An auto-aspirating, rotational dispersion device for gases and liquids with a rotating hollow shaft employed for gas suction and gas channels communicating with said hollow shaft to openings in the gas channels that are positioned at intervals over the circumference of the device, at which openings the gas and liquid are mixed. The device is distinguished by the fact that the gas being dispersed flows in a manner separate from the liquid, from the hollow shaft through the gas channels and is mixed with the liquid outside of the device.

Auto-aspirating rotational dispersion device

A stirring element (10), especially a gasing stirring element for stirring liquids and introducing a gas, preferably air, to the liquids. The stirring element has a hub (12) for attachment to a stirring shaft and a support disk (14) joined to the hub (12), a plurality of stirring blades (16) being attached to a peripheral edge of the support disk (14). To achieve a low output power coefficient, each stirring blade (16) is made of a wedge-shape that is directed in the direction of rotary motion of the stirring element (10). Preferably, radially inner end sections (22, 24) of two sides (18, 20) of the stirring blade (16) are angled relative to sides (18, 20) outwardly with reference to the direction of rotary motion of the stirring element (10). The stirring element (10) simplifies gas feed and prevents clogs. By providing the support disk (14) with a conical shape having a ring of teeth (26) on its outer edge, a uniform distribution and good dispersion of the gas bubbles is obtainable.

Stirring element for stirring gases into liquids

The present invention generally pertains to an agitating element for agitating low-to-medium-viscosity liquids. The agitating element comprises an inner main blade and an outer side blade, and the two blades are integrally constructed. The main blade is angled with respect to the rotation axis of the agitating element, while the side blade is angled with respect to the rotation plane of the agitating element. The agitating element according to the current invention enables high hydraulic efficiency especially in a vertical direction so as to accomplish thorough mixing of the material with a minimal energy input.
