Abstract

The invention discloses a device and method for separating mixed metal powder after 3D printing of a gradient material. The device comprises a feeding port, a fluid mechanics device and at least two material collecting boxes which are sequentially arranged in the falling direction of the mixed metal powder. The fluid mechanics device is provided with a plurality of longitudinally arranged air outlets; the air outlets are used for providing constant horizontal thrust for the mixed metal powder flowing out of the feeding port; the feeding port and the material collecting boxes are positioned atthe same side of the fluid mechanics device; the discharge end of the feeding port is arranged close to the top air outlet of the fluid mechanics device; and the material collecting boxes are arrangedclose to the bottom air outlet of the fluid mechanics device, arranged in the horizontal thrust direction at intervals and used for containing different kinds of powder. According to the device, magnetic or non-magnetic metal mixed metal powder with similar particle sizes can be subjected to high-precision separation.

Description

technical field [0001] The invention relates to the technical field of metal powder screening, and more specifically relates to a device and method for separating mixed metal powder after 3D printing gradient materials. Background technique [0002] With the rapid development of metal 3D printing technology (SLM, EBSM) additive manufacturing, the preparation of gradient materials by this method is favored by a wide range of scientific research scholars, enterprises and institutions. Usually, after the gradient material is prepared, there are more mixed metal powders of dissimilar metals around it and in the powder recovery device, but it is difficult to separate the mixed metal powders. [0003] At present, the traditional magnetic separation method and physical powder sieving method are usually used to separate mixed metal powders, but it is impossible to separate metal mixed metal powders that are magnetic or non-magnetic and have similar particle sizes. [0004] Therefor...
