In recent years, laminated sludge dewatering machine has been developed rapidly in China. Innovation and popularization, due to the easy separation and non-clogging characteristics of the laminated sludge dewatering machine, has been widely used in municipal sewage treatment and industrial wastewater treatment, petrochemical, pharmaceuticals, textiles, metallurgy, food and beverage, mines and many other fields.
The stack screw dewatering machine has the advantages of saving water, saving electricity, high automatization and continuous operation, and has a unique advantage in the farming wastewater treatment industry.
Working principle stack screw dewatering machine
Thickening: When the spiral drive shaft rotates, the multiple solid-live overlapping slices are arranged in the driving shaft periphery relative to move, under gravity, the water is filtered out of the relative moving overlapping gap and realizes fast enrichment.
Dehydration: The concentrated sludge is moving forward continuously with the rotation of the spiral shaft; along the direction of the mud cake outlet, the screw pitch gradually becomes smaller, the gap between the rings and the rings becomes smaller. The volume of spiral cavity is shrinking continuously, the internal pressure is gradually strengthened under the effect of the back plate of the outlet, and the moisture in the sludge is pressed and discharged by pressing the axial continuous operation of the spiral, and the filter cake contains the steady increase of the solid amount, and finally realizes the continuous dewatering of the sludge.
Self-Cleaning: Rotation of the spiral shaft, driving continuous rotation of the moving rings, the equipment relies on the movement between the stationary rings and the swimming rings to achieve continuous self-cleaning process, thus subtly avoiding the widespread blockage problem of the traditional dehydration machine.
Sludge concentrated in the concentrated part after gravity, transported to the dehydration department, in the process of advancing with the gradual change of filter and pitch smaller, as well as the blocking of the back plate, resulting in a tremendous internal pressure, the volume is shrinking, to achieve full dehydration purposes.
Applicable to municipal sewage, food, beverage, chemical, leather, welding materials, papermaking, printing and dyeing, pharmaceutical and other industries sludge.
Suitable for the dehydration of high and low concentration sludge. When the low concentration (2000mg/L~) sludge is dehydrated, it is not necessary to construct the concentrated pool, storage pool, reduce the construction cost, reduce the release of phosphorus and the production of anaerobic odor.
Compact design, the dehydration machine contains the electric control cabinet, metering trough, flocculation mixing trough and dehydration machine main body. Stack screw dewatering Machine
Small footprint, easy to repair and replacement, small weight, easy to carry.
The function of self cleaning. Do not need to prevent the blockage of filter cleaning, reduce flushing water consumption, reduce the internal circulation burden.
Good at dehydration of oily sludge.
