Stacked snail sludge dewatering machine

Availability:

1. Working principle

When the equipment is running, the sludge enters the filter cartridge from the feed port and is pushed by the screw shaft and moves to the discharge port. The filter cartridge is a filter device in which a fixed ring and a movable ring are stacked on each other, and the spiral shaft runs through the stroke of the filter device. The front section is the concentration section, and the rear section is the dehydration section. As the pitch between the spiral blades gradually shrinks, the pressure on the sludge continues to increase, and dehydration starts under the action of the pressure difference. The water flows out from the filter gap between the fixed ring and the movable ring, and the equipment depends on The automatic cleaning function between the fixed ring and the movable ring cleans the filter gap to prevent clogging. The mud cake is discharged from the discharge port under the push of the screw shaft after sufficient dehydration.

2. Product structure

The main body of the stacked screw is a filter device in which a fixed ring and a movable ring are stacked on each other to form a cylinder, and the spiral shaft runs through the stroke. Because the outer diameter of the screw shaft is larger than the inner diameter of the movable ring, the rotation of the screw shaft drives the movable ring to make a circular motion to prevent blockage. The gap between the fixed ring and the movable ring gradually becomes smaller along the direction of the mud cake outlet from the thickening part to the dewatering part. After the sludge is concentrated by gravity in the thickening section, it is transported to the dehydration section, where it is forced to be dehydrated under the action of the internal pressure generated by the back pressure plate at the discharge outlet.
