Abstract

Apparatus for conveying molten glass includes an electrical flange attached to a metallic vessel and an electrical flange support apparatus coupled to an electrode portion of the electrical flange and configured to prevent distortion of the metallic vessel and misalignment between the metallic vessel and an adjacent metallic vessel. A bracing assembly is also disclosed.

First claim

What is claimed is:

1. A glass manufacturing apparatus, comprising:
a metallic vessel configured to convey molten glass;
an enclosure disposed about the metallic vessel;
an electrical flange attached to the metallic vessel, the electrical flange comprising an electrode portion extending away from the metallic vessel and through the enclosure; and
an electrical flange support apparatus comprising a support bracket assembly mounted to the enclosure and comprising opposing attachment plates and a clamping member disposed between and engaged with the opposing attachment plates, the clamping member coupled to the electrode portion.

2. The glass manufacturing apparatus according to claim 1 , wherein the electrical flange support apparatus further comprises an electrode bracing assembly coupled to the electrode portion and engaged with a support member.

3. The glass manufacturing apparatus according to claim 2 , wherein the electrode bracing assembly comprises a bracing rod extending between the electrode portion and the support member and configured to maintain a predetermined separation between the electrode portion and the support member.

4. The glass manufacturing apparatus according to claim 3 , wherein the bracing rod comprises an electrically isolating spacer.

5. The glass manufacturing apparatus according to claim 4 , wherein the electrically isolating spacer contacts the support member.

6. The glass manufacturing apparatus according to claim 4 , wherein the bracing rod comprises a first portion and a second portion, the first and second portions engaged with and separated by the electrically isolating spacer.

7. The glass manufacturing apparatus according to claim 1 , wherein the clamping member comprises tabs extending from ends thereof, the tabs engaged with openings defined by the opposing attachment plates.

8. The glass manufacturing apparatus according to claim 7 , wherein the clamping member is further coupled to the opposing attachment plates by fasteners extending through the clamping member and the opposing attachment plates.

9. The glass manufacturing apparatus according to claim 1 , wherein the electrical flange support apparatus further comprises an adjustment assembly comprising an adjustment base mounted to the enclosure and coupled to the support bracket assembly by an adjustment member.

10. A glass manufacturing apparatus, comprising:
a metallic vessel configured to convey molten glass;
an electrical flange attached to the metallic vessel, the electrical flange comprising an electrode portion extending away from the metallic vessel; and
an electrode bracing assembly coupling the electrode portion to a support member, the electrode bracing assembly comprising a plurality of bracing rods and a clamp, wherein:
the clamp comprises a first clamping plate and a second clamping plate arranged on opposite sides of the electrode portion; and
each of the plurality of bracing rods extends from the first clamping plate to the support member.

11. The glass manufacturing apparatus according to claim 10 , wherein each of the of the plurality of bracing rods is configured to maintain a predetermined separation between the electrode portion and the support member.

12. The glass manufacturing apparatus according to claim 11 , wherein each of the of the plurality of bracing rods comprises an electrically isolating spacer.

13. The glass manufacturing apparatus according to claim 12 , wherein the electrically isolating spacer contacts the support member.

14. The glass manufacturing apparatus according to claim 12 , wherein each of the of the plurality of bracing rods comprises a first portion and a second portion, the first and second portions engaged with and separated by the electrically isolating spacer.

15. The glass manufacturing apparatus according to claim 10 , further comprising an enclosure disposed about the metallic vessel, the electrode portion extending through the enclosure, and a support bracket assembly mounted to the enclosure and coupled to the electrode portion.

16. The glass manufacturing apparatus according to claim 15 , further comprising an adjustment assembly comprising an adjustment base mounted to the enclosure and coupled to the support bracket assembly by an adjustment member.

17. The glass manufacturing apparatus according to claim 15 , wherein the support bracket assembly comprises opposing attachment plates and a clamping member disposed between and engaged with the opposing attachment plates, the clamping member coupled to the electrode portion.

18. The glass manufacturing apparatus according to claim 17 , wherein the clamping member comprises tabs extending from ends thereof, the tabs engaged with openings defined by the opposing attachment plates.
