Description

La présente invention est relative à une citerne du type comportant une enceinte définie par une enceinte extérieure cylindrique et une cloison radiale mobile montée coulissante dans l'enceinte et délimitant de part et d'autre, dans ladite enceinte, deux réservoirs de capacités variables.The present invention relates to a tank of the type comprising an enclosure defined by a cylindrical outer enclosure and a movable radial partition mounted sliding in the enclosure and delimiting on either side, in said enclosure, two reservoirs of variable capacities.

De telles citernes, detinées en particulier à être montées sur des véhicules, ont été réalisées par la société déposante en particulier pour des applications d'assainissement, notamment pour évacuer des déchets présents dans des ouvrages tels que des égouts et/ou pour vidanger des fosses.Such tanks, designed in particular to be mounted on vehicles, have been produced by the applicant company in particular for sanitation applications, in particular for discharging waste present in works such as sewers and / or for emptying pits .

L'un des réservoirs est destiné à la récupération des boues liquides provenant de l'ouvrage ou de la fosse en cours de nettoyage, l'autre réservoir constituant une réserve d'eau propre pouvant être injectée sous pression dans l'ouvrage ou la fosse à nettoyer ou éventuellement un compartiment destiné à recevoir également des boues.One of the reservoirs is intended for the recovery of liquid sludge from the structure or the pit being cleaned, the other reservoir constituting a reserve of clean water which can be injected under pressure into the structure or the pit to be cleaned or possibly a compartment intended to also receive sludge.

Il peut s'avérer dans la pratique nécessaire de disposer d'une citerne comportant trois réservoirs pour transporter des produits différents, et notamment dans l'application d'assainissement indiquée ci-dessus, comportant un résevoir contenant de l'eau propre, un réservoir destiné à la réception des boues et un troisième réservoir destiné à recueillir des eaux séparées des boues récupérées, par exemple par décantation en vue d'un recyclage.It may prove in practice necessary to have a tank comprising three tanks for transporting different products, and in particular in the sanitation application indicated above, comprising a tank containing clean water, a tank intended for the reception of sludge and a third tank intended to collect water separated from the recovered sludge, for example by decantation for recycling.

Il existe dans la pratique des citernes à trois réservoirs définis par deux cloisons fixes ou une cloison fixe et une cloison mobile à l'intérieur de l'enceinte.In practice, there are tanks with three tanks defined by two fixed partitions or a fixed partition and a movable partition inside the enclosure.

Cette solution ne permet que partiellement de faire varier les volumes des réservoirs en fonction de la quantité des produits à transporter et notamment ne permet pas d'éviter qu'un réservoir contenant un produit liquide se trouve partiellement rempli en cours de transport, ce qui a tendance à déséquilibrer le véhicule transportant la citerne par suite des accélérations subies par le liquide contenu dans le réservoir partiellement rempli.This solution only partially makes it possible to vary the volumes of the reservoirs as a function of the quantity of products to be transported and in particular does not prevent a reservoir containing a liquid product from being partially filled during transport, which has tendency to unbalance the vehicle transporting the tank as a result of the accelerations undergone by the liquid contained in the partially filled tank.

La citerne selon la présente invention se caractérise essentiellement par le fait que la cloison mobile est formée par deux parois solidarisées par une paroi cylindrique, ladite cloison mobile constituant dans l'enceinte un troisième réservoir de capacité fixe entre les deux réservoirs de capacités variables.The tank according to the present invention is essentially characterized by the fact that the movable partition is formed by two walls secured by a cylindrical wall, said movable partition constituting in the enclosure a third reservoir of fixed capacity between the two reservoirs of variable capacities.

La présente invention a également pour objet un véhicule routier essentiellement caractérisé par le fait qu'il comporte, sur une plate-forme; une citerne telle que définie ci-dessus.The present invention also relates to a road vehicle essentially characterized in that it comprises, on a platform; a tank as defined above.

Selon une caractéristique particulière de l'invention, il est prévu entre le troisième réservoir formé dans la cloison mobile et l'enveloppe de la citerne, des moyens de filtration, réalisés dans la paroi cylindrique de la cloison mobile ménagée entre ladite paroi cylindrique et l'enveloppe extérieure et/ou dans la sortie de l'espace annulaire.According to a particular characteristic of the invention, there is provided between the third reservoir formed in the movable partition and the shell of the tank, filtration means, produced in the cylindrical wall of the movable partition formed between said cylindrical wall and the outer casing and / or in the exit of the annular space.

Selon l'invention, des joints d'étanchéité sont avantageusement prévus entre la cloison mobile constituant le troisième réservoir et l'enveloppe définissant l'enceinte de la citerne. Il peut s'agir en particulier de joints en caoutchouc gonflables.According to the invention, seals are advantageously provided between the movable partition constituting the third tank and the envelope defining the enclosure of the tank. These may in particular be inflatable rubber seals.

Avantageusement, la citerne selon l'invention comporte également des organes, de préférence réglables, de positionnement et de butée pour la cloison mobile de manière à positionner celle-ci selon l'une de plusieurs positions à l'intérieur de l'enceinte.Advantageously, the tank according to the invention also comprises, preferably adjustable, positioning and abutment members for the movable partition so as to position the latter according to one of several positions inside the enclosure.

De manière en soi connue, il est prévu selon l'invention, des moyens pour déplacer la cloison mobile à l'intérieur de l'enceinte, ces moyens étant du type permettant d'appliquer une différence de pression de part et d'autre de la cloison mobile. Ces moyens peuvent par exemple comprendre une pompe à vide apte à réaliser une dépression d'un côté de la cloison mobile.In a manner known per se, means are provided according to the invention for moving the movable partition inside the enclosure, these means being of the type making it possible to apply a pressure difference on either side of the movable partition. These means may for example include a vacuum pump capable of producing a vacuum on one side of the movable partition.

D'autres avantages et caratéristiques de l'invention apparaîtront à la lecture de la description donnée ci-dessus d'un exemple de réalisation nullement limitatif illustré schématiquement sur le dessin annexé dans lequel :

  • - la figure unique est une vue schématique d'un exemple de réalisation de citerne selon l'invention.
Other advantages and characteristics of the invention will appear on reading the description given above of a nonlimiting exemplary embodiment illustrated diagrammatically in the appended drawing in which:
  • - The single figure is a schematic view of an exemplary embodiment of a tank according to the invention.

La citerne comporte une enveloppe cylindrique 1 fermée aux extrémités par des fonds 2 et 3, pouvant par exemple être réalisés de manière conventionnelle sous la forme de capots montés pivotants pour permettre un accès à l'intérieur de la citerne.The tank comprises a cylindrical casing 1 closed at the ends by bottoms 2 and 3, which can for example be produced in a conventional manner in the form of covers mounted to pivot to allow access to the interior of the tank.

Selon l'invention, il est prévu à l'intérieur de l'enveloppe une cloison mobile désignée globalement par 4 et comprenant, dans l'exemple illustré, deux cloisons radiales de forme bombée 5 et 6 solidarisées par une paroi cylindrique 7 disposée à distance de la paroi cylindrique de l'enveloppe 1 de la citerne en ménageant un espace annulaire 8.According to the invention, there is provided inside the envelope a movable partition generally designated by 4 and comprising, in the example illustrated, two radial partitions of convex shape 5 and 6 secured by a cylindrical wall 7 arranged at a distance of the cylindrical wall of the casing 1 of the tank, leaving an annular space 8.

La cloison 4 est montée coulissante à l'intérieur de l'enveloppe 1, des joints d'étanchéité gonflables 9 étant prévus entre la cloison mobile et l'enveloppe extérieure.The partition 4 is slidably mounted inside the enclosure 1, inflatable seals 9 being provided between the movable partition and the outer enclosure.

Les deux parois 5 et 6 définissent entre elles et la paroi cylindrique 7 un réservoir de capacité fixe 10.The two walls 5 and 6 define between them and the cylindrical wall 7 a reservoir of fixed capacity 10.

De part et d'autre de la cloison mobile 4, sont réalisés dans l'enceinte de la citerne, deux réservoirs 11 et 12 dont la capacité varie en fonction de la position de la cloison mobile.On either side of the movable partition 4, two reservoirs 11 and 12 are produced in the enclosure of the tank, the capacity of which varies according to the position of the movable partition.

Pour positionner et immobiliser la cloison mobile dans une pluralité de positions déterminées, il est prévu, d'une part des butées 13, et 14, la butée 13 pouvant être fixe, et la butée 14 amovible, et d'autre part des taquets escamotables manoeuvrables de l'extérieur 15, 16 et 17.To position and immobilize the movable partition in a plurality of determined positions, there are provided, on the one hand stops 13, and 14, the stop 13 which can be fixed, and the stop 14 removable, and on the other hand retractable cleats maneuverable from the outside 15, 16 and 17.

Ainsi, dans la position illustrée sur le dessin, la cloison mobile 4 est immobilisée par les taquets 15 et 16 qui sont en position sortie.Thus, in the position illustrated in the drawing, the movable partition 4 is immobilized by the lugs 15 and 16 which are in the extended position.

Si, par exemple, la cloison devait se trouver plus à gauche sur le dessin, elle serait positionnée et immobilisée par la butée 13 et le taquet 15, le taquet 16 pouvant alors être escamoté.If, for example, the partition were to be more to the left in the drawing, it would be positioned and immobilized by the stop 13 and the cleat 15, the cleat 16 can then be retracted.

La cloison dans l'exemple illustré peut également être maintenue entre les taquets 16 et 17 ou entre le taquet 17 et la butée 14.The partition in the example illustrated can also be maintained between the cleats 16 and 17 or between the cleat 17 and the stop 14.

Chacun des réservoirs 10, 11 et 12 est bien entendu muni de prises d'entrée et de sortie pour le raccordement de conduites permettant d'introduire et respectivement d'extraire du réservoir correspondant le produit devant y séjourner.Each of the tanks 10, 11 and 12 is of course provided with inlet and outlet sockets for the connection of conduits making it possible to introduce and respectively extract from the corresponding tank the product which is to remain there.

Pour le déplacement de la cloison mobile 4 à l'in- térieurde l'enceinte, on réalise un différentiel de pression de part et d'autre de cette cloison mobile.For the displacement of the movable partition 4 inside the enclosure, a pressure differential is produced on either side of this movable partition.

Dans l'exemple illustré, ce différentiel de pression est réalisé par dépression à l'aide d'une pompe à vide 18 pouvant être sélectivement raccordée en 19 au volume du réservoir 11 et en 20 au volume du réservoir 12.In the example illustrated, this pressure differential is produced by vacuum using a vacuum pump 18 which can be selectively connected at 19 to the volume of the reservoir 11 and at 20 to the volume of the reservoir 12.

Le circuit de vide est de type conventionnel et comporte un distributeur 21 sous forme de vanne à quatre voies, un silencieux 22, un filtre 23 et un réservoir de sécurité 24.The vacuum circuit is of the conventional type and includes a distributor 21 in the form of a four-way valve, a silencer 22, a filter 23 and a safety tank 24.

Un distributeur, sous forme de vanne à quatre voies 25 permet le raccordement sélectif du circuit de vide à l'un ou l'autre des volumes des réservoirs 11 et 12.A distributor, in the form of a four-way valve 25 allows the selective connection of the vacuum circuit to one or other of the volumes of the reservoirs 11 and 12.

Selon l'invention, il est avantageusement prévu des moyens de filtration (non représentés) au niveau du réservoir 10 défini dans la cloison mobile 4.According to the invention, there are advantageously provided filtration means (not shown) at the level of the reservoir 10 defined in the movable partition 4.

Ces moyens de filtration peuvent être de tout type approprié et montés sur la paroi cylindrique 7, dans l'espace annulaire 8 ou dans les moyens de mise en communication de l'espace annulaire 8 avec l'extérieur.These filtration means can be of any suitable type and mounted on the cylindrical wall 7, in the annular space 8 or in the means for bringing the annular space 8 into communication with the outside.

Bien que l'invention ait été décrite en liaison avec un mode de réalisation particulier, il est bien évident qu'elle n'y est nullement limitée et qu'on peut lui apporter différentes variantes et modifications sans pour auant sortir ni de son cadre ni de son esprit.Although the invention has been described in connection with a particular embodiment, it is obvious that it is in no way limited thereto and that it can be brought to it in different variants and modifications without departing from its scope or of his mind.
