Abstract

A flat sieve, or a part thereof, has a flat body of elastic material with a rectangular (or square) frame spanned by a plate of lesser depth with a multiplicity of throughgoing parallel slots and intervening rows of shorter slots interrupted by solid transverse webs which are integral with crossbars intersecting only the lower portions of the longer, throughgoing slots. The length of the shorter slots may be about one-tenth that of the longer slots.

Description

Die Erfindung betrifft ein plattenförmiges Siebelement aus elastischem Werkstoff, mit mindestens einem Siebfeld, dessen spaltförmige Sieböffnungen in der Siebebene ununterbrochen etwa über die Länge oder Breite des Siebfeldes verlaufen.The invention relates to a plate-shaped sieve element made of elastic material, with at least one sieve field, the gap-shaped sieve openings in the sieve plane running continuously over the length or width of the sieve field.

Ein derartiges Siebelement ist aus der DE-PS 26 34 934 bekannt. Bei diesem bekannten Siebelement wechseln Reihen kurzer und langer Sieböffnungen einander ab. Ein solches Siebelement weist gute Eigenschaften in seiner Steifigkeit und Spaltgenauigkeit auf, aber könnte eine noch größere offene Siebfläche und eine verbesserte Entwässerungsleistung besitzen.Such a screen element is known from DE-PS 26 34 934. In this known sieve element, rows of short and long sieve openings alternate with one another. Such a screen element has good properties in terms of its rigidity and splitting accuracy, but could have an even larger open screen area and improved drainage performance.

Aufgabe der Erfindung ist es, bei einem Siebelement der eingangs genannten Art die offene Siebfläche zu vergrößern, ohne die Steifigkeit und Spaltgenauigkeit.zu verringern.The object of the invention is to enlarge the open screen area in a screen element of the type mentioned at the outset without reducing the rigidity and splitting accuracy.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daßThis object is achieved in that

zwischen den ununterbrochenen ersten Sieböffnungen jeweils eine Reihe kürzerer spaltförmiger zweiter Sieböffnungen parallel angeordnet ist.a row of shorter, gap-shaped second sieve openings is arranged in parallel between the uninterrupted first sieve openings.

Ein solches Siebelement weist aufgrund der langen ununterbrochenen ersten Sieböffnungen eine sehr große offene Siebfläche auf und besitzt damit eine sehr hohe Entwässerungsleistung. Steifigkeit des Siebelementes und die Spaltgenauigkeit nehmen dabei nicht ab, da die Bereiche der Siebebene, die die zweiten Sieböffnungen einer Reihe voneinander trennen, die Ränder der ersten Sieböffnungen auf beiden Seiten abstützen. Diese Bereiche verhindern somit, daß das zu siebende Gut die Seitenwände der ersten Sieböffnungen nicht verschieben und damit die ersten Sieböffnungen nicht aufweiten kann. Auch erreicht ein in dieser Weise ausgeführtes Siebelement ein geringeres Eigengewicht bei gleicher Trägfähigkeit oder bei gleichem Eigengewicht eine höhere Tragfähigkeit.Such a sieve element has a very large open sieve area due to the long uninterrupted first sieve openings and thus has a very high drainage capacity. The rigidity of the sieve element and the gap accuracy do not decrease, since the regions of the sieve plane that separate the second sieve openings of a row support the edges of the first sieve openings on both sides. These areas thus prevent that the material to be screened does not move the side walls of the first screen openings and thus cannot widen the first screen openings. A sieve element designed in this way also has a lower dead weight with the same load-bearing capacity or a higher load-bearing capacity with the same dead weight.

Aus der DE-OS 30 41 338 ist ein plattenförmiges Siebelement aus elastischem Werkstoff bekannt, dessen Siebfelder nur durchgehend verlaufende spaltförmige Sieböffnungen parallel nebeneinander aufweist. Diese durchgehend verlaufenden Sieböffnungen werden zwar an der Unterseite durch unterhalb der Siebebene liegende Querstege gehalten, aber die in der Siebebene befindlichen Seitenränder der Sieböffnungen können durch das Korn des Siebgutes aufgeweitet werden, sc daß die Spaltgenauigkeit leidet. Dieses bekannte Siebelement weist damit ein ungenügendes Klassierergebnis bei einer Verstopfungsgefahr auf. Das erfindungsgemäße Siebelement kennt dagegen diese Eigenschaften nicht.From DE-OS 30 41 338 a plate-shaped sieve element made of elastic material is known, the sieve fields of which only have gap-shaped sieve openings running parallel next to one another. These continuous sieve openings are held on the underside by transverse webs below the sieve plane, but the side edges of the sieve openings located in the sieve plane can be widened by the grain of the sieved material, so that the splitting accuracy suffers. This known sieve element thus has an insufficient classification result when there is a risk of clogging. In contrast, the sieve element according to the invention does not have these properties.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen aufgeführt.Advantageous embodiments of the invention are listed in the subclaims.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben. Es zeigen:

  • Fig. 1 eine Draufsicht auf einen Teil eines Siebelementes und
  • Fig. 2 einen Schnitt nach II-II in Fig. 1.
An embodiment of the invention is shown in the drawing and will be described in more detail below. Show it:
  • Fig. 1 is a plan view of part of a screen element and
  • 2 shows a section according to II-II in FIG. 1st

Das Siebelement 1 weist eine glatte Oberseite (Siebebene) auf. An der Unterseite stehen zum Teil nicht gezeigte Längs- und Querstege vor, die das Siebelement versteifen. Insbesondere verläuft an der Unterseite an den Rändern rundum ein äußerer Steg 2 zur Versteifung, in dessen Bereich keine Sieböffnungen angeordnet sind.The sieve element 1 has a smooth upper side (sieve plane). On the underside are longitudinal and transverse webs, not shown, which stiffen the sieve element. In particular, an outer web 2 for reinforcement runs around the edges on the underside, in the area of which no screen openings are arranged.

Obwohl das in den Figuren 1 und 2 gezeigte Siebelement 1 nur ein Siebfeld im Ausschnitt zeigt, können mehrere Siebfelder in einem Siebelement angeordnet sein. Das etwa quadratisch ausgeführte Siebfeld besitzt rundum vier Stege 2. Zwischen zwei einander parallelen Stegen 2 sind die Sieböffnungen parallel angeordnet, und zwar erste Sieböffnungen 3 als durchgehend über das gesamte Siebfeld verlaufende Öffnungen und zwischen den Sieböffnungen 3 Reihen 4 von zweiten Sieböffnungen 5, die zueinander alle gleich lang sind und 1/5 bis 1/20, vorzugsweise 1/10 der Länge der ersten Sieböffnungen aufweisen. Damit wechseln Reihen 4 von zweiten Sieböffnungen 5 mit ersten Sieböffnungen einander ab. Die Breiten aller Sieböffnungen sind gleich und im Ausführungsbeispiel ca. 0,5 mm, wobei die Länge der ersten Sieböffnungen ca. 120 mm und die Länge der zweiten Sieböffnungen ca. 12 mm beträgt. Die zwischen den Öffnungen 3 und Reihen 4 befindlichen Siebrestflächen können als Längssteqe 8 bezeichnet werden, die parallel zu den Öffnungen verlaufen.Although the screen element 1 shown in FIGS. 1 and 2 shows only one screen field in the cutout, several screen fields can be arranged in one screen element. The approximately square-shaped sieve field has four webs 2 all around. Between two mutually parallel webs 2, the sieve openings are arranged in parallel, namely first sieve openings 3 as openings running continuously over the entire sieve field and between the sieve openings 3 rows 4 of second sieve openings 5, which are mutually related all of the same length and 1/5 to 1/20, preferably 1/10 of the length of the first screen openings. Rows 4 of second screen openings 5 alternate with first screen openings. The widths of all sieve openings are the same and in the exemplary embodiment are approximately 0.5 mm, the length of the first sieve openings being approximately 120 mm and the length of the second sieve openings approximately 12 mm. The Siebrestflächen located between the openings 3 and 4 rows have the L ängssteqe 8 are referred to, which extend parallel to the openings.

Das zu siebende Gut wird in Richtung des Pfeiles X auf das Siebelement gegeben. Unterhalb der Sieböffnungen 3 und 5 befinden sich quer zur Längsrichtung der öffnungen Querstege 6, deren Oberseiten niedriger liegen als die Siebebene. Die Querstege 6 sind in regelmäßigen Abständen direkt unterhalb der Bereiche 7 der Siebebene angeordnet, die die zweiten Sieböffnungen 5 einer Reihe voneinander trennen. Damit stören die Querstege 6 nicht den Durchfluß durch die zweiten Sieböffnungen 5, während die Querstege 6 und die Bereiche 7 die Seitenwände und die oberen Ränder der ersten Sieböffnungen 3 seitlich stützen.The material to be screened is placed in the direction of arrow X on the screen element. Below the screen openings 3 and 5 are transverse webs 6, the upper sides of which are lower than the screen plane, transverse to the longitudinal direction of the openings. The transverse webs 6 are arranged at regular intervals directly below the areas 7 of the sieve level that separate the second sieve openings 5 of a row. Thus, the crosspieces 6 do not interfere with the flow through the second sieve openings 5, while the crosspieces 6 and the areas 7 laterally support the side walls and the upper edges of the first sieve openings 3.
