Agitators.

摘要

An agitator assembly for use in effecting dispersion of a fluid such as a gas in a liquid comprises a rotor having a rotatably driven shaft 18 mounting a series of scoop-shaped blades 20 which are oriented with the mouths 21 of the scoops presented in the direction of rotation of the shaft, each blade being mounted at an angle of attack such that one end of the blade leads the other in the direction of rotation. To eliminate gas cavity formation, each blade is of generally streamlined configuration in section and the ends 30 thereof are generally parallel to the direction of motion of the blade. <IMAGE>
