Abstract
1511760 Agitating and aerating liquids INGENIEURSBUREAU DWARS HEEDERICK EN VERHEY BV 29 Oct 1976 [31 May 1976] 45049/76 Heading B1C A rotatable surface aerator has a central vertical shaft 1, a plurality of vertical blades 2 mounted at its lower end radially or tangentially thereto, an upwardly divergent cone 3 beneath the blades, the radius of the cone being greater than that of the shaft but less than that of the outer edges 4 of the blades, and a cylinder 5 extending from the upper edges of the cone, each pair of blades being linked by an upwardly and outwardly inclined flat plate 6 above the cone. There may be an opening 12 adjacent at least some of the blades, and on the trailing side of them in operation. Preferably the radius of the cone is 43% that of the aerater, and the inclinations to the horizontal of the cone, the connecting plates and the lower edges 8 of the blades are respectively 30, 25 and 15.
