Apparatus for treating cellulose pulp with intermeshing disks and asymmetrically pulp moving means

Apparatus for treating cellulose pulp having a consistency above the flowage limit, comprising two spaced shafts rotatable in the same axial plane, each shaft carrying means for working said pulp in a working zone, said working means defining respective cylinders of rotation which are in mutually intermeshing engagement to form said working zone and which are driven within a housing enclosing in substantial conformity the space occupied by the intermeshing cylinders of rotation of said working means, a pulp inlet at one longitudinal end of said shafts and a pulp outlet at the other longitudinal end of said shafts, said inlet and outlet communicating with said working zone, said working means comprising a plurality of radially directed axially spaced disks in mutually cooperative positions between said pulp inlet and said pulp outlet for compressive and kneading working of said pulp in said working zone between opposed surfaces of mutually intermeshing of said disks, the thickness of said disks diminishing towards the periphery thereof, means for rotating said shafts, and means positioned asymmetrically in relation to said opposed surfaces for causing pulp enclosed between said opposed surfaces to move in a direction towards said pulp outlet, said pulp-moving means comprising a plurality of guide rails each extending from an inner surface of said housing at a distance from said working zone and into the interspace between adjacent disks of the same shaft, said guide rails extending in a radial plane in relation to said shafts and being arranged in an asymmetric position in relation to opposed disks of the same shaft thereby to divert the pulp into a path leading to said pulp outlet.
