Abstract

1414362 Agitators E LYTZEN and A P THOLLE 26 June 1973 30322/73 Heading B1C [Also in Divisions B7 and Fl] In a bladed wheel or propeller of an agitator in which the blades 6 are freely rotatable in the hub 2 about an axis 5 at right angles to the rotational axis b of the hub, each blade is so formed that with a cross-section of the blade at a distance from the rotational axis of the blade of 0.7 times the radius R of the wheel or propeller the rotational axis of the blade is located outside the blade cross-section at a distance of 2-30% of the diameter of the wheel or propeller from the pressure surface of the blade. The distance c from the rotational axis to the leading edge of the blade is 10-70% of the active width of the blade at the same cross-section.
