Description
Verfahren sus Betrieb eines Verschluß-Schiebers fUr Vorrichtungen zum Durchla# von vorzugsweise körnigem Gut, beispielsweise bei Betonfordermaschinen oder dergleichen sowie Schieber zur Durchführung des Verfahrens. Method for the operation of a locking slide for devices for the passage of preferably granular material, for example in concrete conveyor machines or the like, as well as sliders for carrying out the method.
Die vorliegende Erfindung bezieht sich auf ein Verfahren sua Betrieb eines Verschluß-Schiebers für Vorrichtungen sua Durchla# son vorzugsweise körnigem Gut, beispielaweise bei Betonfördermaschinen oder dergleichen sowie Schieber sur Durchführung des Verfahrens.The present invention relates to a method of operation a locking slide for devices sua passageway, preferably granular Good, for example with concrete hoisting machines or the like and slide sur Implementation of the procedure.
Insbesondere bei der Förderung son großkornigem Gut sowie insbesondere beispielsweise beim Verpressen son Beton treten an den Ausgabeoffnungen erhebliche Schwierigkeiten dadurch auf, da# die entsprechenden Verschluß-Schieber gro#en Drücken auagesetzt sind und dabei zwangsläufig bei der Bevegung der entsprechenden Schieberplatte einem gans erheblichen Verschleiß ausgesetzt sind. Hierbei ist insbesondere auch su beachten daß bei den hohen Drücken entsprechend kompenaierende Abdichtungsdrucke erforderlich sind, so da# bei den bisher bekannten Schiebern ein solch gro#er Abrieb auftrat, daB schon. nach einer verhältnismäßig kursen Betriebsseit die einwandfreie Funktion des Schiebers nicht mehr gewährleistet werden konnte.In particular when promoting large-grain goods as well as in particular For example, when grouting concrete, there is considerable occurrence at the dispensing openings Difficulties arise as a result of the fact that the corresponding locking slides are pressed very heavily are suspended and inevitably when the corresponding slide plate is moved a goose are exposed to considerable wear and tear. This is particularly also See below that at the high pressures correspondingly compensating sealing pressures are necessary, so that such a large amount of wear occurs in the slides known up to now it occurred that already. after a relatively course operating since the flawless Function of the slide could no longer be guaranteed.
Hier setst nun die vorliegende Erfindung ein und bezweckt in einfachster Art und Weise Abhilfe su schaffen.This is where the present invention comes in and aims in its simplest form How to remedy this.
Erreicht wird dieses gemäß der vorliegenden Erfindung dadurch, da# die eigentliche Schieberplatte mittels eines Druckkissens gegen eine zwischengeschaltete Dichtung verspannt wird.This is achieved according to the present invention in that # the actual slide plate by means of a pressure pad against an intermediate one Seal is braced.
Dabei ist es von Vorteil, daß das Druckkissen mit Flüssigkeit oder gasförmigem Medium, vorzugsweise Luft, wird und iber entsprechende Ventile bei Bedarf wieder entlastet werden kann.It is advantageous that the pressure pad with liquid or gaseous medium, preferably air, and via appropriate valves if necessary can be relieved again.
Der erfindungsgemäße Schieber zur Durchführung des Verfahrens wird dabei dadurch gefüllt gekennzeichnet, daß seine Verschlußplatte mit einem Druckkissen susammenwirkt, welche die Verschlußplatte gegen eine Dichtung drückt.The slide according to the invention for performing the method is characterized in that its closure plate is filled with a pressure pad cooperates, which presses the closure plate against a seal.
Durch die erfindungsgemä#e Ausbildung kann praktisch einmal in der Schließstellung diese Schieberplatte mit einem gewünschten Druck gegen den entsprechenden Gegenflansch gepreßt werden und darüber hinaus während des Öffnungsvorganges durch Entlastung des Druckkissens eine leichte Verachiebung der Schieberplatte ermöglichen, so da# der Verschlei# auf ein Minimum herabgedrückt werden kann.The inventive training can practically once in the Closed position this slide plate with a desired pressure against the corresponding Counterflange are pressed and, moreover, through during the opening process Relief of the pressure cushion enable a slight displacement of the slide plate, so that # the wear # can be reduced to a minimum.
Die Erfindung wird anhand einer Zeichnung, die ein beliebiges Ausführungsbeiepiel zeigt, näher erläutert.The invention is based on a drawing that shows any exemplary embodiment shows, explained in more detail.
Zwischen den Anschlußflansch VI und der Schieberplatte III ist eine Dichtung II zwischengeschaltet. Mit IV ist der Druckkörper bzw. das Druckkissen bezeichnet, das nach dem Verschließen durch die Schieberplatte durch Binas des Druckmittels mit einem beliebig einstellbaren Druck gegen den entsprechenden Gegenflansch VI gedrückt wird.Between the connecting flange VI and the slide plate III is a Seal II interposed. With IV is the pressure body or the pressure pad denotes that after closing by the slide plate by binas of the pressure medium with any adjustable pressure against the corresponding counter flange VI is pressed.
Vor dem Offnen des Schiebers wird das Druckkissen durch ein der Binfachheit halber nicht näher dargestelltes Ventil wieder entlastet und der Schieber bzw. die Schieberplatte hebt sich soweit son dc-Gegenflansch ab, da# die Reibung zwischen der Schieberplatte und der Dichtung auf ein Minimuz herabgesenkt wird. Die Beaufschlagung des Druckkissens kann hierbei beliebig sein, und zwar in beispielsweise hydraulischer Art oder auch durch irgendein gasförmiges Medium wie beispielsweise Luft.Before the slide is opened, the pressure pad is opened by one of the simplicity for the sake of not shown valve relieved again and the slide or the The slide plate lifts up so far as the counter flange that the friction between the slide plate and the seal lowered to a minimum will. The application of the pressure pad can be arbitrary here, namely in for example hydraulic type or by any gaseous medium such as for example air.
