Abstract

Abstract Each group of conical cyclone separators is arranged in an annular block with their longitudinal axes in a common plane, each side of each block having concentric sealing surfaces coacting with corresponding sealing surfaces of an adjacent similar block to seal against leakage from an inlet opening for supplying the separators. Preferably, the stack of blocks surrounds a central shaft for clamping the blocks together and forming a discharge path for the heavier constituent from the separators, the lighter constituent discharging from the separators at the outer periphery of the stack into a chamber surrounding the stack.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 143 words
A multiple cyclone separator comprising a plurality of groups of conical separators, the cyclone separators of each group being arranged in a circular ring in a common, integral, annular block with the longitudinal axes of the separators disposed in a common plane and directed towards a common center, each said block having at least one inlet opening extending therethrough from both sides thereof and also having radially extending outlet openings for separated components, each block being provided on both sides with sealing surfaces surrounding said inlet opening and adapted to cooperate with corresponding sealing surfaces of adjacent, generally identically shaped blocks, and clamping means for clamping a plurality of said blocks together into sealing engagement with each other and including two pressure plates and a tension rod interconnecting said plates, said rod being tubular and forming an outlet for a discharged separated fraction.
Claim 2
Dependent Claim 143 words
A multiple cyclone separator comprising a plurality of groups of conical separators, the cyclone separators of each group being arranged in a circular ring in a common, integral, annular block with the longitudinal axes of the separators disposed in a common plane and directed towards a common center, each said block having at least one inlet opening extending therethrough from both sides thereof and also having radially extending outlet openings for separated components, each block being provided on both sides with sealing surfaces surrounding said inlet opening and adapted to cooperate with corresponding sealing surfaces of adjacent, generally identically shaped blocks, and clamping means for clamping a plurality of said blocks together into sealing engagement with each other and including two pressure plates and a tension rod interconnecting said plates, said rod being tubular and forming an outlet for a discharged separated fraction.
Claim 3
Dependent Claim 200 words
A multiple cyclone separator comprising a plurality of groups of conical cyclone separators, the cyclone separators of each group being arranged in a circular ring in a common, integral, annular block with the longitudinal axes of the separators disposed in a common plane and directed toward a common center, each said block having at least one inlet opening extending therethrough from both sides thereof and also having radially extending outlet openings for separated components, each block being provided on both sides with sealing surfaces surrounding said inlet opening and adapted to cooperate with corresponding sealing surfaces of adjacent, generally identically shaped blocks, clamping means for clamping a plurality of said blocks together into sealing engagement with each other, an outer housing surrounding the outer periphery of the blocks and forming therewith an annular outlet passage, and a cylindrical mantle between said outer housing and the outer periphery of the blocks, a first part of said outlet passage extending downward between said outer periphery and said mantle, a second part of said outlet passage extending upward between said mantle and outer housing, said housing having a top portion with an outlet to which said second part of the outlet passage leads.
Claim 4
Dependent Claim 200 words
