Description
Die Erfindung betrifft eine Vorrichtung zum Transport hochdisperser Pulver und ein Verfahren zu ihrer Befüllung und Entleerung.The invention relates to a device for transport highly dispersed Powder and a method for its filling and emptying.
Der Umgang mit schüttfähigen Stoffen mit extrem niedriger Schüttdichte bereitet in verschiedener Hinsicht Probleme. Sowohl die Hersteller als auch die Endverbraucher sind damit konfrontiert, dass solche Stoffe schon bei geringster Luftkonvektion Staub aufwirbeln. Die Staubentwicklung muss vermieden werden, um Personal, das mit dem Gut umgehen muss, vor gesundheitlichen Schäden durch Einatmen des Staubs zu bewahren. Darüber hinaus verursacht die geringe Schüttdichte erhöhte Transportkosten, weil das Verhältnis Gebindegewicht zu Füllgewicht groß ist und entsprechend viel Verpackungsmaterial benötigt wird.Dealing with bulk materials with extremely low Bulk density causes problems in several ways. Either the manufacturers as well as the end users are confronted with it, that such substances even at the slightest air convection Stir up dust. Dust generation must be avoided personnel who have to deal with the good, before health Damage caused by inhalation of the dust. About that In addition, the low bulk density causes increased transport costs, because the ratio of container weight to filling weight is large is and accordingly much packaging material is needed.
Aus EP-A 0 773 159 (US-A 5682929) ist ein Verfahren zum mehrmaligen
Befüllen und Entleeren mit schüttfähigem Gut mit geringer
Schüttdichte bekannt. Der darin beschriebene Gewebecontainer,
der sogenannte Big-Bag oder auch Super-Bag, besitzt eine Füllkapazität
von 90 bis 350 kg. Der Gewebecontainer besteht aus
flexiblem, luftdurchlässigem Gewebe, bevorzugt ein.ein- oder
mehrlagiges Kunststoffgewebe, mit mindestens einer Zugangsöffnung.
Die Befüllung dieser Gewebecontainer erfolgt mittels Vakuumabfüllsystemen.
Dabei wird der Gewebecontainer mit Unterdruck
beaufschlagt und das Gut durch die geöffnete Zugangsöffnung
in den Gewebecontainer gesaugt, bis ein vorbestimmtes
Füllgewicht erreicht ist. Das Gas tritt dabei verteilt über die
gesamte Oberfläche des Gewebecontainers aus. Beim Befüllen wird
das Gut, ähnlich wie beim Abfüllen in Säcke, reversibel verdichtet,
ohne dass seine Struktur dabei zerstört wird.From EP-
Die genannten Gebinde weisen jedoch eine Reihe von Nachteilen auf, die durch die flexiblen Großgebinde aus EP 0982238 A beseitigt werden. Diese flexiblen Gebinde, sind dadurch gekennzeichnet, dass sie aus mindestens zwei übereinander liegenden Lagen bestehen, wobei eine innere Lage aus unbeschichtetem, luftdurchlässigem Gewebe besteht, eine äußere Lage staubdicht und feuchtesperrend beschichtet ist und diese Lagen durch eine spezielle Nahtausführung so miteinander verbunden sind, dass die Entlüftung des Gebindes nur durch diese möglich ist.However, the mentioned containers have a number of disadvantages on, which is eliminated by the flexible bulk containers from EP 0982238 A. become. These flexible containers are characterized that they consist of at least two superimposed Layers are made, with an inner layer of uncoated, air permeable fabric, an outer layer dustproof and damp barrier is coated and these layers by a special seam design are interconnected so that the venting of the container is only possible through this.
Diese flexiblen Großgebinde sind zwar feuchteundurchlässig und ermöglichen eine große Gebindestabilität und Staubdichtheit, allerdings sind sie von der Füllmenge her begrenzt und es ist wünschenswert das Großgebinde so zu gestalten, dass Befüllung und Entleerung beschleunigt und genau dosiert werden können.Although these flexible bulk containers are moisture impermeable and allow a high level of dry stability and dust tightness, however, they are limited in their capacity and it is desirable to design the bulk container so that filling and emptying can be accelerated and accurately metered.
Diese Aufgabe wird gelöst durch einen Container mit einer Oberkante, einer Unterkante und einer mit einer Tür versehenen Rückseite enthaltend einen Inliner, dadurch gekennzeichnet, dass der Inliner aus mindestens zwei übereinander liegenden Lagen besteht, wobei eine innere Lage aus unbeschichtetem, luftdurchlässigem Gewebe besteht, eine äußere Lage staubdicht und feuchtesperrend beschichtet ist und diese Lagen durch eine spezielle Nahtausführung so miteinander verbunden sind, dass die staubfreie Entlüftung des Gebindes nur durch diese Naht möglich ist, wobei der Inliner im Container reversibel befestigt ist und mindestens eine Befüllöffnung und eine Entleeröffnung besitzt.This object is achieved by a container with a top edge, a lower edge and one provided with a door Backside containing an inliner, characterized that the inliner of at least two superimposed layers consists of an inner layer of uncoated, air-permeable Fabric is dustproof, and an outer layer damp barrier is coated and these layers by a special Seam execution are so interconnected, that the Dust-free venting of the container only possible through this seam is, with the inliner is reversibly mounted in the container and has at least one filling opening and an emptying opening.

Bei dem Container handelt es sich vorzugsweise um einen weltweit gebräuchlichen Standard-Transportcontainer. Der Inliner entspricht in seinem Aufbau dem in EP 0982238 A beschriebenen Aufbau des Großgebindes, wobei der Inliner jedoch derart gestaltet ist, dass er den Innenraum eines Standardcontainers vollständig ausfüllt. Vorzugsweise ist der Inliner so gestaltet, dass sich die in EP 0982238 A beschriebenen Nahtausführungen des Inliners in Längsrichtung des Containers an dessen Ober- und Unterkanten befinden. Die Befüllöffnung des Inliners hat vorzugsweise die Form eines Befüllstutzens bestehend aus einem fest mit dem Inliner verbundenen Gewebeschlauch. Der Gewebeschlauch besteht vorzugsweise aus dem gleichen Material wie der Inliner. Der Befüllstutzen besitzt vorzugsweise eine Länge kleiner 100 cm und vorzugsweise einen Durchmesser zwischen 5 und 40 cm.The container is preferably one worldwide common standard transport containers. The inliner corresponds in its structure to that described in EP 0982238 A. Structure of the large package, but the inliner designed in such a way is that he has the interior of a standard container completely filled out. Preferably, the inliner is designed that the seam designs described in EP 0982238 A of the liner in the longitudinal direction of the container at the Upper and lower edges are located. The filling opening of the inliner is preferably in the form of a filling nozzle consisting of a fabric hose firmly connected to the inliner. The fabric hose is preferably made of the same material as the inliner. The filling nozzle preferably has a length less than 100 cm and preferably a diameter between 5 and 40 cm.
Die Entleeröffnung entspricht in Form und Größe vorzugsweise der Befüllöffnung.The emptying opening corresponds in shape and size preferably the filling opening.
Um eine formstabile Aufhängung des Inliners im Container bei der Befüllung und Entleerung zu erreichen, ist der Inliner vorzugsweise mittels mehrerer Fixierschlaufen an den Ösen und Befestigungsstegen im Innenraum des Containers reversibel befestigt (Fig. 1). Vorzugsweise handelt es sich um 1 bis 10 Fixierschlaufen je Längskante des Inliners. Jede Fixierschlaufe ist vorzugsweise mit einer Überwendelungsnaht an dem Inliner befestigt. Da Standardcontainer im Inneren unterschiedliche Befestigungspunkte, in der Regel Ösen oder Stege, aufweisen, der Inliner aber genormte und fest fixierte Schlaufen besitzt, wird eine Flexibilität zum Einhängen der Fixierschlaufen des Inliners vorzugsweise dadurch erreicht, dass man mehrere Ösen (Stege) des Containers mit einem Band verbindet und dieses Band durch die Fixierschlaufen laufen lässt.To a dimensionally stable suspension of the liner in the container at To achieve the filling and emptying, the inliner is preferably by means of several fixing loops on the eyelets and fastening webs reversibly fastened in the interior of the container (Fig. 1). Preferably, it is 1 to 10 Fixierschlaufen per longitudinal edge of the inliner. Each fixation loop is preferably attached to the inliner with an over-lap seam. Since standard containers have different attachment points inside, usually eyelets or webs, have, the inliner but has standardized and firmly fixed loops becomes one Flexibility for hanging the fixing loops of the inliner preferably achieved by having several eyelets (webs) of the container connects to a band and this band through Run the fixation loops.
Durch die Entlüftung des Inliners über seine gesamte innere Oberfläche wird während des Befüllvorganges eine reversible, die Produkteigenschaften nicht verändernde Verdichtung des hochlufthaltigen Feststoffes ermöglicht. Erst dadurch kann ein hoher Befüllgrad des Containers/Inliners erreicht werden.By venting the liner over its entire inner Surface becomes reversible during the filling process, the product features non - altering compaction of the product hochlufthigen solid allows. Only then can one high filling level of the container / inliner can be achieved.
Die Erfindung betrifft ferner ein Verfahren zum Befüllen eines erfindungsgemäßen Containers.The invention further relates to a method for filling a Containers according to the invention.

Im Gegensatz zu dem aus EP-A 0 773 159 bekannten Verfahren wird
erfindungsgemäß nicht mit Unterdruck gearbeitet, sondern das
Produkt in den Inliner mit Druck eingefüllt, wobei der Druckabbau
(Luft) nicht über eine gesonderte Öffnung erfolgt, sondern
das Entlüften des Inliners vorzugsweise über die gesamte Oberfläche
der inneren Gewebelage des Inliners in einen Zwischenbereich
zwischen innerer Gewebelage und äußerer Gewebelage erfolgt
und aus diesem Zwischenbereich die weitere Entlüftung
nach Außen über die Nähte des Inliners erfolgt.In contrast to the method known from EP-
Bei der Befüllung des Containers wird vorzugsweise ein Befüllgitter (Fig. 2) in die rückseitige Türöffnung des Containers eingesetzt. Dadurch wird dort die Ausbuchtung des Inliners während des Befüllens vermieden und ein problemloses Schließen der Türen des Containers nach dem Befüllen des Inliners sichergestellt.When filling the container is preferably a Befüllgitter (Fig. 2) in the rear door opening of the container used.
