Abstract

A kind of carbon fiber precursor stretching cleaning equipment, it includes steel welded base, stainless steel material stretching roller unit is installed above the base, solidification bath tank, hot water tank and oiling tank are fixed below stretching roller above the base, the right side of the base above stretching roller unit is equipped with wire collecting auxiliary unit, wire collecting roller unit is installed above the base and right side of wire collecting auxiliary unit, the left side of the base above stretching roller unit is equipped with spinning pump, the present application is novel in structure, simple structure, high integration, small space occupation, strong adaptability, easy to operate to replace the original carbon fiber precursor relies on steam boiler high temperature stretching filament bundle process action.Due to solidification bath in the process of drawing, washing, oiling, so reaction temperature is lower, and using electric heating roller, compared with the heating method of traditional carbon fiber production process using steam boiler is more energy-saving.
