Abstract
Paper pulp beater of the type having a cylindrical vat, open at its upper part, and closed by a bottom equipped with a rotor over which rises a vertical shaft extending along the central axis of revolution of the vat in the interior of the vat, the lateral wall of the vat having a device for force recirculation of the pulp, in that the recirculation device (7) includes at least one surface element (8, 21) extending substantially circularly along the wall (9) of the beater, running from the wall toward the interior of the vat (1) and toward the upper opening (20) of the beater, over a constant distance (12, 22) so as to form a band of constant width, one of the faces (24) of the element being oriented toward the bottom of the vat, so that the pulp (6) encountering this face (24) is diverted into the interior of the vat in a single direction (FIG. 3).
