Abstract

1499234 Aerating liquids UBUCHIM (SOC de PERSONNES Ó RESPONSIBILITE LIMITEE) 3 Feb 1976 [3 Feb 1975] 04233/76 Heading B1C Apparatus for aerating liquid comprises a centrifugal fan 1 having a plate 3 and blades 5, spaced from and rotatable with a distributor 11 comprising a plate 13 having an aperture 15. In use the aperture 15 is positioned at or adjacent the liquid surface, liquid being drawn through the aperture 15 and air through the aperture 31 by the fan, and an air/liquid mixture ejected at the periphery of the device. The peripheral gap between plates 3, 13 may be adjustable. There may be a stationary or rotatable riser tube 33. In modifications there may be a baffle (40, Fig. 3 not shown) between the plates 1, 11; and the fan plate and/or distributor plate may be flat or dished (see also Figs. 4 and 5, not shown). The fan blades may be cut and pressed out of plate 3 leaving apertures in the plate which then has no central aperture 31. The apparatus may be rotated at 1000-1500 rev/min.
