Abstract
An improved means for connecting anode posts to diaphragm cell bases is described which utilized anode posts which are soldered at the lower end of each post in an opening in the cell base to provide a good electrical connection. A plastic sleeve is positioned on the anode post above the soldered connection, and sealed to the interior surface of the cell base to provide a liquid-tight seal.
Claims8
In an electrolytic cell comprised of a cell base having:
- a. an interior layer which provides an interior surface,
- b. a conducting layer which provides an exterior surface,
- c. a cell body secured to said cell base,
- 1. a plurality of diaphragm-coated cathodes secured to said cell body,
- d. a plurality of anodes, each anode comprising:
- 1. a metallic conductive surface secured to
- 2. an anode post, said anode post being secured to said cell base,
- 3. each metallic conductive surface being positioned adjacent to and parallel to at least one of said cathodes,
- e. and current conducting means secured to said exterior surface,
- characterized by the improvement which comprises in combination,
- f. soldered connections between each of said anode posts and said cell base in said separate opening for each anode post in said cell base, and
- g. a plastic sleeve secured and sealed to the lower portion of each of said anode posts above said soldered connection, and
- h. liquid-tight sealing means between said anode post, said plastic sleeve and said interior layer for each of said anode posts, whereby inhibition of crevice corrosion and electrolytic attack upon said anode post is obtained.
