Screws filter press for the filtration and / or concentration of a fluid, solids-laden discharge flow of suspension and method for the filtration and / or concentrating

摘要

A screws filter press (10) for filtering and / or concentration of a fluid, solids-laden discharge flow of suspension (s) with a motor (m), which drives a motor shaft (50) which, via a clutch (51) which drives a drive shaft (52), which is rotatably mounted on the motor (m) to form a seal housing (40), with a head region (k) and a foot region (f), is attached, within the housing (40) a rotation of screw (20) is provided, containing a roller (21) and at least one laterally connected stripping body (23), a filter element (22), is present, the rotation of screw (20) and the filter element (22) form a core (25), to the filter element (22) on its outside, a separation chamber (24), to the housing (40) in the foot region (f) an inlet (33) for the suspension (s) is connected, a permeate stream outlet (31) is connected, at the housing (40) in the region of the head (k) a retentate stream outlet (32) is connected, characterized in that the roller (21) on the outside / the inner side of the filter element (22) along its longitudinal axis / axis of symmetry in the direction of the head region (k), at least in some regions, in particular conically, is shaped to expand, i.e, a rising outer diameter / inside diameter, the drive shaft (52) and the rotation of screw (20), along a to the axis of rotation (w) coaxial direction of displacement (v), there are to be longitudinally displaceable.n="29"
