ABSTRACT:
A multi-screw auger equipped tank comprises opposing sides sloping downward and inwardly toward one another. A plurality of shaftless screw transfer augers run along the tank bottom. Drivers and transmissions coupled to the transfer augers permit simultaneous rotation of the augers in the same or opposite directions of rotation, at the same or different rotational speeds. Materials within the tank, typically slurries or sludges, can be moved to one end of the tank by the transfer augers. An inclined screw auger is disposed near the end of the tank distal from the location at which materials are deposited in the tank. The inclined screw auger picks up the materials and moves them out of the tank. Baffles in the tank aid in dewatering slurries and sludges. Circulation of materials within the tank may be done by rotating the transfer augers in different directions and/or rotational speeds. The tank may be emptied by the fluid pump for fluids and/or the inclined augers for solids.
