<p>The invention relates to a flotation device, especially for the cleaning of fibrous suspensions in the paper industry, having an essentially rotationally-symmetrical separating part (1) for air bubbles with dirt particles taken up by them on the one hand and, on the other hand, fibres, and having, in particular, a tangential feed (2) and discharge (5) for cleaned suspension and a central dip tube (14) for the removal of dirt particles and air. The invention is characterised in that the inflow (2) is arranged at the bottom, the outflow (5) at the top and the separating part (1) tapers significantly upwards, the diameter ratio of the largest diameter (D1) to the smallest diameter (D2) (D1/D2) is between 1.2 and 3. <IMAGE></p> |
