After the L-shaped push plate 16 moves forward, the rectangular hole 17 in the upper part of the L-shaped push plate 16 is closed by the inner top of the storage cabin 9, so that the sludge cannot leak out and can only be discharged from the rectangular discharge port 21.

[0032] Specifically, the working principle of the sludge drying device is as follows: the conveying belt frame 2 and the soft heating plate 5 are started to rotate, the sludge is put into the storage cabin 9, and then the L-shaped push plate 16 is pushed by the hydraulic push rod 11 to extrude the sludge in the storage cabin 9, so that the sludge is discharged from the rectangular discharge port 21 below the storage cabin 9 to the upper part of the soft heating plate 5. The sludge extruded from the rectangular discharge port 21 is in the form of thin slices, which is more convenient for drying. The dried sludge is separated from the upper part of the soft heating plate 5 and crushed by the mud lifting plate 8, and then transported to a designated position. The thin sludge is dried, which not only has good drying effect but also has high drying efficiency, thereby reducing energy consumption. The sludge is further dried and heated by the soft heating plate 5 to reduce the water content in the sludge. The dehumidifying heat exchanger 6 on the upper part of the covering box 3 can treat the water vapor generated during the drying of the sludge and recycle the heat, thereby reducing energy consumption.
