Internal Pressure Requirements and Self-Cleaning Process of Sludge Dewatering Machine

- May 09, 2018 -

During the operation, the main body of the stacking screw sludge dewatering machine is stacked on the fixed ring and the moving ring. In the operation, the screw shaft will effectively penetrate through the filter device, and the stacking screw sludge dehydrates. The front section of the machine is the enrichment section and the rear section is the dehydration section.

Stacked-flux sludge dewatering machine is effective to a certain extent, and its concentrated sludge will effectively move forward along with the rotation of its screw shaft. During operation, the screw pitch of the screw shaft will be along the exit direction of the mud cake. Gradually smaller, the gap between the ring and the ring also becomes smaller, and the volume of the spiral cavity shrinks.

Stacked screw sludge dehydration opportunity Under the action of the back pressure plate at the outlet, the internal pressure will gradually increase to a certain extent during operation. During operation, the spiral will effectively push the moving shaft to drive continuously under the continuous sludge. The moisture in the extrusion is discharged, and the solid content of the filter cake is continuously increased, and the continuous dewatering of the sludge is finally achieved.

During operation, the spiral screw sludge dewatering machine rotates the screw shaft to push the sludge from the enrichment section to the dehydration section. At the same time, it also continuously drives the moving ring to clean the filter joint to prevent clogging. When the screw pushes the shaft to rotate, the multiple fixed laminations disposed on the periphery of the pushing shaft relatively move. Under the action of gravity, water is filtered out from the gap of the relatively moving laminations to achieve rapid concentration.

The rotation of the screw shaft in the superfluous screw sludge dewatering machine can be continuously rotated by the ranger during the operation process, and the equipment will rely on the movement between the fixed ring and the traveling ring during the operation. To a certain extent, it is effective to achieve its continuous self-cleaning process, thus cleverly avoiding the common plugging problem of traditional dewatering machines.

Stacked screw sludge dewatering machine has been developed and popularized in China in recent years. In the process of using it, due to the features of easy separation and non-blocking during the operation of the equipment, such equipment has been widely used. In industrial wastewater treatment, municipal sewage treatment and pharmaceutical, textile, metallurgical and other industries.
