Description
Technical field
The utility model is applicable to float glass process production sheet glass field, relates in particular to the heat-proof device in a kind of molten tin bath.
Background technology
Be accompanied by the increasingly mature and development of float glass process technology, adopt floating process to produce the main flow that sheet glass has become sheet glass.Adopt floating process can produce thickness 0.4mm～25mm sheet glass, and require the difference specification of quality high more for the more little glass of thickness itself because of its purposes, thin simultaneously glass is also just strict more to the requirement of operating mode in the molten tin bath groove.
Generally have outside the partition in the molten tin bath space in import and outlet; there is not other partition again to the molten tin bath interior volume; because of being divided into heat tracing zone and cooling zone substantially in the molten tin bath; the formation that the protection air-flow in two districts can have no to stop refluxes; because of two district's protection temperature degree differences can cause the cooling of heat tracing zone subregion; and the cooling zone can be heated once more, causes the disorder of temperature in the molten tin bath, thereby glass thin and thick difference and planeness are exerted an adverse impact.Just because of the disorder in molten tin bath temperature field, thereby cause the aggravation of tin liquor convection current, strengthened the probability of tin liquor oxidation, the one, cause the waste of tin liquor, the 2nd, impurity such as tin ash can produce considerable influence to glass sheet quality.
Summary of the invention
For molten tin bath heating zone and cooling zone are separated fully; stop the air-flow of two districts protection moving; effectively improve molten tin bath spatial internal pressure; reduce the oxidation of tin liquor; improve the quality of sheet glass, the technical scheme of employing is: the heat-proof device in a kind of molten tin bath is applicable in the molten tin bath of float glass process formed glass manufacturing sheet glass; include in the structure: be arranged on the heat insulation wallboard in the molten tin bath, heat insulation wallboard is positioned on the pulley in the molten tin bath supporting steel frame by supporting suspension type regulating mechanism.
The beneficial effects of the utility model are: the molten tin bath operating mode of using heat insulation wallboard is comparatively stable, vertical temperature gradient and horizontal temperature gradient are reasonable, particularly temperature is scientific and reasonable in the heat tracing zone, provide good environment for adjusting the glass planeness, the space internal pressure increases, and reduces tin liquor oxidation probability; The cooling zone cooling performance is more obvious, has reduced the glass shrinking percentage significantly, and temperature in the space, pressure regime are reasonable, make glass quality have significantly and promote, and are specially adapted to produce the molten tin bath of ultra-thin glass.
The utility model is simple in structure, can regulate, and the tolerance range height, easy to control.

Among the figure, 1 is heat insulation wallboard, and 2 is lifting rope, and 3 is balancing weight, and 4 is pulley, and 5 is the molten tin bath supporting steel frame, and 1-1 is a pylon, and 1-2 is a temperature sensor, and 6 is the molten tin bath top cover, and 7 is the tin liquor face, and 8 is molten tin bath.
Specific implementation process
Referring to accompanying drawing, the technical solution adopted in the utility model is: the heat-proof device in a kind of molten tin bath, be applicable in the molten tin bath of float glass process formed glass manufacturing sheet glass, include in the structure: be arranged on the heat insulation wallboard 1 in the molten tin bath, heat insulation wallboard 1 is positioned on the pulley 4 in the molten tin bath supporting steel frame 5 by supporting suspension type regulating mechanism.
In the technical solution of the utility model, hanging in the regulating mechanism of described heat insulation wallboard 1 includes: pylon 1-1, be fixed on the balancing weight 3 on the pylon 1-1, balancing weight 3 and heat insulation wallboard 1 form suspension type and regulate Weighting system by being positioned at pulley 4 on the pylon 1-1 and the lifting rope in the pulley groove.
In the technical solution of the utility model, the position of hanging of described heat insulation wallboard 1 is provided with according to the temperature requirement of molten tin bath 8.
In the technical solution of the utility model, the quantity of described heat insulation wallboard 1 is provided with according to the width of molten tin bath 8, and number is 2-6.
In the technical solution of the utility model, the material of described heat insulation wallboard 1 is: sillimanite.
In the technical solution of the utility model, described heat insulation wallboard 1 is provided with temperature sensor 1-2.
Referring to accompanying drawing 1, heat insulation wallboard 1 is installed on molten tin bath 8 specific positions, and molten tin bath 8 heat tracing zones and cooling zone are obviously distinguished, and the protection air-flow of having blocked two districts is moving, has improved two district's space pressure.Heat insulation wallboard 1 adopts refractory materials, can effectively reduce of the erosion of molten tin bath 8 interior hot environments to heat insulation wallboard 1, simultaneously processing will be polished in its surface, avoids impurity such as tin steam attached on the heat insulation wallboard 1, and the back drippage that accumulates over a long period causes the influence to glass quality.Hanging in molten tin bath top cover 6 of the heat insulation wallboard 1 firm safety of the pylon of heat insulation wallboard 1-1, setting device can be adjusted the height of hanging of heat insulation wallboard 1 flexibly simultaneously, according to hanging the setting of highly carrying out counterweight, quantity to balancing weight 3 is regulated, and can adjust the slight fluctuations of molten tin bath 8 operating modes by the adjusting of height.Referring to accompanying drawing 3, heat insulation wallboard 1 is provided with temperature sensor 1-2, can do the temperature of the tin liquor in the molten tin bath 8 and implement monitoring.
Heat insulation wallboard 1 is to hang on big cover steel structure framework by bolt, and both sides combine by pulley 4 supporting steel frames 5, to increase its steadiness.Heat insulation wallboard 1 can move down by pylon 1-1, adjusts the partition effect of heat insulation wallboard 1 by its aperture.
Referring to accompanying drawing 2, can be effectively be divided into two in the molten tin bath 8 in will molten tin bath top cover 6 by heat insulation wallboard 1, form the temperature field of a closed stablity, can realize the edge machine zone minimum lateral temperature difference at molten tin bath 8 front ends, thereby reduce the convection current of tin liquor, significantly reduce the glass surface percent ripple; Simultaneously stable because of molten tin bath 8 front end temperature fields keeps molten tin bath 8 both sides temperature, can realize the effective control to sheet thickness, particularly for ultra-thin glass, can be fast the thickness of glass difference is controlled in 50 microns.Molten tin bath 8 back segment major functions are that molded good sheet glass cools off, and owing to stopping of heat insulation wallboard 1, molten tin bath 8 front end pyritous protection gas can not enter back segment and cause molten tin bath 8 back segment transverse temperature inequalities that glass annealing is impacted.
Control of the present utility model has accuracy and validity, is specially adapted to produce the molten tin bath 8 of ultra-thin glass.After adopting apparatus of the present invention, can realize effectively that molten tin bath 8 changes the stable of molten tin bath 8 operating modes in the recovery of operating mode behind the plate and the daily production, this is particularly important for producing ultra-thin glass.
After adopting the utility model device,, therefore need not open or open less 8 electrically heated of part molten tin bath because molten tin bath 8 front ends have been carried out cutting off effectively insulation; Reduce the usage quantity of water coolant bag simultaneously for molten tin bath 8 back segments, help reducing molten tin bath 8 transverse temperature differences,, help saving energy and reduce the cost, increased the market competitiveness of glassy product so reduced glass cost effectively.
