Rapid dewatering device for dredged sludge

The invention discloses a rapid dewatering device for dredged sludge. The sludge conveying pipeline is used for conveying sludge, the water storage tank is located below the sludge conveying pipeline, the sludge removing pipeline extends out of the bottom of the water storage tank from the interior of the water storage tank, and a flexible filtering device used for twisting, extruding and dewatering the sludge is connected between the sludge conveying pipeline and the sludge removing pipeline. The flexible filtering device is located in the water storage tank and can enable the flexible filtering device to dehydrate the sludge through torsion and extrusion, meanwhile, water generated in the dehydration process directly falls into the water storage tank, and hardened sludge generated after dehydration is discharged out of the sludge removal pipeline. After the structure is adopted, the whole structure is compact, the occupied space is small, the dehydration process is simple and rapid, the dehydration rate is
