Abstract
Abstract A housing defining a generally cylindrical chamber is provided and the chamber is closed at one end. Inlet structure is provided for admitting fluid flow suspended materials into the chamber intermediate the opposite ends thereof and in a direction extending generally tangentially of the chamber. A tubular vortex finder opens centrally into the housing through the closed end thereof and a generally frusto-conical closure wall is provided at the other end of the chamber and opens toward the closed end thereof. The apex of the closure wall defines a restricted outlet and the tubular vortex finder includes an open inlet end opening toward the outlet and spaced intermediate the closure wall and the inlet structure. The inlet structure is fixed in position longitudinally of the housing, but the frusto-conical closure wall and vortex finder are supported relative to the housing for independent adjustment relative thereto in a direction extending longitudinally of the chamber. Further, the vortex finder may be shifted independent of relative movement between the housing and the closure wall, the closure wall may be shifted independently of relative movement between the housing and the vortex finder and the housing may be shifted independent of relative movement of the closure wall and vortex finder.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
190 words
A cyclone classifier including a housing defining a generally cylindrical chamber, means for admitting fluid flow suspended materials into said chamber adjacent one end thereof and in a direction extending generally tangentially of said chamber, an elongated hollow vortex finder centrally disposed in said chamber adjacent said one end thereof and shiftable longitudinally of said chamber, said vortex finder opening into the chamber toward the other end thereof, inwardly opening generally frusto-conical wall means disposed in and closing the other end of said chamber, said frusto-conical wall means opening inwardly toward and being shiftable toward and away from said one end of said chamber, the apex of said wall means including means defining a restricted outlet, and adjustment means operatively connected between said frusto-conical wall means and said vortex finder and between the combination including said frusto-conical wall means and said vortex finder and said housing for adjustable relative shifting between said frusto-conical wall means and said vortex finder longitudinally of said chamber and adjustable relative shifting between said combination and said housing longitudinally of said chamber independent of relative shifting between said frusto-conical wall means and said vortex finder.
Claim 2
Dependent Claim
190 words
A cyclone classifier including a housing defining a generally cylindrical chamber, means for admitting fluid flow suspended materials into said chamber adjacent one end thereof and in a direction extending generally tangentially of said chamber, an elongated hollow vortex finder centrally disposed in said chamber adjacent said one end thereof and shiftable longitudinally of said chamber, said vortex finder opening into the chamber toward the other end thereof, inwardly opening generally frusto-conical wall means disposed in and closing the other end of said chamber, said frusto-conical wall means opening inwardly toward and being shiftable toward and away from said one end of said chamber, the apex of said wall means including means defining a restricted outlet, and adjustment means operatively connected between said frusto-conical wall means and said vortex finder and between the combination including said frusto-conical wall means and said vortex finder and said housing for adjustable relative shifting between said frusto-conical wall means and said vortex finder longitudinally of said chamber and adjustable relative shifting between said combination and said housing longitudinally of said chamber independent of relative shifting between said frusto-conical wall means and said vortex finder.
Claim 3
Dependent Claim
48 words
The combination of claim 1, wherein said adjustment means includes means for adjusting said vortex finder relative to said housing longitudinally of said chamber independent of adjustment of said frusto-conical wall means and, selectively, simultaneous adjustment of said vortex finder and frusto-conical wall means relative to said housing.
Claim 4
Dependent Claim
48 words
The combination of claim 1 wherein said adjustment means includes means for adjusting said frusto-conical wall means relative to said housing independent of adjustment of said vortex finder relative to said housing and, selectively, simultaneous adjustment of said frusto-conical wall means and vortex finder relative to said housing.
Claim 5
Dependent Claim
202 words
A cyclone classifier including an elongated housing defining a generally cylindrical chamber, closed at one end, inlet means for admitting fluid flow suspended materials into said chamber intermediate the opposite ends thereof and in a direction extending generally tangentially of said chamber, an elongated tubular vortex finder opening centrally into said housing through said one end and shiftable longitudinally of said housing, generally frusto-conical closure wall means disposed in, shiftable longitudinally along and closing the other end of said chamber and opening toward said one end thereof, said vortex finder including an open inlet end opening toward said closure wall, the apex of said wall means including means defining a restricted outlet, said open inlet end being spaced intermediate said outlet and inlet means longitudinally of said chamber, and adjustment means operatively connected between said closure wall means and said vortex finder and between the combination including said closure wall means and said vortex finder and said housing for adjustable relative shifting between said closure wall means and said vortex finder longitudinally of said chamber and adjustable relative shifting between said combination and said housing longitudinally of said chamber independent of relative shifting between said closure wall means and said vortex finder.
Claim 6
Dependent Claim
202 words
A cyclone classifier including an elongated housing defining a generally cylindrical chamber, closed at one end, inlet means for admitting fluid flow suspended materials into said chamber intermediate the opposite ends thereof and in a direction extending generally tangentially of said chamber, an elongated tubular vortex finder opening centrally into said housing through said one end and shiftable longitudinally of said housing, generally frusto-conical closure wall means disposed in, shiftable longitudinally along and closing the other end of said chamber and opening toward said one end thereof, said vortex finder including an open inlet end opening toward said closure wall, the apex of said wall means including means defining a restricted outlet, said open inlet end being spaced intermediate said outlet and inlet means longitudinally of said chamber, and adjustment means operatively connected between said closure wall means and said vortex finder and between the combination including said closure wall means and said vortex finder and said housing for adjustable relative shifting between said closure wall means and said vortex finder longitudinally of said chamber and adjustable relative shifting between said combination and said housing longitudinally of said chamber independent of relative shifting between said closure wall means and said vortex finder.
Claim 7
Dependent Claim
49 words
The combination of claim 4 wherein said adjustment means includes means operative to adjust said closure wall means relative to said housing independent of adjustment of said vortex finder relative to said housing and, selectively, simultaneous adjustment of said closure wall means and vortex finder relative to said housing.
Claim 8
Dependent Claim
54 words
The combination of claim 4 wherein said adjustment means includes means operative to adjustably shift said vortex finder, longitudinally of said chamber, relative to said housing independent of adjustment of said closing wall means relative to said housing and, selectively, simultaneous adjustment of said closure wall means and vortex finder relative to said housing.
Claim 9
Dependent Claim
23 words
The combination of claim 4 wherein said means defining a restricted outlet comprises a replaceable outlet sleeve removably supported from said closure means.
