PROBLEM TO BE SOLVED: To provide a vertical screw press type filter device: where filtration efficiency and concentricity with a ribbon screw can be kept, by ensuring sufficient fitting rigidity without being restricted by the size and number of an opening hole and the like, in an inside filter body forming a filtration space to house a ribbon screw; and which is excellent in maintainability.SOLUTION: A vertical screw press type filter device comprises: a cylindrical inside filter body 1 whose center is an axial line O extending in a vertical direction; an outside filter body 2 fixed at the outside of the inside filter body 1 with an interval so as to be a cylindrical or conical shape having the same axis as the inside filter body 1; and a ribbon screw 11 which is housed between the inside filter body 1 and the outside filter body 2 to be spirally twisting around the axial line O and which rotates around the axial line O. The inside filter body 1 is fixed by being suspended with a suspension bolt 7C inserted from an upper end side in the axial line O direction into the inner periphery of the inside filter body 1 and being supported. |
