screw press sludge dewatering equipment Manufacturer automatic volute dewatering machine
The screw stacking main body of the dehydrator is a filtering device formed by the overlapping of the fixed ring and the traveling ring, and the spiral shaft runs through it. The front section is the concentration section, and the rear section is the dehydration section.
The filter gap formed between the fixed ring and the traveling ring
and the screw pitch of the spiral shaft gradually decrease from the
concentration section to the dehydration section.
The rotation of the spiral shaft drives the sludge to be
transported from the thickening section to the dewatering section,
and also drives the traveling ring to clean the filter seams to
prevent clogging.
Concentration
When the spiral drive shaft rotates, the multiple solid and movable
laminations arranged at the periphery of the drive shaft move
relatively. Under the action of gravity, water is filtered out from
the relatively moving lamination gap to achieve rapid
concentration.
Dewatering
The thickened sludge moves forward with the rotation of the spiral
shaft; Along the outlet direction of the mud cake, the screw pitch
of the spiral axis gradually decreases, the gap between rings also
gradually decreases, and the volume of the spiral chamber
continuously shrinks; Under the action of the back pressure plate
at the outlet, the internal pressure gradually increases. Under the
continuous operation of the spiral drive shaft, the water in the
sludge is squeezed out, and the solid content of the filter cake
continues to increase, finally realizing the continuous dehydration
of the sludge.
Self cleaning
The rotation of the spiral shaft drives the traveling ring to
rotate continuously. The equipment realizes a continuous
self-cleaning process by relying on the movement between the fixed
ring and the traveling ring, thereby ingeniously avoiding the
common blockage problem of traditional dehydrators.

Real picture
Product features
Wide application
sludge dewatering machine is applicable to sludge in municipal
sewage, food, beverage, chemical industry, leather, welding
materials, paper making, printing and dyeing, pharmaceutical and
other industries.
sludge dewatering machine is suitable for dehydration of high and low concentration sludge.
When the sludge with low concentration of 2000mg/L is dewatered,
there is no need to build a thickening tank and a storage tank, so
as to reduce the construction cost, phosphorus release and
anaerobic odor generation.
Small design
The design is compact, and the dehydrator contains an electric
control cabinet, a metering tank, a flocculation mixing tank and
the main body of the dehydrator.
Small floor space, convenient for maintenance and replacement;
Small weight, easy to carry.
Not easy to block
spiral dewatering equipment has the function of self-cleaning. spiral dewatering equipment is not necessary to clean to prevent the filter seam from clogging, reduce the water consumption for flushing and reduce the burden of internal circulation. Good at dewatering oily sludge.
Low speed operation
The rotating speed of the spiral shaft is about 2~3r/min, and the
electrode consumption is low.
Less faults, low noise and vibration, safe operation.
Simple operation
Through the electric control cabinet, it can be linked with the
medicine bubbler, mud pump, dosing pump, etc. to achieve 24h
continuous unmanned operation.
The daily maintenance time is short and the maintenance operation
is simple.
Durable
The body is almost made of stainless steel, which can maximize the
service life.
Only the spiral shaft and traveling ring are replaced, so the
service cycle is long.
Cost reduction of design, construction and operation
The product specifications are diverse and the series are complete.
For different processing scales, the most appropriate model can be
selected to avoid overuse of talents.
The machine body is compact in design and integrated in
concentration and dewatering. It is equipped with electric control
cabinet, sludge flocculation mixing tank and other auxilia
