Definitions
- the invention relates to an anode made of insoluble metal with a support rod for the electrolytic extraction or electrodeposition of non-ferrous metals from solutions.
- the gas is passed through a pipe system laid on the cell bottom (GB-A-1 392 705), the gassing pipes of which can also have a porous jacket to form a veil from fine gas bubbles (US Pat. No. 3,959 112), or via gassing pipes held by support elements on the cell bottom and supplied from above by supply lines (US-A-3 928 152, DE-A-25 08 094).
- the known gassing methods are disadvantageous insofar as complicated structural requirements have to be met and, in particular, the cleaning of the electrolysis cell, which is required from time to time, is made extremely difficult by the separate installation of the gassing elements.
- the object of the invention is to find a concept for the electrical extraction or galvanic deposition of non-ferrous metals, in which the advantages of fumigation electrolysis are retained, but the known, in particular the aforementioned disadvantages are avoided.
- an anode of the type mentioned at the outset is used in the fumigation electrolysis for the electrical extraction or galvanic deposition of non-ferrous metals, which is designed in accordance with the invention in such a way that the anode 1 has a width across the bottom edge with Gas outlet openings 7 provided, detachably attached tube 6 and a gas supply 9 connected to the anode and running over its long side and leading to the tube 6.
- the gas supply with gas is supplied from a gas supply line in any manner, for example by means of a hose connection.
- a gas supply line in any manner, for example by means of a hose connection.
- one side of the anode support rod is provided with a bore which has a connection at the inner bore end to the gas supply running over the longitudinal side of the anode and a connector at the outer bore end for connecting a gas supply line and, in a further preferred embodiment of the invention, the connector is designed as a quick coupling. All that is then required is an elastic connecting piece between the quick coupling and the gas supply line.
- an advantageous embodiment provides for this to be connected to the gas supply by means of a push-in sleeve.
- a further preferred embodiment of the invention consists in that non-conductive rails encompassing the longitudinal sides are arranged on the anode, one of which fixes the gas supply to the anode.
- the laterally extending rails can have holders for the tube and the extension of the rails perpendicular to the anode surface can be such that they serve as spacers to the adjacent cathode. Spacers in the sense meant here means that the minimum distance between the anode and cathode is avoided.
- the thickness of the entire rail i.e. after it has been extended on both sides, is approximately 25 to 30 mm. A gap of approx. 10 to 15 mm should be maintained between the rails of two adjacent anodes for easy insertion and removal of the cathodes.
- the position of the gas outlet bores in the horizontally running tube can be arbitrary for the gassing of the electrode spaces. A particularly effective gassing is achieved, however, if the axes of the gas outlet bores in the tube run horizontally or upwards relative to the anode surface.

- the pipe provided with gas outlet openings is expediently made of plastic, such as hard PVC. This ensures that incrustations and thus malfunctions, which can occur as a result of gas entering the crystallizable electrolyte in the region of the gas outlet openings, are avoided.
- the gas outlet openings have a diameter of the order of 0.8 mm. Their mutual distance is about 50 to 70 mm. Adequate fumigation can be achieved if the gas is supplied at an overpressure of 0.2 to 0.5 bar.
- the cathode When filling an electrolytic cell, care should be taken that the cathode protrudes downward beyond the anode. In order to avoid scattering in the area of the tube provided with gas outlet openings, the cathode should protrude so far that the escaping gas does not flow under the cathode. An extension of the cathode 20 to 30 mm below the line of the gas outlet openings is generally sufficient.
- the most important advantages achieved by the invention are that complicated cell installations or special cell constructions are not required, but that existing electrolysis cells can be converted without difficulty. Furthermore, operational handling and maintenance are economical and simple, and driving through the cell for the purposes of emptying, cleaning or repair is not hampered by complicated, fragile installation structures. If blockages occur, the pipe provided with gas outlet openings can be easily removed and, if necessary, replaced.
- the possible high specific current load of approximately 400 to 600 A / m 2 , the good cathode metal quality, the space-saving construction as well as good efficiency and simple operational handling together result in a decisive increase in the efficiency of the electrolysis. Furthermore, the distance setting of the cathodes when replacing them at the end of an operating period and that of the anodes without hindrance can be changed by a separate gassing construction.

- the tube 6 is additionally fixed by the holder 12.
- Two rails 4 are connected to the anode 1 by screw connections 13 (cf. in particular FIG. 2). 2 also shows that the rails 4 serve as spacers, include the gas feed 9 and electrically isolate the anode edges.
- the gas primarily air, - after saturation in a humidifier and heating to electrolyte temperature (not shown) - is supplied via the gas supply line 14, which is freely arranged lengthways to the electrolysis cell, the elastic connection 11 and the connector 8.
- the gas then passes through a gas feed line 9, which runs vertically downwards on the anode longitudinal edge, into the lower region of the anode to the plug-in sleeve 10 and from there into the tube 6. It exits into the electrolyte through the gas outlet openings.
- FIG. 3 shows in particular the ratio of the extension from cathode 3 to tube 6.

Description
Die Erfindung betrifft eine mit Tragestange versehene Anode aus unlöslichem Metall zur elektrolytischen Gewinnung oder galvanischen Abscheidung von NE-Metallen aus Lösungen.The invention relates to an anode made of insoluble metal with a support rod for the electrolytic extraction or electrodeposition of non-ferrous metals from solutions.
Insbesondere bei der elektrolytischen Gewinnung von NE-Metallen, die im allgemeinen mit Elektrolytlösungen mit relativ geringer NE-Metall-Konzentration erfolgt, ist es aus verfahrenstechnischen und wirtschaftlichen Gründen zweckmässig, den Elektrolyt in der Elektrolysezelle in Zirkulation zu versetzen. Durch den hierbei erzielten Konzentrationsausgleich wird eine NE-Metall-Verarmung im Kathodenbereich und eine Wasserstoffabscheidung, die wiederum zu verschlechterter Stromausbeute und zu schlechten inhomogenen NE-Metall-Abscheidungen führen, verhindert oder zumindest verringert.Particularly in the electrolytic extraction of non-ferrous metals, which is generally carried out with electrolyte solutions with a relatively low non-ferrous metal concentration, it is expedient for process engineering and economic reasons to circulate the electrolyte in the electrolytic cell. The concentration compensation achieved in this way prevents or at least reduces non-ferrous metal depletion in the cathode region and hydrogen deposition, which in turn leads to deteriorated current efficiency and poor inhomogeneous non-ferrous metal depositions.
Um die erforderliche Zirkulation herbeizuführen, ist es bekannt, in den Elektrolysezellen zu rühren, den Elektrolyt schnell durch die Elektrolysezelle strömen zu lassen oder an den Elektroden eine Gasspülung vorzusehen (vgl. «Ullmanns Encyklopädie der technischen Chemie», 4. Auflage, Band 3, Seite 268; V. Tafel «Lehrbuch der Metallhüttenkunde» Band 1 (1951), Seite 552; «Die technische Elektrometallurgie wässriger Lösungen», I. Teil, Akademische Verlagsgesellschaft Geest & Portig K.-G., Leipzig, 1961, Seite 129). Rühren und schnelles Durchströmen der Elektrolysezelle sind insofern wenig wirksame Massnahmen, als gerade an den entscheidenden Stellen, nämlich zwischen den Elektroden, die Turbulenz gering ist. Insoweit ist die Gasspülung, die zwischen den Elektroden vorgenommen werden kann, wirksamer.In order to bring about the necessary circulation, it is known to stir in the electrolysis cells, to let the electrolyte flow quickly through the electrolysis cell or to provide a gas purge on the electrodes (cf. “Ullmanns Encyklopadie der Technische Chemie”, 4th edition,
Bei den bisher bekannten Verfahren wird das Gas über ein am Zellenboden verlegtes Rohrsystem (GB-A-1 392 705), dessen Begasungsrohre zudem zur Bildung eines Schleiers aus feinen Gasblasen auch einen porösen Mantel aufweisen können (US-A-3 959 112), oder über von Tragelementen am Zellenboden gehaltene und mittels Zuführungsleitungen von oben versorgte Begasungsrohre (US-A-3 928 152, DE-A-25 08 094) zugeleitet.In the previously known processes, the gas is passed through a pipe system laid on the cell bottom (GB-A-1 392 705), the gassing pipes of which can also have a porous jacket to form a veil from fine gas bubbles (US Pat. No. 3,959 112), or via gassing pipes held by support elements on the cell bottom and supplied from above by supply lines (US-A-3 928 152, DE-A-25 08 094).
Obgleich von der Wirkung von Vorteil, sind die bekannten Begasungsverfahren insofern nachteilig, als komplizierte konstruktive Erfordernisse erfüllt sein müssen und insbesondere durch die separate Installation der Begasungselemente die von Zeit zu Zeit erforderliche Reinigung der Elektrolysezelle stark erschwert ist.Although advantageous from the point of view, the known gassing methods are disadvantageous insofar as complicated structural requirements have to be met and, in particular, the cleaning of the electrolysis cell, which is required from time to time, is made extremely difficult by the separate installation of the gassing elements.
Aufgabe der Erfindung ist, eine Konzeption bei der Elektrogewinnung oder galvanischen Abscheidung von NE-Metallen zu finden, bei der zwar die Vorteile des Begasungselektrolyse erhalten bleiben, jedoch die bekannten, insbesondere vorgenannten Nachteile vermieden werden.The object of the invention is to find a concept for the electrical extraction or galvanic deposition of non-ferrous metals, in which the advantages of fumigation electrolysis are retained, but the known, in particular the aforementioned disadvantages are avoided.
Die Aufgabe wird gelöst, indem bei der Begasungselektrolyse zur Elektrogewinnung oder galvanischen Abscheidung von NE-Metallen eine Anode der eingangs genannten Art eingesetzt wird, die entsprechend der Erfindung derart ausgestaltet ist, dass die Anode 1 an der Unterkante ein sich über die Breite erstreckendes, mit Gasaustrittsöffnungen 7 versehenes, lösbar angebrachtes Rohr 6 und eine mit der Anode verbundene, über ihre Längsseite verlaufende, zum Rohr 6 führende Gaszuführung 9 aufweist.The object is achieved in that an anode of the type mentioned at the outset is used in the fumigation electrolysis for the electrical extraction or galvanic deposition of non-ferrous metals, which is designed in accordance with the invention in such a way that the
Die Versorgung der Gaszuführung mit Gas, insbesondere Luft, erfolgt von einer Gasversorgungsleitung auf beliebige Weise, beispielsweise mittels einer Schlauchverbindung. Besonders vorteilhaft ist es jedoch, wenn eine Seite der Anodentragestange mit einer Bohrung versehen ist, die am inneren Bohrungsende eine Verbindung zur über die Anodenlängsseite verlaufenden Gaszuführung und am äusseren Bohrungsende ein Verbindungsstück zum Anschluss einer Gasversorgungsleitung aufweist und, in einer weiteren vorzugsweisen Ausgestaltung der Erfindung, das Verbindungsstück als Schnellkupplung ausgebildet ist. Es bedarf dann lediglich eines elastischen Verbindungsstückes zwischen Schnellkupplung und Gasversorgungsleitung.The gas supply with gas, in particular air, is supplied from a gas supply line in any manner, for example by means of a hose connection. However, it is particularly advantageous if one side of the anode support rod is provided with a bore which has a connection at the inner bore end to the gas supply running over the longitudinal side of the anode and a connector at the outer bore end for connecting a gas supply line and, in a further preferred embodiment of the invention, the connector is designed as a quick coupling. All that is then required is an elastic connecting piece between the quick coupling and the gas supply line.
Um das an der Unterseite der Anode angebrachte Rohr möglichst einfach lösen und wieder befestigen zu können, sieht eine vorteilhafte Ausgestaltung vor, dieses mittels einer Steckmuffe mit der Gaszuführung zu verbinden.In order to be able to detach and fasten the tube attached to the underside of the anode as simply as possible, an advantageous embodiment provides for this to be connected to the gas supply by means of a push-in sleeve.
Damit ein mechanischer Kontakt zwischen Anode und benachbarter Kathode vermieden wird, besteht eine weitere bevorzugte Ausführungsform der Erfindung darin, dass an der Anode deren Längsseiten umgreifende, nichtleitende Schienen angeordnet sind, deren eine die Gaszuführung an der Anode fixiert. Hierbei können - gemäss weiterer zweckmässiger Ausgestaltungen - die seitlich verlaufenden Schienen Halterungen für das Rohr aufweisen und die Erstreckung der Schienen senkrecht zur Anodenfläche derartig bemessen sein, dass sie als Abstandshalter zur benachbarten Kathode dienen. Abstandshalter im hier gemeinten Sinn heisst, dass das Unterschreiten eines Mindestabstandes zwischen Anode und Kathode vermieden wird. Es ist hingegen nicht erforderlich, dass beim Betrieb der Elektrolysezelle die Kathode an der Schiene anliegt. Die Dicke der gesamten Schiene, also nach beidseitiger Erstreckung, beträgt etwa 25 bis 30 mm. Zwischen den Schienen zweier benachbarter Anoden sollte zum einfachen Ein- und Ausfahren der Kathoden ein Spalt von ca. 10 bis 15 mm aufrechterhalten bleiben.In order to avoid mechanical contact between the anode and the adjacent cathode, a further preferred embodiment of the invention consists in that non-conductive rails encompassing the longitudinal sides are arranged on the anode, one of which fixes the gas supply to the anode. According to further expedient configurations, the laterally extending rails can have holders for the tube and the extension of the rails perpendicular to the anode surface can be such that they serve as spacers to the adjacent cathode. Spacers in the sense meant here means that the minimum distance between the anode and cathode is avoided. However, it is not necessary for the cathode to rest against the rail when the electrolysis cell is in operation. The thickness of the entire rail, i.e. after it has been extended on both sides, is approximately 25 to 30 mm. A gap of approx. 10 to 15 mm should be maintained between the rails of two adjacent anodes for easy insertion and removal of the cathodes.
Zur Begasung der Elektrodenräume kann die Lage der Gasaustrittsbohrungen im horizontal verlaufenden Rohr beliebig sein. Eine besonders wirksame Begasung wird jedoch erzielt, wenn die Achsen der Gasaustrittsbohrungen im Rohr gegenüber der Anodenfläche horizontal oder aufwärts geneigt verlaufen.The position of the gas outlet bores in the horizontally running tube can be arbitrary for the gassing of the electrode spaces. A particularly effective gassing is achieved, however, if the axes of the gas outlet bores in the tube run horizontally or upwards relative to the anode surface.
Damit das Einbringen der Kathoden in die mit Anoden bereits besetzte Elektrolysezelle bzw. der Austausch einzelner Anoden selbst in einfacher Weise durchführbar ist, empfiehlt es sich, die die Anoden umgreifenden Schienen oben und unten anzuschärfen.Thus the introduction of the cathodes into the electrolytic cell or the one already occupied with anodes If individual anodes can be replaced in a simple manner, it is advisable to sharpen the rails surrounding the anodes at the top and bottom.
Die über die Längsseite der Anode verlaufende Gaszuführung besteht vornehmlich aus einem Rohr des gleichen Werkstoffs wie die Anode. Gleiches gilt für die Steckmuffe zur Aufnahme des mit Gasaustrittsöffnungen versehenen Rohres. Die Gaszuführung wird fest, zweckmässigerweise durch Schweissen, mit der Anode verbunden.The gas supply running over the long side of the anode consists primarily of a tube of the same material as the anode. The same applies to the push-in socket for receiving the pipe provided with gas outlet openings. The gas supply is firmly connected to the anode, expediently by welding.
Das mit Gasaustrittsöffnungen versehene Rohr wird zweckmässigerweise aus Kunststoff, wie Hart-PVC, hergestellt Hierbei ist Gewähr dafür geboten, dass Inkrustationen und damit Störungen, die infolge des Eintretens von Gas in den kristallisierfähigen Elektrolyt im Bereich der Gasaustrittsöffnungen entstehen können, vermieden werden.The pipe provided with gas outlet openings is expediently made of plastic, such as hard PVC. This ensures that incrustations and thus malfunctions, which can occur as a result of gas entering the crystallizable electrolyte in the region of the gas outlet openings, are avoided.
Die Gasaustrittsöffnungen besitzen einen Durchmesser in der Grössenordnung von 0,8 mm. Ihr gegenseitiger Abstand beträgt etwa 50 bis 70 mm. Eine ausreichende Begasung lässt sich erzielen, wenn das Gas mit einem Überdruck von 0,2 bis 0,5 bar zugeführt wird.The gas outlet openings have a diameter of the order of 0.8 mm. Their mutual distance is about 50 to 70 mm. Adequate fumigation can be achieved if the gas is supplied at an overpressure of 0.2 to 0.5 bar.
Beim Besetzen einer Elektrolysezelle sollte darauf geachtet werden, dass die Kathode nach unten über die Anode hinausragt. Um eine Streuung im Bereich des mit Gasaustrittsöffnungen versehenen Rohres zu vermeiden, sollte die Kathode so weit hinausragen, dass das austretende Gas die Kathode nicht unterströmt. Eine Verlängerung der Kathode um 20 bis 30 mm unter die Linie der Gasaustrittsöffnungen ist im allgemeinen ausreichend.When filling an electrolytic cell, care should be taken that the cathode protrudes downward beyond the anode. In order to avoid scattering in the area of the tube provided with gas outlet openings, the cathode should protrude so far that the escaping gas does not flow under the cathode. An extension of the cathode 20 to 30 mm below the line of the gas outlet openings is generally sufficient.
Es empfiehlt sich, dass der Elektrolysezelle zuzuführende Gas, am zweckmässigsten vor dem Einleiten in die Gasversorgungsleitung, auf Elektrolyttemperatur vorzuwärmen und mit Wasserdampf weitgehend zu sättigen. Hierdurch wird die Gefahr einer Kristallisation von im Elektrolyt gelösten Bestandteilen in der Nähe der Gasaustrittsöffnungen weitgehend ausgeschlossen.It is advisable to preheat the gas to be supplied to the electrolysis cell, most suitably before introducing it into the gas supply line, to the electrolyte temperature and to saturate it largely with water vapor. This largely eliminates the risk of crystallization of constituents dissolved in the electrolyte in the vicinity of the gas outlet openings.
Die wesentlichsten mit der Erfindung erzielten Vorteile bestehen darin, dass komplizierte Zelleneinbauten oder spezielle Zellenkonstruktionen nicht erforderlich sind, sondern vorhandene Elektrolysezellen ohne Schwierigkeiten umgerüstet werden können. Weiterhin sind die betriebliche Handhabung sowie Instandhaltung wirtschaftlich und einfach und ist das Befahren der Zelle zu Zwecken der Entleerung, Reinigung oder Instandsetzung nicht durch komplizierte, bruchempfindliche Einbaukonstruktionen behindert. Beim Auftreten von Verstopfungen ist das mit Gasaustrittsöffnungen versehene Rohr leicht demontierbar und gegebenenfalls auswechselbar. Die mögliche hohe spezifische Strombelastung von etwa 400 bis 600 A/m2, die gute Kathodenmetallqualität, die raumsparende Konstruktion sowie guter Wirkungsgrad und einfache betriebliche Handhabung ergeben zusammen eine entscheidende Steigerung der Wirtschaftlichkeit der Elektrolyse. Ferner ist die Abstandseinstellung der Kathoden bei der Neubesetzung am Ende einer Betriebsperiode und die der Anoden ohne Behinderung durch eine separate Begasungskonstruktion veränderbar.The most important advantages achieved by the invention are that complicated cell installations or special cell constructions are not required, but that existing electrolysis cells can be converted without difficulty. Furthermore, operational handling and maintenance are economical and simple, and driving through the cell for the purposes of emptying, cleaning or repair is not hampered by complicated, fragile installation structures. If blockages occur, the pipe provided with gas outlet openings can be easily removed and, if necessary, replaced. The possible high specific current load of approximately 400 to 600 A / m 2 , the good cathode metal quality, the space-saving construction as well as good efficiency and simple operational handling together result in a decisive increase in the efficiency of the electrolysis. Furthermore, the distance setting of the cathodes when replacing them at the end of an operating period and that of the anodes without hindrance can be changed by a separate gassing construction.
