Abstract

Abstract The invention pertains to a liner for a cyclone comprising a body whose inner surface defines a longitudinal passageway through the body, the passageway including a conical section, the surface defining the passageway having a lesser wear portion and a greater wear portion. The liner body comprises a hollow bladder with an internal circumferential recess and a generally tubular insert disposed in the recess. The insert defines the greater wear portion of the passageway.

Claims Analysis

Total Claims: 22
Claim 1
Independent Claim 136 words
A liner for a cyclone comprising a body having a surface defining a longitudinal passageway through said body, said passageway including a generally conical section, said surface defining said passageway having a lesser wear portion and a greater wear portion, said liner body comprising a hollow bladder having an internal circumferential recess therein, and a generally tubular insert disposed in said recess and defining said greater wear portion of said surface, said recess and said insert having engaged side surfaces, said side surfaces having diameters decreasing in a direction extending longitudinally away from the larger end of the conical section of said passageway and toward the smaller end of the conical section of said passageway whereby said insert is restrained against longitudinal movement with respect to said bladder in the direction of decrease of said diameters.
Claim 2
Dependent Claim 136 words
A liner for a cyclone comprising a body having a surface defining a longitudinal passageway through said body, said passageway including a generally conical section, said surface defining said passageway having a lesser wear portion and a greater wear portion, said liner body comprising a hollow bladder having an internal circumferential recess therein, and a generally tubular insert disposed in said recess and defining said greater wear portion of said surface, said recess and said insert having engaged side surfaces, said side surfaces having diameters decreasing in a direction extending longitudinally away from the larger end of the conical section of said passageway and toward the smaller end of the conical section of said passageway whereby said insert is restrained against longitudinal movement with respect to said bladder in the direction of decrease of said diameters.
Claim 3
Dependent Claim 23 words
A liner according to claim 1 wherein said greater wear portion is located generally in the smaller diameter portion of said conical section.
Claim 4
Dependent Claim 14 words
A liner according to claim 1 wherein said insert is removable from said recess.
Claim 5
Dependent Claim 18 words
A liner according to claim 3 wherein said bladder and said insert are comprised of the same material.
Claim 6
Dependent Claim 24 words
A liner according to claim 1 wherein said passageway further includes a generally cylindrical section adjacent the larger diameter portion of said conical section.
Claim 7
Dependent Claim 36 words
A liner according to claim 1 wherein said bladder is formed of a first material and said insert is formed of a second material, said second material having greater wear resistance characteristics than said first material.
Claim 8
Dependent Claim 35 words
A liner according to claim 6 wherein said second material is relatively frangible and said first material is relatively compressible whereby said bladder radially outwardly of said insert forms a protective backing for said insert.
Claim 9
Dependent Claim 19 words
A liner according to claim 6 wherein said first material is relatively rigid and said second material is flexible.
Claim 10
Dependent Claim 19 words
A liner according to claim 6 wherein said first material is flexible and said second material is relatively rigid.
Claim 11
Dependent Claim 194 words
In a cyclone comprising a housing defining a chamber, said chamber having a generally conical section, said housing also having an inlet, a first outlet, and a second outlet: a liner disposed within said chamber, said liner comprising a body having a surface defining a longitudinal passageway through said body said passageway including a generally conical section radially adjacent said conical section of said chamber, said surface defining said passageway having a lesser wear portion and a greater wear portion, said liner body comprising a hollow bladder, said bladder having an internal circumferential recess therein, and a generally tubular insert disposed in said recess and defining said greater wear portion of said surface, said recess and said insert having engaged side surfaces, said side surfaces having diameters decreasing in a direction extending longitudinally away from the larger end of the conical section of said passageway whereby said insert is restrained against longitudinal movement with respect to said bladder in the direction of decrease of said diameters, said liner also having a first opening coaxial with said first outlet, a second opening coaxial with said second outlet, and a third opening registering with said inlet.
Claim 12
Dependent Claim 194 words
In a cyclone comprising a housing defining a chamber, said chamber having a generally conical section, said housing also having an inlet, a first outlet, and a second outlet: a liner disposed within said chamber, said liner comprising a body having a surface defining a longitudinal passageway through said body said passageway including a generally conical section radially adjacent said conical section of said chamber, said surface defining said passageway having a lesser wear portion and a greater wear portion, said liner body comprising a hollow bladder, said bladder having an internal circumferential recess therein, and a generally tubular insert disposed in said recess and defining said greater wear portion of said surface, said recess and said insert having engaged side surfaces, said side surfaces having diameters decreasing in a direction extending longitudinally away from the larger end of the conical section of said passageway whereby said insert is restrained against longitudinal movement with respect to said bladder in the direction of decrease of said diameters, said liner also having a first opening coaxial with said first outlet, a second opening coaxial with said second outlet, and a third opening registering with said inlet.
Claim 13
Dependent Claim 36 words
A cyclone according to claim 10 wherein said bladder is formed of a first material and said insert is formed of a second material, said second material having greater wear resistance characteristics than said first material.
Claim 14
Dependent Claim 35 words
A cyclone according to claim 11 wherein said second material is relatively frangible and said first material is relatively compressible whereby said bladder radially outwardly of said insert forms a protective backing for said insert.
Claim 15
Dependent Claim 25 words
A cyclone according to claim 10 wherein said greater wear portion is located in the smaller diameter portion of said conical section of said passageway.
Claim 16
Dependent Claim 38 words
A cyclone according to claim 10 wherein said second outlet is located in the smaller diameter portion of said conical section, said cyclone further including means adjacent said second outlet for varying the diameter of said second outlet.
Claim 17
Dependent Claim 51 words
A cyclone according to claim 14 wherein said means for varying the diameter of said second outlet includes an annulus of deformable material adjacent to and coaxial with said second outlet, and means for longitudinally compressing said annulus to cause said deformable material to flow into the opening of said annulus.
Claim 18
Dependent Claim 19 words
A cyclone according to claim 15 wherein said annulus is disposed axially adjacent said second opening of said liner.
Claim 19
Dependent Claim 30 words
A cyclone according to claim 15 wherein said liner has a tubular extension coaxial with said second opening, said extension including a flexible part, and said annulus surrounding said part.
Claim 20
Dependent Claim 19 words
A cyclone according to claim 17 wherein said extension of said liner comprises a tubular extension of said bladder.
Claim 21
Dependent Claim 19 words
A cyclone according to claim 17 wherein said extension of said liner comprises a tubular extension of said insert.
Claim 22
Dependent Claim 22 words
A cyclone according to claim 17 wherein said extension of said liner comprises coaxial tubular extensions of said bladder and said insert.
