The utility model relates to the technical field of dredged
soil treatment equipment, in particular to dredged soil
dewatering and
drying equipment, which comprises a base, a
drying device and a feed hopper, and further comprises a screening device arranged below the feed hopper, comprising a screening box, a supporting frame installed in the screening box through an elastic supporting piece, a
vibration motor arranged at the bottom of the supporting frame, a screen and a water filtering plate, wherein the screen and the water filtering plate are vertically distributed on the supporting frame. And the
extrusion dewatering device is arranged below the screening device and comprises an
extrusion cylinder fixed to the base, a water filtering cylinder concentrically arranged in the
extrusion cylinder, an extrusion screw rotationally installed in the water filtering cylinder and a first driving motor for driving the extrusion screw, and the end of the water filtering cylinder is connected with the
drying device. The screen and the water filtering plate in the screening device are distributed up and down, so that water can be quickly discharged through the screen and the water filtering plate while the dredged soil is preliminarily screened, preliminary
dehydration is realized, and the
water content of the dredged soil entering a subsequent extrusion
dehydration device is reduced.
