Abstract

The invention relates to a SLM powder recycling device and belongs to the technical field of additive manufacturing. The recycling device comprises a base, two support pillars, a powder dropping chamber, a powder dropping channel, a diffusion channel, a powder screening chamber, rotary powder screening scraping piece components, a screening net, a powder constraining channel, a powder collection channel, a powder collection box, a powder receiving drawer, a heating chamber, a controller, four universal wheels, a vacuum working chamber, a powder suction pipe I and a powder suction pipe II. Thediffusion channel, the powder dropping channel, the powder dropping chamber and the vacuum working chamber are fixedly formed above the powder screening chamber in sequence. The lower portion of the powder screening chamber is fixedly provided with the powder constraining channel, the powder collection channel and the powder collection box in sequence. The powder receiving drawer is arranged inside the powder collection box. According to the SLM powder recycling device, the powder screening process, the powder recycling process and the powder drying process are of integrated design and implemented synchronously in a closed environment; no flying dust can be generated; the defects that steps are complex, and long time is consumed are overcome; and screening efficiency, recycling efficiencyand drying efficiency of powder are remarkably improved.
