Device for trapping and removing gas bubbles from a glass manufacturing chamber
Abstract
Abstract A GLASS MANUFACTURING CHAMBER CONTAINS A REFRACTORY CERAMIC LINING WHICH SUPPORTS THEREON A MOLTEN BATH OVER WHICH GLASS MAY BE FLOATED TO FROM A RIBBON OF GLASS. A DEVICE FOR TRAPPING AND REMOVING GAS BUBBLES FROM THE CHAMBER INCLUDES A BLOCK OF MATERIAL NONREACTIVE WITH THE MOLTEN BATH AND ANY ATMOSPHERE CONTAINED WITHIN THE CHAMBER. THE BLOCK HAS A FIRST PORTION SUBMERGED IN THE MOLTEN BATH AT A POSITION LOCATED ABOVE A PORTION OF THE REFRACTORY CERAMIC LINING. THE FIRST PORTION OF THE BLOCK HAS A PLURALITY OF GAS RECEIVING POCKETS FORMED THEREIN WHICH FACE THE REFRACTORY CERAMIC LINING. THE BLOCK OF MATERIAL ALSO HAS A SECOND PORTION TO WHICH THE FIRST PORTION IS CONNECTED. THE SECOND PORTION OF THE BLOCK HAS GAS COLLECTING AND GAS VENTING OPENINGS FORMED THEREIN WHICH ARE INTERCONNECTED WITH THE GAS RECEIVING POCKETS FORMED IN THE FIRST PORTION OF THE BLOCK. ANY GAS ISSUING FROM THE REFRACTORY LINING IS CAUGHT BY THE GAS RECEIVING POCKETS AND THEN VENTED THROUGH THE GAS COLLECTING AND GAS VENTING OPENINGS FORMED IN THE SECOND PORTION OF THE BLOCK.
