Abstract
The invention describes separation systems and methods for separating solids and liquids from one another. The system includes a rotating screen for supporting a slurry of solids and liquid. A fluid manifold is configured to the lower surface of the screen for applying a downward vacuum force through the screen. A cleaning manifold is configured to the screen for cleaning the screen.
Claims21
A solids/liquid separation system for separating solids and liquids within a slurry from one another, the separation system comprising:
- a screen operatively connected to a supporting frame, the screen supporting the slurry on an upper surface of the screen when the screen rotates about an axis of rotation;
- a fluid manifold operatively connected to a lower surface of the screen and wherein the fluid manifold is configured to enable a vacuum pressure to be applied in a first direction and to a first portion of the screen while the screen is rotating to convey fluids through the screen;
- a cleaning manifold operatively connected to the screen and wherein the cleaning manifold is configured to enable an air flow pressure to be applied to a second portion of the screen in a second direction generally opposite to the first direction while the screen is rotating;
- wherein the vacuum pressure in a first direction draws fluid through the screen into the fluid manifold and the air flow pressure in the second direction induces air flow through the screen in the second direction to clean the rotating screen.

A method of separating solid and liquids from within a slurry comprising the steps of:
- a) introducing the slurry to an upper surface of a screen while the screen is rotating about an axis of rotation;
- b) applying a vacuum force to a portion of the lower surface of the screen and in a direction generally perpendicular to a surface of the screen to draw fluids through the screen;
- and,
- c) applying an air flow pressure to the screen at a second position of the screen and in a direction generally opposite to the direction of flow as defined in step b) relative to the screen to induce air flow through the screen and effect cleaning of the screen.
