Title (EN) SYSTEM FOR SEPARATION OF MATERIALS USING SUCTION AIR POWER
(FR) SYSTEME SERVANT A LA SEPARATION DE MATERIAUX PAR ASPIRATION D'AIR
Abstract:
(EN) A mixture of material is transported by a vibrating conveyor (B), deposited thereon by belt conveyor (A), before an inlet (11) of a suction mouth (1). Suction mouth (1) is adjustable in all directions and by using the adjustable units (2) mounted on the suction duct (4), the height of the mouth (1) may be adjusted above the transported mixture of materials which is to be treated. The width of the opening (11) of suction mouth (1) is adjustable (20-26) to shape the mouth either symmetrically or asymmetrically. The suction power at the inlet (11) of the suction mouth (1) is regulated by adjusting its width combined with outside air supply using an air inlet valve (3) associated with suction duct (4) and adjustments of the capacity of exhaust fan (8). The exhausted air is fed to a cyclone (5) in which the materials which are sucked up and transported with the air have to be deposited. The behaviour and velocity of flow of the air entering cyclone (5) are adjustable by using the air inlet valve (3) and adjustment of fan capacity. The suction of fan (8) is connected at the outlet pipe (7) of the cyclone (5). The air exhausted via fan (8) is blown through a dust filter (9) and collected particles are transported by conveyor (10) into a bag (C).
(FR) Un convoyeur à bande (A) dépose un mélange de matériaux sur un convoyeur vibrant (B) qui achemine ces matériaux jusqu'à une entrée (11) d'une bouche d'aspiration (1). La bouche d'aspiration (1) est adaptable dans toutes les directions et, en utilisant les unités d'adaptation (2) montées sur la tuyauterie d'aspiration (4), la hauteur de la bouche (1) peut être adaptée de façon qu'elle se trouve au-dessus du mélange de matériaux acheminés pour être traités. La largeur de l'ouverture (11) de la bouche d'aspiration (1) est adaptable (20-26) de façon que la forme de la bouche soit symétrique ou asymétrique. On règle la puissance d'aspiration à l'entrée (11) de la bouche (1) en adaptant la largeur de cette dernière, ainsi qu'une alimentation en air venant de l'extérieur à l'aide d'une vanne d'entrée (3) en liaison avec la tuyauterie d'aspiration (4), et en adaptant la capacité du ventilateur aspirant (8). L'air évacué est acheminé jusqu'à un cyclone (5), dans lequel les matériaux aspirés et transportés par l'air doivent être déposés. Le comportement et la vitesse du flux d'air qui entre dans le cyclone (5) sont adaptables grâce à une vanne d'entrée d'air (3) et au réglage de la capacité du ventilateur aspirant. La conduite d'aspiration du ventilateur (8) est connectée à un tuyau de sortie (7) du cyclone (5). L'air évacué par le ventilateur (8) est soufflé à travers un filtre de poussières (9) et les particules recueillies sont transportées par un conveyeur (10) dans un sac (C).
