Patent

CA 2092437

A method and apparatus for enhan- cing knot transport in a knot drainer has a provision for decreasing tangential veloci- ty of the feed slurry in the inlet chamber (10), a hydrodynamic force reduction pro- vision in the screening chamber (20), and a provision for increasing the ratio of cir- cumferential friction forces to axial fric- tion forces in a housing extension (40) above the screening chamber (20). This drastically reduces frequency of knot transport interruptions which would other- wise occur in the knot drainer, thereby im- proving knot drainer performance efficien- cy.
