Title:
SLUDGE DRYER
Document Type and Number:
WIPO Patent Application WO/2022/105089
Kind Code:
A1
Abstract:
The invention relates to a sludge dryer, comprising a drying cylinder, a main shaft arranged in the drying cylinder, a screw blade spirally wound around the main shaft in an axial direction, and a driving mechanism for driving the main shaft to rotate. Both ends of the drying cylinder are respectively provided with a feeding port and a discharging port, and the drying cylinder is vertically arranged. The main shaft is vertically arranged at a central position of the drying cylinder, and an axially penetrating extrusion hole is formed in the screw blade. During the upward conveying process of the screw blade, wet sludge is extruded to the lower part through the extrusion hole under an extrusion action, and a crushing assembly is arranged at the upper end of the drying cylinder. According to the present invention, extrusion holes are formed in the screw blade, so that sludge with higher water content is extruded to the lower part during a screw conveying process and circularly moves in an up-and-down direction in the drying cylinder until the sludge is dried, thereby achieving the effect of stirring of sludge, fully drying sludge, and improving drying efficiency.
