Description

Technical Field

[0001] This utility model relates to the technical field of float glass equipment, and in particular to a float glass tank wall air pressure and temperature control system. Background Technology

[0002] In the float glass production process, the melting furnace is the core equipment, and its operating environment directly affects the quality of the glass products. As an important auxiliary system of the melting furnace, the main function of the tank wall ventilation system is to blow an appropriate amount of cold air onto the surface of the furnace tank wall, forming a cooling air film on the surface of the tank wall bricks. This air film can effectively reduce the temperature of the tank wall brick surface, and by adjusting the air volume at different locations, the temperature of the tank wall bricks can be maintained within a reasonable range, thereby achieving the goals of energy saving, extending furnace life, and stabilizing the flow of molten glass. When the external ambient temperature changes, the system's air pressure fluctuates accordingly. However, traditional structures often rely on manual adjustment of the air pressure, which is difficult to adjust in a timely manner, leading to an imbalance in the cooling effect. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies where traditional structures rely on manual adjustment of air pressure, which makes timely adjustment difficult and leads to an imbalance in cooling effect. This invention provides a float glass tank wall air pressure and temperature control system.

[0004] In a first aspect, the present invention provides a float glass pool wall air pressure and temperature control system, including an air inlet pipeline, one end of which is connected to a fan and the other end is connected to the pool wall, and a cloud controller is connected to the fan.

[0005] The cloud controller is connected to a first temperature thermocouple and a second temperature thermocouple. The first temperature thermocouple is connected to the air inlet duct, and the second temperature thermocouple is connected to the pool wall.

[0006] The first temperature thermocouple is used to collect the temperature value of the air inlet duct;

[0007] The second temperature thermocouple is used to collect the temperature value of the pool wall;

[0008] The cloud controller is used to generate an adjustment command based on the difference between the temperature value of the air inlet duct and the temperature value of the pool wall. The adjustment command is used to adjust the operating frequency of the fan.

[0009] This invention provides a float glass tank wall air pressure and temperature control system. By installing a first temperature thermocouple and a second temperature thermocouple on the air inlet pipeline and the tank wall respectively, the system can acquire real-time temperature changes in the air inlet pipeline and the tank wall. Both the first and second temperature thermocouples are connected to a cloud controller. The cloud controller automatically generates adjustment commands based on the temperature difference between the two thermocouples, thereby adjusting the operating frequency of the fan and ensuring that the tank wall temperature is within a reasonable range. Compared to the traditional method of manual adjustment, this application uses a cloud controller to compare the temperature in the air inlet pipeline with the temperature of the tank wall to generate adjustment commands, which in turn adjust the operating frequency of the fan. The response time is faster than manual adjustment, reducing the possibility of cooling effect imbalance.

[0010] Preferably, the air inlet pipeline includes a main air duct, one end of which is connected to the fan and the other end is connected to a branch air duct, and the end of the branch air duct away from the main air duct is connected to the pool wall.

[0011] Preferably, a control cabinet is provided between the wind turbine and the cloud controller, and the control cabinet is configured so that the cloud controller can control the wind turbine through the control cabinet.

[0012] Preferably, the control system further includes a wind pressure transmitter connected to the main air duct, which is used to collect the wind pressure value in the main air duct.

[0013] By installing a wind pressure transmitter on the main air duct, the wind pressure value in the main air duct can be collected in real time and continuously, avoiding data lag and errors caused by relying on manual detection, thereby ensuring the accuracy and reliability of the collected results.

[0014] Preferably, the cloud controller includes a receiving module, which is used to receive the temperature value of the pool wall, the temperature value of the air inlet duct, and the air pressure value in the main air duct;

[0015] The cloud controller also includes a processing module, which is used to comprehensively analyze the temperature value of the pool wall, the air pressure value of the main air duct, and the temperature value of the air inlet duct, and generate corresponding adjustment instructions.

[0016] The cloud controller also includes a sending module, which is used to send the adjustment command to the control cabinet, and the control cabinet adjusts the operating frequency of the fan according to the adjustment command.

[0017] Preferably, the processing module is equipped with a proportional control algorithm, an integral control algorithm, and a derivative control algorithm.

[0018] Preferably, the branch duct is equipped with a branch duct controller, which is used to control the air volume in the branch duct.

[0019] By installing branch duct controllers on the branch ducts, the air volume of each branch duct can be adjusted individually according to the cooling needs of the pool walls in different areas, achieving precise control of local air volume and avoiding situations where the total air volume adjustment cannot meet the local cooling requirements.

[0020] Preferably, the branch duct controller includes a fan blade structure, the top of which is provided with a rotating shaft. One end of the rotating shaft is connected to the fan blade structure, and the other end is connected to a cylinder structure. The cylinder structure is used to control the rotation of the fan blade structure.

[0021] The air volume in the branch duct is controlled by changing the rotation angle of the fan blade structure. The cylinder structure can precisely drive the rotating shaft to rotate, thereby achieving continuous and controllable adjustment of the air volume in each branch duct and improving the adjustment accuracy.

[0022] Preferably, the cylinder structure includes a cylinder body, a positioner is provided on one side of the cylinder body, the positioner is used to control the valve position of the cylinder body, and a fixed bracket is provided on the side of the positioner away from the cylinder body.

[0023] By fixing the valve position with a positioner, the action of adjusting the air volume can be repeated each time, avoiding air volume drift over time and enhancing the stability and uniformity of the cooling of the pool wall.
