8m3/h Stainless Steel 304 screw press sludge dewatering machine for
Industrial Wastewater Treatment
The sludge dehydrator dewaters the sludge through the screw
extrusion principle. The sewage added with flocculant enters the
filter cylinder and is pushed forward by the screw shaft. Under the
pressure, the water is filtered out from the gap between the
high-precision fixed spiral and the movable spiral, and the sludge
cake is squeezed forward to achieve the dehydration effect. High
filtration accuracy, automatic whole process without labor and
consumables, and good long-term operation stability, suitable for
sewage purification of breeding farms, slaughterhouses, domestic
sewage, printing and dyeing paper, medical wastewater, sewage
treatment plants, etc.
Working Principle
When the equipment is running, the sludge enters the filter
cartridge from the feed port and is pushed to the discharge port by
the spiral blades. As the screw pitch of the spiral shaft gradually
decreases, the pressure on the sludge also increases, and the
sludge begins to dehydrate under the effect of the pressure. The
water flows out from the gap between the fixed ring and the movable
ring. At the same time, the equipment relies on the self-cleaning
function between the fixed ring and the movable ring to clean the
filtering gap, which is not easy to block, The sludge cake is
discharged from the discharge port under the propulsion of the spiral shaft after dehydration.
Structure Introduction
1,Metering tank The sludge is transported to the metering tank
through the sludge transfer pump, and the excess part is returned
to the sludge storage tank from the return pipe .
2,Flocculation mixing tank The metered sludge is fully mixed with
the injected polymer flocculant in the flocculation mixing tank to
form a good alum flower.
3,Dehydration body After the sludge enters the dehydration body
through the sludge inlet, gravity concentration occurs
instantaneously in the concentration section of the front section,
most of the filtrate is discharged, and the dehydration section is
fully dewatered due to the continuous rise of the internal chamber
pressure.
4, Sludge outlet/concentrated sludge discharge Make the sludge more
fully dewatered and discharge from the sludge outlet in the form of
sludge cake. The sludge thickener discharges concentrated sludge
through the sludge outlet, and no back pressure plate is set at the
sludge outlet side of the sludge thickener.
