Description

Die Erfindung betrifft eine Bandreinigungsvorrichtung zum Entfernen von auf einem relativ zur Bandreinigungsvorrichtung bewegten Band befindlichen Verunreinigungen, umfassend eine Sprühkammer zum Aufbringen einer Reinigungsflüssigkeit auf die zu reinigende Bandoberfläche und umfassend eine in Bewegungsrichtung des Bandes der Sprühkammer nachgeschaltete Saugkammer zum Absaugen des auf der Bandoberfläche befindlichen Reinigungsflüssigkeit-Verunreinigungs-Gemisches.The invention relates to a belt cleaning device for removing impurities located on a belt moving relative to the belt cleaning device, comprising a spraying chamber for applying a cleaning fluid to the belt surface to be cleaned and comprising a suction chamber connected downstream in the direction of movement of the belt of the spraying chamber for sucking off the cleaning liquid located on the belt surface. contaminant mixture.

Es hat sich in der Praxis heraus kristallisiert, dass der Reinigungserfolg besser ist, wenn in einer geschlossenen Haube zwei voneinander getrennte Arbeitsbereiche vorgesehen werden, wobei in einem ersten Arbeitsbereich - einer Sprühkammer - eine Reinigungsflüssigkeit auf die zu reinigende Bandoberfläche aufgesprüht und im zweiten Arbeitsbereich - einer Saugkammer - das Reinigungsflüssigkeit-Verunreinigungs-Gemisch abgesaugt wird. Der Reinigungserfolg ist dann wiederum umso besser, je besser die Trennung der beiden Arbeitsbereich gelingt und je besser beide Arbeitsbereiche gegen die Umgebung abgedichtet sind.It has crystallized out in practice that the cleaning success is better when two separate work areas are provided in a closed hood, sprayed in a first working area - a spray chamber - a cleaning liquid on the belt surface to be cleaned and in the second work area - a Suction chamber - the cleaning liquid-impurity mixture is sucked off. The cleaning success is then in turn all the better, the better the separation of the two work area succeeds and the better both work areas are sealed against the environment.

In DE 24 57 708 A1 ist dieses Verfahrensprinzip umgesetzt, wobei in der Vorderwand des Sprühbereichs und in der starren Trennwand zwischen den Arbeitsbereichen Strömungskanäle vorgesehen sind, welche die Reinigungswirkung erheblich reduzieren.In DE 24 57 708 A1 this method principle is implemented, wherein in the front wall of the spray area and in the rigid partition wall between the working areas flow channels are provided which significantly reduce the cleaning effect.

In EP 0 279 729 B1 ist ebenfalls die Trennung des Sprüh- und Saugraums realisiert, wobei hier zwar die in vertikale Richtung starre Trennwand in geringem Abstand über der zu reinigenden Fläche endet, aber beide Arbeitsbereiche sind nicht vollständig gegenüber der Umgebung abgedichtet, so besteht eine Öffnung in der die Sprühkammer einfassenden Haube zur Durchführung der Hochdruckleitungen und die Seitenwände der Saughaube sind nicht mit Dichtleisten versehen. Die beiden Arbeitsbereiche müssen Verfahrens bedingt am Heck eines Fahrzeugs angebracht werden, da vor dem Fahrzeug eine zusätzliche Befeuchtungsanlage vorgesehen ist.In EP 0 279 729 B1 is also the separation of the spray and suction realized, although in the vertical direction rigid partition at a short distance above the surface to be cleaned ends, but both work areas are not completely sealed from the environment, there is an opening in the enclosing the spray chamber Hood for carrying the high-pressure lines and the side walls of the suction hood are not provided with sealing strips. The two work areas must be conditionally attached to the rear of a vehicle because an additional humidification system is provided in front of the vehicle.

In EP 0 773 327 B1 ist ein Reinigungssystem vorgestellt, das die zu den vorbeschriebenen Bandreinigungsvorrichtungen genannten Nachteile nicht aufweist. Beide Arbeitsbereiche dieser Reinigungsvorrichtung sind gegeneinander und gegenüber der Umgebung vollständig abgeschirmt. Nach außen erfolgt eine Abschirmung durch Dichtlippen, die sich am unteren Ende der Sprüh- und Saughaube befinden. Die beiden Kammern sind durch eine in vertikaler Richtung verlaufende starre Querwand getrennt, die dicht oberhalb der zu reinigenden Fläche endet.In EP 0 773 327 B1 a cleaning system is presented which does not have the disadvantages mentioned in relation to the belt cleaning devices described above. Both working areas of this cleaning device are completely shielded from each other and the environment. To the outside, a shielding by sealing lips, which are located at the bottom of the spray and suction hood. The two chambers are separated by a vertically extending rigid transverse wall, which ends just above the surface to be cleaned.

In DE 100 37 548 C2 ist eine Zweikammer-Saughaube angegeben, bei der die Trennwand dicht über der zu reinigenden Fläche endet und an der Haube in Schließrichtung federnd angebrachte Belüftungsklappen vorgesehen sind. Diese Konstruktion dient dazu, in der Haube die Unterdruckverhältnisse selbst regulierend einzustellen.In DE 100 37 548 C2 is a two-chamber suction hood specified in which the partition wall ends tightly over the surface to be cleaned and provided on the hood in the closing direction resiliently mounted ventilation flaps. This construction serves to regulate the negative pressure conditions in the hood itself regulating.

Eine Rollenabdichtung zwischen Gegenständen oder Geräten und einer Fläche ist in DE 199 09 410 C2 veröffentlicht; hier sind frei bewegliche, parallel angeordnete Rollen vorgesehen, die gegenüber einer Lagerachse eine erweiterte Mittelbohrung haben, so dass sie nach oben und unten beweglich sind. Anstelle der Rollen können flache Stäbe mit einem Langloch als Dichtelemente verwendet werden.A roller seal between objects or devices and a surface is in DE 199 09 410 C2 released; Here, freely movable, parallel rollers are provided, which have over a bearing axis an enlarged central bore, so that they are movable up and down. Instead of the rollers flat rods can be used with a slot as sealing elements.

In FR 2 667 087 A1 wird eine Anlage zum Entrosten von Flächen und zur Reinigung von Böden mit Absaugung dargestellt. Auch hier wird in einer Haube aufgedüst und abgesaugt, wobei die Besonderheit besteht, dass ein festes Beizmittel wie z.B. Sand über eine hohe Strömungsgeschwindigkeit mitgerissen wird und dadurch mit hoher Auftreffenergie auf die zu entrostende Fläche trifft (Prinzip Sandstrahlen).In FR 2 667 087 A1 A plant for the rust removal of surfaces and for the cleaning of soils with extraction is presented. Again, in a hood and vacuumed, with the special feature is that a solid mordanting agent such as sand is entrained over a high flow velocity and thus with high impact energy on the surface to be rusted meets (principle sandblasting).

In GM 92 11 401.6 ist ein geschlossenes Hochdruck-Reinigungssystem mit Absaugung beschrieben. In einer Arbeitshaube wird mit Druck eine Flüssigkeit auf die Fläche gebracht und durch eine horizontal rotierende Reinigungswalze auf der Fläche verteilt; gleichzeitig ist in der Haube ein Saugkopf angebracht, der zur Fläche abgedichtet ist.GM 92 11 401.6 describes a closed high-pressure cleaning system with extraction. In a working hood, a liquid is brought to the surface with pressure and distributed by a horizontally rotating cleaning roller on the surface; at the same time a suction head is mounted in the hood, which is sealed to the surface.

Die aus dem Stand der Technik bekannten Vorrichtungen sind nur bedingt zur Reinigung von dünnem Bandmaterial geeignet, da beim Absaugen der auf dem Band gelösten Emulsion das Band selbst mit angesaugt wird. Bei solchen Bändern kann es sich beispielsweise um dünne Stahlbänder handeln, von deren Bandoberfläche anhaftender Zunder entfernt werden soll.The known from the prior art devices are limited suitable for cleaning thin strip material, since the tape itself is sucked in with suction of the dissolved emulsion on the tape. Such bands may be, for example, thin steel bands, from the surface of the tape adhering scale should be removed.

Ausgehend von diesem diskutierten Stand der Technik liegt der Erfindung daher die Aufgabe zugrunde, eine Bandreinigungsvorrichtung der eingangs genannten Art dergestalt weiterzubilden, dass von dieser effektiv das Reinigungsflüssigkeit-Verunreinigungs-Gemisch abgesaugt werden kann, ohne dass zu befürchten ist, dass das zu reinigende Band die saugseitige Öffnung der Saugkammer verschließt.Based on this discussed prior art, the invention is therefore the object of developing a belt cleaning device of the type mentioned in such a way that effectively the cleaning liquid-impurity mixture can be sucked off without this is to be feared that the tape to be cleaned the Suction-side opening of the suction chamber closes.

Diese Aufgabe wird erfindungsgemäß durch eine Bandreinigungsvorrichtung der eingangs genannten, gattungsgemäßen Art gelöst, bei der die Bandreinigungsvorrichtung Bandhaltemittel aufweist, die auf den innerhalb der Saugkammer befindlichen Bandabschnitt wirken und durch welche das Band innerhalb der Saugkammer in einem definierten, über die Breite des Bandes gleichen oder annähernd gleichen Abstand zu der saugseitigen Öffnung gehalten ist.This object is achieved by a belt cleaning device of the aforementioned type, in which the belt cleaning device tape holding means which act on the located within the suction chamber belt section and through which the band within the suction chamber in a defined, the same or the width of the belt is held approximately the same distance to the suction-side opening.

Zum Verhindern eines die Saugöffnung verschließenden Ansaugens des Bandes verfügt diese Bandreinigungsvorrichtung über ein oder mehrere Bandhaltemittel. Diese wirken auf den innerhalb der Saugkammer bzw. unterhalb der Saugöffnung der Saugkammer befindlichen Bandabschnitt. Durch das oder die Bandhaltemittel wird das an der Saugöffnung der Saugkammer vorbeibewegte Band in einem definierten Abstand zu der saugseitigen Öffnung gehalten. Die zur Führung und Beabstandung des Bandes eingesetzten Bandhaltemittel wirken auf das Band. Bei einer gegenüber der Bandoberseite feststehenden Saugkammer wird durch die Bandhaltemittel das Band in dem gewünschten Abstand an der saugseitigen Öffnung der Saugkammer vorbeigeführt. Ebenfalls ist es möglich, die Saugkammer schwimmend anzuordnen, so dass die Bandhaltemittel die Saugkammer oder eine eine Saughaube umfassende Saugkammereinheit relativ zur Bandoberfläche einrichten. Eine solche Saugkammereinheit stützt sich sodann auf der zu reinigenden Oberfläche des Bandes ab. Eine solche Ausgestaltung ist bevorzugt, da bei dieser eine selbsttätige Anpassung an unterschiedlichen Banddicken erfolgt.To prevent suction of the band closing the suction opening, this band cleaning apparatus has one or more band holding means. These act on the band section located inside the suction chamber or below the suction opening of the suction chamber. By the tape holding means or the band moved past the suction opening of the suction chamber is held at a defined distance from the suction-side opening. The tape holding means used for guiding and spacing the tape act on the tape. In a suction chamber which is stationary relative to the upper side of the band, the band is guided past the suction-side opening of the suction chamber by the band-holding means at the desired spacing. It is also possible to arrange the suction chamber in a floating manner, so that the band holding means set up the suction chamber or a suction chamber unit comprising a suction hood relative to the strip surface. Such a suction chamber unit is then supported on the surface of the belt to be cleaned. Such an embodiment is preferred, since in this an automatic adjustment takes place at different strip thicknesses.

Die vorbeschriebenen Bandhaltemittel können die Bandoberfläche berührend oder auch berührungsfrei arbeitend ausgelegt sein. Berührende Bandhaltemittel sind beispielsweise ein oder mehrere bezüglich ihrer Drehachse quer zur Bandtransportrichtung verlaufende und sich über die Breite des Bandes erstreckende Rollen. Diese Rollen sind Teil einer eine Saughaube umfassenden Saugkammereinheit und bilden den bandseitigen Abschluss der Saugkammereinheit. Somit stützt sich gemäß dieser Ausgestaltung die Saugkammereinheit mit der oder den Rollen auf der Oberseite des zu reinigenden Bandes ab. Um einen Durchlass von Reinigungsflüssigkeit-Verunreinigungs-Gemisch durch eine in Transportrichtung des Bandes gesehen eingangsseitige Rolle hindurchzuverbessern, ist gemäß einem Ausführungsbeispiel vorgesehen, eine solche Rolle aus mehreren Rollensegmenten aufzubauen, zwischen welchen Rollensegmenten jeweils ein Spalt angeordnet ist. Anstelle des Vorsehens einzelner Rollensegmente zum Aufbau einer solchen Rolle kann grundsätzlich auch eine durchgängige Rolle vorgesehen sein, in die umfänglich mit Abstand umlaufende Nuten eingebracht sind.The tape holding means described above may be designed to be touching the tape surface or working without contact. Contacting belt-holding means are, for example, one or more rollers extending transversely to the belt transport direction with respect to their axis of rotation and extending over the width of the belt. These rollers are part of a suction hood unit comprising a suction hood and form the belt end of the suction chamber unit. Thus, according to this embodiment, the suction chamber unit is supported by the roller (s) on the upper side of the belt to be cleaned. In order to improve a passage of cleaning fluid-impurity mixture through an input-side roller as seen in the transport direction of the belt, it is provided according to an exemplary embodiment to construct such a roller from a plurality of roller segments, between each of which roller segments a gap is arranged. Instead of providing individual roller segments for constructing such a roller, in principle, a continuous roller can also be provided, in which circumferentially spaced circumferential grooves are introduced.

Anstelle einer die Bandoberseite berührenden Ausgestaltung der Bandhaltemittel können diese auch berührungslos konzipiert sein. Ein berührungsloses Bandhaltemittel ist beispielsweise ein quer zur Bandtransportrichtung angeordneter Düsenbalken mit mehreren über die Breite des Bandes verteilt angeordneten Düsenöffnungen. Bei einem Vertrieb der Bandreinigungsvorrichtung ist der Düsenbalken mit einem unter Druck stehenden Fluid, etwa Druckluft beaufschlagt. Das aus dem Düsenbalken unter Druck austretende Fluid bildet sodann ein Fluidkissen, beispielsweise ein Luftkissen aus, welches verhindert, dass das zu reinigende Band die Saugöffnung der Saugkammer verschließen kann. Das unter Druck aus einem solchen Düsenbalken austretende Fluid kann zudem den Reinigungsvorgang aufgrund der auf diesem Wege auf die zu reinigende Bandoberfläche wirkenden kinetischen Energie unterstützen. Möglich ist ebenfalls eine Kombination von berührend und berührungsfrei ausgelegten Bandhaltemitteln. Eine solche Kombination bietet sich bei Ausgestaltungen an, bei denen die in Transportrichtung des Bandes gesehen saugkammereingangsseitig eine Rolle als erstes Bandhaltemittel angeordnet ist und der untere Abschluss der Saughaube ausgangsseitig der Saugkammer eine Düsenkontur aufweist. Bei einer solchen Ausgestaltung ist üblicherweise kein Raum für eine ausgangsseitige Rollenabstützung vorhanden. Sollte ausgangsseitig eine Bandabstützung gewünscht sein, kann diese unter Verwendung eines Düsenbalkens, wie vorbeschrieben, realisiert werden. Der Düsenbalken einer solchen Ausgestaltung würde sich dann zweckmäßigerweise außerhalb der Saughaube und somit vor dem durch die Düsenkontur gebildeten Eingang angeordnet sein.Instead of a band top contacting the design of the tape holding means they can also be designed without contact. A non-contact tape holding means is, for example, a nozzle bar arranged transversely to the tape transport direction and having a plurality of nozzle openings distributed over the width of the tape. In a distribution of the belt cleaning device of the nozzle beam with a pressurized fluid, such as compressed air is applied. The fluid emerging from the nozzle bar under pressure then forms a fluid cushion, for example an air cushion, which prevents the band to be cleaned from closing the suction opening of the suction chamber. The fluid exiting under pressure from such a nozzle bar can also support the cleaning process due to the kinetic energy acting in this way on the strip surface to be cleaned. Also possible is a combination of touching and non-contact designed tape holding means. Such a combination lends itself to embodiments in which viewed in the transport direction of the belt suction chamber inlet side, a roller is arranged as the first belt holding means and the lower end of the suction hood on the output side of the suction chamber a Has nozzle contour. In such an embodiment, there is usually no room for an output side roller support. If a band support is desired on the output side, this can be realized using a nozzle beam as described above. The nozzle bar of such a configuration would then expediently be arranged outside the suction hood and thus before the inlet formed by the nozzle contour.

Die Düsenkontur selbst ist zweckmäßigerweise als Beschleunigungsdüse ausgebildet, und zwar in die Saugkammer hinein wirkend. Das Anordnen eines Düsenbalkens düseneingangsseitig, in Strömungsrichtung der durch die Düsenkontur bei einem Betrieb der Bandreinigungsvorrichtung strömenden Luft gesehen, kann insbesondere, wenn der Ausgang der Düsen des Düsenbalkens in Richtung zum Düseneingang hin geneigt ist und somit das den Düsenbalken beaufschlagende Fluid in Richtung zur Saugkammer hin geneigt auf die Oberfläche des zu reinigenden Bandes trifft, unterstützt durch die durch die Düsenkontur einströmende Luft, unterstützend zum Entfernen von sämtlichen von der Bandoberfläche gelösten Verunreinigungen sowie die gesamte aufgebrachte Reinigungsflüssigkeit wirken. Grundsätzlich kann ebenfalls vorgesehen sein, die Bandhaltemittel magnetisch auszulegen. Derartige Bandhaltemittel können jedoch nur dann eingesetzt werden, wenn das zu reinigende Band ferromagnetische Eigenschaften aufweist. Bei diesem Konzept ist vorgesehen, durch Anordnung entsprechender Magnete das zu reinigende Band mit Abstand zu der Saugöffnung der Saugkammer weg zu halten.The nozzle contour itself is expediently designed as an acceleration nozzle, namely acting into the suction chamber. The arrangement of a nozzle bar nozzle-side, as seen in the flow direction of the air flowing through the nozzle contour during operation of the belt cleaning device, in particular, when the output of the nozzle of the nozzle beam is inclined towards the nozzle inlet and thus the fluid acting on the nozzle beam in the direction of the suction chamber inclined to the surface of the belt to be cleaned, assisted by the air flowing in through the nozzle contour, assisting in the removal of all of the belt surface dissolved impurities and the entire applied cleaning liquid act. In principle, it may also be provided to design the band holding means magnetically. However, such tape holding means can only be used if the tape to be cleaned has ferromagnetic properties. In this concept, it is provided to keep the band to be cleaned at a distance from the suction opening of the suction chamber by arranging corresponding magnets.

Bei einer schwimmenden oder anderweitigen höheneinrichtbaren Anordnung der Saugkammereinheit kann dieses durch das Eigengewicht der Saugkammereinheit, durch Federkraft und/oder durch die auf das Band anwirkende Ansaugkraft bereitgestellt werden. Grundsätzlich ist für die Höheneinstellbarkeit der Saugkammer keine aufwendige Mechanik oder Hydraulik notwendig.In a floating or otherwise höheneinrichtbaren arrangement of the suction chamber unit, this can be provided by the weight of the suction chamber unit, by spring force and / or by the force acting on the tape suction force. Basically, no complicated mechanics or hydraulics is necessary for the height adjustability of the suction chamber.

Zum Entzundern der Oberfläche eines Stahlbandes 10 dient eine Bandreinigungsvorrichtung B. Die Bandreinigungsvorrichtung B ist an der Oberseite bezüglich des zu reinigenden Bandes 10 angeordnet. Bei dem zu reinigenden Band 10 handelt es sich um ein dünnes Stahlband. Die Bandreinigungsvorrichtung B verfügt über eine Haube 1. Innerhalb der Haube 1 ist eine Sprühkammer 2 angeordnet.For descaling the surface of a steel strip 10 is a belt cleaning device B. The belt cleaning device B is arranged at the top with respect to the belt 10 to be cleaned. The belt 10 to be cleaned is a thin steel belt. The belt cleaning device B has a hood 1. Within the hood 1, a spray chamber 2 is arranged.

Innerhalb der Haube 1 wird in der Sprühkammer 2 über eine Hohlwelle 5 und den rotierenden Düsenbalken 6 mit einer Düse 11 ein Wasser-Reinigungsmittel-Gemisch auf die zur Bandreinigungsvorrichtung B weisende Oberfläche des zu reinigenden, sich in Pfeilrichtung bewegenden Bandes 10 gedüst. Dabei wird ein gerichteter Sprühstrahl 12 auf die Bandoberfläche generiert. Die auf dem Band 10 entstehende Schmutzemulsion wird in einer gleichfalls von der Haube 1 eingefassten Saugkammer 3 über einen Absaugkanal 4 abgesaugt. Die Sprühkammer 2 ist von dem Bereich der Haube 1, der die Sprühkammer 2 aufnimmt, durch einen feststehenden Steg 9 nach Art einer Querwand getrennt. In dem der Saugkammer 3 zugeordneten Bereich der Haube 1 ist eine eine Saughaube 13 umfassende Saugkammereinheit angeordnet. An der Saughaube 13 sind außenseitig Führungsstäbe 14 angeordnet, die die Oberseite der Haube 1 durchgreifen und in Halterungen 15 der Haube 1 geführt sind. Auf diese Weise ist die Saugkammereinheit innerhalb des der Saugkammer 3 zugeordneten Bereiches der Haube 1 in vertikaler Richtung, wie durch den Doppelpfeil angedeutet, bewegbar.Within the hood 1 in the spray chamber 2 via a hollow shaft 5 and the rotating nozzle bar 6 with a nozzle 11, a water-cleaning agent mixture on the belt cleaning device B facing surface of the cleaned to be cleaned, moving in the direction of arrow tape 10. In this case, a directed spray jet 12 is generated on the strip surface. The resulting on the tape 10 dirt emulsion is sucked in a likewise enclosed by the hood 1 suction chamber 3 via a suction channel 4. The spray chamber 2 is separated from the region of the hood 1, which receives the spray chamber 2, by a fixed web 9 in the manner of a transverse wall. In which the suction chamber 3 associated region of the hood 1 is a suction hood 13 comprehensive suction chamber unit is arranged. On the suction hood 13 outside guide rods 14 are arranged, which pass through the top of the hood 1 and are guided in brackets 15 of the hood 1. In this way, the suction chamber unit within the suction chamber 3 associated region of the hood 1 in the vertical direction, as indicated by the double arrow, movable.

Teil der Saugkammereinheit sind zwei bezüglich ihrer Drehachse quer zur Transportrichtung des Bandes 10 angeordnete Rollen 7, 7'. Die Rollen 7, 7' sind an die Saughaube 13 angeschlossen und bilden die bandseitige Abstützung der Saugkammereinheit.Part of the suction chamber unit are two with respect to their axis of rotation transversely to the transport direction of the belt 10 arranged rollers 7, 7 '. The rollers 7, 7 'are connected to the suction hood 13 and form the band-side support of the suction chamber unit.

Die Saugkammer 3 des dargestellten Ausführungsbeispiels wird somit maßgeblich durch die Saughaube 13 und die Rollen 7, 7' gebildet. Verschlossen ist die Saugkammer 3 unterseitig durch das Band 10. Zwischen den Rollen 7, 7' und dem bandseitigen Abschluss der Saughaube 13 befindet sich jeweils ein Spalt, durch den bei einem Betrieb der Bandreinigungsvorrichtung B ebenfalls Reinigungsflüssigkeit-Verunreinigungs-Gemisch hindurchtritt und durch den Absaugkanal 4 weggeführt wird.The suction chamber 3 of the illustrated embodiment is thus significantly formed by the suction hood 13 and the rollers 7, 7 '. Between the rollers 7, 7 'and the band-side completion of the suction hood 13 is in each case a gap through which passes during an operation of the belt cleaning device B also cleaning liquid-impurity mixture and through the suction channel 4 is led away.

Der Abstand der beiden Rollen 7, 7' der Saugkammereinheit ist möglichst gering. Die Beabstandung der Rollen 7, 7' ist so gewählt, dass bei einem Betrieb der Bandreinigungsvorrichtung B das Band nicht in den zwischen den beiden Rollen 7, 7' befindlichen Spalt eingezogen wird. In Abhängigkeit von der Erstreckung der Saughaube 13 in Transportrichtung des Bandes 10 wird man daher den Durchmesser der Rollen 7, 7' und deren Abstand zueinander entsprechend einstellen. Bei einem Betrieb der Bandreinigungsvorrichtung B dienen die zwischen den Rollen 7, 7' und dem bandseitigen Abschluss der Saughaube 13 vorgesehenen Spalte auch dem Zweck, dass ein vollständiger Verschluss der saugseitigen Öffnung der Saugkammer 3 durch die zu reinigende Oberfläche des Bandes 10 nicht eintritt.The distance between the two rollers 7, 7 'of the suction chamber unit is as small as possible. The spacing of the rollers 7, 7 'is selected such that during operation of the belt cleaning device B, the belt is not drawn into the gap between the two rollers 7, 7'. Depending on the extension of the suction hood 13 in the transport direction of the belt 10, therefore, one will adjust the diameter of the rollers 7, 7 'and their distance from each other accordingly. During operation of the belt cleaning device B, the gaps provided between the rollers 7, 7 'and the belt-side closure of the suction hood 13 also serve the purpose that complete closure of the suction-side opening of the suction chamber 3 does not occur through the surface of the belt 10 to be cleaned.

Figur 2 zeigt die Saugkammereinheit der Figur 1 in einer perspektivischen Darstellung. Erkennbar ist, dass die Rollen 7, 7' Teil der Saugkammereinheit sind. Gelagert sind die Rollen 7, 7' in jeweils einer stirnseitigen Lagerplatte 18, 18'. FIG. 2 shows the suction chamber unit of FIG. 1 in a perspective view. It can be seen that the rollers 7, 7 'are part of the suction chamber unit. Are stored, the rollers 7, 7 'in each case a front-side bearing plate 18, 18'.

Lediglich zur Führung des Bandes 10 ist in der Sprühkammer 2 eine weitere Rolle 19 angeordnet.Only for guiding the band 10, a further roller 19 is arranged in the spray chamber 2.

Da bei dem Band 10 beide Oberseiten gleichzeitig gereinigt werden sollen, befindet sich an der Unterseite des Bandes 10 eine weitere Bandreinigungsvorrichtung B', die identisch aufgebaut ist wie die Bandreinigungsvorrichtung B. Dieses hat nicht nur zum Vorteil, dass beide Bandoberflächen gleichzeitig gereinigt werden können, sondern dass zudem eine Bandführung durch die in Bezug auf die Ebene des Bandes einander spiegelbildlich gegenüberliegenden Rollen 7, 7', 19 das Band innerhalb der durch die beiden Bandreinigungsvorrichtungen B, B' gebildeten Einrichtung definiert geführt ist. Die Saugkammereinheiten der beiden Bandreinigungsvorrichtungen B, B' stützen sich bei dem dargestellten Ausführungsbeispiel mit einer gewissen Federvorspannung über ihre Rollen 7, 7' auf der jeweiligen Bandoberfläche ab. Zum Ausüben eines gewissen Anpressdruckes können auch pneumatische Stellmittel eingesetzt werden.Since both tops are to be cleaned at the same time in the band 10, there is another band-cleaning device B 'on the underside of the band 10, which is constructed identically to the band-cleaning apparatus B. This not only has the advantage that both band surfaces can be cleaned simultaneously, but that also a tape guide by the respect to the plane of the tape each other in mirror image opposite rollers 7, 7 ', 19, the band within the device defined by the two belt cleaning devices B, B 'is guided defined. The suction chamber units of the two belt cleaning devices B, B 'are supported in the illustrated embodiment with a certain preload on their rollers 7, 7' on the respective belt surface. To exert a certain contact pressure and pneumatic adjusting means can be used.

Die beiden Bandreinigungseinrichtungen B, B' der Figur 1 sind lediglich im Wege eines Beispiels in horizontaler Richtung angeordnet. Selbstverständlich ist es möglich, die Bandreinigungsvorrichtungen in jegliche beliebige Raumlage zu bringen, so dass diese quasi an beliebiger Stelle einer Bandführung angeordnet werden können. Der durch die Absaugkanäle 4 jeweils erzeugte Unterdruck in den Saugkammern ist ausreichend groß, dass unabhängig von der Raumlage der Bandreinigungsvorrichtungen B, B' das Reinigungsflüssigkeit-Verunreinigungs-Gemisch wirksam abgesaugt wird und die Oberflächen des Bandes 10 sauber und trocken aus den Bandreinigungsvorrichtungen B, B' heraustreten.The two belt cleaning devices B, B 'of FIG. 1 are arranged only by way of example in the horizontal direction. Of course, it is possible to bring the belt cleaning devices in any spatial position, so that they can be arranged virtually anywhere on a tape guide. The negative pressure in the suction chambers produced by the suction channels 4 is sufficiently large that the cleaning liquid-impurity mixture is effectively sucked off regardless of the spatial position of the belt cleaning devices B, B 'and the surfaces of the belt 10 are clean and dry from the belt cleaning devices B, B ' stepping out.

Mit den durch das Bezugszeichen 8 zugehörigen Pfeilen sind bezüglich der Bandreinigungsvorrichtung B Luft- und Reinigungsflüssigkeit-Verunreinigungs-Gemisch Wegsamkeiten markiert. Bei einem Betrieb der Bandreinigungsvorrichtung B - gleiches gilt für die Bandreinigungsvorrichtung B'- wird über den Düsenbalken 6 unter Druck stehende Reinigungsflüssigkeit auf die Oberfläche des Bandes 10 aufgesprüht. Anhaftender Zunder oder auch andere Verunreinigungen werden gelöst und treten durch den zwischen der Rolle 7' und der Saughaube 13 befindlichen Spalt sowie zwischen der Unterseite der Rolle 7' und der Bandoberseite hindurch in die Saugkammer 3 ein. Die Rolle 7' ist zu diesem Zweck aus einzelnen Rollensegmenten aufgebaut. Zwischen jedem Rollensegment ist ein Spalt, so dass zwischen den Rollensegmenten und unter den Rollensegmenten hindurch in Richtung zur Saugkammer 3 Reinigungsflüssigkeit-Verunreinigungs-Gemisch in die Saugkammer 3 hindurchtreten kann. Infolge des an dem Absaugkanal 4 anliegenden Unterdruckes wird die in der Saugkammer 3 befindliche Emulsion aus dieser abgesaugt. Der Absaugprozess wird unterstützt durch von der Außenseite unter der Wand 16 der Haube 1 eintretende Luft, die sowohl durch den zwischen der Rolle 7 und dem ausgangsseitigen Abschluss der Saughaube 13 gebildeten Spalt sowie zwischen der Rolle 7 und der Oberfläche des Bandes 10 hindurch eintretende Luft unterstützt.With the arrows associated with the reference numeral 8 are marked with respect to the belt cleaning device B air and cleaning fluid impurity mixture pathways. In an operation of the belt cleaning device B - the same applies to the belt cleaning device B '- on the nozzle bar 6 pressurized cleaning liquid is sprayed onto the surface of the belt 10. Adherent scale or other impurities are released and pass through the gap between the roller 7 'and the suction hood 13 and between the underside of the roller 7' and the upper side of the tape into the suction chamber 3. The roller 7 'is constructed for this purpose from individual roller segments. Between each roller segment is a gap, so that between the roller segments and under the roller segments in the direction of the suction chamber 3 cleaning fluid-impurity mixture can pass into the suction chamber 3. As a result of the vacuum applied to the suction channel 4, the emulsion located in the suction chamber 3 is sucked out of it. The suction process is assisted by entering from the outside under the wall 16 of the hood 1 air, both by the gap formed between the roller 7 and the output side of the suction hood 13 and supports air entering between the roller 7 and the surface of the belt 10.

Figur 3 zeigt ein weiteres Ausführungsbeispiel einer Bandreinigungsvorrichtung B". Die Bandreinigungsvorrichtung B" ist grundsätzlich aufgebaut wie die zuvor beschriebene Bandreinigungsvorrichtung B. Daher sind gleiche Teile mit gleichen Bezugszeichen gekennzeichnet. Im Unterschied zu der Bandreinigungsvorrichtung B weist die Bandreinigungsvorrichtung B" am Ausgang ihrer Saughaube 13 an ihren unterseitigen Abschluss zum Band 10 hin eine Düsenkontur 17 auf. Die Düsenkontur 17 ist nach Art einer Beschleunigungsdüse, hier: als Lavaldüse, ausgebildet. Durch die Maßnahme wird in besonders effektiver Weise ein in die Saugkammer 3 hineinströmender Luftstrom generiert, der den Abtrocknungsvorgang beim Absaugen unterstützt. Die Düse ist letztendlich gebildet durch den Abstand der Oberseite des Bandes 10 von der Düsenkohtur 17 der Saughaube 13. Typischerweise ist der durch die Düse strömende Luftstrom stärker als die auf das Band 10 wirkende Absaugkraft. Damit gewährleistet der in die Saugkammer einströmende Luftstrom zudem, dass das Band 10 nicht an der Düsenkontur 17 zur Anlage gelangt. FIG. 3 shows another embodiment of a belt cleaning device B ". The belt cleaning device B" is basically constructed like the belt cleaning device B described above. Therefore, like parts are designated by like reference numerals. In contrast to the belt cleaning device B, the belt cleaning device B "has a nozzle contour 17 at the bottom of its suction hood 13. The nozzle contour 17 is designed like an accelerating nozzle, here as a Laval nozzle The nozzle is ultimately formed by the distance of the top of the belt 10 from the nozzle cooktop 17 of the suction hood 13. Typically, the airflow passing through the nozzle is stronger than the suction force acting on the belt 10. In addition, the air flow flowing into the suction chamber ensures that the belt 10 does not come to bear against the nozzle contour 17.

Die Abstützung der Saugkammereinheiten auf der Oberseite des Bandes 10 kann auch dergestalt vorgesehen sein, dass das an der saugseitigen Öffnung einer Saugkammer vorbeitransportierte Band flattert. Ein solches Flattern kann den Absaugvorgang unterstützen.The support of the suction chamber units on the upper side of the belt 10 can also be provided in such a way that the belt conveyed past the suction-side opening of a suction chamber flutters. Such fluttering may assist the aspiration process.

Bei den beschriebenen Ausführungsbeispielen ist die Bandreinigungsvorrichtung stationär angeordnet und das zu reinigende Band an dieser vorbeitransportiert worden. Gleichermaßen kann zum Erzielen desselben Zweckes auch die Bandreinigungsvorrichtung gegenüber dem Band transportiert werden.In the described embodiments, the belt cleaning device is arranged stationary and the belt to be cleaned has been transported past this. Likewise, to achieve the same purpose, the belt cleaning device can also be transported relative to the belt.
