Abstract
Abstract A device is provided for discharging the heavy bottom or reject fraction from a vortex type separator. The device comprises a vortex chamber disposed underneath the bottom fraction outlet of the separator with the axis of symmetry of the vortex chamber parallel to the axis of symmetry of the bottom fraction outlet. The vortex chamber is provided with a stationary outlet port for the reject fraction, located in the circumferential wall of the vortex chamber or in the bottom of the vortex chamber close to the circumferential wall thereof. The vortex chamber is displaceable relative to the bottom fraction outlet in a direction perpendicular to the axis of symmetry of the vortex chamber. By displacing the vortex chamber relative to the bottom fraction outlet of the separator it is possible to vary the flow volume of the bottom fraction being discharged through the outlet port of the vortex chamber.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
121 words
A device for discharging a heavy bottom fraction from a vortex type separator, comprising a vortex chamber disposed underneath and in flow communication with a bottom fraction outlet from the separator, with the axis of symmetry of said vortex chamber parallel to the axis of symmetry of said outlet, said vortex chamber being provided with an outlet port provided in the area of the circumferential wall of said vortex chamber, anD means for displacing said vortex chamber relative to said outlet in a direction substantially perpendicular to said axis of said symmetry of the vortex chamber, whereby the flow volume of the bottom fraction being discharged through said outlet port can be varied by displacing said vortex chamber in said direction.
Claim 2
Independent Claim
121 words
A device for discharging a heavy bottom fraction from a vortex type separator, comprising a vortex chamber disposed underneath and in flow communication with a bottom fraction outlet from the separator, with the axis of symmetry of said vortex chamber parallel to the axis of symmetry of said outlet, said vortex chamber being provided with an outlet port provided in the area of the circumferential wall of said vortex chamber, anD means for displacing said vortex chamber relative to said outlet in a direction substantially perpendicular to said axis of said symmetry of the vortex chamber, whereby the flow volume of the bottom fraction being discharged through said outlet port can be varied by displacing said vortex chamber in said direction.
Claim 3
Dependent Claim
21 words
The device as defined in claim 1, wherein said outlet port is located in said circumferential wall of the vortex chamber.
Claim 4
Dependent Claim
25 words
