Description
Technical field
The utility model relates to alloy powder vertical gas atomising device.
Background technology
Gas atomization is widely used in the preparation of metal or alloy powder, and powder by gas-atomization is by high speed stream of nitrogen gas impact grinding metal or alloy liquid stream, liquid stream is broken into the milling method of fine droplet.
Nozzle is to make atomizing medium obtain high-energy, high-speed parts in the atomising device, and it plays an important role to the stability of nebulization efficiency and atomization process.Present nozzle has free fall style nozzle and restraint-type nozzle, its shortcoming that has is: in atomization process, by a jet atomization, the alloy fluidization tower becomes alloy liquid droplet not of uniform size and particle, because a gas jet thermal capacity is little, make many bulky grain drops have little time to solidify, in flight decline process, particle takes place to contact frequently with drop, and particle is attached on the drop, and the cooling back forms satellite ball powder, the big drop of part freely disintegrates in the decline process, be easy to generate the hollow ball powder, cause the alloy powder state irregular, tissue homogeneous degree is poor.
The utility model content
The purpose of this utility model is to propose a kind of alloy powder vertical gas atomising device of even tissueization, and it can solve the problem of tissue homogeneous degree difference.
In order to achieve the above object, the technical scheme that adopts of the utility model is as follows:
A kind of alloy powder vertical gas atomising device of even tissueization, it comprises be used to the container of depositing alloy solution, is installed in the built up nozzle of described container bottom, is positioned at the fire-resistant cover at built up nozzle middle part, magnetic valve and controller; Described built up nozzle comprises stacked and fixedly connected mutually top nozzle, following nozzle, described nozzle down has the following spray orifice of a plurality of realization conical jets, described top nozzle has the last spray orifice of the annular parallel injection of a plurality of realizations, last spray orifice is positioned at the periphery of spray orifice down, and last spray orifice, following spray orifice all are connected with a nitrogen conveying equipment; Described container bottom offers one and lets slip a remark, and in described magnetic valve was installed in and lets slip a remark, magnetic valve and controller electrically connected; The middle part of described fire-resistant cover offers a through hole, and described through hole is communicated with leting slip a remark.
Preferably, the injection angle of a plurality of spray orifices down formation is 65-80 °.
The utlity model has following beneficial effect:
Reduced satellite ball powder and hollow ball powder, the bulk density of powder is improved, the even tissueization of alloy powder is good.
