Abstract

Improvements in the construction of filtering devices, comprising a cylindrical fluid-tight container, a series of filter elements located on a central axis coaxial with said cylindrical container, said central axis being hollow and being designed to rotate by the action of any means appropriate, characterized in that the said filter elements are constituted by two filtering walls, a semirigid inner frame that supports said filtering walls of each filter element, a central ring and threaded in said hollow central axis and attached to said frame, being in communication said central ring with openings arranged along the entire length of said central axis, one of the two filtering walls having a plurality of baffle devices angularly separated from one another obliquely relative to the radii of the filter elements and leaving the outer surface of the same, so that when the hollow central axis rotates, therefore driving all the filter elements for the cleaning operation, the deflecting devices effect, on the part of the filter elements that rotate in the liquid, on the one hand a deviation of the liquid in the direction of the central part of the filter elements and on the other hand a flexing of said filter elements in a zone comprised between the lower end of the deflectors and the central ring of said filter elements.
