The utility model provides a high-efficiency dewatering elliptic overlapped solid-liquid separation device which comprises a natural dewatering section and a squeeze dewatering section. The natural dewatering section and the squeeze dewatering section each comprise a plurality of rotating shafts which are distributed in the processed object conveying direction side by side and can be driven by a driving piece to rotate around the axes in the same direction at the same speed, a plurality of rotating plates which are fixedly arranged on the rotating shafts in a sleeving mode, and a plurality of rotating plate arrays which are fixedly arranged at the same positions of the different rotating shafts in a sleeving mode and formed by overlapping a plurality of rotating plates, wherein diversion plates are arranged between every two adjacent rotating plate arrays. Drainage gaps are formed between every two adjacent diversion plates. The rotating plates are elliptical, the eccentricity of each rotating plate ranges from 0.3 to 0.9, the length of a semi-major axis of each rotating plate ranges from 50 mm to 90 mm, the thickness of each rotating plate ranges from 3 mm to 7 mm, and the lengths of the gaps between every two adjacent rotating plates of each rotating plate array each range from 4 mm to 9 mm. By means of the high-efficiency dewatering elliptic overlapped solid-liquid separation device, the conveying efficiency and dewatering efficiency of processed objects can be improved.
