Description

La présente invention a pour objet un procédé de distribution d'un savon liquide et une machine pour la mise en oeuvre du procédé.The present invention relates to a method for dispensing a liquid soap and a machine for implementing the method.

Pour rappel, les matières solides à granulométrie fine, flottantes et se déposant dans le fond d'un récipient, qu'il s'agit de disperser ou d'acheminer dans des liquides, ne peuvent être introduites que difficilement dans ces liquides avec une homogénéité suffisante. Dès qu'elles entrent en contact avec les pellicules de liquide au repos, elles ont tendance à former des agglutinations adhésives. En outre, les matières solides ayant une densité plus élevée que le liquide environnant, elles se sédimentent lorsque la vitesse du courant est insuffisante et colmatent ainsi les organes d'arrêt ou d'obturation et les conduites d'alimentation et de distribution.As a reminder, solid particles with fine particle size, floating and depositing at the bottom of a container, which must be dispersed or conveyed in liquids, can only be introduced with difficulty into these liquids with homogeneity. sufficient. As soon as they come into contact with the films of liquid at rest, they tend to form adhesive agglutinations. In addition, since solid materials have a higher density than the surrounding liquid, they sediment when the speed of the current is insufficient and thus clog the stop or shutter members and the supply and distribution lines.

Dans un procédé présentement connu, la matière sous forme de poudre extrêmement fine et dure est maintenue en mouvement sur le fond d'un réservoir, de sorte qu'elle peut ruisseler en chute libre au travers d'une ouverture pratiquée dans le fond d'un récipient et débouchant dans une tubulure d'entrée d'une buse d'injection qui distribue par courant d'air la matière pulvérulente venant en mélange avec un liquide.In a presently known process, the material in the form of an extremely fine and hard powder is kept in motion on the bottom of a tank, so that it can trickle in free fall through an opening made in the bottom of the tank. a container and opening into an inlet pipe of an injection nozzle which distributes by air stream the pulverulent material coming in mixture with a liquid.

En raison des variations de température et d'hygrométrie, ce procédé ne peut pas garantir un fonctionnement très précis de la distribution qui demande une régularité constante dans les proportions produit-liquide.Due to variations in temperature and humidity, this process cannot guarantee very precise operation of the distribution which requires constant regularity in product-liquid proportions.

On utilise également des dispositifs ou des machines faisant appel à un tourbillon produit par un écoulement tangentiel, par exemple, dans un cyclone avec évacuation inférieure. A condition de maintenir le tourbillon constant, un cyclone constitue un dispositif approprié, sous consommation élevée d'énergie pour introduire des matières en poudre dans un liquide. Il existe toutefois le risque que des gaz émanant du tourbillon soient également aspirés dans le liquide. Le gaz parvient alors dans les éléments d'acheminement situés en aval et nuit à l'uniformité du débit. Il peut même interrompre l'acheminement. La formation constante du tourbillon n'est alors plus garantie d'une part, et d'autre part, cela entraîne le dépôt de parties lourdes de matières solides, ce qui a pour effet de provoquer la formation de ponts et le colmatage progressif des tuyauteries.Devices or machines are also used which use a vortex produced by a tangential flow, for example, in a cyclone with lower discharge. Provided that the vortex is kept constant, a cyclone constitutes an appropriate device, under high energy consumption, for introducing powdered materials into a liquid. There is however the risk that gases from the vortex are also drawn into the liquid. The gas then reaches the conveying elements located downstream and harms the uniformity of the flow. It can even interrupt the routing. The constant formation of the vortex is then no longer guaranteed on the one hand, and on the other hand, this leads to the deposition of heavy parts of solid matter, which has the effect of causing the formation of bridges and the progressive clogging of the pipes. .

Le procédé de distribution et la machine qui s'y rapporte,objet de la présente invention, évitent les inconvénients mentionnés ci-dessus et présentent en plus des avantages évidents au niveau de la fiabilité, de la précision de distribution et de la rapidité de modification des différentes opérations de lavage, en particulier entre l'opération utilisant le savon et le rinçage utilisant uniquement une eau adoucie.The dispensing method and the machine relating thereto, which is the subject of the present invention, avoid the drawbacks mentioned above and have, in addition, obvious advantages in terms of reliability, dispensing precision and speed of modification. different washing operations, in particular between the operation using soap and rinsing using only softened water.

La permutation de ces deux opérations étant pratiquement instantanée en raison du faible volume eau-savon se trouvant dans un récipient mélangeur constitué d'un entonnoir.The permutation of these two operations being practically instantaneous due to the small volume of water-soap found in a mixing container constituted by a funnel.

Le procédé de distribution, relatif à l'invention, est caractérisé en ce que l'on conditionne dans un distributeur un produit qui est ensuite introduit dans un volume de transition dans lequel on ajoute un fluide formant un mélange qui est aspiré par effet venturi dans une conduite d'alimentation principale qui véhicule, par l'intermédiaire d' une pompe, le mélange dans une lance de lavage.The dispensing process, relating to the invention, is characterized in that a product is packaged in a dispenser which is then introduced into a transition volume in which a fluid forming a mixture is added which is sucked in by venturi effect in a main supply line which conveys, via a pump, the mixture in a washing lance.

Une machine pour la mise en oeuvre du procédé décrit ci-dessus est également prévue et se caractérise par un distributeur de stockage de poudre relié à un volume de transition constitué par un entonnoir mélangeur pourvu d'une conduite d'entrée d'eau et d'une ouverture de sortie du mélange qui alimente une conduite principale composée d'un dispositif venturi, de vannes de distribution, reliées à une pompe volumétrique alimentant une lance de lavage mobile.A machine for implementing the method described above is also provided and is characterized by a powder storage distributor connected to a transition volume constituted by a mixing funnel provided with a water inlet pipe and d '' a mixture outlet opening which feeds a main pipe composed of a venturi device, distribution valves, connected to a positive displacement pump supplying a mobile washing lance.

La manière dont l'invention peut être réalisée et les avantages qui en découlent ressortiront mieux des exemples de réalisation qui suivent, donnés à titre indicatif et non limitatif à l'appui des figures annexées, dans lesquelles :

La fig. 1
représente une coupe schématique en élévation d'une machine pour la mise en oeuvre du procédé.
La fig. 2
représente un schéma de principe du fonctionnement de l'ensemble de la machine.
The manner in which the invention can be implemented and the advantages which ensue therefrom will emerge more clearly from the following exemplary embodiments, given by way of nonlimiting illustration in support of the appended figures, in which:
Fig. 1
shows a schematic sectional elevation of a machine for implementing the method.
Fig. 2
shows a block diagram of the operation of the whole machine.

En référence avec la fig. 2, le procédé consiste à distribuer une poudre 1 contenue dans un réservoir 2,au travers d'une ouverture pratiquée dans le fond du réservoir 2. La poudre 1 tombant dans un volume de transition 13 se rapportant à un entonnoir mélangeur recevant un liquide formant un mélange 14. Le mélange 14 (eau + poudre) passe au travers d'un clapet de retenue 34 par aspiration selon effet venturi, pour se retrouver dans une conduite principale d'eau 27 qui est reliée à des vannes de distribution 42 et à une pompe volumétrique 43 alimentant une lance de lavage non représentée.With reference to fig. 2, the method consists in dispensing a powder 1 contained in a reservoir 2, through an opening made in the bottom of the reservoir 2. The powder 1 falling into a transition volume 13 relating to a mixing funnel receiving a liquid forming a mixture 14. The mixture 14 (water + powder) passes through a check valve 34 by suction according to the venturi effect, to end up in a main water pipe 27 which is connected to distribution valves 42 and to a positive displacement pump 43 supplying a washing lance not shown.

La machine pour la mise en oeuvre du procédé, en référence à la fig. 1, comprend un réservoir 2 recevant un moteur d'entraînement 3 pourvu d'un accouplement débrayage 4 de sécurité monté sur un axe central 5 qui comprend des peignes mélangeurs 6 tournants, brassant une poudre 1 (fig.2) de manière à créer un mouvement tourbillonaire permanent évitant la solidification de la poudre 1 en relation avec le degré hygrométrique de l'air ambiant. Un émotteur 10 est fixé à l'extrémité inférieur de l'arbre central 5 qui reçoit un couteau racleur 11 faisant passer au travers d'une ouverture 12 une quantité déterminée de poudre 1 tombant dans un entonnoir 13 mélangeur.The machine for implementing the method, with reference to FIG. 1, comprises a reservoir 2 receiving a drive motor 3 provided with a disengaging coupling 4 safety mounted on a central axis 5 which includes mixing combs 6 rotating, brewing a powder 1 (fig.2) so as to create a permanent vortex movement avoiding solidification of the powder 1 in relation to the humidity of the ambient air. A lump breaker 10 is fixed to the lower end of the central shaft 5 which receives a scraper knife 11 passing through a opening 12 a determined quantity of powder 1 falling into a funnel 13 mixer.

L'arbre 5 est usiné, à l'une de ses extrémités 15, par une portée 16 venant se positionner dans un roulement à bille 17 radial, permettant l'absorbtion de la charge axiale de l'ensemble du mécanisme tournant. Sur l'arbre central 5 on a prévu un positionneur 20 qui déclenche un capteur de proximité 21 permettant de stopper le couteau racleur 11 directement sur l'ouverture 12 de manière à obturer les distribution de poudre 1 dans l'entonnoir 13.The shaft 5 is machined, at one of its ends 15, by a bearing 16 which is positioned in a radial ball bearing 17, allowing the absorption of the axial load of the whole of the rotating mechanism. A central positioner 20 is provided on the central shaft 5 which triggers a proximity sensor 21 making it possible to stop the scraper knife 11 directly on the opening 12 so as to close off the powder distribution 1 in the funnel 13.

Comme le montre explicitement la fig. 1, l'entonnoir 13 est agencé d'une conduite d'entrée d'eau 25 qui est commandée par une électro vanne 26 branchée sur la conduite principale 27 d'eau chaude (fig.2). Le volume du mélange ainsi obtenu (eau-poudre) est contrôlé en permanence par un détecteur de niveau 18 qui régularise par des moyens connus l'entrée d'eau 25 en fonction de l'entrée de la poudre 1.As shown in fig. 1, the funnel 13 is arranged with a water inlet pipe 25 which is controlled by a solenoid valve 26 connected to the main hot water pipe 27 (fig.2). The volume of the mixture thus obtained (water-powder) is constantly monitored by a level detector 18 which regulates by known means the water inlet 25 according to the powder inlet 1.

Un filtre 30 permet de faire un auto-contrôle de la pureté mécanique du mélange eau-poudre.A filter 30 allows self-checking of the mechanical purity of the water-powder mixture.

L'entonnoir 13 mélangeur est monté sur un support 32 qui est pourvu d'une conduite de sortie 33 passant au travers d'un clapet de retenue 34 qui se ferme automatiquement lorsque la pression diminue dans le circuit secondaire d'alimentation 35. Pour faire fonctionner le circuit 35 il a été prévu un dispositif venturi 38 qui provoque une aspiration du mélange eau-poudre se trouvant dans l'entonnoir 13.The mixer funnel 13 is mounted on a support 32 which is provided with an outlet line 33 passing through a check valve 34 which closes automatically when the pressure decreases in the secondary supply circuit 35. To do this to operate the circuit 35, a venturi device 38 has been provided which causes the water-powder mixture in the funnel 13 to be suctioned.

Une conduite bypass calibrée 40 évite la cavitation du liquide respectivement provoque une régularité de pression entre l'entrée et la sortie du dispositif venturi 38.A calibrated bypass pipe 40 avoids cavitation of the liquid respectively, causes a regularity of pressure between the inlet and the outlet of the venturi device 38.

Le sens de l'écoulement du fluide étant clairement indiqué par les flèches noires (fig.2).The direction of the fluid flow being clearly indicated by the black arrows (fig. 2).

La conduite principale 27 est encore reliée à des vannes de distribution 42 qui sont branchées sur une pompe volumétrique 43 alimentant la lance de lavage (non représentée).The main line 27 is also connected to distribution valves 42 which are connected to a positive displacement pump 43 supplying the washing lance (not shown).

Par des moyens connus et par conséquent non décrits, ayant trait au dispositif de commande, il est possible de réaliser un dosage et une distribution de savon liquide d'une très grande précision au fur et à mesure des besoins en lavage. On évite également les pertes de chauffage qui sont dues dans les installations existentes à un trop grand volume d'eau mélangée à disposition.By known means and therefore not described, relating to the control device, it is possible to carry out a metering and distribution of liquid soap of a very large precision as and when required for washing. It also avoids the heating losses which are due in existing installations to too large a volume of mixed water available.

La machine, objet de la présente invention peut être dotée dans une variante d'exécution d'une électro vanne à la place du clapet de retenue 34, d'une vanne modulante à la place du bypass 40 et d'un dispositif d'auto-réglage de la section d'aspiration du venturi 38 dans le cas de viscosité variable selon des opérations de lavage plus complexes.The machine, object of the present invention can be provided in a variant of an electro-valve in place of the check valve 34, a modulating valve in place of the bypass 40 and an auto device. -adjusting the suction section of the venturi 38 in the case of variable viscosity according to more complex washing operations.

La commande des différents appareils qui constituent la machine peut être réalisée au moyen d'un programmateur asservi par un microprocesseur.The control of the various apparatuses which constitute the machine can be carried out by means of a programmer controlled by a microprocessor.

Sur la conduite principale qui alimente la lance de lavage, il est possible d'adjoindre des appareils de contrôle ou de dosage de produits de polissage ou des produits neutralisants.On the main line supplying the washing lance, it is possible to add control or metering devices for polishing agents or neutralizing agents.
