Abstract

The double-conical casing includes a short connection chamber. Preferred features: The double cone alternatively includes a long connection chamber. It is filled 85%, 90% or more, with activated carbon.

Description

Die Erfindung betrifft ein fliegendes Filtersystem bestehend aus Aktivkohle zur Absorption von toxischen und/oder nicht-toxischen Monomer-Dämpfen und einem Kegelgehäuse, wobei das Kegelgehäuse die Form eines Doppelkegels besitzt, der aus zwei an ihren sich verjüngenden Enden miteinander verbundenen Kegeln gebildet wird.The invention relates to a flying filter system consisting of Activated carbon for the absorption of toxic and / or non-toxic Monomer vapors and a cone case, the Cone housing has the shape of a double cone that consists of two their tapered ends connected cones is formed.

Es ist bekannt, Dämpfe von Monomeren, insbesondere von toxischen Monomeren, zu befreien, indem diese Dämpfe durch ein Filtermedium mit hoher spezifischer Oberfläche, beispielsweise Aktivkohle, geleitet werden.It is known vapors from monomers, especially toxic Monomers to get rid of these vapors through a Filter medium with a high specific surface, for example Activated carbon.

Aus dem Stand der Technik sind stationäre und freie (oder fliegende) Filtersysteme bekannt, bei denen die Saug- bzw. Fließrichtung vorgegeben ist.State of the art are stationary and free (or flying) Filter systems known in which the suction or flow direction is specified.

Das fliegende Filtersystem hat die Form eines Kegels und wird z. B. als Kraftstofffilter für Ottomotoren eingesetzt. Der Nachteil dieser Filtersysteme besteht darin, daß sie nach Befüllung mit Aktivkohle bei ungünstiger Lageposition oder wenn der Filter in falscher Saugrichtung aufgesteckt wurde, unwirksam werden.The flying filter system has the shape of a cone and is used e.g. B. used as a fuel filter for gasoline engines. The disadvantage of this Filter systems is that after they are filled with activated carbon unfavorable position or if the filter is in the wrong position Suction direction has been plugged in, become ineffective.

Die DE-29 01 938 C2 beschreibt einen Strömungsmittelseparator, wobei die Halteeinrichtungen einen kegelstumpfförmigen Abschnitt des Gehäuses umfassen, so daß die Querschnittfläche des Adsorptionsmaterialbettes linear mit der Entfernung von dem ersten großen Abschnitt zum zweiten kleinen Abschnitt abnimmt, um auf diese Weise Änderungen der Strömungsgeschwindigkeit auszu­ gleichen.DE-29 01 938 C2 describes a fluid separator, the holding means having a frustoconical section of the housing so that the cross-sectional area of the Adsorbent bed linear with the distance from the first large section to the second small section decreases to this way to accommodate changes in flow velocity same.

Die DE-OS-35 29 641 beschreibt ein Filtergehäuse, daß die Form eines Doppelkegels hat, der dadurch entstanden ist, daß die Grundfläche von zwei Kegeln miteinander verbunden wurden.DE-OS-35 29 641 describes a filter housing that the shape of a double cone, which has arisen from the fact that the Base of two cones were connected to each other.

Aufgabe der vorliegenden Erfindung war es somit, ein fliegendes Filtersystem zu entwickeln, daß die bekannten Nachteile aus dem Stand der Technik vermeidet, also in der Praxis sowohl unabhängig von der Lageposition als auch von der Saugrichtung ist.The object of the present invention was therefore a flying Develop filter system that the known disadvantages from  Avoids state of the art, i.e. in practice both independently from the position as well as from the suction direction.

Diese Aufgabe wird durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. Vorteilhafte Ausführungsformen ergeben sich aus den Unteransprüchen.This task is characterized by the characteristics of the Claim 1 solved. Advantageous embodiments result from the subclaims.

Die Ausführungsformen A und B (siehe Fig. 1 und 2) sind in der Formgebung erfindungswesentlich. Für beide Ausführungen steht unabhängig von der Lageposition des Filters die absolute fehlerfreie Anwendung.The embodiments A and B (see FIGS. 1 and 2) are essential to the invention in terms of their shape. For both versions, the absolute error-free application is independent of the position of the filter.

Als Aktivkohle kann jede für diese Zwecke geeignete Aktivkohle eingesetzt werden.Any activated carbon suitable for this purpose can be used as activated carbon be used.

Ausführungsformen gemäß der Erfindung sind im folgenden anhand der Figuren beispielhaft näher beschrieben:Embodiments according to the invention are described below the figures are described in more detail by way of example:

Fig. 1 stellt das Filtersystem als Doppelkegel mit kurzer Verbindungskammer dar (in waagerechter Anordnung). Die Funktion ist bei einer Minderfüllung von max. 15% noch sicher, d. h. eine Aktivkohlefüllung von 85% ist ausreichend. Diese Ausführungsform ist kostengünstiger als die in Fig. 2 dargestellte Version. Sie wird deshalb bevorzugt eingesetzt. Fig. 1 shows the filter system as a double cone with a short connection chamber (in a horizontal arrangement). The function is only possible if the filling is less than max. 15% is still safe, ie an activated carbon filling of 85% is sufficient. This embodiment is less expensive than the version shown in FIG. 2. It is therefore preferred.

Fig. 2 stellt das Filtersystem als Doppelkegel mit langer Verbindungskammer dar (in waagerechter Anordnung). Die Funktion ist bei einer Minderfüllung von max. 10% noch sicher, d. h. eine Aktivkohlefüllung von 90% ist ausreichend. Fig. 2 shows the filter system as a double cone with a long connecting chamber (in a horizontal arrangement). The function is only possible if the filling is less than max. 10% still safe, ie an activated carbon filling of 90% is sufficient.

Fig. 3 Anordnung analog zu Fig. 1, jedoch in Schräglage. Fig. 3 arrangement analogous to Fig. 1, but in an inclined position.

Fig. 4 Anordnung analog zu Fig. 2, jedoch in Schräglage. Fig. 4 arrangement analogous to Fig. 2, but in an inclined position.

Das erfindungsgemäße Filtersystem findet bevorzugt Anwendung als Aktivkohlefilter beim Anmischen von Knochenzement, bei dem toxische Monomer-Dämpfe entstehen. Neben dem Einsatz in der Chirugie kann das Filtersystem genauso auch im nicht-medizinischen Bereich eingesetzt werden.The filter system according to the invention is preferably used as Activated carbon filter when mixing bone cement, in which toxic monomer vapors are generated. In addition to use in the The filter system can also be used in non-medical surgery Area can be used.
