The embodiment of the utility model provides a float glass melting furnace.
In one embodiment of the present invention, as shown in fig. 2 and 3, the float glass melting furnace includes:
a melting section 100;
a main line cooling part 300, wherein the main line cooling part 300 is communicated with the melting part 100 through a neck 200, and a first transverse passage 400 and a second transverse passage 500 are respectively communicated with two sides of the main line cooling part 300; and the number of the first and second groups,
a first branch line cooling part 600 and a second branch line cooling part 700 respectively provided at both sides of the main line cooling part 300, the first branch line cooling part 600 communicating with the first transverse passage 400, and the second branch line cooling part 700 communicating with the second transverse passage 500.
It should be noted that float glass is so named that molten glass floats on the surface of molten metal and is polished and shaped, and molten glass continuously flows into a furnace filled with a protective gas (N)2And H2) The tin bath floats on the liquid surface of the metallic tin, and the glass of the glass belt with uniform thickness, parallel two surfaces, flatness and polishing is formed by flattening and polishing, which is one of plate glass (plate silicate). The melting process of the float glass is one of the main stages in the manufacturing process of the float glass, namely the process of heating qualified batch at high temperature to form uniform, pure and transparent glass liquid which meets the forming requirement. The melting furnace is the place where the float glass melting process occurs. Specifically, the glass melting process can be summarized into the following stages: silicate forming stage-molten glass clarifying stage-molten glass homogenizing stage-molten glass cooling stage.
The existing one-kiln one-line float glass melting furnace has certain limitation in practical production, and particularly, a large-tonnage melting furnace cannot produce thin glass, namely, when the daily drawing amount of the melting furnace is large, a cooling part of the melting furnace cannot produce the thin glass. Wherein, the technical formula of the daily drawing amount of the melting furnace is as follows:
daily drawing amount is drawing speed × average sheet width × average thickness × 24 × 2.5
Wherein the daily drawing amount-the weight of glass liquid drawn every day and night is t;
drawing speed-the length of the glass original plate in unit time, and the unit is m/h;
average sheet width-the average width of the glass raw sheet in production, in units of m;
average thickness-the average thickness of the glass raw sheet in production, in m;
24-hours per day and night in units of h;
2.5-density of the molten glass, unit t/m3。
From the above formula, it can be understood that when the daily draw amount of the float glass melting furnace is large and the area of the cooling part is constant, the average thickness of the glass base plate is increased. Therefore, the large-tonnage melting furnace cannot produce thin glass, and the operation variety and the operation benefit of enterprises are adversely affected.
On the basis of the traditional large-tonnage one-kiln one-line float glass melting furnace, the technical scheme of the embodiment forms a new one-kiln three-line float glass melting furnace by adding transverse passages at two sides and branch cooling parts at two sides of the main line cooling part 300. The drawing amount of the molten glass of the main line cooling part 300 and the branch line cooling part is reasonably distributed, so that the drawing amount of the molten glass of the main line cooling part 300 is reduced, the aim of producing thin glass by the main line is fulfilled, and meanwhile, the forming temperature of the molten glass of the branch line cooling part can be met by increasing the convection amount of the molten glass of the branch line cooling part.
It can be understood that the main line is designed as a thin glass production line, and the residence time of the molten glass in the main line cooling part 300 is long due to the small drawing amount, so that good clarifying and homogenizing effects of the molten glass can be achieved, and the forming quality of the thin glass in the main line cooling part 300 is improved. In addition, the initial forming temperature of the molten glass is generally about 1050 ℃, and because a transverse passage is additionally arranged between the branch cooling part and the main cooling part 300, when the molten glass in the branch cooling part passes through the transverse passage, the heat dissipation amount of the molten glass naturally cooled is increased, and the forming temperature of the molten glass at the outlet of the branch cooling part is low, so that the heat conduction of the molten glass in the branch cooling part is increased by increasing the convection amount of the molten glass in the branch cooling part, and finally the forming temperature of the molten glass in the branch cooling part is met.
In the technical scheme of the embodiment, the main line cooling part is used for producing thin glass, and the branch line cooling parts on two sides are used for producing glass with conventional thickness. Whether the main line or the branch line can produce thin glass is mainly determined by the amount of drawing of the main line and the branch line and the temperature of the forming process of the molten glass in the main line cooling section 300 and the branch line cooling section. The main line is designed into a thin glass production line, because the drawing amount of the main line cooling part 300 is small, the convection flow of the glass liquid of the main line cooling part 300 is reduced, the clarification, homogenization and cooling effects of the glass liquid of the main line cooling part 300 are facilitated, and the convection flow of the glass liquid of the branch line cooling part is increased, so that the forming temperature of the glass liquid of the branch line cooling part is increased, and the process requirements of the main line cooling part 300 for producing thin glass and the branch line cooling part for producing conventional glass are met. Of course, in other embodiments, the two-sided spur cooling section may also be used to produce thin glass.
In one embodiment, as shown in fig. 2 and 3, the first and second transverse passages 400 and 500 are both communicated with the front half section of the main line cooling part 300. In the technical scheme of the embodiment, the transverse passages on the two sides are communicated with the front end of the main line cooling part 300, so that molten glass can be divided into the transverse passages on the two sides when the molten glass just flows into the main line cooling part 300, and the excessive temperature drop before the molten glass flows into the branch line cooling part is avoided, so that the forming temperature of the molten glass in the branch line cooling part can be met.
In another embodiment, the lateral passages on both sides may be communicated with the middle section or the rear half section of the main line cooling part 300, and the present invention does not limit the relative positions of the lateral passages on both sides and the main line cooling part 300.
In one embodiment, as shown in fig. 2 and 3, the area of the first branch line cooling part 600 and the area of the second branch line cooling part 700 are both smaller than the area of the main line cooling part 300. It is understood that in the present embodiment, the main line cooling unit is used to produce thin glass, and the branch line cooling units on both sides are used to produce conventional glass, and by increasing the area of the main line cooling unit 300 (i.e. increasing the average sheet width of the glass original sheet), it is advantageous to reduce the average thickness of the glass original sheet under a constant daily drawing amount of the melting furnace, thereby facilitating the main line cooling unit 300 to produce thin glass.
In this embodiment, the area of the first branch cooling part 600 is the same as that of the second branch cooling part 700, so that the drawing amount of the branch cooling parts located at both sides of the main line cooling part 300 is the same, which is beneficial to the uniform outflow of the molten glass in the main line cooling part 300 from both sides, thereby being beneficial to the improvement of the clarification, homogenization and cooling effects of the molten glass in the main line cooling part 300.
In another embodiment, the area of the first branch line cooling part 600 is different from the area of the second branch line cooling part 700, but the areas of both branch line cooling parts 600 are smaller than the area of the main line cooling part 300.
In another embodiment, the areas of the main line cooling unit 300, the first branch line cooling unit 600, and the second branch line cooling unit 700 may be the same, that is, the drawing amounts of the two branch line cooling units and the main line cooling unit are the same, and all of them may be used to produce thin glass.
In the present embodiment, as shown in fig. 2 and 3, a connection port of the neck 200 to the main line cooling unit 300 is formed to be flared toward the main line cooling unit 300. Specifically, a diversion angle is arranged at the tail end of the neck 200, and the diversion angle adopts a chamfer structure, so that the glass liquid is guided to flow into the main line cooling part 300 from the neck 200, and the retention of the glass liquid at the neck 200 is reduced.
In one embodiment, as shown in fig. 2 and 3, the central axis of the melting part 100 coincides with the central axis of the main line cooling part 300, so that on one hand, the molten glass in the melting part 100 can smoothly flow into the main line cooling part 300, and on the other hand, the reasonable layout of the melting, forming, annealing and cold end processes of the three-line float glass production line is facilitated.
In another embodiment, the central axis of the melting section 100 and the central axis of the main line cooling section 300 may be offset, i.e., the central axes of the two do not coincide, and it can be understood that the glass flow in the melting section 100 is not affected to flow into the main line cooling section 30 as long as the central axes of the two are not spaced apart from each other.
In one embodiment, the central axis of the first transverse passage 400 and the central axis of the second transverse passage 500 are perpendicular to the central axis of the main cooling part 300. That is, the lateral passages on both sides of the main line cooling part 300 are perpendicular to the main line cooling part 300, which is not only beneficial to smoothly flow the molten glass from the main line cooling part 300 to the lateral passages on both sides, but also beneficial to shorten the length of the lateral passages, and avoids the molten glass from being cooled too much when passing through the lateral passages, thereby reducing the forming quality of the molten glass in the branch line cooling part.
In another embodiment, the lateral passages on both sides of the main line cooling part 300 may not be perpendicular to the main line cooling part 300, or one of the lateral passages is perpendicular to the main line cooling part 300, and the other lateral passage is not perpendicular to the main line cooling part, which is not limited in the present invention.
Further, the central axis of the first transverse passage 400 and the central axis of the main line cooling part 300 are arranged at an acute angle; and/or the central axis of the second transverse passage 500 is disposed at an acute angle with respect to the central axis of the main line cooling part 300. It can be understood that the transverse passage may be disposed at an acute angle with respect to the main line cooling part 300, and the transverse passage is disposed at an inclination toward the rear end of the main line cooling part 300, so that the molten glass in the main line cooling part 300 can rapidly flow to the transverse passage and the branch line cooling part, thereby advantageously increasing the forming temperature of the molten glass in the branch line cooling part.
In one embodiment, as shown in fig. 2 and 3, the first and second transverse passages 400 and 500 are symmetrically disposed about a central axis of the main line cooling part 300. Therefore, the convection of the molten glass in the two transverse passages is facilitated, the heat conduction of the molten glass in the branch cooling part is increased, and the forming of the molten glass in the branch cooling part is facilitated. Further, the central axis of the first transverse passage 400 coincides with the central axis of the second transverse passage 500, which is beneficial for the molten glass in the main line cooling part 300 to flow out from two sides simultaneously, so that the clarification, homogenization and cooling effects of the molten glass in the main line cooling part 300 can be rapidly improved. Of course, in other embodiments, the central axis of the first transverse passage 400 and the central axis of the second transverse passage 500 may not coincide, but the two transverse passages may be disposed symmetrically with respect to the central axis of the main line cooling part 300.
In another embodiment, the first transverse channel 400 is asymmetrically disposed with respect to the second transverse channel 500. It can be understood that although the transverse passages on both sides of the main line cooling part are asymmetrically disposed, the molten glass in the main line cooling part 300 can still be distributed into the transverse passages on both sides, which has the effect of reducing the drawing amount of the main line cooling part 300.
In one embodiment, the first branch line cooling part 600 and the second branch line cooling part 700 are symmetrically disposed about the central axis of the main line cooling part 300. According to the technical scheme, the branch cooling parts positioned on the two sides of the main line cooling part 300 are symmetrically arranged, so that the reasonable layout of melting, forming, annealing and cold end processes of a one-kiln three-line float glass production line is facilitated, the glass liquid in the main line cooling part 300 can uniformly flow out from the two sides, and the clarification, homogenization and cooling effects of the glass liquid in the main line cooling part 300 are further improved.
Further, the central axis of the first branch line cooling part 600 and the central axis of the first lateral passage 400 are perpendicular to each other; the central axis of the second branch line cooling part 700 and the central axis of the second transverse passage 500 are perpendicular to each other. That is, the first branch line cooling unit 600, the main line cooling unit 300, and the second branch line cooling unit 700 are parallel to each other. Of course, in other embodiments, the central axis of the first sub-line cooling part 600 and the central axis of the first transverse passage 400 are not perpendicular to each other, and the central axis of the second sub-line cooling part 700 and the central axis of the second transverse passage 500 are not perpendicular to each other, but the two sub-line cooling parts can still be disposed symmetrically with respect to the central axis of the main line cooling part 300.
In another embodiment, the first branch line cooling part 600 and the second branch line cooling part 700 are disposed asymmetrically. It can be understood that although the branch cooling portions located on both sides of the main line cooling portion are asymmetrically disposed, the molten glass in the main line cooling portion 300 can still be distributed to the branch cooling portions on both sides, which has the effect of reducing the drawing amount of the main line cooling portion 300.
Further, as shown in fig. 3, a distance L between the central axis of the first branch line cooling part 600 and the central axis of the main line cooling part 3001Range, distance L between central axis of second branch line cooling part 700 and central axis of main line cooling part 3002The range is 15-30 m. Namely, the length of the two lateral passages ranges from 15 to 30m, and alternatively, the length of the two lateral passages may be 15m, 22m, 25m, 30m, and the like, respectively. The length range of the transverse passages on the two sides is determined by factors such as the designed drawing amount of the melting furnace, the process layout of forming equipment, the specification of glass products and the like. It can be understood that if the length of the transverse passages on the two sides is too short, the reasonable process layout requirement of the branch line cannot be met; if the length of the transverse passages on the two sides is too long, the glass liquid is cooled too much when passing through the transverse passages, so that the temperature of the glass liquid of the two branch cooling parts is lower, the temperature difference between the left side and the right side as well as the upper side and the lower side of the glass liquid of the cross section of the flow passage is larger, and the glass quality can not meet the requirement of the engineering-grade glass quality.
Preferably, the length of the lateral passages on both sides is in the range of 15 to 22m, and it can be understood that the shorter the length of the lateral passages on both sides, the easier it is to satisfy the forming temperature of the molten glass in the branch cooling section, but if the length of the lateral passages is too short, it is not favorable for the placement and layout of the branch cooling section. Therefore, the technical scheme of the embodiment further limits the length range of the transverse passages on the two sides so as to reasonably arrange the branch cooling part at the same time under the condition of ensuring the forming temperature of the glass of the branch cooling part.
The embodiment of the utility model also provides a float glass production line which comprises the float glass melting furnace and a tin bath, wherein the tin bath is communicated with the float glass melting furnace. In this embodiment, the float glass melting furnace includes three cooling portions, which are a main line cooling portion 300 and two branch line cooling portions, respectively; the number of the tin baths is correspondingly set to be three, and the three tin baths are correspondingly communicated with the three cooling parts one by one. The specific structure of the float glass melting furnace refers to the above embodiments, and the float glass production line adopts all the technical schemes of all the above embodiments, so that the float glass melting furnace at least has all the beneficial effects brought by the technical schemes of the above embodiments, and details are not repeated herein.
The above description is only an alternative embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
