Description
Technical field
The present invention relates to glass field shaping technique, a kind of space-separating device of molten tin bath is specifically referred to.
Background technology
The glass metal melted in tank furnace, at high temperature molten tin bath is flowed into along runner, because the density of glass only has 1/3 of tin liquor or so, thus swim on tin liquor face, and uniform glass tape is formed in its flow process, glass is lifted when certain temperature is cooled to by transition roller table, molten tin bath is left under the effect of rollgang tractive force, into annealing kiln annealing.
Molten tin bath is one, and by refractory material and steel part closed slot type receptacles, the inside is the tin liquor of melting, and glass is swum on tin liquor face, and because tin liquor is easily aoxidized, molten tin bath requirement closing is intact.Sealing gland is taken in molten tin bath inducer, check apron is taken in tin bath outlet section, prevent air from entering molten tin bath；All-sealed structure is taken at molten tin bath top, prevents air from entering molten tin bath；Protective gas is passed through inside molten tin bath, protective gas is usually that reducibility gas prevent tin liquor from aoxidizing.
Top sealing structure is usually all equal bottom, is 1.5m or so apart from tin liquid level, and the space in such structure molten tin bath communicates.Because the glass in molten tin bath is a linear change by high temperature to low temperature, the temperature of the protection gas in space be also it is linear from high to low, the space protection gas for communicating will be disturbed mutually, and one is that the quickening for causing heat is lost, and is unfavorable for energy-conservation；Two is that high/low temperature gas phase mutually to be disturbed falls under the impurity that can be caused in space and cause shortcoming to glass on glass.Particularly to glass such as glass quality requirement extra high PDP, TFT, LCD, the space for communicating can not meet high standards.
The content of the invention
It is convenient in float glass it is an object of the invention to provide a kind of molten tin bath improved structure for fibrous glass melting furnaces, the debris floated in cell body space are quickly collected, debris are preferably minimized to the influence that forming of glass quality is caused.
The purpose of the present invention is achieved through the following technical solutions：
A kind of molten tin bath improved structure for fibrous glass melting furnaces, including cell body and the top cover being covered in directly over cell body, one is at least provided with below the top cover space between top cover and cell body is separated into two or more demarcation strips, collection structure is provided with the both sides of demarcation strip.During present invention work, first tin liquor is avoided to be oxidized to restitutive protection's gas is passed through in cell body, glass metal have at import flow into cell body in, because the glass in cell body is a linear change by high temperature to low temperature, the temperature of the protection gas in space be also it is linear from high to low, the space protection gas for communicating will be disturbed mutually, the quickening of heat is caused to lose, energy consumption is caused to be aggravated, the demarcation strip equi-spaced apart being made up of refractory material is set, cell body upper space is separated into multiple equal-sized separate spaces, ensure the temperature subregion in cell body space and the control of protective gas composition in different temperatures region, so that glass is when with self-temperature linear decline, avoid the temperature of the heat radiation influence one's respective area in previous region, reduce influence of the temperature change to glass；The demarcation strip for being vertically installed in cell body avoids the mutual disturbance of the protective gas for communicating space, reduces the loss of heat, also saves substantial amounts of energy；Floating refuse collecting in the separate space that the collection structure being arranged on the both sides of demarcation strip bottom can be constituted two neighboring demarcation strip, avoiding debris from being scattered on glass influences its quality, improve the raw sheet Forming Quality of glass, collection structure of the present invention is made up of refractory material, and be mutually perpendicular to demarcation strip, directly the floating debris in the compartment can be collected, square groove is provided with collection structure, U-lag, dovetail groove or deep-slotted chip breaker etc. can pile up the collecting tank of debris, molten tin bath concentrates cleaning to pile up again in steady operation debris after for a period of time can be ensured, the debris being further ensured that in the space after separating will not be scattered on glass and then ensure the forming quality of glass.
The collection structure includes boss and cleaning brush, and dovetail groove or U-lag are provided with the boss, and the cleaning brush is slidably arranged in dovetail groove or U-lag.In molten tin bath superjacent air space, because the mutual disturbance of high/low temperature gas can cause the impurity in space to fall on glass, shaping to glass causes flaw, particularly to the extra high PDP of glass quality requirement, the glass such as TFT, during long-term practice, staff in the art does not efficiently solve the technical problem of correlation, the present invention is respectively arranged with boss in the bottom both sides of demarcation strip, the impurity produced in the separate space that boss will can be separated is collected, cleared up in concentration after a period of time, dovetail groove or U-lag are provided with boss, and equipped with the cleaning brush adapted to flute profile, staff is facilitated quickly to clear up the debris of accumulation, so that the quality of glass is ensured well, further function as energy-conservation and improve the effect of yield rate.
It is provided with the middle part of the demarcation strip and porous alumina ceramic is filled with heat-insulation chamber, the heat-insulation chamber.The temperature in the preceding several regions in molten tin bath is always held at level higher, then the temperature in several regions is more relatively low, cause energy loss to avoid the temperature between adjacent high-temperature area and low-temperature region from being transmitted by demarcation strip, heat-insulation chamber is provided with the middle part of demarcation strip, and heat-barrier material is filled with cavity, ensure the independence of each separated region, reduce influencing each other for adjacent area.
The present invention compared with prior art, has the following advantages and advantages：
1st, a kind of molten tin bath improved structure for fibrous glass melting furnaces of the invention, floating refuse collecting in the separate space that the collection structure being arranged on the both sides of demarcation strip bottom can be constituted two neighboring demarcation strip, avoiding debris from being scattered on glass influences its quality, improves the raw sheet Forming Quality of glass；
2nd, a kind of molten tin bath improved structure for fibrous glass melting furnaces of the invention, the impurity produced in the separate space that boss will can be separated is collected, cleared up in concentration after a period of time so that the quality of glass is ensured, further functions as energy-conservation and improve the effect of yield rate well；
3rd, a kind of molten tin bath improved structure for fibrous glass melting furnaces of the invention, is provided with heat-insulation chamber in the middle part of demarcation strip, and heat-barrier material is filled with cavity, it is ensured that the independence of each separated region, reduces influencing each other for adjacent area.
