摘要： The present invention relates to a method of treating recycled fiber pulp by washing impurities like ash, ink and stickies therefrom. The method is characterized by the steps of spraying the recycled pulp onto a filter surface, removing impurities through the filter surface with the filtrate, allowing a web to be formed on the filter surface, breaking the web, allowing the web to be reformed by removing impurities and filtrate through the filter surface, and discharging the treated recycled pulp from the apparatus. It is typical of the apparatus in accordance with the present invention that at least one means (16) is provided for supplying recycled pulp onto a filter surface, said means being arranged above a horizontal plane passing along the axis of the cylinder (10).

摘要： A method and apparatus for enhancing knot transport in a knot drainer has a provision for decreasing tangential velocity of the feed slurry in the inlet chamber (10), a hydrodynamic force reduction provision in the screening chamber (20), and a provision for increasing the ratio of circumferential friction forces to axial friction forces in a housing extension (40) above the screening chamber (20). This drastically reduces frequency of knot transport interruptions which would otherwise occur in the knot drainer, thereby improving knot drainer performance efficiency.

摘要： A fractionator for fractioning a suspension in at least two fractions, including a drum (1) rotatable about a substantially horizontal shaft (3) and having inlet means (31) for suspension and at least one outlet means for fractions. The drum (1) includes at least two walls (21, 22, ..., 27) curved about the shaft and extending substantially parallel thereto in the longitudinal direction thereof, said walls defining between them a fluid channel substantially parallel to the shaft (3). The drum is open at both ends so that each flow channel defined by a pair of walls (21/22, 22/23, ..., 26/27) has its own inlet and its own outlet, all inlets (31) being located in the one and the same end of the drum and all outlets in the opposite end of the drum.

摘要： A cylinder type paper pulp washer or thickener apparatus includes a rotatable cylinder mold (12) with a forming wire surface (16). The mold (12) rotates at least partially submerged in a vat (10) of dilute paper pulp stock and a differential pressure across the wire surface draws stock from the vat through the cylinder mold (12) and forms a pulp mat on the wire surface (16), and a plurality of disrupters (60) are positioned within the vat (10) and in arcuately spaced relation to the wire surface (16) to cause a disruption of the fiber mat which obstructs the flow of the stock liquid through the wire surface (16) and thereby provides for the reestablishment of flow. Various disrupters are shown, including a rotating non-circular bar, a doctor blade, a foil, a fluid jet, a brush, a triangular protuberance. A plurality of such disrupters (60) are positioned in peripherally spaced relation to cause repeated disruption and reformation of a fiber mat to increase the throughflow and washing or thickening efficiency of the apparatus.

摘要： A device for screening pulp suspensions comprises a cylindric housing (1) with inject inlet (2), reject outlet (3) and accept outlet (4) and screening members in the form of a stator (5) and a rotor (8). The stator (5) as well as the rotor (8) comprise a plurality of annular elements (6 and 9, respectively), which are arranged in a mutual axial spaced relationship. The rotor (8) is located radially outside the stator (5), so that the rotor elements (9) are located directly in front of the spaces between the stator elements (6), and the axial length of the rotor elements is greater than the spaces between the stator elements. Thereby gaps (11) are formed between the stator elements and rotor elements.
