Abstract
Description
La présente invention concerne de façon générale un appareil d'échantillonnage de liquide et plus précisément un appareil d'échantillonnage des matières grasses du lait. The present invention relates generally to a liquid sampling apparatus and more specifically to a milk fat sampling apparatus.
On connaît déjà divers types d'appareils d'échantillonnage de liquide et notamment un appareil d'échantillonnage des matières grasses du lait. La technique antérieure est représentée par les brevets des Etats-Unis d'Amérique n" 3 965 749, 3 250 129, 3 504 549, 4 167 117, 3 897 687, 4 131 011 et 4 118 987, le brevet français n" 73.40381 et le brevet australien n" 544 870. Various types of liquid sampling apparatus are already known, and in particular a milk fat sampling apparatus. The prior art is represented by United States patents 3,965,749, 3,250,129, 3,504,549, 4,167,117, 3,897,687, 4,131,011 and 4,118,987, French patent no. 73.40381 and Australian Patent No. 544,870.
Le brevet australien n" 544 870 décrit et revendique un ensemble de prélèvement d'échantillons de liquides, comprenant un ensemble de prélèvement d'échantillons d'une canalisation dans laquelle le liquide s'écoule avec un courant pulsé, c'est-à-dire qu'il existe des périodes sans écoulement, l'ensemble comprenant une canalisation montée en dérivation dans la canalisation principale et rejoignant un tronçon de la canalisation principale qui est a une pression supérieure a celle d'un tronçon qui est a une plus faible pression, une chambre étant formée dans la canalisation en dérivation et etant remplie à chaque impulsion du courant, la quantité de liquide supérieure à la capacité de la chambre s'écoulant dans le tronçon à plus faible pression et la chambre étant vidée par écoulement par gravité par un passage rejoignant un reservoir d'échantillonnage, le passage ayant des dimensions telles que la chambre se vide chaque fois avant l'apparition d'une impulsion suivante. Australian Patent No. 544,870 describes and claims a set for taking samples of liquids, comprising a set for taking samples from a pipe in which the liquid flows with a pulsed current, that is to say say that there are periods without flow, the assembly comprising a pipe mounted as a diversion in the main pipe and joining a section of the main pipe which is at a higher pressure than that of a section which is at a lower pressure , a chamber being formed in the bypass pipe and being filled at each pulse of the current, the quantity of liquid greater than the capacity of the chamber flowing in the section at lower pressure and the chamber being emptied by gravity flow by a passage joining a sampling reservoir, the passage having dimensions such that the chamber is emptied each time before the appearance of an impulse next ion.
On a constaté que, pour des débits élevés, la chambre ne se vidait pas totalement dans le réservoir d'échantillonnage. En conséquence, le liquide du réservoir d'échantillonnage peut ne pas représenter avec précision le liquide circulant dans l'appareil d'échantillonnage. It has been found that, for high flow rates, the chamber does not empty completely in the sampling tank. As a result, the liquid in the sampling tank may not accurately represent the liquid flowing through the sampling device.
L'invention - concerne un appareil perfectionné d'échantillonnage de liquide, du type décrit dans le brevet australien n0 544 870 et qui ne pose pas le problème de la vidange incomplète de la chambre dans le réservoir d'échantillonnage et qui permet donc un échantillonnage de plus grande précision, notamment pour des débits relativement élevés. The invention relates to an improved liquid sampling device, of the type described in Australian patent No. 544 870 and which does not pose the problem of incomplete emptying of the chamber in the sampling tank and which therefore allows sampling. greater accuracy, especially for relatively high flow rates.
Dans un mode de réalisation préféré, l'invention concerne donc un appareil d'échantillonnage particulierement destiné a être utilisé avec une canalisation principale ayant une partie amont qui est à une pression relativement élevée et une partie aval qui est a une pression relativement faible, une chambre destinée a recevoir un liquide, ayant une entre qui communique avec la partie amont et une sortie de débordement qui communique avec la partie aval, une chambre d'échantillonnage placée audessous de la chambre de réception de liquide, un conduit de circulation par gravité assurant la communication entre la chambre de réception de liquide et la chambre d'Fchan- tillonnage et étant destiné a permettre l'écoulement du liquide sous l'action des forces de pesanteur de la chambre de réception de liquide a la chambre d'échantillonnage, et un conduit d'évacuation d'air allant de la chambre d'échantillonnage à la chambre de réception de liquide et destiné à empêcher le piégeage de l'air dans la chambre d'échantil- lonnage lorsqu'il est transmis de la chambre de réception de liquide par l'intermédiaire du conduit de circulation sous l'action de la pesanteur. In a preferred embodiment, the invention therefore relates to a sampling device particularly intended for use with a main line having an upstream part which is at a relatively high pressure and a downstream part which is at a relatively low pressure, a chamber intended to receive a liquid, having an inlet which communicates with the upstream part and an overflow outlet which communicates with the downstream part, a sampling chamber placed below the liquid receiving chamber, a gravity circulation pipe ensuring the communication between the liquid receiving chamber and the sampling chamber and being intended to allow the liquid to flow under the action of gravity forces from the liquid receiving chamber to the sampling chamber, and an air exhaust duct from the sampling chamber to the liquid receiving chamber and intended to prevent er trapping the air in the sampling chamber when it is transmitted from the liquid receiving chamber via the circulation duct under the action of gravity.
Dans un mode de réalisation préféré de l'invention, l'appareil d'échantillonnage de liquide fait partie d'une machine automatique de traite et la canalisation principale est une partie d'une canalisation de sortie couplée a un faisceau-trayeur. In a preferred embodiment of the invention, the liquid sampling apparatus is part of an automatic milking machine and the main line is a part of an outlet line coupled to a milking cluster.
D'autres caractéristiques et avantages de l'invention ressortiront mieux de la description qui va suivre, faite en référence au dessin annexé sur lequel la figure unique représente, en partie en perspective et en partie sous forme de schéma, un appareil d'échantillonnage de liquide ayant une construction et un fonctionnement selon un mode de réalisation préféré de l'invention Et faisant partie d'une machine automatique de traite. Other characteristics and advantages of the invention will emerge more clearly from the description which follows, given with reference to the appended drawing in which the single figure represents, partly in perspective and partly in diagram form, a sampling device of liquid having a construction and an operation according to a preferred embodiment of the invention And forming part of an automatic milking machine.
On se réfère b la figure qui est une perspective partielle et un schéma partiel d'un appareil d'6chantillon- nage de liquide dont la construction et le fonctionnement correspondent a un mode de réalisation préféré de l'invention, dans le cadre d'une machine de traite automatique. Il faut noter que l'appareil d'échantillonnage de liquide de l'invention n'est pas limité au lait ni aux machines de traite ou trayeuses, mais est particulierement utile dans le cadre d'une trayeuse automatique. Reference is made to the figure which is a partial perspective and a partial diagram of a liquid sampling apparatus, the construction and operation of which correspond to a preferred embodiment of the invention, within the framework of a automatic milking machine. It should be noted that the liquid sampling device of the invention is not limited to milk or milking machines or milking machines, but is particularly useful in the context of an automatic milking machine.
Dans le mode de réalisation préféré, le lait d'un faisceau-trayeur 10 est transmis à une canalisation 12 de circulation de lait ayant une partie amont 14 dont le diamètre est tel que la section est relativement grande, la pression étant relativement élevée, et une partie aval 16 ayant un diamètre donnant une section relativement faible, et dans laquelle la pression est relativement faible. In the preferred embodiment, the milk from a milking cluster 10 is transmitted to a milk circulation pipe 12 having an upstream part 14 whose diameter is such that the section is relatively large, the pressure being relatively high, and a downstream part 16 having a diameter giving a relatively small section, and in which the pressure is relatively low.
Selon l'invention, un appareil 18 d'échantillonnage comprend une chambre 20 de réception de liquide, placée par exemple au-dessus de la canalisation 12 et communiquant avec la partie amont 14 par un conduit 22. La chambre 20 de réception communique aussi avec la partie aval 16 par un conduit 24 de débordement. According to the invention, a sampling device 18 comprises a chamber 20 for receiving liquid, placed for example above the pipe 12 and communicating with the upstream part 14 by a conduit 22. The receiving chamber 20 also communicates with the downstream part 16 by an overflow conduit 24.
L'appareil 18 d'échantillonnage comporte aussi une chambre 26 d'échantillonnage qui est placée au-dessous de la chambre 20 de réception de liquide et qui reçoit un courant de liquide de cette chambre 20, sous l'action de la pesanteur, par un conduit 28 d'orientation générale verticale et destiné a l'écoulement du liquide. Dans un mode de réalisation préféré de l'invention, un conduit 30 d'évacuation d'air assure aussi la communication de la chambre 26 d'échantillonnage a la chambre 20 de réception de liquide. The sampling apparatus 18 also includes a sampling chamber 26 which is placed below the liquid receiving chamber 20 and which receives a stream of liquid from this chamber 20, under the action of gravity, by a conduit 28 of generally vertical orientation and intended for the flow of the liquid. In a preferred embodiment of the invention, an air exhaust duct 30 also ensures communication from the sampling chamber 26 to the liquid reception chamber 20.
La disposition de ce conduit d'évacuation d'air empêche le piégeage d'air dans la chambre 26, car ce piégeage pourrait gêner l'écoulement du liquide de la chambre 20 a la chambre 26 sous l'action des forces de pesanteur.The arrangement of this air exhaust duct prevents the trapping of air in the chamber 26, since this trapping could hinder the flow of liquid from the chamber 20 to the chamber 26 under the action of gravity forces.
Selon une caractéristique particulière de l'invention, l'évacuation de l'air est réalisée à l'intérieur de l'appareillage d'échantillonnage qui est fermé par rapport å l'atmosphère et qui, pendant le fonctionnement, est sous pression, sans que des joints d'étanchéité ou des sas ne soient nécessaires a un fonctionnement convenable. According to a particular characteristic of the invention, the air is evacuated inside the sampling apparatus which is closed relative to the atmosphere and which, during operation, is under pressure, without that gaskets or airlocks are not necessary for proper operation.
I1 est bien entendu que l'invention n'a été décrite et représentée qu'à titre d'exemple préférentiel et qu'on pourra apporter toute équivalence technique dans ses élé- ments constitutifs sans pour autant sortir de son cadre. It is understood that the invention has only been described and represented by way of a preferred example and that any technical equivalence may be made in its constituent elements without going beyond its ambit.
