US 6,582,571 B2 · Diaphragm cell cathode structure

Abstract

An electrolytic cell comprising a walled enclosure including a cathode sidewall has busbar structure external to the cell. The busbar structure can include a gird bar releasably secured at the sidewall. It also may include a foraminous interface member between the gird bar and the sidewall, as well as have a small cathode busbar member on the sidewall. The small busbar member is typically located above and adjacent to the gird bar. Particularly when the gird bar and foraminous interface member are present, there can be internal support members for the cathodes directly secured to the inside face of the cathode sidewall. Furthermore, intercell connection may be handled directly to the outside face of the cathode sidewall. The overall structure can provide reduced potential for sidewall stress corrosion cracking, reduced cathode manufacturing cost, and accommodation of stress relief for the cathode weldment.

Dependent claims

An electrolytic cell wherein the cell comprises a walled enclosure providing at least one cathode sidewall for said enclosure and with there being cathode busbar means external to said cell, including an outer gird bar extending along an outside face of said cathode sidewall, and interior cell structure at an inside face of said cathode sidewall which includes cell cathodes incorporating support members, the improvement in said structure comprising:

a solid and elongated outer gird bar member secured at said sidewall outside face by fastening means at the ends thereof securing said gird bar member to said sidewall;
and
internal support members supporting said cathodes situated within said electrolytic cell, with said internal support members being directly secured to said sidewall inside face.
