Abstract
An apparatus for manufacturing a glass base material, which is a base material of an optical fiber, the glass base material having a core rod as a central axis, comprises a holding unit having a plurality of scroll chucks connected in series along the core rod for holding an end of the core rod; and a burner that hydrolyzes a gas material, which is a base material of the glass base material, into glass particles and accumulates the glass particles around the core rod to form the glass base material.
Claims27
An apparatus for manufacturing a glass base material, which is a base material of an optical fiber, said glass base material having a core rod as a central axis, comprising:
- a holding unit having a plurality of scroll chucks connected in series along said core rod for holding an end of said core rod;
- and
- a burner that hydrolyzes a gas material, which is a base material of said glass base material, into glass particles and accumulates said glass particles around said core rod to form said glass base material.
An apparatus for manufacturing a glass base material, which is a base material of an optical fiber, said glass base material having a core rod as an central axis, comprising:
- a burner that hydrolyzes a gas material, which is a base material of said glass base material, into glass particles and accumulates said glass particles around said core rod to form said glass base material;
- a chamber which accommodates said core rod and said burner;
- an air vent formed on a bottom sidewall of said chamber to intake a cleaning gas for cleaning inside said chamber;
- a filter formed inside said chamber, said filter located lower than said burner and higher than said air vent for regulating a flow speed distribution of said cleaning gas that flows from said air vent;
- and
- an air-regulating-plate formed inside said chamber, said air-regulating-plate located lower than said burner and higher than said air vent and having a plurality of holes to regulate a direction of a flow of said cleaning gas that flows from said air vent.
An apparatus for manufacturing a glass base material, which is a base material of an optical fiber, said glass base material having a core rod as a central axis, comprising:
- a burner that hydrolyzes a gas material, which is a base material of said glass base material, into glass particles and accumulates said glass particles around said core rod to form said glass base material;
- a chamber installed on a floor, said chamber accommodating said core rod and said burner;
- and
- a supporting unit formed on a bottom face of said chamber and contacting with said floor for supporting said chamber, said supporting unit comprising a fixed leg fixed on said floor and a plurality of movable legs which are movable with respect to said floor.
A method for manufacturing a glass base material, which is a base material of an optical fiber, said glass base material having a core rod as a central axis, comprising:
- hydrolyzing a gas material, which is a base material of said glass base material, into glass particles;
- accumulating said glass particles around said core rod to form said glass base material;
- intaking a cleaning gas into a chamber;
- regulating a flow speed distribution of said cleaning gas that flows into said chamber by a filter;
- and
- regulating a direction of a flow of said cleaning gas that passes through said filter.
