Technical field
The utility model relates to liquid-crystalline glasses production field, specially a kind of melting systems for stabilized glass liquid level.
Background technique
In usual glass production, the fusing of glass is divided into five stages:
1. silicate formation stages, opaque sinter；
2. glass formation stages, non-uniform transparent glass (there are many striped, bubble presence)；
3. the clarification stage of glass first has visible bubble in bubble, finally disappears；
4. the homogenization stage (temperature is slightly below clarifying temp) of glass, it is uniform to finally reach no striped, component；
5. the cooling stage (temperature is gradually reduced by homogenization temperature) of glass metal, meets forming requirements.
Simultaneously in normal glass production, glass melting requires to accomplish four steady operations:
I.e. temperature is steady, furnace pressure is steady, foam line is steady, liquid level is steady.Wherein the control of liquid level is particularly important, and liquid level is such as
Fruit fluctuating range is excessive, overfrequency, to melting quality and shaping operation is all unfavorable.Liquid fluctuating is big, can accelerate resistance to liquid level position
The erosion of fiery material.The boundary line between glass metal and also unfused good glass metal melted in the case where normal production,
Foam line is generally lain in behind hot(test)-spot temperature." running material " refers to that the glass metal not being completely melt has crossed the position of hot spot.Liquid
Surface wave is dynamic be due to feeding quantity and load it is unbalanced caused by, while feeding quantity is unstable and can cause " run and expect " phenomenon.?
In the case that melting furnaces charging is few, melting furnaces fusing amount is insufficient, and foam line moves backward.In the case where melting furnaces charging is more, glass metal
Have little time to melt, foam line moves forward.Glass is required by control batch feeding amount, material heap shape, usual glass production
Liquid fluctuating control requires control in ± 0.2mm in ± 0.5mm when stringent.Fluctuation of metal line is mainly feeding quantity and discharging
Amount changes and causes.Metal level has to maintain to stablize, and the flowing of glass metal is to melten glass liquid, unfused cooperation
Expect that material heap position, distribution are critically important.

Specific embodiment
The following describes the utility model in further detail with reference to the accompanying drawings, it is described be the explanation to the utility model and
It is not to limit.
As shown in Figure 1, a kind of melting systems for stabilized glass liquid level, including batch charger 1, kiln and distributed AC servo system
The top of kiln is arranged in system, the outlet of batch charger 1.
Wherein, the temperature measuring equipment of the discharge port of batch charger 1 being provided centrally with for measuring material temperature, the temperature measuring equipment are heat
Galvanic couple 2, temperature measuring equipment is connect with dcs.It is provided with multiple electrodes group on the pool wall 4 of kiln, electrode group is embedded in
On pool wall 4, each electrode group is all connected with a heat-conducting plate, and heat-conducting plate is connect with dcs, dcs
The temperature of acquisition thermocouple feedback in real time, and according to the temperature of temperature adjusting electrode group, and then control glass metal in kiln
Temperature, the position on control material mountain avoid the occurrence of the phenomenon that material mountain is mobile, and material is run in appearance.
When feed temperature changes, dcs can timely export alarm, and operator is reminded to throw
Material happens exception, and operator is made to handle abnormal phenomenon in time.
Conductive plate is hollow structure, cooling pipe is arranged in conductive plate, cooling pipe is arranged in conductive plate with Z-type, cold
But the water inlet pipe 6 of pipeline is connect with waterworks, the return pipe of cooling water channel and return water reception device, and cooling water circulates pair
