Description
Die vorliegende Erfindung betrifft eine Zerkleinerungsvorrichtung mit den im einleitenden Teil des Anspruchs 1 angegebenen Merkmalen. Eine solche Zerkleinerungsvorrichtung ist aus der
Mit der bekannten Vorrichtung ist eine sehr effektive Zerkleinerung von Geräten möglich. Jedoch lässt sich 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.With the known device, a very effective crushing of devices is possible. However, a continuous operation, consistent with homogeneous output, in which the interior of the known comminution continuously fed to comminuted Good 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 Zerkleinerungsvorrichtung nach Anspruch 1 gelöst.The object is achieved by a comminution device according to
Da erfindungsgemäß ein Teil der Umfangswand des Behälters siebartig ausgebildet ist, wird 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 kontinuierlich ausgetragen und kann daraufhin geeignet gesammelt, weitertransportiert und/oder verarbeitet 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 of the container is formed like a sieve, 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 continuously and can then suitably collected, further transported and / or processed. 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 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 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 sieve-like design of the part of the peripheral wall of the container, through which comminuted material can be discharged to the outside, such material, which has not been sufficiently crushed enough, remains in the container, while material of a size suitable through the sieve through the sieve-like part of Circumferential wall 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 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 of the container, it is also possible for a certain amount of material to be comminuted to fibrillate the surface, as a result of which the comminuted material is subsequently better processable or utilizable.
In einer vorteilhaften Ausführungsform der vorliegenden Erfindung ist das 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, the 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.
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 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 has a multiplicity 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.
