Electrode compartment

Claim 2

In an electrode compartment of an electrolyzing chamber surrounded by frame members, said electrode compartment comprising at least one lead bar for electrically connecting an electrode to a power source and an electrode held in communication with the lead bars, means for feeding an electrolyte in a lower frame member and means for discharging an electrolyzed product in an upper frame member to result in lifting flow of the electrolyte in the electrolyzing chamber, an improvement wherein said at least one lead bar is inserted through the bottom of said lower frame in the vertical direction and held substantially parallel to the upward flow of said electrolyte in the electrolyzing chamber and wherein said electrode is mechanically held by fitting means mounted on said at least one lead bar to thereby electrically connect said at least one lead bar to said electrode, and wherein said at least one lead bar is substantially quadrilateral in section and said fitting means include a quadrilateral hollow into which said at least one lead bar is inserted for continuous contct about the periphery of said lead bar.

Claim 3

An electrode compartment according to claim 1 wherein said lower frame is hollow to form a passage for feeding said electrolyte and includes means for feeding the electrolyte, said means for feeding comprising an inlet in said frame for feeding the electrolyte into the hollow of said lower frame and holes on said lower frame for feeding said electrolyte into said electrolyzing chamber; and said upper frame is hollow to form a passage for discharging the electrolyzed product and includes means for discharging the electrolyzed product, said means for discharging comprising holes on said upper frame for discharging the electrolyzed product into the hollow part and an outlet in said frame for discharging the electrolyzed product from the hollow of said upper frame.

Claim 4

In an electrode compartment of an electrolyzing chamber surrounded by frame members, said electrode compartment comprising at least one lead bar for electrically connecting an electrode to a power source and an electrode held on said lead bars, means for feeding an electrolyte in a lower frame member and means for discharging an electrolyzed product in an upper frame member to result in lifting flow of the electrolyte in the electrolyzing chamber, an improvement wherein the lead bars are inserted through the bottom of said lower frame in the vertical direction and held substantially parallel to the upward flow of said electrolyte in the electrolyzing chamber and wherein said electrode is mechanically held by fitting means mounted on said lead bars to thereby electrically connect said lead bars to said electrode, and wherein said fitting means is cross shaped in section and has a longitudinal hollow formed therein, said lead bar being surrounded by said hollow, and wherein the fitting means are arranged in the vertical direction and are substantially parallel to the lifting flow of the electrolyte in the electrolyzing chamber and one of said electrodes is mechanically held on each side surface of said fitting means to provide a space between the electrodes, and the electrodes are electrically connected to the lead bars by means of said fitting means.

Claim 5

In an electrode compartment of an electrolyzing chamber surrounded by frame members, said electrode compartment comprising at least one lead bar for electrically connecting an electrode to a power source and an electrode held on said lead bars, means for feeding an electrolyte in a lower frame member and means for discharging an electrolyzed product in an upper frame member to result in lifting flow of the electrolyte in the electrolyzing chamber, an improvement wherein the lead bars are inserted through the bottom of said lower frame in the vertical direction and held substantially parallel to the upward flow of said electrolyte in the electrolyzing chamber and wherein said electrode is mechanically held by fitting means mounted on said lead bars to thereby electrically connect said lead bars to said electrode, and wherein said fitting means is cross shaped in section and has a longitudinal hollow formed therein, said lead bar being surrounded by said hollow, and wherein the fitting means are arranged in the vertical direction and are substantially parallel to the lifting flow of the electrolyte in the electrolyzing chamber and one of said electrodes is mechanically held on each side surface of said fitting means to provide a space between the electrodes, and the electrodes are electrically connected to the lead bars by means of said fitting means.

Claim 6

An electrode compartment according to claim 1, or 3 wherein at least one reinforcing means having a plate shape is arranged between the lead bars and is substantially parallel to the lead bars in the electrolyzing chamber and an electrode is mechanically held on each side surface of the reinforcing means.
