Abstract

This apparatus consists of two compression moulds (1, 2), of which in each case one pressure rammer (31, 33) is connected to a vibration transmitter (15) and on whose second pressure rammer (30, 32) a pressure is exerted by means of hydraulic cylinders (3, 5). This can be used to compress straw meal by a factor of 9, so that a compact body which can be used as fuel is produced without binder. <IMAGE>

Description

Die vorliegende Erfindung betrifft ein Verfahren zum Verdichten von organischen Stoffen gemäss dem Gattungsbegriff des unabhängigen Patentanspruchs 1, sowie eine Vorrichtung zur Ausübung des Verfahrens nach Patentanspruch 5.The present invention relates to a method for compressing organic substances according to the preamble of independent claim 1, and to a device for carrying out the method according to claim 5.

Bei der Verarbeitung von organischen Stoffen, z.B. von Abfällen, wie Klärschlamm, Müll oder dgl. für deren Weiterverwendung als Brennstoffe wird der Klärschlamm mittels Zyklonen oder mit Trocknungswalzen getrocknet und das entstehende pulverförmige Material wird wenn immer möglich als solches den Kehrichtverbrennungsöfen zugeführt. Es ist bekannt, dass diese Verfahren sehr viel Energie verbrauchen und dass die Wärme von Kehrichtverbrennungsöfen zu grossen Teilen ungenutzt bleibt.When processing organic substances, e.g. waste such as sewage sludge, garbage or the like, for their further use as fuels, the sewage sludge is dried by means of cyclones or with drying rollers and the resulting powdery material is, as far as possible, fed to the waste incinerators. It is known that these processes consume a lot of energy and that the heat from waste incinerators remains largely unused.

Bei der Suche nach Energieträgern zur Wärmeerzeugung gelangte man schon seit längerer Zeit zu Müll, Klärschlamm und sonstigen Abfällen aus organischem Material, wie Holzmehl oder Stroh. Die bindemittellose Brikettierung, die aus der Aufbereitung der geologisch lignistischen oder amorphen Weich-Braunkohle bekannt ist, versagt, weil diese Stoffe bei den üblichen Pressdrücken von 800 bis max. 1500 bar ihre Eigenelastizität nicht verlieren und sich daher nicht vereinigen lassen. Auch die bei der Feinkornbrikettierung üblichen Drücke bis 2000 bar brachten das erwartete Ergebnis nicht.In the search for energy sources for heat generation, waste, sewage sludge and other waste from organic material, such as wood flour or straw, had been found for a long time. The binderless briquetting, which is known from the processing of geologically lignistic or amorphous soft lignite, fails because these substances at the usual pressures of 800 to max. 1500 bar does not lose its own elasticity and therefore cannot be combined. Even the pressures up to 2000 bar that are common in fine grain briquetting did not produce the expected result.

Die Beimengung von Bindemitteln, wie sie in der Ziegel-, Ton- und Kunststoffindustrie für das Brikettieren bekannt ist, oder die Beimengung von 5 - 10%-igem Pechzusatz, wie bei der Verarbeitung von Steinkohlen und Grudekoks mit Pressdrücken von 300 bar bei 80 - 90° C, bringt in diesem besonderen Gebiet keine Lösung.The admixture of binders, as is known in the brick, clay and plastics industry for briquetting, or the admixture of 5 - 10% pitch additive, such as in the processing of hard coal and Grudekoks with pressures of 300 bar at 80 - 90 ° C, brings no solution in this particular area.

Die Aufgabe der Erfindung besteht nun darin, ein Verfahren und eine Vorrichtung anzugeben, mit dem bei geringem Energiebedarf irgendwelche organischen Stoffe direkt verdichtet werden können, wobei beispielsweise bei Klärschlamm die Restflüssigkeit ausgeschieden wird und der Feststoffanteil zu einem kompakten Körper geformt werden kann und organische Abfälle, wie fein zerkleinerter Müll, Holzmehl oder zerkleinertes Stroh, ohne Zugabe von Bindemitteln agglomeriert werden können, so dass sie sich direkt verbrennen lassen.The object of the invention is now to provide a method and a device with which any organic matter is directly compacted with a low energy requirement In the case of sewage sludge, for example, the residual liquid is excreted and the solid content can be formed into a compact body, and organic waste such as finely shredded garbage, wood flour or shredded straw can be agglomerated without the addition of binders, so that they can be burned directly .

Erfindungsgemäss wird dies dadurch erreicht, dass der zu verdichtende Stoff auf eine Schwingungsplatte verbracht und einem Gegendruck ausgesetzt wird und dass die Schwingungsplatte vibriert wird.According to the invention, this is achieved in that the substance to be compressed is placed on a vibrating plate and subjected to a counterpressure and in that the vibrating plate is vibrated.

Ein Ausführungsbeispiel der Erfindung wird anhand der Zeichnung beschrieben. Es zeigen:

  • Fig. 1 eine schematische Darstellung einer erfindungsgemässen Vorrichtung im Aufriss,
  • Fig. 2 eine Draufsicht auf die Formseite eines Pressstempels, und
  • Fig. 3 eine Seitenansicht eines mit Pressstempel gemäss Fig. 2 hergestellten Presslings.
An embodiment of the invention is described with reference to the drawing. Show it:
  • 1 is a schematic illustration of a device according to the invention in elevation,
  • Fig. 2 is a plan view of the mold side of a press ram, and
  • FIG. 3 shows a side view of a compact produced with the press stamp according to FIG. 2.

Die Vorrichtung gemäss Fig. 1 besteht aus zwei Pressformen 1 und 2 mit gegeneinander verfahrbaren Pressstempeln 30, 31 und 32, 33. Die aussenliegenden Pressstempel 30, 32 jeder Pressform 1, 2 sind über Kolbenstangen 4, 6 mit hydraulischen Zylindern 3, 4 verbunden. Die hydraulischen Zylinder 3, 4 sind je mit einer Zuführleitung 7, 9 und einer Wegführleitung 8, 10 mit je einem Absperrventil 11, 12, 13, 14 versehen.The device according to FIG. 1 consists of two press molds 1 and 2 with press dies 30, 31 and 32, 33 which can be moved relative to one another. The outer press dies 30, 32 of each press mold 1, 2 are connected to hydraulic cylinders 3, 4 via piston rods 4, 6. The hydraulic cylinders 3, 4 are each provided with a feed line 7, 9 and a discharge line 8, 10 each with a shut-off valve 11, 12, 13, 14.

Die innenliegenden Pressstempel 31, 33 sind über Kolbenstangen 16, 17 mit einem Schwingungsgeber 15 verbunden. Ueber jeder der beiden Pressformen 1, 2 befindet sich ein Einfülltrichter 21, 22, die zusammen die Bodenfläche eines Vorratsbehälters 23 bilden. Die Oeffnungen der Einfülltrichter 19, 21 sind mit einer Abschlussplatte 18 mit Durchgangsöffnungen 19, 20 verschliessbar. Eine zweite Abschlussplatte 24 befindet sich unter den Pressformen 1, 2. Auch diese zweite Abschlussplatte 24 weist Durchgangsöffnungen auf, die in Gegenwirkung zu den Durchgangsöffnungen in der Abschlussplatte 18 stehen und deshalb in der dargestellten Phase nicht ersichtlich sind.The internal press rams 31, 33 are connected to a vibration sensor 15 via piston rods 16, 17. Above each of the two molds 1, 2 there is a hopper 21, 22, which together form the bottom surface of a storage container 23. The openings of the filling funnels 19, 21 can be closed with an end plate 18 with through openings 19, 20. A second end plate 24 is located under the press molds 1, 2. This second end plate 24 also has through openings which counteract the through openings in the end plate 18 and are therefore not visible in the phase shown.

Die Wirkungsweise einer solchen Vorrichtung ist die folgende:The operation of such a device is as follows:

In der dargestellten Betriebsphase sind die Einfülltrichter 21, 22 über die Durchgangsöffnungen 19, 20 in der Abschlussplatte 18 mit den Hohlräumen zwischen den beiden auseinandergefahrenen Pressstempeln 30, 31 und 32, 33 der Pressformen 1, 2 verbunden. Die zweite Abschlussplatte 24 verschliesst den Hohlraum nach unten und nicht dargestellte seitliche Platten bilden die in der Zeichnung hintere und vordere Oeffnung zwischen den Pressstempeln. Damit kann Feingut aus dem Vorratsbehälter 23 die beiden Hohlräume der Pressformen 1, 2 ausfüllen. Nach dem Verschliessen der Durchgangsöffnungen 19, 20 werden die Absperrventile 7, 9 in den Zuführleitungen 7, 9 geöffnet und die beiden aussenliegenden Pressstempel 30, 32 werden zu den innenliegenden Pressstempeln 31, 33 hin gepresst. Sobald der Druck des Fluids in den Zuführleitungen 7, 9 die volle Presskraft aufgebaut hat, wenn also das Feingut mit einem entsprechenden Druck zusammengepresst ist, wird der Schwingungsgeber 5 in Betrieb gesetzt, wodurch das Feingut im Formhohlraum vibriert wird.In the operating phase shown, the filling funnels 21, 22 are connected via the through openings 19, 20 in the end plate 18 to the cavities between the two press dies 30, 31 and 32, 33 of the molds 1, 2 that have moved apart. The second end plate 24 closes the cavity at the bottom and side plates, not shown, form the rear and front opening in the drawing between the press dies. Fine material can thus fill the two cavities of the molds 1, 2 from the storage container 23. After the passage openings 19, 20 have been closed, the shut-off valves 7, 9 in the feed lines 7, 9 are opened and the two outer press dies 30, 32 are pressed toward the inner press dies 31, 33. As soon as the pressure of the fluid in the feed lines 7, 9 has built up the full pressing force, that is to say when the fine material is pressed together with a corresponding pressure, the vibrator 5 is put into operation, as a result of which the fine material is vibrated in the mold cavity.

Bei gleichbleibendem Druck auf die aussenliegenden Pressstempel 30, 32 bewirkt jede Volumenverkleinerung des Feingutes eine Verkleinerung des Formenhohlraumes, so dass die Schwingungen immer auf aneinandergepresste Partikeln des Feingutes wirken.With constant pressure on the external pressing punches 30, 32, each reduction in volume of the fine material causes a reduction in the mold cavity, so that the vibrations always act on particles of the fine material pressed against one another.

Beispielsweise wurde gemahlenes Stroh auf diese Weise verarbeitet. Der Schwingungserzeuger 5 führte Vibrationen im Frequenzbereich zwischen 10 Hz und 200 Hz aus. Bei Schwingungen mit Amplituden bis etwa 2 mm konnte Material mit einem Volumen von 56 vm3 auf 6 cm3 verdichtet werden. Das Gewicht des Materials betrug 8 g. Nach der Verdichtung wird die zweite Abschlussplatte 24 verschoben, so dass deren Oeffnungen unter den Pressformen liegen. Beim Oeffnen der Formen fallen die Presslinge durch diese Oeffnungen nach unten.For example, ground straw was processed in this way. The vibration generator 5 carried out vibrations in the frequency range between 10 Hz and 200 Hz. When vibrations with amplitudes up to about 2 mm with a volume of material was 56 vm 3 to 6 cm 3 are compressed. The weight of the material was 8 g. After the compression, the second end plate 24 is moved so that its openings lie under the molds. When the molds are opened, the compacts fall down through these openings.

Es hat sich als besonders vorteilhaft erwiesen, wenn die verdichteten Körper eine Kugelform hatten, weil bei diesen die Verdichtung homogen ist, während bei zylindrischer Form die Verdichtung an den ebenen Flächen geringer ist als gegen die Mitte des Zylinders hin. Eine Ansicht auf eine Hälfte einer Pressform 34 ist in Fig. 2 dargestellt. Die Ausnehmungen 35 haben die Form von identischen Kugelkalotten, deren Höhe bei 2 cm Durchmesser angenähert 9 mm beträgt. Damit werden zwischen benachbarten Kugeln 40 Stege 41 gebildet (Fig. 3), in denen das Material ebenso verdichtet ist wie im übrigen Volumen der Kugeln. Beim Transport werden die Kugeln dann an diesen Stellen selbsttätig voneinander getrennt.It has proven to be particularly advantageous if the compacted bodies have a spherical shape, because in these the compression is homogeneous, while in the case of a cylindrical shape the compression on the flat surfaces is less than towards the center of the cylinder. A view of one half of a die 34 is shown in FIG. 2. The recesses 35 have the shape of identical spherical caps, the height of which is approximately 9 mm at a diameter of 2 cm. Thus, webs 41 are formed between adjacent balls 40 (FIG. 3), in which the material is compressed as well as in the remaining volume of the balls. The balls are then automatically separated from one another at these points during transport.

Auf gleiche Weise lässt sich Holzmehl und fein zerteilter Müll verarbeiten. Das Ergebnis ist dann ein brennbares Material, das sich anstelle von Kohle in Oefen jeglicher Art verwenden lässt.Wood flour and finely divided waste can be processed in the same way. The result is a flammable material that can be used in any type of furnace instead of coal.

Anstelle der dargestellten Hydraulikzylinder 3, 5 könnte auch eine Zahnstangenanordnung vorgesehen sein, bei der das Antriebszahnrad über eine Rutschkupplung angetrieben wird.Instead of the hydraulic cylinders 3, 5 shown, a rack and pinion arrangement could also be provided in which the drive gearwheel is driven via a slip clutch.
