Description
Umsteuerschieber für Regenerativäfen od. dgl. Die Umsteuerschieber für Regenerativöfen werden vielfach als Schrägschieber ausgeführt, die gleitend in die Verschlußlage gebracht «-erden. Es kann aber bei diesen Schiebern vorkommen, daß sich Fremdkörper an den Auflagekanten befinden. die dann den vollständigen Schluß des nur durch einen Anteil seines Eigengewichtes angedrückten Schielfers verhindern. Sehr oft ist mit einer solchen Undichtigkeit außer dein Verlust an Gas oder Wärme tragenden Mitteln auch noch eine Explosionsgefahr verbunden, dadurch das Luft und explosible Gase zusammentreten können.Reversing slides for regenerative ovens or the like. The reversing slides for regenerative ovens are often designed as inclined slides that slide into the closed position. However, with these slides it can happen that there are foreign bodies on the support edges. which then prevent the complete closure of the squint, which is only pressed by a portion of its own weight. Very often such a leak is not only associated with the loss of gas or heat-carrying agents, but also with a risk of explosion, which can cause air and explosive gases to come together.
Die Erfindung betrütt eine neue Ausbildung eines solchen welche einen dichten -,Mbschluß mit großer Sicherheit herbeiführt, weil nicht nur ein Eigengewicbtsantei-l der Schieberplatte zur Erzielung des Auflagedruckes in der Abschlußstellung benutzt wird, sondern auch ein weiterer Druck, der beispielsweise durch Federn, Gewichte od. d g1. ausgeübt «-erden kann. Das wird dadurch erzielt, daß die Schieberplatte mit einem Anschlag od. dgl. an einer federnd angedrückten Führung in die Zerschlußstellung bewegt wird. Die federnd angedrückte Führung ist also dauernd bestrebt, die Platte an i'h-ren Sitz zu pressen.The invention is a new development of such a thing dense -, brings about a connection with great certainty, because not only an inherent part of the weight the slide plate used to achieve the contact pressure in the final position is, but also another pressure, for example by springs, weights or. d g1. exercised «- can be. This is achieved in that the slide plate with a stop or the like on a resiliently pressed guide in the locked position is moved. The resiliently pressed guide is therefore constantly striving to the plate to press against their seat.
Z«-ecl@inäßig wird man den Anschlag durch Rollen bilden, so daß der Schieber leicht bewegt «-erden kann. Bevorzugt wird die Anwendung der Rollen etwa in der Mitte der Sc=hieberplatte, so daß die federnde Andrückung über die Rollen ähnlich wie ein Balancier wirkt, also im wesentlichen gleiche Andrüekkräfte auf der ganzen D-ichtungsfläche hervorruft. Damit ist ein wesentlich vervollkommneter Absc'hluß erzielt. Überdies wird auch der Verschleiß an den Dichtungsflächen durch Einschaltung der federnd angedrückten Führung und der Anschläge, insbesondere Rollen, vermindert.Z «-ecl @ inäßig one will form the stop by rolling, so that the Slider moved easily «- can be earthed. The use of roles is preferred in the middle of the valve plate, so that the resilient pressure on the rollers acts similarly to a balancer, i.e. essentially the same pressure forces of the entire sealing surface. This is a much more perfect one Completion achieved. Moreover, will also the wear on the sealing surfaces by switching on the resiliently pressed guide and the stops, in particular Roles, diminished.
Bei der bisherigen Ausführung der Schieber mußte eine erhebliche Neigung (etwa 21°) angewendet «-erden, damit der Schieber durch sein Gewicht möglichst dicht aufliegt. Dieses Gewicht wirkt dann aber auch auf dem gesamten Wieg des Schiebers, so d'aß sich leicht Rillen od. dgl'. in die Dichtungsflächen unbeabsichtigt einarbeiten. Bei der neuen Erfindung wird der Abdichtungsdruck im wesentlichen durch die an der Führung angreifenden Federn bewerhstell@igt, so daß die Schieberplatte nahezu senkrecht gestellt werden kann und der erforderliche Druck erst vor Erreichung der Abschlußstellung an der Verschlußpl-atte und den Dichtungsflächen auftritt. DieRillenbildung wird damit praktisch aufgehoben.In the previous version of the slide, there had to be a considerable inclination (approx. 21 °) applied «- earth so that the slider is as tight as possible due to its weight rests. This weight then also acts on the entire cradle of the slide, so that there are easily grooves or the like. unintentionally work into the sealing surfaces. In the new invention, the sealing pressure is essentially by the Lead acting springs bewerhstell @ igt so that the slide plate is almost vertical can be provided and the required pressure only before reaching the final position occurs on the sealing plate and the sealing surfaces. The grooving will practically canceled.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt.An exemplary embodiment of the invention is shown in the drawing.
Abb. i zeiht einen Längsschnitt durch den Sc=hieber, Abh. 2 einen Ouerschnitt dazu.Fig. I shows a longitudinal section through the slide, Fig. 2 one Cross-section to this.
Die Schieberplatte i läuft mit dem Rollenpaar 2 (Abb. 2) an der Bahn to entlang. Ein weiteres Rollcnpa,ar 3 wirkt mit den Führungsbahnen 4. der um die Achse 5 drehbaren Hebel 6 zusammen. Auf das obere Ende der Hebel wirken die Federn 7 über die Zugstangen S. Durch die Muttern 9 od. dgl. ist die Federspannung von außen her einstellbar. Wenn der Schieber abgelassen wird, dann laufen die Rollen 2 auf den Bahnen to und die Rollen 3 auf den Bahnen 4 entlang. Sobald die S.chieberplatte i in die Schließstellung gelangt, gleiten die Rollen 2 in Vertiefungen i i der Bahnen to hinein, so daß diese Rollen frei gehen, wie auch aus der Abb. 2 ersichtlich ist. Die Sch ieberp,latte wird dann von den Federn 7 über die Hebel 6 und d:ie Rollen 3 an die Widerlager 12 gepreßt.The slide plate i runs with the pair of rollers 2 (Fig. 2) on the track to along. Another Rollcnpa, ar 3 acts with the guideways 4. the around the Axis 5 rotatable lever 6 together. The springs act on the upper end of the levers 7 over the tie rods S. By the nuts 9 or the like. The spring tension of adjustable from the outside. When the slide is lowered, the rollers run 2 on the tracks to and the rollers 3 on the tracks 4 along. As soon as the slide plate i reaches the closed position, the rollers 2 slide in recesses i i of the tracks to into it, so that these roles go freely, as can also be seen from Fig. 2. The slider is then driven by the springs 7 via the levers 6 and the rollers 3 pressed against the abutment 12.
An Stelle von je zwei auf einer Schieberseite lose um eine gemeinsame Achse drehbaren Rollen kann auch nur eine Rolle angeordnet sein, die dann jedoch mindestens während des unteren Teiles des Schieberhubes, gleichzeitig die Fü'hrungsbaÜnen to und 4 berührt, so däß zwei entgegengesetzte Umfangskräfte auf die Rolle einwirken, die ihre Drehung behindern. Der beim Gleiten der Rollen auftretende Reibungswiderstand muß dann von dem Gewicht der Schieberplatte überwunden werden. Stellt sich 'heraus, daß die Pressung nicht ausreichend ist, so kann jederzeit von außen 'her an den Muttern 9 eine Erhöhung der Federkraft vorgenommen werden. Umgekehrt kann jederzeit von außen wahrgenommen werden, welchem Druck die Platte unter Versch.lußstellung ausgesetzt ist.Instead of two on each slide side loosely around a joint Axis rotatable rollers can also be arranged only one roller, but then At least during the lower part of the slide stroke, the guide rails at the same time touches to and 4, so that two opposing circumferential forces act on the roller, that hinder their rotation. The frictional resistance that occurs when the rollers slide must then be overcome by the weight of the slide plate. Turns out, that the pressure is not sufficient, so can at any time from the outside 'to the Nuts 9 an increase in the spring force can be made. The reverse can be done at any time can be perceived from the outside, which pressure the plate under lock position is exposed.
Gegebenenfalls können die Federn auch durch Gewichte ersetzt werden. Auch diese Gewichte können regulierbar sein, beispielsweise indem sie längs eines Hebels verstellbar gemacht werden.If necessary, the springs can also be replaced by weights. These weights can also be adjustable, for example by moving them along a Lever can be made adjustable.
