Abstract
Description
Technical Field

[0002] Glass melting furnace refers to the thermal equipment used to melt glass batch materials in glass manufacturing. The powder prepared according to the glass composition and the added clinker (cullet) are melted and clarified at high temperature in the kiln to form glass liquid that meets the molding requirements. After the glass liquid is output from the melting furnace, it is cooled and pressed by the calendering equipment to form a glass plate output. The photovoltaic glass melting furnace includes components such as the horizontal passage and the branch passage. The horizontal passage of the glass melting furnace connects the melting furnace and the branch passage. After the formation of silicate, the formation, clarification and homogenization of the glass liquid are completed in the melting furnace, the qualified glass liquid is transported to the horizontal passage and the branch passage for cooling through the neck or the flow hole.

The two conveying pipes 2 are both equipped with wind bags 4, and the inner diameter of the wind bags 4 is larger than the inner diameter of the conveying pipes 2. The wind bags 4 can gather a certain amount of air volume, and the two wind bags 4 are equipped with multiple horizontal passage cooling pipes 5 and multiple branch passage cooling pipes 6. The horizontal passage cooling pipes 5 and the branch passage cooling pipes 6 are both equipped with wind nozzles 7, and the wind nozzles 7 blow the cold air in the wind bags 4 to the horizontal passage and the bottom of the branch passage pool to achieve the purpose of cooling. The connection of the multiple wind nozzles 7 is equipped with regulating valves 8, and the regulating valves 8 can adjust the valve opening, so as to control To control the air volume flowing inside, multiple temperature sensors 9 are installed on the bottom of the horizontal passage and the branch passage, each temperature sensor 9 is located directly above a wind nozzle 7, and the photovoltaic glass melting furnace horizontal branch passage bottom cooling system also includes a controller, which can be an MCU controller. Multiple regulating valves 8 and multiple temperature sensors 9 are electrically connected to the controller. When the temperature sensor 9 detects that the temperature at the corresponding position is higher, it will transmit a signal to the controller. The controller will send a corresponding signal according to the received signal (that is, the temperature condition at the temperature sensor 9), so that the regulating valve 8 adjusts its valve opening, and then the wind nozzle 7 blows different amounts of cold air to the area. In this way, the temperature of each area of the horizontal passage and the branch passage bottom can be accurately controlled to avoid large temperature differences and further reduce the generation of bubbles in the photovoltaic glass openings.
[0029] Example 2
[0030] like Figure 7As shown, the regulating valve 8 includes a valve body 81, and a valve core (not shown in the figure) is arranged inside the valve body 81. By adjusting the rotation angle of the valve core, the air volume passing through the valve body 81 can be adjusted. The rotating shaft of the valve core extends to the outside of the valve body 81 and is fixed with a worm gear 82. A motor 83 is installed on the valve body 81, and the motor 83 is electrically connected to the controller. A worm 84 is installed on the motor 83, and the worm 84 is meshed with the worm gear 82.

[0031] Example 3
[0032] like Figure 6 As shown, the height of one end of the branch channel cooling pipe 6 connected to the wind bag 4 is higher than half the height of the wind bag 4, which can prevent the water generated in the wind bag 4 from entering the branch channel cooling pipe 6, thereby preventing the water from being sprayed onto the bottom of the branch channel pool through the branch channel cooling pipe 6.
[0033] Example 4
[0034] like Figure 2 , 5As shown, a water collecting component is provided below the two wind bags 4, and the water collecting component is used to collect the water condensed in the wind bag 4 and discharge the collected water. Because the air in the wind bag 4 is lower in temperature than the outside, the moisture in the air will condense in the wind bag 4. If the moisture is not removed in time, the volume of the wind bag 4 will be reduced. At the same time, the moisture will be sprayed to the bottom of the horizontal passage and the branch passage along the wind nozzle 7, increasing the uncertainty of cooling. The water collecting component includes a water collecting box 10, on which two water inlet pipes 11 are installed, and the two water inlet pipes 11 are respectively connected to the corresponding air bags 4, and the two water inlet pipes 11 are both installed with a first solenoid valve 12, and a water outlet pipe 13 is installed at the bottom of the water collecting box 10, and the water outlet pipe 13 is installed with a second solenoid valve 14, the first solenoid valve 12 and the second solenoid valve 14 will not be opened at the same time, when one of them is opened, the other is in a closed state, the first solenoid valve 12 and the second solenoid valve 14 are both electrically connected to the controller, and the top and side of the water collecting box 10 are respectively installed with a first liquid level sensor 15 and a second liquid level sensor 16, and the first liquid level sensor 15 and the second liquid level sensor 16 are both electrically connected to the controller Connection, in the initial state, the first solenoid valve 12 is in the open state, and the second solenoid valve 14 is in the closed state. When water appears in the wind bag 4, the water will enter the water collecting tank 10 through the water inlet pipe 11. After the water level in the water collecting tank 10 reaches a certain height and contacts with the first liquid level sensor 15, the first liquid level sensor 15 will transmit a signal to the controller, and the controller will process the signal and send a signal to close the first solenoid valve 12 and open the second solenoid valve 14, so as to achieve the purpose of drainage. When the water level in the water collecting tank 10 is lower than the second liquid level sensor 16, the second liquid level sensor 16 will transmit a signal to the controller, and the controller will send a signal to close the second solenoid valve 14 and open the first solenoid valve 12, so that the water in the wind bag 4 can enter the water collecting tank 10 again.
[0035] Furthermore, a gas one-way valve 17 is installed on the top of the water collecting tank 10, and air can enter the water collecting tank 10 through the gas one-way valve 17. During the drainage process of the water collecting tank 10, the internal air pressure will gradually decrease. In order to ensure smooth drainage, the outside air will enter the water collecting tank 10 through the gas one-way valve 17 to ensure that there is sufficient drainage air pressure in the water collecting tank 10.
[0036] Working principle: When in use, start the fan 1, and the cold air enters the wind bag 4 through the delivery pipe 2. The temperature sensor 9 detects the temperature of the bottom of the horizontal passage and the branch passage. When the temperature of a temperature sensor 9 is high, it transmits a signal to the controller. The controller receives and processes the signal, and at the same time sends a signal to start the corresponding regulating valve 8 (the regulating valve 8 located below the temperature sensor 9), so that the regulating valve 8 adjusts the opening and the air volume flowing inside it to achieve the purpose of precise cooling.
