Title:
DEVICE FOR STIRRING MOLTEN GLASS
Document Type and Number:
WIPO Patent Application WO/2010/098328
Kind Code:
A1
Abstract:
A molten-glass stirring device by which molten glass having a viscosity of 100-7,000 dPa∙s is stirred in a molten-glass conveyance pipe through which the molten glass is conveyed at a rate of 1-50 m3/hr∙S (wherein S is the sectional area of the conveyance pipe). The molten-glass stirring device is composed of a rotatable center shaft and a stirring part disposed on the center shaft. The stirring part is composed of lateral stirring blades and vertical stirring blades, each blade comprising a platy object. The lateral stirring blades have been disposed so that the longer sides are perpendicular to the center shaft and the shorter sides are inclined toward the axial direction of the center shaft at 10-70 degrees. The vertical stirring blades have been disposed so that the longer sides are parallel to the center shaft and are located in positions that define the periphery of the stirring part. When the diameter of the molten-glass conveyance pipe in the portion where the stirring part has been disposed is expressed by D1 (mm) and the maximum diameter of the periphery of the stirring part is expressed by D2 (mm), then D1 and D2 satisfy 0.8×D1≤D2≤0.98×D1.
