Die Erfindung betrifft ein Siebtrommelgerippe, eine Siebtrommel sowie ein Verfahren zur Montage eines Siebtrommelgerippes gemäß dem Anspruch 1 bzw. 5 bzw. 8.The invention relates to a screen drum skeleton, a screen drum and a method for assembling a screen drum skeleton according to claims 1, 5 and 8, respectively.

Aus der US 2007/0074998 A1 ist ein Siebtrommelgerät mit einer Siebtrommel bekannt, welche in zylindrische Trommelabschnitte bzw. Siebringe zerlegbar ist.From the US 2007/0074998 A1 is a Siebtrommelgerät known with a sieve drum, which can be disassembled into cylindrical drum sections or Siebringe.

Es ist Aufgabe der Erfindung, ein Siebtrommelgerippe bzw. eine Siebtrommel vorzuschlagen, welche für einen Transport und insbesondere für einen Straßentransport optimal geeignet ist und trotzdem eine hohe Stabilität und Maßhaltigkeit aufweist. Weiterhin ist es Aufgabe der Erfindung, ein Verfahren zur Montage eines Siebtrommelgerippes vorzuschlagen, durch welches sich ein für den Transport, insbesondere Straßentransport optimal geeignetes Siebtrommelgerippe mit minimalem Aufwand zusammenbauen lässt.It is an object of the invention to provide a screen drum or a screen drum, which is optimally suitable for transport and in particular for a road transport and still has a high stability and dimensional stability. Furthermore, it is an object of the invention to provide a method for assembling a Siebtrommelgerippes, by which can be assembled with minimal effort for the transport, especially road transport optimally suitable Siebtrommelgerippe.

Diese Aufgabe wird durch die Merkmale des Anspruchs 1 bzw. 5 bzw. 8 gelöst. In den Unteransprüchen sind vorteilhafte und zweckmäßige Weiterbildungen angegeben.This object is solved by the features of claim 1 or 5 and 8, respectively. In the dependent claims advantageous and expedient developments are given.

Das erfindungsgemäße Siebtrommelgerippe umfasst einen linken Außenring, einen rechten Außenring, eine Vielzahl von Längsrippen und eine Vielzahl von Querrippen, wobei sich die Längsrippen ununterbrochen von dem linken Außenring zu dem rechten Außenring erstrecken, wobei die Längsrippen als U-Profile ausgebildet sind, wobei die Längsrippen mit den Außenringen durch Verbindungsmittel verbunden sind und wobei jede Querrippe mit ihren beiden Enden jeweils zwei benachbarte Längsrippen verbindet und mit diesen durch Verbindungsmittel verbunden ist. Ein derartiges Siebtrommelgerippe lässt sich in eine Vielzahl von Bauteilen mit geringem Transportvolumen zerlegen und ist somit für einen Transport, insbesondere einen Straßentransport oder einen Containertransport auf dem Land-, See- oder Luftweg optimal geeignet. Die Außenringe bilden flache Scheiben, welche ggf. hochkant und stehend transportiert werden können. Die Längsrippen bilden lange Stäbe, welche in Fahrtrichtung liegend transportiert werden können und die Querrippen bilden kurze Bogenabschnitte, welche ebenfalls in Fahrtrichtung liegend transportiert werden können.The screen drum frame according to the invention comprises a left outer ring, a right outer ring, a plurality of longitudinal ribs and a plurality of transverse ribs, wherein the longitudinal ribs extend continuously from the left outer ring to the right outer ring, wherein the longitudinal ribs are formed as U-profiles, wherein the longitudinal ribs with the Outer rings are connected by connecting means and wherein each transverse rib connects at its two ends in each case two adjacent longitudinal ribs and is connected thereto by connecting means. Such a screen drum can be broken down into a plurality of components with low transport volume and is thus optimally suited for transport, in particular road transport or container transport by land, sea or air. The outer rings form flat slices, which can be transported upright and standing if necessary. The longitudinal ribs form long rods, which can be transported lying in the direction of travel and the transverse ribs form short arc sections, which can also be transported lying in the direction of travel.

Es ist weiterhin vorgesehen, die als U-Profile ausgebildeten Längsrippen mit Querstegen auszustatten, wobei die Querstege senkrecht zu den Schenkeln der U-Profile verlaufen und mit den Schenkeln und insbesondere auch mit einem Mittelsteg der U-Profile verschweißt sind und wobei die Schenkel der U-Profile im Bereich ihrer Querstege Bohrungen zur Befestigung der Querrippen aufweisen. Durch derartige Querstege wird die Torsionssteifigkeit der Längsrippen erhöht. Weiterhin ermöglichen die Querstege, welche fluchtend zu den Querrippen ausgerichtet sind, eine verbesserte Kraftübertragung zwischen zwei benachbarten Querrippen.It is also provided to equip the U-shaped longitudinal ribs with transverse webs, wherein the transverse webs are perpendicular to the legs of the U-profiles and welded to the legs and in particular with a central web of the U-profiles and wherein the legs of the U -Profile in the region of their transverse webs have holes for attachment of the transverse ribs. Such transverse webs increase the torsional rigidity of the longitudinal ribs. Furthermore, the transverse webs, which are aligned in alignment with the transverse ribs, allow an improved force transmission between two adjacent transverse ribs.

Es ist auch vorgesehen, die Querrippen als T-Profile auszubilden und an beiden Enden mit einer senkrecht zu ihrem Mittelsteg angeordneten Flanschplatte auszustatten, wobei die Flanschplatte mit dem Mittelsteg und mit Schenkeln der T-Profile verschweißt ist und wobei die Flanschplatte Bohrungen zur Befestigung der Querrippen an den Schenkeln der Längsrippen umfasst. Derartige Querrippen weisen mit den Flanschplatten Anlageflächen auf, mit welchen diese im montierten Zustand flächig an den Längsrippen anliegen, so dass die Längsrippen und die Querrippen in einem definierten Winkel miteinander verbunden werden und sich gegenseitig gegen eine Fehlausrichtung stabilisieren.It is also envisaged to form the transverse ribs as T-profiles and to equip at both ends with a flange plate arranged perpendicular to its central web, wherein the flange plate is welded to the central web and with legs of the T-profiles and wherein the flange plate bores for fixing the transverse ribs on the thighs of the longitudinal ribs. Such transverse ribs have bearing surfaces with the flange plates with which they rest flat against the longitudinal ribs in the mounted state, so that the longitudinal ribs and the transverse ribs are connected to one another at a defined angle and stabilize each other against misalignment.

Weiterhin ist es vorgesehen, die Querrippen als gebogene T-Profile auszubilden oder die Querrippen als aus flächigen Zuschnitten geschweißte T-Profile auszubilden, wobei eine Biegelinie bzw. eine gedachte Biegelinie jeweils im Übergangsbereich eines Mittelstegs zu Schenkeln liegt. Derartige Biegeteile lassen sich kostengünstig aus normierten Halbzeugen herstellen bzw. mit derartigen Schweißteilen lassen sich höchste Anforderungen an die Maßhaltigkeit erfüllen.Furthermore, it is provided to form the transverse ribs as curved T-profiles or to form the transverse ribs as T-profiles welded from flat blanks, wherein a bending line or an imaginary bending line lies in each case in the transition region of a central web to legs. Such bent parts can be inexpensively manufactured from normalized semi-finished or with such welds can meet the highest dimensional requirements.

Die erfindungsgemäße Siebtrommel umfasst ein Siebtrommelgerippe nach wenigstens einem der vorhergehenden Ansprüche 1 bis 4 und eine Vielzahl von einen Trommelmantel bildenden Siebblechen, wobei die Siebbleche jeweils in durch Längsrippen und Querrippen gebildeten Feldern angeordnet sind und mit den Längsrippen und Querrippen verschraubt sind und wobei die an die Außenringe grenzenden Siebbleche zusätzlich mit den Außenringen verschraubt sind. Eine derartige Siebtrommel ist durch ihren modularen Aufbau aus Einzelbauteilen mit geringen Volumen optimal für einen Transport geeignet und bildet im montierten Zustand weiterhin eine stabile und maßhaltige Siebtrommel, da alle Einzelteile durch Verschraubungen miteinander verbunden sind.The screen drum according to the invention comprises a screen drum frame according to at least one of the preceding claims 1 to 4 and a plurality of a drum shell forming screen plates, wherein the screen plates are arranged in each case in longitudinal ribs and transverse ribs formed fields and are screwed to the longitudinal ribs and transverse ribs and wherein the attached to the Outer rings adjacent screen plates are additionally bolted to the outer rings.

Siebblechen mit einer ersten Sieblänge und welche aus Feldern mit der zweiten Feldfläche bzw. Siebblechen mit einer zweiten Sieblänge gebildet sind, eine Gesamtlänge der Siebtrommel trotz der Verwendung nur zweier unterschiedlicher Feldflächen in kleinen Schritten zu variieren. Hierbei ist jeder Siebring der Siebtrommel aus Siebblechen gleicher Länge gebildet ist und wobei die zweite Länge wenigstens 10% größer ist als die erste Länge.It is likewise provided that a screen drum skeleton formed between the longitudinal ribs distributed uniformly around the circumference, the transverse ribs or rib rings and the outer rings between longitudinal ribs and its transverse ribs comprises exclusively fields with a first field surface and with a second field surface, the second field surface being larger in particular as at least 10% larger than the first field area.

Hierbei sind die Längsrippen 18 als U-Profile U18 ausgebildet und mit den Außenringen 16, 17 durch die Verbindungsmittel 20 verbunden, wobei die Verbindungsmittel 20 als Verschraubungen ausgeführt sind. Das in der Figur 3 gezeigte unvollständige Siebtrommelgerippe 10 wird zunächst noch um weitere Längsrippen 18 ergänzt, welche jeweils zwischen den dargestellten Längsrippen 18 eingebaut werden, um dann durch den Einbau der Querrippen 19 (siehe Figur 4) weiter versteift zu werden. Hierbei verbindet jede Querrippe 19 mit ihren beiden Enden 21, 22 jeweils zwei unmittelbar benachbarte Längsrippen 18, wobei dies wieder mit Hilfe der Verbindungsmittel 20 erfolgt. Zwischen den Längsrippen 18 und den Querrippen 19 sind eine Vielzahl von Feldern 23 gebildet, in welche zur Bildung der vollständigen Siebtrommel 2 hier nicht dargestellte Siebbleche eingesetzt werden, wobei diese ebenfalls durch Verbindungsmittel mit den Längsrippen 18, den Querrippen 19 und sofern diese an die Außenringen 16, 17 angrenzen, auch mit den Außenringen 16, 17 durch Befestigungsmittel verbunden werden. FIG. 4 shows the screen drum frame 10 in its entirety. Essentially, the screen drum frame 10 comprises a left outer ring 16, a right outer ring 17, seven longitudinal ribs 18, a plurality of transverse ribs 19 and a plurality of connecting means 20 for connecting said individual components. Like from the FIG. 3 It can be seen that the screen drum 10 shows only incomplete, the longitudinal ribs 18 extend continuously from the left outer ring 16 to the right outer ring 17. Here, the longitudinal ribs 18 are formed as U-profiles U18 and connected to the outer rings 16, 17 by the connecting means 20 , wherein the connecting means 20 are designed as screw connections. That in the FIG. 3 shown incomplete screen drum frame 10 is initially supplemented by further longitudinal ribs 18, which are respectively installed between the illustrated longitudinal ribs 18, to then by the installation of the transverse ribs 19 (see FIG. 4 ) to be further stiffened. In this case, each transverse rib 19 connects with its two ends 21, 22 in each case two directly adjacent longitudinal ribs 18, this again taking place with the aid of the connecting means 20. Between the longitudinal ribs 18 and the transverse ribs 19, a plurality of fields 23 are formed, in which to form the complete screening drum 2 screen plates not shown here are used, which also by connecting means with the longitudinal ribs 18, the Transverse ribs 19 and, if they are adjacent to the outer rings 16, 17, are also connected to the outer rings 16, 17 by fastening means.

In der Figur 5 ist die vollständige Siebtrommel 2 nochmals dargestellt und es ist erkennbar, dass alle Felder 23 durch Siebbleche 11 ausgefüllt sind, wobei jedes Siebblech 11 auch eine weitere Versteifung des Siebtrommelgerippes 10 bildet.In the FIG. 5 is the complete screen drum 2 shown again and it can be seen that all fields 23 are filled through screen plates 11, wherein each screen plate 11 also forms a further stiffening of the Siebtrommelgerippes 10.

Wie in der Figur 6, welche ein Detail der Figur 4 zeigt, dargestellt ist, umfassen die als U-Profile U18 ausgebildeten Längsrippen 18 Querstege 24. Die Querstege 24 sind hierbei senkrecht zu Schenkeln S18a, S18b des U-Profils U18 ausgerichtet und mit den Schenkeln S18a, S18b und einem Mittelsteg M18 verschweißt. Die Querstege 24 sind in den U-Profilen U18 dort angeordnet, wo Querrippen 19 auf das U-Profil 18 treffen. Entsprechend weisen die Schenkel S18a, S18b des U-Profils U18 im Bereich ihrer Querstege 24 Bohrungen 25 zur Befestigung der Querrippen 19 auf. Die Querrippen 19 sind als T-Profile T19 ausgebildet und umfassen an ihren beiden Enden 21, 22 jeweils eine senkrecht zu ihrem Mittelsteg M19 angeordnete Flanschplatte 26, 27. Hierbei ist die Flanschplatte 26 bzw. 27 mit dem Mittelsteg M19 und mit Schenkeln S19a, S19b der T-Profile T19 verschweißt. Die beiden Flanschplatte 26, 27 umfassen jeweils Bohrungen 28, welche auf die in den Längsrippen 18 ausgeführten Bohrungen 25 ausgerichtet sind. Somit können die Querrippen 19 mit ihren Flanschplatten 26, 27 an den Schenkeln S18a, S18b der Längsrippen 18 durch die Befestigungsmittel 20 fixiert werden. Hierbei umfasst jedes Befestigungsmittel 20 jeweils eine Schraube 20a, eine Mutter 20b und einen Sicherungsring 20c. Durch die Querstege 24 erfolgt jeweils eine Fortführung der Mittelstege M19 der Querrippen 19 über die Längsrippen 18 hinweg, so dass eine Struktur entsteht, welche einer ringförmigen Ausführung der Querrippen bezüglich der Belastbarkeit und Steifigkeit gleichwertig ist. Die dargestellten T-Profile T19 sind als aus flächigen Zuschnitten geschweißte T-Profile ausgebildet, bei welchen eine gedachte Biegelinie BL in einem Übergangsbereich des Mittelstegs M19 zu den Schenkeln S19a, S19b liegt.Like in the FIG. 6 which is a detail of FIG. 4 The transverse webs 24 are in this case aligned perpendicular to legs S18a, S18b of the U-profile U18 and welded to the legs S18a, S18b and a central web M18. The transverse webs 24 are arranged in the U-profiles U18 where transverse ribs 19 strike the U-profile 18. Accordingly, the legs S18a, S18b of the U-profile U18 in the region of their transverse webs 24 holes 25 for fixing the transverse ribs 19. The transverse ribs 19 are formed as T-profiles T19 and comprise at their two ends 21, 22 each one perpendicular to its central web M19 arranged flange plate 26, 27. Here, the flange plate 26 and 27 with the central web M19 and legs S19a, S19b the T-profile T19 welded. The two flange plates 26, 27 each comprise bores 28, which are aligned with the bores 25 formed in the longitudinal ribs 18. Thus, the transverse ribs 19 can be fixed with their flange plates 26, 27 on the legs S18a, S18b of the longitudinal ribs 18 by the fastening means 20. Here, each fastening means 20 each comprise a screw 20a, a nut 20b and a locking ring 20c. By the transverse webs 24 is carried out in each case a continuation of the central webs M19 of the transverse ribs 19 on the longitudinal ribs 18 away, so that a structure is created, which is equivalent to an annular design of the transverse ribs with respect to the load capacity and rigidity. The illustrated T-profiles T19 are designed as T-profiles welded from flat blanks, in which an imaginary bending line BL in a transition region of the central web M19 to the legs S19a, S19b is located.

Figur 7 zeigt als Detaildarstellung zu der Figur 3 in vergrößerter Ansicht wie die Längsrippen 18 mit dem rechten Außenring 17 verbunden sind. An Enden 29, 30 (siehe auch Figur 3) umfasst jede Längsrippe 18 jeweils einen ihr U-Profil U18 abschließenden Flanschkopf 31, 32, welcher eine Flanschplatte 33 und Rippen 34a - 34d umfasst, mit welcher bzw. mit welchen dieser an die Schenkel S18a, S18b und an den Mittelsteg M18 des U-Profils U18 angebunden ist. Hierdurch ist jeweils eine knickstabile Verbindung zwischen den Längsrippen 18 und den Außenringen 16, 17 geschaffen. FIG. 7 shows as a detail to the FIG. 3 in an enlarged view of how the longitudinal ribs 18 are connected to the right outer ring 17. At ends 29, 30 (see also FIG. 3 ) each longitudinal rib 18 comprises a respective U-profile U18 final flange head 31, 32, which comprises a flange plate 33 and ribs 34a - 34d, with which or with which this to the legs S18a, S18b and the central web M18 of the U- Profiles U18 is connected. As a result, a kink-resistant connection between the longitudinal ribs 18 and the outer rings 16, 17 is created in each case.

In der Figur 8 ist schließlich eines der als Grobsieb 13 ausgebildeten Siebbleche 11 in einer vergrößerten Darstellung der Figur 2 gezeigt. In der Darstellung ist erkennbar, dass das Siebblech 11, welches an den linken Außenring 16 angrenzt, mit diesem, den anliegenden Längsrippen 18 und der anliegenden Querrippe 19 verschraubt ist und somit die Längsrippen 18 und die Querrippe 19 in ihrer Ausrichtung auf den Außenring 16 stabilisiert.In the FIG. 8 is finally one of the screen formed as a coarse screen 13 11 in an enlarged view of FIG. 2 shown. In the illustration, it can be seen that the screen plate 11, which adjoins the left outer ring 16, is screwed to this, the adjoining longitudinal ribs 18 and the adjacent transverse rib 19 and thus stabilizes the longitudinal ribs 18 and the transverse rib 19 in alignment with the outer ring 16 ,

Aus der Figur 2 ist ersichtlich wie eine erste Gruppe A von Rippenringen R19a, R19b und R19c, welche durch die Querrippen 19 gebildet ist, in Längserstreckung des Siebtrommelgerippes 10 jeweils in gleichen, ersten Abständen a voneinander beabstandet ist und dass eine zweite Gruppe B von Rippenringen R19c und R19d, welche durch die Querrippen 19 gebildet ist, in Längserstreckung des Siebtrommelgerippes 10 jeweils in gleichen, zweiten Abständen b voneinander beabstandet ist, wobei die zu den beiden Außenringen 16, 17 benachbarten Rippenringe R19a und R19d zu diesen den ersten oder den zweiten Abstand a, b aufweisen. Hierbei ist der zweite Abstand b größer als der erste Abstand a, wobei der erste Abstand etwa 1,33 m und der zweite Abstand etwa 1,5 m beträgt, so dass die Gesamtsieblänge etwa 7 m beträgt.From the FIG. 2 is seen as a first group A of rib rings R19a, R19b and R19c, which is formed by the transverse ribs 19, in the longitudinal extension of the Siebtrommelgerippes 10 spaced at equal, first distances a from each other and that a second group B of rib rings R19c and R19d, which is formed by the transverse ribs 19, in the longitudinal extension of the Siebtrommelgerippes 10 each at equal, second distances b is spaced from each other, wherein the two outer rings 16, 17 adjacent rib rings R19a and R19d to these the first or the second distance a, b , Here, the second distance b is greater than the first distance a, wherein the first distance is about 1.33 m and the second distance is about 1.5 m, so that the total screen length is about 7 m.
