Abstract

The invention relates to a titanium alloy tiny powder gas screening device which comprises a closed container (1). A powder feeding opening (2) is formed in the top of the closed container (1). A rough powder outlet (3) and a fine powder outlet (4) are formed in the bottom of the closed container (1). A funnel-like screen (5) is arranged in the closed container (1). A sleeve (6) with a hole formedin the surface is arranged on the inner side of the funnel-like screen (5). An inert gas input opening (7) is formed in the top end of the sleeve (6). A motor (8) is connected with and drives the sleeve (6) to rotate. The closed container (1) is further provided with a gas exhausting opening (9). Inert gas is adopted for generating corresponding circulating airflow, no residual powder exists on the surface of the screen all the time, the situation that the powder gathers on the surface of the screen, and the screen is blocked is avoided, the screening efficiency is reduced, screening is uniform, safe and efficient, meanwhile, the screen does not need to be replaced frequently, and the device is simple and easy to use.

Description

technical field [0001] The application belongs to the technical field of 3D printing powder screening, and in particular relates to a titanium alloy fine powder gas classifier. Background technique [0002] In the sieving process of 3D printing powder, especially for titanium alloy fine powder, it is difficult to complete the sieving with traditional sieves. The powder can easily block the mesh of the sieve, making the sieving efficiency extremely low. And because the fine powder of titanium alloy has the risk of being extremely flammable and explosive, ordinary airflow screens cannot be used as suitable screening tools due to the use of air as power and insufficient sealing. [0003] As the prior art relates to a screening device, including a feeding assembly, a screening assembly and a vacuum feeding assembly, the screening assembly includes a grid frame, a screen main body and a guide, and the screen main body is installed on the net In the rack, the guide has a first o...
