Description
Die Erfindung betrifft eine Anodenanordnung mit einer plattenförmigen Anode aus Ventilmetall mit aktiver Oberfläche für elektrolytische Prozesse, insbesondere für das Abscheiden von Metall aus Metallionen-enthaltender Lösung auf einer Unterlage, die mit einem Stromzuleiter aus Ventilmetall verbunden ist.The invention relates to an anode arrangement with a plate-shaped anode made of valve metal with an active surface for electrolytic processes, in particular for the deposition of metal from metal ion-containing solution on a base which is connected to a current feeder made of valve metal.
In elektrolytischen Prozessen, wie z. B. der Chloralkali-Elektrolyse, der elektrolytischen Verzinkung von Stahlbändern oder der Verchromung, müssen große Ströme bis zu 18.000 A/m² gleichmäßig über große Elektrodenflächen (bei der Stahlbandverzinkung bis zu 4 m2 und bei der Chloralkali-Industrie bis zu 36m2) verteilt werden. Diese Elektrodenflächen bestehen im Falle der Stahlbandverzinkung aus segmentierten Titanplatten, im Falle der Chloralkali-Industrie werden Drahtgitterstreckmetalle oder Flachprofile verwendet, die ebenfalls segmentiert sind.In electrolytic processes, such as. B. the chlor-alkali electrolysis, the electrolytic galvanizing of steel strips or the chrome plating, large currents up to 18,000 A / m² must be evenly distributed over large electrode areas (in the steel strip galvanizing up to 4 m 2 and in the chlor-alkali industry up to 36m 2 ) will. In the case of steel strip galvanizing, these electrode surfaces consist of segmented titanium plates, in the case of the chlor-alkali industry, wire mesh expanded metals or flat profiles are used, which are also segmented.
Der Strom wird dabei von außen über gut leitende Metalle, wie z. B. Kupfer, Aluminium oder Stahl in die Elektrolyse-Zelle eingespeist, wobei ein Kontakt zwischen diesen gut leitenden Metallen und dem Material der Anode, das in der Regel aus Titan besteht, hergestellt werden muß.The current is from the outside via highly conductive metals, such as. B. copper, aluminum or steel fed into the electrolysis cell, a contact between these highly conductive metals and the material of the anode, which usually consists of titanium, must be made.
Da sich Kupfer, Aluminium oder Stahl in den in der Praxis üblichen Elektrolyten unter anodischer Polarisation leicht auflösen, werden sie durch eine Schutzhülse aus Titan, die am eigentlichen Elektrodenkörper dicht befestigt ist und den Stromleiter bis nach außen führt, umschlossen.Since copper, aluminum or steel easily dissolve in the usual electrolytes under anodic polarization, they are enclosed by a protective sleeve made of titanium, which is tightly attached to the actual electrode body and leads the current conductor to the outside.
Eine solche Anordnung ist in der GB-OS 2 194 963 beschrieben. Dabei ist eine Titananode mit einem Stromzuleitungsbolzen aus Kupfer über ein das untere Ende des Bolzens hülsenartig umfassendes Anschlußelement aus Titan verbunden, wobei die eigentliche Fixierung zwischen dem Stromzuleitungsbolzen und dem hülsenartigen Anschlußelement durch Ausgießen mit Metall erzielt wird.Such an arrangement is described in GB-OS 2 194 963. In this case, a titanium anode is connected to a copper power supply pin via a titanium connecting element which surrounds the lower end of the pin in a sleeve-like manner, the actual fixation between the power supply pin and the sleeve-like connecting element being achieved by pouring out metal.
Die Erfindung stellt sich die Aufgabe, eine preiswerte und funktionssichere Stromversorgung einer Anode zu gewährleisten, wobei ein im Elektrolyten nichtbeständiger, jedoch elektrisch gut leitender Werkstoff für den Träger der Anode verwendet werden soll.The object of the invention is to ensure an inexpensive and functionally reliable power supply for an anode, wherein a material which is not stable in the electrolyte but is good electrical conductor should be used for the support of the anode.
Die Aufgabe wird durch die kennzeichnenden Merkmale des Anspruchs l gelöst.The object is achieved by the characterizing features of
In einer bevorzugten Ausführungsform wird als Werkstoff für den Kern des Trägers Stahl eingesetzt, während der den Träger umhüllende Mantel aus Titan besteht; der Mantel ist am Rand mit dem buchsenförmigen Teil des Stromzuleiters verschweißt. Der aus dem buchsenförmigen und dem hülsenförmigen Teil zusammengesetzte Stromzuleiter besteht aus Titan oder einer Titan-Basis-Legierung, wobei die im Betriebszustand aneinanderliegenden Kontaktflächen des hülsenförmigen und des buchsenförmigen Teils platiniert sind. Das hülsenförmige und das buchsenförmige Teil sind lösbar miteinander verbunden.In a preferred embodiment, steel is used as the material for the core of the carrier, while the sheath enveloping the carrier consists of titanium; the jacket is welded at the edge to the socket-shaped part of the power supply. The current feeder composed of the socket-shaped and the sleeve-shaped part consists of titanium or a titanium-based alloy, wherein the contact surfaces of the sleeve-shaped and the socket-shaped part, which abut one another in the operating state, are platinized. The sleeve-shaped and the sleeve-shaped part are detachably connected to one another.
In weiteren bevorzugten Ausführungsformen ist es möglich, als Werkstoff für den Kern des Trägers Kupfer oder Aluminium einzusetzen.In further preferred embodiments, it is possible to use copper or aluminum as the material for the core of the carrier.
Weitere vorteilhafte Ausgestaltungen der Erfindung sind den Unteransprüchen zu entnehmen.Further advantageous embodiments of the invention can be found in the subclaims.
Als vorteilhaft erweist sich eine preiswerte und sichere Stromverbindung zur Anode, wobei ein sparsamer Einsatz von Ventilmetall erfolgt; durch die lose Umkleidung werden aufwendige Arbeitsprozesse, wie z. B. Explosionsplattieren, vermieden, die zudem erhebliche Toleranzprobleme in der Ebene des Trägers nach sich ziehen, da in der Praxis eine Vielzahl von Stromzuleitern zwischen Träger und Anode bzw. Anoden eingesetzt werden muß; dabei erweist sich die Möglichkeit der direkten Einfräsung der öffnungen für die Aufnahme der buchsenförmigen Teile in den Kern des Trägers für die Planlage aller buchsenförmigen Teile in einer idealen Ebene mit geringer Toleranz als sehr vorteilhaft. So ist auf einer als Kern dienenden Platte mit einer Größe von 4 m2 und einer Dicke von 40 mm eine Toleranz der Planlage der buchsenförmigen Teile in der idealen Ebene von + 0,5 mm zu erzielen.An inexpensive and secure power connection to the anode has proven to be advantageous, with valve metal being used economically; due to the loose casing, complex work processes, such as B. explosion plating avoided, which also cause significant tolerance problems in the plane of the carrier, since in practice a large number of current conductors between the carrier and anode or anodes must be used; The possibility of direct milling of the openings for receiving the bush-shaped parts in the core of the carrier for the flatness of all bush-shaped parts in an ideal plane with low tolerance proves to be very advantageous. Thus, on a plate serving as a core with a size of 4 m 2 and a thickness of 40 mm, a tolerance of the flatness of the bush-shaped parts in the ideal plane of + 0.5 mm can be achieved.
Ein weiterer Vorteil ist darin zu sehen, daß sowohl Stromzuführung als auch mechanische Verbindung zwischen Träger und Anode optimal und preiswert gelöst sind.Another advantage is the fact that both the power supply and the mechanical connection between the carrier and the anode are optimally and inexpensively solved.

Gemäß Figur 1 ist eine als Teilausschnitt dargestellte, plattenförmige Anode 1 aus Titan an ihrer Rückseite 2 über einen Stromzuleiter 3 aus Titan mit einem ebenfalls im Teilausschnitt dargestellten Träger 4 verbunden, der einen plattenförmigen Kern 5 aus Stahl enthält, der von einem Mantel 14 umgeben ist. Der Stromzuleiter 3 besteht aus einem an der Anode 1 durch ringförmige Verschweißung befestigten hülsenförmigen Teil 6 aus Titan und einem in einer Öffnung 8 des Kerns 5 eingesetzten buchsenförmigen Teil 7, das mit dem Kern durch Befestigung mittels Stifte 9 unverrückbar verbunden ist; als Stifte 9 werden gemäß Figur 1 Senkschrauben eingesetzt. Das hülsenförmige Teil 6 liegt mit seiner parallel zur Plattenfläche der Anode 1 verlaufenden ebenen Kontaktfläche 11 an einer ebenfalls ebenen Kontaktfläche 12 des buchsenförmigen Teils 7 an, wobei beide Kontaktflächen 11, 12 eine platinierte Oberfläche aufweisen, um Spaltkorrosion zu vermeiden. Die platinierten Oberflächen dieser beiden Teile 6, 7 des Stromzuleiters 3 sind in Figur 2 näher dargestellt. Anhand dieser Figur ist erkennbar, daß das mit einer zentralen Gewindeausnehmung 16 versehene hülsenförmige Teil 6 an seiner Kontaktfläche 11 mit einer Platinbeschichtung versehen ist, deren Schichtstärke ca. 0,5 /um beträgt. Die gegenüberliegende Kontaktfläche 12 des buchsenförmigen Teils 7 ist ebenfalls mit einer Platinbeschichtung in Stärke von 0,5 /um versehen, wobei dieses buchsenförmige Teil 7 eine zentrale Bohrung zur Durchführung eines Befestigungselements in Form einer Senkschraube 10 aus Titan enthält, wie sie in Figur 1 dargestellt ist. Die Senkschraube 10 stellt durch Verschraubung in der Gewindeausnehmung 16 eine unverrückbare Verbindung zwischen dem hülsenförmigen Teil 6 und dem buchsenförmigen Teil 7 und damit eine unverrückbare Verbindung zwischen Anode 1 und Träger 4 her.According to FIG. 1, a plate-
Der Kern 5 des Trägers 4 ist gemäß Figur 1 von einem Mantel 14 aus Titanfolie lose umhüllt, der im Bereich des buchsenförmigen Teils 7 zwei sich gegenüberliegende Öffnungen aufweist, deren Ränder 15 jeweils mit dem buchsenförmigen Teil 7 an dessen Oberflächen durch Verschweißen gas- und flüssigkeitsdicht verbunden sind. Der Mantel 14 besteht aus einer ca. 1 mm starken Titanfolie. Die umlaufenden Schweißstellen sind mit Ziffer 17 bezeichnet.The
Gemäß Figur 3 ist es auch möglich, das hier mit Ziffer 7' bezeichnete buchsenförmige Teil als axialsymmetrisches Drehteil mit einem Gewinde 18 auszubilden, welches in eine entsprechende Gewindeausnehmung 19 im Kern 5 mit einem An-schlag 20 für den erweiterten Bereich 21 des buchsenförmigen Teils 7' eingeschraubt wird. Das hülsenförmige Teil 6 ist durch eine umlaufende Schweißverbindung mit der Rückseite 2 der Anode 1 fest verbunden. Die beiden aneinanderliegenden Kontaktflächen 11, 12 sind ebenso, wie anhand der Figuren 1 und 2 erläutert, mit einer platinierten Oberfläche versehen. Die in dieser Figur dargestellteAccording to FIG. 3, it is also possible to design the socket-shaped part denoted here by numeral 7 'as an axially symmetrical rotating part with a
Anordnung läßt eine besonders einfache Montage zu, da das buchsenförmige Teil 7' nur noch in den Kern 5 bis zum Anschlag einzuschrauben ist. Um einen optimalen Anpreßdruck des buchsenförmigen Teils 7' an den Anschlag 20 im Kern 5 zu erzielen, weist das buchsenförmige Teil 7' Vertiefungen 22 auf, in welche Nocken eines Greifwerkzeuges zum Festdrehen einsetzbar sind. Die mechanische Verbindung zwischen den beiden Teilen 6 und 7' des Stromzuleiters 3 erfolgt dabei - wie bereits anhand der Figur 1 erläutert - mittels einer Senkschraube 10 aus Titan, die nach Einsetzen und Festschrauben des buchsenförmigen Teiles 7' eingeführt und mit der Gewindeausnehmung 16 im hülsenförmigen Teil 6 fest verschraubt wird.The arrangement permits particularly simple assembly, since the socket-shaped part 7 'can only be screwed into the
Figur 4 zeigt schematisch einen Querschnitt durch eine Anodenanordnung, wobei die Anode 1 über mehrere jeweils aus dem hülsenförmigen Teil 6 und dem buchsenförmigen Teil 7 bestehende Stromzuleiter 3 mit dem Träger 4 verbunden ist. Eine solche plattenförmige Anode 1 weist beispielsweise eine Grundfläche von 0,2 bis 0,4 m2 und eine Dicke im Bereich von 2 bis 7 mm auf; sie wird über eine Vielzahl solcher Stromzuleiter mit dem Träger 4 elektrisch und mechanisch fest verbunden. Die Stromzuleiter können beispielsweise in mehreren zueinander parallelen Reihen angeordnet sein. Eine der Anode 1 benachbarte Anode 1' ist zwecks Vereinfachung der Darstellung nur bruchstückweise gezeigt. Der Anschluß der Stromversorgung an den Träger 4 erfolgt durch einen oder mehrere Stromzuführungsbolzen aus elektrisch gut leitendem Material, welche ebenfalls mit einem Titanmantel versehen sind. Die Dicke des plattenförmigen Trägers 4 liegt im Bereich von 20 bis 60 mm; sie ist so groß, daß der von außen punktförmig in den Träger eingespeiste Strom ohne nennenswerte Widerstandsverluste gleichmäßig verteilt wird; zudem weist die Platte eine genügende mechanische Stabilität auf, um die in der Regel aus mehreren Anoden bestehende Anodenfläche zu tragen.FIG. 4 schematically shows a cross section through an anode arrangement, the
