Description
Appareil mélanqeur pour produits pulvérulents.Mixer for powdery products.
La présente invention concerne les appareils mélangeurs pour produits pulvérulents. The present invention relates to mixing devices for powdery products.
On connaît de tels appareils constitués par une cuve fixe munie d'un organe d'agitation interne par exemple sous forme d'arbre rotatif à pales ou couteaux radiaux. D'autres comportent une cuve mobile, en principe rotative, munie également d'un organe d'agitation interne. Such apparatuses are known which consist of a fixed tank provided with an internal stirring member, for example in the form of a rotary shaft with blades or radial knives. Others include a mobile tank, in principle rotary, also provided with an internal agitating member.
Ces appareils supposent l'introduction dans la cuve des produits à traiter et leur sortie, après traitement, pour transvasement dans le récipient de collecte. These devices involve the introduction into the tank of the products to be treated and their exit, after treatment, for transfer to the collection container.
L'invention vise à éviter ce double transfert et elle prévoit, à cet effet, que l'appareil mélangeur est constitué par un récipient muni d'une ouverture destinée à recevoir les produits à mélanger, un support agencé pour recevoir de façon amovible ledit récipient et qui est monté sur un bâti fixe de manière à pouvoir être animé d'un mouvement cyclique, en principe un mouvement de rotation, et des moyens mélangeurs montés sur ledit support de façon à pouvoir agir à l'intérieur du réci- pient lorsque celui-ci est en place sur ce support, des moyens étant prévus pour obturer de façon étanche l'ouverture du récipient après sa mise en place sur le support. The invention aims to avoid this double transfer and it provides, for this purpose, that the mixing device is constituted by a container provided with an opening intended to receive the products to be mixed, a support arranged to receive said container in a removable manner. and which is mounted on a fixed frame so as to be able to be animated by a cyclic movement, in principle a rotary movement, and mixing means mounted on said support so as to be able to act inside the container when that -It is in place on this support, means being provided for sealingly closing the opening of the container after it is put in place on the support.
Dans une réalisation particulière, le support mobile est une cage rotative autour d'un axe horizontal, les moyens mélangeurs étant constitués par des couteaux ou organes analogues entrainés en rotation. In a particular embodiment, the mobile support is a rotary cage about a horizontal axis, the mixing means being constituted by knives or similar members driven in rotation.
A titre nullement limitatif, on a représenté au dessin annexé un exemple de réalisation de l'appareil selon l'invention, dessins sur lequel la figure unique est une vue schématique en élévation de l'appareil. By way of non-limiting example, there is shown in the accompanying drawing an embodiment of the device according to the invention, drawings in which the single figure is a schematic elevation view of the device.
Dans l'exemple représenté, l'appareil est constitué essentiellement par une cage 1 munie de deux bouts d'arbres horizontaux 2, 2' tournant dans des paliers 3, 3' portés par des supports verticaux 4, 4'. La rotation de la cage 1 est assurée par un moto-réducteur 5 dont le pignon de sortie est relié par une chaine 6 à un pignon 7 coaxial au tourillon 2 et solidaire de la cage 1. In the example shown, the apparatus consists essentially of a cage 1 provided with two ends of horizontal shafts 2, 2 'rotating in bearings 3, 3' carried by vertical supports 4, 4 '. The rotation of the cage 1 is ensured by a geared motor 5 whose output pinion is connected by a chain 6 to a pinion 7 coaxial with the pin 2 and integral with the cage 1.
A la partie supérieure de cette cage est disposé un moteur électrique 8, dont l'arbre de sortie 9 porte à son extrémité un groupe de couteaux 10. L'axe du moteur est perpendiculaire à l'axe commun des bouts d'arbres 2, 2' et le rencontre sensiblement au centre de la cage. L'alimentation du moteur 8 est assurée par les câbles Il portés par la cage 1 et les câbles d'arrivée 12 reliés aux précédents par l'intermédiaire d'un joint tournant électrique 13 monté sur l'arbre 2;
Le moteur 8, avec les couteaux 10, est porté par un plateau 14 monté coulissant sur la cage 1, par l'intermédiaire des rouleaux 15, 15'. Des vérins 16, 16' commandent le déplacement du plateau 14, grâce à un motoréducteur 17 entrainant les boites de commande 18, 18' des vis 19, 19' des vérins 16, 16'.Le moteur 17 est alimentée par l'intermédiaire des câbles 20, 21 et du joint électrique 13. Sous le plateau 14, est installé un récipient 22 destiné à recevoir les produits à mélanger et muni de pieds 23, 23'reposant sur la cage 1. Sur son orifice supérieur 24, vient s'appliquer un joint 25 dont est muni le plateau 14 lorsque celui-ci est abaissé en faisant pénétrer les couteaux dans le récipient 22. Ce plateau 14 porte également un injecteur 26 alimenté par les conduits 27, 28 et le joint tournant hydraulique 29.At the upper part of this cage is arranged an electric motor 8, the output shaft 9 of which carries at its end a group of knives 10. The axis of the motor is perpendicular to the common axis of the ends of the shafts 2, 2 'and meets it substantially in the center of the cage. The motor 8 is supplied by the cables II carried by the cage 1 and the inlet cables 12 connected to the previous ones by means of an electrical rotary joint 13 mounted on the shaft 2;
The motor 8, with the knives 10, is carried by a plate 14 slidably mounted on the cage 1, by means of the rollers 15, 15 '. Cylinders 16, 16 'control the movement of the plate 14, thanks to a geared motor 17 driving the control boxes 18, 18' of the screws 19, 19 'of the cylinders 16, 16'. The motor 17 is supplied by means of the cables 20, 21 and of the electrical seal 13. Under the plate 14, is installed a container 22 intended to receive the products to be mixed and provided with feet 23, 23'reposant on the cage 1. On its upper orifice 24, comes s' apply a seal 25 with which the plate 14 is provided when the latter is lowered by causing the knives to penetrate into the container 22. This plate 14 also carries an injector 26 supplied by the conduits 27, 28 and the hydraulic rotating joint 29.
Comme cela résulte de la description qui précède, l'appareil représenté permet d'introduire dans la cage 1, un récipient déjà rempli et d'assurer un parfait mélange des produits qu'il contient, en entraînant la cage en rotation autour de l'axe des arbres 2, 2' et en actionnant le moteur 8 pour faire tourner les couteaux 10. Lorsque les produits ont tendance à former des mottes, l'appareil joue non seulement le rôle de mixage mais également celui de brise-motte. L'introduction d'additifs par l'injecteur 26 permet encore d'améliorer le mélange. As follows from the above description, the device shown makes it possible to introduce into the cage 1, a container already filled and to ensure perfect mixing of the products it contains, by driving the cage in rotation around the axis of the shafts 2, 2 ′ and by actuating the motor 8 to rotate the knives 10. When the products tend to form lumps, the apparatus plays not only the role of mixing but also that of root-ball. The introduction of additives by the injector 26 further improves the mixture.
Dans l'exemple représenté, les couteaux 19 sont introduits dans l'orifice 24 du récipient 22 et le joint 25 appliqué sur cet orifice par abaissement du plateau 14 commandé par les vérins 19, 19'. In the example shown, the knives 19 are introduced into the orifice 24 of the container 22 and the seal 25 applied to this orifice by lowering the plate 14 controlled by the jacks 19, 19 '.
Dans une variante, non représentée, le plateau, porteur des couteaux et de leur moteur, ainsi que du joint, est fixe et le récipient repose sur un plateau sous lequel est -prévu un matelas pneumatique. Par gonflage de ce matelas le récipient est rapproché des couteaux qui pénétrent par son orifice, et celui-ci s'applique contre le joint. In a variant, not shown, the plate, carrying the knives and their motor, as well as the seal, is fixed and the container rests on a plate under which an air mattress is provided. By inflating this mattress the container is brought closer to the knives which penetrate through its orifice, and the latter is applied against the joint.
