Bei Reinigungsverfahren, bei denen die Reinigungsflüssigkeit nicht wiederverwendet wird, wird mit dem erfindungsgemäßen Verfahren weiterhin dadurch noch eine beträchtliche Menge an Reinigungsflüssigkeit eingespart. Mit der Erfindung ist ein Verfahren zur Reinigung mit Reinigungsstrahlen der eingangs genannten Art geschaffen, bei dem Energie eingespart und die Dauer des Reinigungsprogrammes verkürzt werden kann.With the inventive method of increasing the pulse of the drops of a cleaning jet inevitably increases the intensity of the mechanical Abtrag on the surface of the material to be cleaned, ie, the effectiveness of the cleaning jet improves, whereby, as explained above, a sufficient cleaning result mainly by a sufficient Duration of loading of the material to be cleaned and thereby taking place over the period mechanical removal of dirt on the goods to be cleaned is achieved, the duration of the cleaning program shortened and thus less energy to promote the cleaning fluid is needed. In cleaning processes in which the cleaning liquid is not reused, the method according to the invention still saves a considerable amount of cleaning liquid. With the invention, a method for cleaning with cleaning jets of the type mentioned is created, can be saved in the energy and the duration of the cleaning program can be shortened.

In der nachfolgenden Figurenbeschreibung werden gleiche Teile mit gleichen Bezugszeichen benannt.In the following description of the figures, the same parts are designated by the same reference numerals.

In den im folgenden Ausführungsbeispielen wird das erfindungsgemäße Verfahren zur Reinigung mit Reinigungsstrahlen an einer Vorrichtung zur Förderung von Flüssigkeiten nach dem Taktpropfenverfahren gezeigt und beschrieben.In the following exemplary embodiments, the method according to the invention for cleaning with cleaning jets is shown and described on a device for conveying liquids by the Taktpropfenverfahren.

Eine Vorrichtung 1 zur Förderung von Flüssigkeiten nach dem Taktpropfenverfahren in den gezeigten und beschriebenen Ausführungsbeispielen weist eine Anordnung 10 auf, in der die Flüssigkeit durch ein unter Druck stehendes Gas beaufschlagt wird, wobei die Flüssigkeit in der Anordnung 10 durch das Gas mit einem Druck beaufschlagt wird, der zwischen zwei Druckniveaus abwechselnd so verändert wird, daß bei einem niedrigen Druckniveau die Flüssigkeit nachfließt und durch Anlegen des höheren Druckniveaus in die gewünschte Förderrichtung gefördert wird. Das Gas wird in den gezeigten Ausführungsbeispielen mittels eines Verdichters 2 unter Druck gestellt. An den Verdichter 2 in Strömungsrichtung des Gases nach dem Verdichter 2, das heißt an einem Druckausgang 3 des Verdichters 2, ist ein Druckbehälter 4 angeschlossen, in den das Gas eingeleitet und bevorratet wird.An apparatus 1 for conveying liquids by the clocking method in the embodiments shown and described comprises an arrangement 10 in which the liquid is acted upon by a pressurized gas, wherein the liquid in the assembly 10 is pressurized by the gas which is alternately changed between two pressure levels so that at a low pressure level, the liquid flows back and is conveyed by applying the higher pressure level in the desired conveying direction. The gas is pressurized in the embodiments shown by means of a compressor 2. To the compressor 2 in the flow direction of the gas after the compressor 2, that is, at a pressure outlet 3 of the compressor 2, a pressure vessel 4 is connected, in which the gas is introduced and stored.

Weiterhin weist die Anordnung 10 einen mit einem Flüssigkeitsbehälter 9 flüssigkeitsleitend verbundenen Druckraum 11 auf. In den Druckraum 11 wird das Gas, gesteuert durch ein Ventil 5, eingeleitet. Dieses Ventil 5 zur Steuerung der Einleitung des Gases in den Druckraum 11 ist in einer Verbindungsleitung 21 zwischen dem Druckbehälter 4 und einem Eintritt 20 des Gases in den Druckraum 11 angeordnet. Mit dem Druckraum 11 und dem Flüssigkeitsbehälter 9 ist eine Flüssigkeitsableitung 12 flüssigkeitsleitend verbunden. Eine Flüssigkeitsleitung 13 ist von dem Flüssigkeitsbehälter 9 bis zur Flüssigkeitsableitung 12 fortgesetzt und weist eine Abzweigung 14 zu dem Druckraum 11 auf. Zwischen dem Flüssigkeitsbehälter 9 und dem Druckraum 11 ist ein Ventil 15 zum Öffnen und Schließen der Verbindung zwischen dem Flüssigkeitsbehälter 9 und dem Druckraum 11 angeordnet, das im Ausführungsbeispiel ein Rückschlagventil mit kugelförmigem Schließkörper ist, das einen Flüssigkeitsauslaß aus dem Flüssigkeitsbehälter 9 bei Auftreten einer gegen den Flüssigkeitsbehälter 9 gerichteten Strömung verschließt. Zwischen dem Druckraum 11 und der Flüssigkeitsableitung 12 ist ein Ventil 16 zum Öffnen und Schließen der Flüssigkeitsableitung 12 angeordnet, das im Ausführungsbeispiel ein Rückschlagventil mit kugelförmigem Schließkörper ist, das die Flüssigkeitsableitung 12 bei Auftreten einer gegen den Flüssigkeitsbehälter 9 oder gegen den Druckraum 11 gerichteten Strömung verschließt. Der Druckraum 11 weist einen weiteren mit einem Ventil 17 gesteuerten Eingang 18 auf, an den eine Entlüftungsleitung 19 angeschlossen ist. Der Eintritt 20 des Gases in den Druckraum 11 in Gebrauchslage, d.h. aus frontaler Sicht auf die Figuren 1 und 2, oben und der Eintritt der Flüssigkeitsleitung 13, d.h. die Abzweigung 14, unten angeordnet ist.Furthermore, the arrangement 10 has a fluid-connected to a liquid container 9 pressure chamber 11. In the pressure chamber 11, the gas, controlled by a valve 5, is initiated. This valve 5 for controlling the introduction of the gas into the pressure chamber 11 is in a connecting line 21 between the pressure vessel 4 and an inlet 20 of the gas in the pressure chamber 11 is arranged. With the pressure chamber 11 and the liquid container 9, a liquid discharge 12 is fluidly connected. A liquid line 13 is continued from the liquid container 9 to the liquid discharge 12 and has a branch 14 to the pressure chamber 11. Between the liquid container 9 and the pressure chamber 11, a valve 15 for opening and closing the connection between the liquid container 9 and the pressure chamber 11 is arranged, which is a check valve with spherical closing body in the embodiment, the liquid outlet from the liquid container 9 in the occurrence of a against the Liquid container 9 directed flow closes. Between the pressure chamber 11 and the liquid discharge 12, a valve 16 for opening and closing the liquid discharge 12 is arranged, which is a check valve with spherical closing body in the embodiment, which closes the liquid discharge 12 upon the occurrence of a directed against the liquid container 9 or against the pressure chamber 11 flow , The pressure chamber 11 has another with a valve 17 controlled input 18 to which a vent line 19 is connected. The inlet 20 of the gas into the pressure chamber 11 in the position of use, ie from a frontal view of Figures 1 and 2, above and the inlet of the liquid line 13, ie the branch 14, is arranged below.

In der in Fig. 1 und 2 gezeigten Ausführungsform der Vorrichtung 1 zur Förderung von Flüssigkeiten nach dem Taktpropfenverfahren weist die Anordnung 10 eine Verbindung 23 zwischen dem Druckraum 11 und einer Saugleitung 7 des Verdichters 2 auf, wobei die Saugleitung 7 des Verdichters 2 in Strömungsrichtung des Gases nach der Abzweigung für die Verbindung 23 mit dem Ventil 17 des weiteren mit einem Ventil 17 gesteuerten Eingangs 20 des Druckraumes 11 ein weiteres Ventil 8 zum Öffnen oder Schließen der Saugleitung 7 gegenüber der Umgebung aufweist.In the embodiment shown in FIGS. 1 and 2 of the device 1 for the delivery of liquids by the Taktpropfenverfahren, the assembly 10 has a connection 23 between the pressure chamber 11 and a suction line 7 of the compressor 2, wherein the suction line 7 of the compressor 2 in the flow direction of the Gas after the branch for the connection 23 with the valve 17 of the further 17 with a valve 17 controlled input 20 of the pressure chamber 11 has a further valve 8 for opening or closing the suction pipe 7 from the environment.

In der in Fig. 1 und 2 gezeigten Ausführungsform der Vorrichtung 1 zur Förderung von Flüssigkeiten nach dem Taktpropfenverfahren wird, wie oben schon erläutert, in der Anordnung 10 die Flüssigkeit durch das Gas mit einem Druck beaufschlagt, der zwischen zwei Druckniveaus abwechselnd so verändert wird, daß bei einem niedrigen Druckniveau die Flüssigkeit nachfließt und durch Anlegen des höheren Druckniveaus in die gewünschte Förderrichtung gefördert wird., wobei in der Anordnung 10 bei dem niedrigen Druckniveau, ein Unterdruck herrscht, so daß die Flüssigkeit angesaugt wird und beim Anlegen des höheren Druckniveaus ein Überdruck herrscht.In the embodiment shown in FIGS. 1 and 2 of the device 1 for the conveyance of liquids by the stroke plunger method, as already explained above, in the arrangement 10, the liquid is pressurized by the gas with a pressure alternately changed between two pressure levels. that at a low pressure level, the liquid flows back and is conveyed by applying the higher pressure level in the desired conveying direction, wherein in the assembly 10 at the low pressure level, a negative pressure prevails, so that the liquid is sucked in and there is an overpressure when the higher pressure level is applied.

Alternativ zu der oben angeführten Verbindung mit einer Saugleitung 7 des Verdichters 2 ist es natürlich auch möglich den benötigten Unterdruck mit einem zusätzlichen Verdichter zu erzeugen und diesen an die Verbindung 23 anzuschließen.As an alternative to the above-mentioned connection with a suction line 7 of the compressor 2, it is of course also possible to generate the required negative pressure with an additional compressor and connect it to the connection 23.

Zur Durchführung des erfindungsgemäßen Verfahrens zur Reinigung mit Reinigungsstrahlen weist die Anordnung 10 eine Verbindung 22 zwischen der Flüssigkeitsableitung 12 und dem Druckbehälter 4 auf. In der Verbindung 22 ist ein weiteres Ventil 6 zur Steuerung der Einleitung des Gases in die Flüssigkeitsableitung 12 angeordnet.To carry out the method according to the invention for cleaning with cleaning jets, the arrangement 10 has a connection 22 between the liquid discharge 12 and the pressure vessel 4. In the connection 22, a further valve 6 for controlling the introduction of the gas is arranged in the liquid discharge 12.

Die Förderung von Flüssigkeit nach dem Taktpropfenverfahren unter Einfügung des erfindungsgemäßen Verfahrens zur Reinigung mit Reinigungsstrahlen wird in dem in Fig. 1 und 2 gezeigten Ausführungsbeispiel wie folgt ausgeführt:The conveyance of liquid by the cyclic pitch method incorporating the method according to the invention for cleaning with cleaning jets is carried out in the embodiment shown in FIGS. 1 and 2 as follows:

Die Ventile 5, 6, 8 und 16 sind anfänglich geschlossen, die Ventile 15 und 17 sind geöffnet. Die Verbindung zwischen dem Flüssigkeitsbehälter 9 und dem Druckraum 11 ist unter dem Flüssigkeitsniveau N1 des Flüssigkeitsbehälters 9 angeordnet, so daß sich die Flüssigkeit in dem Flüssigkeitsbehälter 9 auf das Flüssigkeitsniveau N1 und in dem Druckraum 11 aufgrund der weiter unten beschriebenen Saugfunktion des Unterdruckes auf das wesentlich höhere Flüssigkeitsniveau N1' erstreckt. Durch Öffnen des Ventils 5 wird das unter einem Überdruck stehende Gas in den Druckraum 11 eingeleitet, wodurch die Flüssigkeit bis zu einem unteren Flüssigkeitsniveau N2 verdrängt wird. Dabei wird das Ventil 15 geschlossen und das Ventil 16 geöffnet, so daß die Flüssigkeit weiter in die Flüssigkeitsableitung 12 eindringt, wobei eine gleiche Menge Flüssigkeit aus der Flüssigkeitsableitung 12 zu entsprechenden Flüssigkeitsverbraucher bewegt wird.The valves 5, 6, 8 and 16 are initially closed, the valves 15 and 17 are open. The connection between the liquid container 9 and the pressure chamber 11 is arranged below the liquid level N1 of the liquid container 9, so that the liquid in the liquid container 9 to the liquid level N1 and in the pressure chamber 11 due to the below-described suction function of the negative pressure to the much higher Liquid level N1 'extends. By opening the valve 5, the gas under an overpressure is introduced into the pressure chamber 11, whereby the liquid is displaced to a lower liquid level N2. The valve 15 is closed and the valve 16 is opened, so that the liquid further penetrates into the liquid discharge 12, wherein an equal amount of liquid from the liquid discharge 12 is moved to corresponding liquid consumers.

Nach dem erfindungsgemäßen Verfahren zur Reinigung mit Reinigungsstrahlen wird die Reinigungsflüssigkeit vor dem Austritt mit einem unter Druck stehenden Gas beaufschlagt und dadurch zusätzlich beschleunigt wird, wodurch die Flüssigkeit nach dem Austritt einen höheren Impuls aufweist. Im beschriebenen Ausführungsbeispiel der Erfindung wird das Beaufschlagen der strömenden Reinigungsflüssigkeit gewählt.According to the inventive method for cleaning with cleaning jets, the cleaning liquid is applied before exiting with a pressurized gas and thereby additionally accelerated, whereby the liquid after exiting has a higher pulse. In the described embodiment of the invention, the application of the flowing cleaning liquid is selected.

Zur Durchführung dieses Ausführungsbeispiel des erfindungsgemäßen Verfahrens wird nun das Ventil 5 geschlossen und das weitere Ventil 6 zur Steuerung der Einleitung des Gases in die Flüssigkeitsableitung 12 geöffnet werden - oder es kann, in umgekehrter Reihenfolge, zuerst das weitere Ventil 6 zur Steuerung der Einleitung des Gases in die Flüssigkeitsableitung 12 geöffnet und dann das Ventil 5 geschlossen werden -, wodurch in beiden alternativen Verfahrensschritten das Gas in die Flüssigkeitsableitung 12 geleitet wird und das erfindungsgemäße Beaufschlagen der Reinigungsflüssigkeit mit einem unter Druck stehenden Gas erfolgt, wodurch erfindungsgemäß die Reinigungsflüssigkeit zusätzlich beschleunigt wird und die Flüssigkeit nach dem Austritt einen höheren Impuls aufweisen. Weiterhin wird ein Nachdrücken der in der Flüssigkeitsableitung 12 befindlichen Flüssigkeit bewirkt, so daß nochmals Flüssigkeit zu entsprechenden Flüssigkeitsverbrauchem bewegt wird.To carry out this embodiment of the method according to the invention, the valve 5 will now be closed and the further valve 6 will be opened to control the introduction of the gas into the liquid outlet 12 - or it may, in reverse order, first the other valve 6 to control the introduction of the gas opened in the liquid discharge 12 and then the valve 5 are closed - which in two alternative process steps, the gas is passed into the liquid discharge 12 and the inventive treatment of the cleaning liquid is carried out with a pressurized gas, whereby the cleaning liquid is additionally accelerated according to the invention and the Liquid after exiting have a higher pulse. Furthermore, a repressing of the fluid in the liquid discharge 12 is effected, so that again liquid is moved to appropriate Flüssigkeitsverbrauchem.

In der Fortsetzung des Taktpropfenverfahren wird nun das Ventil 16 sowie auch das Ventil 6 und das Ventil 8 geschlossen und das Ventil 17 geöffnet, wodurch das in dem Druckraum 11 befindliche Gas über die Entlüftungsleitung 19 und die Saugleitung 7 zum Verdichter 2 geleitet wird und ein Unterdruck in der Druckkammer 11 entsteht. Durch den Unterdruck oder, für den Fall, daß das Ventil 15 kein Rückschlagventil ist, durch Fremdsteuerung öffnet sich nun das Ventil 15, so daß Flüssigkeit durch den in der Druckkammer 11 herrschenden Unterdruck aus dem Flüssigkeitsbehälter 9 in den Druckraum 11 eingesaugt wird. Das Ventil 16 wird in Schließlage gehalten. Nun wird das Ventil 17 geschlossen und gleichzeitig wird das Ventil 8 wieder geöffnet. Dieser Vorgang wird nun solange Flüssigkeitsförderung benötigt wird wiederholt.In the continuation of the Taktpropfenverfahren now the valve 16 and the valve 6 and the valve 8 is closed and the valve 17 is opened, whereby the gas in the pressure chamber 11 is passed through the vent line 19 and the suction line 7 to the compressor 2 and a negative pressure arises in the pressure chamber 11. By the negative pressure or, in the event that the valve 15 is not a check valve, by external control now opens the valve 15, so that liquid is sucked by the pressure prevailing in the pressure chamber 11 vacuum from the liquid container 9 into the pressure chamber 11. The valve 16 is held in the closed position. Now the valve 17 is closed and at the same time the valve 8 is opened again. This process is repeated as long as fluid delivery is needed.

Nach einer bevorzugten Ausführungsform der Erfindung wird das Verfahren in Haushaltgeräten angewandt. In Fig. 2 wird eine Geschirrspülmaschine 25, im gezeigten Ausführungsbeispiel eine Haushalt-Geschirrspülmaschine beschrieben, in der das Taktpropfenverfahren und das erfindungsgemäße Verfahren zur Reinigung mit Reinigungsstrahlen mit einer Vorrichtung 1 in der in der Fig. 1 gezeigten und beschriebenen, bevorzugten Ausführungsform durchgeführt wird. Bei dieser Anwendung des erfindungsgemäßen Verfahrens in der Vorrichtung 1 ist das Gas Luft und die Flüssigkeit eine Reinigungsflüssigkeit, mit der in der Geschirrspülmaschine 25 zu reinigendes Gut beaufschlagt wird, nämlich Wasser, das ggf. mit Reinigungs- oder Klarspülmitteln vermischt und ggf. auch mit abgetragenen Speiseresten verschmutzt ist.According to a preferred embodiment of the invention, the method is applied in household appliances. FIG. 2 shows a dishwasher 25, in the exemplary embodiment shown, a domestic dishwasher in which the cycle-stopper method and the inventive method for cleaning with cleaning jets are carried out with a device 1 in the preferred embodiment shown and described in FIG. In this application of the method according to the invention in the device 1, the gas is air and the liquid is a cleaning liquid, which is acted upon in the dishwasher 25 to be cleaned Good, namely water, possibly mixed with cleaning or rinse aid and possibly also with ablated Food waste is dirty.

Der Flüssigkeitsbehälter 9 der Vorrichtung 1 wird bei der Geschirrspülmaschine 25 von dem untersten Abschnitt eines Spülbehälters 26 gebildet, der üblicherweise Pumpentopf oder Ablaufwanne genannt wird und in dem sich die von dem in Geschirrkörben 27, 28 eingefüllten, nicht gezeigten zu reinigendem Gut, z.B. Besteck, Teller, Tassen, Gläser usw., zurücklaufenden Reinigungsflüssigkeit sammelt. Das zu reinigende Gut wird mit der Reinigungsflüssigkeit durch Sprüheinrichtungen, z.B. sogenannten Sprüharmen 29, 30, beaufschlagt. Die Reinigungsflüssigkeit wird in der in Fig. 2 gezeigten und beschriebenen Anordnung mittels der Vorrichtung 1, wie zu Fig. 1 beschrieben, in die mit den Zuleitungen zu den Sprüharmen 29, 30 verbundene Flüssigkeitsableitung 12 gefördert und vor Austritt aus nicht näher beschriebenen Düsen der Sprüharme 29, 30 in der Flüssigkeitsableitung 12, nach dem erfindungsgemäßen Verfahren, mit einem unter Druck stehenden Gas beaufschlagt.The liquid container 9 of the device 1 is formed in the dishwasher 25 from the lowermost portion of a washing container 26, which is commonly called pumping pot or drain pan and in which the material to be cleaned, filled, for example, in dishes crockery 27, 28, e.g. Cutlery, plates, cups, glasses, etc., collects returning cleaning fluid. The material to be cleaned is mixed with the cleaning liquid by spraying means, e.g. so-called spray arms 29, 30, applied. The cleaning liquid is conveyed in the arrangement shown in Fig. 2 and described by means of the device 1, as described for Fig. 1, in the connected to the supply lines to the spray arms 29, 30 liquid discharge 12 and before emerging from unspecified nozzles of the spray arms 29, 30 in the liquid discharge 12, according to the method of the invention, acted upon by a pressurized gas.

Der zeitlichen Verlauf in Verbindung mit dem Taktpropfenverfahren eines mit dem zu den Fig. 1 und 2 gezeigten, bevorzugten Ausführungsbeispielen des erfindungsgemäßen Verfahrens erzeugten Sprühimpulses ist in Fig. 3 gezeigt, wobei die Fig. 3 den zeitlichen Ablauf und den erzeugten Wasserdruck ab dem Zeitpunkt des Öffnen des Ventils 17 zum Ansaugen der Reinigungsflüssigkeit in den Druckraum 11 zeigt. Der Zeitraum zum Ansaugen ist in Fig. 3 mit Ts bezeichnet und beträgt etwa eine Sekunde. Nun wird über eine Zeitdauer Tp von etwa einer halben Sekunde eine Pause eingelegt.The timing in connection with the Taktpropfenverfahren a spray pulse generated with the shown in FIGS. 1 and 2, preferred embodiments of the inventive method is shown in Fig. 3, wherein the timing and the water pressure generated from the time of Opening the valve 17 for sucking the cleaning liquid into the pressure chamber 11 shows. The period for aspiration is designated Ts in FIG. 3 and is approximately one second. Now a break is taken over a period Tp of about half a second.

Danach folgt die Beaufschlagung der Reinigungsflüssigkeit mit dem unter Druck stehenden Gas vor dem Austritt der Reinigungsflüssigkeit nach dem erfindungsgemäßen Verfahren, wobei im gezeigten Ausführungsbeispiel der Erfindung eine impulsartige Förderung der Reinigungsflüssigkeit durch Öffnen des Ventils 5 mit einer Impulshöhe lf von im Ausführungsbeispiel ca. 310 Millibar und das Nachdrücken durch Öffnen des Ventils 6 mit einer lmpulshöhe In von im Ausführungsbeispiel zusätzlich ca. 90 Millibar zusammen über eine Zeitdauer Ti von im Ausführungsbeispiel einer halben Sekunde durchgeführt wird. Mit dieser sehr kurzen Impulsdauer Ti wird die Reinigungswirkung der unter Druck auf das zu reinigende Gut aufgebrachten Reinigungsflüssigkeit optimiert.This is followed by the loading of the cleaning liquid with the pressurized gas before the exit of the cleaning liquid by the method according to the invention, wherein in the illustrated embodiment of the invention, a pulse-like promotion of the cleaning liquid by opening the valve 5 with a pulse height lf of about 310 millibar and in the embodiment the additional pressures by opening the valve 6 with a pulse height In of in the exemplary embodiment additionally about 90 millibars together over a period of Ti in the embodiment of half a second is performed. With this very short pulse duration Ti, the cleaning effect of the cleaning liquid applied under pressure to the material to be cleaned is optimized.

Alternativ könnte nach dem erfindungsgemäßen Verfahren das Gas auch in eine stehende Reinigungsflüssigkeit eingeblasen werden. Weiterhin ist das erfindungsgemäße Verfahren auch mit einem intermittierend eingeblasenen Gas durchführbar. Auch eine Beigabe von Zusatzmittel zu dem Gas ist nach dem erfindungsgemäßen Verfahren möglich.Alternatively, the gas could also be blown into a standing cleaning liquid by the process according to the invention. Furthermore, the method according to the invention also with an intermittently injected gas feasible. An addition of additive to the gas is possible by the method according to the invention.

Bei einer Beaufschlagung des zu reinigenden Gutes im zeitlichen Abstand, wie z.B. bei dem oben geschilderten Taktpropfenförderverfahren, erfolgt bei jedem Beginn der Beaufschlagung ein Druckanstieg in der beaufschlagenden Reinigungsflüssigkeit sowie bei jedem Ende der Beaufschlagung ein Abfall des Druckes in der beaufschlagenden Reinigungsflüssigkeit. In der Praxis hat sich gezeigt, daß durch das abwechselnde Ansteigen und Abfallen des Druckes der Reinigungsflüssigkeit und der damit verursachten abwechselnde Ansteigen und Abfallen der auf die Verschmutzungen auf dem zu reinigenden Gut wirkenden mechanischen Kräfte, ein gutes Reinigungsergebnis bei einer kurzen Dauer der Beaufschlagung erreicht wird.When loading the material to be cleaned at a time interval, such. In the above-described Taktpropfenförderverfahren, at each start of the application, a pressure increase in the applied cleaning liquid and at each end of the application, a drop in the pressure in the applied cleaning liquid. In practice, it has been found that by the alternating increase and decrease of the pressure of the cleaning liquid and the thus caused alternating increase and decrease of acting on the contaminants on the material to be cleaned mechanical forces, a good cleaning result is achieved with a short duration of exposure ,

Dieses Reinigungsergebnis wird, wie ebenfalls in der Praxis nachgewiesen, noch wesentlich verbessert, wenn, nach dem erfindungsgemäßen Verfahren, die Förderung der Reinigungsflüssigkeit durch Beaufschlagung mit einem unter Druck stehenden Gas vor dem Austritt und damit impulsartig erfolgt, wobei das abwechselnde Ansteigen und Abfallen des Druckes der Reinigungsflüssigkeit und der damit verursachten abwechselnde Ansteigen und Abfallen der auf die Verschmutzungen auf dem zu reinigenden Gut wirkenden mechanischen Kräfte in sehr kurzer Zeitdauer und damit sehr intensiv stattfindet.This cleaning result is, as also shown in practice, significantly improved when, according to the inventive method, the promotion of the cleaning liquid by applying a pressurized gas before exiting and thus pulse-like manner, wherein the alternating increase and decrease of the pressure the cleaning liquid and the thus caused alternating increase and decrease of acting on the contaminants on the material to be cleaned mechanical forces in a very short period of time and thus takes place very intense.

Mit dem erfindungsgemäßen Verfahren der Erhöhung des Impulses der Tropfen eines Reinigungsstrahles wird zwangsläufig die Intensität des mechanischen Abtrages auf der Oberfläche des zu reinigenden Gutes erhöht, d.h. die Wirksamkeit des Reinigungsstrahles verbessert, wodurch, da ein ausreichendes Reinigungsergebnis hauptsächlich durch eine ausreichende Dauer der Beaufschlagung des zu reinigenden Gutes und den dabei über die Zeitdauer erfolgenden mechanischen Abtrag von Verschmutzungen auf dem zu reinigenden Gutes erzielt wird, die Dauer des Reinigungsprogrammes verkürzt und damit weniger Energie zur Förderung der Reinigungsflüssigkeit benötigt wird. Bei Reinigungsverfahren, bei denen die Reinigungsflüssigkeit nicht wiederverwendet wird, wird mit dem erfindungsgemäßen Verfahren weiterhin noch eine beträchtliche Menge an Reinigungsflüssigkeit eingespart. Mit der Erfindung ist ein Verfahren zur Reinigung mit Reinigungsstrahlen der eingangs genannten Art geschaffen, bei dem Energie eingespart und die Dauer des Reinigungsprogrammes verkürzt werden kann.With the method according to the invention of increasing the momentum of the drops of a cleaning jet, the intensity of the mechanical removal on the surface of the material to be cleaned is inevitably increased, i. improves the effectiveness of the cleaning jet, whereby, as a sufficient cleaning result is achieved mainly by a sufficient duration of the loading of the material to be cleaned and thereby taking place over the period mechanical removal of dirt on the goods to be cleaned, shortening the duration of the cleaning program and thus less Energy is required to promote the cleaning fluid. In cleaning processes in which the cleaning liquid is not reused, the inventive method still saves a considerable amount of cleaning liquid. With the invention, a method for cleaning with cleaning jets of the type mentioned is created, can be saved in the energy and the duration of the cleaning program can be shortened.
