Abstract

The invention discloses a high-temperature high-pressure plasticizing device which comprises a high-pressure stainless steel shell, wherein a through cavity is defined in the high-pressure stainless steel shell, end glands are arranged outside the end tips of the two ends of the through cavity, the part of the high-pressure stainless steel shell, corresponding to the bottom part of the middle part of the through cavity, is provided with an air inlet, the parts of the high-pressure stainless steel shell, corresponding to the bottom parts of the two ends of the through cavity, are provided with air outlets, the middle part in the through cavity is provided with an intake pressure uniform distributor communicated with the air inlet, the two end parts in the through cavity are provided with pressure relief exhaust distributors communicated with the air outlet, labyrinth seal assemblies are arranged between the intake pressure uniform distributor and the pressure relief exhaust distributors and between the pressure relief exhaust distributors and the end glands, the centers of the labyrinth seal assemblies and the end glands are provided with silk holes. By the adoption of the high-temperature high-pressure plasticizing device, the air flow compact on processed chemical cellosilk bundles can be reduced greatly and vibration quantity is lowered; meanwhile, steam leakage rate at pressure relief ends and the silk holes can be reduced effectively, internal pressure guarantee of the cavity is met, the distribution gradient of pressure and temperature in the cavity is realized.

Description

technical field [0001] The invention relates to a plasticizing device, in particular to a high-temperature and high-pressure plasticizing device, which belongs to the technical field of chemical fiber spinning preparation, and is especially suitable for realizing high-stretching function in the production of carbon fiber precursors. Background technique [0002] In the process of chemical fiber preparation, it is necessary to perform high-strength stretching in the final process section to increase the orientation degree of the fiber molecular chain, thereby improving the mechanical properties of the fiber. The equipment that realizes this process is called a high-temperature and high-pressure plasticizing device. The device is a high-temperature and high-pressure chamber through which chemical fibers pass to achieve high-strength stretching under high temperature and high pressure. Especially when preparing high-performance carbon fiber precursors, the process requirements ...
