The above are all prior arts, which are well known to the staff in this field, so they will not be described in detail. However, in the present invention, a material receiving component 4 is arranged under the mud discharge plate 3. Before use, the dredging component 5 is adjusted to establish a connection between the dredging component 5 and the inside of the mud discharge plate 3, so that when the material is discharged, the dredging component 5 is started to stir the inside of the mud discharge plate 3, thereby achieving an anti-blocking effect, thereby effectively preventing excessive sludge discharge, clogging the mud discharge plate 3, causing sludge reflux, affecting dehydration, and reducing the dehydration capacity.

[0032] After the sludge is discharged into the material receiving component 4, it will be dried and filtered first, and then the pushing mechanism 6 can be started to squeeze the sludge to fully dehydrate the water inside the sludge to improve the dehydration effect of the dehydration device. At the same time, the material receiving component 4 is used to facilitate the centralized collection and treatment of the sludge.

[0033] Further, the material receiving assembly 4 includes a fixed frame 401, a material receiving box 402 is provided on the lower surface of the fixed frame 401, a water storage tank 403 is provided on the lower surface of the material receiving box 402, the fixed frame 401, the material receiving box 402 and the water storage tank 403 are interconnected, and a filter plate 406 is provided between the material receiving box 402 and the water storage tank 403;

[0034] Specifically, Figure 2 and Figure 4 As shown, after the sludge is discharged from the sludge outlet plate 3, the sludge will fall onto the filter plate 406 in the receiving box 402 for drying, and the sludge will be filtered. The filtered sewage will flow into the water storage tank 403 for collection, thereby achieving dehydration during the sludge collection process to improve the dehydration effect.

[0036] Specifically, Figure 2 and Figure 4 As shown, after a certain amount of sludge is discharged, the cylinder 601 can be started to drive the push plate 602 to slide to one end on the filter plate 406, so that the sludge is pushed toward the sealing plate 404, the sludge is squeezed, and the sludge is dehydrated again, so that the sludge is fully dehydrated, and then the limit bolt 405 is removed, and the sealing plate 404 is removed from one side of the material receiving box 402 to take out the sludge, thereby achieving the effect of convenient removal.
