The sealing device with the nitrogen valve for the pyrolysis furnace for the production of carbon fibers from rayon fibers

摘要

The invention relates to the field of producing carbon fibers from rayon fibers, and in particular to devices for sealing the entrance and exit of the pyrolysis furnace, and may be used in the process for producing continuous band knotted or carbon materials.;The object of the utility model is the development of nitrogen release pyrolysis furnace with a sealing device, the technical result of using of which is to ensure a high degree of integrity, creating aerodynamic disturbances, maintaining the necessary pressure in the chamber, ensuring the release of the pyrolysis products through special nozzles, as well as ensuring the absence of the processed material stress capable of violating conditions of transportation and the integrity of the material.;The technical result in the implementation of the utility model is achieved by proposing a nitrogen shutter pyrolysis furnace with a sealing device, characterized in that it is designed as located on a rigged wheels a sliding carriage box body with cooling ribs and arranged to one side of the box body slotted flange for connection box housing to the working chamber of the pyrolysis furnace and the docking flange on the other side of the box body for connection of the sealing device while the sealing device is designed as a matching shaped connection flange flat case with a rigidly mounted on a flat body support pad for continuously moving the processed fiber through made in flat-type slot-like opening output the processed fiber outside the working space of the pyrolysis furnace, flat body of the sealing device is provided with a made of thermal strength fabric flexible inflatable nitrogen element covered by the top mounted on flat-type sleeve with an adjustable pin retaining plate in the form of a tube-shaped segment, the surface of the flexible inflatable nitrogen element coated carbon cloth, or silicone, or PTFE. The width of the slot-like outlet opening outside the treated fiber workspace pyrolysis furnace corresponds to the width of the processed fiber.
