Title (EN) METHOD AND DEVICE FOR KEEPING CONSTANT THE FLOW RATE OF BULK MATERIAL
(FR) PROCEDE ET DISPOSITIF POUR MAINTENIR CONSTANT LE DEBIT D"UN MATERIAU EN VRAC
Abstract: front page image
(EN)A method for keeping constant the flow rate of a bulk material consists in subjecting the bulk material to the influence of an electric field of high voltage to generate on its particles surface-bound charges and passing the thus charged bulk material through an electromagnetic field of continuously registered intensity and, depending on the change of the field intensity, in determining the degree of variation of the flow rate of the bulk material from its preset value. A device for controlling the low rate comprises an inductance coil (1) oriented coaxially around a diamagnetic pipe (2) from which the bulk material flows. The primary winding (4) of the coil is connected to a direct current source whereas the secondary winding (5) of the coil is connected to an indicator (6). The device comprises as well two electrodes intended for generating surface-bound charges on the particles of the bulk material, one (7) of the electrodes being mounted inside a bunker, on the way of the low of the bulk material and both electrodes being connected to a high voltage source (8).
(FR)Un procede pour maintenir constant le debit d"un materiau en vrac consiste a soumettre le materiau en vrac a l"influence d"un champ electrique a haute tension pour produire sur ses particules des charges de surface et a faire passer le materiau en vrac ainsi charge au travers d"un champ electromagnetique dont l"intensite est enregistree en permanence et, en fonction du changement de l"intensite du champ on determine le degre de fluctuation du debit du materiau en vrac a partir de sa valeur predeterminee. Un dispositif de commande du debit comprend une bobine a inductance (1) orientee coaxialement autour d"un tube diamagnetique (2) d"ou s"ecoule le materiau en vrac. L"enroulement primaire (4) de la bobine est connecte a une source de courant continu tandis que l"enroulement secondaire (5) de la bobine est connecte a un indicateur (6). Le dispositif comprend egalement deux electrodes prevues pour produire des charges de surface sur les particules du materiau en vrac, l"une d"elles (7) etant montee a l"interieur d"un caisson, sur le chemin d"ecoulement du materiau en vrac et les deux electrodes etant connectees a une source de haute tension (8).
