Type600 stainless steel fiber separator for the pulp cleaning
The fiber separator is a screening and pulping equipment with a
combination of disintegration, separation and screening functions
to remove various impurities in the waste paper raw materials by
utilizing the specific gravity difference between fibers and
impurities. The steel cone-shaped tank is a horizontal device. It
consists of continuous impeller separator, transmission mechanism
and slag discharge mechanism.
The slurry enters from the tangential pressure above the tank, and
the impeller functions as a pump. The slurry generates axial
circulation and the fiber separation bottom knife fixed by the
impeller peripheral device, which not only promotes fiber
separation, but also generates vortex washing screen holes. The
good pulp is sent out through the sieve pressure of the sieve plate
on the back of the impeller.
Light impurities such as plastic are concentrated in the center due
to the eddy current effect, and a part of the slurry is regularly
discharged from the center outlet of the front cover. Heavy
impurities are driven by the centrifugal force along the conical
groove and discharged through a short spiral channel into the lower
sediment opening. The fiber separator is generally used as a
secondary pulp and separation equipment after the hydraulic pulper.
Its characteristics are:
1. It has three basic functions, such as second dissolving of
slurry, separation of light impurities, and removal of heavy and
coarse waste.
2. The pulping process of the fiber separator can use low-level
waste paper, which can reduce the pretreatment of raw materials and
reduce costs.
3. The pulping process of the fiber separator can increase the
production capacity of the existing hydraulic pulper and save
10-20% of the unit energy consumption.
4. The pulping process of the fiber separator can obtain
high-quality pulp with less fiber loss.

The impeller separator consists of an impeller, a separation bottom
knife, a sieve plate, a slurry receiving groove, and a transmission
mechanism.
The impeller is designed as an open turbine with curved fins. The
vane has a leading angle. When the impeller rotates, the liquid
discharge is large, the circulation rate is increased, and a strong
centrifugal effect is generated. It can also push light impurities
to the center outlet of the front cover. The impeller is made of
cast stainless steel.
The fixed fiber separator bottom knife is installed around the
impeller, and the gap between the impeller and the impeller is
adjusted by bolts.
The sieve plate has a full-sorting structure, and the sieve hole
specifications are Φ2.5, Φ3, Φ4, and Φ5.
Φ4 is the standard specification.
The impeller separator adopts a V-belt transmission and a
double-fulcrum combined bearing structure. The bearing support is
composed of a slurry receiving trough and a trough body, which are
respectively carried on the cement foundation.
The cone groove is made of steel plate welding, there is a
tangential slurry inlet at the top, a spiral groove slag discharge
bucket below, a tapered front cover with a scum discharge outlet,
the front cover is fixed to the groove with bolts, and is equipped
with a hinge structure To be used for cleaning and maintenance.
