With the development of powder metallurgy industry, the granularity requirements of feed metal powder are improved constantly.Metal injection into
In shape technique (MIM), the particle of powder used must be very thin, has high tap density and low oxygen content.In addition, in Buddha's warrior attendant
In lapicide's tool, the pre-alloyed powder as bonding agent just develops towards ultra-fine, hypoxemia direction.
Existing industrial milling method has a variety of at present, wherein most common and efficient method is water atomization pulverization, it is to make
The metal liquid stream melted with current high speed impact, so that the technique that metal liquid stream is broken into attritive powder.Due to water atomization
The powder size of manufacture is thin, and chemical composition is wide, and cost is low, suitable volume production, so water atomization is widely adopted.Water atomization pulverization
Technique includes：Dispensing, smelting, atomization, powder are dehydrated and closed batch, screening, are weighed, the post-processing step such as packaging, powder
It is relatively long to post-process flow.
After metal dust prepares generation, after powder drying in the post-processing that carries out, at present close batch, powder delivery,
The technical process such as screening, weighing and packaging mainly take powder after the completion of the mode that either simplex skill is sequentially separately handled, such as conjunction batch
Discharging, move to screening area, sieve the qualified powder finished and move into packaging area progress weighing and bagging again, these open, be discrete
Often there is the problem of powder is flown upward in process, deteriorate production environment, while bring material loss, mutually pollution and foreing impuritys
Thing, the quality of powder-product is set the risk reduced to be present.
Prior art has carried out certain improvement, such as Publication No. CN102172576A patent application in single devices
It is disclosed in screening link, using the device of Sealed sifting, the dust from flying of the link and further oxidation can be avoided；Such as
In packaging link, there is producer to use closed or protective atmosphere system, it is possible to reduce and avoid dust from revealing the problem of bringing.But
In the production whole flow process of powder, the automaticity of the powder delivery of links is also very low.After powder drying, enter
Before screening, powder allows for being transferred on screen(ing) machine exactly, at present industrial quarters usually using hopper transfer by the way of, do
Dry powder is discharged to hopper in drying machine, and powder hopper is then moved to screening seat in the plane with the instrument such as overhead traveling crane or ground ox
Put, fed using artificial or machine.There are a large amount of powder and unlimited air contact in the process, make environmental degradation, material
Material loss and cross pollution.Due in the entrance equipment of powder, take the volume in machine equipment cause amount of powder with exhaust and
Take out of, turn into airborne dust.During these problems are prevalent in powder transfer, the effective technological process of system there is no to solve
These problems.
