Cp i form af smeltefibre, der afkøles og videretransporteres ved hjælp af en langs omkredsen af hver rotor fremført luftstrøm. y> Ved fremstilling af mineraluld ledes en strøm af flyden- Ω de smelte med en temperatur, der i almindelighed ligger 2 146297 inden for området 1000 - 1400°, tilvejebragt ved smeltning af bjergarter, slagger, glasdannende råmaterialer, såvel som andre uorganiske materialer i en smelteovn, i almindelighed en kupolovn, ned på et flertal - i reglen 4 - hurtigt omløbende rotorers omkredsflader. Rotorerne roterer parvis modsat, hvorved hovedstrømmen af smelte slynges fra den øverste rotor til den næste og så videre indtil al smelten er slynget bort fra rotorerne i form af smeltefibre. Denne proces betegnes normalt som en kaskadespindeproces.Cp in the form of melt fibers, which are cooled and re-transported by means of an air stream conveyed along the circumference of each rotor. y> In the production of mineral wool, a flow of the flowing melt is conducted at a temperature which is generally within the range of 1000 - 1400 °, provided by the melting of rocks, slag, glass-forming raw materials, as well as other inorganic materials. a melting furnace, generally a dome furnace, down on a plurality - usually 4 - of the orbiting surfaces of rapidly rotating rotors. The rotors rotate in pairs opposite, whereby the main flow of melt is flung from the top rotor to the next and so on until all the melt is thrown away from the rotors in the form of melt fibers. This process is usually referred to as a cascade spinning process.
Por dels at afkøle fibrene, dels at transportere dem til et transportbånd, hvorpå de opsamles og oparbejdes til måtter, plader osv, til termisk og akustisk isolering, fremføres der omkring rotorerne en luftstrøm fra en luftfordelingsindretning, der er placeret langs den udvendige kontur af rotorgruppen. For at undgå en afkøling af smeltestrømmen mellem rotorerne fremføres der ikke luft i mellemrummene mellem rotorerne, idet luften indblæses tilnærmelsesvis parallelt med rotorernes akser.To cool the fibers partly and to transport them to a conveyor belt, where they are collected and processed into mats, sheets, etc., for thermal and acoustic insulation, an air flow is fed around the rotors from an air distribution device located along the outer contour of the rotor group. . In order to avoid cooling of the melt flow between the rotors, no air is introduced into the spaces between the rotors, since the air is injected approximately parallel to the axes of the rotors.
Mineraluldsprodukter fremstillet ved den ovenfor beskrevne proces frembyder ofte en ikke tilfredsstillende traskstyrke, hvilket er en ulempe ved de færdige produkter, der let rives itu under transport og opsætning, men også' kan være til gene ved visse oparbejdningsprocesser, hvor mineralulden opsamles i et forholdsvis tyndt lag på et transportbånd og senere afgives i en sammenhængende bane, der doubleres til en større tykkelse. Den ringe trækstyrke viser sig navnlig ved mineraluldsprodukter med lav rumvægt og bevirker, at et produkt med en rumvægt på 2o kg/m , der iøvrigt er økonomisk fordelagtigt, ikke opnår tilstrækkelig styrke til at kunne håndteres under transport og opsætning.Mineral wool products produced by the process described above often present an unsatisfactory traction strength, which is a disadvantage of the finished products that are easily torn during transport and set-up, but may also be detrimental to certain work-up processes where the mineral wool is collected in a relatively thin layers on a conveyor belt and later released in a continuous web which is doubled to a greater thickness. The low tensile strength is particularly evident in low-weight mineral wool products and means that a product with a weight of 2o kg / m, which is otherwise economically advantageous, does not achieve sufficient strength to be handled during transport and set-up.
Formålet med den foreliggende opfindelse er at tilvejebringe en fremgangsmåde til fremstilling af mineraluld, ved hvilken der kan fremstilles produkter med højere trækstyrke end ved den ovenfor beskrevne kendte fremgangsmåde.The object of the present invention is to provide a process for producing mineral wool in which products with higher tensile strength than the above-described known process can be produced.
Det antages, at den forholdsvis lave trækstyrke, som mineraluld fremstillet ved en kaskadespindeproces opviser, 3 146297 skyldes, at mineralulden i væsentlig grad er opbygget af mineraluldstotter og ikke af overvejende jævnt fordelte mineraluldsfibre. Totterne kan have en størrelse på op til nogle få centimeter, og totterne kan i mange tilfælde have en rumvægt der er større end den tilsigtede gennemsnitsrumvægt for det produkt, hvori de indgår. Fiberindholdet i partierne mellem totterne kan da blive for ringe til at etablere en tilstrækkelig og tilfredsstillende forbindelse i disse partier, således at forbindelsen brydes, når mineralulden udsættes for trækkræfter under den almindelige håndtering .It is believed that the relatively low tensile strength exhibited by mineral wool produced by a cascading spinning process is due to the fact that the mineral wool is made up substantially of mineral wool stains and not of predominantly evenly distributed mineral wool fibers. The tots can be up to a few centimeters in size, and the tots can in many cases have a space weight greater than the intended average room weight for the product in which they are contained. The fiber content of the portions between the tufts may then become too low to establish a sufficient and satisfactory connection in these portions, so that the compound is broken when the mineral wool is subjected to traction during ordinary handling.
Dannelsen af totter skyldes efter hvad studier af det, der sker i områderne omkring en rotor ved kaskadespinderprocessen, viser, at fibre under afslyngning i det område, der ligger nærmest rotorens omkredsflade, danner et sammenhængende slør, der i nogen grad trækkes med i rotorens omløb, fordi det har mekanisk forbindelse med den ved rotoren hæftende smelte, og som samtidig i nogen grad trækkes ud i rotorens akseretning af den omgivende luftstrøm, indtil sløret rives op af luftstrømmen til totter bestående af sammenfiltrede, størknede fibre.The formation of tufts is due to what studies of what happens in the areas around a rotor during the cascade spinning process show that fibers during erosion in the area closest to the circumferential surface of the rotor form a coherent veil that is to some extent drawn into the rotor's orbit. because it has a mechanical connection with the melt adhering to the rotor, and which at the same time is withdrawn to some extent in the rotor's axis direction of the surrounding air flow until the veil is torn off by the air flow to tufts consisting of tangled, solidified fibers.
Ved fremgangsmåden ifølge opfindelsen, der er ejendommelig ved, at luftstrømmen dannes ud fra delluftstrømme, der frembringes ved siden af hinanden ved den ene roterende og langs hele rotorens periferi eller en del af denne, idet hver delluftstrøm meddeles en sådan retning, at den ud over en aksial hastighedskomponent tillige får en hastighedskomponent, der falder sammen med bevægelsesretningen af rotorens omkreds ud for frembringelsesstedet for den pågældende delluftstrøm.In the method according to the invention, characterized in that the air stream is formed from sub-air streams which are produced side by side at one or more of the rotor periphery or part thereof, each sub-air stream being communicated in such a way that it an axial velocity component also receives a velocity component which coincides with the direction of movement of the rotor circumference outside the generating point of the particular partial air flow.
Det har vist sig, at man i mineraluldprodukter fremstillet ved fremgangsmåden ifølge opfindelsen opnår tilnærmelsesvis en fordobling af trækstyrken i forhold til mineraluldprodukter af samme densitet fremstillet ved den kendte proces.It has been found that in mineral wool products made by the process according to the invention, approximately double the tensile strength relative to mineral wool products of the same density produced by the known process is obtained.
Den højere trækstyrke antages at hidrøre fra en mere ensartet fiberfordeling i mineraluldproduktet forårsaget af den mindre tæthed i de enkelte mineralfibertotter.The higher tensile strength is assumed to result from a more uniform fiber distribution in the mineral wool product caused by the lower density in the individual mineral fiber tufts.
Opfindelsen angår desuden et apparat til udøvelse af fremgangsmåden, hvilket apparat omfatter i det mindste en 4 146297 hurtigt omløbende rotor, der på et område af sin omkredsflade får tilført flydende smelte på en sådan måde, at smelten hæfter til omkredsfladen og afslynges derfra i form af smeltefibre, der afkøles og videretransporteres af en omkring rotoren fremført luftstrøm.The invention further relates to an apparatus for carrying out the method, which apparatus comprises at least one rotating rotor which at a region of its circumferential surface is supplied with a liquid melt in such a way that the melt is adhered to the circumferential surface and thrown therefrom in the form of melt fibers that are cooled and re-transported by an air stream conveyed around the rotor.
Ifølge opfindelsen er apparatet ejendommeligt ved, at der ved den ene ende af hver rotor langs omkredsfladens periferi eller langs en del af denne findes en med rotoren koncentrisk spalte, i hvilken der er placeret skovle, der er indrettet til at danne delluftstrømme af en mod spalten i retning af rotoren aksialt rettet luftstrøm og at meddele hver delluftstrøm en sådan retning at den ud over en aksial hastighedskomponent tillige får en hastighedskomponent, der falder sammen med bevægelsesretningen af rotorens omkreds, hvorhos skovlene er anbragt med en sådan tæthed, at delluftstrømmene umiddelbart efter skovlene danner en samlet luftstrøm.According to the invention, the apparatus is characterized in that at one end of each rotor along the periphery of the circumferential surface or along a part thereof there is provided a concentric gap with the rotor, in which there are vanes arranged to form partial air flows of a counter-gap. in the direction of the rotor axially directed air flow, and to communicate each partial air flow such a direction that, in addition to an axial velocity component, it also receives a velocity component coinciding with the direction of movement of the rotor circumference, the vanes being arranged with such density that the partial air currents immediately forming a total flow of air.
Skovlene kan ifølge en udførelsesform være placeret på en flange langs omkredsen af hver rotor, idet flangen udgør den ene begrænsning af spalten, medens den anden begrænsning dannes af et omkring rotoren placeret luftfordelingskammer.According to one embodiment, the vanes may be located on a flange along the circumference of each rotor, the flange constituting one restriction of the slot, while the other restriction being formed by an air distribution chamber located around the rotor.
Herved opnås der en god overensstemmelse mellem den tangenti-ale hastighedskomponent og rotorens omkredshastighed.Hereby a good agreement is obtained between the tangential velocity component and the rotor circumferential velocity.
Apparatet kan imidlertid ifølge opfindelsen også være udformet som angivet i krav 3. Det bliver herved muligt at variere den indblæste luftmængde og dens retning langs rotorernes omkreds, hvorved den indblæste luftmængde i områderne, hvor rotorerne støder op til hinanden, kan begrænses forikke at få en for kraftig afkøling af smelten.However, the apparatus according to the invention may also be configured as claimed in claim 3. Hereby it becomes possible to vary the air flow and its direction along the circumference of the rotors, whereby the air flow in the areas where the rotors abut each other can be limited to obtain a for excessive cooling of the melt.
Det kan herunder være hensigtsmæssigt at placere en afblændingsmaske ud for det område, hvor smelten tilføres på rotoren.Below, it may be convenient to place a glare mask off the area where the melt is applied to the rotor.
Opfindelsen skal i det følgende beskrives nærmere under henvisning til på tegningen viste udførelseseksempler. På tegningen viser fig. 1 en skitse til forklaring af fremgangsmåden ifølge opfindelsen, fig. 2 i udsnit et snit gennem en rotor og et luftfordelingskammer i en udførelsesform, hvor skovlene er placeret på rotoren, 146297 5 fig. 3 et udsnit af en rotor og et luftfordelingskammer med faste skovle i spalten, ligeledes i aksialsnit, og fig. 4 og 5 viser et snit langs henholdsvis AA og BB i fig. 2 og 3.The invention will now be described in more detail with reference to the exemplary embodiments shown in the drawing. In the drawing, FIG. 1 shows a sketch for explaining the method according to the invention; FIG. 2 is a sectional view of a rotor and an air distribution chamber in an embodiment where the vanes are located on the rotor; FIG. 3 is a sectional view of a rotor and an air distribution chamber with fixed blades in the slot, also in axial section; and FIG. 4 and 5 show a section along AA and BB respectively in FIG. 2 and 3.
Fig. 1 viser en rotor 1, hvis omdrejningsretning er angivet ved pilen O. En strøm af flydende smelte løber ned mod rotorens omkredsflade lo, hvorved smelten klæber fast til fladen og derved føres et stykke med rundt inden smelten slynges bort fra fladen i form af smeltefibre. Langs omkredsfladen lo forløber der en med rotoren 1 koncentrisk spalte 11 til indblæsning af en luftstrøm, der tjener til borttransport og afkøling af fibrene. I spalten 11 er der anordnet skovle, der sørger for at luftstrømmen, der indblæses aksi-alt med hastigheden Va vist ved en Vektor Vfl tillige modtager en tangential hastighedskomponent V i rotorens omløbsretning .FIG. 1 shows a rotor 1 whose direction of rotation is indicated by the arrow O. A flow of liquid melt runs down towards the circumferential surface of the rotor, whereby the melt adheres to the surface and is then passed a bit around before the melt is thrown away from the surface in the form of melt fibers. Along the circumferential surface 1o there is a gap 11 concentric with the rotor 1 for blowing in an air stream which serves to transport and cool the fibers. In the slot 11 there are provided vanes which ensure that the air flow which is blown in axially at the speed Va shown by a Vector Vf1 also receives a tangential velocity component V in the direction of rotation of the rotor.
Ved indblæsning af køleluften på denne måde opnås der en større åbning i det slør af smeltefibre, som omgiver rotoren inden fibrene i form af større eller mindre totter føres til et luftgennemtrængeligt bånd fra hvis underside luften bortsuges, hvorved smeltefibrene aflejres som en mineraluldsmåtte.By blowing the cooling air in this way, a larger opening is obtained in the veil of melt fibers surrounding the rotor before the fibers in the form of larger or smaller tacks are fed to an air permeable band from whose underside the air is sucked off, whereby the melt fibers are deposited as a mineral wool mat.
Fig. 2 viser et udsnit af et aksialsnit gennem en rotor 1, der er monteret på en aksel 5, der løber i et akselleje 6. Rotoren 1 består af en fælg med omkredsfladen lo og rotorflanger 2 og 3. Flanger og fælg er sammenholdt mod et bryst 5a på akslen ved hjælp af en møtrik 4. Langs omkredsen lo er der udformet en luftspalte 11 mellem en krave på den inderste flange 3 og en væg 7 på et aksellejet omgivende luftkammer. I spalten er der anordnet skovle 8, som sidder fast på kraven på rotorflangen 3. Skovlene 8 forløber i hovedsagen aksialt og meddeler den gennnem spalten 11 udtrædende luftstrøm en tangential hastighedskomponent V^ på grund af skovlenes rotation.FIG. 2 shows a section of an axial section through a rotor 1 mounted on a shaft 5 running in a shaft bearing 6. The rotor 1 consists of a rim with circumferential surface 1o and rotor flanges 2 and 3. Flanges and rim are joined together against a chest. 5a on the shaft by means of a nut 4. Along the circumference lo, an air gap 11 is formed between a collar on the inner flange 3 and a wall 7 on a shaft-lying air chamber. In the slot, blades 8 are provided which are secured to the collar of the rotor flange 3. The blades 8 extend substantially axially and communicate a tangential velocity component V 1 through the outlet air flow through the slot 11 due to the rotation of the blades.
Fig. 3 viser en anden udformning af luftindblæsningen. Luftspalten 11 er placeret mellem to kraver på luftkammer-væggen 7 og i spalten er der anordnet skråtstillede skovle 9.FIG. 3 shows another embodiment of the air supply. The air gap 11 is located between two collars on the air chamber wall 7 and in the gap there are inclined vanes 9.
Fig. 4 viser et snit langs AA i fig. 2, hvor det ses, at skovlene 8 forløber i hovedsagen aksialt, medens fig. 5 viser et snit langs BB i fig. 3, hvor det ses, at skovlene 9 er skråtstillet i forhold til rotoraksen.FIG. 4 shows a section along AA in FIG. 2, where it is seen that the blades 8 extend substantially axially, while FIG. 5 shows a section along BB in FIG. 3, where it is seen that the vanes 9 are inclined with respect to the rotor axis.

Ved udformningen ifølge fig. 2 opnår man den fordel, at den tangentiale hastighedskomponent ikke alene sammenfalder i retning med, men tillige i størrelse med omkredsfladens hastighed ud for det pågældende sted i spalten. Desuden kan det for lejet 6 nødvendige lejehus udnyttes som luftkammer, hvilket gør kammeret lettere at renholde under driften.In the embodiment of FIG. 2, the advantage is obtained that the tangential velocity component not only coincides with the direction, but also in size with the speed of the circumferential surface next to the point in the gap. In addition, the bearing housing needed for the bearing 6 can be utilized as an air chamber, which makes the chamber easier to clean during operation.
Ulempen ved denne udformning er, at der nødvendigvis må være et vist spillerum mellem skovlene og kraven på luftkammervæg— gen. Den gennem spillerummet fremførte luft kan danne utilsigtede hvirvler. Den på fig. 3 viste udførelsesform har ikke denne ulempe og muliggør lettere end den første udformning en variation i den tilførte luftmængde langs spalten, således at der f. eks. ved tilførslen af smelte tilføres mindre luft for at undgå en for stærk afkøling.The disadvantage of this design is that there must necessarily be some clearance between the blades and the collar on the air chamber wall. The air conveyed through the game room may form unintended whorls. The FIG. 3 does not have this disadvantage and facilitates a variation in the amount of air supplied along the gap easier than the first embodiment, so that, for example, when the melt is supplied, less air is supplied to avoid excessive cooling.
Ved fremgangsmåden ifølge opfindelsen er der fremstillet en bindemiddelholdig varmeisolationsplade med rumvægt på 29 kg/m^. Bindemiddelholdige mineraluldprodukter er de mest almindelige. I sådanne produkter er mineralfibrene fast forbundet med hinanden i de punkter, hvor de berører hinanden, ved hjælp af små ansamlinger af bindemiddel. I pågældende varmeisolationsplade var bindemidlet fenolharpiks og det udgjorde 1,45% af produktets vægt. Trækstyrken for denne 2 varmeisolationsplade var 11,o kN/m . Til sammenligning opviste en varmeisolationsplade med samme rumvægt og bin- demiddelindhold, fremstillet ved kaskadespinderproces som 2 tidligere kendt, en trækstyrke af størrelse 6,3 kN/m .In the method according to the invention, a binder-containing heat insulation plate having a room weight of 29 kg / m 2 has been produced. Binder-containing mineral wool products are the most common. In such products, the mineral fibers are firmly connected to each other at the points where they touch each other, by means of small aggregates of binder. In the thermal insulation board in question, the binder was phenolic resin and constituted 1.45% of the weight of the product. The tensile strength of this 2 heat insulation plate was 11, o kN / m. In comparison, a thermal insulation plate with the same bulk weight and binder content, produced by the cascade spinning process as previously known, exhibited a tensile strength of size 6.3 kN / m.
