Abstract

The machine consists of a horizontal or slightly inclined rotary drum (10) made up of a number of sections (10a - 10e) with apertures (26) increasing in size in the direction of the flow through the drum. Each drum section has a truncated conical wall which converges in the direction of the flow, with the apertures in the shape of slots of increasing size in the same direction. Each drum section is in the form of a separate module which can be detached from the adjacent sections, to which it is connected by bolted flanges (14, 16). The end flanges of the first and last drum sections are supported by roller bearings (18, 20). The inside of each drum section has guide vanes, and the slots are inclined relative to the direction of travel.

Description

La présente invention concerne une machine de triage d'objets solides comprenant un ensemble de tambours rotatifs horizontaux et légèrement inclinés traversé longitudinalement par les objets à trier et dont la paroi est criblée de trous de triage calibrés, dans laquelle le tambour est constitué, dans le sens longitudinal, de différentes sections, le calibre des trous de triage augmentant d'une section à l'autre dans le sens de la progression des objets à trier.The present invention relates to a sorting machine for solid objects comprising a set of horizontal and slightly inclined rotary drums traversed longitudinally by the objects to be sorted and the wall of which is riddled with calibrated sorting holes, in which the drum is made, in the longitudinal direction, of different sections, the size of the sorting holes increasing from one section to another in the direction of progression of the objects to be sorted.

Quoique n'y étant pas limitée, l'invention vise plus particulièrement une machine pour trier les engins de broyage formant la charge broyante d'un broyeur horizontal, tels que ceux utilisés en cimenterie ou dans l'industrie minière pour broyer et concasser les minerais.Although not limited thereto, the invention relates more particularly to a machine for sorting the grinding machines forming the grinding load of a horizontal mill, such as those used in cement works or in the mining industry for grinding and crushing ores .

Il est bien connu que la composition de la charge broyante c'est à dire la quantité, la dimension des engins broyants ainsi que leur répartition influence grandement le rendement et la qualité du broyage.It is well known that the composition of the grinding load, that is to say the quantity, the size of the grinding machines as well as their distribution greatly influences the yield and the quality of the grinding.

L'usure des engins broyants modifie constamment, en cours de service, les conditions idéales du départ d'où l'intérêt de pouvoir réaliser un tri rapide de la charge broyante, afin de permettre son reconditionnement optimal.The wear and tear of the grinding media constantly changes, during service, the ideal conditions of departure, hence the advantage of being able to quickly sort the grinding load, in order to allow its optimal reconditioning.

Cette opération de tri n'est envisageable fréquemment, que si elle peut s'effectuer rapidement, sans causer une augmentation de la durée des arrêts normaux du broyeur.This sorting operation can only be envisaged frequently, if it can be carried out quickly, without causing an increase in the duration of the normal stops of the mill.

Ceci nécessite par conséquent, que la trieuse ait un débit de tri important.This therefore requires that the sorter has a high sorting rate.

On connaît différents types de machines pour réaliser le triage des engins de broyage. La machine décrite dans le document BE-834187 comporte essentiellement deux cylindres légèrement inclinés par rapport à l'horizontale qui définissent entre eux une fente de triage dont la largeur augmente d'un côté à l'autre. Ces deux cylindres tournent en sens inverse, chacun vers l'extérieur. Les engins de broyage sont déversés dans la fente de triage du côté de la largeur minimale de celle-ci. Les engins progressent sous l'effet de la rotation et de l'inclinaison des cylindres et tombent à travers la fente dans différentes trémie de récupération dès que la largeur de la fente dépasse la section minimale d'un engin à trier.Different types of machines are known for sorting grinding machines. The machine described in document BE-834187 essentially comprises two cylinders slightly inclined by with respect to the horizontal which define between them a sorting slot whose width increases from one side to the other. These two cylinders rotate in opposite directions, each outward. The grinding machines are poured into the sorting slot on the side of the minimum width thereof. The machines progress under the effect of the rotation and the inclination of the cylinders and fall through the slot in different recovery hoppers as soon as the width of the slot exceeds the minimum section of a sorting machine.

Cette machine permet un bon triage à condition que les engins broyants progressent en chapelet un par un le long des cylindres. Dans ces conditions, le débit de triage est toutefois très faible.This machine allows good sorting provided that the grinding machines progress in strings one by one along the cylinders. Under these conditions, the sorting throughput is however very low.

Une autre machine est celle qui est décrite dans le préambule et qui fait l'objet de la demande de brevet français No. 2248884. La forme des trous de triage correspond en général à celle des engins broyants. Pour favoriser le mouvement longitudinal des engins à trier, le tambour est, de préférence, incliné vers le haut dans le sens de la progression. Au fur et à mesure que les engins à trier avancent à travers le tambour et trouvent un passage plus grand que leur section minimale, ils traversent ce trou de triage pour tomber dans une trémie de récupération placée en dessous du tambour.Another machine is that which is described in the preamble and which is the subject of French patent application No. 2248884. The shape of the sorting holes generally corresponds to that of grinding machines. To promote the longitudinal movement of the sorting machines, the drum is preferably inclined upwards in the direction of progression. As the sorting machines advance through the drum and find a passage larger than their minimum section, they pass through this sorting hole to fall into a recovery hopper placed below the drum.

Cette machine souffre du handicap que les engins à trier restent facilement coincés dans les trous de triage qui s'obstruent de cette manière, ce qui, non seulement réduit la surface de triage, donc le débit, mais, en outre, diminue la précision de triage, car les engins à trier progressent trop vite vers la sortie vu que les trous de leur calibre sont obstrués.This machine suffers from the handicap that the sorting machines easily get stuck in the sorting holes which are obstructed in this way, which not only reduces the sorting surface and therefore the throughput, but also decreases the precision of sorting, because the sorting machines progress too quickly towards the exit since the holes of their caliber are obstructed.

Le but de la présente invention est de prévoir une machine de triage perfectionnée qui ne présente pas les inconvénients précités, autrement dit, une machine qui est dotée d'une bonne précision de triage et qui fonctionne à un débit de triage élevé.The object of the present invention is to provide an improved sorting machine which does not have the disadvantages mentioned above, in other words, a machine which has good sorting precision and which operates at a high sorting rate.

Pour atteindre cet objectif, l'invention propose une machine de triage du genre défini dans le préambule qui est caractérisée en ce que chaque section comporte une paroi tronconique convergeant dans le sens de progression des objets et en ce que les trous de triage sont en forme de fentes s'élargissant dans le sens de progression à travers le tambour.To achieve this objective, the invention provides a sorting machine of the kind defined in the preamble which is characterized in that each section has a frustoconical wall converging in the direction of progression of the objects and in that the sorting holes are shaped slits widening in the direction of progression through the drum.

Le fait que les différentes sections aient un profil tronconique contribue à favoriser le classement des engins broyants en couches superposées, les gros engins occupant préférentiellement les couches supérieures et les plus petits se retrouvant le long des parois, ce qui facilite leur évacuation, en premier lieu, par les trous calibrés. Cette disposition a pour effet d'augmenter considérablement l'efficacité du tri.The fact that the different sections have a frustoconical profile contributes to favoring the classification of the grinding machines in superimposed layers, the large machines preferably occupying the upper layers and the smaller ones being found along the walls, which facilitates their evacuation, first of all , through the calibrated holes. This arrangement has the effect of considerably increasing the efficiency of sorting.

Le fait que les fentes de triage s'élargissent en direction de la sortie non seulement permet de déterminer la gamme de dimensions à trier mais, et surtout, évite un blocage de objets dans les trous de triage et, par conséquent, une obstruction de ceux-ci.The fact that the sorting slots widen towards the exit not only makes it possible to determine the range of dimensions to be sorted but, above all, avoids blocking of objects in the sorting holes and, consequently, an obstruction of those -this.

Le tambour est avantageusement un tambour modulaire dont chaque section est une unité indépendante fixée, de façon amovible, à la section adjacente.The drum is advantageously a modular drum of which each section is an independent unit fixed, in a removable manner, to the adjacent section.

Chaque section peut comporter à chacune des ses extrémités une bride annulaire pour être boulonnée sur la bride adjacente de la section voisine.Each section may have an annular flange at each of its ends to be bolted to the adjacent flange of the neighboring section.

Au moins les deux brides extérieures à l'entrée et à la sortie du tambour peuvent être conçues comme surface de support et de roulement et être portées par des galets de support et de roulement.At least the two external flanges at the inlet and at the outlet of the drum can be designed as a support and rolling surface and be carried by support and rolling rollers.

Selon un autre aspect de l'invention, les parois des trous de triage sont biseautées et divergent de l'intérieur vers l'extérieur dans la direction de passage des objets à travers les trous de triage.According to another aspect of the invention, the walls of the sorting holes are bevelled and diverge from inside to outside in the direction of passage of objects through the sorting holes.

Ces trous de triage sont de préférence inclinés par rapport au sens de progression.These sorting holes are preferably inclined relative to the direction of progression.

Selon un autre aspect très important de l'invention, des tôles de guidage sont fixées à l'intérieur de chacune des sections, à peu près perpendiculairement à la paroi et décrivant une spirale suivant un angle qui varie avec le diamètre des corps à trier de façon à guider les objets dans le sens de leur progression.According to another very important aspect of the invention, guide plates are fixed inside each of the sections, roughly perpendicular to the wall and describing a spiral at an angle which varies with the diameter of the bodies to be sorted. in order to guide the objects in the direction of their progression.

La machine comporte également une trémie de déversement compartimentée s'étendant sur toute la longueur du tambour en dessous de celui-ci.The machine also includes a compartmentalized spill hopper extending over the entire length of the drum below it.

D'autres particularités de l'invention ressortiront de la description détaillée d'un mode de réalisation avantageux, présenté ci-dessous à titre d'illustration et d'exemple, en référence aux dessins annexés dans lesquels :

  • la Figure 1 montre de façon schématique, une vue latérale d'un tambour de triage;
  • la Figure 2 montre les détails d'un trou de triage;
  • la Figure 3 montre une section suivant le plan de coupe III-III de la Figure 2;
  • la Figure 4 montre schématiquement une vue d'une machine de triage selon la présente invention.
Other particular features of the invention will emerge from the detailed description of an advantageous embodiment, presented below by way of illustration and example, with reference to the appended drawings in which:
  • Figure 1 schematically shows a side view of a sorting drum;
  • Figure 2 shows the details of a sorting hole;
  • Figure 3 shows a section along the section plane III-III of Figure 2;
  • Figure 4 schematically shows a view of a sorting machine according to the present invention.

Le tambour de triage représenté sur les Figures 1 et 4 et désigné dans son ensemble par la référence 10 est constitué de différentes, en l'occurrence, cinq sections 10a, 10b, 10c, 10d et 10e, reliées les unes aux autres et traversées axialement par les engins à trier.The sorting drum shown in Figures 1 and 4 and designated as a whole by the reference 10 consists of different, in this case, five sections 10a, 10b, 10c, 10d and 10e, connected to each other and crossed axially by sorting machines.

Le tambour est en principe disposé horizontalement mais, suivant les conditions de fonctionnement, pourrait être légèrement incliné d'un côté ou d'un autre. Chaque section comporte une paroi tronconique convergeant dans le sens de la progression des engins à trier, ceux-ci étant introduits dans la section 10a à l'aide d'un dispositif d'alimentation approprié 12 (voir Figure 4) par exemple un couloir vibrant.The drum is in principle arranged horizontally but, depending on the operating conditions, could be tilted slightly on one side or another. Each section has a frustoconical wall converging in the direction of progression of the sorting machines, these being introduced into section 10a using an appropriate feeding device 12 (see Figure 4) for example a vibrating corridor.

Chaque section tronconique peut comporter, du côté amont et du côté aval, une bride annulaire 14 respectivement 16 par lesquelles la section est boulonnée à la section adjacente. Les différentes sections peuvent ainsi être remplacées individuellement voire être interchangées.Each frustoconical section may comprise, on the upstream side and on the downstream side, an annular flange 14 respectively 16 by which the section is bolted to the adjacent section. The different sections can thus be replaced individually or even be interchanged.

Le tambour 10 repose par ses extrémités sur des galets 18 et 20 et est entraîné en rotation autour de son axe longitudinal par un moteur non représenté à vitesse variable. Cette vitesse peut être adaptée aux conditions de triage afin d'avoir une influence sur la précision et le débit de triage.The drum 10 rests at its ends on rollers 18 and 20 and is driven in rotation about its longitudinal axis by a motor not shown at variable speed. This speed can be adapted to the sorting conditions in order to have an influence on the accuracy and the sorting rate.

S'il s'avère nécessaire, il est possible de prévoir également un support à galets dans la région médiane du tambour 10.If necessary, it is also possible to provide a roller support in the middle region of the drum 10.

Le tambour 10 peut se trouver à l'intérieur d'un châssis 22 (voir Figure 4) qui peut être fermé pour réduire les émissions de bruits et permettre la réalisation d'un système de dépoussiérage. En dessous du tambour 10 se trouve une trémie de déversement compartimentée 24 comprenant un nombre de compartiments correspondant au nombre de sections.The drum 10 can be located inside a frame 22 (see Figure 4) which can be closed to reduce noise emissions and allow the creation of a dust collection system. Below the drum 10 is a compartmentalized discharge hopper 24 comprising a number of compartments corresponding to the number of sections.

Les parois des différentes sections tronconiques 10a, 10b, 10c, 10d et 10e sont criblées de trous de triage calibrés 26. Pour des raisons de simplification, les trous de triage n'ont été représentés sur les figures 1 et 4 que sur la dernière section 10e. Les trous d'une même section ont, de préférence, tous la même forme et la même surface. En revanche, la surface des trous de triage 26 augmente d'une section à l'autre, ceci dans le sens de progression de la charge à trier.The walls of the different frustoconical sections 10a, 10b, 10c, 10d and 10e are screened with calibrated sorting holes 26. For reasons of simplification, the sorting holes have only been shown in FIGS. 1 and 4 on the last section 10th. The holes of the same section preferably have all the same shape and the same surface. On the other hand, the surface of the sorting holes 26 increases from one section to another, this in the direction of progression of the load to be sorted.

Selon l'une des particularités de l'invention, les trous de triage 26 ont la forme d'une fente allongée dont l'axe longitudinal est incliné par rapport à l'axe A du tambour et par rapport à un plan diamétral de celui-ci.According to one of the features of the invention, the sorting holes 26 have the form of an elongated slot whose longitudinal axis is inclined relative to the axis A of the drum and relative to a diametral plane of the latter. this.

Comme le montre la Figure 2, chaque trou de triage est, en outre, en forme de gouttelette, c'est à dire que la largeur des trous de triage augmente dans le sens de la progression de la charge à trier. Les extrémités opposées des trous de triage 26 sont, de préférence, arrondies.As shown in FIG. 2, each sorting hole is also in the form of a droplet, that is to say that the width of the sorting holes increases in the direction of progression of the load to be sorted. The opposite ends of the sorting holes 26 are preferably rounded.

Les parois définissant les trous 26 ne sont pas perpendiculaires à la surface, mais, comme le montre la Figure 3, légèrement obliques, divergeant de l'intérieur du tambour vers l'extérieur. Grâce à cette forme on est sûr que les engins à trier ne restent pas coincés dans les trous 26 une fois que le bord intérieur des trous 26 permet le passage des engins.The walls defining the holes 26 are not perpendicular to the surface, but, as shown in Figure 3, slightly oblique, diverging from the inside of the drum to the outside. Thanks to this shape, it is certain that the sorting machines do not get stuck in the holes 26 once the inner edge of the holes 26 allows the machines to pass through.

A l'intérieur de chaque section sont disposées des tôles de guidage 28 (voir Figures 1 et 4). Ces tôles 28 dont la hauteur est fonction de la dimension des engins à trier sont inclinées en spirale afin de favoriser et de contrôler la progression de la charge lors de la rotation du tambour. Ces tôles 28 ont donc une grande influence sur la précision de triage ainsi que sur le rendement de la machine. L'inclinaison des tôles de guidage 28 correspond, de préférence, à celle des trous de triage 26 afin que ceux-ci soient masqués le moins possible par les tôles 28.Inside each section are arranged guide plates 28 (see Figures 1 and 4). These sheets 28 whose height is a function of the size of the sorting machines are inclined in a spiral in order to promote and control the progress of the load during the rotation of the drum. These sheets 28 therefore have a great influence on the sorting precision as well as on the efficiency of the machine. The inclination of the guide plates 28 preferably corresponds to that of the sorting holes 26 so that these are hidden as little as possible by the plates 28.

La première section 10a qui reçoit la charge à trier par le dispositif d'alimentation 12 est en principe un compartiment d'alimentation et de répartition de la charge. La seconde section peut servir à éliminer les engins devenus trop petits et non utilisables par la suite, ainsi que les corps étrangers et les résidus de la matière à broyer apportée par la charge. Il est toutefois possible que toutes ces fonctions puissent être accomplies par la première section 10a.The first section 10a which receives the load to be sorted by the feed device 12 is in principle a feed and load distribution compartment. The second section can be used to remove gear that has become too small and cannot be used later, as well as foreign bodies and residues of the material to be ground brought in by the charge. However, it is possible that all of these functions can be accomplished by the first section 10a.

Les tambours suivants effectuent le triage proprement dit des engins de broyage par classes de dimensions et par ordre grandissant de l'entrée vers la sortie. En supposant que le calibre des tous de triage 26 augmente progressivement des sections 10c, 10d et 10e il est possible de trier quatre calibres différents d'engins de broyage, à savoir les trois calibres triés respectivement par les sections 10c, 10d et 10e, ainsi que les gros calibres qui quittent la machine par la sortie.The following drums perform the actual sorting of the grinding machines by size classes and in ascending order from the inlet to the outlet. Assuming that the size of all sorting units 26 gradually increases in sections 10c, 10d and 10e, it is possible to sort four different sizes of grinding machines, namely the three sizes sorted respectively by sections 10c, 10d and 10e, as well than large calibers that leave the machine through the outlet.

Etant donné que les différentes sections sont interchangeables, il est possible de doubler une section en fonction de la charge à trier. Il faut noter également que le choix de cinq sections n'est qu'un exemple de réalisation et qu'il est parfaitement possible d'augmenter ou de diminuer le nombre de sections suivant les besoins. La machine est, par conséquent, dotée d'une grande flexibilité d' adaptation.Since the different sections are interchangeable, it is possible to double a section depending on the load to be sorted. It should also be noted that the choice of five sections is only an example of an embodiment and that it is perfectly possible to increase or decrease the number of sections as required. The machine is therefore endowed with great flexibility of adaptation.

Compte tenu de la forme particulière des trous, les rangées de trous peuvent être disposées en quinconce les unes par rapport aux autres, ce qui augmente le nombre de trous ainsi que la surface de triage.Given the particular shape of the holes, the rows of holes can be staggered with respect to each other, which increases the number of holes as well as the sorting surface.
