| 摘要 |
The invention is a rotor (1) for fibrous suspension strainers, comprising a central body (2) with substantially circular cross section, in which it is possible to identify a bottom base (4), a top base (3) and a vertical rotation axis (K) and a plurality of shaped blades (6; 16, 18, 20) protruding from the outer lateral surface (5) of the central body (2). In each blade (6; 16, 18, 20) the direction (X, Y, Z) defined by at least one of the front edges (7, 8, 9) is inclined in the direction opposite the direction of rotation (É) of the rotor (1) and forms an acute angle (±', ²', ³') with any other coplanar direction (X, Y, Z) that intersects it, defined by the intersection of the blade (6; 16, 18, 20) and any vertical sectioning plane (±, ², ³) passing through the vertical rotation axis (K). |
