The utility model discloses a paper pulp
rotational flow high concentration desander relates to
papermaking equipment technical field, the paper pulp
rotational flow high concentration desander includes feed tee joint, pulp outlet
pipe, conical liner, shell and
sediment tank, feed tee joint's pulp
inlet channel is arranged along feed tee joint's side wall tangential direction, feed tee joint's
barrel inner wall is fixed with the
helical blade that is distributed along the axial direction, feed tee joint's
barrel inner wall is fixed with feed tee joint's feed tee joint's
barrel inner wall is fixed with feed tee joint's feed tee joint's feed tee joint's feed tee joint's feed tee joint's feed tee joint's feed tee joint's feed tee joint's barrel inner wall. The spiral blades surround the circumferential direction of the
slurry outlet
pipe arranged in the axial direction, the inner wall of the feeding three-way barrel, the spiral blades and the
pipe wall of the
slurry outlet pipe define a spiral downward flow guide channel, the rotating direction of the flow guide channel is consistent with the
cut-in direction of the
slurry inlet channel, and conical spiral edges distributed in the axial direction are fixed to the inner wall of the conical container. The spiral blades, the flow guide channel and the conical spiral edges are arranged, slurry flows down along the flow guide channel after entering the sand remover in the tangential direction, the stability of
rotational flow is improved, the slurry with stable rotational flow enters the conical container and is guided by the conical spiral edges, the
inertia of
centrifugal force and the stability of the direction are kept, and stable separation of impurities and the slurry is guaranteed.
