Abstract

In order to create a roller press, particularly for comminuting a bed of material, the roller press having two rollers separated from each other by a roller nip and using hydraulic cylinders to press the one roller against the oppositely situated roller over the material situated in the roller nip, the stress on the surface of the rollers to be reduced and their service life to be increased, it is proposed according to the invention that both rollers are designed as loose rollers that are displaceable transversely relative to the roller nip, the bearing housings of the rollers being supported on side parts of the machine frame by hydraulic cylinders that apply the roller compaction pressure.

Description

Die Erfindung betrifft eine Rollenpresse zur Druckbehandlung insbesondere zur Gutbettzerkleinerung oder Kompaktierung bzw. Brikettierung körnigen Gutes, mit zwei in Lagergehäusen drehbar gelagerten gegenläufig angetriebenen und durch einen Walzenspalt voneinander getrennten Walzen, wobei die Lagergehäuse mit Ihren Unter- und Oberseiten auf Gleitbahnen von Konsolen des Maschinenrahmens gelagert sind, mit Einsatz von Hydraulikzylindern zum Anpressen der einen Walze über das im Walzenspalt befindliche Gut gegen die gegenüberliegende Walze.The invention relates to a roller press for pressure treatment in particular for Gutbettzerkleinerung or compaction or briquetting granular material, with two rotatably mounted in bearing housings counter-driven and separated by a nip rollers, the bearing housing stored with your lower and upper sides on slides of consoles of the machine frame are, with the use of hydraulic cylinders for pressing the one roller over the material located in the nip against the opposite roller.

Bei Walzenmühlen zur Durchführung der sogenannten Gutbettzerkleinerung werden die einzelnen Stücke bzw. Partikel des durch Reibung in den Walzenspalt eingezogenen Mahlgutes wie z. B. Zementrohmaterial, Zementklinker, Erze oder dergleichen in einem Gutbett, d. h. in einer zwischen den beiden Walzenoberflächen zusammengedrückten Materialschüttung bei Anwendung eines hohen Druckes gepresst und gegenseitig zerkleinert, wobei man statt von einer Walzenmühle auch von einer Walzenpresse oder Rollenpresse spricht. Bei solchen bekannten Rollenpressen, siehe z. B. Broschüre "Rollenpressen" Nr. 2-300d der KHD Humboldt Wedag AG vom September 1994 oder z. B. WO 2005/070549 A1 , ist eine der beiden Walzen als Festwalze ausgebildet, die sich über Ihre Lagergehäuse gegen Endstücke des Maschinenrahmens abstützt, während sich die andere Walze als Loswalze über deren Lagergehäuse an Hydraulikzylindern abstützt, mit denen die Walzenpresskraft aufgebracht wird.In roll mills for performing the so-called Gutbettzerkleinerung the individual pieces or particles of the drawn by friction in the nip grinding material such. B. cement raw material, cement clinker, ores or the like in a bed of material, ie pressed in a compressed between the two roll surfaces bulk material when using a high pressure and crushed each other, wherein instead of a roll mill also speaks of a roll press or roller press. In such known roller presses, see, for. B. brochure "roller presses" No. 2-300d of KHD Humboldt Wedag AG from September 1994 or z. B. WO 2005/070549 A1 , One of the two rollers is designed as a fixed roller, which is supported via their bearing housing against end pieces of the machine frame, while the other roller is supported as a Loswalze on the bearing housing to hydraulic cylinders, with which the roller pressing force is applied.

Beim Betrieb derartiger Rollenpressen sind die Oberflächen der Walzen aufgrund der hohen Pressdrücke und Presskräfte einer hohen Verschleißbeanspruchung ausgesetzt, besonders dann, wenn die Loswalze je nach Gutmaterialzufuhr zum Walzenspalt seitliche Ausweichbewegungen macht, wobei sich dann aufgrund der feststehenden Festwalze auch die Mittellage des Walzenspaltes und der aus diesem unten austretenden gepressten Gutmaterialschülpe ändert. Die Ausweichbewegung der Loswalze ist besonders dann groß, stoßartig und für den Oberflächenverschleiß der Walzen sowie für den Betrieb der Rollenpresse abträglich, wenn in den Walzenspalt ein unzerkleinerbarer Fremdkörper, z. B. ein verlorener Hammer eines vorgeschalteten Hammerbrechers gerät.In the operation of such roller presses, the surfaces of the rollers are exposed to high wear stress due to the high compression pressures and compressive forces, especially when the Loswalze makes depending on Gutmaterialzufuhr to the nip lateral evasive movements, which then due to the fixed fixed roller and the center position of the nip and this pressed out Gutgutschülpe exiting below changes. The evasive movement of the Loswalze is particularly large, jerky and detrimental to the surface wear of the rollers and for the operation of the roller press when in the nip an unzerkleinerbarer foreign body, eg. B. a lost hammer of an upstream hammer crusher device.

Aus der DE 19 27 164 C3 ist eine Doppelschwingenwalzenmühle bekannt, bei der die beiden Walzen jeweils in Schwingenarmen gelagert sind, die mit ihren unteren Enden am Maschinenrahmen angelenkt sind, so dass beide Walzen Ausweichwalzen sind. Jedoch ist das Prinzip der Doppelschwingenwalzenmühle bisher nur für Walzenmühlen realisiert worden, nicht für Gutbettzerkleinerungs-Rollenpressen, bei denen die Walzenpresskräfte etwa um eine Zehnerpotenz höher liegen müssen als bei Walzenmühlen, z. B. bei 8 t/cm Walzenlänge und höher. Infolge der vergleichsweise niedrigen Walzendrücke und Walzenpresskräfte treten bei Walzenmühlen gravierende Probleme eines Walzenoberflächenverschleißes nicht auf. Abgesehen von der enormen Gewichtsbelastung durch die schwergewichtigen Walzen belastet eine stoßartige Änderung der Walzenspaltweite z. B. anlässlich eines Fremdkörperdurchganges bei der Doppelschwingenwalzenmühle zusätzlich die Schwingenlagerungsgelenke, die daher besonders massiv und schwergewichtig ausgeführt sein müssen.From the DE 19 27 164 C3 is a double swing roller mill is known in which the two rollers are each mounted in swing arms, which are hinged at their lower ends on the machine frame, so that both rollers are Ausweichwalzen. However, the principle of Doppelschwingenwalzenmühle has been realized only for roll mills, not for Gutbettzerkleinerungs roller presses, where the roller press forces must be about one order of magnitude higher than roller mills, z. B. at 8 t / cm roll length and higher. Due to the comparatively low roller pressures and roller press forces, serious problems of roller surface wear do not occur in roller mills. Apart from the enormous weight load by the heavyweight rollers loaded a jerky change in the nip width z. B. on the occasion of a foreign body passage in the double rocker roller mill in addition the swing bearing joints, which must therefore be made particularly solid and heavyweight.

Der Erfindung liegt die Aufgabe zugrunde, eine Rollenpresse insbesondere zur Gutbettzerkleinerung zu schaffen, mit einem an sich konventionellen Maschinenrahmen mit Konsolen-Gleitbahnen zur Auflagerung der Walzen-Lagergehäuse, wobei aufgrund der Maschinenkonstruktion die Oberflächenbeanspruchung der Walzen vermindert und die Walzenstandzeit erhöht sind.The invention has for its object to provide a roller press in particular for Gutbettzerkleinerung, with a per se conventional machine frame with console slideways for bearing the roller bearing housing, which reduces due to the machine design, the surface stress of the rollers and the roller life are increased.

Diese Aufgabe wird gemäß der Erfindung mit einer Rollenpresse 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 roller press with the features of claim 1. Advantageous embodiments of the invention are specified in the subclaims.

Bei der erfindungsgemäßen Rollenpresse ist nicht wie bisher üblich die eine Walze als Festwalze über ihre Lagergehäuse starr an Seitenteilen des Maschinenrahmens abgestützt, während die andere Walze als Loswalze über ein Hydrauliksystem federnd ausweichbar abgestützt ist, sondern erfindungsgemäß sind beide Walzen als quer zum Walzenspalt bewegliche Loswalzen ausgebildet, deren Lagergehäuse über den Walzenpressdruck aufzubringende Hydraulikzylinder an Seitenteilen des Maschinenrahmens abgestützt sind. Das heißt, bei der erfindungsgemäßen Rollenpresse ist die Losrollenseitenhälfte in der Maschinenmitte praktisch komplett gespiegelt. Bei dieser Maschinenkonstruktion weichen beide Loswalzen bei sich ändernder Pressschülpendicke und z. B. bei einem Fremdkörperdurchgang durch den Walzenspalt immer spiegelsymmetrisch zum ursprünglichen Walzenspalt aus. Die Walzenausweichbewegungen und Wege und die dabei auftretenden Beschleunigungen sowie auch evtl. auftretende Walzenschiefstellungen vermindern sich pro Loswalze im Vergleich zum konventionellen Rollenpressensystem bis zur Hälfte.In the roller press according to the invention is not as previously customary one roller supported as a fixed roller on its bearing housing rigidly on side parts of the machine frame, while the other roller is resiliently supported as Losdreze via a hydraulic system, but according to the invention both rollers are designed as transverse to the nip movable Loswalzen whose bearing housings are to be applied via the roll pressure hydraulic cylinder to be applied to side parts of the machine frame. That is, in the roller press according to the invention, the Losrollenseitenhälfte is almost completely mirrored in the middle of the machine. In this machine design both Loswalzen soft with changing squish thickness and z. B. in a foreign body passage through the nip always mirror symmetry to the original nip. The roller evasive movements and paths and the accelerations occurring as well as any occurring roll misalignments are reduced by up to half per loose roller compared to the conventional roller press system.

Überraschend hat sich gezeigt, dass daraus bei der erfindungsgemäßen Rollenpresse eine geringere Verschleißbeanspruchung der Walzenoberfläche, d. h. eine erhöhte Standzeit der Walzen beim Walzenpressenbetrieb resultiert.Surprisingly, it has been shown that with the roller press according to the invention a lower wear stress of the roll surface, ie an increased service life of the rollers results in roller press operation.

Um bei der erfindungsgemäßen Rollenpresse die Ausweichbewegungen der beiden Loswalzen nicht zu behindern, sollen die Reibungskräfte zwischen den Lagergehäusen und den Gleitbahnen der Maschinenkonsolen so gering wie möglich sein.In order not to hinder the evasive movements of the two idler rolls in the roller press according to the invention, the frictional forces between the bearing housings and the slides of the machine consoles should be as low as possible.

Nach einem weiteren Merkmal der Erfindung sind sämtliche Hydraulikzylinder der beiden Loswalzen so mit Drucköl beaufschlagt, dass sich beide Loswalzen gleichmäßig symmetrisch zur Maschinenmitte hin spiegelbildlich zu dieser bewegen. Dazu können die Druckölräume sämtlicher Hydraulikzylinder über einen Ölvolumenstromteiler mit einem Stickstoffgasspeicher so verbunden sein, dass beide Loswalzen zum Walzenspalt hin zentriert sind. Es besteht aber auch die Möglichkeit, die Lageänderung der beiden Loswalzen zu messen und über die Messwerte der Loswalzenpositionen die Druckölbeaufschlagung der einzelnen Hydraulikzylinder nachzuregeln.According to a further feature of the invention, all the hydraulic cylinders of the two Loswalzenzen so pressurized oil, that both Loswalzen evenly symmetrical to the machine center in mirror image to move to this. For this purpose, the pressure oil chambers of all hydraulic cylinders can be connected via an oil volume flow divider with a nitrogen gas storage so that both Loswalzen are centered towards the nip. But it is also possible to measure the change in position of the two Loswalzenzen and readjust the Druckölbeaufschlagung the individual hydraulic cylinders via the measured values of the Loswalzenpositionen.

Bei der erfindungsgemäßen Rollenpresse kann der Walzenwechsel vereinfacht werden, wenn wenigstens eines der beiden Seitenteile am Maschinenrahmen angelenkt und zum Walzenwechsel zur Seite hin ausklappbar ist. Dann können die Hydraulikzylinder mit Vorteil so an dem jeweiligen ausklappbaren Seitenteil des Maschinenrahmens befestigt sein, dass die jeweilige Walze samt Lagergehäusen über die ausgeklappten Hydraulikzylinder hinweg über das Seitenteil aus- und einbaubar ist.In the roller press according to the invention, the roll change can be simplified if at least one of the two side parts articulated on the machine frame and the roll change to the side is folded out. Then, the hydraulic cylinder can be advantageously attached to the respective fold-out side part of the machine frame, that the respective roller including bearing housings on the unfolded hydraulic cylinder away on the side part off and can be installed.

Die Erfindung und deren weitere Merkmale und Vorteile werden anhand der in den Figuren schematisch dargestellten Ausführungsbeispiele näher erläutert.The invention and its further features and advantages will be explained in more detail with reference to the embodiments schematically illustrated in the figures.

Alle drei Ausführungsbeispiele der erfindungsgemäßen Rollenpresse weisen einen in sich geschlossenen Maschinenrahmen zur Aufnahme der hohen Walzenpresskräfte auf. Bei allen Ausführungsbeispielen sind beide Walzen, also sowohl die linke Walze 10 als auch die rechte Walze 11 als quer zum Walzenspalt 12 bewegliche Loswalzen ausgebildet, deren Lagergehäuse 13, 14 über den Walzenpressdruck aufbringende Hydraulikzylinder 15, 16 an Seitenteilen 17, 18 des Maschinenrahmens abgestützt sind. Alle Lagergehäuse 13, 14 sind mit ihren Unter- und Oberseiten auf den Gleitbahnen der unteren und oberen Konsolen 19 und 20 des Maschinenrahmens gelagert. Die übrigen notwendigen Maschinenbauteile wie der Gutaufgabeschacht etc. sind in der Zeichnung weggelassen.All three embodiments of the roller press according to the invention have a self-contained machine frame for receiving the high roller pressing forces. In all embodiments, both rollers, so both the left roller 10 and the right roller 11 are formed as transverse to the nip roller 12 movable Loswalzen whose bearing housing 13, 14 on the roll pressure applying hydraulic cylinders 15, 16 are supported on side parts 17, 18 of the machine frame , All bearing housings 13, 14 are mounted with their lower and upper sides on the slides of the lower and upper brackets 19 and 20 of the machine frame. The remaining necessary machine components such as the Gutaufgabeschacht etc. are omitted in the drawing.

Bei allen drei Ausführungsbeispielen der erfindungsgemäßen Rollenpresse sind die jeweiligen Losrollenseitenhälften in der Maschinenmitte, d. h. zum örtlich zentral bleibenden Walzenspalt 12 praktisch komplett symmetrisch gespiegelt, so dass beide Walzen 10, 11 zur Seite hin symmetrisch ausweichbare Walzen sind, wodurch sich die oben genannten geringeren Walzenoberflächenbeanspruchungen ergeben. Dies ist besonders vorteilhaft beim Einsatz der erfindungsgemäßen Rollenpresse zur Gutbettzerkleinerung abrasiver Gutmaterialien wie Erze, Zementklinker oder dergleichen, die einen hohen Verschleiß an den Walzenoberflächen verursachen.In all three embodiments of the roller press according to the invention, the respective idler side halves in the machine center, ie mirrored to spatially central nip 12 practically completely symmetrical, so that both rollers 10, 11 to the side symmetrically evasive rolls, resulting in the above-mentioned lower roll surface stresses , This is particularly advantageous when using the inventive Roller press for Gutbettzerkleinerung of abrasive good materials such as ores, cement clinker or the like, which cause high wear on the roll surfaces.

Sollte dennoch ein Auswechseln der Walzen erforderlich sein, so kann dies z. B. dadurch vereinfacht werden, wenn wenigstens eines der beiden Seitenteile des Maschinenrahmens am Rahmen angelenkt und zum Walzenwechsel zur Seite hin ausklappbar ist, so dass dann über die ausgeklappten Seitenteile die Walzen zur Seite herausgezogen werden können. So kann nach Fig. 2 das an der linken Maschinenseite gelegene Seitenteil als Klapprahmen 21 über das Gelenk 22 zur Seite ausgeklappt werden. Nach dem Ausführungsbeispiel der Fig. 3 kann zusätzlich dazu auch noch das an der rechten Maschinenseite gelegene Seitenteil 23 über das Gelenk 24 als Klapprahmen zur Seite ausgeklappt werden, um einen noch bequemeren Montagezugang zu beiden Walzen zu erhalten.Should it still be necessary to replace the rollers, this can be done, for. B. be simplified if at least one of the two side parts of the machine frame hinged to the frame and the roll change to the side is folded out, so that then can be pulled over the unfolded side panels, the rollers to the side. So can after Fig. 2 located on the left side of the machine side part as a folding frame 21 via the joint 22 are unfolded to the side. According to the embodiment of Fig. 3 In addition, also located on the right side of the machine side part 23 can be folded over the hinge 24 as a folding frame to the side in order to obtain an even more convenient mounting access to both rollers.
