Description

Technical Field

[0001] The utility model relates to the technical field of glass production and manufacturing, in particular to an edge fire combustion auxiliary device for photovoltaic glass. Background Art

[0002] Photovoltaic glass is a special type of glass that incorporates solar photovoltaic modules, generating electricity from solar radiation and equipped with current extraction devices and cables. Photovoltaic glass is typically produced using a rolling process. Its production process consists of two main steps: raw sheet production and further processing. Raw sheet production involves mixing, melting, rolling, annealing, and cutting raw materials to produce unprocessed semi-finished photovoltaic sheets, which then undergo further processing.

[0003] Sheet production involves five steps: batching, melting, forming, annealing, and edge inspection. Melting, forming, and annealing are the core components of the sheet production line; any failure in any of these steps can negatively impact product quality and yield. Glass production is highly continuous, and substandard photovoltaic glass products must be remelted and remanufactured, incurring additional costs for manufacturers. Sheet production operates 24 / 7, requiring no downtime. Unstable product quality can disrupt normal production.

[0004] Before the glass sheets are transported to the annealing furnace for the annealing process, they need to undergo a rolling process in the furnace. The rolling process is mainly completed in the calender. The performance of the calender and the control of the lateral temperature difference are the decisive factors for the quality of this process. Currently, in the production of photovoltaic glass sheets, when the calender fails and causes a large temperature difference between the lateral side and the middle of the glass sheet, the glass sheets that have undergone the rolling process are still directly transported to the annealing furnace for annealing, resulting in insufficient quality of the finished glass. At this time, production needs to be interrupted, resulting in significant losses. Therefore, there is an urgent need for a side fire combustion auxiliary device that can compensate for the temperature of the glass sheets along the lateral side after rolling. Utility Model Content

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the defect in the prior art that there is a lack of an edge fire combustion auxiliary device that can compensate for the temperature of the rolled glass sheet along the lateral side, thereby providing a photovoltaic glass edge fire combustion auxiliary device.

[0040] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0041] like Figure 1 The embodiment shows a photovoltaic glass edge fire combustion auxiliary device, which is used between a kiln and an annealing furnace. The edge fire combustion auxiliary device includes a natural gas edge fire combustion auxiliary component, and the natural gas edge fire combustion auxiliary component includes a first gas uniform distributor 1, the air inlet of the first gas uniform distributor 1 is connected to a gas pipeline; the air outlet of the first gas uniform distributor 1 is connected to a first gas branch pipe 2, and the end of the first gas branch pipe 2 facing away from the first gas uniform distributor 1 is connected to a burner, and the burner is used to heat the lateral side of the glass sheet; the first gas branch pipe 2 is provided with a first ball valve 21. The conveying direction described in the text is perpendicular to the lateral direction, and the conveying direction and the lateral direction are located in the same horizontal plane. The conveying direction refers to Figure 1 The conveying direction in .

[0042] The edge fire combustion auxiliary device of this embodiment is achieved by arranging a burner between the kiln and the annealing kiln, and the burner is connected to the outlet of the first gas distributor 1 through a first gas supply branch pipe 2 with a first ball valve 21. When a malfunction of the calendering machine causes the temperature difference between the lateral side and the middle of the glass sheet to be too large, the operator can flexibly adjust the opening of the first ball valve 21 according to the actual temperature difference, that is, control the amount of gas delivered to the burner per unit time, thereby adjusting the heat output by the burner to the lateral side of the glass sheet, performing heat compensation on the lateral side of the glass sheet so that the temperature of the lateral side of the glass sheet rises, and reducing the temperature difference between the lateral side of the glass sheet and the middle of the glass sheet to meet the requirements of high-quality annealing, ensuring that there is no need to interrupt production when a malfunction of the calendering machine causes a large temperature difference between the lateral side and the middle of the glass sheet, thereby ensuring the continuity of production and avoiding large economic losses. A first gas distributor 1 is also connected between the first gas branch pipe 2 of the natural gas edge fire combustion auxiliary component and the gas pipeline. The first gas distributor 1 can evenly distribute the gas entering from the air inlet over the entire cross-section of the first gas distributor 1, thereby stabilizing the gas before entering the first gas branch pipe 2, ensuring that the burner stably outputs the set heat to the lateral side of the glass sheet, thereby ensuring that the temperature difference between the lateral side of the glass sheet and the middle of the glass sheet is reduced to meet the requirements of high-quality annealing.

[0043] Optionally, the first gas distributor 1 is provided with multiple gas outlets, and the multiple gas outlets of the first gas distributors 1 are connected to a corresponding first gas branch pipe 2. Each of the first gas branch pipes 2 is connected to a burner at one end facing away from the first gas distributor 1, and the multiple burners are arranged at intervals along the conveying direction of the glass sheet. By arranging multiple gas outlets at intervals along the conveying direction of the glass sheet on the first gas uniform distributor 1, and each gas outlet of the first gas uniform distributor 1 is connected to a burner through a first gas supply branch pipe 2 with a first ball valve 21, when a malfunction of the calendering machine causes the temperature difference between the lateral side and the middle of the glass sheet to be too large, the operator can flexibly adjust the opening of the first ball valve 21 located at different positions along the conveying direction according to the actual temperature difference, that is, control the amount of gas delivered to the burner per unit time, thereby adjusting the heat output by the burner to the lateral side of the glass sheet, performing heat compensation on the lateral side of the glass sheet so that the temperature of the lateral side of the glass sheet rises, and reducing the temperature difference between the lateral side of the glass sheet and the middle of the glass sheet to meet the requirements of high-quality annealing, ensuring that there is no need to interrupt production when a malfunction of the calendering machine causes a large temperature difference between the lateral side and the middle of the glass sheet, thereby ensuring the continuity of production and avoiding large economic losses. A first gas distributor 1 is also connected between multiple first gas branches 2 of the natural gas edge fire combustion auxiliary component and the gas pipeline. The first gas distributor 1 can evenly distribute the gas entering from the air inlet over the entire cross-section of the first gas distributor 1, thereby stabilizing the gas before entering each first gas branch 2, and ensuring that the amount of gas delivered to the first gas branch 2 located at different positions along the delivery direction is basically the same, ensuring that the burners located at different positions along the delivery direction stably output the same heat to the lateral side of the glass sheet, thereby ensuring that the temperature difference between the lateral side of the glass sheet and the middle of the glass sheet is reduced to meet the requirements of high-quality annealing.

[0044] It can be understood that when the temperature difference between the lateral side and the middle of the glass sheet output from the kiln exceeds the standard temperature difference for ensuring annealing quality by a smaller amount, the first ball valves 21 of part of the first gas branch pipes 2 of the natural gas edge fire combustion auxiliary assembly can be closed, and only the first ball valves 21 of part of the first gas branch pipes 2 are left open at the set opening; when the temperature difference between the lateral side and the middle of the glass sheet output from the kiln exceeds the standard temperature difference for ensuring annealing quality by a larger amount, all the first ball valves 21 of the natural gas edge fire combustion auxiliary assembly can be opened at the set opening.

[0045] It's understandable that existing photovoltaic glass is formed using the calendering method. Molten glass flows from the furnace's branch lip into a calender, where it passes through two calender rollers, squeezing the molten glass into a solid sheet. Because the temperature in the center of the molten glass is high and the temperatures on the sides are low, a lateral temperature difference inevitably occurs. During the cooling process in the annealing lehr, the lateral temperature difference must be minimized to facilitate annealing. A significant temperature difference between the sides and the center of the glass sheet can have a detrimental impact on the final quality of the glass during annealing in the lehr.

[0046] Optionally, the edge fire combustion auxiliary device also includes a compressed air edge fire combustion auxiliary component, and the compressed air edge fire combustion auxiliary component includes a second gas distributor, and the air inlet of the second gas distributor is connected to the compressed air pipeline; the number of the air outlets of the second gas distributor is the same as the number of the burners, and the air outlet of the second gas distributor is connected to the corresponding burner through a second gas branch pipe, and the second gas branch pipe is provided with a second ball valve, and the second ball valve is electrically connected to the controller. By arranging multiple air outlets at intervals along the conveying direction of the glass sheet on the second gas uniform distributor, and each air outlet of the second gas uniform distributor is connected to a burner through a second gas branch pipe with a second ball valve, when a malfunction of the calender causes a large temperature difference between the lateral side and the middle of the glass sheet, the operator can flexibly adjust the opening of the second ball valve located at different positions along the conveying direction according to the actual temperature difference, that is, control the amount of compressed air delivered to the burner per unit time, adjust the combustion state of the burner, and thereby adjust the heat output by the burner to the lateral side of the glass sheet, perform heat compensation on the lateral side of the glass sheet so that the temperature of the lateral side of the glass sheet rises, and reduce the temperature difference between the lateral side of the glass sheet and the middle of the glass sheet to meet the requirements of high-quality annealing, ensuring that production does not need to be interrupted when a malfunction of the calender causes a large temperature difference between the lateral side and the middle of the glass sheet, thereby ensuring the continuity of production and avoiding large economic losses. A second gas distributor is also connected between multiple second gas branches of the compressed air edge fire combustion auxiliary component and the compressed air pipeline. The second gas distributor can evenly distribute the compressed air entering from the air inlet over the entire cross-section of the second gas distributor, thereby stabilizing the compressed air before entering each second gas branch, and ensuring that the compressed air delivered to the second gas branches located at different positions along the delivery direction is basically the same, ensuring that the burners located at different positions along the delivery direction stably output the same heat to the lateral side of the glass sheet, thereby ensuring that the temperature difference between the lateral side of the glass sheet and the middle of the glass sheet is reduced to meet the requirements of high-quality annealing.

[0047] Optionally, six first gas branch pipes 2 are provided. According to actual needs, the first ball valves 21 of one, two, three, four, five or six first gas branch pipes 2 of the natural gas edge fire combustion auxiliary assembly can be opened according to a set opening to meet different heat compensation requirements and have a wider range of applications.

[0048] In specific applications, the number of first gas branches 2 can be reasonably increased or decreased according to different heat compensation requirements. For example, in other embodiments, the natural gas edge fire combustion auxiliary component is provided with two, three, four, five or seven other numbers of first gas branches 2.

[0049] Optionally, six second gas delivery branches are provided. According to actual needs, the second ball valves of one, two, three, four, five, or six second gas delivery branches of the compressed air edge fire combustion auxiliary assembly can be opened to a set opening to meet different heat compensation requirements and have a wider range of applications.

[0050] In specific applications, the number of second gas branches can be reasonably increased or decreased according to different heat compensation requirements. For example, in other embodiments, the compressed air side fire combustion auxiliary component is provided with two, three, four, five or seven other numbers of second gas branches.

[0051] Optionally, the air inlet of the first gas distributor 1 is connected to the gas pipeline through the first air inlet pipeline 3. The first air inlet pipeline 3 is provided with a third ball valve 31, and the third ball valve 31 is used to control the on-off of the first air inlet pipeline 3. When there is no need to perform heat compensation on the lateral side of the glass sheet, the third ball valve 31 is closed to disconnect the first air inlet pipeline 3, ensuring that the gas in the gas pipeline will not be delivered to the first gas distributor 1, so that the edge fire combustion auxiliary device of this embodiment can be reliably and accurately switched to the closed state. It is also possible to control the opening of the third ball valve 31 when performing heat compensation on the lateral side of the glass sheet, thereby controlling the amount of gas delivered to the first gas distributor 1 per unit time, thereby adjusting the heat output by the burner to the lateral side of the glass sheet to meet different temperature compensation requirements.

[0052] Optionally, the air inlet of the second gas distributor is connected to the compressed air pipeline through the second air inlet pipeline, and a fourth ball valve is provided on the second air inlet pipeline, and the fourth ball valve is used to control the on-off of the second air inlet pipeline. When there is no need to perform heat compensation on the lateral side of the glass sheet, the fourth ball valve is closed to disconnect the second air inlet pipeline, ensuring that the compressed air in the compressed air pipeline will not be delivered to the second gas distributor, so that the edge fire combustion auxiliary device of this embodiment can be reliably and accurately switched to the closed state. It is also possible to control the opening of the fourth ball valve when performing heat compensation on the lateral side of the glass sheet, thereby controlling the amount of compressed air delivered to the second gas distributor per unit time, thereby adjusting the heat output by the burner to the lateral side of the glass sheet to meet different temperature compensation requirements.

[0053] Optionally, the edge-fire combustion auxiliary device further includes an installation cavity 41 disposed beneath the ground 4, with one end of the first air intake pipe 3 for connection to the gas pipe being concealed and embedded within the installation cavity 41, and one end of the second air intake pipe for connection to the compressed air pipe being concealed and embedded within the installation cavity 41. This arrangement allows both the gas pipe and the compressed air pipe to be routed below the ground 4, with both the end of the first air intake pipe 3 connected to the gas pipe and the end of the second air intake pipe connected to the compressed air pipe being concealed and embedded beneath the ground 4. This avoids occupying the space reserved for air ducts and water pipes used in other processes, thereby optimizing the layout space.

[0054] Optionally, the first gas distributor 1 is provided with a first detection interface 11, which is provided with a first pressure gauge 5; the second gas distributor is provided with a second detection interface, which is provided with a second pressure gauge. The first pressure gauge 5 and the second pressure gauge respectively display the pressure inside the first gas distributor 1 and the second gas distributor, so that operators can observe and detect whether there are any leaks in the first gas distributor 1 and the second gas distributor, and adjust the pressure ratio of the gas pipeline and the compressed air pipeline.

[0055] Optionally, the first detection interface 11 and the first pressure gauge 5 are connected via a first branch pipe 6, and a first shut-off valve 61 is provided on the first branch pipe 6. The first shut-off valve 61 is used to control the opening and closing of the first branch pipe 6. When the first pressure gauge 5 is damaged and is removed for repair or replacement, the first shut-off valve 61 can be closed to disconnect the first branch pipe 6, thereby effectively preventing the gas in the first gas distributor 1 from leaking to the outside through the first branch pipe 6 during the process of removing the first pressure gauge 5 for repair or replacement.

[0056] Optionally, the second detection interface and the second pressure gauge are connected via a second branch pipe, which is provided with a second shut-off valve for controlling the opening and closing of the second branch pipe. If the second pressure gauge is damaged and removed for repair or replacement, the second shut-off valve can be closed to disconnect the second branch pipe, effectively preventing compressed air in the gas distributor from leaking to the outside through the second branch pipe during the removal of the second pressure gauge for repair or replacement.

[0057] Optionally, a first check valve 22 is provided on the first gas branch pipe 2. The first check valve 22 can prevent the gas from flowing back or reversely from the burner through the first gas branch pipe 2 back into the first gas distributor 1, ensuring that the gas can only flow in one direction in the first gas branch pipe 2, thereby ensuring the safety and stability of the edge fire combustion auxiliary device of this embodiment.

[0058] Optionally, a second check valve is provided on the second gas branch pipe. The second check valve can prevent the compressed air from flowing back or reversely from the burner through the second gas branch pipe into the second gas distributor, ensuring that the compressed air can only flow in one direction in the second gas branch pipe, thereby ensuring the safety and stability of the edge fire combustion auxiliary device of this embodiment.

[0059] Specifically, the edge fire combustion auxiliary device also includes a conveying assembly for connecting the kiln and the annealing furnace. The conveying assembly is used to convey the glass sheet from the outlet of the kiln to the inlet of the annealing furnace. Two edge fire combustion auxiliary assemblies are arranged on opposite sides of the conveying assembly in the transverse direction. The glass sheet output from the kiln is automatically conveyed into the annealing furnace by the conveying assembly. During this process, the natural gas edge fire combustion auxiliary assembly and the compressed air edge fire combustion auxiliary assembly cooperate to compensate for the heat of the lateral heating of the glass sheet, so that the temperature difference between the lateral side of the glass sheet and the middle of the glass sheet, as well as the temperature difference between the lateral rear side of the glass sheet and the middle of the glass sheet, is restored to meet the requirements of high-quality annealing. More specifically, the conveying assembly is configured as a roller conveyor.

[0060] The operating principle of the edge fire combustion auxiliary device of this embodiment is as follows:

[0061] obtaining a first temperature difference between a lateral side and a middle portion of the glass sheet output from the furnace;

[0062] The first temperature difference is compared with the first standard temperature difference to obtain a first compensation adjustment value. The operator adjusts the opening of the first ball valve 21 of the natural gas edge fire combustion auxiliary component according to the first compensation adjustment value, so that the burner performs corresponding heat compensation on the lateral side heating of the glass sheet, ensuring that the temperature difference between the lateral side and the middle of the glass sheet entering the annealing furnace meets the requirements of high-quality annealing.

[0063] Specifically, the first standard temperature difference refers to the temperature difference between the front side and the middle of the glass sheet in the horizontal direction that meets the annealing requirements.

[0064] It should be noted that the first temperature sensor and the second temperature sensor respectively detect the lateral side temperature and the middle temperature of the glass sheet output from the kiln, and obtain the first temperature value and the second temperature value respectively, and the first temperature difference is calculated based on the first temperature value and the second temperature value.

[0065] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
