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

Apparatus for treating high concentration cellulose pulp having a consistency above the flowage limit, comprising two spaced shafts rotatable in the same axial plane, each shaft carrying a plurality of radially directed axially spaced disks located in mutually cooperative positions to define respective cylinders of rotation which are in mutually intermeshing engagement and form a working zone located between opposed surfaces of said disks in said mutually cooperative positions, the thickness of said disks diminishing towards the periphery thereof, said disks being located within a housing which closely conforms to the common cylinder of rotation space of said disks, said disks being positioned between 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 communicates with said working zone, means for rotating said shafts, 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 a asymmetric position in relation to opposed disks of the same shaft thereby to divert the pulp into a path leading to said pulp outlet, a first feeding screw thread carried by one of said shafts and being adjacent said inlet and extending from said inlet to said disks carried by said one shaft, and a second feeding screw thread carried by said other of said shafts and being adjacent said inlet and extending from said inlet to said disks carried by said other shaft, said first and second threads being oriented relative to each other for urging said pulp from said inlet towards disks.
