Description

L'invention concerne une pompe péristaltique, et en particulier une pompe péristaltique à tuyau écrasé par au moins deux jeux d'éléments presseurs.The invention relates to a peristaltic pump, and in particular to a peristaltic hose pump crushed by at least two sets of pressing elements.

On connaît de telles pompes pour le pompage de produits liquides, visqueux et/ou granuleux, comme par exemple du béton.Such pumps are known for pumping liquid, viscous and / or granular products, such as for example concrete.

Ces pompes comportent deux jeux de rouleaux radiaux et opposés par rapport au rotor supportant et entraînant en rotation ces jeux de rouleaux. Dans chaque jeu de rouleaux, deux rouleaux sont solidaires en étant espacés l'un de l'autre d'une largeur telle que les deux parois du tuyau sont en contact et suffisamment comprimées pour assurer l'étanchéité du tuyau lors du pompage.These pumps comprise two sets of radial rollers and opposed relative to the supporting rotor and rotating these sets of rollers. In each set of rolls, two rollers are integral with being spaced from each other by a width such that the two walls of the pipe are in contact and sufficiently compressed to seal the pipe during pumping.

Les pompes péristaltiques utilisent un tuyau en élastomère élastique d'un coût relativement élevé, dont il est important d'assurer une durée de vie maximale.Peristaltic pumps use a relatively high cost elastic elastomeric hose, which is important to ensure maximum service life.

Les Figures 1 à 3 montrent une telle pompe péristaltique 1 de l'art antérieur. Cette pompe comprend un rotor 2 fixé sur un arbre d'entraînement 3. Sur ce rotor 2 sont fixés deux jeux 4, 5 symétriquement opposés de deux rouleaux 6, 7 mobiles en rotation autour de leur axe longitudinal 8.The Figures 1 to 3 show such a peristaltic pump 1 of the prior art. This pump comprises a rotor 2 fixed on a drive shaft 3. On this rotor 2 are fixed two sets 4, 5 symmetrically opposite of two rollers 6, 7 rotatable about their longitudinal axis 8.

Les deux rouleaux 6, 7 de chaque jeu 4, 5 sont placés de part et d'autre du tuyau 9 de la pompe 1 en étant espacés d'une largeur e sensiblement égale ou inférieure à la double épaisseur des parois 10, 11 du tuyau 9, de sorte à assurer l'étanchéité au droit de l'écrasement du tuyau 9.The two rollers 6, 7 of each set 4, 5 are placed on either side of the pipe 9 of the pump 1 being spaced apart by a width e substantially equal to or less than the double thickness of the walls 10, 11 of the pipe 9, so as to ensure the tightness to the right of the crushing of the pipe 9.

Lors du déplacement des jeux 4, 5 de rouleaux de l'entrée 12 de la pompe 1 vers la sortie 13 de celle-ci, par rotation du rotor, la portion de tuyau 9 écrasée reprend se forme cylindrique initiale après passage de ces jeux de rouleaux.When the sets 4, 5 of the rollers of the inlet 12 of the pump 1 are moved towards the outlet 13 thereof, by rotation of the rotor, the crushed pipe portion 9 resumes an initial cylindrical shape after passing these sets of tubes. rolls.

Par le déplacement, ou rotation, des jeux 4, 5 de rouleaux, le produit contenu dans le tuyau 9 est aspiré à l'entrée 12 de la pompe 1 et est refoulé à la sortie 13. La rotation continue du rotor 2 assure par conséquent un débit de pompage du produit aspiré à l'entrée 12, puis refoulé à la sortie 13.By the displacement or rotation of the sets 4, 5 of rollers, the product contained in the pipe 9 is sucked at the inlet 12 of the pump 1 and is discharged at the outlet 13. The continuous rotation of the rotor 2 therefore ensures a pumping rate of the product sucked at the inlet 12, then discharged at the outlet 13.

Le débit de pompage est naturellement proportionnel à la vitesse de rotation du rotor 2 et à la section intérieure du tuyau 9. La rotation de l'axe d'entraînement 3 du rotor 2 de la pompe 1 est assurée par une motorisation non représentée.The pumping rate is naturally proportional to the speed of rotation of the rotor 2 and to the inner section of the pipe 9. The rotation of the axis drive 3 of the rotor 2 of the pump 1 is provided by an engine not shown.

Les rouleaux 6, 7 de chaque jeu 4, 5 sont cylindriques et des galets radiaux cylindriques 14 et des galets axiaux cylindriques 15 fixés sur le rotor 2 guident le tuyau 9 en le maintenant en position centrée sur le rotor 2.The rollers 6, 7 of each set 4, 5 are cylindrical and cylindrical radial rollers 14 and cylindrical axial rollers 15 fixed on the rotor 2 guide the pipe 9 by maintaining it in a centered position on the rotor 2.

Cependant, cette pompe 1 présente de nombreux inconvénients.However, this pump 1 has many disadvantages.

Tout d'abord, on observe que les galets cylindriques axiaux 15 ont tendance à s'encastrer latéralement en 16 dans le tuyau 9 sous la tension de celui-ci, puisque ces galets 15 ne portent qu'en un point. Ils déforment, par conséquent, la cylindricité de ce tuyau 9 et réduisent sa capacité d'aspiration.Firstly, it is observed that the axial cylindrical rollers 15 tend to be laterally embedded in 16 in the pipe 9 under the tension thereof, since these rollers 15 bear only one point. They deform, therefore, the cylindricity of this pipe 9 and reduce its suction capacity.

De plus, un châssis de rétention onéreux 17 est nécessaire pour éviter au tuyau 9 de s'échapper vers l'extérieur.In addition, an expensive retention frame 17 is necessary to prevent the pipe 9 from escaping to the outside.

On observe, en effet, lors de la rotation de ces jeux 4, 5 de rouleaux, l'application d'un effort de traction sur la partie du tuyau 9 située en amont de ces jeux 4, 5 qui tend donc à s'allonger sous cet effort, provoquant ainsi un flambement de la partie du tuyau 9 située en aval de ces jeux 4, 5 qui doit donc être maintenue par ce châssis extérieur 17.Indeed, during the rotation of these sets 4, 5 rollers, the application of a tensile force on the portion of the pipe 9 located upstream of these games 4, 5 which tends to lie down under this force, thus causing a buckling of the portion of the pipe 9 located downstream of these games 4, 5 which must be maintained by the outer frame 17.

Par ailleurs, l'écrasement du tuyau 9 par des rouleaux cylindriques 6, 7 produit une vitesse linéaire variable V1, V2, V3 sur leur ligne de contact avec la paroi du tuyau 9, créant ainsi un glissement entre ce dernier et les rouleaux provoquant ainsi une usure de la paroi extérieure du tuyau ainsi qu'un échauffement de celui-ci préjudiciable à la durée de vie du tuyau 9.Furthermore, the crushing of the pipe 9 by cylindrical rollers 6, 7 produces a variable linear velocity V 1 , V 2 , V 3 on their line of contact with the wall of the pipe 9, thus creating a sliding between the latter and the rollers thus causing wear of the outer wall of the pipe and heating thereof, detrimental to the life of the pipe 9.

Egalement, lorsque les jeux 4, 5 de rouleaux cylindriques se présentent devant le tuyau 9 pour l'écraser lors de la rotation du rotor, l'arête vive 18 située à l'extrémité de chaque rouleau 6, 7 attaque la paroi extérieure du tuyau 9 et l'endommage réduisant ainsi également la durée de vie du tuyau 9.Also, when the sets 4, 5 of cylindrical rollers are in front of the pipe 9 to crush during the rotation of the rotor, the sharp edge 18 located at the end of each roller 6, 7 attacks the outer wall of the pipe 9 and the damage thereby also reducing the life of the pipe 9.

En outre, lorsque la pompe 1 n'est pas mise en oeuvre, elle peut rester arrêtée pendant un temps variable allant de quelques heures à plusieurs mois. Le tuyau 9 reste alors écrasé par au moins un des deux jeux 4, 5 de rouleaux pendant toute la période de non utilisation de la pompe 1. Il s'ensuit alors une déformation permanente de l'élastomère du tuyau 9 réduisant ainsi très sensiblement la capacité d'aspiration de ce tuyau 9.In addition, when the pump 1 is not implemented, it can remain stopped for a variable time ranging from a few hours to several months. The pipe 9 then remains crushed by at least one of the two sets 4, 5 rollers during the entire period of non-use of the pump 1. It then follows a permanent deformation of the elastomer of the pipe 9 thus significantly reducing the suction capacity of this hose 9.

Il peut même en résulter une diminution de la capacité d'aspiration du tuyau telle que la pompe 1 n'est plus en état de pouvoir pomper et déplacer du produit.It may even result in a decrease in the suction capacity of the pipe such that the pump 1 is no longer able to pump and move the product.

De surcroît, l'effort d'écrasement du tuyau 9 par les rouleaux 6, 7 espacés de la largeur e doit être celui nécessaire à assurer l'étanchéité lors du pompage du produit à la pression maximale pouvant être utilisée. De ce fait, l'élastomère du tuyau 9 est toujours soumis à une déformation maximale, non nécessaire lorsque la pression de pompage est plus faible.In addition, the crushing force of the pipe 9 by the rollers 6, 7 spaced from the width e must be that necessary to ensure sealing when pumping the product to the maximum pressure that can be used. As a result, the elastomer Pipe 9 is always subject to maximum deformation, not necessary when the pumping pressure is lower.

Enfin, lors de la rotation du rotor 2, lorsqu'un des jeux 4, 5 de rouleaux quitte le contact du tuyau 9 à proximité de la sortie 13 de la pompe 1, les deux rouleaux 6, 7 ne sont plus entraînés par leur frottement sur le tuyau 9 et ils s'arrêtent donc de tourner. Aussi, lorsque après une certaine rotation du rotor 2, ces rouleaux 6, 7 se présentent au niveau de l'entrée 12 de la pompe 1, ils entrent en contact avec la paroi extérieure du tuyau 9 avec une vitesse de rotation nulle et sont donc brutalement mis en rotation. Il en résulte un endommagement de la paroi extérieure du tuyau 9 au droit des deux impacts provoqués par les deux rouleaux 6, 7, diminuant ainsi la durée de la vie dudit tuyau 9.Finally, when the rotor 2 rotates, when one of the sets 4, 5 of rollers leaves the contact of the pipe 9 near the outlet 13 of the pump 1, the two rollers 6, 7 are no longer driven by their friction. on the pipe 9 and they stop to turn. Also, when after a certain rotation of the rotor 2, these rollers 6, 7 are at the inlet 12 of the pump 1, they come into contact with the outer wall of the pipe 9 with a zero rotation speed and are therefore suddenly rotated. This results in damage to the outer wall of the pipe 9 to the right of the two impacts caused by the two rollers 6, 7, thus reducing the life of said pipe 9.

Enfin, on connaît également du document DE 2 040 034 une transmission primaire pour pompes à tuyau flexible afin de permettre l'utilisation de ces pompes comme pompes doseuses volumétriques.Finally, we also know from the document DE 2,040,034 a primary transmission for flexible hose pumps to allow the use of these pumps as volumetric metering pumps.

Le document WO 2005/115884 divulgue également un procédé qui permet de transporter un produit entre un premier et un deuxième point d'une usine de production de purée ou de jus. Ce procédé fait intervenir une conduite dans laquelle coule le produit, cette conduite ayant une partie flexible pouvant être pressée afin d'ajuster le débit du produit dans cette conduite le long d'un sens prédéterminé.The document WO 2005/115884 also discloses a method for conveying a product between a first and second point of a mash or juice plant. This method involves a pipe in which the product flows, which pipe has a flexible portion that can be pressed to adjust the flow rate of the product in that pipe along a predetermined direction.

L'objectif de la présente invention est donc de proposer une pompe péristaltique, simple dans sa conception et dans son mode opératoire, permettant de supprimer les inconvénients des pompes de l'état de l'art.The objective of the present invention is therefore to provide a peristaltic pump, simple in its design and its operating mode, to eliminate the disadvantages of pumps of the state of the art.

A cet effet, l'invention concerne une pompe péristaltique comprenant au moins un tuyau aplatissable élastiquement et au moins deux ensembles de deux éléments presseurs placés en vis-à-vis, chacun desdits ensembles étant destiné à écraser le tuyau en un point différent de la pompe.For this purpose, the invention relates to a peristaltic pump comprising at least one elastically flattenable pipe and at least two sets of two pressing elements placed opposite, each of said sets being intended to crush the pipe at a different point of the pump.

Selon l'invention, les deux éléments presseurs d'un même ensemble étant placés de part et d'autre du tuyau, au moins un des éléments presseurs dudit même ensemble est mobile de sorte que la distance séparant les éléments presseurs de ce même ensemble est ajustable, quelque soit ledit point de la pompe où ledit ensemble d'éléments presseurs est destiné à écraser ledit tuyau, pour permettre de placer les éléments presseurs dans une position de repos dans laquelle le tuyau n'est pas écrasé par ces éléments presseurs ou de placer ces éléments presseurs dans une position d'écrasement dudit tuyau.According to the invention, the two pressing elements of the same assembly being placed on either side of the pipe, at least one of the pressing elements of said same assembly is movable so that the distance separating the pressing elements of the same assembly is adjustable, whatever said point of the pump where said set of pressing elements is intended to crush said pipe, to allow placing the pressure elements in a rest position in which the pipe is not crushed by these pressing elements or placing these pressing elements in a crushing position of said pipe.

  • at least the pressing elements placed on the same first side of this pipe are controlled by at least one actuator able to move these pressing elements between a rest position where the pressing elements are placed behind the pressing elements placed on the other side the pipe without pressing the latter and a so-called crushing position of the pipe,
  • this or these actuators automatically move the pressing elements to the crushing position of the pipe during the startup of the peristaltic pump or pumping, and conversely to the rest position when stopping the peristaltic pump or pumping in order to release said pipe,

Dans une version particulière d'exécution de la pompe péristaltique celle-ci est munie d'un circuit d'alimentation hydraulique qui alimente le moteur d'entraînement du rotor.In a particular version of execution of the peristaltic pump it is provided with a hydraulic supply circuit which supplies the rotor drive motor.

Une dérivation de ce circuit hydraulique par un distributeur hydraulique spécifique permet de commander le ou les actionneurs réalisés par un ou plusieurs vérins hydrauliques.A derivation of this hydraulic circuit by a specific hydraulic distributor allows to control the actuator or actuators made by one or more hydraulic cylinders.

Lors de l'arrêt de la pompe péristaltique, et donc du circuit d'alimentation hydraulique, le ou les vérins ne sont plus en pression et le tuyau est libéré.When stopping the peristaltic pump, and therefore the hydraulic supply circuit, the cylinder or cylinders are no longer in pressure and the pipe is released.

Lors de la mise en route de la pompe péristaltique, le circuit d'alimentation hydraulique est mis sous pression et le distributeur spécifique actionne le ou les vérins qui écrasent le tuyau.When starting the peristaltic pump, the hydraulic supply circuit is pressurized and the specific distributor actuates the cylinder or cylinders that crush the pipe.

Dans un mode de réalisation alternatif, le déplacement automatique du ou des actionneurs est seulement réalisé lors de la mise en route du pompage, c'est-à-dire lorsque l'opérateur décide de pomper effectivement le matériau par activation d'un moyen de commande qui met sous pression le circuit d'alimentation hydraulique actionnant simultanément le moteur d'entraînement du rotor et le ou les actionneurs, comme il a été décrit plus haut.In an alternative embodiment, the automatic movement of the actuator (s) is only performed when the pumping is started, that is to say when the operator decides to actually pump the material by activating a means of control that pressurizes the hydraulic supply circuit simultaneously actuating the rotor drive motor and the actuator (s) as described above.

On évite ainsi d'endommager le tuyau lorsque la pompe n'est pas mise en service.

  • au moins un des éléments presseurs placés d'un même côté du tuyau est mobile par rapport aux autres éléments presseurs placés du même côté du tuyau, Ledit au moins un élément presseur mobile par rapport aux autres permet, par exemple, un déplacement temporaire de cet élément presseur pour faciliter le passage dans le tuyau d'un élément matériel susceptible d'être bloqué autrement par des éléments presseurs fixes en position, bloquant de ce fait la rotation de la pompe péristaltique.
This prevents damage to the hose when the pump is not put into service.
  • at least one of the pressing elements placed on the same side of the pipe is movable relative to the other pressing elements placed on the same side of the pipe, Said at least one movable pressing element relative to the others allows, for example, a temporary displacement of this pressing element to facilitate the passage in the pipe of a material element may be blocked otherwise by pressing elements fixed in position, thereby blocking the rotation of the peristaltic pump.

Ce déplacement peut être provoqué par un écartement temporaire des parois du tuyau au passage de cet élément matériel, l'élément presseur ne faisant que suivre le déplacement de la paroi du tuyau avec lequel il est en contact.

  • l'effort d'écrasement appliqué par les éléments presseurs sur le tuyau en position d'écrasement est proportionnel à la pression de pompage de manière à adapter l'effort d'écrasement pour conserver l'étanchéité,
This displacement can be caused by a temporary spacing of the walls of the pipe to the passage of this material element, the pressure member only following the displacement of the wall of the pipe with which it is in contact.
  • the crushing force applied by the pressing elements on the pipe in the crushing position is proportional to the pumping pressure so as to adapt the crushing force to maintain the seal,

En d'autres termes, l'effort d'écrasement appliqué par les éléments presseurs sur le tuyau en position d'écrasement est proportionnel au couple d'entraînement du rotor portant les éléments presseurs et de l'arbre d'entraînement de ce rotor.

  • le tuyau est maintenu en position et centré dans le corps de la pompe par des galets diabolos fixes ou mobiles, chacun de ces galets diabolos comprenant un logement apte à recevoir et guider ledit tuyau,
In other words, the crushing force applied by the pressure elements on the pipe in the crushing position is proportional to the driving torque of the rotor carrying the pressing elements and the drive shaft of this rotor.
  • the pipe is held in position and centered in the body of the pump by fixed or movable diabolic rollers, each of these diabolic rollers comprising a housing adapted to receive and guide said pipe,

Ces galets diabolos ont un logement interne ayant un diamètre sensiblement égal au diamètre extérieur du tuyau. Les galets diabolos mobiles permettent de suivre le tuyau lors son déplacement.

  • au moins certains desdits éléments presseurs étant des rouleaux mobiles en rotation montés radialement sur un rotor et le tuyau formant sensiblement un U dans la pompe, la pompe comprend une entretoise d'épaisseur égale, ou sensiblement égale, à l'épaisseur du tuyau écrasé, cette entretoise étant placée entre les bras de ce U dans la pompe pour permettre auxdits rouleaux de continuer à être entraînés en rotation lorsque lesdits rouleaux ne sont plus en contact avec ledit tuyau lors de la rotation de ce rotor,
These diabolic rollers have an internal housing having a diameter substantially equal to the outside diameter of the pipe. The mobile diabolic rollers make it possible to follow the pipe during its displacement.
  • at least some of said pressing elements being rotatable rollers mounted radially on a rotor and the pipe forming substantially a U in the pump, the pump comprises a spacer of equal thickness, or substantially equal to the thickness of the crushed pipe, this spacer being placed between the arms of this U in the pump to allow said rollers to continue to be rotated when said rollers are no longer in contact with said pipe during the rotation of this rotor,

On entend par "tuyau formant sensiblement un U" que le tuyau à une forme semi-circulaire ou en C. L'entretoise est placée entre ces bras de manière à former une surface d'entraînement sensiblement continue pour les rouleaux afin de maintenir ceux-ci en rotation. On évite ainsi que les rouleaux n'attaquent le tuyau avec une vitesse de rotation nulle et ne butent sur le tuyau ce qui peut entraîner une fragilisation de ce dernier.The term "substantially U-shaped pipe" means that the pipe has a semicircular or C-shaped shape. The spacer is placed between these arms so as to form a substantially continuous drive surface for the rollers in order to maintain those in rotation. This prevents the rollers from attacking the pipe with a zero rotation speed and do not stop on the pipe which can cause embrittlement of the pipe.

Les deux ensembles de rouleaux sont de préférence montés radialement à l'opposé l'un de l'autre afin de transporter une quantité maximale de matériau liquide ou à base de particules ou de grains tel que du béton.

  • les éléments presseurs sont des rouleaux mobiles en rotation autour de leur axe longitudinal, ayant une forme conique,
  • les rouleaux comportent une extrémité arrondie,
The two sets of rollers are preferably mounted radially opposite each other in order to carry a maximum quantity of liquid or particle-based material or grains such as concrete.
  • the pressing elements are rollers rotatable about their longitudinal axis, having a conical shape,
  • the rollers have a rounded end,

Alternativement, les éléments presseurs d'un même ensemble peuvent ne pas être identiques.Alternatively, the pressing elements of the same set may not be identical.

Ainsi, à titre purement illustratif, un seul élément presseur de cet ensemble pourrait être mobile de manière à permettre l'ajustement de la distance séparant ces éléments presseurs d'un même ensemble, l'autre élément presseur étant fixe et formé par une paroi fixe, de préférence plane.Thus, purely for illustrative purposes, a single pressing element of this assembly could be movable so as to allow the adjustment of the distance separating these pressing elements from the same assembly, the other pressing element being fixed and formed by a fixed wall , preferably plane.

Cette paroi fixe pourrait être formée par le châssis du corps de la pompe péristaltique par exemple.This fixed wall could be formed by the frame of the body of the peristaltic pump for example.

Ainsi, lorsque la pompe péristaltique est en opération, l'élément presseur mobile, par exemple un rouleau, est déplacé pour venir écraser le tuyau contre la paroi fixe de manière à provoquer l'étanchéité.Thus, when the peristaltic pump is in operation, the movable pressing element, for example a roller, is moved to crush the pipe against the fixed wall so as to cause sealing.

Avantageusement la surface de cette paroi fixe destinée à recevoir le tuyau à écraser peut comporter de plus un revêtement adhérent pour empêcher tout glissement longitudinal de ce tuyau lors de son écrasement. Ce revêtement adhérent peut être formé par exemple par une bande en élastomère.

  • le tuyau comprend dans son épaisseur au moins une nappe d'un ou plusieurs câbles placés sur le diamètre primitif d'enroulement.
Advantageously, the surface of this fixed wall intended to receive the pipe to be crushed may further comprise an adherent coating to prevent any longitudinal sliding of this pipe during its crushing. This adherent coating may be formed for example by an elastomeric strip.
  • the pipe comprises in its thickness at least one sheet of one or more cables placed on the pitch winding diameter.

Les figures 4 à 7 représentent schématiquement une pompe péristaltique selon un mode de réalisation particulier de l'invention. Cette pompe 1 ayant été réalisée en adaptant conformément à l'invention une pompe de l'art antérieur telle que décrite aux figures 1 à 3, les éléments repérés sur les Figures 4 à 7 par les mêmes références que sur les Figures 1 à 3, représentent les mêmes objets.The Figures 4 to 7 schematically represent a peristaltic pump according to a particular embodiment of the invention. This pump 1 having been made by adapting according to the invention a pump of the prior art as described in Figures 1 to 3 , the elements identified on the Figures 4 to 7 by the same references as on the Figures 1 to 3 , represent the same objects.

Les deux jeux 4, 5 de rouleaux diamétralement opposés par rapport à l'axe de rotation du rotor comprennent chacun deux rouleaux 20, 20', 21, 21' ayant une forme conique d'angle approprié permettant de réduire, voir supprimer le glissement entre ces rouleaux et le tuyau, ce qui améliore la durée de vie de ce dernier.The two sets 4, 5 diametrically opposed rollers relative to the axis of rotation of the rotor each comprise two rollers 20, 20 ', 21, 21' having a conical shape of appropriate angle to reduce, or remove the sliding between these rollers and the pipe, which improves the life of the latter.

Ces rouleaux coniques 20, 20', 21, 21' présentent chacun une extrémité arrondie 22, 23 de façon à ce qu'ils entrent progressivement en contact lors de leur arrivée en rotation sur la partie du tuyau placée à proximité de l'entrée 12, évitant ainsi un arrachement superficiel de la paroi extérieure du tuyau 9.These tapered rollers 20, 20 ', 21, 21' each have a rounded end 22, 23 so that they gradually come into contact upon their arrival in rotation on the part of the pipe placed near the inlet 12 , thus avoiding a superficial tearing of the outer wall of the pipe 9.

Le rotor 2 comporte d'une part un flasque fixe 24 entraîné par l'arbre d'entraînement 3, lui-même mis en rotation par une motorisation non représentée.The rotor 2 comprises firstly a fixed flange 24 driven by the drive shaft 3, itself rotated by an engine not shown.

Ce rotor comporte d'autre part un flasque 25 susceptible de pivoter autour d'un axe 26, lui-même solidaire d'une bague coulissante 27 sur l'arbre d'entraînement 3 et entraînée en rotation par clavetage coulissant par ledit arbre 3.This rotor further comprises a flange 25 capable of pivoting about an axis 26, itself secured to a sliding ring 27 on the drive shaft 3 and driven in rotation by sliding keying by said shaft 3.

Cette bague 27 comprend une chambre 28 de réception d'un fluide hydraulique et constitue avec le piston 29 lui-même solidaire de l'axe 3 un vérin actionneur.This ring 27 comprises a chamber 28 for receiving a hydraulic fluid and constitutes with the piston 29 itself secured to the axis 3 an actuator cylinder.

Au repos, ce vérin actionneur est sollicité vers le bas par le ressort 30 s'appuyant sur le piston 29 lui-même solidaire de l'axe 3, et par conséquent, le flasque 25 solidaire de la bague 27 est donc sollicité vers le bas et le tuyau 9 n'est pas écrasé.At rest, this actuator cylinder is biased downwardly by the spring 30 bearing on the piston 29 itself secured to the axis 3, and therefore the flange 25 secured to the ring 27 is biased downwards. and the pipe 9 is not crushed.

Si l'on introduit un fluide sous pression dans la chambre 28 par l'orifice 31 lui-même alimenté par un joint tournant 32, le vérin actionneur déplace en sens inverse, donc vers le haut, la bague coulissante 27 et, par conséquent, le flasque 25.If a pressurized fluid is introduced into the chamber 28 through the orifice 31 itself fed by a rotary joint 32, the actuating cylinder displaces the sliding ring 27 in the opposite direction, and therefore upwards, and, consequently, the flange 25.

Par conséquent, si le fluide est sous pression, le flasque mobile 25 se déplace et les deux rouleaux 21, 21' reliés à ce flasque viennent écraser le tuyau 9 contre les rouleaux 20, 20' montés sur le flasque fixe 24. Le tuyau 9 est ainsi écrasé et l'étanchéité dudit tuyau est assurée.Therefore, if the fluid is under pressure, the movable flange 25 moves and the two rollers 21, 21 'connected to this flange crush the pipe 9 against the rollers 20, 20' mounted on the fixed flange 24. The pipe 9 is thus crushed and the sealing of said pipe is ensured.

L'effort d'écrasement du tuyau 9 sera proportionnel à la pression du fluide entrant dans la chambre 28.The crushing force of the pipe 9 will be proportional to the pressure of the fluid entering the chamber 28.

Cette pression du fluide pourra être proportionnelle à la pression de pompage du produit et ainsi assurer l'étanchéité nécessaire correspondant à la pression de pompage. L'élastomère du tuyau 9 ne sera sollicité qu'autant que nécessaire, améliorant ainsi sa durée de vie.This pressure of the fluid may be proportional to the pumping pressure of the product and thus provide the necessary seal corresponding to the pumping pressure. The elastomer of the pipe 9 will be solicited only as necessary, thus improving its service life.

La motorisation de l'arbre 3 et donc des deux flasques 24, 25 est réalisée par une transmission hydraulique. Le couple d'entraînement en rotation de l'arbre 3 est proportionnel à la pression de pompage du produit.The motorization of the shaft 3 and thus of the two flanges 24, 25 is achieved by a hydraulic transmission. The driving torque in rotation of the shaft 3 is proportional to the pumping pressure of the product.

La pression du circuit hydraulique de motorisation sera elle-même proportionnelle au couple d'entraînement, donc à la pression de pompage du produit.The pressure of the hydraulic motorization circuit will itself be proportional to the driving torque, and therefore to the pumping pressure of the product.

Donc si le vérin actionneur est alimenté par cette pression hydraulique, il exercera un effort d'écrasement du tuyau 9 proportionnellement à la pression de pompage.So if the actuator cylinder is powered by this hydraulic pressure, it will exert a crushing force of the pipe 9 proportionally to the pumping pressure.

Le flasque 25 étant mobile en pivotement autour de son axe 26, et coulissant sur l'arbre 3, l'un ou l'autre des rouleaux 21, 21' pourra se soulever indépendamment dans l'hypothèse où il rencontrerait un agrégat bloqué dans le tuyau 9, évitant ainsi que cet agrégat n'endommage ou ne perfore le tuyau 9.The flange 25 being pivotally movable about its axis 26, and sliding on the shaft 3, one or the other of the rollers 21, 21 'can lift independently in the event that it encounters an aggregate blocked in the pipe 9, thus avoiding that this aggregate does not damage or perforate the pipe 9.

On constate que si à la mise en marche de la motorisation de la pompe péristaltique ou lors du démarrage du pompage, on envoie du fluide sous pression dans la chambre 28, les deux rouleaux 21, 21' compriment le tuyau 9 et assurent ainsi l'étanchéité nécessaire au pompage du produit.It can be seen that if, at the start of the motorization of the peristaltic pump or during the start of pumping, pressurized fluid is sent into the chamber 28, the two rollers 21, 21 'compress the pipe 9 and thus ensure the sealing required to pump the product.

Inversement, à l'arrêt de la motorisation de la pompe péristaltique ou lors de l'arrêt du pompage, on n'envoie plus de fluide sous pression dans la chambre 28, le ressort 30 entraînera en sens inverse le flasque mobile 25 et les deux rouleaux correspondant 21, 21' libéreront le tuyau 9 qui ne sera donc pas écrasé pendant l'arrêt de la pompe 1 évitant ainsi une déformation permanente de l'élastomère du tuyau 9. On améliore ainsi considérablement la durée de vie de ce tuyau, et sa capacité d'aspiration.Conversely, upon stopping the motorization of the peristaltic pump or when stopping the pumping, no more pressurized fluid is sent into the chamber 28, the spring 30 will drive the mobile flange 25 and the two in the opposite direction. corresponding rollers 21, 21 'will release the pipe 9 which will not be crushed during the stoppage of the pump 1 thus avoiding permanent deformation of the elastomer of the pipe 9. This considerably improves the life of this pipe, and its suction capacity.

Si la pompe 1 est disposée en position sensiblement verticale comme représentée sur la figure 6, il apparaît que le ressort de rappel 30 peut être supprimé. En effet, le flasque mobile 25 peut descendre par effet de gravité, lorsque du fluide sous pression n'est pas injecté.If the pump 1 is disposed in a substantially vertical position as shown in FIG. figure 6 it appears that the return spring 30 can be removed. Indeed, the movable flange 25 can descend by gravity effect, when pressurized fluid is not injected.

Sur les figures 4 et 6 et la vue en coupe de la figure 7, on voit que la partie du tuyau non écrasée 9 située entre les deux jeux 4, 5 de rouleaux est maintenue et centrée par des galets diabolos 33 tournant autour de leur axe 34, et positionnés sur le flasque fixe 24. Ces galets diabolos 33 peuvent aussi se mouvoir axialement le long de leur axe 34 pour suivre les mouvements axiaux du tuyau 9, lors du positionnement des jeux 4, 5 de rouleaux dans leur position de repos ou leur position d'écrasement.On the figures 4 and 6 and the sectional view of the figure 7 it can be seen that the part of the uncrushed pipe 9 located between the two sets 4, 5 of rollers is held and centered by diabolic rollers 33 rotating about their axis 34, and positioned on the fixed flange 24. These diabolic rollers 33 can also move axially along their axis 34 to follow the axial movements of the pipe 9, when positioning the games 4, 5 rollers in their rest position or their crushing position.

Le diamètre intérieur de ces galets diabolos 33 est sensiblement égal à celui extérieur du tuyau 9 de façon à lui permettre de l'aider à retrouver, en sus de sa propre élasticité, sa forme cylindrique et favoriser ainsi son pouvoir d'aspiration.The inner diameter of these diabolic rollers 33 is substantially equal to that outside the pipe 9 so as to enable it to help find, in addition to its own elasticity, its cylindrical shape and thus promote its suction power.

A ce titre, les galets diabolos 33 remplacent avantageusement les galets axiaux 15 et les galets radiaux 14 d'une pompe de l'état de l'art (Figure 1).In this respect, the diabolic rollers 33 advantageously replace the axial rollers 15 and the radial rollers 14 of a pump of the state of the art ( Figure 1 ).

Une entretoise 35 est fixée entre l'entrée 12 et la sortie 13 du tuyau 9, dans le plan de l'axe dudit tuyau. Elle est d'une épaisseur sensiblement égale à celle du tuyau écrasé 9 de manière à pouvoir entretenir en rotation les rouleaux sans avoir à déplacer le flasque mobile 25.A spacer 35 is fixed between the inlet 12 and the outlet 13 of the pipe 9, in the plane of the axis of said pipe. It is of a thickness substantially equal to that of the crushed pipe 9 so as to be able to maintain the rollers in rotation without having to move the mobile flange 25.

Ainsi, lorsque l'un des deux jeux 4, 5 de rouleaux quitte le tuyau 9 en sortie 13, les rouleaux 20, 20', 21, 21' continuent à s'appuyer sur cette entretoise 35 et continuent donc à être entraînés en rotation.Thus, when one of the two sets 4, 5 of rollers leaves the pipe 9 at the outlet 13, the rollers 20, 20 ', 21, 21' continue to rest on this spacer 35 and therefore continue to be rotated. .

Aussi, lorsque lesdits rouleaux entrent en contact, sur l'entrée 12 du tuyau 9, ils sont déjà en rotation et n'altèrent pas la paroi extérieure dudit tuyau.Also, when said rollers come into contact with the inlet 12 of the pipe 9, they are already rotating and do not alter the outer wall of said pipe.

Un autre exemple de réalisation conforme à l'invention, mais non représenté, peut être constitué par deux ensembles symétriquement opposés de deux jeux de flasques mobiles 25 équipés chacun d'une chambre 28 et d'un piston 29 formant un vérin actionneur.Another embodiment according to the invention, but not shown, may be constituted by two symmetrically opposite sets of two sets of movable flanges 25 each equipped with a chamber 28 and a piston 29 forming an actuator cylinder.

Un autre exemple de réalisation de l'invention, non représenté, peut être réalisé par plus de deux jeux 4, 5 de rouleaux.Another embodiment of the invention, not shown, can be achieved by more than two sets 4, 5 rollers.

D'autres exemples de réalisations conformes à l'invention, non représentés, peuvent être réalisés par l'utilisation de moyens électrique hydraulique ou pneumatique pouvant exercer un effort d'écrasement et de retrait, en remplacement de la chambre 28 et du piston 29 formant un vérin actionneur.Other examples of embodiments according to the invention, not shown, can be achieved by the use of hydraulic or pneumatic electric means that can exert a crushing and withdrawal force, replacing the chamber 28 and the piston 29 forming an actuator cylinder.

Le tuyau 9 sera avantageusement renforcé par une nappe 40 constituée d'un ou plusieurs câbles 41, 42, 43 disposée sur le diamètre primitif d'enroulement dudit tuyau. Cette nappe 40 pourrait avant avantageusement être doublée par une seconde nappe 41, constituée elle-même d'un ou plusieurs câbles 41', 42', 43', et opposée symétriquement à ladite première nappe.The pipe 9 will advantageously be reinforced by a ply 40 consisting of one or more cables 41, 42, 43 disposed on the pitch diameter of said pipe. This ply 40 could advantageously be doubled by a second ply 41, itself constituted by one or more cables 41 ', 42', 43 ', and symmetrically opposed to said first ply.

Cette nappes longitudinales permettent de conserver une longueur constante au tuyau 9, quelque soit l'effort de traction exercé par les jeux 4, 5 de rouleaux, et maintiennent ainsi le tuyau centré sur les jeux de rouleaux, ce qui permet de supprimer le carter onéreux 17 mis en oeuvre dans les pompes de l'état de l'art.This longitudinal ply makes it possible to maintain a constant length of the pipe 9, regardless of the tensile force exerted by the sets 4, 5 of rollers, and thus keep the pipe centered on the sets of rollers, which makes it possible to remove the expensive casing. 17 implemented in state-of-the-art pumps.

La figure 11 représente schématiquement une pompe péristaltique selon un autre mode de réalisation de l'invention. Les éléments de la figure 11 portant les mêmes références que les éléments de la Figure 6 représente les mêmes objets, lesquels ne seront par conséquent pas décrits de nouveau. La pompe péristaltique de la figure 11 se distingue de celle de la figure 6 en ce que les éléments presseurs 21, 21', 50 d'un même ensemble ne sont pas identiques.The figure 11 schematically represents a peristaltic pump according to another embodiment of the invention. The elements of the figure 11 bearing the same references as the elements of the Figure 6 represents the same objects, which will not be described again. The peristaltic pump of the figure 11 differs from that of the figure 6 in that the pressing elements 21, 21 ', 50 of the same set are not identical.

L'élément presseur 21, 21' situé au-dessous du tuyau 9 dans chaque ensemble est un rouleau mobile tandis que les éléments presseurs placés au dessus de ce tuyau 9 sont constitués par une même paroi fixe 50 et plane.The pressing element 21, 21 'located below the pipe 9 in each set is a mobile roller while the pressing elements placed above this pipe 9 are constituted by the same fixed wall 50 and flat.

Cette paroi fixe 50 comporte de plus un revêtement adhérent 51 destiné à recevoir le tuyau 9 pour empêcher tout glissement longitudinal de celui-ci lors de l'écrasement du tuyau par les ensembles d'éléments presseurs 21, 21', 50.This fixed wall 50 further comprises an adherent coating 51 intended to receive the pipe 9 to prevent any longitudinal sliding thereof during crushing of the pipe by the sets of pressing elements 21, 21 ', 50.

L'arbre d'entraînement 3 traverse la paroi fixe 50 en étant mobile en rotation par rapport à celle-ci. Une butée 52 reprend les efforts d'écrasement du tuyau 9.The drive shaft 3 passes through the fixed wall 50 being rotatable relative thereto. A stop 52 takes up the crushing efforts of the pipe 9.

Cette pompe péristaltique comporte par ailleurs une entretoise (non représentée) d'épaisseur égale, ou sensiblement égale, à l'épaisseur du tuyau 9 écrasé, cette entretoise étant placée entre les bras dudit U dans la pompe péristaltique pour permettre aux rouleaux 21, 21' placés sous le tuyau 9 de continuer à être entraînés en rotation lorsque ces rouleaux 21, 21' ne sont plus en contact avec ledit tuyau 9 lors de la rotation du rotor 2.This peristaltic pump also comprises a spacer (not shown) of equal thickness, or substantially equal to the thickness of the crushed pipe 9, this spacer being placed between the arms of said U in the peristaltic pump to allow the rollers 21, 21 placed under the pipe 9 continue to be rotated when these rollers 21, 21 'are no longer in contact with said pipe 9 during the rotation of the rotor 2.
