<p><P>PROBLEM TO BE SOLVED: To provide a molten glass supply apparatus which secures appropriately-communicating constitution in a plurality of agitation vessels on the way of a supply passage of molten glass to obtain a sufficient agitation operation and prevents the quality and yield deteriorations of glass molded articles caused by the existence of heterogeneous phases. <P>SOLUTION: The molten glass supply apparatus 1 is provided with a fusion kiln 2 being a supply source of the molten glass, and the supply passage 4 for supplying the molten glass flowing out of the kiln 2 to a molding device 3. On the way of the supply passage 4, a plurality of agitation vessels K1 and K2 are disposed adjacently to each other in the upstream and downstream directions. Among at least two adjacent agitation vessels K1 and K2, either one of the upper or lower part of the upstream vessel K1 is provided with an inflow opening M1 while the other is provided with an outflow opening N1, and the inflow and outflow openings M2 and N2 of the downstream vessel K2 are provided in the same top and bottom relationship as those of the upstream vessel K1. Further, the outflow opening N1 of the upstream vessel K1 is connected through a communication channel, to the inflow opening M2 of the downstream vessel K2. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
