Description

A compressed air valve assembly, an auxiliary combustion nozzle, and a sidefire combustion auxiliary device. Technical Field

[0001] This utility model relates to the field of glass production equipment technology, specifically to a compressed air valve group, an auxiliary combustion nozzle, and a side-fire combustion auxiliary device. Background Technology

[0002] As a crucial component of photovoltaic modules, the quality of photovoltaic glass directly impacts the module's photoelectric conversion efficiency and lifespan. The production process of photovoltaic glass typically includes two main stages: raw material production and further processing. Raw material production primarily involves steps such as material preparation, melting, rolling, annealing, and cutting to obtain unprocessed photovoltaic glass sheets. Subsequent further processing involves edge grinding, tempering, and coating on the raw sheets to meet the requirements of module encapsulation.

[0003] "Edge heating" refers to heating the edges of glass sheets with a flame to relieve stress, trim edges, or seal edges. In edge heating, the mixture of compressed air and gas affects the "hardness" of the flame. High-pressure gas makes the flame harder and more concentrated, resulting in higher flame temperature and stronger penetration; conversely, a smaller volume of compressed air results in a "softer" flame, with a wider heating area but lower temperature, suitable for slow heating.

[0004] In addition, in the edge-burning process, compressed air is used to adjust the flow rate of the compressed air to achieve directional adjustment of the flame, which can simultaneously improve combustion efficiency and reduce gas consumption.

[0005] In the existing technology, due to the difficulty in controlling the output of compressed air, the pressure and flow of compressed air are unstable. This can easily lead to an excessively "hard" flame, causing excessive local temperature differences at the glass edge, forming new thermal stress, or even causing edge breakage; or an excessively "soft" flame, resulting in insufficient heating and inability to effectively release stress. In addition, the instability of compressed air leads to uneven heating, which can cause optical performance problems in the glass or deformation during subsequent tempering.

[0006] In the edge-burning process, the instability of compressed gas can lead to incomplete combustion, resulting in safety risks such as carbon deposition and flame absorption. Summary of the Invention

[0007] In view of this, the present invention provides a compressed air valve assembly, an auxiliary combustion nozzle, and an auxiliary device for edge-fire combustion to solve the problems of instability in the output of compressed air in the edge-fire process of the prior art, which leads to the easy occurrence of new stress or incomplete stress elimination during stress removal, as well as poor optical performance or deformation of the produced glass products.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0030] Referring to Figure 1, in a first aspect, this utility model provides a compressed air valve assembly for a side-fire process in a photovoltaic glass kiln, comprising: a first gas supply pipe, a first valve body 11, a regulating valve 16, a monitoring element, and a controller; a first end of the first gas supply pipe is connected to a compressed gas source, and a second end of the first gas supply pipe is connected to a side-fire combustion device, with compressed gas flowing from the first end to the second end; along the flow direction of the compressed gas, the first gas supply pipe 1 is sequentially provided with the first valve body 11, the regulating valve 16, and the monitoring element; the first valve body 11 is disposed near the first end, and the monitoring element is disposed near the second end; both the regulating valve 16 and the monitoring element are communicatively connected to the controller, the monitoring element being adapted to monitor the dynamic parameters of the compressed gas in the first gas supply pipe 1 and provide real-time feedback to the controller, the controller receiving the dynamic parameters and being adapted to control the opening degree of the regulating valve 16.

[0031] Specifically, by sequentially installing a first valve body 11, a regulating valve 16, and a monitoring element on the first gas supply pipe, with both the regulating valve 16 and the monitoring element communicatively connected to the controller, the controller can dynamically adjust the opening of the regulating valve 16 based on the real-time dynamic parameters of the compressed gas collected by the monitoring element, thereby achieving precise control of the compressed gas flow or pressure. By setting up a closed-loop control structure with the regulating valve 16 and the real-time monitoring element, dynamic and precise adjustment of the compressed air supply status can be achieved, improving the stability of the edge-fire combustion process. The controller can respond in real-time based on the parameters fed back by the monitoring element, reducing control lag and improving system response efficiency. By monitoring the compressed gas status in real time and adjusting it rapidly, combustion abnormalities caused by excessive or insufficient gas supply can be avoided, ensuring the continuity and safety of the kiln edge-fire process, thereby improving the production quality and efficiency of glass products.

[0032] In a first aspect of this utility model, the monitoring element is a pressure detection element 12, and the dynamic parameter is a gas pressure parameter.

[0033] In a first aspect of this utility model, the monitoring element is a flow detection element, and the dynamic parameter is a flow parameter.

[0034] Understandably, when the monitoring element is a pressure monitoring element, the dynamic parameter is the air pressure parameter. Specifically, the monitoring element can be a pressure sensor. After detecting the pressure parameter in the first air supply pipe 1, the pressure sensor feeds it back to the controller in real time. The controller, based on the received pressure parameter, compares it with the set threshold parameter and controls the regulating valve 16. That is, when the pressure parameter is less than the first threshold, the controller controls the opening of the regulating valve 16 to increase; when the pressure parameter is greater than the second threshold, the controller controls the opening of the regulating valve 16 to decrease; when the pressure parameter is greater than the first threshold but less than the second threshold, the controller controls the opening to remain unchanged. This ensures that the compressed air is output at a constant pressure, avoiding excessive compressed air pressure leading to excessive local temperature differences at the glass edge, forming new thermal stress or even causing edge breakage; or insufficient compressed air pressure preventing the glass from releasing stress. Furthermore, a stable compressed air pressure output avoids uneven heating and incomplete combustion caused by the instability of compressed air, thus improving the production quality of glass products.

[0035] Similarly, the flow detection element can be called a flow sensor. The setting of the flow detection element can ensure that the compressed gas is output at a stable flow rate, thus ensuring the stability of the compressed gas output and improving the production quality of glass products.

[0036] In a first aspect of this utility model, the first gas supply pipe body is further provided with a second valve body 15 and a third valve body 14, the second valve body 15 being disposed between the monitoring element and the regulating valve 16, and the third valve body 14 being disposed between the first valve body 11 and the regulating valve 16.

[0037] It also includes a second gas supply pipe 2, which is arranged in parallel with the first gas supply pipe 1. The second gas supply pipe 2 has a third end and a fourth end. Along the flow direction of the compressed air, the third end is located at the rear end of the second valve body 15, and the fourth end is located at the rear end of the third valve body 14. The second gas supply pipe 2 is also provided with a fourth valve body 21.

[0038] Specifically, by setting up a second air supply pipeline 2, a dual-channel air supply system is achieved, improving system reliability. When the regulating valve 16 malfunctions, the second output pipeline ensures the normal delivery of compressed air, thereby guaranteeing the normal operation of the system and preventing production line shutdowns due to component repairs. This reduces maintenance costs and improves production efficiency.

[0039] In a first aspect embodiment of the present invention, the first valve body 11, the second valve body 15, the third valve body 14 and the fourth valve body 21 are all manual ball valves;

[0040] In the first gas delivery state, the first valve body 11, the second valve body 15 and the third valve body 14 are open, the fourth valve body 21 is closed, and the monitoring element is adapted to monitor the dynamic parameters of the compressed air in the first gas delivery pipeline 1.

[0041] In the second gas delivery state, the first valve body 11 and the fourth valve body 21 are open, the second valve body 15 and the third valve body 14 are closed, and the monitoring element is adapted to monitor the dynamic parameters of the compressed air in the second gas delivery pipeline 2.

[0042] In a first aspect of this utility model, the first valve body 11, the second valve body 15, and the third valve body 14 are all electric valves and are all communicatively connected to the controller, and the fourth valve body 21 is a manual ball valve.

[0043] Specifically, the first valve body 11, the second valve body 15, and the third valve body 14 are all electric valves, which are started and closed by a controller, thereby improving automation capabilities and reducing the difficulty of operation. The fourth ball valve is set as a manual ball valve to ensure that the production line can operate normally in abnormal situations such as partial power outages, thereby improving the reliability and safety of the system.

[0044] In a first aspect of the present invention, the compressed air valve assembly further includes a mounting bracket 3, the upper and middle parts of which are respectively connected to the outer periphery of the first air supply pipe 1 and the second air supply pipe 2, and the lower end of the mounting bracket 3 is fixedly connected to the bottom surface.

[0045] Specifically, the mounting bracket 3 provides installation support and increases maintenance space by suspending the first gas pipeline 1 and the second gas pipeline 2 in the air.

[0046] Secondly, this utility model also provides an auxiliary combustion spray gun for use in the side fire combustion of a photovoltaic glass kiln, comprising a spray gun body, wherein the air inlet end of the spray gun body is connected to the compressed air valve group.

[0047] Thirdly, this utility model also provides a side-fire combustion auxiliary device, including the auxiliary combustion spray gun.

[0048] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
