Abstract

Bei diesem Siebboden besitzen die auf einer Unterstützungskonstruktion (1) austauschbar und selbstklemmend befestigten Siebelemente (4) eine Gummiplatte (11) als Verschleißschicht. Unterhalb der Gummiplatte (11) ist lediglich eine aus Kunststoffstegen bestehende und/oder eine in Kunststoff eingebettete Armierung (5) sowie Klemmelemente (7) angeordnet. Armierung (5) und Klemmelemente (7) bilden gemeinsam ein einteiliges Gitter, das mit der Gummiplatte unlösbar verbunden ist. Dadurch ist es ermöglicht, die aus dem Baukastenprinzip sich ergebenden Vorteile auch auf Siebböden mit Siebelementen zu übertragen, die im wesentlichen aus Gummi mit hoher Abriebswiderstandseigenschaft bestehen.In this sieve tray, the sieve elements (4), which are replaceable and self-clamping, are exchangeable and self-locking and have a rubber plate (11) as a wear layer. Below the rubber plate (11) there is only a reinforcement (5) consisting of plastic webs and / or embedded in plastic and clamping elements (7). Reinforcement (5) and clamping elements (7) together form a one-piece grid, which is permanently connected to the rubber plate. This makes it possible to transfer the advantages resulting from the modular principle to sieve trays with sieve elements which essentially consist of rubber with a high abrasion resistance property.

Description

Die Erfindung betrifft einen nach dem Baukastenprinzip aufgebauten Systemsiebboden mit einer Unterstützungskonstruktion, die Stützelemente aufweist,und mit darauf austauschbar angeordneten, armierten Siebelementen aus elastischem Werkstoff, die an ihrer Unterseite mit den Stützelementen zusammenwirkende Klemmelemente aus einem im Verarbeitungszustand gießfähigen Kunststoff, insbesondere einem Polyurethan, aufweisen.The invention relates to a modular sieve system with a support structure, which has support elements, and with interchangeably arranged, reinforced sieve elements made of elastic material, which have on their underside with the support elements cooperating clamping elements made of a castable plastic, in particular a polyurethane .

Ein Siebboden dieser Art dient ganz allgemein dazu, Siebgut, z.B. Gestein, Sand, Kies oder dergleichen zu entwässern und/oder zu klassieren. Ein solcher aus der DE-AS 28 49 838 bekannter Siebboden besteht aus einem Unterstützungsrahmen mit im Querschnitt c-förmigen Stützelementen und aus Siebelementen, die einstückig aus einem gummielastischen Kunststoff gefertigt sind. Die dazu verwendeten Kunststoffe, meist Polyurethane (PUR), mit hoher Abriebswiderstandseigenschaft liegen in ihrer Shore Härte über 80 A, in der Regel um 90 A. Die Verwendung von Siebböden mit Siebelementen aus diesen Kunststoffen für die Absiebung von Mineralien, besonders im Naß-Absiebverfahren, hat hervorragende Ergebnisse gebracht.A sieve tray of this type is generally used for sieve well, for example to drain and / or classify rock, sand, gravel or the like. Such a sieve tray known from DE-AS 28 49 838 consists of a support frame with support elements having a C-shaped cross section and of sieve elements which are made in one piece from a rubber-elastic plastic. The Shore hardness of the plastics used, mostly polyurethane (PUR), with high abrasion resistance properties is above 80 A, usually around 90 A. The use of sieve trays with sieve elements made of these plastics for the sieving of minerals, especially in the wet sieving process , has brought excellent results.

Einschränkungen mußten allerdings immer dann gemacht werden, wenn sehr hartes Gestein, beispielsweise Granit, Flint oder Quarz, grob gebrochen und trocken abgesiebt werden sollten. Offensichtlich reicht die Elastizität der abriebfesten aber vergleichsweise harten Kunststoffe nicht aus.However, restrictions always had to be made if very hard rock, for example granite, flint or quartz, was to be roughly broken and sieved dry. Obviously, the elasticity of the abrasion-resistant but comparatively hard plastics is not sufficient.

Der Erfindung liegt die Aufgabe zugrunde einen in der Fertigung, Montage und Vorratshaltung einfachen Siebboden mit hoher Siebleistung zu schaffen, dessen Siebelemente auch gegenüber sehr abrasivem Siebgut eine hohe Standfestigkeit besitzen.The invention has for its object to provide a simple in the manufacture, assembly and storage of sieve plate with high sieving performance, the sieve elements have a high stability even with very abrasive material.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß bei einem Siebboden der eingangs genannten Art die Siebelemente eine Verschleißschicht in Form einer gelochten Gummiplatte aufweisen und daß unterhalb der Gummiplatte lediglich die aus Kunststoffstegen bestehende und/oder in Kunststoff eingebettete Armierung und die Klemmelemente aus dem gleichen Kunststoff angeordnet und diese vollständig und unlösbar damit verbunden ist. Die Armierung ist dabei nicht in Form einer untergelegten Stützplatte, sondern als Stäbe, Profile, Drahtseile grobmaschiges Gitter oder dergleichen ausgebildet, die vorzugsweise vollständig in dem Kunststoff eingebettet ist. Die Gummiplatte ist im Bereich ihrer von Sieböffnungen freien Stegen, zwischen denen jeweils mindestens ein Feld von Sieböffnungen liegt, mit der eingebetteten Armierung verbunden. Bei streifenförmigen Siebelementen erstreckt sich die Armierung bevorzugt rechtwinklig.. d.h. quer zur Längserstreckung der Siebelemente. Dadurch ist es ermöglicht, die aus dem Baukastenprinzip sich ergebenden Vorteile auch auf Siebböden mit Siebelementen zu übertragen, die im wesentlichen aus Gummi mit hoher Abriebwiderstandeigenschaft bestehen. Für die Herstellung solcher Siebelemente sind keine komplizierten und teuren Vulkanisierformen und -einrichtungen erforderlich. Vielmehr können die bei der Herstellung von Siebelementen aus Kunststoff vorhandenen Formwerkzeuge zumindest teilweise mitverwendet werden. Als besonders geeignet für die Gummiplatte hat sich hochverschleißfester Spezial-Gummi mit einer Härte von etwa 70 Shore A erwiesen.This object is achieved in that the sieve elements in a sieve bottom of the type mentioned perforated a wear layer in the form of a perforated Have rubber plate and that only the reinforcement consisting of plastic webs and / or embedded in plastic and the clamping elements made of the same plastic are arranged below the rubber plate and this is completely and permanently connected to it. The reinforcement is not designed in the form of an underlying support plate, but as rods, profiles, wire ropes, coarse-meshed grids or the like, which is preferably completely embedded in the plastic. The rubber plate is connected to the embedded reinforcement in the area of its webs free from sieve openings, between which there is at least one field of sieve openings. In the case of strip-shaped sieve elements, the reinforcement preferably extends at a right angle. That is, transversely to the longitudinal extent of the sieve elements. This makes it possible to transfer the advantages resulting from the modular principle to sieve trays with sieve elements which essentially consist of rubber with a high abrasion resistance property. No complicated and expensive vulcanizing molds and devices are required to manufacture such screen elements. Rather, the molds available in the manufacture of plastic screen elements can be used at least in part. Highly wear-resistant special rubber with a hardness of around 70 Shore A has proven to be particularly suitable for the rubber sheet.

Aus siebtechnischen und fertigungstechnischen Gründen ist es günstig, wenn die in Kunststoff eingebettete Armierung und die aus dem gleichen Kunststoff bestehenden Klemmelemente ein im wesentlichen einteiliges Gitter bzw. einen einteiligen Rost bilden auf dem die Gummiplatte unmittelbar, vollständig und unlösbar angeordnet ist.For reasons of screen technology and manufacturing technology, it is favorable if the reinforcement embedded in plastic and that consist of the same plastic the clamping elements form a substantially one-piece grid or a one-piece grate on which the rubber plate is arranged directly, completely and permanently.

Als ganz besonders vorteilhaft hat es sich erwiesen, wenn die selbsttätig klemmenden Klemmelemente an mindestens zwei einander gegenüberliegenden Seitenrändern der Gummiplatte angeordnet sind und wenn die Klemmelemente jeweils einen parallel zum zugehörigen Seitenrand der Gummiplatte verlaufenden inneren Steg aufweisen, dem ein äußerer Fortsatz zugeordnet ist, wobei zwischen Steg und Innenseite des Fortsatzes eine Nut gebildet ist. Die Herstellung der Siebelemente kann noch wirtschaftlicher und einfacher erfolgen, wenn die Gummiplatte vor ihrer Verbindung mit den Klemmelementen und der gegebenenfalls vorhandenen Armierung vollständig vorgefertigt ist. Die Gummiplatte kann dazu z.B. von einer größeren Einheit, z.B. eine Platte oder eine Rolle, abgeschnitten und danach gelocht werden.It has proven to be particularly advantageous if the automatically clamping clamping elements are arranged on at least two mutually opposite side edges of the rubber plate and if the clamping elements each have an inner web running parallel to the associated side edge of the rubber plate, to which an outer extension is assigned, with between Web and inside of the extension a groove is formed. The production of the sieve elements can be made even more economically and easily if the rubber plate is completely prefabricated before it is connected to the clamping elements and the reinforcement which may be present. The rubber plate can e.g. from a larger unit, e.g. a plate or a roll, cut off and then punched.

Ein zwischen Gummiplatte und Klemmelemente eingebrachter Haftvermittler erhöht die Festigkeit der Verbindung zwischen den betreffenden Teilen.An adhesion promoter inserted between the rubber plate and the clamping elements increases the strength of the connection between the relevant parts.

Anhand der in der Zeichnung schematisch dargestellten Ausführungsbeispiele wird im folgenden die Erfindung näher erläutert.

  • Es zeigt: Figur 1 einen Schnitt eines erfin-a dungsgemäßen Siebbodens und
  • Figur 2 eine Unteransicht eines Siebelements desselben Siebbodens.
The invention is explained in more detail below on the basis of the exemplary embodiments shown schematically in the drawing.
  • 1 shows a section of a sieve tray according to the invention and FIG
  • Figure 2 is a bottom view of a screen element of the same screen bottom.

In Firgur 1 ist ein Schnitt eines erfindungsgemäßen Siebbodens gezeigt. Der Siebboden besitzt eine Unterstützungskonstruktion 1 mit einem Rahmen 2 und mit Stützelementen 3. Die im Querschnitt c-förmigen Stützelemente 3 können starr oder austauschbar mit dem Rahmen 2 verbunden sein. Die vorzugsweise streifenförmigen Siebelemente 4 des Siebbodens besitzen eine Armierung 5. An der Unterseite 6 der Siebelemente 4 sind Klemmelemente 7 bündig mit der Seitenkante der Siebelemente 4 angeordnet. Mit Hilfe der Klemmelemente 7 sind die Siebelemente auf den Stützelementen selbsttätig klemmend befestigt. Die selbsttätig klemmenden Klemmelemente 7 sind jeweils entlang der beiden einander gegenüberliegenden Seitenränder des betreffenden Siebelements 4 angeordnet. Sie weisen jeweils einen parallel zum zugehörigen Seitenrand verlaufenden inneren Steg 8 auf, dem ein äußerer Fortsatz 9 zugeordnet ist. Dadurch entsteht zwischen dem Steg und dem Fortsatz eine hinterschnittene Nut 10 innerhalb derer der zugehörige Schenkel des Stützelements festgehalten ist. Die Siebelemente 4 besitzen jeweils eine Gummiplatte 11 als Verschleißschicht. An der Unterseite 6 der Gummiplatte 11 befindet sich lediglich noch die in Kunststoff, insbesondere einem Polyurethan, eingebettete Armierung 5 und entlang der Seitenränder die Klemmelemente 7. Die Klemmelemente 7 und die Armierung 5 bilden ein einteiliges grobes Gitter oder einen einteiligen weitspaltigen Rost auf dem die Gummiplatte als Verschleißschicht ruht. Die Gummiplatte kann somit zonenweise frei schwingen, was sich günstig auf die Verstöpfungsfreiheit auswirkt.A section of a sieve tray according to the invention is shown in FIG. 1. The sieve bottom has a support structure 1 with a frame 2 and with support elements 3. The support elements 3, which are c-shaped in cross section, can be connected rigidly or interchangeably to the frame 2. The preferably strip-shaped sieve elements 4 of the sieve bottom have a reinforcement 5. On the underside 6 of the sieve elements 4, clamping elements 7 are arranged flush with the side edge of the sieve elements 4. With the help of the clamping elements 7, the sieve elements are automatically clamped on the support elements. The automatically clamping clamping elements 7 are each arranged along the two opposite side edges of the sieve element 4 in question. They each have an inner web 8 running parallel to the associated side edge, to which an outer extension 9 is assigned. This creates an undercut groove 10 between the web and the extension, within which the associated leg of the support element is held. The sieve elements 4 each have a rubber plate 11 as a wear layer. On the underside 6 of the rubber plate 11 there is only the reinforcement 5 embedded in plastic, in particular a polyurethane, and along the side tenränder the clamping elements 7. The clamping elements 7 and the reinforcement 5 form a one-piece coarse grid or a one-piece wide-column grate on which the rubber plate rests as a wear layer. The rubber plate can thus freely swing in zones, which has a positive effect on the freedom from clogging.

Die Gummiplatte wird bevorzugt vollständig vorgefertigt. Dazu kann sie von einer größeren Platte oder von einer Rolle abgeschnitten und mit den Sieblöchern, z.B. durch Stanzen, versehen werden. Danach wird die fertige Gummiplatte mit dem das einteilige grobe Gitter bzw. den weitspaltigen Rost bildenden Unterteil vollständig und unlösbar verbunden. Um die Haltbarkeit der Verbindung zu erhöhen wird zwischen der Gummiplatte und dem Gitter bzw. Rost ein Haftvermittler eingebracht.The rubber sheet is preferably completely prefabricated. To do this, it can be cut from a larger plate or from a roll and sealed with the sieve holes, e.g. by stamping. The finished rubber sheet is then completely and permanently connected to the lower part, which forms the one-piece coarse grid or the wide-gap grate. In order to increase the durability of the connection, an adhesion promoter is introduced between the rubber plate and the grid or grate.

In Figur 2 ist eine Unteransicht eines Siebelements 4 des in Figur 1 gezeigten Siebbodens dargestellt. Daraus ist besonders deutlich die Gitter- bzw. Rost-Struktur, gebildet aus der in Kunststoff eingebetteten Armierung 5 und den Klemmelementen, ersichtlich, die an der Unterseite der Gummiplatte vollständig und unlösbar befestigt ist. Die Gummiplatte wird somit nicht deckungsgleich, sondern nur linienförmig im Bereich ihrer von Sieböffnungen 11 freien Stegen 13 unterstützt. Die zwischen den Stegen 13 frei bleibenden Zonen der Gummiplatte können frei schwingen.FIG. 2 shows a bottom view of a sieve element 4 of the sieve bottom shown in FIG. 1. This clearly shows the lattice or rust structure, formed from the reinforcement 5 embedded in plastic and the clamping elements, which is completely and permanently attached to the underside of the rubber plate. The rubber plate is thus not congruent, but is only supported in a linear manner in the area of its webs 13 free of sieve openings 11. The zones of the rubber plate remaining between the webs 13 can swing freely.
