Abstract
(EN)
A cyclone type receiver (180) can be used in a pneumatic conveyor system for accurately delivering a wide variety of particulate materials. A receiver may include a cylindrical body configured to hold a filter (151). The top end of the cylindrical body may include an air inlet (181) for receiving a ducted air stream filled with a particulate material, and may be configured to convey the ducted air stream helically toward a conical section attached to the cylindrical section. The conical section may be configured to route the ducted air in a helical manner to remove the particulate material from the ducted air. In such a configuration, the filter (151) and the conical section may remove particulate material, thereby preferably increasing the transfer accuracy of the system and reducing the footprint of a traditional pneumatic conveyor system.

Un récepteur du type à cyclone peut être utilisé dans un système de transporteur pneumatique pour distribuer avec précision un grande choix de matériaux particulaires. Un récepteur peut comprendre un corps cylindrique conçu pour contenir un filtre. L'extrémité supérieure du corps cylindrique peut comprendre une entrée d'air permettant de recevoir un flux d'air canalisé chargé d'un matériau particulaire et peut être conçue pour transporter le flux d'air canalisé de manière hélicoïdale vers une section conique fixée à la section cylindrique. La section conique peut être conçue pour acheminer l'air canalisé d'une manière hélicoïdale pour retirer le matériau particulaire de l'air canalisé. Dans une telle configuration, le filtre et la section conique peuvent retirer un matériau particulaire, ce qui permet d'augmenter de préférence la précision de transfert du système et de réduire l'empreinte d'un système de transporteur pneumatique classique.
