SCREW CENTRIFUGE WITH A COMPLETE DRUM AND OUTLETS FOR PARTIAL EMPTYING AND REMOVAL OF RESIDUAL PRODUCTS FROM DRUM

摘要

1. A screw centrifuge with a solid drum (1) mounted rotatably preferably around a horizontal axis of rotation, in which a screw (4) is located rotatably, with a device (8) for continuous discharge of the solid phase at one end of the drum (1), a device for continuously discharging a liquid phase at the opposite end of the drum (1) and at least one or more additional periodically acting outlet openings (10) provided with a shutter, characterized in that at least one or several a number of additional outlet openings (10) are coupled as a shutter, which has the possibility of axial movement relative to the axis of the drum and, during operation, rotates together with the drum (1) ring (11), with which the drive mechanism is coupled, which moves the ring to the opening position of the outlet or holes (10) and in the closing position of these holes. ! 2. A screw centrifuge with a solid drum according to claim 1, characterized in that the drive mechanism is made in the form of an inkjet drive mechanism. ! 3. A screw centrifuge with a continuous drum according to claim 2, characterized in that the drive mechanism is made in the form of a hydraulic drive mechanism. ! 4. A screw centrifuge with a solid drum according to any one of claims 1 to 3, characterized in that the outlet openings (10) are made in the form of holes in the casing of the drum (1), in particular, drilled or elongated holes. ! 5. A screw centrifuge with a continuous drum according to any one of claims 1 to 3, characterized in that the outlet openings (10) in the axial direction are located upstream of the continuously operating device
