Description

Vorrichtung zur Beaufschlagung von flächigem Material mittels eines unter Druck stehenden Mediums Device for acting on sheet material by means of a pressurized medium
Die Erfindung betrifft eine Vorrichtung zur Beaufschlagung von flächigem Material mittels eines unter Druck stehenden Mediums gemäß dem Oberbegriff von Anspruch 1.The invention relates to a device for acting on sheet material by means of a pressurized medium according to the preamble of claim 1.
Aus der DE 603 07 058 T2 ist eine Vorrichtung zur Beaufschlagung von flächigem Material mittels einem unter Druck stehenden Fluid bekannt. Die Vorrichtung besteht jeweils aus einem Düsenbalken (Wasserbalken), der an seiner Unterseite einen Düsenstreifen mit einer Vielzahl feiner Austrittsöffnungen für ein unter Druck stehendes Medium, insbesondere Wasser aufweist. Der vorzugsweise in Form einer Bahn unter dem Düsenbalken transportierte gewebte, gewirkte Stoff bzw. Vliesstoff (Nonwoven) wird mit den Druckwasserstrahlen beaufschlagt. Bei einem Vlies kann so eine Verfestigung bzw. eine Verschlingung der Fasern, der Filamente erzeugt werden.From DE 603 07 058 T2 discloses a device for acting on sheet material by means of a pressurized fluid is known. The device consists of a nozzle bar (water bar), which has on its underside a nozzle strip with a plurality of fine outlet openings for a pressurized medium, in particular water. The woven, knitted fabric or nonwoven fabric (nonwoven), which is preferably transported in the form of a web under the nozzle bar, is acted upon by the pressurized water jets. In the case of a nonwoven, such a solidification or entanglement of the fibers or filaments can be produced.
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 herauszufiltem. 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. Aufgabe der vorliegenden Erfindung ist es, eine Vorrichtung der gattungsgemäßen Art zu verbessern und insbesondere einen Filterwechsel während des Betriebes zu ermöglichen.The nozzle bar is supplied by a pump with high pressure water. Between the pump and the nozzle bar, a filter (police filter) is used as filtration to filter out any particles in the pressurized water. Soiling of the nozzle strip is avoided. Replacement of this filter after a certain period of operation, however, requires a shutdown of the system, since this is possible only in the pressure-free state of the pipe system. Object of the present invention is to improve a device of the generic type and in particular to allow a filter change during operation.
Gelöst wird diese Aufgabe durch die kennzeichnenden Merkmale des Hauptanspruches. Vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.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 eine Vorrichtung zur Beaufschlagung von flächigem Material mittels eines unter Druck stehenden Mediums vorgesehen, bestehend aus einem Düsenbalken, einer dem Düsenbalken vorgeordneten Hochdruckpumpe sowie einer zwischen Düsenbalken und Hochdruckpumpe geschalteten Filtration, mit zwei parallelen Leitungszweigen, in welchen je ein Filter mit zugeordneten Sperrventilen angeordnet ist.According to the invention, a device for acting on sheet material by means of a pressurized medium is provided, consisting of a nozzle bar, a nozzle bar upstream high-pressure pump and a connected between the nozzle bar and high-pressure pump filtration, with two parallel lines, in each of which a filter with associated Check valves is arranged.
Weiterbildend ist vorgesehen:Further education is provided:
- jedem Filter ist ein Drosselventil vorgeordnet.- Each filter is preceded by a throttle valve.
- in Strömungsrichtung sind in jedem Leitungszweig einem Filter ein Sperrventil vor- und ein Sperrventil nachgeordnet.- In the direction of flow in each line branch a filter upstream of a check valve and downstream of a check valve.
- in jedem Leitungszweig ist eine Entlüftung mit einem Sperrventil angeordnet.- In each line branch a vent with a check valve is arranged.
- die Sperrventile sind als Kugelventile ausgebildet.- The check valves are designed as ball valves.
Der erfindungsgemäße Vorteil besteht darin, dass zwischen Hoch- druckpumpe 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 Lei- tungszweig das dort angeordnete Ventil stillgesetzt.The advantage of the invention is that between pressure pump and nozzle bars are connected in parallel via a correspondingly designed line system two filters. About arranged in the line system valve devices, the filter can be switched. Thus, by switching the valves in the one branch, the filter to be replaced pressure-free set and this will then be replaced. After the filter change in the one branch of the line, the corresponding valves are switched to vent the filter. After complete pressure build-up in this line branch, the valve arranged there is shut down by switching the valves in the other line branch.
Da die Drücke in dem Leitungssystem 100 bar und mehr 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 Ku- gelventile 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 Kugel- ventile sowie das Drosselventil in diesem Zweig geschaltet. 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 neu- en 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.Since the pressures in the line system are 100 bar and more particularly advantageous valve designs and a circuit of the valves are provided according to the invention. Thus, in each of the two line branches the filters a ball valve upstream and downstream of a ball valve. Through these valves, the respective valve can be completely shut off. The ball valves upstream of the filters in the flow direction are each preceded in series by a throttle valve, by means of which the flow rate can be controlled continuously from zero to zero during operation. As a result, negative effects that arise in a sudden pressure change, avoidable. If the associated throttle valve is completely closed in the line branch in which the filter is to be changed, the two ball valves can be closed. Via an assigned vent valve, the filter thus separated from the flow can be pressure-free switched and then replaced. The pressurized water supply of the nozzle bar during the filter exchange takes place via the filter in the other line branch. Accordingly, the ball valves and the throttle valve are connected in this branch. After the filter has been changed in the previously pressure-free connected line branch, the ball valve located on the supply side of the filter is opened and the throttle valve is slightly opened. The air in the new filter can be blown out of the system via the now open vent valve. After closing the vent valve, the outlet-side ball valve is opened, whereupon the throttle valve is now also fully opened. The line branch is now fully released for the pressurized water supply. In a corresponding manner, the second line branch can now be switched off.
