The invention relates to a screw press (2) that can be used as a dewatering device for compressing and dewatering a suspension of a fermentation plant or biogas plant. The screw press (2) comprises a press chamber (20), in which a screw shaft (202) is supported in such a way that the screw shaft is surrounded by a screen jacket (203) and can be rotated about a screw shaft axis (L), wherein the screen jacket (203) is fastened to a screen-jacket retaining device (204) within the press chamber (20) and the screen jacket (203) is formed by a plurality of multi-part screen cages (2030) having screen-cage inserts (2033). The multi-part screen cages (2030) are formed by two screen-cage half-shells (2031) and (2032), between which at least one pivoting hinge (2043) is arranged, which is arranged on a bar (2040), which extends through the press chamber (20) and is arranged parallel to the pivot axis (L), as part of the screen-jacket retaining device (204) and is firmly connected to both screen-cage half shells (2031, 2032). The screen-cage half-shells (2031) and (2032) are supported in such a way that the screen-cage half-shells can be pivoted in relation to each other, such that unhindered access to the screen-cage inserts (2033) is enabled in the swung-open state. In addition, a cage tab (S) is arranged on each of the screen-cage half-shells (2031, 2032) on the side facing away from the pivoting hinge (2043), which cage tab is detachably fastened to the screen-jacket retaining device (204) by means of cage closing means (2044) in the closed state of the screen-cage half-shells (2031, 2032). |
