KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Vorliegende Erfindung bezieht sich auf galvanische Beutelelemente und bezweckt, neben Erhöhung der Stromstärke durch Vergrößerung der Oberfläche der Lösungselektroden den inneren Widerstand des Elementes möglichst zu verringern.The present invention relates to galvanic bag elements and aims to in addition to increasing the current strength by increasing the surface area of the solution electrodes to reduce the internal resistance of the element as much as possible.
Dies wird dadurch erreicht, daß die Lösungselektrode (negative Polelektrode) aus die Ableitung aufnehmender Metallwolle oder Metallfasern in lockerem Zustand besteht und sich an die positive Polelektrode unmittelbar anlegt, welche aus Kohle besteht und in an sich bekannter Weise mit einem von einer porösen Hülle zusammengehaltenen gepulverten oder gekörnten Depolarisationsmittel umgeben ist.This is achieved in that the solution electrode (negative pole electrode) from the derivation absorbing metal wool or metal fibers is in a loose state and is in direct contact with the positive pole electrode, which consists of coal and in a known manner with one of a porous shell, powdered or granular depolarizing agent held together is surrounded.
Ein Ausführungsbeispiel der Erfindung an einem Zinkkohleelement ist durch die Zeichnung im senkrechten Schnitt wiedergegeben.An embodiment of the invention on a zinc carbon element is shown in the drawing reproduced in vertical section.
Das Element befindet sich in einem der hierfür gebräuchlichen Gefäße a. In der Mitte ist ein Kohlestab b eingesetzt, der an seinem oberen Ende eine Klemmschraube d trägt. Der Kohlestab ist mit pulverisiertem Braunstein umgeben; das Ganze hüllt ein Beutel f aus Leinwand o., dgl. ein. Der Raum außerhalb des Braunsteinbeutels ist mit Zinkwolle oder sonstigem fein zerteilten, aber locker zusammenliegenden Zink ausgefüllt. In die Zinkwolle ist ein Ring g aus Zink eingebettet, an den sich ein weiterer Zinkstreifen/? als Ableiter anschließt. Letzterer trägt außerhalb desElementgefäßes die Klemmschraube k. Das Element wird mit einer Salzlösung gefüllt, die bei ihrer Zersetzung eine lösbare Zinkverbindung ergibt, so daß die Zinkwolle dauernd blank bleibt.The element is in one of the vessels commonly used for this purpose a. In the middle a carbon rod b is inserted, which carries a clamping screw d at its upper end. The carbon rod is surrounded with powdered brownstone; the whole thing is wrapped in a bag f made of canvas or the like. The space outside the brown stone bag is filled with zinc wool or other finely divided but loosely packed zinc. In the zinc wool one ring is embedded g of zinc, followed by a further zinc strip /? connected as arrester. The latter carries the clamping screw k outside the element vessel. The element is filled with a salt solution which, when decomposed, produces a detachable zinc compound so that the zinc wool remains permanently bright.
Das Element kann durch eine isolierende Masse m oben verschlossen werden, welche ein Austrocknen der Flüssigkeit nach Möglichkeit verhindert und Stromübergang von Klemme zu Klemme ausschließt. Die sich während der Arbeit entwickelnden Gase entweichen durch ein Röhrchen η, durch das auch Flüssigkeit, wenn nötig, nachgefüllt werden kann.The element can be closed at the top by an insulating compound m , which prevents the liquid from drying out as far as possible and excludes current transfer from terminal to terminal. The gases that develop during the work escape through a tube η, through which liquid can also be refilled if necessary.
