Abstract
The utility model relates to a control device for temperature distribution during a forming process for producing a piece of plate glass according to an overflow down-drawing method and especially relates to a device for controlling a forming temperature field of the plate glass. The device is characterized by comprising two sets of separating plates (6, 7), wherein each set of separating plates is composed of two separating plates and each of the separating plates is connected with a rotating shaft and is rotated around the rotating shaft. The utility model provides the device for controlling the forming technical temperature during the process of producing the plate glass. The device is formed by coating a metallic material which can resist temperature above 900 DEG C on a heat-insulating material; the device is used for dividing the process of the plate glass from the overflow tank outflow to the forming and annealing treatment into different temperature control regions; and an independent temperature regulating and controlling device (such as a heater, an air cooling pipe and a water cooling pipe) is arranged in each of the regions. The temperature distribution of the independent regions divided by the separating plates can more optimally reach a target temperature for forming the glass, and after production is stabilized, the heat-preserving effect of the temperature field of the plate glass is better.
Description
Technical field
The utility model relates to overflow downdraw and produces the temperature distribution gear of sheet glass in moulding process, especially a kind of device of controlling the formed from plate glass temperature field.
Background technology
Overflow downdraw is a kind of technology that glass work is produced sheet glass, in U.S. Pat 3,338; In 696 and US3,682,609 overflow downdraw has been described; System comprises inlet end, and this inlet end is supplied with the overflow body that refractory materials is processed with the glass of fusing, overflows the fluidic overflow groove after the melten glass steady-state operation; The glass of fusing overflows groove top from the overflow groove both sides; Flow along overflow body two sides, the melten glass of final both sides is intersected in the fluidic root that overflows, and fuses into monolithic glass jointly at this place.Get into the formed from plate glass stage then, this stage sheet glass is drawn to the thickness of required sheet glass by drawing device, and this drawing device is controlled its thickness through the speed that is pulled away from sheet glass from overflow body root.In any stage of overflow to moulding, the outside surface of sheet glass is any medium beyond the ingress of air not, therefore can obtain the high sheet glass of surface property.
The utility model content
The purpose of the utility model provides a kind of device of controlling the formed from plate glass temperature field, can make temperature distribution be more suitable for the target temperature of glass ware forming, and it is also better to produce its heat insulation effect of stable back.
A kind of device of controlling the formed from plate glass temperature field, its special feature are, comprise two groups of dividing plates, and wherein each group dividing plate is formed by 2 dividing plates, thereby each dividing plate all is connected with a rotation axis and can rotates around this rotation axis.
Wherein each rotation axis all is connected with the end of a support, and the end of this support has the deep-slotted chip breaker that cooperates with rotation axis.
Its median septum is an asbestos plate.
Its median septum inside is filled with insulating cotton.
The utility model provides a kind of temperature controlled device of producing in the sheet glass process of moulding process; This device is to coat lagging material by the metallic substance of heatproof more than 900 ℃ to process; Be used for that sheet glass is flowed out to moulding annealed process from overflow groove and be divided into the different temperature control interval, all there is independently temperature control device (like well heater, forced air cooled tube, water cooling tube) in each interval.Via the separate portions that dividing plate is cut apart, the target temperature that reaches glass ware forming that its temperature distribution can more be optimized, and after production was stable, the heat insulation effect in its temperature field was also more excellent.
Description of drawings
Fig. 1 is the user mode synoptic diagram of the utility model.
Embodiment
As shown in Figure 1, a kind of device of controlling the formed from plate glass temperature field comprises two groups of dividing plates 6,7; Wherein each group dividing plate is formed by 2 dividing plates, thereby each dividing plate all is connected with a rotation axis and can rotates around this rotation axis, and wherein each rotation axis all is connected with the end of a support; The end of this support has the deep-slotted chip breaker that cooperates with rotation axis; Dividing plate is that for example asbestos plate is processed, and is filled with insulating cotton in dividing plate inside by high temperature resistant high material more than 900 ℃.
The formative stage of sheet glass; Be thickness, the stress of adjustment glassy product, the critical process of warpage, to the temperature adjusting of a certain specification of product, the global temperature that will bring changes; Cause the temperature field disturbance of the overall situation, this disturbance will make other specifications of product receive uncontrollable fluctuation.Adopt the utility model device that whole formative stage is divided into some relatively independent temperature ranges; Because the dividing plate inner packet is covered with lagging material; Interval mutual thermal perturbation meeting reduces, and therefore can significantly promote the stability of production quality control in the products production.
Development along with the TFT technology needs continuing to increase of sheet glass size, and aforementioned barriers length also constantly extends.Under the hot environment in glass ware forming stage, even adopt high temperature material, material receives influence of high-temperature creep; The very fast sagging distortion in back of dividing plate causes its thermal insulation deleterious, and the device of the utility model comprises support; Has the arc groove face that cooperates processing with the dividing plate rotating shaft in the end of support; Be used for supporting clapboard, thereby greatly reduce the speed of dividing plate creep, promoted the work-ing life at least 50% of dividing plate.
As shown in Figure 1; Glass metal 5 flows down from the root of overflow body 4; Two groups of dividing plates 6,7 with the glass ware forming zone vertically (interval) from the temperature field of leaving overflow body 4 to glass ware forming annealed zone be divided into that retort furnace is interval 1, between the shaping area of top 2 and the bottom shaping area between 3; Stay the slit that is flowed down by sheet glass in the middle of two dividing plates, one-sided dividing plate and sheet glass are apart from keeping 10mm～30mm; Stay the slit that is flowed down by sheet glass in the middle of two dividing plates, one-sided dividing plate and sheet glass are apart from keeping 10mm～30mm.The dividing plate moving axis that can rotate rotates; Its one-sided open angle is 0 °～+ 90 °; Wherein interval 1 thermograde of retort furnace is 1250 ℃～1100 ℃, and 2 thermogrades are 1100 ℃～900 ℃ between the shaping area of top, and 3 thermogrades are 900 ℃～750 ℃ between the shaping area of bottom.Dividing plate supports at the end face of bracket end in addition, and support does not limit the rotational freedom of dividing plate, and the envrionment temperature of support and dividing plate work is 700 ℃～1000 ℃.
