Abstract

The doser includes a dosing tank (4) filled by gravity feed from a liquid reservoir (1) a refilling pipe with an anti-return valve (3). Also provided is a sliding pipe (5) with an air cock (6), a compressed air admission tube (13), and a liquid ejection pipe (9) with a further non-return valve (10). The liquid flows into the dosing tank while the air cock is open but stops when it reaches the bottom of the sliding pipe causing the pipe to shut. To empty the dosing tank a valve (12) is opened allowing the entry of compressed air. This closes the anti-return valve (3) controlling the dosing liquid and also keeps the drain valve closed. The dosing liquid is then forced out through the ejection pipe which is finally closed by a valve (14) to prevent the ejection of air.

DESCRIPTION
La présente invention concerne un dispositif pour doser avec précision un volume de liquide et à l'injecter sous pression à un moment déterminé.DOSRR vOuMnRIQ (J
a EJEcsIoN under PRESSURE FOR LIQUID
DESCRIPTION
The present invention relates to a device for accurately dosing a volume of liquid and injecting it under pressure at a determined time.

Dans les installations industrielles ou agricoles comportant des circuits de distribution, il faut parfois apporter un complément de manière ponctuelle et en des points variables du circuit. In industrial or agricultural installations with distribution circuits, it is sometimes necessary to provide occasional and variable points in the circuit.

Par exemple, dans le cas d'une installation de nourrissage d'animaux, l'éleveur doit apporter une solution vétérinaire d'appoint dans le circuit général d'alimentation de tout un élevage. I1 manque un dispositif autonome et automatique susceptible d'être posé en différents points pour la durée d'un traitement en cas de soin dans une case particulière. Pour l'instant seule une intervention manuelle de l'éleveur permet de résoudre ce problème, avec tous les aléas de l'urgence, de l'oubli, de la disponibilité. For example, in the case of an animal feeding facility, the farmer must provide a supplementary veterinary solution in the general feeding circuit of an entire farm. I1 lacks an autonomous and automatic device capable of being placed at different points for the duration of a treatment in the event of treatment in a particular box. For now only manual intervention by the breeder can resolve this problem, with all the vagaries of urgency, forgetfulness, availability.

Or ces traitements ne sont efficaces que s'ils sont assurés avec une grande rigueur de posologie et de régularité.However, these treatments are only effective if they are provided with great rigor in dosage and regularity.

Le dispositif, selon l'invention, permet de remédier à cet inconvénient : apports de produits, de traitements divers, de compléments, avec asservissement à une chaîne de distribution. The device according to the invention makes it possible to remedy this drawback: supply of products, various treatments, supplements, with slaving to a distribution chain.

I1 peut aussi fonctionner de manière autonome et avoir son propre programme : temporisateur, détections diverses (hygrométrie, température, détecteurs de niveau, de présence, etc.)
I1 est constitué
- d'un réservoir (4) formant corps de l'appareil,
- d'un système de remplissage (2 et 3),
- d'un système de dosage (5 et 6),
- d'un système d'éjection (9, 10, et 11),
- d'un système de fermeture (14). I1 can also operate independently and have its own program: timer, various detections (humidity, temperature, level, presence detectors, etc.)
I1 is made up
- a reservoir (4) forming the body of the device,
- a filling system (2 and 3),
- a dosing system (5 and 6),
- an ejection system (9, 10, and 11),
- a closure system (14).

Le réservoir (4), dont la capacité peut être variable, se présente sous la forme d'une cuve munie d'un couvercle (15) équipée des appareils ci-après
- un système de remplissage (2 et 3) par simple chute dans un
tuyau à partir d'une ou plusieurs réserve(s)-mère(s) (1)
placée(s) à un niveau supérieur ou à partir d'un branchement,
- un système de dosage comportant un tuyau (5) surmonté d'un
purgeur à flotteur (6), réglable au moyen d'une échelle
graduée (7), et de l'index (8), le tuyau (5) étant coulissant.The tank (4), the capacity of which can be variable, is in the form of a tank provided with a cover (15) equipped with the following devices
- a filling system (2 and 3) by simple fall into a
hose from one or more mother reserve (s) (1)
placed on a higher level or from a connection,
- a dosing system comprising a pipe (5) surmounted by a
float trap (6), adjustable by means of a scale
graduated (7), and the index (8), the pipe (5) being sliding.

- un système d'éjection comprenant un tuyau plongeur (9) muni
d'un clapet anti-retour (10) servant également de soupape,
ainsi que d'un tuyau d'amenée d'air comprimé (13) et d'une
vanne de commande (12),
- un système de fermeture constitué d'un flotteur (14).- an ejection system comprising a plunger pipe (9) provided
a non-return valve (10) also serving as a valve,
as well as a compressed air supply pipe (13) and a
control valve (12),
- a closure system consisting of a float (14).

Le dispositif fonctionne comme suit
- Le remplissage : le purgeur (6) est en position ouverte
et met la cuve du doseur à la pression atmosphérique. Le
liquide tombe de la réserve (1) par sa propre masse. Lorsque
le niveau du liquide atteint la partie inférieure du tuyau
(5) , il remonte dans celui-ci et va pousser le flotteur du
purgeur (6) qui obstrue l'échappée d'air. L'équilibre
de pression se fait. Le niveau est stabilisé.The device works as follows
- Filling: the trap (6) is in the open position
and puts the metering tank at atmospheric pressure. The
liquid falls from the reserve (1) by its own mass. When
the liquid level reaches the bottom of the pipe
(5), it goes back into it and will push the float of the
trap (6) which obstructs the escape of air. The balance
pressure is done. The level has stabilized.

- Ce niveau est préalablement déterminé à l'aide de l'index
(8) sur l'échelle graduée (7). La soupape (10) est mainte
nue en position fermée par un ressort taré à une pression
supérieure à la pression de la masse de liquide de la cuve
mère. L'appareil est ainsi muni du contenu demandé et se
trouve en situation d'attente.- This level is determined beforehand using the index
(8) on the graduated scale (7). The valve (10) is held
bare in closed position by a spring calibrated at a pressure
greater than the pressure of the mass of liquid in the tank
mother. The device is thus provided with the requested content and is
is in a waiting situation.

- Sur commande d'ouverture par la vanne (12) l'air comprimé
entre dans la cuve, ce qui a pour effet de fermer le clapet
anti-retour (3) , de maintenir le flotteur du purgeur (6)
en position fermée, de pousser la masse de liquide par le tube
d'évacuation (9) , provoquant ainsi l'ouverture de la soupape
(10) et la sortie sous pression par le tuyau (11). La
soupape (10) sert également de clapet anti-retour.- On opening command by the valve (12) compressed air
enters the tank, which has the effect of closing the valve
non-return (3), maintain the trap float (6)
in the closed position, push the mass of liquid through the tube
evacuation (9), thereby opening the valve
(10) and the pressurized outlet through the pipe (11). The
valve (10) also serves as a non-return valve.

- En fin d'évacuation de liquide, le flotteur (14) retombe
sur son siège et interdit le passage de l'air.- At the end of the liquid discharge, the float (14) falls back
on his seat and prohibits the passage of air.

- Après coupure d'air par la vanne à échapper (12) , le flot
teur du purgeur (6) retombe et permet l'évacuation d'air et
un nouveau remplissage pour le cycle suivant. - After the air has been cut off by the escape valve (12), the flow
steam trap (6) falls back and allows the evacuation of air and
a new filling for the next cycle.

Un tel dispositif est particulièrement adapté à des circuits d'alimentation du bétail, de traitement des cultures, qui exigent de plus en plus de dosages précis pour des raisons économiques, écologiques, et du fait de réglementations aux nouvelles normes européennes. Such a device is particularly suitable for livestock feeding circuits, crop treatment, which increasingly require precise dosages for economic, ecological reasons, and due to regulations to new European standards.

Mais il peut répondre à de multiples applications dans le monde industriel, car il présente l'avantage d'une grande souplesse d'adaptation et de mise en service.  But it can respond to multiple applications in the industrial world, because it has the advantage of great flexibility of adaptation and commissioning.
