Abstract

Abstract A fluid separator for separating solids from a liquid or separating a heavier substance from a lighter substance in either liquids or gases by means of centrifugal force in conjunction with the eddy current principle comprising a housing or jacket containing a spirally formed fluid conduit for rotation within said housing adapted to convey fluid therethrough. The coils of the conduit are internally formed with a multiple of spaced abutments on the inside or the outside of the conduit, or both, the abutments extending into the path of the fluid, and openings are provided in the conduit adjacent each of the abutments to permit a selected substance to exit from the conduit due to forces created by the rotating spiral conduit which tends to flow a lighter substance inwardly and a heavier substance outwardly to the wall of the conduit. The abutments in the conduit extending into the path of the fluid set up eddy currents in the spinning liquid to spin adjacent the leading edge of the abutments in one direction and around the trailing edge of the abutments in the reverse direction collecting the lighter or heavier substances disposed in the fluid which are then forced out through the apertures adjacent said abutments. A wall is provided in the jacket to keep lighter and heavier substances separate. Intermediate substances may continue to flow through the conduit.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 161 words
In an eddy current principle fluid separator adapted to separate contaminants from a moving fluid, the improvement comprising: a housing, a coiled fluid conduit extending through said housing, means provided in said conduit comprising a plurality of spaced abutments extending from the internal surface of said conduit internally thereof into the path of said moving fluid on the inside and outside of said coiled conduit relative to the axis thereof causing the creation of eddy currents adjacent to the edges of said abutments, opening means in said conduit including inside openings and outside openings respectively adjacent to said abutments to eject contaminants from said fluid outwardly of said conduit by means of the eddy current effect around said abutments, and hollow wall means in said housing partially embedding said conduit but leaving said inside openings communicating with the inside of said wall means and said outside openings communicating with the outside of said wall means for separating lighter and heavier substances.
Claim 2
Dependent Claim 161 words
In an eddy current principle fluid separator adapted to separate contaminants from a moving fluid, the improvement comprising: a housing, a coiled fluid conduit extending through said housing, means provided in said conduit comprising a plurality of spaced abutments extending from the internal surface of said conduit internally thereof into the path of said moving fluid on the inside and outside of said coiled conduit relative to the axis thereof causing the creation of eddy currents adjacent to the edges of said abutments, opening means in said conduit including inside openings and outside openings respectively adjacent to said abutments to eject contaminants from said fluid outwardly of said conduit by means of the eddy current effect around said abutments, and hollow wall means in said housing partially embedding said conduit but leaving said inside openings communicating with the inside of said wall means and said outside openings communicating with the outside of said wall means for separating lighter and heavier substances.
Claim 3
Dependent Claim 49 words
In a fluid separator as defined in claim 1, the portion of said fluid conduit extending through said housing being shaped in a spiral form providing a plurality of coils and means drivingly connected to said conduit to continuously rotate the coiled portion of said conduit within said housing.
Claim 4
Dependent Claim 23 words
In a fluid separator as defined in claim 1, said openings extending angularly outwardly from said conduit in the direction of fluid flow.
Claim 5
Dependent Claim 16 words
In a fluid separator as defined in claim 1, said abutments having a substantially rectangular cross-section.
Claim 6
Dependent Claim 35 words
In a fluid separator as defined in claim 1, said abutments having a substantially cone shaped cross-section and having an apex extending in a direction normal to the direction of fluid flow in said conduit.
Claim 7
Dependent Claim 26 words
In a fluid separator as defined in claim 5, said cone shaped abutments having an apex inclined in the direction of fluid flow within said conduit.
Claim 8
Dependent Claim 30 words
In a fluid separator as defined in claim 5, said cone shaped abutments having an apex extending in a direction opposite to the direction of fluid flow within said conduit.
