Description

Technical Field

[0001] This utility model relates to the field of glass technology, and in particular to a photovoltaic rolled glass melting furnace. Background Technology

[0002] In related technologies, photovoltaic rolled glass melting furnaces are used to produce photovoltaic rolled glass. Specifically, the process flow of a photovoltaic rolled glass melting furnace is as follows: molten glass is melted in the melting section, and then the molten glass passes through a chuck into a transverse passage. The transverse passage connects to various branch passages. After flowing through the transverse passage, the molten glass enters each branch passage and then enters each overflow port. The glass is then formed into glass sheets of a certain size through a rolling mill forming process.

[0003] Furthermore, due to the need for differentiated production, photovoltaic rolling glass melting furnaces are required to produce glass sheets of different thicknesses and widths. The overflow temperature required varies depending on the glass production line. The overflow temperature of the molten glass primarily originates from the temperature of the melting section, and the melting temperature directly determines the overflow temperature. Specifically, current methods for regulating the temperature of the molten glass mainly involve adjusting the overall temperature of the melting section. However, due to the large space within the melting section, adjusting its temperature results in high energy consumption and low temperature control precision. Utility Model Content

However, in this application, since the isolation members isolate the branch passages, it is only necessary to adjust the temperature inside the branch passages to control the temperature of the overflow glass melt, which can effectively avoid the problems of excessive energy consumption and poor temperature adjustment accuracy. In particular, the photovoltaic rolled glass melting furnace can effectively reduce energy consumption and effectively improve the accuracy of temperature adjustment.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0031] In related technologies, the photovoltaic rolled glass melting furnace 10 is used to produce photovoltaic rolled glass. Specifically, the process flow of the photovoltaic rolled glass melting furnace 10 is as follows: molten glass is melted in the melting section 200, and then the molten glass enters the transverse passage through the neck 100. The transverse passage connects to each branch passage 400. After flowing through the transverse passage, the molten glass enters each branch passage 400 and then enters each overflow port 900. The glass is then formed into glass sheets of a certain specification through the rolling mill forming process.

[0032] Furthermore, due to the need for differentiated production, the photovoltaic rolled glass melting furnace 10 needs to produce glass sheets of different thicknesses and widths. The overflow port 900 temperature required varies depending on the glass production line. The temperature of the molten glass at the overflow port 900 mainly originates from the temperature of the melting section 200, and the melting temperature directly determines the temperature of the overflow port 900. Specifically, existing methods for adjusting the temperature of the molten glass primarily involve adjusting the overall temperature of the melting section 200. However, due to the large space of the melting section 200, adjusting its temperature results in high energy consumption and low temperature control accuracy. Therefore, this application proposes a photovoltaic rolled glass melting furnace 10.

[0033] Please refer to Figure 1 and Figure 2In some embodiments, the photovoltaic rolled glass melting furnace 10 includes: a neck 100, a melting section 200, a main passage 300, and a branch passage assembly. The melting section 200 is used to melt raw materials. For example, the melting section 200 is used to melt batch materials (quartz sand, soda ash, limestone, etc.) into molten glass at 1500-1600°C. The neck 100 is used to prevent the low-temperature molten glass from flowing back into the melting section 200 from the cooling section. The two ends of the neck 100 are connected to the main passage 300 and the melting section 200, respectively. That is, molten glass can pass through the neck 100 from the melting section 200 and then enter the main passage 300. The branch passage assembly includes a branch passage 400 and two isolation members 500. The branch passage 400 is connected to the main passage 300, and the two isolation members 500 are connected to the beginning and end of the branch passage 400, respectively, to isolate the internal space of the branch passage 400. The branch passage 400 is provided with an overflow port 900. Specifically, the photovoltaic rolled glass melting furnace 10 includes a main passage 300 and branch passage components. Branch passages 400 are connected to the main passage 300, and isolation members 500 are connected to the beginning and end of the branch passages 400 respectively, isolating the internal space of the branch passages 400. Specifically, in the prior art, when it is necessary to adjust the temperature of the molten glass at the overflow port 900, the temperature is adjusted in the melting section 200, which leads to excessive energy consumption and poor temperature control accuracy. In this application, because the isolation members 500 isolate the branch passages 400, the temperature of the molten glass at the overflow port 900 can be controlled solely by adjusting the temperature inside the branch passages 400. This effectively avoids the problems of excessive energy consumption and poor temperature control accuracy. In essence, the photovoltaic rolled glass melting furnace 10 can effectively reduce energy consumption and effectively improve the accuracy of temperature control.

[0034] Furthermore, the specific way in which the isolator 500 connects to and blocks the branch passage 400 can be that the isolator 500 can be a baffle wall, with the first and last ends of the branch passage 400 set by the baffle wall. The baffle wall can be a suspended wall structure, with specially reserved space for molten glass to enter the branch passage 400 from the main passage 300, and the baffle wall can block most of the heat. Thus, only the molten glass inside the branch passage 400 needs to be controlled, which can significantly reduce energy consumption and improve temperature control accuracy. Furthermore, the specific way in which the isolator 500 connects to the branch passage 400 can also be that the isolator 500 is movably connected to the branch passage 400. That is, when it is necessary to block the interior of the branch passage 400, the isolator 500 is moved to block it; when it is not necessary to block the branch passage 400, the isolator 500 can be removed.

[0035] Furthermore, the following describes how to regulate the temperature of the molten glass inside the branch passage 400 after it has been isolated, such as raising or lowering the temperature of the molten glass. For details, please refer to... Figure 1and Figure 2 In some embodiments, the branch passage assembly further includes a heating system 600 connected to the branch passage 400, which is used to heat the branch passage 400. Specifically, the heating system 600 can heat the molten glass inside the branch passage 400 via electric heating or gas heating, thereby ensuring that the temperature of the molten glass meets the processing requirements. For example, a through-hole is provided in the wall of the branch passage 400, and a torch is installed in the through-hole. Natural gas is then introduced to heat the molten glass. When introducing natural gas into the torch, the flow rate can be adjusted using a flow valve to achieve precise heating of the molten glass in the branch passage 400.

[0036] Further, please refer to Figure 1 and Figure 2 In some embodiments, two heating systems 600 are provided, each connected to one side of the branch passage 400 along its length. Specifically, with the two heating systems 600 connected to both sides of the branch passage 400 along its length, they can uniformly heat the molten glass, effectively increasing its temperature. Furthermore, the symmetrical arrangement of the two heating systems 600 can effectively prevent temperature variations at different locations within the molten glass.

[0037] Furthermore, the above describes how to heat the branch passage 400 to increase the temperature of the molten glass. The following describes how to cool the molten glass in the branch passage 400 when the temperature is too high and does not meet processing requirements. For details, please refer to... Figure 1 and Figure 2 In some embodiments, the branch passage assembly further includes a cooling system 700 connected to the branch passage 400, which is used to cool the branch passage 400. The cooling system 700 cools the branch passage 400 using either air cooling or water cooling, ensuring that the temperature of the molten glass in the branch passage 400 meets processing requirements. For example, a through-hole is provided in the wall of the branch passage 400, and an air duct is installed in the through-hole. Diluting air is then introduced to cool the molten glass. When diluting air is introduced into the air duct, the frequency of the fan motor can be used to control the air cooling of the diluting air, thereby achieving precise cooling of the molten glass in the branch passage 400.

[0038] Further, please refer to Figure 1 and Figure 2In some embodiments, two cooling systems 700 are provided, each connected to one side of the branch passage 400 along its length. Specifically, after the two cooling systems 700 are connected to the other side of the branch passage 400 along its length, they can uniformly cool the molten glass, effectively reducing its temperature. Furthermore, the symmetrical arrangement of the two cooling systems 700 can effectively prevent temperature differences at different locations within the molten glass.

[0039] Further, please refer to Figure 1 and Figure 2 In some embodiments, the branch assembly also includes a chimney 800 connected to the branch passage 400. The chimney 800 can be used to adjust the internal pressure of the branch passage 400, thereby maintaining a stable internal pressure and avoiding interference with the overflow port 900 process. Specifically, a switch valve can be installed at the chimney 800, allowing the valve to be opened or closed as needed, which improves the flexibility of the chimney 800's use.

[0040] Further, please refer to Figure 1 and Figure 2 In some embodiments, two chimneys 800 are provided, with each chimney 800 connected to one side of the branch passage 400 along its length. Specifically, the two chimneys 800 can better regulate the internal pressure of the branch passage 400, thereby improving the yield of photovoltaic rolled glass production.

[0041] Further, please refer to Figure 1 In some embodiments, multiple branch components are provided, and all multiple branch components are connected to the main passage 300. Specifically, there may be two, three, four, five, or six branch components. The provision of multiple branch components can significantly improve the production efficiency of the photovoltaic rolled glass melting furnace 10.

[0042] Further, please refer to Figure 1 In some embodiments, the lengths of the branch passages 400 are not equal. For example, the branch assembly can have five branches, thus there are also five branch passages 400. The lengths of each of the five branch passages 400 are different. It is conceivable that the longer the branch passage 400, the greater the temperature drop of the molten glass after passing through it. That is, when the molten glass passes through a shorter branch passage 400, the temperature drop is smaller, and when the molten glass passes through a longer branch passage 400, the temperature drop is larger. Thus, by setting branch passages 400 of different lengths, the temperature of the molten glass can be made to meet the needs of different types of glass production.

[0043] Further, please refer to Figure 1In some embodiments, multiple branch components are spaced apart along the length of the main passage 300. Specifically, the spaced-apart arrangement of multiple branch components along the length of the main passage 300 effectively utilizes space, thereby saving costs. Furthermore, it should be noted that the spacing between the multiple branch components is equal.

[0044] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
