Dryer system for high-strength high-modulus superhigh molecular weight polyethylene fibers

Abstract

The invention discloses a dryer system for high-strength high-modulus superhigh molecular weight polyethylene fibers, which comprises a mixer, a heater, a dryer, an induced fan and an air blower, wherein the mixer, the heater, the dryer and the induced fan are sequentially connected and form a circuit; the air blower is respectively connected with the induced fan and the mixer through valves; thevent capacity of air entering the air blower is 10 to 30 percent; and a drive roll in the dryer is fixed by two sides. The dryer system circularly uses hot air, pre-dries wet filaments and fulfils the aims of saving energy and improving the tensile property of the filaments; meanwhile, the bending moment of the filament to a driven roll of a drying oven is reduced, which is favorable for protecting equipment and maintaining stable production; and the system pressure is easily adjusted to be balanced and stable.

Description

Technical field [0001] The invention relates to a dryer, in particular to a dryer system for high-strength, high-modulus, ultra-high molecular weight polyethylene fibers. Background technique [0002] The existing dryer is composed of a blower, a heater, a drying box and an induced draft fan. The working method is that the blower sucks in fresh air and heats it to a predetermined temperature (30-100°C), then enters the drying box, transfers heat to the thread and takes it away The hot liquid is sucked and discharged outdoors by the induced draft fan. The disadvantage is that the hot air cannot be reused and energy is wasted. In addition, the wet thread does not have any processing measures before entering the dryer, resulting in a sudden increase in tension caused by the rapid volatilization of a large amount of liquid at the entrance of the dryer, which produces a large amount of wool, which affects the post-stretch performance of the fiber. Summary of the invention [0003] In ...

[0002] The existing dryer is composed of a blower, a heater, a drying box and an induced draft fan. The working method is that the blower inhales fresh air and heats it to a predetermined temperature (30-100°C), then enters the drying box, transfers heat to the filaments and takes them away. The hot liquid is then sucked and discharged to the outside by the induced draft fan. The disadvantage is that the hot air cannot be reused and energy is wasted

In addition, there is no process treatment for the wet filaments before they enter the dryer, resulting in the sudden increase of tension caused by the rapid volatilization of a large amount of liquid at the entrance of the dryer, resulting in a large number of fluff, which affects the post-stretch performance of the fibers
