Technical field
The utility model belongs to glassmaking art, more particularly to a kind of overflow brick front apron flow controlling device.
Background technology
The flat-panel monitors such as general TFT-LCD (TFT thin film transistor monitor), PDP (PDP) manufacture neck
Based on base plate glass used in domain is manufactured in the way of overflow down draw, the glass that will have been melted in molding procedure by glass furnace
Glass liquid is supplied to melt overflow pull-down forming device to manufacture.The thickness of base plate glass must be controlled in the range of ± 0.015 ㎜,
Any technological fluctuation or overflow mechanism design error can all be adversely affected to the quality of glass substrate.
It is one of technology of glass substrate forming optimal quality using the overflow downdraw of wedge body overflow brick, with other glass
Glass manufacture of substrates is compared, and the glass baseplate surface of melt overflow glass tube down-drawing manufacture has excellent flatness and smoothness,
It is preferred glass substrate manufacturing technology.The key factor for implementing fusion method is the quality of former end (proximally and distally)
Flow is controlled, and distally refers to one end away from feed, and near-end refers to close to one end of feed.End glass metal too small flowing and drawing
It can make that the property of glass substrate is unstable, causes performance issue and causes product yield to decline.
Mass flow to the melten glass of overflow brick both ends (proximally and distally) predetermined length scope overflow is controlled
System, in order to avoid the transient change that heat is distributed in the distribution of glass quality, glass quality and glass substance, i.e. use overflow downdraw
Size and the stable glass substrate of performance are manufactured, the flow of former end needs special control.
Utopian overflow analytical design method (such as Dockerty flow formulas) can not ensure the reality for obtaining satisfaction completely
Flushing effect, it is necessary to take effective means to optimize amendment, such as physical analogy and analogue simulation to design.Nonetheless,
It cannot be guaranteed that overflow brick end particularly near-end is rapidly reached certain thickness or mass flow, to be taken in the near-end of overflow brick
The stability of effective measures guarantee manufacture.
In view of problem above, the utility model provides a kind of flow controlling device, near-end can be ensured by the device
It is rapidly reached the flow or thickness of needs.

Body shape structure, and the upper surface of shaping overflow brick is slope, slope offers rectangle overflow launder, overflow launder both sides along line of slope
Wall is spillwag chute, and the top of spillwag chute is downflow weir；
Front apron includes front apron main body and front apron training wall；Front apron main body is arranged on slope top, and with two
Spillwag chute is in contact；Front apron training wall is arranged on the upper surface of front apron main body；Front apron training wall is c-type, c-type concave surface court
To overflow launder.
Further, the slope lower end of shaping overflow brick is provided with rear baffle.
Further, isopipe root is curved surface.
Further, overflow face thickness is E, and front apron training wall opening size is D, and front apron training wall lateral separation is
B, front apron training wall bottom size is C, and distance of the front apron water conservancy diversion wall opening away from overflow brick is A；Spillwag chute thickness E≤
80mm, front apron water conservancy diversion wall opening is away from overflow brick inlet apart from A≤120mm；0≤D of front apron training wall opening size≤
E；0≤C of front apron training wall bottom size≤E；0≤B of front apron water conservancy diversion arm lateral separation≤2A/3.
Further, it is preceding when the material of plate and rear baffle is platinum.
Compared with prior art, the utility model has following technique effect：
The utility model in the front end of overflow brick by setting front apron, to the predetermined length scope overflow of overflow brick end
The mass flow of melten glass is controlled, in order to avoid the wink that heat is distributed in the distribution of glass quality, glass quality and glass substance
Shi Bianhua, can limit the excess flow and the thickness rate of climb of overflow brick near-end, so as to during glass is manufactured, improve
The stability of glass substrate, increases the yields of product.
