摘要： A method and apparatus is provided for aiding in the removal of a fibrous material sheet from a smooth porous filter surface. An intermittent pattern of round-bottomed compression irregularities is impressed upon the sheet blunt round-edged device to cause it to be released from the filter surface in the areas where the irregularities are impressed by the device so that it will not stick to the filter surface nor split when it is contacted by the doctor device which guides it away from the filter surface. The spacing and the geometry of the compression pattern are according to the pulp characteristics and the operating conditions of the filter.

摘要： An anti rewet deck is provided for press rolls used to increase consistency of fibrous pulp slurry from approximately 4 percent up to about 30 to 50 percent. This is accomplished by biasing the location of the drainage holes in the roll shell to the forward edge of the drainage compartments within the roll shell. To avoid the necessity for handing of the rolls, a mechanism is provided for accomplishing the purposes of minimizing rewet at practical production rates by providing baffle plates which effectively orient the draining pattern in the desired direction. Such baffles can be permanently or removably installed once the desired handing of the rolls is determined.

摘要： A hydrodynamic device for generating negative pressure excursions in a pulp slurry during fine screening, includes a plurality of half-foil members disposed on a substantially cylindrical outer surface of a rotor. The rotor is mounted within and co-axial with a substantially cylindrical screen having a circumferentially continuous apertured zone to define an annular screening chamber between the rotor and the screen. The half-foil members are collectively at least axially co-extensive with the apertured zone and have a leading edge which, also collectively, is inclined at a spiral angle relative to the axis of the rotor such that during rotation, the collective leading edge of the half-foil members conduct large particles downwardly through the screening chamber. A selection of hydrodynamic foil configurations is provided in order to adapt to a wide range of pulp types and screening conditions.
