Definitions

  • the present invention relates to washing the external surface of cylindrical objects, in particular but not exclusively bottles of liquefied petroleum gas or LPG.
  • the washing techniques currently used start from a continuous tunnel type design, in which the objects to be washed pass continuously.
  • the tunnel then generally comprises several successive treatment zones, but all these zones are arranged in the single casing of the tunnel.
  • the installations have a large dimension making their installation sometimes very difficult, and imply a high energy cost due to the continuous watering of the conveyed objects.
  • the design in successive ramps for the spraying means does not allow a homogeneous and regular projection on the objects. It is indeed easy to understand that the distances of the jets sprayed from the lateral ramps differ according to the zones concerned of the cylindrical external surface of the objects to be washed, which induces a maximum action for short jets, and minimal or even zero for long jets (the generator zones located on the central axis scrolling are practically not affected): this then requires oversizing the equipment, which is more expensive.
  • Continuous washing and drying machines have also been proposed, based on the same principle of continuous tunnel, and also using transverse spraying ramps produced in the form of a rectangular frame.
  • This technique may be suitable for a decontamination treatment of cans, but it is unthinkable for washing in series, since it is necessary to wash the cans one by one, by actuating the associated lifting system each time.
  • this technique remains limited to very specific types of cylindrical objects, and in particular would be difficult to transpose to washing LPG bottles.
  • the object of the invention is to propose a method and a device making it possible to carry out an effective washing of the external surface of cylindrical objects, in particular LPG bottles (it could naturally be other objects, for example metallic food cans), the process can also be completely automated.
  • the invention also aims to implement a washing process with a projection of liquids which is both homogeneous and regular, on the walls of the object.
  • the object of the invention is also to implement an easy implantation washing process, thanks to a reduced dimensioning, and to the absence of bulky equipment and / or requiring a significant source of energy.
  • the invention finally aims to implement a washing process which can avoid having to provide a recycling system, thanks to a low consumption of water which can simply be discharged into the wastewater network after decantation.
  • the unitary object is rinsed at the rinsing station by spraying water under high pressure, by actuating a rotary spraying means, said object being again held stationary in a position such that its vertical axis substantially coincides with the axis of said means of spraying.
  • the unitary object is transferred, downstream of the spraying station and upstream of the rinsing station, to a brushing station provided upstream of the rinsing station, where a rotary brushing means is actuated, said object being kept fixed in a position such that its vertical axis coincides substantially with the axis of said brushing means, the transfer of the unitary object upstream and downstream of the brushing station being done in the open air.

  • the spraying of the detergent agent on the unit object located at the spraying station is carried out by rotating the rotary spraying means at constant speed, and / or by rotating the spraying means over a full revolution.

  • the drying of the unitary object by blowing air located at the drying station is carried out in two stages, with a pre-drying of the upper part of said object during transfer, followed by drying properly says during which the unitary object is driven in rotation around its axis.
  • the unitary object is maintained, during the actual drying, between a rotary turntable and an upper coaxial centering head previously lowered vertically to be in contact with said object; in particular, the upper centering head is lowered on the unitary object before the latter rests on the rotating drive plate, after which said head and said plate are raised in synchronism.
  • two unitary objects can be simultaneously at the drying station, the upstream object being awaiting transfer for a pre-drying and the downstream object undergoing proper drying; in particular, the air blowing is carried out alternately on one or the other unitary object, using blowing means permanently actuated to carry out either a pre-drying, or a drying proper.
