FIBROUS MATERIAL WASHING APPARATUS Russian patent published in 1999 - IPC

FIELD: textile industry. SUBSTANCE: washing apparatus has conveyor for feeding fibrous material preliminarily loosened on scutching machine to hopper, where fibrous material is wetted by spray beam delivered from nozzle. Fibrous column is compacted and fed to carding drum for discretization of yarns and removal of organic, mineral and plant contaminants. Preliminarily cleaned complexes are passed above pallet for removal of contaminants. Apparatus is further provided with roll for removing fibrous material from drum and throwing it onto conveyor. Fibrous material is washed with washing solution spray beam in zone between conveyor carrier run and nozzle. Fibrous material layer saturated with washing agent is supplied into microwave field working zone between conveyor and wave guide. Microwave energy is emitted from wave guide to fibrous layer so as to penetrate through it and excite it at atomic and molecular level. Microwave field activates microparticles of aqueous-fibrous mixture to excited state, which is displayed by fast heating of mixture. Heat and related electric factors facilitate disintegration between fibers and organic contaminants, with viscosity of organic contaminants suddenly decreasing. Portion of fatty substance drips into tank. Final washing out of contaminants is accomplished by washing solution spray beams delivered by nozzles. Used solution drips into tank from which it is delivered into soaking nozzle. Cleaned fibers are fed to roll tips and discharged from apparatus. Used solutions are supplied from tank to settlers for further processing and recycling. EFFECT: increased efficiency and improved quality of cleaned fibrous material. 1 dwg
