Abstract
Description
Bei derartigen Behältern ist die Form insofern eine bedeutsame Größe als diese eben nicht aus reinen Festigkeitserwägungen heraus gewählt werden kann. Im allgemeinen Behälterbau wählt man Druckbehälter in ihren Abmessungen und in ihren Wanddicken so, dass das Verhalten gegenüber der Druckbeanspruchung optimal ist. Demzufolge gelangt man bei den meisten Ausführungen zu zylindrischen Behältern oder kugelförmigen Behältern, die zudem noch den Vorteil erbringen, dass sie bei geringstem Materialaufwand das größte Volumen einschließen.The shape of such containers is important Size than this just because of strength considerations can be chosen out. In general tank construction chooses pressure vessels in their dimensions and in their wall thicknesses so that the behavior towards the pressure load is optimal. As a result, most people get there Versions on cylindrical or spherical containers Containers that also have the advantage that they are include the largest volume with the least amount of material.
Bei Anwendungsfällen, wo jedoch räumliche Begrenzungen vorliegen, kann man auf diese "idealen Formen" von Behältern nicht zurückgreifen, sondern man muss als Randbedingungen äußere Begrenzungen berücksichtigen, über die man mit dem Behälter nicht hinausgehen kann oder die dazu führen würden, dass nur relativ kleine Behälter in diesen umgrenzten Raum hineinpassen könnten, was dann nun wiederum zu Kapazitätsproblemen führt. Rein von Räumlichkeiten und von dem eingeschlossenen Volumen her wären daher Behälter vorteilhaft, die sich eng an die äußeren Begrenzungen anlegen oder deren Teile sogar Teile der äußeren Begrenzung des Gerätes selbst bilden. Ein solcher Behälter trägt jedoch den Nachteil in sich, dass er kaum mit den üblicherweise zur Verfügung stehenden Verfahren hergestellt werden kann, was zu einer relativ teuren Herstellung führt. Wenn man dann noch die relativ hohen Druckbeanspruchungen berücksichtigt, kommen nur Metallblech-Behälter in Frage, was jedoch dazu führt, dass komplizierte Schweißvorgänge erforderlich sind, die nicht nur die Fertigung erschweren, sondern auch zu Korrosionserscheinungen führen können, wenn der Schweißvorgang nicht einwandfrei ausgeführt werden kann, was wiederum durch kompliziert gelegte Schweißnähte bewirkt wird. For use cases where there are spatial limitations can be found on these "ideal forms" of containers not fall back, but you have to as a boundary condition take into account external limits, with which you can use the Container cannot go out or that would cause that only relatively small containers in this confined space could fit in, which in turn leads to capacity problems leads. Purely from premises and from that enclosed volume, containers would therefore be advantageous, who are close to the outer borders or their Parts even parts of the outer boundary of the device itself form. However, such a container has the disadvantage of himself that he is barely available with the usual standing process can be produced, resulting in a leads to relatively expensive production. If you add that relatively high pressure loads are only considered Sheet metal containers in question, which however leads to that complicated welding processes are required, which not only complicate the manufacture, but also to corrosion can lead if the welding process does not can be executed properly, which in turn by complicated welds is caused.
Ideal wäre ein Behälter, der sich ganz eng an die äußeren vorgegebenen räumlichen Begrenzungen hält, leicht herzustellen ist und dennoch im Hinblick auf seine Druckbelastung höchste Anforderungen erfüllt. Dies ist Aufgabe der vorliegenden Erfindung.The ideal would be a container that is very close to the outside holds predetermined spatial limits, easy to manufacture is the highest in terms of its pressure load Requirements fulfilled. This is the task of the present Invention.
Bei der vorliegenden Erfindung wird für den vorgesehenen Einsatzzweck zunächst einmal die äußerste räumliche Begrenzung ermittelt und diese als äußere Formbegrenzung zur Herstellung des eigentlichen Druckbehälters herangezogen. Mit Hilfe relativ einfacher Mittel kann eine Form aus Metallteilen hergestellt werden, die weder hohen Temperaturen bei dem später erfolgenden Formvorgang standhalten muss noch irgendwelche Druckbelastung bei diesem Formvorgang aushalten muss. Liegt nun diese Vorform vor, wird sie beim Rotationsverfahren in einen Manipulator eingehängt, der gezielt solche räumliche Bewegungen durchführen kann, die es ermöglichen, dass praktisch jeder Begrenzungspunkt der Vorform zeitweilig die unterste geodätische Höhe einnimmt. In die Form wird pulverförmiger Kunststoff getan und durch Erhitzen der Form bei den vorangehend geschilderten Bewegungen schmilzt von der Oberfläche der Vorform her der Kunststoff an und bildet so die endgültige Behälterform, die die oben genanten Bedingungen erfüllt, d.h. die Form stimmt mit den vorgesehenen äußeren Begrenzungen überein, die Wandung ist so dick ausgeführt, dass hohen Drücken Widerstand entgegengesetzt werden kann, seien es Über- oder Unterdrücke und schließlich sind keine Korrosions- oder Zersetzungsvorgänge zu erwarten, wenn das gewählte Pulver bzw. das Material des Pulvers dem späteren Einsatzzweck entsprechend ausgewählt wird.In the present invention, the intended First of all, the ultimate spatial limitation determined and this as an outer shape limitation for manufacture the actual pressure vessel used. With help A relatively simple means can be a mold made of metal parts are produced, which are neither high temperatures at the must withstand the molding process that occurs later endure any pressure load during this molding process got to. If this preform is now available, it will be used for Rotation method hooked into a manipulator that can deliberately perform such spatial movements that it allow practically every boundary point of the preform temporarily occupies the lowest geodetic height. In the form powdered plastic is done and by heating the The shape of the movements described above melts from the plastic on the surface of the preform and thus forms the final container shape that meets the above conditions fulfilled, i.e. the shape matches the intended exterior Limits match, the wall is so thick that high pressure resistance can be opposed, be it Overpressure or underpressure and finally there are no corrosion or decomposition is expected when the chosen powder or the material of the powder for later use is selected accordingly.
Als Einsetzzweck eines solchen Behälters sei der Zwischenbehälter einer Vakuumtoilette genannt. In diesem Zwischenbehälter wird zum Entleeren der Schüssel des Klosetts ein Unterdruck erzeugt, so dass die abzufördernde Masse angesaugt werden kann. Um die angesaugte Masse dann in den endgültigen Aufnahmebehälter zu überführen, wird ein Druck auf den Innenraum des Zwischenbehälters ausgeübt, so dass innerhalb kürzester Zeit die Ablaufmasse weggefördert werden kann.The intermediate container is the intended use of such a container called a vacuum toilet. In this intermediate container is used to empty the bowl of the toilet Vacuum generated, so that the mass to be removed is sucked in can be. To the sucked mass then in the final Transferring receptacles will put pressure on the Interior of the intermediate container exercised so that inside the drainage mass can be conveyed away in the shortest possible time.
Als Material, das insbesondere fäkalienbeständig ist, kann Polyäthylen herangezogen werden. Gerade bei Toiletten ist die räumliche Umgrenzung für den Zwischenbehälter von besonderer Bedeutung, da dieser Zwischenbehälter im sog. Sitz der Toilette, d.h. unterhalb des Klosettdeckels und unterhalb der Schüssel untergebracht werden muss. Von der Größe her gesehen sind hier erhebliche Begrenzungen vorgegeben, wobei die Drücke relativ hoch sein können. Um auch noch eine vernünftig kurze Förderzeit und auch eine sichere Förderung der Ablaufmasse sicherzustellen, muss der Zwischenbehälter hinsichtlich seines Volumens auch eine ausreichende Größe haben.As a material that is particularly resistant to faeces Polyethylene can be used. This is particularly the case with toilets spatial boundary for the intermediate container of special Meaning, since this intermediate container in the so-called Toilet, i.e. below the toilet lid and below the Bowl must be accommodated. Seen in size there are considerable limits, the pressures can be relatively high. To make a reasonably short one Funding time and also a safe funding of the drainage mass ensure the intermediate container with regard to its Volume also have a sufficient size.
Bei einem solchen Zwischenbehälter können Arbeitsstücke von -0,8 bis 1,4 bar bewältigt werden, wobei Wanddicken von 8 mm, Rundungsradien von über 16 mm bei einem Volumen von 51 eingehalten werden können.With such an intermediate container, workpieces from -0.8 to 1.4 bar can be managed, with wall thicknesses of 8 mm, Rounding radii of over 16 mm with a volume of 51 can be met.
Die Erfindung wird nachstehend anhand der Zeichnungen beispielsweise erläutert.The invention is described below with reference to the drawings for example explained.
Es zeigen:
In Fig. 1 ist der Einlaß und der Auslaß eines Zwischenbehälters als beispielhafte Ausführungsform der Erfindung bezeichnet. Die Außenkonturen des Behälters sind so ausgestaltet, daß der Zwischenbehälter eng in den Raum paßt, den die Sitzverkleidung einer Toilette und andere dort vorhandene Aggregate zuläßt.In Fig. 1, the inlet and outlet are one Intermediate container as an exemplary embodiment of the Designated invention. The outer contours of the container are like this designed so that the intermediate container fits tightly into the room, the seat cover of a toilet and others there allows existing aggregates.
