Abstract:
1. A system for extracting liquid from a mass comprising: a portable platform having an upper surface; a system mass input; a polymer feeding and blending system on the upper surface; a liquid extraction assembly on the upper surface; and piping having a first section between the system mass input and the polymer feeding and blending system, and a second section between the polymer feeding and blending system and the liquid extraction assembly; wherein the system is configured to have mass inputted into the system mass input, transport the mass to the polymer feeding and blending system through the first section of the piping, inject polymer from the polymer feeding and blending system into the mass, and transport the mass from the polymer feeding and blending system to the liquid extraction assembly; wherein pressure from mass forced into the liquid extraction assembly forces at least a portion of liquid in the mass to exit the mass; wherein the liquid extraction assembly includes a housing having an inlet and an outlet, with the housing further including a path between the inlet and the outlet, the housing being configured to have the mass forced into the inlet to move the mass from the inlet to the outlet, the housing including two substantially parallel rotating screens adjacent the path, each of the rotating screens defining one wall of the path, each of the rotating screens including a plurality of parallel elongated non-circular slots located at the path; wherein pressure from mass forced into the input presses the mass against the slots of the rotating screens to thereby force at least a portion of liquid in the mass to pass through the elongated slots of the rotating screens; and wherein the two substantially parallel rotating screens rotate side by side and are apart from one another, with the path extending between the screens.
