Abstract: A device for concentrating an object to be treated has a filter body in which a movable plate is disposed between adjacent annular fixed plates, the moveable plate being formed in the same annular shape. Sludge filtrate passes through filtrate inflow gaps between the fixed plates and the movable plate before being caused to flow into the filter body. The movable plate is moved so that solids in the sludge are kept from clogging the filtrate inflow gaps. A cleaning member is caused to rub against the outer peripheral surfaces of the fixed plates so that solids adhering to the outer peripheral surfaces of the fixed plates are scraped off. The movable plates of said device are caused to perform a circular movement by eccentric cams fixed to the shaft. The cleaning member is fixed to the shaft, and caused to rotate around the shaft by the rotation of the shaft so that solids adhering to the outer peripheral surfaces of the fixed plates are scraped off.

Abstract: A solid-liquid separation device includes a plurality of fixed members and movable members that are movably disposed between the adjacent fixed members, and a screw extending through the fixed members and the movable members in a state where the screw is not in contact with the fixed members and the movable members. The screw is rotationally driven about a center axis line thereof. A filtrate separated from an object is discharged to the outside of the solid-liquid separation portion through filtrate discharge gaps, and the object that has a reduced liquid content ratio is discharged from the outlet to the outside. In order to increase significantly a dewatering ratio, the movable members are formed to move while penetrating closer to the center axis line of the screw than an outer circumferential edge of the blade of the screw, without coming into contact with the screw.

Abstract: A press-formed product includes a top panel portion and a side panel portion connected to the top panel portion through a bent portion that is curved so as to have an arc shape. The top panel portion includes a recessed portion that is curved so as to have an arc shape in a direction opposite to a direction in which the bent portion is curved.
