Abstract: 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).

Abstract: The invention is a filtering basket (1; 100) for fibres in water dispersion, comprising a plurality of profiled bars (2, 3; 103) arranged side by side to define a tubular structure with the inner lateral surface provided with a plurality of longitudinal slots (F) that define a filtering surface; two or more annular elements (8) coaxial to one another and spaced from one another, coupled by interference outside the profiled bars (2, 3; 103). The profiled bars (2, 3; 103) comprise a plurality of main bars (2), each one of which is provided with a shaped edge (4) whose cross-section is in the form of a trapezium and has the long side (4a) facing towards the inside of the basket (1; 100) and a plurality of secundary bars (3, 103), each one of which is provided with a shaped edge (5) whose cross-section is curved, with the convex part facing towards the inside of the basket.

Abstract: The invention discloses a kneader for the preparation of paper stuff comprising: a substantially cylindric tank (2; 120) having on the internal wall vertical ribs (21) able to interrupt the rotation of the stuff stream; a rotor (13; 130) having a vertical axis (X; Y) located inside said tank (2; 120) and provided with blades (32; 132) spiral shaped. The external edge of each said blade presents a holding wing (34; 134) which is continuous and oriented towards the bottom of the tank and said wing develops itself from the beginning of each blade, starting from the rotor part farthest from the bottom, ending almost at one turn before the end of the spiral on the bottom.
