Abstract

The invention relates to a process for producing dimensionally stable briquets from chip, fiber, dust or sheet-like material to be pressed: by means of a briquetting press (1), the material to be pressed is firstly fed by a motor-operated feed device (17, 18, 19) to a precompacting piston (15) and precompacted by the pre-press plate of the latter in a receiving chamber (16). Further compaction is then carried out in a mold box (8) by a press piston (12) that is moved at right angles thereto; in order to control the quantity of material to be pressed received in the mold box (18), a displacement transducer (22) measuring the travel of the press piston (12) is used and controls the feed device motor (19) via a control device (23). The pressure of the precompacting piston (15) is set fixedly by the control device (23) for the respective type of material to be pressed, and the quantity of material to be pressed is controlled by using the displacement transducer (22) in conjunction with a revolution counter (20), which measures the number of revolutions of the feed device (17, 18, 90).

Description

BRIKETTIERPRESSE UND IHRE VERWENDUNG  BRIKETTIERPRESSE AND ITS USE
Die Erfindung betrifft ein Verfahren nach dem Oberbegriff des Anspruchs 1 sowie eine Brikettierpresse zur Durchführung des Verfahrens nach den Ansprüchen 1 und 2. The invention relates to a method according to the preamble of claim 1 and a briquetting press for carrying out the method according to claims 1 and 2.
Ein derartiges Verfahren und eine gattungsgemäße Brikettierpresse sind aus der EP 0 367 859 B1 bekannt. Dort wird die gegen den Presswiderstand des Pressguts von einer Pressplatte des Vorverdichterkolbens erreichte Endposition gemessen, und die Zuführmenge und/oder der Druck des in die Aufnahmekammer aufgenommenen Pressguts wird abhängig von der gemessenen Endposition des Vorverdichterkolbens gesteuert. Für die Regelung der Brikettlänge wird auch ein mit dem Presskolben ge- Such a method and a generic briquetting press are known from EP 0 367 859 B1. There, the end position reached against a press resistance of the pressed material from a pressure plate of the booster piston is measured, and the supply amount and / or the pressure of the pressed material received in the receiving chamber is controlled depending on the measured end position of the booster piston. For the regulation of the briquette length, a
BESTÄTIGU GSKOPIE koppelter Wegaufnehmer eingesetzt. Mit diesem Wegaufnehmer wird der Druck des Vorverdichterkolbens erhöht oder verringert, und dann wird mittels des mit dem Vorverdichterkolben in Verbindung stehenden Wegaufnehmers indirekt die Einschaltzeit des Motors der Zuführeinrichtung geregelt. Dadurch kann keine genaue Brikettlänge erreicht werden. CONFIRMATION GSKOPIE coupled displacement transducer used. With this transducer, the pressure of the supercharger piston is increased or decreased, and then the on-time of the engine of the feeder is controlled indirectly by means of the path sensor communicating with the supercharger piston. As a result, no exact briquette length can be achieved.
Dabei ist jedoch nachteilig, dass die Regelung bei niedrigem Vorverdichterdruck (unter 80 bar) im Vorverdichter durch die Wandreibung ungenau und erst ein Brikett später wirksam wird, wenn der Vorpresskolben noch ein Brikett vom vorhergehenden Pressvorgang vorgepresst hat. Dadurch können überlange oder zu kurze Briketts entstehen. Ferner muss der Vorverdichterdruck bei unterschiedlicher Struktur des Pressguts, beispielsweise bei feinem Staub aus einer Holzart und bei groben Hackschnitzeln derselben Holzart, sehr unterschiedlich gesteuert werden. Diese Wirkung verstärken noch wechselnde Holzarten, beispielsweise Weich- oder Hartholz, da die- se ebenfalls ein unterschiedliches Verdichtungsverhältnis aufweisen. Die Enddichte ist bei Holzbriketts für Hart- und Weichholz 1. However, it is disadvantageous that the control at low Vorverdichterdruck (below 80 bar) in the supercharger by the wall friction inaccurate and only a briquette later becomes effective when the pre-pressing a briquette has pre-pressed from the previous pressing process. As a result, overlong or too short briquettes can be created. Furthermore, the precompressor pressure must be controlled very differently with different structure of the pressed material, for example fine dust from one type of wood and coarse wood chips of the same type of wood. This effect is exacerbated by ever-changing types of wood, for example softwood or hardwood, since these also have a different compression ratio. The final density of wood briquettes for hard and soft wood is 1.
Die Aufgabe der vorliegenden Erfindung besteht darin, ein Verfahren der im Oberbegriff des Anspruchs 1 genannten Art und eine Brikettierpresse der im Oberbegriff des Anspruchs 3 genannten Art zu schaffen, mit denen (sofort) eine möglichst genaue Brikettlänge erreichbar ist. The object of the present invention is to provide a method referred to in the preamble of claim 1 and a Briquetting press mentioned in the preamble of claim 3, with which (immediately) the most accurate briquette length is reached.
Diese Aufgabe wird mit den Merkmalen der Ansprüche 1 und 3 gelöst. Gemäß einer vorteilhaften, weiteren Ausbildung des Verfahrens gemäß der Erfindung werden die mit dem Umdrehungszahlmesser gemessenen Umdrehungszahlen der Zuführeinrichtung mit der durch den Wegaufnehmer bestimmten Umdrehungs- zahl verglichen, und danach wird die nötige Umdrehungszahl des Zuführeinrich- tungsmotors eingestellt. This object is achieved with the features of claims 1 and 3. According to an advantageous, further embodiment of the method according to the invention, the rotational speeds of the feeder measured with the revolution counter are determined by the revolution determined by the displacement transducer. number and thereafter, the necessary number of revolutions of the feed motor is set.
Gemäß einer vorteilhaften, weiteren Ausbildung der Brikettierpresse gemäß der Er- findung ist ein Umdrehungszahlmesser mit der Zuführeinrichtung gekoppelt und aus- gangsseitig mit der Steuereinrichtung verbunden. According to an advantageous further development of the briquetting press according to the invention, a revolution counter is coupled to the supply device and connected on the output side to the control device.
Gemäß einer vorteilhaften, weiteren Ausbildung der Brikettierpresse gemäß der Erfindung ist der Wegaufnehmer kontinuierlich messend elektronisch ausgebildet. According to an advantageous further development of the briquetting press according to the invention, the displacement transducer is designed to be continuously measuring electronically.
Diese und weitere Merkmale der Erfindung werden nun anhand eines Ausführungsbeispiels näher erläutert. Es zeigen: These and other features of the invention will now be explained in more detail with reference to an embodiment. Show it:
Fig. 1 einen schematischen Schnitt durch eine Brikettierpresse und Fig. 1 is a schematic section through a Briquetting press and
Fig. 2 ein Steuerungsschema für die Brikettierpresse der Fig. 1 . FIG. 2 shows a control scheme for the briquetting press of FIG. 1. FIG.
In Fig. 1 ist eine Brikettierpresse 1 dargestellt, die auf einem Rahmen 2 aufgebaut ist, der auf einem Fußboden 3 steht. Die Brikettpresse 1 umfasst einen auf dem Rahmen 2 stehenden Hauptzylinder 4, der über Stangen 5, 6 mit einer auf dem Rahmen 2 stehenden Gegenplatte 7 verbunden ist. An die Gegenplatte 7 schließt sich nach innen ein Formkasten 8 an, dessen Innenraum 9 durch einen Schieber 10 gegen die Gegenplatte 7 abgeschlossen ist und in einen Vorverdichterkasten 1 1 mündet. Der Innenraum 9 hat einen rechteckförmigen Querschnitt entsprechend dem gewünsch- ten Brikettquerschnitt. Der Vorverdichterkasten 1 1 hat gegenüber dem Innenraum 9 eine weitere, rechteckförmige Öffnung, in der ein rechteckiger Presskolbenabschnitt 12 geführt wird. An diesen Abschnitt 12 schließt sich ein zylinderförmiger Presskol- benabschnitt 12' an, der mittels Öl über einen Hydraulikanschluss 13 in Richtung auf den Innenraum 9 und über einen Hydraulikanschluss 14 zurück bewegbar ist. In Fig. 1, a briquetting press 1 is shown, which is constructed on a frame 2, which stands on a floor 3. The briquetting press 1 comprises a master cylinder 4 standing on the frame 2, which is connected via rods 5, 6 to a counter-plate 7 standing on the frame 2. To the counter plate 7 closes inwardly to a molding box 8, the interior 9 is closed by a slide 10 against the counter-plate 7 and opens into a Vorverdichterkasten 1 1. The interior 9 has a rectangular cross section corresponding to the desired briquette cross section. The Vorverdichterkasten 1 1 has over the inner space 9 a further, rectangular opening in which a rectangular plunger section 12 is guided. This section 12 is followed by a cylindrical compression piston benabschnitt 12 ' , which is movable back by means of oil via a hydraulic connection 13 in the direction of the interior 9 and via a hydraulic connection 14.
Der Vorverdichterkasten 11 weist die Form einer rechteckigen Röhre auf, die senk- recht zur Bewegungsrichtung des Presskolbens 12, 12' steht und in dem ein Vorverdichterkolben 15 geführt wird. Im Vorverdichterkasten 11 ist dadurch ein Vorpress- raum 16 gebildet. Seitlich am Vorverdichterkasten 1 ist ein nach oben offener Behälter 17 befestigt, der unterhalb der maximalen Auszugsstellung des Vorverdichterkolbens 15 in den Vorverdichterkasten 11 mündet. Im Behälter 17 ist als Zuführein- richtung eine Zuführschnecke 18 angeordnet, die von einem Schneckenmotor 19 angetrieben wird. Am Schneckenmotor 19 ist ein Umdrehungsmesser 20 angebracht. The supercharger box 11 has the shape of a rectangular tube, which is perpendicular to the direction of movement of the plunger 12, 12 ' and in which a Vorverdichterkolben 15 is guided. In the pre-compression box 11, a pre-compression space 16 is thereby formed. The side of the supercharger box 1, an upwardly open container 17 is attached, which opens below the maximum extension position of the Vorverdichterkolbens 15 in the Vorverdichterkasten 11. In the container 17, a feed screw 18, which is driven by a worm motor 19, is arranged as the feed device. On the worm motor 19, a revolution meter 20 is attached.
Über der Öffnung des Behälters 17 ist ein oben offenes, motorbetriebenes Rührwerk 21 befestigt, in das Pressgut von oben eingegeben wird und das zur Pressgutzer- kleinerung und Zuführung des Pressguts zur Zuführschnecke 18 dient. Above the opening of the container 17, an open-top, motor-driven agitator 21 is fixed, is entered in the pressed material from above and used for pressing Gutzer- kleinerung and feeding the pressed material to the feed screw 18.
Die Brikettierpresse 1 arbeitet allgemein in folgender Weise. Das Pressgut wird über das Rührwerk 21 im Behälter 17 zur Zuführschnecke 18 gefördert. Von dort gelangt eine bestimmte Pressgutmenge mittels der motorbetriebenen Zuführschnecke 18 in den Vorverdichterkasten 11. Der Vorverdichterkolben 15 wird mit einem festgelegten Druck nach unten gedrückt, bis sein Boden etwa die unteren Öffnungen des Vorverdichterkastens 11 erreicht hat, wobei die Pressgutmenge in dem dadurch gebildeten Aufnahmeraum vorverdichtet wird. Dann wird Öl auf den Hydraulikanschluss 13 gegeben und damit mittels des Kolbenabschnitts 12 zumindest ein Teil der durch den Vorverdichterkolben 15 eingeschlossenen Pressgutmenge in den Innenraum 9 ge- presst und zu einem Brikett weiterverdichtet. Dann wird der Schieber 10 geöffnet und das Brikett über eine gestrichelt angedeutete Öffnung in der Gegenplatte 7 ausgestoßen. Je nach Pressgut wird das Pressverfahren gemäß der DE 3333766 C2, Fig.3 verwendet. Die vorliegende Erfindung gilt jedoch für alle Verfahren. Um nun sofort eine gleichmäßige, von der Pressgutart unabhängige Brikettlänge zu gewährleisten, wird eine Regelung verwendet, wie sie in der Fig. 2 in Verbindung mit Fig. 1 angedeutet ist. The briquetting press 1 generally operates in the following manner. The material to be pressed is conveyed via the agitator 21 in the container 17 to the feed screw 18. From there, a certain amount of pressed material passes through the motor-driven feed screw 18 in the Vorverdichterkasten 11. The Vorverdichterkolben 15 is pressed with a predetermined pressure down until its bottom has reached about the lower openings of the Vorverdichterkastens 11, wherein the amount of pressed material precompressed in the receiving space thus formed becomes. Then oil is added to the hydraulic port 13 and thus pressed by means of the piston portion 12 at least a portion of the enclosed by the Vorverdichterkolben 15 amount of pressed material into the interior 9 and further compressed into a briquette. Then, the slider 10 is opened and the briquette ejected via a dashed lines indicated opening in the counter-plate 7. Depending on the pressed material, the pressing method according to DE 3333766 C2, Fig.3 is used. However, the present invention applies to all methods. In order to ensure a uniform briquette length which is independent of the type of press material, a regulation is used, as indicated in connection with FIG. 1 in FIG.
Als Regelungsmittel ist an der Stange 5 ein Wegaufnehmer 22 befestigt, der hier bei- spielsweise aus drei Schaltern besteht, die durch den Presskolben 12, 12' beim Pressvorgang durch einen mit diesem verbundenen Kontakt 22' betätigbar sind. Die in Fig. 2 gezeigte Steuereinrichtung 23, die Teil einer nicht weiter dargestellten Ablaufsteuerung ist, ist mit dem Kontakt 22' eingangsseitig verbunden. Sie ist ferner eingangsseitig mit dem Umdrehungszahlmesser 20 und ausgangsseitig mit dem Mo- tor 19 der Zuführeinrichtung 17, 18 verbunden. As a control means on the rod 5, a displacement sensor 22 is attached, which consists here, for example, of three switches, which are actuated by the plunger 12, 12 ' in the pressing operation by a contact 22 ' connected thereto. The control device 23 shown in FIG. 2, which is part of a sequence control, not shown, is connected to the input 22 'on the input side. It is also connected on the input side to the revolution counter 20 and on the output side to the motor 19 of the supply device 17, 18.
Die Regelung erfolgt folgendermaßen. Die Zuführschnecke 18 fördert beispielsweise zwei Umdrehungen. Der Vorverdichter presst mit einem fest eingestellten Druck bis zu einer vorgegebenen Position des Vorverdichterkolbens 15. Der Presskolben 12 presst die in der Aufnahmekammer vorverdichtete Pressgutmenge mit einem vorgegebenen Druck in den Innenraum 9, damit die für die Brikettqualität wichtige, gewünschte Dichte erreicht wird. Da durch die ünterschiedliche Verdichtbarkeit der verschiedenen Holzarten und Korngrößen sich die Brikettlänge und somit auch das Stückgewicht ändert, muss die Brikettlänge für das folgende Brikett (sofort) geändert werden. Der Wegaufnehmer 22, 22' meldet der Steuereinrichtung 23, dass das Brikett beispielsweise zu kurz war, und dann erhöht die Steuereinrichtung 23 die Umdrehungen der Zuführschnecke. Sinngemäß werden die Umdrehungen bei zu langem Brikett vermindert. Dazu errechnet die Steuereinrichtung 23 die entsprechende Einschaltzeit für den Motor 19. Bei zu langem Brikett wird vom Kontakt 22' nur der erste (rechte) Schalter 22 erreicht, und dann wird die letzte Einschaltzeit verringert. Beim Erreichen des zweiten (mittleren) Schalters 22 bleibt die Einschaltzeit gleich; dies entspricht der richtigen Brikettlänge. Bei zu kurzem Brikett wird der dritte (linke) Schalters 22 erreicht, und dann wird die Einschaltzeit verlängert. Der Umdrehungszahlmesser 20 misst dabei, wieviele Umdrehungen tatsächlich ausgeführt worden sind. The regulation takes place as follows. The feed screw 18 conveys for example two revolutions. The pre-compressor presses with a set pressure to a predetermined position of the Vorverdichterkolbens 15. The plunger 12 presses the pre-compressed in the receiving chamber amount of pressed material with a predetermined pressure in the interior 9, so that important for the briquette quality, desired density is achieved. Since the different compactness of the different types of wood and grain sizes changes the briquette length and thus also the piece weight, the briquette length for the following briquette has to be changed (immediately). The displacement sensor 22, 22 ' notifies the control device 23 that the briquette was too short, for example, and then the control device 23 increases the revolutions of the feed screw. Analogously, the revolutions are reduced at too long briquette. For this purpose, the control device 23 calculates the corresponding Engine On Time 19. If the briquette is too long, only the first (right) switch 22 is reached by the contact 22 ' and then the last on time is reduced. When the second (middle) switch 22 is reached, the switch-on time remains the same; this corresponds to the correct briquette length. If the briquette is too short, the third (left) switch 22 is reached, and then the switch-on time is extended. The revolution counter 20 measures how many revolutions have actually been carried out.
Der Wegaufnehmer 22, 22' ist hier zu Erläuterungszwecken als dreistufiger Schalter dargestellt. Vorzugsweise wird aber der Wegaufnehmer elektronisch ausgebildet, weil die einzelnen Positionen einfacher mittels der Steuereinrichtung 23 vorgegeben werden können und auch andere Schaltpunkte für den Maschinenablauf erreichbar sind. Die Erfindung ist nicht an die Fertigung von rechteckförmigen Briketts gebunden. Es können auch Vorverdichterkästen und Pressräume für einen runden Brikettquerschnitt oder jeden anderen Querschnitt verwendet werden. The transducer 22, 22 ' is shown here for illustrative purposes as a three-stage switch. Preferably, however, the transducer is electronically formed because the individual positions can be specified more easily by means of the control device 23 and other switching points for the machine sequence can be achieved. The invention is not tied to the production of rectangular briquettes. It is also possible to use pre-compression boxes and press rooms for a round briquette cross-section or any other cross-section.
