Abstract
Description
Technical Field
[0001] The invention relates to the technical field of ultra-white rolled glass production, and in particular to an ultra-white rolled glass melting furnace passage structure and a rolled glass melting furnace. Background Art
[0002] From the latest photovoltaic glass conference, the increase in silicon wafer size has become an inevitable trend in the development of the photovoltaic industry. Large-size silicon wafers can increase the output of silicon wafers, batteries and modules, thereby reducing the production cost per watt. At present, the three modules of 210 modules, 182 modules and 166 modules are conventional modules. The leading enterprises in the industry have established product routes for large-size batteries and modules. Almost all manufacturers' newly built large-size module production capacity is designed as 210 and backward compatible, which also reflects the industry's optimism about the development prospects of 210 modules. The trend of large modules will inevitably affect the supporting of the industrial chain, especially photovoltaic glass, which needs to adapt to the width of the module from the original 1 meter to 1.3 meters. Many glass companies need to layout large-plate width glass to adapt to future trends, while taking into account small-plate width glass, so that an ultra-white rolled glass melting furnace also needs to be compatible with a variety of glass with different plate widths, and the original glass plate width ranges from 2400mm to 4100mm.
[0003] The layout structure of the existing rolled glass melting furnace is usually: after the molten glass passes through the melting part and the neck, it first enters the horizontal main passage, and then is distributed to various longitudinal branch passages according to different product specifications, so as to obtain rolled glass products with different plate width specifications. However, the existing rolled glass melting furnace generally has the following problems:
[0004] (1) The temperature deviation of each longitudinal branch passage is large. Due to the requirements of the molding process, some longitudinal branch passages are arranged at a long distance. The temperature of the glass liquid at the outlet of the branch passage is too low. Additional heating is often required to ensure the quality of the glass, which results in high energy consumption.
[0005] (2) As rolled glass melting furnaces develop towards larger tonnage and larger plate widths, existing rolled glass melting furnaces are increasingly difficult to adapt to branch passage structures of various widths.
[0006] Therefore, how to reduce the energy consumption of the rolled glass melting furnace and ensure the quality of the glass has become a technical problem that needs to be urgently solved by technical personnel in this field. Summary of the invention
[0007] In view of this, the object of the present invention is to provide an ultra-white rolled glass melting furnace passage structure and a glass melting furnace to solve the technical problem of high energy consumption of existing rolled glass melting furnaces.

[0014] Beneficial effects of the present invention:
[0015] The present invention adopts a variable diameter structure. By increasing the longitudinal dimension of the middle section of the transverse main passage, not only can more glass liquid enter the transverse main passage, directly increasing the temperature of the glass liquid in the transverse main passage, but also indirectly increasing the temperature of the glass liquid in the longitudinal branch passage, solving the problem of low temperature of the glass liquid at the outlet of the branch passage caused by the process layout and the excessive length of the passage, thereby reducing energy consumption, but also can increase the area of the intersection of multiple glass liquid flows, alleviate the flow rate of the glass liquid, reduce the influence between each glass liquid flow, improve the uniformity of the glass liquid, and thus improve the glass forming quality, and at the same time can effectively reduce the scouring of the pool wall by the glass liquid, reduce the erosion of the pool wall, improve safety, and reduce production costs.

[0034] Preferably, L1 is 1.2-1.8 times of L2.
[0035] More preferably, L1 is 1.5 times of L2, for example, L1=6m, L2=4m.
[0036] A middle arch 17 is fixedly connected between the opposite breast wall of the middle section 11 and the neck side breast wall 14, a side arch 18 is connected between the opposite breast wall of the side section 12 and the neck side breast wall 14, and a sealing brick 19 is filled in the gap between the opposite breast wall of the middle section 11 and the opposite breast wall of the side section 12, and the top of the sealing brick 19 is sealed and connected to the middle arch 17.
[0037] A glass liquid inlet 13 is provided on the longitudinal left side of the middle section 11 (the side close to the neck), and a longitudinal branch passage 20 is provided on the longitudinal right side of the middle section 11; the longitudinal branch passage 20 includes two middle branch passages 21 and multiple side branch passages 22, the side branch passages 22 are located on the lateral sides of the middle section 11, and the side branch passages 22 are vertically connected with the side section 12, and the two middle branch passages 21 are vertically connected with the lateral ends of the middle section 11 one by one.
[0038] Preferably, the glass liquid inlet 13 is arranged in the lateral middle position of the middle section 11, and the two middle branch passages 21 are symmetrically arranged on the lateral sides of the glass liquid inlet 13, and the glass liquid inlet 13 is opposite to the transverse passage breast wall between the two middle branch passages 21, that is, the opposite side breast wall of the middle section 11 is fixedly connected between the two middle branch passages 21, and the opposite side breast wall of the middle section 11 is opposite to the glass liquid inlet 13, and the lateral dimension of the opposite side breast wall of the middle section 11 is not less than the lateral dimension of the glass liquid inlet 13.
[0039] More preferably, the lateral dimension of the middle branch passage 21 is smaller than the lateral dimension of the side branch passage 22 .
[0040] Embodiment 2, as Figure 3 As shown, a rolled glass melting furnace includes the above-mentioned passage structure, a melting section 30, an edge rolled glass forming device 40, and a middle rolled glass forming device 50. One longitudinal end of the melting section 30 is fixedly connected to the glass liquid inlet 13 through a neck so that the glass liquid in the melting section 30 flows into the transverse main passage 10. The edge rolled glass forming device 40 is arranged at one end of the edge branch passage 22, and the middle rolled glass forming device 50 is arranged at one end of the middle branch passage 21, and the lateral dimension of the middle branch passage 21 is smaller than the lateral dimension of the edge branch passage 22.
[0041] The working principle of the passage structure of the present invention is as follows:
[0042] After the glass liquid flows out of the bottleneck, it enters the middle section of the transverse main passage. Compared with the transverse main passage structure of the same size, the widened middle section allows more glass liquid to flow into the transverse main passage. The increased glass liquid can bring in more heat, which is beneficial to increase the temperature of the glass liquid in the transverse main passage and the longitudinal branch passage, and can solve the problem of low temperature of the glass liquid at the outlet of the subsequent branch passage.
[0043] At the intersection of the bottleneck and the main passage, there are often multiple middle branch passage liquid flows intersecting, and multiple streams of molten glass form a relatively chaotic and complex circulation, which is not conducive to the homogenization of the molten glass; by increasing the width of the middle section of the transverse main passage connected to the bottleneck, the flow rate of the molten glass can be alleviated, the influence between the multiple streams of molten glass can be reduced, the homogenization of the molten glass can be improved, and the quality of glass products can be improved.
[0044] The side sections of the transverse main passage have smaller longitudinal dimensions, which can not only adapt to different product specifications and width requirements of each branch passage, but also reduce the heat dissipation area, which is beneficial to reducing energy consumption.
[0045] In a rolled glass melting furnace, it is often necessary to configure rolling branches for large-tonnage and large-width glass at the sides of the horizontal main passage, and to configure some rolling branches for small-width glass in the middle of the horizontal main passage. Different main passage widths can be configured according to different plate width requirements and glass liquid flow requirements to meet the rolled glass requirements of future 210 components.
[0046] Compared with the prior art, this application has at least the following beneficial technical effects:
[0047] The present invention appropriately increases the area of the intersection of multiple glass liquid flows, reduces the influence between the multiple glass liquid flows, can improve the uniformity of the glass liquid, make the glass liquid flows flowing into the main passage and the branch passage more uniform, and thus improve the glass quality.
[0048] The present invention allows more molten glass to flow into the transverse main passage, directly increases the temperature of the molten glass in the transverse main passage, and indirectly increases the temperature of the molten glass at the outlet of the branch passage, thereby solving the problem of low outlet temperature of the branch passage caused by process layout and too long passage.
[0049] The present invention adopts a variable diameter transverse main passage structure, which can better and more flexibly adapt to rolled glass with various plate widths, especially rolled glass with large tonnage and large plate width in the future.
[0050] The present invention widens the middle section of the transverse main passage facing the neck, which can effectively reduce the scouring of the pool wall nearby by the glass liquid, reduce the erosion of the pool wall, improve safety, and appropriately configure more economical pool wall bricks, thereby reducing production costs.
[0051] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
