Horizontal Sludge Dewatering Centrifuge Machine Sludge Decanter
Deslimer
Product Description:
Sludge centrifugal dehydrator is a machine that uses the principle
of centrifugal sedimentation to concentrate or dewater sludge. It
consists of a rotating drum, screw conveyor, differential, main
bearing, bottom frame, liquid and solid phase collection chamber,
upper cover, motor transmission device, frequency converter and
other components.
Working Principle:
After the sludge is fed into the drum through the hollow rotating
shaft, it is immediately thrown into the drum cavity under the
action of centrifugal force generated by high-speed rotation. Due
to the high density and high centrifugal force, the sludge
particles are thrown onto the inner wall of the drum to form a
solid ring layer; due to the low density and small centrifugal
force of the water, the liquid ring layer can only be formed inside
the solid ring layer. The sludge in the solid ring layer is
transported to the cone end of the drum under the slow push of the
screw conveyor, and is continuously discharged through the outlets
around the drum; the liquid in the liquid ring layer is
continuously "overflowed" from the weir to the drum. outside,
forming a separated liquid, which is then collected and discharged
out of the dehydrator by gravity.
Process Flow:
The precipitated sludge from the sludge concentration tank is
crushed by the sludge cutting machine and transported by the sludge
feed pump. After being measured by the electromagnetic flowmeter,
it is combined with the prepared chemical liquid sent by the
flocculant dosing system. Mix and enter the centrifugal dehydrator;
the sludge is separated into solid/liquid phases by the dehydrator,
and the liquid phase is directly discharged or returned to the
sedimentation tank.
In the automatic dosing system of flocculant, powdery flocculant is
added from the hopper (material feeder) and added to the
preparation tank by the automatic powder feeding device. Tap water
enters the preparation tank through the flow meter and is
automatically prepared into a solution of a certain concentration;
preparation The solution in the pool flows into the storage tank
and is transported by the dosing screw pump. After being measured
by the electromagnetic flowmeter, it is mixed with the sludge from
the sludge concentration tank through the manifold (or static
mixer) and the high-speed rotation of the centrifuge. The
centrifugal force causes the dense materials (solid phase) in the
suspension entering the drum to settle and separate under the
action of centrifugal force and centrifugal fluid pressure, and
then enter the dewatering machine together for sludge dehydration.
