Brief description of the principle of volute sludge dewatering machine Sep 30, 2017

Volute sludge dewatering machine can be widely used in municipal sewage treatment works and petrochemical, light industry, chemical fiber, paper, pharmaceutical, leather and other industrial industries water treatment system. The actual operation proved that the volute sludge dewatering machine for customers to create considerable economic and social benefits.
Working principle of volute sludge dewatering machine
1, the concentration: When the spiral drive shaft rotation, located in the drive shaft around the multiple solid laminated stack relative movement, under the action of gravity, the water from the relative movement of the gap in the filter to achieve rapid concentration.
2, dehydration: the concentration of sludge along with the rotation of the screw shaft continue to move forward; along the direction of the export of the cake, the screw shaft pitch gradually smaller, ring and ring between the gap is gradually smaller, the spiral cavity volume The pressure in the sludge is squeezed and discharged, and the solid content of the cake is continuously increased, and finally the sludge is finally realized. Continuous dehydration.
3, self-cleaning: the rotation of the screw shaft to promote the continuous rotation of the swimming ring, the device relies on the movement between the fixed ring and the swimming ring to achieve a continuous self-cleaning process, which cleverly avoid the conventional dewatering machine common problems.

Tectonic principle of volute sludge dewatering machine
The main body of the dewatering machine is a filter device in which the fixed ring and the swimming ring are laminated with each other and the screw shaft is formed, and the front section is a concentrated part and the latter part is a dehydration section.
The pitch between the retaining ring and the screw shaft formed between the fixed ring and the swim ring is gradually reduced from the concentration portion to the dehydration portion.
Rotation of the screw shaft in the promotion of sludge from the condensate to the Department of dehydration at the same time, but also continue to drive the swimming ring cleaning filter to prevent clogging.

Dehydration principle of volute sludge dewatering machine
After the sludge is concentrated in the concentrated part, the stacking machine is transported to the dehydration section. As the filter and the pitch gradually become smaller, and the back pressure plate is stopped, the internal pressure is generated, Volume continues to shrink, to achieve the purpose of adequate dehydration.
