Definitions
- the invention relates to a peristaltic pump, and in particular to a peristaltic hose pump crushed by at least two sets of pressing elements.
- Such pumps are known for pumping liquid, viscous and / or granular products, such as for example concrete. 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.
- Peristaltic pumps use a relatively high cost elastic elastomeric hose, which is important to ensure maximum service life.
- FIGS 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.
- 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.
- 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.
- 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.
- the pump 1 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.
- 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.
- the elastomer Pipe 9 is always subject to maximum deformation, not necessary when the pumping pressure is lower.
- 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.
- 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.
- 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 set back from the pressure elements placed on the other side of the pipe without pressing the latter and a so-called crushing position of the pipe, - these or these actuators automatically move the elements pressers to the crushing position of the pipe during the startup of the peristaltic pump or pumping, and vice versa to the rest position when stopping the peristaltic pump or pumping to release said pipe,
- a hydraulic supply circuit which supplies the rotor drive motor.
- 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.
- the cylinder or cylinders 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.
- the hydraulic supply circuit When starting the peristaltic pump, the hydraulic supply circuit is pressurized and the specific distributor actuates the cylinder or cylinders that crush the pipe.
- 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.
- 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, Ledit less a 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, blocking this rotates the peristaltic pump.
- 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,
- 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 mobile diabolos, each of these diabolos having a housing adapted to receive and guide said pipe,
- 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.
- 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,
- 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 these 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.
- 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 comprise a rounded end,
- the pressing elements of the same set may not be identical.
- 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.
- This fixed wall could be formed by the frame of the body of the peristaltic pump for example.
- the movable pressing element for example a roller
- 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.

- FIG. 3 is a diagrammatic representation of the cylindrical guide rollers of the pipe of the pump of FIG. 1;
- Figure 4 schematically shows a partial top view of a peristaltic pump according to a particular embodiment of the invention

- FIG. 7 schematically represents a particular view of a diabolo roller holding the pipe of the pump of FIG. 4;
- FIG. 8 represents a sectional view of the pipe of the pump of FIG. 4, this pipe being reinforced by two plies of several cables;
- Figure 9 shows the pipe of Figure 8 in the crushing position;
- Figure 10 is a top view of the pipe of Figure 8;
- 11 schematically shows a sectional view and front view of a peristaltic pump according to another embodiment of the invention, with fixed wall;
- FIGs 4 to 7 schematically show 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 marked in Figures 4 to 7 by the same references as in Figures 1 to 3, represent the same objects.
- 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.
- 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.
- the rotor 2 comprises firstly a fixed flange 24 driven by the drive shaft 3, itself rotated by an engine not shown.
- 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.
- 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.
- 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. 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.
- the crushing force of the pipe 9 will be proportional to the pressure of the fluid entering the chamber 28.
- 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.
- 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.
- the pressure of the hydraulic motorization circuit will itself be proportional to the driving torque, and therefore to the pumping pressure of the product.
- 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.
- the return spring 30 can be eliminated. Indeed, the movable flange 25 can descend by gravity effect, when pressurized fluid is not injected.
- FIGS. 4 and 6 and the sectional view of FIG. 7, it can be seen that the portion of the uncrushed pipe 9 situated 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 of rollers in their rest position or their crush position.
- 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.
- 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).
- 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.
- rollers 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.
- Another embodiment according to the invention 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.
- Another embodiment of the invention can be achieved by more than two sets 4, 5 rollers.
- inventions according to the invention 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.
- 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.
- FIG. 11 schematically shows a peristaltic pump according to another embodiment of the invention.
- the elements of FIG. 11 bearing the same references as the elements of FIG. 6 represent the same objects, which will therefore not be described again.
- the peristaltic pump of FIG. 11 differs from that of FIG. 6 in that the pressing elements 21, 21 ', 50 of the same set are not identical.
- 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.
- 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.
- 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.
- 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.
