Abstract

A drive device for an impeller (17) which is rotatably mounted within a vessel (11) for stirring and mixing sterile fluids. The drive device is rotatably mounted at an inwardly-directed cylindrical recess (15) in a bottom wall (16) of the vessel, the recess (15) being intended to receive the drive device. The impeller (17) includes a peripheral section (21) which surrounds the cylindrical recess (15). A stator (24) is fixedly secured in the recess (15), which stator includes a magnetisable iron core (25) and induction coils connectable to a 3-phase alternating current source. Inductively magnetisable elements 23 are located in the peripheral section (21) of the impeller (17) for generating a torque when the stator (24) is supplied with a 3-phase alternating current so that the impeller rotates in a predetermined direction.

Description

2 462 -834 Lämpligen upprätthálles ett litet spaltavstånd mellan den cylindriska försänkningen och omrörarens periferiparti. 2 462 -834 Preferably, a small gap distance is maintained between the cylindrical recess and the peripheral portion of the stirrer.

Enligt ytterligare ett fördelaktigt utföringsexempel av uppfinningen är de magnetiserbara elementen hermetiskt inneslutna i omröraren.According to a further advantageous embodiment of the invention, the magnetizable elements are hermetically enclosed in the stirrer.

De ovan nämnda och ytterligare egenskaper hos uppfinningen kommer att beskrivas mer detaljerat i det följande, med hänvis- ning till den bifogade ritningen, på vilken Fig. 1 I visar ett med drivanordning enligt uppfinningen utrustat blandningskärl i en perspektivvy, Fig. 2 är en delvis sektionerad sidovy av drivanordningen, och Fig. 3 visar en drivanordningen avsedd styrenhet.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. 11 shows a mixing vessel equipped with a drive device according to the invention in a perspective view, Fig. 2 is a partial sectioned side view of the drive device, and Fig. 3 shows a control unit intended for the drive device.

Det i Fig. 1 visade blandningskärlet omfattar ett pà fyra hjul monterat chassi 10, vilket bär själva kärlet 11. Detta kärl är avsett för användning i en stor processanlâggning, t.ex. för framställning av läkemedel, och är försett med ett antal inlopp och utlopp 12 och reglerventiler 13. Olika sterila vätskor matas till kärlet, där de blandas samman medelst en drivanordning 14, varefter den resulterande blandningen tappas av från kärlet.The mixing vessel shown in Fig. 1 comprises a chassis 10 mounted on four wheels, which carries the vessel itself 11. 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 and outlets 12 and control valves 13. Various sterile liquids are fed to the vessel, where they are mixed together by means of a drive device 14, after which the resulting mixture is drained from the vessel.

Drivanordningen 14 visas tydligare i Fig. 2 och omfattar en frán tankens botten inåt riktad, cylindrisk försänkning 15 i tankväggen 16, vilken försänkning är insvetsad pà så sätt att inga öppningar eller genomföringar förekommer i denna del av tankvâggen. En omrörare 17 är lagrad på en axeltapp 18 som är centralt placerad på en ândvägg 19, vilken avgränsar den cylindriska försänkningen 15.The drive device 14 is shown more clearly in Fig. 2 and comprises an inwardly directed cylindrical recess 15 from the bottom of the tank in the tank wall 16, which recess is welded in such a way that no openings or penetrations occur in this part of the tank wall. A stirrer 17 is mounted on a shaft pin 18 which is centrally located on an end wall 19, which delimits the cylindrical recess 15.

Omröraren 17 är liksom kärlet 11 huvudsakligen tillverkad av rostfritt syrafast stål, med ett antal svängda blad 20 och en central lyftring 22. Omröraren 17 uppvisar ett periferiellt parti 21 som omger den cylindriska försänkningen 15 och inrymmer ett genom induktion magnetiserbart plattpaket 23 till .way 462 834 en rotor som är avsedd för användning i en trefas växelströms- 3 motor av ytterrotortyp.The agitator 17, like the vessel 11, is mainly made of stainless acid-resistant steel, with a number of curved blades 20 and a central lifting ring 22. The agitator 17 has a peripheral portion 21 which surrounds the cylindrical recess 15 and houses an induction magnetizable plate package 23 to .way 462 834 a rotor intended for use in a three-phase external rotor-type AC motor.

I försänkningen 15 är en stator 24 fast monterad och omfattar en magnetiserbar järnkärna 25 och till trefas växelströmkàlla anslutbara induktionsspolar. När dessa spolar magnetiseras av växelströmmen magnetiseras även plattpaketet 23 genom induktion och den genom växelströmmen varierande riktningen i magnetfältet ger upphov till krafter som strävar att vrida runt omröraren 17 i en förutbestämd riktning.In the recess 15, a stator 24 is fixedly mounted and comprises a magnetizable iron core 25 and induction coils connectable to three-phase AC power source. When these coils are magnetized by the alternating current, the plate package 23 is also magnetized by induction and the direction varying through the alternating current in the magnetic field gives rise to forces which tend to rotate around the stirrer 17 in a predetermined direction.

Fig. 3 visar en reglercentral 26 för styrning av omrörarens drivning, omfattande en strömbrytare 27, en varvtalsregulator 28 och en med statorn 24 i drivanordningen förbunden ström- kabel 29. Lämpligen medger varvtalsregulatorn 28 steglös variation av omrörarens 17 varvtal i omrâdet av cirka 0-500 v/min.Fig. 3 shows a control center 26 for controlling the agitator drive, comprising a switch 27, a speed regulator 28 and a power cable 29 connected to the stator 24 in the drive device. Preferably, the speed regulator 28 allows stepless variation of the agitator 17 speed in the range of approx. 500 rpm

Uppfinningen är ej begränsad till det ovan beskrivna ut- föringsexemplet, utan flera varianter är tänkbara inom ramen för efterföljande krav. Exempelvis kan drivanordningen vara försedd med någon form av kylning, t.ex. en fläkt.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 drive device may be provided with some form of cooling, e.g. a fan.
