5 Minutes! Comprehensive Understanding Of Spiral Sludge Dewatering Machine
Sep 01, 2017

Spiral Sludge dewatering machine can be widely used in municipal wastewater treatment projects and petrochemical, light industry, chemical fiber, paper, pharmaceutical, leather and other industrial water treatment system. The actual operation proves that the screw-type sludge dewatering machine can create considerable economic and social benefits for customers.
Working principle:
1, concentration: When the spiral drive shaft rotation, the multiple solid-active laminations in the periphery of the driving shaft are relative moving, and under the action of gravity, the water is filtered out from the relative moving lamination gap to achieve rapid concentration.
2, dehydration: After the concentration of sludge with the rotation of the spiral axis moving forward; along the exit direction of the mud cake, the pitch of the spiral shaft becomes smaller gradually, the gap between the ring and the ring gradually becomes smaller, and the volume of the spiral cavity is shrinking; under the action of the back plate of the exit, the inner pressure is gradually enhanced, which is driven by successive running of the spiral drive The water in the sludge is squeezed out, the filter cake contains solids increasing continuously, and finally realizes the continuous dehydration of the sludge.
3, self-cleaning: Spiral shaft rotation, driving the swimming ring to rotate continuously, the equipment relies on the fixed ring and the moving ring between the movement realizes the continuous self-cleaning process, thus cleverly avoids the traditional dehydration machine common existence blockage question.
Construction principle:
The main body of the dewatering machine is composed of the fixed ring and the swimming ring, and the spiral axis penetrates into the filter device. The first part is the concentrated part, the latter part is the dehydration department.
The filter joint formed between the fixed ring and the swimming ring and the pitch of the helical shaft gradually become smaller from the thickening part to the dewatering part.
Spiral shaft rotation in the promotion of sludge from the concentration of the department to the dehydration department, but also continue to drive the swimming ring cleaning filter, prevent blockage.
Dewatering principle:
Sludge concentrated in the concentration of the Ministry of gravity after being transported to the dehydration department, in the process of advancing with the filter and pitch gradually smaller, as well as back plate blocking action, resulting in a great internal pressure, shrinking volume, to achieve full dehydration.
Product Advantages:
Widely used
1. Applicable to municipal sewage, food, beverages, chemicals, leather, welding materials, paper, printing and dyeing, pharmaceutical and other industries of sludge.
2. It is suitable for dewatering of high and low concentration sludge. When the low concentration (2000mg/l~) sludge is dehydrated, there is no need to build concentration ponds, storage ponds, reduce the construction cost, reduce the release of phosphorus and produce anaerobic odor.
