DEVICE FOR MANUFACTURE OF FILMS AND FIBRES OF CELLULOSE AND INTEGRATED EQUIPMENT FOR MANUFACTURE OF FILMS AND FIBRES Russian patent published in 2000 - IPC

FIELD: device with integrated equipment for manufacture of films and fibres of cellulose by the amine oxide method. SUBSTANCE: the major components of the device equipment are an apparatus for production of cellulose, mixer (B, B') intended for preparation of low-consistent cellulose suspension in an aqueous solution of amine oxide, as well as an apparatus (C) for concentration of low-consistent cellulose suspension. In apparatus (C) the cellulose suspension is mechanically distributed in the form of a layer over the heating surface, gets heated and moves over this heating surface at an intensive agitation and evaporation of water up to evaporation of the preset amount of water and production of concentrated cellulose suspension. In apparatus (D) the concentrated cellulose suspension obtained in apparatus (C) gets transformed in a moulding apparatus connected to apparatus (D) cellulose films or fibres are manufactured from moulding cellulose solution. EFFECT: continuous process of production of films and fibres. 14 cl, 2 dwg, 1 ex
