Description

Die Erfindung betrifft eine Vorrichtung zur Entnahme von hochreinen Flüssigkeiten, insbesondere von hochreinen flüssigen Chemikalien aus Gebinden unter weitgehender Vermeidung von Partikelkontamination.The invention relates to a device for removing high-purity liquids, in particular high-purity liquid chemicals from containers while largely avoiding particle contamination.

Bei der Entnahme von hochreinen Flüssigkeiten, wie organische Lösemittel, Säuren und Laugen, die unter anderem für die Herstellung von Arzneimitteln, polymeren optischen Fasern, optischen Speichern oder hochintegrierten Halbleiterbausteinen notwendig sind, aus Transportgebinden darf die Qualität der hochreinen Flüssigkeit nicht in Frage gestellt werden. Das heißt, neben der chemischen muß auch die Partikelkontamination weitgehend ausgeschlossen werden. Bei der Entnahmevorrichtung sind daher aufeinandergleitende Teile, Totvolumina und die Zufuhr von kontaminierten Belüftungsmedien zu vermeiden.When removing high-purity liquids, such as organic solvents, acids and alkalis, which are necessary for the manufacture of pharmaceuticals, polymer optical fibers, optical memories or highly integrated semiconductor components, from transport containers, the quality of the high-purity liquid must not be questioned. This means that in addition to chemical, particle contamination must also be largely excluded. In the removal device, therefore, parts sliding on one another, dead volumes and the supply of contaminated ventilation media must be avoided.

Die Erfindung löst die Aufgabe durch eine Vorrichtung, die dadurch gekennzeichnet ist, daß die Vorrichtung besteht

  • a) aus einer Anschlußplatte mit drei Bohrungen, von denen zwei Bohrungen jeweils einen Anschlußstutzen für Steigrohre durchdringen und
  • b) einer Kopfplatte mit einem integrierten Ventilkörper zur Aufnahme von mindestens zwei Ventilköpfen, wobei die Kopfplatte drei zur Anschlußplatte kongruente Bohrungen aufweist, von der sich eine durch den Ventilkörper erstreckt und die beiden anderen Bohrungen einerseits enden in Rohrstutzen, die in die Bohrungen der Anschlußplatte hineinragen und andererseits in Kanälen für die hochreinen Flüssigkeiten, die im Ventilkörper angeordnet und durch die Ventilköpfe unterbrochen sind.
The invention solves the problem by a device which is characterized in that the device exists
  • a) from a connection plate with three holes, two of which each penetrate a connecting piece for risers and
  • b) a head plate with an integrated valve body for receiving at least two valve heads, the head plate having three holes congruent to the connection plate, one of which extends through the valve body and the other two holes on the one hand end in pipe sockets which protrude into the holes in the connection plate and on the other hand in channels for the high-purity liquids, which are arranged in the valve body and interrupted by the valve heads.

Eine der Bohrungen kann zentral und die beiden anderen Bohrungen spiegelbildlich zur zentralen Bohrung angeordnet sein.One of the holes can be arranged centrally and the other two holes can be arranged in mirror image to the central hole.

Der Ventilkörper kann mit zwei weiteren Kanälen versehen sein, die über zwei zusätzliche Ventilköpfe mit dem Kanalsystem für die hochreinen Flüssigkeiten in Verbindung stehen. Die Anschlußplatte kann als Matrize für die Kopfplatte ausgebildet sein und beide Platten können Einrichtungen zum Verbinden miteinander aufweisen. In den mit Rohrstutzen versehenen Bohrungen der Kopfplatte können Leiteinrichtungen wie Stifte oder Röhrchen angeordnet sein.The valve body can be provided with two further channels which are connected to the channel system for the high-purity liquids via two additional valve heads. The connection plate can be designed as a matrix for the head plate and both plates can have devices for connecting to one another. Guide devices such as pins or small tubes can be arranged in the bores of the head plate provided with pipe sockets.

Die Vorteile der Erfindung sind im wesentlichen darin zu sehen, daß beim Abnehmen der Kopfplatte die in den mit Rohrstutzen versehenen Bohrungen zurückbleibenden kleinen Flüssigkeitsvolumen zwangsläufig und vollständig in das Gebinde zurücklaufen. Das Spülen des Entnahmesystems ist ohne Trennen der Kopfplatte von der Anschlußplatte möglich. Die Vorrichtung ist totvolumenarm; die Ausbildung von Partikelnestern in den chemikalienführenden Leitungen und Bohrungen wird verhindert. Die Konstruktion des Ventilkörpers, der in der Kopfplatte integriert ist, in Verbindung mit der Verwendung von Membranventilköpfen ermöglicht Schaltvorgänge, die nur wenige Partikel erzeugen.The advantages of the invention can be seen essentially in the fact that when the head plate is removed, the small liquid volumes remaining in the bores provided with pipe sockets inevitably and completely run back into the container. The removal system can be flushed without separating the top plate from the connection plate. The device has a low dead volume; the formation of particle nests in the chemical-carrying lines and bores is prevented. The construction of the valve body, which is integrated in the head plate, in conjunction with the use of diaphragm valve heads, enables switching processes that produce only a few particles.

Im folgenden wird die Erfindung anhand von lediglich einen Ausführungsweg darstellenden Zeichnungen näher erläutert. Es zeigt

  • Figur 1 die Anschlußplatte in Draufsicht,
  • Figur 2 die Entnahmevorrichtung teilweise geschnitten,
  • Figur 3 eine Ansicht der Kopfplatte,
  • Figur 4 den Schnitt III-III der Figur 3 und
  • Figur 5 den Schnitt IV-IV der Figur 4.
The invention is explained in more detail below with the aid of drawings which illustrate only one embodiment. It shows
  • 1 shows the connection plate in plan view,
  • FIG. 2 shows the removal device partially cut,
  • FIG. 3 shows a view of the head plate,
  • Figure 4 shows the section III-III of Figure 3 and
  • 5 shows the section IV-IV of Figure 4.

Die Entnahmevorrichtung besteht aus einer Anschlußplatte 4, die mit einer Überwurfmutter 21 oder dergleichen an der Füll- und Entnahmeöffnung 1 eines Gebindes befestigt werden kann. 22 deutet die Dichtung zwischen Anschlußplatte 4 und Öffnung 1 an. Die Anschlußplatte 4 ist mit einer durchgehenden zentralen Bohrung 7 versehen, zu der spiegelbildlich zwei Bohrungen 5, 6 angeordnet sind, die jeweils einen Anschlußstutzen 8 für die in das Gebinde ragenden Steigrohre (nicht dargestellt) durchdringen. Die Anschlußplatte 4 ist als Matrize für die Kopfplatte 9 ausgebildet. Sie kann Ausnehmungen 27, 28 aufweisen, die konzentrisch (27) um die Zentralbohrung 7 bzw. (28) um die Bohrungen 5, 6 angeordnet sind und die die Kopfplatte 9 mit den zylinderförmigen Bolzen 19, 20 aufnehmen. In die Ausnehmungen 28 münden die Bohrungen 5, 6. Die Kopfplatte 9 weist einen integrierten Ventilkörper 23 auf, der mit mindestens zwei Ventilsitzen 16, 17 zur Aufnahme von Ventilköpfen 2, 3 versehen ist. Die Kopfplatte 9 weist eine zentrale Bohrung 12 auf, die sich durch den Ventilkörper 23 erstreckt und mit der zentralen Bohrung 7 der Anschlußplatte 4 die Be- und Entlüftungsleitung für das Gebinde bildet. Zur zentralen Bohrung 12 sind spiegelbildlich zwei denzentrale Bohrungen 10, 11 angeordnet, die einerseits enden in Rohrstutzen 29, 30, die in die Bohrungen 5, 6 der Anschlußplatte 4 hineinragen, und andererseits in Kanälen 31, 32, 33, 34 für die hochreinen Flüssigkeiten, die im Ventilkörper 23 angeordnet und durch die Ventilköpfe 2, 3 unterbrochen sind. Die Kopfplatte kann gegen die Anschlußplatte mit Dichtungen 24, 25, 26 abgedichtet sein. Zum Spülen der Entnahmevorrichtung kann der Ventilkörper 23 mit Kanälen 13, 14 zum Heranführen von Spülflüssigkeiten versehen sein, die in zwei weiteren Ventilsitzen 37, 38 enden und über zwei Ventilköpfe (nicht dargestellt) mit den Kanälen 33, 34 in Verbindung stehen. Die Kanäle 33, 34 sind mit Leitungsanschlüssen 35, 36 versehen. Die in die Bohrungen 5, 6 ragenden Enden der Rohrstutzen 29, 30 können angeschrägt sein, was ein Leerlaufen der Bohrungen 10, 11 beim Trennen von Anschlußplatte 4 und Kopfplatte 9 beschleunigt. Eine weitere Beschleunigung des Leerlaufens wird durch Anordnen von Leiteinrichtungen 18, wie z.B. Stifte erreicht. 15 deutet den Überwurfring zum Verbinden von Kopf- und Anschlußplatte, 39 die Nocken der Anschlußplatte 4 in die der Überwurfring 15 eingreift und 40 Positioniernocken für die Kopfplatte 9 an.The removal device consists of a connection plate 4, which can be attached to the filling and removal opening 1 of a container with a union nut 21 or the like. 22 indicates the seal between the connecting plate 4 and opening 1. The connection plate 4 is provided with a continuous central bore 7, to which two bores 5, 6 are arranged in mirror image, each of which penetrates a connection piece 8 for the riser tubes (not shown) projecting into the container. The connection plate 4 is designed as a matrix for the head plate 9. It can have recesses 27, 28 which are arranged concentrically (27) around the central bore 7 or (28) around the bores 5, 6 and which receive the head plate 9 with the cylindrical bolts 19, 20. The bores 5, 6 open into the recesses 28. The head plate 9 has an integrated valve body 23 which is provided with at least two valve seats 16, 17 for receiving valve heads 2, 3. The top plate 9 has a central bore 12 which extends through the valve body 23 and forms the ventilation line for the container with the central bore 7 of the connection plate 4. The central bore 12 is a mirror image of two central bores 10, 11, which end on the one hand in pipe sockets 29, 30 which protrude into the bores 5, 6 of the connecting plate 4, and on the other hand in channels 31, 32, 33, 34 for the high-purity liquids , which are arranged in the valve body 23 and interrupted by the valve heads 2, 3. The top plate can be sealed against the connection plate with seals 24, 25, 26. For rinsing the removal device, the valve body 23 can be provided with channels 13, 14 for introducing rinsing liquids which end in two further valve seats 37, 38 and are connected to the channels 33, 34 via two valve heads (not shown). The channels 33, 34 are provided with line connections 35, 36. The ends of the projecting into the bores 5, 6 Pipe sockets 29, 30 can be chamfered, which accelerates an empty running of the bores 10, 11 when separating the connecting plate 4 and the top plate 9. A further acceleration of idling is achieved by arranging guide devices 18, such as pins. 15 indicates the coupling ring for connecting the head and connecting plate, 39 the cams of the connecting plate 4 into which the coupling ring 15 engages and 40 positioning cams for the head plate 9.

Um zu gewährleisten, daß nur Gebinde gleichen Inhalts an die Entnahmevorrichtung angeschlossen werden können und für den Fall, daß die Anschlußplatte 4 an der Füll- und Entnahmeöffnung 1 des Gebindes verbleiben soll, kann die Anschlußplatte 4 mit einer Kodierung (Bohrungen) versehen sein, die mit entsprechenden Mitteln an der Kopfplatte 9 korreliert (nicht dargestellt).In order to ensure that only containers of the same content can be connected to the removal device and in the event that the connection plate 4 is to remain at the filling and removal opening 1 of the container, the connection plate 4 can be provided with a coding (holes) which correlated with corresponding means on the head plate 9 (not shown).
