| Described is filter matting (20) for reversible-flow filter, the matting having layers with decreasing mesh size disposed on a rigid base (21). The matting layers are joined to each other and to the base preferably by means of sintered joints and hence braced with respect to each other. Particularly preferred is the use of such filter matting in the operation of a pressure filter which can be fitted with equipment for automatically removing the filter cake. Because of the rigid nature of the filter matting, a reverse flow can be established using a liquid or gaseous flushing agent to detach the filter cake rapidly and completely, without the filter matting being distorted or torn open. Any residual layer of filter cake is removed by using a swirling flow. The use of heated gaseous flushing agent enables the filter cake residues to be dried more rapidly. | ||||||

| PURPOSE: To regulate a grain sieving effect at a velocity of an ascending stream by passing the sand stream of sand mixed with dust on the horizontal or slightly inclined surface of a sieving bed for particles heavier than sand particles and using the ascending stream as a carrier stream for the dust components. CONSTITUTION: An air permeable intermediate plate or temporary bottom 16 having a transverse direction grid 17 and a longitudinal direction grid is fixed spatially from a bottom plate 12 to a housing wall body in a housing 10 and the sieving bed 18 for pellets or balls of copper or steel is placed on the intermediate plate 16. Air is introduced in an arrow X direction by an air feed conduit 40 having a throttling member 38 into the bottom space 20 of the housing and is blown through the sieving bed 18. The intermediate plate 16 is connected to a knocking mechanism. The air flows through a sand-dust bed 36 and entrains the dust toward the air groove holes 24 of a guide pipe 26. The dust is transported by the air (arrow Z) of the guide pipe 26. The mixture composed of the sand and dust introduced by a sand introducing means 30 is separated on the sieving bed 18 and the sand is discharged from a sand discharge port 34.

A fluidized-bed classifier has a vessel (20) defining a space divided into an upper fluidized-bed chamber (22) and a lower gas chamber (23) by a perforated dispersion plate (21) having the shape of a funnel. Rising currents of a gas, such as air, are blown through the dispersion plate (21) into the upper fluidized-bed chamber to produce a fluidized bed of a particulate material over the dispersion plate. The lower gas chamber (23) is divided into a first gas chamber (23a) and a second gas chamber (23b) by a partition plate (29). The gas is supplied into the first air chamber (23b) so that rising gas currents of a velocity necessary for fluidizing coarse particles contained in the particulate material red into the vessel are blown from the first air chamber (23a) through the dispersion plate (21) into the fluidized-bed chamber. The gas is supplied into the second air chamber(23b) so that rising gas currents of a velocity lower than the velocity of the rising gas currents blown from the first air chamber (23a) into the fluidized-bed chamber (22) are blown into the fluidized-bed chamber so that coarse particles contained in the particulate material are not fluidized and does not flow together with fine particles into a fine particle discharge chute (28). |

Bei einem Verfahren zum Sichten von Sand od.dgl. Rieselgut -- insbesondere zum Entstauben von Staub enthaltendem Gießereisand -- unter Einsatz eines Luftstromes wird der mit Staub gemischte Sand als Strom über die etwa horizontal oder leicht geneigte Oberfläche einer Schüttung aus gegenüber dem Strom schwereren Teilchen geführt und diese Schüttung von aufsteigender Luft als Transportströmung für die Staubanteile durchströmt. Eine für dieses Verfahren geeignete Vorrichtung weist in einem Gehäuse (10) auf einem siebartigen Zwischenboden (16) eine Schüttung (18) mit etwa horizontaler oder etwas geneigter Oberfläche (19) auf, die von einem Luftstrom (x) durchsetzt ist, wobei die Teilchen der Schüttung aus gegenüber dem Sandbett (36) schwererem Material sind. |

Im Betrieb werden die Konzentratorebene (3) und die Steinabsaugebene (4) in Schwingung versetzt. Luft wird bei (19) abgesaugt. Die durch die Konzentratorebene (3) durchströmende Luft fluidisiert das durch den Zulauf (13) eingelassene Korngut, so dass es gleichmässig in Neigungsrichtung abfliesst. Spezifisch schwere Bestandteile ordnen sich an der Unterseite, spezifisch leichte Bestandteile ordnen sich an der Oberseite des Stromes. Im Durchfallbereich (7) fallen die spezifisch schweren Bestandteile nach unten. Spezifisch leichte Bestandteile wandern zum Leichtfraktionsauslass (14). Beim Fall nach unten werden die spezifisch schweren Bestandteile durch die Luftströmung in den Abteilen (10) abgebremst, können aber wegen der Querstege (11) nicht in Neigungsrichtung abfliessen. Sie werden daher in den Abteilen verwirbelt, bevor sie durch die Oeffnungen der zweiten Strömungsmaske (9) fallen. Durch diese Verwirbelung wird für eine gleichmässige turbulente Luftströmung durch die erste Strömungsmaske (8) gesorgt. Dadurch wird eine Störung der Schichtung des Korngutstroms vermieden. Da ferner eine gleichmässige Beschickung der Steinausleseebene (4) erreicht wird, wird der Steinauslesevorgang verbessert. |

| An apparatus (10) for providing a fluidized bed (24) to effect the separation of a mixture of articles (58, 60) having at least a first density and a second density that is greater than the first density into separate groups. The apparatus (10) includes an inclined trough (12) which is supplied at an input end (18) with either a fluidization medium, such as sand, or a mixture of articles (58, 60) from which a fluidized bed (24) is formed by forcing gas upwardly through the bottom of the trough and through the fluidization medium or the mixture. In the case where a fluidization medium such as sand is used, the mixture of articles is introduced into the fluidized bed medium so as to be entrained therewith to effect separation as the articles travel in the direction of flow of the fluidized bed medium. Vertical oscillatory movement is imparted to the inclined trough (12) to improve the separation and layering where the mixture of articles is fluidized, or to improve the density uniformity where a fluidization medium such as sand is fluidized as the bed. | ||||||
