APPARATUS FOR PRODUCING OF FIBROUS MATERIALS FROM THERMOPLASTIC MELTS Russian patent published in 2005 - IPC

FIELD: production of synthetic materials from thermoplastic substances and mixtures thereof, including high-quality industrial wastes, and also various kinds of domestic and industrial thermoplastic material wastes, in particular, may be used for producing of sorbents for catching of petroleum and petroleum products from water.

SUBSTANCE: apparatus has plate with detachable cover equipped with central opening where slider bearing for reactor shaft is mounted, inlet branch pipes adapted for feeding of melt into reactor and mounted within detachable cover, and rotating hollow reactor provided with spinneret and made in the form of truncated cone whose open part, that is, diverging cone and truncated cone of reactor are continuously joined to one another. Cylindrical rods having diameter D are serving as spinneret and spaced apart by equal gap L from each other to thereby allow separation of melt film into equal filaments of substantially equal cross-section D_i. Heater is made in the form of truncated cone and arranged coaxially to reactor in spaced relation thereto. Also, rear side of heater is protected by heat-insulating sleeve of refractory ceramics to facilitate maintaining of working temperature mode within reactor, provide predetermined temperature of melt film and substantially eliminate destruction thereof to thereby increase quality of resultant filament.

EFFECT: simplified construction, enhanced reliability in operation, improved quality of filaments and increased efficiency of reactor.
