Title (EN) ISOTROPICALLY COMPRESSING PLUG SCREW FEEDER
(FR) DISPOSITIF D'ALIMENTATION À VIS SANS FIN À COMPRESSION ISOTROPE
Abstract:
(EN) A plug screw feeder for transporting and compressing granular material in a transport direction and comprising a feed screw, which comprises a screw core and has a length, which is divided into a number of length sections, each of which having a length and a start and an end as seen in the transport direction, wherein the feed screw in at least one of said length sections has a first outer diameter D1 and a first pitch hi at start of said at least one length section and a second outer diameter D2 and a second pitch h2 at end of said at least one length section, and the screw core has a first core diameter d1 at start of said at least one length section and a second core diameter d2 at end of said at least one length section, characterized in that D2/D1≅d2/d1≅h2/h1 in said at least one length section.
(FR) La présente invention concerne un dispositif d'alimentation à vis sans fin pour le transport et la compression de matériau granulaire dans une direction de transport et comprenant une vis d'alimentation, qui comprend une âme de vis et a une longueur, qui est divisée en une pluralité de sections de longueur, dont chacune a une longueur et un début et une fin lorsqu’elle est observée dans la direction de transport, la vis d'alimentation dans au moins une desdites sections de longueur ayant un premier diamètre externe D1 et un premier pas hi au début de ladite au moins une section de longueur et un deuxième diamètre externe D2 et un deuxième pas h2 à la fin de ladite au moins une section de longueur, et l’âme de vis a un premier diamètre d’âme d1 au début de ladite au moins une section de longueur et un deuxième diamètre d’âme d2 à la fin de ladite au moins une section de longueur, caractérisé en ce que D2/D1≅d2/d1≅h2/h1 dans ladite au moins une section de longueur.
