Erfindungsgemäss ist die Schiebereinheit 30 von mehreren senkrecht zu ihrer Längserstreckung verlaufenden Haltemitteln 40 längsverschiebbar am Gehäuseteil 14 gehalten, wobei diese Haltemittel 40 jeweils am Gehäuseteil 14 befestigt sind und gegenüberliegend ein Führungsmittel aufweisen, welches jeweils auf einer an der Schiebereinheit 30 ausgebildeten Führungsbahn 36 gleitet.According to the invention, the slide unit 30 is perpendicular to several of them Holding means 40 extending longitudinally longitudinally on Housing part 14 held, these holding means 40 each on the housing part 14 are attached and have a guide means opposite, which each on a guideway formed on the slide unit 30 36 slides.

Zweckmässigerweise sind beidseitig zu den Verschlussplatten 22, 23 je zwei Haltemittel 40 vorgesehen, welche symmetrisch zur Ausgussöffnung 12 des Behälters angeordnet sind und jeweils ein senkrecht zur Längserstreckung des Gehäuseteils 14 bzw. der Schiebereinheit 30 verlaufendes bolzenförmiges Verbindungsglied 25 aufweisen. Diese Verbindungsglieder 25 sind jeweils in ihrer Achsrichtung verstellbar im Gehäuseteil 14 gehalten und an ihren jeweiligen oberen Kopfscheiben 25' von einem als Druckfeder ausgebildeten Federorgan 26 beaufschlagt, wobei letzteres in einer Büchse 28 eingekapselt ist. Am unteren Ende der Verbindungsglieder 25 sind paarweise je zwei als Führungsmittel vorgesehene Gleitrollen 27 drehgelagert, auf welchen die Schiebereinheit 30 längsgeführt ist. Letztere hat zu diesem Zwecke beidseitig zu der in ihr einsetzbaren Verschlussplatte 23 je eine in ihrer Verschieberichtung verlaufende T-nutenförmige Ausnehmung 33, in der je zwei Führungsbahnen 36 ausgebildet sind. Diese symmetrische Anordnung der Gleitrollenpaare zur Wirkungslinie der durch das Federorgan 26 erzeugten Federkraft ermöglicht eine optimale Kraftübertragung von den Haltemitteln 40 auf die Schiebereinheit 30 und nachfolgend auf die gegeneinander anzupressenden Platten 22, 23.Appropriately, there are two on both sides of the closure plates 22, 23 Holding means 40 are provided which are symmetrical to the pouring opening 12 of the Container are arranged and each perpendicular to the longitudinal extent of the housing part 14 or the slide unit 30 extending bolt-shaped Have link 25. These links 25 are each held and adjustable in its axial direction in the housing part 14 their respective upper head disks 25 'by a compression spring Spring member 26 acts, the latter in a sleeve 28th is encapsulated. At the lower end of the connecting links 25 are in pairs Two slide rollers 27, which are provided as guide means, are rotatably mounted on each the slide unit 30 is longitudinally guided. The latter has for this purpose on both sides of the closure plate 23 that can be inserted into it, one in its direction of displacement running T-groove-shaped recess 33, in each of two Guideways 36 are formed. This symmetrical arrangement of the Coupling roller pairs to the line of action of those generated by the spring element 26 Spring force enables optimal power transmission from the holding means 40 on the slide unit 30 and subsequently on those to be pressed against each other Plates 22, 23.

Gemäss Fig. 2 sind die seitlich in der Schiebereinheit 30 als Unsichtbare veranschaulichten T-nutenförmigen Ausnehmungen 33 je in der Mitte und endseitig mit einer erweiternden Öffnung 33' versehen, welche derart bemessen und zueinander ausgebildet sind, dass die Verbindungsglieder 25 zusammen mit den Gleitrollen 27 in diese einschiebbar sind bzw. aus diesen herausgenommen werden können.According to FIG. 2, they are laterally in the slide unit 30 as invisible illustrated T-groove-shaped recesses 33 in the middle and provided at the end with a widening opening 33 'which is dimensioned in this way and each other, that the connecting links 25 can be inserted into and out of these together with the guide rollers 27 can be removed.

Fig.3 zeigt die Führungsbahnen 36, die endseitig bei den Öffnungen 33' je eine Rampe 36' mit einer solchen Höhe aufweisen, dass sich die Federorgane 26 beim Auffahren auf den Betriebsdruck verspannen bzw. beim Lösen komplett entspannen. Für das Lösen wird die Schiebereinheit 30 in eine ausserhalb der Offen- und der Schliessstellung des Verschlusses 20 liegende Position verschoben, bei der sich die Schiebereinheit vom Federdruck löst, bis sie sich mit ihren Öffnungen 33' oberhalb der Gleitrollen 27 befindet und sie dann freigegeben ist. Hierbei gelangen seitlich an der Schiebereinheit 30 angeordnete Scharnierteile 37 mit ihren Bohrungen in entsprechende Scharnierbolzen 38 am Gehäuseteil 14, wodurch die Schiebereinheit 30 ausgeschwenkt werden kann. Sie ist hierbei mittels Klauen 41 oder dergleichen an einer Schubstange 42 eines als Hydraulik-Zylinder ausgebildeten Antriebsorganes 19 angekuppelt. Diese Klauenkupplung ermöglicht als weiterer Vorteil ein selbsttätiges Lösen der Schiebereinheit 30 von der Schubstange 42.3 shows the guideways 36, the ends of each of the openings 33 ' have a ramp 36 'with a height such that the spring members 26 tension when approaching the operating pressure or when loosening relax completely. For the release, the slide unit 30 is in an outside the open and the closed position of the closure 20 lying Position shifted at which the slide unit releases from the spring pressure, until it is above the slide rollers 27 with its openings 33 ' and then it's released. Here you get to the side of the slide unit 30 arranged hinge parts 37 with their holes in corresponding Hinge pin 38 on the housing part 14, whereby the slide unit 30 is pivoted out can be. It is here by means of claws 41 or the like on a push rod 42 of a drive element designed as a hydraulic cylinder 19 coupled. This claw coupling allows as another The advantage of an automatic release of the slide unit 30 from the push rod 42nd

Das Scharnier 37, 38 könnte auch auf der anderen Seite der Schiebereinheit 30 oder an der kürzeren, dem Antrieb abgewandten Seite angeordnet sein. The hinge 37, 38 could also be on the other side of the slide unit 30 or on the shorter side facing away from the drive.

Demnach kann die Schiebereinheit je nach Plazierung des Verschlusses am Pfannenausguss auf eine der drei Seiten ausgeschwenkt werden. Da bei vielen Anwendungsfällen die Verschieberichtung der Schiebereinheit am Montageplatz in vertikaler Richtung verläuft, kann die Schiebereinheit in der dargestellten Anordnung horizontal geschwenkt werden, was mit wenig Kraftaufwand verbunden ist.Accordingly, the slide unit can, depending on the placement of the closure Pan spout can be swung out on one of the three sides. There with many Applications, the direction of displacement of the slide unit at the assembly site runs in the vertical direction, the slide unit in the shown arrangement can be pivoted horizontally, what with little Force is connected.

Die beiden jeweils auf einer Seite der Verschlussplatten 22, 23 befindlichen Haltemittel 40 sind zur Stabilisierung gegen die auftretenden Biegekräfte durch wenigstens eine Verbindungsstange 31, 32 versteift und sie bilden dadurch eine Wagenform. Die vorliegend vorgesehenen beiden Verbindungsstangen 31, 32 befinden sich zentrisch in der Ausnehmung 33. Sie weisen eine Breite auf, die annähernd derjenigen der Verbindungsglieder 25 entsprechen, so dass dieselben in bzw. aus der Ausnehmung 33 ein- bzw. herausgeführt werden können. Die Verbindungsglieder 25 sind ferner zweigeteilt und durch eine Feder/Nut-Verbindung 25" oder dergleichen zusammengefügt. Auf diese Verbindungsstangen 31, 32 könnte im Prinzip auch verzichtet werden. Anstelle der Gleitrollen 27 könnten Gleitsteine benutzt werden.The two located on one side of the closure plates 22, 23 Holding means 40 are for stabilization against the bending forces that occur stiffened by at least one connecting rod 31, 32 and thereby form a car shape. The two connecting rods provided here 31, 32 are located centrally in the recess 33. They point a width which approximately corresponds to that of the connecting links 25, so that they are inserted into and out of the recess 33 can be. The connecting links 25 are further divided into two and assembled by a tongue and groove connection 25 "or the like. In principle, these connecting rods 31, 32 could also to be dispensed with. Instead of the sliding rollers 27, sliding blocks could be used become.

Als weiterer Vorteil können diese Haltemittel 40 im Rahmen der Erfindung bei ausgeschwenkter Schiebereinheit 30 seitlich vom Gehäusteil 14 paketweise weggenommen werden. Im Gehäuseteil 14 sind zu diesem Zwecke entsprechende Aussparungen 15 vorhanden, in welche die Haltemittel passend eingeschoben werden können. Hieraus lassen sich die Federorgane 26 für die öfters notwendigen Überprüfungen ihrer Spannkraft schnell wegnehmen und wieder einsetzen. As a further advantage, these holding means 40 can be used within the scope of the invention with the slider unit 30 pivoted out laterally from the housing part 14 in packets be taken away. Corresponding are in the housing part 14 for this purpose Recesses 15 are available in which the holding means fit can be inserted. From this, the spring members 26 for the quickly remove the necessary checks of their tension and reinstate.

Gemäss Fig.4 sind der Schiebereinheit 30 in ihrer Mittelpartie Quer- und Längsrippen 30' zugeordnet, welche zur Verstärkung derselben gegen Verbiegung und Torsionskräfte dienen. Der Schiebeverschluss 20 ist im übrigen in der geschlossenen Position veranschaulicht.4, the slide unit 30 are transverse and in its central part Longitudinal ribs 30 'assigned, which reinforce the same against bending and serve torsional forces. The slide closure 20 is otherwise illustrated in the closed position.

Fig.5 zeigt eine Variante eines Schiebeverschlusses 50, welcher an sich ähnlich wie derjenige nach Fig.1 aufgebaut ist. Es sind daher nachfolgend nur gerade die Unterschiede näher erläutert. Dieser Schiebeverschluss 50 hat wiederum einen am Behälter befestigten Gehäuseteil 54, in welchem eine stationäre feuerfeste Verschlussplatte 22 enthalten ist. Die Haltemittel 65 sind als wesentlicher Unterschied gegenüber dem Verschluss 20 nicht im Gehäuseteil 54, sondern an der Schiebereinheit 60 befestigt. Die axial bewegbaren Verbindungsglieder 55 sind zusammen mit den aus mehreren Tellerfedern gebildeten Federorganen 66 in einer Aussparung 61 der Schiebereinheit 60 gehalten. Als Führungsmittel sind den vorteilhaft wiederum vier Verbindungsgliedern 55 jeweils eine an einer horizontalen Achse 69 drehbare Gleitrolle 68 zugeordnet, welche auf einer analog zu derjenigen nach Fig.3 ausgebildeten Führungsbahn 71 am Gehäuseteil 54 gleitet. Die beiden seitlich am Gehäuseteil vorgesehenen Führungsbahnen 71 erstrecken sich in Verschieberichtung der Schiebereinheit und sie sind mit nicht näher gezeigten Rampen versehen, welche zum Be- bzw.

Diese Schiebeverschlüsse 20, 50 können somit aufgrund dieser erfindungsgemässen Ausbildung in ihren Dimensionen kleinstmöglich gehalten werden, sei es mit Bezug auf die Bauhöhe wie auch auf dessen Länge und Breite. Hieraus ergibt sich auch eine kostengünstigere Herstellung desselben. Dieser Verschluss kann sowohl in kleineren Dimensionen für kleinere Pfannen mit bis zu 100 Tonnen Fassungvermögen als auch in grösseren Dimensionen für 300 Tonnen-Pfannen hergestellt werden.In the inventive slide closures 20, 50 each have both the housing part 14, 54 and the slide unit 30, 60 each have a plate-like training and they are in the operating state arranged parallel and at a short distance from each other. These sliding closures 20, 50 can therefore be based on these according to the invention Training in its dimensions can be kept as small as possible, be it with Regarding the overall height as well as its length and width. From this results a cheaper production of the same. That closure can be used both in smaller dimensions for smaller pans to 100 tons capacity as well as in larger dimensions for 300 Barrel pans are made.

Im Prinzip könnte das erforderliche Federpaket für das Verspannen der feuerfesten Platten gegeneinander in an sich bekannter Weise zwischen der Schieberplatte und der Schiebereinheit vorgesehen sein. Die Haltemittel könnten dementsprechend nicht verschiebbar im Gehäuseteil oder in der Schiebereinheit angeordnet sein.In principle, the spring package required for bracing the refractory could Plates against each other in a manner known per se between the Slider plate and the slide unit can be provided. The holding means could accordingly not be displaceable in the housing part or in the Slider unit can be arranged.
