Embodiment

[0060] The frame 20 is made of steel welded or bolted, and is connected to the ground through bolts; the material of the storage tank 17 is stainless steel, the typical size of the storage tank is Φ500mm*500mm, the diameter of the material inlet 8 is 100mm, and the diameter of the material outlet 18 is 50mm. The diameter of the air inlet 9 and the air outlet 11 is Φ8mm, and a quick-plug connector is reserved, which is connected to the corresponding solenoid valve through a hose; the detection port 4 is a standard industrial valve core with a diameter of 5mm, which can be connected to the oxygen sensor, thereby Quickly measure the oxygen content in the storage tank; the pressure gauge 5 is an industrial pressure sensor with a head, the maximum detection pressure is 500mbar, and the detection accuracy is 0.15%. The signal transmits the detection result to the central logic controller 16; the argon gas bottle is connected to the pressure reducing valve 2 to decompress the high-pur...

Abstract

The invention discloses a metal powder storage system and a using method thereof. According to the system, storage tanks in a discharging system is connected with inert gas, a vacuum pump and the atmosphere, micro-positive pressure environment can be ensured in the storage tank, compared with a vacuumized negative-pressure storage method, contact with air can be avoided more favorably, the systemis particularly suitable for long-term storage of metal powder such as titanium alloy, aluminum alloy and magnesium alloy which are easy to oxidize, according to the system, the plurality of storage tanks can be arranged according to actual requirements, various types of metal powder can be placed between different storage tanks, each storage tank is provided with a respective control valve so that the storage tanks can be independently controlled; and secondly, by adopting the storage tanks to store the metal powder, the metal powder of the same material can be added in batches at a time andcan be taken and used according to the quantity anytime and anywhere, so that the risk that after a vacuum fixed package is opened, redundant unused new metal powder repeatedly makes contact with theair and is polluted is avoided.

Description

【Technical field】 [0001] The invention belongs to the technical field of material storage, and in particular relates to a metal powder storage system and a use method thereof. 【Background technique】 [0002] Additive Manufacturing (AM) has been successfully applied in aviation, aerospace, medical, mold and other industries due to its fast, mold-free, free-forming, and ability to manufacture complex structures. Metal additive manufacturing has strict requirements on the quality of metal powders, especially for titanium alloy powders, aluminum alloy powders, and magnesium alloy powders with strong activity. use. In addition, for some light alloy metal powders, such as aluminum alloys and magnesium alloys, if they are improperly stored during storage, the powders will be suspended in the air and will explode when encountering an open flame, so there is a great potential safety hazard. The preparation process of metal powder involves multiple links such as smelting, rod making...
