| titleOfInvention | Optical fiber wire drawing furnace graphite spare evacuation seals up and deposits device |
| abstract | The utility model relates to a seal up and deposit the device, concretely relates to optic fibre wire drawing stove graphite piece evacuation seals up and deposits device. Including the PE vacuum bag, the trachea that connects in the PE vacuum bag dress extends PE vacuum bag open-top and connects dress with nitrogen gas jar gas outlet, and PE vacuum bag bottom is provided with the vacuum bleeder valve, the vacuum bleeder valve connects dress with the evacuation pump, and PE vacuum bag open-top seals through the plastic packaging machine, and the device has the graphite spare in the PE vacuum bag, the trachea extends to lower part in the PE vacuum bag. The device has the advantages of strong air isolation protection, simple structure, convenient use, good storage quality, long service life of the graphite piece, capability of avoiding the exposure, storage, wetting and oxidation of the graphite piece, capability of ensuring the standard drawing production quality and effectively reducing the manufacturing cost of the optical fiber; the problem of current graphite spare expose deposit very easily wet that leads to, its inside easy steam that produces when reusing, the surface is easy to oxidize and is likepowder or even appear the hole, shortens graphite spare life, increases manufacturing cost is solved. |
