Description
Uttakanordning for sj alctovner.Outlet device for self-heating stoves.
Foreliggende oppfinnelse gjelder en uttakanordning for sjaktovner, særlig ovner for direkte reduksjon. Ved sjaktovner for direkte reduksjon er det f.eks. kjent å anvende en skyvebjelke, som på et rektangulært bord utforer en bevegelse frem og tilbake og derved trykker den frembragteireduserte jernsvamp stdtvis over to innbyrdes motstående bordkanter. Denne skyvebjelke og de skyve-stenger som beveger bjelken, er innhule og av holdigasthetsgrunner vannkjolt. The present invention relates to an outlet device for shaft furnaces, in particular furnaces for direct reduction. In the case of shaft furnaces for direct reduction, there is e.g. known to use a push beam, which on a rectangular table carries out a movement back and forth and thereby presses the produced reduced iron sponge over two mutually opposite table edges. This sliding beam and the sliding rods that move the beam are hollow and, for durability reasons, water-jacketed.
Særlig skyvestengene trekker ut meget varme fra reduksjonsgassene, hvilket er en prosessteknisk ulempe. Den angitte tosidige The push rods in particular extract a lot of heat from the reducing gases, which is a process engineering disadvantage. The indicated two-sided
utskyvning av jernsvampen gjor det også nddvendig med et rektangel-formet sjakttverrsnitt, idet minste over sjaktens nederste del, for å oppnå en jevn synkehastlghet for fyllgodset. Dette er imidlertid fasthetsmessig og murteknisk ugunstig. En sådan konstruksjon pushing out the iron sponge also makes it necessary to have a rectangle-shaped shaft cross-section, the smallest over the bottom part of the shaft, in order to achieve a uniform sinking speed for the fill. However, this is disadvantageous in terms of strength and masonry technology. Such a construction
medforer nemlig sammenlignet med vanlige runde sjaktovner et hoyt materialforbruk. Det samme gjelder for de ovnsdeler som ligger nedenfor sjakten, som hittil har vært sammensatt av plane flater. in comparison with ordinary round shaft furnaces, entails a high material consumption. The same applies to the furnace parts below the shaft, which until now have been composed of flat surfaces.
På denne bakgrunn er det e&cforraål for oppfinnelsen å fremskaffe en uttakanordning for sjaktovner, særlig for ovner med direkte reduksjon, og hvorved de omtalte ulemper ikke forekommer, mengden av tilf 6rt reduksjonsgass ikke påvirkes og en jevn synkehastlghet for fyllgodset sikres. I Henhold til oppfinnelsen er det da funnet at en sådan særegen uttakanordning kan frembringes ved at det ved de&vjaisdre ende av en sirkelrund sjakt midt i sjaktens tverrsnitt og over et saralerom for opptagelse av redusert ovngods er anbragt et sirkulært bord som omgir et eventuelt akseforskyvbart opplagret fortrengningshjul med vertikal dreieakse og rotas^onsdrev samt utstyrt med gjennomgående kjolemiddal-kanaler og fortrengnings-skyffler som eventuelt er Icruramet mot hjulets dreieretning, såvel som eventuelt forskyvbart anordnede tilleggsskyffler, idet en sentralkjegle er anordnet midt på fortregningshjulet. On this background, it is necessary for the invention to provide an outlet device for shaft furnaces, in particular for furnaces with direct reduction, and whereby the mentioned disadvantages do not occur, the amount of supplied reduction gas is not affected and a uniform sinking rate for the filling material is ensured. In accordance with the invention, it has then been found that such a distinctive take-out device can be produced by placing a circular table at the opposite end of a circular shaft in the middle of the shaft's cross-section and above a storage space for receiving reduced kiln goods, which surrounds a possibly axially displaceable displacement wheel with a vertical axis of rotation and rotas^on drive as well as equipped with continuous dress media channels and displacement paddles which are optionally Icruramed against the direction of rotation of the wheel, as well as possibly displaceably arranged additional paddles, a central cone being arranged in the middle of the displacement wheel.
Oppfinnelsen vil n^. bli nærmere forklart ved hjelp av ikke begrensende utfSreisesekserapler og under henvisning til de vedfdyde tegninger, hvorpåi The invention will n^. be explained in more detail with the help of non-limiting export sex appeals and with reference to the attached drawings, whereupon

Tilfdrsel av fyllgods, slik som f .eks. jernmalm 1, til en sirkelrund sjalet 2 oppnås gjennom en vanlig innlopslås 3. Reduksjonsgassene tilfares ved 4 og tas ut ved 5 (bare et r6r antydet på hvert sted). Fyllgodset hviler på et sirkelrundt bord 6, et fortrengningshjul 7 og en sentralkjegle 8. Ved en dreining som angitt i fig. 2, trykkes fyllgodset 1, f.eks. jernsvamp, ut over kanten av bordet 6 for å falle ned i de to samlerom 9 1 den nedre del av ovnen, hvor godset tas ut på kjent måte gjennom sluser 10. Fortrengningsh julet er opplagret på undersiden av sjakten og drives også fra dette sted, samt er evnetuelt avtetfcet mot ovnsrommet. Supply of fillers, such as e.g. iron ore 1, to a circle round the shawl 2 is obtained through an ordinary inlet lock 3. The reducing gases are admitted at 4 and taken out at 5 (only a r6r indicated at each place). The filling material rests on a circular table 6, a displacement wheel 7 and a central cone 8. By turning as indicated in fig. 2, the filler 1 is pressed, e.g. iron sponge, out over the edge of the table 6 to fall into the two collecting rooms 9 1 the lower part of the furnace, where the goods are taken out in a known manner through sluices 10. The displacement h Christmas is stored on the underside of the shaft and is also operated from this place, as well as being sealed against the oven room.
Fortrengningshjulet kan, som angitt i fig. 3, fortrinnsvis være avkjolt ved hjelp ar kjolemiddelkanaler 20. Sentralkjeglen kan også vare dreibart påsatt hjulet. The displacement wheel can, as indicated in fig. 3, preferably be cooled using cooling medium channels 20. The central cone can also be rotatably attached to the wheel.
Utakkshastigheten kan varieres ved forandring av fortrengnings-hjulets omdreiningstall. En ytterligere forhdyet uttakshastighet og en fullstendig tomning av oMnsbordet 6 kan oppnås ved at det, som vist i fig. 4, innenfor fortrmgningsskyfflene 14 anbringes forskyvbare tillegsskyf f ler 15, som f .eks. kan forskyves ved hjelp av leddstenger 18 ved vinkelforskyvning av en veivring 16 mot fortrgngningshjulets aksel 17. Ytterligere variasjonsmuligheter foreligger hvis fortrengningshjulet 7 er akseforskyvbart opplagret, f «eies. over to eksenterringer eller eksenterskiver 19, således at en stdrre bordflate enn det som tilsvarer fortre^gningshjulets diameter, kan overstrykes (fig.5). The extraction speed can be varied by changing the speed of the displacement wheel. A further increased extraction speed and a complete emptying of the rotary table 6 can be achieved by, as shown in fig. 4, displaceable additional paddles 15 are placed within the displacement paddles 14, which e.g. can be displaced by means of connecting rods 18 by angular displacement of a crank ring 16 towards the displacement wheel's shaft 17. Further variation possibilities exist if the displacement wheel 7 is axially displaceable stored, f «eies. over two eccentric rings or eccentric discs 19, so that a larger table surface than that which corresponds to the diameter of the deceleration wheel can be crossed over (fig.5).
