Description
Technical field
The invention belongs to the technical fields of powder metallurgy, specifically disclose a kind of metal powder oxidation.
Background technology
Powder metallurgy is to take the mixture of metal powder or metal powder and non-metal powder as raw material, by forming
And sintering, produce the industrial technology of metal material, composite material and various types product；And metal powder injection molding is mesh
Before a forming technique quickly growing, there are the small parts and each position density of product that can form arbitrarily complicated shape
The good advantage of uniformity.Since powder metallurgy has strict requirements to the fineness of metal powder, also to ensure metal powder not by
Oxidation, so most metal powders are all made of being ground by the way of wet-milling, and the medium of wet-milling is mostly alcohol.
Since the very high and different metal physicochemical property of the fineness of metal powder is also different, such as titanium metal powder, although will not be by wine
Essence oxidation, but it can be hydrogenated with Ethanol Exposure for a long time.So these metal powders are aoxidized or are hydrogenated in order to prevent, after ball milling
Metal powder can be dried immediately, but for some metals, heat drying can aggravate its oxidation, hydrogenation instead
Process.
Publication No. CN106964433A discloses a kind of anti-oxidation ball mill；Including rack and cylinder, it is placed in cylinder
Several mill balls are rotatablely equipped with shaft in rack, and the cylinder is installed in shaft, and cylinder is equipped with input and output material
The top of material gate, rack is equipped with holder, is installed with cross bar at the top of holder, material bin is movably installed on cross bar, horizontal
Inertia hammer is installed on bar, material bin bottom is provided with more equipped with the inner wall with the matched discharge door of material gate, material bin
Group is looped around the skewed slot of material bin inner wall；Skewed slot opening tilts upward, and sodium nitride powder is housed in skewed slot.The program utilizes nitridation
The nitrogen that sodium powder end generates after hitting is anti-oxidation to carry out, still, if sodium nitride powder has been infiltrated in metal powder, follow-up
In sintering process, sodium nitride powder is difficult to remove, and leads to metal material quality degradation.
Invention content
The purpose of the present invention is to provide a kind of metal powder oxidations, make metal powder more to solve heat drying
The problem of being oxidized easily.
In order to achieve the above object, base case of the invention is：Metal powder oxidation, including rack and drying
Case, the drying box are arranged in rack, further include drier, and the drier includes horizontally disposed and is mutually parallel
It receives cloth cylinder and puts cloth cylinder, the receipts cloth cylinder and put the both sides that cloth cylinder is located at drying box, and receive cloth cylinder and put cloth cylinder and rotate
It being connected in rack, the receipts cloth cylinder, which is equipped with, absorbs cloth, absorbs one end of cloth and to receive cloth cylinder affixed and be wrapped in and receive on cloth cylinder,
It absorbs the other end of cloth and puts that cloth cylinder is affixed and be wrapped in and put on cloth cylinder, and the side wall of the drying box is equipped with straight slot, the suction
It receives cloth to extend into drying box across straight slot, the absorption cloth is equipped with several block-like grids, between two neighboring grid
Distance is more than the length of drying box.
The operation principle of this base case is：The good metal powder of ball milling is gradually passed into drying box, rotation is received
Cloth cylinder puts cloth cylinder, and receiving cloth cylinder at this time or putting cloth cylinder gradually to collect absorption cloth winding, and absorbing cloth can be constantly from dry
It is passed through in dry cylinder.When metal powder, which is flow to, to be absorbed on cloth, absorbing cloth can quickly absorb liquid medium, that is, alcohol therein.
After absorbing in the Grid Mobile to drying cylinder in cloth, metal powder can drop into the bottom of drying box from grid.
The advantageous effect of this base case is：Alcohol is absorbed using cloth is absorbed in this programme, and absorbs cloth continuous
Ground moves, so metal powder can be contacted with dry absorption cloth always, the alcohol in metal powder is enable all to be absorbed,
Metal powder is effectively prevented by too fast oxidation.When absorbing cloth movement simultaneously, the metal powder above it can be driven by absorbing cloth
It is mobile, so that the alcohol in metal powder is absorbed more quickly.The mode that heating is not used in this programme carries out metal powder
It is dry, but can have the function that prevent oxidization of metal powder.
Further, the drying box sealing, drying box are equipped with inlet valve and outlet valve, argon gas are loaded in drying box.
Using this programme, after drying box sealing, outside air cannot be introduced into, and ensures metal powder and oxygen-barrier, prevents metal powder
Oxidation.And argon gas belongs to inert gas, property is stablized, and will not react with metal powder.
Further, further include driving mechanism, the driving mechanism includes pressing plate and communicating pipe, and the pressing plate is slidingly sealed
In drying box, on pressing plate affixed connection be equipped with discharge nozzle, the lower end of discharge nozzle is connected to outlet valve, one end of the communicating pipe and
The bottom of drying box is connected to, and heating device is equipped in communicating pipe, and the other end of communicating pipe is equipped with the first branch pipe and the second branch pipe, the
One branch pipe is equipped with the first solenoid valve, and the first branch pipe is rotatablely connected and is connected to receipts cloth cylinder, is connected with one heart in the receipts cloth cylinder
The first impeller of cloth cylinder rotation is received in energy drive, and second branch pipe is equipped with second solenoid valve, and the second branch pipe is rotated with cloth cylinder is put
Be connected to and in communication with, it is described put be connected with one heart in cloth cylinder can drive receive cloth cylinder rotation the second impeller, the receipts cloth cylinder with put cloth
It is equipped with leakage hole on cylinder.Using this programme, after metal powder is fallen on pressing plate, with the increase of metal powder, pressing plate can be held
It is continuous to move down, and argon gas was pressed into communicating pipe.Open the first solenoid valve, argon gas, which can enter, receives cloth cylinder, and argon gas can drive the
One wheel rotation is rolled so receiving cloth cylinder and can will gradually absorb cloth, and absorbing cloth can move in drying box.Finally, argon gas
It can be leaked out from the leakage hole for receiving cloth cylinder, the absorption cloth due to receiving the retracting of cloth cylinder absorbs a large amount of alcohol, so working as argon gas from leakage
The alcohol absorbed on cloth can be blown away after being leaked out in hole.Heating device on communicating pipe can heat argon gas, after heating
Argon gas by leakage hole with absorb after cloth contacts, so that the alcohol on absorption cloth is volatilized.It has been furled when absorbing cloth
Afterwards, second solenoid valve is opened, the first solenoid valve is closed, argon gas is put in cloth cylinder from being flowed into the second branch pipe, puts cloth cylinder at this time and open
Beginning receives cloth, since the absorption cloth that argon gas will be received on cloth cylinder is all dry, so when absorption cloth is again introduced into drying box, absorbs
The state that cloth is still dried can absorb alcohol again.
Further, the bottom of the pressing plate is equipped with elastic component, and the bottom of elastic component and the bottom of drying box are affixed.Using this
Scheme, after metal powder is released from outlet valve, elastic component can be resetted with dynamic pressure plate.
Further, the both ends of the straight slot are equipped with seal gasket.It can prevent metal powder from straight slot using this programme
It drops out.
Further, further include expansion box, argon gas is loaded in the expansion box, expansion box is connected to the upper end of drying box.
Using this programme, when pressing plate moves down, gradually forms negative pressure above pressing plate and absorb new argon gas out of expansion box.
