Problems solved by technology
The disadvantage of this kind of integral structure tank kiln is that the length of the melting furnace is long and the total expansion is large, which makes the treatment of the steel structure of the melting furnace complicated and dangerous; in addition, since the clarification part and the melting part are connected together, it cannot Establish the temperature, pressure and atmosphere system required for glass liquid clarification, and the produced glass still contains more microbubbles, which cannot meet the production requirements of high-quality glass, ultra-thin glass or other special glass

Embodiment
[0024] The tank kiln designed by this patent and the traditional glass tank kiln are both composed of melting part 1, clarification part 2, cooling part 3 and collar. The differences are as follows figure 1 and figure 2 As shown, the two parts of the melting part 1 and the clarifying part 2 are independent and separated from each other.
[0025] The clarification part 2 is a closed structure formed by a steel structure supporting refractory materials. In the space above the molten glass in the clarification part 2, a water bag or partition wall separates the inlet and outlet from the front and rear spaces; in order to adjust the clarification part 2. For the internal temperature, an electric heating device is installed inside the clarification section 2 to adjust the temperature of the clarification section; in order to adjust the air pressure inside the clarification section 2, a mechanical exhaust device and a mechanical air supply device are installed inside the clarification ...

The invention relates to the technical field of production equipment for sheet glasses, and in particular relates to a sheet-glass tank furnace structure with an independent clarifying part and an adjusting method of the sheet-glass tank furnace structure. The sheet-glass tank furnace structure comprises a melting part, the clarifying part, necks and a cooling part. The sheet-glass tank furnace structure is characterized in that the melting part, the clarifying part and the cooling part are provided with mutually-independent structures and are intercommunicated by narrow necks. According to the sheet-glass tank furnace structure with the independent clarifying part, the special parameter setting can be implemented based on the independence of a space of the independent clarifying part, such as temperature, pressure and gas requirement, so that the influence of the fluctuation of the parameters of other working areas to a clarifying area can be reduced or avoided; e.g. the clarifying area can be independently treated by pumping air so as to form a negative pressure area, the operation at negative pressure is beneficial for discharging microbubbles in glass melt, and the benefit is provided for producing high-quality glass, ultrathin glass and other special glasses; and the clarifying part is separated from a molten part of the tank furnace, thus the length of a wide section of the tank furnace can be reduced, and the benefit is provided for designing a sheet-glass tank furnace with higher production capacity.
Description
[Technical Field] [0001] The invention relates to the technical field of flat glass production equipment, in particular to a flat glass tank furnace with an independent clarification section structure and a production method thereof, which can meet the requirements for the quality of high-quality glass, ultra-thin glass and other special glass for molten glass . [Background technique] [0002] Glass manufacturing has a history of 5,000 years. In the traditional sense, the production process of glass generally goes through the preparation of raw materials, melting of glass, cooling and molding of glass products, and annealing of glass products. The equipment involved includes melting furnace, Tin bath, annealing kiln and cutting device. [0003] The melting furnace used in the glass melting stage is generally divided into two categories: crucible kiln and pool kiln. Whether it is crucible kiln or pool kiln, it includes four parts: glass melting, heat source supply, waste heat recov...
