Abstract

Buluş, nozül üfleme yöntemine göre bir eriyikten (S) mineral yünün üretimine yönelik bir aygıt (1) için bir üfleme nozülü (5) ile ilgilidir. Üfleme nozülü (5), içinde eriyikten (S) en az bir birincil filamanın bir üflenen gaz akımı etkisiyle elyaflaştırıldığı bir nozül açıklığını (7) kendi aralarında sınırlayan karşılıklı iki nozül iç yüzeyi (22) içermekte olup; üfleme nozülünün (5) giriş bölgesinin (23) bir ucundan (8) üfleme nozülünün (5) bir çıkış ucuna (9) kadar nozül açıklığının (7) tüm uzunluğu üzerinden eriyiğin (S) en az bir birincil filamanı için, enjekte edilen gaz akımı için nozül açıklığı (7), içinde nozül açıklığının (7) bir kesitinin daraldığı bir ivmelenme bölgesine (16) ve içinde nozül açıklığının (7) kesitinin büyüdüğü bir yavaşlama bölgesine (17) sahiptir. Üfleme nozülünün (5) özelliği, ivmelenme bölgesi (16) ve yavaşlama bölgesi (17) arasında, içinde nozül açıklığının (7) kesitinin esasen sabit olduğu bir tutma bölgesinin (18) sağlanmasıdır.The invention relates to a blowing nozzle (5) for a device (1) for the production of mineral wool from a melt (S) according to the nozzle blowing method. The blowing nozzle (5) includes two opposing nozzle inner surfaces (22) delimiting between themselves a nozzle opening (7) in which at least one primary filament of the melt (S) is fiberized by the effect of a blown gas stream; The injected gas stream for at least one primary filament of the melt (S) over the entire length of the nozzle opening (7) from one end (8) of the inlet region (23) of the blast nozzle (5) to an exit end (9) of the blast nozzle (5) For this purpose, the nozzle opening (7) has an acceleration zone (16) in which a section of the nozzle opening (7) narrows, and a deceleration zone (17) in which the cross-section of the nozzle opening (7) becomes larger. The blowing nozzle (5) is characterized in that a holding zone (18) is provided between the acceleration zone (16) and the deceleration zone (17), in which the cross-section of the nozzle opening (7) is essentially constant.
