Brief introduction of the application of the stacked screw sludge dewatering equipment
- 2020-11-16-

The stacked screw sludge dewatering machine has a wide range of applications, such as petroleum, municipal administration, chemical industry, breeding, textile printing and dyeing. It can be used for many types of working sewage. The product has a long service life, small footprint, convenient repair, low operating cost, and can complete automatic operation for 24 hours. At the same time, the feature of low concentration treatment makes the equipment reduce the amount of sludge. Relying on storage pool (thickening pool).

The main body of the stacked screw sludge dewatering machine is a filtering device composed of a fixed ring and a movable ring stacked on each other to form a cylinder, and a screw shaft penetrates between them. Because the inner diameter of the screw shaft is larger than the inner diameter of the traveling ring, the rotation of the screw shaft drives the traveling ring to make a circular motion to avoid blocking. The open space between the fixed ring and the movable ring is along the direction of the mud cake outlet. The spiral sludge dewatering machine manufacturer gradually becomes smaller from the thickening section to the dewatering section. The sludge is concentrated in the thickening section and transported to the dewatering section. Forced dehydration is achieved under the action of the internal pressure of the pressure plate at the outlet.

1. Concentration of sludge dewatering machine: When the screw pushing shaft rolls, the multiple solid and living laminations arranged on the periphery of the pushing shaft move relatively. Under the action of gravity, water is filtered out from the relatively moving laminations to complete the concentration.

2. Dewatering by the sludge dewatering machine: The concentrated sludge moves forward with the tumbling of the screw shaft; along the direction of the mud cake outlet, the screw pitch of the screw shaft gradually decreases, and the space between the rings gradually decreases. The volume of the spiral cavity is constantly shortening; under the action of the back pressure plate at the outlet, the internal pressure gradually increases. Under the continuous operation of the screw shaft, the water in the sludge is squeezed out, and the solid content of the filter cake continues to increase. , And finally complete the continuous dewatering of the sludge.

3. Self-cleaning of the sludge dewatering machine: the rotation of the screw shaft pushes the moving ring to continuously roll. The equipment relies on the movement between the fixed ring and the moving ring to complete the continuous self-cleaning process, thus miraculously avoiding the ubiquity of traditional dewatering machines. The blocking problem.
