Abstract
A kind of slag case lower box nitrogen gas seal equipment, it is characterized in that: be provided with nitrogen bag at the sidewall of slag case lower box, nitrogen bag is communicated with the nitrogen inlet through slag case lower box sidewall; Multiple uniform venting hole is provided with in nitrogen bag bottom.Described nitrogen bag two ends are communicated with nitrogen inlet.Described nitrogen bag bottom is in tilted layout inside slag case lower box, and venting hole is corresponding inclination also.A kind of slag case lower box nitrogen gas seal equipment that the utility model provides, wraps in slag case lower box internal surface by the nitrogen arranged and forms nitrogen air curtain, can not affect the operating mode of slag case, ensure that the operation of glass ribbon safety in slag case.Because adjusting easily, operating steadily, effectively can reduce the surface imperfection of ultra-thin glass, improve the quality of production.
Description
Technical field
The utility model relates to technical field prepared by ultra-thin glass, especially a kind of slag case lower box nitrogen gas seal equipment.
Background technology
At present, the slag case lower box that thin float glass production line uses is without nitrogen gas seal equipment, and the sulfur dioxide gas that outside air, slag case use very easily enters from molten tin bath tail end; Oxygen in air and tin liquor react the loss that the oxide compound generating tin causes tin; Sulfurous gas enters molten tin bath and tin liquor and reacts and produce the sulfide of tin; The sulfide of tin and oxide compound not only pollute tin liquor but also the defects such as tin sticky, trising from tempering float glass, adhesive, light distortion shape can be caused to have had a strong impact on the quality problems of glass surface.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of slag case lower box nitrogen gas seal equipment, stable air curtain is formed by passing into nitrogen, ensure the stopping property of molten tin bath tail end, thus a series of glass surface quality problems effectively avoiding ambient atmos to enter causing, maintain the stable of molten tin bath operating mode.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of slag case lower box nitrogen gas seal equipment, is provided with nitrogen bag at the sidewall of slag case lower box, and nitrogen bag is communicated with the nitrogen inlet through slag case lower box sidewall;
Multiple uniform venting hole is provided with in nitrogen bag bottom.
Described nitrogen bag two ends are communicated with nitrogen inlet.
Described nitrogen bag bottom is in tilted layout inside slag case lower box, and venting hole is corresponding inclination also.
Above slag case, be also provided with multiple extraction hood, extraction hood is by metal hose and waste air pipeline communication, and waste air pipeline is provided with aerofoil fan.
A kind of slag case lower box nitrogen gas seal equipment that the utility model provides, wrap in slag case lower box internal surface by the nitrogen arranged and form nitrogen air curtain, the air curtain formed is even and stable, can not affect the operating mode of slag case, ensure that the operation of glass ribbon safety in slag case.Because adjusting easily, operating steadily, effectively can reduce the surface imperfection of ultra-thin glass, improve the quality of production.The gas barrier arranged, by waste gas carrying-off while sealing, can not impact the operation of slag case and molten tin bath, and decreases the various problems because waste gas produces; The surface imperfection of effective reduction ultra-thin glass, the health of human body of protection employee.The utility model simplicity of design is reasonable, and low cost of manufacture, and the nitrogen that can utilize secondary circulation, reach energy-conservation object.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Fig. 1 is one-piece construction schematic diagram of the present utility model.
Fig. 2 is the A direction view of Fig. 1.
In figure: nitrogen bag 1, nitrogen inlet 2, slag case lower box 3, venting hole 4, extraction hood 5, metal hose 6, waste air pipeline 7, aerofoil fan 8.
Embodiment
As in Fig. 1,2, a kind of slag case lower box nitrogen gas seal equipment, is provided with nitrogen bag 1 at the sidewall of slag case lower box 3, and nitrogen bag 1 is communicated with the nitrogen inlet 2 through slag case lower box 3 sidewall;
Multiple uniform venting hole 4 is provided with in nitrogen bag 1 bottom.The pure nitrogen gas passed into is exchanged by tin bath outlet lip tile cold gas cycling hot to enter nitrogen bag 1, can not impact through preheating to the temperature of slag case lower box.After preheating in nitrogen bag 1, nitrogen is from for intensive and uniform venting hole 4 is allotted, and guarantees the stability of air curtain.Structure thus, while stop ambient atmos enters, self and tin liquor do not react, and avoid the pollution of tin liquor.
Preferably, described nitrogen bag 1 two ends are communicated with nitrogen inlet 2.Nitrogen bag 1 two ends pass into the homogeneity that nitrogen ensures gas intake simultaneously.
Preferred as in Fig. 1, described nitrogen bag 1 bottom is in tilted layout inside slag case lower box 3, and venting hole 4 is corresponding inclination also.Structure thus, air curtain turnover is level and smooth, reduces the probability that turbulent flow is formed.
Preferred as in Fig. 1, above slag case, be also provided with multiple extraction hood 5, extraction hood 5 is communicated with waste air pipeline 7 by metal hose 6, and waste air pipeline 7 is provided with aerofoil fan 8.Setting property pipe 6 can avoid the vibration effect of aerofoil fan 8 to equipment.Although have employed nitrogen-sealed in the utility model, in order to improve lower glass surface quality on floatation glass production line, use a large amount of sulfur dioxide gas at slag lower box part, and the consumption of thin float glass is especially many.But sulfurous gas uses excessive meeting to enter molten tin bath and tin liquor reacts the sulfide generating tin, tin is caused to pollute night; Destroy molten tin bath atmosphere; Corrode the hardware of molten tin bath and slag case; Graphite oxide; Sulfurous gas or the excessive health that can affect employee of a kind of toxic gas suction.Only be not enough to solve the excessive problem causing interference of waste gas by nitrogen-sealed, by the gas barrier preferably arranged, independent of slag case body, independent installation and operation, can not impact the operation of slag case and molten tin bath, and then decrease the various problems because waste gas produces; The surface imperfection of effective reduction ultra-thin glass, the health of human body of protection employee.
