Description

Technical Field

[0001] The present invention relates to the technical field of glass manufacturing, and in particular to a liquid crystal substrate glass pool furnace charge mountain control device and method. Background Art

[0002] In daily substrate glass production, melting is the core process of glass manufacturing. The flow of the glass melt is very complex and has a direct impact on product quality and yield. The flow of the melt is reflected in the shape of the raw material pile. Therefore, ensuring a stable and good pile shape is of great significance to LCD glass production.

[0003] Existing methods for controlling the material pile primarily include current adjustment, gas volume adjustment, and coke clearing. Current adjustment influences the convection of the molten glass inside the tank furnace by varying the current flowing through the heating electrodes, thereby controlling the shape of the material pile. Gas volume adjustment influences the shape of the material pile by adjusting the gas volume at the burner lance to control the top temperature of the furnace. Coke clearing, as a means of restoring the tank furnace process, is typically performed when the process reaches its risk limit. The key features and primary functions of these existing technologies lie in their attempt to maintain the stability of the material pile by adjusting current, gas volume, or performing coke clearing, thereby ensuring a smooth glass production process.

[0004] However, the above-mentioned existing technologies have exposed many problems and shortcomings in actual application. Current adjustment has the disadvantages of being difficult to operate and having a slow adjustment effect, making it difficult to achieve timely and accurate control of the shape of the material mountain; gas volume adjustment mainly acts on the upper layer of molten glass, and has limited effect on the adjustment of the overall shape of the tank furnace material mountain, and cannot effectively solve the problem of material mountain deflection; although the decoking operation can restore the tank furnace process to a certain extent, it has a negative impact on the stability of glass quality and the life of the tank furnace channel, and frequent operations will lead to production interruptions and reduce production efficiency. These shortcomings limit the product quality and production efficiency in the production process of liquid crystal substrate glass, and have become a technical bottleneck that urgently needs to be broken through.

[0005] In summary, a new material mountain management technology solution is urgently needed to effectively solve the problems existing in the existing technology, such as difficulty in adjustment, poor results, and negative impact on equipment and process stability, so as to meet the market demand for high-quality liquid crystal substrate glass and efficient production. Summary of the Invention

[0006] The purpose of the present invention is to provide a liquid crystal substrate glass pool furnace material mountain control device and method to overcome the technical problem of the prior art that the material mountain shape is unstable due to poor material mountain adjustment effect.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] In a first aspect, the present invention provides a liquid crystal substrate glass pool furnace charge mountain control device, comprising:

[0009] The pool furnace has a main feeding system in front of it, which includes a feeding port and a feeding machine connected to the pool furnace through the feeding port;

[0010] The auxiliary feeding system includes a plurality of compensation feeding ports and a compensation feeding machine. The compensation feeding machine is provided with an auxiliary feeding port and a connecting portion. The compensation feeding port allows the compensation feeding machine to be detachably connected to the compensation feeding port through the connecting portion.

[0011] The compensation feeding port is arranged on the side wall of the pool furnace.

[0012] The compensation feeding ports are arranged on the side walls on both sides of the pool furnace and are arranged symmetrically.

[0013] The auxiliary feeding system is provided with 4 to 6 groups, and the compensation feeding port is arranged in accordance with the flow direction of the glass melt in the pool furnace.

[0014] A connecting portion is protruding from one side of the lower portion of the compensating feeder, and the upper portion thereof is a bucket-shaped feeding port, and the compensating feeding port allows the connecting portion to be connected and fixed.

[0015] The diameter of the bucket-shaped feeding port of the compensating feeding machine is larger than the diameter of the feeding machine of the main feeding system.

[0016] The connecting part of the compensating feeder and the compensating feed port are fixed by limit bolts.

[0017] The compensation feeding port is closed by a plug when not in use.

[0018] It also includes an industrial television monitoring system that allows real-time acquisition of images of the material mountain morphology.

[0019] In a second aspect, the present invention provides a method for controlling a liquid crystal substrate glass pool furnace charge mountain, comprising:

[0020] S1, determine whether the material pile status has shifted through the industrial television monitoring system;

[0021] S2, selecting a material pile compensation position according to the material pile status image;

[0022] S3, open the plug corresponding to the compensation position of the material mountain, connect the compensation feeder and fix it;

[0023] S4, start the compensation feeder to correct the material mountain. During this period, observe the state of the material mountain to determine whether the material mountain compensation position needs to be adjusted. If necessary, repeat S2 to S3 until the material mountain correction is completed.

[0024] S4, start the compensation feeder to correct the material mountain. During this period, observe the status of the material mountain to determine whether the material mountain compensation position needs to be adjusted. If necessary, repeat S2 to S3 until the material mountain correction is completed. It also includes reducing the opening of the feeder of the main feeding system when performing the material mountain correction.

[0025] Compared with the prior art, the present invention has the following beneficial technical effects:

[0026] In the first aspect, the present invention provides a liquid crystal substrate glass pool furnace charge mountain control device, which provides a direct and flexible means for adjusting the shape of the charge mountain by arranging a compensation feed port and a detachable matching compensation feeder on the side wall of the pool furnace. The auxiliary feeding system in this solution can perform local compensation for the specific part of the charge mountain deflection, and directly feed raw materials into the deflection area through the compensation feeder, changing the temperature and flow state of the glass melt in the area, thereby having a direct impact on the shape of the charge mountain and quickly correcting the deflection of the charge mountain. The compensation feed port is provided on the side wall of the pool furnace. This design enables the compensation feeder to directly enter the deflection area from the side, avoiding the uneven heat distribution and interference with the flow field that may be caused by the traditional feeding method. At the same time, the detachable connection method of the compensation feed port not only ensures that the compensation feeder can be quickly installed for operation when compensation is required, but also can close the feed port by a plug when not needed to prevent heat loss and impurities from entering, thereby ensuring the stability of the internal environment of the pool furnace. Compared with traditional global adjustment methods, this local and direct compensation method is more flexible and targeted, and can more effectively solve the problem of unstable material mountain shape caused by poor adjustment effect in existing technologies.

[0027] On the other hand, the present invention provides a method for controlling the material mountain in a liquid crystal substrate glass pool furnace. The industrial television monitoring system is used to determine in real time whether the material mountain state has shifted, and a suitable compensation position is selected based on the acquired material mountain state image. This method can ensure the pertinence and effectiveness of the compensation measures, and avoid blind adjustments caused by lack of precise positioning. After determining the compensation position, open the corresponding plug, connect and fix the compensation feeder, and then start the compensation feeder to correct the material mountain. During the feeding process, continuously observe the material mountain state, and determine whether the compensation position needs to be adjusted based on actual conditions. If necessary, repeat the relevant operations until the material mountain correction is completed. This method that combines dynamic monitoring and adjustment can respond in a timely manner according to real-time changes in the shape of the material mountain, ensuring the continuity and effectiveness of the correction process.

[0034] In the production of liquid crystal substrate glass, existing methods for controlling the pile of molten glass primarily include current adjustment, gas volume adjustment, and de-coking. Current adjustment influences the convection of the molten glass within the furnace by varying the current flowing through the heating electrodes, thereby controlling the pile's shape. Gas volume adjustment modulates the furnace top temperature by adjusting the gas volume through the burner lance, thereby influencing the pile's shape. De-coking, as a means of restoring the furnace process, is typically performed when the process reaches its risk limit. The key features and primary functions of these existing technologies lie in their attempt to maintain a stable pile of molten glass by adjusting current, gas volume, or performing de-coking, thereby ensuring a smooth glass production process.

[0035] However, existing technologies have exposed numerous problems and shortcomings in practical applications. Current adjustment is difficult to operate and has slow effects, making it difficult to achieve timely and precise control of the shape of the charge mountain. Gas volume adjustment primarily affects the upper layer of molten glass, with limited effect on the overall shape of the tank furnace charge mountain and unable to effectively resolve the problem of charge mountain deflection. While decoking operations can restore the tank furnace process to a certain extent, they have a negative impact on the stability of glass quality and the life of the tank furnace channels. Frequent operations can lead to production interruptions and reduced production efficiency. These shortcomings limit product quality and production efficiency in the production of liquid crystal substrate glass, and have become technical bottlenecks that urgently need to be overcome.

[0036] In summary, the liquid crystal substrate glass production industry is in urgent need of a new material mountain control technology solution to effectively solve the problems existing in the existing technology, such as the difficulty of adjustment, poor results, and negative impact on equipment and process stability, and to meet the market demand for high-quality liquid crystal substrate glass and efficient production. Therefore, how to overcome the shortcomings of the existing liquid crystal substrate glass pool furnace material mountain control technology has become a key issue that needs to be urgently solved by those skilled in the art. It is based on this background that the present invention is proposed, and aims to provide a liquid crystal substrate glass pool furnace material mountain control solution that can accurately and effectively improve the shape of the material mountain, while reducing disturbances to the pool furnace and improving product quality.

[0041] Reference Figure 1 The figure shows a specific embodiment of the liquid crystal substrate glass pool furnace charge mountain control device provided by the present invention, comprising:

[0042] The pool furnace 6 has a main feeding system in front of it, which includes a feeding port 1 and a feeding machine 3 connected to the pool furnace 6 through the feeding port 1;

[0043] The auxiliary feeding system includes a plurality of compensation feeding ports 5 and a compensation feeding machine 4. The compensation feeding machine 4 is provided with an auxiliary feeding port and a connecting portion. The compensation feeding port 5 allows the compensation feeding machine 4 to be detachably connected to the compensation feeding port 5 through the connecting portion.

[0044] The compensation feeding port 5 is arranged on the side wall of the pool furnace 6.

[0045] Specifically, the main feeding system in this embodiment includes a feeding port 1 and a feeding machine 3 connected thereto, which is used for conventional raw material feeding. The auxiliary feeding system includes several compensation feeding ports 5 and compensation feeding machines 4. The structure of the compensation feeding machine 4 is shown in FIG. Figure 2 As shown. The compensation feeding port 5 is set on the side wall of the pool furnace 6. When not in use, it can be closed by the plug 2 to prevent heat loss and impurities from entering. The structure of the plug 2 refers to Figure 3 As shown, the compensating feeder 4 is designed with a connecting portion and a bucket-shaped feed opening. The connecting portion is fixedly connected to the compensating feed opening 5 via a limit bolt. The diameter of the bucket-shaped feed opening is larger than that of the feeder 3 of the main feeding system, facilitating the rapid feeding of raw material when the pile deflects. The device is also equipped with an industrial television monitoring system for real-time image capture of the pile's morphology, enabling accurate assessment of its condition and determination of the compensation position.

[0046] During the construction of the tank furnace 6, compensation feed ports 5 were reserved on both sidewalls and arranged symmetrically to ensure effective compensation from both sides in the event of a deflected material mountain. Four to six auxiliary feeding systems were installed, positioned to align with the flow direction of the molten glass within the tank furnace 6, ensuring that the compensating feed precisely affected the shape of the material mountain. This layout, through the rational placement of the compensation feed ports 5, more effectively leveraged the natural flow of the molten glass to adjust the shape of the material mountain, thereby reducing problems such as excessive melting pressure in the front area of the tank furnace 6 and unstable glass quality caused by material mountain deflection.

[0047] During use, the shape of the material mountain is monitored in real time through the industrial TV monitoring system. Figure 4 As shown, when the material mountain deflects, a suitable compensation position is selected according to the monitoring image, the corresponding plug 2 is opened, and the compensating feeder 4 is connected and fixed. The compensating feeder 4 is started to feed raw material into the deflected part to adjust the temperature and flow state of the glass melt in this area, thereby improving the shape of the material mountain. During the feeding process, if necessary, the opening of the feeder 3 of the main feeding system can be reduced to reduce the melting pressure in the front zone and improve the melting efficiency of the pool furnace 6. After the shape of the material mountain returns to normal, the compensating feeder 4 is pulled out, the plug 2 is plugged, and the original opening of the feeder 3 is restored in multiple times to ensure the stability of the operation of the pool furnace 6.

[0048] This device effectively improves the shape of the pile, extends the coke cleaning cycle, reduces disturbances to the furnace caused by stationary operations, and improves product quality and production efficiency. Through precise local compensation and rapid dynamic adjustment, it directly addresses the core problem areas of pile deflection, while simultaneously balancing process stability and product quality optimization.

[0049] The present invention also provides a liquid crystal substrate glass pool furnace charge mountain control method. In a specific embodiment of the method, a liquid crystal substrate glass pool furnace control device as described above can be used to correct the charge mountain shape in liquid crystal substrate glass production. The method specifically includes the following steps:

[0050] S1, determine whether the material pile status has shifted through the industrial television monitoring system;

[0051] S2, selecting a material pile compensation position according to the material pile status image;

[0052] S3, open the plug 2 corresponding to the compensation position of the material mountain, connect the compensation feeder 4 and fix it;

[0053] S4, start the compensation feeder 4 to correct the material mountain. During this period, observe the state of the material mountain to determine whether the material mountain compensation position needs to be adjusted. If necessary, repeat S2 to S3 until the material mountain correction is completed.

[0054] Specifically, the method uses an industrial television monitoring system to obtain a real-time image of the material mountain shape and determine whether the state of the material mountain has shifted, so as to promptly discover and deal with problems. After determining that the material mountain has shifted, the position of the material mountain that needs to be compensated is selected based on the image analysis of the material mountain state, providing a clear target for subsequent feeding operations. Open the plug 2 corresponding to the selected material mountain compensation position, connect the compensation feeder 4 to the compensation feeding port 5, and fix the connection part of the compensation feeder 4 to the compensation feeding port 5 through the limit bolt to ensure the stability and accuracy of the feeding process. Start the compensation feeder 4 to feed raw materials into the deflected part, so as to adjust the temperature and flow state of the glass melt in this area, thereby improving the shape of the material mountain. During the feeding process, observe the state of the material mountain. If the material mountain compensation position needs to be adjusted, repeat the steps of selecting the compensation position and connecting the compensation feeder until the material mountain is corrected. When correcting the material mountain, reduce the opening of the feeder 3 of the main feeding system to reduce the melting pressure in the front zone, improve the melting efficiency of the pool furnace 6, and help to better achieve the adjustment of the material mountain shape. After the shape of the material mountain returns to normal, pull out the compensation feeder 4, plug it with the plug 2, and gradually restore the opening of the original feeder 3 in several times to ensure the stability of the operation of the pool furnace 6 and avoid adverse effects on the pool furnace 6 due to excessive or insufficient opening of the feeder.

[0055] In order to make the liquid crystal substrate glass pool furnace charge mountain control device and method provided by the present invention easier to understand, a specific implementation method combined with actual usage scenarios is provided below for further explanation.

[0056] Taking a certain liquid crystal substrate glass production line as an example, the pool furnace (6) of the production line is equipped with the material mountain control device provided by the present invention, wherein the main feeding system includes a feeding port 1 and a feeding machine 3, providing a stable raw material input for conventional production. At the same time, on both sides of the pool furnace 6, there are two sets of auxiliary feeding systems, which are symmetrically distributed, totaling four sets. Each set includes a compensation feeding port 5 and a compensation feeding machine 4, which are used to cope with local adjustments to the shape of the material mountain.

[0057] During the production process, the shape of the material mountain is monitored in real time through the industrial television monitoring system to determine whether there is any deviation. Once the material mountain is found to be deflected, the compensation position is immediately determined based on the monitoring image. The operator quickly opens the plug 2 at the corresponding position, connects the compensation feeder 4 to the compensation feed port 5, and fixes it with limit bolts to ensure the stability and reliability of the feeding process. The compensation feeder 4 is then started, and an appropriate amount of raw material is fed into the deflected area. By adjusting the temperature and flow state of the local glass melt, the shape of the material mountain is quickly improved. During the feeding process, the operator continuously observes the state of the material mountain. If the compensation position needs to be adjusted, the relevant operations are repeated until the shape of the material mountain returns to normal.

[0058] During this process, to further optimize the melting efficiency of the pool furnace 6, the opening of the main feeding system's feeder 3 is appropriately reduced to reduce the melting pressure in the front zone. After the shape of the material mountain is adjusted, the operator removes the compensation feeder 4, seals the compensation feed port 5 with a plug 2, and gradually restores the normal opening of the main feeder 3 to ensure the stability of the pool furnace 6 operation and avoid adverse effects on the pool furnace 6 caused by excessive or insufficient feeder openings.

[0059] The device and method for controlling the pile of liquid crystal substrate glass in a tank furnace, provided by this invention, effectively resolve the technical challenge of unstable pile shape in this production line. In actual production, the pile shape is precisely controlled, the coke cleaning cycle is extended, and the operational stability of the tank furnace 6 is significantly improved. Furthermore, the stable pile shape improves product quality and increases production efficiency by reducing production interruptions caused by pile problems.

[0060] The liquid crystal substrate glass pool furnace charge mountain control device and method provided by the present invention can effectively overcome the technical problem in the prior art that the charge mountain shape is unstable due to poor charge mountain adjustment effect. The current adjustment and gas volume adjustment means commonly used in the prior art have problems such as slow response and low precision, making it difficult to accurately compensate for the deflected parts of the charge mountain. However, this solution, by providing multiple compensation feeding ports 5 and a matching compensation feeding machine 4, can accurately locate the deflection area of the charge mountain based on the real-time image of the industrial television monitoring system, and directly feed the raw material into the area, quickly changing the temperature and flow state of the local glass melt, and realizing effective adjustment of the charge mountain shape.

[0061] During the adjustment process, operators can flexibly adjust the feed rate and feed position of the compensation feeder 4 based on the dynamic changes in the pile shape, achieving rapid response and immediate adjustment. This direct raw material compensation method can more quickly improve the pile shape than traditional technologies, reducing the problem of excessive melting pressure in the front area of the tank furnace caused by pile deflection. Furthermore, by reducing the opening of the feeder 3 of the main feeding system during pile correction, this solution further optimizes the flow of the molten glass and improves the melting efficiency of the tank furnace 6.

[0062] Furthermore, this design fully considers maintaining the overall process stability of tank furnace 6. When compensatory feeding is not in progress, compensatory feed port 5 can be sealed with plug 2 to prevent heat loss and impurities from entering, maintaining a stable internal environment in tank furnace 6. After the pile of material is corrected, compensatory feeder 4 is removed, compensatory feed port 5 is resealed, and the opening of feeder 3 in the main feeding system is gradually restored to ensure a smooth transition in the operation of tank furnace 6. This design improves the shape of the pile of material while minimizing disruption to the normal operation of tank furnace 6, overcoming the problem of unstable pile shape caused by limited adjustment methods in the prior art.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention.
