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 defining support points positioned above the base and spaced from one another by a distance sufficient to support the solid material above the base, and passages located between the support points to allow liquid to flow to the deck; and

a vibratory drive attached to the trough and oriented to impart a conveying motion toward the second end;

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, in which the deck comprises a plurality of V-shaped angles, each V-shaped angle having an apex defining at least one support point, the V-shaped angles extending longitudinally along the trough base.

4. The apparatus of claim 3, in which edges of adjacent V-shaped angles are spaced to define the passages.

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

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

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

8. The apparatus of claim 7, in which the frame comprises wheels adapted to travel along tracks.

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

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

11. 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.

12. The apparatus of claim 11, in which the trough second end comprises the solids discharge point and the trough first end comprises the liquid drainage point.

13. 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 defining support points positioned above the base and spaced by a distance sufficient to support the solid material above the deck, and passages located between the support points to allow the liquid to flow to the deck; and

a vibratory drive attached to the trough and oriented to impart a conveying motion toward the trough second end, 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

an 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 defining support points positioned above the base and spaced by a distance sufficient to support the solid material above the deck, and passages located between the support points to allow the liquid to flow to the deck; and

a vibratory drive attached to the trough and oriented to impart a conveying motion towards the trough second end, 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.

14. The apparatus of claim 13, further comprising a hopper located above a central portion of the trough of the first separating unit.

15. The apparatus of claim 13, in which the trough decks of the first and second separating units each comprise a plurality of inverted V-shaped angles, each V-shaped angle having an apex defining at least one support point, the V-shaped angles extending longitudinally along the trough bases.

16. The apparatus of claim 15, in which edges of adjacent V-shaped angles are spaced to define the passages.

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

18. The apparatus of claim 13, in which the troughs of the first and second separating units are mounted on a mobile frame.

19. The apparatus of claim 18, in which the frame comprises wheels adapted to travel along tracks.

20. The apparatus of claim 13, in which the vibratory drives of the first and second separating units comprise rotating eccentric drives.

21. The apparatus of claim 13, in which the vibratory drives of the first and second separating units comprise rotating unbalance drives.
