The swinging frames each have two vertically disposed sections, the lower and upper ends of which are interconnected by a tension rod(19,20).

Description

Die Erfindung betrifft eine Zweiwalzenmaschine zur Druckbehandlung körnigen Gutes, insbesondere zur Gutbettzerkleinerung oder Kompaktierung bzw. Brikettierung, mit zwei in einem Maschinenrahmen drehbar gelagerten, gegenläufig angetriebenen und durch einen Walzenspalt voneinander getrennten Walzen, von denen wenigstens eine als Loswalze ausgebildet ist, deren Lagerböcke über Hydraulikzylinder am Maschinenrahmen abgestützt sind, wobei wenigstens ein Rahmenteil zwecks Montage/Demontage der Walzen ausschwenkbar bzw. ausklappbar ist.The invention relates to a two-roll machine for pressure treatment granular goods, in particular for comminution or compacting or briquetting, with two in one machine frame rotatably mounted, driven in opposite directions and through a nip separate rollers, at least one of which is designed as a loose roller, the bearing blocks via hydraulic cylinders are supported on the machine frame, at least one Frame part can be swung out for the purpose of assembling / disassembling the rollers or fold out.

Bei Walzenmühlen wird körniges sprödes Mahlgut in den Walzenspalt, durch den die beiden drehbar gelagerten gegenläufig rotierbaren Walzen voneinander getrennt sind, eingezogen und dort einer Druckzerkleinerung unterworfen. Bekannt ist auch die sogenannte Gutbettzerkleinerung im Walzenspalt einer Hochdruck-Walzenmühle bzw. Walzenpresse auch Rollenpresse genannt, bei der die einzelnen Partikel des durch Reibung in den Walzenspalt eingezogenen Mahlgutes in einem Gutbett, d. h. in einer zwischen den beiden Walzenoberflächen zusammengedrückten Materialschüttung bei Anwendung eines hohen Druckes gegenseitig zerquetscht werden.In the case of roller mills, granular, brittle ground material is placed in the roller gap, through which the two rotatably mounted counter-rotating Rollers are separated from each other, drawn in and there one Subjected to pressure reduction. The so-called is also known Material bed size reduction in the nip of a high-pressure roller mill or roller press also called roller press, in which the individual Particles of the ground material drawn into the nip due to friction in a good bed, d. H. in one between the two roller surfaces compressed material when used a high pressure can be crushed.

Bei bekannten Gutbettzerkleinerungs-Rollenpressen ist eine der beiden Walzen als Festwalze ausgebildet, die sich direkt gegen ein Endstück des Maschinenrahmens abstützt, während sich die andere Walze als Loswalze über ihre beiden zugehörigen Lagerböcke gegen zwischen den Lagerböcken und Maschinenrahmen-Endstücken angeordnete Hydraulikzylinder abstützt, mit denen der Walzenanpressdruck aufgebracht wird. Es versteht sich, dass durch die Anwendung des hohen Pressdruckes die Walzenoberflächen einem hohen Verschleiß ausgesetzt sind. Schon aus diesem Grund gibt es einen Bedarf, auch seitens des Betreibers derartiger Gutbettzerkleinerungs-Rollenpressen, die Walzen in möglichst einfacher und schneller Weise ausbauen und wieder einbauen zu können.In known material bed crushing roller presses is one of the two Rollers designed as a fixed roller, which is directly against an end piece of the machine frame while the other Roll as a loose roller against its two associated bearing blocks arranged between the pedestals and machine frame end pieces Hydraulic cylinder supports with which the roller contact pressure is applied. It is understood that through the application the high pressing pressure the roller surfaces a high Are subject to wear. For this reason alone there is one Requirement, also on the part of the operator of such material bed crushing roller presses, the rollers in as simple and quick as possible Way to expand and reinstall.

Bei Rollenpressen ist es bekannt (Broschüre "HRP Hydraulic Roller Press" der Fuller Corporation von 7/95), einen Teil des Maschinenrahmens als L-förmigen Schwenkrahmen auszubilden. Der vertikale L-Schenkel ist über Bolzengelenke an den unteren die Walzenlagerungen tragenden Konsolen angelenkt, und der horizontale L-Schenkel weist an seinem Ende ein Verriegelungs-Bolzengelenk auf, nach dessen Entriegelung der L-förmige Schwenkrahmen an den Rahmenenden ausklappbar ist. Dabei liegen allen Bolzen-Gelenkachsen parallel zu den Walzenachsen, so dass die Bolzengelenke unter der vollen Belastung der hohen Walzenpresskräfte stehen. Abgesehen davon, dass es Einbaufälle gibt, bei denen ein Ausklappen des Schwenkrahmens zu den Rahmenenden hin aus Platzgründen nicht möglich ist, kann das Lösen der beanspruchten Verriegelungs-Bolzengelenke, das Betätigen der Bolzen-Gelenkachsen sowie das seitliche Herausziehen einer Walzeneinheit aus dem Maschinenrahmen in einer Richtung quer zum Walzenspalt Aufwand und Schwierigkeiten bereiten.It is known for roller presses (brochure "HRP Hydraulic Roller Press "of the Fuller Corporation of 7/95), part of the machine frame to be designed as an L-shaped swivel frame. The vertical L-leg is the roller bearings via pin joints on the lower supporting consoles, and the horizontal L-leg has a locking pin joint at its end unlocking the L-shaped swing frame at the frame ends can be folded out. All pin-joint axes are parallel to the roller axes so that the pin joints under the full load of the high roller press forces. Except of the fact that there are installation cases in which an unfolding of the Swivel frame towards the frame ends not for space reasons is possible, the loosening of the locking bolt joints claimed, the actuation of the pin-joint axes as well as the lateral one Pull out a roller unit from the machine frame effort and difficulties in a direction transverse to the nip prepare.

Auch aus der Broschüre "Hochdruckzerkleinerung mit Walzenpressen" der Köppern GmbH & Co. KG von 7/87, Seite 6 ist ein als Klapprahmen ausgebildeter Pressenrahmen bekannt, bei dem, um anlässlich eines Walzenwechsels beide Walzen zu den Rahmenenden hin aus dem Maschinenrahmen herausziehen zu können, beide sich gegenüberliegende Schwenkrahmen abgeklappt werden müssen, was einen entsprechenden Platzbedarf zur Folge hat.Also from the brochure "High pressure crushing with roller presses" Köppern GmbH & Co. KG from 7/87, page 6 is a snap frame trained press frame known in order to on the occasion a roll change both rolls towards the frame ends to be able to pull out of the machine frame, both themselves opposite swing frame must be folded down what has a corresponding space requirement.

Der Erfindung liegt die Aufgabe zugrunde, für eine Zweiwalzenmaschine der eingangs genannten Art einen Maschinenrahmen zu schaffen, der eine einfache und schnelle Montage und Demontage der Walzen bei noch dazu geringer Platzbeanspruchung ermöglicht.The invention has for its object for a two-roll machine a machine frame of the type mentioned at the beginning create an easy and quick assembly and disassembly of the rollers with a small space requirement.

Diese Aufgabe wird gemäß der Erfindung mit einer Zweiwalzenmaschine mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.This object is achieved according to the invention with a two-roll machine solved with the features of claim 1. Advantageous configurations the invention are specified in the subclaims.

Charakteristisch für die erfindungsgemäße Zweiwalzenmaschine wie z. B. Rollenpresse zur Gutbettzerkleinerung körnigen Gutes ist, dass der Maschinenrahmen an den Walzenstirnseiten als Schwenkrahmen ausgebildet ist mit einer nicht parallel, sondern senkrecht zu den Walzenachsen liegenden unteren Schwenkachse, so dass nach dem walzenstirnseitigen Wegschwenken der beiden sich gegenüberliegenden Schwenkrahmen beide Walzen samt Lagerböcke als komplette Einheiten aus dem Maschinenrahmen nach oben frei entnehmbar sind. Dabei ist ein Lösen von Bolzengelenken sowie eine seitliche Verschiebung von schweren Walzeneinheiten nicht erforderlich.Characteristic of the two-roll machine according to the invention, such as e.g. B. roller press for comminution of granular good is that the machine frame on the roller ends as a swivel frame is formed with one not parallel, but perpendicular to the Roller axes lying lower pivot axis, so that after the Swiveling away of the two opposite ends on the roll end Swivel frame both rollers together with bearing blocks as a complete Units can be freely removed from the machine frame are. There is a loosening of pin joints as well as a lateral one It is not necessary to move heavy roller units.

Die erfindungsgemäßen zu den Walzenstirnseiten hin abklappbaren Schwenkrahmen weisen jeweils zwei etwa vertikal angeordnete Rahmenseitenteile auf, die mit ihren Unterenden jeweils an die Enden der die Walzenlagerböcke tragenden bzw. führenden Konsolen des Maschinenrahmens angelenkt sind, wobei die Unterenden als auch die Oberenden der Rahmenseitenteile jeweils eines Schwenkrahmens durch je einen Zugstab miteinander verbunden sind. Auf diese Weise sind die abschwenkbaren Schwenkrahmen in sich geschlossen zur Aufnahme der hohen Mahl- bzw. Presskräfte, welche die Funktionsfähigkeit der Schwenkgelenke aber nicht beeinträchtigen. Das heißt, die Gelenke der walzenstirnseitigen Schwenkrahmen werden beim erfindungsgemäßen Maschinenrahmen jedenfalls nicht mit Radialkräften aus dem Mahlvorgang bzw. Pressvorgang belastet.The inventive foldable towards the roller end faces Swing frames each have two approximately vertically arranged frame side parts with their lower ends at the ends of the the bearing brackets of the machine frame that support or guide them are articulated, the lower ends as well as the Upper ends of the frame side parts of a swing frame are connected to each other by a tension rod. In this way the swing-away swivel frames are closed for themselves Absorption of the high grinding or pressing forces, which affect the functionality but do not affect the swivel joints. This means, the joints of the swivel frame at the end of the roller are used for machine frame according to the invention in any case not with radial forces from the milling process or pressing process.

Nach Figur 1 weist die Rollenpresse zur Gutbettzerkleinerung körnigen Gutes einen Maschinenrahmen auf, in dem zwei gegenläufig rotierende Walzen 10, 11 drehbar gelagert sind, die zwischen sich einen Walzenspalt bilden und von denen die Walze 10 als Festwalze und die Walze 11 als Loswalze ausgebildet sind. Die Festwalze 10 stützt sich mit ihren Lagerböcken 12 unmittelbar am Maschinenrahmen ab und liegt auf den Konsolen 14 auf, während die Loswalze 11 mit ihren Lagerböcken 13 auf Gleitbahnen der zwei beabstandeten Konsolen 14 aufliegt und dort mit ihren Lagerböcken quer zum Walzenspalt translatorisch hin- und hergleiten kann. Die Lagerböcke 13 der Loswalze 11 sind gegen flache Hydraulikzylinder 15 abgestützt, mit denen die Walzenpresskraft zur Druckbeanspruchung des im Walzenspalt befindlichen zur zerkleinernden Gutes aufgebracht wird. Die Drehantriebe der beiden Walzen sind in der Zeichnung weggelassen.According to Figure 1, the roller press has granular for material bed comminution Good on a machine frame in which two rotating in opposite directions Rollers 10, 11 are rotatably mounted, one between them Form nip and of which the roller 10 as a fixed roller and the roller 11 are designed as a loose roller. The fixed roller 10 is supported with its pedestals 12 directly on the machine frame and lies on the consoles 14, while the idler roller 11 with their pedestals 13 on slideways of the two spaced Consoles 14 rests and there with their pedestals transversely to the nip can translate back and forth. The pedestals 13 the loose roller 11 are supported against flat hydraulic cylinders 15, with which the roller press force to compress the im Roll nip is applied to the comminuting material. The rotary drives of the two rollers are omitted from the drawing.

Der Maschinenrahmen ist an beiden Walzenstirnseiten jeweils als Schwenkrahmen ausgebildet mit einer senkrecht zu den Walzenachsen liegenden unteren Schwenkachse 16, so dass nach dem walzenstirnseitigen Wegschwenken der beiden sich gegenüberliegenden jeweils in sich geschlossenen Schwenkrahmen beide Walzen 10, 11 samt Lagerböcken 12, 13 aus dem Maschinenrahmen nach oben frei entnehmbar sind, wie aus Figur 3 ersichtlich ist. Dabei weisen die walzenstirnseitigen Schwenkrahmen jeweils zwei etwa vertikal angeordnete Rahmenseitenteile 17, 18 auf, die mit ihren Unterenden jeweils an die Enden der die Walzenlagerböcke 12, 13 tragenden bzw. führenden Konsolen 14 angelenkt sind, wobei die Unterenden als auch die Oberenden der Rahmenseitenteile 17, 18 jeweils eines Schwenkrahmens durch je einen Zugstab 19 bzw. 20 miteinander verbunden sind. Dabei kann der untere Zugstab 19 gleichzeitig die Schwenkachse 16 für die Rahmenseitenteile 17, 18 bilden, so dass dann die Gelenke für die Rahmenseitenteile gleichzeitig axial und radial wirken.The machine frame is on both ends of the roller as Swivel frame designed with a perpendicular to the roller axes lying lower pivot axis 16, so that after the roll end Swinging away the two opposite one another in each case self-contained swivel frame both rollers 10, 11th including pillow blocks 12, 13 up from the machine frame can be removed, as can be seen from Figure 3. The Swivel frames on the roller end each have two approximately vertically arranged Frame side parts 17, 18, each with their lower ends to the ends of the bearing blocks 12, 13 which support or leading consoles 14 are hinged, the lower ends as also the top ends of the frame side parts 17, 18 each one Swivel frame with a pull rod 19 or 20 with each other are connected. The lower tie rod 19 can simultaneously Form pivot axis 16 for the frame side parts 17, 18 so that then the joints for the frame side parts simultaneously axially and radially Act.

Der jeweils in sich geschlossene rechteckige Schwenkrahmen mit den Bauteilen 17, 18, 19, 20 nimmt die Mahlkräfte jeweils sicher auf. Bei der erfindungsgemäßen Rollenpresse wird also durch Abklappung der walzenstirnseitigen Schwenkrahmen die Demontage und Montage beider Walzen samt Lagerböcken ermöglicht.The self-contained rectangular swing frame with The components 17, 18, 19, 20 each reliably absorb the grinding forces. In the roller press according to the invention, this is done by folding the swivel frame on the roller end for disassembly and assembly both rollers and bearing blocks.

Wie aus Figur 1 ersichtlich, trägt der obere Zugstab 20 jeweils eines Schwenkrahmens die obere Walzen-Lagerbockabstützung als Gleitführungen 21, 22, die im eingebauten Zustand der Walzen 10, 11 ausbaubar ist, so dass jedenfalls nach demontierten Gleitführungen 21, 22 das Schwenken der walzenstirnseitigen Schwenkrahmen möglich ist. Durch geeignete Anordnung der Schwenkachse 16 sowie der Gleitführungen 21, 22 ist ein Abklappen der Schwenkrahmen auch ohne vorherige Demontage der Gleitführungen möglich.As can be seen from Figure 1, the upper tie rod 20 carries one each Swing frame the upper roller bearing support as sliding guides 21, 22, the rollers 10, 11 in the installed state can be removed, so that at least after dismantled sliding guides 21, 22 the swiveling of the roll end swivel frame possible is. By suitable arrangement of the pivot axis 16 and the Slideways 21, 22 is also a folding of the swivel frame possible without dismantling the slide guides.

Aus Figur 2 und 3 ist noch ersichtlich, dass an der Innenseite der Rahmenseitenteile 17 etc. des Schwenkrahmens die dort angebrachte Walzenanpressvorrichtung wie z. B. der flache Hydraulikzylinder 15, Messgeräte und dergleichen beim Schwenken der Rahmenseitenteile 17, 18 verbleiben können. Ferner geht aus den Figuren 2 und 3 hervor, dass die beiden sich an den Walzenstirnseiten gegenüberliegenden Schwenkrahmen bzw. deren Rahmenseitenteile 17 an ihren oberen Enden durch parallel zu den Walzenachsen liegende obere Traversen 24 miteinander verbunden sind, die zwecks Ermöglichung des Ausklappens der beiden Schwenkrahmen eine lösbare Verbindungsstelle 25 aufweisen. Die unteren Traversen 23 verbinden die beiden Konsolen 14. So können im Betriebszustand der Rollenpresse die oberen Zugstäbe 20 der Schwenkrahmen bzw. deren Seitenteile 17, 18 über zwei etwa in der Mitte an der lösbaren Verbindung 25 verschraubten Traversenhälften verbunden und ausgerichtet sein.From Figures 2 and 3 it can still be seen that on the inside of the Frame side parts 17 etc. of the swing frame attached there Roller pressing device such. B. the flat hydraulic cylinder 15, measuring devices and the like when pivoting the frame side parts 17, 18 can remain. Also goes from the figures 2 and 3 show that the two are on the end faces of the rollers opposite swing frame or its frame side parts 17 at their upper ends by lying parallel to the roller axes upper trusses 24 are connected to each other for the purpose Allowing the two swivel frames to unfold a detachable one Have connection point 25. Connect the lower cross members 23 the two consoles 14. In the operating state of the Roller press the upper tie rods 20 of the swivel frame or their Side parts 17, 18 about two approximately in the middle of the detachable Connection 25 screwed truss halves connected and aligned his.

Die in Figur 3 schematisch dargestellte Schwenkbewegung der beiden walzenstirnseitigen Schwenkrahmen kann durch eine mechanische und/oder hydraulische Schwenkvorrichtung ausgeführt werden. Die Schwenkarbeit könnte auch mit Einsatz eines vor Ort vorhandenen Kranes realisiert werden. Zur Begrenzung des Schwenkwinkels der Schwenkrahmenteile können Anschläge und auch Sicherungsarretierungen zur Fixierung der Schwenkrahmen in ihrer abgeklappten Endlage vorhanden sein. Jedenfalls braucht der Schwenkwinkel der Schwenkrahmen nur so groß zu sein, dass die Entnahme der beiden Walzeneinheiten noch oben aus dem Maschinenrahmen ermöglicht wird. Der dazu erforderliche Platzbedarf im Gebäude ist vergleichsweise nur sehr gering.The pivoting movement of the two shown schematically in FIG. 3 The swivel frame on the end of the roll can be moved by a mechanical and / or hydraulic swivel device. The swivel work could also be done using an existing one Cranes can be realized. To limit the swivel angle the swing frame parts can stop and also safety locks to fix the swivel frame in its folded down position End position. In any case, the swivel angle needs the Swing frame only to be so big that the removal of the two Roll units still possible from the top of the machine frame becomes. The space required in the building is comparative very little.
