Definitions

  • the invention relates to an anode made of insoluble metal with a support rod for the electrical extraction or electrodeposition of non-ferrous metals from solutions.
  • the gas is passed through a pipe system laid on the cell bottom (GB-PS 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 by supply lines from above (US Pat. No. 3,928,152, DE-OS 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.
  • anode of the type mentioned at the beginning which is designed according to the invention in such a way that the anode 1 on the lower edge has a width that extends over the width, in the case of gassing electrolysis for electrical extraction or galvanic deposition of non-ferrous metals
  • 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 supply of gas to the gas supply, in particular Air comes from a gas supply line in any way, for example by means of a hose connection.
  • a gas supply line in any way, 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 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. Between the rails of two adjacent anodes should be easy to enter and exit a gap of approx. 10 to 15 mm should be maintained.
  • 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 are inclined horizontally or upwards relative to the anode surface.
  • 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.
  • the pipe provided with gas outlet openings is expediently made of plastic, such as rigid PVC. This guarantees that incrustations and thus malfunctions, which can occur as a result of the entry of gas into 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 projects downward beyond the anode.
  • 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 anode 1 is provided with the support rod 2, which has a bore 5 at one end.
  • the bore 5 runs up to the outer edge line of the anode 1 in the axis of the support rod 2 and is then directed vertically downwards.
  • Both ends of the bore 5 are provided with soldered or screwed pipe nipples for receiving the quick coupling 8 on the one hand and for connecting the gas supply 9 on the other.
  • a tube 6 On the lower edge of the anode 1 there is a tube 6 provided with gas outlet openings 7, which is connected to the gas supply 9 via a push-in sleeve 10.
  • 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).
  • Fig. 2 also shows that the rails 4 serve as spacers, include the gas supply 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 along the length of 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.
