Description
La présente invention a pour objet un dispositif de séparation, par pressage et extrusion, des deux matériaux composant certains déchets industriels, en vue de la récupération d'au moins l'un d'eux, par exemple le caoutchouc et la nappe textile ou métallique des pneumatiques usés. The subject of the present invention is a device for separating, by pressing and extrusion, the two materials making up certain industrial waste, with a view to recovering at least one of them, for example rubber and the textile or metallic web. used tires.
On a déjà proposé, dans le document EP 0.018.664, un procédé et un dispositif pour le broyage de déchets en caoutchouc utilisant la pression et le fluage. EP 0.018.664 has already proposed a method and a device for grinding rubber waste using pressure and creep.
L'un des dispositifs décrits est constitué d'une enceinte cylindrique perforée radialement dans laquelle se déplace axialement un outil de pression, le pneumatique à traiter étant préalablement introduit autour dudit outil dans ladite enceinte. Ce dispositif présente l'inconvénient de ne pas permettre d'atteindre des cadences élevées de traitement, et de plus de nécessiter une machine par diamètre de pneumatique traité. One of the devices described consists of a radially perforated cylindrical enclosure in which a pressure tool moves axially, the tire to be treated being previously introduced around said tool in said enclosure. This device has the drawback of not making it possible to achieve high treatment rates, and moreover of requiring a machine for each diameter of the tire treated.
Un autre dispositif décrit dans ce document, utilise deux tambours tournant en contre-rotation, les surfaces cylindriques desdits tambours comportant des ouvertures dans lesquelles le caoutchouc flue sous la pression exercée. Another device described in this document uses two drums rotating in counter-rotation, the cylindrical surfaces of said drums having openings in which the rubber flows under the pressure exerted.
Ce dispositif, s'il permet des cadences plus élevées, présente toutefois certains inconvénients, car d'une part il ne permet pas de séparer le caoutchouc de la nappe métallique ou textile, le résultat obtenu étant plus proche d'un broyage que d'une séparation des différents matériaux, et d'autre part, en cas de surépaisseur de la matière à broyer, par exemple les tringles des pneumatiques de poids-lourds, le dispositif ne peut que caler ou casser. This device, if it allows higher rates, has however certain drawbacks, because on the one hand it does not allow the rubber to be separated from the metal or textile sheet, the result obtained being closer to grinding than to a separation of the different materials, and on the other hand, in the event of excess thickness of the material to be ground, for example the rods of the tires of heavy goods vehicles, the device can only stall or break.
De plus les moyens mis en oeuvre ne permettent pas l'évacuation de la matière récupérée.In addition, the means used do not allow the evacuation of the recovered material.
La présente invention vise à remédier à ces inconvénients en proposant un dispositif de séparation, par pressage et extrusion, en vue de leur récupération, des deux matériaux composant certains déchets industriels, permettant d'obtenir une séparation effective des matériaux récupérables. The present invention aims to remedy these drawbacks by proposing a device for separation, by pressing and extrusion, with a view to their recovery, of the two materials making up certain industrial waste, making it possible to obtain effective separation of the recoverable materials.
Un dispositif selon l'invention se caractérise essentiellement en ce qu'il comporte d'une part deux cylindres superposés d'axes parallèles, susceptibles d'être écartés l'un de l'autre et maintenus fermement dans une position donnée, dont l'un est entraîné en rotation à une vitesse variable, et qui sont essentiellement constitués chacun d'une ossature robuste et évidée recouverte extérieurement d'une virole fine percée d'une pluralité d'orifices régulièrement répartis; en ce qu il comporte d'autre part, au droit de la région de rapprochement desdits cylindres, en amont de ceux-ci, un convoyeur vibrant d'alimentation; et en ce qu'il comporte enfin, en aval desdits cylindres, deux lames racleuses horizontales, une pour chacun des cylindres, dont les bords de coupe entrent en contact avec les viroles desdits cylindres, au plus près de leur région de rapprochement. A device according to the invention is essentially characterized in that it comprises on the one hand two superimposed cylinders of parallel axes, capable of being spaced from one another and firmly held in a given position, the one is driven in rotation at a variable speed, and which essentially consist each of a robust and hollowed-out framework covered externally with a fine ferrule pierced with a plurality of regularly distributed orifices; in that it further comprises, in line with the region of approximation of said cylinders, upstream of these, a vibrating feed conveyor; and in that it finally comprises, downstream of said cylinders, two horizontal scraper blades, one for each of the cylinders, the cutting edges of which come into contact with the ferrules of said cylinders, as close as possible to their approximation region.
Selon une caractéristique additionnelle du dispositif selon l'invention, un flanc de chacun des cylindres est ouvert, et ils comportent intérieurement des moyens permettant d'évacuer la matière arrachée par extrusion. According to an additional characteristic of the device according to the invention, a sidewall of each of the cylinders is open, and they internally comprise means making it possible to evacuate the material torn off by extrusion.
Les moyens d'évacuation de la matière extrudée sont soit des racleurs hélicoïdaux, soit des parois de forme ellipsoidale, inclinées, montées en libre rotation autour de l'axe du cylindre et lestées à une extrémité du côté ouvert dudit cylindre. The means for discharging the extruded material are either helical scrapers or walls of ellipsoidal shape, inclined, mounted in free rotation around the axis of the cylinder and ballasted at one end of the open side of said cylinder.
Selon une caractéristique additionnelle du dispositif selon ;'invention, les orifices d'une virole occupent sensiblement la moitié de la surface de celle-ci. According to an additional characteristic of the device according to the invention, the orifices of a ferrule occupy substantially half of the surface of the latter.
L'un des cylindres du dispositif selon l'invention, de préférence le cylindre inférieur, est fixe, solidaire d'un châssis, et entrainé en rotation par un moteur, tandis que l'autre cylindre est en rotation libre et peut être éloigné du premier ou rapproché, jusqu'à venir à son contact, selon la nature du produit à traiter. One of the cylinders of the device according to the invention, preferably the lower cylinder, is fixed, secured to a chassis, and driven in rotation by a motor, while the other cylinder is in free rotation and can be moved away from the first or closer, until coming into contact, depending on the nature of the product to be treated.
Le produit à traiter est amené, par 1 intermédiaire du convoyeur vibrant, jusqu'aux abords des rouleaux qui l entrainent, le matériau fluable pénétrant dans les orifices de la virole, puis en sortie des cylindres les lames racleuses séparent ledit matériau de celui qui n'a pas flué, le matériau extrudé tombant alors dans les cylindres et étant évacué vers l'extérieur. The product to be treated is brought, by means of the vibrating conveyor, to the surroundings of the rollers which drive it, the flowable material penetrating into the orifices of the shell, then at the outlet of the cylinders the scraper blades separate said material from that which n has not crept, the extruded material then falling into the cylinders and being discharged to the outside.
Il est à noter que le dispositif peut comporter des moyens connus permettant d'utiliser la chaleur et/ou un flux d'eau afin d'améliorer le processus de séparation. It should be noted that the device may include known means making it possible to use heat and / or a flow of water in order to improve the separation process.
Les avantages et les caractéristiques de la présente invention ressortiront plus clairement de la description qui suit et qui se rapporte au dessin annexé, lequel en représente un mode de réalisation non limitatif. The advantages and characteristics of the present invention will emerge more clearly from the description which follows and which refers to the appended drawing, which represents a non-limiting embodiment thereof.
Dans le dessin annexé
- la figure 1 représente une vue schématique de profil d'un dispositif selon l'invention.In the attached drawing
- Figure 1 shows a schematic profile view of a device according to the invention.
- la figure 2 représente une vue schématique partielle de face et en coupe du même dispositif. - Figure 2 shows a partial schematic front view and in section of the same device.
Si on se réfère à ces figures on peut voir qu'un dispositif de séparation selon l'invention comporte, solidarisés à un châssis 1, deux cylindres 2 et 3 superposés, d'axes , respectivement 20 et 30, parallèles et horizontaux, tournant dans des paliers, respectivement 21 et 31, le cylindre inférieur 2 étant mené en rotation dans le sens de la flèche R par un moteur 4, non représenté sur la figure 1. If we refer to these figures we can see that a separation device according to the invention comprises, secured to a frame 1, two cylinders 2 and 3 superimposed, with axes, respectively 20 and 30, parallel and horizontal, rotating in bearings, respectively 21 and 31, the lower cylinder 2 being rotated in the direction of arrow R by a motor 4, not shown in FIG. 1.
La partie du châssis 1 supportant les paliers 31 est constituée de deux bras parallèles 10 dont un seul est visible sur la figure 1, mobiles par rapport au reste du châssis 1, par pivotement par une de leurs extrémités autour d'un axe horizontal il parallèle aux axes 20 et 30, sous l'effet d'au moins un vérin 12 s'appliquant à leur autre extrémité, ledit pivotement ayant pour effet de modifier l'écartement des deux cylindres 2 et 3. The part of the chassis 1 supporting the bearings 31 consists of two parallel arms 10, only one of which is visible in FIG. 1, movable relative to the rest of the chassis 1, by pivoting by one of their ends about a horizontal axis it parallel to axes 20 and 30, under the effect of at least one jack 12 applying at their other end, said pivoting having the effect of modifying the spacing of the two cylinders 2 and 3.
Le réglage de l'écartement des cylindres 2 et 3 est réalisé au moyen d'une butée 13, réglable en hauteur, solidaire du châssis 1 du côté du vérin 12, et contre laquelle prennent appui les bras 10. The spacing of the cylinders 2 and 3 is adjusted by means of a stop 13, adjustable in height, integral with the chassis 1 on the side of the jack 12, and against which the arms 10 bear.
Chacun des cylindres 2 et 3 est essentiellement constitué d'une armature robuste, respectivement 22 et 32, largement évidée, recouverte extérieurement d'une virole fine, respectivement 23 et 33, perforée d'une pluralité d'orifices, respectivement 24 et 34, régulièrement répartis et occupant sensiblement la moitié de la surface des viroles 23 et 33. Each of the cylinders 2 and 3 essentially consists of a robust armature, respectively 22 and 32, largely hollowed out, covered on the outside with a fine ferrule, respectively 23 and 33, perforated with a plurality of orifices, respectively 24 and 34, regularly distributed and occupying substantially half the surface of the ferrules 23 and 33.
Le produit à traiter est amené au plus près et en amont des cylindres 2 et 3, dans la région 5 où ceux-ci sont le plus proches, au moyen d'un convoyeur vibrant 50. The product to be treated is brought as close and upstream of the cylinders 2 and 3, to the region 5 where these are closest, by means of a vibrating conveyor 50.
Chacun des cylindres 2 et 3 comporte en aval une lame racleuse horizontale, respectivement 25 et 35, non représentées sur la figure 2, dont le bord coupant, respectivement 26 et 36, affleure sensiblement tangentiellement la virole, respectivement 23 et 33. Each of the cylinders 2 and 3 comprises downstream a horizontal scraper blade, respectively 25 and 35, not shown in FIG. 2, the cutting edge of which, respectively 26 and 36, is substantially tangentially flush with the ferrule, respectively 23 and 33.
La lame racleuse 35 du cylindre 3 est montée fixement sur un support 37 solidaire des bras 10, tandis que la lame racleuse 25 du cylindre 2 est solidaire d'un support 27 monté pivotant, avec possibilité de blocage, autour de l'axe 20, permettant le retrait de la lame 25 en cas de bourrage en sortie des cylindres 2 et 3. The scraper blade 35 of the cylinder 3 is fixedly mounted on a support 37 secured to the arms 10, while the scraper blade 25 of the cylinder 2 is secured to a support 27 pivotally mounted, with the possibility of locking, around the axis 20, allowing the blade 25 to be removed in the event of jamming at the outlet of cylinders 2 and 3.
I1 y a lieu de remarquer d'une part que les bords 26 et 36 ne sont pas dans un même plan vertical, le bord 26 étant engagé plus profondément dans la région 5, et d'autre part que la lame 25 pourrait aussi bien être solidarisée à un support du même type que le support 27. It should be noted on the one hand that the edges 26 and 36 are not in the same vertical plane, the edge 26 being engaged more deeply in the region 5, and on the other hand that the blade 25 could as well be secured to a support of the same type as support 27.
Le fonctionnement du dispositif selon l'invention est le suivant
- le produit à traiter, par exemple des pneumatiques usés ou des morceaux de pneumatiques, est amené dans la région 5 par ie convoyeur vibrant 50, et du fait de la rotation du cylindre 2 elle est entraînée et pressée entre les deux cylindres 2 et 3, ce qui a pour effet la contre-rotation, dans le sens R', du cylindre 3 par friction et inertie;;
- sous effet de la pression le caoutchouc flue et est extrudé à travers les orifices 24 et 34, et du fait que ces orifices 24 et 34 occupent sensiblement la moitié de la surface des viroles 23 et 33, la remontée du caoutchouc dans ces orifices est approximativement de deux fois son épaisseur moyenne, d'où une bonne pénétration et un commencement d'arrachement du caoutchouc de son substrat, la faible épaisseur des viroles 23 et 33 permettant de plus une expansion du produit après franchissement des orifices, ce qui facilite son arrachement
- en aval des cylindres 2 et 3 les lames 25 et 35 achèvent la séparation du caoutchouc en raclant la surface des viroles 23 et 33, avant que celui-ci ne ressorte des orifices 24 et 34,
- enfin le substrat débarrassé du caoutchouc, c'est-à-dire la nappe textile ou métallique, est éjecté en aval des lames 25 et 35.The operation of the device according to the invention is as follows
- The product to be treated, for example used tires or pieces of tires, is brought into region 5 by the vibrating conveyor 50, and due to the rotation of cylinder 2 it is driven and pressed between the two cylinders 2 and 3 , which has the effect of counter-rotation, in the direction R ', of the cylinder 3 by friction and inertia;
- under the effect of the pressure the rubber flows and is extruded through the orifices 24 and 34, and the fact that these orifices 24 and 34 occupy substantially half of the surface of the ferrules 23 and 33, the rise of the rubber in these orifices is approximately twice its average thickness, hence good penetration and the start of tearing of the rubber from its substrate, the small thickness of the ferrules 23 and 33 also allowing product expansion after crossing the orifices, which facilitates its wrenching
- downstream of the cylinders 2 and 3, the blades 25 and 35 complete the separation of the rubber by scraping the surface of the ferrules 23 and 33, before the latter emerges from the orifices 24 and 34,
finally, the substrate freed from rubber, that is to say the textile or metallic sheet, is ejected downstream of the blades 25 and 35.
Le caoutchouc après son extrusion tombe à l'intérieur des cylindres 2 et 3, sur des parois inclinées, respectivement 6 et 7, comme cela est visible sur la figure 2. The rubber after its extrusion falls inside the cylinders 2 and 3, on inclined walls, respectively 6 and 7, as can be seen in FIG. 2.
La paroi 6 est de forme ovale, elle est inclinée diagonalement dans le cylindre 3 et traversée centralement par l axe 30 sur lequel elle est montée en libre rotation par l'intermédiaire d'un palier 60, et son bord 61 racle la paroi interne de l'armature 32. Un flanc 38 du cylindre 3, ouvert et garni d'un rebord périphérique 39, permet l'évacuation du caoutchouc dans un récipient ou un convoyeur extérieur 62, tandis que la partie 63 de la paroi 6 du côté du flanc 38 est lestée de manière que la paroi 6 reste inclinée par gravité pendant la rotation du cylindre 3. The wall 6 is oval in shape, it is inclined diagonally in the cylinder 3 and crossed centrally by the axis 30 on which it is mounted in free rotation by means of a bearing 60, and its edge 61 scrapes the internal wall of the frame 32. A side 38 of the cylinder 3, open and furnished with a peripheral rim 39, allows the evacuation of the rubber in a container or an external conveyor 62, while the part 63 of the wall 6 on the side of the side 38 is ballasted so that the wall 6 remains inclined by gravity during the rotation of the cylinder 3.
De la meme manière, le cylindre 2 comporte un flanc ouvert 28 garni d'un rebord 29 débouchant au-dessus d'un récipient ou convoyeur extérieur 72, et la paroi 7 est de forme semi-ovale, inclinée dans la demi-partie inférieure du cylindre 2, sous i'axe 20, en libre rotation sur l'axe 20 par l intermédiaire d'un palier 70, son bord 71 raclant la paroi interne de i armature 22, et sa partie 73 du côté du flanc ouvert 28 étant lestée. Likewise, the cylinder 2 has an open flank 28 provided with a flange 29 opening out above an external container or conveyor 72, and the wall 7 is of semi-oval shape, inclined in the lower half-part. of the cylinder 2, under the axis 20, in free rotation on the axis 20 by means of a bearing 70, its edge 71 scraping the internal wall of the frame 22, and its part 73 on the side of the open flank 28 being weighted.
Les avantages procurés par le dispositif objet de la présente invention, notamment vis-à-vis de celui du document EP 0.018.664, sont les suivants
- possibilité d'adapter l'écartement entre les cylindres en fonction de la nature de la matière à traiter, par exemple dans le cas de pneumatiques de poids-lourds, cet écartement tenant compte de l'épaisseur des tringles de ceux-ci
- un seul cylindre moteur, ce qui réduit les coûts de fabrication, sachant qu'un tel dispositif nécessite une grande puissance.The advantages provided by the device which is the subject of the present invention, in particular with respect to that of document EP 0.018.664, are the following:
- possibility of adapting the spacing between the cylinders as a function of the nature of the material to be treated, for example in the case of truck tires, this spacing taking into account the thickness of the rods thereof
- A single engine cylinder, which reduces manufacturing costs, knowing that such a device requires great power.
- les matériaux sont parfaitement séparés, la nappe textile ou métallique ne flue pas à travers les orifices des viroles. du fait que les cylindres ne sont pas en contact et que c'est le matériau le plus tendre qui flue en priori, ce qui permet de plus la récupération du matériau qui n'a pas flué. - the materials are perfectly separated, the textile or metallic sheet does not flow through the orifices of the ferrules. owing to the fact that the cylinders are not in contact and that it is the softest material which creeps a priori, which allows moreover the recovery of the material which did not creep.
- possibilité en cas d'usure ou de casse de remplacer uniquement les viroles. - possibility in case of wear or breakage to replace only the ferrules.
Il va de soi que la présente invention ne saurait être limitée à la description qui précède d'un de ses modes de réalisation, susceptible de subir un certain nombre de modifications sans pour autant sortir du cadre de l'invention. En particulier, si la description ci-dessus porte sur le traitement des pneumatiques usés, le dispositif selon l invention peut également être appliqué au traitement de nombreux autres déchets industriels. It goes without saying that the present invention cannot be limited to the preceding description of one of its embodiments, capable of undergoing a certain number of modifications without departing from the scope of the invention. In particular, if the above description relates to the treatment of used tires, the device according to the invention can also be applied to the treatment of many other industrial wastes.
