Separator and method of separation with a pressure differential device
A system including a vibratory separator includes at least one screen and a pressure differential system. The pressure differential system includes a pressure differential generating device, a tray coupled to the pressure differential generating device, and an adjustable mounting mechanism configured to couple the tray within the vibratory separator and adjust a distance between the tray and the at least one screen of the vibratory separator.
1. A system for separating and drying solids from a slurry, comprising:
a vibratory separator that includes a screen;
a pressure differential generating device; and
a tray coupled to the pressure differential generating device and disposed beneath the screen of the vibratory separator, the tray comprising
a trough proximal or in contact with the screen,
a pan slidably received by a support structure of the vibratory separator, and
a mounting mechanism coupling the trough and the pan.
2. The system of claim 1 , wherein the mounting mechanism is an adjustable mounting mechanism to adjust a distance between the tray and the screen of the vibratory separator.
3. The system of claim 1 , further comprising a gasket disposed on an upper perimeter of the trough to create a seal between the tray and the screen of the vibratory separator.
4. The system of claim 1 , wherein the pressure differential generating device generates a pressure differential across the screen by increasing a velocity of a motive fluid moving through the pressure differential generating device.
5. The system of claim 1 , wherein the pressure differential generating device includes a vacuum generator.
6. The system of claim 2 , wherein the adjustable mounting mechanism is a screw-jacking mechanism.
7. The system of claim 1 , further comprising a screen spacer to displace a portion of the screen of the vibratory separator a selected distance outside a basket of the vibratory separator.
8. A pressure differential system for creating a pressure differential across a screen of a vibratory separator, comprising:
a pressure differential generating device;
a tray coupled to the pressure differential generating device, the tray comprising
a trough including an opening and configured to be proximal or in contact with the screen,
a pan configured to slide onto or into a support structure of the vibratory separator, and
a mounting mechanism coupling the trough and the pan; and
a conduit extending between the pressure differential generating device and the opening in the tray;
wherein a volume between the tray and the screen is in fluid communication with the pressure differential generation device.
9. The pressure differential system of claim 8 , wherein the mounting mechanism is an adjustable mounting mechanism to adjust a distance between the trough and the screen.
10. The pressure differential system of claim 9 , further comprising a gasket disposed on an upper perimeter surface of the trough to create a fluid-tight seal between the tray and the screen.
11. The pressure differential system of claim 10 , wherein the pressure differential generating device generates a pressure differential across the screen by increasing a velocity of a motive fluid moving through the pressure differential generating device.
12. The pressure differential system of claim 11 , wherein the pressure differential generating device includes a vacuum generator.
13. The pressure differential system of claim 12 , wherein the adjustable mounting mechanism is a screw-jacking mechanism.

providing a slurry of solids mixed with a liquid to a screen of a vibratory separator; and
actuating a pressure differential generating device, wherein:
the pressure differential generating device is coupled by a conduit to an opening of a tray comprising
a trough disposed beneath the screen and including the opening,
a pan slidably received by a support structure of the vibratory separator, and
a mounting mechanism coupling the trough and the pan;
the tray is coupled by a gasket disposed along an upper perimeter of the trough to the screen; and
actuating the pressure differential generating device generates a pressure differential across the screen.
15. The method of claim 14 , wherein the mounting mechanism includes an adjustable mounting mechanism pressing the trough against the screen to create a fluid-tight seal.
16. The method of claim 15 , wherein the pressure differential generating device generates the pressure differential across the screen by increasing a velocity of a motive fluid moving through the pressure differential generating device.
17. The method of claim 16 , wherein the pressure differential generating device includes a vacuum generator.
