Abstract

1,192,796. Agitating and aerating liquids. VENOT-PIC S.A. 12 Sept., 1967 [20 Oct., 1966], No. 41642/67. Heading B1C. A rotor for aerating and circulating liquids especially in froth flotation comprises a plurality of generally radial hollow vanes 6 shrouded by discs 7, 8, and externally shaped to provide non-turbulent flow through the rotor. Pulp is circulated as at 10 through the annular aperture 9, and air is sucked or forced down the bore 2 of the shaft 1 and expelled from orifices 11 at the ends of the vanes, which may terminate radially as shown, or at an angle to the radius, and need not extend to the periphery of the discs (see Figs. 4-7, not shown). The ducts 5 in the vanes may increase in crosssection in the direction of air-flow, see Fig. 3 (not shown).
