Description
Technical field
The utility model is related to a kind of Lavalle formula stomata atomizer.
Background technology
The production of nitrogen atomization ball aluminum powder is, by the small liquid grain of high temperature aluminum liquid mist chemical conversion, powder to be formed after cooling by atomizer
End.Original atomizer is tapering type stomata, is circumferentially uniformly distributed, and adjustment stomata outlet bore is constantly improved for many years
And stomata angle, main purpose is to improve nitrogen atomization ball aluminum powder D50：9 microns and following aluminium powder yield, improve product and add
Value.Although improving nitrogen atomization ball aluminum powder D50 by nebulizer technologies：9 microns and following aluminium powder yield improve a lot, but
Basically reach limiting value, then to improve difficulty very big.
Utility model content
The purpose of this utility model is to solve above-mentioned the problems of the prior art to be atomized there is provided a kind of Lavalle formula stomata
Device.
Lavalle formula stomata atomizer of the present utility model includes atomizer lower body, is socketed in atomization internal under atomizer
Device upper body, the air chamber formed between atomizer upper body and atomizer lower body, the connection air chamber set on atomizer lower body
Internal high temperature resistant nozzle in gas feed, embedded atomizer, on the circumference of the front end in atomizer upper body connected with air chamber
The angle at the equally distributed Lavalle formula stomata for being used to spray atomization gas, Lavalle formula stomata and center is 45 ° -65 °, excellent
Select 50 ° -60 °.
The major axis of Lavalle formula stomata Lavalle formula stomata corresponding with the circumference that the angle at center is atomizer upper body
Between the angle that is formed.
Lavalle formula stomata atomizer operation principle of the present utility model is as follows：The production of nitrogen atomization ball aluminum powder is in atomization
Air inlet chamber is entered in stage, gas feed of the atomization gas (pressure limit 4-8Mpa) on atomizer lower body, and atomization gas passes through mist
Change equally distributed Lavalle formula stomata on device upper body to accelerate to spray, in high temperature resistant spray nozzle front end formation vacuum.Because vacuum is taken out
Suction is acted on, and high temperature aluminium liquid is spread by high temperature resistant nozzle center passageway in exit, is crushed and is atomized into carefully by high speed atomisation gas
Small liquid grain, forms aluminium powder powder after cooling.Lavalle formula stomatal action is to accelerate atomization gas, muzzle velocity is reached Supersonic
Speed, the broken enhancing to aluminium liquid produces fine particle increase, thus further improve atomization ball aluminum powder D50 be 9 microns and with
Lower aluminium powder yield.
Brief description of the drawings
Fig. 1 show the structural representation of formula stomata atomizer in Lavalle of the present utility model.
Embodiment
As shown in figure 1, Lavalle formula stomata atomizer of the present utility model includes atomizer lower body 2, is socketed in atomizer
Down internal atomizer upper body 1, formed between atomizer upper body and atomizer lower body air chamber 7, set on atomizer lower body
Internal high temperature resistant nozzle 3 in the gas feed 4 of the connection air chamber put, embedded atomizer, connected with air chamber on atomizer
The equally distributed Lavalle formula stomata 5 for being used to spray atomization gas, Lavalle formula stomata and center on the circumference of the front end of body
Angle 6 be 45 ° -65 °, preferably 50 ° -60 °.
Nitrogen atomization ball aluminum powder is produced in atomization step, and atomization gas (pressure limit 4-8Mpa) is by atomizer lower body 2
On gas feed 4 enter air inlet chamber 7, atomization gas passes through equally distributed Lavalle formula stomata 5 on atomizer upper body 1 and accelerates spray
Go out, vacuum is formed in the front end of high temperature resistant nozzle 3.Due to vacuum suction effect, high temperature aluminium liquid passes through the central passage of high temperature resistant nozzle 3
In exit diffusion, crushed by high speed atomisation gas and be atomized into tiny liquid grain, aluminium powder powder is formed after cooling.Lavalle formula stomata
5 effects are to accelerate atomization gas, muzzle velocity is reached supersonic speed, the broken enhancing to aluminium liquid, produce fine particle increase,
So as to further improve atomization ball aluminum powder D50：9 microns and following aluminium powder yield.
Lavalle formula stomata atomizer of the present utility model is applied in nitrogen atomization ball aluminum powder production process, than original
The tapering type air passage atomizer of annular distance is estimated can to improve nitrogen atomization ball aluminum powder D50：9 microns and following aluminium powder yield about 5%.
Claims (2)
