Title
(EN) PRECISION FLOW FEEDING DEVICE
(FR) DISPOSITIF D'ALIMENTATION À FLUX DE PRÉCISION
Abstract
(EN)
A device (1) for feeding a processing device with powdery material (2) comprises a first chamber (3) having at least one fluidizing device (5) configured to fluidize and/or to potentially fluidize the powdery material (2), at least one second chamber (6) being in connection with the first chamber (3) such that fluidized and/or potentially fluidized powdery material (2) is transportable from the first chamber (3) into the second chamber (6), and at least one third chamber (9) being in connection with the second chamber (6) such, that the potentially fluidized powdery material (2) is transportable from the second chamber (6) into the third chamber (9). The device (1) is configured to defluidize the powdery material (2) such that it is present as defluidized powdery material (2) in the third chamber (9). The third chamber (9) has a discharge element (10) configured to discharge the defluidized powdery material (2).
(FR)
La présente invention concerne un dispositif (1) pour alimenter un dispositif de traitement en matériau pulvérulent (2) qui comprend une première chambre (3) dotée d'au moins un dispositif de fluidisation (5) configuré pour fluidiser et/ou pour fluidiser potentiellement le matériau pulvérulent (2), au moins une deuxième chambre (6) en liaison avec la première chambre (3) de sorte que le matériau pulvérulent fluidisé et/ou potentiellement fluidisé (2) puisse être transporté de la première chambre (3) à la deuxième chambre (6) et au moins une troisième chambre (9) en liaison avec la deuxième chambre (6) de sorte que le matériau pulvérulent potentiellement fluidisé (2) puisse être transporté de la deuxième chambre (6) à la troisième chambre (9). Le dispositif (1) est configuré pour défluidiser le matériau pulvérulent (2) de telle sorte qu'il soit présent sous la forme d'un matériau pulvérulent défluidisé (2) dans la troisième chambre (9). La troisième chambre (9) comporte un élément d'évacuation (10) configuré pour évacuer le matériau pulvérulent défluidisé (2).
