新型丝束烘干辊的研发与应用

Development and Application of the New Tow Drying Roller

对目前常用的夹套式、虹吸式两种丝束烘干辊的结构及存在的问题进行了详细的分析;并参考两种结构的优点,研发出了一种新型丝束烘干辊并对其结构特点及应用效果作了探讨。该新型丝束烘干辊具有以下特点:结构比较简单,安装维护方便,保温效果好,辊体高速运转时辊面跳动小,而且环形腔内不易存留积水,在保证辊面温度的同时有效节约了饱和蒸汽的使用量,从而降低了生产成本,也提高了生产的连续性和稳定性。该新型丝束烘干辊已经在特种纤维生产线上得到了很好的应用。

Comprehensive analysis is done to the structure of the commonly-used tow drying rollers ot Down clip type and siphon type in addition to the related problems. Combined with the advantages of the above- said tow drying roller,a new tow drying roller is introduced with the approach into the structure and the application effect. The advantages of the new tow drying roller are as follows：simple structure, easy instal- lation, good insulation, small water accumulation with speedy roller, and more, the ring cavity is not liable to accumulate water, consequently the consumption of the saturated steam is reduced with the desired roll- er temperature. The production cost is reduced and the continuity and stability of production maintained. The above-said tow drying roller has been widely used in the production of the special fiber.
