Brief introduction: The stacked screw sludge filter press dewatering machine is suitable for sludge from various industries such as municipal sewage, domestic sewage, food, beverage, chemical, leather, welding materials, papermaking, printing and dyeing, pharmaceuticals, electroplating, oil fields, coal mines, brewing, animal husbandry, kitchen wastewater, water plants, power plants, steel plants, etc.

Stacked screw sludge dewatering machine

Structural principle

The main body of the stacked spiral sludge dewatering machine is a filtering device formed by stacking a fixed ring and a moving ring, with a spiral shaft passing through it.
The small movable filter gap formed between the fixed ring and the moving ring filters the filtrate, and the inner cavity formed by the spiral shaft and the ring plate is filled with flocculent particles,
Convey compression and form mud cake during the rotation process of the end back pressure plate.
The spiral shaft rotates and drives the moving ring up, down, left, and right to clean the filter gap and prevent blockage.

Dehydration principle

After gravity concentration in the thickening section, the sludge is transported to the dewatering section. As it moves forward, with the gradual reduction of the filter gap and pitch, as well as the blocking effect of the back pressure plate, a large internal pressure is generated, and the volume continuously decreases, achieving the goal of full dewatering.
