Description

La présente invention est relative à une vis mélangeuse articulée ainsi qu'à un dispositif de mélange comportant une cuve dans laquelle est disposée au moins une telle vis mélangeuse. Les dispositifs connus pour mélanger des éléments solides ou pâteux comprennent tous une cuve dans laquelle est situé un moyen de mélange tels que des agitateurs en forme de cadre, des vis mélangeuses d'axe vertical ou d'axe oblique. Par exemple, dans le document FR-2666247-A est décrite une mélangeuse qui comprend un caisson cylindrique et une vis comprenant une paroi d'entraînement hélicoïdale fixée à un arbre monté pour tourner coaxialement à la paroi cylindrique. Le diamètre intérieur du caisson cylindrique et celui de l'enveloppe du mouvement décrit par la vis sont tels que l'espace ménagé entre eux est suffisamment faible pour que des éléments du mélange ne se collent par la paroi cylindrique. Ce mode de réalisation interdit donc des cuves de mélange de grand diamètre. D'après le document FR-2354806-A il est connu un mélangeur pour des matières pulvérulentes qui comprend une trémie évasée vers le haut, dans laquelle une vis peut décrire un mouvement orbital ou cycloïdal : cette vis peut ainsi racler la paroi interne de la trémie mais le centre de la trémie peut ne pas être mélangé. Aussi un des buts de présente invention est-il de fournir une vis mélangeuse qui permet de mélanger des produits solides situés non seulement dans la partie centrale d'un dispositif de mélange, mais également à proximité de la paroi interne de celui-ci quelle qu'en soit ta forme. Un autre but de l'invention est de fournir un dispositif pour mélanger des matières solides du genre comprenant une cuve dans laquelle est situé une vis mélangeuse Ces buts, ainsi que d'autres qui apparaîtront par suite, sont atteints par une vis mélangeuse constituée par un arbre sur lequel est disposée une paroi d'entraînement hélicoïdale, laquelle vis est caractérisée, selon la présente invention, par le fait que l'arbre comporte une première partie tournant autour de son axe, dont une extrémité est reliée à un dispositif d'entraînement, et une seconde partie articulée sur l'autre extrémité de la première partie. Avantageusement, la seconde partie représente environ au moins la moitié de la longueur totale de l'arbre. De préférence, la seconde partie est articulée sur la première partie de l'arbre par une liaison de type rotule. The present invention relates to an articulated mixing screw and a mixing device comprising a tank in which is disposed at least one such mixing screw. Known devices for mixing solid or pasty elements all comprise a tank in which is located a mixing means such as frame-shaped stirrers, mixing screws of vertical axis or oblique axis. For example, in FR-2666247-A is described a mixer which comprises a cylindrical well and a screw comprising a helical drive wall attached to a shaft mounted to rotate coaxially with the cylindrical wall. The inside diameter of the cylindrical box and that of the envelope of the movement described by the screw are such that the space between them is sufficiently small so that elements of the mixture do not stick to the cylindrical wall. This embodiment therefore prohibits mixing tanks of large diameter. According to the document FR-2354806-A, it is known a mixer for pulverulent materials which comprises an upwardly flared hopper, in which a screw can describe an orbital or cycloidal movement: this screw can thus scrape the inner wall of the hopper but the center of the hopper may not be mixed. Therefore, it is an object of the present invention to provide a mixing screw which allows the mixing of solid products located not only in the central part of a mixing device, but also in the vicinity of the inner wall thereof. 'in your form. Another object of the invention is to provide a device for mixing solids of the type comprising a tank in which a mixing screw is located. These and other objects which will appear as a result are achieved by a mixing screw constituted by a shaft on which is arranged a helical drive wall, which screw is characterized, according to the present invention, in that the shaft has a first portion rotating about its axis, one end of which is connected to a device of drive, and a second part articulated on the other end of the first part. Advantageously, the second part represents at least half of the total length of the tree. Preferably, the second part is articulated on the first part of the shaft by a ball-type connection.

La présente invention concerne également un dispositif de mélange ou cuve comportant au moins une telle vis de mélange. La description qui va suivre, et qui ne présente aucun caractère limitatif, doit être lue en regard des figures annexées, parmi lesquelles : - la figure 1 représente une vue de face d'une vis mélangeuse articulée selon la présente invention, l'arbre de celle-ci étant droit ; - la figure 2 représente en vue de face la vis selon la figure 1dont une partie est inclinée ; et, - la figure 3 représente une vue en perspective, avec arrachement partiel, d'un dispositif de mélange comportant une telle vis. Ainsi qu'on peut le voir sur les figures, une vis mélangeuse, désignée dans son ensemble par la référence 1, comporte un arbre 2 sur lequel est disposée une paroi d'entraînement hélicoïdale 3. Selon la présente invention, cet arbre 2 comprend une première partie 2a tournant autour de son axe et dont une extrémité est reliée à un dispositif d'entraînement, et une seconde partie 2b articulée par une liaison de type rotule sur l'autre extrémité de la première partie 2a : cette seconde partie peut donc en rotation décrire un cône. L'inclinaison de cette seconde partie 2b par rapport à la première partie 2a peut être réglée par tout système : manuel, lame de ressort, vérin hydraulique avec boule d'azote ou tout autre moyen permettant ainsi une inclinaison fixe ou pouvant varier durant le fonctionnement en fonction de la nature des produits à mélanger. L'angle d'inclinaison de la seconde partie 2b par rapport à la première partie 2a est de préférence compris entre 0 et 25 degrés. La présente invention est aussi relative à un dispositif de mélange ou cuve 3 comportant une telle vis de mélange 1. Mais, cette cuve peut comporter deux ou plusieurs de telle vis de mélange comme selon le présent exemple de réalisation représenté à la figure 3. Dans cet exemple, les vis de mélange 1 et 10 sont disposées verticalement dans cette cuve 3 : leurs arbres, 2 et 20 respectivement, comportent une première partie dont une extrémité est en relation, de façon connue, avec un dispositif d'entraînement. La seconde partie de ces arbres 2 et 20 est inclinable de façon que son mouvement de rotation autour de la verticale épouse autant que possible la forme de l'intérieur de la paroi 4 de la cuve 3. The present invention also relates to a mixing device or tank comprising at least one such mixing screw. The description which follows, and which has no limiting character, should be read with reference to the appended figures, among which: FIG. 1 represents a front view of an articulated mixing screw according to the present invention, the this being right; FIG. 2 is a front view of the screw according to FIG. 1, a part of which is inclined; and - Figure 3 shows a perspective view, partially broken away, of a mixing device comprising such a screw. As can be seen in the figures, a mixing screw, designated as a whole by the reference 1, comprises a shaft 2 on which is disposed a helical drive wall 3. According to the present invention, this shaft 2 comprises a first part 2a rotating about its axis and one end of which is connected to a drive device, and a second part 2b articulated by a ball-type connection on the other end of the first part 2a: this second part can therefore rotation describe a cone. The inclination of this second part 2b relative to the first part 2a can be adjusted by any system: manual, leaf spring, hydraulic cylinder with nitrogen ball or any other means thus allowing a fixed inclination or may vary during operation depending on the nature of the products to be mixed. The angle of inclination of the second portion 2b with respect to the first portion 2a is preferably between 0 and 25 degrees. The present invention also relates to a mixing device or tank 3 comprising such a mixing screw 1. However, this tank may comprise two or more such mixing screws as in the present embodiment shown in FIG. In this example, the mixing screws 1 and 10 are arranged vertically in this tank 3: their shafts, 2 and 20, respectively, comprise a first part, one end of which is in relation, in known manner, with a driving device. The second part of these shafts 2 and 20 is tilting so that its rotational movement around the vertical wife as much as possible the shape of the inside of the wall 4 of the tank 3.

Une telle cuve peut ainsi servir pour mélanger notamment des produits agricoles tels que maïs, herbe, foin, paille soit entre eux soit avec des compléments alimentaires par exemple. Such a tank can thus be used to mix such agricultural products such as corn, grass, hay, straw or between them or with food supplements for example.
