Abstract:
A toroidal vortex debris collection system comprising:an outer tube; an inner tube disposed coaxially within said outer tube, wherein the gap between said inner tube and said outer tube forms an annular duct; an inner fairing located at a distal end of said inner tube; at least one impeller located at a proximal end of said inner tube; a collector coupled to said impeller; and at least one screw compactor located within said collector; wherein said impeller causes a fluid flow through said system, said fluid flow flowing from said outer tube to said inner tube guided by said inner fairing, thereby being shaped substantially as a toroidal vortex capable of attracting debris from a region proximal to said toroidal vortex into said fluid flow; and wherein said fluid flow is rotated into a cylindrical vortex by said impeller, said cylindrical vortex ejecting said debris therefrom into said collector.
