Definitions

  • the present invention relates to a device for cleaning the interior of a container, using at least one jet of liquid.
  • a nozzle capable of projecting a jet of liquid towards the interior faces of this container, the orientation of this nozzle can be changed to allow the jet to reach substantially all points on the interior surface of the container.
  • the nozzle is mounted at the end of a flexible pipe, and an operator acts manually to send the jet successively to all the points inside the container.
  • the object of the present invention is to provide an apparatus which makes it possible to automatically ensure complete scanning of the entire interior surface of a container, this apparatus being simple to manufacture and inexpensive to maintain.
  • the invention therefore provides a device for projecting a fluid onto the interior faces of an enclosure, comprising: - At least one nozzle capable of projecting a jet of said fluid onto said interior faces of the container, carried by a rotor capable of turning on a first axis yy ′, the nozzle being oriented so that the jet of fluid is tangential to said first axis , so that the jet reaction turns the rotor on said axis, - a hollow rotary head carrying said first axis yy ′, capable of turning on a second axis xx ′ which meets the first at a non-zero angle, the rotary head being provided with an auxiliary nozzle oriented to produce a jet of fluid tangential to said second axis, so that the reaction of this jet turns the rotary head on said axis, - a hollow support which can be immobilized by relative to the enclosure, carries said first axis of the rotary head, said support being capable of serving as a conduit for supplying the fluid
  • tangential jet with respect to an axis is meant a jet which is neither parallel to this axis, nor intersecting it. It is shown that a jet which is neither parallel nor intersecting with respect to an axis necessarily has a component which is tangent to a circle perpendicular to this axis and centered on it. It is the part of the jet reaction force which is directed according to this tangential component which creates the reaction force driving the rotor or the rotary head in rotation relative to the axis.
  • the auxiliary nozzle is supplied with liquid by a bypass of the nozzle supply, the shape and the dimensions of the auxiliary nozzle and of the nozzle are calculated so that the rotational speeds of the rotor and of the head rotary are not in a simple report.
  • said rotor seal surface is conical or planar and directed opposite the second axis xx ′ of rotation of the rotary head, and comes to bear on a corresponding seal surface of the wall of an interior chamber, maintained at atmospheric pressure, of the rotary head, so that the centrifugal force resulting from the rotation of the rotary head tends to force said joint surfaces against each other while the pressure of the fluid inside the hollow rotary head acts in reverse.
  • said inner chamber of the rotary head is connected to the atmosphere by a passage provided inside the rotor.
  • the outer surfaces of the rotor, the rotary head and the support are parts of the same sphere, so that the assembly has the general shape of a sphere mounted at the end of a cylinder.
  • Figure 1 schematically shows a device of the invention designated as a whole by 1, placed inside a container to be cleaned 2, shown in dashes.
  • the device 1 comprises a support tube 3, provided at its upper part with a seal 4 for connection to a duct 5 for supplying the cleaning liquid under pressure.
  • the support tube 3 carries a rotary head 6, which can rotate around the vertical axis xx ′ of the support tube 3.
  • the rotary head 6 is hollow. It carries a tangential nozzle 7, situated in a horizontal plane. When liquid is sent into the head 6, through 1 via the support tube 3, the reaction created by the jet 8 leaving the nozzle 7 tends to rotate the head 6 around the axis xx ′, in the direction indicated by arrow 9.
  • the head 6 carries, in addition, a rotor 10, mounted on a hollow shaft 11, which communicates with the interior of the head 6.
  • the axis yy ′ of the hollow shaft 11, which is also the axis of rotation of the rotor 10, is horizontal.
  • the rotor 10 is itself hollow and in communication with the interior of the shaft 11. It carries two tangential nozzles 12, which, when the system is supplied with flushing liquid, create tangential jets 13, driving the rotor into rotation according to arrow 14.
  • the surface 17, which is located opposite the orifice can be easily cleaned by other means, or else is sufficiently cleaned by the impact of splashes caused by the impact of the jets 13 on the bottom. adjacent.
  • the volume which is not reached by the jets 13 comprises a cylindrical part with a vertical axis including the orifice 18 of the container, and a conical part, the apex of which is at the point where the axis xx ′ crosses the bottom 15 of container 2.
  • Figure 3 shows that the support tube 3 carries, at its lower end, an end piece 20, on which is screwed a first support piece 22. This supports an axial rod 23 whose end is threaded , and onto which a second support piece 24 is screwed. A piece 25 forming a spacer maintains the distance between the pieces 22 and 24 at the appropriate value.
  • the rotary head 6 is interposed between the two support pieces 22 and 24, with the possibility of rotation about the axis xx ′. As can best be seen in FIG. 4, the head 6 carries, on the one hand, a tangential nozzle 7, consisting of a bent horizontal tube which opens out inside the internal cavity 26 of the head 6, and, on the other hand, the axis 11 of the rotor 10.
  • the rotor 10 is a hollow part, the shape of which is indicated in FIG. 5. It comprises two ejection nozzles 12, tangential, diametrically opposite, and its internal space communicates with that of head 6 thanks to longitudinal and transverse holes 27 of the shaft 11.
  • the respective rotational speeds of the head 6 around the axis xx ′ and of the rotor 10 around the axis yy ′ are not in a simple ratio. If, for example, the two speeds were equal, the points of impact of the two jets 13 on the wall of the container 2 would describe a fixed curve, and cleaning would be limited to the immediate surroundings of this curve.
  • the speed of rotation of the rotor 10 is notably higher than that of the head 6, so as to limit the effects of centrifugal force which tend to separate the jets 13 from the axis.
  • the rotary head 6 has a cylindrical surface which rotates, with very little play, inside a coaxial cylindrical surface of the support piece 22 or 24, and one of these cylindrical surfaces is hollowed out by a groove helical 28, 29 which opens, at one of its ends, into the interior cavity of the rotary head.
  • a groove helical 28, 29 which opens, at one of its ends, into the interior cavity of the rotary head.
  • One of these grooves has a step to the left, the other a step to the right, so that when the rotary head turns, under the effect of the force created by the jet 8, this groove acts in the same way as '' an Archimedes screw to return the liquid to the cavity.
  • the rotor also has helical grooves 30-31 cooperating with cylindrical surfaces of the rotary head, or vice versa, and which function in the same way.
  • FIGS. 6 to 8 relate to alternative embodiments of the support, the rotary head and the rotor, intended to obtain very reduced friction when the system is running.
  • the axial rod 23 visible in FIG. 3 is replaced by an axial metal tube 32, fitted into the support 20, emerging through one of its ends inside the latter, and pierced with radial holes 33 in its central part.
  • Two bearings 34 are screwed inside the rotary head 6 and fitted onto the tube 32, around which they can rotate.
  • Two metal washers 35 of suitable thickness are threaded onto the tube 32, one between the bearing 34 located at the top, in the figure, and the support 20, the other between the second bearing 34 and a stop 36 fixed on the tube 32, and which closes the latter while ensuring the maintenance of the rotary head.
  • the fixing of the rotor likewise calls upon a tube 39, which has holes 40 in its central part.
  • the tube 39 is fitted into the rotor 10 and rotates with it, its end opens into the internal cavity 41 of the rotor.
  • Two bearings 42 are screwed into the rotary head 6, they are coaxial and support the tube 40 while allowing its rotation.
  • Metal washers 43 are threaded onto the tube 39, one between the rotor 10 and the nearest bearing 42, the other between the second bearing 42 and a stop 44, fixed on the tube 40 and which ensures both closing this tube and holding the rotor in place.
  • Figure 8 is a section similar to Figure 6, of another variant.
  • An axial tube 50 extends the support 20. It is terminated by a stop 51, the outer surface of which is spherical, and pierced with radial holes 52.
  • the rotary head 6 is formed of two hollow shells in the form of a fraction of a sphere, assembled by screws 53.
  • Dynamic sealing bearings 54, 55 constituted by washers provided with spiral grooves, maintain the rotary head relative to the tube 50.
  • a lateral nozzle not shown, ensures the rotation of the rotary head 6.
  • Two rotors 10, arranged symmetrically are rotatably mounted in the rotary head 6.
  • a head 56 the outer surface of which is in the form of a portion of a sphere, and which is provided with nozzles 12, only one of which is shown, and a radial hollow rod 57, pierced a transverse hole 58 which opens into the interior void of the rotary head.
  • Ribs 59, carrying dynamic seals 60 hold the rotors 10 in the rotary head, coming to bear on an internal surface, facing the axis of the rotary head, of a bearing 61 with a C section open in the direction opposite to the axis of the rotary head.
  • a conduit 62 passes through each rotor 10 along its axis of symmetry, and places the interior of the ring 61 in communication with the atmosphere.
  • the rotor 10 is held in the ring 61 by the only centrifugal force which results from the rotation of the rotary head 6 and of the rotor 10 relative to the axis of the rotary head.
  • the outer surfaces of the stop 51 of the rotary head 6, and of the rotors 10 together form an almost complete sphere without protrusion, which reduces the risk of damaging the device and the container to be cleaned.
  • the axis xx ′ of the support tube 3 is vertical, the gasket 4 for supplying liquid being above the rotary head 6.
  • This arrangement is suitable for a container of sufficient large and provided with a drain hole, not shown, at its lower part. It is, of course, possible to adopt all kinds of different arrangements, and those skilled in the art will understand, for example, that, for receptacles without emptying orifice, the receptacle may be placed with its opening 18 directed towards the bottom, the whole of the device then being used in an inverted position relative to that of Figure 1, that is to say from top to bottom.
