[0058] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0059] Embodiment 1:

[0060] Combination Figures 1 to 3 As shown, an embodiment of the present invention provides a feeding control method for a pin-type nano sand mill, comprising:

[0061] S1, calibrate the sensor component in the pin-type nano sand mill, and obtain the initial distribution state of the material to be ground in the grinding barrel through the sensor component; the sensor component includes an angle sensor and a pressure sensor.

[0062] In the first step of the control method, the purpose is to ensure that the system correctly reflects the initial distribution of the material in the grinding barrel. The process involves calibrating and testing the sensor, so that all subsequent adjustments and optimizations will be based on the data provided by the sensor at this moment; a correctly calibrated sensor can accurately capture the distribution of the material and provide a reliable starting point for subsequent operations. This step not only optimizes the accuracy of the sensor readings, but also sets a benchmark for the effective operation of the sand mill.

[0063] S2, start the air flow homogenization system to provide orderly air flow into the grinding barrel, and set the operating parameters of the air flow homogenization system according to the initial distribution state of the material to be ground in the grinding barrel to adjust the air flow state of the orderly air flow; the air flow homogenization system is equipped with an adjustable damper and a built-in fan, and the air flow parameters of the internal air flow are adjusted according to the real-time distribution data of the material in the grinding barrel to reduce the material segregation and stratification caused by aerodynamic effects. Among them, the air flow parameters include air flow speed and air flow direction.

[0064] Start and adjust the air flow homogenization system so that the orderly air flow it generates can be effectively adjusted according to the initial distribution state of the material in the grinding barrel. The adjustment of the air flow state here is to optimize the distribution of the material and prevent segregation or stratification problems caused by aerodynamic effects. The adjustment of air flow parameters depends on the data obtained by the calibrated sensor to ensure that the air flow passes through the material with low resistance and promotes uniform contact between the grinding medium and the material.

[0065] S3, start the metering and conveying device to feed the grinding barrel according to the preset feeding plan, obtain the distribution state of the material to be ground after the orderly airflow optimization through the sensor component to optimize the preset feeding plan, and execute the optimized feeding plan to feed the grinding barrel one by one.

[0066] Combined with the optimized material distribution state monitored by the sensor, this step dynamically adjusts the preset feeding plan of the metering and conveying device, and adjusts it according to the actual situation during the entire feeding process. By executing the optimized feeding plan, it is ensured that the material enters the grinding barrel evenly, creating ideal conditions for the grinding process and ensuring the continuity and consistency of the grinding process.

[0067] S4, during the feeding process, the real-time distribution information of the ground material in the grinding barrel is obtained through the sensor component, and the real-time distribution information is fed back to the central processing unit. The central processing unit analyzes the uniformity of the ground material based on the particle size distribution standard, and adjusts the operating parameters of the air flow homogenization system and the feeding plan of the metering and conveying device to maintain the optimal material supply state.

[0068] Real-time feedback and optimization loop, through continuous monitoring of the real-time distribution of materials in the grinding barrel, through the data captured by the sensor components, the central processor analyzes the uniformity of the material and adjusts the air flow homogenization system and metering and conveying device accordingly; this closed-loop control mechanism realizes the integration of on-site monitoring and immediate adjustment, ensuring the maintenance of the optimal material supply state. It can adjust the operating parameters according to real-time data to continuously keep the feeding and grinding process in the best state.

[0069] The working principle of the present invention is as follows: the initial distribution state of the material in the grinding barrel is calibrated and acquired by using the sensing component, the baseline of the material at the beginning of feeding is created, the airflow homogenization system is started, and the airflow parameters are set according to the initial material distribution state to adjust the orderly airflow in the grinding barrel so as to promote the uniform distribution of the material; then the metering and conveying device is started, and the preset feeding plan is adjusted according to the material distribution state to ensure that the material is fed one by one according to the optimized feeding plan to maintain the uniform distribution; during the feeding process, the real-time distribution of the material is continuously monitored by the sensing component, and the information is fed back to the central processing unit in real time, and the central processing unit analyzes the uniformity of the material and adjusts the airflow homogenization system and the metering and conveying device accordingly to maintain the optimized feeding state; through the feeding control method, the rod-pin type nano sand mill realizes the continuous monitoring of the distribution of the material to be ground in the hopper, so that the ground material can maintain the best uniformity in the whole feeding process, realizes the dynamic adjustment and real-time optimization of the supply of the ground material, avoids the segregation and stratification problems caused by the aerodynamic effect in the feeding system, improves the controllability of the grinding process, and can significantly improve the grinding efficiency and the quality consistency of the product.

[0070] In this embodiment, the specific description is that step S1 specifically includes:

[0071] S11, start the pin-type nano sand mill and preheat it so that the grinding barrel reaches a preset working temperature; to stabilize the environment inside the grinding barrel and reduce the influence of thermal expansion and contraction on the accuracy of the sensor.

[0072] The startup and preheating operation of the pin-type nano sand mill is designed to make the inside of the grinding barrel reach an operating temperature suitable for the grinding process. The preheating process ensures that the temperature of the machine is stable before starting grinding. The temperature stability also helps to reduce variables caused by thermal expansion of the material, thereby ensuring the accuracy and consistency of the sensor readings.

[0073] S12, executing a self-diagnosis sequence to detect the operating status of the sensor component and determine the response speed of the sensor component; the sensor component includes an angle sensor, a pressure sensor and an infrared particle size analyzer. Executing a self-diagnosis program to check the operating status and response time of the sensor component to ensure that key data of the grinding process can be captured in a timely and accurate manner.

[0074] It should be noted that in the pin-type nano sand mill, the angle sensor is installed at a position associated with the rotating spindle of the grinding barrel to measure the rotation angle of the rotating spindle of the grinding barrel, so as to monitor the rotation speed and position of the grinding barrel. In this way, the shear force on the material and the frequency of interaction between the grinding medium and the material can be understood.

[0075] The pressure sensor is installed on the inner wall of the grinding barrel to capture the pressure changes caused by the interaction between the material and the grinding medium to sense the filling degree and distribution density of the material in the grinding barrel.

[0076] The infrared particle size analyzer is set at the sampling port on the grinding barrel. It determines the particle size distribution by measuring the scattering or absorption of infrared light in the material. It is used to monitor the particle size distribution of the material in real time and help determine whether the grinding has achieved the required fineness and uniformity.

[0077] It is further explained that the specific process of analyzing the distribution status of the grinding material through the detection data of the sensor component is as follows: the rotation speed and position information are obtained from the angle sensor, the pressure sensor provides the data of the material density and filling status, the infrared particle size analyzer provides the particle size distribution information, and the central processing unit fuses the detection data of these sensor components to analyze the overall distribution status of the material in the grinding barrel. The overall distribution status includes the uniformity of distribution, the degree of grinding and the dynamic behavior of the material in the grinding barrel.

[0078] In this embodiment, it is further explained that after step S12, the following steps are further included:

[0079] S13, using a standard ball applied to an empty grinding barrel, sending a detection signal toward each preset detection point, obtaining an initial reading of the sensor component at the working temperature, so as to evaluate the detection signal coverage and signal reception quality of the internal space of the grinding barrel; wherein the detection signal is infrared.

[0080] Evaluate the detection signal coverage and quality in the grinding barrel by sending the detection signal into the grinding barrel without the material to be ground. Using a standard ball can calibrate the signal and test the feedback effect of the system, ensuring that the sensor signal covers the required range and the reception quality meets the requirements before starting grinding, which is the basis for monitoring the material distribution.

[0081] S14, optimizing the position and angle of the sensor assembly according to the obtained detection signal coverage and signal reception quality of the empty grinding barrel, so as to ensure effective monitoring of the distribution of the material to be ground.

[0082] Adjust and optimize the position and angle of the sensor components according to the data collected in the steps to ensure the comprehensiveness and efficiency of the monitoring system; proper sensor positioning is crucial for the comprehensiveness and accuracy of signal acquisition, ensuring that the sensor can capture accurate material distribution data throughout the grinding barrel. The optimized sensor deployment is conducive to collecting more accurate and representative data, providing effective information support for the next step of material supply and grinding process control.

[0083] S15, loading the grinding barrel with the material to be ground, operating the sensor component to monitor the filling and distribution of the material to be ground in the grinding barrel, and obtaining the initial distribution state of the material to be ground in the grinding barrel according to the feedback signal of the sensor component.

[0084] Loading the material to be ground into the grinding barrel and starting the sensor component to monitor the filling and distribution of the material is a preliminary monitoring step after the actual loading of the material to obtain the initial distribution state of the material before grinding. By monitoring the actual loaded material, accurate initial distribution data can be obtained, providing important benchmark information for the subsequent optimization of the airflow homogenization system and feeding planning. It also provides verification for the optimization adjustment of the sensor position and angle before verification.

[0085] In this embodiment, the specific description is that step S2 specifically includes:

[0086] S21, analyzing the initial distribution state of the material to be ground in the grinding barrel, and identifying the area where the material is unevenly distributed;

[0087] Careful analysis of the initial distribution of the material to be ground inside the grinding barrel is intended to identify areas where the material distribution is uneven, i.e. areas of uneven material distribution. This can help identify potential problem areas, which can affect grinding efficiency and product quality. By evaluating the initial distribution of the material, the subsequent airflow homogenization strategy can be adjusted more precisely and targeted, thereby improving the overall performance of the grinding process.

[0088] S22, according to the identified uneven material distribution area, the fan speed and damper opening in the air flow homogenization system are set to formulate an initial air flow pattern, so as to specifically alleviate the material distribution problem in the uneven area.

[0089] According to the uneven material distribution area obtained from the step analysis, the air flow homogenization system is adjusted, including the fan speed and the damper opening, to establish an initial air flow pattern. By adjusting these air flow parameters, the air flow conditions in the grinding barrel can be finely controlled to optimize the uneven material distribution area in a targeted manner. This process enables the air flow homogenization system to better adapt to the actual material distribution conditions, thereby providing a more uniform grinding environment for the material.

[0090] S23, running the initial airflow mode, providing orderly airflow into the grinding barrel through the airflow homogenization system.

[0091] The air flow homogenization system starts working, providing orderly airflow into the grinding barrel according to the customized parameter settings, correcting the problem of uneven material distribution areas identified previously, thereby promoting the uniform spreading of the material to be ground; stable and orderly airflow can effectively prevent material aggregation and segregation, and provide better contact opportunities for the grinding medium with the material, which helps to improve grinding efficiency and ensure the quality consistency of the final product.

[0092] In this embodiment, it is further explained that after step S23, the following steps are further performed:

[0093] S24, based on the distribution information fed back by the sensor component after the initial airflow mode is run, the fluid dynamics simulation software carried by the central processor is used to simulate the distribution state of the material by the orderly airflow in real time, and the effect of the current operating parameters is evaluated based on the simulated material distribution state;

[0094] Guided by the information collected by the sensor components on the influence of orderly airflow on the material distribution state, the fluid dynamics simulation software integrated in the central processor is used to simulate the interaction between airflow and material in real time. This simulation can predict the possible results of material distribution under different airflow parameter settings. Using this simulated feedback, the actual impact of the current airflow setting on the material distribution state can be evaluated, which helps to understand more carefully how different airflow patterns affect the behavior of materials and make more informed adjustment decisions.

[0095] S25, adjusting the operating parameters of the airflow homogenization system according to the effects of the operating parameters to optimize the initial airflow pattern;

[0096] Through the information collected through simulation analysis and feedback data, the operating parameters of the air flow homogenization system are further adjusted to optimize the initial air flow pattern. This process involves fine-tuning the fan speed, changing the opening of the damper or adjusting the air flow direction, etc. Its goal is to optimize the air flow to achieve the ideal state of material distribution. The real-time evaluation and adjustment process ensures that the system outputs uniform, high-quality and orderly airflow, improving grinding efficiency and output quality.

[0097] S26, operating the adjusted operating parameters of the airflow homogenization system to adjust the airflow state of the ordered airflow.

[0098] The parameter settings of the air flow homogenization system are adjusted and the air flow pattern is adjusted to produce a new orderly air flow state, which is predicted to provide better grinding conditions based on the previous simulation analysis and actual material distribution feedback. During the initial loading grinding stage, the system can continuously monitor and quickly respond to the need to optimize material distribution to ensure that operating conditions are always maintained at the best state.

[0099] In this embodiment, the specific description is that step S3 specifically includes:

[0100] S31, start and set the metering and conveying device to start the initial material feeding process to the grinding barrel according to the preset feeding plan;

[0101] The metering conveyor is set to operate according to a preset feeding plan to start the initial feeding process of the grinding barrel material. The preset feeding plan involves setting parameters such as material conveying speed, feeding time and vibration frequency of the hopper to meet the established feeding requirements. Correctly setting the metering conveyor is the basis for ensuring that the material enters the grinding barrel at the appropriate rate and amount.

[0102] S32, during the initial feeding process, using a sensor component to detect the distribution state of the material to be ground after orderly airflow optimization;

[0103] Use sensor components to monitor in real time the material distribution status that has been optimized by orderly airflow to ensure whether the airflow adjustment measures are effective, and monitor the actual distribution of materials in the grinding barrel. Through the feedback information of the sensor components, it can be determined whether the material is evenly laid and whether the airflow setting or feeding plan needs to be adjusted.

[0104] S33, according to the distribution status provided by the sensor component, confirm whether the distribution is uniform as expected, if so, continue to execute the preset feeding plan, and start the optimization process to adjust the preset feeding plan;

[0105] Evaluate and confirm the distribution of the material. By analyzing the data provided by the sensor components, it can be determined whether the material distribution has reached the expected uniformity standard. If the material is unevenly distributed, this step will activate the optimization process to adjust the preset feeding plan to solve the uneven distribution problem and then continue the feeding process in the best state.

[0106] S34, during the optimization process, the preset feeding plan is modified by the feeding calculation model built into the central processing unit, and the optimal values ​​of key feeding parameters such as material feeding speed and hopper vibration frequency are calculated to obtain the optimized feeding plan;

[0107] The optimization process is carried out to fine-tune the preset feeding plan. The feeding calculation model in the central processor is used to evaluate and calculate key feeding parameters, such as material feed rate and hopper vibration frequency, in order to find the most optimized feeding solution. The optimization process is an iterative data-driven method that uses intelligent algorithms to adjust the feeding plan according to actual conditions to ensure the continuity and efficiency of material supply.

[0108] It should be noted that the feeding calculation model is an embedded algorithm of the central processing unit, which can calculate and optimize the parameters of the feeding planning based on the sensor data; among them, the preferred one is the particle swarm optimization algorithm.

[0109] S35, applying the optimal value of the optimized feeding plan to the metering and conveying device, and feeding the grinding barrel by a step-by-step feeding method.

[0110] After the optimized feeding plan is obtained, the calculated optimal feeding parameters are set to the metering and conveying device so that the material can be added to the grinding barrel in an optimized manner. Through metering and feeding control, this step helps ensure that the material can maintain a stable and uniform distribution during the grinding process.

[0111] In this embodiment, the specific description is that step S4 specifically includes:

[0112] S41, during the feeding process, the real-time distribution information of the grinding material in the grinding barrel is obtained through the sensor component, and the real-time distribution information is fed back to the central processor.

[0113] The sensor component obtains the distribution information of the material in the grinding barrel in real time. The continuous monitoring mechanism ensures that the grinding process can respond to the changes in material distribution in real time and adjust the operation in time to maintain the grinding efficiency and product quality. The data provided by the sensor component will be fed back to the central processor in real time, and the feedback mechanism allows the system computing core to understand the actual operation status.

[0114] S42, the central processing unit receives the real-time distribution information of the grinding material in the grinding barrel monitored by the sensor component, and maps the real-time distribution information into a material particle size distribution diagram to accurately grasp the current uniformity level of the grinding material.

[0115] By converting sensor data into a graphical representation, the central processor is able to quickly identify and understand any potential distribution problems, providing technicians with a clearer and more intuitive basis for action.

[0116] S43, comparing the material particle size distribution diagram with a preset particle size distribution standard, identifying deviation areas that deviate from the particle size distribution standard through image processing and data analysis technology, and calculating the degree of deviation of each deviation area.

[0117] Combined with the material particle size distribution map, analysis and evaluation are performed according to the set standards, and image processing and data analysis technology are used to determine the deviation areas in the material distribution. By comparing the real-time distribution map with the preset particle size distribution standard, the system can confirm which areas have deviations and further calculate the degree of deviation in these areas. Accurately measuring the deviation of each area can provide a quantitative basis for further adjustment decisions to optimize the grinding process.

[0118] In this embodiment, it is further explained that after step S43, the following steps are further included:

[0119] S44, based on the position and degree of deviation of the deviation area, the central processing unit calculates the airflow state required for adjusting the corresponding deviation area, adjusts the operating parameters of the airflow homogenization system according to the required airflow state, and converts the adjusted operating parameters into a first control instruction to adjust the fan speed and damper opening of the airflow homogenization system; so as to change the airflow speed, direction and pressure in the grinding barrel, and accurately optimize the area that deviates from the standard.

[0120] The identified distribution deviation is adjusted accordingly. The central processor calculates the airflow state that needs to be adjusted according to the specific location and degree of deviation of each deviation area, and then converts these data into the first control instruction to adjust the airflow homogenization system, including the parameters of fan speed and damper opening. The accuracy of this step directly affects the optimization effect of material distribution. Therefore, the calculation of the required airflow state and the conversion into control instructions must be highly accurate to ensure that the adjusted airflow can effectively improve the material distribution in the deviation area.

[0121] S45, the central processing unit calculates the average distribution of the grinding material in the grinding barrel as a whole according to the deviation degree of all deviation areas, and adjusts the feeding plan of the metering and conveying device according to the average distribution to control the inflow rate and distribution pattern of the material; wherein the adjustment range of the feeding plan includes the vibration frequency of the hopper, the conveying speed of the conveying member, and the opening and closing degree of the hopper gate;

[0122] The central processor combines information from all deviation areas to calculate the overall average distribution of the ground material in the grinding barrel, which covers all deviations in the process and takes into account their overall impact. Then, based on the average distribution, the metering and conveying device feeding plan is adjusted to optimize the material inflow rate and distribution pattern, which includes adjusting parameters such as the hopper vibration frequency, the conveying speed of the conveyor, and the opening and closing degree of the hopper gate, with the aim of ensuring that the material is supplied to the grinding barrel in the best state.

[0123] S46, in the successive feeding processes, the current real-time distribution information is re-obtained for each feeding process, and the operating parameters of the airflow homogenization system and the feeding plan of the metering and conveying device are adjusted again.

[0124] The system will implement an iterative optimization cycle to ensure continuous improvement of the grinding process. During the feeding process, the system will continuously collect new real-time distribution information and adjust the settings of the air flow homogenization system and the metering conveying device based on the latest information. Among them, the interval between each feeding process provides the interval for calculation and adjustment. This continuous monitoring and adjustment process ensures that the parameters of the air flow and feeding planning are always optimized according to the latest grinding status, thereby improving grinding efficiency and ensuring the quality of the final product.

[0125] In this embodiment, it is further explained that after step S4, the following steps are further included:

[0126] S5, analyzes the particle size information of the ground material through the visual inspection module and evaluates the operating status of the air flow homogenization system and the metering and conveying device.

[0127] The visual inspection module analyzes the particle size of the grinding material, providing an evaluation basis for evaluating the operating effect of the air flow homogenization system and the metering and conveying device. By comparing with the preset particle size parameters, the visual inspection module can accurately assess whether the grinding efficiency and the output quality have reached the expected standards. This process not only enables operators to understand the current production status in a timely manner, but also provides important feedback information for further adjustment and optimization of the grinding process. Through this subsequent evaluation method, the performance of the pin-type nano sand mill can be continuously monitored and improved.
