| 摘要 |
The invention relates to a device for removing materials, especially solid materials, liquid phases having different densities and/or gases, from a liquid, by way of rotation. The inventive device comprises a plurality of filter elements (5, 6, 7) which allow the filtrated liquid to pass and which are mounted in a housing (1) and rotate about an axis of rotation (3). The housing has an inlet opening (28) for the liquid, at least one outlet opening (44) for the solid materials removed by rotation and at least one outlet opening (32) for the filtered liquid. According to the invention, a passage (48) is disposed in the area of or next to the axis of rotation (3) of the filter elements, said passage being provided for materials that have a lesser density than the liquid.
