An apparatus is described for separating the liquid portion from the solid portion of a liquid, finely disperse system, for example ceramic slip, having a worm (12) provided in a cylindrical housing (14), driven and surrounded by a filter aid (13), means for supplying slip at one end of the housing
An apparatus is described for separating the liquid portion from the solid portion of a liquid, finely disperse system, for example ceramic slip, having a worm (12) provided in a cylindrical housing (14), driven and surrounded by a filter aid (13), means for supplying slip at one end of the housing and a narrow solid discharge located on the worm axis at the other end of the housing, in which apparatus the filter aid (13) is inserted (at 21) so as to be secured against rotation in a massive casing forming the cylindrical housing (14), this casing being provided on its surface facing the filter aid (13) with a plurality of spaced peripheral grooves (15) which open out into a filtrate outflow (5), and the surface of the filter aid (13) facing the worm (12) being covered with an abrasion-proof, sufficiently wide-meshed screen (17), thereby creating a worm channel with a flat design, in which the slip is circulated so strongly by the relative movement between the worm and the worm cylinder that the liquid concentration is approximately constant across the cross-section of the worm channel and the liquid slip cannot filter through at the worm core up to the discharge mouthpiece of the press.

An apparatus for separating the liquid portion from the solid portion of a liquid, finely dispersed material, in particular a ceramic slip, said apparatus having an internal pressure resistant cylindrical housing, a driven worm mounted therein, means for supplying the slip at one end of the housing
An apparatus for separating the liquid portion from the solid portion of a liquid, finely dispersed material, in particular a ceramic slip, said apparatus having an internal pressure resistant cylindrical housing, a driven worm mounted therein, means for supplying the slip at one end of the housing and a narrow solid discharge throat at the other end of the housing, said apparatus characterized in that a filter means is mounted within said housing and surrounds the worm, said housing supporting said filter means against radial pressure and anchor means securing said filter means to said cylindrical housing against rotation, said filter means having slip trapping means on its inner face for capturing and holding stationary a thin layer of the slip between it and the adjacent face of said worm thereby forming a smooth surface of reduced abrasive effect surrounding said worm, against which the worm can move the slip both axially and radially of the worm chamber with reduced resistance to axial movement, said layer being thin enough to permit liquid filtrate to pass through it, said filter means including a plurality of cylindrical sections, a ring element seated between each pair of adjacent sections and concentric therewith, said slip trapping means including plates secured to said ring elements and protruding radially inwardly beyond the inner faces of said cylindrical sections and axially over portions of the inner faces of said cylindrical sections for trapping the layer of slip, a plurality of axially spaced grooves communicating with said filter member for receiving filtrate separated from the slip, a filtrate discharge port, said grooves communicating with said port.
