Description
Technical field
The present invention relates to glass production field, a kind of furnace hearth structure for reinforcing fiber glass melter is specifically referred to.
Background technology
Float glass is widely used, and is divided into coloured glass, float glass process silver mirror, float glass/automotive windshield level, float glass/all kinds of deep processing levels, float glass/scanner level, float glass/plated film level, float glass/mirror level processed.Wherein ultra-white float glass tool has been widely used and wide market prospects, is mainly used in top-grade building, high-grade glass processing and solar energy photoelectric curtain wall field and high-grade glass furniture, ornamental glass, imitative crystal product, fitting glass, precise electronic industry, extraordinary building etc..The forming process of float glass is to be passed through protective gas（N2 and H2）Molten tin bath in complete, melten glass is continuously flowed into from tank furnace and swum on relatively denser tin liquor surface, in the presence of gravity and surface tension, glass metal spreads out on tin liquor face, shakeouts, it is smooth to form upper and lower surface, hardening, drawn transition roller table after cooling；Glass tape, is pulled out molten tin bath and enters annealing kiln by the roller turn of roller tables, and annealed, cutting just obtains float glass product.
In various glass productions, in order to increase tank block service life and ensure glass product quality, pool wall cooling wind must be used, but pool wall cooling wind is blown into lower gap and can cause the defect increase of the bubble of glass, calculus, particularly cover-plate glass is higher to the requirement of glass metal cleannes, just should carry out certain improvement to glass furnace pool wall tuyere.In the prior art be traditional tuyere, cooling wind energy be directly blown into lower gap hence into kiln, have a strong impact on glass quality.
The content of the invention
It is an object of the invention to provide a kind of furnace hearth structure for reinforcing fiber glass melter, pool wall wind is prevented directly to be blown into lower gap and debris etc. is brought into and polluted in kiln glass metal, to solve the problems, such as to influence glass quality in order to cool down tank block.
The purpose of the present invention is achieved through the following technical solutions：
A kind of furnace hearth structure for reinforcing fiber glass melter, including the airduct and pool wall tuyere that are connected with compressed air source, the pool wall tuyere is connected by bending section with airduct, the pool wall tuyere is made up of interconnection tuyere top and tuyere bottom, the tuyere top is trapezoidal plate, trapezoidal plate base more long is connected with tank block outer wall, and the shorter base of the trapezoidal plate is connected with bending section, the length of the length more than tuyere bottom on tuyere top.To ensure tank block life-span and glass production quality, need ceaselessly to carry out cooling radiating to glass furnace tank block in Improving Glass Manufacturing Processes, and the mode for radiating is generally using water-cooled air cooling or water-cooled and air cooling composite radiating, water spent by water-cooling is excessive, most enterprises are inclined to and by the way of air cooling or air cooling and water-cooled composite radiating, but when air cooling radiates, airduct is directly directed at the bearing plate for breastwall of glass furnace and lower gap, to exchange cooling effectiveness higher for, minority cooling wind or impurity can be blown into lower gap and can cause the bubble of glass by the air of a large amount of circulations, the defect of calculus increases；During present invention work, cooling air is passed through from compressed air source to airduct, the cooling gas of quick flowing directly changes flow direction by the reflection of bending section, last pool wall tuyere blows to tank block to carry out refrigerating work procedure, tuyere top is directly connected to tank block, and unconventional setting means are directly by the bearing plate for breastwall of pool wall tuyere alignment glass furnace and lower gap, and then so that the cooling wind of direct current is entered into inside glass furnace in will not blowing to lower gap, prevent to cool down wind and bring in kiln debris etc. into pollute glass metal so as to improve product quality, length of the length on tuyere top more than tuyere bottom, the cooling wind of direct current is flowed directly out by the tuyere bottom of groove type and processed with the cooling down carried out to tank block, the cooling effect caused by after tuyere top is connected with tank block appearance is avoided to decline.
Multiple spiral grooves are additionally provided with the tuyere bottom.The multiple spiral grooves set in groove may be such that mixed gas form turbulent flow with the cooling gas that air inlet is flowed into groove, and then cause that the flowing velocity of cooling gas is accelerated, and cooling effectiveness of the cooling gas to tank block is improved within the unit interval.
The tuyere bottom is the arc groove or V-shaped groove that external diameter successively decreases along tank block direction.The tuyere bottom of arc groove or V-shaped groove ensure that the quick flowing of cooling gas, the external diameter of tuyere bottom successively decreases along tank block direction, the unit volume for cooling down gas is enabled to reduce suddenly, the air velocity sprayed from tuyere bottom is improved suddenly, and cooling effect of the cooling gas to tank block is enhanced indirectly.
The present invention compared with prior art, has the following advantages and advantages：
1, a kind of furnace hearth structure for reinforcing fiber glass melter of the invention, tuyere top is directly connected to tank block, and unconventional setting means are directly by the bearing plate for breastwall of pool wall tuyere alignment glass furnace and lower gap, and then so that the cooling wind of direct current is entered into inside glass furnace in will not blowing to lower gap, prevent to cool down wind and bring in kiln debris etc. into pollute glass metal so as to improve product quality, length of the length on tuyere top more than tuyere bottom, the cooling wind of direct current is flowed directly out by the tuyere bottom of groove type and processed with the cooling down carried out to tank block, the cooling effect caused by after tuyere top is connected with tank block appearance is avoided to decline；
2nd, a kind of furnace hearth structure for reinforcing fiber glass melter of the invention, the multiple spiral grooves set in groove may be such that mixed gas form turbulent flow with the cooling gas that air inlet is flowed into groove, and then cause that the flowing velocity of cooling gas is accelerated, cooling effectiveness of the cooling gas to tank block is improved within the unit interval；
3rd, a kind of furnace hearth structure for reinforcing fiber glass melter of the invention, the external diameter of mouth bottom successively decreases along tank block direction, enable to the unit volume for cooling down gas to reduce suddenly, the air velocity sprayed from tuyere bottom is improved suddenly, cooling effect of the cooling gas to tank block is enhanced indirectly.
