Description

The traditional plate glass float process adopts a single melting furnace forming line, and the basic procedures comprise raw material mixing, melting of a melting furnace melting part, cooling of a melting furnace cooling part, tin bath forming, annealing in an annealing furnace, and cutting of a cold end.
The existing one-kiln one-line float glass melting furnace has certain limitation in actual production, particularly, a large-tonnage melting furnace cannot produce thin glass, namely, when the daily drawing amount of the melting furnace is large, the cooling part of the melting furnace cannot produce thin glass. The technical formula of the daily pull quantity of the melting furnace is as follows: daily pull amount = pull speed x average sheet width x average thickness x 24 x 2.5. Wherein, the daily pulling amount is the weight of the glass liquid pulled every day and night, and the unit is t; drawing speed-length of drawing glass original plate in unit time, the unit is m/h; average plate width-average width of raw glass plate in production, unit is m; average thickness-average thickness of glass raw plate in production, unit is m; 24-hours per day and night in h; 2.5-the density of the glass melt in t/m3.
According to the formula, when the daily drawing amount of the one-kiln one-line float glass melting furnace is large, the average thickness of the original glass plate is increased under the condition that the area of the cooling part is certain, and the large-tonnage melting furnace cannot produce thin glass, so that the business variety and the business benefit of enterprises can be adversely affected. The existing production process of one kiln for one line can only achieve nominal production capacity of the melting kiln when glass with specific thickness is produced, and in fact, the melting capacity of the melting kiln is often in an incomplete saturated working state, so that waste of the melting capacity of the melting kiln is caused. Accordingly, the prior art is still in need of improvement and development.

Detailed Description
The technical scheme of the invention is described below with reference to the accompanying drawings and examples.
As shown in fig. 1, a glass melting furnace flow channel according to the present invention comprises a melting furnace 1, a first production line 2 and a second production line 3, wherein the first production line 2 and the second production line 3 are arranged at the outlet end side of the melting furnace 1, the first production line 2 and the second production line 3 are respectively arranged at two sides of the central axis of the melting furnace 1, and the melting furnace 1 is communicated with the first production line 2 and the second production line 3 through a split channel; the interval between the first production line 2 and the central axis of the melting furnace 1 is L1, the pulling amount at the first production line 2 is G1, the interval between the second production line 3 and the central axis of the melting furnace 1 is L2, the pulling amount at the second production line 3 is G2, then L1 is more than L2, and L1: l2=g1: G2.
the molten glass flows from the melting furnace 1 to the first and second production lines 1 and 2 along a split path, and in the split path, the temperature of the molten glass needs to be reduced from 1450 ℃ to about 1150 ℃. In a conventional float glass production line, the length of the shunt path is also fixed at the time of production line design, since the overall length of the production line is limited by the scale of the production site. The daily amount of molten glass in the furnace 1 is calibrated, and the cooling areas of the first line 2 and the second line 3 are calibrated (typically 1.8 x 2.4m,2.4 x 3.6m in relation to the glass web), with the difference that the first line 2 and the second line 3 need to produce glass of different thickness.
For example, the first production line 1 is used for producing thin glass, the drawing amount G1 of the first production line 1 is a calibration value, the cooling area of the first production line 1 is fixed, and the drawing speed is also a design calibration value. The length of the diversion path from the melting furnace 1 to the first production line 1 is insufficient, and a cooling device or a heating device is needed to be added for adjustment so as to meet the temperature requirement when the glass liquid enters the first production line 1, otherwise, the process duration and the production efficiency of the subsequent cooling and shaping procedure can be influenced. In actual production, the productivity of the furnace 1 is excessive, i.e., the daily melting amount of the furnace 1 is far greater than the daily pulling amount of the first production line 1, the waste is relatively large, and the production efficiency is limited.
On the basis, the second production line 3 is added to receive the surplus productivity of the melting furnace 1, and the daily pulling amount G1 of the first production line 2 is subtracted from the daily melting amount of the melting furnace 1 to obtain the daily pulling amount G2 of the second production line 3. Since the first production line 2 and the second production line 3 are arranged on two sides of the melting furnace 1 in parallel, the corresponding diversion paths of the two production lines have equal distances. If the thicknesses of the glass produced by the first production line 2 and the second production line 3 are consistent, the length of the diversion passage can ensure that the temperature reduction amplitude of the glass liquid is normal (the temperature of 1450 ℃ is reduced to 1150 ℃).
And the normal operation of enterprises is to produce glass raw sheets with different specifications, then the first production line 2 is used as a main line to produce products with the largest requirements, and the second production line 3 is used as a collocation to produce glass products with other specifications, so that the daily pulling amount G2 of the second production line 3 is a variable, and G2 is necessarily not equal to G1. The use of two parallel first and second lines 2, 3, with the same length of the shunt path, can result in insufficient shunt path length from the furnace 1 to the second line 3, requiring the addition of cooling or heating devices for adjustment, to meet the temperature requirements of the molten glass entering the second line 3.
According to the invention, a kiln two-line layout is adopted, and the first production line 2 and the second production line 3 are asymmetrically arranged on two sides of the central axis of the melting furnace 1, so that the distances between the two production lines and the central axis of the melting furnace 1 are L1 and L2 respectively, and the lengths of the diversion passages for distributing molten glass are also different. Preferred L1: l2=g1: and G2, by reasonably distributing the lengths of the diversion passages, the diversion passages are matched with the daily pulling quantities G1 and G2 of the first production line 2 and the second production line 3, glass with different thicknesses can be produced at the same time, the production capacity of the large-tonnage melting furnace 1 is fully utilized, the waste is avoided, and the operation competitiveness of enterprises is improved.
The glass liquid temperature in the melting furnace 1 is 1450 ℃, the glass liquid flows to the first production line 2 and the second production line through a diversion passage, the length of the diversion passage between the melting furnace 1 and the first production line 2 is related to the distance L1, and the length of the diversion passage between the melting furnace 1 and the second production line 3 is related to the distance L2.
The daily amount of molten glass in the furnace 1 is a nominal value, and the cooling areas of the first production line 2 and the second production line 3 are constant (typically 1.8 x 2.4m,2.4 x 3.6m, in relation to the glass sheet width), with the difference that the thickness of the glass produced by the first production line 2 and the second production line 3 are different.
The daily melting amount of the melting furnace 1 is R, wherein R is more than or equal to G1+G2, namely, the daily melting amount of the large-tonnage melting furnace 1 is equal to the sum of the pulling amount G1 of the first production line 2 and the pulling amount G1 of the second production line 3, so that the waste of the production capacity of the melting furnace 1 can be avoided. The drawing speed of the glass production line is also usually a fixed value, and is related to the processing efficiency of the subsequent process links of the production line.
Technical formula based on the daily pull quantity:
daily pull amount = pull speed x average sheet width x average thickness x 24 x 2.5.
The first production line 2 is used for producing thin glass, the smaller average thickness is in direct proportion to the daily drawing amount G1, on the premise of a certain drawing speed, the smaller drawing amount G1 means that the heat loss of glass liquid in the flowing process is larger, the separation distance L1 is shortened, the separation path between the melting furnace 1 and the first production line 2 is shortened, the heat loss of the glass liquid in the separation path is reduced, and the glass liquid temperature entering the first production line 2 is ensured to be about 1150 ℃.
Similarly, the second production line 3 is used for producing thick glass, the larger average thickness is in direct proportion to the daily drawing amount G2, on the premise of a certain drawing speed, the larger drawing amount G2 means that the heat loss of the molten glass in the flowing process is smaller, the larger interval L2 is set, the diversion passage between the melting furnace 1 and the second production line 3 is longer, and the temperature of the molten glass entering the first production line 2 is about 1150 ℃.
The melting area of the melting furnace 1 is Sf, the area of the first production line 2 is S1, and Sf: s1=1:0.29; according to the invention, a kiln two-line layout is adopted, the first production line 2 and the second production line 3 are asymmetrically arranged on two sides of the central axis of the melting furnace 1, glass with different thicknesses can be produced at the same time, the production capacity of the large-tonnage melting furnace is fully utilized, the waste is avoided, and the operation competitiveness of enterprises is improved.
The distance between the first production line 2 and the second production line 3 is H which is more than or equal to 15m, and the distance H can ensure that a reasonable maintenance space exists between the two production lines. Meanwhile, L1+L2 is more than or equal to 15m, and a split-flow passage can be reasonably arranged to connect the smelting furnace 1, the first production line 2 and the second production line 3.
The diversion channel comprises a diversion trench 4, a first diversion trench 21 and a second diversion trench 31, and the diversion trench 4 is connected with the outlet end of the melting furnace 1; the two ends of the first diversion trench 21 are respectively connected with the diversion trench 4 and the first production line 2, and the length of the first diversion trench 21 is L1; the two ends of the second diversion trench 31 are respectively connected with the diversion trench 4 and the second production line 3, and the length of the second diversion trench 31 is L2. The diversion channel is composed of two parts, as shown in fig. 1, the diversion trench 4 is connected with the melting furnace 1 along the longitudinal direction, and the first diversion trench 21 and the second diversion trench 31 are arranged along the transverse direction so as to form a three-way structure with the diversion trench 4. The distances L1 and L2 between the first and second production lines 2 and 3 and the central axis of the furnace 1 correspond to the lengths of the first and second diversion trenches 21 and 31. Glass liquid in the melting furnace 1 flows out from the drainage groove 11, and enters the first production line 2 and the second production line 3 respectively through the first diversion groove 21 and the second diversion groove 31, and the flow path lengths of the glass liquid are different, so that the first production line 2 and the second production line 3 can respectively produce glass with different specifications, and L1: l2=g1: and G2, the sum of the pulling amount G1 of the first production line 2 and the pulling amount G1 of the second production line 3 is matched with the large-tonnage smelting furnace 1, so that the waste of the melting capacity of the smelting furnace 1 is avoided, and the production and operation competitiveness of enterprises is improved.
The daily drawing amounts of the first production line 2 and the second production line 3 can be adjusted so as to produce glass with other thickness. It can be understood that, by adjusting the daily pulling amounts G1, G2, the pulling speeds of the first production line 2 and the second production line 3 need to be adjusted in a same ratio, and in L1: l2=g1: on the basis of G2, the lengths of the first diversion trench 21 and the second diversion trench 31 need to be correspondingly adjusted, so that the excessive heat loss of the molten glass on the diversion channel caused by the change of the drawing speed is avoided. When the traditional glass production line solves the problems, a heating component is additionally arranged on the diversion passage to make up for the defect of process temperature.
The technical formula of the solar pulling amount is as follows: daily pull amount = pull speed x average sheet width x average thickness x 24 x 2.5.
Preferably, the diversion passage further comprises a cooling groove 11, and the cooling groove 11 is connected with the outlet end of the melting furnace 1; the first diversion trench 21 and the second diversion trench 31 are arranged along the same axis, and the axis is perpendicular to the central axis of the melting furnace 1; the first end of the diversion trench 4 is movably arranged on the cooling trench 11, and the second end of the diversion trench 4 is movably connected with the first diversion trench 21 or the second diversion trench 31.
The cooling tank 11 is arranged at the outlet end of the melting furnace 1 along the transverse direction, and the glass liquid in the melting furnace 1 firstly enters the cooling tank 11 to reduce the temperature below 1450 ℃, and naturally, the glass liquid passes through the diversion passage and then further reduces the temperature. The guide groove 4 can be laterally adjusted along the cooling groove 11, and simultaneously, the L1 of the first guide groove 21 and the L2 of the second guide groove are changed, thereby satisfying the above L1: l2=g1: g2 requirement.
The foregoing description is only of the preferred embodiments of the invention, and all changes and modifications that come within the meaning and range of equivalency of the structures, features and principles of the invention are therefore intended to be embraced therein.
