Abstract

Continuous conveyor device for a steep slope, which may even be vertical, for a bulk product and having a self-cleaning function. The elevator device is composed: of two belts 1 and 2 which, in the ascending part, collaborate in order to form a leaktight tube produced by bringing into contact flexible magnetic strips, each secured to each of the edges of the belts 1 and 2 at the level of the pulleys 3 and 8; of hauling cables 16 and 15, equipped transversely with spring leaves, which form the tube thus formed, here and there, into cells in order to prevent the product from sliding downwards. The rollers 11 guide the cables so that the latter serve as supports for the spring leaves so that they exert a permanent force over the entire length of the rising part. The belt is thus continuously cleaned on the return pulleys.

Description

On sait c'il existe différents type de systêmes destin sà élever Eu produit en vrac dans de forte pentes ou bien, à la verticale.We know that there are different types of systems intended to raise Eu produced in bulk in steep slopes or, vertically.

On connait tout d'abord l' élévateur à vis d'archirède logée dans un tube, cui élève le produit suivant la direction de 1' axe de la vis quand celle-ci est en rotation.First of all, we know the Archiredes screw elevator housed in a tube, which elevates the product along the direction of the axis of the screw when the latter is rotating.

On connait, par ailleurs, l'ancenseur à godets multiples fonctionant en circuit fermé et dont la partie basse descend sous le niveau de la cuve contenant le matériau en vrac.We also know the multiple bucket elevator operating in a closed circuit and the lower part of which drops below the level of the tank containing the bulk material.

Enfin il existe différents dispositifs utilisant une bande souple continue se refermant et munie dans leur partie périphérique et extérieure, de bras destinés à exercer une force de loin en loin de telle sorte que la bande comporte durant l'ascensior., une multitude d'alvéoles empêchant ainsi le produit ae glisser vers le bas. Finally, there are different devices using a continuous flexible band closing and provided in their peripheral and external part, with arms intended to exert a force from time to time so that the band comprises, during the ascent., A multitude of cells preventing the product from sliding down.

l'inconvénient mateur des deux premiers dispositifs, réside dans le frit qu'ils sont très vite encrassés. T'expérience montre que ce type d'appareil doit être souvent démonté pour procéder au nettoyage des pièces en contact avec le produit. the dull drawback of the first two devices lies in the friedness that they are very quickly fouled. Experience has shown that this type of device must often be dismantled in order to clean the parts in contact with the product.

Le rlus, leur fonctionement induit des frottements important entre les structures et le produit aboutissant à de mauvais rendements mécaniques et accélérant l'usure.The rlus, their operation induces significant friction between the structures and the product resulting in poor mechanical performance and accelerating wear.

les dispositifs connus en bande continue ont les inconvénients suivant: - or certains il y a utilisation de bande à bord.known devices in continuous strip have the following drawbacks: - or some there is use of strip on board.

- Etanchéité aléatoire dans la partie de l'ascension.- Random sealing in the part of the ascent.

- Compte tenu que le chargement s'opère à l'horizontal, il y a écrasement du tube formé par la bande, au niveau du change, ment de pente de part et d'autre du tronçon ascendant.- Given that the loading takes place horizontally, the tube formed by the strip is crushed, at the level of the change, the slope on either side of the ascending section.

le dispositif relatif à l'invention, met en oeuvre deux bandes 1, 2 de fabricetion classique d'origine, dont leur superposition en amont de la partie à forte pente, réalise un tube étanche dont la section est aplatie pour faciliter le passage aux poulies 3, 4 de déviation en élévation.

Figure img00010001
the device relating to the invention, implements two bands 1, 2 of original conventional fabricetion, whose superposition upstream of the steep part, produces a sealed tube whose section is flattened to facilitate passage to the pulleys 3, 4 deviation in elevation.
Figure img00010001

La figure 1 montre l'ensemble cu dispositif composé de deux circuits; le circuit de la bande de recouvrement 1 , composé de poulies, - > pour la poulie Ce tension, 3 pour la poulie de déviation dite en compression, 6 pour la poulie oe retour.Figure 1 shows the whole device cu composed of two circuits; the circuit of the cover strip 1, composed of pulleys, -> for the pulley This tension, 3 for the deflection pulley called in compression, 6 for the return pulley.

le second circuit, dit circuit principal, est composé d'une poulie de tension A2 , d'une poulie de déviation 4 , d'une poulie de retour 9 , d'une poulie de déviation 10 en support pour le brin retour, d'une poulie de déviation b en compression.the second circuit, called the main circuit, is composed of a tension pulley A2, a deflection pulley 4, a return pulley 9, a deflection pulley 10 in support for the return strand, a deflection pulley b in compression.

Pn pointillés sur la figure 1, sont représentés les cables tracteurs 15,16 ocllaborant aveciles poulies-guides 11. Pn dotted in FIG. 1, the towing cables 15,16 ocllaborant with pulleys-guides 11 are shown.

Sur la même figure, on peut voir enfin les vérins de tension 7, 13 et le bc de chargement 14.In the same figure, we can finally see the tension cylinders 7, 13 and the loading bc 14.

la figure 2 montre une coupe de l'ensemble des deux bandes 1 et 2 dans le tronçon en pente forte de l'élévateur, les galets Il les cables tracteurs 15 a, 5 b, 15 a, 16b, les lames de ressort 17 a, 17 b, les attaches 18 fixant les lames 17 sur les cables.Figure 2 shows a section of the assembly of the two bands 1 and 2 in the steep section of the elevator, the rollers II the tractor cables 15a, 5b, 15a, 16b, the spring blades 17a , 17 b, the fasteners 18 fixing the blades 17 on the cables.

La figure 3 montre une vue en élévation de l'ensemble élévateur comprenant les bandes réunies 1, 2 , les cables tracteurs 15 a, 15 b, les lames-ressort 17 a, les attaches 18, les galets 11.FIG. 3 shows an elevation view of the lifting assembly comprising the joined bands 1, 2, the towing cables 15 a, 15 b, the leaf springs 17 a, the fasteners 18, the rollers 11.

n figure 5, montre une coupe de l'ensemble poulie de déviation 3 o l'on peut voir que les poulies 3 b, 3 c sont déssolidarisées de la poulie 3 a elle méme réservée à l'ensemble bandes 1, 2 , pour permettre une même vitesse tangentielle entre les cables et les bandes. n Figure 5, shows a section of the deflection pulley assembly 3 where it can be seen that the pulleys 3b, 3c are separated from the pulley 3a which is itself reserved for the strip assembly 1, 2, to allow same tangential speed between cables and bands.

On peut voir que les deux bandes sont réunies par leurs bords latéraux à l'aide d'aimants souples 19 a, 19 b ; La bande souple aimantée 19 a est collée sur le bord de la bande 1 , la bande souple aimantée 19 b est collée sur le bord de la bande 2. It can be seen that the two strips are joined by their lateral edges using flexible magnets 19 a, 19 b; The magnetized flexible strip 19 a is bonded to the edge of the strip 1, the magnetized flexible strip 19 b is bonded to the edge of the strip 2.

On peut voir aussi le produit transporté 20 oui est comprimé à l'intérieur du tube 21 formé par l'ensemble des deux bandes 1 et 2 et dont la section est en forme de lentille.We can also see the transported product 20 yes is compressed inside the tube 21 formed by the assembly of the two bands 1 and 2 and whose section is in the form of a lens.

la lame de ressort ?'/ située dans la tangente de la poulie 3 a, peut éventuellement se déformer suivant la courbe de la poulie 3 a . Pour cela, l'attache, qui est solidaire du cable, possède un jeu mécanique permettant à la lame de coulisser latéralement la différence de longueur induite par le changement de courbure.the leaf spring? '/ located in the tangent of the pulley 3 a, can possibly deform along the curve of the pulley 3 a. For this, the fastener, which is integral with the cable, has a mechanical play allowing the blade to slide laterally the difference in length induced by the change in curvature.

Une butée à chaque bout 22 a, 22 b, évite la sortie complète de la lame les poulies 3 b, 3 c sont solidaires en rotation entre elles la poulie 3 a entant folle sur l'arbre de liaison des deux poulies de cibles.A stopper at each end 22 a, 22 b, prevents the blade from coming out completely. The pulleys 3 b, 3 c are integral in rotation with each other the pulley 3 a going mad on the connecting shaft of the two target pulleys.

Ainsi, les poulies notrices sont celles entrainant les cables.Thus, the noting pulleys are those driving the cables.

Il est possible, comme sur la figure 1 , de relier les poulies à cables de l'ensemble poulies 3 à l'ensemble poulies 8 par une chaine 23.It is possible, as in FIG. 1, to connect the cable pulleys of the pulley assembly 3 to the pulley assembly 8 by a chain 23.

toutes les poulies sur lesquelles s'enroulent les bande, 2 ont une géométrie incurvée sur le modèle de la poulie 3 a.all the pulleys on which the strips are wound, 2 have a curved geometry on the model of the pulley 3 a.

Cette configuration permet aux bandes d'avoir une géométrie en auge dégageant ainsi une section pour contenir le produit à transporter.This configuration allows the bands to have a trough geometry thus freeing a section to contain the product to be transported.

les bandes i, 2 sont en matériau souple tel que le caoutchouc et sont montées en légère extension de telle sorte que dans les déviations 1G bande oui suit une trajectoire suivant le plus petit raison ne subisse jamais ae compression, compression oui souvent génère des plis préjudiciables à la bomne tenue du matériau constitutif dans le temps.the bands i, 2 are made of flexible material such as rubber and are mounted in slight extension so that in the deviations 1G band yes follows a trajectory following the smallest reason never undergoes compression, compression yes often generates harmful folds in the fall, holding of the constituent material over time.

B- figure K montre le détail en élévation en vue latérale de l'ensemble poulies 3. B- Figure K shows the detail in elevation in side view of the pulley assembly 3.

On peut --oir les poches 24 a, b, c, d, e, induites par le pro duit transporta, entre deux groupe ae lames 17. We can see the pockets 24 a, b, c, d, e, induced by the product transported, between two groups of blades 17.

les galets 1 servent maintenir constant l'écart entre les cables supérieurs et inférieurs de telle sorte que les lames exercent une contrainte potentiellement constante.the rollers 1 serve to keep the gap between the upper and lower cables constant so that the blades exert a potentially constant stress.

le choix des lames souples est important car, selon les produits transportés, il y a rIsque de présence de quelques éléments durs et à grosse granulométrie aui se coinceraient entre ces lames rigides.the choice of flexible blades is important because, depending on the products transported, there is the risk of the presence of a few hard elements with large particle sizes that would get caught between these rigid blades.

ku contraire, les lames souples s'adaptent aux différentes géométries de la section du tube 21 en fonction de la nature des produits transportés le fonctionnement du dispositif relatif à l'invention est le suivant:
Le produit est pris en charge par la bande 2 au niveau du bac verseur 14. Plus loin, au niveau de la tangente de la poulie 5 , la bande de recouvrement 1 vient se plaquer par ses bords latéraux sur les bords latéraux de la bande 2
Ainsi les aimants souples, respectivement 19 a, 19 b et 19 c, 19 d, se mettent en contact pour solidariser les bandes 1 e 2 formant ainsi le tube 21.on the contrary, the flexible blades adapt to the different geometries of the section of the tube 21 depending on the nature of the products transported the operation of the device relating to the invention is as follows:
The product is supported by the strip 2 at the pouring pan 14. Further, at the tangent of the pulley 5, the covering strip 1 is pressed by its lateral edges on the lateral edges of the strip 2
Thus the flexible magnets, respectively 19 a, 19 b and 19 c, 19 d, come into contact to secure the strips 1 e 2 thus forming the tube 21.

Plus loin, les cables 'lb G et b positionnent successivement les lames oui lui sont solidaires, au point de tangente de telle sorte oue, avec le concours des lames opposées , cela forme une succession d'alvéoles empêchant ainsi au produit de glisser vers le bas.Farther on, the cables' lb G and b successively position the blades yes, they are integral with it, at the point of tangent so that, with the help of the opposite blades, this forms a succession of cells thus preventing the product from sliding towards the low.

Come la fonction tractrice est assure par les cables, le tube 21 ne subit aucune variation de tension induite par la dénivellation.As the towing function is provided by the cables, the tube 21 does not undergo any voltage variation induced by the drop.

je ce -fait le dimensionement de la section des bandes n'est pas tributaire de la dFnivellation.  I do the sizing of the strip section is not dependent on the unevenness.

n partie haute du dispositif, le produit est dérié selon une trajectoire horizontale après la séparation des deux banches 1 et 2 au point de tangente des poulies 4 et 6 I1 est à noter que les parties horizontales du bas et du haut peuvent être prolongées à la demande, ce qui souvent évite une reprise ces charges.  n upper part of the device, the product is deviated along a horizontal trajectory after the separation of the two forms 1 and 2 at the point of tangent of the pulleys 4 and 6 I1 it should be noted that the horizontal parts of the bottom and of the top can be extended to the asks, which often avoids a resumption of these charges.
