    • The invention concerns a flotation cell (1; 30) for purifying fibrous suspensions through the dispersion of air microbubbles (22), comprising: a container (2; 31); feed pipes (4; 34) for conveying the suspension (3) into the container (2; 31); means (5; 35) for intercepting the purified suspension; means (6) for extracting the purified suspension; means (7) for discharging the foams created by the impurities contained in the suspension (3); rotary vanes (19; 36) arranged inside the container (2; 31). The cell (1; 30) comprises air dispersers (10; 32; 42) for generating air microbubbles (22) and dispersing them in the suspension (3), in each one of which it is possible to identify one rotor (11; 45) with axial flow associated with driving means (12; 47) and one duct (13; 40; 46) for conveying external air at the level of the rotor (11; 45).
    • 本发明涉及通过空气微泡(22)的分散来净化纤维悬浮液的浮选槽(1; 30),其包括:容器(2; 31); 用于将悬浮液(3)输送到容器(2; 31)中的输送管(4; 34); 用于拦截纯化的悬浮液的装置(5; 35) 用于提取纯化的悬浮液的装置(6) 用于排出由悬浮液(3)中含有的杂质产生的泡沫的装置(7); 设置在容器(2; 31)内的旋转叶片(19; 36)。 该单元(1; 30)包括用于产生空气微泡(22)并将它们分散在悬浮液(3)中的空气分散器(10; 32; 42),在每一个空气分散器中可以识别一个转子(11; 45 )具有与驱动装置(12; 47)相关联的轴向流动和用于在转子(11; 45)的高度处输送外部空气的一个管道(13; 40; 46)。
