Description

Anordning for innføring og forbrenning av støv i roterende ovner. Device for introducing and burning dust in rotary kilns.

Ved roterende ovner, f. eks. kalkbrenningsovner vil halvbrent støv felles ut i In rotary kilns, e.g. lime-burning kilns, half-burnt dust will fall out

støvkammeret mellom ovn og skorsten, og the dust chamber between the furnace and the chimney, and

det har vært et problem hva man skal gjøre it has been a problem what to do

med dette støv. Enkelte steder, hvor for-holdene gjør dette mulig, har støvet delvis with this dust. In some places, where the conditions make this possible, the dust has partially fallen

gått til landbruket og delvis blitt tippet på went to agriculture and was partly tipped over

sjøen. I forbindelse med disse typer av the sea. In connection with these types of

roterende ovner kjennes også forslag som rotary kilns are also known suggestions as

går ut på å føre støvet inn i ovnen pånytt. involves feeding the dust into the oven again.

Foreliggende oppfinnelse går ut på en The present invention is based on a

ny særlig ved kalkbrenningsovner anven-delig gunstig anordning for innføring påny new, especially with lime-burning kilns, useful device for re-introduction

i ovnen av det støv som oppstår under ovnens drift, og som felles ut i støvkammeret. in the oven from the dust that arises during the operation of the oven, and which is deposited in the dust chamber.

Således vedrører oppfinnelsen en anordning ved roterende ovner, f. eks. kalkbrenningsovner for forbrenning av det Thus, the invention relates to a device for rotary ovens, e.g. lime kilns for burning it

halvbrente støv som felles ut i et støvkam-mer mellom ovn og skorsten, hvor støvet half-burnt dust that falls out in a dust chamber between the oven and the chimney, where the dust

blåses inn i ovnens utløpsende på en sådan is blown into the outlet end of the furnace on such

måte at det får et kort opphold i ovnen og way that it has a short stay in the oven and

derved blir ferdigbrent, hvoretter det føres thereby being finished burning, after which it is carried

ut sammen med resten av godset, idet denne anordning i henhold til oppfinnelsen er out together with the rest of the goods, as this device according to the invention is

karakterisert ved at der i forbindelse med characterized in that there in connection with

støvkammeret er anordnet et annet kammer som er beregnet på å bli tilført støv the dust chamber is arranged in another chamber which is intended to be supplied with dust

fra støvkammeret, og som på den ene side from the dust chamber, and as on one side

står i forbindelse med en ledning og en is in connection with a wire and a

herfra avgrenet ledning for innblåsing av branched line from here for blowing in

pressluft i kammeret, og på den annen side compressed air in the chamber, and on the other hand

ved en ledning står i forbindelse med ovnens utløpsende, idet der mellom støvkam-meret og det nevnte annet kammer er anordnet en ventil som stenges ved innblåsing av luft i ventilhuset gjennom en gren by a line is in connection with the outlet end of the oven, since there is a valve arranged between the dust chamber and the aforementioned second chamber which is closed when air is blown into the valve housing through a branch

av ledningen, slik at støv som befinner seg of the cord, so that dust that is located

i kammeret ved hjelp av pressluft fra led- in the chamber using compressed air from the

ningen blåses ut, og inn i ovnens utløps-ende. Det har vist seg at behandlingen av støvet på den ovenfor angitte måte virker meget tilfredsstillende. ning is blown out and into the outlet end of the oven. It has been shown that the treatment of the dust in the manner indicated above works very satisfactorily.

En anordning i henhold til oppfinnelsen er nærmere beskrevet i det følgende, under henvisning til tegningen, hvor: Fig. 1 skjematisk anskueliggjør anordningen og dennes virkemåte. Fig. 2 og 3 viser den ved anordningen i henhold til fig. 1 anvendte ventil i hen-holdsvis vertikalt lengdesnitt og horison-talt tverrsnitt. A device according to the invention is described in more detail below, with reference to the drawing, where: Fig. 1 schematically illustrates the device and its mode of operation. Fig. 2 and 3 show it in the device according to fig. 1 used valve in vertical longitudinal section and horizontal cross-section, respectively.

Under henvisning særlig til fig. 1, be-tegner 1 støvkammeret, under hvilket og i direkte tilknytning til samme der er anordnet et annet kammer 2. Mellom de to kammere er der festet en plate eller flens 3 med en sentral åpning 4, på en sådan With particular reference to fig. 1, 1 denotes the dust chamber, below which and in direct connection with it another chamber 2 is arranged. Between the two chambers there is fixed a plate or flange 3 with a central opening 4, on such

måte at kammeret 2 er festet til kammeret way that the chamber 2 is attached to the chamber

1 under formidling av denne plate 3. Til 1 during dissemination of this plate 3. To

platen 3 under åpningen 4 er der sveiset et av flattjern bestående bur 5 (se fig. 2). Til undersiden av buret 5 er der under formidling av en ring 6 festet en plate 7. Til denne plate 7 er sveiset et sylindrisk ventilhus 8, over hvilket et kjegleformig ventillegeme 9 er teleskopisk forskyvbart. plate 3 below the opening 4, a cage 5 consisting of flat iron is welded there (see fig. 2). A plate 7 is attached to the underside of the cage 5 by means of a ring 6. A cylindrical valve housing 8 is welded to this plate 7, above which a cone-shaped valve body 9 is telescopically displaceable.

Som vist i fig. 2 er der under åpningen 4 festet en sylindrisk ring 10, hvis under-kant danner sete for ventillegemet 9. En ledning 11 fører fra en kilde for blåseluft, fortrinnsvis en pneumatisk pumpe. En gren 11' av denne ledning fører inn i det indre av ventilhuset 8 gjennom en midt-åpning i platen 7. En annen gren 11" av ledningen 11 fører direkte inn i kammeret 2. Foran avgreningen er der i ledningen 11 innskutt en ventil 12. Fra bunnen av kammeret 2 fører en ledning 13 til ovnens ut-løpsende. As shown in fig. 2, a cylindrical ring 10 is attached under the opening 4, the lower edge of which forms a seat for the valve body 9. A line 11 leads from a source of blowing air, preferably a pneumatic pump. A branch 11' of this line leads into the interior of the valve housing 8 through a central opening in the plate 7. Another branch 11" of the line 11 leads directly into the chamber 2. In front of the branch, a valve 12 is inserted in the line 11 From the bottom of the chamber 2, a line 13 leads to the outlet end of the furnace.

Anordningen virker på følgende måte: Under ovnens omdreining vil en arm The device works in the following way: During the rotation of the oven, an arm will

på ovnen åpne ventilen 12, slik at trykk-luft føres inn i det indre av ventilhuset 8, on the stove, open the valve 12, so that compressed air is introduced into the interior of the valve housing 8,

og ventillegemet 4 vil bli løftet mot sitt sete. and the valve body 4 will be lifted towards its seat.

Derved stenges for støvtilførsel fra kammeret 1 til kammeret 2. Gjennom lednings-grenen 11" vil det støv som befinner seg i Thereby, the supply of dust from chamber 1 to chamber 2 is closed. Through the line branch 11", the dust that is in

kammeret 2 bli hvirvlet rundt og sammen the chamber 2 be swirled around and together

med luften blåses gjennom ledningen 13 til with the air blown through the line 13 to

den roterende ovns utløpsende, det vil si the outlet end of the rotary kiln, that is

den ende i hvilken det ferdigbrente mate-riale kommer ut. Derved blir støvet sammen med luften blåst et stykke inn i ovnen. the end at which the finished burnt material comes out. Thereby, the dust together with the air is blown some distance into the oven.

I neste omgang vil en annen arm på den In the next round, another arm will be on it

roterende ovn påvirke ventilen 12, slik at rotary oven affect the valve 12, so that

denne stenges. Ventillegemet 9 faller da this is closed. The valve body 9 then falls

ned, slik at støvet fra støvkammeret kan down, so that the dust from the dust chamber can

renne ned i kammeret 2. Virkemåten blir flow down into the chamber 2. The way it works is

således helt automatisk. thus completely automatically.
