一种涤纶针织布预缩装置

Abstract

本申请提供了一种涤纶针织布预缩装置，涉及涤纶针织布技术领域,包括预缩加热箱，所述预缩加热箱的下方设置有蒸汽生成加热箱，通过设置的涤纶针织布预缩蒸汽回收组件，将水源添加至蒸汽生成加热箱的内部并通过蒸汽生成加热箱内置的加热部件对水源进行加热，水源加热后产生的蒸汽可通过蒸汽输送管道上升，并通过预缩加热箱底部开设有透气孔对针织布进行预缩，多余的蒸汽可进入蒸汽回流管道回流至蒸汽输送管道，蒸汽回流管道的内部设置有风机，可对蒸汽进行导向，可让蒸汽和凝结的水流进入至冷凝水回流管道的内部，定时控制电磁阀进行开启，可让水流通过冷凝水回流管道回流至蒸汽生成加热箱的内部，可让该装置不会出现浪费情况。
