Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Streuen von Streugut, insbesondere von Holzspänen, Holzfasern oder ähnlichem, zu Streugutmatten mit einem Streuband und einem Streugutbunker mit einer Austragsvorrichtung zum Aufstreuen des Streugutes auf das Streuband, in deren Bereich eine in einem Winkel zur Horizontalen angeordnete Rutsche vorgesehen ist.The The invention relates to a device for spreading spreading material, in particular of wood chips, Wood fibers or the like, to grit mats with a scatter band and a grit bunker with a Discharge device for spreading the material to be spread on the scattering band, in the area of which is arranged at an angle to the horizontal Slide is provided.
Eine
solche Vorrichtung ist aus der
In der Produktion von Spanplatten und OSB (Oriented Strand Board) kommt es immer wieder dazu, dass Metallpartikel in den Produktionsprozess eingeschleust werden. Diese führen im Produktionsprozess zu Beschädigungen der Anlagen oder zumindest zu Schäden in der hergestellten Holzwerkstoffplatte. Die dadurch nötigen Produktionsunterbrechungen und ggf. Reparaturen der Anlagen sind kosten- und zeitintensiv. Um Metallpartikel aus dem Produktionsprozess herausfiltern zu können, sind an vielen Stellen innerhalb einer Produktionslinie entweder dauermagnetische oder elektromagnetische Abscheidevorrichtungen vorhanden. Diese sorgen dafür, dass ferromagnetische Fremdkörper ausgesondert und so die nachfolgenden Pro duktionseinrichtungen nicht beschädigt werden. Dieses Aussortieren von Metallpartikeln ist nur vor der eigentlichen Streuung effektiv möglich, da nach der Streuung diese magnetischen Einrichtungen nicht sehr effektiv arbeiten, da in einer vergleichsweise dicken Streumatte Metallpartikel nur schwer zu detektieren bzw. zu entfernen sind. Diese gelangen daher in den Produktionsprozess und führen zu den bereits genannten Unterbrechungen und Beschädigungen der Anlagen.In The production of chipboard and OSB (Oriented Strand Board) is coming time and again that metal particles are introduced into the production process become. These lead in the production process to damage the plants or at least to damage in the produced wood-based panel. The thereby necessary Production interruptions and if necessary repairs of the plants are costly and time consuming. To metal particles from the production process to be able to filter out are either permanently magnetic in many places within a production line or electromagnetic separation devices available. These ensure, that ferromagnetic foreign body Separated and so not the subsequent production facilities damaged become. This sorting out of metal particles is only before the actual scattering effectively possible because after scattering these magnetic devices are not very Work effectively, as in a comparatively thick litter mat metal particles difficult to detect or remove. These arrive therefore in the production process and lead to those already mentioned Interruptions and damage the plants.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Streuvorrichtung bereitzustellen, die über einen effektiven Metallabscheider verfügt.Of the The invention is therefore based on the object, a scattering device to provide that over has an effective metal separator.
Die Erfindung löst die Aufgabe dadurch, dass die im Bereich der Austragsvorrichtung vorgesehene Rutsche magnetisch oder magnetisierbar ist.The Invention solves the task in that in the field of discharge provided slide is magnetic or magnetizable.
Das den Streugutbunker über die Austragsvorrichtung verlassende Streugut fällt beim Betrieb der erfindungsgemäßen Vorrichtung auf die im Bereich der Austragsvorrichtung angeordnete Rutsche. Dadurch wird der Pfeilwinkel des Streugutes verändert. Das nichtmagnetische Streugut, beispielsweise Holzspäne oder Holzfasern, rutscht über die Rutsche hinweg und wird auf das Streuband aufgestreut. Vorher wird es beispielsweise über Verteiler und Orienter geführt, wodurch eine gleichmäßige Verteilung und homogene Ausrichtung des Streugutes gewährleistet wird.The the grit bin over the discharge device leaving grit falls during operation of the device according to the invention on the arranged in the discharge device chute. Thereby the arrow angle of the grit is changed. The non-magnetic Scattering material, such as wood chips or wood fibers, slips over the chute away and is scattered on the scattering band. Previously For example, it is about Distributor and orienter, resulting in a uniform distribution and homogeneous alignment of the material to be spread is ensured.
Befinden sich Metallpartikel im Streugut, treffen auch diese nach Verlassen des Streugutbunkers auf die magnetische Rutsche. Durch die magnetische Wechselwirkung zwischen den Metallpartikeln und der magnetischen Rutsche werden die Partikel auf der Rutsche festgehalten und geraten nicht in den weiteren Produktionsablauf. Sie können daher auch nicht in die Streumatte gelangen. Über die Austragsvorrichtung am Ausgang des Streugutbunkers werden die einzelnen Partikel im Streugut stark vereinzelt. Daher treffen die im Streugut enthaltenen Metallpartikel auf die Rutsche und werden zu einem sehr großen Anteil festgehalten.Are located Metal particles in the grit also hit them after leaving of the grit bin on the magnetic chute. By the magnetic Interaction between the metal particles and the magnetic Slide the particles are held on the slide and advised not in the further production process. You can not go into that either Get scattered mat. about the discharge at the exit of the grit bunker are the individual particles are very isolated in the grit. Therefore, the meet in the spreading material contained metal particles on the chute and become to a very big one Share held.
Vorteilhafter Weise ist die Rutsche als Elektromagnet ausgestaltet. Dadurch ist die Reinigung der Rutsche, etwa bei Wartungsstillständen der Vorrichtung, leicht möglich. Wird der Strom, der den Elektromagneten der Rutsche betreibt, abgeschaltet, verliert die Rutsche ihre magnetischen Eigenschaften. Die bis zu diesem Zeitpunkt an der Rutsche festgehaltenen Metallpartikel lösen sich und können einfach entsorgt werden.Favorable Way, the chute is designed as an electromagnet. This is the cleaning of the slide, such as during maintenance shutdowns of Device, easily possible. If the current that operates the electromagnet of the slide, switched off, loses Slide their magnetic properties. The up to this time Metal particles caught on the slide come off and can easily be disposed of.
In einer anderen vorteilhaften Ausgestaltung besteht die Rutsche aus einem permanentmagnetischen Material, beispielsweise einer Magnesium-Neodym-Legierung. Im Vergleich zur Elektromagnet-Lösung spart diese Ausführungsform Strom und damit Kosten. Die Reinigung der permanentmagnetischen Rutsche kann beispielsweise mittels einer einfachen, nichtmagnetischen Edelstahlschaufel geschehen.In In another advantageous embodiment, the chute is made a permanent magnetic material, such as a magnesium neodymium alloy. Compared to the electromagnet solution saves this embodiment Electricity and thus costs. Cleaning the permanent magnetic chute For example, by means of a simple, non-magnetic stainless steel bucket happen.
Besonders vorteilhafter Weise ist der Winkel der magnetischen Rutschen stufenlos einstellbar. Dadurch kann auch der Fallwinkel des Streugutes und damit die Qualität der aufgestreuten Streumatte gesteuert werden. Zudem kann die Verweildauer, also die Zeit, die einzelne Partikel aus dem Streugut auf der Rutsche verbringen, durch den Fallwinkel variiert werden, sodass ggf. im Streugut enthaltene Metallpartikel mit einer größeren Wahrscheinlichkeit festgehalten werden.Especially Advantageously, the angle of the magnetic chutes is stepless adjustable. This also allows the fall angle of the grit and thus the quality the scattered scattered mat are controlled. In addition, the residence time, so the time, the individual particles from the grit on the chute be varied by the fall angle, so possibly in the Contaminated metal particles are held with a greater probability become.
