  • Publication number: 20090289004
    Abstract: A vibratory apparatus for separating a liquid from a liquid-laden solid material includes a trough having a base, a deck attached to the trough, and a vibratory drive attached to the trough. The deck includes a plurality of support members extending longitudinally along the trough, each support member having a solid wall surface with an upwardly oriented apex defining a support point and two edges disposed on opposite sides of the upwardly oriented apex, the apexes being spaced from one another by a distance sufficient to support the solid material above the base, the edges of adjacent support members being spaced to define a passage therebetween, and the apexes being located at an elevation sufficiently above the base to allow liquid to drain from the solid material and flow through the passage to the base.

  • Patent number: 7186347
    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.
