The function and volume shrinkage of volute sludge dewatering machine

Mar 10, 2018

The rotation of the screw shaft of the superfluous volute sludge dewatering machine promotes the transport of sludge from the enrichment section to the dehydration section, and at the same time, it constantly drives the traveling ring to clean the filter joint to prevent clogging. The sludge is concentrated in its concentrated area and transported to the dewatering department.

In the process of advancement, the superfluous volute sludge dewatering machine will gradually decrease with the filter joint and the pitch. Under the action of the back pressure plate of the equipment, it will generate its enormous internal pressure, and the volume will continue to shrink to reach fullness. The purpose of dehydration.

Volute sludge dewatering machine work flow chart

1. When the spiral screw sludge dehydration machine is running, when the screw pushes the shaft to rotate, the multiple solid laminations set on the periphery of the thrust shaft need to move relative to each other. Under the action of gravity, the water is filtered out from the gaps of the relatively moving laminations. Achieve rapid concentration.

2. After the concentrating sludge of the conglomerate spiral sludge dewatering machine moves forward with the rotation of its screw shaft, it will follow the mud cake exit direction in the operation, the pitch of the screw shaft will gradually become smaller, and the ring and ring The gap between them also gradually becomes smaller, and the volume of the spiral cavity shrinks.

Volute sludge dewatering machine under the effect of the back pressure plate at the outlet, its internal pressure will gradually increase, the equipment in the spiral push shaft in order to promote continuous operation, the water in the sludge squeezed out, its filter cake contains The solid volume keeps rising, and finally the continuous dewatering of the sludge is achieved.
