Abstract
Description
Verfahren und Einrichtung der Zerkleinerung von festen Stoffen zu Feinspän@@ oder masern and-*nren Verdichtung Die Erfindung betrifft ein verfahren der Zerkleinerung von festen Stoffen, wie Holz und Pflanzenstengel zu feinen Spänen, Mehlen oder Fasern und das sich anschliessende Verdichten zu Pellets oder Briketts, sowie die entsprechende Einrichtung zur Durchführung des Verfahrens.Procedure and equipment for the comminution of solid materials too Feinspän @@ or grain other compaction The invention relates to a method the shredding of solid materials such as wood and plant stalks into fine chips, Flours or fibers and the subsequent compression into pellets or briquettes, as well as the appropriate facility to carry out the procedure.
Es ist bekannt, Holzstämme, Holzzweige, holzabfälle und Pflanzenstengel (z.B. Mais, Stroh) durch Schneiden, Reißen, Brechen, Hacken und Spalten zu zerkleirern. Für eine feinspnige, mehlige Zerkleinerung reichen diese Operationen nicht aus.It is known to have logs, branches, waste wood and plant stems (e.g. corn, straw) by cutting, tearing, breaking, chopping and splitting. These operations are not sufficient for fine-grain, floury comminution.
Ein anschließendes Mahlen, das zu einem Feinheitsgrad führt, wie er z.B. für das Brikettieren oder Kompestieren erwünscht ist, erfordert einen zusätzlichen, hohen Leistungsbedarf.A subsequent grinding that leads to a degree of fineness like him e.g. for briquetting or compesting, requires an additional, high power requirement.
Aufgabe der Erfindung ist es, in einem lrrbeitsgang und bei geringerem Energiebedarf feste Stoffe, wie Holz oder Pflanzenstengel zu feinen Spänen, Mehlen oder Fasern zu zerkleinern und das so aufbereitete Material zu verdichten.The object of the invention is, in one work step and with less Energy requirement of solid materials such as wood or plant stalks for fine chips, flours or to shred fibers and to compress the processed material.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß eine an sich bekannte spanende Zerkleinerung zu feinen Spänen und gröberen Teilen mit einer Nachzerkleinerung überlagert wird. ])ie Einrichtung zu diesem Verfahren besteht aus einem rotor mit fe-inzahnigen, taumelnd angeoineten Scheiben, der mit einem eh.iuse umgeben ist und an seiner Tnnenseite mit Leisten belegt ist, sowLe Lochungen fiir den /suetritt des zerkleinerten hutes autwsi&t..Ein solcher Mantel bewirkt eine Nachzerkleinerung des Gutes; das Material unterliegt solange der Einwirkung der rotierenden Werkzeuge in Verbindung mit den Leisten, die als Gegenschneide wirken, bis es genügend fein durch die Offnungen des Mantels austreten kann.This object is achieved according to the invention in that a per se known cutting size reduction to fine chips and coarser parts with a secondary size reduction is superimposed. ]) The device for this process consists of a rotor with fine-toothed, tumbling anointed discs, which is surrounded by an eh.iuse and covered with strips on the inside is, as well as perforations for the / suetritt of the shredded hat autwsi & t .. Such a coat causes a re-shredding of the goods; the material is subject to the action for as long the rotating tools in connection with the strips, which act as a counter-blade, until it can emerge finely enough through the openings in the jacket.
Die Feinzahnung der taumelnci rotierenden Säge scheiben erfordert dabei erfahrungsgemäß nur einen relativ geringen Leistungsaufwand , beruhend auf den hohen örtlichen Druck der Zähne.The fine toothing of the tumbling saw discs requires experience has shown that only a relatively small amount of work is required, based on the high local pressure of the teeth.
Nachschneideeinrichtungen, ausgebeildet als Messertrommeln mit einem Lochmantel, sind für Halmgut bekannt.Regrooving devices, designed as knife drums with a Perforated casing, are known for stalks.
Sie sind für feste Stoffe, wie Hölzer,nicht geeignet und erreichen trotz hohen Energieaufwands auch nicht den Feinheitsgrad von Sägemehl.They are not suitable for solid materials such as wood and do not achieve them In spite of the high expenditure of energy, not the fineness of the sawdust either.
Die erfindungsgemäße Einrichtung zur Durchftihrung des vorstehenden Verfahrens weist eine kompakte relativ leichte Bauweise auf,die für einen mobilen Einsatz in Forst zur Verarbeitung von AbfallhOlz oder in Gartenbaubetrieben zur Kompostierung von Abfällen, wie Hölzer und anderes biologisches Material von Vorteil ist.The inventive device for performing the foregoing Method has a compact, relatively lightweight design, which is suitable for a mobile Use in forest for processing waste wood or in horticultural companies Composting of waste, such as wood and other biological material, is advantageous is.
Für die Kompostierung bewirkt die gleichmäßige Feinstzerkleinerung zu Sägespänen oder Fasern eine rasche Umsetzung des Materials.For composting, the even finest shredding causes to sawdust or fibers a rapid conversion of the material.
Für die Verminderung des Transportvolumens und auch für Brennzwecke ist eine Werdichtung des Materials wiins(henswert. Eine Verarbeitung von Abfallholz im Forst und Holzabfäi3er.verrchieenr:Art zu Briketts führt zu einem markt fähigen Produkt.For reducing the transport volume and also for burning purposes A sealing of the material is worthwhile. A processing of waste wood in the Forst und Holzabfäi3er.verrchieenr: Kind to briquettes leads to one marketable product.
Die Brikettierpresse fäßt sich ebenfalls in kompakter Bauweise unter den gelochten Bereich des Mantels anordnen. Die Abwärme des Antriebsmotors läßt sich zur Trocknung der Späne verwenden, indem die warme Abluft und die Brenngase des Motors zwischen Preßschnecke und Rotor eingeführt werden; eine Vortrocknung frischer Späne verbessert die Haltbarkeit der Briketts.The briquetting press is also compact arrange the perforated area of the jacket. The waste heat from the drive motor leaves Use yourself to dry the chips by using the warm exhaust air and the combustion gases of the motor are inserted between the press screw and the rotor; a pre-drying fresh chips improves the shelf life of the briquettes.
In den Figuren 1 und 2 ist ein Ausführungsbeispiel der Erfindung dargestellt.In Figures 1 and 2, an embodiment of the invention is shown.
Der Rotor 1 hesteht aus rotierenden, zur Welle taumelnd ateordneten Sägescheiben 3. Er ist von eiem Mantel 4 umgeben. Die auf Distanz stehenden Scheiben bestreichen damit infolge ihrer Taumelbewegung den gesamten Querschnitt des Einführungkanals 5. Dieser Kanal 5 führt etwa tangential zum Rotor 1 und ist nach oben gerichtet sodaß Knüppel oder Stengel von den Zähnen der Scheibe eingezogen werden, wobei deren b'ißenmasse diesen Vorging einleitet und unterstützt. I)ie sich hin und her bewegende Zenspanung verhindert ein Aufheizen oder Absägen des eingeführten Materials, wie das bei einer parallelen Scheinbenanordnung der Fall wäre. Das Ende eines hnüppels oder quer eingeführte Zweite gelangen nur teilweise zerkleinert in den Spalt zwischen Rotor 1 und Mantel 4. Sie finden einen Widerstand an den l.e k.ten (, und werden von den Sägeblättern nichzerkleirrrt, wobei die Größe der Bochungen 7 den Feinheitsgrad der Nachzerkleinerung bestimmt.The rotor 1 consists of rotating ateordered staggering to the shaft Saw disks 3. It is surrounded by a jacket 4. The disks standing at a distance thus coat the entire cross section of the introduction channel as a result of their tumbling motion 5. This channel 5 leads approximately tangentially to the rotor 1 and is directed upwards so that billets or stalks are drawn in by the teeth of the disc, with their b'issen mass initiates and supports this procedure. I) ie moving back and forth Machining prevents the material being fed in from being heated up or sawed off, such as that would be the case with a parallel dummy plane arrangement. The end of a bargain or transversely introduced second ends only partially crushed into the gap between Rotor 1 and jacket 4. You will find a resistance on the l.e k.ten (, and are not crushed by the saw blades, whereby the size of the bumps 7 determines the degree of fineness of the post-shredding.
Sägespäne und nachzerkleinertes Gut fallen durch die Lochungen 6 damit nach außen.Sawdust and re-shredded material fall through the perforations 6 with it outward.
@@ In Fig,r2 ist unter dem gelochten Bereich des Mantels 4 eine Preßschnecke 8 mit Preßkanal 9 angeordnet. Das irdie Schnecke einfallenden Material wird so zu einem Brikettstrang 10 verdichtet. Das über das Schneckenende hinausragende Wellenende 11 hinterläßt im Brikett eine Röhre, die eine Nachtrocknung oder Verfeuerung begünstigt. Beim Brikettieren feuchteren Gutes kann durch diese Rähre Dampf entweichen, der durch Reibungswärme entstanden ist. Zwischen Preßschnecke 8 und Mantel 4 mündet eine Leitung ein, durch die warme Luft oder Gase 12 eintreten können, sodaß das zerspannte Gut nachgetrocknet wird. Diese Gase 12 können im Querstrom durch den Stutzen 13 oder durch den Einftihrkanal 4 wieder austreten. @@ In Fig, r2 is a press screw under the perforated area of the shell 4 8 arranged with a press channel 9. The material falling on the snail becomes like this a strand of briquettes 10 compressed. The shaft end protruding beyond the end of the screw 11 leaves a tube in the briquette that favors subsequent drying or combustion. When briquetting moist goods, steam can escape through this tube caused by frictional heat. Between the press screw 8 and the jacket 4 opens a line through which warm air or gases 12 can enter, so that the machined material is dried afterwards. These gases 12 can cross-flow through the Nozzle 13 or exit again through the inlet channel 4.
Durch die Öffnung 15 kann Dampf durch die Öffnung 16 ein oder mehrere Zuschlagstoffe 17 eingeführt werden, wie das an sich beim Verdichten bekannt ist.Through the opening 15 steam can through the opening 16 one or more Aggregates 17 are introduced, as is known per se when compacting.
Anstelle der taumelnden Sägescheiben 3 kann auch eine Trommel mit aufgesetzten Zähnentverwendet werden tFig. 3). - Leerseite-Instead of the tumbling saw disks 3, a drum can also be used attached teeth are not used. 3). - blank page-
