Abstract
A device for separating the liquid phase from the solid phase of rigid multiphase materials such as bituminous schists, domestic waste and vegetables, in which there is used at least one compression operation at a pressure of at least 500 bars, the compression being effected in at least a first elongated chamber (2) having orifices (4) adapted to let the fluid materials pass, a pressure being applied at an inlet end (1a) by a piston (3), the volume of the chamber exceeding the volume swept out by the piston so that the compressed material remains under pressure in the chamber during several strokes of the piston, the other end (1b) of the chamber being equipped with an extraction-metering system (5) so as to allow the permanent pressure of the material in the chamber.
Claims10
A device for separating the liquid phase form the solid phase of rigid multiphase materials such as bituminous schists, domestic waste and vegetables, said device comprising a cylindrical longitudinal chamber (1) having orifices (4) in its cylindrical wall, said chamber having an inlet end (1a) and an outlet end (1b), the inlet end having a lateral loading opening (2), a first axial compression piston (3) mounted within said cylindrical longitudinal chamber (1) at said inlet end and being operated by a hydraulic jack (6), the volume of the chamber being substantially greater than the stroke volume of the first axial compression piston (3) to permit the compacted material to remain in the chamber for a time interval substantially greater than one cycle;
- whereby, the material therein are exposed to compression pressure during a number of cycles which enables the fluid material to be extracted in the desired proportion, and the outlet end being open and equipped with an extrcation and metering system (5) responsive to the pressure in the hydraulic jack (6) operating said first axial compression piston (3) so as to maintain a minimum pressure in the chamber even during the return stroke of the first axial compression piston 3.
A device for separating the liquid phase from the solid phase of rigid multiphase materials such as bituminous schists, domestic waste and vegetables, said device comprising a cylindrical longitudinal chamber having orifices (4) in its cylindrical wall, said chamber having an inlet end (1a) and an outlet end (1b), the inlet end having a lateral loading opening (92), a first axial compression piston (3) mounted within said cylindrical longitudinal chamber (1) at said inlet end and being operated by a hydraulic jack (6), the volume of the chamber being substantially greater than the stroke volume of the first axial compression piston (3), and the outlet end being open and equipped with an extraction and metering system (5) conditioned by the pressure in the hydraulic jack (6) operating said first axial compression piston (3) so as to maintain a minimum pressure in the chamber even during the return stroke of the first axial compression piston (3), and wherein said extraction and metering system further comprise at least one non-tangential rotary cylinder (21, 22) within said first longitudinal chamber (1), mounted for rotation about its axis for selectively imposing in one position unrestricted passage of the materials through the outlet end and in another position a partial obstruction of the chamber to vary the maximum cross-section of the outlet end of said chamber (1).
