Abstract
(DE)
Hyperboloid-Rührkörper zum Umwälzen von Flüssigkeiten, insbesondere Wasser, Abwasser oder dgl., in dessen Zentrum ein Anschlussabschnitt (2) zum Anschluss an eine hohle Rührwelle (1) vorgesehen ist, dadurch gekennzeichnet, dass der Hyperboloid-Rührkörper als Hohlkörper ausgebildet ist, wobei im Anschlussabschnitt (2) ein zentraler Durchbruch (3) zum Zuführen von Luft vorgesehen ist, und dass stromabwärts des Durchbruchs (3) eine Luftverteilungseinrichtung (9, 10, 11) zum Verteilen von durch den Durchbruch (3) zugeführter Luft hin zu mehreren im Hohlkörper vorgesehenen Luftaustrittsöffnungen (14) vorgesehen ist.
(EN)
A hyperboloid agitator for circulating liquids, in particular water, wastewater or the like, in the centre of which a connection portion (2) for connection to a hollow agitator shaft (1) is provided, characterised in that the hyperboloid agitator is formed as a hollow body, with a central aperture (3) for supplying air being provided in the connection portion (2), and in that an air distribution device (9, 10, 11) for distributing air supplied through the aperture (3) to a plurality of air outlet openings (14) provided in the hollow body is provided downstream of the aperture (3).
(FR)
L’invention concerne un corps d’agitation hyperboloïde destiné à faire circuler des liquides, en particulier, de l’eau, des eaux usées ou similaires, au centre duquel se trouve une partie de raccordement (2) destinée à être raccordée à un arbre d’agitation (1) creux, l’invention se caractérisant en ce que le corps d’agitation hyperboloïde se présente sous forme de corps creux, un passage (3) central destiné à acheminer de l’air se situant dans la partie de raccordement (2), et en ce qu’un dispositif de répartition de l’air (9, 10, 11), destiné à répartir l’air acheminé à travers le passage (3) en direction de plusieurs orifices de sortie d’air (14) ménagés dans le corps creux, se situe en aval du passage (3).
