Abstract

Abstract The invention concerns a method of an apparatus for separating fluids containing particulate matter into two or more fractions of different densities. A cyclone separator (1) is utilised for this purpose and differs from previous constructions inasmuch as it is a uni-directional, air-cored device having an inlet (7) only for the fluid (A) in the top and two, three or more separate outlets (11, 15, 37, 41, 45, 51) in the bottom, remote from the inlet, one (11, 41) of which outlets extends axially of the separator. In operation particles (as defined in the specification) once separated from the streamline (A') in which they enter the device are constrained against traversing that streamline. Means (5) are provided adjacent the inlet (7) to stabilise the initial flow of fluid. The axially extending outlet (11, 41) may be adjustable and means (55) may be provided for elutriating heavy reject flow (Z). Specific embodiments separate into light reject (X) and accept (Y) fractions; into light reject (X), accept (Y) and heavy reject (Z) fractions; and accept (X) and heavy reject (Z) fractions.

Claims Analysis

Total Claims: 21
Claim 1
Independent Claim 88 words
A method of separating a fluid containing particulate matter into a plurality of fractions in , which the fluid (A) is fed into the top of an air-cored cyclone separator (1) characterised in that the fluid is constrained to adopt a uni-lateral flow within the separator, after separation it is extracted in two or more separated fractions (X, Y) from a region adjacent the bottom of the separator through outlets therein remote from the inlet, and one of the separated fraction (X) is extracted axially of the separator.
Claim 2
Independent Claim 88 words
A method of separating a fluid containing particulate matter into a plurality of fractions in , which the fluid (A) is fed into the top of an air-cored cyclone separator (1) characterised in that the fluid is constrained to adopt a uni-lateral flow within the separator, after separation it is extracted in two or more separated fractions (X, Y) from a region adjacent the bottom of the separator through outlets therein remote from the inlet, and one of the separated fraction (X) is extracted axially of the separator.
Claim 3
Dependent Claim 21 words
A method as claimed in claim 1, characterised in that the inlet fluid is stabilised following its introduction into the separator.
Claim 4
Dependent Claim 26 words
A method as claimed in claim 1 or 2, characterised in that a light reject (X) of denisty less than inlet fluid (A) is extracted axially.
Claim 5
Dependent Claim 26 words
A method as claimed in claim 1 or 2, characterised in that an accept fraction (Y) of lesser density than inlet fluid (A) is extracted axially.
Claim 6
Independent Claim 43 words
A method as claimed in any one of claims 1 to 4, wherein particles once separated from a streamline (A') of the inlet fluid (A) are constrained so that they do not traverse that streamline as they.move towards one of the remote outlet.
Claim 7
Dependent Claim 50 words
A method as. claimed in claim 1, characterised in that the fluid is separated into three fractions, a light reject fraction (X) being extracted through an axially directed outlet 41, whilst an accept fraction (Y) and a heavy reject fraction (Z) are extracted through horizontally directed outlets (45, 37 respectively).
Claim 8
Dependent Claim 89 words
A cyclone separator for separating a fluid containing particulate matter into a plurality of fractions each of different densities characterised in that a fluid inlet (7) only is provided in the upper regions of a uni-directional air-cored cyclone (1), a plurality of outlets are provided, one for each fraction, in the lower region of the device remote from the inlet (7) to extract the several fractions (X, Y, Z) from such lower regions, and that one of the said outlets is arranged to extend axially downwardly from the separator.
Claim 9
Dependent Claim 89 words
A cyclone separator for separating a fluid containing particulate matter into a plurality of fractions each of different densities characterised in that a fluid inlet (7) only is provided in the upper regions of a uni-directional air-cored cyclone (1), a plurality of outlets are provided, one for each fraction, in the lower region of the device remote from the inlet (7) to extract the several fractions (X, Y, Z) from such lower regions, and that one of the said outlets is arranged to extend axially downwardly from the separator.
Claim 10
Dependent Claim 28 words
A cyclone separator as claimed in claim 7, characterised in that a stabiliser (5) is located in the upper region of the separator adjacent the fluid inlet (7).
Claim 11
Dependent Claim 24 words
