Definitions

  • the present invention relates to a diaphragm circulator and more generally to a device by which a mechanical power is transformed into a hydraulic power, that is to say the product of a flow rate by a pressure, for a liquid or gaseous fluid charged or no particles or any material likely to flow (divided, pulverulent, fluidized or emulsion materials ).
  • the document EP 880 650 illustrates several embodiments of such a fluid circulator by highlighting certain conditions to be satisfied so that there is an effective energy transfer between the membrane and the fluid leading to the increase of the fluid hydraulic energy .
  • These conditions are on the one hand the establishment of a tension in the membrane so that there is a propagation of the undulations and on the other hand the presence of means for creating a damping of the amplitude of the undulation during its progression from an edge of the membrane where this ripple is generated by a mechanical actuator to an opposite edge.
  • the state of tension of the membrane is a variable which is correlated with the mechanical characteristics of the material of this membrane.
  • the initial state of tension of the membrane at rest can be zero if for example the membrane is in a material, elastically deformable in at least one direction, associated with a geometry such that a deformation imposed on the membrane generates a voltage in it, in the aforesaid direction, which allows the progression of this deformation in the form of a wave, along this direction which becomes the direction of propagation.
  • This type of membrane will be called, in the following, a membrane having intrinsic means for creating a voltage.
  • a discoidal elastic membrane provided or not with a hole in the center, in which the outer edge remains undetected during its excitation by the actuator while the membrane at rest is not tensioned.
  • It can also be a flat elastic membrane in which the two ends are subjected to forces that oppose the forces imparted to the membrane by the fluid into which the energy is transferred. Thanks to the presence of these forces, the conditions necessary for the propagation of a deformation generated at one end towards the other end are present.
  • a membrane formed by a flat sheet at rest, indeformable in traction in the directions of its plane, but elastically deformable in flexion, for example around an axis contained in this plane constitutes a medium for operating as a membrane according to the invention, if the membrane is subjected to a force of tension or simply of maintenance, perpendicular or having a component perpendicular to the axis around which the flexion occurs.
  • This perpendicular direction is the direction of propagation.
  • a membrane circulator for a flowable material comprising a circulator body in which is provided an internal circuit having at least one inlet orifice of the material, a propulsion chamber and at least one discharge orifice of this material, the propulsion chamber being rigid-walled between which is placed a deformable membrane with an edge close to the inlet orifice and a edge adjacent the discharge port, the membrane forming the support of a corrugation, while a mechanical actuator of the diaphragm is coupled to the diaphragm on the side of the inlet port to apply to the corresponding edge of the diaphragm an alternating force or a pair of alternating forces generating said corrugation, wherein the rigid walls of the circulator are disposed within envelope surfaces of the free amplitude of the undulation propagating along the membrane, and in which the membrane is associated by at least one of its edges to means which generate a tension in the membrane at least during the generation of the ripple so that in operation
  • the term "free amplitude of the undulation" is intended to mean the theoretical or virtual amplitude which has been defined above.
  • This definition is neither revealed nor suggested by circulators of the state of the art (EP 880 650 ), that is to say those which have both a circulation chamber whose walls converge towards each other from the inlet to the exhaust and a membrane in which a tension is voluntarily installed in the flow direction of the fluid.
  • this definition applies to all circulators which, while having a convergent-wall circulation chamber, have a membrane whose dimension in the direction of propagation of the corrugations is fixed by appropriate means so that in the membrane, even without tension.
  • the elongation of the membrane accompanying the creation of a corrugation is generating a voltage in the direction of the propagation of the corrugation, the membrane being or not in a material elastically deformable in the direction of propagation.
  • These are intrinsic means of establishing this condition of tension necessary for propagation.
  • this type of means a frame in the inner plane of which is the membrane, hitched to the end crosses of this frame, or by inextensible means if the membrane is elastic between these two crosspieces, or by extensible means if the membrane is inextensible between the crosspieces (for example a flat sheet - metal or synthetic composite material - which can flex around a direction of its plane).
  • An initial voltage may or may not be installed when mounting the membrane in the frame.
  • the outer deformable strapping of the membrane may be constituted by a bead of the membrane itself, indeformable compared to the efforts involved which may be weak.
  • rigid walls also means walls which may nevertheless have a certain flexibility in the absolute but which behave in the application as rigid walls with respect to all the other materials involved in the apparatus.
  • a portion of the propulsion chamber delimited by the circulator body and one of the faces of the membrane is connected to an inlet for an external supply of material to be treated, in particular to propel, and a discharge port itself connected to the inlet of the other portion of the propulsion chamber defined by the circulator body and the other side of the membrane, this other portion ending at the exhaust port of the circulator, the two chamber portions being further isolated from each other.
  • a circulation stage is created on each side of the membrane, which makes it possible, all things being equal, to obtain a greater pressure performance of the pump or, with equal performance, to be able to choose a membrane material of modulus of elasticity lower but better suited to the chemical specifications of the application. In particular, this increase in performance can be obtained with an unchanged bulk.
  • the circulator comprises a discoidal diaphragm the outer periphery of which is coupled to a movable excitation element guided along an axis perpendicular to the plane of the membrane by a central guide column integral with the body of the circulator.
  • This form of excitation member is advantageous because it concentrates at the central axis of the circulator all the motorization and guiding functions, functions that can be provided in reduced dimensions, which makes it possible to obtain them at low cost. . Motorization and guidance of moving parts are indeed the most expensive functions of the circulator.
  • the circulator according to the invention may have a substantially cylindrical body which defines a plurality of superimposed propulsion spaces connected in series between an intake port and an exhaust port, the membranes of each space being hitched by their outer edge to a single moving motor unit.

  • it is useful to favor the flow rate with respect to the pressure, and thus to cause and propagate an amplitude amplification ripple. important.

  • a plane membrane 1 in section having an end (or an edge) 2 subjected to a force 3 of alternative mechanical excitation of this end 2, perpendicular to the plane of the membrane 1, generated by an electromechanical actuator.
  • the membrane comprises another edge 4 so that between the two edges is defined a direction of propagation 5 for the corrugations generated by the alternating mechanical force 3.

  • Tubular membranes whose edges are each at one end of a tube
  • a voltage of the existing membrane in its state of rest or born of resistance to elongation under the effect of this mechanical stress is represented by forces 6a and 6b.
  • This membrane, then stretched, is the seat of the propagation of the undulation in the direction of the tension.
  • the edge 4 is at infinity, with a membrane of decreasing thickness in the direction 5 of the propagation and / or in the absence of reflection of the undulation, the theoretical free amplitude of the ripple goes increasing from edge 2 to edge 4.
