Abstract
Official abstract text for this publication.
It is an object of the present invention to provide a vacuum degassing apparatus configured so as to be capable of carrying out more simply exchange operation for an extension pipe made of heat-resisting metal and immersed in molten glass. The present invention includes a vacuum housing, a vacuum vessel, an introduction pipe and a discharge pipe which are assembled by a plurality of bricks, and an extension pipe connected to at least one of the introduction pipe and the discharge pipe and made of heat-resisting metal. The extension pipe is constituted by a base end portion, a body portion formed so as to be continuous to the base end portion, and a sealing flange extending from an outer peripheral side of the body portion.
First claim
Opening claim text (preview).
What is claimed is: 1. A vacuum degassing apparatus for molten glass, comprising: a vacuum housing; a vacuum vessel disposed in the vacuum housing such that molten glass is introduced into the vacuum vessel; an introduction pipe positioned in the vacuum housing and connected to an upstream side of the vacuum vessel such that the molten glass is introduced into the vacuum vessel; a discharge pipe positioned in the vacuum housing and connected to downstream side of the vacuum…
