3D printing titanium alloy member usually requires that the granularity of pre-alloyed powder less than 53 μm, has higher sphericity, together
When have strict demand to the impurity content of powder, by taking typical Ti-6Al-4V powder as an example, it is desirable that for 3D printing powder
Oxygen content is less than 1200ppm.However, the large specific surface area of titanium alloy pre-alloyed powder, powder particle surface is easy absorption air
In oxygen and the gases such as steam, thus two kinds of elements of bring oxygen and hydrogen can deteriorate the performance of titanium alloy, furthermore prealloy
Powder surface is such as stain because having adsorbed pernicious gas, will affect the overall performance of 3D printing component.
Therefore storage, transhipment and the encapsulation process of titanium alloy pre-alloyed powder become most important, safely and conveniently store
Titanium alloy pre-alloyed powder guarantees the surface quality of pre-alloyed powder, be titanium alloy 3D printing technique acquisition well develop it is necessary
The technical issues of solution.
Utility model content
The purpose of this utility model is to provide a kind of vacuum titanium alloy powder storage device, which can be in vacuum ring
Titanium alloy pre-alloyed powder is safely and conveniently stored in border, guarantees the quality of pre-alloyed powder.
To achieve the goals above, the technical solution of the utility model is:
A kind of vacuum titanium alloy powder storage device, the device include holding vessel, vacuum pump set and vacuum degassing pipe；Its
In: it is connected between the holding vessel and vacuum pump set by vacuum degassing pipe.
The holding vessel includes the tank body and upper cover of upper end opening, and upper cover and Cap for tin body form closed inner cavity after closing；Institute
Inner cavity is stated for storing titanium alloy powder.
Conjunction is opened and covered between the upper cover and tank body by circlip.
Handle is additionally provided on the outer edge of the upper cover, the handle is corresponding with the position of the circlip；Lifting downwards
Upper cover is opened when handle, closes upper cover lid on tank body when pressing down on handle.
The outer edge of the upper cover is equipped with sealing ring, so that upper cover lid closes when on tank body, improves the airtightness of inner cavity.
Vacuum meter, vent valve and observation window are additionally provided on the side wall of the tank body, in which: the vacuum meter is for monitoring institute
State the vacuum degree of inner cavity；The vent valve is used to be put into gas to inner cavity；The observation window can be used for observing powdered in inner cavity
State.
It is additionally provided with flange on the side wall of the tank body of the holding vessel, is connected between holding vessel and vacuum degassing pipe by flange
It connects.
The vacuum pump set includes vacuum pump (the air-cooled vacuum pump of rotary vane type), passes through method between vacuum pump and vacuum degassing pipe
Orchid is connected.
The both ends of the vacuum degassing pipeline are equipped with sealing ring.
The utility model has the advantages that
1, the utility model provides one relatively for titanium alloy pre-alloyed powder primarily directed to the storage of titanium alloy powder
The environment of vacuum, thus avoid in air oxygen and the gases contact metamorphism such as steam.
