Description
Technical field
Glass metal clarification technique field is the utility model is related to, more particularly to a kind of raising melten glass liquid clear quality
Staged vacuum degassing apparatus.
Background technology
Traditional glass metal is prepared under atmospheric pressure state, and the whole clarifying process of glass metal is also in normal pressure shape
Completed under state, melten glass liquid obtained by melting sources at ambient pressure, stored under set point of temperature and maintain certain time, so as to profit
Make the bubble growth in melten glass with fining agent, float and remove bubble.For the larger glass of more difficult clarification viscosity also
There is the method for following vacuum deaerator：The whole de-aeration of melten glass liquid is completed under a reduced pressure, and deaeration area is maintained at certain
One negative pressure state fixed, melten glass liquid obtained by melting sources defined negative pressure and at a temperature of store and remain certain
Time, bubble in melten glass liquid make bubble contained in melten glass fast because the power excluded the reason for negative pressure becomes big
Speed becomes big, floated, and is then discharged from reduced atmosphere.But traditional vacuum deaerator is all to make the deaeration residing for melten glass liquid
Area's atmosphere maintains the target negative pressure of a certain fixation, and energy consumption is larger, and it is less desirable to run into high viscosity glass clarifying effect.
Utility model content
The purpose of this utility model is that energy consumption is higher in melten glass liquid clarifying process at this stage in order to solve, glass clarifying
The shortcomings of quality is undesirable, and bubble is more, and a kind of staged vacuum deaerator of the raising melten glass liquid clear quality proposed
Device.
To achieve these goals, the utility model employs following technical scheme：
A kind of staged vacuum degassing apparatus for improving melten glass liquid clear quality, including melting channel, it is characterised in that：
Melting channel connects vacuum deaerator groove by tedge, and one group of steam vent is provided with vacuum deaerator groove, in the outer of vacuum deaerator groove
Side is provided with shell, and in cage connection vavuum pump, the filling with insulation material between shell and melting channel, vacuum deaerator groove passes through decline
Pipe connects backflash.
On the basis of above-mentioned technical proposal, there can be technical scheme further below：
The vacuum deaerator groove is divided into No. I interconnected groove, No. II groove and No. III groove, and first row is provided with No. I groove
Gas port, second exhaust port is provided with No. II groove, the 3rd exhaust outlet is provided with No. III groove.
Pressure in No. I groove is P1, and the pressure in No. II groove is P2, and the pressure in No. III groove is P3,
Wherein P1>P2>P3, wherein P1<P0, P0 are atmospheric pressure.
P0-P1=50~300MPa, P1-P2=50~300MPa, P2-P3=50~300MPa.
Bleeding point is provided with the housing, and bleeding point connects the vavuum pump.
The utility model has the advantage of：The present apparatus to melten glass liquid by carrying out step wise reduction pressure so that molten
Melt glass metal after pressure reduction, bubble diameter of the bubble in melten glass liquid gradually increases the quick spilling of rising, and it is clear to reach deaeration
Clear effect, the method that the present apparatus fixes target negative pressure than traditional approach more can fully make bubble depart from melten glass liquid, improve
Melten glass liquid clear quality, substantially reduces energy consumption.
