The preparation facilities working principle of gelled pill are as follows: general by calculating Bond number BOTo analyze in certain medium
Drop importance of the gravity relative to its surface tensionWherein Δ ρ and γ is respectively drop and the medium
Density contrast and drop surface tension in the medium, g is acceleration of gravity, and l is characteristic length, and the representative value of l is drop
Diameter.In the lesser situation of drop, BOValue it is smaller, the effect of the surface tension of drop account for it is leading, drop be spherical shape, because
This, needs to adjust the conditional parameter of preparation so that B during preparing larger particlesOValue is less than 1.It is limited in quasi-statics
In, the drop of the capillary lower end exit suspension of a vertical direction, in the gravity F being subject togIt is upward greater than what it was subject to
Capillary forceWhen, it can be separated with capillary lower end, wherein r is capillary inner diameter, and γ is the surface tension of liquid,
That is Tate rule, is expressed asOrWherein fHBIt is Huggins-Blang's calibration factor,
Also remain in the influence of the partially liq in capillary after dripping that reflects drop, d is liquid-drop diameter.Such as above-mentioned formula institute
Show, drop in air when, Δ ρ has a maximum value during droplet formation, and the liquid-drop diameter formed is small.In the present apparatus,
Such droplet is fallen to after being formed in oil type liquid such as decane so that its Δ ρ in the curing process reaches minimum value,
This process makes BOValue reduce, maintain the spherical shape of drop, select thinner capillary, it is straight drop can be further decreased
Diameter d still reduces capillary inner diameter r and makes the fluid pressure sharp fall at capillary outlet, to be difficult to maintain drop
High yield, the present apparatus applies another power to stimulate the drop at capillary outlet, disengages it from size when capillary
Smaller, i.e., by the way that capillary nozzle to be placed in downward air-flow, air-flow makes it to the pull effect of the drop shaped
Nozzle, the drag force F that air-flow applies can be more early detached fromD, work as satisfactionWhen, drop can go out with capillary
It is separated at mouthful, in general, the drag force of air-flow is expressed as FD=0.5CDAu2ρ, wherein u and ρ be respectively flow gas rate and
Density, CDIt is to pull coefficient, A is the section of obstacle, if dropCapillary outlet is constantly flowed in liquid
In the process, d is gradually increased, until meetingIt is separated at drop and capillary outlet, therefore, the liquid to drip
The size of drop can be calculated by above-mentioned formula.
Apparatus of the present invention use the nozzle with coaxial air stream to spray the drop of liquid gel, and use oil type liquid
The drop of gel is solidified, for can be individually distributed and size in the gelled pill of millimeter magnitude, installation cost is low, preparation
Method is simple, and the size of obtained gelled pill is more uniform.
