Die Anlage 10 in Fig. 1 für das Behandeln von Werkstücken 14 mit einem Prozessfluid 18 ist als eine Anlage für das Reinigen der Werkstücke 14 ausgelegt. Das Prozessfluid 18 in der Anlage 10 ist eine Flüssigkeit, z. B. Wasser. In der Anlage 10 gibt es eine Prozesskammer 12 für das Aufnehmen eines zu behandelnden Werkstücks 14. Die Prozesskammer 12 ist in einem kesselförmigen Behälter 20 ausgebildet, der eine zylindrische Seitenwand 22 und einen trichterförmige Boden 24 mit einem Auslass 26 hat. Der kesselförmige Behälter 20 ist mit einem Deckel 28 verschließbar. In der Prozesskammer 12 gibt es einen Werkstückaufnahmebereich 30.The plant 10 in Fig. 1 for treating workpieces 14 with a process fluid 18 is designed as a facility for cleaning the workpieces 14. The process fluid 18 in the system 10 is a liquid, e.g. B. water. In the plant 10 there is a process chamber 12 for receiving a workpiece 14 to be treated. The process chamber 12 is formed in a vessel-shaped container 20 having a cylindrical side wall 22 and a funnel-shaped bottom 24 with an outlet 26. The vessel-shaped container 20 can be closed with a cover 28. In the process chamber 12 there is a workpiece receiving area 30.

Das Leitungssystem in der Anlage 10 weist einen Verbindungskanal 42 auf, der einen Fluidbehälter 44 mit Leitungskanälen 46 verbindet, die an die Adapter 34 angeschlossen sind. Die Anlage 10 enthält eine Saugeinrichtung 48, die durch einen Saugkanal 50 mit einem Auslass 52 der Prozesskammer 12 verbunden ist. Die Saugeinrichtung 48 dient für das Erzeugen eines Unterdrucks in der Prozesskammer 12. Die Saugeinrichtung 48 hat einen Vakuumbehälter 54 und weist eine mit dem Vakuumbehälter 54 durch eine Saugleitung 56 verbundene Evakuierungsvorrichtung 58 mit einer Vakuumpumpe auf. In der Saugleitung 56 ist ein Absperrventil 60 angeordnet, mittels dessen die Saugleitung 56 wahlweise gesperrt und freigegeben werden kann, um die Evakuierungsvorrichtung 58 mit dem Vakuumbehälter 54 zu verbinden oder um die Evakuierungsvorrichtung 58 von dem Vakuumbehälter 54 abzutrennen. Der Vakuumbehälter 54 hat einen mit einem Absperrventil 62 verschließbaren Auslass 64 für das Abführen von Prozessfluid 18.The line system in the system 10 has a connection channel 42, which connects a fluid container 44 with ducts 46, which are connected to the adapter 34. The system 10 includes a suction device 48, which is connected by a suction channel 50 to an outlet 52 of the process chamber 12. The suction device 48 serves to generate a negative pressure in the process chamber 12. The suction device 48 has a vacuum container 54 and has an evacuation device 58 connected to the vacuum container 54 through a suction line 56 with a vacuum pump. In the suction line 56, a shut-off valve 60 is arranged, by means of which the suction line 56 can be selectively locked and released to connect the evacuation device 58 to the vacuum tank 54 or to separate the evacuating device 58 from the vacuum container 54. The vacuum vessel 54 has an outlet 64 closable with a shut-off valve 62 for the removal of process fluid 18.

In der Anlage 10 mündet der Verbindungskanal 42 in den Saugkanal 50. In dem Verbindungskanal 42 ist ein erstes einstellbares Ventil 66 und ein weiteres einstellbares Ventil 68 angeordnet, die mit einer Rechnereinheit (nicht gezeigt) gesteuert werden können. Mittels des ersten einstellbaren Ventils 66 kann der Strömungsweg für Prozessfluid 18 aus dem Fluidbehälter 44 zu den Leitungskanälen 46 mit dem an den Werkstückkörper 32 angepassten Adapter 34 wahlweise freigegeben und gesperrt werden. Das zweite einstellbare Ventil 68 dient für das wahlweise Freigeben und Sperren des Strömungswegs für Prozessfluid 18 aus den Leitungskanälen 46 zu dem Vakuumbehälter 54 der Saugeinrichtung 48. Für das Freigeben und Sperren des Saugkanals 50 gibt es in der Anlage 10 ein Absperrventil 65. Der kesselförmige Behälter 20 kann über ein Belüftungsventil 94 belüftet werden.In the system 10, the connecting channel 42 opens into the suction channel 50. In the connecting channel 42, a first adjustable valve 66 and another adjustable valve 68 is arranged, which can be controlled with a computer unit (not shown). By means of the first adjustable valve 66, the flow path for process fluid 18 can be selectively released and blocked from the fluid container 44 to the conduit channels 46 with the adapted to the workpiece body 32 adapter 34. The second adjustable valve 68 is for selectively enabling and disabling the flow of process fluid 18 from the conduit 46 to the vacuum vessel 54 of the aspirator 48. For disengaging and disabling the aspiration conduit 50, there is a check valve 65 in the system 10. The vessel-shaped vessel 20 can be vented via a vent valve 94.

Um ein in der Prozesskammer 12 der Anlage 10 ein Werkstück 14 mit der Prozessfluid 18 zu behandeln und es dabei zu reinigen, wird in einem ersten Schritt das Werkstück 14 in dem Werkstückaufnahmebereich 30 auf der Seite der ersten Öffnungen 36 in der Prozesskammer 12 an die Adapter 34 angelegt. In einem zweiten Schritt werden das einstellbare Ventil 68 in dem Verbindungskanal 42 und das Absperrventil 65 in der Saugkanal 50 geschlossen. Durch Öffnen des Absperrventils 60 wird dann in einem dritten Schritt mittels der Evakuierungsvorrichtung 58 in dem Vakuumbehälter 54 ein Unterdruck von etwa 950 mbar erzeugt, wobei das Absperrventil 62 geschlossen ist.In order to treat a workpiece 14 with the process fluid 18 in the process chamber 12 of the system 10 and to clean it, in a first step, the workpiece 14 in the workpiece receiving area 30 on the side of the first openings 36 in the process chamber 12 to the adapter 34 created. In a second step, the adjustable valve 68 in the connection channel 42 and the shut-off valve 65 in the suction channel 50 are closed. By opening the shut-off valve 60, a vacuum of about 950 mbar is then generated in the vacuum vessel 54 in a third step by means of the evacuation device 58, the shut-off valve 62 being closed.

In einem vierten Schritt wird das Absperrventil 65 und das Ventil 66 dann geöffnet. Diese Maßnahme bewirkt, dass die Prozesskammer 12 schlagartig mit dem Unterdruck in dem Vakuumbehälter 54 der Saugeinrichtung 48 beaufschlagt wird. Aufgrund dieses Unterdrucks wird aus dem Fluidbehälter 44 durch die Leitungskanäle 46 und die Adapter 34 dann über die Öffnungen 36 des Werkstückkörpers 32 Prozessfluid 18 in den darin ausgebildeten Hohlraum 38 eingesaugt. Das in den Hohlraum 38 eingesaugte Prozessfluid 18 gelangt dann durch die nicht mittels der Adapter 34 abgedeckten Öffnungen 70 in das Innere der Prozesskammer 12.In a fourth step, the shut-off valve 65 and the valve 66 are then opened. This measure has the effect that the process chamber 12 is abruptly subjected to the negative pressure in the vacuum container 54 of the suction device 48. Due to this negative pressure is from the fluid container 44th through the ducts 46 and the adapter 34 then sucked through the openings 36 of the workpiece body 32 process fluid 18 in the cavity 38 formed therein. The process fluid 18 sucked into the cavity 38 then passes through the not covered by the adapter 34 openings 70 in the interior of the process chamber 12th

Die Fig. 2 zeigt die Anlage 10 in einem von dem in der Fig. 1 gezeigten Betriebszustand verschiedenen Betriebszustand mit in die Prozesskammer 12 durch die Öffnungen 36 und den Hohlraum 38 des Werkstücks 14 eingesaugtem Prozessfluid 18 aus dem Fluidbehälter 44. Für das Einstellen dieses Betriebszustands wird in einem vierten Schritt das Ventil 68 der Anlage 10 geschlossen. Das Prozessfluid 18 strömt dann in der mit den Pfeilen 74 kenntlich gemachten Strömungsrichtung durch den Hohlraum 38 in die Prozesskammer 12 ein. An den Wänden des Hohlraums 38 angelagerte Schmutzpartikel und Schmutzstoffe 39 werden hier von dem Prozessfluid 18 abgetragen und in die Prozesskammer 12 gespült.The Fig. 2 shows the plant 10 in one of the in the Fig. 1 shown operating state with sucked into the process chamber 12 through the openings 36 and the cavity 38 of the workpiece 14 process fluid 18 from the fluid container 44. For setting this operating state, the valve 68 of the system 10 is closed in a fourth step. The process fluid 18 then flows in the direction indicated by the arrows 74 flow direction through the cavity 38 into the process chamber 12 a. On the walls of the cavity 38 accumulated dirt particles and contaminants 39 are removed here by the process fluid 18 and rinsed into the process chamber 12.

Die Fig. 3 zeigt die Anlage 10 in einem von den in der Fig. 1 und der Fig. 2 gezeigten Betriebszuständen verschiedenen weiteren Betriebszustand. Für das Einstellen dieses Betriebszustands wird das Absperrventil 65 in dem Saugkanal 50 hier in einem fünften Schritt wieder gesperrt, das Ventil 66 in dem Verbindungskanal 42 geschlossen und das Ventil 68 in dem Verbindungsanal 42 geöffnet. Aus der mit Prozessfluid 18 angefüllten Prozesskammer 12 wird das Prozessfluid 18 dann in der mittels der Pfeile 76 kenntlich gemachten Strömungsrichtung mittels der Saugeinrichtung 48 durch den Hohlraum 38 in dem Werkstückkörper 32 des Werkstücks 14 gesaugt und in den Vakuumbehälter 54 der Saugeinrichtung 48 eingetragen.The Fig. 3 shows the plant 10 in one of the in the Fig. 1 and the Fig. 2 shown operating states various other operating condition. In order to set this operating state, the shut-off valve 65 in the suction channel 50 is hereby blocked again in a fifth step, the valve 66 in the connecting channel 42 is closed and the valve 68 in the connecting channel 42 is opened. From the process chamber 12 filled with process fluid 18, the process fluid 18 is then sucked in the direction indicated by the arrows 76 flow direction by means of the suction device 48 through the cavity 38 in the workpiece body 32 of the workpiece 14 and registered in the vacuum container 54 of the suction device 48.

Die Strömungsrichtung des Prozessfluids 18 ist dabei der mit den Pfeilen 76 kenntlich gemachten Strömungsrichtung in dem in der Fig. 2 gezeigten Betriebszustand der Anlage 10 entgegengesetzt. An den Wänden des Hohlraums 38 angelagerte Schmutzpartikel und Schmutzstoffe werden dabei erneut von dem Prozessfluid 18 abgetragen und gelangen so in den Vakuumbehälter 54.The flow direction of the process fluid 18 is the direction indicated by the arrows 76 flow direction in the in the Fig. 2 shown operating state of the system 10 opposite. In this case, dirt particles and contaminants deposited on the walls of the cavity 38 are again removed from the process fluid 18 and thus reach the vacuum container 54.

In einem sechsten Schritt wird das in dem Vakuumbehälter 54 angesammelte Prozessfluid 18 dann aus dem Vakuumbehälter 54 der Saugeinrichtung 48 abgeführt, indem das Absperrventil 62 in dem Auslass 64 geöffnet wird. Dabei ist das Absperrventil 60 geschlossen.In a sixth step, the process fluid 18 collected in the vacuum vessel 54 is then removed from the vacuum vessel 54 of the suction device 48 by opening the shut-off valve 62 in the outlet 64. The shut-off valve 60 is closed.

Für das Behandeln bzw. Reinigen eines Werkstücks mit dem Prozessfluid 18 können die vorgenannten Schritte gegebenenfalls mehrfach aufeinanderfolgend wiederholt werden.For the treatment or cleaning of a workpiece with the process fluid 18, the abovementioned steps can optionally be repeated several times in succession.

Bei geöffnetem Deckel 28 der Prozesskammer wird dann das Werkstück 14 der Prozesskammer 12 entnommen um dann in der Prozesskammer 12 ein weiteres, entsprechendes Werkstück zu behandeln.When the cover 28 of the process chamber is open, the workpiece 14 is then removed from the process chamber 12 in order then to treat a further, corresponding workpiece in the process chamber 12.

Die Anlage 110 enthält einen Leitungskanal 78 mit einem Absperrventil 80, durch den Prozessfluid 18 aus der Prozesskammer 12 in den Vakuumbehälter 54 bewegt werden kann. Für das Herstellen eines Unterdrucks in der Prozesskammer 12 wird das Absperrventil 65 geöffnet, wenn der Vakuumbehälter 54 der Evakuierungsvorrichtung 58 evakuiert ist. Die einstellbaren Ventile 66, 68 sind dabei geschlossen. Auch das Absperrventil 80 in dem Leitungskanal 78 ist gesperrt.In the system 110, the suction channel 50 opens for the application of negative pressure in the process chamber 12 in the portion of the lid 28. The system 110 includes a conduit 78 with a check valve 80, are moved by the process fluid 18 from the process chamber 12 into the vacuum vessel 54 can. For establishing a negative pressure in the process chamber 12, the check valve 65 is opened when the vacuum tank 54 of the evacuation device 58 is evacuated. The adjustable valves 66, 68 are closed. The shut-off valve 80 in the conduit 78 is locked.

Durch Öffnen des Ventils 66 wird das Einströmen von Prozessfluid 18 in die Prozesskammer 12 durch den Hohlraum 38 des Werkstücks 14 aus dem Fluidbehälter 44 bewirkt. Wenn die Prozesskammer 12 mit Prozessfluid 18 angefüllt ist, werden das Absperrventil 65 und das Ventil 66 gesperrt. Dann wird das Ventil 68 geöffnet, so dass mit einer der Strömungsrichtung beim Einströmen in die Prozesskammer 12 entgegengesetzten Strömungsrichtung Prozessfluid 18 durch den Verbindungskanal 42 und den Saugkanal 50 in den Vakuumbehälter 54 der Saugeinrichtung 48 gelangt.By opening the valve 66, the inflow of process fluid 18 into the process chamber 12 through the cavity 38 of the workpiece 14 from the fluid container 44 is effected. When the process chamber 12 is filled with process fluid 18 is, the check valve 65 and the valve 66 are locked. Then, the valve 68 is opened so that process fluid 18 passes through the connecting channel 42 and the suction channel 50 into the vacuum container 54 of the suction device 48 with one of the flow direction when flowing into the process chamber 12 opposite flow direction.

Zu bemerken ist, dass für das Absaugen von Prozessfluid 18 aus der Prozesskammer 12 das Ventile 68 und das Absperrventil 80 zueinander zeitversetzt geöffnet und geschlossen werden können. Z. B. kann das Ventil 68 vor dem Absperrventil 80 geöffnet werden, um damit zu erreichen, dass das Prozessfluid 18 zunächst durch den Hohlraum 38 in dem Werkstückkörper 32 des Werkstücks 14 gesaugt wird. Dann wird das Ventil 68 geschlossen, um das mit Schmutzpartikeln befrachtete Prozessfluid dann über den Auslass 26 des Behälters 20 mittels der Saugeinrichtung 48 abzusaugen.It should be noted that for the extraction of process fluid 18 from the process chamber 12, the valves 68 and the shut-off valve 80 can be opened and closed with a time delay to each other. For example, the valve 68 may be opened in front of the shut-off valve 80 to cause the process fluid 18 to be initially drawn through the cavity 38 in the workpiece body 32 of the workpiece 14. Then, the valve 68 is closed to then suck the contaminant-laden process fluid via the outlet 26 of the container 20 by means of the suction device 48.
