Abstract

1,114,614. Agitating, aerating and circulating liquids. AMES CROSTA MILLS & CO. Ltd. and J. F. BOLTON. 22 Feb., 1967 [25 Feb., 1966], No. 834l/66 Heading BIC. A surface aerator comprises a plurality of propeller blades C the tips of which support an inverted frusto-cone A, optionally by means of a cylindrical neck B, the interior of the cone having angularly spaced blades E. These may be trapezoidal and tangential to the shaft D; they may have a shroud F and an overhanging deflector ring K. There may be external blades attached to the cone A and/or the neck B, which may have a flared skirt. The device may be used alone or with an aligned stationary uptake tube. In operation, the propeller blades C create in the cone A a bead of liquid which is sprayed by the blades E. The lip of the cone may be cut away between the blades, the edges of which may be stepped or castellated, so that the liquid is divided into streamlets.
