DEVICE FOR PRODUCTION OF FIBER AEROSUSPENSION FROM FIBROUS MATERIAL Russian patent published in 2003 - IPC

FIELD: pulp-and-paper industry; applicable in production of paper by aerodynamic method. SUBSTANCE: device has cylindrical body with channel for water intake, channel for fibrous material supply and outlet channel. Axially accommodated in body are stator and rotor. Rotor is made in form of two disk members with blades located between them. Blades are oriented mainly in radial direction. Rotor blades are installed so that annular cavity is formed between stator and rotor blade external edges. Said annular cavity is communicated through channels or holes of stator with air intake channel and through one or several branch pipes, with channel for intake of fibrous material. Formed behind rotor blade internal edges is central cavity communicating with device outlet channel. EFFECT: provided separation of material into fibers with formation of uniform flow of aerosuspension without swirlings and with required humidity. 7 cl, 10 dwg
