Abstract
A diaphragm cell cathode case comprises a cathode case body and a cathode copper bar arranged therein. A plurality of cathode mesh bag combined units are arranged at intervals through concave net strips, and the cavity between the concave net strips and the cathode mesh bag combined units are anode cavities; each cathode mesh bag combined unit comprises a cathode mesh bag connected with the concave net strip, conductive square steels fixedly arranged on two inner walls of the cathode case body, a mesh bag support framework propped against the interior of the cathode mesh bag and electrically connected with the conductive square steels, and a conductive post playing an conductive role is fixed between the mesh bag support framework and the cathode mesh bag. The diaphragm cell cathode case removes conductive grids and adopts the structure of direct conduction of the conductive square steels, conductive support strips, conductive posts and the cathode mesh bag, thereby increasing effective space in the cathode mesh bag cavity, reducing hydrogen inflation degree in cathode liquid, increasing movement rate of the cathode liquid from top down, ensuring that the cathode mesh bag combined units are matched with the electrolyzers in the prior chlor-alkali industry, and finally prolonging the service life of the electrolyzer.
