Abstract
876,619. Mixing liquids. FIRTH CLEVELAND Ltd. July 2, 1957 [Dec. 7, 1956], No. 1328/61. Divided out of 876,611. Class 86 [Also in Group XXVI] A mixer for viscous liquids comprises a rotor formed with blades 2 extending between end discs 3 which carry stub shafts 5. The outer and inner edges of the blades are curved along their length so that the blades are deeper at the mid-place 93 than at each end of the rotor. The blades are curved in cross-sections normal to the rotor axis, with their concave surfaces facing in the direction of rotation. The chords of the blade sections are tilted forwardly in the direction of rotation with respect to a radial line at their inner edges, at an angle of about 45 degrees at each end of the rotor and at an angle of 30 degrees adjacent the plane 93. As shown by the flow lines, the liquid flows inwardly at each end of the rotor and then outwardly adjacent the plane 93, setting up free toroidal vortices having cores V.
