Abstract
The present invention provides devices for glass melt devlivery and methods for using these devices. In these devices, a delivery nozzle comprising at least one platinum group metal material is directly heated by electricty. To facilitate heating, a cylindrical heating ring is mounted in ceramic base. The device's construction ensures a regulatable heating of the nozzle and the melted glass flux.
Claims17
A glass melt delivery device comprising:
- a. a ceramic component;
- b. a cylindrical heating ring, wherein said cylindrical heating ring is located within the ceramic component;
- and
- c. a delivery nozzle, wherein said delivery nozzle comprises at least one platinum group metal and comprises a cylindrical end piece and a conical funnel, wherein said heating ring and said cylindrical end piece are located a distance apart that is from about one to about three times the wall thickness of the cylindrical end piece.

A device for delivering glass melt comprising:
- a. a ceramic component, wherein in said ceramic component are slits;
- b. a nozzle, wherein said nozzle comprises a conical funnel shaped part, a cylindrical end piece, and said funnel shaped part is located adjacent to said cylindrical end piece;
- c. an upper axial ring;
- d. a lower axial flanged ring;
- e. a take-off-bar located distal to the end of the cylindrical end piece that is adjacent to the conical funnel shaped part and adjacent to said lower axial flanged ring;
- f. a cylindrical heating ring located within said ceramic component, in contact with said lower axial flanged ring, and coaxial to said cylindrical end piece. wherein said heating ring and said cylindrical end piece are located a distance apart that is from about one to about three times the wall thickness of the cylindrical end piece;
- and
- g. at least two current feeds sheets, wherein said current feed sheets are attached to said coaxial cylindrical heating ring and arranged radially on opposite sides and axial to the lower flanged ring and pass through said slits.
