Abstract

The safety device is used in reservoirs of the type that have a float valve interposed between the upper part of the barrel and the suction pipe. The valve (7) is pushed by a float (8), independent of the valve, towards a sleeve (10) which extends towards the base of the usual centre (4). The diameter of the sleeve is greater than that of the valve. The sleeve is preferably disposed between the centre and the shaft (9). The float and the valve comprise two identical balls. USE - Liquid reservoirs especially barrels, casks etc.. Prevents particles in liquid from reaching pump.

Description

La présente invention est relative à un dispositif de sécurité pour réservoir de liquide. The present invention relates to a safety device for a liquid reservoir.

La présente invention est plus particulièrement, mais non exclusivement, destinée à équiper des tonnes à lisier. The present invention is more particularly, but not exclusively, intended to equip slurry tonnes.

Le remplissage d'une tonne à lisier est réalisé en effectuant le vide à l'intérieur, ladite tonne présentant, à cet effet, un orifice d'aspiration à sa partie supérieure. The filling of a slurry tanker is carried out by vacuuming the interior, said tank having, for this purpose, a suction port at its upper part.

Le problème qui se pose est double, le premier consiste à stopper la pompe lorsque le réservoir de la tonne est plein et le second consiste à empêcher que le lisier et les particules qu'il contient parviennent à ladite pompe. The problem which arises is twofold, the first consists in stopping the pump when the tank of the ton is full and the second consists in preventing that the slurry and the particles which it contains reach this pump.

Le premier problème a été résolu de façon satisfaisante, mais il n'en est pas de même en ce qui concerne le second. The first problem has been satisfactorily resolved, but it is not the same with the second.

En l'état actuel de la technique on interpose une sécurité, voire plusieurs, entre l'orifice supérieur du réservoir et la pompe. In the current state of the art, a safety device, or even several, is interposed between the upper orifice of the reservoir and the pump.

Le principe général d'une telle sécurité consiste à utiliser un clapet à flotteur. Lorsque le liquide repousse le flotteur celui-ci est plaqué contre son siège et obture la canalisation d'aspiration. The general principle of such safety consists in using a float valve. When the liquid repels the float, it is pressed against its seat and closes the suction pipe.

Cependant, comme le flotteur est situé dans un espace où on crée une dépression, celle-ci doit être sans effet sur le déplacement dudit flotteur. De ce fait, le flotteur est guidé dans un puits situé dans un manchon reliant la partie supérieure de la cuve et la canalisation d'aspiration. However, as the float is located in a space where a depression is created, this must have no effect on the movement of said float. Therefore, the float is guided in a well located in a sleeve connecting the upper part of the tank and the suction pipe.

Ce dispositif ne s'oppose pas totalement à ce que du lisier et des impuretés parviennent jusqu'à la pompe car, lorsque le liquide commence à soulever le flotteur, il faut un certain temps pour que celuici soit plaqué contre son siège, poussé par le liquide, et les flocons qui surnagent toujours au-dessus du liquide sont aspirés pendant ce temps. This device is not totally opposed to slurry and impurities reaching the pump because, when the liquid begins to lift the float, it takes a while for it to be pressed against its seat, pushed by the liquid, and the flakes that still float above the liquid are sucked off during this time.

La présente invention, qui remédie à ces inconvénients, est remarquable en ce que le flotteur est surmonté d'un clapet qui, sous la poussée dudit flotteur, pénétre dans un conduit comportant le siège usuel à sa partie supérieure. The present invention, which overcomes these drawbacks, is remarkable in that the float is surmounted by a valve which, under the thrust of said float, enters a duct comprising the usual seat at its upper part.

Le flotteur et le clapet sont constitués par deux boules identiques du genre de celles utilisées dans les dispositifs connus pour former, à la fois, le flotteur et le clapet.  The float and the valve consist of two identical balls of the kind used in known devices to form both the float and the valve.

I1 est à noter que selon l'invention, le flotteur et le clapet sont deux organes totalement séparés. It should be noted that according to the invention, the float and the valve are two completely separate members.

La présente invention sera mieux comprise par la description qui va suivre faite en se référant au dessin annexé à titre d'exemple indicatif seulement sur lequel
-la figure 1 est une vue en coupe, très schématique, d'un dispositif de sécurité connu
-la figure 2 est une vue, analogue à celle 1, montrant le dispositif de l'invention;
-la figure 3 est une vue, analogue à celle 2, montrant l'obturation de la canalisation d'aspiration.The present invention will be better understood from the description which follows made with reference to the attached drawing by way of indicative example only, in which
FIG. 1 is a very schematic sectional view of a known safety device
FIG. 2 is a view, similar to that 1, showing the device of the invention;
FIG 3 is a view, similar to that 2, showing the closure of the suction pipe.

En se reportant à la figure 1, on voit que la canalisation d'aspiration 1 est reliée au réservoir 2, dont le remplissage est envisagé en créant le vide à l'intérieur, par l'entremise d'un manchon 3. Referring to FIG. 1, it can be seen that the suction pipe 1 is connected to the tank 2, the filling of which is envisaged by creating the vacuum inside, by means of a sleeve 3.

Le manchon 3 présente, à sa partie supérieure, un siège 4 pouvant être obturé par un clapet-flotteur 5, constitué par une boule en caoutchouc par exemple. The sleeve 3 has, at its upper part, a seat 4 which can be closed off by a float valve 5, constituted by a rubber ball for example.

Durant le remplissage la boule 5 repose sur le fond d'un puits de guidage 6 dont la paroi est totalement ajourée pour ne pas gêner l'aspiration. During filling the ball 5 rests on the bottom of a guide well 6 whose wall is completely perforated so as not to interfere with the suction.

Afin que la boule 5 ne soit pas aspirée, le diamètre du manchon 3 est bien supérieur à celui du puits 6. So that the ball 5 is not sucked in, the diameter of the sleeve 3 is much greater than that of the well 6.

Lorsque le niveau N du liquide dans le réservoir 2 atteint la boule 5, celle-ci est repoussée vers le haut mais les flocons, composés de particules liquides et solides qui surnagent toujours à la surface du liquide, pénètrent dans le manchon 3 et sont aspirés avant que ladite boule 5 atteigne le siège 4 avec tous les inconvénients que celà peut présenter pour la pompe. When the level N of the liquid in the reservoir 2 reaches the ball 5, it is pushed upwards but the flakes, composed of liquid and solid particles which always float on the surface of the liquid, penetrate into the sleeve 3 and are sucked before said ball 5 reaches seat 4 with all the disadvantages that this may present for the pump.

Selon l'invention, on utilise un dispositif de sécurité, qui s'inspire de celui décrit en regard de la figure 1 en ce sens qu'il présente un manchon 3, interposé entre la canalisation d'aspiration 1 et le réservoir 2, comportant un puits et un siège 4 pour un clapet 7. According to the invention, a safety device is used, which is inspired by that described with reference to FIG. 1 in that it has a sleeve 3, interposed between the suction pipe 1 and the tank 2, comprising a well and a seat 4 for a valve 7.

Sous le clapet 7 est disposé un flotteur 8. Le clapet 7 et le flotteur 8 sont guidés dans un puits 9, analogue à celui 6. Le clapet et le flotteur peuvent être constitués de deux boules identiques et analogues à celle 5 connue.  Under the valve 7 is arranged a float 8. The valve 7 and the float 8 are guided in a well 9, similar to that 6. The valve and the float may be made up of two identical balls and analogous to that known 5.

Entre le siège 4 et la partie supérieure du puits 9 est interposée une virole 10 dont le diamètre est sensiblement égal à celui du puits 9, c'est-à-dire qu'elle présente un diamètre qui est légérèrement supérieur à celui des boules 7 et 8. Between the seat 4 and the upper part of the well 9 is interposed a ferrule 10 whose diameter is substantially equal to that of the well 9, that is to say that it has a diameter which is slightly greater than that of the balls 7 and 8.

Lorsque le flotteur 8 est poussé par le liquide il repousse le clapet 7 et l'engage dans la virole 10. A ce moment, il ne subsiste plus entre le clapet 7 et la virole 10, qu'un espace annulaire 1 1 dont la section est réduite et la dépression qui régne dans ladite virole est suffisante pour aspirer violemment le clapet 7 et le plaquer contre le siège 4 (figure 3). When the float 8 is pushed by the liquid it pushes the valve 7 and engages it in the shell 10. At this time, there remains no more between the valve 7 and the shell 10, only an annular space 11 whose section is reduced and the vacuum prevailing in said ferrule is sufficient to violently suck the valve 7 and press it against the seat 4 (Figure 3).

Cette action est quasi instantanée.This action is almost instantaneous.

Compte tenu de la rapidité de l'obturation, les flocons qui
surnagent n'ont pas le temps de s'élever, poussés par le liquide, et d'être
aspirés car, comme cela ressort de la figure 3, le niveau N du liquide
dans le manchon 3 est relativement éloigné du siège 4. Given the speed of the shutter, the flakes that
do not have time to rise, pushed by the liquid, and to be
sucked because, as shown in Figure 3, the level N of the liquid
in the sleeve 3 is relatively far from the seat 4.
