Abstract

A vibratory apparatus for separating a liquid from a liquid-laden solid material. The apparatus includes an inclined trough having a base with a first end and a second elevated with respect to the first end. A deck is attached to the trough base, the deck defining support points positioned above the base spaced from one another by a distance sufficient to support the solid material above the deck, and passages located between the support points to allow liquid to flow to the deck. A vibratory drive is attached to the trough and oriented impart a conveying motion toward the trough second end. Solid material deposited onto the deck is advanced toward the second end by the conveying motion while the liquid flows along the trough base toward the first end under gravity.

Claims

1. A vibratory apparatus for separating a liquid from a liquid laden solid material, the apparatus comprising:

an inclined trough having a base, the trough defining a solids discharge point and a liquid drainage point;

a deck attached to the trough base, the deck including a plurality of inverted V-shaped angles extending longitudinally along the trough base, each inverted V-shaped angle having a solid first wall surface and a solid second wall surface,

the first and second wall surface of each angle meeting along a first edge at an upwardly oriented apex which defines a support point positioned above the base, the support points of the angles being spaced from one another by a distance sufficient to support the solid material above the base, and the first and second wall surface of each angle having a second edge, the second edges of adjacent angles being spaced to define a passage between adjacent support points, wherein the support points are located at an elevation sufficiently above the base to allow liquid to drain from the solid material and flow through the passage to the trough base; and

a vibratory drive attached to the trough and oriented to impart a conveying motion toward the solids discharge point;

wherein the solid material deposited onto the deck is advanced toward the solids discharge point by the conveying motion while the liquid flows along the trough base toward the liquid drainage point under gravity.

2. The apparatus of claim 1, further comprising a hopper located above the trough for directing the liquid-laden solid material toward a central portion of the trough.

3. The apparatus of claim 1, further comprising spacers positioned between the deck and the trough base.

4. The apparatus of claim 1, in which the solid comprises petroleum coke.

5. The apparatus of claim 1, in which the trough is mounted on a mobile frame.

6. The apparatus of claim 5, in which the frame comprises wheels adapted to travel along tracks.

7. The apparatus of claim 1, in which the vibratory drive comprises a rotating eccentric drive.

8. The apparatus of claim 1, in which the vibratory drive comprises a rotating unbalance drive.

9. The apparatus of claim 1, in which the trough has a first end and a second end, wherein the trough second end is elevated with respect to the trough first end.

10. The apparatus of claim 9, in which the trough second end comprises the solids discharge point and the trough first end comprises the liquid drainage point.

11. A vibratory apparatus for separating a liquid from the liquid-laden solid material, the apparatus comprising:

a first separating unit having;

an inclined trough having a base, the trough defining a solids discharge point and a liquid drainage point;

a deck attached to the trough base, the deck including a plurality of inverted V-shaped angles extending longitudinally along the trough base, each inverted V-shaped angle having a solid first wall surface and a solid second wall surface,

the first and second wall surface of each angle meeting along a first edge at an upwardly oriented apex which defines a support point positioned above the base, the support points of the angles being spaced from one another by a distance sufficient to support the solid material above the base, and the first and second wall surface of each angle having a second edge, the second edges of adjacent angles being spaced to define a passage between adjacent support points, wherein the support points are located at an elevation sufficiently above the base to allow liquid to drain from the solid material and flow through the passage to the trough base; and

a vibratory drive attached to the trough and oriented to impart a conveying motion toward the solids discharge point, wherein the solid material deposited onto the deck is advanced toward the solids discharge point by the conveying motion while the liquid flows along the trough base toward the liquid drainage point end under gravity; and

a second separating unit having;

an inclined trough having a central portion positioned below the trough second end of the first separating unit, the trough having a base and defining a solids discharge point and a liquid drainage point;

a deck attached to the trough base, the deck including a plurality of inverted V-shaped angles extending longitudinally along the trough base, each inverted V-shaped angle having a solid first wall surface and a solid second wall surface,

the first and second wall surface of each angle meeting along a first edge at an upwardly oriented apex which defines a support point positioned above the base, the support points of the angles being spaced from one another by a distance sufficient to support the solid material above the base, and the first and second wall surface of each angle having a second edge, the second edges of adjacent angles being spaced to define a passage between adjacent support points, wherein the support points are located at an elevation sufficiently above the base to allow liquid to drain from the solid material and flow through the passage to the trough base; and

a vibratory drive attached to the trough and oriented to impart a conveying motion towards the solids discharge point, wherein solid material deposited onto the deck is advanced toward the solids discharge point by the conveying motion while the liquid flows along the trough base toward the liquid drainage point under gravity.

12. The apparatus of claim 11, further comprising a hopper located above a central portion of the trough of the first separating unit.

13. The apparatus of claim 11, in which each trough of the first and second separating units further comprises spacers positioned between the deck and the trough base.

14. The apparatus of claim 11, in which the troughs of the first and second separating units are mounted on a mobile frame.

15. The apparatus of claim 14, in which the frame comprises wheels adapted to travel along tracks.

16. The apparatus of claim 11, in which the vibratory drives of the first and second separating units comprise rotating eccentric drives.

17. The apparatus of claim 11, in which the vibratory drives of the first and second separating units comprise rotating unbalance drives.
