Description

Die Erfindung betrifft ein Verfahren zum Behandeln von Kompost, Biomasse od.dgl. Aufgabegut sowie eine dafür geeignete Vorrich­tung.The invention relates to a method for treating compost, biomass or the like. Feed material and a suitable device.

Die Abgabe derartigen Haufwerks ist in unterschiedlichen Korn­größen oder aber als sogenannte Mittelfraktion erwünscht, in der wenigstens zwei Korngrößenklassen zusammengemischt sind. Ange­sichts dessen hat sich der Erfinder das Ziel gesetzt, ein ein­faches Verfahren zum Trennen des Aufgabegutes zu schaffen sowie eine Vorrichtung dazu, die kostengünstig herzustellen und zu be­trieben ist. Zur Lösung dieser Aufgabe führt das Trennen des Haufwekes auf einer Siebfläche, deren Maschen bzw. Sieblöcher in Richtung des Förderstromes des Aufgabegutes in wenigstens zwei Zonen unter­schiedlicher Maschen- oder Lochweite angeordnet werden, wobei das Aufgabegut zum Trennen in wenigstens zwei Kornfraktionen zuerst der Zone engerer Maschen- bzw. Lochweite aufgegeben und zu der/den anderen Zone/n gefördert sowie zum Absieben einer Mischfraktion die Förderrichtung umgekehrt wird.The discharge of such aggregate is desired in different grain sizes or as a so-called middle fraction in which at least two grain size classes are mixed together. In view of this, the inventor has set itself the goal of creating a simple method for separating the feed material and a device for this, which can be produced and operated inexpensively. This problem is solved by separating the pile on a screen surface, the meshes or screen holes of which are arranged in the direction of the flow of the feed material in at least two zones of different mesh size or hole size, the feed material for separating in at least two grain fractions first of all the zone of narrower meshes - or hole width given and conveyed to the other zone (s) and the conveying direction is reversed for screening a mixed fraction.

Eine dafür besonders geeignete Vorrichtung weist eine an sich be­kannte Siebtrommel auf, deren Maschen oder Sieblöcher in zumindest zwei unterschiedlichen Größen oder Durchmessern vorgesehen und in Bereichen jeweils gleicher Lochgrößen angeordnet sind, wobei die Größe der Sieblöcher oder Lochungen in Achsrichtung der Sieb­trommel von deren einen Stirnseite zur anderen Stirnseite abnimmt. Führt man das Aufgabegut zuerst über die Mantelfläche mit den kleineren Sieblöchern, so wird die entsprechende kleine Korn­fraktion ausgesiebt; nachfolgend entstehen -- in Abhängigkeit von der Anzahl der eineander nachgeschalteten Lochweitenunterschiede -- mehrere Fraktionen. Leitet man das Aufgabegut indessen an der an die größte Lochweite anschließenden Trommelstirnseite ein, wird jene Mittelfraktion ausgesiebt, deren Obergrenze von jener größten Lochweite bestimmt ist.A device which is particularly suitable for this has a sieve drum known per se, the meshes or sieve holes of which are provided in at least two different sizes or diameters and are arranged in regions of the same hole sizes, the size of the sieve holes or perforations in the axial direction of the sieve drum from one end face to the other other face decreases. If you first pass the feed material over the lateral surface with the smaller sieve holes, the corresponding small grain fraction is sieved out; subsequently - depending on the number of the different hole width differences connected - several fractions. If, however, the feed material is introduced at the end of the drum that adjoins the largest hole size, the middle fraction whose upper limit is determined by that largest hole size is screened out.

Dazu hat es sich als günstig erwiesen, die Siebtrommel beidends offen zu gestalten und sie mit in ihren Innenraum ragenden Ein­läufen mit zugerodnetem Zuförderorgan zu versehen. Dieses Zuför­derorgan bestimmt die jeweils gewünschte Aufgabestirnseite, und ihm kann zudem eine etwa mittige Aufgabe zugeordnet sein.For this purpose, it has proven to be advantageous to make the sieve drum open at both ends and to provide it with inlets protruding into its interior with an assigned feed element. This feed element determines the respective desired end face of the task, and it can also be assigned an approximately central task.

Nach einem weiteren Merkmal der Erfindung kann die Förderrichtung des Aufgabegutes durch ein reversierbar ausgebildetes Förderorgan bestimmt werden, etwa eine in gewünschter Richtung wandernde Transportschaufel im Trommelinneren, die von der kleinen zur größten Lochung fördert und umgekehrt werden kann.
Bevorzugt ist eine erfindungsgemäße Ausführungsform, bei der die Siebtrommel -- etwa in der Mitte ihrer Länge -- in einem Nei­gungswinkel schwenkbar gelagert ist, so daß die Neigungsrichtung die Förderrichtung zu bestimmen vermag.According to a further feature of the invention, the conveying direction of the feed material can be determined by a reversible conveying element, for example a transport scoop which moves in the desired direction inside the drum and which can convey from the small to the largest perforation and vice versa.
An embodiment according to the invention is preferred in which the screen drum is pivotably mounted at an angle of inclination, approximately in the middle of its length, so that the direction of inclination can determine the direction of conveyance.

Nach einem weiteren Merkmal der Erfindung sind im Trommelinnenraum noch Schaufelbleche angebracht, die gegebenenfalls radial in den Innenraum einragen und denen Transportschaufeln zugeordnet sein können. Letztere weisen bevorzugt zur Trommelachse hin geneigt Kanten auf und können auch selbst zur Trommelachse geneigt sein.According to a further feature of the invention, blade plates are also mounted in the interior of the drum, which protrude radially into the interior if necessary and to which transport blades can be assigned. The latter preferably have edges inclined towards the drum axis and can themselves also be inclined towards the drum axis.

Bevorzugt ist die durch das Schwenklager gelegte Radialebene der Siebtrommel bezüglich deren Einbauten Symmetrieebene; beidseits der durch das Schwenklager gelegten Radialebene der Siebtrommel können die unterschiedlichen Durchmesser der Sieblöcher vorgesehen sein.The radial plane of the sieve drum laid through the pivot bearing is preferred with respect to its built-in plane of symmetry; the different diameters of the sieve holes can be provided on both sides of the radial plane of the sieve drum through the pivot bearing.

Andere günstige Merkmale und Kennzeichen der Vorrichtung sind den Unteransprüchen zu entnehmen.Other favorable features and characteristics of the device can be found in the subclaims.

Eine Siebtrommel 1 der Längen lagert mittig auf einem -- von ei­nem Sockelgestell 26 getragenen -- Neigungsverstellantrieb 8 so, daß sie aus der horizontalen Stellung gem. Fig. 1 in eine ge­strichelt dargestellte rechte -- und entsprechend in eine linke -- Neigungslage überführt werden kann. Hierzu dienen Kolben / Zylin­der-Einheiten 5.A sieve drum 1 of the lengths is centered on a - supported by a base frame 26 - inclination adjustment drive 8 so that they gem from the horizontal position. Fig. 1 in a dashed right - and accordingly in a left - tilt position can be transferred. Piston / cylinder units 5 are used for this.

Dieser Siebtrommel 1 wird Kompost, Biomasse od.dgl. Rohmaterial über ein darüber liegendes Verteilförderband 6 zugeleitet, welches dieses Haufwerk von einem mittig aufgebenden Zuförderorgan 7 übernimmt. Vertikale Abstützungen 9 des Sockelgestells 26 halten jeweils einen Einlauftrichter 10 bzw. 10m einer Zulaufschurre 11 bzw. 11m, welche in Fig. 1 in das offene linke bzw. rechte Ko­nusende 1k der Siebtrommel 1 einragen.This sieve drum 1 is compost, biomass or the like. Raw material is fed via an overlying distribution conveyor belt 6, which takes over this heap from a feeder 7 which is positioned in the center. Vertical supports 9 of the base frame 26 each hold an inlet funnel 10 or 10 m of an inlet chute 11 or 11 m , which protrude into the open left or right cone end 1 k of the screening drum 1 in FIG. 1.

Jene Einlauftrichter 10, 10m sind oberhalb de Trommelachse A vor­gesehen, ihre geschlossenen Einlaufschurren 11, 11m ragen in den Trommelinnenraum 1i ein; das Aufgabematerial kann über der Horizontalachse A der Siebtrommel in diese eingebracht werden. Das Aufgabematerial wird nach seinem Durchlauf am anderen Ende durch eingebaute Austragsschaufeln 13 ausgetragen (Fig. 4).Those inlet funnels 10, 10 m are provided above the drum axis A, their closed inlet chutes 11, 11 m protrude into the drum interior 1 i ; the feed material can be introduced into the screening drum via the horizontal axis A. After passing through, the feed material is discharged at the other end through built-in discharge blades 13 (FIG. 4).

Auf der Siebtrommel 1 sind im gewählten Ausführungsbeispiel auf der linken Trommelhälfte Lochsiebe mit großen Sieblöchern 14 montiert, auf der rechten Trommelhälfte hingegen solche mit kleineren Sieblöchern 15. In der in Fig. 1 wiedergegebenen Stel­lung gelangt dem Aufgabetrichter 10m zugeführtes Hauferk bzw. dessen feinere Siebfraktion in eine unterhalb der Siebtrommel 1 angeordnete Aufnahmekammer 16, nächstgröberes Material wird durch die Sieblöcher 14 in eine linke Aufnahmekammer 17 gebracht, das Überkorn über die beschriebenen Austragsschaufeln 13 in eine bei 18 angedeutete Außenbox.On the screen drum 1 are in the selected embodiment on the left drum half perforated screens mounted with large screen holes 14, however, those 15 on the right drum half having smaller sieve holes In the shown in Fig. 1 position the hopper reaches 10 m supplied Hauferk or its finer screen fraction In a receiving chamber 16 arranged below the sieve drum 1, the next coarser material is brought through the sieve holes 14 into a left receiving chamber 17, the oversize particles via the discharge blades 13 described into an outer box indicated at 18.

Durch die Einstellung des Trommelneigungswinkels w kann die Durch­laufzeit des abzusiebenden Materials verlangsamt oder beschleunigt werden.By adjusting the drum inclination angle w, the throughput time of the material to be screened can be slowed down or accelerated.

Auf der linken Seite der Fig. 1 aufgegebenes Material gelangt zuerst auf die grobmaschige Trommelseite mit der groben Lochung 14 und fließt über die in Pfeilrichtung x zum Austrag 12 (Pfeil in Fig. 1). Hierdurch wird in der Grobfraktion enthaltener Feinanteil vorab durch die Sieblöcher 15 ausgetragen; es entsteht so eine Mittelfraktion.Material fed in on the left-hand side of FIG. 1 first reaches the coarse-meshed drum side with the coarse perforations 14 and flows in the direction of the arrow x to the discharge 12 (arrow in FIG. 1). As a result, the fine fraction contained in the coarse fraction is discharged beforehand through the screen holes 15; it creates a middle fraction.

Die Siebtrommel 1 weist gemäß Fig. 3 längsverlaufende durchgehende Schaufelbleche 19 auf, die das Aufgabegut ständig anheben und auf die jeweils gegenüberliegende Siebfläche schleudern. Dieser Vor­gang ist wiederum durch Einstellung von Schnell- oder Langsamlauf den gewünschten Erfordernissen angepaßt.According to FIG. 3, the screening drum 1 has continuous, continuous blade plates 19 which constantly raise the feed material and hurl it onto the opposite screen surface. This process is in turn adapted to the desired requirements by setting high-speed or slow-speed.

Zusätzlich sind an den Schaufelblechen 19 Transportquerschaufeln 20 angebracht, die das Material zurücktransportieren und länger im Trommelteil halten (angepaßt durch die Neigung w der Siebtrommel 1).In addition, 19 transport transverse blades 20 are attached to the blade plates, which transport the material back and hold it longer in the drum part (adapted by the inclination w of the sieve drum 1).

Die Transportschaufeln 20 haben eine besondere Formgebung, dank derer z.B. Müllsäcke oder Papiertüten od.dgl. durch die Schaufel­bleche 19 sowie spitz zugeordnete Transportschaufeln 20 auf­gerissen und deren Inhalt geleert wird.The transport blades 20 have a special shape, thanks to which e.g. Garbage bags or paper bags or the like. torn open by the blade plates 19 and the transport blades 20 assigned to a point and their contents are emptied.

Durch die Wahl einer geeigneten Drehzahl kann wahlweise z.B. organischer Hausmüll besser ausgesiebt werden; für das Aus­sortieren von Hausmüll können wahlweise bei 14 und 15 Bleche mit gleicher Sieblochung oder Maschenweite gewählt werden. Mit der Verstellung des Neigungswinkels w können Absiebqualität sowie Leistung günstig ausgeglichen werden, d.h. das Ausgabegut kann in der Siebtrommel 1 für eine bessere Aussiebung zurückgehalten werden.By choosing a suitable speed, e.g. organic household waste can be better screened; For sorting out household waste, you can choose between 14 and 15 trays with the same perforation or mesh size. By adjusting the angle of inclination w, the quality of the sieve and the performance can be balanced out cheaply, i.e. the output material can be retained in the screening drum 1 for better screening.
