Screw Press Wastewater Treatment: Volute Dewatering Machine
It is composed of a volute dewatering body, filter device, sump, driving device, flocculation tank, and support frame. It is a new type of environmentally friendly, energy-saving and efficient sludge treatment equipment.
When the equipment is running, the sludge enters the filter cartridge from the feed port and is pushed by the screw shaft rotating blades to move to the discharge port. As the pitch between the screw shaft rotating blades is gradually reduced, the pressure on the sludge is also followed.
It 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. At the same time, the equipment relies on the self-cleaning function between the fixed plate and the movable plate to clean the filter gap to prevent clogging, and the mud cake passes through. After being fully dehydrated, it will be discharged from the discharge port under the push of the screw shaft.
