Inflow Pressure Screen
Inflow Pressure Screen is advanced paper pulp screening equipment in the modern world,
which has great ability of screening function and low pulse. It is
widely used in the fine screening of wood pulp, straw pulp and
waste paper pulp, especially suitable as the net filter before
paper machine.
Inflow Pressure Screen is a continuing screening equipment under the fully closed
position with pressure. When works, the pulp enters into the
outside of screen drum along the tangent direction through the pulp
pipe. Qualified pulp enter into screen drum through the sieve seam
(hole), with the help of pressure difference between inside and
outside of screen drum, then come out through the pulp pipe. The
pulp and impurities which can not through the sieve seam (hole)
fall down to the bottom, and come out from the discharge pipe.
Rotating blade outside the screen drum can produce a moderate
pressure, which improves the circulation flow of pulp, its tail
will produce a negative pressure, which has an effect of backwash
sieve seam (hole). It can prevent the sieve seam (hole) congestion,
and pulp can smooth enter through the sieve screening (hole) from
the surface constantly, which ensures the continuous operation.
