  Perfectionnements apportés aux tambours mélangeurs à marche continue. 



   L'invention concerne un tambour mélangeur à marche continue, dans lequel la matière à mélanger est amenée à su- Dir, en outre, de son cheminement progressif suivant l'axe du tambour au cours du roulement, un mouvement de va.-et-vient, donc alternatif dans   la.   direction de cet axe, par suite de quoi on réalise une action de mélange parfaite. 



   Le nouveau tambour conforme à l'invention est ca-   ractérisé   par le fait que, d'une part, il est comme d'ordi- naire mobile autour de son axe géométrique et muni à ses 

 <Desc/Clms Page number 2> 

 extrémités respectives d'une ouverture de chargement et d'une ouverture de décharge, et que, d'autre part, il est divisé en un certain nombre de chambres successives par une ou plusieurs cloisons séparatrices disposées obliquement par rapport à l'axe longitudinal, lesquelles chambres communiquent entre el- les à l'aide d'ouvertures ménagées dans les parties desdites cloisons les plus voisines de l'ouverture de chargement du tambour. 



   En constituant la paroi du tambour sous la forme d'un tamis, au moins du côté de son ouverture de sortie, le dispositif mélangeur peut en même temps être utilisé pour le tamisage. 



   Le dessin montre, à titre d'exemple, deux modes de réalisation du nouveau dispositif mélangeur, dans des vues schématiques. 



   La figure 1 est une coupe axiale d'une machine à mé- langer et tamiser équipée avec le tambour conforme à l'inven- tion. 



   La figure 2 est une coupe transversale par la ligne 2-2 de la figure 1. 



   Les figures 3 et   4   sont respectivement des coupes axiale et transversale de la même machine établie suivant le second mode de réalisation. 



   Le tambour 1 est monté de façon pivotante autour de son axe longitudinal et horizontal, à l'aide par exemple de rouleaux porteurs 13, et il peut être entraîné en rotation par tout dispositif approprié. A une extrémité est ménagée l'ouverture de chargement 14 dans laquelle débouche le conduit 3 du dispositif de   chargement   7, lequel est muni de trémies 6, 6a pour les différentes matières à mélanger. A l'autre extré- mité le tambour possède une ouverture de décharge 9. 

 <Desc/Clms Page number 3> 

 



   Conformément à l'invention, ledit tambour est parta- gé en plusieurs chambres 15 par des cloisons transversales 2 disposées obliquement par rapport à son axe longitudinal. La perfection du mélange croît avec le nombre des cloisons ou desdites chambres. A la partie desdites cloisons la plus rap- prochée de l'ouverture de chargement 14 sont prévus des pas- sages 4 mettant en communication les chambres 15 les unes avec les autres, passages dant la hauteur radiale décroît progressivement depuis leur extrémité située en avant dans le sens de rotation jusqu'à leur extrémité située en arrière. 



   Avantageusement, le tambour est muni, principale- ment vers l'ouverture de sortie 9, d'un ou de plusieurs an-   nea,ux   de retenue 5, qui font saillie sur la paroi dudit tam- bour. Dans le mode de réalisation de la figure 1, la portion avant Ia du tambour est pleine, tandis que la portion Ib, Ic. est réalisée sous forme   d'un   tamis. 



   Le mode opératoire est le suivant: 
Du fait du mouvement de rota.tion du tambour, les matières sont entraînées à la manière connue pour retomber ensuite, ce qui provoque une action de mélange dans le plan transversal à l'axe du tambour. 



   Les cloisons obliques 2 déterminent lors de la ro- tation un déplacement des matières dans le sens de l'axe, vers l'ouverture de chargement 14, et un refoulement ou une retenue de ces matières pendant le temps pendant lequel la portion 4, de chaque cloison 2, disposée le plus près de ladi- te ouverture, se déplace du point le plus haut de la périphé- rie du tambour jusqu'au point le plus bas, après quoi, lors du mouvement de remontée subséquent, les matières se répandent de nouveau dans la direction de   l'axe,   donc se déplacent vers l'ouverture de décharge 9. Du fait de ce mouvement axial alternatif, les matières se trouvent mélangées dans le sens 

 <Desc/Clms Page number 4> 

 de la longueur, de sorte que, finalement, l'action de mélange s'exerce dans deux plans perpendiculaires.

   Comme l'ouverture 4 se trouve être à un endroit de la cloison qui, lorsque la hauteur de retenue des manières est, maximum, est arrivée au point le plus bas du tambour, il er,. résulte qu'une partie des matières passe à travers le passage 4 dans la chambre suivan- te. Il se produit a,insi un déplacement progressif des matiè- res vers l'ouverture de décharge 9, en même temps que le mé- lange se parfait dans chacune des chambres successives, jus- qu'à ce que finalement les matières sortent du tambour. 



   Dans le mode de réalisation des figures 1 et 2, les cloisons 2 sont constituées par une simple plaque de forme plane, de sorte que le point le plus bas de chaque cloison subit en cours de rotation une oscillation dans la direction de l'axe. 



   Les figures 3 et 4 montrent une autre disposition suivant laquelle chaque cloison se compose de deux parties pla.nes 2a et 2b fa,isant avec   l'axe   le même angle,. mais dans des sens opposés, de sorte que le point le plus bas de la cloison subit pendant un tour de rotation du tambour deux oscillations, provoquant deux refoulements correspondants des matières. Dans ce mode de réalisation, on peut, ou bien munir   seulement   l'une des parties 2a, 2b, d'un passage 4, ou bien munir respectivement lesdites parties de deux passa- ges de ce genre. 



   Les parois Ib et Ic formant tamis peuvent coagir avec des brosses   8,8, à   la. manière connue. 



   RESUME : 
L'invention a pour objet des perfectionnements ap- portés aux tambours mélangeurs à marche continue, montés de façon pivotante autour de leur axe géométrique, et munis

  Improvements made to continuously running mixing drums.



   The invention relates to a continuously running mixing drum, in which the material to be mixed is brought to direct, in addition, from its progressive path along the axis of the drum during rolling, a reciprocating movement. comes, therefore alternative in the. direction of this axis, as a result of which a perfect mixing action is achieved.



   The new drum according to the invention is charac- terized by the fact that, on the one hand, it is, as usual, mobile around its geometrical axis and provided at its

 <Desc / Clms Page number 2>

 respective ends of a loading opening and a discharge opening, and that, on the other hand, it is divided into a number of successive chambers by one or more dividing walls arranged obliquely with respect to the longitudinal axis, which chambers communicate with each other by means of openings made in the parts of said partitions closest to the loading opening of the drum.



   By constituting the wall of the drum in the form of a sieve, at least on the side of its outlet opening, the mixing device can at the same time be used for sieving.



   The drawing shows, by way of example, two embodiments of the new mixing device, in schematic views.



   Figure 1 is an axial section of a mixing and sieving machine equipped with the drum according to the invention.



   Figure 2 is a cross section taken on line 2-2 of Figure 1.



   Figures 3 and 4 are respectively axial and transverse sections of the same machine established according to the second embodiment.



   The drum 1 is mounted so as to pivot about its longitudinal and horizontal axis, using for example carrier rollers 13, and it can be driven in rotation by any suitable device. At one end is formed the loading opening 14 into which opens the conduit 3 of the loading device 7, which is provided with hoppers 6, 6a for the various materials to be mixed. At the other end the drum has a discharge opening 9.

 <Desc / Clms Page number 3>

 



   According to the invention, said drum is divided into several chambers 15 by transverse partitions 2 disposed obliquely with respect to its longitudinal axis. The perfection of the mixture increases with the number of partitions or said chambers. At the part of said partitions closest to the loading opening 14 are provided passages 4 putting the chambers 15 in communication with one another, passages whose radial height gradually decreases from their end situated forward in the direction of rotation to their rear end.



   Advantageously, the drum is provided, mainly towards the outlet opening 9, with one or more retaining rings 5, which protrude from the wall of said drum. In the embodiment of Figure 1, the front portion Ia of the drum is full, while the portion Ib, Ic. is produced in the form of a sieve.



   The operating mode is as follows:
Due to the rotational movement of the drum, the materials are entrained in the known manner and then fall back, which causes a mixing action in the plane transverse to the axis of the drum.



   The oblique partitions 2 determine during the rotation a displacement of the materials in the direction of the axis, towards the loading opening 14, and a discharge or a retention of these materials during the time during which the portion 4, of each partition 2, placed closest to said opening, moves from the highest point of the periphery of the drum to the lowest point, after which, during the subsequent upward movement, the materials are spread again in the direction of the axis, thus moving towards the discharge opening 9. As a result of this reciprocating axial movement, the materials are mixed in the direction

 <Desc / Clms Page number 4>

 length, so that ultimately the mixing action is exerted in two perpendicular planes.

   As the opening 4 happens to be at a place in the partition which, when the height of restraint of the manners is, maximum, arrived at the lowest point of the drum, it er ,. As a result, part of the material passes through passage 4 into the next chamber. A gradual displacement of the materials takes place towards the discharge opening 9, at the same time as the mixture is perfected in each of the successive chambers, until finally the materials leave the drum. .



   In the embodiment of Figures 1 and 2, the partitions 2 are formed by a simple plate of planar shape, so that the lowest point of each partition undergoes during rotation an oscillation in the direction of the axis.



   Figures 3 and 4 show another arrangement in which each partition is composed of two pla.nes parts 2a and 2b fa, izing with the axis the same angle. but in opposite directions, so that the lowest point of the partition undergoes during one revolution of the drum two oscillations, causing two corresponding upsets of the materials. In this embodiment, it is possible either to provide only one of the parts 2a, 2b with a passage 4, or to provide said parts respectively with two passages of this type.



   The walls Ib and Ic forming a screen can coact with brushes 8,8, à la. known manner.
