Description

Die Erfindung betrifft ein Hochdruckgefäß zur Behandlung von Schüttgut insbesondere Hackschnitzel, bestehend aus einem zylindrischen Mantel mit Deckel und Kolben, die relativ zueinander beweglich sind, sowie mit einer oberen Siebplatte beim Deckel und einer unteren Siebplatte beim Kolben, zu welchen zumindest je eine Bohrung zum Zu- und Ableiten von Behandlungsmedien für das Schüttgut führt.The invention relates to a high-pressure vessel for the treatment of bulk material, in particular wood chips, consisting of a cylindrical jacket with a lid and piston, which are movable relative to one another, and with an upper sieve plate for the lid and a lower sieve plate for the piston, to which at least one bore for closing - and deriving treatment media for the bulk material leads.

In der AT-PS 375 561 wird eine Filterpresse zur Herstellung von Zellstoff beschrieben, die aus einem Mantel und zwei in diesen eintau­chenden und den Behandlungsraum begrenzende Kolben besteht, wobei sowohl die Kolben zueinander als auch der Mantel zu den Kolben relativ beweglich sind. Im Abstand von jedem Kolbenboden ist jeweils eine Siebplatte angeordnet, zu der über eine Bohrung Behandlungsmedien zu­und abgeleitet werden. Zur Beschickung wird der obere Kolben ausgefahren und zur Austragung wird der Mantel vom unteren Kolben ab­gehoben.AT-PS 375 561 describes a filter press for the production of cellulose, which consists of a jacket and two pistons immersing in it and delimiting the treatment space, both the piston relative to one another and the jacket relative to the piston being relatively movable. A screen plate is arranged at a distance from each piston crown, to which treatment media are fed in and out via a bore. The upper piston is extended for loading and the jacket is removed from the lower piston for discharge.

Für eine optimale Ausnutzung des Volumens des Behandlungsraums ist es zweckmäßig, das eingebrachte Schüttgut, z.B. Hackschnitzel, vorzuverdichten. Dies geschieht in der oben beschriebenen Anordnung mit Hilfe des oberen Kolbens.For optimal use of the volume of the treatment room, it is advisable to use the bulk material, e.g. Wood chips to pre-compact. This is done in the arrangement described above with the help of the upper piston.

Aufgabe der Erfindung ist die Schaffung einer neuen Stampfeinrichtung zur Vorverdichtung des Schüttguts im Hochdruckgefäß, wobei vor allem die Bauhöhe, sowie der Energie- und Bauaufwand verringert werden sollen.The object of the invention is to create a new ramming device for pre-compressing the bulk material in the high-pressure vessel, in particular the overall height and the energy and construction costs to be reduced.

Dies wird bei einem Hochdruckgefäß der eingangs genannten Art erfin­dungsgemäß dadurch erreicht, daß zur Vorverdichtung des Schüttguts unterhalb des Deckels eine senk- und hebbare Stampfplatte angeordnet ist, welche die obere Siebplatte trägt.This is achieved according to the invention in a high-pressure vessel of the type mentioned at the outset in that, for the pre-compression of the bulk material, a lowerable and lifting ramming plate is arranged below the lid and carries the upper sieve plate.

Weitere Merkmale und Einzelheiten der Erfindung werden nachfolgend anhand der Zeichnung erläutert. Es zeigen

  • Fig. 1 ein erstes Ausführungs beispiel in Form einer Oberkolbenpresse mit einer erfindungsgemäßen Stampfeinrichtung, und
  • Fig. 2 ein zweites Ausführungsbeispiel in Form einer Unterkolbenpresse.
Further features and details of the invention are explained below with reference to the drawing. Show it
  • Fig. 1 shows a first embodiment example in the form of an upper piston press with a ramming device according to the invention, and
  • Fig. 2 shows a second embodiment in the form of a lower piston press.

In Fig. 1 bezeichnet 1 den Mantel des Aufschlußgefäßes einer Oberkolbenpresse, der mit zwei oder mehreren Armen 2 versehen ist, deren jeder mit einer Stange 3 eines Ausstoßzylinders 4 verbunden ist, der am Fundament verankert ist. Der mit der Stange 3 verbundene Kolben 5 kann durch entsprechende Beaufschlagung des Zylinders 4 mit Drucköl gehoben und gesenkt werden, wodurch auch der Mantel 1 gehoben und gesenkt wird. An der Unterseite des Mantels 1 ist ein Flanschring 6 mit innenliegender Dichtung 7 angeschraubt, die an der Wandung eines Kolbens 8 anliegt, der im Fundament verankert ist und in den Mantel 1 eintaucht. Die obere Öffnung des Mantels 1 wird durch einen Deckel 9 abgeschlossen, der ebenfalls eine Dichtung 10 aufweist, die an der abgestuften Innenwandung größeren Durchmessers am oberen Rand des Mantels 1 anliegt. Der Deckel 9 setzt sich nach oben als Kolbenstange 11 mit Kolben 12 fort, der in einem Hauptzylinder 13 verschiebbar ist. Innerhalb der Kolbenstange 11 ist ein Hohlzylinder 14 vorgesehen, in der ein weiterer Kolben 15 verschiebbar ist, der über eine Kolben­stange 16 mit einer Stampfplatte 17 in einer Vertiefung auf der Unter­seite des Deckels 9 verbunden ist.In Fig. 1, 1 denotes the jacket of the digestion vessel of an upper piston press, which is provided with two or more arms 2, each of which is connected to a rod 3 of an ejection cylinder 4, which is anchored to the foundation. The piston 5 connected to the rod 3 can be raised and lowered by correspondingly applying pressure to the cylinder 4, whereby the jacket 1 is also raised and lowered. On the underside of the jacket 1, a flange ring 6 with an internal seal 7 is screwed, which bears against the wall of a piston 8, which is anchored in the foundation and dips into the jacket 1. The upper opening of the jacket 1 is closed by a cover 9, which also has a seal 10, which is on the stepped inner wall of larger diameter at the top of the Coat 1 is applied. The lid 9 continues upwards as a piston rod 11 with a piston 12 which is displaceable in a master cylinder 13. A hollow cylinder 14 is provided within the piston rod 11, in which a further piston 15 is displaceable and is connected via a piston rod 16 to a ramming plate 17 in a recess on the underside of the cover 9.

Zur Sicherung der Stampfplatte 17 gegen Verdrehung um die Mittelachse der Kolbenstange 16 ist im Kolben 15 eine Bohrung 18 vorhanden, die auf einer starr gelagerten Führungsstange 19 gleitet.To secure the ramming plate 17 against rotation about the central axis of the piston rod 16, there is a bore 18 in the piston 15 which slides on a rigidly mounted guide rod 19.

Im Übergangsbereich zwischen der Kolbenstange 11 und dem Deckel 9 ist eine Dichtung 20 für die Kolbenstange 16 vorgesehen. Zur Beaufschlagung des Kolbens 15 im Hohlzylinder 14 sind Bohrungen 21 und 22 in der Kolbenstange 11 vorhanden, die in Bohrungen 23,24 im Deckel 9 übergehen und als Druckölzuführungen 25,26 enden, zu welchen Schlauch­leitungen (nicht dargestellt) führen. In einer Ausnehmung auf der Unterseite der Stampfplatte 17 ist im Abstand zum Plattenboden eine Siebplatte 27 angebracht, die eine Vielzahl kleinerer Bohrungen 28 aufweist und durch Leisten od.dgl. Versteifungen (nicht dargestellt) am Plattenboden abgestützt sein kann. Über Bohrungen 29 im Deckel 9 und in der Stampfplatte 17 können Behandlungsmedien in den Verteiler- und Sammelraum 30 zwischen Siebplatte 25 und dem Boden der Stampfplat­te 17 geleitet bzw. aus diesem abgeleitet werden. Über Bohrungen 31 in der Stampfplatte 17 und in der Siebplatte 27 ragen mehrere Temperatur­fühler 32 vom Boden des Deckels 9 ausgehend in den Behandlungsraum hinein.A seal 20 for the piston rod 16 is provided in the transition region between the piston rod 11 and the cover 9. To act on the piston 15 in the hollow cylinder 14 there are bores 21 and 22 in the piston rod 11 which merge into bores 23, 24 in the cover 9 and end as pressure oil feeds 25, 26 to which hose lines (not shown) lead. In a recess on the underside of the ramming plate 17, a sieve plate 27 is attached at a distance from the plate bottom, which has a plurality of smaller bores 28 and the like by strips. Stiffeners (not shown) can be supported on the plate bottom. Treatment media can be conducted into or diverted from the bores 29 in the cover 9 and in the ramming plate 17 into the distribution and collection space 30 between the sieve plate 25 and the bottom of the ramming plate 17. A plurality of temperature sensors 32 protrude from the bottom of the cover 9 into the treatment room via bores 31 in the ramming plate 17 and in the sieve plate 27.

In einer Ausnehmung auf der Oberseite des Kolbens 8 ist im Abstand zum Kolbenboden ebenfalls eine Siebplatte 27 mit einer Vielzahl von Bohrungen 28 angebracht. Über Leitungen 33 und Bohrungen 34 im Kolben 8 können Behandlungsmedien in den Verteiler- und Sammelraum 30 zwischen Siebplatte 27 und dem Boden des Kolbens 8 zu - bzw. aus diesem abgeleitet werden.In a recess on the top of the piston 8, a screen plate 27 with a plurality of bores 28 is also arranged at a distance from the piston head. Treatment media can be fed into or out of the distribution and collection space 30 between the sieve plate 27 and the bottom of the piston 8 via lines 33 and bores 34 in the piston 8.

Zum Beschicken und Austragen wird der Deckel 9 durch den Kolben 12 des Hauptzylinders 13 geöffnet. Zum Vorkomprimieren des Schüttguts wird der Deckel 9 geschlossen und die Stampfplatte 17 gesenkt und gehoben, wobei dazu nur ca. 10% der Preßkraft des Hauptzylinders 13 erforderlich ist. Wenn der Hauptzylinder 13 mit voller Kraft arbeitet, stützt sich die Stampfplatte 17 an der Unterseite des Deckels 9 ab. Da der Durchmesser der Stampfplatte 17 nur etwas kleiner als der Innendurchmesser des Mantels 1 sein darf, entsteht durch die Durch­messerdifferenz der unteren Dichtung 7 und der oberen Dichtung 10 bei Beaufschlagung mit Druck eine auf den Mantel 1 nach unten wirkende Kraft, die durch die Kolben 5 der Zylinder 4 kompensiert wird. Ein separater Schließzylinder oder eine mechanische Verriegelung für den Deckel 9 ist nicht erforderlich.For charging and discharging, the cover 9 is opened by the piston 12 of the master cylinder 13. To pre-compress the bulk material, the lid 9 is closed and the ramming plate 17 is lowered and raised, only about 10% of the pressing force of the master cylinder 13 being required for this. When the master cylinder 13 works at full power, the ramming plate 17 is supported on the underside of the cover 9. Since the diameter of the ramming plate 17 may only be slightly smaller than the inside diameter of the casing 1, the difference in diameter between the lower seal 7 and the upper seal 10, when pressurized, creates a downward force on the casing 1, which is caused by the pistons 5 the cylinder 4 is compensated. A separate locking cylinder or a mechanical lock for the cover 9 is not required.

Die für das Behandlungsverfahren notwendigen Volumensveränderungen des Hochdruckgefäßes werden nur durch Heben und Senken des Mantels 1 erzielt. Zum Senken wird der am oberen Rand des Mantels aufliegende Deckel 9 durch den Hauptzylinder 13 unter Überwindung der Gegenhaltekraft der Zylinder 4 nach unten bewegt, während zum Heben die Zylinder 4 den Mantel 1 gegen die Preßkraft des Hauptzylinders 13 nach oben bewegen.The changes in volume of the high-pressure vessel necessary for the treatment process are achieved only by raising and lowering the jacket 1. For lowering, the cover 9 resting on the upper edge of the jacket is moved downward by the master cylinder 13 while overcoming the counter-holding force of the cylinder 4, while for lifting the cylinders 4 move the jacket 1 upward against the pressing force of the master cylinder 13.

Die üblichen Bauelemente der Unterkolbenpresse, wie oberer und unterer Querholm, Säulen und Führungen von Mantel 1 und Deckel 9 an den Säulen sind aus Gründen der übersichtlicheren Darstellung auch in den anderen Figuren nicht eingezeichnet.The usual components of the lower piston press, such as the upper and lower cross member, columns and guides of the jacket 1 and cover 9 on the columns are not shown in the other figures for reasons of clarity.

Bei der in Fig. 2 dargestellten Unterkolbenpresse sind die mit Fig. 1 gleichen Bauelemente mit gleichen Bezugszeichen versehen, sodaß sich deren Beschreibung erübrigt. Der Unterschied besteht darin, daß der Deckel 9ʹ über den Fortsatz 11ʹ mit einem oberen Querholm (nicht dargestellt) verbunden ist und nicht bewegt wird, und daß die Volumensänderungen nur durch Bewegung des unteren Kolbens 8ʹ ausgeführt werden. Die Schließkraft gegen den auf die sich durch die Durchmesserdifferenz der unteren Dichtung 7 und der oberen Dichtung 10 ergebende Differenzfläche wirkenden Innendruck üben auch hier die Zylinder 4 aus, nur stützen sich diese gegen den Oberholm ab.In the lower piston press shown in FIG. 2, the components that are the same as in FIG. 1 are provided with the same reference numerals, so that their description is unnecessary. The difference is that the cover 9ʹ is connected via the extension 11ʹ with an upper cross member (not shown) and is not moved, and that the volume changes are carried out only by moving the lower piston 8ʹ. The closing force against the due to the difference in diameter of the lower seal 7 and the upper seal 10 resulting differential area acting internal pressure exert the cylinder 4, only these are supported against the upper spar.
