Abstract

Apparatus and vibratory separators having a base, a separator housing movably connected with the base, the separator housing including a top having an inlet chute, a bottom having a liquid discharge chute, a cylindrical sidewall defining an axial centerline and having a discharge spout, and at least one screen mounted within the separator housing. A vacuum system proximate the at least one screen may also be incorporated. The apparatus further includes at least one circular force generator (CFG) disposed on the separator housing, and at least one sensor positioned on the apparatus for measuring an operating function associated with and enabled by the vibration profile, and a controller in electronic communication with the sensor and with the at least one CFG. The difference between the measured operating function and the prescribed operating function is reduced. The apparatus may also include at least one CFG having a plurality of imbalanced masses which rotate in a plane parallel the axial centerline. The CFG may be disposed in an annular ring arrangement on the top, on the bottom, or CFGs disposed on both the top and the bottom.

First claim

The invention claimed is:

1. A vibratory separator comprising:
a base;
a separator housing movably connected with the base, the separator housing having an inlet, a discharge chute, and a discharge spout, the discharge spout in communication with an interior of the separator housing and extending from a cylindrical sidewall of the separator housing;
at least one screen mounted within the interior of the separator housing and below the discharge spout;
at least one circular force generator (CFG) disposed on the separator housing;
at least one sensor positioned on the vibratory separator, wherein the sensor measures an operating function associated with and enabled by a vibration profile; and
a controller in communication with the sensor and with the at least one CFG, wherein a difference between the measured operating function and a prescribed operating function is reduced.

2. The vibratory separator according to claim 1 , wherein the at least one CFG comprises a plurality of imbalanced masses which rotate in a plane parallel the axial centerline.

3. The vibratory separator according to claim 1 , wherein the at least one CFG is disposed in an annular ring arrangement on the top.

4. The vibratory separator according to claim 3 , further comprising:
at least one additional CFG disposed in an annular ring arrangement on the bottom.

5. The vibratory separator according to claim 1 , wherein the at least one CFG comprises at least two servo motors which include imbalanced masses at independent angular positions to provide infinite force and phase adjustments.

6. The vibratory separator according to claim 1 , wherein the at least one CFG produces a rotating force vector, wherein the rotating force vector includes a magnitude, a phase, and a frequency, and wherein the at least one CFG creates at least one vibration profile in the vibratory separator.

7. The vibratory separator according to claim 6 , wherein the controller operably controls the force vector based upon the measurement of the operating function, wherein the magnitude, phase and frequency are independently controllable by the controller, and wherein the controller changes the force vector.

8. The vibratory separator according to claim 1 , further comprising:
a system for applying a pressure differential across a screen that increases an amount of fluid passing through the screen.

9. The vibratory separator according to claim 1 , wherein the controller enables forces and phase angles of the at least one CFG to adjust automatically and achieve a targeted motion of the vibratory separator.

10. The vibratory separator according to claim 1 , further comprising:
an auto-vibration control system.
