The invention has set itself the task of. Durehmischueg swirJcungsgrad through, known stirring devices to improve without the need for foreign equipment.

The invention relates to a stirring device with a rotating vane-, cylinder- or disk-like stirrer and consists in designing the latter as a centrifugal pump through channels 1 a of the stirring device. A stirrer rotating in the same direction or moving periodically with different directions of rotation can for this purpose have central "possibly ztx one i for *" ™ * "? the stirrer consists of open channels in the Hührflügel, which open into the hollow Bahrwelle and have wall openings from this.

It is thereby achieved that when a stirrer manufactured according to the invention is immersed in a liquid to be mixed, the channels or seams attached to its interior fill with the liquid which is to be mixed; if the Hührsr is then set in rotation, the liquid is thrown out of the channels or chambers arranged in the Rüarer and through. the openings in the office hollow shaft in the area of the stirrer are sucked in, so that each impeller also creates a circulating flow of liquid. In addition to the iaeciian äunrvirJtedang, a hydrodyaamiacJier Purchaii scnungaeffeJcb is advertised at ά & τ fiotation des Führer ua & epumpte Flüasiglcait. San aann too. Arrange the inlet openings in such a way that the centrifugal pump still mixes outside air or a reactive gas into the mixer, which, for example, can result in foam formation or enrichment with oxygen. The total Sanal cross-section aer in the feeder shaft is adapted to the nal cross-section in the Riihxflügein so that the material repositioned within the feeder is distributed equiaxially to all channels.

In an alternately linka- and clockwise rotating stirrer with channels in the impeller blades and the üührwelle "but has openings no wall * is" achieved that daa Hührgut hocheteigt when changing the Brehrichtung by dan hydrostatic bridge in the channels and aas in re Rotationsbevieguns the stirrer Is expressed so that an additional puffing of the liquid to be mixed takes place in the rhythm of the back and forth movement.

A whisk-like stirrer can thus have several achaial bores guided through the guide shaft or stirrer handle to the bores of the star-shaped ones
