Description

Siebe aus Stäben, deren Profil einen unteren verhältnismäßig hohen und schmalen Teil sowie einen oberen breiten Kopfteil zeigt, der den eigentlichen Siebspalt abgrenzt Die Erfindung bezieht sich auf Siebe aus Stäben, deren Profil einen unteren verhältnismäßig hohen und schmalen Teil sowie einen oberen breiten Kopfteil zeigt, der den eigentlichen Siebspalt seitlich abgrenzt.Sieves made of bars, the profile of which has a relatively high lower profile and narrow part as well as an upper broad head part, which shows the actual Separating sieve gap The invention relates to sieves made of bars, the profile of which a lower, relatively high and narrow part and an upper broad part Shows the head part, which laterally delimits the actual sieve gap.

Das Neue besteht darin, daß die über der Linie oder Zone des geringsten Abstandes zwischen den Siebstäben liegenden Profilflächenteile giebeldachartig aufstreben.The novelty is that those above the line or zone of the least Strive up the distance between the sieve bars lying profile surface parts like a gable roof.

Hierdurch wird der Vorteil erzielt, daß die obere Begrenzungskante der Durchgangsöffnungen geschützt liegt und die Profilstäbe oder -drähte bis zur vollständigen Abnutzung des Profilkopfes infolge des hohen Steges in Betrieb erhalten werden können, ohne ein Durchbrechen des Siebgutes befürchten zu müssen, wie dieses bei den bekannten Profilen ohne hohen Tragsteg der Fall ist. Das bedeutet gegenüber diesen Profilen eine wichtige Betriebssicherheit und bemerkenswerte Wirtschaftlichkeit wegen der dadurch erreichten langen Betriebsfähigkeit. Der giebeldachförmige Kopf kann hierbei unmittelbar auf den hohen Tragsteg aufgesetzt sein bzw. sich an denselben anschließen, oder es kann zwischen dem hohen Tragsteg und dem giebeldachartig ausgebildeten Profilkopf ein Zwischenstück mit annähernd parallelen Flanken zwischengeschaltet sein, welch letztere Ausführungsform dann noch den Vorteil der Aufrechterhaltung der genauen Spaltweite bei stärkerer Abnutzung der Siebfläche mit sich bringt.This has the advantage that the upper boundary edge the passage openings is protected and the profile rods or wires up to complete wear of the profile head as a result of the high web preserved in operation can be without fear of breaking through the screenings, like this one is the case with the known profiles without a high support web. That means opposite these profiles provide important operational reliability and remarkable economic efficiency because of the long service life achieved as a result. The gabled head can be placed directly on the high support web or on the same connect, or it can be formed between the high support web and the gable roof-like Profile head an intermediate piece with approximately parallel flanks interposed be, which latter embodiment then still has the advantage of maintaining the exact gap width with greater wear of the screen surface.

Gegenüber den Maschen- oder Spaltsieben nach der vorliegenden Erfindung wird der Stand der Technik dahin als bekannt festgestellt, daß i. Profilstäbe oder Profildrähte mit höhen Profilen bekannt sind, bei welchen sich an den hohen Tragsteg ein wulstartiger Profilkopf -ähnlich dem Schienenprofil - anschließt, 2. Profilstäbe in Dreieck- oder Rhombusform, jedoch ohne einen Tragsteg. Die an erster Stelle angeführten Profile haben den Nachteil gegenüber dem giebeldachartigen Profilkopf nach der vorliegenden Erfindung, daß der wulstartige Profilkopf die Siebwirkung ungünstig beein$ußt und die Gefahr des Zusetzens der Spaltöffnungen fördert.Compared to the mesh or wedge wire screens according to the present invention the prior art is determined to be known to the extent that i. Profile bars or Profile wires with high profiles are known, in which the high support web a bead-like profile head - similar to the rail profile - connects, 2nd profile bars in triangular or rhombus shape, but without a support web. The ones listed in the first place Profiles have the disadvantage compared to the gable-roof-like profile head according to the present invention Invention that the bead-like profile head has an unfavorable influence on the screening effect and promotes the risk of clogging of the stomata.

Die an zweiter Stelle genannten Profile (Dreieck- oder Rhombusform) haben den Nachteil, daß ein Durchbrechen des Siebgutes bei Abnutzung auch nur eines Teiles des ohne Tragsteg ausgeführten Profilkopfes eintreten muß.The profiles mentioned in the second place (triangular or rhombus shape) have the disadvantage that the material to be screened will break through when worn Part of the profile head executed without a support web must occur.

Auf der Zeichnung ist die Erfindung in einer beispielsweisen Ausführungsform dargestellt. Wie aus der Zeichnung ersichtlich, ist c der hohe Tragsteg, auf welchen der giebeldachartig ausgebildete Profilkopf - gebildet aus den beiden Profilflächen b, b1 - aufgesetzt ist. Zwischen diesen aus den Profilflächen b, b1 gebildeten Profilkopf und dem hohen Tragsteg kann ein Zwischenstück mit annähernd parallelen Flanken zwischengeschaltet sein, so daß der geringste Abstand zwischen den Siebstäben als Zone ausgebildet ist.In the drawing, the invention is in an exemplary embodiment shown. As can be seen from the drawing, c is the high support web on which the gable-roof-like profile head - formed from the two profile surfaces b, b1 - is attached. Between these profile head formed from the profile surfaces b, b1 and an intermediate piece with approximately parallel flanks can be interposed between the high support web so that the smallest distance between the screen bars is formed as a zone is.

Ohne aus dem Rahmen der Erfindung herauszufallen, kann die obere, in der Mittellinie liegende Hochkante, wie in dem rechtsliegenden Profilstab gestrichelt eingezeichnet, noch etwas abgeflacht sein.Without falling out of the scope of the invention, the upper, upright in the center line, as shown in dashed lines in the profile bar on the right drawn in, should still be flattened a little.
