Description

Concasseur rotatif à tambour  Rotary drum crusher
La présente invention concerne un concasseur rotatif à tambour.  The present invention relates to a rotary drum crusher.
Le domaine de l'invention est celui du concassage pour réduire la taille de corps solides.  The field of the invention is that of crushing to reduce the size of solid bodies.
Actuellement, on utilise des machines pourvues de mâchoires, de marteaux ou bien de galets. Le principe de fonctionnement de ces concasseurs est l'écrasement de corps solides pour provoquer leurs ruptures en plusieurs fragments.  Currently, machines are used with jaws, hammers or pebbles. The operating principle of these crushers is the crushing of solid bodies to cause their breaks in several fragments.
Il s'agit là d'une solution satisfaisante pour de nombreux matériaux. Elle présente cependant toutes les limitations que l'homme du métier a répertoriées pour certains matériaux. A titre d'exemple, une proportion importante du corps solide traité peut se voir réduite en poussière, et, par conséquent, devenir inutilisable si ce n'était pas là le but recherché. On pense notamment aux agrégats tel que le verre cellulaire.  This is a satisfactory solution for many materials. However, it has all the limitations that the skilled person has listed for certain materials. For example, a large proportion of the solid body treated can be reduced to dust, and therefore become unusable if that is not the goal. Aggregates such as cellular glass are particularly thought of.
On connaît ainsi le document DE 41 00 080 qui décrit un appareil de concassage et de séparation. Cet appareil comporte un moyen de pression en appui sur un réceptacle. Ce réceptacle prend la forme d'un tambour dont la paroi est ajourée, cette paroi incurvée étant mobile selon l'axe du tambour. Le moyen de pression figure à l'intérieur du tambour et il comprend un rouleau solidaire d'un levier.  DE 41 00 080, which describes a crushing and separating apparatus, is thus known. This apparatus comprises a pressure means bearing on a receptacle. This receptacle takes the form of a drum whose wall is perforated, this curved wall being movable along the axis of the drum. The pressure means is inside the drum and comprises a roller integral with a lever.
Ce rouleau n'est donc pas libre de circuler dans le tambour et là encore une proportion importante du corps solide traité peut se voir réduite en poussière.  This roller is not free to circulate in the drum and again a significant proportion of the solid body treated can be reduced to dust.
La présente invention a ainsi pour objet de réduire la taille de corps solides en optimisant la proportion des fragments produits lors du traitement de ces corps.  The object of the present invention is therefore to reduce the size of solid bodies by optimizing the proportion of fragments produced during the treatment of these bodies.
Selon l'invention, un concasseur comprend un moyen de pression en appui sur un réceptacle, concasseur prévu pour cisailler des corps solides entre ce moyen de pression et le réceptacle, celui-ci se présentant comme un tambour dont la paroi incurvée est ajourée, cette paroi incurvée étant mobile en rotation selon un axe de référence ; de plus, le moyen de pression prend la forme d'un chariot comportant deux rouleaux mobiles, ce chariot étant monté libre dans le tambour.  According to the invention, a crusher comprises a pressure means resting on a receptacle, a crusher provided for shearing solid bodies between this pressure means and the receptacle, the latter being in the form of a drum whose curved wall is perforated, this curved wall being movable in rotation along a reference axis; in addition, the pressure means takes the form of a carriage having two movable rollers, this carriage being freely mounted in the drum.
Il s'ensuit que les corps solides qui sont cisaillés entre le moyen de pression et le réceptacle au lieu d'y être écrasés donnent lieu à une production de poussière extrêmement réduite lorsque le matériau des corps traités est friable. It follows that the solid bodies which are sheared between the pressure medium and the receptacle instead of being crushed there give rise to a production extremely reduced dust when the material of the treated bodies is friable.
Avantageusement, l'axe de référence est incliné par rapport à l'horizontale.  Advantageously, the reference axis is inclined relative to the horizontal.
Par ailleurs, le chariot est éventuellement muni d'un bras supportant un troisième rouleau.  Furthermore, the carriage is optionally provided with an arm supporting a third roller.
Avantageusement, l'un des flancs du tambour a une ouverture permettant l'introduction des corps solides.  Advantageously, one of the sides of the drum has an opening allowing the introduction of solid bodies.
Par ailleurs, le concasseur comprend un moyen de guidage pour maintenir le moyen de pression au sein du tambour.  Furthermore, the crusher comprises guiding means for maintaining the pressure means within the drum.
Il s'agit là d'un moyen simple de cantonner le moyen de pression dans le réceptacle.  This is a simple way of confining the pressure medium in the receptacle.
A titre d'exemple, la paroi incurvée est formée d'une pluralité d'entretoises régulièrement espacées.  For example, the curved wall is formed of a plurality of regularly spaced spacers.
Ainsi, on calibre au moins en partie les fragments produits.  Thus, at least some of the fragments produced are calibrated.
Le tambour peut être monté sur des galets assujettis à un bâti.  The drum can be mounted on rollers subject to a frame.
L'application avantageuse du concasseur vise le concassage des corps solides en verre cellulaire.  The advantageous application of the crusher is the crushing of solid bodies made of cellular glass.
La présente invention apparaîtra maintenant avec plus de détails dans le cadre de la description qui suit d'exemples de réalisation donnés à titre illustratif en se référant aux figures annexées qui représentent :  The present invention will now appear in greater detail in the context of the following description of exemplary embodiments given by way of illustration with reference to the appended figures which represent:
- la figure 1 , représente une vue en coupe du concasseur,  FIG. 1 represents a sectional view of the crusher,
- îa figure 2 représente une vue en perspective du concasseur.  Figure 2 shows a perspective view of the crusher.
Les éléments présents dans les deux figures sont affectés d'une seule et même référence.  The elements present in the two figures are assigned a single reference.
En référence aux figures, le concasseur comprend un réceptacle prenant dans le cas présent la forme d'un tambour 100 dont la paroi incurvée 101 est cylindrique. Cette paroi est mobile en rotation suivant un axe de référence 102 qui est ici l'axe de révolution du tambour 100.  With reference to the figures, the crusher comprises a receptacle taking in this case the shape of a drum 100 whose curved wall 101 is cylindrical. This wall is rotatable along a reference axis 102 which is the axis of revolution of the drum 100.
Ce tambour 100 comprend également deux flancs latéraux prenant les formes respectives d'un anneau 103 et d'un disque 104. Une goulotte 105 légèrement inclinée débouche dans le tambour 100 par le centre évidé de l'anneau 103.  This drum 100 also comprises two lateral flanks taking the respective shapes of a ring 103 and a disc 104. A slightly inclined chute 105 opens into the drum 100 through the recessed center of the ring 103.
Cette goulotte 105 permet l'alimentation par gravité des corps solides à l'intérieur du tambour 100. Une légère inclinaison par rapport à l'horizontale (de l'ordre de 10%) de l'axe de référence 102 favorise la répartition des corps solides 126 le long de la paroi incurvée 101. This chute 105 allows the gravity feed of the solid bodies inside the drum 100. A slight inclination with respect to the horizontal (of the order of 10%) of the reference axis 102 promotes the distribution of the solid bodies 126 along the curved wall 101.
La rotation du tambour 100 suivant l'axe de référence 102 est réalisée par un sous-ensemble mécanique.  The rotation of the drum 100 along the reference axis 102 is performed by a mechanical subassembly.
D'une part deux galets 106, 107 reliés roulants à un bâti 109 supportent l'anneau 103.  On the one hand, two rollers 106, 107 connected to a frame 109 support the ring 103.
D'autre part, un arbre 110 aligné sur l'axe de référence 102, solidaire du disque 104 traverse un palier 108 lui aussi fixé sur le bâti 109.  On the other hand, a shaft 110 aligned on the reference axis 102, secured to the disk 104 passes through a bearing 108 also fixed on the frame 109.
Une grille est ici réalisée avec une pluralité d'entretoises 112 fixées sur les flancs 103, 104. Ces entretoises en forme de plaque sont disposées radialement autour de l'axe de référence 02 et régulièrement espacées.  A grid is here made with a plurality of spacers 112 fixed on the sidewalls 103, 104. These plate-shaped spacers are arranged radially around the reference axis 02 and regularly spaced.
Les bords internes de ces plaques 112 définissent Sa paroi cylindrique 101. Les arêtes de ces bords internes sont anguleuses pour améliorer le cisaillement des corps solides. Autrement dit, la section radiale au niveau du bord interne est sensiblement rectangulaire.  The inner edges of these plates 112 define its cylindrical wall 101. The edges of these inner edges are angular to improve the shearing of the solid bodies. In other words, the radial section at the inner edge is substantially rectangular.
Pour faciliter la compréhension de la figure 2, il est représenté uniquement quelques entretoises 112 et un rouleau 122 dont la fonction sera précisée ultérieurement. Bien entendu, cette paroi cylindrique 101 ajourée peut prendre une multitude d'autres formes, à titre d'exemple une pluralité d'anneaux minces identiques et coaxiaux, espacés régulièrement entre les flancs 103, 104.  To facilitate the understanding of Figure 2, it shows only a few spacers 112 and a roller 122 whose function will be specified later. Of course, this perforated cylindrical wall 101 can take a multitude of other forms, for example a plurality of identical and coaxial thin rings regularly spaced between the flanks 103, 104.
La rotation du tambour 100 peut être réalisée par un quelconque actionneur connu de l'homme du métier pour entraîner l'arbre 110.  The rotation of the drum 100 can be performed by any actuator known to those skilled in the art for driving the shaft 110.
En revenant sur la figure 1 , le concasseur comprend également un moyen de pression 120, positionné en appui à l'intérieur du tambour 100, sur sa paroi cylindrique 101. Ce moyen de pression 120 prend ici la forme d'un chariot 121 muni de deux rouleaux 122, 123 mobiles dont les axes sont parallèles à l'axe de référence 102. Ce chariot mobile 121 peut être muni d'un bras 125 mobile supportant un troisième rouleau 124 lui aussi parallèle à l'axe de référence 102.  Referring again to FIG. 1, the crusher also comprises a pressure means 120, positioned in abutment inside the drum 100, on its cylindrical wall 101. This pressure means 120 here takes the form of a carriage 121 provided with two movable rollers 122, 123 whose axes are parallel to the reference axis 102. This mobile carriage 121 may be provided with a mobile arm 125 supporting a third roller 124 also parallel to the reference axis 102.
Sur la figure 1 , le tambour 100 tourne suivant le sens inverse des aiguilles d'une montre. De ce fait, ce troisième rouleau 124 roule sur les corps solides 126 introduit dans le tambour 100 ce qui provoque un mouvement saccadé du bras 125. Ce mouvement saccadé du bras 125 produit un effet marteau du troisième rouleau 124. Bien entendu, le moyen de pression 120 peut être réalisé par un unique rouleau dont l'axe est parallèle à l'axe de rotation 102 du tambour 100 comme il peut être réalisé par une pluralité de rouleaux. L'effort exercé par le moyen de pression 120 sur le tambour 100 est ici dû à la gravité. Cependant, cet effort peut être exercé par un organe mécanique, par exemple du type ressort, intercalé entre le bâti 109 et le moyen de pression 120. In Figure 1, the drum 100 rotates in a counterclockwise direction. Therefore, this third roller 124 rolls on the solid bodies 126 introduced into the drum 100 which causes a jerky movement of the arm 125. This jerky movement of the arm 125 produces a hammering effect of the third roller 124. Of course, the means of pressure 120 may be made by a single roller whose axis is parallel to the axis of rotation 102 of the drum 100 as it can be achieved by a plurality of rollers. The force exerted by the pressure means 120 on the drum 100 is here due to gravity. However, this force can be exerted by a mechanical member, for example of the spring type, interposed between the frame 109 and the pressure means 120.
Dans notre exemple, le moyen de pression 120 est monté libre dans le tambour 100. De ce fait, un moyen de guidage est nécessaire pour le maintenir à l'intérieur du tambour 100. Ce moyen de guidage peut être réalisé par exemple avec un rail circulaire 1 1 1 positionné à l'intérieur du tambour 100.  In our example, the pressure means 120 is freely mounted in the drum 100. As a result, a guide means is required to hold it inside the drum 100. This guide means can be made for example with a rail circular 1 1 1 positioned inside the drum 100.
Ce rail 1 1 1 centré sur l'axe de référence 102, parallèle aux flancs 103, 104 et fait saillie de la paroi incurvée 101. Il faut alors prévoir une gorge 1 13 dans les rouleaux 122 (voir figure 2).  This rail 1 1 1 centered on the reference axis 102, parallel to the sidewalls 103, 104 and protrudes from the curved wall 101. It is then necessary to provide a groove 1 13 in the rollers 122 (see Figure 2).
Les corps solides 126 sont introduits à l'intérieur du tambour par la goulotte 105, ils tombent sur la paroi cylindrique 101 de ce tambour 100 en rotation et sont déplacés en direction d'un des rouleaux 122, 123, 24. Ces corps solides 126 se coincent chacun entre un rouleau 122, 123 et le tambour 100 avant d'être cisaillés et passé à travers les entretoises 1 12 pour tomber dans un collecteur 127. La géométrie de la surface ajourée conditionne le calibrage des corps solides cisaillés.  The solid bodies 126 are introduced inside the drum by the chute 105, they fall on the cylindrical wall 101 of the drum 100 in rotation and are moved towards one of the rollers 122, 123, 24. These solid bodies 126 are each wedged between a roller 122, 123 and the drum 100 before being sheared and passed through the spacers 1 12 to fall into a manifold 127. The geometry of the perforated surface conditions the calibration of the sheared solid bodies.
Le concasseur selon l'invention est destiné à réduire la taille de corps solides. Il trouve une application particulièrement avantageuse pour le verre cellulaire.  The crusher according to the invention is intended to reduce the size of solid bodies. It finds a particularly advantageous application for cellular glass.
Les exemples de réalisation de l'invention présentés ci-dessus ont été choisis pour leur caractère concret. Il ne serait cependant pas possible de répertorier de manière exhaustive tous les modes de réalisation que recouvre cette invention. En particulier, tout moyen décrit peut-être remplacé par un moyen équivalent sans sortir du cadre de la présente invention.  The embodiments of the invention presented above have been chosen for their concrete nature. It would not be possible, however, to exhaustively list all the embodiments covered by this invention. In particular, any means described may be replaced by equivalent means without departing from the scope of the present invention.
