Abstract
An apparatus includes a materials separator that includes a continuous filter belt disposed around a plurality of rollers. The apparatus also includes a pressure differential system operatively coupled to the separator and configured to adjust a pressure differential across the continuous filter belt. A vacuum is applied to the continuous filter belt and a fluid portion of the slurry on the continuous filter belt is drawn through the continuous filter belt. An apparatus includes a materials separator having a first deck with a first continuous filter belt and a second deck with a second continuous filter belt.
Claims8
A method comprising:
- rotating a continuous filter belt around a plurality of rollers of a materials separator;
- introducing a slurry to the materials separator through an inlet of the separator and onto the continuous filter belt;
- applying a constant vacuum to a first collection pan disposed underneath an inclined portion of the continuous filter belt;
- applying intermittently a vacuum to a second collection pan underneath a horizontal portion of the continuous filter belt;
- and
- drawing a fluid portion of the slurry on the continuous filter belt through the continuous filter belt with the vacuum.
An apparatus comprising:
- a materials separator having a frame, an inlet, and an outlet, the materials separator comprising:
- a first deck comprising a first continuous filter belt disposed around a first set of rollers;
- a second deck disposed below a portion of the first deck, the second deck comprising a second continuous filter belt disposed around a second set of rollers;
- and
- a drive device configured to rotate at least one roller of each of the first and second sets of rollers.
