The Spiral Stacking Sludge Dewatering Machine

JX Filtration December 19, 2024 Screw Press

Structural composition:

1.Fixed ring and floating ring: stacked on each other to form a filter chamber, and the pitch gradually decreases from the concentration part to the dewatering part.
2.Spiral shaft: runs through it, with spiral blades on the surface to push the sludge forward.
3.Drive device: provides power to rotate the spiral shaft.

Working principle:

1.Concentration stage: Under the action of gravity, the sludge is filtered out of the gap through the relative movement of the fixed ring and the floating ring, and rapid concentration is achieved.
2.Dehydration stage: The concentrated sludge moves forward continuously with the rotation of the spiral shaft, the pitch and the ring gap gradually decrease, the internal pressure increases, the water is squeezed out, and finally continuous dehydration is achieved.
3.Self-cleaning function: The rotation of the spiral shaft drives the floating ring to clean the filter seam, prevent blockage, and reduce the amount of water used for flushing.

Advantages and characteristics:

1.Efficient energy saving: It can quickly and effectively separate solids and liquids, and the energy consumption is low during operation.
2.Simple operation: high degree of automation, can achieve 24-hour fully automatic operation, reducing manual operation.
3.Small footprint: compact design, easy to install and maintain.
Environmental protection and sanitation: closed operation to avoid secondary pollution.

Application range:

Widely used in municipal sewage treatment, petrochemical, light industry, paper making, pharmaceutical and other industries, suitable for dehydration of high and low concentration sludge
