Description

Die vorliegende Erfindung betrifft eine Brikettierpresse zur Herstellung länglicher Briketts aus zu verpressendem Pressgut. Wenn als Pressgut reine oder unreine Holzabfälle verwendet werden, so erhält man zu Feuerungszwecken verwendbare Briketts. Verwendet man als Pressgut Metallabfälle, so lassen sich die Briketts als Barren zum Einschmelzen verwenden. Verwendet man als Pressgut Viehfutter, so dienen die Briketts Futterzwecken. Natürlich sind noch ungezählte andere Verwendungszwecke möglich.The present invention relates to a briquetting press for producing elongated briquettes from pressed material to be pressed. If pure or impure wood waste is used as pressed material, briquettes that can be used for firing purposes are obtained. If metal waste is used as pressed material, the briquettes can be used as bars for melting down. If cattle feed is used as pressed material, the briquettes are used for feeding purposes. Of course, countless other uses are possible.

Bei den bekannten Brikettierpressen, mit denen Presslinge für die vorgenannten Verwendungszwecke hergestellt werden, erfolgt das Pressen in einem zylindrischen Behälter, in welchen das Pressgut von der Stirnseite her eingefüllt wird und wo es dann in der Längsrichtung verdichtet wird, worauf es in der Längsrichtung ausgestossen wird. Das hat zwei wesentliche Nachteile: der eine besteht darin, dass die Verdichtung des Pressgutes oft sehr inhomogen ist, dies besonders dann, wenn die Verdichtung in einem rohrförmigen Pressraum von beiden Enden her erfolgt, weil dann in der Mitte oft die Verdichtung wesentlich geringer ist als an den Enden. Bei andern Pressen, bei denen die Verdichtung nur dadurch bewirkt wird, dass das Pressgut durch ein konisches Rohr gepresst wird, entsteht eine grosse Oberflächenreibung, was je nach dem zu verpressendem Gut zu Wärmeschäden führen kann, ein Nachteil, der auch bei zylindrischem Pressraum auftreten kann, wenn die Ausstossgeschwindigkeit nicht hinreichend klein gehalten wird. All diese Nachteile weist nun die erfindungsgemässe Presse nicht mehr auf, da sie durch die im kennzeichnenden Teil des Anspruches 1 aufgeführten Merkmale gekennzeichnet ist. Dadurch, dass das Ausstossen des erzeugten Briketts nicht in der Pressstellung der Matrize erfolgt sondern in einer daneben liegenden Stellung, in welcher das Brikett nur noch in der Matrize liegt und nicht mehr vom Pressstempel festgehalten wird, wird für das Ausstossen wesentlich weniger Kraft benötigt, sodass auch die unter Umständen sehr schädliche Oberflächenreibung nicht mehr entsteht.In the known briquetting presses with which compacts are produced for the aforementioned purposes, the pressing takes place in a cylindrical container, into which the material to be pressed is filled from the front side and where it is then compressed in the longitudinal direction, after which it is expelled in the longitudinal direction . This has two major disadvantages: one is that the compression of the material to be pressed is often very inhomogeneous, especially if the compression is carried out from both ends in a tubular press room, because the compression in the middle is often significantly less than at the ends. With other presses, in which the compression is only achieved by pressing the material to be pressed through a conical tube, there is a large surface friction, which, depending on the material to be pressed, can lead to thermal damage, a disadvantage that can also occur in the case of a cylindrical press space if the ejection speed is not kept sufficiently low. The press according to the invention no longer has all these disadvantages, since it is characterized by the features listed in the characterizing part of claim 1. Because the briquette is not ejected in the pressed position of the die, but in an adjacent position, in which the briquette is only in the die and is no longer held by the press ram, much less force is required for ejection, so that the surface friction, which may be very harmful, no longer arises.

Nachfolgend wird anhand der beiliegenden Zeichnung ein Ausführungsbeispiel der Erfindung beschrieben. In der Zeichnung zeigt

  • die Fig. 1 eine schaubildliche Darstellung der für die Erfindung wesentlichen Teile der Brikettierpresse, wobei die ganze Anlage zum bessern Verständnis in zwei voneinander getrennte Teile zerlegt ist.
An exemplary embodiment of the invention is described below with reference to the accompanying drawing. In the drawing shows
  • 1 is a diagrammatic representation of the parts of the briquetting press essential for the invention, the entire system being broken down into two separate parts for better understanding.

Die Fig. 2 zeigt einen Querschnitt durch den geschlossenen Pressraum.Fig. 2 shows a cross section through the closed press room.

Die in der Fig. 1 dargestellte Brikettierpresse weist einen Maschinensockel 1 auf. Auf diesem ist eine Matrizeneinheit 2 angeordnet, welche aus der in der Richtung des Pfeiles 2a hin und her schiebbaren Matrize 2b und zugehörigen Führungsmitteln 2c sowie in der Zeichnung nicht dargestellten Antriebsmitteln zum Verschieben der Matrize gebildet wird. Die Matrize weist, wie aus der Fig. 2 ersichtlich ist, eine horizontale Rinne 2d auf. Oberhalb der Matrize 2b ist die Trägerplatte 3 für den den Füllraum 4a begrenzenden Schacht 4 angebracht. In diesem Schacht 4 ist ein Stempel 5 vertikal verschiebbar angeordnet, der durch Verschiebeorgane, die in der Zeichnung nur schematisch dargestellt und mit 6 bezeichnet sind, aufwärts und abwärts verschoben werden kann. Bei diesen Verschiebeorganen kann es sich um pneumatisch oder hydraulisch oder hydropneumatisch oder auch anderswie betätigbare Organe handeln, wobei es jedoch nötig ist, dass diese Mittel so dimensioniert sind, dass sie den Stempel 5 nicht nur aufwärts und abwärts verschieben, sondern dass sie ihn auch mit solcher Kraft nach unten pressen können, dass das in der Rinne 2d vorhandene Pressgut verdichtet werden kann.The briquetting press shown in FIG. 1 has a machine base 1. Arranged on this is a die unit 2, which is formed from the die 2b which can be pushed back and forth in the direction of the arrow 2a and associated guide means 2c and drive means (not shown in the drawing) for displacing the die. As can be seen from FIG. 2, the die has a horizontal channel 2d. The support plate 3 for the shaft 4 delimiting the filling space 4a is attached above the die 2b. In this shaft 4, a stamp 5 is arranged to be vertically displaceable, which can be displaced upwards and downwards by means of displacement members, which are only shown schematically in the drawing and are designated by 6. These shifting elements can be pneumatically or hydraulically or hydropneumatically or also other elements which can be actuated, but it is necessary that these means are dimensioned in such a way that they not only move the punch 5 upwards and downwards, but also with it can press downwards such force that the material to be pressed in the channel 2d can be compressed.

Der durch die Rinne 2d und den Stempel 5 begrenzte, im Querschnitt 8-eckige, prismatische Pressraum wird an seinen beiden Stirnseiten durch je einen pneumatisch oder hydraulisch betätigbaren Verdichtungsstempel 7a bzw. 8a begrenzt, von welchem in der Zeichnung auch die -Zylinder und ihre Befestigungen sichtbar sind. Die Zylinder sind als Ganzes mit 7 bzw. 8 bezeichnet.The prismatic press chamber, which is delimited by the channel 2d and the punch 5 and has an octagonal cross-section in cross-section, is delimited on both ends by a pneumatically or hydraulically actuated compression punch 7a or 8a, of which in the drawing also the cylinders and their fastenings are visible. The cylinders are designated as a whole by 7 and 8 respectively.

Ein weiterer Pressstempel, der zum Ausstossen des fertigen Presslings oder Briketts aus der Matrize dient und dessen Verschieberichtung parallel zur Längsachse der Verdichtungsstempel angeordnet ist, ist, wie man aus der Fig. 1 der Zeichnung gut ersehen kann, neben einem der Verdichtungszylinder 7 bzw. 8 angeordnet. Hier ist in der Zeichnung nicht der Stempel selbst sondern nur sein Zylinder sichtbar, der mit 9 bezeichnet ist.Another press stamp, which serves to eject the finished compact or briquette from the die and whose direction of displacement is arranged parallel to the longitudinal axis of the compression stamp, is, as can be clearly seen from FIG. 1 of the drawing, next to one of the compression cylinders 7 and 8 arranged. Here, the stamp itself is not visible in the drawing, but only its cylinder, which is designated by 9.

Dabei ist selbstverständlich die Matrize 2b so zwischen ihren beiden Endstellungen verschiebbar, dass sich die den Pressraum unten begrenzende Rinne 2d in der einen Endstellung der Matrize zwischen den beiden Verdichtungsstempeln 7a und 8a der Druckzylinder 7 bzw. 8 und in der andern Endstellung im Arbeitbereich des Stempels des Ausstosszylinders 9 befindet.The die 2b can of course be displaced between its two end positions in such a way that the groove 2d delimiting the press chamber below in one end position of the die between the two compression dies 7a and 8a of the pressure cylinders 7 and 8 and in the other end position in the working area of the die of the ejection cylinder 9.

An den Schacht 4 ist der Silo 10 zur Lagerung des zu verpressenden Materials angebaut. Der Silo weist als Boden einen sich nach oben erstrekkenden, drehbaren Kegel 11 auf, der motorisch antreibbar ist. Eine Oeffnung 12 verbindet den Silo 10 mit dem durch eine Türe 4b verschlossene Kontrollöffnung versehenen Füllraum 4a, solange sich der Stempel 5 in der in der Fig. 1 dargestellten Lage befindet. Wenn sich hingegen der Stempel 5 im untern Teil des Füllraumes 4a befindet, schliesst er diese Oeffnung 12 ab. Solange nun die Oeffnung 12 offen ist, kann Pressgut aus dem Silo 10 in den Füllraum 4a rieseln. Dieses Hineinrieseln oder Rutschen wird noch dadurch erleichtert, dass der Kegel 11 motorisch in Drehung versetzt wird. Wenn der Füllraum 4a bis an die Oberkante der Oeffnung 12 gefüllt ist, hört der Materialzufluss von selbst auf. Dann wird der Stempel 5 nach unten gefahren, wobei die Steuerung manuell oder automatisch erfolgen kann. Falls die Steuerung manuell erfolgt, ist im Schacht 4 ein Kontrollfenster vorzusehen, um den Füllstand des Füllraumes 4a zu überwachen, Bei automatischer Steuerung kann eine optische oder mechanische Füllraumüberwachung zur Auslösung der Stempelbewegung vorhanden sein oder ein Zeitschalter, der sich entsprechend der von der Art des Pressgutes abhängigen Füllzeit des Füllraumes einstellen lässt. Wenn nun der Stempel 5 durch die Verschiebeorgane 6 nach unten verschoben wird, presst er das im Füllraum 4a vorhandene Pressgut in die Rinne 2d der Matrize 2b und drückt es dort zusammen, was eine gleichmässige Vorverdichtung der ganzen Presscharge zur Folge hat. Wenn der Pressstempel 5 seine untere Endlage erreicht hat, wie das in der Fig. 2 dargestellt ist, bleibt er dort stehen und die beiden seitlich angeordneten Verdichterstempel 7a und 8a beginnen sich gegeneinander zu bewegen und verdichten so das im Pressraum vorhandene Pressgut bis auf die benötigte Dichte, wobei die Endstellung der Pressstempel durch die Länge der zu erzeugenden Briketts vorgegeben oder durch den maximalen Druck, mit welchem die Verfestigung zu erfolgen hat, begrenzt wird.The silo 10 for storing the material to be pressed is attached to the shaft 4. The bottom of the silo has an upwardly extending, rotatable cone 11 which can be driven by a motor. An opening 12 connects the silo 10 to the filling space 4a provided with a control opening closed by a door 4b, as long as the stamp 5 is in the position shown in FIG. 1. If, on the other hand, the stamp 5 is located in the lower part of the filling space 4a, it closes this opening 12. As long as the opening 12 is now open, pressed material can trickle out of the silo 10 into the filling space 4a. This trickling in or sliding is further facilitated by the fact that the cone 11 is rotated by a motor. When the filling space 4a is filled up to the upper edge of the opening 12, the material flow stops automatically. Then the punch 5 is moved down, the control can be done manually or automatically. If the control is carried out manually, a control window is to be provided in the shaft 4 in order to monitor the filling level of the filling space 4a. In the case of automatic control, there can be optical or mechanical filling space monitoring for triggering the stamp movement or a time switch which varies according to the type of Pressing material dependent filling time of the filling space can be set. If the punch 5 is now moved downward by the displacement members 6, it presses the material to be pressed in the filling space 4a into the groove 2d of the die 2b and compresses it there, which results in a uniform pre-compression of the entire press batch. When the press ram 5 has reached its lower end position, as shown in FIG. 2, it stops there and the two compressor rams 7a and 8a arranged on the side begin to move against each other and thus compress the material to be pressed in the press room to the required level Density, the end position of the press ram being predetermined by the length of the briquettes to be produced or being limited by the maximum pressure with which the consolidation has to take place.

Sobald die axiale Verdichtung des Pressgutes, also die Erzeugung des Briketts beendigt ist, werden die beiden Verdichterstempel 7a und 8a in ihre Ausgangslage zurückgezogen und der vertikal verschiebbare Stempel 5 wird soweit angehoben, dass er sich nicht mehr im Bereich der Rinne 2d befindet, jedoch die Oeffnung 12 noch geschlossen hält. Nun wird durch die in der Matrizeneinheit 2 angeordneten Verschiebemittel die Matrize 2b in die andere Endlage verschoben, in welcher sich die Rinne 2d mit dem in ihr befindlichen Brikett im Verschiebeweg des Ausstossstempels des Zylinders 9 befindet. In dieser Stellung, in welcher das Brikett nicht mehr durch den Stempel 5 festgehalten wird, sondern nur noch mit den verhältnismässig schmalen Seitenflächen in der Rinne 2d eingeklemmt ist, genügt zum Ausstossen des Briketts eine verhältnismässig kleine Kraft, die dann zu klein ist, um auf das Pressgut schädliche Wirkungen ausüben zu können.As soon as the axial compression of the pressed material, i.e. the production of the briquette, has ended, the two compression rams 7a and 8a are pulled back into their starting position and the vertically displaceable ram 5 is raised to such an extent that it is no longer in the region of the channel 2d, but the Opening 12 still holds closed. Now, by means of the shifting means arranged in the die unit 2, the die 2b is shifted into the other end position, in which the groove 2d with the briquette located therein is in the displacement path of the ejection punch of the cylinder 9. In this position, in which the briquette is no longer held by the plunger 5, but is only clamped in the groove 2d with the relatively narrow side surfaces, a relatively small force, which is then too small, is sufficient to eject the briquette the pressed material can have harmful effects.

Selbstverständlich wäre es auch möglich, die Ausstossvorrichtung anders anzuordnen, beispielsweise so, dass sie das Brikett vertikal nach oben verschiebt. Dazu müsste der Boden der Rinne 2d vertikal verschiebbar ausgebildet sein. Eine andere Möglichkeit für die weitere Ausgestaltung der erfindungsgemässen Presse könnte auch darin bestehen, die Matrize 2b mit einem elastischen Abschnitt zu versehen, der an der Ausstossstelle ein Aufweiten der Rinne 2d ermöglicht und zur Vermeidung des Aufweitens an der Pressstelle durch ein entsprechendes Widerlager abgestützt wird.Of course, it would also be possible to arrange the ejection device differently, for example in such a way that it displaces the briquette vertically upwards. For this purpose, the bottom of the channel 2d would have to be vertically displaceable. Another possibility for the further configuration of the press according to the invention could also be to provide the die 2b with an elastic section which enables the trough 2d to expand at the ejection point and which is supported by a corresponding abutment to avoid the expansion at the press point.

Nach dem Ausstossen des Briketts wird zuerst der Ausstossstempel des Zylinders 9 in seine Bereitschaftsstellung zurückgezogen und dann wird die Matrize 2b wieder in die Füllstellung zurückgeschoben, der Stempel 5 wird angehoben und der eingangs beschriebene Füllvorgang kann beginnen, worauf sich der Press- und der Ausstossvorgang wiederholt.After the briquette has been ejected, the ejection ram of the cylinder 9 is first withdrawn into its ready position and then the die 2b is pushed back into the filling position, the ram 5 is raised and the filling process described at the beginning can begin, whereupon the pressing and the ejection process are repeated .
