invention
