Abstract

The invention relates to a fiber pressure-retaining drawing device under pressurized steam. The drawing device comprises a drawing cavity, wherein, a feeding steam seal component, a preheating drawing cavity, a middle steam seal component, a heating drawing cavity and a discharging steam seal component are sequentially arranged in the drawing cavity along the advancing direction of filament bundle; the preheating drawing cavity is equipped with a steam preheating pipe for providing steam to the preheating drawing cavity; the heating drawing cavity is equipped with a steam heating pipe for providing steam to the heating drawing cavity; a steam preheating chamber is arranged in the middle part outside the preheating drawing cavity, the wall of the preheating drawing cavity is made of a porous material, and the steam preheating chamber is communicated with the steam preheating pipe; and a steam heating chamber is arranged in the middle part outside the heating drawing cavity, the wall of the heating drawing cavity is made of a porous material, and the steam heating chamber is communicated with the steam heating pipe. By utilizing the fiber pressure-retaining drawing device, the technical problem of the existing fiber drawing device under the pressurized steam that the internal pressure can not meet the technological requirement is solved, and broken filaments caused by up-down vibration of the filament bundle are avoided so that the internal pressure and temperature of the drawing cavity reach a constant state.

Description
