PROBLEM TO BE SOLVED: To provide a solid-liquid separation device capable of preventing damage of the revolving shafts while inhibiting the weight increase of the revolving shafts and lamination-shaped rotational filtering bodies.SOLUTION: A solid-liquid separation device 100 comprises: revolving shafts 11; lamination-shaped rotational filtering bodies 1 including a plurality of large-diameter disc filtering pieces 14, small-diameter disc filtering pieces 13, and middle-diameter disc filtering pieces 12 laminated along the revolving shafts 11; and a motor 2 rotation-driving the revolving shafts 11. The lamination-shaped rotational filtering bodies 1 are arranged in two-rowed shape toward a solid discharge port 6 and include lamination-shaped rotational filtering bodies 1e, 1f, 1j, and 1i arranged at a solid discharge port 6 side. Besides, the motor 2 includes: motors 2e, 2j provided at one side of the revolving shafts 11 of the lamination-shaped rotational filtering bodies 1e, 1j in a shafting direction; and motors 2f, 2i provided at the other side of the revolving shafts 11 of the lamination-shaped rotational filtering bodies 1f, 1i in the shafting direction. |
