Sludge dewatering device applied to urban river channel cleaning

The utility model relates to the technical field of mechanical dehydration of sludge, and particularly discloses a sludge dehydration device applied to urban river cleaning, which comprises a box body, a feed port and a discharge port are arranged on the box body, at least one pair of filter pressing drums is arranged in the box body, a filter layer is sleeved outside the filter pressing drums, and the filter pressing drums are arranged in the box body. A plurality of through holes are formed in the filter pressing drum in the radial direction, and a water receiving part is arranged in the filter pressing drum. Sludge is squeezed and dehydrated by the two filter pressing rotary drums which are oppositely arranged, water flows into the filter pressing rotary drums along the through holes and is collected and discharged by the water receiving component, and the squeezed sludge flows to the discharge port along the material guide plate. According to the sludge squeezing and dewatering device, squeezed sludge and
