Dewatering Screw Press

A dewatering screw press comprises:

• an auger;
• a case;
• a motor;
• at least one external screen;
• an intake;
• at least one liquid output comprising a proximal output;
• a solid output;
• the auger comprises an auger body, a first spiraled fin, a cavity, a second spiraled fin, at least one auger aperture, at least one internal screen, a proximal end, and a distal end;
• the auger being positioned within the case between a lower end and an upper end of the case;
• the auger body extending longitudinally from the proximal end to the distal end;
• the intake traversing through the upper end of the case adjacent to the auger;
• the solid output traversing through the case adjacent to the distal end;
• the first spiraled fin being externally connected to the auger body;
• the first spiraled fin longitudinally traversing along the auger body between the proximal end and the distal end;
• the motor being operatively connected to the auger, wherein the motor is configured to rotate the auger about a longitudinal axis of the auger in order to drive influent material received through the intake through the case toward the solid output;
• the cavity internally traversing through the auger body between the proximal end and the distal end;
• the second spiraled fin being internally connected to the auger body within the cavity;
• the second spiraled fin longitudinally traversing within the cavity between the proximal end and the distal end;
• a spiral direction of the first spiraled fin being oriented opposite a spiral direction of the second spiraled fin;
• each of the at least one external screen being positioned around the auger between the proximal end and the distal end, wherein each of the at least one external screen is configured to be permeable to liquid material and impermeable to solid material;
• each of the at least one auger aperture traversing through the auger body into the cavity;
• each of the at least one internal screen being connected within one of the at least one auger aperture, wherein each of the at least one internal screen is configured to be permeable to liquid material and impermeable to solid material;
• and
• the cavity being in fluid communication with the proximal output at the proximal end, wherein the second spiraled fin is configured to impel liquid effluent within the cavity out of the proximal end and into the proximal output.
