Abstract

Dispositif permettant en continu de former des portions de matière en poudre ou en grain et d'introduire celles-ci dans un conduit de transport pneumatique où elles sont transportées sous forme de portions alternant avec des coussins d'air, le dispositif comprenant un poste d'expédition raccordé à un conduit d'air comprimé et des organes de commande pour alimenter le poste d'expédition par intermittence en air comprimé. Un sas rotatif 2 étanche à l'air introduit la matière dans le poste d'expédition 1 et à la sortie 1b du poste d'expédition 1 ou, en aval de celui-ci, au conduit de transport 4 est raccordé un conduit d'air comprimé additionnel 17 équipé d'organes de commande 18, 24 pour l'amenée intermittente d'air comprimé dans le conduit de transport 4. L'invention est applicable, par exemple, au transport de matières synthétiques en granulé.Device for continuously forming portions of powder or grain material and introducing the latter into a pneumatic transport duct where they are transported in the form of portions alternating with air cushions, the device comprising a station for 'dispatch connected to a compressed air duct and control units to supply the dispatch station intermittently with compressed air. An airtight rotary airlock 2 introduces the material into the shipping station 1 and at the outlet 1b of the shipping station 1 or, downstream thereof, to the transport duct 4 is connected a duct of additional compressed air 17 equipped with control members 18, 24 for the intermittent supply of compressed air into the transport duct 4. The invention is applicable, for example, to the transport of synthetic materials in granules.
