Definitions

  • the invention relates to a removal system according to the preamble of claim 1.
  • Such a withdrawal system is from DE 10 2021 116 140 known.
  • This extraction system is used to fill and empty containers, especially drums, that are filled with liquid chemicals.
  • the extraction system includes an extraction head that can be attached to a dip tube of a container. By means of the removal head, liquid can be removed from the container via the dip tube or liquid can be supplied to the container.
  • the removal head can be fixed in a fastening position on the immersion tube by a displacement movement. The fastening position can be checked by means of an optical sensor, a target position of the immersion tube on the extraction head.
  • the extraction head can be screwed to the immersion tube.
  • the removal head has a liquid channel delimited by a wall, which is connected to the dip tube in the fastening position of the removal head, so that liquid can be removed from the container or fed to the container via the dip tube and the liquid channel.
  • the object of the invention is to provide a removal system of the type mentioned at the outset that has increased functionality and functional reliability.
  • the invention relates to a removal system for a container which has a dip tube and is designed to hold a liquid, with a removal head which can be fastened to the dip tube.
  • Liquid can be removed from the container via the dip tube and the removal head, or liquid can be supplied to the container.
  • the removal head has a liquid channel in which the liquid removed from or supplied to the container is guided.
  • An opening is provided in the wall delimiting the liquid channel, with the removal head being attached to the immersion tube, the opening being closed in such a way that it is secured against the ingress of gas or liquid, and with the opening no longer being closed when the removal head is detached from the immersion tube, so that gas enters the liquid channel via the opening.
  • the opening can have different shapes or cross-sections, such as. B. circular, oval, polygonal, slot-shaped.
  • the opening forms a bore. Without loss of generality, reference is made below to an opening in the form of a bore.
  • the gas that can get into the liquid channel via the hole that is not closed is formed in particular by air, but this is not mandatory. Without loss of generality, reference is made below to gas in the form of air.
  • the term closed generally includes a decoupling of the opening, i. H. drilling of gas or air, d. H. gas-tight separation of gas or air-carrying structures, in particular channel-like structures.
  • the closure means provided for this do not have to be arranged on the bore itself, but only have to be spatially assigned to it.
  • the dip tube forms a continuous channel with the liquid channel, via which liquid is removed from or supplied to the container.
  • the liquid channel runs coaxially to the dip tube in the longitudinal direction of the removal head and the dip tube.
  • the hole provided according to the invention in the wall of the liquid channel of the removal head is then closed, so that no air can penetrate from the outside into the liquid channel, which would impair the removal or supply of liquid.
  • the wall of the liquid channel advantageously forms a lateral surface of the liquid channel, which is surrounded by the immersion tube in the fastening position of the removal head.
  • the removal head is detached from the immersion tube, then while the removal head is still being released from its fastening position, i.e. while the liquid channel is still in the area of the immersion tube, in particular the liquid channel still protrudes into the dip tube, the closure of the bore is lifted.
  • the lifting of the closure of the hole is done solely by the displacement movement of the sampling head relative to the dip tube.
  • Such a displacement movement occurs both when the extraction head is fixed to the immersion tube with a pure displacement movement and when the extraction head is screwed tightly to the immersion tube, because a resulting relative displacement of the extraction head relative to the immersion tube is then also obtained.
  • At least one ventilation opening is provided in a wall of the dip tube, with at the dip tube attached extraction head the closed hole is decoupled from the ventilation opening.
  • the extraction head is detached from the immersion tube, air flows from the ventilation opening through the bore into the liquid channel.
  • a plurality of ventilation openings arranged at a distance from one another in the circumferential direction of the removal head can be provided.
  • Ventilation openings are advantageously provided for the purpose of discharging air introduced into and guided in the removal head, which serves to ventilate the immersion tube when it is emptied, to the outside.
  • the ventilation openings are used so that when the extraction head is detached from the dip tube, air is directed via at least one ventilation opening into the bore and then into the liquid channel, whereby the capillary effect of the liquid is eliminated and this prevents the extraction head from separating from the dip tube Liquid remains in the liquid channel.
  • the or each ventilation opening is decoupled from the bore, so that no air can get into the liquid channel via the bore, which would impede the liquid transfer through the liquid channel when the container is being filled or emptied.
  • a seal is advantageously provided on the outside of the wall delimiting the liquid channel, by means of which the bore is closed when the removal head is fastened to the immersion tube.
  • the bore can be closed and opened in a simple manner.
  • the seal is positioned relative to the bore such that when the sampling head is attached to the dip tube, the seal lies between the bore and the ventilation opening, as a result of which the seal prevents air from penetrating into the bore via the ventilation opening.
  • the seal is advantageously arranged just above the bore.
  • the seal lies outside the area between the ventilation opening and the bore.
  • the extraction head has a base body, with an upper section of the liquid channel running in the base body and with a lower section protruding downwards over the lower edge of the base body.
  • At least a part of the upper portion of the liquid channel is surrounded by a ventilation channel.
  • the dip tube When the dip tube is attached to the extraction head, its upper end surrounds the lower section of the liquid channel.
  • the bore and the seal are advantageously arranged in the lower section of the liquid channel.
  • the ventilation channel is expediently arranged concentrically with the liquid channel.
  • the extraction head attached to the immersion tube guides air introduced into the ventilation duct via a ventilation connection via the ventilation opening outward. This prevents air from getting from the ventilation channel into the liquid channel and the dip tube, which would impede the removal or filling processes.
  • FIG 1 shows schematically an embodiment of the removal system 1 according to the invention for transportable containers 2, which can be formed in particular from barrels or the like.
  • a liquid 3 is stored in the respective container 2 .
  • Liquids 3 stored in such containers 2 are, in particular, special liquid chemicals.
  • the removal system 1 includes a removal head 4 that can be attached to a dip tube 5 .
  • the dip tube 5 is mounted in a bung head 6 which sits in a container opening of the container 2 and is thus firmly connected to the container 2 .
  • the longitudinal axis of the immersion tube 5 runs in the vertical direction.
  • the removal head 4 is used to remove liquid 3 from the container 2. It can also be used to fill containers 2.
  • the removal head 4 has a liquid connection 4a at its upper end.
  • a line 7 leading to a pump 8 is connected to this liquid connection 4a.
  • the line 7 can be in the form of a hose.
  • the pump 8 is controlled by a control unit, not shown.
  • the removal head 4 is in figure 2 shown in a single representation.
  • the removal head 4 has a base body 4b forming a housing, at the upper end of which the liquid connection 4a is provided.
  • a check valve 9 connects to the lower end, which connects to the upper side of a liquid channel 10 .
  • the liquid channel 10 runs along the longitudinal axis of the removal head 4 and has a hollow-cylindrical shape.
  • the liquid channel 10 is delimited by a wall 11 .
  • An upper section of the liquid channel 10 of the removal head 4 runs in the base body 4b and is delimited there by a ventilation channel 12 from the rest of the base body 4b.
  • the ventilation channel 12 encloses the wall 11 of the liquid channel 10.
  • the ventilation channel 12 runs concentrically to the liquid channel 10.
  • a lower portion of the liquid passage 10 protrudes downward beyond the lower edge of the body 4b.
  • a thread 17 is provided at the lower end of the base body 4b of the removal head 4 with which the removal head 4 can be screwed tightly to the immersion tube 5 .
  • the immersion tube 5 is in figure 3 shown in a single representation.
  • the immersion tube 5 has a hollow-cylindrical tubular body 18 and a head part 19 on the upper side of the tubular body 18 .
  • the function of the removal system 1 with the removal head 4 on the dip tube 5 is in the figures 4a , 4b , 5a , 5b , 6a , 6b shown.
  • the figures 4a , 4b show the extraction head 4 screwed to the immersion ring 5.
  • the extraction head 4 is then in a fastening position, which can be secured with locking means and/or is monitored with a sensor system.
  • liquid 3 can be removed from the container 2 or fed to the container 2 via the immersion tube 5 and the liquid channel 10 of the removal head 4, which adjoin one another in a coaxial manner and form a common channel.
  • the channel is accordingly completely filled with liquid 3 for the discharge or introduction of liquid 3 .
  • the seal 16 is arranged between the ventilation openings 20 and the bore 15 in the fastening position.
  • the bore 15 is thus closed by the seal 16. Accordingly, air 14 which is supplied to the ventilation channel 12 via the ventilation connection 13 is discharged via the ventilation opening 20 without this air 14 reaching the bore 15, so that no air 14 can reach the liquid channel 10 either.
  • FIGS. 5a , 5b show the situation when the removal head 4 is detached from the immersion tube 5 by unscrewing the removal head 4 from the immersion tube 5.
  • the removal head 4 is only slightly released from the fastening position, ie the removal head 4 is still mounted on the dip tube 5 so that the liquid channel 10 with the dip tube 5 still forms a continuous channel to the line 7 of liquid 3 .
  • the penetration of the air bubbles 14a prevents liquid 3 from adhering to the wall 11 of the liquid channel 10 as a result of capillary action.
  • the liquid 3 dissolves so quickly and completely from the wall 11, so that after a short time, as in the Figures 6a , 6b shown, the entire liquid 3 is discharged not only from the dip tube 5, but also completely from the liquid channel 10, before the removal head 4 is detached from the dip tube 5.
