Abstract:
1. An ore filter having: a sub-frame comprising an array of frame members; a plurality of juxtaposed filter elements mounted to said sub-frame in a circular array along a horizontal plane; each of said filter elements having a sector-like shape, a perforated upper surface, and a piece of filtering material laid over and singly covering said perforated upper surface; said plurality of juxtaposed filter elements comprising pairs of juxtaposed filter elements; each of said pairs of juxtaposed filter elements having a pair of bordering sides and a space between said bordering sides; each of said bordering sides having a flat flange; and said flat flanges in said pair of bordering sides extending horizontally in a same plane toward each other in said space; said flat flanges in said pair of bordering sides being laid flat side-by-side upon one of said frame members in said array of frame members; each of said bordering sides having a lip extending between said perforated upper surface on a respective one of said filter elements in said pair of juxtaposed filter elements, and said flat flange on said bordering side in said respective one of said filter elements in said pair of juxtaposed filter elements; said lip extending downwardly and defining a depth of said respective one of said filter elements in said pair of juxtaposed filter elements; said lips and said flat flanges on said pair of bordering sides defining a pair of facing right-angle grooves in said space; a rectangular flat bar laid in said space and in said pair of facing right-angle grooves over said pieces of filtering material on said filter elements in said pair of juxtaposed filter elements; and a plurality of spaced bolts extending vertically through said rectangular flat bar and through said one of said frame members for clamping said rectangular flat bar, said pair of bordering sides and said pieces of filtering material on said filter elements in said pair of juxtaposed filter elements to said one of said frame members; said pieces of filtering material on said filter elements in said pair of juxtaposed filter elements comprising a first and second pieces of filtering material; each of said first and second pieces of filtering material having a first position extending diagonally across a respective one of said right-angle grooves like a string on a bow, and a second position laying against said lip and said flat flange in a respective one of said right-angle grooves; said first position of said first piece of filtering material being a mirror image of said first position of said second piece of filtering material; and said second position on said first piece of filtering material being a mirror and simultaneous image of said second position of said second piece of filtering material, said first and second positions being associated with a pre-mounting and a mounting of said bolts through said one of said frame members, respectively; and said first and second positions being associated with less and more tension, respectively in said first and second pieces of filtering material over said perforated upper surfaces of said filter elements in said pair of juxtaposed filter elements.
