Abstract
The invention relates to a device for at least partly removing a deposit created in the electrolytic refining or electrowinning of metal from the surface of the mother plate used as an electrode in the refining or electrowinning process, said device comprising at least one member for removing the deposit and at least one member for controlling the removal member with respect to the deposit to be removed. According to the invention, the device comprises at least one gripping element that is used for creating a mechanical contact between the deposit and the removal member, said gripping element being connected to a control member, to which there are coupled both the shaft part of the gripping element and the deposit removal member.

A device for at least partly removing a deposit created in electrolytic refining or electrowinning from the surface of the mother plate used as an electrode in the refining or electrowinning process, said device comprising at least one member for removing the deposit and at least one member for controlling the removal member with respect to the deposit, characterized in that the device comprises at least one gripping element that is used for creating a mechanical contact between the deposit and the removal member, said gripping element being connected to a control member, to which there are coupled both the shaft part of the gripping element and the deposit removal member.
Apparatus for processing a mother plate used as an electrode in an electrolytic refining or electrowinning operation, the mother plate having a deposit on a surface thereof, said apparatus comprising:
- a means for securing the mother plate in a predetermined position,
- a control member,
- at least one gripping element that is attached to the control member and includes an engagement formation for physically engaging the deposit,
- a first displacement means coupled to the control member for displacing the control member towards and away from a location in which the engagement formation is positioned for physically engaging the deposit, and
- a second displacement means coupled to the control member for forcing the engagement formation into physical engagement with the deposit when the control member is in said location for thereby creating a mechanical connection between the deposit and the control member,
- and wherein the first displacement means is operative when the engagement formation has been forced into physical engagement with the deposit for displacing the control member away from said location and thereby at least partially removing the deposit from the mother plate.
A method of processing a mother plate used as an electrode in an electrolytic refining or electrowinning operation, the mother plate having a deposit on a surface thereof, said method comprising:
- securing the mother plate in a predetermined position,
- displacing a gripping element towards the mother plate so that an engagement formation of the gripping element is positioned for physically engaging the deposit,
- displacing the gripping element in a manner such as to force the engagement formation into physical engagement with the deposit, and
- displacing the gripping element away from the mother plate so that the deposit is at least partially removed from the mother plate.
