Definitions

  • the product does not descend well, or even does not descend at all to the Archimedes screw when its viscosity is too high (phenomenon of arch at the base of the hopper).
  • the object of the invention is essentially to remedy the shortcomings of known installations, by proposing an arrangement which makes it possible to force the product to enter the Moineau pump even when said product has a very high viscosity, which is simple and inexpensive to put into operation. work, which is not bulky, which can possibly be set up in already existing installations and which certainly avoids the formation of an arch.
  • a second Archimedes screw having a winding pitch opposite to that of the above-mentioned first Archimedes screw, this second screw Archimedes being arranged at the base of the filling hopper and extending approximately parallel to the first Archimedes screw, substantially in the same base plane as the latter and, on the other hand, drive means for making turn the second Archimedes screw in the opposite direction to the first.
  • the Applicant has been able to note that the two counter-rotating screws with reverse pitch offered a grinding and kneading capacity much greater than that of the devices of the prior art, which makes it possible to use the device of the invention to convey products in the form of blocks, such as filter cakes constituted by compact rectangular pieces of large dimensions.
  • the second Archimedes screw rotates in synchronism with the first, and the drive means comprise a coupling without sliding, in particular a gear train, interposed between the two screws.
  • the axis of the rotor of a pump Sparrow rotates eccentrically. Therefore, the axis of the first Archimedes screw describes, in the course of rotation, a cone of revolution having its apex its connection to the axis of the drive motor and resting on the circle described by the axis of the Moineau pump rotor.
  • the opening angle of this cone is very small.
  • the second Archimedes screw has a fixed axis in order to simplify the arrangement of the installation.
  • Cardan couplings or the like are provided at the two ends of the Archimedes screw (s), for coupling to the rotor of the corresponding pump, at one end, and coupling to a shaft d corresponding drive at the other end.
  • Such an arrangement makes it possible to dispense with expensive, fragile and bulky transmission devices which are used in certain known installations in which the axis of the Archimedes screw coupled to the rotor of the Moineau pump remains fixed.
  • the two Archimedes' screws can be axially offset with respect to each other and for the distance separating their axes to be less than their diameter.
  • the two helical screws, considered in axial projection are nested one inside the other, which contributes to further increase the thrust exerted on the pasty product to make it penetrate into the pump.
  • the installation for transporting products having a high viscosity comprises a sparrow pump 1 whose rotor 2 is rotatably coupled to one end of an Archimedean screw 3 and is approximately coaxial with said screw.
  • the other end of the Archimedes screw 3 is coupled in rotation to a shaft provided with a system of axial stops 4 and connected, by means of a coupling flange 5, to a motor of training (not shown).
  • Archimedes' screw 3 is further surmounted by a hopper 6 for the product to be transported.
  • a second Archimedes screw 7 which has a winding pitch opposite to that of the screw 3 and which extends approximately parallel to the first screw 3, and the axes of the screws 3 and 7 define a plane (or base plane) which is approximately parallel to the plane of the base opening of the hopper 6.
  • the two screws 3 and have propellers respectively whose pitch is of the same value and of the same diameter, and they are driven in synchronism in opposite directions to each other (counter-rotating screws).
  • the shafts of the screws 3 and 7 are coupled without sliding, by two identical gears 8, 9, wedged directly on their respective shafts and meshing directly with each other.
  • the axis of the Archimedes screw 3 describes a cone whose summit is its junction with the drive motor shaft 10 and based on the circle described by the axis of the pump rotor. Two couplings are therefore provided to the Cardan joint 11 to connect the Archimedes screw 3 respectively to the rotor 2 and to the motor shaft 10.
  • the second Archimedes screw 7 rotates around a fixed axis and its shaft spins in fixed bearings 12 integral with the frame of the installation.
  • the counter-rotation of the Archimedes 3 and 7 screws causes the product to knead, which, by preventing it from freezing, keeps it in a state which facilitates, as much as possible, its flow.
  • the axes of the rotor of the Moineau pump, of the two Archimedes screws, of the drive shafts and of the motor are located in the same basic plane and that, as a result, the hopper can be arranged relatively low compared to this basic plan.
  • the entire installation can therefore be produced in a very compact form or, at least, without any increase in dimensions compared to the dimensions of an installation with a single Archimedean screw. This advantage is particularly interesting because it allows the replacement of a previous installation by an installation according to the invention without the need to provide increased free space.
  • the second Moineau pump 13 is parallel to the first 1 and the axis of its rotor 14 is approximately aligned with that of the second Archimedes screw 7.
  • the second Archimedes screw 7 can no longer have a fixed axis and must, like screw 3, be connected, by couplings to the Cardan joint 15, to the rotor 14 of the pump 13 and the drive shaft 16 on which the counter-rotating coupling gear 9 is flanged, a system of axial stops 17 being also provided in a manner analogous to system 4.
  • the part of the casing 19 which surrounds the two screws in the outlet zone of these (that is to say in their end zone close to the Moineau pump) closely matches the content. outside of the two screws and extends over an axial length which is equal to at least one helix pitch of the screws.
