Problems solved by technology
[0016] While additionally achieving the purpose of retaining the liner under sufficient compressive force, existing tank shell designs and the design alternatives proposed in US2861036 and US4421625 suffer from the disadvantage of having a large external structure
This structure limits the area of the cathode that can be accommodated in an electrolyser of given external dimensions

Embodiment Construction
[0044] In the following description, specific details are given to provide examples of claimed subject matter. However, the examples described below are not intended to define or limit the claimed subject matter. It will be apparent to those skilled in the art that many variations of the specific embodiments are possible within the scope of the claimed subject matter.
[0045] Figure 4 and Figure 5 An aluminum pot shell 10 (sometimes referred to as "pot 10" or "tank shell 10") is shown with some of its components removed for clarity and located in a single pot compartment according to an embodiment . The reader will appreciate that the tank shell 10 may be equipped with support structures, superstructure, collector bars and busbars for the production of aluminum by the Hall-Eroux process. These common elements for electrolyzers are omitted from the following description unless necessary to clarify specifics of the examples.
[0046] The electrolyzer shell 10 includes a ...

Abstract
An aluminum reduction cell, comprising: (a) a shell structure comprising a pair of longitudinally extending sidewalls, a pair of transversely extending endwalls, a bottom wall, and an open top having an upper edge; (b) a transverse support structure comprising a plurality of transverse bottom beams located under the shell structure and extending transversely between the sidewalls, each of the transverse bottom beams having a pair of opposed ends; and (c) a plurality of compliant binding elements fixed to the transverse support structure, each extending vertically along an outer surface of one of the sidewalls, for applying an inwardly directed force said sidewall; wherein the compliant binding elements are in the form of cantilever springs, each comprising a metal member having a lower end which is secured to the transverse support structure, and a compliant, upper free end which is movable inwardly and outwardly in response to expansion and contraction of the shell structure.
Description
[0001] Cross References to Related Applications [0002] This application claims priority and benefit to US Provisional Patent Application No. 62 / 082,898, filed November 21, 2014, the contents of which are incorporated herein by reference. technical field [0003] The present invention relates to a method for increasing the reaction area within the footprint of an existing tank shell to increase productivity or reduce the capital cost per ton of capacity of a Hall-Heroult series of aluminum electrolysis cells. In another aspect, the present invention relates to an aluminum electrolytic cell structure and a tank shell for realizing the aluminum electrolytic cell structure. Background technique [0004] Aluminum is produced using the Hall-Eroux process. Traditional plants would employ hundreds of pots connected in series and housed in long buildings or pot lines, along with transformers, rectifiers, busbars, cranes, tapping equipment and other auxiliary equipment. [0005] A...
