Each filtering section has hole for filtrate, through which inner part of filtering section communicates with axial canal 8 for filtrate discharge. Hole for filtrate is located on rear edge of filtering section in respect to direction of rotation and is connected with front side of axial canal 8 in respect to direction of rotation. As a result of it filtering sections are made so as to be located radially outside and also radially inside axial canals 8. EFFECT: simplified design. 6 cl, 8 dwg
