Abstract

The present disclosure related to an inert anode which is electrically connected to the electrolytic cell, such that a conductor rod is connected to the inert anode in order to supply current from a current supply to the inert anode, where the inert anode directs current into the electrolytic bath to produce nonferrous metal (where current exits the cell via a cathode).

First claim

What is claimed is:

1. An apparatus, comprising:
an anode body having at least one sidewall, wherein the sidewall is configured to perimetrically surround a hole therein, the hole having an upper opening in the top of the anode body and configured to axially extend into the anode body;
a bath having an upper surface; and
a pin having;
a first end connected to a current supply, and
a second end opposite the first end, wherein the second end extends down into the hole via the upper opening of the anode body, and wherein the second end is located above the upper surface of the bath.

2. The apparatus of claim 1 , further wherein the anode body comprises a ceramic material, a metal material, a cermet material, and combinations thereof.

3. The apparatus of claim 1 , further wherein the anode body is oval, cylindrical, rectangular, square, plate-shaped, triangular, pentagonal, hexagonal, and combinations thereof.

4. The apparatus of claim 1 , further wherein the pin is directly bonded to the anode body.

5. The apparatus of claim 1 , further wherein the first end of the pin is configured to fit into and be retained within a refractory material.

6. The apparatus of claim 1 , further wherein the length of the pin is sufficient to provide mechanical support to the anode body and sufficient to prevent corrosion on the pin inside the hole.

7. An apparatus, comprising:
an anode body having at least one sidewall, wherein the sidewall is configured to perimetrically surround a hole therein, the hole having an upper opening in the top of the anode body and configured to axially extend into the anode body;
a bath having an upper surface;
a pin having a first end connected to a current supply and a second end opposite the first end, wherein the second end extends down into the hole via the upper opening of the anode body, and wherein the second end is located above the upper surface of the bath; and
a filler retained in the hole between an inner surface of the anode body and the pin, wherein the filler is configured to promote electrical communication between the pin and the anode body.

8. The apparatus of claim 7 , further wherein the pin is configured to provide (a) a current supply to the anode body and (b) mechanical support to the anode body.

9. The apparatus of claim 7 , further comprising a member configured to extend from the second end of the pin, wherein the member has an end located below the upper surface of the bath.

10. The apparatus of claim 9 , further wherein the member is configured with the same dimensions as the pin.

11. The apparatus of claim 9 , further wherein the member has different dimensions than the pin.

12. The apparatus of claim 9 , further wherein the member is configured to overlap with the second end of the pin.

13. The apparatus of claim 9 , further wherein the member extends up around the pin inside the hole.

14. The apparatus of claim 9 wherein the cross-section of the pin is a: circle, oval, square, rectangle, pentagon, hexagon, and combinations thereof.

15. An apparatus, comprising:
an anode body comprising at least one sidewall circumscribing a hole therein, the hole having an upper opening in the top of the anode body;
a bath having an upper surface;
a pin extending down into the upper opening of the anode body, wherein the pin has a second end located above the upper surface of the bath,
a conductive member configured to attach to the pin and overlap with a portion of the second end of the pin, wherein the conductive member extends down into the hole to a position below the upper surface of the bath, and wherein the conductive member comprises a bath-resistant material; and
a conductive particulate material retained in the hole and configured to promote electrical communication between the pin, the conductive member, and the anode body.

16. The apparatus of claim 15 , wherein the overlap between the pin and the conductive member is not greater than 155 mm.

17. An apparatus, comprising:
an anode body comprising at least one sidewall circumscribing a hole therein, the hole having an upper opening in the top of the anode body;
a bath having an upper surface;
a pin extending down into the upper opening of the anode body, wherein the pin has a second end located above the upper surface of the bath,
a conductive member configured to attach to the pin, wherein the conductive member extends down into the hole to a position below the upper surface of the bath, and wherein the conductive member comprises a bath-resistant material; and
a conductive particulate material retained in the hole and configured to promote electrical communication between the pin, conductive member, and the anode body.

18. An apparatus, comprising:
an anode body comprising at least one sidewall circumscribing a hole therein, the hole having an upper opening in the top of the anode body;
a bath having an upper surface;
a pin extending down into the upper opening of the anode body, wherein the pin has a second end located above the upper surface of the bath,
a sheath, configured to surround the pin, wherein the sheath is configured to extend along the portion of the pin which resides inside the hole of the anode body; and
a conductive particulate material configured to be retained in the hole between the pin and the sheath to promote electrical communication between the pin, the sheath and the anode body.

19. An apparatus, comprising:
an anode body comprising at least one sidewall circumscribing a hole therein, the hole having an upper opening in the top of the anode body;
a bath having an upper surface;
a pin extending down into the upper opening of the anode body, wherein the pin has a second end located at a position inside the hole that is above the upper surface of the bath,
a member configured to attach to the pin, wherein the member extends down into the hole to a position below the upper surface of the bath;
a sheath, configured to surround the pin, wherein the sheath is configured to extend along the portion of the pin; and
a conductive particulate material configured to be retained in the hole between the pin, the sheath, and the member and promote electrical communication between the pin, the sheath, the member, and the anode body.

20. The apparatus of claim 19 , wherein the sheath resides inside the hole of the anode body.

21. The apparatus of claim 19 , wherein the sheath extends up above the surface of the anode body to a lower surface of a refractory material disposed opposite the upper opening of the hole in the top of the anode body.

22. The apparatus of claim 21 , wherein the sheath extends up into the refractory material.

23. The apparatus of claim 19 , wherein the sheath is configured to overlap with at least a portion of the conductive member.
