Press for heterogeneous waste

Press for heterogeneous waste comprising a solid phase and a liquid phase, said press comprising

• (a) a frame (1) supporting a receptacle (2) forming a feed zone (3) receiving heterogeneous waste, said feed zone having an open top and first and second opposing lateral openings (5, 6);
• (b) a compression piston (7) and means for moving said compression piston between said first opening (5) of said feed zone (3) and a position located downstream of said second opening (6) of said feed zone, said first and second openings having a cross-section substantially equal to a cross-section of said compression piston;
• (c) a chamber (9) in which said waste is compressed by said compression piston in order to separate said solid phase and said liquid phase, said chamber being formed by a die (11) with a cross-section substantially equal to said cross-section of said compression piston (7) and comprising calibrated passages (11a) connecting said pressing chamber (9) to a collector (25) located below said pressing chamber for recovery of said liquid phase;
• and
• (d) a hatch (13) located below said pressing chamber for discharge of said solid phase;
• (e) wherein said die (11) is mounted in a slide (12), connected to means for controlling angular displacement of said slide between a first position in which said pressing chamber (9) is in communication with said feed zone (3) and a second position in which said pressing chamber (9) is in communication with said hatch (13), said slide being associated with means for effecting discharge of said solid phase and means for effecting discharge of said liquid phase.
