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.

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
