A kind of titanium alloy powder screening device

Abstract

The invention provides a titanium alloy powder screening device and relates to the technical field of 3D printing powder screening production. The titanium alloy powder screening device comprises a screening box body, the screening box body is in a hollow cylinder shape, and a material storing and discharging device and a screening and collecting device are arranged in the screening box body fromtop to bottom. The material storing and discharging device comprises a material barrel. A left rotating shaft and a right rotating shaft are symmetrically arranged on the outer wall of the material barrel, and the material barrel is rotationally connected to the inner wall of the screening box body through the left rotating shaft and the right rotating shaft. A feeding hose is arranged on the topof the material barrel, the inlet end of the feeding hose penetrates through the top of the screening box body to the exterior of the screening box body, and a step pipe is arranged at the bottom of the material barrel. The step pipe communicates with the interior of the material barrel, multiple buffering inner cavity plates are evenly distributed on the inner wall of the screening box body in the circumferential direction, and the buffering inner cavity plates are in a hollow arc shape. The titanium alloy powder screening device has the beneficial effects that titanium alloy powder can be screened in a multi-stage manner, the screening effect is improved, and the blocking phenomenon in the screening process can be prevented.

Description

technical field [0001] The invention relates to the technical field of 3D printing powder screening production, in particular to a titanium alloy powder screening device. Background technique [0002] As the most cutting-edge and most potential technology in the entire 3D printing system, metal 3D printing technology is an important development direction of advanced manufacturing technology. The fluidity and uniformity of titanium alloy metal powder are the key properties of powder materials used in 3D printing technology. In order to ensure the purity of the titanium alloy metal powder, a sieving step is required to separate the large particle size metal powder mixed in the powder. [0003] At present, most of the sieving devices make the titanium alloy powder fall directly to a single or multiple fixed sieves or sieve plates for sieving, which makes it easy to cause blockage during sieving. The screen needs to be replaced many times, which increases the labor cost, and t...

Problems solved by technology

[0003] At present, most of the sieving devices make the titanium alloy powder fall directly to a single or multiple fixed sieves or sieve plates for sieving, which makes it easy to cause blockage during sieving. The screen needs to be replaced many times, which increases the labor cost, and the screening effect will be greatly reduced due to the easy clogging during screening, which requires further improvement of the screening device
