Definitions

  • the invention relates to a pressure vessel for spraying a liquid with a piston pump which can be actuated from the outside by piston strokes and is arranged in the interior of the pressure vessel to build up an increased pressure in the interior of the container and which has a pump cylinder mounted on the container and projecting into the interior of the vessel.
  • Such pressure vessels are known from European laid-open specification 268 921 A2, German laid-open specification 34 08 015 and German utility model 23 20 572.
  • pressure vessels are used, for example, to spray a decontamination liquid, the pressure required for the spraying being generated in the pressure vessels on the spot by actuating the piston pump.
  • a pressure container of the type described in the introduction in that the piston pump is mounted on the container such that it can be rotated about its longitudinal axis, that a drive for rotating the pump cylinder is arranged on the outside of the container and that the pump cylinder rotates into the position of the pump cylinder Liquid-projecting mixing elements. So the entire pump will additionally used as a drive for mixing elements with which the necessary mixing takes place inside the closed container by turning the pump.
  • the drive is a hand crank, but in other cases the drive could also be carried out with the aid of an attached electric motor or via a drive belt coupled to a pulley.
  • the pump cylinder itself carries the mixing elements. This enables a particularly simple construction.
  • the pump cylinder can carry this substantially radially projecting mixing blade which surrounds the screw shape.
  • These helical mixing blades convey liquid from the bottom of the pressure vessel upwards, so that it is ensured that chemicals accumulating at the bottom of the vessel are mixed evenly into the rest of the liquid and that when the container is emptied, an even mixture is released via the underside and not liquid that would accumulate on the bottom of the container without these mixing blades.
  • annular mixing elements are held on the pump cylinder concentrically to the axis of rotation of the latter at the lower end.
  • mixing can also be carried out with a container under pressure, since the rotary feedthrough for the pump cylinder must of course be pressure-tight. It is therefore possible, even after a brief interruption in the spraying, to mix briefly again before the next spraying operation, in order to be sure that a homogeneous mixture is sprayed.
  • the driving engagement is preferably in the form of a plug-in coupling.
  • the pump cylinder is mounted in the pressure vessel so as to be displaceable in the axial direction, wherein the entrainment engagement exists at least in a first position pulled out of the pressure vessel, and when the pump cylinder is sealed against the pressure vessel in a second position pushed into the pressure vessel.
  • the mixing takes place with the pump cylinder pulled out, that is to say in a state in which the pressure vessel has not yet been sealed.
  • the pump cylinder can be moved into the sealed second position, in which the pressure can then be built up.
  • the pump cylinder is supported in the first position by a removable stop which prevents the pump cylinder from being displaced into the second position.
  • This stop can preferably be formed by at least one holder which can be pivoted into the displacement path of the pump cylinder and which can be designed, for example, in a bow-shaped manner.
  • the pressure vessel 1 shown in FIG. 1 has a central opening 2 on its upper side and a likewise central opening 3 on its lower side. On the underside of the opening 3 is connected to a drain line shown only in dash-dotted lines, in the opening 2 at the top, which is designed as a filling opening and is provided for this purpose with a funnel-shaped extension 4, a piston pump 5 can be used sealed .
  • This piston pump 5 comprises a pump cylinder which extends to the underside of the pressure vessel 1 and which can be fixed axially immovably and sealed in the upper opening 2 by means of a sealing collar 7 surrounding it.
  • the sealing collar 7 enables the pump cylinder 6 to rotate about its longitudinal axis.
  • a piston 9 which can be moved up and down periodically via a rod 8, as is generally known from air pumps.
  • the piston 9 can over the rod 8 can be moved up and down by means of a handle 10 which is arranged on the outside of the pressure vessel 1. In this way, the pressure inside the pressure vessel can be increased to such an extent that liquid in the vessel can be released under pressure through the lower opening.
  • the handle 10 is designed as a crank and is connected in a rotationally fixed manner to the pump cylinder 6 via radially projecting pins 11 of the pump cylinder 6 in the pushed-in position, so that when the crank-shaped handle 10 is rotated, the entire pump in the opening 2 is rotated about the longitudinal axis of the pump.
  • the mixing blades 12 stir the liquid in the pressure vessel and mix the components of this liquid uniformly.
  • This mixture is supported by the special shape of the mixing blades, which convey liquid components from the bottom to the top of the pressure vessel.
  • the mixing ring 13 ensures that no liquid remains stationary on the underside of the pressure vessel, so that when liquid is drained through the lower opening 3, a homogeneous liquid mixture is always dispensed if the liquid has previously been stirred in the manner described.
  • the piston pump thus fulfills a double function: it can be used to generate an increased pressure inside the container in a conventional manner and, at the same time, this piston pump 5 can be rotated to mix the liquid components evenly when the container is closed and without the need for a separate tool to produce any desired emulsions.
  • the mixing blades can also have other configurations, for example they can have greater radial distances from the pump cylinder than is the case in the exemplary embodiment described and shown in the drawing.
  • a mixing element 15 is mounted in the pressure vessel so as to be rotatable about its longitudinal axis, which in the exemplary embodiment shown consists of three vertical webs 16, each offset by 120 degrees from one another exists, which are each connected to a bearing bush 18 or 19 via corresponding radial arms 17. These bearing bushes are mounted on bearings that are fixed to the pressure vessel.
  • the pump cylinder 6 is mounted on the pressure vessel so as to be axially displaceable, for example passing through the upper bearing bush 18.
  • the lower end carries the Pump cylinder a sleeve-shaped driver 20, which has a slot-shaped opening 21 on its lower end face.
  • the mixing element 15 is also rotated accordingly.
  • the plug-in coupling produces this entrainment engagement even when the pump cylinder has a different axial position, ie the pump cylinder can be displaced in the axial direction with respect to the mixing element without the entrainment engagement being released.
  • the pump cylinder is pulled very far out of the pressure vessel, the entrainment intervention can be released. It is therefore possible to pull the pump cylinder completely out of the pressure container, for example for cleaning purposes.
  • the pump cylinder can be shifted between two positions in the area in which the entrainment engagement is maintained, namely between a first position slightly pulled out of the pressure container (shown in FIG. 2) and a second position completely pushed into the pressure container.
  • the pump cylinder 6 In the first position, the pump cylinder 6 can be fixed by bow-shaped holders 23 which are pivotably mounted on the outside of the pressure vessel and can be pivoted into the displacement path of the pump cylinder such that the pump cylinder is supported on these holders 23 by a collar 24.
  • the pressure vessel is in this position not tightly closed.
  • the entrainment engagement with the mixing element 15 is made so that it is possible in this position to turn the mixing element 15 by rotating the handle 10 via the pump cylinder and thus to produce the desired mixture.
  • the holders 23 can be swiveled out again (shown with dash-dotted lines in FIG. 2). It is then possible to bring the pump cylinder into the inserted, second position, in which it can be screwed into the pressure vessel by means of a suitable threaded connection 25.
  • This screw connection is pressure-tight, so that the pressure vessel is thereby closed pressure-tight.
  • the pump cylinder can no longer be rotated relative to the pressure vessel, so mixing can no longer take place.
  • this also means that a pressure-tight rotating union can be dispensed with, since in the sealed state the pump cylinder can no longer be rotated relative to the pressure vessel.
