Description
Herstellung der aktiven Masse für elektrische Sammler Die vorliegende Erfindung bezieht sich auf ein Verfahren zur Herstellung der aktiven Masse für elektrische Bleisammler, und zwar unter Verwendung von Bleischlamm, wie @er insbesondere bei Bleisammlern anfällt. Bisher war eine Wiederverwendung des aus etwa 6o bis 65% Bleisulfat rund Ptwa 3o bis 35 % Bleiperoxyd bestehenden Bleischlammes zur Herstellung der aktiven Masse nur auf Grund eines verhältnismäßig sehr umständlichen und auch kostspieligen Verfahrens möglich. Zu diesem Zweck -unterwarf man den Bleischlamm in einem Ofen einem Glühprozeß und unterzog das in dem Ofen erzeugte oxydhaltige Material einem sorgfältigen Zerkleinerungsprozeß. Hierauf wurde in üblicher Weise die nach diesem Verfahren erzeugte Glätte mit Schwefelsäure zu einer Paste verarbeitet.Manufacture of active mass for electrical collectors The present The invention relates to a method for producing the active composition for electrical Lead collector, using lead sludge, such as @er in particular at Lead collectors. So far, it has consisted of about 6o to 65% lead sulfate around Ptwa 3o to 35% lead peroxide existing lead sludge for the production of the active mass only because of a relatively very cumbersome and also costly Procedure possible. For this purpose the lead sludge was thrown into an oven an annealing process and subjected the oxide-containing material produced in the furnace to a careful crushing process. Then, in the usual way, the one after this Process produced smoothness with sulfuric acid processed into a paste.
Demgegenüber wird bei !dem Verfahren nach der vorliegenden Erfindung dadurch ein ganz besonderer technischer Fortschritt erzielt, daß Bleistaub und/oder reaktionsfähige Bleiverbindungen, denen bei Verwendung der aktiven Masse für negative Elektroden gegebenenfalls die üblichen Zusätze hinzugegeben sind, mit Bleischlamm, wie er insbesondere aus' in Betrieb befindlichen Bleisammlern mit ant'nnonfreien Elektrodenplatten -entnommen ist, in einer Mischvorrichtung innig gemischt werden. Während des Mischvorganges wird erforderlichenfalls so viel Wasser und/oder Schwefelsäure hinzugefügt, daß eine schmierfähige Paste entsteht. Es bleibt also jeglichezusätzlicheflitzebrehandlung des Bleischlamxneserspart, da schon allein durch die auftretende R@eakti:onswärmne die erforderliche Trocknung des Schlammes erzielt wird. Gleichzeitig findet eine chemische Umsetzung, nämlich eine Oxydbildung, statt. Hierdurch entsteht eine besonders hohe und durchaus 'erwünschte Porosität der Masse bei deren Formation. Die mit der aktiven Masse nach her vorliegenden Erfindung hergestellten Sammlerplatten zeichnen sich durch leine besonders hohe Kapazität und eine spezifisch hohe Belastbarkeit aus. Der Bleischlamm wird gegebenenfalls vor der Verwendung unter gleichzeitiger Entfernung etwa vorhandener Fremdkörper gewaschen.In contrast, the method according to the present invention thereby a very special technical progress achieved that lead dust and / or reactive lead compounds, which when using the active material for negative Electrodes where necessary the usual additives are added, with lead sludge, As he is in particular from 'in operation lead collectors with non'nnon-free Electrode plates -taken, are intimately mixed in a mixing device. If necessary, as much water and / or sulfuric acid is added during the mixing process added that a lubricious paste is formed. So there remains any additional flash treatment saves the lead schlamxneserser, because alone through the occurring reaction heat the required drying of the sludge is achieved. At the same time one finds chemical conversion, namely an oxide formation, takes place. This creates a special one high and quite 'desirable porosity of the mass during its formation. The one with the Active mass according to her present invention produced collector plates draw particularly high capacity and a specifically high load capacity the end. The lead sludge is optionally used prior to use with simultaneous Removal of any foreign bodies washed.
Auf Grund praktischer Versuche erzielt man besonders hochwertige aktive Massee mit @dein Verfahren nach der vorliegenden Erfindung, wenn man die reaktionsfähige Bleiverbindung und/oder den Bleistaub in gleichen Gewichtsmengen mit dem Bleischlamm mischt. Bei dem Mischvorgang wird die entstehende Reaktionswärme zur Verdampfung des in dem Bleischlamm enthaltenen überschüssigen Wassers benutzt. Während des Mischvorganges fügt man so viel zusätzliches Wasser und'o.der Schwefelsäure hinzu, daß die bei dem Mischvorgang entstehende Temperaturerhöhung in den zulässigen Grenzen bleibt. Durch das Hinzugeben von Wasser und;ioder Schwefelsäure wird auch der entstehenden Paste die ge-. wünschte Konsistenz gegeben und sie besonders schmierfähig gemacht.On the basis of practical experiments, particularly high-quality active ones can be achieved Massee with your method according to the present invention if you have the reactive Lead compound and / or the lead dust in equal amounts by weight with the lead sludge mixes. During the mixing process, the resulting heat of reaction is converted into evaporation of the excess water contained in the lead sludge. During the mixing process adds you add so much additional water and / or sulfuric acid, that the temperature increase occurring during the mixing process is within the permissible limits remain. By adding water and; i or sulfuric acid, the resulting Paste the ge. desired consistency and made it particularly lubricious.
