Die bei elektrolytischen Zellen gewöhnlich verwendeten Elektroden haben den Nachteil, daß sie sich im Betriebe bald werfen. Infolge der Unebenheiten entstehen dann ungleiche S Entfernungen zwischen Diaphragma und Elektrode und dadurch ungleiche Strombelastungen der Elektroden. Auch tritt ein stärkerer Verschleiß an den überlasteten Stellen ein.The electrodes commonly used in electrolytic cells have the disadvantage that they will soon throw themselves in the factory. As a result of the unevenness then uneven ones arise S Distances between the diaphragm and the electrode and, as a result, unequal current loads of the electrodes. There is also greater wear and tear at the overloaded areas. ίο Es wurde nun ein Weg gefunden, diese Nachteile zu beheben, nämlich dadurch, daß man als Elektroden geformte Leiter, zweckmäßig aus Metallen, wieEisen, Kupfer, Ferromanganeisen, Siliciumeisen, Legierungen dieser Metalle oder aus Kohle, Mischungen von Kohle mit Beton usw., benutzt, die eine große Formstarrheit haben. Durch ihre zweckmäßig dach-, kuppel- oder U-förmige Gestalt wird die Berührungsfläche der Stromfäden des Elektrolyten mit der Elektrode wesentlich vergrößert, die Stromfäden ständig an die Elektrode hingeleitet und schließlich die Durchflußmenge des Elektrolyten so geregelt, daß keine unzersetzten Teile durch die Elekrode hindurchgelangen. Man verwendet z. B. Formstäbe, wie sie in den AbI). 1, 2, 3, 4 gekennzeichnet sind. Dabei bedeutet α das Diaphragma, b die Elektrode.A way has now been found to remedy these disadvantages, namely by using conductors shaped as electrodes, expediently made of metals such as iron, copper, ferro-manganese iron, silicon iron, alloys of these metals or of carbon, mixtures of carbon with concrete, etc., used, which have a great rigidity. Due to their suitably roof, dome or U-shaped shape, the contact surface of the electrolyte's current filaments with the electrode is significantly increased, the filaments of current are constantly directed to the electrode and, finally, the flow rate of the electrolyte is regulated so that no undecomposed parts pass through the electrode . One uses z. B. shape rods, as they are in the AbI). 1, 2, 3, 4 are marked. Α means the diaphragm, b the electrode. Eine bekannte Anordnung hat den Zweck, Ablagerungen auf den Membranen bzw. Kathodendecken und Gaspolster oberhalb der Kathoden zu vermeiden. Als Mittel dazu dient, daß die Membran, die die Kathode bedeckt, nach beiden Seiten steil abfällt. Der Querschnitt der stabförmigen Kathode ist also so gewählt, daß sie als Träger der Membran dieser eine nach oben verjüngte Form mit steilen Seitenwänden gibt. Ebenso sind ganz volle, netzartige oder nur teilweise netzartige Elektroden bekannt sowie Berieselungselektroden aus flachen Blechstreifen, die keine besondere Formstarrheit haben und auch durch ihre Form der Flüssigkeit keine besonders großen Oberflächen bieten.A known arrangement has the purpose of removing deposits on the membranes or Avoid cathode ceilings and gas cushions above the cathodes. As a means of doing this serves that the membrane that covers the cathode drops steeply on both sides. Of the The cross section of the rod-shaped cathode is therefore chosen so that it acts as a support for the membrane this gives an upwardly tapered shape with steep side walls. They are also completely full, reticulated or only partially reticulated Known electrodes as well as sprinkling electrodes made of flat sheet metal strips that have no particular dimensional rigidity and also Due to their shape of the liquid, they do not offer particularly large surfaces. Die vorliegende Erfindung betrifft etwas anderes und hat einen ganz anderen Zweck. Einerseits sollen die Stäbe dadurch, daß sie große Formstarrheit haben und sich nicht verziehen können, den gleichmäßigen Abstand zwischen den Elektroden und gegeneinander sichern und ferner die Zwischenräume zwischen den einzelnen Stäben so einstellbar sein, daß sie eine Regelung der Durchflußmengen gestatten.The present invention is directed to something else and has an entirely different purpose. On the one hand, the rods should have great dimensional rigidity and not warp can, the even distance between the electrodes and each other secure and furthermore the gaps between the individual rods can be adjusted so that they allow a regulation of the flow rates. Unter geformten Leitern sind nach vorliegender Erfindung Stäbe mit einem bestimmten Ouerprofil zu verstehen, zum Unterschied von bekannten kugel- oder trommeiförmigen Elektroden. Shaped conductors according to the present invention are bars with a certain To understand Ouerprofil, in contrast to known spherical or drum-shaped electrodes. 60 Pate ν τ-An s PRU cn: 60 Pate ν τ-An s PRU cn: Stabförmige Elektroden von großer Formstarrheit aus geformten Leitern, wie Metallen, Kohle u. dgl. in Dach-, Kuppel- g5 oder Γ ~Rod-shaped electrodes of great dimensional rigidity made of shaped conductors such as metals, carbon and the like in roof, dome g 5 or Γ ~
