Description
【Technical field】
The invention belongs to TFT glass manufacturing areas, more particularly to wall construction after a kind of drainage brick and TFT glass furnaces.
【Background technology】
In the manufacturing of TFT glass, glass melts the final mass of the quality influence product of quality, wherein TFT glass
Glass quality is required very high therefore very high to the requirement of furnace glass quality；Composition of raw material in glass production, fusing,
Rate of feeding, liquid fluctuating, refractory material corrodes in stove, the influences such as combustion state, furnace pressure, the material heap (foam line) of combustion rifle melt
There are many factor of quality, the variation of different process factor can caused by melt bad generation, therefore observe combustion state in kiln stove,
Feed intake situation, material mountain variation it is particularly significant.
We install high temperature industrial television by the wall after kiln thus, as shown in Figure 1A and 1B, to the kiln of normal operation
It is monitored in real time, it is ensured that glass melting is normally carried out；But high (about 1600 DEG C) are guarantee industrial electro due to glass furnace temperature
It runs well depending on long-time, we install water-cooled jacket using industrial television inner cavity, and industrial television pipette tips (high temperature camera) is made to exist
Kiln inside is monitored at lower temperature.Because cavity cooling water temperature is low, muzzle portion (camera) is made to generate condensed water,
In addition industrial television reasons in structure, industrial television cavity are stainless steel, are rushed by furnace high-temperature, inner flue gas of the stove, condensed water
Brush, surface erosion, volatilization dust, cavity eater, which are combined, in condensed water and stove to form object long-time of trickling and passes through slowly cavity
It flows into stove, falls into glass metal surface, (to ensure that industrial television is monitored tank furnace inside, industrial television in design installation
Vertical direction is closer to away from channel dog-hole) original trickling object is directly fallen into the glass metal below industrial television, and participates in glass
Convection current is melted, and the object that trickles falls into that glass metal middle-range dog-hole is closer, dog-hole is the glass metal separating device of glass furnace.Its
Effect is cooling and preferred glass metal for molding.When the relatively high glass metal of temperature in melting tank enters along dog-hole top
When work pool, temperature of glass liquid continuously decreases, and density gradually rises, and then portion temperature is relatively low in work pool, density compares
High glass metal sinks and returns to melting tank through dog-hole along bottom of pond, forms so-called glass-melt return-flow, and part trickling object passes through
Convection current enters platinum channel, is impacted to having melted glass quality, generates striped, and bubble etc. is bad, contains in the object that especially trickles
There is undissolved metallics, once flowing into platinum channel certainly will accelerate under high temperature according to metal power performances to platinum channel
Erosion；Reduce tank furnace channel service life.
【Invention content】
In order to solve the problems existing in the prior art, the present invention provides wall construction after a kind of drainage brick and TFT glass furnaces,
The industrial television trickling object of the present invention drains brick, and the effective trickling object that reduces participates in glass convection current around dog-hole, reduce into
Enter platinum channel, pollutes the glass metal melted.
In order to reach object above, the technical solution adopted by the present invention is：
A kind of drainage brick includes the cuboid brick body prepared using 33# corundum bricks, and the side of brick body is provided with drainage
Structure, the flow guiding structure are obliquely installed from brick body one end to the other end；The flow guiding structure is drainage tapered plane, drainage
Skewed slot or drainage inclined tube road.
The width of the drainage tapered plane is 30-50mm, and angle of inclination is 15-30 °.
Wall construction after a kind of TFT glass furnaces, including kiln back wall, industrial television, industrial television cavity brick, dog-hole
With drainage brick；The dog-hole is below the kiln back wall below metal level；The industrial television is placed in industrial television
In cavity brick, it is located at kiln back wall center position；The drainage brick is placed in immediately below industrial television cavity brick, is drained on brick
It is provided with flow guiding structure, the flow guiding structure is obliquely installed from drainage brick one end to the other end, for generating industrial television
Trickling object drain into the position far from dog-hole, the flow guiding structure is drainage tapered plane, drainage skewed slot or drainage inclined tube
Road.
The industrial television includes water-cooled jacket outside industrial television camera and industrial television camera.
The industrial television cavity brick opens hole, is open to be horn-like, 30-45 ° of the flare openings angle of inclination, work
Industry TV is arranged in the through-hole.
The width of the drainage tapered plane is 30-50mm, and angle of inclination is 15-30 °.
The drainage brick has multiple, and the kiln back wall below industrial television cavity brick is arranged in multiple drainage brick ladders
On.
The kiln back wall, industrial television cavity brick and drainage brick are all made of 33# corundum bricks.
Dog-hole 50-100mm below metal level；Industrial television is away from metal level 1000-1500mm；Industrial electro
Drainage brick bottom depending on underface is from dog-hole center 1000-1500mm.
Opposite and the prior art, the present invention have the following advantages：
The present invention makes corresponding drainage brick (refractory material with certain size, shape) and is tied with inclined drainage
Structure can both meet the use of industrial television function by the trickling object that will be flowed into stove far from dog-hole.It is simple in structure, design
Rationally, it is suitble to TFT glass manufacturing areas to use.
For the present invention according to situ industrial TV structure, the trickling object in stove will be flowed into far from flow liquid by making corresponding drainage brick
Hole had not only met the use of industrial television function, but also can reduce the glass convection current around its participation dog-hole, reduced logical into platinum
Road pollutes the glass metal melted.It is finally reached melting quality and meets technological requirement.After the TFT glass furnaces of installation drainage brick
Wall construction had both met industrial television and had normally used, ensure kiln normal operation, and can to flow into stove in condensation trickling object into
Row is intervened, other positions are drained to, and is reduced and is polluted to the glass metal melted around dog-hole, ensures melted glass
Liquid stream enters the glass metal of platinum channel, reaches melting quality and meets technological requirement.
