- the present invention relates to a dampening solution filter system for the dampening solution circuit of an offset printing machine according to the preamble of claim 1.
- Filter systems of the type mentioned are used to clean the dampening solution, which is kept in a circuit for operating the dampening unit of an offset printing press, and to make available for reuse.
- the usual filter systems include a fountain solution tank, which is integrated into a separate from the printing machine conditioning device. Through a return line, the excess dampening solution from the printing machine is returned to the tank, while a flow line is used to direct the filtered dampening solution from the tank to the printing press.
- a fine filtration module which is usually integrated in the return line and includes a potential absorption filter.
- the cleaning principle of this filter is based on the fact that the particles to be filtered out contained in the dampening solution generally have a negative electrical zeta potential and can therefore be easily bound by an absorption filter, which is occupied by an opposite, namely positive electrical potential.
- the previously used fine filtration modules are separate units which are provided to the dampening solution tank or a treatment device containing the tank. This leads to an increased space requirement and to a greater expenditure on equipment. As the dampening solution filter systems are often used in areas with limited space, additional system components are a particular problem. In addition, the additional device module causes increased costs of the system. Moreover, in the conventional constructions, the throughput of the dampening solution circuit between the tank and the printing machine is limited by the comparatively small throughput of the fine filtration module.
- Object of the present invention is therefore to provide a dampening solution filter system of the type mentioned, which is more compact than the previous systems and thus reduces the space required and cheaper to install, and which also has a throughput in dampening solution circuit between the tank and printing press which is independent of the throughput of the fine filtration module.
- the fine filtration module of the dampening solution filter system is not a separate device unit, but is integrated into the tank. Thanks to this design, the tank volume is used to attach the fine filtration module. A separate auxiliary device is not required, and the overall construction is considerably more compact. In addition, the fine filtration module is not located in the return line, but separated from this. Corresponding facilities of the dampening solution filter system serve for passing the fountain solution cached in the tank through the fine filtration module. The throughput of the moisturizer cycle between the tank and the press is thus independent of the throughput of the module.
- the means for passing the dampening solution through the fine filtration module comprise a recirculation line which is connected at one end to the module and whose opposite end opens into the tank.
- the fine filtration module is preferably located either at the outlet end or at the inlet end of the recirculation line.
- said means further comprises a circulation pump disposed in the recirculation line.
- the fine filtration module comprises an activated carbon filter downstream of the potential absorption filter.
- the fine filtration module and an optionally present activated carbon filter are inserted into a filter housing.
- This filter housing is preferably approximately cylindrical, and the recirculation line opens into an end face of the filter housing.
- the dampening solution flows through the filter or filters in this case in the radial direction.
- the fine filtration module is preceded by a coarse filter, which may be arranged, for example, within the circulation line.
- the single figure shows a schematic representation of an embodiment of the dampening solution filter system according to the invention.
- the dampening solution filter system 10 in Fig. 1 is used to clean dampening solution, which is needed to operate the Feutchttechniks an offset printing press, not shown.
- the system 10 comprises a treatment device 12, in whose interior a dampening solution tank 14 is arranged.
- This tank 14 serves to receive and temporarily store the excess dampening solution, which is returned by a return line 16 from the printing machine in the tank 14.
- a feed line 18, which leads from the tank 14 to the outside back to the printing press, is used to supply the filtered dampening solution from the tank 14 to the printing press.
- a feed pump 19 is arranged in the flow line 18.
- a fine filtration module 20 For filtering the recycled dampening solution is a fine filtration module 20, which is also located in the interior of the processing unit 12.
- the fine filtration module 20 is inserted into a cylindrical filter housing 22 which is integrated into the tank 14.
- the filter housing 22 protrudes from above into the tank 14 and is firmly inserted into the ceiling 24 of the tank 14, so that the filter housing 22 including the therein fine filtration module 20 is immersed in the fountain solution 14 located in the tank.
- a recirculation line 26 For passing the fountain solution cached in the tank 14 through the fine filtration module 20 is a recirculation line 26, which opens with one of its ends 28 in the free upper end face 30 of the filter housing 22 and the opposite free end 32 opens into the tank 14 and below the Liquid level of the dampening solution is located.
- the dampening solution With the help of an integrated in the circulation line 26 circulating pump 34, the dampening solution is sucked at the free end 32 of the circulation line 26 and introduced through the circulation line 26 in the fine filtration module 20 so that it flows through the module 20 outwardly back into the tank 14 can.
- a second dampening solution circuit is created in this way, which is independent of the return line 16 and the flow line 18 and thus from the above-described dampening solution circuit between the tank 14 and printing press.
- the flow direction in the recirculation line 26 can be chosen freely. While in the embodiment described herein, the freely projecting into the tank 14 end 32 of the circulation line 26 represents the inlet end 32 and the end of the fine filtration module 20 connected end 28 is the outlet end, the flow direction can also be reversed, so that the dampening solution through the Fine filtration module 20 sucked through and transported by the circulation line 26 to the free end 32.
- a potential absorption filter 36 is arranged in such a manner within the filter housing 22 concentrically around the cylinder axis that the dampening solution, which is introduced by the circulation line 26 from above into the filter housing 22 according to the present design, in the region of the free center axis of the housing 22 freely flow down and the potential absorption filter 36 radially, ie, in the direction of the peripheral surface of the housing 22 can penetrate.
- the cylindrical jacket 38 which forms the circumferential surface of the housing 22, is provided with corresponding openings.
- a likewise approximately cylindrical activated carbon filter can be arranged so that the filters are concentric with one another.
- the activated carbon filter is connected in this way downstream of the potential absorption filter 36 and ensures further filtration of the dampening solution.
- a coarse filter not shown, can be arranged, which performs a pre-filtering of the inflowing into the fine filtration module 20 fountain solution.

Description
Die vorliegende Erfindung betrifft eine Feuchtmittel-Filteranlage für den Feuchtmittelkreislauf einer Offset-Druckmaschine gemäß dem Oberbegriff des Anspruchs 1.The present invention relates to a dampening solution filter system for the dampening solution circuit of an offset printing machine according to the preamble of claim 1.
Filteranlagen der eingangs genannten Art dienen dazu, das Feuchtmittel, das zum Betrieb des Feuchtwerks einer Offset-Druckmaschine in einem Kreislauf gehalten wird, zu reinigen und wieder zur erneuten Verwendung zur Verfügung zu stellen. Die üblichen Filteranlagen umfassen einen Feuchtmittel-Tank, der in ein von der Druckmaschine unabhängiges Aufbereitungsgerät integriert ist. Durch eine Rücklaufleitung wird das überschüssige Feuchtmittel von der Druckmaschine in den Tank rückgeführt, während eine Vorlaufleitung dazu dient, das gefilterte Feuchtmittel vom Tank zur Druckmaschine zu leiten. Zur Reinigung des rückgeführten Feuchtmittels dient ein Feinfiltrations-Modul, das üblicherweise in die Rücklaufleitung integriert ist und einen Potential-Absorptionsfilter umfaßt. Das Reinigungsprinzip dieses Filters beruht darauf, dass die im Feuchtmittel enthaltenen auszufilternden Partikel in der Regel ein negatives elektrisches Zeta-Potential aufweisen und sich daher leicht von einem Absorptionsfilter binden lassen, der mit einem entgegengesetzten, nämlich positiven elektrischen Potential belegt ist.Filter systems of the type mentioned are used to clean the dampening solution, which is kept in a circuit for operating the dampening unit of an offset printing press, and to make available for reuse. The usual filter systems include a fountain solution tank, which is integrated into a separate from the printing machine conditioning device. Through a return line, the excess dampening solution from the printing machine is returned to the tank, while a flow line is used to direct the filtered dampening solution from the tank to the printing press. To clean the returned dampening solution is a fine filtration module, which is usually integrated in the return line and includes a potential absorption filter. The cleaning principle of this filter is based on the fact that the particles to be filtered out contained in the dampening solution generally have a negative electrical zeta potential and can therefore be easily bound by an absorption filter, which is occupied by an opposite, namely positive electrical potential.
Bei den bisher üblichen Feinfiltrations-Modulen handelt es sich um separate Geräteeinheiten, die dem Feuchtmittel-Tank bzw. einem Aufbereitungsgerät, das den Tank enthält, beigestellt sind. Dies führt zu einem erhöhten Platzbedarf und zu einem größeren apparativen Aufwand. Da die Feuchtmittel-Filteranlagen häufig in Bereichen mit beengten Platzverhältnissen eingesetzt werden, stellen zusätzliche Anlagenkomponenten ein besonderes Problem dar. Darüber hinaus verursacht das zusätzliche Gerätemodul erhöhte Kosten der Anlage. Überdies wird bei den herkömmlichen Konstruktionen der Durchsatz des Feuchtmittel-Kreislaufs zwischen Tank und Druckmaschine durch den vergleichsweise kleinen Durchsatz des Feinfiltrations-Moduls begrenzt.The previously used fine filtration modules are separate units which are provided to the dampening solution tank or a treatment device containing the tank. This leads to an increased space requirement and to a greater expenditure on equipment. As the dampening solution filter systems are often used in areas with limited space, additional system components are a particular problem. In addition, the additional device module causes increased costs of the system. Moreover, in the conventional constructions, the throughput of the dampening solution circuit between the tank and the printing machine is limited by the comparatively small throughput of the fine filtration module.
Aufgabe der vorliegenden Erfindung ist es daher, eine Feuchtmittel-Filteranlage der eingangs genannten Art zu schaffen, die kompakter ist als die bisherigen Anlagen und somit den Platzbedarf verringert und kostengünstiger zu installieren ist, und welche ferner einen Durchsatz im Feuchtmittel-Kreislauf zwischen Tank und Druckmaschine ermöglicht, der vom Durchsatz des Feinfiltrations-Moduls unabhängig ist.Object of the present invention is therefore to provide a dampening solution filter system of the type mentioned, which is more compact than the previous systems and thus reduces the space required and cheaper to install, and which also has a throughput in dampening solution circuit between the tank and printing press which is independent of the throughput of the fine filtration module.
Diese Aufgabe wird erfindungsgemäß durch eine Feuchtmittel-Filteranlage mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a dampening solution filter system with the features of claim 1.
Das Feinfiltrations-Modul der erfindungsgemäßen Feuchtmittel-Filteranlage stellt keine separate Geräteeinheit dar, sondern ist in den Tank integriert. Dank dieser Konstruktion wird das Tankvolumen zur Anbringung des Feinfiltrations-Moduls genutzt. Ein separates Beistellgerät ist nicht erforderlich, und die Gesamtkonstruktion ist erheblich kompakter. Zudem ist das Feinfiltrations-Modul nicht in der Rücklaufleitung, sondern von dieser getrennt angeordnet. Entsprechende Einrichtungen der Feuchtmittel-Filteranlage dienen zum Durchleiten des im Tank zwischengespeicherten Feuchtmittels durch das Feinfiltrations-Modul. Der Durchsatz des Feuchmittel-Kreislaufs zwischen Tank und Druckmaschine ist damit unabhängig vom Durchsatz des Moduls.The fine filtration module of the dampening solution filter system according to the invention is not a separate device unit, but is integrated into the tank. Thanks to this design, the tank volume is used to attach the fine filtration module. A separate auxiliary device is not required, and the overall construction is considerably more compact. In addition, the fine filtration module is not located in the return line, but separated from this. Corresponding facilities of the dampening solution filter system serve for passing the fountain solution cached in the tank through the fine filtration module. The throughput of the moisturizer cycle between the tank and the press is thus independent of the throughput of the module.
In einer bevorzugten Ausführungsform umfassen die Einrichtungen zum Durchleiten des Feuchtmittels durch das Feinfiltrations-Modul eine Umwälzleitung, die mit einem Ende an das Modul angeschlossen ist und deren gegenüberliegendes Ende in den Tank mündet.In a preferred embodiment, the means for passing the dampening solution through the fine filtration module comprise a recirculation line which is connected at one end to the module and whose opposite end opens into the tank.
Auf diese Weise wird ein weiterer, vom Feuchmittel-Kreislauf zwischen Tank und Druckmaschine unabhängiger Kreislauf geschaffen, der lediglich zum Umpumpen und Reinigen des im Tank gespeicherten Feuchtmittels dient.In this way, another, independent of the dampening circuit between the tank and printing machine cycle is created, which serves only for pumping and cleaning the fountain solution stored in the tank.
Das Feinfiltrations-Modul ist vorzugsweise entweder am Auslaßende oder am Einlaßende der Umwälzleitung angeordnet.The fine filtration module is preferably located either at the outlet end or at the inlet end of the recirculation line.
Vorzugsweise umfassen die genannten Einrichtungen ferner eine Umwälzpumpe, die in der Umwälzleitung angeordnet ist.Preferably, said means further comprises a circulation pump disposed in the recirculation line.
In einer bevorzugten Ausführungsform umfaßt das Feinfiltrations-Modul einen Aktivkohlefilter, der dem Potential-Absorptionsfilter nachgeschaltet ist.In a preferred embodiment, the fine filtration module comprises an activated carbon filter downstream of the potential absorption filter.
Vorzugsweise sind das Feinfiltrations-Modul und ein gegebenenfalls vorhandener Aktivkohlefilter in ein Filtergehäuse eingesetzt.Preferably, the fine filtration module and an optionally present activated carbon filter are inserted into a filter housing.
Dieses Filtergehäuse ist vorzugsweise etwa zylindrisch ausgebildet, und die Umwälzleitung mündet in eine Stirnseite des Filtergehäuses. Das Feuchtmittel durchströmt den bzw. die Filter in diesem Fall in radialer Richtung.This filter housing is preferably approximately cylindrical, and the recirculation line opens into an end face of the filter housing. The dampening solution flows through the filter or filters in this case in the radial direction.
Vorzugsweise ist dem Feinfiltrations-Modul ein Grobfilter vorgeschaltet, der beispielsweise innerhalb der Umwälzleitung angeordnet sein kann.Preferably, the fine filtration module is preceded by a coarse filter, which may be arranged, for example, within the circulation line.
Im folgenden wird ein bevorzugtes Ausführungsbeispiel der Erfindung anhand der beigefügten Zeichnung näher erläutert.In the following a preferred embodiment of the invention will be described with reference to the accompanying drawings.
Die einzige Figur zeigt eine schematische Darstellung einer Ausführungsform der erfindungsgemäßen Feuchtmittel-Filteranlage.The single figure shows a schematic representation of an embodiment of the dampening solution filter system according to the invention.
Die Feuchtmittel-Filteranlage 10 in
Zur Filtrierung des rückgeführten Feuchtmittels dient ein Feinfiltrations-Modul 20, das sich ebenfalls im Inneren des Aufbereitungsgeräts 12 befindet.For filtering the recycled dampening solution is a
Das Feinfiltrations-Modul 20 ist in ein zylindrisches Filtergehäuse 22 eingesetzt, das in den Tank 14 integriert ist. Im einzelnen ragt das Filtergehäuse 22 von oben in den Tank 14 hinein und ist fest in die Decke 24 des Tanks 14 eingesetzt, so dass das Filtergehäuse 22 einschließlich des darin befindlichen Feinfiltrations-Moduls 20 in das im Tank 14 befindliche Feuchtmittel eingetaucht ist.The
Zum Durchleiten des im Tank 14 zwischengespeicherten Feuchtmittels durch das Feinfiltrations-Modul 20 dient eine Umwälzleitung 26, die mit einem ihrer Enden 28 in die freie obere Stirnseite 30 des Filtergehäuses 22 mündet und deren gegenüberliegendes freies Ende 32 in den Tank 14 mündet und sich unterhalb des Flüssigkeitsspiegels des Feuchtmittels befindet. Mit Hilfe einer in die Umwälzleitung 26 integrierten Umwälzpumpe 34 wird das Feuchtmittel am freien Ende 32 der Umwälzleitung 26 angesaugt und durch die Umwälzleitung 26 in das Feinfiltrations-Modul 20 eingeleitet, so dass es durch das Modul 20 hindurch nach außen wieder in den Tank 14 strömen kann. Durch die an das Feinfiltrations-Modul 20 angeschlossene Umwälzleitung 26 wird auf diese Weise ein zweiter Feuchtmittel-Kreislauf geschaffen, der von der Rücklaufleitung 16 und der Vorlaufleitung 18 und damit von dem oben beschriebenen Feuchtmittel-Kreislauf zwischen Tank 14 und Druckmaschine unabhängig ist. Grundsätzlich kann die Strömungsrichtung in der Umwälzleitung 26 frei gewählt werden. Während bei der hier beschriebenen Ausführungsform das frei in den Tank 14 ragende Ende 32 der Umwälzleitung 26 das Einlaßende 32 darstellt und das an das Feinfiltrations-Modul 20 angeschlossene Ende 28 das Auslaßende ist, kann die Strömungsrichtung auch umgekehrt werden, so dass das Feuchtmittel durch das Feinfiltrations-Modul 20 hindurch angesaugt und durch die Umwälzleitung 26 zum freien Ende 32 befördert wird.For passing the fountain solution cached in the
Ein Potential-Absorptionsfilter 36 ist auf solche Weise innerhalb des Filtergehäuses 22 konzentrisch um dessen Zylinderachse herum angeordnet, dass das Feuchtmittel, das gemäß der hier vorliegenden Konstruktion durch die Umwälzleitung 26 von oben in das Filtergehäuse 22 eingeleitet wird, im Bereich der freien Mittelachse des Gehäuses 22 frei nach unten strömen und den Potential-Absorptionsfilter 36 radial, d. h., in Richtung der Umfangsoberfläche des Gehäuses 22 durchdringen kann.A
Damit ein Austreten des Feuchtmittels in radialer Richtung aus dem Gehäuse 22 ermöglicht wird, ist der zylindrische Mantel 38, der die Umfangsoberfläche des Gehäuses 22 bildet, mit entsprechenden Öffnungen versehen.In order to allow the dampening solution to exit the
Zusätzlich zu dem gezeigten Potential-Absorptionsfilter 36 können weitere Filtereinheiten vorgesehen sein. Insbesondere kann zwischen dem Potential-Absorptionsfilter 36 und dem zylindrischen Mantel 38 des Filtergehäuses 22 ein ebenfalls etwa zylindrischer Aktivkohlefilter angeordnet sein, so dass die Filter konzentrisch ineinander liegen. Der Aktivkohlefilter ist auf diese Weise dem Potential-Absorptionsfilter 36 nachgeschaltet und sorgt für eine weitere Filtrierung des Feuchtmittels. Ferner kann innerhalb der Umwälzleitung 26 ein nicht dargestellter Grobfilter angeordnet sein, der eine Vorfilterung des in das Feinfiltrations-Modul 20 einströmenden Feuchtmittels vornimmt.In addition to the
