Embodiment Construction

[0013] figure 1 and 2 A device is shown for removing deposits 2, 3 that accumulate on the surface of an electrode such as a cathode 1 made of stainless steel during electrolysis. According to the figure, the cathode 1 is transported from electrolysis to a stripping station 17 , for example by means of a conveyor 12 . According to this example, the cathode is supported at the support structure 10 of the stripping station located near the suspension rod 11 , ie at that end of the cathode which is above the electrolytic solution during the electrorefining process. Furthermore, during the removal process, the cathode 1 is supported by support elements 6, 7, 8, 9 provided in the stripping station, such that the cathode is in a vertical position during the removal of the deposits. By means of the supporting elements, the cathode can be supported on both sides of the cathode, or only at desired points. In order to remove the accumulated deposits 2, 3 on both sides of the cathode 1...

Abstract

The invention relates to an equipment (4, 5) for removing deposits accumulated in electrolytic refining on the surface of an electrode, such as a cathode (1), said equipment including at least one element for stripping the deposits (2, 3) and at least one element for controlling the stripping element; said equipment includes at least one stripping element (13) that is turnably movable in the vertical direction of the cathode, and the cathode can be bent owing to the contact with said stripping element. The invention also relates to a method realized by said equipment.

Description

technical field [0001] The present invention relates to an apparatus and method for removing deposits resulting from electrorefining from the surface of an electrode, such as a cathode. Background technique [0002] In the production of many metals such as copper, zinc or nickel, a major step in the production process is electrolysis, in which the metal to be produced is deposited on the surface of an electrode, the cathode, by conduction of an electric current through the electrolyte. Typically, the cathode is an object provided with a suspension rod held above the surface of the electrolyte for suspending the cathode within the cell and for connecting it to an electrical circuit, and with a A plate-shaped component immersed in an electrolyte, the mother plate, on which the metal to be produced is deposited. [0003] In modern plants, where the cathode plates are usually made of a different metal than the metal to be produced, both vertical edges or all three edges of the ...
