Embodiment Construction

[0042] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0043] figure 1 It is a cross-sectional explanatory view of a molten glass supply device according to an embodiment of the present invention, figure 2 It is a top view of the supply duct of this molten-glass supply apparatus. Such as figure 1 As shown, the molten glass obtained by the molten glass production area 6 is transported from the molten glass production area 6 to the molten glass supply part 5 of the float glass forming device 7 via the supply pipeline 1, and is transported from the molten glass supply part 5 to Float glass 12 is molded on the molten tin 11 in the float bath 10 . More specifically, the molten glass obtained by dissolving glass raw materials in the molten glass production area 6 is further sufficiently clarified in the molten glass production area 6, and is cooled to a predetermined viscosity suitable for forming float glass. After the te...

Abstract

A molten glass supply device capable of supplying high-quality float glass not containing bubbles, etc. A molten glass supply device is provided with: a supply pipe for transferring molten glass from a glass forming region to a molten glass supply section of a float bath; and a tweel provided to the molten glass supply section of the float bath so as to face the opening of the supply pipe and adjusting the amount of supply of molten glass to the float bath. The opening of the supply pipe is disposed at a position lower than the level of the molten glass in the glass forming region. The supply pipe has a fan-shaped section which spreads in the left-right direction over a predetermined angle while extending toward the opening at the front end of the supply pipe, and the fan-shaped section has a cross-sectional shape flattened gradually toward the opening and is tilted upward.

Description

technical field [0001] The present invention relates to an apparatus for supplying molten glass to a float tank of a float glass manufacturing apparatus. Background technique [0002] In the float glass, the molten glass produced in the molten glass production area is transported to the molten glass supply part of the float glass production device, and the molten glass transported to the molten glass supply part is supplied onto the molten tin in the float tank, Thus forming a ribbon glass (glass ribbon). As this molten glass conveying device, a launder-like molten glass flow channel with an open top is generally used. Patent Document 1 discloses that the molten glass produced in the molten glass production area is transported to the float tank glass production through a supply pipeline. The device of the molten glass supply part of the device. [0003] The molten glass conveying device, such as Figure 4 As shown, the supply pipe 18 provided with a funnel-shaped expansion...
