Description

Die Erfindung betrifft einen Maschinenrahmen für eine Hochdruckrollenpresse, der zur Demontage zu öffnen ist.The invention relates to a machine frame for a high-pressure roller press, which is to be opened for disassembly.

Hochdruckwalzenpressen zur Zerkleinerung von Mahlgut wurden erstmals von Schönert et al. in der in der deutschen Offenlegungsschrift DE2708053A1 offenbart. Hochdruckrollenpressen zerkleinern Mahlgut zwischen zwei gegenläufig rotierenden Walzen, die keinen Schlupf zeigen, indem das Mahlgut in einen engen Walzenspalt zwischen den beiden Walzen eingezogen wird. Dort bricht das Mahlgut ohne eine energiezehrende Zerkleinerung durch Scherung, sondern ausschließlich durch Druckbeanspruchung. Die in den Hochdruckwalzenpressen eingesetzten Walzen sind trotz fehlender Scherwirkung einem sehr hohen Verschleiß ausgesetzt, weshalb die Walzen regelmäßig aufgearbeitet oder ausgetauscht werden. Um die Demontage der Hochdruckwalzenpresse beim Ausbau der Walzen zu vereinfachen, wurde in der DE 10 2005 045 273 A1 vorgeschlagen, den Maschinenrahmen so zu konstruieren, dass dieser leicht zu öffnen ist und in welchem die Walzen über gleitend im Maschinenrahmen angeordnete Lagerböcke aus dem Maschinenrahmen herausgeschoben werden können. Bei dieser Konstruktion ist es notwendig, einen Brückenrahmen quer zum Maschinenrahmen vorzusehen, damit die Gurte des Maschinenrahmens nach Ausbau der Walzen mitsamt ihren gleitend angeordneten Lagern nicht durchbiegen oder anfangen, mechanisch zu schwingen und so womöglich Schaden nehmen. Die Gurte werden also durch den Brückenrahmen stabilisiert.High-pressure roller presses for the comminution of regrind were first described by Schönert et al. in the German published patent application DE2708053A1 disclosed. High-pressure roller presses crush grinding stock between two counter-rotating rollers, which do not slip, by drawing the material into a narrow nip between the two rollers. There, the regrind breaks without energy-consuming shredding by shear, but only by compressive stress. The rollers used in the high pressure roller presses are exposed to very high wear despite the lack of shear, which is why the rollers are regularly worked up or replaced. In order to simplify the dismantling of the high - pressure roll press during the removal of the rolls, the DE 10 2005 045 273 A1 proposed to construct the machine frame so that it is easy to open and in which the rollers can be pushed out of the machine frame via bearing blocks arranged in a sliding manner in the machine frame. With this construction, it is necessary to provide a bridge frame across the machine frame, so that the belts of the machine frame do not bend or start to vibrate mechanically after removal of the rollers together with their slidably mounted bearings and thus possibly be damaged. The straps are thus stabilized by the bridge frame.

Dieser an sich erfolgreiche Aufbau hat den Nachteil, dass der Brückenrahmen einen hohen Platzanspruch hat und im Einsatz der Hochdruckrollenpresse fast ohne Funktion ist.This in itself successful construction has the disadvantage that the bridge frame has a high space requirement and is almost without function in use of the high-pressure roller press.

Aufgabe der Erfindung ist es daher, einen Maschinenrahmen für eine Hochdruckrollenpresse vorzuschlagen, für den der Brückenrahmen entbehrlich ist. Die erfindungsgemäße Aufgabe wird gelöst durch einen Maschinenrahmen nach Anspruch 1. Weitere vorteilhafte Ausgestaltungen sind in den Unteransprüchen angegeben.The object of the invention is therefore to propose a machine frame for a high-pressure roller press, for which the bridge frame is dispensable. The object of the invention is achieved by a machine frame according to claim 1. Further advantageous embodiments are specified in the subclaims.

Erfindungsgemäß wird vorgeschlagen, dass gegenüberliegende Gurte im Maschinenrahmen durch eine Seitenwand verbunden sind. Die Seitenwand erfüllt somit mehrere Funktionen. Zum einen dient die Seitenwand als optische Verkleidung, aber auch als Schutz vor seitlich aus dem Mahlraum ausdringendem Mahlgut, das bei den rauen Bedingungen, in denen die Hochdruckwalzenpresse eingesetzt wird, die angrenzenden Lager beschädigen könnte. Neben der optischen Funktion und dem Maschinenschutz hat die Seitenwand aber auch den vorteilhaften Effekt, dass die Gurte im Maschinenrahmen durch die Seitenwand stabilisiert werden. Die Gurte fangen so nicht an, mechanisch zu schwingen, wodurch an Stellen mit einer hohen Knickbelastung Risse entstehen könnten. Des Weiteren können die Gurte auch bei hohen, auf ihnen lagernden Gewichten nicht abbrechen und so die Hochdruckrollenpresse unbrauchbar machen. Die Seitenwand erfüllt somit eine tragende Funktion und macht den Maschinenrahmen zu einem selbsttragenden Chassis für die Mahlwalzen.According to the invention it is proposed that opposite straps are connected in the machine frame by a side wall. The side wall thus fulfills several functions. On the one hand, the side wall serves as an optical cladding, but also as a protection against laterally from the grinding chamber ausdringendem regrind, which could damage the adjacent bearings in the harsh conditions in which the high-pressure roller press is used. In addition to the optical function and the machine protection, the side wall also has the advantageous effect that the straps in the machine frame are stabilized by the side wall. The straps thus do not begin to vibrate mechanically, which could cause cracks in places of high buckling load. Furthermore, the straps can not break even at high, superimposed on them weights and so make the high-pressure roller press unusable. The side wall thus fulfills a supporting function and makes the machine frame a self-supporting chassis for the grinding rollers.

In vorteilhafter Weise ist die Seitenwand etwa U-förmig ausgebildet und das offene Maul der U-Form weist in Richtung der Maschinenrahmenöffnung. Durch diese Bauweise umschließt die Seitenwand die Lager, wobei die Wellen der Mahlwalze aus der Seitenwand herausragen. Dadurch kann die Welle durch die Seitenwand hindurch mit einem Antriebsgetriebe Verbunden werden.Advantageously, the side wall is approximately U-shaped and the open mouth of the U-shape points in the direction of the machine frame opening. By this construction, the side wall encloses the bearings, wherein the waves of the grinding roller protrude from the side wall. Thereby, the shaft can be connected through the side wall with a drive gear.

Da Hochdruckrollen alleine durch die Mahlwalzen ein sehr hohes Gewicht aufweisen, ist man bestrebt, das Gewicht der Hochdruckrollenpressen möglichst gering zu halten. Das geringere Gewicht erleichtert die Logistik der Hochdruckwalzenpressen, da diese in der Regel an unzugänglichen, oder zumindest schlecht erschlossenen Orten stehen, beispielsweise in Minen. Um das Gesamtgewicht der Hochdruckrollenpresse zu verringern, ist vorgesehen, die Seitenwand in Leichtbauweise aufzubauen, wobei einzelne Spanten die Seitenwand versteifen. Die Seitenwand besteht somit aus einem vergleichsweise dünnem Blech, das alleine nicht in der Lage ist, den Kräften zu widerstehen, die an ihr durch eine nicht gestützte Gurtkonstruktion nach Demontage der Hochdruckrollenpresse zerren. Erst die Spanten geben der Seitenwand ihre Stabilität.Since high-pressure rollers alone by the grinding rollers have a very high weight, it is anxious to keep the weight of the high-pressure roller presses as low as possible. The lower weight facilitates the logistics of high pressure roller presses, as these are usually in inaccessible, or at least poorly developed locations, for example, in mines. In order to reduce the overall weight of the high-pressure roller press, it is intended to construct the side wall in lightweight construction, with individual frames stiffening the side wall. The side wall thus consists of a comparatively thin sheet which alone is unable to withstand the forces which tug at it by an unsupported belt construction after disassembly of the high pressure roller press. Only the ribs give the sidewall their stability.

Um die einzelnen Teilelemente des Maschinenrahmens leicht auszugestalten, ist vorgesehen, dass alle Gurte und Teilelemente, sofern sie zur Demontage nicht lösbar miteinander verbunden sein müssen, miteinander verschweißt sind. Dadurch können Schraub- oder Nietlöcher in den Gurten und Teilelementen vermieden werden. Ohne Schraub- und Nietlöcher kann die Materialstärke wiederum herabgesetzt werden, da keine die Stabilität des Maschinenrahmens schwächende Löcher vorhanden sind. Sofern die Teilelemente miteinander verschraubt werden, müsste die Materialstärke zur Vermeidung von Bruchstellen angepasst werden.In order to design the individual sub-elements of the machine frame easily, it is provided that all straps and sub-elements, if they are not detachably connected to each other for disassembly, are welded together. As a result, screw or rivet holes can be avoided in the straps and sub-elements. Without screw and rivet holes, the material thickness can be reduced again, since there are no weakening the stability of the machine frame holes. If the sub-elements are bolted together, the material thickness would have to be adjusted to avoid breakages.

The invention will be explained in more detail with reference to the following figures. It shows:
FIG. 1
a high-pressure roller press with machine frame according to the invention
FIG. 2
a machine frame according to the invention in partial view,
FIG. 3
an isolated side view.

In Figur 1 ist eine Hochdruckrollenpresse 100 abgebildet, die einen erfindungsgemäßen Maschinenrahmen 110 aufweist. In dem Maschinenrahmen 110 sind Lagerböcke 111, 112, 113 und (nicht sichtbar) 114 aufgenommen, die auf Konsolen gleiten, von denen in dieser Ansicht nur die vordere Konsole 115 sichtbar ist. In den Lagerböcken sind korrespondierende Lager aufgenommen, welche die Wellen 120 und 130 der Mahlwalzen 121 und 131 drehbar lagern.In FIG. 1 a high-pressure roller press 100 is shown, which has a machine frame 110 according to the invention. In the machine frame 110 bearing blocks 111, 112, 113 and (not visible) 114 are recorded, which slide on consoles, of which only the front console 115 is visible in this view. In the bearing blocks corresponding bearings are added, which support the shafts 120 and 130 of the grinding rollers 121 and 131 rotatably.

Um die Mahlwalzen 121 und 131 aus dem Maschinenrahmen 110 auszubauen, ist in dieser Ausgestaltung vorgesehen, einen Überwurf 140 vom Maschinenrahmen 110 abzuheben, um so den Maschinenrahmen auf der von der papierebene nach hinten weisenden Seite des Maschinenrahmens zu öffnen. Die Mahlwalzen 121 und 131 werden sodann mitsamt ihrer Lager und den Lagerböcken 111, 112, 113 und 114 in Bezug auf die Papierebene nach hinten aus dem Maschinenrahmen herausgeschoben. Die Teilelemente oder Gurtkonstruktionen 150 und 151 bleiben nach der Demontage der Mahlwalzen zurück und bilden ein offenes Maul. Damit der Maschinenrahmen nicht unter seiner eigenen Last deformiert oder in mechanisches Schwingen gerät, ist erfindungsgemäß vorgesehen, dass eine Seitenwand 160 die beiden Gurtkonstruktionen 150 auf der Oberseite und Gurtkonstruktion 151 auf der Unterseite gegeneinander abstützt.In order to remove the grinding rollers 121 and 131 from the machine frame 110, it is provided in this embodiment to lift a shroud 140 from the machine frame 110 so as to open the machine frame on the paper plane backward side of the machine frame. The grinding rollers 121 and 131 are then pushed out of the machine frame together with their bearings and the bearing blocks 111, 112, 113 and 114 with respect to the plane of the paper to the rear. The sub-elements or belt constructions 150 and 151 remain behind after disassembly of the grinding rollers and form an open mouth. So that the machine frame is not deformed under its own load or comes into mechanical swinging, the invention provides that a side wall 160 supports the two belt structures 150 on the top and belt construction 151 on the underside against each other.

Um die Seitenwand besser erkennen zu können, ist in Figur 2 der Maschinenrahmen 110 in perspektivischer Ansicht und durchgeschnitten dargestellt. Deutlich ist zwischen den hinteren Teilen der oberen Gurtkonstruktion 150 und der unteren Gurtkonstruktion 151 die Seitenwand 160 zu erkennen, welche die Gurtkonstruktionen 150 und 151 davor schützt, unter der eigenen Last Schaden zu nehmen oder in mechanische Schwingung zu geraten, wodurch der Maschinenrahmen an Stellen mit einer starken Knickbelastung brechen könnte.To better recognize the side wall is in FIG. 2 the machine frame 110 shown in a perspective view and cut through. It is clearly seen between the rear parts of the upper belt structure 150 and the lower belt construction 151, the side wall 160, which protects the belt structures 150 and 151 from being damaged or mechanically vibrated under its own load, whereby the machine frame in places with could break a strong buckling load.

Die Seitenwand 160 ist aus einem so dünnen Blech hergestellt, dass es alleine nicht dazu in der Lage wäre, die Kräfte, die nach Demontage der Mahlwalzen auf das Blech wirken würden, aufzunehmen. Daher ist die Seitenwand mit Spanten 161 verstärkt. Die Seitenwand 160 selbst ist nicht eben, sondern weist eine dreidimensionale Struktur auf, so dass sie möglichst Verwindungssteif aufgebaut ist. Durch den extremen Leichtbau ist der Maschinenrahmen 110 gegenüber konventionellen Maschinenrahmen wesentlich leichter, so dass dieser leichter transportiert werden kann.The side wall 160 is made of such a thin sheet that it alone would not be able to absorb the forces after disassembly of the grinding rolls the sheet would act to take up. Therefore, the side wall is reinforced with ribs 161. The side wall 160 itself is not flat, but has a three-dimensional structure, so that it is constructed torsionally stiff as possible. Due to the extreme lightweight construction of the machine frame 110 is compared to conventional machine frame much lighter, so that it can be easily transported.

Um die Struktur der Seitenwand 160 besser erkennen zu können, ist diese in Figur 3 isoliert dargestellt. Deutlich ist zu erkennen, dass die Seitenwand 160 aufgrund ihrer U-Form ein offenes Maul 165 aufweist, das zur Aufnahme der aus dem Maschinenrahmen herausragenden Wellen 120 und 130 in die Seitenwand 160 eingebracht ist. Die Seitenwand weist eine dreidimensionale Struktur auf, die ihr durch die Formgebung der Seitenwand selbst und durch die Spanten 161 verliehen wird. Diese dreidimensionale Struktur verleiht der Seitenwand so viel Verwindungssteifheit, dass diese die Kräfte der Gurtkonstruktionen 150 und 151 aufnehmen kann, ohne selbst dabei zu deformieren. Dadurch kann eine Brückenkonstruktion vermieden werden, welche die Gurtkonstruktionen 150 und 151 nach Ausbau der Mahlwalzen 121 und 131 mitsamt den Wellen 120 und 130 sowie den vier Lagerböcken 111, 112, 113 und 114 halten und stabilisieren soll. BEZUGSZEICHENLISTE 100 Hochdruckrollenpresse 131 Mahlwalze 110 Maschinenrahmen 111 Lagerbock 140 Überwurf 112 Lagerbock 113 Lagerbock 150 Gurtkonstruktion 114 Lagerbock 151 Gurtkonstruktion 115 Konsole 160 Seitenwand 120 Welle 161 Spanten 121 Mahlwalze 165 Maul 130 Welle In order to better recognize the structure of the side wall 160, this is shown isolated in Figure 3. It can be clearly seen that the side wall 160 has an open mouth 165 due to its U-shape, which is inserted into the side wall 160 for receiving the shafts 120 and 130 protruding from the machine frame. The sidewall has a three-dimensional structure imparted to it by the shape of the sidewall itself and by the ribs 161. This three-dimensional structure gives the sidewall so much torsional stiffness that it can absorb the forces of the belt constructions 150 and 151 without itself deforming. Thereby, a bridge construction can be avoided, which is to hold and stabilize the belt constructions 150 and 151 after removal of the grinding rollers 121 and 131 together with the shafts 120 and 130 and the four bearing blocks 111, 112, 113 and 114. <I> LIST OF REFERENCES </ i> 100 High-pressure roller press 131 grinding roll 110 machine frame 111 bearing block 140 wrap 112 bearing block 113 bearing block 150 belt construction 114 bearing block 151 belt construction 115 console 160 Side wall 120 wave 161 ribs 121 grinding roll 165 mouth 130 wave
