Abstract

The invention is a method of producing glass fibre in which melted glass is fed into a hollow, rotating body and is then forced out through openings in the circumference of the body by means of centrifugal force. Outside the circumference, it is elongated to fine fibres by means of a gas blower or the like. The method is unique in that outside of or below the body (3, 4) with its openings, there is at least one inductive heater (6) that is supplied with a frequency of 50-4000 Hz.<IMAGE>

The method according to the invention is characterized in that the heater placed outside and / or below the loroppen with its openings and fed with a frequency of 50-4000 Hz. By this means a 'better' is obtained efficiency than in hitherto used procedures, a lower energy consumption and less reactive power demand, which also. is dependent on the simplicity of making the inductor single-speed, without requiring speed insulation. The inductor can thus be placed closer to the spinner. Man er- V nor the city's ease an evsmpa unwanted uppvsmsing 1 par- í horizontal construction parts, such as gas burners, shaft covers and the like.

Uppfinningar: går även ut på. en anordning, och det somkännetecknar anord- ningen framgår av nedanstående anordningslcrav.Inventions: is also based on. a device, and it which characterizes the device is stated in the device requirements below.

Uppfinningen är närmare exemplifierad i bifogad figur, som visar ett för- farande och en anordning för framställning av 'glasfibrein sett i genomskär- ning. hån en glassmältningsbehållare (ej visad) tappas glas 1 genom ett roterbart rör 5 ned till en fördelarkors' 3, roterbar tillsammans med röret 5 och in- gående i spinnaæen. Kring korgen är anordnad en centriing 4, och såväl korgen 3 som centrifugen 4 är försedd med sidoöppningar. vid rörets rotation komer glas att slungas ut genom sidoöppningarna i såväl korg 3 som centrifizg 4, och utanför centrifugen (via 4) near-ages fibrer men hjälp ev gesbläster (se vid pilarna 2), vilka för glasfibern nedåt. Kring den så. erhållna glas- fiberslöjan placeras kring och/eller nedanför eentrifugen en induktiv värmare 6, vilken enligt uppfinningen skall matas med en frekvens av 50-4000 Hz. Man tappar alltså. glas ner i centrifizgen, vilket på. sedvanligt sätt genom centri- mgalkraft sl1mgas ut genom sidoöppningar i korgen 3 och centrifugen 4, utan- för vilken det medelst glasbläster utdrages till fiber och föres ner som visas ' vid slöjan 7. Kring denna slöja 7 är anordnad en induktiv varmare 6, matad med en frekvens av 50-4000 Hz. Avsikten med värmaren är att värma korg och centri- fug samt att hålla. sidoöppningarna öppna och att hålla glasets temperatur hög.The invention is further exemplified in the accompanying figure, which shows a and a device for producing glass fibers as seen in section ning. When a glass melting container (not shown) is dropped glass 1 through a rotatable tube 5 down to a distributor cross' 3, rotatable together with the tube 5 and walking in the spinnaæen. Around the basket is arranged a centriing 4, and both the basket 3 as the centrifuge 4 is provided with side openings. at the rotation of the tube comes glass to be ejected through the side openings in both basket 3 and centri fi zg 4, and outside the centrifuge (via 4) near-ages fibers but help possibly gesblast (see arrows 2), which move the fiberglass downwards. Around it then. obtained glass the fiber veil is placed around and / or below the centrifuge an inductive heater 6, which according to the invention is to be supplied with a frequency of 50-4000 Hz. MAN thus loses. glass down in the centri fi zgen, which on. in the usual way by centralizing power is exhaled through side openings in the basket 3 and the centrifuge 4, except for which it is extracted into fibers by means of glass blasting and brought down as shown ' at the veil 7. Around this veil 7 is arranged an inductive heater 6, supplied with a frequency of 50-4000 Hz. The purpose of the heater is to heat the basket and central fug as well as to hold. the side openings open and to keep the temperature of the glass high.

Anordningen enligt uppfinningen består som visas av ett centralt rör med en till denna fast ansluten korg 3 och centrifug 4, tillsammans utgörande spinna- ren. Kring spinnaren mynnar öppningar 8 för gasblästsrn (se pilarna 2), och kring och/eller nedanför centrimgen 3, 4 är anordnad en induktiv värmare, avsedd att matas med en frekvens av 50-4000 Hz. iii..The device according to the invention consists, as shown, of a central tube with a to this fixedly connected basket 3 and centrifuge 4, together constituting clean. Around the spinner open openings 8 for gas blowers (see arrows 2), and an inductive heater is arranged around and / or below the center rim 3, 4, intended to be fed at a frequency of 50-4000 Hz. iii ..

10 8-107085-6 Sättet och anordningen enligt uppfinningen ger bättre verkningsgrad, lägre energiförbrulming och mindre reaktivt effektbehov än hittills använda anord- ningar för glasfiberframställning av här nämnt slag. Genom möjligen att ut- föra induktom envarvig lcräves ej heller varvisolering, och man kan placera värmaren närmare spinn-aren. Verkningsgraden blir härigenom större. Förbätt- ringen käameteclcnas också. av lätthet att avekärma oönskad uppvärmning i näraliggande konstruktionsdelar, som gasbrännare, schaktkåpor o d. Vid hittills använda värmare vid glasfiberframställning har man matat induk- torn med en frekvens av 6-20 kHz eller 100-300 kHz, vilket medfört ovan nämnda nackdelar. Förfaringssättet och anordningen enligt ovan kan varieras på. mångahanda sätt inom ramen för nedanstående patentlcrav. PATENTKRAV8-107085-6 The method and the device according to the invention provide better efficiency, lower energy roasting and less reactive power requirement than hitherto used devices for fiberglass production of the type mentioned here. By possibly making the inductor one-turn, no-turn insulation is required either, and the heater can be placed closer to the spinner. This increases the efficiency. The improvement is also cäameteclcnas. of ease of shielding unwanted heating in nearby structural parts, such as gas burners, shaft covers, etc. In heaters used hitherto in glass fiber production, the inductor has been fed with a frequency of 6-20 kHz or 100-300 kHz, which has the above-mentioned disadvantages. The procedure and device as above can be varied. various ways within the scope of the following patentlcrav. PATENT REQUIREMENTS 1.
