Description
Siebboden aus zwischen Tragleisten befestigten gelochten Platten Die Erfindung betrifft einen Siebboden aus sehr harten und verschleißfesten Stoffen, die in Form von einzelnen Platten zwischen Tragleisten verlegt werden.Sieve bottom made of perforated plates fastened between support strips The invention relates to a sieve bottom made of very hard and wear-resistant materials, which are laid in the form of individual panels between support strips.
Es ist bereits bekannt, Siebstäbe zwischen Profilleisten derart beweglich zu verlegen, daß diese unter der Einwirkung der Schwingungen einer Siebmaschine, an einer oberen und unteren Begrenzung anschlagend, in der Normalen zur Siebebene Schwingungen ausführen. Dabei können die Aufschlagstellen der Profilleisten mit elastischen Stoffen.. wie Gummi, versehen sein.It is already known for screen bars to be movable in this way between profile strips to lay that this under the influence of the vibrations of a screening machine, striking at an upper and lower limit, in the normal to the sieve level Perform vibrations. The impact points of the profile strips can with elastic materials like rubber.
Auch ist es bereits bekannt, sehr harte und verschleißfeste Werkstoffe, die bisher in der Siebtechnik wegen ihrer mangelnden Dehnung keine Verwendung finden konnten, durch eine besondere Raumform und die Verbindung dieser Raumform mittels einer plastischen Masse oder eines Klebers zu einer Siebfläche zu vereinigen.It is also already known to use very hard and wear-resistant materials, which have so far not been used in screening technology because of their lack of stretch could, through a special spatial shape and the connection of this spatial shape by means of a plastic mass or an adhesive to unite to form a sieve surface.
Die hier vorliegende Erfindung verwendet zwischen Tragleisten befestigte gelochte Platten mit einer seitlichen Profilierung. Diese Einschnürung wird benutzt, um einen Formkörper oder eine verbundene Anzahl solcher Körper zwischen Tragleisten mittels einer gummielastischen Zwischenlage zu befestigen.The present invention uses fastened between support strips perforated plates with a lateral profile. This constriction is used around a shaped body or a connected number of such bodies between support strips to be attached by means of a rubber-elastic intermediate layer.
Die Figuren zeigen Ausführungsbeispiele des Erfindungsgedankens.The figures show exemplary embodiments of the concept of the invention.
F i g . 1 zeigt gelochte Platten zu glatter Siebfläche, vereinigt in der Draufsicht; F i g. 2 zeigt den Schnitt längs der Linie A -B der Fig. 1; F i g. 3 zeigt gelochte Platten mit über die Siebfläche ragenden Profilleisten; F i g. 4 zeigt den Schnitt längs der Linie C-D der Fi g. 3. F i g. 1 shows perforated plates to form a smooth sieve surface, combined in plan view; F i g. Fig. 2 shows the section along the line A- B of Fig. 1; F i g. 3 shows perforated plates with profile strips protruding over the screen surface; F i g. 4 shows the section along the line CD of FIG . 3.
Die Fig. 1 und 2 zeigen eine geschlossene Siebfläche, bei der die Sieboberfläche nur aus gelochten, durch Zwischenlagen 1 verbundenen Platten 2 besteht, ohne daß die Tragleisten auf der Oberfläche in Erscheinung treten. 1 and 2 show a closed screen surface in which the screen surface consists only of perforated plates 2 connected by intermediate layers 1 , without the support strips appearing on the surface.
Diese Ausführung eignet sich besonders für Feinsiebungen, für Entwässerungsvorgänge und für Zentrifugen-Siebkörbe. Sie kann aber dann nicht angewendet werden, wenn Grobkorn mit einer großen Kornspanne behandelt werden soll.This version is particularly suitable for fine sieving, for dewatering processes and for centrifuge baskets. However, it cannot be used if Coarse grain should be treated with a large grain range.
Eine besondere Art der elastischen Zwischenlage 1 zeigen die F i g. 3 und 4 in Form einer Eckleiste 1 a mit einer Unterschneidung. Diese erlaubt es, die Platten 2 einfach von oben her in die Siebebene einzudrücken.A special type of elastic intermediate layer 1 is shown in FIGS. 3 and 4 in the form of a corner strip 1 a with an undercut. This allows the plates 2 to be simply pressed into the sieve level from above.
Sollen die gegen Schlag und Biegung empfindlichen gelochten Platten 2 bei großen Kornspannen mit grobem Siebgut verwendet werden, so wird die Tragleiste 3 nach oben verlängert. Diese Verlängerung kann als einfache Rechteckleiste 3 c oder als elastische Leiste 3 b ausgebildet sein.If the perforated plates 2, which are sensitive to impact and bending, are to be used for large grain sizes with coarse material to be screened, the support strip 3 is extended upwards. This extension can be used as a simple rectangular strip 3 c or b may be formed as an elastic strip. 3
Schließlich ist es möglich, die Verlängerung der Tragleiste 3 nach oben so auszubilden, daß ein elastisches, nach außen abgerundetes Formprofil 4 auf diese gesetzt werden kann.Finally, it is possible to design the upward extension of the support strip 3 in such a way that an elastic, outwardly rounded shaped profile 4 can be placed on it.
Die hier beschriebene Erfindung ermöglicht das Anwenden gelochter Platten aus spröden, aber hochverschleißfesten Platten nicht nur bei der Fein- und Naßsiebung, sondern nunmehr auch für das ganze Gebiet der Sieb-, Entwässerungs- und Zentrifugentechnik, der Grobsiebung und der Setztechnik.The invention described here enables the use of perforated Plates made of brittle but highly wear-resistant plates not only for fine and Wet sieving, but now also for the entire area of sieving, drainage and centrifuge technology, coarse screening and setting technology.
Das bedeutet, da die keramischen Stoffe auch weitestgehend unempfindlich gegen Säuren und Laugen sind, daß jetzt ganz besonders für die Zentrifugentechnik neue Anwendungsbereiche entstehen, diese waren wegen des hohen Verschleißes, aber auch wegen der Korrosionsanfälligkeit seither verwendeter Stoffe der Trennung mit Hilfe von Siebböden bisher verschlossen.This means that the ceramic materials are also largely insensitive Against acids and alkalis are that now especially for centrifuge technology new areas of application arise, these were due to the high level of wear and tear, however also because of the susceptibility to corrosion of the substances used since then So far closed with the help of sieve trays.
