Abstract
Abstract A device is provided for discharging the heavy bottom or reject fraction from a vortex-type separator and the device comprises a cylindrical vortex chamber which is connected to a bottom fraction outlet of the separator so as to receive the reject fraction therefrom in a manner producing a vortex flow in the vortex chamber. The vortex chamber is provided with an outlet port for the reject fraction and a flow-deflecting member is disposed within the vortex chamber for deflecting the vortex flow away from the circumferential wall of the vortex chamber at the location of the outlet port. The flow-deflecting member has an adjustable position in the vortex chamber so that the degree of deflection of the vortex flow from the location of the outlet port is determined by the position of the flow-deflecting member.

Claim 1
Independent Claim
196 words
A device for discharging a heavy bottom fraction from a vortex type separator, comprising a substantially cylindrical vortex chamber connected to the separator to receive said heavy bottom fraction therefrom in a manner producing a fluid vortex in the vortex chamber, said vortex chamber having a cylindrical circumferential wall and being provided with a stationary outlet port located at the cylindrical circumferential wall of the vortex chamber, a flow-guiding member disposed in an adjustable position within said vortex chamber, said flow-guiding member having a flow-deflecting surface with an upstream end and a downstream end relative to the vortex flow and extending between said upstream end and said downstream end obliquely relative to the predominating flow direction of the vortex flow, the downstream end of the flow-deflecting surface being located in the vicinity of and upstream of said outlet port such that the flow-deflecting surface will deflect at its upstream end the vortex away from the cylindrical circumferential wall of the vortex chamber at the location of said outlet port, and means for varying the position of said flow-guiding member and thereby the distance between the outlet port and the downstream end of the flow deflecting surface.
Claim 2
Independent Claim
196 words
A device for discharging a heavy bottom fraction from a vortex type separator, comprising a substantially cylindrical vortex chamber connected to the separator to receive said heavy bottom fraction therefrom in a manner producing a fluid vortex in the vortex chamber, said vortex chamber having a cylindrical circumferential wall and being provided with a stationary outlet port located at the cylindrical circumferential wall of the vortex chamber, a flow-guiding member disposed in an adjustable position within said vortex chamber, said flow-guiding member having a flow-deflecting surface with an upstream end and a downstream end relative to the vortex flow and extending between said upstream end and said downstream end obliquely relative to the predominating flow direction of the vortex flow, the downstream end of the flow-deflecting surface being located in the vicinity of and upstream of said outlet port such that the flow-deflecting surface will deflect at its upstream end the vortex away from the cylindrical circumferential wall of the vortex chamber at the location of said outlet port, and means for varying the position of said flow-guiding member and thereby the distance between the outlet port and the downstream end of the flow deflecting surface.
Claim 3
Dependent Claim
107 words
A device as claimed in claim 1, wherein said adjustable flow-deflecting member includes a body forming the bottom of said vortex chamber, said body being rotatable about the axis of symmetry of the vortex chamber and having an upper side facing the vortex chamber including said flow-deflecting surface having a first, substantially semicircular surface perpendicular to the axis of the vortex chamber, a second substantially semicircular surface inclined relative to the axis of the vortex chamber and a triangular surface joining said first and second semicircular surfaces, said triangular surface being parallel to the axis of the vortex chamber and extending substantially diametrically through the vortex chamber.
Claim 4
Dependent Claim
76 words
A device as claimed in claim 1, wherein said adjustable flow-deflecting member includes a body extending close to the circumferential wall of the vortex chamber for a portion only of the complete circumference and having a substantially constant radial breadth and an axial height which increases continuously from the bottom of the vortex chamber in the direction of the vortex flow, said body beiNg rotatable relative to the vortex chamber about the axis of the chamber.
Claim 5
Dependent Claim
79 words
A device as claimed in claim 1, wherein said adjustable flow-deflecting member includes a body extending close to the circumferential wall of the vortex chamber for a portion only of the complete circumference and having a substantially constant axial height substantially corresponding to the axial height of the vortex chamber and a radial breadth which increases continuously in the direction of the vortex flow, said body being rotatable relative to the vortex chamber about the axis of the chamber.
Claim 6
Dependent Claim
127 words
A device as claimed in claim 1, wherein said adjustable flow-deflecting member includes a plate spring having a breadth substantially corresponding to the axial height of the vortex chamber and a length corresponding to a portion only of the circumferential length of the vortex chamber, said plate spring having one end attached to the circumferential wall of the vortex chamber and extending from said one end in the direction of the vortex flow so as to have an opposite end located upstream of the outlet port of the vortex chamber, said means for varying the position of the flow-deflecting member comprising means for varying the position of said opposite end of said plate spring in a radial direction relative to the circumferential wall of the vortex chamber.
