Description

Technical Field

[0001] The invention belongs to the technical field of furnace batching melting state detection, and in particular relates to a mechanism and method for detecting the melting edge state of a substrate glass furnace batching. Background Art

[0002] With the improvement of the production level of liquid crystal substrate glass and the vigorous development of the tertiary industry, the demand for high-generation substrate glass products has increased significantly, and the construction of large-capacity kilns has begun to be laid out, which results in a large-tonnage melting process in the kiln. The moving speed of the edge of the ingredients and the maturity of the process determine the quality of the glass. In order to achieve large-scale production, it is necessary to adopt some corresponding high-tech process control measures.

[0003] Glass melting furnace is an important link in various glass processing technologies. It is used to melt glass batches. The raw materials formulated according to the glass composition are heated, melted and clarified in the furnace to produce glass liquid that meets the requirements of subsequent links. In this process link, the raw materials added to the glass melting furnace from the feeding port are completely converted into a molten state. At this time, it is very important to detect the edge position and temperature of the batch melt.

[0004] If the edge of the melt moves backward too quickly and the temperature is too low, the raw materials that have not been converted into a molten state may be carried downstream, thereby affecting the quality of the produced glass; if it moves too slowly, it means that the speed of conveying the raw materials is slower than the process requirements, which will produce unnecessary effects and reduce the throughput of the process production. At present, the process control of glass raw material melting is limited to manually determining the feeding speed and feeding amount through the frequency control of the feeder. Subjective factors play a big role. If there is a deviation in the judgment, the entire process control fails, and the product with good performance cannot be produced, resulting in a waste of raw materials, energy, and labor costs, and huge economic losses. Summary of the invention

[0005] The purpose of the present invention is to provide a substrate glass furnace melting material melting edge state detection mechanism and method to solve the technical defect of manually determining the feeding speed and feeding amount through the frequency control of the feeding machine, resulting in process control failure.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: On the one hand, a mechanism for detecting the melting edge state of a substrate glass furnace melt batch is provided, comprising: Guide assembly, installed outside the kiln; A cooling assembly is installed on the guide assembly, and a purge assembly is installed on the cooling assembly; A detection device, disposed in the cooling assembly, for detecting a melting edge state of the batch material in the kiln; A control device, electrically connected to the guide assembly, the cooling assembly, the purge assembly and the detection device; Wherein, when detecting the melting edge state of the ingredients in the kiln, the control device controls the guide assembly to drive the detection device to enter the interior of the kiln for detection.

[0007] Furthermore, the detection device comprises a material melting edge state collecting component, the material melting edge state collecting component is installed in the cooling assembly, and a quartz protective screen is installed at the collecting end of the material melting edge state collecting component; One end of the purge assembly is mounted on the cooling assembly and is used to purge the ingredient melting edge state collecting member, and the other end of the purge assembly is connected to an external gas supply device.

[0008] Furthermore, the ingredient melting edge state acquisition component is a thermal imaging camera, and the thermal imaging camera is used to acquire an ingredient melting edge state image. The cooling assembly includes a water cooling jacket, and the thermal imaging camera is installed in the water cooling jacket; A pipeline is welded on the water cooling jacket, one end of the pipeline is connected to an external water supply device, and the other end of the pipeline is communicated with the inside of the water cooling jacket.

[0009] Furthermore, an alloy shield is installed on the thermal imaging camera.

[0010] Further, the purge assembly includes a purge pipe and a bracket, the bracket is mounted on the guide assembly, and the purge pipe is mounted on the bracket; Among them, one end of the purge pipe is directed toward the ingredient melting edge state collection piece, and the other end is connected to the external gas supply equipment.

[0011] Furthermore, the control device has a built-in image processing module, and the image processing module is used to process the detected image of the melting edge state of the ingredients in the kiln.

[0012] Furthermore, the guide assembly includes a guide rail and a slider, one end of the guide rail extends to the inside of the kiln, and the other end is located outside the kiln, the slider is slidably connected to the guide rail, and a driving assembly and a detection device are installed on the slider, and the driving assembly is used to drive the slider to drive the detection device to perform linear reciprocating motion.

[0013] Furthermore, the driving assembly includes a cylinder and an air pump, the air pump is installed on the guide rail, and the driving end of the cylinder is connected to the slider; or, the driving assembly includes a hydraulic rod and a hydraulic cylinder, the hydraulic cylinder is installed on the guide rail, and the driving end of the hydraulic rod is connected to the slider.

[0014] Furthermore, a thermal resistor is installed on the detection device, and the thermal resistor is electrically connected to the control device.

[0015] In a second aspect, a method for detecting the melting edge state of a substrate glass furnace melt batch is provided, the method being performed using the detection mechanism as described above, comprising: Collect images of melting edge state changes of ingredients in the kiln; Analyzing and processing the collected images; Mark state changes in processed images.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. By installing a detection device inside the kiln and using the precise control of the guide assembly, it is possible to achieve real-time and accurate detection of the melting edge state of the ingredients in the kiln, which is crucial for monitoring the quality of the melting process, timely discovering and preventing possible problems such as uneven melting and edge condensation, and helps to improve the quality stability and consistency of glass products. The automated detection process reduces the need for manual intervention, which not only improves detection efficiency but also reduces the safety risks of operators. At the same time, the controller enables production management personnel to respond to problems quickly, adjust production processes, avoid problems from expanding, and thus improve overall production efficiency. Finally, the combined use of cooling components and purge components can effectively reduce the temperature of the detection device and the surrounding environment, prevent high temperature from damaging the equipment, extend the service life of the equipment, facilitate equipment cleaning and maintenance, and reduce failures caused by environmental factors such as high temperature and dust.

[0017] 2. The batch melting edge state acquisition unit is installed in the cooling assembly, and its acquisition end is protected by a quartz screen. The quartz material has excellent high-temperature stability and chemical inertness, which can effectively isolate the high-temperature environment and corrosive gases in the kiln, protect the acquisition unit from damage, and ensure its long-term stable operation and accurate data collection. The quartz screen not only protects the acquisition unit, but also reduces the interference of impurities such as dust and steam in the kiln to the acquisition process, and improves the clarity and accuracy of data collection. This is crucial for accurately analyzing the edge state of batch melting and timely discovering potential problems. The design of the purge component regularly or continuously purges the batch melting edge state acquisition unit to remove impurities and dirt attached to the acquisition end and the quartz screen, ensuring that the acquisition unit always maintains the best working condition and improves the reliability and continuity of data collection.

[0018] The combined effect of the cooling component and the purge component effectively reduces the temperature of the collection part and its surrounding environment, and reduces the wear and corrosion caused by high temperature and pollution. This helps to extend the service life of the equipment and reduce maintenance costs.

[0019] 3. Thermal imaging cameras can capture the temperature distribution image of the melting edge of the ingredients in the kiln in real time and provide high-precision temperature data, which is of great significance for analyzing the thermal behavior of the ingredients during melting, judging whether the melting state is uniform, and predicting potential problems; and the water cooling jacket provides a low-temperature and stable working environment for the thermal imaging camera. Through the circulating cooling water, the water cooling jacket can quickly take away the heat generated by the camera and the high-temperature radiation from the kiln, protecting the camera from high-temperature damage and ensuring its long-term stable operation. The water cooling jacket not only reduces the temperature of the camera, but also reduces the image distortion and noise caused by high temperature, improves the clarity and accuracy of data acquisition, and enables production management personnel to more accurately judge the state of the melting edge of the ingredients, providing a reliable basis for production decisions.

[0020] 4. The alloy shield, as the outer protective layer of the thermal imaging camera, can effectively resist the high temperature environment in the kiln. Since the temperature inside the kiln is extremely high, ordinary materials cannot withstand it. However, the alloy material, due to its excellent high temperature resistance, can ensure the normal operation of the camera under high temperature conditions and extend the service life of the equipment.

[0021] 5. One end of the purge pipe is facing the material melting edge state collection part (such as a thermal imaging camera), which can be purged regularly or as needed to remove dust, steam and other impurities attached to the lens or collection surface. This helps to keep the collection part clean, ensure that the collected image is clear and accurate, and improve the reliability of data collection. The bracket is installed on the guide assembly, so that the purge pipe can flexibly adjust its position as the guide assembly moves, so that the purge assembly can accurately align with the collection part to ensure the maximum purge effect. At the same time, it also adapts to the complex and changeable environment inside the kiln, and improves the adaptability and flexibility of the detection mechanism.

[0022] 6. The image processing module can pre-process the detected image of the melting edge state of the ingredients in the kiln, such as denoising, contrast enhancement, sharpening, etc., so as to improve the image quality and make the image clearer and more accurate. This will help the subsequent analysis work to proceed smoothly and improve the accuracy and reliability of data processing.

[0023] 7. The linear extension of the guide rail ensures that the slider can perform precise linear reciprocating motion along the predetermined path, so that the detection device can accurately locate different positions of the melting edge of the ingredients in the kiln for detailed image acquisition and status analysis.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0026] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention.

In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0029] In addition, if the term "horizontal" appears, it does not mean that the component is required to be absolutely horizontal, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", which does not mean that the structure must be completely horizontal, but can be slightly tilted.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] With the improvement of the production level of liquid crystal substrate glass and the vigorous development of the tertiary industry, the demand for high-generation substrate glass products has increased significantly, and the construction of large-capacity kilns has begun to be laid out, which results in a large-tonnage melting process in the kiln. The moving speed of the edge of the ingredients and the maturity of the process determine the quality of the glass. In order to achieve large-scale production, it is necessary to adopt some corresponding high-tech process control measures.

The raw materials formulated according to the glass composition are heated, melted and clarified in the furnace to produce glass liquid that meets the requirements of subsequent links. In this process link, the raw materials added to the glass melting furnace from the feeding port are completely converted into a molten state. At this time, it is very important to detect the edge position and temperature of the batch melt.

[0033] If the edge of the melt moves backward too quickly and the temperature is too low, the raw materials that have not been converted into a molten state may be carried downstream, thereby affecting the quality of the produced glass; if it moves too slowly, it means that the speed of conveying the raw materials is slower than the process requirements, which will produce unnecessary effects and reduce the throughput of the process production. At present, the process control of glass raw material melting is limited to manually determining the feeding speed and feeding amount through the frequency control of the feeder. Subjective factors play a big role. If there is a deviation in the judgment, the entire process control fails, and the product with good performance cannot be produced, resulting in a waste of raw materials, energy, and labor costs, and huge economic losses.

[0034] In order to solve the above technical defects, the inventor provides a mechanism and method for detecting the melting edge state of the melting ingredients in a substrate glass furnace.

[0035] The present invention is further described in detail below in conjunction with the accompanying drawings: In a first aspect of the present embodiment, a mechanism for detecting the melting edge state of a melting ingredient in a glass substrate kiln is provided, comprising: a guide assembly installed on the outside of the kiln; a cooling assembly installed on the guide assembly, and a purge assembly installed on the cooling assembly; a detection device, arranged in the cooling assembly, for detecting the melting edge state of the ingredient in the kiln; a control device, electrically connected to the guide assembly, the cooling assembly, the purge assembly and the detection device; wherein, when detecting the melting edge state of the ingredient in the kiln, the control device controls the guide assembly to drive the detection device to enter the kiln for detection, such as Figure 1 As shown. By setting up a detection device inside the kiln and relying on the precise control of the guide assembly, it is possible to achieve real-time and accurate detection of the melting edge state of the ingredients in the kiln, which is crucial for monitoring the quality of the melting process, timely discovering and preventing possible problems such as uneven melting and edge condensation, and helps to improve the quality stability and consistency of glass products. The automated detection process reduces the need for manual intervention, which not only improves detection efficiency but also reduces the safety risks of operators. At the same time, the controller enables production management personnel to respond to problems quickly, adjust production processes, avoid problems from expanding, and thus improve overall production efficiency. Finally, the combined use of cooling components and purge components can effectively reduce the temperature of the detection device and the surrounding environment, prevent high temperature from damaging the equipment, extend the service life of the equipment, facilitate equipment cleaning and maintenance, and reduce failures caused by environmental factors such as high temperature and dust.

[0036] In this embodiment, the detection device includes a batch melting edge state acquisition component, which is installed in the cooling assembly. A quartz screen is installed at the acquisition end of the batch melting edge state acquisition component. The quartz screen protects the acquisition end. The quartz material has excellent high-temperature stability and chemical inertness, and can effectively isolate the high-temperature environment and corrosive gases in the kiln, protect the acquisition component from damage, and ensure its long-term stable operation and accurate data collection. The quartz screen not only protects the acquisition component, but also reduces the interference of impurities such as dust and steam in the kiln on the acquisition process, and improves the clarity and accuracy of data collection. This is crucial for accurately analyzing the melting edge state of the batch and timely discovering potential problems. One end of the purge assembly is installed on the cooling assembly to purge the material melting edge state collection piece. The other end of the purge assembly is connected to the external gas supply device. The purge assembly is designed to purge the material melting edge state collection piece regularly or continuously to remove impurities and dirt attached to the collection end and the quartz screen, ensuring that the collection piece always maintains the best working condition and improves the reliability and continuity of data collection. Through the combined action of the cooling assembly and the purge assembly, the temperature of the collection piece and its surrounding environment is effectively reduced, and the wear and corrosion caused by high temperature and pollution are reduced. This helps to extend the service life of the equipment and reduce maintenance costs.

[0037] Furthermore, the component for collecting the melting edge state of the ingredients is a thermal imaging camera. The thermal imaging camera is used to collect images of the melting edge state of the ingredients and provide high-precision temperature data, which plays a decisive role in analyzing the thermal behavior of the ingredients during melting, judging whether the melting state is uniform, and predicting potential problems. The cooling component includes a water cooling jacket, in which the thermal imaging camera is installed. A pipe is welded on the water cooling jacket. One end of the pipe is connected to an external water supply device, and the other end is connected to the inside of the water cooling jacket. The water cooling jacket provides a low-temperature and stable working environment for the thermal imaging camera. Through the circulating cooling water, the water cooling jacket can quickly take away the heat generated by the camera and the high-temperature radiation from the kiln, protecting the camera from high-temperature damage and ensuring its long-term stable operation. The water cooling jacket not only reduces the temperature of the camera, but also reduces image distortion and noise caused by high temperature, improves the clarity and accuracy of data acquisition, and enables production management personnel to more accurately judge the state of the melting edge of the ingredients, providing a reliable basis for production decisions.

[0038] In this embodiment, an alloy shield is installed on the thermal imaging camera. The alloy shield serves as the external protective layer of the thermal imaging camera and can effectively resist the high temperature environment in the kiln. Since the temperature inside the kiln is extremely high, ordinary materials cannot withstand it. However, the alloy material, due to its excellent high temperature resistance, can ensure that the camera works normally under high temperature conditions and prolong the service life of the equipment. The purge assembly includes a purge pipe and a bracket. The bracket is installed on the guide assembly, and the purge pipe is installed on the bracket. One end of the purge pipe faces the material melting edge state collection part, and the other end is connected to the external gas supply device. One end of the purge pipe faces the material melting edge state collection part (such as a thermal imaging camera), and can purge the collection part regularly or as needed to remove dust, steam and other impurities attached to the lens or collection surface. This helps to keep the collection part clean, ensure that the collected image is clear and accurate, and improve the reliability of data collection. The bracket is installed on the guide assembly, so that the purge pipe can flexibly adjust its position as the guide assembly moves, so that the purge assembly can accurately align with the collection part to ensure the maximum purge effect. At the same time, it also adapts to the complex and changeable environment inside the kiln, and improves the adaptability and flexibility of the detection mechanism.

[0039] Furthermore, the control device has a built-in image processing module, and the image processing module is used to process the detected image of the melting edge state of the ingredients in the kiln. The image processing module can pre-process the detected image of the melting edge state of the ingredients in the kiln, thereby improving the image quality, making the image clearer and more accurate, and facilitating the smooth progress of subsequent analysis work, and improving the accuracy and reliability of data processing. The guide assembly includes a guide rail and a slider, one end of the guide rail extends to the inside of the kiln, and the other end is located outside the kiln. The slider is slidably connected to the guide rail, and a driving assembly and a detection device are installed on the slider. The driving assembly is used to drive the slider to drive the detection device to perform linear reciprocating motion. The linear extension of the guide rail ensures that the slider can perform precise linear reciprocating motion along a predetermined path, so that the detection device can accurately locate different positions of the melting edge of the ingredients in the kiln for detailed image acquisition and status analysis. Specifically, in one embodiment, the driving assembly includes a cylinder and an air pump, the air pump is installed on the guide rail, and the driving end of the cylinder is connected to the slider; or, in another embodiment, the driving assembly includes a hydraulic rod and a hydraulic cylinder, the hydraulic cylinder is installed on the guide rail, and the driving end of the hydraulic rod is connected to the slider.

[0040] Furthermore, a thermal resistor is installed on the detection device, and the thermal resistor is electrically connected to the control device. As a temperature sensor, the thermal resistor can monitor the temperature changes of the thermal imaging camera in real time and accurately, so that production management personnel can timely understand the temperature changes of the thermal imaging camera. At the same time, since the thermal resistor has high measurement accuracy and stability, it can ensure the accuracy of temperature data. After being electrically connected to the control device, the temperature data collected by the thermal resistor can be transmitted to the control device in real time for processing and analysis, thereby further improving the accuracy and reliability of the detection. Through the connection with the control device, the thermal resistor can realize linkage control with other equipment in the kiln.

[0041] In this embodiment, in addition to using the control device to perform real-time control on each component, each component can also be adjusted by manual assisted operation.

[0042] In a second aspect of the present embodiment, a method for detecting the melting edge state of a substrate glass furnace melt batch is provided, the method being performed using the detection mechanism as described above, and comprising: S101, collecting images of melting edge state changes of ingredients in the kiln; illustratively, the control device controls the movement of the guide component, thereby driving the detection device to enter the kiln to collect real-time images of melting edge state changes of ingredients at the bottom of the kiln. During the collection process, the cooling component can continuously reduce the impact of the external temperature on the thermal imaging camera through cold water; and the purge component can blow the ingredients attached to the camera inside the kiln back into the kiln.

[0043] S102, analyzing and processing the collected images; illustratively, during the image collection process, the image of the melting edge state change of the ingredient is fed back to the control device according to the setting of transmitting once every five seconds, and the control device processes and analyzes the received multiple batches of the image of the melting edge state change of the ingredient.

[0044] S103. Marking state changes in the processed images; illustratively, during the processing, the melting edge of the ingredients on each image is marked by punctuation, and then the distance of the marked point from the rear of the pool bottom is calculated, and the distance changes on each image are compared. While comparing, the comparison data, comparison time, change in the distance of the marked point, and change in the image color of each image are displayed on the large screen in the monitoring room. The production management personnel judge the change in the state of the melting edge of the ingredients based on the change in the distance of the marked points and the change in the image color on each displayed image, adjust the feeding frequency of the feeding mechanism in real time, and accurately control the production links.

[0045] This detection method has changed the previous method of controlling the moving speed and temperature of the molten materials, which relied on the calculation of the plate weight and thickness, which was labor-intensive and difficult to find hidden dangers in time. By monitoring the melting edge state of the molten materials, the edge position of the molten materials is marked through image analysis software, and the temperature is distinguished by different colors. The moving speed of the edge of the molten materials and the temperature changes can be observed intuitively. The equipment cost is low and the economic benefits are high. It is an advanced technology in the full technical field of kiln process control.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit its protection scope. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in the field should understand that after reading the present invention, those skilled in the art can still make various changes, modifications or equivalent substitutions to the specific implementation methods of the invention, but these changes, modifications or equivalent substitutions are all within the protection scope of the pending claims of the invention.
