Abstract
Description
Die Erfindung betrifft einen Gasbrenner, insbesondere zum Beflammen oder Beschichten einer Oberfläche.The invention relates to a gas burner, in particular for flaming or coating a surface.
Zum Beflammen und Beschichten mittels Flamme sind eine Vielzahl von Gasbrennern bekannt geworden. Besonderes Augenmerk liegt bei der Konstruktion solcher Brenner auf der Erzielung einer möglichst homogenen Flamme und einer homogenen Verteilung schichtbildender Substanzen, wie Precursoren, in der Flamme. Ein Homogenisator für der Beschichtung von Oberflächen dienende Gasströme ist in der
Der Erfindung liegt daher die Aufgabe zu Grunde, einen verbesserten Gasbrenner, insbesondere für die Beflammung und Beschichtung von Oberflächen anzugeben.The invention is therefore based on the object to provide an improved gas burner, in particular for the flame treatment and coating of surfaces.
Die Aufgabe wird erfindungsgemäß gelöst durch einen Gasbrenner mit den Merkmalen des Anspruchs 1.The object is achieved by a gas burner with the features of
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.
Ein erfindungsgemäßer Gasbrenner zum Beschichten von Oberflächen umfasst einen Grundkörper, der einen Hohlraum umgibt. Dem Grundkörper ist zumindest ein Brenngas zuführbar. In den Grundkörper ist zumindest ein Metallfolienstapel gasdicht einsetzbar. Der Metallfolienstapel umfasst mindestens zwei erste Metallfolien und mindestens eine zweite Metallfolie. Die erste Metallfolie ist kammartig mit zu einem Gasaustritt hinweisenden Aussparungen und Stegen gebildet. Aus dem Grundkörper ist in die teilweise in den Hohlraum ragenden Metallfolien zumindest Brenngas einströmbar. Im mittels Kraftschluss zusammengehaltenen Metallfolienstapel ist zwischen jeweils zwei ersten Metallfolien jeweils eine zweite Metallfolie eingelegt. Im kraftschlüssig zusammengehaltenen Metallfolienstapel stützen sich die Stege der ersten Metallfolien jeweils auf der benachbarten zweiten Folie ab, die im eingespannten Bereich durchgängig ist. Der Grundkörper weist auf seiner einer zu beflammenden oder zu beschichtenden Oberfläche zugewandten Seite eine Ausnehmung auf, in die der Metallfolienstapel gasdicht eingesetzt wird. Das Brenngas strömt durch die Aussparungen der ersten Metallfolien aus. Der so erzielte Gasstrom ist sehr homogen. Eine Beflammung oder Beschichtung mit dem erfindungsgemäßen Gasbrenner erfolgt auf relativ kurze Distanz, insbesondere in einem Bereich von 1mm bis 20 mm. Der Gasverbrauch gegenüber herkömmlichen Gasbrennern ist dabei erheblich reduziert. Der geringe Abstand bewirkt, dass ein Beflammen der Oberfläche unter Vernachlässigung einer etwaigen Thermik sowohl von oben als auch von unten erfolgen kann. Der geringe Energieverbrauch führt zu einer besonders geringen thermischen Belastung, so dass der Gasbrenner sich kaum verzieht. Zusätzlich verringert sich der erforderliche Aufwand für die Abführung von Abgasen, da entsprechend weniger anfallen. Die erzielten kurzen Flammen sind weniger anfällig für störende Luftströmungen. Die Ausströmcharakteristik des Gasbrenners lässt sich durch die Anzahl erster und zweiter Metallfolien im Metallfolienstapel, die Breite und Anordnung der Aussparungen sowie die Geometrie der Stege der ersten Metallfolie beeinflussen. Vorzugsweise ist eine Anzahl n erster Metallfolien und eine Anzahl n-1 zweiter Metallfolien vorgesehen. Indem der Metallfolienstapel entnommen und in die einzelnen Metallfolien zerlegt wird, kann er im Vergleich mit herkömmlichen kompakten Brennern besonders einfach gereinigt werden. Eine Skalierung des erfindungsgemäßen Brenners auf eine gewünschte Länge, Breite und Form ist konstruktiv auf einfache Weise möglich. Durch den einfachen Aufbau ergeben sich geringe Herstellungskosten.An inventive gas burner for coating surfaces comprises a base body which surrounds a cavity. At least one fuel gas can be supplied to the main body. At least one metal foil stack can be used gas-tight in the base body. The metal foil stack comprises at least two first metal foils and at least one second metal foil. The first metal foil is formed comb-like with pointing to a gas outlet recesses and lands. From the main body at least fuel gas can be flowed into the partially projecting into the cavity metal foils. In held together by traction metal foil stack is between in each case two first metal foils each inserted a second metal foil. In frictionally held together metal foil stack, the webs of the first metal foils are each supported on the adjacent second film, which is continuous in the clamped area. On its side facing a surface to be fired or coated, the main body has a recess into which the metal foil stack is inserted in a gas-tight manner. The fuel gas flows out through the recesses of the first metal foils. The gas stream thus obtained is very homogeneous. Flaming or coating with the gas burner according to the invention takes place at a relatively short distance, in particular in a range from 1 mm to 20 mm. The gas consumption compared to conventional gas burners is considerably reduced. The short distance causes flaming of the surface to occur, ignoring any thermal from both above and below. The low energy consumption leads to a particularly low thermal load, so that the gas burner barely warps. In addition, the required effort for the discharge of exhaust gases is reduced, since correspondingly less. The achieved short flames are less prone to disturbing air currents. The Ausströmcharakteristik of the gas burner can be influenced by the number of first and second metal foils in the metal foil stack, the width and arrangement of the recesses and the geometry of the webs of the first metal foil. Preferably, a number n of first metal foils and a number n-1 of second metal foils are provided. By removing the metal foil stack and separating it into the individual metal foils, it can be cleaned particularly easily in comparison with conventional compact burners. A scaling of the burner according to the invention to a desired length, width and shape is structurally possible in a simple manner. The simple structure results in low production costs.
Erfindungsgemäß weist die zweite Metallfolie in dem in den Hohlraum ragenden Bereich ein Langloch auf, durch das zumindest Brenngas zwischen den Aussparungen der benachbarten ersten Folien strömbar ist. Besonders bei mehr als zwei ersten Metallfolien ist die Versorgung weiter innen liegender erster Folien mit Brenngas nur über die Langlöcher dazwischen liegender zweiter Folien möglich. In jedem Fall erhöht sich auch bei nur zwei ersten Metallfolien die Homogenität der Flamme durch die Verwendung des Langlochs.According to the invention, the second metal foil in the region projecting into the cavity has a slot through which at least fuel gas can flow between the recesses of the adjacent first films. Especially with more than two first metal foils, the supply of further lying inside first films with fuel gas only on the slots of intermediate second films is possible. In any case, even with only two first metal foils, the homogeneity of the flame increases the use of the slot.
In einer bevorzugten Ausführungsform ist der Metallfolienstapel zwischen zwei massiven Haltewangen einspannbar, die gasdicht in den Grundkörper einsetzbar sind. Die Haltewangen sind insbesondere miteinander verschraubbar und so ausgelegt, dass sie sich unter Wärme möglichst nicht verformen. Die Haltewangen bilden mit dem Metallfolienstapel ein einfach in den Grundkörper einsetzbares und wechselbares Modul. Die Haltewangen können entweder nur einen Teil des Metallfolienstapels in der Nähe des Gasaustritts spannen, während ein in den Hohlraum ragender Teil des Metallfolienstapels frei bleibt. Alternativ können die Haltewangen jedoch auch jeweils einen Durchbruch aufweisen, der ein seitliches Einströmen des Brenngases in den Metallfolienstapel ermöglicht.In a preferred embodiment, the metal foil stack can be clamped between two solid retaining cheeks, which can be inserted gas-tight into the base body. The retaining cheeks are in particular screwed together and designed so that they do not deform under heat as possible. The retaining cheeks form with the metal foil stack easy to insert into the body and exchangeable module. The retaining cheeks can either clamp only a part of the metal foil stack in the vicinity of the gas outlet, while a protruding into the cavity part of the metal foil stack remains free. Alternatively, however, the retaining cheeks may also each have an opening which allows lateral inflow of the fuel gas into the metal foil stack.
Eine besonders hohe Homogenität der austretenden Flamme wird erreicht, wenn die Aussparungen benachbarter, von einer zweiten Metallfolie getrennter erster Metallfolien jeweils zueinander versetzt angeordnet sind. Beispielsweise kann der Versatz bei zwei ersten Metallfolien so gestaltet sein, dass immer ein Steg der einen ersten Metallfolie einer Mitte einer Aussparung der anderen ersten Metallfolie benachbart ist. Die Aussparungen und/oder das Langloch werden vorzugsweise mittels Laserschneiden erzeugt, da so einer Gratbildung vorgebeugt wird, die zu unerwünschten Verwirbelungen führen kann.A particularly high homogeneity of the exiting flame is achieved if the recesses of adjacent, separated from a second metal foil first metal foils are each offset from each other. For example, the offset in two first metal foils may be designed such that always one ridge of a first metal foil is adjacent to a center of a recess of the other first metal foil. The recesses and / or the elongated hole are preferably produced by means of laser cutting, since such a burr formation is prevented, which can lead to undesired turbulence.
Zur Befestigung der Metallfolienstapel im Grundkörper oder in den Haltewangen und/oder der Haltewangen im Grundkörper kommen insbesondere lösbare Verbindungen, wie Schrauben in Frage, um die Modularität und einfache Zerlegbarkeit sicherzustellen.For fastening the metal foil stack in the main body or in the retaining cheeks and / or the retaining cheeks in the main body are in particular releasable connections, such as screws in question to ensure the modularity and ease of dismantling.
Für die Beschichtung oder Beflammung einer ungeraden, also nichtebenen Oberfläche sind die dem Gasaustritt zugewandten Seiten der Metallfolien und/oder der Haltewangen und/oder des Grundkörpers vorzugsweise dieser Oberfläche entsprechend geformt, so dass sich keine Inhomogenitäten der Beschichtung ergeben.For the coating or flame treatment of an odd, ie non-planar surface, the sides of the metal foils facing the gas outlet and / or the retaining cheeks and / or the base body are preferably correspondingly shaped, so that no inhomogeneities of the coating result.
Die Metallfolien und/oder die Haltewangen sind vorzugsweise aus Messing und/oder aus Edelstahl gebildet, da diese Materialien auch unter Wärmeeinwirkung nur wenig oxidieren oder sich verformen.The metal foils and / or the retaining cheeks are preferably formed of brass and / or stainless steel, since these materials oxidize or deform only slightly under the action of heat.
Für eine besonders hohe Homogenität der Flamme weisen die Metallfolien jeweils eine Stärke von höchstens 1 mm auf.For a particularly high homogeneity of the flame, the metal foils each have a thickness of at most 1 mm.
Wird der Gasbrenner zum Beschichten genutzt, ist dem Grundkörper vorzugsweise mindestens ein Precursor zuführbar und aus den Aussparungen ausströmbar. Die gute Homogenisierung des Brenngases im Gasbrenner bewirkt auch eine entsprechend homogene Verteilung des Precursors im Brenngas, was wiederum zu einer homogenen Beschichtung führt.If the gas burner is used for coating, preferably at least one precursor can be supplied to the main body and can be flowed out of the recesses. The good homogenization of the fuel gas in the gas burner also causes a correspondingly homogeneous distribution of the precursor in the fuel gas, which in turn leads to a homogeneous coating.
