Problems solved by technology

[0003] (1) Recycling and screening use independent equipment, which cannot be processed in one stop, and needs to be switched between different equipment. The powder is directly exposed to the air, there is a risk of oxidation and explosion, and there is a health hazard to the human body;
[0004] (2) Mesh screening technology can only remove large particles, and does not work for extremely small 3D printing spatters;

Embodiment 1

[0054] Embodiment one: the new powder inlet 40 is arranged on the connecting pipe between the cyclone separator 10 and the recovery cylinder 20 or the recovery cylinder 20, the new powder enters the recovery cylinder 20, and the screw rod of the powder mixer 50 located in the recovery cylinder 20 turns the new powder into the recovery cylinder 20. The powder and recovered powder are mixed, and then enter the screening device 30 together to screen out large particles.

Embodiment 2

[0055] Embodiment two: if figure 1 , figure 2 As shown, the new powder inlet 40 is set on the mixing tube 51 of the recovery cylinder 20 and the screening device 30, the new powder enters the mixing tube 51, the mixing tube 51 is connected with the powder mixer 50, and the new powder and the recovered powder pass through the mixing tube 51 Enter the powder mixer 50 together, and enter the screening device 30 together after being mixed by the powder mixer 50, and screen out large particles.

Embodiment 3

[0056] Embodiment 3: The new powder inlet 40 is arranged on the screening device 30, the new powder directly enters the screening device 30, and the recycled powder also enters the screening device 30, and the new powder and the recycled powder are mixed in the screening device 30 and large particles are screened out.

Abstract

The invention discloses a metal 3D printing one-stop powder recovery and purification device and a method, and solves the problem of low powder recovery efficiency after traditional metal 3D printing.The recovery device comprises a cyclone separator communicating with a recovery sucking pipe and used for separating light impurities from recovered powder, a recovery cylinder communicating with thecyclone separator, a screening device for screening away large particles, and a new powder inlet formed between the cyclone separator and the screening device for feeding new powder. The recovery device greatly improves the powder recovery efficiency, saves the cost, and is suitable for various machine types on the market.

Description

technical field [0001] The invention relates to a metal 3D printer, in particular to a metal 3D printing one-stop powder recovery and purification treatment device and method. Background technique [0002] At present, the main reason for the high cost of metal 3D printing is that the price of metal powder is relatively high. The cost of metal powder used to manufacture parts of the same size is higher than that of traditional processing methods. At the same time, the utilization rate of powder is low and cannot be reused, resulting in waste. serious. The powder processing of existing metal 3D printers generally includes several steps of "taking out the printed part - collecting excess powder - sieving powder - collecting". For powder processing equipment, the recovery and sieving of powder needs to be done manually, and frequent switching between various intermediate devices or containers makes the entire powder processing process take up to 5 hours or more. In addition, s...
