Abstract

The invention relates to a metal powder mixing device and method and a high-throughput metal alloy preparing system. The metal powder mixing device comprises a cylinder and a metal powder carrier gaspipeline. A metal powder carrier gas inlet is further formed in the side wall of the upper end of the cylinder. The metal carrier gas pipeline is parallel to the tangential direction of the side wallof the cylinder. Metal powder and carrier gas can form carrier gas carrying metal powder after passing through the metal powder carrier gas pipeline, the formed carrier gas enters the cylinder from the metal powder carrier gas inlet at a constant speed, and annular turbulent flow is formed in the cylinder to be mixed and scattered. In the metal powder mixing method, the carrier gas carrying metalpowder enters the cylinder and forms the annular turbulent flow, and therefore the probability of metal powder colliding is improved, and the metal powder mixing efficiency is further improved. By means of the high-throughput metal alloy preparing system, metal powder mixed evenly through the metal powder mixing device can be machined, and a needed metal alloy can be more accurately obtained.

Description

【Technical field】 [0001] The invention relates to the field of metal 3D printing, in particular to a metal powder mixing device and method thereof, and a high-throughput metal alloy preparation system. 【Background technique】 [0002] Metal 3D printing is a technology based on digital model files, using powdered metal as a bondable raw material, and constructing objects by layer-by-layer printing. In the prior art, two kinds of metal powders are generally fed successively during the printing process of the additive manufacturing equipment for printing, so as to form gradient materials when preparing samples. However, in the prior art, the quantitative ratio of the components of different metals cannot be carried out, and the preparation of special bulk alloy materials, especially the design components, cannot be satisfied. [0003] Furthermore, when the metal powder is mixed, due to the difference in the particle size and density of the metal powder, the metal powder is ofte...
