Description

Technical Field

[0001] The invention belongs to the field of overflow down-draw flat glass manufacturing, and in particular relates to an overflow brick and guide plate crystallization monitoring device and a use method thereof. Background Art

[0002] In the overflow down-draw method, a highly precise substrate glass production system, the molten glass first passes through a carefully designed overflow brick structure and uses surface tension to smoothly overflow at the edge of the brick. Subsequently, the overflowing glass converges at the root area of ​​the overflow brick and gradually merges into a continuous and uniform glass ribbon. This process not only relies on precise process control, but also highly relies on the synergy of gravity and precision traction devices, which together ensure that the substrate glass ribbon can maintain a stable thickness and speed and extend forward.

[0003] However, overflow bricks, as key components, will gradually creep due to the long-term pressure of high-temperature molten glass and the thermal stress of their own materials. Creep not only causes slight changes in the shape and size of overflow bricks, but may also cause the redistribution of internal stress in the brick body, thereby increasing the risk of cracks in overflow bricks. Once these cracks are formed, they will directly affect the stability of the molten glass during the overflow process, causing uneven thickness of the glass ribbon and affecting the quality of the final product.

[0004] In addition, in the guide plate area, trace impurities in the glass liquid will begin to precipitate and gradually form tiny crystal nuclei after reaching a specific crystallization temperature. These crystal nuclei continue to grow in a continuous high temperature environment, gradually changing the flow characteristics of the glass liquid and interfering with the originally designed flow path and flow state. This change in flow state, especially in the area near the edge of the glass ribbon, often leads to the deterioration of the quality of the glass edge plate, manifested as uneven edges, large thickness fluctuations and other problems, which in turn affects the stability of the entire production line and the yield rate of the product. Summary of the invention

[0005] The object of the present invention is to overcome the above-mentioned problems and provide an overflow brick and guide plate crystallization monitoring device and a method of use, which can monitor the crystallization state of the overflow brick and the guide plate and provide a judgment basis for the crystallization treatment.

[0006] In order to achieve the above object, the present invention adopts the following technical solution: In the first aspect, the present invention provides an overflow brick and guide plate crystallization monitoring device, comprising a high-temperature resistant video recorder and a thermal imager, wherein the high-temperature resistant video recorder is connected to the thermal imager and a monitoring action mechanism, wherein the monitoring action mechanism is fixed on a furnace body, and an installation base plate is provided on the furnace body, wherein a reserved hole is provided at the center of the installation base plate, and the high-temperature resistant video recorder and the thermal imager enter the furnace body through the reserved hole to monitor the crystallization status of the overflow brick and the guide plate in real time.

[0007] A further improvement of the present invention is that a furnace wall steel structure is arranged on the furnace body, and the mounting bottom plate is arranged on the furnace wall steel structure.

[0008] A further improvement of the present invention is that the mounting base plate is fixedly connected to the furnace wall steel structure by screws.

[0009] A further improvement of the present invention is that the number of the screws is 4, and the 4 screws are respectively located at the four corners of the mounting base plate.

[0010] A further improvement of the present invention is that the high temperature resistant video recorder and the thermal imager are respectively provided with a cooling water inlet pipe and a cooling water return pipe.

[0011] A further improvement of the present invention is that the high temperature resistant video recorder and the thermal imager are externally covered with a cooling cover.

[0012] A further improvement of the present invention is that the high temperature resistant video recorder and the thermal imager are connected to the computer via a transmission wire.

[0013] A further improvement of the present invention is that the size of the reserved hole is compatible with the size of the high temperature resistant video recorder and the thermal imager.

[0014] A further improvement of the present invention is that the high temperature resistant video recorder and the thermal imager are connected to the monitoring action mechanism via a monitoring connection mechanism.

[0015] In a second aspect, the present invention further provides a method for using an overflow brick and a guide plate crystallization monitoring device, comprising the following steps: Step 1: The high temperature resistant video recorder and the thermal imager are spirally advanced toward the furnace body along the monitoring action mechanism; Step 2: The high temperature resistant video recorder and the thermal imager enter the furnace body through the reserved holes on the installation base plate; Step 3: Use a high temperature video recorder and a thermal imager to record and collect data on the crystallization state of the overflow bricks and guide plates in the furnace body; Step 4: After the video recording and data collection are completed, the high temperature resistant video recorder and thermal imager exit the furnace.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides an overflow brick and guide plate crystallization monitoring device. By connecting a high-temperature resistant video recorder and a thermal imager to a monitoring action mechanism, and fixing the monitoring action mechanism on a furnace body, the fixed installation of the monitoring action mechanism ensures that the monitoring device can still maintain stable operation under harsh working conditions such as high temperature and vibration. The angle and position of the monitoring device can also be adjusted as needed to obtain the best monitoring viewing angle. This flexibility enables the monitoring system to adapt to different furnace types and process requirements, and improves its applicability and flexibility. In addition, this stable connection relationship helps to reduce monitoring interruptions caused by equipment shaking or falling off, and improves the reliability and stability of the monitoring system. At the same time, the high-temperature resistant video recorder and the thermal imager enter the furnace body through the reserved hole in the center of the installation bottom plate, and realize direct observation of the high-temperature environment. This design makes data acquisition more efficient, and there is no need to set up additional complex transmission paths or conversion equipment, thereby simplifying the system structure and improving work efficiency. The present invention realizes real-time monitoring of the crystallization state of the overflow brick and the guide plate through a reasonable device connection relationship, provides a judgment basis for crystallization processing, and also improves the efficiency of data acquisition and the stability and flexibility of the monitoring system.

[0017] Furthermore, the high temperature resistant video recorder and the thermal imager are respectively provided with a cooling water inlet pipe and a cooling water return pipe. In a high temperature working environment, the electronic components of the high temperature resistant video recorder and the thermal imager will generate a large amount of heat. The introduction of cooling water through the cooling water inlet pipe can absorb the heat and take the heat away through the cooling water return pipe, thereby ensuring that the internal temperature of the equipment is maintained within a safe range and preventing performance degradation or damage due to overheating. The presence of the cooling system can significantly reduce the temperature fluctuation inside the equipment and reduce the thermal stress caused by temperature changes, thereby improving the stability and reliability of the equipment.

[0018] Furthermore, a cooling cover is provided on the outside of the high-temperature resistant video recorder and the thermal imager, which can effectively conduct the heat generated inside the high-temperature resistant video recorder and the thermal imager to the external environment, thereby preventing the equipment from being damaged or the performance from being degraded due to high temperature. The cooling cover can also maintain the internal temperature of the equipment stable, reduce the impact of temperature fluctuations on the performance of the equipment, and ensure that the equipment can maintain high precision and high stability even in harsh environments. In addition, the cooling cover has good sealing properties, which can prevent dust, moisture and other impurities from entering the equipment, thereby protecting the equipment from erosion by environmental factors. It can also provide certain mechanical protection for the equipment, reduce damage to the equipment caused by external shocks or vibrations, and ensure the stable operation of the equipment under complex working conditions.

[0019] Furthermore, the high temperature resistant video recorder and thermal imager are connected to the computer through a transmission guide. Through the transmission guide, the high temperature resistant video recorder and thermal imager can transmit the collected video and temperature data to the computer in real time, so that the operator can instantly view and analyze the on-site situation without waiting for data export or transmission. Real-time data transmission not only improves the monitoring efficiency, so that any abnormal situation can be quickly discovered and handled, but also avoids safety hazards caused by data transmission delays.

[0020] Furthermore, the size of the reserved hole is compatible with the size of the high-temperature resistant video camera and the thermal imager. The high-temperature resistant video camera and the thermal imager can easily and quickly pass through the reserved hole into the furnace body, which helps to maintain the sealing around the equipment and prevent heat loss in a high-temperature environment and the intrusion of external factors such as dust and impurities.

[0021] The present invention also provides a method for using an overflow brick and guide plate crystallization monitoring device, comprising: a high-temperature resistant video recorder and a thermal imager are spirally advanced toward a furnace body along a monitoring action mechanism, and then enter the furnace body through a reserved hole on an installation bottom plate, and the crystallization status of the overflow brick and the guide plate in the furnace body is recorded and data is collected. After the recording and data collection are completed, the high-temperature resistant video recorder and the thermal imager exit the furnace body; by means of spiral advancement, the high-temperature resistant video recorder and the thermal imager can quickly and accurately locate the target position in the furnace body, thereby efficiently performing the recording and data collection tasks. Once entering the furnace body, the high-temperature resistant video recorder and the thermal imager can accurately evaluate the crystallization status of the overflow brick and the guide plate. The entire monitoring process does not require personnel to directly enter the high-temperature furnace body, thereby reducing operational risks and ensuring the safety of staff.
