摘要:
A reactor (1; 30) for cleaning fibrous suspensions dispersed in liquids, comprising: a substantially cylindrical container (2); one or more rotating blades (3) arranged inside the container (2); a plurality of feed units (5, 6, 7, 8, 9) for feeding the suspension to be cleaned into the container (2) together with a gaseous substance dispersed therein in the form of bubbles; means (14; 16) for intercepting the suspension arranged inside the container (2); means (10) for skimming the foam and the cleaned suspension. Each feed unit (6, 7, 8, 9) comprises at least one feed pipe (6a, 7a, 8a, 9a) which extends into the container (2) and is provided with a plurality of ejectors (6d, 7d, 8d, 9d), each of which have a spray direction (Z) facing the inner surface (2a) of the container (2) for the distribution of the suspension to be cleaned starting from the inside of the cross section (S) of the container (2).
摘要:
Strainer (1) for fibrous suspensions, comprising a container (2), a filtering basket (3; 21, 22) inside the container (2) and a rotor (4; 15, 16) inside the filtering basket (3; 21, 22) coupled to motorization means (7) suited to set it rotating. In the container (2) there are a drain chamber (35) of the rejected suspension, a delivery chamber (25, 27) of the filtered suspension, and a collector body (30) arranged in the upper part of the container (2). The collector body (30) comprises a lower collector (37) and an upper collector (38), both with radial longitudinal profile in the shape of a truncated cone and connected to each other in correspondence with the long bases (37a, 38a). The lower collector (37) has its short base (37b) facing the filtering basket (3; 21, 22) and the upper collector (38) has its short base (38b) facing upwards.
