| Le séparateur (10) est approprié au traitement de produits agricoles dans un lit fluidisé (94) s'écoulant au travers d'une auge inclinée (88) sous l'influence de la gravité. Le milieu de fluidisation (96) recircule depuis l'extrémité de sortie de l'auge (88) pour revenir à l'extrémité d'entrée de l'auge en utilisant un tambour de recirculation (64) disposé horizontalement et encerclant latéralement l'extrémité de sortie de l'auge (88) et supporté en rotation autour de son propre axe longitudinal. La surface interne du tambour (64) comprend une série sans fin de poches de réception (200) qui récupèrent le sable sous l'extrémité de sortie de l'auge (88) et le soulèvent au-dessus. Un amortisseur (174) monté à l'extrémité de sortie de l'auge (88) est utilisé pour accélérer l'établissement du lit fluidisé (94) en obstruant temporairement l'écoulement du lit fluidisé (94). Un détecteur à ultrasons (188) est utilisé pour déterminer la profondeur de l'auge (88) et, d'après cette profondeur, commander le débit du milieu de fluidisation (96). Le prétraitement de l'air passant de force au travers du milieu de fluidisation (96) pour créer le lit fluidisé (94) s'effectue par une cheminée d'admission d'air (48) qui s'étend sur une certaine distance au-dessus du séparateur (10), un filtre d'air pour éliminer de l'air ambiant les particules dont la grosseur dépasse une valeur prédéterminée, et un dispositif de chauffage d'air (144) qui fait monter la température de l'air de manière adéquate pour éliminer l'humidité du lit fluidisé (94). | ||||||

A fluidized-bed drying and classifying apparatus is provided with a main body (10) in which a fluidized bed is formed to dry a granular material and to classify the same into fine particles and coarse particles. A perforated gas-distributing plate (12) is disposed in a lower part of a region in which a fluidized bed (14) is formed in the main body (10), a wind box having the shape of a hopper is disposed below the perforated gas-distributing plate. A dropped material discharge device (29) is connected to the lower end of the hopper-shaped wind box (16) to discharge the material dropped into the wind box (16). A gas supply system (110) is connected to the wind box (16) to supply a fluidizing gas that serves as a drying hot gas and a classifying gas into the wind box. A material supply opening portion (20) is mounted to the main body (10) to feed the granular material. A discharge chute (24) is connected to the main body (10) to discharge dried coarse particles. A gas discharge opening portion (56) is connected to the main body (10) to discharge an exhaust gas containing fine particles. The gas supply system (110) includes a flow controller (111) to control classification particle size by controlling the flow rate of the gas supplied into the wind box (16), and a temperature controller (112) to control drying degree through the adjustment of temperature of the hot gas supplied into the wind box (16) according to the adjusted flow rate. |

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). |

| An air distribution plate (11) for incorporation into a material conveyor or a material separator has a plurality of apertured zones alternately arranged along the length of the plate. The apertures in the first series of zones (18) are inclined in the direction of the desired flow of material in the case of the conveyor and in the direction of the desired air flow in the case of the separator and the apertures in the second series of zones (19) incline in the opposite direction by the same amount. Each zone (19) in the second series has fewer apertures than the zone (18) of the first series. | ||||||

| A separator (10) suitable for processing agriculture products in a fluidized bed (94) flowing through an inclined trough (88) under the influence of gravity. The fluidization medium (96) is recirculated from the output end of the trough (88) back to the input end thereof using a recirculation drum (64) horizontally disposed laterally encircling the output end of the trough (88) and supported for rotation about its own longitudinal axis. The inner surface of the drum (64) includes an endless series of receiving pockets (200) for collecting sand below the output end of the trough (88) and lifting it thereabove. A damper (174) at the output end of the trough (88) is used to accelerate the establishment of the fluidized bed (94) therein by temporarily obstructing the flow of fluidized bed (94). An ultrasonic sensor (188) is used to determine the depth of the trough (88) and based thereon to control the rate at which fluidization medium (96) is provided thereto. Pretreatment of the air forced through the fluidization medium (96) to create the fluidized bed (94) occurs through the use of an air intake stack (48) extending a substantial distance above the separator (10), an air filter for removing from ambient air particles exceeding a predetermined size, and an air heater (144) for raising the temperature of the air adequately to permit it to remove moisture from the fluidized bed (94). | ||||||

| 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. | ||||||

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. |
