Description

La présente invention concerne un dispositif permettant de diviser un courant de liquide primaire en plusieurs courants secondaires dont les débits sont des fractions prédéterminées du débit du courant primaire.The present invention relates to a device making it possible to divide a stream of primary liquid into several secondary streams whose flow rates are predetermined fractions of the flow rate of the primary stream.

Dans de nombreuses installations industrielles, on est amené à diviser un courant de liquide en plusieurs courants partiels dont les débits doivent être égaux à des pourcentages prédéterminés du débit total. Cela est notamment le cas en sucrerie, dans l'alimentation en liqueur des différents compartiments d'une cuite continue. On utilise généralement dans ce cas une série de tuyaux branchés sur une tuyauterie principale, chaque tuyau étant équipé d'une vanne de réglage. Mais l'expérience montre que pour un réglage donné des vannes permettant d'obtenir, pour un débit donné, une répartition prédéterminée du débit total dans les différents tuyaux, une variation du débit total provoque une modification de la répartition, et qu'il est nécessaire d'effectuer un nouveau réglage de toutes les vannes pour obtenir la répartition désirée. Lorsque le débit total est réglé automatiquement, il faut donc prévoir un système de régulation complexe agissant sur les différentes vannes de réglage, pour maintenir les rapports désirés entre le débit total et les débits de courants partiels.In many industrial installations, it is necessary to divide a stream of liquid into several partial streams, the flow rates of which must be equal to predetermined percentages of the total flow rate. This is particularly the case in candy, in the supply of liquor to the various compartments of continuous baking. In this case, a series of pipes connected to a main pipe are generally used, each pipe being fitted with an adjustment valve. However, experience shows that for a given adjustment of the valves making it possible to obtain, for a given flow, a predetermined distribution of the total flow in the different pipes, a variation in the total flow causes a modification of the distribution, and that it is it is necessary to carry out a new adjustment of all the valves to obtain the desired distribution. When the total flow is automatically regulated, it is therefore necessary to provide a complex regulation system acting on the various control valves, to maintain the desired ratios between the total flow and the partial current flows.

L'invention a pour but de proposer un dispositif répartiteur permettant de diviser un courant de liquide primaire en plusieurs courants secondaires, et de maintenir les débits du courant primaire et des courants secondaires dans des rapports prédéterminés, lorsque le débit du courant primaire varie.The object of the invention is to propose a distributor device making it possible to divide a stream of primary liquid into several secondary streams, and to maintain the flow rates of the primary stream and the secondary streams in predetermined ratios, when the flow rate of the primary stream varies.

Elle a plus précisément pour objet un dispositif pour diviser un courant de liquide primaire en plusieurs courants secondaires dont les débits sont des fractions prédéterminées du débit du courant primaire, caractérisé en ce qu'il comporte une chambre principale recevant le courant de liquide primaire, et plusieurs chambres secondaires attenantes à la chambre principale, dont le nombre est égal à celui des courants secondaires, en ce que chaque chambre secondaire est séparée de la chambre principale par une cloison dans laquelle est découpée au moins une ouverture verticalement allongée et dont la largeur augmente progressivement de bas en haut, en ce que le bas de toutes les ouvertures se trouve au même niveau, toutes les ouvertures ayant la même forme générale et leur largeur, à un niveau donné, étant d'autant plus grande que la fraction du débit total qui les traverse est plus importante, et en ce que chaque chambre secondaire est munie d'une sortie pour un courant secondaire.More specifically, it relates to a device for dividing a stream of primary liquid into several secondary streams whose flow rates are predetermined fractions of the flow rate of the primary stream, characterized in that it comprises a main chamber receiving the stream of primary liquid, and several secondary chambers adjoining the main chamber, the number of which is equal to that of the secondary currents, in that each secondary chamber is separated from the main chamber by a partition in which is cut at least one vertically elongated opening and whose width increases gradually from bottom to top, in that the bottom of all the openings is at the same level, all the openings having the same general shape and their width, at a given level, being all the greater as the fraction of the total flow which passes through them is more important, and in that each secondary chamber is provided with an outlet for a secondary current.

Les cloisons séparant les chambres secondaires de la chambre principale sont amovibles, afin de pouvoir être remplacées par d'autres cloisons ayant des ouvertures différentes, et modifier ainsi la répartition du courant primaire entre les différentes sorties des chambres secondaires.The partitions separating the secondary chambers from the main chamber are removable, so that they can be replaced by other partitions having different openings, and thus modify the distribution of the primary current between the different outputs of the secondary chambers.

L'une au moins des autres cloisons de remplacement est alors une cloison pleine afin de réduire le nombre des courants secondaires.At least one of the other replacement partitions is then a solid partition in order to reduce the number of secondary currents.

Les cloisons séparant les chambres secondaires de la chambre principale sont, au moins en partie, munies de moyens de réglage de la section utile de leurs ouvertures respectives.The partitions separating the secondary chambers from the main chamber are, at least in part, provided with means for adjusting the useful section of their respective openings.

Chaque moyen de réglage comprend avantageusement un volet rotatif apte à obturer partiellement l'ouverture coopérante. Le dispositif est avantageusement constitué par un récipient divisé par des cloisons, en une chambre principale et plusieurs chambres secondaires.Each adjustment means advantageously comprises a rotary shutter capable of partially closing the cooperating opening. The device is advantageously constituted by a container divided by partitions, into a main chamber and several secondary chambers.

Les ouvertures des cloisons sont constituées par des échancrures en forme de V.The partition openings are formed by V-shaped notches.

Le récipient est de préférence cylindrique, à axe horizontal, et comporte dans sa partie inférieure une entrée située sensiblement à mi-longueur et une ou plusieurs sorties à chacune de ses extrémités. Les deux cloisons transversales dans lesquelles sont découpées les échancrures en V sont alors disposées entre l'entrée et les deux sorties.The container is preferably cylindrical, with a horizontal axis, and has in its lower part an inlet situated substantially at mid-length and one or more outlets at each of its ends. The two transverse partitions in which the V-shaped notches are cut are then placed between the inlet and the two outlets.

Dans le cas où une seule ouverture est prévue à chaque extrémité et une seule échancrure est prévue dans chaque cloison, les angles au sommet de ces échancrures sont choisis en fonction de la répartition désirée du débit d'entrée entre les deux sorties.In the case where a single opening is provided at each end and a single notch is provided in each partition, the angles at the top of these notches are chosen according to the desired distribution of the inlet flow between the two outlets.

Dans le cas où plusieurs sorties sont prévues à une ou aux deux extrémités, et où la ou les cloisons correspondantes comportent autant d'échancrures qu'il y a de sorties, des cloisons longitudinales sont prévues pour former entre la paroi d'extrémité du récipient et la cloison transversale adjacente, autant de chambres secondaires qu'il y a de sorties, chaque chambre secondaire comprenant une sortie et communiquant avec la chambre principale par une échancrure.In the case where several outlets are provided at one or both ends, and where the corresponding partition or partitions have as many indentations as there are outlets, longitudinal partitions are provided to form between the end wall of the container and the adjacent transverse partition, as many secondary chambers as there are outlets, each secondary chamber comprising an outlet and communicating with the main chamber by a notch.

Des moyens sont prévus pour maintenir la pression dans le récipient à une valeur prédéterminée.Means are provided for maintaining the pressure in the container at a predetermined value.

Des toles planes verticales sont avantageusement disposées dans la chambre principale, parallèlement à l'axe du récipient, et espacées transversalement les unes des autres, en vue de maintenir plane la surface du liquide. L'invention sera mieux comprise en se référant à la description qui suit, faite en regard des dessins annexés, concernant une forme particulière de réalisation donnée à titre d'exemple non limitatif.

  • La figure 2 en est une coupe suivant la ligne A-A de la figure 1.
  • La figure 3 en est une coupe suivant la ligne B-B de la .figure 1.
  • La figure 4 en est une coupe suivant la ligne C-C de la figure 1.
Vertical flat sheets are advantageously arranged in the main chamber, parallel to the axis of the container, and spaced transversely from each other, in order to keep the surface of the liquid flat. The invention will be better understood by referring to the description which follows, given with reference to the appended drawings, concerning a particular embodiment given by way of nonlimiting example.
  • Figure 1 is an elevational sectional view of the device.
  • Figure 2 is a section along line AA of Figure 1.
  • Figure 3 is a section along line BB of .figure 1.
  • FIG. 4 is a section along the line CC of FIG. 1.

Sur les figures, le repère 1 désigne globalement un récipient cylindrique à axe horizontal X-X présentant, dans sa partie centrale, une chambre principale 2 alimentée par un courant de liquide à sa partie inférieure grâce à la tubulure 3 située sensiblement à mi-longueur du récipient 1. A l'intérieur de la chambre 2 sont aménagées des toles planes verticales, telles que 4, dont la fonction consiste à maintenir plane la surface du liquide compte tenu des conditions d'écoulement dont il sera parlé plus loin. Ces toles, au nombre de quatre dans l'exemple représenté sont transversalement espacées et disposées parallèlement à l'axe X-X du récipient 1. Elles sont rendues solidaires des parois de ce dernier au moyen de tiges traversantes, telles que 5.In the figures, the reference numeral 1 generally designates a cylindrical container with a horizontal axis XX having, in its central part, a main chamber 2 supplied by a stream of liquid at its lower part thanks to the tube 3 located substantially at the mid-length of the container. 1. Inside the chamber 2 are arranged vertical flat sheets, such as 4, the function of which is to keep the surface of the liquid flat taking into account the flow conditions which will be discussed below. These sheets, four in number in the example shown, are transversely spaced and arranged parallel to the axis X-X of the container 1. They are made integral with the walls of the latter by means of through rods, such as 5.

Sur la partie droite de la figure 1, est représentée une première chambre secondaire 6 attenante à la chambre 2 dont elle est séparée par une cloison transversale 7. Les chambres 2 et 6 communiquent entre elles par une échancrure 8 à section en V pratiquée dans la cloison 7. Le liquide admis dans la chambre 6 à travers l'échancrure 8 sort de ladite chambre par une tubulure 9.On the right-hand side of FIG. 1, there is shown a first secondary chamber 6 adjoining the chamber 2 from which it is separated by a transverse partition 7. The chambers 2 and 6 communicate with each other by a notch 8 with a V section practiced in the partition 7. The liquid admitted into the chamber 6 through the notch 8 leaves said chamber through a tube 9.

L'extrémité du récipient 1 est munie d'une vitre de regard 10 qui permet d'observer l'écoulement à l'intérieur de la chambre 6.The end of the container 1 is provided with a viewing window 10 which makes it possible to observe the flow inside the chamber 6.

Sur la partie gauche de la figure 1, sont représentées deux autres chambres secondaires 11' et 11" attenantes à la chambre 2 dont elles sont séparées par une cloison transversale 12. Les chambres 11' et 11" sont séparées l'une de l'autre par une cloison longitudinale 13. La chambre principale 2 communique avec les chambres secondaires 11' et 11" par des échancrures, respectivement 14' et 14", à section en V pratiquées dans la cloison 12, symétriquement de part et d'autre de la cloison 13. Le liquide admis dans les chambres 11' et 11" à travers les échancrures 14' et 14", sort desdites chambres par deux tubulures, respectivement 15' et 15". L'extrémité du récipient 1 est munie d'une vitre de regard 16 qui permet d'observer l'écoulement à l'intérieur des chambres 11' et 11" d'une manière analogue à la disposition décrite en référence à l'extrémité opposée.On the left-hand side of FIG. 1, two other secondary chambers 11 'and 11 "are shown adjoining the chamber 2 from which they are separated by a transverse partition 12. The chambers 11' and 11" are separated from one other by a longitudinal partition 13. The main chamber 2 communicates with the secondary chambers 11 ′ and 11 ″ by notches, respectively 14 ′ and 14 ″, with a V section formed in the partition 12, symmetrically on either side of the partition 13. The liquid admitted into the chambers 11 'and 11 "through the notches 14' and 14", leaves said chambers by two pipes, respectively 15 'and 15 ". The end of the container 1 is provided with a sight glass 16 which makes it possible to observe the flow inside the chambers 11 'and 11 "in a manner analogous to the arrangement described with reference to the opposite end.

La cloison 7 peut être munie d'un volet 17 en forme de secteur circulaire, apte à pivoter autour d'un axe situé à la pointe du V formé par l'échancrure 8 de manière à obturer plus ou moins cette dernière. La cloison 12 peut être munie de volets 18' et 18" de même forme que le précédent, aptes à pivoter autour d'axes situés à la pointe du V formé par les échancrures 14' et 14", respectivement, de manière à obturer plus ou moins ces échancrures. Le déplacement de chaque volet peut être effectué par un moyen quelconque, par exemple une vis, commandable de l'extérieur. Cette disposition est particulièrement avantageuse pour modifier la répartition du débit de sortie entre les tubulures 9, 15' et 15". Il est nécessaire de placer la pointe des échancrures 8, 14' et 14" au même niveau. A un niveau donné, la largeur des dites échancrures est d'autant plus grande que la fraction du débit total qui les traverse doit être plus 'important.The partition 7 can be provided with a flap 17 in the form of a circular sector, able to pivot around an axis located at the tip of the V formed by the notch 8 so as to more or less close the latter. The partition 12 can be fitted with flaps 18 ′ and 18 ″ of the same shape as the previous one, capable of pivoting around axes located at the tip of the V formed by the notches 14 ′ and 14 ″, respectively, so as to seal more or less these notches. The displacement of each flap can be carried out by any means, for example a screw, controllable from the outside. This arrangement is particularly advantageous for modifying the distribution of the outlet flow between the pipes 9, 15 'and 15 ". It is necessary to place the point of the notches 8, 14' and 14" at the same level. At a given level, the width of said notches is all the greater the greater the fraction of the total flow which passes through them.

Bien que l'invention ait été décrite en référence à une forme particulière de réalisation, il va de soi qu'elle n'y est en rien limitée et que des modifications peuvent lui être apportées sans sortir de son domaine.Although the invention has been described with reference to a particular embodiment, it goes without saying that it is in no way limited thereto and that modifications can be made to it without departing from its field.

Le nombre des chambres secondaires pourra être différent de trois.The number of secondary bedrooms may be different from three.

Si on ne souhaite pas équiper les cloisons de volets tels que 17, 18' ou 18", on pourra prévoir du côté de chaque chambre secondaire, une cloison transversale constituée de plusieurs éléments amovibles, chaque cloison élémentaire comportant une seule échancrure. On peut_ainsi facilement remplacer une cloison élémentaire par une autre ayant une échancrure d'angle différent. On peut aussi prévoir au moins une cloison élémentaire pleine dans la mesure où l'on désire limiter le nombre des sorties. On parvient ainsi à régler la répartition du débit de sortie à la demande.If one does not wish to equip the partitions with shutters such as 17, 18 ′ or 18 ", one can provide on the side of each secondary chamber, a transverse partition made up of several removable elements, each elementary partition comprising a single indentation. replace an elementary partition with another having a notch with a different angle. It is also possible to provide at least one full elementary partition if it is desired to limit the number of outlets. This thus manages to regulate the distribution of the outlet flow on demand.

On pourra prévoir une configuration d'ensemble différente, le récipient, au lieu d'être cylindrique, étant de forme parallépipédique, ouvert à sa partie supérieure. L'entrée du liquide peut alors être disposée au-dessus du récipient. Dans ce cas, les cloisons n'atteignent pas nécessairement le niveau du bord supérieur du récipient. Les cloisons peuvent alors être disposées le long d'un même côté ou suivant deux côtés opposés.We can provide a different overall configuration, the container, instead of being cylindrical, being of rectangular shape, open at its upper part. The liquid inlet can then be arranged above the container. In this case, the partitions do not necessarily reach the level of the upper edge of the container. The partitions can then be arranged along the same side or along two opposite sides.

On pourra aussi prévoir une chambre principale de forme cylindrique, à axe vertical, et des chambres secondaires périphériques disposées radialement autour de la chambre principale. La paroi de cette dernière est alors munie d'échancrures, à raison d'une échancrure par chambre secondaire attenante. L'alimentation en liquide peut être effectuée par le haut ou par le bas du cylindre et les sorties sont disposées radialement vers l'extérieur, c'est-à-dire du côté opposé à la chambre principale. On pourra éventuellement remplacer les échancrures par des ouvertures ménagées dans les parois des cloisons. Le profil de ces ouvertures devra être tel qu'il présente les mêmes particularités que les échancrures : forme verticalement allongée, largeur croissante de bas en haut, bas de toutes les ouvertures au même niveau.It is also possible to provide a main chamber of cylindrical shape, with a vertical axis, and peripheral secondary chambers arranged radially around the main chamber. The wall of the latter is then provided with notches, at the rate of a notch by adjoining secondary chamber. The liquid supply can be carried out from the top or from the bottom of the cylinder and the outlets are arranged radially outwards, that is to say on the side opposite to the main chamber. We can possibly replace the notches with openings in the walls of the partitions. The profile of these openings must be such that it has the same characteristics as the notches: vertically elongated shape, increasing width from bottom to top, bottom of all openings at the same level.

Dans le cas d'un récipient fermé, des moyens peuvent être avantageusement prévus pour maintenir la pression dans le récipient à une valeur constante prédéterminée.In the case of a closed container, means can advantageously be provided to maintain the pressure in the container at a predetermined constant value.

On pourra, bien entendu, remplacer l'un quelconque des moyens décrits, par un moyen techniquement équivalent.We can, of course, replace any of the means described, by a technically equivalent means.

L'invention couvre donc, outre l'exemple représenté ses différentes variantes d'exécution possibles, dans les limites définies par les revendications.The invention therefore covers, in addition to the example shown, its various possible alternative embodiments, within the limits defined by the claims.
