To provide a surface aeration blade wheel which generates oxygen transfer efficiency and synthetic liquid force-feed speed substantially higher than the conventional design and can be used for a liquid charge tank, in particular, useful for aeration of sewage and other waste water.
The blade wheel which rotates freely around the shaft line vertical to the surface of static liquid. The blade wheel has a plurality of blades attached to the under side of a disk or a disk-like surface. Each blade has a polyhedral or a curved geometrical shape over the range from a vertical state on the attachment place to the disk to a partially inclined state of the bottom part. Respective blades are disposed while leaving an interval from each other in the circumferential direction around the shaft line and are disposed so as to form an acute angle with respect to radial line when viewed from the rotation shaft line of the blade wheel. The under side part of the blade which is inclined and is not vertical is located on a place of the static liquid surface or below the place. When the blade wheel is rotated, the under part force-feeds the liquid to the upper part of the vertical part of the blades and, thereon, the liquid is released to the above and in the direction of departing to the outside from the blade wheel in the state of a spray umbrella.
