Abstract
Die Erfindung betrifft eine Vorrichtung zur Beaufschlagung von flächigem Material mittels eines unter Druck stehenden Mediums, bestehend aus einem Düsenbalken, einer dem Düsenbalken vorgeordneten Hochdruckpumpe sowie einer zwischen Düsenbalken und Hochdruckpumpe geschalteten Filtration. Erfindungsgemäß sind zwei parallele Leitungszweige (3.1, 3.2), in welchen je ein Filter (4.1, 4.2) mit zugeordneten Sperrventilen (6.1, 6.2, 7.1, 7.2) angeordnet ist, vorgesehen.The invention relates to a device for acting on sheet material by means of a pressurized medium, consisting of a nozzle bar, a nozzle bar upstream upstream high-pressure pump and a switched between the nozzle bar and high-pressure pump filtration. According to the invention, two parallel line branches (3.1, 3.2), in each of which a filter (4.1, 4.2) with associated shut-off valves (6.1, 6.2, 7.1, 7.2) is arranged, are provided.
Description
Die Erfindung betrifft eine Vorrichtung zur Beaufschlagung von flächigem Material mittels eines unter Druck stehenden Mediums gemäß dem Oberbegriff von Anspruch 1.The The invention relates to a device for the application of planar Material by means of a pressurized medium according to the Preamble of claim 1.
Aus
der
Der Düsenbalken wird über eine Pumpe mit unter hohem Druck stehendem Wasser versorgt. Zwischen Pumpe und Düsenbalken ist als Filtration ein Filter (Polizeifilter) geschaltet, um im Druckwasser befindliche Partikel herauszufiltern. Eine Verschmutzung des Düsenstreifens wird so vermieden. Ein Auswechseln dieses Filters nach einer bestimmten Betriebszeit bedingt aber ein Stillsetzen der Anlage, da dies nur im Druckfreien Zustand des Leitungssystems möglich ist.Of the Nozzle bar is being pumped high Supplied with pressurized water. Between pump and nozzle bar is as filtration a filter (police filter) switched to in the Filter out particles containing pressurized water. A pollution the nozzle strip is avoided. An exchange of this Filters after a certain period of operation but requires a shutdown the plant, as this is only in the pressure-free state of the pipe system is possible.
Aufgabe der vorliegenden Erfindung ist es, eine Vorrichtung der gattungsgemäßen Art zu verbessern und insbesondere einen Filterwechsel während des Betriebes zu ermöglichen.task It is the object of the present invention to provide a device of the generic type Kind of improve and in particular a filter change during to enable the operation.
Gelöst wird diese Aufgabe durch die kennzeichnenden Merkmale des Hauptanspruches. Vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.Solved This object is achieved by the characterizing features of the main claim. Advantageous developments of the invention will become apparent from the Dependent claims.
Gemäß der Erfindung ist vorgesehen, dass zwischen Hochdruckpumpe und Düsenbalken über ein entsprechend gestaltetes Leitungssystem zwei Filter parallel geschaltet sind. Über im Leitungssystem angeordnete Ventileinrichtungen sind die Filter schaltbar. So kann durch Schalten der Ventile in dem einen Leitungszweig das auszuwechselnde Filter druckfrei gesetzt und dieses sodann ausgetauscht werden. Nach dem Filtertausch in dem einen Leitungszweig werden die entsprechenden Ventile zum Entlüften des Filters geschaltet. Nach vollständigem Druckaufbau in diesem Leitungszweig wird durch Schalten der Ventile in dem anderen Leitungszweig das dort angeordnete Ventil stillgesetzt.According to the Invention is envisaged that between the high-pressure pump and nozzle bar via a appropriately designed line system connected in parallel two filters are. About arranged in the line system valve devices the filters are switchable. So can by switching the valves in the one line branch to set the filter to be replaced pressure-free and then replaced. After the filter change in The one branch of the pipeline will be the corresponding valves for venting the filter switched. After complete pressure build-up in this leg is by switching the valves in the other Line branch stopped there arranged valve.
Da die Drücke in dem Leitungssystem 100 und mehr bar betragen sind gemäß der Erfindung besonders vorteilhafte Ventilausführungen sowie eine Schaltung der Ventile vorgesehen. So sind in jedem der beiden Leitungszweige den Filtern ein Kugelventil vor- und ein Kugelventil nachgeordnet. Durch diese Ventile kann das jeweilige Ventil vollständig abgesperrt werden. Den in Strömungsrichtung den Filtern vorgeordneten Kugelventilen ist je ein Drosselventil in Reihe vorgeschaltet, mittels dem die Durchflussmenge kontinuierlich von einem während des Betriebes herrschenden Wert auf Null herunter steuerbar ist. Dadurch sind negative Auswirkungen, welche sich bei einer plötzlichen Druckänderung ergeben, vermeidbar. Ist in dem Leitungszweig, in welchem das Filter zu wechseln ist, das zugehörige Drosselventil vollständig geschlossen, so können die beiden Kugelventile geschlossen werden. Über ein zugeordnetes Entlüftungsventil kann das so vom Durchfluss abgetrennte Filter druckfrei geschaltet und sodann ausgetauscht werden. Die Druckwasserversorgung des Düsenbalkens während des Filtertausches erfolgt über das Filter in dem anderen Leitungszweig. Entsprechend sind die Kugelventile sowie das Drosselventil in diesem Zweig geschaltet.There the pressures in the conduit system 100 and more bar amount are particularly advantageous according to the invention Valve versions and a circuit of the valves provided. Thus, in each of the two branches of the filters, a ball valve upstream and downstream of a ball valve. Through these valves can the respective valve are completely shut off. The in the flow direction upstream of the filters ball valves is ever upstream of a throttle valve in series, by means of which the Flow rate continuously from one during operation ruling value down to zero is controllable. Thereby are negative effects, which occur in a sudden Pressure change result, avoidable. Is in the line branch, in which the filter is to be changed, the associated throttle valve completely closed, so can the two ball valves getting closed. Via an assigned venting valve The filter thus separated from the flow can be switched pressure-free and then replaced. The pressurized water supply of the nozzle bar during the filter exchange takes place via the filter in the other leg. Accordingly, the ball valves as well as the throttle valve in this branch switched.
Nachdem in dem zuvor druckfrei geschalteten Leitungszweig das Filter gewechselt wurde, wird das auf der Zufuhrseite des Filters befindliche Kugelventil geöffnet und das Drosselventil leicht geöffnet. Über das nun ebenfalls geöffnete Entlüftungsventil kann die im neuen Filter befindliche Luft aus dem System ausgeblasen werden. Nach Schließen des Entlüftungsventils wird das auslassseitige Kugelventil geöffnet, woraufhin das Drosselventil nun ebenfalls vollständig geöffnet wird. Der Leitungszweig ist nun vollständig für die Druckwasserversorgung freigegeben. In entsprechender Weise kann nun der zweite Leitungszweig abgeschaltet werden.After this in the previously switched pressure-free line branch the filter is, the ball valve located on the supply side of the filter opened and the throttle valve opened slightly. about the now also open vent valve can the air in the new filter is blown out of the system become. After closing the bleeder valve the outlet-side ball valve is opened, whereupon The throttle valve now also fully open becomes. The line branch is now completely for the pressurized water supply released. In a similar way can now the second line branch are turned off.
Des Weiteren erfolgt die Erläuterung eines Ausführungsbeispieles anhand der Zeichnungen.Of Further, the explanation of an embodiment is given based on the drawings.
