Abstract

The mixer is new. The liquid and aggregated substrate are contained in cylindrical tank with vertical axis XX', which is also a rotation axis of the tubular column (1) of the mixer. (1) is provided, in its upper part, with entry port (2) for pressurized liquid, which passes through a turning joint (3). The column (1) has a jet (4) provided at its lower part and inclined at an angle (a) to the vertical axis. The angle oscillates between two determined values and is controlled by a computer control system (17). The combination of the rotating and oscillating action creates a programmed path of the jet impact over the substrate, situated underneath. The control system is programmed in such way as to ensure that jet impact results in the creation of spiral patterns on the surface of the substrate. The system receives a signal of the substrate level in the tank and imposes, by means of a control jack (13), the angular speeds and jet (4) angle (a) variation amplitudes in such way as to ensure that the spirals cover practically whole surface of the substrate, at a constant pitch (the system is preferably provided with the means allowing to choose the desired spiral pitch). The system may be also provided with exterior command allowing to adapt the maximum diameter of spirals to that of the substrate. Radar or ultrasonic sensor of the substrate level may be used to send direct signal to control system (17).

Description

La présente invention concerne un mélangeur<B>à</B> jet dirigé pour désagrégation et mise en dispersion dans un liquide d'un substrat flottant<B>à</B> sa surface. The present invention relates to a jet blender directed to disintegrate and disperse liquid in a floating substrate <B> to </ B> its surface.

Lors de l'élaboration du moût de raisin destiné<B>à</B> la fabrication du vin rouge, on obtient après écrasement des raisins un liquide au-dessus duquel flotte un substrat. Ce dernier est constitué principalement par les grains de raisin partiellement écrasés qui se recollent entre eux et donnent<B>à</B> ce substrat une texture relativement compacte ayant constamment tendance<B>à</B> se reformer après désagrégation.<B>Il</B> est essentiel, pour l'obtention des qualités particulieres <B>à</B> un cru, que les principes actifs contenus dans ce substrat soient transférés au liquide sous-jacent avec un maximum d'efficacité. Un mélangeur est nécessaire pour désagréger ce substrat et disperser le maximum de ses principes actifs dans le liquide. When making the grape must intended for the manufacture of red wine, after crushing the grapes, a liquid is obtained above which a substrate floats. The latter consists mainly of partially crushed grapes that glue together and give <B> to this substrate a relatively compact texture that has a constant tendency <B> to </ B> to reform after disintegration. B> It is essential, for obtaining the special qualities <B> to </ B> a vintage, that the active principles contained in this substrate are transferred to the underlying liquid with a maximum of efficiency. A mixer is necessary to disintegrate this substrate and disperse the maximum of its active ingredients in the liquid.

connaît un mélangeur qui met en #uvre au niveau du substrat des fléaux horizontaux, verticaux ou inclinés actionnés par des moyens mécaniques ou hydrauliques qui brisent ce substrat. Ce dernier se désagrège au voisinage immédiat des fléaux mais la difficulté d'élargir leur action sur toute surface du substrat handicape leur efficacité. A mixer is known which uses at the level of the substrate horizontal, vertical or inclined flails actuated by mechanical or hydraulic means which break this substrate. The latter disintegrates in the immediate vicinity of the plagues but the difficulty of widening their action on any surface of the substrate handicaps their effectiveness.

Un autre moyen consiste<B>à</B> agir depuis le sommet la cuve avec un jet alimenté avec la partie liquide sous pression, orienté manuellement en divers endroits sur le substrat. Cette pratique est pénible pour l'opérateur qui doit fournir effort physique dans un environnement comportant odeurs et brouillards désagréables. Les mouvements aléatoires imprimés au jet associés<B>'</B> une visibilité souvent mauvaise ne permettent pas d'atteindre régulièrement toute la surface du substrat et de bénéficier de toute l'efficacité du procédé. Another way is to act from the top of the tank with a jet fed with the pressurized liquid part, manually oriented in various places on the substrate. This practice is painful for the operator who must provide physical effort in an environment with unpleasant odors and mists. The random movements printed with the associated jet <B> '</ B> a visibility often bad do not make it possible to reach regularly the whole surface of the substrate and to benefit from all the effectiveness of the process.

Les moyens employés dans les opérations ci-dessus n'agissent pas systématiquement sur toute la surface du substrat et certaines parties sont plus ou moins épargnées ayant pour conséquence delà d'un certain temps de mise en #uvre l'effet de dispersion devient très faible par épuisement des parties du substrat concernées alors que parties riches sont hors d'atteinte. The means used in the above operations do not act systematically over the entire surface of the substrate and some parts are more or less spared having the effect of a certain time of implementation the dispersion effect becomes very low by exhaustion of the parts of the substrate concerned while rich parts are out of reach.

La présente invention a donc pour objet un mélangeur a jet dirigé pour désagrégation et mise en dispersion dans un liquide d'un substrat flottant<B>à</B> sa surface donnant une efficacité accrue, des conditions de travail améliorées et un traitement homogène du substrat caractérisé par le fait qu'il est mécanisé et qu'il est imposé,<B>à</B> l'impact du jet sur le substrat pour le désagréger, un parcours programmé et régulier sur toute la surface de ce substrat. Ce mélangeur est placé au sommet d'une cuve cylindrique verticale et en son centre, un signal de niveau est émis par le capteur de mesure de niveau du produit dans la cuve. The subject of the present invention is therefore a directed jet mixer for disintegrating and dispersing in a liquid of a floating substrate <B> at </ B> its surface giving increased efficiency, improved working conditions and homogeneous treatment. of the substrate characterized by the fact that it is mechanized and that it is imposed, <B> to </ B> the impact of the jet on the substrate to disintegrate it, a programmed and regular path over the entire surface of this substrate . This mixer is placed at the top of a vertical cylindrical tank and at its center, a level signal is emitted by the product level sensor in the tank.

<B>Il</B> comprend selon une autre caractéristique, une colonne tubulaire verticale supportée par un châssis entraînée en rotation sur axe vertical par un moteur. Cette colonne tubulaire est alimentée en liquide procédé sous pression<B>à</B> sa partie supérieure<B>à</B> travers un joint tournant. Elle débite<B>à</B> la partie inférieure dans un jet articulé sur un axe horizontal façon étanche sur cette colonne tubulaire, tournant avec elle et orientable dans un de ses plans verticaux, de façon continue entre la direction verticale dans le prolongement la colonne tubulaire et une direction variable pouvant atteindre sensiblement l'horizontale. Cette orientation est commandée par un vérin lui-même asservi<B>à</B> un système informatique installés châssis. Un système de butee et manchon coulissant sur la colonne tubulaire transmet le mouvement du vérin non tournant au jet tournant avec la colonne tubulaire. Le système informatique réagit<B>à</B> un signal de niveau. <B> It </ B> comprises according to another feature, a vertical tubular column supported by a frame driven in rotation on a vertical axis by a motor. This tubular column is supplied with pressurized process liquid <B> at </ B> its upper part <B> to </ B> through a rotating joint. It discharges <B> to </ B> the lower part in a jet articulated on a horizontal axis sealingly on this tubular column, rotating with it and orientable in one of its vertical planes, continuously between the vertical direction in the extension the tubular column and a variable direction that can reach substantially horizontal. This orientation is controlled by a jack itself enslaved to a computer system installed chassis. A stop system and sleeve sliding on the tubular column transmits the movement of the non-rotating cylinder to the rotating jet with the tubular column. The computer system responds <B> to a level signal.

L'action combinée, de la rotation continue de la colonne tubulaire et du jet, et de l'oscillation de ce dernier, permet de faire décrire<B>à</B> l'impact du jet, un parcours la surface horizontale du substrat, programmé dans le système informatique. The combined action, the continuous rotation of the tubular column and the jet, and the oscillation of the latter, makes it possible to describe <B> to </ B> the impact of the jet, a course the horizontal surface of the substrate, programmed in the computer system.

Une application particulière est caractérisée par la mise place dans le système informatique d'un programme qui provoque une oscillation régulière suivant un angle aigu du jet entre la verticale et une valeur déterminée. L'impact du jet décrit alors des spirales successivement croissantes décroissantes sur la surface du substrat. Les caractéristiques dimensionnelles de ces spirales sont programmées dans le système informatique qui les corrige en fonction du niveau du substrat dans la cuve. Les spirales ont un pas suffisamment petit pour que l'effet mécanique de l'impact du jet désagrège toute la partie de substrat située dans l'espace d'un pas et un diametre final sensiblement égal au diamètre la cuve et du substrat. Ainsi<B>à</B> chaque cycle correspondant au parcours d'une spirale, toutes les parties du substrat ont subit une désagrégation et une partie des résidus entraînés par liquide du jet est dispersée de façon irreversible dans le liquide sous-jacent. Après un certain nombre de cycles toutes les parties du substrat ont été traitées de la même façon. A particular application is characterized by placing in the computer system a program that causes a regular oscillation at an acute angle of the jet between the vertical and a determined value. The impact of the jet then describes successively increasing decreasing spirals on the surface of the substrate. The dimensional characteristics of these spirals are programmed in the computer system which corrects them according to the level of the substrate in the tank. The spirals have a pitch small enough that the mechanical effect of the impact of the jet disintegrates the entire portion of the substrate located in the space of one step and a final diameter substantially equal to the diameter of the vessel and the substrate. Thus <B> at </ B> each cycle corresponding to the course of a spiral, all parts of the substrate have been disintegrated and a portion of the liquid-entrained residues of the jet is irreversibly dispersed in the underlying liquid. After a number of cycles all parts of the substrate were treated in the same way.
