Definitions
- Selectors which are intended for the separation and classification of solid particles held in suspension in a gaseous fluid, and which essentially comprise a cylindrical body which is extended at the bottom end thereof by an inverted frustum of a cone and at the top end thereof by a distributor fore-body into which the gaseous fluid is injected, preferably tangentially; the said fore-body is fitted inte nally with a cone through which there takes place a sucking action from the bottom to the top, and the base of which is separated from the internal wall of the fore-body by guide-vanes.
- the gaseous fluid which is charged with particles flows downward in a vortical motion inside the fore-body, passes out through the guide-vanes, continues to flow downward in vertical motion inside the cylindrical body then inside the inverted frusto-conical extension of this latter while encountering one or a number of additiveair or rinsing-air intakes.
- the largest particles of matter are carried towards the wall of the selector whereas the finest particles move toward the axis of the selector.
- the finest particles get close to the axis, due to the fact that pressure at the top of the selector is lower than the pressure at the bottom, the finest particles are sucked upwardly and are removed at the top of the cone provided in the fore-body.
- a first improvement consists in employing only a single rinsingair intake and in making provision, substantially at the same level as the said air-intake and in the interior of the selector, for a central deflector cone which is adapted to move vertically and the height of which can be adjusted at will.
- a second improvement whether employed in combination with the preceding improvement or not, consists in providing the cylindrical body of the selector with a depth, between the outlet of the guide-vanes and the commencement of the bottom cone frustum, which is at least equal to four-fifths of the diameter of said cylindrical body, and in giving to the aboveunentioned cone frustum a depth which is at least equal to the depth of the cylindrical body which is located above this latter.
- the reference numeral 1 designates the cylindrical body of the selector
- the reference 2 designates the inverted cone frustum which forms a downward extension of said cylindrical body
- the reference 3 designates the fore-body which forms an upward extension of said cylindrical body
- the reference 4 designates the cone disposed in the interior of said fore-body
- the reference 5 designates the pipe through which the gaseous fluid charged with solid particles is injected, preferably tangentially, into the fore-body, while 3,232,430 Patented Feb.
- the numerical 6 refers to the ring of guide-vanes between the base of the cone 4 and the Wall of the fore-body 3
- the numeral '7 refers to a rinsing-air intake
- 8 designates a vertically movable, imperforate central deflector cone with its control rod 9.
- the inlets 5 and 7 are arranged so that the fluid streams flowing therethrough circulate in the same circumferential direction within the selector.
- the vertically movable central deflector 8 has an upper portion in the shape of an inverted frustum of a cone, the generatrix of which is substantially parallel to the generatrix of the internal wall of the inverted frustum of a cone 2, and the lower end of the deflector has the shape of an inverted cone.
- the depth of the cylindrical body 1 between the outlet of the guide-vanes 6 and the commencement of the bottom cone frustum 2 is at least equal to four-fifths of the diameter of said cylindrical body.
- the cone frustum 2 has a depth which is at least equal to that of the cylindrical body 1 which is located above said cone frusturn.
- the entire quantity of rinsing air which is supplied through the intake 7 must also pass through this space before reaching the top of the deflector and the velocity of said rinsing air will be more or less high depending on whether the position of the deflector cone 8 is made to form between said cone and the internal wall of the deflector a space which is more or less wide.
- the flow of the rinsing air is shown by the broken lines 12.
- the rinsing air exits through the upper end of the cone 4 as indicated at 15.
- some air enters through the lower end of the body 1 as indicated by arrows 13 and the solids are discharged through said lower end as indicated by arrows 14.
