Abstract
Device for filling a receptacle (R) by lowering it onto a needle (5) which pierces it. The portions of the installation adjacent to the bottom of the receptacle (R), which could be polluted by ill-timed projections of liquid from the needle, are washed and dried by nozzles (27, 28, 29) for washing the zones potentially reached by the projections, as well as the needle (5) itself, this washing and drying being followed by drying by suction orifices (38).
Claims10
Device for filling a receptacle comprising:
- a filling liquid elevator ended by a needle for piercing a bottom of the receptacle;
- a sheath having a bottom constituted by a wall comprising an opening in front of the needle and mobile towards the needle and being connected to a network of pipes equipped with pneumatic means for displacing the receptacle;
- and a cage situated in the sheath and disposed so as to suspend the receptacle slightly above the bottom of the sheath, wherein the sheath is equipped with nozzles for sprinkling washing liquid towards the bottom of the receptacle suspended in the cage and towards an internal face of the wall of the sheath, said internal face facing the receptacle and defining a recess at the bottom of the sheath, and some of the nozzles are oriented in such a way so as to sprinkle the internal face of the wall of the sheath obliquely and produce a vortex of the washing liquid in the recess.
Filling device according to caim 1, wherein some of the nozzles are orientated in such a way so as to sprinkle the bottom of the receptacle obliquely and produce a rebounding of the washing liquid from the bottom of the receptacle towards the internal face of the bottom of the sheath.
