| 摘要 |
The invention relates to a centrifuge comprising a rotating drum (1) and an ejection element (2) which rotates with the drum so as to eject a cake (3) which has settled on the inside of the drum (1) in the axial direction (4). The ejection element (2) comprises a helix (5) which extends along the full length of the drum. The helix (5) and the drum (1) are kinematically linked in such a way that a reference point (A) on the periphery of the helix rotates in relation to the drum such that it describes a saw-tooth line (6, 8). The gradient ( alpha ) of a first flank (7) of the saw teeth (8) approximately corresponds to the gradient ( beta ) of the helix and a second flank (9) of said saw teeth (8) corresponds to a substantially axial ejection movement. |
