Description
Foreliggende oppfinnelse angår en anordning av den i inn-ledningen til krav 1 angitte art for fremstilling av fibermatte av mineralullfibre. The present invention relates to a device of the type specified in the introduction to claim 1 for the production of fiber mats from mineral wool fibres.
Ved vanlig fremstilling av mineralull smeltes en blan-ding av koks, diabas og flussmiddel, såsom kalksten, i en ovn og en strøm av den oppnådde smelte spinnes ved hjelp av et fibreringsaggregat til fibre. Fibreringsaggegatet utgjøres av et flertall, innved hverandre beliggende, hurtig roterende valser med horisontale aksler og fibrene dannes ved at smeltestrømmen, når den treffer valsene, slites i stykker i dråper som av sen-trifugalkraften slynges ut og samtidig strekkes til fibre. Fibrene føres fra spinneaggregatet ut i et spinnekammer, hvori de samles opp på et oppsamlingsbånd. For å styre transporten av fibrene fra fibreringsaggregatet ut i spinnekammeret er spinneaggregatet forsynt med munnstykker, fortrinnsvis i form av spal-ter som retter en kraftig gasstrøm mot de nydannede fibre og tvinger dem mot spinnekammerets andre ende. Samtidig påføres fibrene også en bindemiddeloppløsning samt et smøremiddel for å minske støvdannelsen. Til denne påføring finnes det munnstykker ved fibreringsaggregatet. Bak oppsamlingsbåndet finnes det videre et vifteaggregat, som skaper et undertrykk i spinnekammeret og derved medvirker til at fibrene føres fra spinneaggregatet til oppsamlingsbåndet. Ved at smeiten ved spinningen ikke trek-kes helt ut til fibre, dannes også endel partikulært materiale, såkalte perler, som ikke er ønskelige i det ferdige produkt og som man derfor forsøker å skille fra fibrene. Denne fraskilling tilveiebringes f.eks. ved å anordne en terskel i fiberstrømmens vei, hvorigjennom fiberstrømmen avledes og endel av perlene skilles ut og faller ned i en avfallssjakt. På grunn av den kraf-tige gasstrøm som råder, ikke minst gjennom de ringformede på-blåsningsmunnstykker, rives imidlertid endel perler med uten å skilles ut og kommer til å inngå i det ferdige produkt. Ved at videre gasstrømmens hastighet i spinnekammeret minsker suksessivt fra spinneaggregatet ved kammerets inngangsende og mot oppsamlingsbåndet ved kammerets utgangsende, kommer senere dannede fibre under sin transport gjennom spinnekammeret å nå de tidligere dannede fibre, hvorved det dannes floker. Gasstrømmens hastighetsminskning skaper dessuten kraftig turbulens i spinnekammeret, hvilket er en ytterligere årsak til sammenklumping og flokedannelse. De således dannede fiberfloker medfører en ujevn fiberavsetning på oppsamlingsbåndet, hvilket igjen inne-bærer at det endelige produkt har en ikke ønskelig, ujevn fiberfordeling. Flokedannelsen i spinnekammeret har ytterligere en ulempe ved at den medfører at påføringen av bindemiddel blir ujevn, ettersom bindemiddeloppløsningen ikke formår å trenge inn i flokene. In the usual production of mineral wool, a mixture of coke, diabase and flux, such as limestone, is melted in a furnace and a stream of the obtained melt is spun using a fiberizing unit into fibers. The fiberizing aggage consists of a plurality of closely spaced, rapidly rotating rollers with horizontal axes and the fibers are formed by the melt flow, when it hits the rollers, being torn into pieces which are thrown out by the centrifugal force and simultaneously stretched into fibers. The fibers are fed from the spinning unit into a spinning chamber, where they are collected on a collection belt. In order to control the transport of the fibers from the fiberization unit out into the spinning chamber, the spinning unit is provided with nozzles, preferably in the form of slits which direct a strong gas flow towards the newly formed fibers and force them towards the other end of the spinning chamber. At the same time, a binder solution and a lubricant are also applied to the fibers to reduce dust formation. For this application, there are nozzles at the fibering unit. Behind the collection belt there is also a fan assembly, which creates a negative pressure in the spinning chamber and thereby contributes to the fibers being carried from the spinning assembly to the collection belt. As the melt is not completely drawn out into fibers during spinning, some particulate material is also formed, so-called pearls, which are not desirable in the finished product and which one therefore tries to separate from the fibers. This separation is provided e.g. by arranging a threshold in the path of the fiber flow, through which the fiber flow is diverted and part of the beads are separated and fall into a waste chute. However, due to the strong gas flow that prevails, not least through the ring-shaped blow-on nozzles, some beads are carried along without being separated and become part of the finished product. As the speed of the gas flow in the spinning chamber decreases successively from the spinning unit at the entrance end of the chamber and towards the collection belt at the exit end of the chamber, later formed fibers come during their transport through the spinning chamber to reach the previously formed fibers, whereby tangles are formed. The reduction in speed of the gas stream also creates strong turbulence in the spinning chamber, which is a further cause of clumping and tangle formation. The thus formed fiber tangles result in an uneven fiber deposition on the collection belt, which in turn means that the final product has an undesirable, uneven fiber distribution. The tangle formation in the spinning chamber has a further disadvantage in that it causes the application of binding agent to be uneven, as the binding agent solution does not manage to penetrate the tangles.
Fra svensk utlegningsskrift 386 887 er det tidligere kjent ved fremstilling av fibermatter å regulere den avtagende strømningshastighet mellom fiberdannelsesorganer og det transportbånd hvorpå fibrene avsettes. Strømningskammeret har suksessivt økende tverrsnittsareal som ved utløpet er 1-2 ganger større enn ved innløpet. Virkningen av denne økning av tverr-snittsarealet motvirkes gjennom tilførsel av tilskuddsluft, slik at mengden av strømmende fluidum og dermed gasshastigheten forblir i hovedsaken konstant langs hele strømningsbanen. From Swedish specification 386 887 it is previously known in the production of fiber mats to regulate the decreasing flow rate between fiber forming means and the conveyor belt on which the fibers are deposited. The flow chamber has a successively increasing cross-sectional area which at the outlet is 1-2 times larger than at the inlet. The effect of this increase in the cross-sectional area is counteracted through the supply of supplementary air, so that the amount of flowing fluid and thus the gas velocity remains essentially constant along the entire flow path.
I US patent 2 172 153 er en fremgangsmåte for fremstilling av en fibermatte ved hjelp av et gassformig medium beskre-vet, hvor fibrene som er dannet i et fibreringsaggregat, ledes gjennom et langstrakt kammer med tildels konstant og tildels varierende tverrsnittsform og tverrsnittsareal for oppnåelse av en viss turbulens og dermed sammenfilting av fibrene mens de fremdeles transporteres av den gassformige bærer. In US patent 2 172 153, a method for producing a fiber mat using a gaseous medium is described, where the fibers formed in a fibering unit are led through an elongated chamber with partly constant and partly varying cross-sectional shape and cross-sectional area to obtain a certain turbulence and thus entanglement of the fibers while they are still transported by the gaseous carrier.
Hensikten med denne oppfinnelse er å tilveiebringe en anordning av den innledningsvis nevnte art som forsinker dannel-sen av fiberdotter, -fnokker eller -buster o.l. så lenge som mulig, slik at den egentlige sammenfiltingsprosess i størst mulig grad skjer på selve oppsamlingsbåndet eller enden av spinnekammeret. Dette er oppnådd ved hjelp av de i hovedkravets karakteristikk angitte trekk. The purpose of this invention is to provide a device of the type mentioned at the outset which delays the formation of fiber lint, fuzz or bristles etc. as long as possible, so that the actual felting process takes place to the greatest extent possible on the collection belt itself or the end of the spinning chamber. This has been achieved with the help of the features specified in the characteristics of the main requirement.
Følgen er at man ved hjelp av anordningen ifølge oppfinnelsen oppnår en meget jevnere fiberavsetning på oppsamlingsbåndet og dermed et endelig produkt med jevnere fiberfordeling. The consequence is that, with the aid of the device according to the invention, a much more even fiber deposition is achieved on the collection belt and thus a final product with a more even fiber distribution.
Oppfinnelsen skal forklares nærmere nedenfor ved hjelp av et eksempel og under henvisning til tegningen, hvor: Fig. 1 viser et sterkt skjematisert sideriss av en fore-trukket anordning ifølge oppfinnelsen, og fig. 2 viser et hori-sontalriss av anordningen ifølge fig. 1 tatt langs linjen II-II på fig. 1. The invention will be explained in more detail below by means of an example and with reference to the drawing, where: Fig. 1 shows a highly schematic side view of a preferred device according to the invention, and fig. 2 shows a horizontal view of the device according to fig. 1 taken along the line II-II in fig. 1.
Som antydet på fig. 1 dannes mineralullen ved spinnekammerets 1 ene ende, inngangsenden 2, ved at smeltet mineral 3 mates ut fra et eller flere munnstykker 4 mot et fibreringsaggregat 5 som består av minst en og fortrinnsvis to eller flere, raskt roterende sylindre 6 med stort sett horisontale akser. As indicated in fig. 1, the mineral wool is formed at one end of the spinning chamber 1, the entrance end 2, by molten mineral 3 being fed from one or more nozzles 4 towards a fibering unit 5 which consists of at least one and preferably two or more, rapidly rotating cylinders 6 with largely horizontal axes.
Fra sylindrene 6 slynges mineralsmelten ut på grunn av sentri-fugalkraften i form av tynne fibre 7 samt perler, som ikke har gjennomgått fiberdannelse. Det dannede mineralullmaterialet rives med av en gasstrøm inn i spinnekammeret 1 og videre mot spinnekammerets andre ende, utgangsenden 8. Gasstrømmen gjennom spinnekammeret 1 skapes av et vifteorgan 9, som er beliggende bortenfor spinnekammerets utgangsende og som suger luft gjennom spinnekammeret 1. Det vesentlige er at det skapes en trykk-forskjell mellom inngangsenden 2 og utgangsenden 8, slik at det fåes en gasstrøm fra inngangsenden 2 og mot utgangsenden 8. Det skal påpekes at ved den viste, foretrukne utførelse av anordningen ifølge oppfinnelsen benyttes ikke blåsemunnstykker i fibreringsaggregatet, da slike munnstykker har lett for å øke med-rivningen av perler i fiberstrømmen. For å skape forutsetnin-ger for en turbulensfri gasstrømning gjennom spinnekammeret er som tidligere nevnt inngangsenden 2 blitt gjort så åpen som mulig for i minst mulig utstrekning å hindre gasstrømmens inntre-delse i spinnekammeret 1. Det er også fordelaktig å avrunde hjørner og kanter i gasstrømmens vei. Inngangsendens 2 åpne form tillater også enkel anordning av ytterligere fibreringsaggregater hvorved produksjonskapasiteten økes. For å utskille perler og annet avfallsmateriale finnes det en sjakt 10 ved inngangsenden 2, i hvilken sjakt avfallsmaterialet faller ned og transporteres bort. Det avfallsmateriale som faller ned i sjakten 10 stammer dels fra partikkelformet materiale, som faller direkte ned i sjakten i forbindelse med fiberdannelsen i fibreringsaggregater, dels fra partikkelformet materiale som rives med av gasstrømmen inn i spinnekammeret 1, men der sepa-reres fra fibrene 7 og faller ned på kammerets bunn. Sistnevn-te bunn utgjøres av et transportbånd 11 som mater det oppfange-de, partikkelformede materiale til sjakten 10. Transportbåndet 11 bør være anordnet hovedsakelig horisontalt for å unngå at også fibre oppsamles på båndet. From the cylinders 6, the mineral melt is ejected due to the centrifugal force in the form of thin fibers 7 and beads, which have not undergone fiber formation. The formed mineral wool material is pulled along by a gas flow into the spinning chamber 1 and further towards the spinning chamber's other end, the exit end 8. The gas flow through the spinning chamber 1 is created by a fan member 9, which is located beyond the exit end of the spinning chamber and which sucks air through the spinning chamber 1. The essential thing is that a pressure difference is created between the input end 2 and the output end 8, so that a gas flow is obtained from the input end 2 and towards the output end 8. It should be pointed out that in the shown, preferred embodiment of the device according to the invention, blowing nozzles are not used in the fiberization unit, as such nozzles has a tendency to increase the entrainment of beads in the fiber flow. In order to create the conditions for a turbulence-free gas flow through the spinning chamber, as previously mentioned, the inlet end 2 has been made as open as possible to prevent the gas flow from entering the spinning chamber 1 to the smallest extent possible. It is also advantageous to round corners and edges in the gas flow road. The open shape of the input end 2 also allows easy arrangement of additional fibering aggregates, whereby the production capacity is increased. In order to separate beads and other waste material, there is a chute 10 at the entrance end 2, in which chute the waste material falls down and is transported away. The waste material that falls into the shaft 10 originates partly from particulate material, which falls directly into the shaft in connection with the fiber formation in fibering aggregates, and partly from particulate material that is carried along by the gas flow into the spinning chamber 1, but is separated from the fibers 7 and falls to the bottom of the chamber. The latter bottom is made up of a conveyor belt 11 which feeds the collected, particulate material to the shaft 10. The conveyor belt 11 should be arranged mainly horizontally to avoid fibers also being collected on the belt.
For å unngå turbulens skal gasstrømmen og fnokkdannelsen akselereres langs sin vei gjennom spinnekammeret 1, hvorved gasstrømmens hastighet øker suksessivt. Denne akselerasjon og hastighetsøkning hos gasstrømmen tilveiebringes ved at spinnekammerets 1 tverrsnittsareal minsker i retning mot dets utgangsende 8. Denne arealminskning kan oppnås ved at en eller flere av spinnekammerets vegger konvergerer i retning mot utgangsenden 8, og det foretrekkes å la de to loddrette vegger 17,18 konver-gere, såsom vist på fig. 2. In order to avoid turbulence, the gas flow and the formation of fluff must be accelerated along its path through the spinning chamber 1, whereby the speed of the gas flow increases successively. This acceleration and speed increase in the gas flow is provided by the cross-sectional area of the spinning chamber 1 decreasing in the direction towards its exit end 8. This reduction in area can be achieved by one or more of the walls of the spinning chamber converging in the direction towards the exit end 8, and it is preferred to let the two vertical walls 17, 18 converge, as shown in fig. 2.
Den for partikkelformet avfallsmateriale hovedsakelig befridde, akselererte, fiberholdige gasstrøm treffer til slutt The particulate waste material mainly freed, accelerated, fibrous gas stream finally hits
det gassgjennomslippelige oppsamlingsbånd 12 ved spinnekammerets utgangsende 8, hvorved gasstrømmen passerer gjennom oppsamlingsbåndet, mens fibrene 7 avsettes på båndet og danner en matte 13. Ved at oppsamlingsbåndet 12 er anordnet omkring to roterende valser 14,15, som på fig. 2 vises drevne i urviserens retning, mates-den dannede fibermatte 13 suksessivt oppover og ut av spinnekammeret 1 for deretter å overføres til et annet transportbånd 16 for viderebehandling. the gas-permeable collection belt 12 at the exit end 8 of the spinning chamber, whereby the gas flow passes through the collection belt, while the fibers 7 are deposited on the belt and form a mat 13. As the collection belt 12 is arranged around two rotating rollers 14,15, as in fig. 2 are shown driven in a clockwise direction, the formed fiber mat 13 is successively fed upwards and out of the spinning chamber 1 to then be transferred to another conveyor belt 16 for further processing.
For at man skal oppnå den tilsiktede virkning skal gass-strømmens hastighet økes med i alt 5-65%, fortrinnsvis ca. 25%, under akselerasjonen gjennom spinnekammeret 1. Akselerasjonen bør være størst nærmest fibreringsaggregatet 5, dvs. ved inngangsenden 2. Videre skal gasstrømmen akselereres langs en så stor del av strekningen mellom fibreringsaggregatet 5 og oppsamlingsbåndet 12 som mulig. Akselerasjon langs hele strekningen er vanskelig å oppnå i praksis, ettersom spinnekammeret må utvi-de seg ved utgangsenden 8 umiddelbart før oppsamlingsbåndet 12 for bl.a. å gi plass for utmatningen av den dannede fibermatte 13. In order to achieve the intended effect, the speed of the gas flow must be increased by a total of 5-65%, preferably approx. 25%, during the acceleration through the spinning chamber 1. The acceleration should be greatest closest to the fibering unit 5, i.e. at the input end 2. Furthermore, the gas flow must be accelerated along as large a part of the stretch between the fibering unit 5 and the collection belt 12 as possible. Acceleration along the entire stretch is difficult to achieve in practice, as the spinning chamber must expand at the exit end 8 immediately before the collection belt 12 for, among other things, to make room for the output of the formed fiber mat 13.
