Description

Gegenstand der Erfindung ist eine Verbesserung eines durch Patent 928 504 geschützten Rund- und Profildrahtes oder -stabes für technische Siebböden, die aus mindestens zwei Werkstoffen verschiedener Qualität und verschiedener Verschleißfestigkeit bestehen. und bei. dem durch ein in der Technik übliches Mittel der verschleißfestere Werkstoff auf den minderen Werkstoff nur an den Stellen aufgebracht ist, die dem Verschleiß ausgesetzt sind.The subject of the invention is an improvement of a round and profile wire or rod protected by patent 928 504 for technical sieve trays, which consist of at least two materials of different quality and different wear resistance. and at. which, by a means customary in technology, the more wear-resistant material is applied to the lower material only at the points that are exposed to wear.

Siebböden haben allgemein die Aufgabe, einmal. durch die Ausbildung und Gestaltung der Sieböffnungen den Absiebungseffekt zu sichern und zu erhöhen, zum anderen, das Siebgut zu tragen und den dynamischen Beanspruchungen, insbesondere durch die Auftreffwucht des bewegten Siebgutes, standzuhalten. Die Funktion eines Siebbodens wird daher maßgeblich vom Siebstabprofil beeinfluBt. Dies gilt nicht nur für den Durchgangswiderstand und die Tragfähigkeit, sondern auch für die Verschleißfestigkeit. Im Hinblick auf diese Festigkeit hat es sich ergeben, daß- sich im Querschnitt eine doppelte Keulenform als besonders vorteilhaft erweist, wobei der obere Teil der Doppelkeule gemäß dem Hauptpatent aus -dem verschleißfesteren Werkstoff besteht. Diese doppelte Keulenform hat noch den Vorteil, daß der auf die Keule aufg@ebrachte verschleißfestere Werkstoff infolge des Übergreifens der Werkstoffschicht über die Keulenverdickung besonders festhält und selbst bei starken Beanspruchungen nicht abgerissen werden kann.Sieve trays generally have the task of once. through training and design of the sieve openings to secure and increase the screening effect, on the other hand, to carry the material to be screened and the dynamic loads, in particular to withstand the impact of the moving material to be screened. The function of a The sieve bottom is therefore significantly influenced by the sieve rod profile. This does not apply only for volume resistance and load capacity, but also for wear resistance. With regard to this strength, it has been found that there is a cross-section double club shape proves to be particularly advantageous, with the upper part of the Double lobe according to the main patent consists of -the more wear-resistant material. This double club shape has the advantage that the one applied to the club more wear-resistant material due to the overlapping of the material layer over the Thickening of the leg particularly firmly and not even with heavy use can be demolished.

Andererseits hat die doppelte Keulenform im Hinblick auf die Tragfähigkeit den Vorteil großer Widerstandskraft, weil bei dieser Konstruktion die Materialanhäufungen in die Zug- oder Druckzone gelegt sind.On the other hand, the double club shape has in terms of load-bearing capacity the advantage of great resistance, because in this construction the material accumulations are placed in the tension or compression zone.

In. der Zeichnung ist ein Ausführungsbeispiel dargestellt. Mit x ist das Siebstabprofil bezeichnet, das aus weniger verschleißfestem Werkstoff besteht. Dieses Profil hat eine Doppelkeulenform. Auf dem oberen Teil der Keule ist der verschleißfestere Werkstoff 2 aufgebracht, durch den die obere Keule verstärkt und vor Abnützung geschützt wird.In. the drawing shows an embodiment. With x is denotes the Siebstabprofil, which consists of less wear-resistant material. This profile has a double club shape. On the upper part of the club is the more wear-resistant one Material 2 is applied, which reinforces the upper leg and protects it from wear and tear will.
