Description

La prĆ©sente invention concerne un fondoir pour homogĆ©nĆ©iser et chauffer un produit, notamment une composition de marquage au sol, utilisable Ć  l'Ć©tat liquide ou pĆ¢teux, fondoir comprenant une cuve verticale destinĆ©e Ć  recevoir le produit, cette cuve comportant une paroi latĆ©rale cylindrique solidaire d'un fond et Ć©tant pourvue d'un dispositif de chauffage ainsi que d'un dispositif d'agitation.The present invention relates to a melter for homogenizing and heating a product, in particular a ground marking composition that can be used in the liquid or pasty state, the melter comprising a vertical vessel intended to receive the product, this vessel having a cylindrical side wall integral with a bottom and being provided with a heating device and a stirring device.

Des fondoirs de ce type sont actuellement utilisĆ©s pour prĆ©parer les compositions de marquage au sol servant Ć  dĆ©limiter des voies de circulation routiĆØre.Melters of this type are currently used to prepare ground marking compositions for delimiting road traffic lanes.

Ces fondoirs ne donnent toutefois par pleinement satisfaction Ć  leurs utilisateurs. La principale raison est en effet qu'ils doivent ĆŖtre maintenus en fonctionnement pendant de longues pĆ©riodes de temps pour rĆ©aliser une homogĆ©nĆ©isation convenable des produits, ce qui ne permet pas d'utiliser les machines de marquage au maximum de leurs possibilitĆ©s.These melters do however give full satisfaction to their users. The main reason is that they must be kept in operation for long periods of time to achieve a proper homogenization of the products, which does not allow the use of marking machines to their full potential.

La prĆ©sente invention se propose de remĆ©dier Ć  cet inconvĆ©nient et, pour ce faire, elle a pour objet un fondoir ayant la structure indiquĆ©e au premier paragraphe ci-dessus et qui est caractĆ©risĆ© en ce que le dispositif d'agitation comprend un arbre central s'Ć©tendant dans la cuve, coaxialement avec la paroi latĆ©rale de celle-ci, un organe moteur pour entraĆ®ner l'arbre central en rotation, et deux disques perforĆ©s portĆ©s par l'arbre central, parallĆØlement au fond de la cuve, le disque infĆ©rieur Ć©tant adjacent audit fond et sĆ©parĆ© de ce dernier par une distance plus petite que celle le sĆ©parant du disque supĆ©rieur.The present invention proposes to remedy this drawback and, for this purpose, it relates to a melter having the structure indicated in the first paragraph above and which is characterized in that the stirring device comprises a central shaft s' extending in the tank coaxially with the side wall thereof, a driving member for driving the central shaft in rotation, and two perforated discs carried by the central shaft, parallel to the bottom of the tank, the lower disk being adjacent bottom and separated from the latter by a distance smaller than that separating it from the upper disk.

GrĆ¢ce Ć  ce dispositif d'agitation, le produit Ć  prĆ©parer peut ĆŖtre soumis Ć  un brassage Ć©nergique permettant de l'homogĆ©nĆ©iser plus rapidement qu'avec les dispositifs d'agitation des fondoirs actuels.With this stirring device, the product to be prepared can be subjected to vigorous stirring to homogenize more quickly than with the stirring devices of the current melters.

Les machines servant Ć  appliquer le produit Ć  sa sortie du fondoir selon l'invention peuvent donc ĆŖtre utilisĆ©es dans de meilleurs conditions, ce qui permet d'augmenter leur rendement.The machines used to apply the product to its output of the melter according to the invention can be used in better conditions, which increases their efficiency.

De prĆ©fĆ©rence, les disques comportent le mĆŖme nombre de trous, leurs trous respectifs Ć©tant Ć©quidistants Ć  la fois angulairement et radialement.Preferably, the discs comprise the same number of holes, their respective holes being equidistant both angularly and radially.

Les trous rƩalisƩs dans les disques permettent Ơ une partie du produit de circuler dans un sens Ơ proximitƩ de l'arbre central et dans le sens opposƩ Ơ proximitƩ de la face latƩrale de la cuve, ce qui permet un brassage Ʃnergique du produit.The holes in the discs allow a portion of the product to flow in a direction near the central shaft and in the opposite direction near the side face of the tank, allowing a vigorous mixing of the product.

Pour que le dispositif d'agitation fonctionne de maniĆØre rĆ©guliĆØre, il est souhaitable que les trous de l'un des disques soient respectivement Ć©quidistants angulairement des trous de l'autre disque.In order for the stirring device to operate smoothly, it is desirable for the holes in one of the discs to be respectively angularly equidistant from the holes in the other disc.

Selon un mode de rĆ©alisation prĆ©fĆ©rĆ© de l'invention, le fond de la cuve est reliĆ© Ć  la paroi latĆ©rale de celle-ci par une partie tronconique s'Ć©vasant vers le haut, le disque infĆ©rieur Ć©tant situĆ© au niveau de la partie tronconique et ayant un diamĆØtre infĆ©rieur au diamĆØtre du disque supĆ©rieur.According to a preferred embodiment of the invention, the bottom of the tank is connected to the side wall thereof by a frustoconical part flaring upwards, the lower disk being located at the frustoconical portion and having a diameter smaller than the diameter of the upper disk.

Pour amƩliorer les performances du dispositif d'agitation, l'arbre central peut avantageusement porter deux pales radiales diamƩtralement opposƩes, ces pales Ʃtant inclinƩes en sens inverse et situƩes au-dessus du disque supƩrieur.To improve the performance of the stirring device, the central shaft may advantageously carry two diametrically opposed radial blades, these blades being inclined in opposite directions and located above the upper disk.

Par ailleurs, l'organe moteur est de prƩfƩrence fixƩ Ơ l'extrƩmitƩ supƩrieure de l'arbre central et peut entraƮner ce dernier en rotation dans un sens ou dans l'autre.Furthermore, the drive member is preferably attached to the upper end of the central shaft and can drive the latter in rotation in one direction or the other.

Selon une caractĆ©ristique particuliĆØre du fondoir selon l'invention, le dispositif de chauffage comprend une chambre de combustion situĆ©e sous le fond et autour de la partie infĆ©rieure de la paroi latĆ©rale de la cuve, un brĆ»leur reliĆ© Ć  la chambre de combustion, une source d'Ć©nergie pour alimenter le brĆ»leur et un dispositif d'Ć©vacuation des fumĆ©es.According to a particular characteristic of the melter according to the invention, the heating device comprises a combustion chamber located under the bottom and around the lower part of the side wall of the tank, a burner connected to the combustion chamber, a source of combustion. energy to supply the burner and a smoke evacuation device.

Le produit contenu dans la cuve peut ainsi ĆŖtre portĆ© rapidement Ć  l'Ć©tat souhaitĆ© pour son utilisation ultĆ©rieure.The product contained in the tank can thus be brought quickly to the desired state for later use.

De prƩfƩrence, le dispositif d'Ʃvacuation des fumƩes comprend un espace annulaire reliƩ Ơ la chambre de combustion, cet espace entourant extƩrieurement la paroi latƩrale de la cuve et comportant au moins une sortie situƩe au niveau de l'extrƩmitƩ supƩrieure de la cuve.Preferably, the flue gas discharge device comprises an annular space connected to the combustion chamber, this space surrounding the outside wall of the tank and having at least one outlet located at the upper end of the tank.

La tempĆ©rature du produit contenu dans la cuve peut ainsi ĆŖtre uniforme, quel que soit l'emplacement dans celle-ci.The temperature of the product contained in the tank can thus be uniform, regardless of the location therein.

Pour uniformiser parfaitement la tempƩrature du produit, il est souhaitable que l'espace annulaire renferme des parois verticales dƩfinissant des chicanes.To perfectly equalize the temperature of the product, it is desirable that the annular space contains vertical walls defining baffles.

Par ailleurs, l'espace annulaire peut avantageusement ĆŖtre dĆ©limitĆ© extĆ©rieurement par une paroi cylindrique revĆŖtue extĆ©rieurement d'un matĆ©riau isolant situĆ© dans une enveloppe de protection.Furthermore, the annular space may advantageously be delimited externally by a cylindrical wall externally coated with an insulating material located in a protective envelope.

Les dĆ©perditions de chaleur peuvent en effet ainsi ĆŖtre limitĆ©es au maximum, ce qui permet de rĆ©duire les dĆ©penses de chauffage.Heat losses can indeed be limited to the maximum, which reduces heating costs.

Un mode d'exĆ©cution de la prĆ©sente invention sera dĆ©crit ci-aprĆØs Ć  titre d'exemple nullement limitatif en rĆ©fĆ©rence aux dessins annexĆ©s dans lesquels :

  • la figure 1 est une vue en coupe schĆ©matique d'un fondoir conforme Ć  l'invention ;
  • la figure 2 est une vue en coupe selon la ligne II-II de la figure 1 ;
  • la figure 3 est une vue en coupe schĆ©matique de la cuve du fondoir reprĆ©sentĆ© sur les figures 1 et 2 ; et
  • la figure 4 est une vue en coupe selon la ligne IV-IV de la figure 3.

Le fondoir que l'on peut voir sur les dessins a Ć©tĆ© mis au point pour homogĆ©nĆ©iser et porter Ć  l'Ć©tat liquide les compositions de marquage qui sont destinĆ©es Ć  ĆŖtre appliquĆ©es sur les routes, autoroutes, etc. afin de dĆ©limiter des voies de circulation.The melter that can be seen in the drawings was developed to homogenize and bring to liquid form the marking compositions that are intended to be applied on roads, highways, etc. to delimit traffic lanes.

Il va de soi cependant que l'on ne sortirait pas du cadre de la prĆ©sente invention si ce fondoir Ć©tait utilisĆ© pour prĆ©parer d'autres produits, thermoplastiques ou non, devant ĆŖtre homogĆ©nĆ©isĆ©s et se trouver Ć  l'Ć©tat liquide ou pĆ¢teux pour pouvoir ĆŖtre exploitĆ©s.It goes without saying, however, that it would not be outside the scope of the present invention if this melter were used to prepare other products, thermoplastic or not, to be homogenized and to be in the liquid or pasty state to be exploited.

Le fondoir reprĆ©sentĆ© sur les dessins comprend une cuve verticale 1 contenant un produit 2 destinĆ© Ć  ĆŖtre homogĆ©nĆ©isĆ© et amenĆ© par chauffage Ć  l'Ć©tat liquide ou pĆ¢teux de faƧon Ć  pouvoir ĆŖtre utilisĆ©.The melter shown in the drawings comprises a vertical vessel 1 containing a product 2 intended to be homogenized and brought by heating in the liquid or pasty state so as to be used.

Le dispositif d'agitation 8 comprend un arbre central 9 s'Ć©tendant dans la cuve, coaxialement avec la paroi latĆ©rale 3 de celle-ci, et deux disques perforĆ©s 10, 11 montĆ©s sur l'arbre central, parallĆØlement au fond 4.The stirring device 8 comprises a central shaft 9 extending in the tank, coaxially with the side wall 3 thereof, and two perforated discs 10, 11 mounted on the central shaft, parallel to the bottom 4.

Le disque infƩrieur 10 est situƩ au niveau de la partie tronconique 5 de la cuve et dƩlimite un espace Ʃtroit avec le fond 4. Il comporte quatre trous identiques 12 Ʃquidistants Ơ la fois angulairement et radialement.The lower disk 10 is located at the frustoconical portion 5 of the tank and delimits a narrow space with the bottom 4. It has four identical holes 12 equidistant both angularly and radially.

Le disque supĆ©rieur 11 est plus grand que le disque infĆ©rieur 10 qui est plus Ć©loignĆ© de lui que du fond 4. Il comporte Ć  son tour quatre trous identiques 13 Ć©quidistants Ć  la fois angulairement et radialement, ses trous Ć©tant lĆ©gĆØrement plus grands que ceux du disque 10.The upper disk 11 is larger than the lower disk 10 which is farther from it than from the bottom 4. It has in turn four identical holes 13 equidistant both angularly and radially, its holes being slightly larger than those of the disk. 10.

En se rƩfƩrant en particulier aux figures 2 et 4, on remarquera que les disques 10, 11 sont montƩs sur l'arbre 9 de telle sorte que les trous de l'un soient dƩcalƩs angulairement par rapport aux trous de l'autre, les dƩcalages Ʃtant identiques.Referring in particular to FIGS. 2 and 4, it will be noted that the discs 10, 11 are mounted on the shaft 9 so that the holes of one are angularly offset relative to the holes of the other, the offsets being identical.

L'arbre 9 est reliĆ©, au niveau de son extrĆ©mitĆ© supĆ©rieure, Ć  un organe moteur 14 destinĆ© Ć  l'entraĆ®ner en rotation, cet organe Ć©tant un moteur Ć©lectrique dans le mode de rĆ©alisation reprĆ©sentĆ© ici, mais pouvant ĆŖtre d'un autre type.The shaft 9 is connected at its upper end to a motor member 14 for driving it in rotation, this member being an electric motor in the embodiment shown here, but can be of another type.

L'organe moteur 14 est fixĆ© d'une maniĆØre connue en soi sur un support prĆ©vu Ć  la partie supĆ©rieure de la cuve et est reliĆ© Ć  l'arbre 9 par des moyens conventionnels.The motor member 14 is fixed in a manner known per se on a support provided at the upper part of the tank and is connected to the shaft 9 by conventional means.

Il est commandƩ Ơ partir d'un boƮtier de commande 15 et apte Ơ entraƮner l'arbre 9 dans un sens ou dans l'autre.It is controlled from a control box 15 and adapted to drive the shaft 9 in one direction or the other.

Dans le mode de rƩalisation reprƩsentƩ, l'arbre 9 a une section carrƩe et porte deux pales radiales 16 diamƩtralement opposƩes. Ces pales sont situƩes au-dessus du disque supƩrieur 11 et, comme le montre la figure 4, elles sont inclinƩes en sens inverse et fixƩes contre deux faces opposƩes de l'arbre 9.In the embodiment shown, the shaft 9 has a square section and carries two radial blades 16 diametrically opposed. These blades are situated above the upper disk 11 and, as shown in FIG. 4, they are inclined in opposite directions and fixed against two opposite faces of the shaft 9.

La cuve est Ć©galement pourvue d'un dispositif de chauffage 17 permettant d'amener le produit 2 Ć  l'Ć©tat liquide ou pĆ¢teux.The tank is also provided with a heating device 17 for bringing the product 2 in the liquid or pasty state.

Le dispositif de chauffage 17, qui est visible sur les figures 1 et 2, comprend une chambre de combustion 18 situƩe sous le fond 4 et autour de la partie tronconique 5 de la cuve 1, un brƻleur 19 reliƩ Ơ la chambre 18 et alimentƩ avec un mƩlange appropriƩ de gaz et d'air, et un dispositif d'Ʃvacuation des fumƩes 20.The heating device 17, which can be seen in FIGS. 1 and 2, comprises a combustion chamber 18 situated under the bottom 4 and around the frustoconical portion 5 of the vessel 1, a burner 19 connected to the chamber 18 and fed with an appropriate mixture of gas and air, and a flue gas evacuation device 20.

Il va de soi que le brƻleur pourrait utiliser du fioul ou tout autre combustible conventionnel.It goes without saying that the burner could use fuel oil or any other conventional fuel.

Le dispositif d'Ć©vacuation des fumĆ©es 20 comprend un espace annulaire 21 reliĆ© Ć  la chambre de combustion 18. L'espace 21 entoure extĆ©rieurement la paroi latĆ©rale 3 de la cuve 1 et comporte deux sorties 22 mĆ©nagĆ©es dans la paroi supĆ©rieure 6 de ladite cuve, ces sorties Ć©tant diamĆ©tralement opposĆ©es et aptes Ć  ĆŖtre reliĆ©es Ć  un dispositif de traitement des fumĆ©es non reprĆ©sentĆ©.The smoke evacuation device 20 comprises an annular space 21 connected to the combustion chamber 18. The space 21 surrounds externally the side wall 3 of the tank 1 and has two outlets 22 formed in the upper wall 6 of said tank, these outlets being diametrically opposed and adapted to be connected to a smoke treatment device not shown.

L'espace annulaire 21 renferme des parois verticales 23 dƩlimitant des canaux communiquant entre eux de faƧon que les fumƩes viennent en contact avec toute la surface extƩrieure de la paroi latƩrale 3 de la cuve et assurent ainsi un chauffage uniforme du produit 2.The annular space 21 contains vertical walls 23 defining channels communicating with each other so that the fumes come into contact with the entire outer surface of the side wall 3 of the tank and thus provide uniform heating of the product 2.

Afin d'Ć©viter les dĆ©perditions de chaleur, l'espace annulaire 21 est dĆ©limitĆ© extĆ©rieurement par une paroi cylindrique 24 revĆŖtue extĆ©rieurement d'un matĆ©riau isolant 2.5 situĆ© dans une enveloppe de protection 26.In order to prevent heat losses, the annular space 21 is delimited externally by a cylindrical wall 24 coated externally with an insulating material 2.5 situated in a protective envelope 26.

Pour ĆŖtre complet, on ajoutera que la cuve 1 est pourvue Ć  sa partie infĆ©rieure d'un orifice non reprĆ©sentĆ© qui est prĆ©vu pour permettre l'Ć©vacuation du produit lorsque celui-ci est homogĆ©nĆ©isĆ© et se trouve Ć  l'Ć©tat liquide ou pĆ¢teux souhaitĆ©.To be complete, it will be added that the tank 1 is provided at its lower part with a not shown orifice which is provided to allow the evacuation of the product when the latter is homogenized and is in the desired liquid or pasty state.

La cuve est Ć©galement pourvue d'une sonde non reprĆ©sentĆ©e permettant de rĆ©gler la tempĆ©rature du produit grĆ¢ce Ć  une commande appropriĆ©e du brĆ»leur 19.The tank is also provided with a not shown probe for regulating the temperature of the product by appropriate control of the burner 19.

Le fondoir qui vient d'ĆŖtre dĆ©crit assure une homogĆ©nĆ©isation parfaite et rapide du produit.The melter just described ensures a perfect homogenization and fast product.

En effet, lorsque le moteur 14 entraƮne en rotation l'arbre 9, les disques 10, 11 et les pales 16 soumettent le produit Ơ une forte agitation en crƩant un vortex dans lequel le produit dƩcrit un mouvement ascendant le long de la paroi latƩrale 3 de la cuve et un mouvement descendant le long de l'arbre 9.Indeed, when the motor 14 rotates the shaft 9, the disks 10, 11 and the blades 16 subject the product to a strong stirring by creating a vortex in which the product describes a upward movement along the side wall 3 of the vessel and a downward movement along the shaft 9.

Pendant son mouvement descendant, le produit est brassƩ par les pales 16 et contraint en partie de traverser les trous 13 du disque supƩrieur 11 puis les trous 12 du disque infƩrieur 10.During its downward movement, the product is stirred by the blades 16 and forced in part to traverse the holes 13 of the upper disk 11 and the holes 12 of the lower disk 10.

GrĆ¢ce Ć  ces mouvements ascendant et descendant, le produit s'homogĆ©nĆ©ise rapidement et de faƧon optimale, la vitesse de rotation de l'arbre jouant un rĆ“le important.Thanks to these upward and downward movements, the product is homogenized quickly and optimally, the rotational speed of the tree playing an important role.

Le fondoir assure Ʃgalement un chauffage uniforme et rƩgulier du produit, l'espace annulaire 21 organisƩ en canaux permettant cette uniformisation.The melter also ensures uniform and regular heating of the product, the annular space 21 organized into channels allowing this uniformity.
