Abstract
Description
La présente invention porte sur un tambour chauffant pour transporteurs, convoyeurs à bandes ou analogues, destinés au transport de matériaux par exemple dans des carrières, sablières, cokeries ou autres sites. The present invention relates to a heating drum for conveyors, conveyor belts or the like, intended for the transport of materials for example in quarries, sand pits, coking plants or other sites.
Les installations de ce type fonctionnent en extérieur et sont soumises aux intempéries, notamment aux fortes gelées. Installations of this type operate outdoors and are subject to inclement weather, especially severe frost.
Pour palier les inconvénients qui en résultent, certaines installations sont équipées de sources de chaleur diverses par exemple - rangées de brûleurs, - ventilateur à air chaud, - résistances électriques, etc... To overcome the drawbacks which result therefrom, certain installations are equipped with various heat sources for example - rows of burners, - hot air fan, - electrical resistances, etc.
toutes placées sur le parcours du convoyeur ou du transporteur.all placed on the path of the conveyor or transporter.
Elles ne sont généralement pas intégrées à l'installation et visent à réchauffer les produits ou matériaux ou à conserver leurs propriétés, c'est le cas des installations décrites dans les documents
FR 2 257 507 et FR 2 569 260.They are generally not integrated into the installation and aim to heat the products or materials or to preserve their properties, this is the case of the installations described in the documents.
FR 2 257 507 and FR 2 569 260.
Par ailleurs, on connaît des installations à source de chaleur intégrée, en particulier des sources de chaleur intégrees dans le mécanisme de tambours malaxeurs, par exemple dans les documents
EP 146939 qui comporte des radiateurs de rayons IR et, WO 89 03914 qui comporte des résistances chauffants.Furthermore, there are known installations with an integrated heat source, in particular heat sources integrated into the mixer drum mechanism, for example in documents.
EP 146939 which includes radiators for IR rays, and WO 89 03914 which includes heating resistors.
Comme précédemment, les moyens de chauffage sont destinés aux matériaux transportés et non à l'appareil lui-même. As before, the heating means are intended for the materials transported and not for the device itself.
Or, lors de la mise en mouvemelnt des transporteurs ou convoyeurs à bande, il se produit par temps froid un manque d'adhérence, ou patinage, au niveau de tambour de motorisation. However, during the setting in motion of conveyors or belt conveyors, there occurs in cold weather a lack of grip, or slippage, at the level of the motorized drum.
Actuellement, on remédie à cet inconvénient par des moyens chauffants tel que radiateur infrarouge, chalumeau, ou brasero que l'on installe à proximité du tambour. Currently, this drawback is remedied by heating means such as an infrared radiator, torch, or brazier which is installed near the drum.
Ces moyens présentent de nombreux inconvénients - perte de temps, - perte de production, - manque à gagner, - manque de sécurité et de fiabilité, - réglage de puissance difficile ou impossible. These means have numerous drawbacks - loss of time, - loss of production, - loss of profit, - lack of security and reliability, - power adjustment difficult or impossible.
Dans le but de palier tous ces inconvénients la présente invention consiste à introduire une source de chaleur variable et réglable à l'intérieur même du tambour de motorisation du convoyeur. In order to overcome all these drawbacks, the present invention consists in introducing a variable and adjustable heat source inside the motorized drum of the conveyor.
Plus particulièrement le moyen de chauffage est un moyen a résistances électriques de chauffage qui traversent un des flasques qui leur sert de support, et qui s'étendent sous la face interne de la surface cylindrique du tambour (2). De préférence les contacts électriques des résistances sont assurés par un commutateur rotatif deux pôles et un embrayage magnétique (8), l'ensemble étnat protégé par un capot de protection (9). More particularly, the heating means is a means with electrical heating resistances which pass through one of the flanges which serves as their support, and which extend under the internal face of the cylindrical surface of the drum (2). Preferably, the electrical contacts of the resistors are provided by a two-pole rotary switch and a magnetic clutch (8), all of which are protected by a protective cover (9).
On comprendra mieux l'invention à l'aide de la description qui suit faite en référence aux figures annexées suivantes - figure 1 : vue en coupe longitudinale d'un tambour chauffant selon l'invention ; - figure 2 : section A-A de la figure 1. The invention will be better understood using the following description made with reference to the following appended figures - FIG. 1: view in longitudinal section of a heating drum according to the invention; - Figure 2: section A-A of Figure 1.
Le mode de réalisation représenté n'est pas limitatif, il comporte essentiellement un ensemble mécanique, un ensemble électrique et un ensemble de sécurité. The embodiment shown is not limiting, it essentially comprises a mechanical assembly, an electrical assembly and a safety assembly.
L'ensemble mécanique comporte de façon classique un tambour de motorisation (2) pour l'entrainement et le renvoi d'une bande transporteuse non représentée. Le tambour de motorisation (2) est monté à rotation sur un arbre (1) longitudinal porté à chaque extrémité par un roulement (3) et solidarisé aux flasques (4) verticaux d'extrémité du tambour. The mechanical assembly conventionally comprises a motorized drum (2) for driving and returning a not shown conveyor belt. The motorization drum (2) is mounted for rotation on a longitudinal shaft (1) carried at each end by a bearing (3) and secured to the vertical end plates (4) of the drum.
Une poulie (5) montée à une des extrémités de l'arbre (1) lui communique le couple de rotation d'un moteur non représenté. A pulley (5) mounted at one end of the shaft (1) communicates to it the torque of a motor not shown.
L'ensemble électrique de chauffage comporte de préférence trois ensembles résistances-thermocouples (6) parallèles dont les contacts sont assurés par un commutateur rotatif deux pôles et coopérant avec un embrayage magnétique (8), et protégés par un capot de protection (9). The electrical heating assembly preferably comprises three resistance-thermocouple (6) parallel assemblies, the contacts of which are provided by a two-pole rotary switch and cooperating with a magnetic clutch (8), and protected by a protective cover (9).
Les trois resistances-thermocouples (6) traversent un des flasques qui leur sert de support, par exemple celui qui est le plus proche de la poulie (5). The three thermocouple resistors (6) pass through one of the flanges which serves as their support, for example that which is closest to the pulley (5).
Les résistances-thermocouples (6) sont ainsi placées à l'intérieur du tambour (2), à distance appropriée de sa face interne cylindrique, elles s'étendent sur une grande partie de la longueur du tambour et son réparties angulairement régulièrement à 1200 d'angle pour cet exemple. The thermocouple resistors (6) are thus placed inside the drum (2), at an appropriate distance from its cylindrical internal face, they extend over a large part of the length of the drum and its angularly distributed regularly at 1200 d 'angle for this example.
Cet ensemble électrique de chauffage est totalement étanche, isolé électriquement et protégé mecaniquement, il peut être commandé en temps voulu par un opérateur qui peut également choisir et modifier la puissance de chauffage. This electric heating assembly is completely sealed, electrically insulated and mechanically protected, it can be controlled in due time by an operator who can also choose and modify the heating power.
On peut aussi prévoir une régulation automatique. It is also possible to provide automatic regulation.
L'ensemble de sécurité est composé d'une soupape ou d'un évent (10) placé sur l'un ou l'autre des deux flasques (4) pour l'évacuation de l'air chaud et/ou des buées. The safety assembly is composed of a valve or a vent (10) placed on one or the other of the two flanges (4) for the evacuation of hot air and / or mist.
Par ailleurs, le flasque qui ne porte pas les resistances est démontable pour une intervention pratique et rapide en cas de défaillance ou de détérioration de l'un des éléments chauffants. In addition, the flange which does not carry the resistors is removable for a practical and rapid intervention in the event of failure or deterioration of one of the heating elements.
Des variantes peuvent être apportées à ce dispositif, notamment concernant le type de source de chauffage, le nombre d'éléments chauffant, sans pour autant sortir du cadre de l'invention. Variants can be made to this device, in particular concerning the type of heating source, the number of heating elements, without going beyond the ambit of the invention.
Les avantages de l'invention sont importants en particulier - gain de temps et de productivité, - facilité d'emploi et de réglage en temperature, - bonnes fiabilité et sécurité, - facilité d'entretien The advantages of the invention are important in particular - saving time and productivity, - ease of use and temperature adjustment, - good reliability and safety, - ease of maintenance
