Abstract

An impeller for aseptic purposes which is rotatable by inductive drive means in a predetermined direction within a vessel for stirring and mixing sterile fluids. The impeller (10) comprises a plurality of radially extending stirring blades (15) on an outer surface of the impeller and bearing means on an inner surface of said impeller for rotatably mounting the impeller on the vessel wall. The impeller is further provided with through-flow passages which outwardly extend from the inside of the impeller in a direction away from an axis of rotation, through orifices (25, 26) which are situated on the outer sr-face of the impeller immediately adjacent each blade (15), seen in said direction of rotation, so that cleaning fluid can be sucked through the passages due to a low pressure region occurring behind each blade.

Description

:f Û fi: lf. Il gr] . : f Û fi: lf. Il gr].

,C¿3 2 Enligt ett fördelaktigt utföringsexempel av uppfinningen omfattar lagringsorganen en axeltapp som är centralt placerad på en ändvägg, vilken avgränsar en från området av tankens botten inåt riktad cylindrisk försänkning i tankväggen.According to an advantageous embodiment of the invention, the storage means comprise a shaft pin which is centrally located on an end wall, which delimits a cylindrical depression in the tank wall directed inwards from the area of the bottom of the tank.

Lâmpligen omges den cylindriska försänkningen av ett periferi- ellt parti, med ett visst litet spaltavstànd som möjliggör passage av rengöringsfluid mellan den cylindriska försänk- ningen och omrörarens periferiella parti.Suitably the cylindrical recess is surrounded by a peripheral portion, with a certain small gap distance which enables the passage of cleaning fluid between the cylindrical recess and the peripheral portion of the stirrer.

De ovan nämnda och ytterligare egenskaper hos uppfinningen kommer att beskrivas mer detaljerat i det följande, med hänvisning till den bifogade ritningen, på vilken Fig. 1 visar en omrörare enligt uppfinningen i en planvy, Fig. 2 är en delvis sektionerad sidovy av omröraren inklusive dess drivanordning, och Fig. 3 är ett snitt längs linjen III-III i Fig. 1.The above-mentioned and further features of the invention will be described in more detail in the following, with reference to the accompanying drawing, in which Fig. 1 shows a stirrer according to the invention in a plan view, Fig. 2 is a partially sectioned side view of the stirrer including its drive device, and Fig. 3 is a section along the line III-III in Fig. 1.

Den pà ritningen visade omröraren 10 är placerad i ett blandningskärl, vars bottenvägg 11 framträder i fig. 2. Detta kärl är avsett för användning i en stor processanläggning, t.ex. för framställning av läkemedel, och är försett med ett antal inlopp, utlopp och reglerventiler. Olika sterila vätskor matas till kärlet, där de blandas samman medelst omröraren 10, varefter den resulterande blandningen tappas av fràn kärlet.The stirrer 10 shown in the drawing is placed in a mixing vessel, the bottom wall 11 of which appears in Fig. 2. This vessel is intended for use in a large process plant, e.g. for the manufacture of medicaments, and is provided with a number of inlets, outlets and control valves. Various sterile liquids are fed to the vessel, where they are mixed together by means of the stirrer 10, after which the resulting mixture is drained from the vessel.

Omrörarens lagrings- och drivorgan visas i Fig. 2 och omfattar en från tankens botten inåt riktad, cylindrisk försänkning 12 i tankväggen ll, vilken försänkning är insvetsad på så sätt att inga öppningar eller genomföringar förekommer i denna del av tankväggen. Omröraren 10 är lagrad medelst en bussning l0a på en axeltapp 13 som är centralt placerad pâ en ändvägg 14, vilken avgränsar den cylindriska försänkningen 12. 463 '_7350 3 Omröraren 10 är liksom kärlvâggen 11 huvudsakligen tillverkad av rostfritt syrafast stål, med ett antal svängda blad 15 och en central lyftring 16. Omröraren uppvisar ett periferiellt parti 17 som omger den cylindriska försänkningen 12 och inrymmer ett antal permanentmagneter 18 som står i induktiv förbindelse med ett motsvarande antal permanentmagneter 19, vilka är placerade i en rotor 20. Denna rotor är avsedd att drivas i pilens 21 (se Fig. 1) riktning av en konventionell, icke visad elmotor, varvid den försänkningen omgivande omröraren 10 dras med.The storage and drive means of the agitator are shown in Fig. 2 and comprise a cylindrical recess 12 directed inwards from the bottom of the tank into the tank wall 11, which recess is welded in such a way that no openings or penetrations occur in this part of the tank wall. The stirrer 10 is mounted by means of a bushing 10a on a shaft pin 13 which is centrally located on an end wall 14, which delimits the cylindrical recess 12. The stirrer 10, like the vessel wall 11, is mainly made of stainless acid-resistant steel, with a number of curved blades. 15 and a central lifting ring 16. The stirrer has a peripheral portion 17 which surrounds the cylindrical recess 12 and houses a number of permanent magnets 18 which are in inductive communication with a corresponding number of permanent magnets 19, which are placed in a rotor 20. This rotor is intended to driven in the direction of the arrow 21 (see Fig. 1) by a conventional electric motor, not shown, the agitator 10 surrounding the recess being pulled along.

Av Fig. 3 framgår att omröraren är försedd med genomström- ningskanaler 22, 23, vilka sträcker sig från insidan av omröraren 10, i riktning utåt fràn en rotationsaxel 24 till mynningar 25 resp. 26. dessa är placerade på utsidan av omröraren närmast framförvarande blad 15, sett i pilens 21 rotationsriktning. Genom denna anordning kommer rengörings- fluid att sugas via kanalerna, med hjälp av det pà bladbak- sidan verkande undertrycket. På detta sätt kan rengörings- fluiden under omrörarens rotation dras förbi försänkningen 12 samt axeltappen 13, varefter fluiden kan passera ut ur omrör- aren via de huvudsakligen radiellt riktade kanalerna 22, 23.From Fig. 3 it can be seen that the stirrer is provided with flow channels 22, 23, which extend from the inside of the stirrer 10, in the outward direction from an axis of rotation 24 to the mouths 25 and 23, respectively. 26. these are located on the outside of the stirrer closest to the blade 15, seen in the direction of rotation of the arrow 21. Through this device, cleaning fluid will be sucked through the channels, by means of the negative pressure acting on the blade back. In this way, during the rotation of the stirrer, the cleaning fluid can be drawn past the recess 12 and the shaft pin 13, after which the fluid can pass out of the stirrer via the substantially radially directed channels 22, 23.

Uppfinningen är ej begränsad till det ovan beskrivna ut- föringsexemplet, utan flera varianter är tänkbara inom ramen för efterföljande krav. Exempelvis kan kanalerna och mynningarna vara fler eller färre till antalet. Organen för omrörarens drivning kan vara annorlunda utformade.The invention is not limited to the exemplary embodiment described above, but several variants are conceivable within the scope of the following claims. For example, the channels and estuaries may be more or fewer in number. The means for driving the agitator may be differently designed.
