The sludge dewatering machine consists of concentration section and dewatering section. After the sludge is concentrated by gravity in the thickening section, it is transported to the dewatering section. As the filter gap and screw pitch become smaller, also the block from back plate, internal pressure is generated and the sludge volume is continuously reduced, to make it fully dewatered.
1, Fixed and moving rings, secured by tie rods, stacked one by one with the screw shaft going through, form a filtering device.
2, The filter gap between fixed rings and moving rings, and the screw pitch become smaller and smaller from concentration section to dewatering section.
3, The rotation of screw shaft transports the sludge from concentration section to dewatering section, also drives the moving rings to clean the filter gap to prevent clogging.
4, The concentrated sludge is transported to dewatering section and moves forward with the screw shaft. While the filter gap and screw pitch become smaller, plus the block of baffle, a great internal pressure is generated to dewater the sludge.
