Specific embodiment
As shown in Figure 1, the invention discloses a kind of grading devices of powder, comprising: classification tank body 1, dust removal and filtration
The inner cavity top of net 2, conical baffle 3, classification core bucket 4, closing in pipe 5, uniform flow orifice 6, the classification tank body 1 is provided with dedusting
Strainer 2, the center position of the dust removal and filtration net 2 offer powder inlet 20, in the inner cavity of the classification tank body 1 from up to
Inferior height is provided with multiple conical baffles 3, and the top of multiple conical baffles 3 offers central through hole 30, opened
If central through hole 30 in fixed plug classification core bucket 4 is installed, the top of the classification core bucket 4 is plugged in powder inlet 20
It is interior.
The classification core bucket 4 be located on the bucket wall between dust removal and filtration net 2 and the conical baffle 3 of top layer offer it is several
A sub-material mouth 1, the classification core bucket 4 offer several sub-material mouths two on the bucket wall between adjacent conical baffle 3
41, and the sub-material mouth 2 41 opened up on the bucket wall for the classification core bucket 4 being sequentially located between adjacent conical baffle 3 from top to bottom
Pore size be sequentially increased setting, the aperture of the sub-material mouth 21 opened up is greater than the aperture of sub-material mouth 1, the classification core
The base opening end of bucket 4 is affixed to be equipped with closing in pipe 5, and the base opening of the closing in pipe 5 is air inlet 50, is consolidated in the inner cavity of the closing in pipe 5
Dingan County is installed with uniform flow orifice 6, is provided with open corresponding with the inclination bottom end of conical baffle 3 on the side wall of the classification tank body 1
If dust outlet 10.
The dust outlet 10 connects the side pipe end of discharge nozzle 8, and the other end pipe end of the discharge nozzle 8 is connected to classification
Case, convenient for the particle discharge after the classification of powder size from top to bottom is classified tank body 1 by the discharge nozzle 8 of setting.
The protruding classification tank body 1 in the base opening end of the closing in pipe 5, and set the base opening end of the closing in pipe 5 is affixed
There is abutted flange 7, the abutted flange 7 of setting is convenient for abutting joint blast pipe.
Set mesh size is 1um on the dust removal and filtration net 2, so that the size of filter mesh is less than most starch
Last particle size avoids powder from drifting loss.
3 quantity of conical baffle of height setting is waited to be at least 3 from top to bottom in the inner cavity of the classification tank body 1, setting
Multiple conical baffles 3 application classification powder size, help to obtain finer particle size powders.
The present invention is implemented: in use, the powder inlet 20 opened up from dust removal and filtration net 2 to classification tank body
Powder particle is added in 1, powder particle is fallen into classification core bucket 4, and blasts wind out of closing in pipe 5 air inlet 50 simultaneously
Stream, powder particle is under distinguished and admirable wind-force rest effect, and bulky grain powder can swim in lower section, and small particle powder can be swum in
Side, the small particle powder of top layer's floating is between the conical baffle 3 and dust removal and filtration net 2 that sub-material mouth 1 enters top layer
It in cavity, and is fallen on conical baffle 3 in small particle powder self gravitation effect, and slides and opened up on extremely classification tank body 1
Dust outlet 10 in, and from discharge nozzle 8 slide to classification case internal classification storage；Because multiple conical baffles 3 are that equal height is arranged,
And be classified core bucket 4 and offer several sub-material mouths 2 41 on bucket wall between adjacent conical baffle 3, and from top to bottom according to
The pore size of the sub-material mouth 2 41 opened up on the bucket wall of the secondary classification core bucket 4 between adjacent conical baffle 3 is successively
Increase setting, so that powder particle is ascending, flowed out out of dust outlet 10 from top to bottom, realizes the behaviour of powder size classification
It deals with.Using the technical program, structure is simple, assemble it is easy for installation, by closing in pipe to classification core bucket in blast it is distinguished and admirable,
So that the powder particle being added, because of different sizes, formation layering setting from top to bottom, the particle powder being layered from top to bottom is distinguished
It is flowed out out of sub-material mouth one, sub-material mouth two, until conical baffle is fallen under particle powder self gravitation effect, so that from upper
It is flowed out out of dust outlet under and, realizes the operation processing of powder size classification, it is easy to operate, and classification efficiency is higher.
Finally, it should be noted that above embodiments are only to illustrate the present invention and not limit technology described in the invention
Scheme；Therefore, although this specification is referring to above-mentioned each embodiment, the present invention has been described in detail, this
Field it is to be appreciated by one skilled in the art that still can modify to the present invention or equivalent replacement；And all do not depart from this
The technical solution and its improvement of the spirit and scope of invention, should all cover within the scope of the claims of the present invention.
