Abstract

Metal carrier comprises a metal film having Archimedean spiral contour, powder particles that are regularly arranged between coil windings and are welded to one broad side of the film. An independent claim is included for producing the metal carrier, comprising unwrapping a stained collar metal film, applying the powder particles on one of its broad faces, welding the powder particles at the surface under pressure, optionally heating the film at a higher operating temperature range, catalytically coating the film and the powder particles coated on the film, and winding the film into the Archimedean spiral.

Description

Die Erfindung betrifft Metallkatalysatoren, insbesondere Abgaskatalysatoren, und zwar Bauform und Fertigungsverfahren ihrer Träger.The invention relates to metal catalysts, in particular catalytic converters, namely the design and manufacturing methods of their carrier.

Die bekannten Metallträger sind mit mehrschichtigen Kompositionen gebildet, wobei jede Komposition S-förmig gewickelt ist und aus mehrschichtigen wellenartigen und glatten kartonartig verlöteten Stahlfolien besteht. Die Nachteile dieser Träger sind

  • – Kostspieligkeit seiner Anfertigung wegen der Kompliziertheit der Verwendung der wellenartigen Stahlfolien und deren Verlöten, davon –
  • – Begrenzung der Foliendicke und der Zelldichte,
  • – Teuerung der wellenartigen Folie,
  • – großer Unterschied der Aufheizzeit in den Knoten (diese Zeit bestimmt die Aufheizzeit vom Katalysator) – Verlötstellen der wellenartigen und glatten Stahlfolien – und zwischen ihnen.
The known metal carriers are formed with multi-layered compositions, each composition being wound in an S-shape and consisting of multi-layered wave-like and smooth cardboard-like soldered steel foils. The disadvantages of these carriers are
  • Cost of its manufacture because of the complexity of using the corrugated steel foils and their brazing, of which
  • Limitation of the film thickness and the cell density,
  • - inflation of the wave-like film,
  • - large difference of heating time in the knot (this time determines the heating time of the catalyst) - soldering of wavy and smooth steel foils - and between them.

Erste Aufgabe der Erfindung ist das Erschaffen eines Metallträgers, der rasche und gleichmäßige Aufheizzeit in jedem Ort seines Volumens hat.The first object of the invention is to create a metal carrier which has rapid and uniform heating time in each location of its volume.

Diese Aufgabe wird dadurch gelöst, dass der Metallträger nach DE 10 2006 046 540

  • – eine Metallfolie enthält, Kontur derer Archimedische Spirale darstellt,
  • – zwischen Spiralwindungen derer die Pulverteilchen (aus gleichem Metall wie Metall der Folie) regelmäßig angeordnet sind,
  • – wobei die Pulverteilchen an einer Breitseite der Folie angeschweißt sind.
This object is achieved in that the metal carrier after DE 10 2006 046 540
  • - contains a metal foil, contour of which represents Archimedean spiral,
  • Between spiral turns of which the powder particles (of the same metal as metal of the foil) are regularly arranged,
  • - Wherein the powder particles are welded to a broad side of the film.

Zwecks sicheren Anbringens der Pulverteilchen an die Folie

  • – sind die Grübchen auf einer Breitseite der Folie ausgeführt, Durchmesser derer dem Durchmesser der Pulverteilchen gleich ist, oder/und
  • – ist ein klebender Stoff auf einer Breitseite der Metallfolie aufgetragen.
For the safe attachment of the powder particles to the film
  • - The dimples are carried out on a broad side of the film, diameter equal to the diameter of the powder particles, and / or
  • - An adhesive is applied to a broad side of the metal foil.

Zweite Aufgabe der Erfindung ist das Schaffen eines Fertigungsverfahrens des vorgeschlagenen Trägers, welches niedrigere Fertigungskosten aufweist – sein Herstellen ohne Hochtemperaturlöten.Second object of the invention is to provide a manufacturing process of the proposed carrier, which has lower manufacturing costs - its production without high temperature soldering.

Diese Aufgabe wird dadurch gelöst, dass das Fertigungsverfahren beinhaltet

  • – Auswickeln einer gebeizten Bundmetallfolie,
  • – Auftragen der Pulverteilchen auf eine ihrer Breitflächen,
  • – Schweißen mit Druck der Pulverteilchen an diese Fläche,
  • – gegebenenfalls – Erwärmung der Folie bei höherem Arbeitstemperaturbereich,
  • – katalytische Beschichtung der Folie und der auf sie aufgetragenen Pulverteilchen,
  • – Aufwickeln der Folie in die Archimedische Spirale.
This object is achieved by including the manufacturing process
  • Unwinding a pickled bundled metal foil,
  • Applying the powder particles to one of their broad surfaces,
  • - welding with pressure of the powder particles to this surface,
  • - if necessary - heating the film at a higher working temperature range,
  • Catalytic coating of the film and of the powder particles applied to it,
  • - Winding the foil into the Archimedean spiral.

Da der vorgeschlagene Träger keine Knoten (Kreuzungen) hat, findet rasche, gleichmäßige Aufheizzeit an jedem Ort des Trägerquerschnitts statt.Since the proposed carrier has no nodes (intersections), rapid, uniform heating takes place at each location of the carrier cross-section.

Das Auftragen der Pulverteilchen erfolgt folgendermaßen:

  • – Auswickeln einer Klebefolie (oder einer Papierfolie, auf welche ein klebender Stoff aufgetragen ist), dabei auf ihre klebende Fläche sind die Pulverteilchen aufgetragen,
  • – wobei das Auswickeln der Bundmetall- und der Klebefolie beim Anliegen ihrer Breitflächen erfolgt, so dass das Aufkleben der Pulverteilchen an die Metallfolie stattfindet, und die Klebefolie wird dem Ausbrennen während des Schweißens der Pulverteilchen an die Metallfolie unterzogen.
The application of the powder particles is carried out as follows:
  • Unwinding an adhesive film (or a paper foil on which an adhesive substance is applied), the powder particles being applied to its adhesive surface,
  • Wherein the unwrapping of the bundle metal and the adhesive film takes place in the application of their broad surfaces, so that the sticking of the powder particles takes place on the metal foil, and the adhesive film is subjected to the burnout during welding of the powder particles to the metal foil.

Das Auftragen der Pulverteilchen kann folgendermaßen erfolgen:

  • – Auswickeln einer Klebefolie (oder einer Papierfolie, auf welche ein klebender Stoff aufgetragen ist), dabei auf ihre klebende Fläche sind die Pulverteilchen aufgetragen,
  • – wobei das Auswickeln der Bundmetall- und der Klebefolie beim Anliegen ihrer Breitflächen erfolgt, so dass das Aufkleben der Pulverteilchen an die Metallfolie stattfindet, und die Klebefolie wird dem Ausbrennen während des Schweißens der Pulverteilchen an die Metallfolie unterzogen; oder so, als es auf der dargestellt ist.
The application of the powder particles can be carried out as follows:
  • Unwinding an adhesive film (or a paper foil on which an adhesive substance is applied), the powder particles being applied to its adhesive surface,
  • Wherein the unwrapping of the bundle metal and the adhesive film takes place in the application of their broad surfaces, so that the adhesion of the powder particles takes place on the metal foil, and the adhesive film is subjected to the burnout during welding of the powder particles to the metal foil; or so, as it is on the is shown.

Auf der ist ein Viertel des Trägers dargestellt, auf der ist das Verfahren des Schweißens mit dem Pressen der Pulverteilchen schematisch dargestellt.On the a quarter of the carrier is shown on the the method of welding with the pressing of the powder particles is shown schematically.
