Abstract
The present invention relates to a device used for preparing metal powder by a disk type atomizing method. The gotten metal powder is various spherical crystals from 40 mesh to 200 mesh. The metal powder produced by the device has the advantages of less energy consumption, simple technology, and greatly reduced production cost.
Description
The invention belongs to the centrifugal spray legal system and get the device of metal dust.
Metal comprises the part non-metal powder, because they in powder metallurgy or the application in alloy, require certain fineness.Therefore, the method for preparing metal dust in recent years has very big development, United States Patent (USP) 4,435,342 provide a kind of method for preparing metal dust, are about to melt metal and pour on a rotating disc, and liquid metal hits under action of centrifugal force on second rotating disc, obtain metal particle, but to the dish type that guarantees that this device can long-term operation, and cooling system is not mentioned GB2,010,924A also uses metal powder making by tray type atomization method, and a kind of metal atomization device is provided, and dish type is a spill, but adopt extremely complicated bushing type cooling body, the cooling rotating shaft.
Purpose of the present invention: a kind of device of metal powder making by tray type atomization method is provided, particular design the dispersion rotating disc, directly adopt the water cooling rotating shaft, designed the mechanical seal that water deflector cover (17) has reduced rotating shaft.Thereby adopt this device energy consumption little, and technology is simple, and cost can reduce greatly, and big of product quality is the spherocrystal of controlled granularity.
Use metal powder making by tray type atomization method, the dispersion impeller of rotation is the core that guarantees product quality and normal operation at a high speed, the dispersion rotating disc (2) of used herein peptizaiton is by dish (10) in the dispersion of particular design and disperse lower wall (11) to form, the geometry of this dispersion rotating disc guarantees that the liquid material radially flies out, can prevent that the liquid material from spilling or under certain rotating speed the low speed of material overflow.Respectively having graphite or other heat-barrier material (9) and (12) to be fixed in the top and bottom that disperse rotating disc disperses in the rotating disc, and link to each other with disperseing rotating disc block set (13), can guarantee to disperse the running of rotating disc under high speed like this, charging aperture (8) places and disperses on the rotating disc.Complicated bushing type cooling device is not adopted in the temperature control of rotating shaft, the present invention adopts direct cold water cooling rotating shaft, in order to prevent that rotating shaft is when the high-speed cruising, because of making cooling water, vortex that action of centrifugal force forms effectively to contact with rotating shaft, designing wing shape device with holes (19) near on the fixed cover on rotating shaft top now, it has formed block water plate and has produced torrent, has destroyed vortex and can guarantee that the water surface is steady, and rotating shaft is effectively cooled off.When the rotating shaft high-speed cruising, the sealing device of cooling water is than difficulty, and the present invention adopts the easy structure of double-sleeve type, water deflector cover (17) both can guarantee the operate as normal of rotating shaft and cooling water, can be without mechanically-sealing apparatus, thereby frictional force is little, kinetic equation loss is little.
In order to guarantee in the process of Metal Production particulate; prevent the generation of oxide; the present invention adopts and will be heated to the above nitrogen of melting point metal or other protective gas and be under the gas phase protection circle situation of concentric garden with metal liquid stream and enter the dispersion rotating disc simultaneously; the ceramic funnel that reality has adopted the strap clamp cover connects as molten metal discharging opening and dispersion rotating disc; be that metal liquid stream is by flow export (8) when beginning to flow down; just under the high temperature inert gas protection, enter the dispersion rotating disc simultaneously; so not only completely cut off air but also protected molten metal can be converted into spherocrystal preferably; and it is not oxidized; above-mentioned gas heating capable of circulation; reuse, said other protective gas of the present invention is the exhaust combustion gases of the rich CO of oxygen deprivation.
Be example with the preparation copper powder below, copper fusing back is maintained the temperature at 1300-1400 ℃ in smelting furnace (1), and preheating disperses rotating disc (2) to more than 1200 ℃, under 4000-5500 rev/min or higher speed, rotate, with the quantitative injecting feeding mouth of copper liquid (8), under powerful action of centrifugal force, copper liquid flow to the peripheral spout (15) of dispersion rotating disc rapidly to be emitted into drop at a high speed by the geometric figure of dispersion impeller, chance is cold in spray chamber (5) lining, and condensing naturally is spherocrystal.The particle diameter of product copper powder disperses the speed of rotating disc and the size of spout (15) horizontal section with what of feeding quantity, can freely control, to obtain distributing comparatively concentrated 40-200 purpose copper powder.
Dish (10) and dispersion lower wall (11) are to manufacture with graphite material in the dispersion of particular design of the present invention.
Fig. 1 is that cooling system 4-motor 5-spray chamber 6-blower fan (the cooling motor chamber is used) 7-that the schematic diagram 1-smelting furnace 2-of preparation metal dust disperses rotating disc 3-axle is incubated Gas Pipe.
Fig. 2 is that dish 11-disperses lower wall 12-heat-barrier material 13-to disperse the rotating disc block set in dispersion rotating disc 8-charging aperture-9-heat-barrier material 10-dispersion of designing of the present invention.
Fig. 3 is the dispersion rotating disc of particular design of the present invention, and it is gone up dish and disperseed lower wall to form the 15-spout by dispersion.
