Description

Die Erfindung betrifft eine Vorrichtung zum Aufspritzen von Beiz- oder Spülflüssigkeit auf ein langgestrecktes, metallisches Behandlungsgut, insbesondere Metallband, umfassend in einem Beizbehälter oder dergleichen ober- und/oder unterhalb der Transportebene des Behandlungsgutes in den Behälterwandungen angeordnete, mit Spritzdüsen ausgebildete, an eine Flüssigkeitsversorgung angeschlossene, äußere zylindrische Spritzrohre, wobei das äußere Spritzrohr abgedichtet auf einem Innenrohr angeordnet ist, das mit im Längenabstand der Spritzdüsen des äußeren Spritzrohres in einer Reihe vorgesehenen Öffnungen ausgebildet ist und in situ mit diesen Öffnungen auf das Behandlungsgut weisend sowie mit den Spritzdüsen des äußeren Spritzrohres fluchtend ausgerichtet ist.The invention relates to a device for spraying pickling or rinsing liquid on an elongated, metallic material to be treated, in particular metal strip, comprising in a pickling tank or the like above and / or below the transport plane of the material in the container walls arranged, formed with spray nozzles, to a liquid supply connected, outer cylindrical spray tubes, wherein the outer spray tube is arranged sealed on an inner tube which is formed with provided in the longitudinal distance of the spray nozzles of the outer spray tube in a row openings and pointing in situ with these openings on the treated and with the spray nozzles of the outer spray tube is aligned.

Eine solche Spritzrohranordnung ist durch die BE-A-1 003 788 bekannt geworden, die allerdings dann funktionsunfähig ist, wenn Düsen des starren, äußeren Spritzrohres unbrauchbar geworden sind.Such a spray tube arrangement has become known from BE-A-1 003 788, which, however, is then inoperative when nozzles of the rigid, outer spray tube have become unusable.

Bekannte andere Spritzbeizvorrichtungen für Metallband bestehen aus einem mit einem Deckel versehenen Beizbehälter, der feste oder drehbare Auflager für das in horizontaler Richtung durch den Beizbehälter zu transportierende Behandlungsgut aufweist. Oberhalb und unterhalb der Transportebene sind jeweils mehrere Spritzrohre angeordnet, die an eine Beizflüssigkeitsleitung angeschlossen und mit gegen das Behandlungsgut gerichteten Spritzdüsen versehen sind. Um sicherzustellen, dass die Beizflüssigkeit möglichst gleichmäßig verteilt gegen das Metallband gespritzt wird, dürfen die Düsen bei dem vorhandenen Flüssigkeitsdruck einen vorgegebenen Düsenquerschnitt nicht überschreiten. Mit dem Spritzbeizen geht allerdings einher, dass sich die Spritzdüsen durch Zunder- oder Schlammpartikel, die in der Beizflüssigkeit enthalten sind, zusetzen und damit zwangsläufig die Beizleistung reduzieren. Damit sich verstopfte Spritzdüsen feststellen lassen, ist entweder jedem Spritzrohr oder einer Gruppe von Spritzrohren eine Drucküberwachungseinrichtung zugeordnet. Diese ist so ausgebildet, dass dann, wenn eine oder mehrere Spritzdüsen teilweise oder vollständig verstopft sind, ein durch den damit verbundenen Druckanstieg bewirktes Alarmsignal ausgelöst wird. Die Beizanlage wird daraufhin stillgesetzt, um das Spritzrohr mit den verstopften Spritzdüsen auszuwechseln.Known other metal strip spray pickling devices consist of a pickling container provided with a lid, which has fixed or rotatable supports for the item to be transported in the horizontal direction through the pickling container. Above and below the transport plane in each case a plurality of spray pipes are arranged, which are connected to a pickling liquid line and provided with directed against the treated spray nozzles. To ensure that the pickling liquid is distributed as evenly as possible against the metal strip, the nozzles must be able to withstand the existing liquid pressure do not exceed a given nozzle cross-section. With the Spritzbeizen goes hand in hand, however, that the spray nozzles by Tinder or mud particles that are contained in the pickling liquid, enforce and thus inevitably reduce the pickling performance. So that clogged spray nozzles can be detected, either a pressure sprayer is assigned to each spray pipe or a group of spray pipes. This is designed so that when one or more spray nozzles are partially or completely clogged, caused by the associated increase in pressure alarm signal is triggered. The pickling plant is then shut down to replace the spray tube with the clogged spray nozzles.

Durch die DE 44 09 792 C2 ist es bekannt geworden, an den Außenseiten zweier sich gegenüberliegender Behälterwandungen rohrförmige Anschlussstücke zu befestigen, an denen jeweils ein Spritzrohr mit Spritzdüsen bzw. ein Spritzrohrstutzen angeordnet ist. Die um ihre Längsachse schwenkbaren Spritzrohre sind mit den gegenüber positionierten und jeweils auf einer gemeinsamen Achse liegenden Spritzrohrstutzen über eine gleitfähige und flüssigkeitsdichte Verbindung miteinander verbunden. Die stirnseitig jeweils mit einem Deckel verschlossenen Spritzrohre sind über dessen gegenüber dem Spritzrohrdurchmesser größeren Kreisringfläche an den Flansch eines rohrförmigen Anschlussstückes kraftschlüssig angeschlossen. Obwohl das Auswechseln eines Spritzrohres mit verstopften Spritzdüsen verhältnismäßig schnell durchgeführt werden kann, muss gleichwohl während dieser Zeit die Beizvorrichtung stillgesetzt werden, wodurch die Beizleistung entscheidend beeinträchtigt wird.From DE 44 09 792 C2 it has become known to attach to the outer sides of two opposing container walls tubular fittings, on each of which a spray tube with spray nozzles or a spray nozzle is arranged. The injection pipes, which are pivotable about their longitudinal axis, are connected to one another by way of a sliding and fluid-tight connection with the injection pipe nozzles positioned opposite each and lying on a common axis. The front side each with a lid closed spray tubes are non-positively connected via the opposite of the spray tube diameter annular surface to the flange of a tubular connecting piece. Although the replacement of a spray tube with clogged spray nozzles can be carried out relatively quickly, nevertheless, the pickling device must be stopped during this time, whereby the pickling performance is significantly affected.

Der Erfindung liegt die Aufgabe zugrunde, bei einer Vorrichtung der eingangs genannten Art die Stand- bzw. Betriebszeiten der Spritzrohre zu erhöhen.The invention has for its object to increase in a device of the type mentioned in the stand or operating times of the spray tubes.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass das äußere Spritzrohr um seine Längsachse verstellbar ist, mindestens zwei voneinander beabstandete Düsenreihen aufweist und die Öffnungen des Innenrohres als Langlöcher ausgebildet sind. Selbst dann, wenn sich in diesen Öffnungen Zunder- oder Schlammpartikel ansammeln sollten, ist aufgrund des großen Querschnitts gewährleistet, dass die Flüssigkeit über diese Verteilung doch zu den Spritzdüsen der komplementären Düsenreihe des äußeren Spritzrohres gelangt. Die Ausgestaltung der Öffnungen des Innenrohres als Langlöcher ist auch dann vorteilhaft, wenn das Innenrohr ebenfalls drehbar gelagert wird. Die Verstellbarkeit auch des Innenrohres böte Variationsmöglichkeiten bei der Einstellung des Düsenwinkels zum Behandlungsgut. Ein verwendetes drehbares Innenrohr könnte weiterhin mehr als eine Reihe von Öffnungen besitzen, wobei der Winkelabstand von denen der Düsenreihen des äußeren Spritzrohres abweichen müsste, so dass sich gezielt immer nur eine Düsenreihe mit Flüssigkeit versorgen lässt.This object is achieved in that the outer spray tube is adjustable about its longitudinal axis, at least two spaced nozzle rows and the openings of the inner tube formed as slots are. Even if scale or sludge particles accumulate in these openings, the large cross-section ensures that the liquid still reaches the spray nozzles of the complementary nozzle row of the outer spray tube via this distribution. The configuration of the openings of the inner tube as slots is also advantageous if the inner tube is also rotatably mounted. The adjustability of the inner tube would offer variation possibilities in the adjustment of the nozzle angle to the item to be treated. A used rotatable inner tube could further have more than one row of openings, wherein the angular distance would have to deviate from those of the rows of nozzles of the outer spray tube, so that it is always targeted to supply only one row of nozzles with liquid.

Durch das somit vorliegende Düsenrohr aus zwei konzentrisch ineinander angeordneten Rohren lässt sich erreichen, dass die Zeitintervalle zur Reinigung und Inspektion der Spritzdüsen um die Anzahl der Düsenreihen - vorzugsweise vier im Winkelmaß von 90° vorgesehene Düsenreihen - verlängert wird. Denn entweder wird das gegenüber dem inneren Rohr mittels O-Ringdichtungen abgedichtete äußere Rohr, d. h. Spritzrohr in präventiv festgelegten Zeitabständen oder bei Strömungen mit einer bisher nicht benutzten Düsenreihe in eine Deckungslage mit den Öffnungen des Innenrohres gebracht, die die Beiz oder Spülflüssigkeit auf die Spritzdüsen des äußeren Spritzrohres verteilen. Sofern abweichend von festgelegten Intervallen aufgrund von festgestellten Verstopfungen der Spritzdüsen einer Düsenreihe eine frühere Düsen-Neuorientierung erforderlich sein sollte, geschieht dies in gleicher einfacher Weise durch Verdrehen des äußeren Spritzrohres, bis eine neue, bisher nicht aktive Düsenreihe in Deckungslage mit den Öffnungen des Innenrohres kommt. Dieses Inbetriebbringen einer sauberen Düsenreihe gegen eine vermutlich verschmutzte Düsenreihe kann - je nach Konstruktion - während des Betriebes oder in einem allenfalls kurzen Stillstand der Beizanlage durchgeführt werden.By thus present nozzle tube of two concentric tubes arranged one another can be achieved that the time intervals for cleaning and inspection of the spray nozzles by the number of rows of nozzles - preferably four at 90 ° provided nozzle rows - is extended. Because either the sealed against the inner tube by means of O-ring seals outer tube, ie spray tube placed in preventively fixed intervals or flows with a previously unused row of nozzles in a covering position with the openings of the inner tube, the pickling or rinsing liquid to the spray nozzles of the distribute the outer spray tube. If deviations from specified intervals due to established blockages of the spray nozzles of a row of nozzles a previous nozzle reorientation should be required, this is done in the same simple manner by turning the outer spray tube until a new, not previously active row of nozzles comes in covering position with the openings of the inner tube , This commissioning of a clean row of nozzles against a presumably soiled row of nozzles can - depending on the design - be carried out during operation or in a possibly short shutdown of the pickling unit.

Nach einer Ausführung der Erfindung ist einerseits das äußere Spritzrohr mit einem Behälterflansch drehbar in einer Behälterwandung gelagert und andererseits das Innenrohr an der gegenüberliegenden Behälterwandung angeflanscht und mit der Flüssigkeitsversorgung verbunden. Die somit in einem engen Verbund ineinandergesteckten, jeweils nur einseitig angeflanschten Rohre erlauben nach der vollständigen Ausnutzung aller vorhandenen Düsenreihen auch einen schnellen Austausch des Spritzrohres. Denn dieses braucht lediglich einseitig aus seiner Halterung in der Behälterwandung gelöst und dann von dem Innenrohr abgezogen zu werden. Ein Austauschrohr kann dann sofort auf das in seiner Position verbleibende Innenrohr gesteckt und drehbar angeflanscht werden.According to one embodiment of the invention, on the one hand the outer spray tube with a container flange is rotatably mounted in a container wall and on the other hand, the inner tube flanged to the opposite container wall and connected to the liquid supply. The thus nested in a close association, each only flanged on one side pipes allow for the full utilization of all existing nozzle rows and a quick replacement of the spray tube. Because this only needs to be solved one-sided from its holder in the container and then removed from the inner tube. A replacement tube can then be immediately plugged onto the remaining in its position inner tube and flanged to rotate.

Wenn vorteilhaft Spritz- und Innenrohr jeweils mit den Düsenreihen bzw. der Reihe der Öffnungen zugeordneten Positionsanzeigem versehen sind, kann eine Bedienungsperson sofort erkennen, welche Düsenreihe des äußeren Spritzrohrs momentan den Öffnungen des Innenrohres zugeordnet ist.If advantageous spray and inner tube respectively provided with the rows of nozzles or the row of openings associated Positionsanzeigem, an operator can immediately recognize which nozzle row of the outer spray tube is currently associated with the openings of the inner tube.

Ein nach der Montage und dem Einbau in einen weiter nicht dargestellten Beiz- oder Spülbehälter aus ineinandergesteckten Einzelrohren bestehendes Düsenrohr 1 (vgl. Fig. 3) umfaßt gemäß Fig. 1 ein äußeres Spritzrohr 2 und ein Innenrohr 3. Das Spritzrohr 2 besitzt vier im Winkelabstand von 90° angeordnete, jeweils zahlreiche Spritzdüsen 4 aufweisende Düsenreihen I bis IV (vgl. die Fig. 2 und 3). Das Spritzrohr 4 ist an seinem einen Ende offen und an seinem anderen Ende geschlossen. An dem geschlossenen Ende ist es mit einem vorgelagerten Flansch 5 versehen, der mit einer jeden Düsenreihe I bis IV zugeordneten Positionsanzeigem 6 versehen ist. Mit diesem Flanschende ist das Spritzrohr drehbar am Behälterflansch 7 der einen Behälterwandung 8 gelagert (vgl. Fig. 4).An after insertion and installation in a further not shown pickling or rinsing container of nested single tubes existing nozzle tube 1 (see Fig. 3) comprises, according to Fig. 1, an outer spray tube 2 and an inner tube 3. The spray tube 2 has four at an angular distance arranged from 90 °, each having numerous spray nozzles 4 nozzle rows I to IV (see Figures 2 and 3). The spray tube 4 is open at one end and closed at its other end. At the closed end it is provided with an upstream flange 5 which is provided with a position indicator 6 associated with each nozzle row I to IV. With this flange end, the spray tube is rotatably mounted on the container flange 7 of a container wall 8 (see Fig .. 4).

Das in Fig. 1 unten gezeigte Innenrohr 3 ist mit in einer Reihe angeordneten, im Ausführungsbeispiel als Langlöcher ausgebildeten Öffnungen 9 versehen. Während das in das Spritzrohr 2 eintauchende Ende des Innenrohres 3 mit einem Deckel 10 verschlossen ist, befindet sich an seinem anderen Ende ein Flansch 11, der fest mit der dem Behälterflansch 7 für das äußere Spritzrohr 2 gegenüberliegenden Behälterwandung und dem dortigen Rohrleitungsflansch zur Flüssigkeitsversorgung 12 verbunden ist.The inner tube 3 shown in Fig. 1 below is provided with arranged in a row, in the embodiment designed as elongated holes openings 9. While the immersed in the spray tube 2 end of the inner tube 3 is closed with a lid 10, located at its other end a flange 11 which is firmly connected to the container flange 7 for the outer spray tube 2 opposite container wall and the local pipe flange to the liquid supply 12 is.

Im Betriebszustand umschließt das auf das Innenrohr 3 gesteckte äußere Spritzrohr 4 das Innenrohr 3 mit einem engen, durch O-Ringe abgedichteten Sitz (vgl. Fig. 3). Das Innenrohr 3 wurde zuvor so montiert, daß seine Öffnungen 9 auf das Behandlungsgut (nicht dargestellt) gerichtet sind. Das aufgesteckte äußere Spritzrohr 4 wird danach so verstellt, daß eine der Düsenreihen I bis IV in eine Dekkungslage mit den Öffnungen 9 des Innenrohres 3 kommt, d.h. diese fluchten mit den Spritzdüsen 4 der eingesetzten Düsenreihe, wie in Fig. 3 für die Düsenreihe III gezeigt. Die jeweilige Zuordnung der zum Betrieb gerade verwendeten Düsenreihe ermöglichen die am Flansch 5 des äußeren Spritzrohres 4 angebrachten Positionsanzeiger 6, die bis auf einen die Reihe der Öffnungen 9 des Innenrohres 3 angebenden Positionsanzeiger 13 (vgl. Fig. 4) verstellt werden müssen. Es ist somit in einfacher Weise möglich, entweder in vorbestimmten Zeitintervallen oder bei ermittelten Verstopfungen von Spritzdüsen einer in die Betriebslage gestellten Düsenreihe durch lediglich Verdrehen des äußeren Spritzrohres 4 eine saubere Düsenreihe in Einsatz zu bringen.In the operating state, the outer spray tube 4 placed on the inner tube 3 encloses the inner tube 3 with a narrow seat sealed by O-rings (see FIG. The inner tube 3 has been previously mounted so that its openings 9 are directed to the item to be treated (not shown). The plugged outer spray tube 4 is then adjusted so that one of the nozzle rows I to IV comes in a Dekkungslage with the openings 9 of the inner tube 3, ie they are aligned with the spray nozzles 4 of the nozzle row used, as in Fig. 3 for the nozzle row III shown. The respective assignment of the row of nozzles currently used for operation enable the position indicator 6 attached to the flange 5 of the outer spray tube 4, which need to be adjusted except for a position indicator 13 (see Fig. 4) indicating the row of openings 9 of the inner tube 3. It is thus possible in a simple manner, either at predetermined time intervals or determined blockages of spray nozzles of a nozzle row placed in the operating position by merely rotating the outer spray tube 4 to bring a clean row of nozzles in use.
