- the invention relates to a drum device - preferably screen drum device for the continuous heat treatment of web-like textile, nonwoven or paper with a z. B. gaseous, circulated in the device treatment agent having an internally under suction, frontal bottoms, for permeability z. B. perforated metal drum as a transport element for the web-shaped material - which is covered at its periphery with a permeable, tubular screen fabric, whose at least one circular end edge on a the outer diameter of the drum having concentric clamping ring on the associated end wall of the drum for constant compensation is elastically supported by the heat treatment by temperature variation mutually occurring changes in length of the screen fabric.
- a device of this type is known from DE-AS-1 729 487.
- the clamping ring consists of an angle profile ring, the outer diameter of which corresponds to the screen drum and on which the screen fabric is attached.
- spiral springs are directed to the opposite bottom wall of the screen drum, whereby the clamping ring pulls the screen fabric taut over the drum. Since the coil springs can transmit no radial force, the clamping ring must be held in position by rigid, attached to the bottom of the sieve drum adjusting bolts over which the clamping ring slides axially.
- this holder of the clamping ring is very susceptible to wear. Due to differential thermal expansion of the clamping ring relative to the sieve drum, the adjusting bolts are subjected to bending, which can not be compensated by radially aligned slots in the clamping ring. The result is wear in the end wall of the clamping ring until breakage of the adjusting bolts.
- the solution according to the FR-PS has regardless of a larger and thus detrimental in particular for large drums mass of the clamping ring friction of the clamping ring on the drum axis or on the outer diameter of the intake and result in the solution according to DE-AS therefore eliminated because the mesh in the constant expansion compensation during use is always pulled over the radially outer clamping edge of the clamping ring, which permanently destroys the tissue at this point.
- the invention has for its object to find an elastic Spannbefestist for a screened on a drum screen fabric, which also compensates the radially aligned forces by the mutually occurring thermal expansion forces on the clamping ring.
- the invention provides for solving the problem before, that the clamping ring is held via radially aligned, but axially effective spring elements centric to the outer diameter and radially equal to the outer diameter of the drum.
- the reason for this lies in the advantage of these spring elements that radially oriented spring elements can also absorb the forces arising in the radial direction, which have previously caused the destructive wear.
- This device only axial forces on the screen fabric are active, and only those that attack uniformly over the circumference on the clamping ring on the mesh. An uneven loading of the mesh over the circumference is eliminated, even during operation of the dryer. Wear elements are no longer available, because this type of spring elements are not subject to wear.
- the z. B. are mounted radially inwardly on the drum base.
- such spring elements which have a greater width, so are web-shaped.
- Particularly advantageous are those made of a sheet-like spring steel spring elements which are bent U-shaped and in which the spring tension is in the respective opening of the U-shaped spread.
- the closed end of the U-shaped spring is thus radially inwardly, while the two radially outwardly directed legs of the spring are axially - seen in the direction of the axis of the drum - spread.
- One leg is attached to the drum base and the other on the clamping ring, on which in turn the mesh fabric z. B. is held by a clamping ring.
- the sieve drum device essentially corresponds to the device according to DE-A-19 525 459.
- a conventional sieve drum device basically consists of an approximately rectangular housing, not shown here, which is subdivided into a treatment space and a fan space.
- the sieve drum 1 In the treatment room, the sieve drum 1 and concentrically to this in the fan room, a fan is rotatably mounted.
- the fan room can also be arranged in a separated from the screen drum housing, also not shown here, separate Ventüatorgephaseuse. In any case, the fan sets the interior of the drum 1 under induced draft.
- the sieve drum 1 consists of the two drum bases 2 and 3, which centrally have a hollow axis 4, 5, through which the interior of the drum 1 is set under induced draft.
- the stable trained drum bottoms 2, 3 have radially outwardly a simpler formed annular disc 6, which is firmly welded to the respective bottom 2, 3.
- Axial inward of the drum 1, these annular discs 6 carry in a respective Ring groove 7 the perforated drum shell 8, on which from Fig. 3 better apparent, U-shaped bent-up spacers 9 are attached to the externally wound up tubular screen fabric 10.
- the spacers 9 are located at a defined distance next to each other and with their radially inner surface directly on the drum basket 8.
- the sieve-like covering 10 in turn rests only on the radially outer edges of the U-shaped spacers 9, which ensures a uniform flow through the material resting on the sieve cloth 10.
- the screen fabric 10 is axially stretched and resiliently attached to the drum bases 2, 3 or to the annular discs 6.
- the spring elements 11 are made of a spring steel and bent in a U-shape and thus have two equal-length legs 11 'and 11 ", the obliquely apart in the untensioned state see the dashed lines, so the spring tension of the spring elements 11 is in the respective spread 16 of these two legs 11 'and 11 ".

Description
Die Erfindung bezieht sich auf eine Trommelvorrichtung - vorzugsweise Siebtrommelvorrichtung zum durchströmenden Wärmebehandeln von bahnförmigem Textilgut, Vlies oder Papier mit einem z. B. gasförmigen, in der Vorrichtung umgewälzten Behandlungsmittel mit einer innen unter Saugzug stehenden, stirnseitig Böden aufweisenden, zur Durchlässigkeit z. B. gelochten Blechtrommel als Transportelement für das bahnförmige Gut - , welche an ihrem Umfang mit einem durchlässigen, schlauchförmigen Siebgewebe bedeckt ist, dessen zumindest eine kreisrunde Stimkante an einem den Außendurchmesser der Trommel aufweisenden, konzentrisch angeordneten Spannring an der zugehörigen Stimwand der Trommel zum steten Ausgleich von beim Heißbehandeln durch Temperaturschwankung wechselseitig auftretenden Längenänderungen des Siebgewebes elastisch abgestützt ist.The invention relates to a drum device - preferably screen drum device for the continuous heat treatment of web-like textile, nonwoven or paper with a z. B. gaseous, circulated in the device treatment agent having an internally under suction, frontal bottoms, for permeability z. B. perforated metal drum as a transport element for the web-shaped material - which is covered at its periphery with a permeable, tubular screen fabric, whose at least one circular end edge on a the outer diameter of the drum having concentric clamping ring on the associated end wall of the drum for constant compensation is elastically supported by the heat treatment by temperature variation mutually occurring changes in length of the screen fabric.
Eine Vorrichtung dieser Art ist durch die DE-AS-1 729 487 bekannt. Der Spannring besteht aus einem Winkelprofilring, dessen Außendurchmesser dem der Siebtrommel entspricht und auf dem das Siebgewebe befestigt ist. Gegen die senkrecht dazu ausgerichtete Stirnwandung des Spannrings sind an der gegenüberliegenden Bodenwand der Siebtrommel abgestützte Spiralfedern gerichtet, womit der Spannring das Siebgewebe über die Trommel straff zieht. Da die Spiralfedern radial keine Kraft übertragen können, muss der Spannring durch starre, am Siebtrommelboden befestigte Justierbolzen, über die der Spannring axial gleitet, in Position gehalten werden.A device of this type is known from DE-AS-1 729 487. The clamping ring consists of an angle profile ring, the outer diameter of which corresponds to the screen drum and on which the screen fabric is attached. Against the perpendicularly oriented end wall of the clamping ring supported spiral springs are directed to the opposite bottom wall of the screen drum, whereby the clamping ring pulls the screen fabric taut over the drum. Since the coil springs can transmit no radial force, the clamping ring must be held in position by rigid, attached to the bottom of the sieve drum adjusting bolts over which the clamping ring slides axially.
In der Praxis hat sich gezeigt, dass diese Halterung des Spannrings sehr verschleißanfällig ist. Durch unterschiedliche Wärmeausdehnung des Spannrings gegenüber der Siebtrommel werden die Justierbolzen auf Biegung beansprucht, was durch radial ausgerichtete Langlöcher im Spannring nicht ausgeglichen werden kann. Die Folge ist ein Verschleiß in der Stirnwandung des Spannrings bis zum Bruch der Justierbolzen.In practice, it has been shown that this holder of the clamping ring is very susceptible to wear. Due to differential thermal expansion of the clamping ring relative to the sieve drum, the adjusting bolts are subjected to bending, which can not be compensated by radially aligned slots in the clamping ring. The result is wear in the end wall of the clamping ring until breakage of the adjusting bolts.
Man könnte nun auf die Idee kommen, entsprechend der FR-PS 1 430 928 den Spannring auf der Achse der Trommel abzustützen oder wie bei der DE-AS 1 297 978 das Siebgewebe über den Spannring radial nach innen zu ziehen und dort über radial ausgerichtete Spiralfedern an einem Ring zu befestigen, der seinerseits auf der Achse der Trommel gelagert ist. Die Lösung nach der FR-PS hat unabhängig von einer größeren und damit insbesondere bei Großtrommeln nachteiligen Masse des Spannrings eine Reibung des Spannrings auf der Trommelachse oder am Außendurchmesser des Ansaugstutzens zur Folge und die Lösung nach der DE-AS entfällt deshalb, weil das Siebgewebe bei dem ständigen Dehnungsausgleich während der Benutzung immer über die radial außen liegende Spannkante des Spannrings gezogen wird, was auf Dauer das Gewebe an dieser Stelle zerstört.One could now come up with the idea according to FR-
Der Erfindung liegt die Aufgabe zugrunde eine elastische Spannbefestigung für ein auf eine Trommel aufgezogenes Siebgewebe zu finden, die auch die radial ausgerichteten Kräfte durch die wechselseitig auftretenden Wärmedehnungskräfte am Spannring kompensiert.The invention has for its object to find an elastic Spannbefestigung for a screened on a drum screen fabric, which also compensates the radially aligned forces by the mutually occurring thermal expansion forces on the clamping ring.
Ausgehend von der Vorrichtung anfangs genannter Art, sieht die Erfindung zur Lösung der gestellten Aufgabe vor, dass der Spannring über radial ausgerichtete, aber axial wirksame Federelemente zentrisch zum Außendurchmesser und radial in Höhe des Außendurchmessers der Trommel gehalten ist. Dies heißt, dass die Federelemente das Siebgewebe nicht über die Kante des Spannrings ziehen und dennoch radial ausgerichtet sind. Der Grund dafür liegt in dem Vorteil dieser Federelemente, dass radial ausgerichtete Federelemente eben auch die in radialer Richtung entstehenden Kräfte aufnehmen können, die bisher den zerstörerischen Verschleiß bewirkt haben. Mit dieser Vorrichtung werden nur noch axiale Kräfte an dem Siebgewebe aktiv, und zwar nur solche, die gleichmäßig über den Umfang über den Spannring an dem Siebgewebe angreifen. Eine ungleichmäßige Belastung des Siebgewebes über den Umfang entfällt, und zwar auch während des Betriebes des Trockners. Verschleißelemente sind nicht mehr vorhanden, denn diese Art von Federelemente unterliegen keinem Verschleiß.Starting from the device initially mentioned type, the invention provides for solving the problem before, that the clamping ring is held via radially aligned, but axially effective spring elements centric to the outer diameter and radially equal to the outer diameter of the drum. This means that the spring elements do not pull the screen fabric over the edge of the clamping ring and are nevertheless aligned radially. The reason for this lies in the advantage of these spring elements that radially oriented spring elements can also absorb the forces arising in the radial direction, which have previously caused the destructive wear. With this device, only axial forces on the screen fabric are active, and only those that attack uniformly over the circumference on the clamping ring on the mesh. An uneven loading of the mesh over the circumference is eliminated, even during operation of the dryer. Wear elements are no longer available, because this type of spring elements are not subject to wear.
Als Federelemente dieser Art kommen Blattfedern infrage, die z. B. radial einwärts am Trommelboden zu befestigen sind. Vorteilhaft sind solche Federelemente, die eine größere Breite aufweisen, also stegförmig ausgebildet sind. Damit werden die radial wirksamen Kräfte über die radial gerichteten Stege, wie bei Speichen am Rad von dem Boden der Trommel aufgenommen. Damit ist der Spannring, obgleich axial beweglich auch radial abgestützt, und zwar ohne dass eine irgendwie geartete Reibung und damit Verschleiß entstehen kann.As spring elements of this type come leaf springs in question, the z. B. are mounted radially inwardly on the drum base. Advantageously, such spring elements, which have a greater width, so are web-shaped. Thus, the radially effective forces on the radially directed webs, as recorded at spokes on the wheel of the bottom of the drum. This is the clamping ring, although axially movable also supported radially, and without any kind of friction and thus wear can occur.
Besonders vorteilhaft sind solche aus einem flächenförmigen Federstahl gefertigten Federelemente, die U-förmig aufgebogen sind und bei denen die Federspannung in der jeweiligen Öffnung der U-förmigen Spreizung liegt. Das geschlossene Ende der U-förmigen Feder liegt damit radial einwärts, während die beiden radial nach außen gerichteten Schenkel der Feder axial - in Richtung der Achse der Trommel gesehen - gespreizt sind. Der eine Schenkel ist an dem Trommelboden befestigt und der andere an dem Spannring, an dem wiederum das Siebgewebe z. B. über einen Klemmring gehalten ist.Particularly advantageous are those made of a sheet-like spring steel spring elements which are bent U-shaped and in which the spring tension is in the respective opening of the U-shaped spread. The closed end of the U-shaped spring is thus radially inwardly, while the two radially outwardly directed legs of the spring are axially - seen in the direction of the axis of the drum - spread. One leg is attached to the drum base and the other on the clamping ring, on which in turn the mesh fabric z. B. is held by a clamping ring.

Die Siebtrommelvorrichtung entspricht im wesentlichen der Vorrichtung nach der DE-A-19 525 459. Eine übliche Siebtrommelvorrichtung besteht grundsätzlich aus einem hier nicht dargestellten etwa rechteckigen Gehäuse, das in einen Behandlungsraum und einen Ventilatorraum unterteilt ist. Im Behandlungsraum ist die Siebtrommel 1 und konzentrisch zu dieser im Ventilatorraum ein Ventilator drehbar gelagert. Selbstverständlich kann der Ventilatorraum auch in einem von dem Siebtrommelgehäuse abgetrennten, hier ebenfalls nicht dargestellten, gesonderten Ventüatorgehäuse angeordnet sein. Jedenfalls setzt der Ventilator das Innere der Trommel 1 unter Saugzug.The sieve drum device essentially corresponds to the device according to DE-A-19 525 459. A conventional sieve drum device basically consists of an approximately rectangular housing, not shown here, which is subdivided into a treatment space and a fan space. In the treatment room, the
Die Siebtrommel 1 besteht aus den beiden Trommelböden 2 und 3, die zentrisch eine hohle Achse 4, 5 aufweisen, durch die das Innere der Trommel 1 unter Saugzug gesetzt ist. Die stabil ausgebildeten Trommelböden 2, 3 weisen radial außen eine einfacher ausgebildete Ringscheibe 6 auf, die mit dem jeweiligen Boden 2, 3 fest verschweißt ist. Axial einwärts der Trommel 1 tragen diese Ringscheiben 6 in einer jeweiligen Ringnut 7 den gelochten Trommelmantel 8, auf dem die aus Fig. 3 besser ersichtlichen, U-förmig aufgebogenen Abstandshalter 9 für das außerhalb aufgezogene schlauchförmige Siebgewebe 10 befestigt sind. Die Abstandshalter 9 liegen mit einem definierten Abstand nebeneinander und mit ihrer radial innen liegenden Fläche unmittelbar auf dem Siebtrommelmantel 8 auf. Der siebförmige Belag 10 seinerseits liegt nur auf den radial außen angeordneten Kanten der U-förmigen Abstandshalter 9 auf, was eine gleichmäßige Durchströmung des auf dem Siebgewebe 10 aufliegenden Gutes gewährleistet.The
Das Siebgewebe 10 ist an den Trommelböden 2, 3 bzw. an den Ringscheiben 6 axial gespannt und elastisch zu befestigen. Dazu dienen U-förmig gebogene, eine größere aus Fig. 3 ersichtliche Breite aufweisende Federelemente 11. Die Federelemente 11 sind aus einem Federstahl gefertigt und U-förmig gebogen und haben damit zwei gleichlange Schenkel 11' und 11", die in ungespanntem Zustand schräg auseinander gerichtet sind, siehe dazu die gestrichelten Linien. Die Federspannung der Federelemente 11 liegt also in der jeweiligen Spreizung 16 dieser beiden Schenkel 11' und 11".The
Zur gespannten Befestigung des Siebgewebeschlauches 10 sind die Federelemente 11 mit ihrer geschlossenen Seite radial zur Trommelachse ausgerichtet. Der eine radial nach außen gerichtete Schenkel 11" des Federelementes 11 ist über Schrauben 12 an der Ringscheibe 6 und damit an dem Trommelboden 2, 3 befestigt, während der andere Schenkel 11' an dem Spannring 13 für das Siebgewebe 10 über entsprechende Schrauben 14 befestigt ist. Die Befestigung der Federelemente 11 an dem Trommelboden und an dem Spannring 13 ist auf gleicher radialen Höhe vorgesehen. Axial außerhalb des Spannrings ist dann noch der Klemmring 15, der auch aus Ringsegmenten bestehen kann, notwendig, um in dem Spalt zwischen Klemmring und Spannring den Rand des Siebgewebes 10 zu klemmen, zu halten.For tensioned attachment of the Siebgewebelauches 10, the
Zum Spannen des Siebgewebes 10 sind mit einer nicht dargestellten Hilfsvorrichtung die Federelemente um den ganzen Federweg 16 zusammenzudrücken, der Klemmring 15 mit dem Spannring 13 und zwischen diesen das Siebgewebe 10 mittels Schrauben oder dergl. fest zu verbinden. Nach Lösen der Hilfsvorrichtung wird das Siebgewebe gespannt und liegt dann fest auf den Stegen der U-förmigen Abstandshalter 9 auf. Bei im Betrieb auftretenden wärmebedingten Spannungszustandsänderungen gleichen diese die Federelemente in axialer und auch in radialer Richtung aus.For tensioning the
