<p>This vertical screw press-type filtration device comprises: an inner filtration body (1) which has a circular cylindrical or circular conical shape centered on a vertically extending axis (O) and which is affixed; an outer filtration body (2) which has a circular cylindrical or circular conical shape coaxial with the inner filtration body (1) and which is affixed on the outside of the inner filtration body (1) at a distance therefrom; and a ribbon screw (11) which has a shape helically twisted about the axis (O), is housed between the inner filtration body (1) and the outer filtration body (2), and is rotated about the axis (O). The inner filtration body (1) and the outer filtration body (2) are affixed while being supported and suspended from the upper end side in the direction of the axis (O), and therefore, the height of a space for filtration, which is formed between the inner filtration body (1) and the outer filtration body (2), does not increase. Consequently, the efficiency of work for assembling and maintenance increases and a conveyor, etc. for transporting and collecting a substance filtered out of a material to be treated can be arranged at a relatively low position.</p> |
