[0044] In the embodiment, the drying space 110 for drying sludge is arranged in the frame body 100. The sludge is conveyed to the drying space 110 through the inclined slide 200. The first screen 210 located at the one end of the inclined slide 200 close to the drying space 110 can filter the sludge. The sludge can pass into the drying space 110 through the first through -hole 211, and the larger solid is blocked on the screen. The lever 310 can rotate relative to the frame body 100. When the lever 310 rotates, it can pass through the second through -hole 222, so as to stir the solid on the first screen 210.

[0045] The first screen 210 can effectively screen the solid impurities in the sludge before the sludge enters the drying space 110, reducing the risk of blockage in the subsequent conveying and processing process. Secondly, the setting of the lever 310 can timely clean the solid impurities on the screen, avoid the screen from being blocked, and ensure the continuous filtration. Furthermore, the lever 310 can produce a patting effect on the larger sludge on the first screen 210, improve the passing rate of the sludge, improve the working efficiency and stability of the sludge heat pump drying all -in -one, and reduce the failure and downtime caused by the solid impurities.
