First, the sludge material is placed on the upper surface of the conveying belt 2. The conveying belt 2 transports the sludge material through the heating cavity 11 to dry the sludge material. Then the conveying belt 2 transports the dried sludge material into the lower part of the vertical baffle 4. The movable seat 51 vertically slides downward to contact the conveying belt 2. At this time, the dried sludge material is continuously transported into the forming space surrounded by the conveying belt 2, the vertical baffle 4, the movable seat 51 and the lateral pressing plate 52.

[0028] As a further embodiment of the present application, the movable seat 51 is provided with a chamfer to form a cutting part 511. The movable seat 51 is driven to vertically contact the upper surface of the conveying belt 2.

[0029] Specifically, as shown in Figure 2 , a chamfer is arranged on the movable seat 51 to form a cutting portion 511, when the movable seat 51 vertically slides to close the conveying belt 2, the cutting portion 511 moves close to and abuts against the upper surface of the conveying belt 2, that is, after the movable seat 51 vertically moves up to enable the block-shaped sludge material to be conveyed by the conveying belt 2 to the discharge port 12 for a certain distance, the movable seat 51 vertically moves down to enable the cutting portion 511 to cut the left end of the block-shaped sludge material to realize the segmentation of the sludge material on the conveying belt 2, thereby improving the discharge stability of the sludge material.
