    摘要: An apparatus for dissolving pulp and producing a paper pulp suspension for use in papermaking. The apparatus comprises a container having a stirring rotor therein and, in the area of the lower wall of the container, an outlet chamber to which is connected a dilution water inlet pipe and an outlet pipe. A plate connected to the stirring elements defines the upper extremity of an outlet space and has a plurality of radial ribs connected thereto and extending downwardly into the outlet chamber. As the plate is rotated, the ribs cause mixing of the suspension which flows downwardly into the outlet chamber together with the dilution water to thereby produce a suspension having a lower consistency than the suspension within the container itself. In order to prevent dilution of the suspension within the main area of the container, a retaining wall is provided on the lower surface of the plate at a position radially outward of the axis of rotation. This wall substantially impedes the flow of the more dilute solution and water between the plate and wall of the container into the main portion of the container itself.

    摘要: The disclosure concerns apparatus for disintegrating waste paper and for sorting out fibers to be recovered from the suspension. There is a disintegrating chamber connected by a gravity feed discharge line to a drum type or vibration sorting device. A circulating member disposed in the disintegrating chamber rotates about an axis that is tilted at a small acute angle from the vertical. A screen located beneath the circulating member separates the disintegrating chamber from a discharge chamber beneath the screen. The screen sorts out coarser particles letting only finer suspension paticles pass into the discharge chamber. A first suspension discharge line communicates with the discharge chamber while a second suspension discharge line communicates with the disintegrating chamber immediately above the screen. Both discharge lines empty into each other and lead to the sorting device. Appropriate slides control flow through the two discharge lines. The preferred sorting device is a horizontally oriented, rotatable, perforated drum and the suspension delivered into the drum is screened, with the good suspension being collected and the coarse material being trapped inside the drum to exit from an end.

    摘要: The disclosure concerns a rotor for use in a pulper for forming a pulp suspension through rotation of the rotor in a pulp container. The rotor is generally conically shaped. Around the exterior of the rotor wind a plurality of helical conveyor elements. Each conveyor element includes a flat surface that is oriented obliquely at an acute angle to the axis of the rotor, and the angle of the conveyor element surface with respect to the rotor axis decreases upwardly along the rotor. On the peripheral edge of the conveyor element at the bottom of the rotor, an additional vane is defined which extends outwardly of the conveyor element. The vane is tilted at a different angle to the rotor axis than the conveyor element and is typically more nearly perpendicular to the rotor axis. The outer peripheral edges of the conveyor element and of the additional vane are sharpened to define cutting edges and may be additionally clad.
