Abstract
Description
Die Erfindung betrifft eine Fördervorrichtung für Schüttgut und/oder Fasermaterial, insbesondere eine Einblasdämmstoff-Fördervorrichtung, umfassend eine Auflockerungsvorrichtung zur Auflockerung des Schüttguts und/oder Fasermaterials, wobei die Auflockerungsvorrichtung aufweist: ein Gehäuse mit einer Längsachse, die der Förderrichtung des zu fördernden Schüttguts und/oder Fasermaterials entspricht, und mindestens ein Auflockerungselement, das eine Welle umfasst, die im Gehäuse um eine Achse drehbar angeordnet und von einem Motor angetrieben ist, wobei die Achse senkrecht zur Längsachse angeordnet ist, wobei an der Welle eine Anzahl Schlagelemente drehfest angebracht sind.The invention relates to a conveying device for bulk material and / or fiber material, in particular a blowing insulation conveying device, comprising a loosening device for loosening the bulk material and / or fiber material, wherein the loosening device comprises: a housing having a longitudinal axis, the conveying direction of the bulk material to be conveyed and / or fiber material, and at least one loosening element comprising a shaft which is rotatably mounted in the housing about an axis and driven by a motor, wherein the axis is arranged perpendicular to the longitudinal axis, wherein on the shaft a number of impact elements are rotatably mounted.

Weitere Lösungen zeigen die
Das Fasermaterial kann dabei Zellulose sein. Sofern, was jüngst bevorzugt zur Anwendung kommt, das Fasermaterial aus Holz besteht, treten besondere Schwierigkeiten auf. Die Holzfasern werden wiederum in gepresster, d. h. in hochverdichteter Form angeliefert, um dann als aufgelockerte Holzfasern zur Dämmstelle, beispielsweise in Hohlkammern eines Dachs, gefördert zu werden. Durch die verschiedenen Strukturen der faserigen Holzpartikel zerfallen diese nicht so leicht in einzelne Fasern, wie dies im Falle von Zellulose der Fall ist.The fiber material may be cellulose. If, what has recently been preferred, the fiber material is made of wood, special difficulties arise. The wood fibers are pressed in turn, d. H. Delivered in highly compressed form, then as fanned wood fibers to Dämmstelle, for example, in hollow chambers of a roof, to be promoted. Due to the different structures of the fibrous wood particles, these do not disintegrate into individual fibers as easily as in the case of cellulose.
Nachteilig ist, dass sich dadurch Hohlkammern nicht vollständig füllen lassen, so dass der gewünschte Dämmeffekt nicht optimal ist. Es entstehen somit Lücken im Dämmbereich, da sich das Fasermaterial nicht bestmöglich verteilt.The disadvantage is that this hollow chambers can not be completely filled, so that the desired Dämmeffekt is not optimal. It arises thus gaps in the Dämmbereich, since the fiber material is not distributed as best as possible.
Der Erfindung liegt die Aufgabe zugrunde, eine Fördervorrichtung der eingangs genannten Art so weiterzubilden, dass es möglich ist, auch schwierig aufzufasernde Materialien, wie insbesondere Holz, hinreichend aufzufasern und optimal zu fördern, so dass das mit dem Fasermaterial zu füllende Volumen gut und Hohlstellen-frei gefüllt werden kann. Der zunächst hochverdichtet vorliegende Dämmstoff soll also in verbesserter Weise aufgefasert werden und sich möglichst gleichmäßig in einem mit ihm zu füllenden Gefache verteilen. Die Vorrichtung soll dabei einfach aufgebaut sein, so dass eine kostengünstige Herstellung möglich ist.The invention has for its object to provide a conveyor of the type mentioned in such a way that it is possible, even difficult aufzufasernde materials, in particular wood, sufficiently aufzufasern and optimally promote, so that the volume to be filled with the fiber material well and Hohlstellen- can be filled freely. The initially highly compressed present insulating material is therefore to be frayed in an improved manner and distribute as evenly as possible in a compartment to be filled with him. The device should be simple in construction, so that a cost-effective production is possible.
Die Lösung dieser Aufgabe durch Erfindung zeichnet sich dadurch aus, dass das Gehäuse als Rohr mit kreisförmigem Querschnitt ausgebildet ist, wobei im Gehäuse in Förderrichtung aufeinander folgend mindestens zwei Auflockerungselemente, vorzugsweise drei Auflockerungselemente, angeordnet sind, wobei zwei in Förderrichtung aufeinander folgende Auflockerungselemente zum gegensinnigen Rotieren ausgebildet sind, wobei sich die Schlagelemente von der Welle bis an den Innenumfang des rohrförmigen Gehäuses erstrecken, wobei in Förderrichtung vor und/oder hinter dem letzten Schlagelement eine Einrichtung zum Einblasen von Luft angeordnet ist.The solution of this object by the invention is characterized in that the housing is designed as a tube with a circular cross-section, wherein in the housing in the conveying direction consecutively at least two loosening elements, preferably three loosening elements are arranged, wherein two consecutive in the conveying direction Auflockerungselemente for opposing rotation are formed, wherein the impact elements extend from the shaft to the inner circumference of the tubular housing, wherein in the conveying direction before and / or behind the last impact element, a device for blowing air is arranged.
Besagte Auflockerungsvorrichtung ist dabei als separates Element vorgesehen, das zwischen der Vorrichtung zur Auflockerung des gepressten Materials (Zellradschleuse) und dem Ende des das aufgefaserte Material einblasenden Schlauchs wirksam angeordnet ist.Said loosening device is provided as a separate element, which is effectively arranged between the device for loosening the pressed material (rotary valve) and the end of the fiber material blown-in hose.
Sind mehr als zwei Auflockerungselemente in Förderrichtung vorgesehen, sieht eine bevorzugte Lösung vor, dass zwei in Förderrichtung aufeinander folgende Auflockerungselemente gegensinnig rotieren. Bei drei Auflockerungselementen rotieren demgemäß das erste und das dritte Auflockerungselement gleichsinnig, während das dazwischen angeordnete Auflockerungselement gegensinnig rotiert.If more than two loosening elements are provided in the conveying direction, a preferred solution provides that two loosening elements following one another in the conveying direction rotate in opposite directions. Accordingly, in the case of three loosening elements, the first and the third loosening element rotate in the same direction, while the loosening element arranged therebetween rotates in opposite directions.
Die Schlagelemente erstrecken sich demgemäß von der Welle bis zum Innenumfang des rohrförmigen Gehäuses. Hierunter ist zu verstehen, dass nur ein für die einwandfreie Funktion ausreichender Spalt zwischen dem radial außenliegenden Ende der Schlagelemente und dem Gehäuse-Innenumfang bleibt, wenn das Schlagelement dem Gehäuse-Innenumfang am Nähesten kommt. Dieser Spalt liegt bevorzugt im Bereich zwischen 3 und 30 mm, vorzugsweise zwischen 5 und 15 mm.The striking elements accordingly extend from the shaft to the inner periphery of the tubular housing. This is to be understood that only a sufficient gap for proper function between the radially outer end of the striking elements and the housing inner circumference remains when the striking element comes closest to the housing inner circumference. This gap is preferably in the range between 3 and 30 mm, preferably between 5 and 15 mm.
Die Schlagelemente können sich von der Welle radial weg erstrecken. Es ist auch möglich, dass sich die Schlagelemente von der Welle zumindest abschnittsweise unter einem Winkel, vorzugsweise zwischen 10° und 50°, zur radialen Richtung weg erstrecken.The striking elements may extend radially away from the shaft. It is also possible for the impact elements to extend away from the shaft at least in sections at an angle, preferably between 10 ° and 50 °, to the radial direction.
Ein besonders guter Auflockerungseffekt wird erreicht, wenn in einem in Förderrichtung vorne liegenden Bereich des Gehäuses ein erstes Auflockerungselement angeordnet ist, wobei sich die Schlagelemente von der Welle des ersten Auflockerungselements radial weg erstrecken, und dass in einem in Förderrichtung nachfolgenden Bereich ein zweites Auflockerungselement angeordnet ist, wobei sich die Schlagelemente von der Welle des zweiten Auflockerungselements von der Welle zumindest abschnittsweise unter dem Winkel zur radialen Richtung weg erstrecken.A particularly good loosening effect is achieved if a first loosening element is arranged in a region of the housing lying in the conveying direction, the impact elements extending radially away from the shaft of the first loosening element, and a second loosening element being arranged in a region following in the conveying direction wherein the striking elements extend from the shaft of the second loosening element away from the shaft at least in sections at an angle to the radial direction.
Dabei können die Schlagelemente an einem von der Welle beabstandeten Ort auch miteinander verbunden sein, beispielsweise durch einen Ring, der einen etwas geringeren Durchmesser aufweist als der Innendurchmesser des rohrförmigen Gehäuses.In this case, the impact elements can be connected to each other at a location spaced from the shaft, for example by a ring having a slightly smaller diameter than the inner diameter of the tubular housing.
Die Schlagelemente können über eine formschlüssige Verbindung, insbesondere über ein Mehreckprofil, mit der Welle drehfest verbunden sein.The impact elements can be rotatably connected via a positive connection, in particular via a polygonal profile, with the shaft.
Ein Schlagelement kann auch mit einem Nabenteil verbunden, insbesondere verschweißt, sein und das Nabenteil dann über die formschlüssige Verbindung mit der Welle drehfest verbunden sein.A striking element can also be connected to a hub part, in particular welded, and the hub part can then be non-rotatably connected via the positive connection with the shaft.
Eine weitere Verbesserung des Auflockerungseffekts und eine verbesserte Weiterförderung des aufgefaserten Materials werden dadurch erreicht, dass in Förderrichtung vor und/oder hinter dem in Förderrichtung letzten Schlagelement eine Einrichtung zum Einblasen von Luft angeordnet ist. Diese Einrichtung kann als Ringelement ausgebildet sein, bei dem über dem Umfang eine Anzahl Lufteinblasdüsen angeordnet sind. Durch winkelige Anstellung der Lufteinblasdüsen kann dem aufgefaserten Material ein Drall im Förderschlauch verliehen werden, was die Förderung des Materials unterstützt.A further improvement of the loosening effect and improved further promotion of the fiberized material are achieved in that a device for blowing in air is arranged in the conveying direction before and / or behind the last impact element in the conveying direction. This device can be designed as a ring element, in which a number of air injection nozzles are arranged over the circumference. Angular adjustment of the air injection nozzles, the fiberized material can be imparted a twist in the delivery hose, which supports the promotion of the material.
Ferner hat es sich als vorteilhaft erwiesen, wenn im Bereich des ersten Auflockerungselements - sofern mehrere hiervon vorgesehen sind - Mittel zum Einblasen von Luft in das Gehäuse (Rohr) vorgesehen sind (wie oben erwähnt), d. h. ein Zusatzgebläse. Bei hohem Materialdurchsatz verbessert dies die Zerfaserung des Materials. Ferner ist dies bei hohen Dämmstärken (bis zu 40 cm Dicke der Dämmschicht) sehr vorteilhaft.Furthermore, it has proved to be advantageous if in the region of the first loosening element - if several thereof are provided - means for blowing air into the housing (pipe) are provided (as mentioned above), ie an auxiliary fan. At high material throughput, this improves the fraying of the material. Furthermore, this is very advantageous for high insulation thicknesses (up to 40 cm thickness of the insulating layer).
Eine besonders gute Zerfaserung und Förderung des Materials wird erreicht, wenn sowohl am Ende der Auflockerungsvorrichtung als auch am Ende des Schlauchs jeweils besagte Einrichtungen zum Einblasen von Luft vorgesehen sind, bevorzugt auch am Anfang der Auflockerungsvorrichtung.A particularly good defibration and promotion of the material is achieved when both said end of the loosening device and at the end of the tube each said means are provided for blowing air, preferably at the beginning of the loosening device.
Die Schlagelemente eines Auflockerungselements, die auf der Welle angeordnet sind, bildet also eine Art Rotationsgitter, das drehangetrieben im Gehäuse angeordnet ist.The impact elements of a loosening element, which are arranged on the shaft, thus forming a kind of rotation grid, which is arranged rotationally driven in the housing.
Das rohrförmige Gehäuse mit den erfindungsgemäß ausgebildeten Schlagelementen, die nahe bis an den Gehäuse-Innenumfang heranreichen, erlaubt eine effiziente Auffaserung des zu fördernden Materials mit dem wesentlichen Vorteil, dass eine sehr kompakte und platzsparende Vorrichtung vorliegt, die leicht zu transportieren ist. Dies ist wegen des Anwendungszwecks der Vorrichtung wichtig, da diese mobil sein muss.The tubular housing with the striking elements according to the invention, which come close to the housing inner circumference, allows efficient fibrillation of the material to be conveyed with the significant advantage that there is a very compact and space-saving device that is easy to transport. This is important because of the purpose of the device since it must be mobile.
