Abstract
A kind of device for the homogenizing ability improving TFT substrate glass delivery system, includes the tubbiness teeter chamber being built into thermal insulation material, is vertically installed in the stirring rod in teeter chamber center.Thermal insulation material inner face structure at the top of the teeter chamber is the irregular hollow-core construction of up big and down small " E " shape or umbrella；In the thermal insulation material inner face at least provided with the heater that a material is platinum, tungsten, molybdenum one of which or its alloying metal；The electrical power of the heater is 1.0kW to 5.0kW.The technical solution of irregular thermal insulation material and heater is set on teeter chamber top since the utility model uses, pass through the temperature of heating stirring room upper layer cavity, the temperature difference for reducing glass melts can improve the homogenizing ability of glass melts stirring, promote base plate glass quality.The utility model has the characteristics that simple in structure, easy to implement, at low cost, glass melts stirring homogenizing ability is stronger.
Description
Technical field
The invention belongs to glass preparation fields, and in particular to a kind of homogenizing ability improving TFT substrate glass delivery system
Device.
Background technology
In TFT-LCD (thin film transistor liquid crystal display) base plate glass production process, stirring homogenizing glass melts are systems
The important process of standby high-quality base plate glass.
There are volatility and destructive oxide, such as platinum Pt, arsenic As and tin Sn in glass melts and teeter chamber, this
A little oxides will likely cause the critical defect of base plate glass.
Because the air on glass free surface than teeter chamber outside air themperature it is high, if air themperature is low in cavity
In the dew point of the volatile oxidn in teeter chamber's atmosphere, these oxides can be condensed and be fallen in glass melts simultaneously
Cause the inclusion defects in base plate glass product.The glass melts temperature gradient of stirring becomes larger simultaneously, and temperature difference increases, very
It is easy to keep the glass melts body of stirring uneven and generate split-phase and generate striped.Striped is in LCD sheet glass
One of major defect seriously affects product quality.
Currently, this field is solved using the heating power for improving platinum channel to improve the technical solution of temperature of glass liquid
State problem.But since the heating power for improving platinum channel makes platinum channel temperature excessively high, to reduce platinum channel
Service life causes cost to increase.
Invention content
In order to overcome the deficiencies of existing technologies, the purpose of this utility model, which is to provide one kind, can improve teeter chamber upper layer sky
Temperature degree reduces the device of the base plate glass melt homogenizing ability of glass melts temperature difference.
In order to achieve the above object, the technical solution of the utility model is such：
A kind of device for the homogenizing ability improving TFT substrate glass delivery system, includes the tubbiness being built into thermal insulation material
Teeter chamber is vertically installed in the stirring rod in teeter chamber center, and the thermal insulation material inner face at the top of the teeter chamber is irregular sky
Core structure, in the thermal insulation material inner face at least provided with a heater；
Further, the thermal insulation material inner face structure is up big and down small " E " shape or umbrella；
Further, the material of the heater is the metal of platinum, tungsten, molybdenum one of which or its alloy；
Finally, the electrical power of the heater is 1.0kW to 5.0kW.
The technical solution of irregular thermal insulation material and heater is set on teeter chamber top since the utility model uses,
By the temperature of heating stirring room upper layer cavity, the temperature difference of glass melts is reduced, the homogenizing of glass melts stirring can be improved
Ability promotes base plate glass quality.It is equal that there are the utility model simple in structure, easy to implement, at low cost, glass melts to stir
The stronger feature of change ability.
Description of the drawings
Fig. 1 is the diagrammatic cross-section of the utility model；
Fig. 2 is the sectional view of " E " type thermal insulation material；
Wherein：
1 is teeter chamber；2 be cavity；3 be stirring layer；4 be stirring rod；5 be thermal insulation material；6 be heater.
Specific implementation mode
The utility model is described further below in conjunction with the accompanying drawings.
Referring to Fig.1,2, a kind of device for the homogenizing ability improving TFT substrate glass delivery system, including with thermal insulation material 5
The tubbiness teeter chamber 1 being built into, is vertically installed in the stirring rod 4 in the center of teeter chamber 1, in the thermal insulation material 5 at 1 top of the teeter chamber
Face is irregular hollow-core construction, in 5 inner face of the thermal insulation material at least provided with a heater 6,5 inner face of the thermal insulation material
Structure such as show up big and down small " E " shape or umbrella from sectional view.
The material of the heater 6 is the metal of platinum, tungsten, molybdenum one of which or its alloy；The electrical power of the heater 6
For 1.0kW to 5.0kW.
Illustrate the course of work of the utility model below in conjunction with the accompanying drawings.
Referring to Fig.1,2, in base plate glass raw material melting process, in glass melts and teeter chamber 1 there are volatility and
Destructive oxide, such as platinum Pt, arsenic As and tin Sn.These oxides will likely cause the critical defect of base plate glass.It is logical
Often, the air themperature on glass melts stirring layer 3 is higher than the air themperature outside teeter chamber 1.If air themperature is low in cavity 2
In the dew point of the volatile oxidn in 1 atmosphere of teeter chamber, these oxides can be condensed and be fallen in glass melts
And cause inclusion defects in base plate glass product.The glass melts temperature gradient of stirring becomes larger simultaneously, and temperature difference increases,
It is easy to make the glass melts of stirring uneven.To reach the air themperature being kept stirring on layer 3 higher than the sky outside teeter chamber 1
Temperature degree, the utility model are for 5 inner face of irregular thermal insulation material, and stirring 3 above section of layer is provided with heater 6.Heat preservation
Material 5 not only realizes heat insulation function, in the middle part of protruding parts can also connect and deposit metal oxide, it is molten both to have improved glass in this way
The level of homogenization of liquid, and metal oxide can be prevented to fall directly into glass melts and cause product defects.
Not all or unique embodiment described above, those of ordinary skill in the art are right by reading this specification
Any equivalent transformation that the technical program is taken is that the claim of the utility model is covered.
