Continuous deep sludge squeezing and deep dewatering device

The invention provides a continuous deep sludge squeezing and deep dewatering device, and relates to the technical field of sludge treatment. The invention provides a continuous deep-squeezing sludge deep-dewatering device. The continuous deep-squeezing sludge deep-dewatering device comprises two stages of high-pressure pre-squeezing dewatering and deep-squeezing dewatering. In the high-pressure pre-pressing dehydration stage, the sludge with high water content is pre-extruded to remove part of water by virtue of the cooperation of an upper-layer filter belt assembly and a lower-layer filter belt assembly, and then the pre-extruded and dehydrated sludge is gradually transited to the deep pressing dehydration stage in batches by virtue of an adjusting box. The sludge subjected to pre-extrusion dewatering is subjected to deep water pressing treatment through a deep squeezing assembly on the conveying belt, and then deep dewatering is completed. The sludge deep dehydration device can realize continuous and super
