[0002] At present, the development of the glass manufacturing industry is inseparable from the efficient kiln melting process. The melting rate directly affects the competitiveness and market position of the enterprise. In recent years, with the advancement of automation technology, more and more glass manufacturers have begun to explore automated control methods in order to break the limitations of traditional manual control and further tap the production potential of kilns.
[0003] The production capacity of glass product manufacturers is determined by the size of the kiln area. When the area of the kiln is certain, if you want to increase the production capacity, you can only do so by increasing the melting rate. The melting rate refers to the amount of qualified glass liquid melted per square meter of the kiln every 24 hours, and the unit is (tons / day. square meter). All glass factories will increase the kiln melting rate as a goal to improve production efficiency and increase economic benefits. Therefore, there is still room for improvement. Summary of the invention
[0004] In order to solve the problem of low melting rate of current kilns, the present application provides a control method, device, equipment and storage medium for improving the melting rate of kilns.
[0005] The above-mentioned invention objective of the present application is achieved through the following technical solutions: A control method for improving the melting rate of a kiln, the control method for improving the melting rate of a kiln comprising: Acquire the kiln heating temperature in real time, and acquire the heating element identification and the element output power corresponding to each heating element identification according to the kiln heating temperature; Compare the real-time heating temperature of the kiln with the preset temperature curve, adjust the output power of each element according to the comparison result, and obtain the kiln temperature control result; Obtaining the current pressure in the furnace, and performing calculations based on the current pressure in the furnace to obtain a furnace pressure adjustment instruction; After obtaining the furnace pressure regulation result of the furnace pressure regulation instruction, a furnace gas dynamic switching instruction is generated according to the furnace pressure regulation result to respond to the glass preparation instruction.
[0006] By adopting the above technical solution, the melting rate of the kiln can be significantly improved, and production efficiency and economic benefits can be improved. Specifically: by pre-installing multiple high-precision temperature sensors, the heating temperature in the kiln is monitored in real time, which not only ensures the accuracy of the temperature data, but also provides reliable data support for subsequent temperature control adjustments. By obtaining the kiln heating temperature in real time, the system can timely capture the changing trend of the kiln temperature and provide an accurate reference for subsequent temperature control; by analyzing the real-time kiln heating temperature data, the identification of each heating element is automatically identified, and the output power corresponding to each heating element is obtained, and fine control can be performed on different heating areas to ensure uniform temperature distribution of the entire kiln, thereby improving the melting effect; by presetting an idealized temperature curve, the real-time kiln heating temperature can be compared with the preset temperature curve to quickly identify the The deviation between the actual temperature and the ideal temperature is detected, and the output power of each heating element is adjusted accordingly, so that the furnace temperature is always in the optimal melting range, thereby effectively improving the melting rate; by pre-installing a pressure sensor, the pressure change inside the furnace is monitored in real time. According to the current pressure in the furnace, the appropriate air pressure adjustment instruction can be calculated to maintain the stability of the pressure inside the furnace, which not only avoids the uneven melting caused by pressure fluctuations, but also improves the operation stability of the furnace and extends the service life of the equipment; after completing the air pressure adjustment, the corresponding gas dynamic switching instruction will be generated to meet various needs in the glass preparation process. For example, during the reversing process, the system will adjust the natural gas, secondary air and kiln pressure in advance to ensure a smooth transition of various parameters and avoid interruptions in the melting process. This dynamic switching mechanism not only improves production efficiency, but also ensures the consistency of product quality. In summary, by adopting the above technical solution, it is possible to achieve all-round intelligent control of furnace temperature, air pressure and gas flow, significantly improve the melting rate of the furnace, optimize production efficiency, reduce energy consumption, and improve economic benefits.
[0007] In a preferred example, the present application can be further configured as follows: comparing the real-time heating temperature of the kiln with a preset temperature curve, adjusting the output power of each element according to the comparison result, and obtaining the kiln temperature control result, specifically including: Obtaining a furnace heating interval from the temperature curve, and obtaining a temperature median from the furnace heating interval; The median temperature and the kiln heating temperature are input into the following formula to obtain the kiln temperature control result: Among them, P(t) is the temperature control result of the kiln, K p , K i and K d are the corresponding proportional coefficient, integral coefficient and differential coefficient respectively, and the T set is the median temperature, and T(t) is the heating temperature of the kiln.
[0008] By adopting the above technical solution, the real-time kiln heating temperature is compared with the preset temperature curve, and the output power of each heating element is adjusted according to the comparison result, so that more precise and accurate temperature control can be achieved; first, the furnace heating range is extracted from the preset temperature curve, and the median temperature is obtained from it. This median temperature is used as a reference point for comparison with the real-time measured kiln heating temperature to evaluate whether the current kiln temperature state meets expectations. Next, the median temperature and the kiln heating temperature are input into a specific control algorithm formula. Through this formula, the output power of each heating element can be dynamically adjusted so that the kiln temperature can quickly and accurately return to the preset temperature curve, which not only improves the accuracy of temperature control, but also greatly reduces the energy waste caused by temperature fluctuations. Through automated temperature control strategies, the kiln temperature can be kept stable under various working conditions, thereby significantly improving the melting rate of the kiln. In addition, this technical solution can effectively extend the service life of the kiln. Frequent temperature fluctuations will accelerate the aging and damage of kiln materials, and through refined temperature control, this negative impact can be minimized. A stable temperature environment also helps to improve product quality, reduce the defective rate, and thus improve overall production efficiency and economic benefits.
[0009] In a preferred example, the present application can be further configured as follows: the current pressure in the furnace is obtained, and calculation is performed according to the current pressure in the furnace to obtain the furnace pressure adjustment instruction, specifically including: Obtain the preset furnace constant pressure data, input the current furnace pressure into the following formula to obtain the exhaust port opening adjustment target value: O(t)=H·(Y set -Y(t)), where (O(t) is the exhaust port opening adjustment target value, H is the preset gain coefficient, and Y set is the constant pressure data in the furnace, and Y(t) is the current pressure in the furnace; The current exhaust port opening data is obtained, and the furnace pressure adjustment instruction is calculated according to the current exhaust port opening data and the exhaust port opening adjustment target value.
[0010] By adopting the above technical solution, the melting rate of the kiln can be effectively improved and the stability of the internal pressure of the kiln can be maintained. Specifically: by obtaining the current pressure in the furnace and comparing it with the preset constant pressure data, the required exhaust port opening adjustment target value can be accurately calculated through the formula, and the change of the pressure in the furnace can be quickly responded to and the exhaust port opening can be adjusted in time to ensure that the internal pressure of the kiln is always maintained within the ideal range. This not only helps to maintain the stable operation of the kiln, but also effectively avoids melting interruptions caused by pressure fluctuations, further improving production continuity and product quality.
[0011] In a preferred example, the present application can be further configured as follows: after obtaining the furnace pressure adjustment result of the furnace pressure adjustment instruction, generating a furnace gas dynamic switching instruction according to the furnace pressure adjustment result to respond to the glass preparation instruction, specifically including: Acquire kiln fuel data, and calculate a preset nonlinear function according to the kiln fuel data, wherein the nonlinear function includes a natural gas consumption function and a secondary air content function; The current natural gas consumption and secondary air content are obtained, and the current natural gas consumption, the secondary air content and the nonlinear function are input into the following formula to obtain the target value of natural gas consumption and the target value of secondary air content: Q gas (t)=f(T(t),Y(t)),R air (t) = g(Q gas (t),T(t),Y(t)), where Q gas is the target value of natural gas consumption, R air is the secondary air content target value, f() is the natural gas consumption function, and g() is the secondary air content function; according to the difference between the natural gas consumption target value and the current natural gas consumption, and the difference between the secondary air content target value and the secondary air content, the dynamic switching instruction of the furnace gas is generated.
[0012] By adopting the above technical solution, the furnace heating temperature is obtained in real time and the output power of each heating element is adjusted according to the preset temperature curve, which can effectively maintain the furnace temperature within the ideal range, thereby improving the melting rate; at the same time, by obtaining the current furnace pressure in real time and calculating the furnace pressure adjustment instruction, and then adjusting the exhaust port opening, the internal pressure of the furnace can be maintained stable to avoid the melting process being affected by pressure fluctuations; on this basis, the furnace fuel data is further obtained, and the preset nonlinear function is calculated based on the furnace fuel data, and then the current natural gas consumption and secondary air content are obtained, and the current natural gas consumption, secondary air content and nonlinear function are input into the corresponding formula to calculate the natural gas consumption target value and secondary air content target value. This process makes full use of the current furnace pressure obtained when adjusting the exhaust port opening, and dynamically adjusts the natural gas consumption and secondary air content in combination with the actual situation of the kiln to ensure full combustion of the fuel, reduce heat energy waste, and further improve melting efficiency; finally, based on the difference between the natural gas consumption target value and the current natural gas consumption, as well as the difference between the secondary air content target value and the current secondary air content, a dynamic switching instruction for the gas in the furnace is generated to ensure a smooth transition of various parameters during the switching process, avoid interruptions in the melting process, and ensure continuous and efficient production. The above technical solution can not only achieve precise control of the kiln temperature, pressure and gas flow, but also can be flexibly adjusted under different working conditions, significantly improving the melting rate of the kiln, and improving production efficiency and economic benefits.
[0013] In a preferred example, the present application can be further configured as follows: the obtaining of the current natural gas consumption and secondary air content specifically includes: Acquire external humidity data, and compare the external humidity data with a preset humidity reference value to obtain humidity change conditions; When the humidity change exceeds a preset value, a ventilation adjustment instruction is triggered to obtain the current natural gas consumption and the secondary air content.
[0014] By adopting the above technical solution, in the specific steps of obtaining the current natural gas consumption and secondary air content, the monitoring and comparison of external humidity data are introduced, which can more accurately reflect the impact of actual environmental changes on the melting process of the kiln; through the integrated meteorological station or humidity sensor, the humidity data of the external environment is monitored in real time, which not only takes into account the temperature and pressure inside the kiln, but also extends to external environmental factors, making the entire control system more comprehensive and intelligent; by real-time monitoring of the external humidity, the possible impact of environmental changes on the melting process of the kiln can be discovered in time, so that measures can be taken in advance to make adjustments; after obtaining the external humidity data, it is compared with the preset humidity reference value to obtain the humidity change. When the humidity change exceeds the preset value, the ventilation adjustment instruction will be automatically triggered, and the current natural gas consumption and secondary air content will be recalculated to ensure that the two can still achieve the optimal combustion effect under the new humidity conditions, thereby ensuring the efficient operation of the kiln: after recalculating the target values of natural gas consumption and secondary air content, the system will generate a dynamic switching instruction for the gas in the furnace according to the difference between these target values and the current actual values. This instruction will guide the various components of the kiln (such as solenoid valves, fans, etc.) to make corresponding adjustments to ensure that the flow of natural gas and secondary air can quickly reach the new target value. Through this dynamic adjustment, the system can ensure that the kiln is always in the optimal combustion state under different humidity conditions, thereby ensuring the stability and improvement of the melting rate. In summary, by introducing the monitoring and comparison of external humidity data, the system can more accurately reflect the impact of external environmental changes on the melting process of the kiln, and by triggering ventilation adjustment instructions and recalculating natural gas consumption and secondary air content, ensure that the kiln can maintain an efficient operating state under various humidity conditions, significantly improving the melting rate and production efficiency of the kiln.

According to the current pressure in the furnace, the appropriate air pressure adjustment instruction can be calculated to maintain the stability of the pressure inside the kiln, which not only avoids the uneven melting caused by pressure fluctuations, but also improves the operation stability of the kiln and extends the service life of the equipment; after completing the air pressure adjustment, the corresponding gas dynamic switching instruction will be generated to meet various needs in the glass preparation process. For example, during the switching process, the system will adjust the natural gas, secondary air and kiln pressure in advance to ensure a smooth transition of various parameters and avoid interruptions in the melting process. This dynamic switching mechanism not only improves production efficiency, but also ensures the consistency of product quality.
