Technical Problem
该方式是采用管道内气力输送的方式将设备产生的待筛粉末收集到集中筛粉处理站去处理，需要布置输送管道，对设备的尺寸和现场布局有较高的要求，此外，粉末流转过程较长，流转机构复杂，容易造成粉末的浪费和污染，粉末的流转效率低，需要积累一定量的粉末才能进行集中处理
Benefits of technology
[0018]本实用新型提供了一种粉末循环系统，包括溢粉回收漏斗、滤除设备以及粉末输送设备；溢粉回收漏斗通过滤除设备与粉末输送设备相连通。本实用新型通过溢粉回收漏斗将收集到的未参与成形的粉末以及成形过程中所形成的黑渣经过滤除设备进行筛选分离，将未参与成形的粉末经过粉末输送设备后送至增材制造设备的落粉桶中并参与后续的继续成形，形成内置式粉末循环。本实用新型结构简单，整体故障率低，可集成在现有增材制造设备，能避免打印设备需要连接外置式粉末循环系统安装的一系列管道、通讯线、气源管路等，具备粉末循环功能的同时也提高了现场整洁度，大幅提高了工作效率。同时，本实用新型所采用的粉末输送设备，使得粉末循环过程短，能及时的将已处理的粉末供应到打印设备，提高了粉末流转率，很大程度上避免了粉末的污染。
