Abstract
A device for providing the edge of a starting sheet of an electrode used in the electrolytic refining or recovery of metals with a dielectric part comprises a die space, in which the edge of the starting sheet of the electrode can at least partly be fitted, and a feeding device of the dielectric material for feeding the dielectric material into the die space. The device comprises changing members of the volume of the die space for pressing the dielectric material in the die space to that edge of the starting sheet of the electrode, which is at least partly fitted in the die space.
Claims25
A method of providing the edge (4) of the starting sheet (2) of an electrode used in the electrolytic refining or recovery of metals with a dielectric strip (5) that consists of dielectric material, comprising:
- using equipment (6) that comprises a die space (7) and a feeding device (8) of the dielectric material for feeding the dielectric material (14) into the die space (7),
- whereby the method comprises
- a positioning stage, at which the edge (4) of the starting sheet (2) of the electrode is at least partly fitted in the die space (7);
- a feeding stage, at which the dielectric material (14) that constitutes the dielectric strip (5) is fed into the die space (7);
- a melting stage, at which the dielectric material (14) that constitutes the dielectric strip (5) is melted;
- and
- a solidification stage, at which the dielectric material (14) that constitutes the dielectric strip (5) is allowed to solidify in the die space (7) for providing that edge (4) of the starting sheet (2) of the electrode, which is at least partly fitted in the die space (7), with the dielectric strip (5);
- characterized in that
- the dielectric material (14) in the die space (7), constituting the dielectric strip (5), is pressed to that edge (4) of the starting sheet (2) of the electrode which at least partly lies in the die space (7) during the solidification stage.
Equipment for providing the edge (4) of the starting sheet (2) of the electrode used in the electrolytic refining of recovery of metals with a dielectric strip (5) that consists of dielectric material, the equipment (6) comprising:
- melting equipment (15) for melting the dielectric material (14);
- a die space (7), in which the edge (4) of the starting sheet (2) of the electrode can at least partly be fitted and where the dielectric material (14) melted by the melting equipment (15) is adapted to solidify to form the dielectric strip (5);
- and
- a feeding device (8) of the dielectric material for feeding the dielectric material (14) into the die space (7);
- characterized in that
- the equipment (6) comprises pressing members (16) for pressing the dielectric material (14) in the die space (7) to that edge (4) of the starting sheet (2) of the electrode, which is at least partly fitted in the die space (7), during the solidification of the dielectric material (14) melted by the melting equipment (15).
