The present invention is exactly to overcome deficiency of the prior art, there is provided a kind of production method of high roundness glass microballoon and its
Device.
The present invention provides technical scheme below：
A kind of production method of high roundness glass microballoon, it is characterised in that comprise the steps：A, set gradually in cavity
Beading area and cooling zone；B, powered glass drop is imported into the cavity；C, the powered glass metal is made to drop in the cavity
Suspend and pass sequentially through the beading area and cooling zone under suspended state in the horizontal direction, and make the powered glass drop
Temperature is enhanced when by the beading area, by the cooling zone when cooled sizing, the glass for forming high roundness is micro-
Pearl；D, the high roundness glass microballoon is imported into product collecting device.
On the basis of above-mentioned technical proposal, there can also be technical scheme further below：
The powered glass drop is melting, and diameter is identical.
The powered glass drop is made to import the cavity by lateral airflow, the lateral airflow is high temperature hot gas stream.
Make the powered glass metal drop in the cavity by electric field force to suspend.
To drop in the powered glass metal by horizontal direction air-flow moved in the cavity in the horizontal direction and import product
Product collection device.
Implement a kind of device of the production method of high roundness glass microballoon, there is provided technical scheme below：
A kind of device of the production method of high roundness glass microballoon, it is characterised in that；It includes cavity, and cavity one end is provided with out
Mouth end, the cavity other end are connected with collection device；
A pair of electrodes plate is provided with cavity, heater is being provided with the cavity of the openend, near collection dress
The cavity put is provided with cooling device；
Be provided with lateral blower fan on the position that the openend side is spaced a distance, and the air outlet of the lateral blower fan with
Openend corresponding matching.
Invention advantage：
The production method of offer of the invention and its beneficial effect of device are：
1）By making glass suspending drops and improving the temperature of glass drop, reduce can glass drop viscosity, therefore on surface
The roundness of glass microballoon can be significantly improved under tension force effect；
2）Due to the repulsion effect between charged drop between electric charge, it is suppressed that the collision polymerization between drop, microballon is effectively reduced
Between adhesion, reduce percent defective, improve production efficiency；
3）By providing evenly sized melten glass drop, unify glass microballoon sphere diameter.

Fig. 3 is the A-A sectional views in Fig. 2；
Fig. 4 is the B-B sectional views in Fig. 2.
Specific embodiment：
A kind of production method of high roundness glass microballoon, it is characterised in that comprise the steps：
A, the length direction along cavity on the cavity of process units set gradually beading area and cooling zone；
B, by the process units of melten glass drop of the prior art, produce powered glass drop, then by lateral high
In the beading area that warm air-flow is blown into the powered glass drop in cavity 1, and the powered glass drop is melting, and
Diameter is identical；
C, made by electric field force the powered glass metal drop in the cavity suspend, so as to the effect of air-flow in the horizontal direction
Under, make powered glass metal drop under suspended state pass sequentially through the beading area and cooling zone in the horizontal direction, and make described powered
Glass metal is enhanced temperature, is shaped by being cooled during the cooling zone when dropping in by the beading area, form high roundness
Glass microballoon；
D, the high roundness glass microballoon is imported into product collecting device.
As described in Fig. 1-4, implement a kind of above-mentioned device of the production method of high roundness glass microballoon, it includes tubular cavity
Body 1,1 one end of cavity are openend 1a, and 1 other end of cavity is connected with collection device 6, and is also wrapped in described collection device 6
Air-introduced machine 7, and the inlet scoop of air-introduced machine 7 and 1 corresponding matching of cavity are included, the air-flow that the air-introduced machine 7 is produced will be molded in cavity
Glass microballoon suction collection device 6.
It is provided with lateral blower fan 5 on the position that the openend 1a sides are spaced a distance, and the lateral blower fan 5
Air outlet and openend 1a corresponding matchings.The described blowout of lateral blower fan 5 is high-temperature gas.When powered glass drop 22 is dripped
During between openend and lateral blower fan, powered glass drop 22 can be blown into cavity 1 by the high-temperature gas of the blowout of lateral blower fan 5
