When the screw rises, the filter cloth mounting plate is raised, making the filter cloth cylinder form an annular sludge receiving tank. Sludge is loaded into the sludge receiving tank, and the water in the sludge is drained through the filter cloth cylinder. The electric heating tube is energized to dry the sludge. The up-and-down movement of the screw causes the sludge in the filter cloth cylinder to tumble, which promotes the drainage of water from the sludge and ensures that the sludge is heated evenly. After the sludge is dried, the screw descends, lowering the filter cloth mounting plate to its lowest point. At this time, the filter cloth cylinder is in the shape of a trumpet, and the sludge in the filter cloth cylinder falls into the discharge funnel through the discharge port on the filter cloth mounting plate and is discharged.
