[0011] Among them, if the pressure value detected by the pressure sensor is less than the pressure regulation threshold, the controller controls the pressure regulating valve to increase the pressure of the gas transported in the delivery pipe; if the pressure value detected by the pressure sensor is greater than the pressure regulation threshold, the controller controls the pressure regulating valve to reduce the pressure of the gas transported in the delivery pipe.

[0012] Optionally, the pressure sensor is located at one end of the delivery pipe close to the second air inlet, so that the pressure sensor can detect the pressure of the gas delivered in the delivery pipe and detect the pressure in the second gas storage tank, and the pressure regulating valve is located at one end of the delivery pipe close to the first air outlet.

[0027] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0028] In this disclosure, unless otherwise indicated, directional terms such as "upper," "lower," "left," and "right" are generally defined relative to the drawing plane of the accompanying drawings, and "inner" and "outer" refer to the inside and outside of the relevant component. Furthermore, the terms "first," "second," and the like are used solely for purposes of distinction and are not to be construed as indicating or implying relative importance.

[0029] It should also be noted that, in the description of this disclosure, unless otherwise expressly specified or limited, the terms "disposed" and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this disclosure based on specific circumstances.

[0030] like Figure 1 and Figure 2 As shown, the present disclosure provides a sulfur dioxide gas supply system, including a first gas storage tank 1, a heating component, a delivery pipe 8, a second gas storage tank 10, a pressure regulating component and a flow regulating component.

[0031] The first gas storage tank 1 has a first gas inlet and a first gas outlet. The first gas inlet is used to fill with sulfur dioxide gas. The heating component is connected to the first gas storage tank 1 and is used to heat the gas in the first gas storage tank 1.

[0032] The second gas storage tank 10 has a second air inlet and a second air outlet. The air inlet end of the flow regulating component is connected to the second air outlet, and the air outlet end of the flow regulating component is used to connect to the jetting component.

[0033] The two ends of the delivery pipe 8 are connected to the first air outlet and the second air inlet respectively. The pressure regulating component is connected to the delivery pipe 8. The pressure regulating component is used to adjust the pressure of the gas transported in the delivery pipe 8 to keep the air pressure in the second gas storage tank 10 stable.

[0034] Sulfur dioxide gas can enter the first gas storage tank 1 through the first gas inlet and can be temporarily stored in the first gas storage tank 1 to achieve temperature and pressure regulation of the sulfur dioxide gas. The heating component can heat the sulfur dioxide gas in the first gas storage tank 1 so that the sulfur dioxide gas can be maintained at a stable constant temperature. Therefore, when the sulfur dioxide gas is transported to contact the glass, it will not cause quality fluctuations or stress changes in the glass.

[0035] Among them, the contact between sulfur dioxide gas and glass is mainly concentrated in front of the annealing furnace. At this time, the temperature of the glass can reach 1288°C. If the low-temperature sulfur dioxide gas comes into contact with the glass, it will cause quality fluctuations and stress changes in the glass.

[0036] It should be noted that the heating component is mainly used in scenarios where the external ambient temperature is low or the temperature difference between day and night is large. When the external ambient temperature is high and the temperature difference between day and night is small, the heating component can be turned off.

[0037] When the ambient temperature is high, the sulfur dioxide gas maintains a relatively high temperature, and the high-temperature sulfur dioxide gas contacts the glass, having little impact on glass production. However, when the ambient temperature is low, the sulfur dioxide storage tank is generally located in the outside environment, and the sulfur dioxide temperature is relatively low. If it is directly transported to the glass surface, it will cause fluctuations in glass quality and stress changes, affecting the glass yield rate. At the same time, the low-temperature sulfur dioxide gas is not easy to form a sulfur film on the glass surface, affecting the protective effect of the glass. In addition, when the low-temperature sulfur dioxide gas is transported into the workshop, it will also affect the overall temperature inside the workshop, which will also affect glass production.

[0038] The second gas tank 10 is used to store sulfur dioxide gas that needs to come into contact with the glass. The sulfur dioxide gas in the second gas tank 10 has its temperature and pressure adjusted to the desired values ​​and can be directly delivered to the injection unit via a flow control assembly for spraying onto the glass surface. The flow control assembly can adjust the flow rate of the sulfur dioxide gas to prevent excessive or insufficient sulfur dioxide gas from being sprayed.

[0039] The delivery pipe 8 is used to guide the sulfur dioxide gas in the first gas tank 1 to the second gas tank 10. The pressure regulating assembly can adjust the pressure of the sulfur dioxide gas flowing from the first gas tank 1 through the delivery pipe 8 to the second gas tank 10, so that the pressure in the second gas tank 10 remains constant, and the contact effect between the sulfur dioxide gas and the glass surface will not be affected by changes in the pressure at the gas source of the sulfur dioxide gas.

[0040] It is understandable that in the prior art, when the pressure at the source of sulfur dioxide gas changes, the conveying force of the sulfur dioxide gas will fluctuate, and thus the degree of contact between the sulfur dioxide gas and the glass surface will also fluctuate, thereby affecting the thickness of the sulfur film formed by the sulfur dioxide gas on the surface, resulting in uneven thickness of the sulfur film, which may affect the protective effect of the glass.

[0041] In the above technical solution, the first and second gas tanks 1 and 10 facilitate regulating the temperature and pressure of the sulfur dioxide gas. The pressure regulating assembly and the heating assembly enable the temperature and pressure of the sulfur dioxide gas in the second gas tank 10 to reach the desired values, thereby maintaining the temperature and pressure of the sulfur dioxide gas in contact with the glass surface at a stable state. This improves the stability of the formed sulfur film, thereby increasing the consistency of the degree of protection provided to the glass and improving the yield rate of manufactured glass. The pressure regulating assembly facilitates adjusting the pressure of the sulfur dioxide gas delivered from the first gas tank 1 to the second gas tank 10, while the heating assembly facilitates heating of the sulfur dioxide gas in the second gas tank 10, allowing for centralized heating of the sulfur dioxide gas. This protects the sulfur dioxide gas from the low ambient temperature and the large temperature difference between day and night, thereby preventing fluctuations in glass quality and stress changes, significantly reducing defects during glass manufacturing, and improving the yield rate of glass.

[0042] Optionally, in one embodiment of the present disclosure, the pressure regulating assembly includes a pressure sensor 9, a pressure regulating valve 7 and a controller 6, the pressure sensor 9 is connected to the delivery pipe 8, the pressure sensor 9 is used to detect the pressure of the gas transported in the delivery pipe 8, the pressure regulating valve 7 is connected to the delivery pipe 8, the pressure regulating valve 7 can regulate the pressure of the gas transported in the delivery pipe 8, and the pressure sensor 9 and the pressure regulating valve 7 are both electrically connected to the controller 6.

[0043] In this embodiment, the pressure sensor 9 can detect the pressure of the gas and transmit the detected pressure data to the controller 6. The controller 6 controls the pressure regulating valve 7 to adjust the pressure of the sulfur dioxide gas flowing out of the first gas outlet of the first gas storage tank 1 according to the detected pressure data, so that the pressure of the sulfur dioxide gas entering the second gas storage tank 10 reaches the required value.

[0044] Specifically, the pressure regulating valve 7 is a prior art device that can adjust the gas pressure. The pressure sensor 9 is connected to the outer wall of the delivery pipe 8, and the detection end of the pressure sensor 9 extends into the delivery pipe 8 to detect the pressure of the sulfur dioxide gas.

[0045] In the technical solution of this embodiment, the pressure of the sulfur dioxide gas is detected by the provided pressure sensor 9, and the pressure regulating valve 7 is controlled by the controller 6, so that the pressure of the sulfur dioxide gas can be automatically adjusted. The operator only needs to set the adjustment parameters, which is easy to operate.

[0046] Optionally, in one embodiment of the present disclosure, the controller 6 can control the pressure regulating valve 7 according to the pressure value detected by the pressure sensor 9, and the controller 6 can set a pressure regulation threshold, which is 0.3-0.4 MPa;

[0047] Among them, if the pressure value detected by the pressure sensor 9 is less than the pressure regulation threshold, the controller 6 controls the pressure regulating valve 7 to increase the pressure of the gas transported in the delivery pipe 8; if the pressure value detected by the pressure sensor 9 is greater than the pressure regulation threshold, the controller 6 controls the pressure regulating valve 7 to reduce the pressure of the gas transported in the delivery pipe 8.

[0048] In this embodiment, the specific value of the pressure adjustment threshold can be set according to actual needs. When the pressure adjustment threshold is 0.3-0.4 MPa, the sulfur film formed by the sulfur dioxide gas on the glass surface has a uniform thickness. It should be noted that in the summer, when the temperature of the sulfur dioxide gas is higher, the pressure adjustment threshold is relatively high, which can ensure the discharge of the sulfur dioxide gas.

[0049] Optionally, in one embodiment of the present disclosure, the pressure sensor 9 is located at one end of the delivery pipe 8 near the second air inlet, so that the pressure sensor 9 can detect the pressure of the gas transported in the delivery pipe 8, and detect the pressure in the second gas storage tank 10, and the pressure regulating valve 7 is located at one end of the delivery pipe 8 near the first air outlet.

[0050] In this embodiment, by positioning the pressure sensor 9 at the end of the delivery pipe 8 near the second air inlet, the pressure of the gas delivered within the delivery pipe 8 and the pressure of the gas within the second gas tank 10 can be simultaneously detected, thereby enabling better regulation of the gas pressure within the second gas tank 10. Furthermore, positioning the pressure sensor 9 at the end of the delivery pipe 8 near the second air inlet allows detection of the pressure of the sulfur dioxide gas about to enter the second gas tank 10, thereby ensuring that the gas pressure within the second gas tank 10 is stable and does not fluctuate significantly.

[0051] In this embodiment, the pressure regulating valve 7 is located at one end of the delivery pipe 8 close to the first gas outlet, so that the pressure of the sulfur dioxide gas coming out of the first gas outlet of the first gas storage tank 1 can be adjusted in time, so that the sulfur dioxide gas can maintain a stable pressure state in the delivery pipe 8 and then enter the second gas storage tank 10.

[0052] Optionally, in one embodiment of the present disclosure, the heating component includes a heating element 3, a thermocouple 5 and a temperature controller 4, the heating element 3, the thermocouple 5 and the temperature controller 4 are all connected to the first gas storage tank 1, the heating element 3 is used to heat the gas in the first gas storage tank 1, the thermocouple 5 is used to detect the temperature of the gas in the first gas storage tank 1, the heating element 3 and the thermocouple 5 are both electrically connected to the temperature controller 4, and the temperature controller 4 can control the power of the heating element 3 according to the temperature detected by the thermocouple 5.

[0053] In this embodiment, the heating element 3 can generate heat, and the first gas tank 1 can conduct heat, allowing the heat to be transferred into the first gas tank 1, thereby heating the gas in the first gas tank 1. The thermocouple 5 can detect the temperature of the sulfur dioxide gas in the first gas tank 1. The detected temperature value can be transmitted to the temperature controller 4. The temperature controller 4 can control the power of the heating element 3, thereby controlling the temperature of the sulfur dioxide gas in the first gas tank 1. In this way, the sulfur dioxide gas in the first gas tank 1 reaches a suitable temperature, and the temperature of the sulfur dioxide gas sprayed onto the glass is not affected by changes in external temperature.

[0054] It is understood that a temperature threshold can be set on the temperature controller 4. When the temperature value detected by the thermocouple 5 is lower than the temperature threshold, the temperature controller 4 controls the heating element 3 to increase the power, thereby increasing the heating effect on the sulfur dioxide gas in the first gas storage tank 1. When the temperature value detected by the thermocouple 5 is higher than the temperature threshold, the temperature controller 4 controls the heating element 3 to decrease the power, thereby reducing the heating effect on the sulfur dioxide gas in the first gas storage tank 1. Specifically, the temperature threshold can be 20-24°C, and can be set according to actual needs.

[0055] Optionally, in one embodiment of the present disclosure, the heating element 3 is a heating tube, which is spiral-shaped and surrounds the outer wall of the first gas storage tank 1 .

[0056] In this embodiment, the heating tube utilizes resistance heating, and the heating temperature can be varied by adjusting the resistance of the heating tube. By wrapping the heating tube around the outer wall of the first gas tank 1, the first gas tank 1 can be uniformly heated, ensuring that the sulfur dioxide gas within the first gas tank 1 is evenly heated.

[0057] Alternatively, in another embodiment of the present disclosure, the heating element 3 may be a heating plate connected to the inner wall of the first gas storage tank 1, and may directly heat the sulfur dioxide gas in the first gas storage tank 1. However, sulfur dioxide gas is corrosive and may easily corrode the heating plate.

[0058] Optionally, in one embodiment of the present disclosure, the flow regulating assembly includes a flow regulating valve 12, a connecting hose 13 and a flow meter 14, the flow regulating valve 12 is connected to the second air outlet, the connecting hose 13 is connected to the flow regulating valve 12, the end of the connecting hose 13 away from the flow regulating valve 12 is connected to the inlet end of the flow meter 14, and the outlet end of the flow meter 14 is used to connect to the jet component.

[0059] In this embodiment, flow control valve 12 is used to adjust the flow rate of sulfur dioxide gas delivered to flow meter 14, thereby adjusting the flow rate of sulfur dioxide gas sprayed onto the glass to prevent excessive or insufficient sulfur dioxide gas from being sprayed. Flow meter 14 is used to display the flow rate of the delivered sulfur dioxide gas, facilitating flow control by flow control valve 12. Specifically, flow meter 14 can be a rotameter.

[0060] Specifically, in this embodiment, the flow regulating valve 12 is a needle valve, which can avoid being corroded by sulfur dioxide gas and can increase the service life of the equipment. The connecting hose 13 is a fluororubber hose, which can resist the corrosion of sulfur dioxide gas.

[0061] Optionally, in one embodiment of the present disclosure, there are multiple flow regulating components;

[0062] The flow meters 14 in each flow regulating assembly are arranged in parallel, the number of the second air outlets is multiple, and the flow regulating valves 12 in each flow regulating assembly are respectively connected to the corresponding second air outlets.

[0063] Specifically, in this embodiment, there are six flow regulating assemblies, corresponding to six second air outlets. A flow regulating valve 12 is connected to each second air outlet, enabling flow regulation at each outlet. Four of the six flow regulating assemblies are in regular use, while the remaining two are standby. By arranging multiple flow regulating assemblies in parallel, operators can operate them simultaneously, reducing their workload. Multiple flow regulating assemblies can also adjust the amount of sulfur dioxide gas sprayed to different glass surfaces or at different glass locations, providing greater flexibility.

[0064] Optionally, in one embodiment of the present disclosure, the sulfur dioxide gas supply system further includes a fixing frame 11, a mounting plate 15 is formed on the fixing frame 11, the flow meter 14 is connected to the mounting plate 15, and the second gas storage tank 10 is connected to the fixing frame 11, and the second gas storage tank 10 is located below the mounting plate 15.

[0065] In this embodiment, the mounting bracket 11 is used to support and secure the second gas tank 10, and the mounting plate 15 is used to support and secure the flow meter 14. The mounting plate 15 facilitates the parallel placement of multiple flow meters 14, facilitating unified operation and adjustment by the operator. Furthermore, positioning the flow meter 14 above the second gas tank 10 facilitates the upward entry of sulfur dioxide gas into the flow meter 14, enabling stable delivery and facilitating the uniform and stable entry of sulfur dioxide gas into the flow meter 14, reducing resistance to entry into the flow meter 14 and improving the detection accuracy of the flow meter 14.

[0066] Specifically, there are two mounting plates 15 , which are arranged one above the other. The flow meter 14 is located between the two mounting plates 15 , thereby improving the fixing effect on the flow meter 14 .

[0067] Optionally, in one embodiment of the present disclosure, the sulfur dioxide gas supply system further includes a thermal insulation sleeve 16 , which is sleeved on the first gas storage tank 1 , the heating assembly, the delivery pipe 8 and the second gas storage tank 10 .

[0068] In this embodiment, the insulation jacket 16 can insulate the first gas tank 1, the heating assembly, the delivery pipe 8, and the second gas tank 10, thereby preventing heat loss from the heated sulfur dioxide gas and stabilizing the temperature of the sulfur dioxide gas. Specifically, the insulation jacket 16 can be filled with thermal insulation cotton to ensure a good thermal insulation effect.

[0069] Optionally, in one embodiment of the present disclosure, the sulfur dioxide gas supply system further comprises an air inlet pipe 2, which is connected to the first air inlet and facilitates the entry of sulfur dioxide gas into the first gas storage tank 1. An insulation sleeve 16 is also provided on the air inlet pipe 2 to provide thermal insulation.

[0070] When the present sulfur dioxide gas supply system is actually used, the operator sets the pressure adjustment threshold and the temperature threshold. At the same time, the operator operates the flow control valve 12 according to actual production needs to adjust the flow of sulfur dioxide gas delivered to the glass. After the flow is adjusted, the pressure of the sulfur dioxide gas in the second gas storage tank 10 is automatically controlled by the controller 6, and the temperature of the sulfur dioxide gas in the first gas storage tank 1 is controlled by the temperature controller 4, thereby achieving automatic control. The operator only needs to conduct regular inspections.

However, the present disclosure is not limited to the specific details of the above embodiments.

In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0073] In addition, the various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
