Abstract
Systems and processes for extracting liquids and solids from waste include separately extracting liquids via spaced plates and solid waste out an exit port with an operably counter-pressured pressure cone. The system and process use a cylinder for accepting waste and a piston for providing pressure and pushing waste through the cylinder. Spaced plates with internal apertures are aligned with the cylinder, and pressure from the piston on waste in the apertures forces liquids to pass between the spaced plates. Solid waste egresses via an exit port aligned with the apertures when pressure on a pressure cone operably connected with the exit port exceeds the force keeping the pressure cone closed on the exit port.
Claims18
A system for extracting and separating liquids and solids from waste that contains liquids and solids comprising:
- a cylinder for accepting waste;
- a piston for providing pressure and pushing waste in the cylinder;
- spaced plates with apertures aligned with the cylinder, wherein pressure from the piston on waste in the apertures forces liquids to pass between the spaced plates;
- an exit port aligned with the apertures;
- and
- a pressure cone operably connected with the exit port, wherein pressure from the piston on waste in the cylinder and in the apertures overcomes force of the pressure cone to allow solids to egress out the exit port past the pressure cone,
- wherein the cylinder, piston spaced plates, exit port and pressure cone together comprise an aligned plate press assembly, and further including four aligned plate press assemblies that operate at a quarter turn of a rotating crankshaft.

- a cylinder for accepting waste;
- a piston for providing pressure and pushing waste in the cylinder;
- spaced plates with apertures aligned with the cylinder, wherein pressure from the piston on waste in the apertures forces liquids to pass between the spaced plates;
- an exit port aligned with the apertures;
- and
- a pressure cone operably connected with the exit port, wherein pressure from the piston on waste in the cylinder and in the apertures overcomes force of the pressure cone to allow solids to egress out the exit port past the pressure cone, wherein plate spacing between the spaced plates adjacent to the pressure cone is wider than spacing of the spaced plates closest to the piston.
A system for extracting and separating liquids and solids from waste that contains liquids and solids comprising:
- a cylinder for accepting waste;
- a piston for providing pressure and pushing waste in the cylinder;
- spaced plates with apertures aliened with the cylinder, wherein pressure from the piston on waste in the apertures forces liquids to pass between the spaced plates;
- an exit port aligned with the apertures;
- and
- a pressure cone operably connected with the exit port, wherein pressure from the piston on waste in the cylinder and in the apertures overcomes force of the pressure cone to allow solids to egress out the exit port past the pressure cone, wherein the spaced plates are made of plastic wherein sand can be partially absorbed or pressed into the spaced plates.
