ABSTRACT:
The present invention relates to a device for tanks of circular type, such as for example thickeners, sludge tanks, mixing tanks and the like, in which at least one scraper arm, mixing arm or the like is journalled, as well as mounted in the center of the tank so as to be raisable and lowerable, and in which there are drive means capable of imparting a sweeping motion to the arm and its scrapers over the bottom of the tank. According to the invention an element is arranged extending between the periphery of the tank and its center, which element is longitudinally movable in relation to the periphery of the tank and is sufficiently rigid to be capable of transferring active or reactive forces to an extent at least corresponding to the torque of the scraper-carrying arm or the like.
