Abstract
An arrangement for cleaning the bottom of an electrolytic tank of solids settled on the bottom of the tank, said arrangement comprising elements to be moved along the bottom or at least in the vicinity thereof in order to detach solids from the bottom. The arrangement comprises at least one moveable suction element, whereby at least part of the solids accumulated on the bottom is conducted out of the tank.
Claims19
An electrolytic apparatus comprising:
- an electrolytic tank having a bottom, and
- an arrangement for removing solids that have settled on the bottom of the electrolytic tank, said arrangement comprising an elongate suction element disposed in the tank close to the bottom of the tank and extending substantially parallel to the bottom of the tank, and a drive means for moving the suction element over the bottom of the tank in a direction transverse to the length of the suction element.
An electrolytic apparatus comprising:
- an electrolytic tank having a bottom, and
- an arrangement for removing solids that have settled on the bottom of the electrolytic tank, said arrangement comprising a hollow elongate suction element disposed in the tank close to the bottom of the tank and extending substantially parallel to the bottom of the tank, the suction element having a wall that defines an interior space and is formed with at least one aperture, a means for applying suction to the interior space of the suction element, and a drive means for moving the suction element over the bottom of the tank in a direction transverse to the length of the suction element.
A method of operating an electrolytic apparatus that includes an electrolytic tank having a bottom, said method comprising removing solids that have settled on the bottom of the electrolytic tank by:
- placing a hollow elongate suction element in the tank so that the suction element is close to the bottom of the tank and extends substantially parallel to the bottom of the tank, the suction element having a wall that defines an interior space and is formed with at least one aperture,
- applying suction to the interior space of the suction element, and
- moving the suction element over the bottom of the tank in a direction transverse to the length dimension of the suction element.
