[0027] In the glass manufacturing industry, the production of optical glass has almost strict requirements on product quality due to its key applications in many high-tech fields. From precision optical instruments to high-end electronic device display screens, the performance stability and uniformity of optical glass directly determine the quality and performance of the end product. In this complex production process, liquid level control is a crucial part of the glass melting link, which is like a precision hub in the production chain, and the stability of the liquid level is directly related to the quality of the product.

[0028] Liquid level control is a typical complex control object in the field of industrial control. On the one hand, it widely involves multiple industrial control levels, covering multiple links from physical sensor measurement to logical control algorithm execution. On the other hand, liquid level control has the characteristics of high nonlinearity and hysteresis. Its nonlinearity is that the relationship between liquid level change and control input is not a simple proportional relationship, but is influenced by many complex factors, such as the flow characteristics of glass liquid, uneven temperature distribution inside the furnace, etc. Hysteresis means that there is a certain time delay in the response of the liquid level after the control action is implemented, which further increases the difficulty of control. Although the conventional PID control method performs well in many linear control systems, it is often difficult to achieve ideal control effect when facing these complex characteristics of liquid level control.

[0029] At present, the industry generally adopts a control method based on manual smelting experience. This method puts high requirements on the professional quality and practical experience of employees. The operator needs to rely on long-term accumulated experience to judge the liquid level state and make manual adjustments. However, manual control has many inherent defects. The operator is prone to fatigue during long-term continuous monitoring and adjustment, which not only leads to excessive labor intensity, but also seriously affects the consistency and accuracy of control. At the same time, the experience of different operators is significantly different, which makes the control effect uneven, and it is difficult to ensure the accuracy and stability of the liquid level control. In the background of modern industrial production emphasizing efficiency, stability and high precision, this manual control method obviously cannot meet the production needs.

[0030] In summary, how to improve the stability of liquid level control, ensure that the liquid level remains accurate and stable during the glass smelting process, and thus ensure the high-quality production of optical glass products, has become a key problem that needs to be solved in the glass manufacturing industry.

[0031] Therefore, the present application provides a glass liquid level control method, which can be referred to Figure 1 , Figure 1 is a process of a glass liquid level control method provided by an embodiment of the present application. The glass liquid level control method can be applied to any terminal device that can run a program.

[0032] Hereinafter, a glass liquid level control method according to an embodiment of the present application will be described in detail. Figure 1

[0033] Step S101: Collect the real-time liquid level height of the target pipeline, and calculate the real-time liquid level difference between the real-time liquid level height and the target liquid level height.

[0034] The target pipeline is a pipeline connecting the discharge port of the melting pool and the feed port of the electric furnace refining pool. For example, the target pipeline can be an MF pipe, a quartz glass pipe or other specially designed composite material pipeline. In actual application, the target pipeline can be an ultrahigh temperature (such as >1300℃) pipe pool for transmitting liquid glass. Optionally, the target pipeline can be divided into multiple sections according to the actual liquid level control requirements, and the liquid level of each section of the pipeline is independently controlled by the glass liquid level control method proposed in the present application.

[0035] For example, the real-time liquid level height of the target pipeline is collected by a pre-installed laser sensor, the measured real-time liquid level height at a certain time is 548mm, the target liquid level height is 550mm, and the real-time liquid level difference between the real-time liquid level height and the target liquid level height is 2mm obtained by calculation.

[0036] ​The difference value reflects the deviation of the current liquid level from the target liquid level, and is one of the important bases for subsequent judgment of the liquid level state and decision of temperature adjustment. If the real-time liquid level difference value is positive, it means that the liquid level is lower than the target liquid level; if it is negative, it means that the liquid level is higher than the target liquid level; the absolute value of the difference value reflects the deviation degree, and the larger the absolute value, the more serious the deviation. In the whole production process, the control system repeatedly carries out the above acquisition and calculation steps, continuously monitors the change of the liquid level height, and provides real-time data support for subsequent liquid level control.

[0037] Step S102: Obtain the liquid level change trend of the target pipeline in a preset time period. The liquid level change trend is used to represent the change trend of the difference value between the actual liquid level height and the target liquid level height.

[0038] Obtaining the liquid level change trend of the target pipeline in the preset time period is to analyze the difference value between the actual liquid level height and the target liquid level height in the preset time period, and determine the liquid level change trend. The liquid level change trend is used to represent the change trend of the difference value between the actual liquid level height and the target liquid level height, and the liquid level change trend can be rising or falling.

[0039] It should be understood that the length of the determined preset time period should be able to reflect the short-term change trend of the liquid level, and cannot be too long to cause lag in response to the change of the liquid level.

[0040] In an optional embodiment, before obtaining the liquid level change trend of the target pipeline in the preset time period, the method further comprises: obtaining a plurality of liquid level heights in the preset time period, the plurality of liquid level heights being used to represent the liquid level heights at different times in the preset time period; calculating a plurality of liquid level difference values between the plurality of liquid level heights and the target liquid level height respectively; and determining the liquid level change trend according to the change law of the plurality of liquid level difference values with time.

[0041] When obtaining the plurality of liquid level heights in the preset time period, the terminal device periodically acquires liquid level data points in the preset time period at a fixed time interval. For example, the fixed time interval is 10 seconds.

[0042] Exemplarily, the preset time period is 10 minutes before the time corresponding to the real-time liquid level height of the target pipeline, and it is assumed that 60 liquid level height values are collected in the 10 minutes, and the liquid level collection period (10 seconds) is denoted as H1, H2, H3,..., H60, respectively. It is known that the target liquid level height is 550 mm. The liquid level difference between each liquid level height and the target liquid level height is calculated, for example, the first liquid level difference AH1 = 550 - H1, the second liquid level difference AH2 = 550 - H2, and so on, to obtain 60 liquid level differences AH1, AH2,..., AH60. Taking time as the independent variable x and the liquid level difference as the dependent variable y, 60 data points (x1, y1), (x2, y2),..., (x60, y60) are constructed, and the least square method is used to linearly fit the data points. The fitting straight line equation is y = kx + b, the slope k and the intercept b of the straight line are calculated according to the least square method formula, and the liquid level change trend is determined according to the calculated slope k. When the least square method is used to fit the straight line y = kx + b, the distance between all data points and the straight line is the error e. For each data point (x i , y i )(x i is the collection time, and y i is the liquid level difference), the error e i =y i -(k x i +b), and the total error . The parameters of the slope k and the intercept b are solved, k , and b , where n is the number of data points. According to the sum of n natural numbers: and the sum of n squares of natural numbers: , when n = 60, =1830, =73810. Substitute and into the equation about k and b to obtain 73810k + 1830b = -10000 and 1830k + 60b = -300, and the solution is k = -0.02 and b = 5. Because k < 0, the liquid level changes in the direction higher than the target liquid level and gradually approaches the target liquid level, that is, the liquid level shows an upward trend, and according to the absolute value, the liquid level rises slowly. In this application, when the absolute value of k is greater than 0.03, it is considered that the liquid level changes fast, and when the absolute value of k is less than 0.03, it is considered that the liquid level changes slowly.

[0043] If k > 0, it indicates that the liquid level difference increases with time, that is, the liquid level changes in the direction lower than the target liquid level and deviates more and more, and it can be determined that the liquid level shows a downward trend. The absolute value of k reflects the speed of the liquid level change, and the greater the absolute value, the faster the change.

[0044] In this embodiment, the liquid level difference value reflects the deviation of the liquid level at each moment from the target liquid level, and the variation rule of the difference value over time is analyzed to determine the liquid level change trend, so that the liquid level change trend can more accurately represent the dynamics of the liquid level change in the preset period, and a more reliable basis is provided for determining the preset temperature adjustment value.

[0045] In an optional embodiment, before obtaining the plurality of liquid level coordinates in the preset period, the method further comprises: emitting a plurality of laser beams with different frequencies to the glass liquid level surface at a preset acquisition period in the preset period; receiving a plurality of laser signals reflected by the plurality of laser beams; comparing the plurality of laser signals with a plurality of preset reflection signals to obtain a plurality of phase differences formed by the plurality of laser signals and the plurality of preset reflection signals; and calculating a plurality of liquid level heights according to the plurality of phase differences and a plurality of frequencies corresponding to the plurality of laser beams.

[0046] Before the laser sensor emits a plurality of laser beams with different frequencies to the glass liquid level surface, a specially designed mounting bracket can be provided, which has adjustable angle and position functions. During installation, the technician will determine the appropriate installation height and angle by measuring and calculating according to the specific structure and size of the glass furnace or container, so that the laser beam can be directly pointed to the expected liquid level surface area; the laser sensor can also be equipped with aiming auxiliary devices such as optical sights or laser pointers. During the initial installation and debugging stage, the operator can adjust them to be exactly aligned with the liquid level surface, which is not limited in this application.

[0047] The preset reflection signal is a reflection signal measured in advance under the condition of a known standard liquid level height and the same emission condition.

[0048] In combination with the above example, the laser liquid level meter emits a plurality of laser beams (3) with different frequencies to the glass liquid level surface every 10S within 10 minutes, such as the frequencies of the plurality of laser beams are f1, f2, f3, according to experience and accuracy requirements, the liquid level height values corresponding to f1, f2, f3 are assigned weights w1, w2, w3 (for example, w1=0.2, w2=0.3, w3=0.5), at the same time, the receiving device of the laser liquid level meter receives a plurality of laser signals reflected by the plurality of laser beams from the glass liquid level surface, compares each received laser signal with the corresponding preset reflection signal, and calculates the phase difference Δφ1 (corresponding to f1), Δφ2 (corresponding to f2), Δφ3 (corresponding to f3) formed by the laser signal and the preset reflection signal; according to the principle of laser phase comparison, the formula (wherein L is the liquid level height, c is the speed of light, Δφ is the phase difference, and f is the laser frequency) to calculate the liquid level height L1, L2, and L3 corresponding to each time point, and then the liquid level height at each time point is L = L1 x w1 + L2 x w2 + L3 x w3.

[0049] In this embodiment, different frequency laser beams are emitted based on the properties of the glass liquid level surface (such as high temperature and viscosity), and the liquid level height is calculated using the phase difference, so that the liquid level height data with high accuracy can be obtained, and reliable data source for determining the liquid level change trend is provided.

[0050] Step S103: According to the change trend and the real-time liquid level difference, a corresponding preset temperature adjustment value is matched from the preset temperature adjustment strategy, so as to adjust the temperature value of the target pipe according to the preset temperature adjustment value.

[0051] The preset temperature adjustment strategy sets a corresponding preset temperature adjustment strategy for the combination of different liquid level difference ranges and liquid level change speeds (judged by the k value). The preset temperature adjustment strategy can be generated by comprehensively considering the relevant liquid level adjustment experience (such as expert experience) and the standard set temperature adjustment strategy. For example, when the real-time liquid level difference is 1-3mm and the absolute value of k is less than 0.03, the preset temperature adjustment value is-0.5℃.

[0052] Exemplarily, after obtaining the real-time liquid level difference of 2mm and the parameter k =-0.02, since the absolute value of k is less than 0.03, it indicates that the liquid level change speed is slow and in the rising trend, according to this information, the preset temperature adjustment strategy is queried and matched, the matching result is that the preset temperature adjustment value is-0.5℃, and then the temperature of the target pipe is lowered by 0.5℃.

[0053] Since the temperature of the pipe directly affects the viscosity of the liquid glass, thereby indirectly controlling the flow of the liquid glass, the present application proposes that by calculating the difference between the real-time liquid level height of the target pipe and the target liquid level, combined with the analysis of the liquid level change trend in the preset period, the change trend of the liquid level can be dynamically and carefully mastered, it is predicted whether the liquid level is close to or far from the target liquid level, and the speed of the change, and then the temperature of the target pipe is adjusted in time according to these information, so as to realize the dynamic adjustment of the glass liquid level in the pipe pool, and further improve the stability of the glass liquid level control.

[0054] In an optional embodiment, after the corresponding preset temperature adjustment value is matched from the preset temperature adjustment strategy according to the change trend and the real-time liquid level difference, and the temperature value of the target pipe is adjusted according to the preset temperature adjustment value, the method further comprises: acquiring a calibration temperature of the target pipe, determining a corresponding glass liquid flow value of the target pipe according to the calibration temperature, the calibration temperature being a temperature value at any time after the temperature value of the target pipe is adjusted according to the preset temperature adjustment value; acquiring a calibration liquid level, judging a correction liquid level trend corresponding to the calibration liquid level according to the glass liquid flow value, the calibration liquid level being a liquid level at any time after the temperature value of the target pipe is adjusted according to the preset temperature adjustment value; matching a corresponding preset correction temperature adjustment value from the preset temperature adjustment strategy according to the correction liquid level trend and the calibration liquid level; calculating the preset correction temperature adjustment value based on a preset weight value to obtain a correction temperature adjustment value, so as to adjust the temperature value of the target pipe again according to the correction temperature adjustment value.

[0055] The calibration temperature is a temperature value at any time after the temperature value of the target pipe is adjusted according to the preset temperature adjustment value. The temperature value at any time can be 10 min after the temperature value of the target pipe is adjusted, or 5 s, which can be set by the staff according to actual needs. It is easy to understand that the calibration liquid level refers to a liquid level value collected at any time, which can be collected at the same time as the calibration temperature or within the adjacent time range of the time when the calibration temperature is collected, which is not limited in the present application.

[0056] The preset weight value is set based on the relative importance of the pipe in flow control. It is assumed that the pipe connecting the discharge port of the melting tank and the feed port of the electric furnace refining tank is divided into three sections, MF1, MF2 and MF3. The weight of MF1 pipe is 50%, the weight of MF2 pipe is 30%, and the weight of MF3 pipe is 20%. The target pipe can be any one of MF1, MF2 and MF3. If the pipe connecting the discharge port of the melting tank and the feed port of the electric furnace refining tank is not segmented, the target pipe is the pipe connecting the discharge port of the melting tank and the feed port of the electric furnace refining tank, and the weight is 1.

[0057] Taking the target pipe MF1 as an example, the real-time temperature of MF1 obtained by the temperature sensor is 1075℃, and the preset temperature adjustment value is -2℃. The expected temperature value is 1075℃-2℃×50%=1074℃. The glass liquid flow value is calculated according to the characteristics of the target pipe and the related formula (flow Q∝K×T, K is a system constant determined by the characteristics of the target pipe, and T is the temperature of the MF pipe). For example, K=0.008, and the glass liquid flow value Q=0.008×1074=8.592 Then, the temperature value of the target pipe is adjusted according to the corresponding relationship between the glass liquid flow value and the temperature adjustment strategy in the preset temperature adjustment strategy. For example, the glass liquid flow value is 8.592 The glass liquid flow value and the actual pipeline flow value are compared to determine the change amount of the pipeline flow, and if the change amount corresponds to a liquid level height that deviates from the target, the target pipeline temperature value is further adjusted, such as being reduced by 0.5°C again.

[0058] In this embodiment, by introducing the calculation and analysis of real-time temperature, expected temperature value and glass liquid flow value, the temperature can be more accurately adjusted according to the pipeline flow feedback, and the liquid level control effect is further optimized.

[0059] In an alternative embodiment, according to the change trend and the real-time liquid level difference value, a corresponding preset temperature adjustment value is matched from a preset temperature adjustment strategy to adjust the temperature value of the target pipeline according to the preset temperature adjustment value, including: obtaining a first temperature value corresponding to the change trend, and matching a corresponding first temperature adjustment value from the preset temperature adjustment strategy; obtaining a second temperature value corresponding to the real-time liquid level difference value, and matching a corresponding second temperature adjustment value from the preset temperature adjustment strategy; calculating the sum of the first temperature adjustment value and the second temperature adjustment value to obtain a third temperature adjustment value, and calculating a corresponding preset temperature adjustment value based on a preset thermal inertia coefficient and the third temperature adjustment value.

[0060] For example, when the liquid level change trend (such as a slope k = 0.03, the liquid level shows a faster rising trend) and the real-time liquid level difference value (assuming 3 mm) are determined, the first temperature value corresponding to the change trend is obtained, and according to a large number of past experiments and production experience, the first temperature value is -1.5°C under this faster rising trend, which aims to suppress the rapid rise of the liquid level, and the first temperature adjustment value corresponding to -1.5°C is -1.1°C; and the second temperature value -0.9°C corresponding to the real-time liquid level difference value 3 mm is obtained, and the second temperature adjustment value corresponding to -0.9°C is -1.3°C, which aims to compensate for the liquid level deviation; the sum of the first temperature adjustment value and the second temperature adjustment value is calculated to obtain a third temperature adjustment value, i.e. -1.1 + (-1.3) = -2.4°C. The target pipeline has thermal inertia, which will delay the temperature adjustment effect, and assuming that the preset thermal inertia coefficient is 0.8, the preset temperature adjustment value is calculated to be -2.4 x 0.8 = -1.92°C, and the temperature of the target pipeline is adjusted accordingly.

[0061] In this embodiment, the liquid level change trend and the real-time liquid level difference value are split into corresponding temperature values, and the preset temperature adjustment value is calculated comprehensively, taking into account the influence of pipeline thermal inertia, which can improve the accuracy and scientificity of temperature adjustment.

[0062] In an alternative embodiment, before calculating the initial temperature adjustment value according to the preset thermal inertia coefficient to obtain the preset temperature adjustment value, the method further comprises: obtaining historical temperature adjustment data, the historical temperature adjustment data comprising temperature change data, liquid level change data, and environmental data; calculating change parameters according to the historical temperature adjustment data, the change parameters comprising a temperature change amount, a liquid level change amount, a liquid level change time, an environmental temperature, and a humidity; and inputting the change parameters into a thermal inertia coefficient calculation function to obtain the preset thermal inertia coefficient.

[0063] The temperature change data comprises an initial temperature, an adjusted temperature, and a time required to reach a stable liquid level each time the temperature is adjusted. For example, in one adjustment, the temperature change data comprises an initial temperature of 1000°C, an adjusted temperature of 1020°C, and a time of 60S from starting to adjust the temperature to reaching the stable liquid level.

[0064] The liquid level change data comprises a liquid level change corresponding to the temperature change, comprising an initial value and a stable value of the liquid level. For example, the liquid level change data comprises an initial value of 50CM and a stable value of 52CM of the liquid level.

[0065] The environmental data comprises relevant data in a production environment, such as an environmental temperature and a humidity. It is assumed that the environmental temperature is 25°C and the humidity is Rh=50%.

[0066] Optionally, the thermal inertia coefficient calculation function is , is a temperature change amount, is a liquid level change amount, is a liquid level change time, is an environmental temperature, is a humidity.

[0067] Exemplarily, according to the obtained historical temperature adjustment data, the temperature change amount is calculated (for example, 1000°C-1020°C=20°C), the liquid level change amount (for example, 50CM-52CM=2CM), the liquid level change time is (for example, 60S), the environmental temperature is (for example, 25°C), and the humidity is (for example, 50%), and the preset thermal inertia coefficient is obtained by combining the thermal inertia coefficient calculation function M.

[0068] In this embodiment, the thermal inertia coefficient is calculated by comprehensively considering the temperature, the liquid level, and the environmental elements, so that the thermal inertia coefficient is fitted to the actual working condition.

[0069] In an optional embodiment, before the corresponding preset temperature adjustment value is matched from the preset temperature adjustment strategy according to the change trend and the real-time liquid level difference to adjust the temperature value of the target pipeline, the method further comprises: determining whether the liquid level change trend is in a reasonable change range by the preset temperature adjustment strategy, and if so, the preset temperature adjustment value adjusts the temperature value of the target pipeline.

[0070] In combination with the above example, the liquid level change trend is 0.03, after the liquid level change trend of the target pipeline in the preset period is obtained, it is determined whether the liquid level change trend 0.03 belongs to a safe change trend or a dangerous change trend, if it is a safe change trend, the preset temperature adjustment strategy further comprises determining according to the liquid level change trend, if it is a dangerous change trend, an alarm signal is sent to indicate the staff to handle the dangerous situation in time.

[0071] In this embodiment, by determining whether the liquid level change trend is in a reasonable range, temperature adjustment errors caused by too fast liquid level change can be effectively avoided, thereby avoiding unexpected situations caused by too fast liquid level change.

[0072] Optionally, after the calibration temperature of the target pipeline is obtained, and the corresponding glass liquid flow value of the target pipeline is determined according to the calibration temperature, the method further comprises: calculating a flow difference value between the estimated pipeline flow value and the real-time pipeline flow value; determining whether the flow difference value is in a reasonable change range, and if so, adjusting the temperature value of the target pipeline according to the temperature adjustment strategy corresponding to the estimated pipeline flow value.

[0073] Exemplarily, after the glass liquid flow value is obtained, the real-time pipeline flow value of the target pipeline is obtained by an electromagnetic flowmeter, assuming that the glass liquid flow value is 8 , the real-time pipeline flow value is 7.8 , and the flow difference value is 8-7.8=0.2 . A reasonable change range is preset, for example, ±0.3 . Since 0.2 is within the reasonable change range, it is determined that the temperature value of the target pipeline can be adjusted according to the preset temperature adjustment value corresponding to the glass liquid flow value. If the flow difference value exceeds this range, it is considered that the temperature adjustment amplitude is too large, and the preset temperature adjustment value needs to be determined again, and the new flow difference value corresponding to the newly determined preset temperature adjustment value is calculated, and it is determined whether the new flow difference value is reasonable, and if not, the preset temperature adjustment value is continuously adjusted.

[0074] In this embodiment, by calculating the difference between the glass liquid flow value and the real-time pipeline flow value and determining whether it is in a reasonable range, the accuracy of the estimated flow can be effectively verified, and temperature adjustment errors caused by too large estimation deviation can be avoided.

[0075] In order to better understand the scheme proposed in this application, this application is illustrated in combination with actual application scenarios. Please refer to the content shown in the figure, including the melting pool, the laser liquid level meter, the linkage control box, the liquid level difference calculation, the temperature control cabinet, the connecting pipes 1, 2, 3…, the HMI human-machine interface, the clarification pool, etc. The following is a detailed description of each part Figure 2

[0076] Melting pool: This is the starting position of glass melting. The glass raw materials are melted here to form liquid glass. For example, various raw materials are put into the melting pool in a certain proportion and gradually melted into liquid state under high temperature environment to provide glass liquid for the subsequent process.

[0077] Liquid level collection: The laser liquid level meter is arranged near the melting pool to collect liquid level information. It works in a predetermined manner, for example, it emits laser beams of different frequencies (such as 3 beams of different frequencies) to the surface of the glass liquid every 10 seconds within 10 minutes. Assuming that the frequencies of these beams are f1=100Hz, f2=200Hz, f3=300Hz, and according to experience and accuracy requirements, they are assigned weights w1=0.2, w2=0.3, w3=0.5 respectively. The laser liquid level meter receives multiple laser signals reflected from the glass liquid surface, compares each received laser signal with the corresponding preset reflection signal, and calculates the phase difference formed by the laser signal and the preset reflection signal. According to the principle of laser phase comparison and related formulas, the corresponding liquid level height L1, L2, L3 at each time is calculated, and the final liquid level height at each time is L= L1×w1+L2×w2 + L3×w3.

[0078] Liquid level difference calculation: Assuming that the target liquid level height is 550mm, and the multiple liquid level height values collected by the laser liquid level meter are H1=548mm, H2=549mm, H3=549.5mm, etc. Then calculate the first liquid level difference ΔH1=550-H1=2mm, the second liquid level difference ΔH2=550-H2=1mm, the third liquid level difference ΔH3=550-H3=0.5mm, etc.

[0079] ​Liquid level change trend determination: With time as the independent variable x and liquid level difference as the dependent variable y, multiple data points (x1, y1), (x2, y2), (x3, y3) are constructed, such as (10s, 2mm), (20s, 1mm), (30s, 0.5mm). Linear fitting is performed on these data points using the least squares method, and the fitting straight line equation is y = kx + b. According to the least squares formula, the slope k and intercept b of the straight line are calculated. Suppose k = -0.02 and b = 5 are calculated. Because k < 0, the liquid level is changing in the direction of being higher than the target liquid level and gradually approaching the target liquid level, that is, the liquid level is in an upward trend, and according to the absolute value of the slope, the liquid level rises slowly.

[0080] Temperature adjustment strategy formulation: The linkage control box matches the corresponding preset temperature adjustment value from the preset temperature adjustment strategy according to the liquid level change trend and the liquid level difference. The preset temperature adjustment strategy sets corresponding preset temperature adjustment strategies for different combinations of liquid level difference ranges and liquid level change speeds (judged by k value). For example, when the real-time liquid level difference is 1-3mm and the absolute value of k is less than 0.03, the preset temperature adjustment value is -0.5℃. In the above example, the real-time liquid level difference is 2mm, 1mm, 0.5mm, etc., and k = -0.03, which meets the conditions, so according to this information, the preset temperature adjustment strategy is queried and matched, and the matching result is that the preset temperature adjustment value is -0.5℃.

[0081] Temperature control cabinet: According to the instructions of the linkage control box, the temperature of the connecting pipe is controlled. For example, if the linkage control box determines to lower the temperature of the connecting pipe by 0.5℃, the temperature control cabinet will perform corresponding operations to reduce the pipe temperature. By adjusting the temperature, the viscosity of the liquid glass can be changed, thereby affecting the flow rate and liquid level height of the glass liquid. Assuming that the initial temperature of the connecting pipe is 1000℃, after being lowered by 0.5℃, it becomes 999.5℃, the viscosity of the glass liquid will increase accordingly, thereby affecting its flow speed and liquid level height in the connecting pipe.

[0082] Connecting pipe 1, 2, 3…: used to transport liquid glass, connecting the melting tank, refining tank and other related equipment.

[0083] HMI human-machine interface: provides an interface for operators to interact with the system, through which operators can view the running status of the system, such as liquid level height, temperature value, etc., and also can set and adjust some parameters. For example, the operator can view the current liquid level height as 549.5mm and the connecting pipe temperature as 999.5℃ on the HMI human-machine interface, and also can modify the target liquid level height, temperature adjustment strategy and other parameters according to actual situation.

[0084] Refining Tank: Liquid glass enters the refining tank through a connecting pipe from the melting tank, where it undergoes further clarification to make the molten glass purer. For example, physical or chemical methods are used in the refining tank to remove impurities from the molten glass, thereby improving the quality of the glass.

[0085] Glass molten flow: This represents the flow path of molten glass in the system, starting from the melting pool, passing through the connecting pipe, entering the refining pool, and finally being discharged for forming. It visually illustrates the transmission process of molten glass throughout the system.

[0086] Heating control: Associated with the temperature control cabinet, it is responsible for controlling the various parts that require heating (such as connecting pipes, melting pools, and other heating equipment) to ensure that the temperature meets process requirements. For example, the heating control will heat or stop heating the connecting pipes according to the instructions of the temperature control cabinet to maintain their temperature within a suitable range.

[0087] Molding: This is the final stage of glass production. After a series of previous processes, the molten glass is shaped into its final product form here. For example, the molten glass is poured into a mold and cooled to form glass products of specific shapes, such as lenses or glass tubes.
