Abstract
Abstract A hydroclone for simultaneously separating immiscible heavier liquids from a lighter liquid medium and solids from the lighter liquid including a cylindrical portion having an inlet tangentially intersecting the interior wall and an upper axial outlet, a conical portion axially received within the cylindrical portion, the interior surface of the conical portion being tapered to a reduced diameter vortical opening, the outer diameter of the conical portion being less than the inner diameter of the cylindrical portion providing an annular heavier liquid passageway therebetween, and an underflow pot communicating with the opened bottom cylindrical portion and the vortical opening of the conical portion, the underflow pot receiving expelled heavier liquids and some of larger solid particles through the annular passageway and expelled solids through the vortical opening.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
142 words
An improved hydroclone for simultaneously separting heavier immiscible liquids from a lighter liquid medium and solids from the lighter liquid medium comprising: a cylindrical portion having a closed top and an opened bottom, having a fluid inlet tangentially intersecting the interior wall, and having a fluid outlet axially received in the closed top; a conical portion coaxially received in said cylindrical portion, the interior surface thereof tapering to a reduced diameter axial vortical opening at the lower end thereof, the outer diameter of the conical portion being less than the inner diameter of said cylindrical portion providing an annular heavier liquid passageway therebetween; and an underflow pot communicating with said open bottom of said cylindrical portion and said vortical opening of said conical portion, said underflow pot receiving expelled heavier liquid through said annular passageway and expelled solids through said vortical opening.
Claim 2
Dependent Claim
142 words
An improved hydroclone for simultaneously separting heavier immiscible liquids from a lighter liquid medium and solids from the lighter liquid medium comprising: a cylindrical portion having a closed top and an opened bottom, having a fluid inlet tangentially intersecting the interior wall, and having a fluid outlet axially received in the closed top; a conical portion coaxially received in said cylindrical portion, the interior surface thereof tapering to a reduced diameter axial vortical opening at the lower end thereof, the outer diameter of the conical portion being less than the inner diameter of said cylindrical portion providing an annular heavier liquid passageway therebetween; and an underflow pot communicating with said open bottom of said cylindrical portion and said vortical opening of said conical portion, said underflow pot receiving expelled heavier liquid through said annular passageway and expelled solids through said vortical opening.
Claim 3
Dependent Claim
60 words
An improved hydroclone for simultaneously separting heavier immiscible liquids from a lighter liquid medium and solids from the lighter liquid medium according to claim 1 including: a filter having a fluid inlet opening and a fluid outlet opening, the fluid inlet opening communicating with said underflow pot and the fluid outlet opening communicating with the interior of said conical portion.
Claim 4
Dependent Claim
41 words
An improved hydroclone for simultaneously separating heavier immiscible liquids from a lighter liquid medium and solids from the lighter liquid medium according to claim 2 wherein said filter includes a fluid outlet conduit axially positioned in said conical portion vortical opening.
Claim 5
Dependent Claim
80 words
An improved hydroclone for simultaneously separating heavier immiscible liquids from a lighter liquid medium and solids from the lighter liquid medium according to claim 2 wherein said filter is axially positioned in said underflow pot, said filter having a central fluid receiving chamber and an axially positioned outlet conduit communicating at one end to said fluid chamber at the other end with said conical member vortical opening, said filter receiving the flow of fluid therein around the filter exterior circumference.
Claim 6
Dependent Claim
65 words
An improved hydroclone for simultaneously separating heavier immiscible liquids from a lighter liquid medium and solids from the lighter liquid medium according to claim 1 including: an axial subcone portion affixed to said conical portion lower end, said subcone portion having an axial opening communicating with said conical portion vortical opening and tapering to an enlarged diameter axial outlet opening communicating with said underflow pot.
Claim 7
Dependent Claim
47 words
An improved hydroclone for simultaneously separating immiscible heavier liquids for a lighter liquid medium and solids from the lighter liquid medium according to claim 1 including: spaced apart, radially extending fins between said underflow pot and said conical portion, said fins serving to support said conical portion.
