SOOT REMOVING APPARATUS FOR MCVD-PROCESS AND SOOT REMOVING ROD FOR THE SAME

摘要

soot removal device according to the present invention is discharged from the MCVD process, when the quartz tube for optical fiber preform manufacture, An apparatus to prevent the silica soot is deposited on the inner tube for the exhaust, and is installed to contact the inner wall of the inner tube, the soot body is removed the rod is provided with at least one joint such that a partially folded; And naedorok scrape the inner wall of the soot of the inner tube rotation means for rotating the soot removal rod; characterized in that it comprises a ; In addition, according to the present invention, when MCVD process for producing an optical fiber preform In removing the soot rod is provided in the exhaust tube for silica soot is discharged from the quartz tube so as to prevent the laminate in the exhaust tube, the body is partially folded, so that at least one joint is provided for the alignment error of the exhaust tube removing the soot rod is provided, characterized in that the compensation.
