Mit derartigen Vorrichtungen des Standes der Technik werden Reinraumbedingungen innerhalb einer freistehenden Schutzverkleidung einer industriellen Anlage gewährleistet. Jedoch besteht das Problem, dass derartige geschlossene Anlagen üblicherweise nicht in einer Umgebung mit Reinraumbedingungen aufgestellt sind. Im Betrieb oder zur Wartung der Anlagen ist jedoch wenigstens gelegentlich ein Eingriff in das Innere der Schutzverkleidung notwendig, sodass die Schutzverkleidung der Anlage, üblicherweise an einer dafür vorgesehenen Abdeckung oder Tür geöffnet werden muss.With such devices of the prior art, clean room conditions are guaranteed within a free-standing protective covering of an industrial plant. However, there is the problem that such closed systems are usually not set up in an environment with clean room conditions. During operation or for maintenance of the systems, however, intervention into the interior of the protective casing is at least occasionally necessary, so that the protective casing of the system usually has to be opened at a cover or door provided for this purpose.

Dabei kommt es jedoch regelmäßig zu einer Verunreinigung des Inneren der Anlage durch den Eintrag von Schmutzpartikeln aus der unmittelbaren Umgebung der die Anlage umgebenden Schutzverkleidung, was eine aufwändige Reinigung oder sogar eine Unterbrechung des Betriebs der Anlage notwendig macht. Alternativ müssen aufwändige Vorrichtungen geschaffen werden, um einen Eingriff in eine Anlage im Betrieb zu ermöglichen, was mit erhöhten Herstellungs- und Betriebskosten verbunden ist und einen erhöhten Raumbedarf der Anlagen zur Folge hat.However, this regularly leads to contamination of the interior of the system due to the ingress of dirt particles from the immediate vicinity of the protective covering surrounding the system, which necessitates complex cleaning or even an interruption in the operation of the system. Alternatively, complex devices have to be created in order to allow intervention in a system during operation, which is associated with increased production and operating costs and results in an increased space requirement for the systems.

Darüber hinaus ist alternativ oder zusätzlich häufig auch eine Belüftung der unmittelbaren Umgebung einer solchen Anlage innerhalb der Einhausung erwünscht, um von der Anlage freigesetzte Chemikalien, Schmutzpartikel und/oder Schadstoffe zu entfernen.In addition, as an alternative or in addition, ventilation of the immediate surroundings of such a system within the housing is often desirable in order to remove chemicals, dirt particles and/or pollutants released by the system.

Der Erfindung liegt daher die Aufgabe zu Grunde, eine Einhausung sowie ein entsprechendes Verfahren bereitzustellen, mittels denen die Luftqualität in der unmittelbaren Umgebung einer eingehausten Anlage verbessert werden kann und dabei die Zugänglichkeit zu einer Anlage innerhalb der Einhausung, insbesondere mit einer Steril- oder Reinraumatmosphäre, in einfacher Weise verbessert wird und bei denen zugleich keine wesentlich erhöhten Herstellungs- und Betriebskosten auftreten sowie die keinen wesentlich erhöhten Raumbedarf innerhalb oder außerhalb der Einhausung aufweisen.The invention is therefore based on the object of providing an enclosure and a corresponding method by means of which the air quality in the immediate vicinity of an enclosed system can be improved and the accessibility to a system within the enclosure, in particular with a Sterile or clean room atmosphere is improved in a simple manner and in which at the same time no significantly increased manufacturing and operating costs occur and have no significantly increased space requirements inside or outside the enclosure.

Vorteilhafte Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben.The object is achieved according to the invention by a housing according to claim 1 and a method according to claim 14.

Diese verbesserte Luftqualität an der Außenseite der Einhausung, insbesondere im Bereich von Zugängen in das Innere der Einhausung, ermöglicht dabei einen Zugang zur Einhausung bzw. ein kurzzeitiges Öffnen der Einhausung mit einem deutlich gesenkten Risiko einer Verunreinigung des Inneren bzw. der darin befindlichen Anlage. Darüber hinaus kann die Luftqualität in der Umgebung der Anlage, insbesondere dabei auch im Inneren der Einhausung, im Hinblick auf von der Anlage freigesetzte Chemikalien, Schmutzpartikel und/oder Schadstoffe in einfacher Weise verbessert werden.With the at least one, preferably several, gas outlets arranged on the outside and preferably also on the inside of the housing, the invention enables gas to be supplied to the immediate inner or outer surroundings of the housing in a particularly simple, space-saving and cost-effective manner, whereby particularly an effective improvement in the air quality and in particular the air purity in the immediate vicinity of an enclosed facility is achieved.

Eine in Fig. 1a dargestellte Einhausung 1 weist einen Tragrahmen 2 sowie daran angeordnete Abdeckelemente 10 auf. Die Einhausung 1 ist dabei freistehend gebildet, wobei die Formstabilität mittels des Tragrahmens 2 erreicht wird. Die Abdeckelemente 10 verschließen die Einhausung 1 soweit luftdicht, dass darin eine Steril- bzw. Reinraumatmosphäre hergestellt werden kann, sodass in der Einhausung 1 beispielsweise eine Anlage zum Herstellen oder Befüllen von Lebensmittelverpackungen angeordnet werden kann.one inside Fig. 1a The housing 1 shown has a support frame 2 and cover elements 10 arranged thereon. The housing 1 is formed in a free-standing manner, with the dimensional stability being achieved by means of the support frame 2 . The cover elements 10 close the housing 1 in an airtight manner to such an extent that a sterile or clean room atmosphere can be created therein, so that a system for producing or filling food packaging, for example, can be arranged in the housing 1 .

Die Abdeckelemente 10 der Einhausung 1 sind dabei zumindest teilweise als öffenbare Türen gebildet. Zusätzlich kann die Einhausung 1 auch Bedienfelder 11 aufweisen, die insbesondere an der Außenseite der Einhausung 1 angeordnet sind und zur Bedienung der Einhausung 1 oder einer Anlage innerhalb der Einhausung 1 dienen (siehe Fig. 1a). Um die Einhausung 1 vom darunterliegenden Boden beabstandet anzuordnen und darüber hinaus eine Anpassung an Unebenheiten des Bodens zu ermöglichen, sind an der Unterseite der Einhausung 1 mehrere höhenverstellbare Fußelemente 9 angeordnet.The cover elements 10 of the housing 1 are at least partially formed as openable doors. In addition, the housing 1 can also have control panels 11, which are arranged in particular on the outside of the housing 1 and are used to operate the housing 1 or a system within the housing 1 (see FIG Fig. 1a ). In order to arrange the housing 1 at a distance from the floor below and also to enable an adjustment to unevenness in the floor, several height-adjustable foot elements 9 are arranged on the underside of the housing 1 .

Der Tragrahmen 2 weist wenigstens einem waagerechten Rahmenelement 6 und mehreren, am Rahmenelement 6 angeordneten, senkrecht verlaufenden Trägern 7 auf (siehe Fig. 1a und 1b). Dabei sind die Träger 7 jeweils derart an einem Rahmenelement 6 festgelegt, dass Gas von dem Rahmenelement 6 in den Träger 7 strömen kann. An der Unterseite jedes Trägers 7 ist eines der Fußelemente 9 angeordnet (siehe Fig. 1c).The support frame 2 has at least one horizontal frame element 6 and a plurality of vertically running supports 7 arranged on the frame element 6 (see FIG Fig. 1a and 1b ). The carriers 7 are each fixed to a frame element 6 in such a way that gas can flow from the frame element 6 into the carrier 7 . One of the foot elements 9 is arranged on the underside of each carrier 7 (see FIG 1c ).

Bei der in den Fig. 1 dargestellten Ausführung der Einhausung 1 weist wenigstens einer der Träger 7 bodennah einen aus mehreren übereinander angeordneten Öffnungen gebildeten Gasauslass 5 auf, aus denen ein durch den Tragrahmen 2 geleitetes Gas ausströmen kann und dabei die Qualität der Luft in der unmittelbaren Umgebung der Einhausung 1 verbessert, sodass das Risiko der Verunreinigung des Inneren der Einhausung 1, insbesondere bei einem kurzzeitigen Öffnen eines der Abdeckelemente 10 deutlich reduziert werden kann.At the in the 1 The embodiment of the housing 1 shown in the illustration has at least one of the supports 7 close to the ground with a gas outlet 5 formed from several openings arranged one above the other, from which a gas guided through the support frame 2 can flow out, thereby improving the quality of the air in the immediate vicinity of the housing 1, so that the risk of internal contamination of the housing 1, in particular when one of the cover elements 10 is briefly opened.

Das Innere wenigstens eines Teils des Tragrahmens 2 bildet dabei ein Gasleitungssystem 3, mittels dem Gas von einer zentralen Gaszuleitung 4 zu wenigstens einem Gasauslass 5, bevorzugt zugleich zu mehreren an unterschiedlichen Positionen des Tragrahmens 2 angeordneten Gasauslässen 5 geleitet wird. Bei der in Fig. 1 dargestellten Vorderseite der Einhausung 1 sind beispielsweise an dem Rahmenelement 6 an der Oberseite des Tragrahmens 2 sowie an der Unterseite mehrerer der Träger 7 jeweils ein Gasauslass 5 angeordnet.The interior of at least part of the support frame 2 forms a gas line system 3, by means of which gas is routed from a central gas supply line 4 to at least one gas outlet 5, preferably at the same time to a plurality of gas outlets 5 arranged at different positions on the support frame 2. At the in 1 On the front side of the housing 1 shown, a gas outlet 5 is arranged, for example, on the frame element 6 on the upper side of the support frame 2 and on the underside of several of the supports 7 .

Ein Abschnitt eines Tragrahmens 2 einer zweiten Ausführung einer Einhausung 1 ist in den Fig. 2 dargestellt. Dabei sind abermals mehrere Träger 7 mit einem Rahmenelement 6 derart verbunden, dass diese ein gemeinsames Gasleitungssystem 3 bilden. Während bei dieser Ausführung am Rahmenelement 6 keine Gasauslässe 5 angeordnet sind, weist jeder der Träger 7 im Bereich des unteren Endes einen einzelnen Gasauslass 5 in Form einer rechteckigen Öffnung auf. Die untere, auf den Boden zuweisende Seite 8 des Trägers 7 ist dabei gasdicht verschlossen, sodass das gesamte Gas durch die Gasauslässe 5 in Richtung der Außenseite der Einhausung 1 bodennah austritt. Die Zuleitung des Gases in das Gasleitungssystem 3 erfolgt durch einen einzigen, an dem Rahmenelement 6 angeordneten zentralen Gaszugang 4.A portion of a support frame 2 of a second embodiment of an enclosure 1 is in the 2 shown. In this case, several carriers 7 are again connected to a frame element 6 in such a way that they form a common gas line system 3 . While no gas outlets 5 are arranged on the frame element 6 in this embodiment, each of the carriers 7 has a single gas outlet 5 in the area of the lower end in the form of a rectangular opening. The lower side 8 of the carrier 7 pointing towards the floor is sealed in a gas-tight manner, so that all of the gas exits through the gas outlets 5 in the direction of the outside of the housing 1 near the floor. The gas is fed into the gas line system 3 through a single central gas inlet 4 arranged on the frame element 6.

Eine dritte Ausführung eines Teils eines Tragrahmens 2 für eine Einhausung 1 ist in Fig. 3 dargestellt, wobei sich diese Ausführung von der zweiten Ausführung maßgeblich dadurch unterscheidet, dass die Gasauslässe 5 nicht an einer zur Außenseite der Einhausung 1 weisenden Vorderseite der Träger 7, sondern an einer auf den Boden unter der Einhausung 1 weisenden Unterseite 8 der Träger 7 angeordnet sind. Der Gasaustritt erfolgt somit unmittelbar neben den ebenfalls an der Unterseite 8 der Träger 7 angeordneten Fußelementen 9. Dabei wird das Gas sowohl in das Innere der Einhausung 1 geleitet, um dort die Luftqualität in Hinblick auf von der Anlage in der Einhausung 1 freigesetzte Chemikalien und Partikel zu verbessern, als auch in die unmittelbare, äußere Umgebung der Einhausung, um dort befindliche Schmutzpartikel von der eingehausten Anlage weg zu leiten.A third embodiment of part of a support frame 2 for an enclosure 1 is in 3 shown, this embodiment differing significantly from the second embodiment in that the gas outlets 5 are not arranged on a front side of the carrier 7 pointing to the outside of the housing 1, but on an underside 8 of the carrier 7 pointing to the floor under the housing 1 . The gas escapes immediately next to the foot elements 9, which are also arranged on the underside 8 of the supports 7. The gas is guided into the interior of the housing 1 in order to improve the air quality there with regard to chemicals and particles released by the system in the housing 1 to improve than also in the immediate, external environment of the enclosure, in order to conduct dirt particles away from the enclosed system.

Bei einer vierten Ausführung eines Teils eines Tragrahmens 2 für eine Einhausung 1 sind jeweils drei Gasauslässe 5 übereinander an jedem der Träger 7 angeordnet (siehe Fig. 4a und 4b). Dabei ist jeder der Gasauslässe 5 als eine sich entlang der Längsachse des Trägers 7 erstreckende rechteckige Öffnung gebildet, wobei die Länge jedes Gasauslasses 5 etwa 20 % der Länge des Trägers 7 in dieser Richtung entspricht, sodass eine flächige und umfassende Belüftung des unmittelbaren Umfelds der Einhausung 1 erreicht werden kann. Die Unterseiten 8 der Träger 7 sind abermals geschlossen.In a fourth embodiment of part of a support frame 2 for a housing 1, three gas outlets 5 are arranged one above the other on each of the supports 7 (see FIG Figure 4a and 4b ). Each of the gas outlets 5 is formed as a rectangular opening extending along the longitudinal axis of the carrier 7, with the length of each gas outlet 5 corresponding to approximately 20% of the length of the carrier 7 in this direction, so that there is extensive and extensive ventilation of the immediate vicinity of the housing 1 can be achieved. The undersides 8 of the carriers 7 are closed again.

Auch bei einer fünften Ausführung einer Einhausung 1, von der ein Teil des Tragrahmens 2 in Fig. 5 dargestellt ist, ist auf jedem der Träger 7 ein sich über im Wesentlichen die gesamte Länge des Trägers 7 erstreckender, einzelner Gasauslass 5 in Form einer langgezogenen, rechteckigen Öffnung angeordnet.Also in a fifth embodiment of an enclosure 1, from which part of the support frame 2 in figure 5 is shown, a single gas outlet 5 in the form of an elongated, rectangular opening is arranged on each of the carriers 7 and extends essentially over the entire length of the carrier 7 .

Schließlich kann auch das Rahmenelement 6, zusätzlich zu weiteren Gasauslässen 5 oder ausschließlich, einen sich entlang der Länge des Rahmenelements 6 bzw. eines Bauteils des Rahmenelements 6 erstreckenden Gasauslass 5 aufweisen, wie es in Fig. 6 dargestellt ist.Finally, the frame element 6 can also have, in addition to further gas outlets 5 or exclusively, a gas outlet 5 extending along the length of the frame element 6 or a component of the frame element 6, as is shown in FIG 6 is shown.

Bei der erfindungsgemäßen Einhausung 1 können grundsätzlich beliebig viele Gasauslässe 5 an dem Tragrahmen 2 angeordnet sein und insbesondere können die Gasauslässe 5 mehrerer der zuvor dargestellten Ausführungen beliebig miteinander kombiniert werden. Besonders bevorzugt wird dabei beispielsweise Gasauslässe 5 im Bereich einer Öffnung oder eines öffenbaren Abdeckelements 10 sowohl an den benachbarten Trägern 7 als auch an wenigstens einem angrenzenden Rahmenelement 6 anzuordnen.In the case of the housing 1 according to the invention, any number of gas outlets 5 can in principle be arranged on the supporting frame 2 and in particular the gas outlets 5 of several of the previously illustrated embodiments can be combined with one another as desired. It is particularly preferred, for example, to arrange gas outlets 5 in the area of an opening or an openable cover element 10 both on the adjacent supports 7 and on at least one adjacent frame element 6 .
