摘要： Described is a screw filter press comprising a screw shaft, which has at least one coil turn and two screw shaft ends, the shaft axis of which is oriented parallel to the gravity vector and which is supported on one side via the upper screw shaft end thereof and which is connected to a rotary drive, and which is enclosed coaxially, at least in its lower partial area in a so-called filter area by a cylindrical filter tube, which is provided with openings and at which a filtrate space adjoins radially, to which underpressure can be applied. The invention is characterized in that a sliding tube, which radially surrounds the screw shaft in the direction of the upper screw shaft end in a fluid-tight manner, follows coaxially to the filter tube at the same inner diameter as the filter tube, that provision is made between the at least one coil turn of the screw shaft and the sliding tube for a radial play and that the at last one coil turn of the screw shaft adjoins the filter tube in the area of the filter tube either indirectly or directly at the inner wall.
