Definitions

  • the present invention relates to a device for cleaning delivery units for flowable media, which forms a fluidic cleaning circuit in which a detergent tank and at least one pumping unit to be cleaned flows through a cleaning agent, wherein at least one of the pumping units to be cleaned circulates the cleaning agent in the cleaning circuit ,
  • Delivery units are used in numerous areas of trade and industry. In principle, practically liquids of very different viscosity can be conveyed, which are to be transferred from one container to another.
  • delivery units may be equipped with pump lances and thus protrude into a barrel, wherein the delivery unit removes the fluid contained in the barrel on the pump lance and further.
  • the present invention the object of the invention to provide a device for cleaning delivery units for flowable media, which can be used very easily and effectively, to keep the associated expenses on the part of the user as low as possible.
  • a device for cleaning delivery units for flowable media initially forms a fluidic cleaning circuit in which a cleaning agent is pumped in circulation between a detergent tank and the delivery unit to be cleaned.
  • the cleaning agent is also a flowable Medium that passes everywhere due to the passage through the delivery unit, where also the promoted during operation of the delivery unit flowable media go.
  • the detergent may be simple water, but the water may also be mixed with effective substances such as soaps or other chemical, disinfecting or solvent-containing substances.
  • other hydrocarbon-based cleaners such as alcohols, benzenes and the like may be used more or form the basis for a cleaning agent.
  • the detergent tank is filled with the detergent and then started the circulation in the cleaning cycle thus formed.
  • the circulation takes place here by means of the pumping unit itself to be cleaned, which promotes the originating from the detergent tank cleaning agent by itself and returns to the detergent tank again.
  • the cleaning agent can still be exchanged for a means for rinsing, which also largely rinses away the substances of the cleaning agent. It is also possible to leave the delivery unit with the cleaning agent in it approximately overnight, between the rinsing step and the rinsing step, so that the substances of the cleaning agent can act. Also, the pump can be left in the rinse step overnight to eliminate even heavy soiling.
  • a metering pump has an inlet and a drain, which can be connected directly to the detergent tank, so that the metering pump promotes as a pumping unit directly from the detergent tank into the detergent tank.
  • the inlet is then connected via a feed line with a drain of the detergent tank and the drain via a drain line with an inlet of the detergent tank.
  • the delivery unit is a container pump with a pump lance
  • the device must look somewhat different.
  • the pump lance directly into the detergent tank and to design this purpose as a dip tank.
  • the container pump will pump detergent out of the dip tank and feed it back directly through an inlet.
  • the intended for the cleaning of the container pump dip tank can be formed separately from the detergent tank.
  • the cleaning circuit provides a dip tank having an upper side insertion opening for introducing the pump lance of the tank pump. The container pump then sucks the detergent from the dip tank and conveys it back into the detergent tank, from where it can flow back into the dip tank via a feed line.
  • the dip tank can have a taper in its upper area, ie around the insertion opening, so that the pump action in the upper area becomes stronger and there the flow caused by the pump flows faster. This additionally improves the cleaning effect.
  • the dip tank may further comprise an insertion funnel at its upper insertion opening, which widens upwards and is simplified by way of positioning the pump lance of a container pump to be connected to the dip tank.
  • an insertion funnel may catch any of the delivery unit dripping medium and into the dip tank run in, so that no contamination around the device around.
  • a drip protection plate can be attached to this insertion funnel, which, for example, can be configured as a gutter and can be detachably connected to the upper edge of the insertion funnel by means of clamps, plugs, screws and the like. While the introducer funnel provides more local drip protection, the drip guard can cover the full path from a container to the dip tank and trap any falling drops and discharge into the introducer funnel.
  • the drip guard plate may indeed be placed on the insertion funnel and the container in which the container pump was previously operated, but in order to ensure a run-in of the dripping liquid in the insertion funnel the drip guard plate at least horizontally, preferably at an angle between 0 ° and 10 °, be inclined down to the upper edge of the insertion funnel and more preferably protrude cantilevered from this upper edge.
  • a fixing device may be provided with which the pump lance and thus the container pump connected to the pump lance are fixed relative to the dip tank.
  • Such a fixing device may be formed from a plurality of distributed over the circumference of the outer wall of the dip tank clamping screws which can be screwed through the outer wall by means of each cut into the outer wall or this superior thread to the center of the insertion. They then hit the pump lance and fix it from several sides until the pump lance is immovable.
  • the clamping screws can be provided with terminal handwheels be able to do a fixation with the bare hand, so tool-free.
  • An essential aspect of the invention is a cleaning of delivery units from the inside by the detergent is pumped through the delivery units.
  • an external cleaning especially in the area of its pump lance makes sense, since it always protrudes in operation at least partially with its outside in the medium to be conveyed.
  • the outer wall of the dip tank preferably in the region of the introduction opening, may be assigned a plurality of supply lines, via which cleaning agent is introduced from the dip tank or from the detergent tank into the dip tank, injected with advantage. At the moment of immersion of the pump lance this is injected and thus externally freed of dirt while it is introduced into the dip tank.
  • a sleeve chamber may be formed around the insertion opening, on whose inner wall one or more, preferably evenly over the inner circumference of the inner wall of the sleeve chamber, have inlet openings in the direction of the pump lance.
  • auxiliary pump can support the pumping unit to be cleaned or work only in alternation with this.
  • the feed line or alternatively or additionally the drain line to a floor drain which preferably in a geodesic is formed lowest point and allows emptying of the cleaning circuit due to gravity.
  • a drain valve in this case prevents the inadvertent loss of detergent and can therefore switch back and forth between an open and a closed position.
  • the floor drain can additionally be assigned a filter arrangement with the aid of which substances of the cleaning agent can be separated and / or neutralized. It is thus prevented that contaminants contained in the detergent escape and constitute an environmental toxin.
  • the cleaning circuit may also be associated with a heating element.
  • a heating element which may be configured as a water heater or the like, the temperature of the cleaning agent can be increased in order to bring thermal reaction forces for improved cleaning effect used.
  • the cleaning agent is pumped continuously in a circle, so that there is approximately no change in the amount of cleaning agent during a cleaning process.
  • the detergent tank or optionally the dip tank may have a filling opening to which a filling line to a cleaning agent source such as a water pipe or a detergent container, connected.
  • the cleaning agent can preferably additionally be metered with cleaning-active additives, for example by means of a metering pump assigned to the filling line, preferably a proportional metering.
  • the entire cleaning circuit works in a simple arrangement initially with a single delivery unit. However, it is also possible to connect a plurality of delivery units fluidly behind one another, so that the cleaning agent flows through the individual delivery units in succession. In this case, however, only one of the delivery units should be actively operated be, while the other delivery units are at most driven by the flowing detergent. If several delivery units were operated at the same time, pressure could build up between several delivery units of different delivery rates, which could damage the delivery units.
  • the cleaning circuit is arranged with its elements as a mobile construction on a transport vehicle, such as a handcart.
  • a transport vehicle such as a handcart.
  • FIG. 1 shows a handcart 26, which is mounted on wheels and thus designed mobile.
  • This handcart 26 is placed in close proximity to a barrel 25, from which just a delivery unit 1 has been removed with a pump lance 7 and inserted into a dip tank 8.
  • the delivery unit 1 was previously used in the barrel 25 as a container pump to bring out the content of the barrel 25 and supply its destination. Now that the delivery unit 1 is no longer needed in the barrel 25, the delivery unit 1 is pulled out with its pump lance 7 from the barrel 25 and introduced into the dip tank 8 for cleaning.
  • the dip tank 8 has an insertion funnel 10.
  • a drip guard plate 24 is releasably secured by jamming or screwing on the edge of the insertion funnel, so that the pump lance 7 when pulling out of the barrel 25 and spending in the dip tank 8 leaves no impurities.
  • the pump lance 7 is always located above the barrel 25, the gutter-shaped drip guard plate 24 or the insertion funnel 10 until it has been introduced through an insertion opening 9 in the middle of the insertion funnel 10 into the interior of the dip tank 8.
  • a detergent tank 4 With arranged on the trolley is a detergent tank 4, which sprays 8 cleaning agent on the pump lance via an auxiliary pump 16 through a sleeve ring 14 of the dip tank, as later FIG. 2 described. Also, the detergent tank 4 is connected via a near-bottom inlet / outlet line 5, 6 with the dip tank 8 and a drain line 6 with a flow of the delivery unit 1. The reproached in the detergent tank 4 detergent is then introduced during operation of the described arrangement from the detergent tank 4 via the supply lines 5 in the dip tank 8 and there clean the pump lance 7 from the outside.
  • the delivery unit 1 is operated for this purpose, so that in the Submersible container 8 contained cleaning agent, for example, water with a cleaning additive sucked at the free end of the pump lance 7 and pumped through the pump lance 7 and the delivery unit 1 through back into the detergent tank. Due to the flow through the delivery unit 1 and the flushing of the immersed parts is carried out a cleaning of the delivery unit 1 from the inside and from the outside.
  • cleaning agent for example, water with a cleaning additive sucked at the free end of the pump lance 7 and pumped through the pump lance 7 and the delivery unit 1 through back into the detergent tank. Due to the flow through the delivery unit 1 and the flushing of the immersed parts is carried out a cleaning of the delivery unit 1 from the inside and from the outside.
  • an auxiliary tank 22 is further arranged on the hand truck 26, in which the cleaning additive is kept.
  • a proportional dosing 21 which is also connected to a detergent source 23, for example a water pipe or another tank. Proportional dosing ensures that an exact mixture of the desired cleaning agent is available and, even in the case of pure refilling, the ratio between cleaning agent and cleaning additive remains the same.
  • a floor drain 17 is provided, which is arranged in a floor near inlet / outlet pipe between the detergent tank 4 and the dip tank 8.
  • the drain valve 18 By opening the drain valve 18, both the detergent tank 4 and the dip tank 8 can be completely emptied due to gravity, which can be done depending on the application, recently promoted medium and detergent used and cleaning additives in a container or in the sewer.
  • FIG. 2 shows as a detail the FIG. 1 the region of the insertion opening 9 of the dip tank 8. This is associated with a collar ring 14 which surrounds the insertion opening 9.
  • an auxiliary pump 16 cleaning agent from the detergent tank 4 is conveyed during the introduction of the pump lance 7 of the pumping unit to be cleaned in the dip tank 8, which first fills a cavity in the sleeve ring 14 and then via inlet openings 15 on the inside of the sleeve ring 14 on the pump lance 7 sprays.
  • the pump lance is clamped by means of clamping screws 13, which are arranged on a fixing device 12 and distributed over the circumference of the neck of the dip tank, so that during operation of the delivery unit 1, this does not swing up to strong movements, but is held securely.
  • FIG. 3 shows a schematic arrangement of the elements of the cleaning circuit in the case of simultaneous cleaning of three to be cleaned delivery units 1, 2 and 3. These are fluidly connected in series, so that of a detergent tank 4 via a supply line 5 brought up cleaning agent first the delivery unit 1, then the delivery unit 2 and finally the delivery unit 3 passes through before it is conveyed back via a drain line 6 to the detergent tank 4.
  • a detergent tank 4 via a supply line 5 brought up cleaning agent first the delivery unit 1, then the delivery unit 2 and finally the delivery unit 3 passes through before it is conveyed back via a drain line 6 to the detergent tank 4.
  • the other two passive delivery units 2 and 3 which are driven by the active delivery unit 1.
