Description

Die vorliegende Erfindung betrifft eine Vorrichtung zur Zerkleinerung von Objekten, wobei die Vorrichtung einen eine Umfangswand und einen Boden aufweisenden Behälter und einen in einem unteren Bereich des Behälters vorgesehenen Aufnahmekopf aufweist, an dem wenigstens ein Schlagwerkzeug vorgesehen ist, das in dem unteren Bereich des Behälters umläuft.The present invention relates to an apparatus for shredding objects, the apparatus having a container having a peripheral wall and a bottom and a receiving head provided in a lower portion of the container, on which at least one striking tool is provided, which rotates in the lower region of the container ,

Eine Vorrichtung dieser Gattung ist aus der deutschen Patentschrift DE 43 00 784 C2 bekannt. Die bekannte Vorrichtung dient zur Zerkleinerung von zu entsorgenden Geräten, die Hartschaum oder Hartkunststoffe aufweisen, wie beispielsweise Kühlschränken. Da bei der Entsorgung solcher Geräte auch giftige Gase wie Fluorchlorkohlenwasserstoffe frei werden, weist die bekannte Vorrichtung einen gegenüber der Umgebung abgeschlossenen Mahlbehälter auf, aus welchem kein Fluorchlorkohlenwasserstoff während des Mahlprozesses nach außen treten kann. Der Inhalt des nach außen hin abgeschlossenen Behälters wird während des Zermahlens der zu entsorgenden Geräte mit Stickstoff inertisiert. Das Inertgas soll durch die Abgeschlossenheit des Behälters während des Zerkleinerungsvorganges in dem Behälter bleiben, um Staubexplosionen vorzubeugen.A device of this type is known from the German patent DE 43 00 784 C2 known. The known device is used for comminution of equipment to be disposed of hard foam or hard plastics, such as refrigerators. As in the disposal of such devices and toxic gases such as chlorofluorocarbons are released, the known device has a closed to the environment grinding container from which no chlorofluorocarbon can pass out during the milling process. The content of the outwardly sealed container is rendered inert during grinding of the equipment to be disposed of with nitrogen. The inert gas is to remain in the container through the seclusion of the container during the crushing process to prevent dust explosions.

Bedingt durch den Aufbau der bekannten Vorrichtung ist diese zunächst mit dem zu zermahlenden Gut zu befüllen, der Innenraum der Vorrichtung wird nachfolgend inertisiert, daraufhin wird das zu zerkleinernde Gut in der Vorrichtung zermahlen, das Inertgas und die bei der Vermahlung entstehenden Gase danach evakuiert und abschließend das zerkleinerte Mahlgut ausgetragen. Mit der bekannten Vorrichtung ist eine sehr effektive Zerkleinerung von Geräten möglich. Jedoch lässt sich aufgrund der geforderten Abgeschlossenheit eine kontinuierliche Arbeitsweise, gleichbleibend mit homogenem Output, in welcher dem Innenraum der bekannten Zerkleinerungseinrichtung fortlaufend zu zerkleinerndes Gut zugeführt und das zerkleinerte Mahlgut ausgetragen wird, mit der bekannten Vorrichtung nicht realisieren.Due to the structure of the known device, this is first filled with the material to be ground, the interior of the device is subsequently rendered inert, then the material to be crushed is ground in the device, the inert gas and the gases produced during grinding then evacuated and finally the crushed regrind discharged. With the known device, a very effective crushing of devices is possible. However, due to the required seclusion, a continuous mode of operation, consistent with homogeneous output, in which the interior of the known comminution device is continuously fed to comminuted material and the comminuted material is discharged, can not be realized with the known device.

Es ist daher die Aufgabe der vorliegenden Erfindung, eine Zerkleinerungsvorrichtung zur Verfügung zu stellen, welche eine effektive Zerkleinerung von Objekten ermöglicht und dennoch kontinuierlich betrieben werden kann.It is therefore the object of the present invention to provide a comminution device which enables effective comminution of objects and yet can be operated continuously.

Die Aufgabe wird durch eine Vorrichtung zur Zerkleinerung von Objekten der oben genannten Gattung gelöst, bei welcher wenigstens ein Teil der Umfangswand und/oder des Bodens des Behälters siebartig ausgebildet ist, sodass der Behälter wenigstens dort gegenüber der Umgebung offen ist.The object is achieved by a device for comminution of objects of the abovementioned type, in which at least part of the peripheral wall and / or the bottom of the container is designed like a sieve, so that the container is at least there open to the environment.

Da erfindungsgemäß ein Teil der Umfangswand und/oder des Bodens des Behälters siebartig ausgebildet ist, kann durch die wenigstens eine siebartige Öffnung an dem Behälter kontinuierlich zerkleinertes Material aus dem Behälterinneren nach außen ausgetragen werden. Da darüber hinaus von dem Behälter der erfindungsgemäßen Vorrichtung gerade nicht gefordert ist, dass er gegenüber der Umgebung abgeschlossen sein muss, kann dem Behälter der Vorrichtung kontinuierlich zu zerkleinerndes Material zugeführt werden, sodass im Ergebnis eine kontinuierliche Zuführung von zu zerkleinernden Objekten als auch ein kontinuierlicher Austrag von zerkleinertem Material erfindungsgemäß realisierbar ist.Since according to the invention a part of the peripheral wall and / or the bottom of the container is formed like a sieve, can be discharged from the container interior to the outside through the at least one sieve-like opening on the container continuously shredded material. In addition, since the container of the device according to the invention is not required to be sealed off from the environment, material can be continuously fed to the container of the device, resulting in a continuous supply of objects to be shredded as well as a continuous discharge of crushed material according to the invention can be realized.

Aufgrund der siebartigen Ausbildung des Teils der Umfangswand und/des Bodens des Behälters, durch welchen zerkleinertes Material nach außen ausgetragen werden kann, bleibt solches Material, das noch nicht ausreichend genug zerkleinert wurde, in dem Behälter, während Material einer durch das Sieb passenden Größe durch das siebartige Teil der Umfangswand und/oder des Bodens des Behälters aus dem Behälter ausgetragen werden kann. So kann durch die Struktur des siebartigen Teils die Größe bzw. Feinheit des ausgetragenen, zerkleinerten Materials bestimmt werden.Due to the screen-like design of the part of the peripheral wall and / or the bottom of the container, through which shredded material can be discharged to the outside, such material, which has not been sufficiently crushed, remains in the container while material of a size suitable through the sieve the sieve-like part of the peripheral wall and / or the bottom of the container can be discharged from the container. Thus, the size or fineness of the discharged, comminuted material can be determined by the structure of the sieve-like part.

Durch die siebartige Ausbildung des Teils der Umfangswand und/oder des Bodens des Behälters kann zudem bei bestimmten zu zerkleinernden Materialien eine Auffaserung der Oberfläche realisiert werden, wodurch das zerkleinerte Material im Folgenden besser verarbeitbar bzw. verwertbar ist.Due to the sieve-like design of the part of the peripheral wall and / or the bottom of the container, a fuzzification of the surface can also be realized for certain materials to be comminuted, whereby the comminuted material is subsequently better processable or utilizable.

In einer vorteilhaften Ausführungsform der vorliegenden Erfindung ist wenigstens ein Sieb in der Umfangswand in dem unteren Bereich des Behälters vorgesehen, in welchem das wenigstens eine Schlagwerkzeug umläuft. Damit kann das durch das wenigstens eine Schlagwerkzeug zerkleinerte Material direkt an das Sieb geworfen werden, wobei dasjenige zerkleinerte Material, dessen Durchmesser geringer als die Öffnungen des Siebes ist, direkt durch das Sieb aus dem Behälter nach außen ausgetragen werden kann.In an advantageous embodiment of the present invention, at least one sieve is provided in the peripheral wall in the lower region of the container in which the at least one impact tool rotates. Thus, the shredded by the at least one impact tool material can be thrown directly to the screen, the shredded material whose diameter is smaller than the openings of the screen can be discharged directly through the sieve from the container to the outside.

In einem bevorzugten Beispiel der vorliegenden Erfindung ist ein mit einem Austragsschacht gekoppeltes Sieb partiell in der Umfangswand des Behälters vorgesehen. So kann das mit dem wenigstens einen Schlagwerkzeug zerkleinerte Mahlgut, welches unterhalb einer bestimmten Korngröße liegt, durch das Sieb und den damit verbundenen Austragsschacht vorteilhaft aus dem Behälter ausgetragen und daraufhin geeignet gesammelt, weitertransportiert und/oder verarbeitet werden.In a preferred example of the present invention, a screen coupled to a discharge chute is provided partially in the peripheral wall of the container. Thus, the comminuted with the at least one impact tool regrind, which is below a certain grain size, advantageously discharged through the sieve and the associated discharge chute from the container and then suitably collected, further transported and / or processed.

Gemäß einer bevorzugten Weiterbildung der vorliegenden Erfindung ist ein Sieb umlaufend in der Umfangswand des Behälters vorgesehen. Hierdurch kann besonders viel zerkleinertes Material, das durch das wenigstens eine Schlagwerkzeug an die Umfangswand des Behälters geworfen wird, durch das umlaufend vorgesehene Sieb nach außen ausgetragen werden. Um das so ausgetragene Mahlgut vorteilhaft sammeln zu können, kann beispielsweise ein zweiter Mantel um die Umfangswand des Behälters vorgesehen werden, welcher sich zumindest im Bereich des Siebes befindet.According to a preferred embodiment of the present invention, a sieve is provided circumferentially in the peripheral wall of the container. As a result, particularly much shredded material that is thrown by the at least one impact tool to the peripheral wall of the container, are discharged through the circumferentially provided screen to the outside. In order to be able to advantageously collect the grinding material thus discharged, it is possible, for example, to provide a second jacket around the peripheral wall of the container, which is located at least in the region of the screen.

Gemäß einer anderen, ebenfalls vorteilhaften Variante der vorliegenden Erfindung ist im Wesentlichen die gesamte Fläche des Bodens als ein Sieb ausgebildet. Damit kann zerkleinertes Mahlgut einer bestimmten Korngröße über den Boden des Behälters, auf welchen das Mahlgut fällt, ausgetragen werden.According to another, likewise advantageous variant of the present invention, substantially the entire surface of the bottom is formed as a sieve. Thus, crushed millbase of a certain particle size can be discharged via the bottom of the container on which the millbase falls.

Beispielsweise weist der siebartig ausgebildete Teil der Umfangswand und/oder des Bodens eine Vielzahl runder, ovaler, rechteckiger und/oder quadratischer Öffnungen auf. Die Form der Öffnungen kann dabei an die gewünschten Eigenschaften des zu zerkleinernden Materials angepasst werden, ist aber grundsätzlich variabel.For example, the sieve-like formed part of the peripheral wall and / or the bottom of a plurality of round, oval, rectangular and / or square openings. The shape of the openings can be adapted to the desired properties of the material to be shredded, but is basically variable.

Günstigerweise weisen die Öffnungen einen Querschnitt von etwa 75 mm2 bis etwa 2.000 mm2 auf. Hierdurch kann zerkleinertes Material, dessen Korngröße bzw. Faserdurchmesser geringer als der Querschnitt der Öffnungen ist, ausgetragen werden. Durch die geringe Korngröße bzw. Feinfasrigkeit des ausgetragenen zerkleinerten Materials, ist dieses im Weiteren besonders gut verarbeitbar bzw. verwertbar. So kann beispielsweise bei der Zerkleinerung von Ersatzbrennstoffen ein feinfasriges, zerkleinertes Material aus der erfindungsgemäßen Vorrichtung ausgetragen werden, welches besonders gut verbrennbar ist, sodass die Verbrennung nahezu rückstandsfrei erfolgen kann.Conveniently, the openings have a cross-section of about 75 mm 2 to about 2,000 mm 2 . As a result, crushed material whose grain size or fiber diameter is smaller than the cross section of the openings, be discharged. Due to the small grain size or Feinfasrigkeit the discharged comminuted material, this is particularly easy to process or recoverable. Thus, for example, in the comminution of substitute fuels a feinfasriges, crushed material can be discharged from the device according to the invention, which is particularly good combustibility, so that the combustion can be almost residue-free.

Es ist besonders von Vorteil, wenn der Aufnahmekopf an einer von unten in den Behälter eingeführten Antriebswelle vorgesehen ist, die mit einem Antriebsmotor verbunden ist. Somit kann der Aufnahmekopf über die von dem Antriebsmotor angetriebene Antriebswelle das wenigstens eine Schlagwerkzeug rotieren und damit die zu zerkleinernden Objekte vorteilhaft zermahlen.It is particularly advantageous if the pick-up head at one of the bottom of the container introduced drive shaft is provided, which is connected to a drive motor. Thus, the recording head on the drive shaft driven by the drive motor rotate the at least one impact tool and thus advantageously grind the objects to be crushed.

Die Antriebswelle ist vorzugsweise mit einem Keilriemen gekoppelt, der mit einem seitlich des Behälters vorgesehenen Antriebsmotor gekoppelt ist. Über den Keilriemen kann die Antriebswelle und damit der Aufnahmekopf in eine Drehbewegung versetzt werden, sodass das wenigstens eine daran vorgesehene Schlagwerkzeug innerhalb des Behälters rotieren und das zu zerkleinernde Gut zermahlen kann.The drive shaft is preferably coupled to a V-belt coupled to a drive motor provided laterally of the container. Via the V-belt, the drive shaft and thus the receiving head can be set in a rotational movement, so that the at least one impact tool provided thereon can rotate within the container and grind the material to be comminuted.

In einem Beispiel der vorliegenden Erfindung ist das wenigstens eine Schlagwerkzeug flexibel ausgebildet. So ist es möglich, als Schlagwerkzeug eine oder mehrere Ketten zu verwenden, das bzw. die innerhalb des Behälters die zu zerkleinernden Objekte sowohl durch die Wirkung des wenigstens einen flexiblen Schlagwerkzeugs als auch durch die Eigenbewegung und Reibung der zu zerkleinernden Objekte untereinander zermahlen.In one example of the present invention, the at least one impact tool is flexible. Thus, it is possible to use as impact tool one or more chains that grind within the container or the objects to be crushed both by the action of the at least one flexible impact tool and by the proper movement and friction of the objects to be crushed each other.

In einer anderen, ebenfalls empfehlenswerten Ausführungsform der vorliegenden Erfindung ist das wenigstens eine Schlagwerkzeug starr ausgebildet. Auch hiermit lässt sich eine effektive Zerkleinerung des zu zerkleinernden Gutes in Folge der Rotationsbewegung des wenigstens einen Schlagwerkzeuges im unteren Bereich des Behälters erzielen.In another, likewise recommendable embodiment of the present invention, the at least one impact tool is rigid. Hereby, effective comminution of the material to be comminuted as a result of the rotational movement of the at least one striking tool in the lower region of the container can be achieved.

In einem besonders vorteilhaften Beispiel der vorliegenden Erfindung ist die erfindungsgemäße Vorrichtung eine Zerkleinerungsvorrichtung für Ersatzbrennstoffe mit noch enthaltenen Metallanteilen. Durch die siebartige Ausbildung des wenigstens einen Teils der Umfangswand und/oder des Bodens des Behälters der Zerkleinerungsvorrichtung kann aus den zu zerkleinernden Ersatzbrennstoffen (EBS) ein feinfasriges, zerkleinertes Material erzeugt werden. Durch die spezielle Form der Zerkleinerung in der erfindungsgemäßen Zerkleinerungsvorrichtung kann die Oberfläche des zerkleinerten Materials aufgefasert werden, wodurch das zerkleinerte Material im Folgenden besonders gut verbrennen kann, wobei die Verbrennung nahezu rückstandsfrei erfolgt. Dies ist ein besonderer Vorteil gegenüber herkömmlichen Zerkleinerungsvorrichtungen für Ersatzbrennstoffe, welche im Wesentlichen Schneideprozesse nutzen, um die Ersatzbrennstoffe zu zerkleinern, welche im Folgenden mit erheblichen Rückständen verbrennen.In a particularly advantageous example of the present invention, the device according to the invention is a comminuting device for substitute fuels with metal components still present. Due to the sieve-like design of the at least part of the peripheral wall and / or the bottom of the container of the comminuting device, a fine-fiber, comminuted material can be produced from the substitute fuels (EBS) to be comminuted. Due to the special shape of the comminution in the comminuting device according to the invention, the surface of the comminuted material can be frayed, as a result of which the comminuted material can burn particularly well in the following, the combustion taking place virtually without residue. This is a particular advantage over conventional refuse-derived refining devices, which essentially utilize cutting processes to crush the refuse-derived fuels, which subsequently burn with significant residuals.
