Description

Elektrischer Sammler mit alkalischem Elektrolyt. In elektrischen Sammlern mit alkalischem Elektrolyt, deren negative Platten aus flachen, senkrecht stehenden Taschen aus dünnem feingelochten Stahlblech bestehen, die mit Eisen oder Kadmium gefüllt sind, werden die. Elektroden in der Regel durch Hartgummistäbe voneinander isoliert, -:die in senkrechte, in die Platten eingepreßte Nuten geschoben werden. Um diese Stäbe in ihrer- Lage zu erhalten, muß der Plattensatz von Anfang an senkrecht zur Plattenebene etwas zusammengepreßt sein, was dadurch geschieht, daß das Elementgefäß dicht mit Platten nebst Isolatoren vollgebaut wird. Bestehen nun auch die positiven Elektroden aus ebensolchen Taschen, die mit Sauerstoffverbindungen des Nickels oder Kobalts gefüllt sind, so entstehen durch den engen, starren Einbau des Plattensatzes verschiedene Nachteile, da die positiven Taschen im Betrieb aufquellen. Sie füllen den Raum zwischen den Hartgummistäben aus, wodurch Kurzschluß entsteht, ferner üben sie einen starken Druck auf die Wände des Elementgefäßes aus, so daß der Plattensatz nicht mehr aus demselben herausgehoben werden kann, und endlich verursachen sie das Ausbauchen oder sogar das Reißen des Elementgefäßes. Diese Nachteile werden nach der Erfindung dadurch vermieden, daß der Plattensatz von einem Mantel aus Stahlblech o: dgl. umgeben wird, welcher in der zur Plattenebene senkrechten Richtung elastisch ist und in dieser Richtung das Elementgefäß nicht vollständig ausfüllt.Electrical collector with alkaline electrolyte. In electric collectors with alkaline electrolyte, the negative plates of which are flat, vertical Bags are made of thin finely perforated sheet steel, covered with iron or cadmium are filled, the. Electrodes usually separated by hard rubber rods insulated, -: which are pushed into vertical grooves pressed into the plates. In order to get these bars in their position, the set of plates must be vertical from the start be somewhat compressed to the plane of the plate, which happens because the element vessel is built tightly with plates and insulators. There are now also the positive ones Electrodes from such pockets, which are connected to nickel or oxygen compounds Cobalts are filled, so arise through the narrow, rigid installation of the plate set various disadvantages, as the positive pockets swell up during operation. You fill practice the space between the hard rubber rods, which causes a short circuit they exert a strong pressure on the walls of the element vessel, so that the plate set can no longer be extracted from it, and finally they cause bulging or even tearing of the element vessel. These disadvantages will be avoided according to the invention that the plate set of a jacket made of sheet steel o: the like. Which is elastic in the direction perpendicular to the plane of the plate and in this direction does not completely fill the element vessel.

Hierdurch werden dauernd die Isolatoren in ihrer Lage festgehalten, und die positiven Taschen können beliebig aufquellen, ohne Kurzschluß zu machen oder einen Druck auf die Gefäßwände auszuüben. Auch :die Entfernung des Mantels ist trotzdem ohne Schwierigkeit möglich.This permanently holds the isolators in their position, and the positive pockets can swell at will without making a short circuit or to exert pressure on the vessel walls. Also: the removal of the coat is still possible without difficulty.

Die Zeichnung zeigt einige Ausführungsformen des Sammlers nach der Erfindung. Abb. r ist ein wagerechter Schnitt durch denselben. a ist das Elementgefäß, b sind die negativen und c die positimen Elektroden, ddie Hartgummistäbe, e ist der Mantel aus Stahlblech. Seine zur Plattenebene senkrechten Seiten f sind gewellt, damit sie die Ausdehnung des Plattensatzes senkrecht zur Plattenebene gestatten, seine beiden anderen Seiten g können zwecks Versteifung mit beliebiger Prägung versehen sein.The drawing shows some embodiments of the collector according to the invention. Fig. R is a horizontal section through the same. a is the element vessel, b are the negative and c the positive electrodes, d the hard rubber rods, e is the sheet steel jacket. Its sides f, which are perpendicular to the plane of the plate, are corrugated so that they allow the set of plates to expand perpendicular to the plane of the plate;

Statt die Seite f des Mantels zu wellen, kann man sie mit Schlitzen versehen, wie die Abb. 2_ und 3 in Ansicht zeigen, und dadurch in ihrer Querrichtung elastisch machen. Nach Abb. 2 sind die kurzen Schlitze senkrecht und gegeneinander versetzt, wie dies beim sogenannten Streckmetall bekannt ist. Nach Abb. 3 liegen die langen Schlitze i im wesentlichen wagerecht und haben Wellenform, so däß die ebenfalls wellenförmigen Stege k bei durch in wagerechter Richtung erfolgendem Zug eine flachere Wellenform annehmen, wodurch das ganze Blech breiter wird. Statt der wellenförmigen Schlitze können selbstverständlich auch zickzackförmige angewandt werden.Instead of corrugating the side f of the jacket, it can be made with slits provided, as Fig. 2_ and 3 show in view, and thereby in their transverse direction make elastic. According to Fig. 2, the short slots are perpendicular and against each other offset, as is known from the so-called expanded metal. Lie according to Fig. 3 the long slots i are essentially horizontal and have a wave shape, so that the also wave-shaped webs k when taking place in the horizontal direction by train assume a flatter wave shape, making the whole sheet wider. Instead of the Wave-shaped slots can of course also be used in zigzag shapes will.
