Abstract

The bitumen melter consists of an insulated housing (3,4) on a chassis (1) with a chamber (5) for the bitumen and a lid (6) to cover it. The heat is provided by a removable burner (7) with a control unit (12). At the opposite end of the housing there is a tap (15) linked to the chamber (5) and having a drain tile (16) which can be set so that the outlet from the chamber (5) is closed and an overflow outlet channel (17) is opened, so that excess bitumen can flow safely into a bucket placed below the tap. The tap is controlled by a bar (19) which is moved through an angle of 90 degrees to open the tap and close the overflow outlet at the same time. When the bar is released the tap closes automatically by means of springs (21) connected to the drain tile. Sufficient springs are employed so that the tap closes automatically even if one gets broken.

Description

Dispositif de prélèvement pour fondoir de bitume
L'invention concerne un dispositif de prélèvement ou pour fondoir de bitume, comportant un robinet de prélèvement, situé à l'opposé d'un brûleur à gaz et d'un dispositif de commande et dans lequel un canal de trop-plein est ouvert, lorsque ledit robinet est dans la position fermée.
Sampling device for bitumen melter
The invention relates to a device for sampling or for bitumen melter, comprising a sampling valve, located opposite a gas burner and a control device and in which an overflow channel is open, when said valve is in the closed position.

L'invention a pour but d'agencer un dispositif distributeur, qui satisfait aux nouvelles spécifications de sécurité, pour des fondoirs de bitume, à l'aide de moyens simples de manière que le robinet de distribution du dispositif distributeur se ferme automatiquement. The invention aims to arrange a dispensing device, which meets the new safety specifications, for bitumen melters, using simple means so that the dispensing valve of the dispensing device closes automatically.

Ce problème est résolu, conformément à l'invention, grâce au fait que le robinet de distribution est agencé de manière à se fermer automatiquement par l'intermédiaire d'un dispositif à ressorts. This problem is solved, in accordance with the invention, thanks to the fact that the dispensing valve is arranged so as to close automatically by means of a spring device.

De façon appropriée, le dispositif à ressorts est constitué par au moins un, deux ou un plus grand nombre de ressorts de traction, qui sont armés entre un élément de réception, fixé à un carter du fondoir de bitume, et une barrette fixée à une barre de fermeture prévue pour le robinet de prélèvement. Suitably, the spring device consists of at least one, two or a greater number of tension springs, which are armed between a receiving element, fixed to a casing of the bitumen melter, and a bar fixed to a closing bar provided for the sampling tap.

L'avantage de l'utilisation de plusieurs ressorts de traction, qui sont accessibles à tout moment, doit être vu dans le fait que lors de la rupture de l'un des ressorts, I'autre ressort ou les autres ressorts sont encore toujours à même de fermer le robinet de prélèvement, car les ressorts sont réalisés pour présenter une force élastique telle que l'un de ces ressorts garantit également la fonction de fermeture automatique du robinet de prélèvement, ce qui est nécessaire dans le cas d'un fonctionnement de chantiers à conditions sévères. The advantage of using several tension springs, which are accessible at all times, must be seen in the fact that when one of the springs breaks, the other spring or the other springs are still still at even to close the sampling valve, because the springs are made to present an elastic force such that one of these springs also guarantees the automatic closing function of the sampling valve, which is necessary in the case of an operation of sites with severe conditions.

D'autres caractéristiques et avantages de la présente invention ressortiront de la description donnée ci-après prise en référence aux dessins annexés, sur lesquels:
- la figure 1 est une coupe longitudinale schématique d'un fondoir à bitume; et
- la figure 2 est une vue prise dans la direction de la flèche Il sur la figure 1.
Other characteristics and advantages of the present invention will emerge from the description given below taken with reference to the appended drawings, in which:
- Figure 1 is a schematic longitudinal section of a bitumen melter; and
- Figure 2 is a view taken in the direction of the arrow II in Figure 1.

Un carter 3 possédant un isolant thermique 4 est supporté par un châssis inférieur 1. Une cuve 5 pour le bitume devant être fondu est montée dans le carter 3 et doit être fermée par un couvercle 6. Une unité de combustion 7 comportant un brûleur 8 est disposée au-dessous de la cuve 5, à l'intérieur du carter isolé 3. L'unité de combustion 7 peut être enlevée et remise en place, d'un seul tenant, avec un dispositif de commande 12. Une poignée 13 est située sur le carter 3 et un tube d'évacuation des fumées 14, qui est amovible ou qui peut être rabattu, est monté sur le carter 3. A casing 3 having a thermal insulator 4 is supported by a lower chassis 1. A tank 5 for the bitumen to be melted is mounted in the casing 3 and must be closed by a cover 6. A combustion unit 7 comprising a burner 8 is arranged below the tank 5, inside the insulated casing 3. The combustion unit 7 can be removed and replaced in one piece with a control device 12. A handle 13 is located on the casing 3 and a smoke evacuation tube 14, which is removable or which can be folded down, is mounted on the casing 3.

Sur le côté du carter 3, à l'opposé du dispositif de combustion 7, est disposé un robinet de prélèvement 15 relié à la cuve 5 et dont le boisseau 16 est agencé de telle sorte que dans la position fermée représentée, il interrompt la liaison avec la partie inférieure de la cuve 5 et relie un canal de trop-plein 17 du robinet de prélèvement 15 à un puits de trop-plein 18 de la cuve 5, de sorte qu'un éventuel trop-plein de bitume peut s'écouler, sans danger, dans un seau (non représenté) situé sous le robinet de prélèvement 15. On the side of the casing 3, opposite the combustion device 7, is arranged a sampling tap 15 connected to the tank 5 and whose plug 16 is arranged so that in the closed position shown, it interrupts the connection with the lower part of the tank 5 and connects an overflow channel 17 of the sampling valve 15 to an overflow well 18 of the tank 5, so that a possible overflow of bitumen can flow , without danger, in a bucket (not shown) located under the sampling tap 15.

Pour actionner le robinet de prélèvement 15 il est prévu une barre 19 de fermeture du robinet, que l'on déplace d'environ 90" dans le sens de la flèche 20 pour ouvrir le robinet de sortie 15. Dans cette position d'ouverture, le canal de trop-plein 17 du robinet de prélèvement 15 est fermé par le boisseau 16. To actuate the sampling valve 15, a bar 19 for closing the valve is provided, which is moved by approximately 90 "in the direction of the arrow 20 to open the outlet valve 15. In this open position, the overflow channel 17 of the sampling valve 15 is closed by the plug 16.

Afin que, comme des spécifications récentes le prescrivent, le robinet de prélèvement 15 se ferme automatiquement, lorsque la barre de fermeture 19 est relâchée, il est prévu de préférence plusieurs (ici deux) ressorts de traction 21. In order that, as recent specifications require, the sampling tap 15 closes automatically, when the closing bar 19 is released, there are preferably provided several (here two) tension springs 21.

Ces ressorts de traction 12 sont armés entre une barrette 22 fixée à la barre de fermeture 19 et une partie de réception 23 fixée au carter 3 de la cuve 5. Comme cela a déjà été mentionné, la présence de plusieurs ressorts 21 présente l'avantage en ce que, dans le cas d'une rupture de l'un des ressorts, le ou les autres ressorts peuvent toujours encore fermer automatiquement le robinet de prélèvement 15, étant donné que les ressorts de traction 21 sont agencés de façon correspondante. These tension springs 12 are armed between a bar 22 fixed to the closing bar 19 and a receiving part 23 fixed to the casing 3 of the tank 5. As already mentioned, the presence of several springs 21 has the advantage in that, in the event of a rupture of one of the springs, the other spring or springs can still still automatically close the draw-off valve 15, since the tension springs 21 are arranged in a corresponding manner.
