Fluid and solid material separator

A materials separator comprising:

• a frame;
• an inlet at a first end of the materials separator;
• a first deck comprising:
• a first set of rollers including:
• a first roller positioned at the first end of the materials separator;
• and
• a second roller positioned at a second end of the materials separator opposite the first end of the materials separator;
• a first continuous filter belt disposed around the first set of rollers and extending between the first roller and the second roller;
• a first deck top surface extending between the first roller and the second roller and defined by the first continuous filter belt;
• a first deck bottom surface extending between the first roller and the second roller and defined by the first continuous filter belt, wherein the first deck bottom surface is positioned below the first deck top surface such that a first fluid path of a fluid flows from the inlet, downward through the first continuous filter belt at the first deck top surface to separate first solids from the fluid, and downward from the first deck top surface through the first continuous filter belt at the first deck bottom surface;
• and
• a first solids outlet at the second end of the materials separator for expelling the first solids separated from the fluid off the first continuous filter belt and over the second roller at the second end of the materials separator;
• a second deck disposed below the first deck, the second deck comprising:
• a second set of rollers positioned beneath the first set of rollers, the second set of rollers including:
• a third roller positioned at the first end of the materials separator;
• and
• a fourth roller positioned at the second end of the materials separator;
• a second continuous filter belt disposed around the second set of rollers such that a second fluid path of the fluid flows downward through the second deck to separate second solids from the fluid;
• and
• a second solids outlet at the second end of the materials separator for expelling the second solids separated from the fluid off the second continuous filter belt and over the fourth roller at the second end of the materials separator;
• a flowback pan positioned between the first deck bottom surface of the first deck and the second deck and angled downward from the second end toward the first end such that a flowback fluid path of the fluid flows from the first fluid path at the first deck bottom surface, downward along the flowback pan and to the second fluid path at the second deck;
• and
• a drive device configured to rotate at least one roller of each of the first set of rollers and the second set of rollers.
