Description

Speichertanksystem mit Absperrvorrichtung Storage tank system with shut-off device
Die Erfindung betrifft eine Absperrvorrichtung für einen Speichertank, insbesondere einen Drucklufttank nach dem Oberbegriff des Anspruchs 1 sowie ein Speichertanksystem mit mehreren derartigen Absperrvorrichtungen, die an einem Speichertank festgelegt sind und diesen zumindest teilweise durchsetzen.The invention relates to a shut-off device for a storage tank, in particular a compressed air tank according to the preamble of claim 1 and a storage tank system with a plurality of such shut-off devices which are fixed to a storage tank and enforce this at least partially.
Derartige Systeme mit einem Drucklufttank sind beispielsweise aus der DE 1 407 922 A1 bekannt und dienen dabei der pneumatischen Abreinigung der Filter von Luftfilteranlagen mittels von der Reinigungskammer aus in zeitlichen Abständen axial gegen die Mündung der Filterorgane gerichteter Druckluftstöße. Diese werden turnusmäßig von Schaltaggregaten ausgelöst, die mit Membrandeckeln der Absperrvorrichtungen verbunden sind und aus dem Drucklufttank bei Betätigung Druckluftstöße durch Einsatzrohre zu angeschlossenen Blasdüsen hin lenken. Bei dem in der DE 1 407 922 gezeigten System gehen die Einsatzrohre in die Blasdüsen über und erstrecken sind aus der Unterseite des Drucklufttanks hinaus. Zur Funktionsfähigkeit des Systems müssen sie an der Unterseite mit dem Drucklufttank beispielsweise verschweißt sein.Such systems with a compressed air tank are known for example from DE 1 407 922 A1 and serve the pneumatic cleaning of the filter of air filter systems by means of the cleaning chamber at intervals axially against the mouth of the filter organs directed compressed air surges. These are regularly triggered by switching units, which are connected to membrane covers of the shut-off devices and direct compressed air surges from the compressed air tank through feed pipes to connected tuyeres. In the system shown in DE 1 407 922, the feed pipes extend into the blowing nozzles and extend out of the underside of the compressed-air tank. For the functionality of the system, they must be welded at the bottom with the compressed air tank, for example.
In der Praxis sind andere Systeme bekannt, bei denen sich das Einsatzrohr ebenfalls untenseitig aus dem Drucklufttank heraus erstreckt und ein Außengewinde aufweist, das mit einem ein Innengewinde aufweisenden Anschlussstück unterhalb des Drucklufttanks befestigend verschraubt ist. An der Oberseite wird die Verbindung über einen Rohrhalter hergestellt, der durch die untenseitige Verschraubung an die Außenseite des Drucklufttanks angepresst wird. Die Montage derartiger Systeme ist aufwendig.In practice, other systems are known in which the insert tube also extends from the bottom of the compressed air tank out and has an external thread which is screwed fastened with a female thread having a fitting below the compressed air tank. At the top, the connection is made via a pipe holder, which is pressed by the bottom-side fitting to the outside of the compressed air tank. The installation of such systems is expensive.
BESTATIGUNGSKOPIE Zunächst darf die Verschraubung nicht zu stark angezogen werden, da sonst die Verrippung am Rohrhalter reißt. Bei Druckluftstößen kommt es jedoch zu einer schwellenden Beanspruchung des Tanks, bei der sich dessen Ober- und Unterseite zueinander bewegen. Dabei können dann Leckagen entstehen, durch die Luft unkontrolliert entweichen kann. Das Anziehen der Schraubverbindungen ist daher meist ein iterativer Prozess, und es bleibt schwierig, das Optimum zwischen zu starker und zu lockerer Verschraubung zu erreichen.BESTATIGUNGSKOPIE First, the screw must not be tightened too much, otherwise the ribbing on the tube holder ruptures. In compressed air surges, however, there is a swelling stress on the tank, in which move its top and bottom to each other. This can then cause leaks, can escape uncontrollably through the air. The tightening of the screw is therefore usually an iterative process, and it remains difficult to achieve the optimum between too strong and too loose screw.
Der Erfindung liegt insoweit die Aufgabe zugrunde, Absperrvorrichtungen bzw. entsprechende Tanksysteme zu schaffen, deren Montage vereinfacht und deren Funktionalität verbessert ist.The invention is so far the object of the invention to provide shut-off devices or corresponding tank systems whose assembly is simplified and their functionality is improved.
Erfindungsgemäß wird diese Aufgabe durch eine Absperrvorrichtung mit den Merkmalen des Anspruchs 1 bzw. durch ein Tanksystem mit den Merkmalen des Anspruchs 9 gelöst.According to the invention this object is achieved by a shut-off device with the features of claim 1 and by a tank system with the features of claim 9.
Die erfindungsgemäße Ausbildung der Absperrvorrichtung als Stecksystem, wobei die Absperrvorrichtung in den Drucklufttank lediglich von oben, d.h., steuerseitig eingesteckt werden muss und dort formschlüssig gehalten wird, erübrigt aufwendige Schweißverbindungen oder Schraublösungen, für die auch meist die Rückseite des Drucklufttanks zugänglich sein muss. Bevorzugt ist dazu der Rohrhalter mit dem Speichertank werkzeuglos, jedoch druckfest verbindbar ausgestaltet. Dies kann beispielsweise durch eine Rastverbindung zwischen Rohrhalter und Speichertank erreicht werden. Es ist jedoch auch zum Beispiel eine Bajonettverbindung möglich, die evtl. noch zusätzlich von Rastelementen und/oder federvorgespannte Lagerpositionen einnehmenden Verbindungsteilen unterstützt werden kann. Weitere Vorteile und Einzelheiten ergeben sich aus den Unteransprüchen und einem in der Zeichnung dargestellten Ausführungsbeispiel der Erfindung, das im folgenden beschrieben wird; es zeigen:The inventive construction of the shut-off device as a plug-in system, the shut-off device in the compressed air tank only from above, ie, must be inserted in the control side and is held there form-fitting, eliminates complex welds or Schraublösungen, for which usually the back of the compressed air tank must be accessible. Preference is given to the pipe holder with the storage tank without tools, but designed pressure-resistant connectable. This can be achieved for example by a latching connection between pipe holder and storage tank. However, it is also possible, for example, a bayonet connection, which may possibly be additionally supported by locking elements and / or spring-loaded bearing positions engaging connecting parts. Further advantages and details emerge from the subclaims and an embodiment of the invention shown in the drawing, which will be described below; show it:

Fig. 5 eine Ansicht aus Richtung V auf den Gegenstand aus Fig. 4.5 is a view from the direction V on the article of FIG. 4th
Das dargestellte Tanksystem hat einen Drucklufttank 1, der bevorzugt aus einem gezogenen Aluminiumprofil 2, das die umfangseitigen Wandungen ausbildet, sowie beidseitigen Abschlusselementen 3 besteht, die den Drucklufttank 1 stirnseitig verschließen. Die Oberseite des Drucklufttanks 1 weist in definierten Abständen Durchführöffnungen 4 auf, durch die die erfindungsgemäßen Absperrvorrichtungen eingesteckt werden können, wie nachfolgend beschrieben.The tank system shown has a compressed air tank 1, which preferably consists of a drawn aluminum profile 2, which forms the peripheral walls, and two-sided end elements 3, which close the compressed air tank 1 frontally. The upper side of the compressed air tank 1 has through openings 4 at defined intervals, through which the shut-off devices according to the invention can be inserted, as described below.
Die einzelnen Absperrvorrichtungen bestehen jeweils aus einem Einsatzrohr 6, das bevorzugt aus Aluminium oder Edelstahl gefertigt ist, da die mit ihm aus dem Inneren 1' des Drucklufttanks 1 in Kontakt tretenden Elemente neben Luft auch Kontami- nationsanteile wie Staub und teilweise aggressive Anteile wie Schwefel, Säurebildner und Ölbestandteile eines Kompressors etc. enthalten können. Das Einsatzrohr 6 ist von einem Rohrhalter 7 gehalten. Bei der dargestellten Ausführungsform erfolgt die Abdichtung der beiden Bauteile 6,7 gegeneinander über eine Dichtung (O-Ring 8), die genug Selbsthemmung aufbringt, dass die beiden Bauteile 6,7 bei der Montage nicht auseinanderrutschen können. Das Einsatzrohr 6 und der Rohrhalter 7 müssen jedoch nicht zwingend zwei separate Bauelemente sein, sondern können auch einstückig ausgebildet sein. Bei der abgebildeten Ausführungsform hingegen wird der Rohrhalter 7 bevorzugt aus Kunststoff gefertigt, so dass Rohrhalter 7 und Einsatzrohr 6 aus verschiedenen Materialien bestehen, die jeweils optimiert bedarfsgerechte Eigenschaften aufweisen können.The individual shut-off devices each consist of an insert tube 6, which is preferably made of aluminum or stainless steel, since the elements which come into contact with it from the interior 1 'of the compressed-air tank 1 contain not only air but also contaminants. nations parts such as dust and partially aggressive components such as sulfur, acidifiers and oil components of a compressor, etc. may contain. The insert tube 6 is held by a tube holder 7. In the illustrated embodiment, the sealing of the two components 6, 7 takes place against each other via a seal (O-ring 8) which applies enough self-locking that the two components 6, 7 can not slip apart during assembly. However, the insert tube 6 and the tube holder 7 need not necessarily be two separate components, but may also be integrally formed. In the illustrated embodiment, however, the tube holder 7 is preferably made of plastic, so that tube holder 7 and insert tube 6 consist of different materials, each of which can have optimized needs-based properties.
Der Rohrhalter 7 ist wie dargestellt so ausgebildet, dass er mit dem Speichertank 1 werkzeuglos verbindbar ist, nämlich durch reines Einstecken von der Oberseite des Speichertanks 1 aus durch die Durchführöffnung 4. Dabei taucht das untere Ende des Einsatzrohres 6, das mit einer weiteren Abdichtung (O-Ring 9) versehen ist, in eine Einstecköffnung 10 des Speichertanks 1 ein, die sich nach innen verjüngt und damit ein Widerlager 11 für das dem Rohrhalter 7 gegenüberliegende Ende des Einsatzrohrs 6 bildet. Unterhalb der Verjüngung mit dem Widerlager 11 schließt sich ein Anschlussbereich 12 an, über den individuell angepasste Anschlüsse für die Funktion des Tanksystems erfolgen können, beispielsweise Düsen zur Abreinigung von Luftfiltern. Die Einstecköffnung 10 ist bevorzugt wie dargestellt so tief auszubilden, dass auch bei schwellender Beanspruchung des Speichertanks 1 und/oder einer leichten Verschiebung des Einsatzrohres 6 in Längsrichtung eine Abdichtung gewährleistet bleibt. Zur Verbindung von Einsatzrohr 6 und Rohrhalter 7 mit dem Drucklufttank 1 hat der Rohrhalter 7 bei der dargestellten Ausführungsform Befestigungselemente, die beim Rohrhalter als federnde Rastarme 17 ausgebildet sind und im Einbauzustand als Gegenbefestigungsmittel einen ein Widerlager bildenden Vorsprung 14 der Durchführöffnung 4 in der Wandung des Speichertanks 1 rastend hintergreifen. In Fig. 2 ist die Befestigung des Einsatzrohres 6 mit Rohrhalter 7 im rechten Teil der Abbildung verdeutlicht, wo die beiden Elemente von oben durch die Durchführöffnung 4 hindurchgesteckt werden. Dabei geben die Rastarme 17, die im unbelasteten Zustand eine sich entgegen der Befestigungsrichtung B von unten nach oben erweiternde Kontur ausbilden, elastisch federnd nach und legen sich an den oberen Bereich des Rohrhalters 7 an. Ist der Rohrhalter 7 mit seinem unteren Ende schließlich vollständig in die Einstecköffnung 10 hineingesteckt, federn die oberen Enden der Rastarme 17 mit ihrem maximalen Federweg nach außen zurück und rasten hinter dem Vorsprung 14 der Durchführöffnung 4 in eine entsprechende umlaufende Ausnehmung ein, wie in den Fig. 1 und 3 an der jeweils linken Absperrvorrichtung dargestellt. Anschließend wird auf dem Rohrhalter 7, der in seinem oberen Bereich gleichzeitig einen umlaufenden Membransitz 13 ausbildet, eine Ventilmembran 15 aufgelegt, die abschließend mit einem Membrandeckel 16 fixiert wird. Der Ventilsitz kann auch (hier nicht dargestellt) in einem separaten Bauteil ausgebildet sein.The tube holder 7 is as shown formed so that it can be connected to the storage tank 1 without tools, namely by pure insertion from the top of the storage tank 1 through the passage opening 4. This immersed the lower end of the insert tube 6, which with a further seal ( O-ring 9) is provided in an insertion opening 10 of the storage tank 1, which tapers inwardly and thus forms an abutment 11 for the tube holder 7 opposite end of the insert tube 6. Below the taper with the abutment 11 is followed by a connection area 12, via which individually adapted connections for the function of the tank system can take place, for example nozzles for cleaning air filters. The insertion opening 10 is preferably formed as deep as shown, that even with swelling stress of the storage tank 1 and / or a slight displacement of the insert tube 6 in the longitudinal direction a seal remains ensured. To connect the insert tube 6 and tube holder 7 with the compressed air tank 1, the tube holder 7 in the illustrated embodiment fastening elements which are formed as resilient latching arms 17 and the pipe holder as a counter-fastening means an abutment-forming projection 14 of the passage opening 4 in the wall of the storage tank 1 latching behind. In Fig. 2, the attachment of the insert tube 6 is illustrated with tube holder 7 in the right part of the figure, where the two elements are inserted from above through the passage opening 4. In this case, the latching arms 17, which in the unloaded state form a contour widening from the bottom upwards against the fastening direction B, elastically yield and lie against the upper area of the pipe holder 7. If the tube holder 7 is finally inserted with its lower end completely into the insertion opening 10, the upper ends of the latching arms 17 spring back outwards with their maximum spring travel and engage behind the projection 14 of the lead-through opening 4 into a corresponding circumferential recess, as shown in FIGS 1 and 3 are shown on the left-hand shut-off device. Subsequently, a valve membrane 15 is placed on the tube holder 7, which simultaneously forms a circumferential diaphragm seat 13 in its upper region, which is finally fixed with a diaphragm cover 16. The valve seat may also be formed (not shown here) in a separate component.
Im Funktionszustand der Absperrvorrichtung wird in die vorgesehenen Halterungen des Membrandeckels 16 ein Steuerelement, beispielsweise eine Magnetankersteuerung eingesetzt, über die die nach unten vorgespannte Ventilmembran 15 angehoben werden kann. Dabei hebt sich die Ventilmembran 15 vom Membransitz 13 ab, und aus dem Inneren 11 des Drucklufttanks 1 strömt Druckluft zwischen den Rastarmen 17 und dem Membransitz 13 sowie der Ventilmembran 15 entlang durch das Innere des Einsatzrohres 6 und die Einstecköffnung 10 nach außen aus dem Drucklufttank 1 hinaus.In the functional state of the shut-off device, a control element, for example a magnetic armature control, is used in the provided holders of the membrane cover 16, via which the valve membrane 15 biased downwards can be raised. In this case, the valve diaphragm 15 lifts off from the diaphragm seat 13, and from the interior of the compressed air tank 1 1 1 compressed air flows between the locking arms 17 and the diaphragm seat 13 and the valve diaphragm 15 along the Inside the insert tube 6 and the insertion opening 10 to the outside of the compressed air tank 1 addition.
Die dargestellte Ausführungsform, bei der Einsatzrohr 6 und Rohrhalter 7 lediglich von oben in den Drucklufttank eingesteckt und an dessen Wandungen verrastet bzw. eingeklipst werden müssen, um einen sicheren Halt zu erhalten, ist für eine einfache Montage von besonderem Vorteil. Dabei müssen die Befestigungs- bzw. Rastelemente jedoch nicht zwingend am Rohrhalter 7 vorgesehen sein, sondern können auch umgekehrt im/am Drucklufttank ausgebildet sein, und mit Ausnehmungen des Rohrhalters 7 bzw. des Einsatzrohres 6 verrasten. Die abgebildete Ausführungsform wird jedoch bevorzugt, da sowohl die Montage als auch eine eventuelle Demontage, z.B. zum Austausch eines korrodierten Einsatzrohres 6, bei der dargestellten Ausführungsform einfacher zu verwirklichen ist. Anstelle einer rastenden bzw. einklipsenden Steckmontage können auch Bajonettverbindungen, ggf. mit fakultativ zusätzlicher Verrastung, vorgesehen sein. Auch ist ein reines Einschrauben von Einsatzrohr 6 und/oder Rohrhalter 7, ggf. mit selbsthemmender Gewindesteigung, vorstellbar.The illustrated embodiment, in which insert tube 6 and tube holder 7 only inserted from above into the compressed air tank and latched or clipped on the walls thereof in order to obtain a secure fit, for a simple installation of particular advantage. However, the fastening or latching elements need not necessarily be provided on the tube holder 7, but may also be formed conversely in / on the compressed-air tank, and latch with recesses of the tube holder 7 and the insert tube 6. However, the illustrated embodiment is preferred because both the assembly and eventual disassembly, e.g. to replace a corroded insert tube 6, in the illustrated embodiment is easier to implement. Instead of a latching or einklipsenden plug assembly and bayonet connections, possibly with optional additional locking can be provided. Also, a pure screwing of insert tube 6 and / or tube holder 7, possibly with self-locking thread pitch, conceivable.
Da es bei dem erfindungsgemäßen Tanksystem zur Montage lediglich des Einste- ckens der Absperrvorrichtungen von oben bedarf, ohne dass diese an der Unterseite des Drucklufttanks 1 herausragend gegenfixiert werden müssen oder dergleichen, wird die minimale Abstandbreite zwischen zwei Absperrvorrichtungen auch lediglich durch deren obere Abmessungen bestimmt. Um noch möglichst kleine Abstandmaße zweier Absperrvorrichtungen voneinander verwirklichen zu können, ist es daher von Vorteil, jeweils benachbarte Membrandeckel 16 gegeneinander verdreht am Speichertank 1 zu befestigen, wie es in den Fig. 1 und 5 erkennbar ist. Besonders bevorzugt hat dabei jeder Membrandeckel 16 eine ungerade Anzahl von Verbin- dungslöchern 19, insbesondere wie dargestellt genau drei Stück, und benachbarte Membrandeckel 16 sind jeweils um 180° um die Längsachse der Absperrvorrichtung verdreht gegeneinander am Speichertank 1 festgelegt. Dies ermöglicht sehr kleine Bauformen bei gleichzeitig solider Befestigung.Since the tank system according to the invention requires only the insertion of the shut-off devices from above, without these having to be fixed in an outstanding manner against the underside of the compressed-air tank 1 or the like, the minimum distance between two shut-off devices is also determined only by their upper dimensions. In order to be able to realize each other as small as possible distance dimensions of two shut-off devices, it is therefore advantageous, each adjacent diaphragm cover 16 against each other twisted secured to the storage tank 1, as can be seen in Figs. 1 and 5. In this case, each diaphragm cover 16 particularly preferably has an odd number of connections. Aperture holes 19, in particular as shown exactly three pieces, and adjacent membrane cover 16 are each rotated by 180 ° about the longitudinal axis of the shut-off against each other at the storage tank 1. This allows very small designs with solid attachment.
Die erfindungsgemäße Absperrvorrichtung und das entsprechende Tanksystem zeichnen sich durch eine stark vereinfachte Montage bei gegenüber herkömmlichen Systemen mindestens gleichwertiger Funktionalität aus, so dass das Gesamtsystem auch geringere Kosten verursacht. The shut-off device according to the invention and the corresponding tank system are characterized by a greatly simplified assembly with respect to conventional systems at least equivalent functionality, so that the overall system also causes lower costs.
