Description

Die Erfindung betrifft eine Vorrichtung zum Aufspritzen von Beiz- oder Spülflüssigekeit 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 zylindrische Spritzrohre, die um ihre Längsachse verstellbar sind.The invention relates to a device for spraying on pickling or rinsing liquid on an elongated, metallic material to be treated, in particular a metal strip, comprising in a pickling tank or the like above and / or below the transport plane of the material to be treated arranged in the container walls, trained with spray nozzles, connected to a liquid supply cylindrical spray tubes that are adjustable about their longitudinal axis.

Bekannte 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 des 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 spray pickling devices for metal strip consist of one with one Covered pickling tank, the fixed or rotatable support for the horizontal Direction to be transported through the pickling container having. There are several spray tubes above and below the transport level arranged, which is connected to a pickling line and with against the material to be treated is provided with spray nozzles. To ensure, that the pickling liquid is distributed as evenly as possible against the metal strip is sprayed, the nozzles may be one at the existing liquid pressure Do not exceed the specified nozzle cross section. With spray pickling goes hand in hand, however, that the spray nozzles are replaced by scale or sludge particles, which are contained in the pickling liquid, and inevitably the Reduce pickling performance. So that clogged spray nozzles can be determined a pressure monitoring device either for each spray tube or a group of spray tubes assigned. This is designed so that when a or several spray nozzles are partially or completely blocked, one by the associated pressure rise triggered alarm signal is triggered. The pickling line is then stopped to the spray tube with the clogged spray nozzles to replace.

Durch die DE 44 09 792 C2 ist es bekanntgeworden, 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.DE 44 09 792 C2 has made it known, on the outside of two to fasten tubular connecting pieces opposite container walls, on each of which a spray pipe with spray nozzles or a spray pipe socket is arranged. The spray tubes, which can be pivoted about their longitudinal axis, are included the opposite and each lying on a common axis Spray pipe socket via a lubricious and liquid-tight connection with each other connected. The spray tubes, each of which is closed at the end with a lid are larger than the circular ring area compared to the spray tube diameter non-positively connected to the flange of a tubular connecting piece. Although changing a spray tube with clogged spray nozzles can be carried out relatively quickly, nevertheless, during this time the pickling device will be stopped, reducing 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 in a device of the aforementioned Type to increase the service life of the spray pipes.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Spritzrohr mindestens zwei voneinander beabstandete Düsenreihen aufweist und 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 einer Düsenreihe des äußeren Spritzrohres fluchtend ausgerichtet ist. 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.This object is achieved in that the spray tube at least has two spaced apart rows of nozzles and seals on an inner tube is arranged with the in the length distance of the spray nozzles outer spray tube is formed in a row provided openings and pointing in situ with these openings to the material to be treated and with the Spray nozzles of a row of nozzles of the outer spray tube is aligned. Due to the nozzle tube thus present, two concentrically arranged one inside the other Pipes can be reached that the time intervals for cleaning and inspection the spray nozzles by the number of nozzle rows - preferably four in Angle dimension of 90 ° provided nozzle rows - is extended. Because either is sealed against the inner tube by means of O-ring seals outer tube, i.e. Spray tube at preventive intervals or at Currents with a row of nozzles not previously used in a cover position brought the openings of the inner tube that the pickling or rinsing liquid on the Distribute the spray nozzles of the outer spray pipe. If different from specified Intervals due to detected blockages in the spray nozzles Nozzle row an earlier nozzle reorientation should be required happens this in the same simple way by turning the outer spray tube until a new, previously inactive row of nozzles in the cover position with the openings of the Inner tube comes. This putting a clean row of nozzles against a possibly dirty row of nozzles can - depending on the construction - during operation or if the pickling system is at a short standstill become.

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, the outer spray tube is on the one hand with a Container flange rotatably mounted in a container wall and on the other hand flanged the inner tube to the opposite container wall and with connected to the fluid supply. The nested in a tight network, Only allow tubes flanged on one side according to the full utilization of all existing nozzle rows also a quick one Replacement of the spray tube. Because this only needs one-sided from his Bracket released in the container wall and then pulled off the inner tube to become. An exchange pipe can then immediately on the remaining in its position Inner tube inserted and rotatably flanged.

Ein Vorschlag der Erfindung sieht vor, daß 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.A proposal of the invention provides that the openings of the inner tube as Elongated holes are formed. Even if scale or should collect sludge particles is due to the large cross section ensures that the liquid via this distribution after all to the spray nozzles the complementary row of nozzles of the outer spray tube. The design the openings of the inner tube as elongated holes is also advantageous if the inner tube is also rotatably supported. The adjustability of the Inner tube would offer variation options when adjusting the nozzle angle to the material to be treated. A rotatable inner tube could continue to be used have more than one row of openings, the angular distance from which the rows of nozzles of the outer spray tube would have to deviate, so that targeted can only supply one row of nozzles with liquid.

Wenn vorteilhaft Spritz- und Innenrohr jeweils mit den Düsenreihen bzw. der Reihe der Öffnungen zugeordneten Positionsanzeigern 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 each with the nozzle rows or the row of the position indicators associated with openings, an operator can immediately recognize which row of nozzles of the outer spray tube is currently assigned to the openings of the inner tube.
