Description

Technical Field

[0001] This invention relates to the field of energy-saving pulverizer technology, specifically to an energy-saving phospholipid raw material pulverizer and system. Background Technology

[0002] Phospholipid raw materials include soybean phospholipids and egg yolk phospholipids, which are mostly in the form of blocks, granules, or pastes before being pulverized. Pulverization is necessary to adapt them to subsequent production processes. This includes improving the extraction efficiency of the main chemical components of phospholipids and subsequent purification, as well as ensuring the uniformity of mixing phospholipids with other excipients. Pulverized phospholipid raw materials, due to their characteristics of "uniform particle size, good activity retention, and ease of processing," are widely used in various fields such as food, medicine, cosmetics, and animal feed.

[0003] The common process for pulverizing phospholipid raw materials involves using a pulverizing blade assembly. Therefore, the proper feeding of phospholipid raw materials and the control of the blade spacing are crucial for the normal operation of the pulverizing process and for ensuring pulverization accuracy.

[0004] Currently, when pulverizing phospholipid raw materials using a pulverizing blade assembly, a fixed blade spacing is used. However, due to the influence of the phospholipid raw material input, the phospholipid particles to be pulverized vary considerably. Although a fixed blade spacing can produce phospholipid particles of the target size, uncrushable phospholipid accumulates on the blade assembly and cannot fall, thus failing to pass through the filter and enter the storage bin. If this phenomenon is too severe, a large number of particles will remain unpulverized, blocking subsequent pulverization processes. Furthermore, the continued input of phospholipid raw material makes the entire pulverization process uncontrollable, severely affecting the normal pulverization process and pulverization accuracy of the phospholipid raw material. Therefore, it is necessary to adjust the blade spacing in the phospholipid raw material pulverization process and simultaneously implement adaptive control of the phospholipid raw material input. Summary of the Invention

[0005] To address the technical problem of adaptively controlling the feeding of phospholipid raw materials and the blade spacing, the present invention aims to provide an energy-saving phospholipid raw material pulverizer and system, the specific technical solution of which is as follows: In a first aspect, embodiments of the present invention provide an energy-saving phospholipid raw material pulverizer, including a pulverizer body, the pulverizer body further including a pulverizing system, the pulverizing system being installed on the pulverizer body, the pulverizing system including: a sensor module, a pulverizing control mechanism and a blade group monitoring and analysis controller; The signal output terminal of the sensor module is connected to the signal input terminal of the blade group monitoring and analysis controller, and the signal output terminal of the blade group monitoring and analysis controller is connected to the signal input terminal of the crushing control mechanism. The crushing control mechanism is used to adjust the valve opening and the blade group spacing. The sensor module is used to acquire the material quantity data of phospholipid raw materials in the storage hopper of the crusher and the blade current of the crushing blade assembly, and output them to the blade assembly monitoring and analysis controller. The blade assembly monitoring and analysis controller is used to determine the crushing capacity of the crusher by analyzing material quantity data and the accumulation of phospholipid raw materials; to determine the raw material retention coefficient by comparing the retention of phospholipid raw materials in the current feeding stage and the previous feeding stage; to determine the crusher's variable parameters by comparing the crushing capacity and the raw material retention coefficient in the current feeding stage and the previous feeding stage; to determine the load coefficient by analyzing the amplitude and variation of the blade assembly current in the current feeding stage and the previous feeding stage; and to determine the actual processing parameters by combining the crusher's variable parameters and the load coefficient. When the actual processing parameters and the load coefficient meet a first condition, the blade spacing of the crushing blade assembly is determined using the actual processing parameters. When the actual processing parameters and the load coefficient meet a second condition, the valve opening is determined using the valve opening change ratio and the crusher's variable parameters. When the actual processing parameters do not meet the first and second conditions, the valve opening and blade spacing are determined using the crushing capacity and the raw material retention coefficient. Based on the valve opening and blade spacing, control commands are output to the crushing control mechanism to adjust the valve opening and blade spacing.

[0006] Furthermore, the determination of the pulverizing capacity of the pulverizer by analyzing material quantity data and based on the accumulation of phospholipid raw materials includes: The material quantity data includes the qualified processing amount of phospholipid, the amount of phospholipid added, the total amount of crushed material, and the degree of phospholipid accumulation; wherein the total amount of crushed material is the sum of the weight in the temporary storage bin and the storage bin; the method for obtaining the degree of phospholipid accumulation is as follows: the difference between the amount of phospholipid added and the total amount of crushed material is used as the numerator, the amount of phospholipid added is used as the denominator, and the ratio formed by the numerator and the denominator is used as the degree of phospholipid accumulation. Calculate the ratio of qualified phospholipid treatment amount to phospholipid dosage, and use it as the phospholipid treatment ratio; The pulverizing capacity of the pulverizer is obtained by combining the phospholipid treatment ratio and the phospholipid accumulation degree; wherein, the phospholipid treatment ratio is positively correlated with the pulverizing capacity, and the phospholipid accumulation degree is negatively correlated with the pulverizing capacity.

[0007] Furthermore, the determination of the raw material retention coefficient by comparing the retention status of phospholipid raw materials in the current delivery stage and the previous delivery stage includes: For any dosing stage, the dosing retention ratio is determined by using the difference between the amount of phospholipid added and the amount of phospholipid that has been treated as the numerator and the amount of phospholipid added as the denominator. The raw material retention coefficient is determined by combining the retention ratio of the current and previous stages and the degree of phospholipid accumulation in the previous stage.

[0008] Furthermore, the step of comparing the crushing capacity and raw material retention coefficient of the crusher in the current feeding stage and the previous feeding stage to determine the changing parameters of the crusher includes: The ratio of the crushing capacity of the crusher in the previous feeding stage to that in the current feeding stage is used as the processing ratio. The ratio of the raw material retention coefficient in the current feeding stage to that in the previous feeding stage is calculated and used as the raw material retention ratio. By combining the processing ratio and the raw material retention ratio, the changing parameters of the pulverizer are obtained, wherein both the processing ratio and the raw material retention ratio are positively correlated with the changing parameters of the pulverizer.

[0009] Furthermore, the determination of the load factor by analyzing the amplitude and variation of the knife group current in the current deployment phase and the previous deployment phase includes: Analyze the amplitude change of the blade current during the feeding phase of the crusher to determine the load change rate; Analyze the load change of the crusher at the beginning of the current feeding phase to determine the initial change rate; The load coefficient is determined by combining the load change rate and initial change rate of the current deployment phase and the previous deployment phase.

[0010] Furthermore, determining the actual processing parameters for the previous feeding stage by combining the changing parameters of the crusher and the load coefficient includes: By combining the data fluctuations of the pulverizer's changing parameters, load coefficient, and blade current, the actual processing parameters are obtained. The data fluctuations of the pulverizer's changing parameters, load coefficient, and blade current are all positively correlated with the actual processing parameters.

[0011] Furthermore, determining the blade spacing of the shredder assembly using actual processing parameters includes: The actual processing parameters are subjected to negative correlation normalization mapping, and the result value after negative correlation normalization mapping is used as the adjustment coefficient; the adjustment coefficient is used as the weight to weight the blade spacing in the current deployment stage to obtain the blade spacing in the next deployment stage.

[0012] Furthermore, determining the valve opening degree by the valve opening degree change ratio and the pulverizer change parameters includes: Calculate the ratio of valve opening degree in the current deployment stage to that in the previous deployment stage, and use it as the valve opening degree change ratio; The parameters of the crusher are subjected to negative correlation normalization mapping, and the result of the negative correlation normalization mapping is used as the initial adjustment coefficient. By combining the initial adjustment coefficient and the valve opening change ratio, the valve adjustment coefficient is obtained; Using the valve adjustment coefficient as a weight, the valve opening in the current deployment stage is weighted to obtain the valve opening in the next deployment stage, wherein the valve opening is limited to between 0-100%.

[0013] Furthermore, determining the valve opening and blade spacing based on the crushing capacity and raw material retention coefficient includes: The opening adjustment coefficient is determined based on the crushing capacity and the raw material retention coefficient; When the raw material retention coefficient is less than or equal to the preset accumulation threshold, the valve opening in the current delivery stage is weighted by the positively correlated normalized mapping opening adjustment coefficient to obtain the valve opening in the next delivery stage. Using the negative correlation normalized mapping opening adjustment coefficient as the weight, the blade spacing in the current deployment stage is weighted to obtain the blade spacing in the next deployment stage. When the raw material retention coefficient is greater than the preset accumulation threshold, the valve opening in the current delivery stage is weighted by the negative correlation normalized mapping opening adjustment coefficient to obtain the valve opening in the next delivery stage.

[0014] Secondly, an energy-saving phospholipid raw material pulverizing system is provided, comprising the following modules: The accumulation analysis module is used to determine the crushing capacity of the crusher by analyzing material quantity data and the accumulation of phospholipid raw materials; and to determine the raw material retention coefficient by comparing the retention of phospholipid raw materials in the current feeding stage and the previous feeding stage.

The intelligent control module is used to determine the blade spacing of the crushing blade group based on the actual processing parameters when the actual processing parameters and load coefficient meet the first condition; to determine the valve opening based on the valve opening change ratio and the crusher change parameters when the actual processing parameters and load coefficient meet the second condition; and to determine the valve opening and blade spacing based on the crushing capacity and the raw material retention coefficient when the actual processing parameters do not meet the first and second conditions.

[0015] Thirdly, embodiments of the present invention provide an electronic device, including a memory and a processor, wherein the memory stores executable code, and when the processor executes the executable code, it implements the various possible implementations of the first aspect.

[0016] Fourthly, embodiments of the present invention provide a computer program product comprising: computer program code, which, when executed on a computer, causes the computer to perform the method described in the first aspect or any possible implementation thereof.

[0017] Fifthly, embodiments of the present invention provide a computer-readable storage medium having a computer program stored thereon, which, when executed in a computer, causes the computer to perform the various possible implementations of the first aspect.

[0018] The embodiments of the present invention have at least the following beneficial effects: This invention first analyzes the crushing capacity and raw material retention coefficient of the crusher. The crushing capacity reflects the efficiency of the crusher in crushing phospholipid raw materials, while the raw material retention coefficient reflects the accumulation of phospholipid raw materials in the crusher. Then, data from the current feeding stage and the previous feeding stage are compared to obtain the actual processing parameters of the previous feeding stage. Considering that there may be some accumulation in the crushing process during historical feeding stages, leading to interference with the current feeding amount and blade spacing, the operating status of the device is compared and analyzed between the two operating states to improve the accuracy of parameter determination and control precision. Based on the conditions satisfied by the actual processing parameters and load coefficient, the valve opening and blade spacing are adaptively controlled. Through closed-loop control of the blade spacing and the valve opening for feeding, the judgment of feeding is improved by adjusting the blade spacing and opening, thus improving the accuracy of crushing and feeding amount judgment. Simultaneously, an adaptive crushing process for phospholipid raw materials is achieved, improving crushing efficiency and crushing precision. Furthermore, feedback on raw material feeding is provided based on the crushing results to achieve closed-loop control. Attached Figure Description

Detailed Implementation

[0021] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description, in conjunction with the accompanying drawings and preferred embodiments, details the specific implementation, structure, features, and effects of an energy-saving phospholipid raw material pulverizer and system proposed according to the present invention.

[0022] In the following description, different "one embodiment" or "another embodiment" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics in one or more embodiments may be combined in any suitable form.

[0023] In the description of the embodiments of the present invention, unless otherwise stated, " / " means "or". For example, A / B can mean A or B. The "and / or" in the text is merely a description of the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist simultaneously, and B exists alone. In addition, in the description of the embodiments of the present invention, "multiple" means two or more.

[0024] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0026] The embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art will recognize that, with technological advancements and the emergence of new scenarios, the technical solutions provided by the embodiments of the present invention are also applicable to similar technical problems.

[0027] This invention provides a specific implementation method for an energy-saving phospholipid raw material pulverizer and system, which is applicable to pulverizers used for pulverizing phospholipid raw materials.

[0028] The energy-saving phospholipid raw material pulverizer disclosed in this invention consists of the following equipment: Phospholipid raw material storage tank: Linked to the conveying equipment via a bottom discharge valve, it provides a stable and quantitative flow of raw materials for subsequent drying processes. The feed rate into the storage tank can be controlled, for example, by adjusting the opening of the discharge valve. This ensures the precise acquisition of a fixed quantity of phospholipid raw materials to be dried.

[0029] Vacuum desiccant: Low temperature prevents oxidation of unsaturated fatty acids in phospholipids, and vacuum isolates air, ensuring the purity of the subsequently pulverized product; after drying, the material has uniform hardness and good flowability, avoiding increased energy consumption and incomplete pulverization caused by wet material adhering to the pulverizing chamber. This achieves the acquisition of dried phospholipid raw materials.

[0030] The pulverizing unit employs a high-efficiency, energy-saving motor and a pulverizing blade assembly or a toothed disc pulverizer to pulverize the dried phospholipid raw materials. A filter screen is then used to filter and screen the phospholipid particles to meet the required particle size. This process achieves the acquisition of phospholipid powder that meets the specified particle size requirements.

[0031] Metal detector: Accurately detects metal fragments that may be mixed in during the crushing process, analyzes the composition of the crushed material, prevents metal impurities from entering subsequent processes, prevents equipment wear or substandard final products, and ensures compliance with food-grade or pharmaceutical-grade phospholipid production standards. Achieves the production of qualified phospholipid powder free of metal impurities.

[0032] Sealing machine: This machine uses heat sealing to isolate the phospholipid granules that meet the requirements from air and moisture. Because powder has a large surface area and easily absorbs moisture, this prevents the pulverized phospholipid powder from absorbing moisture and clumping. This achieves the packaging of sealed phospholipid powder. When using polyethylene bags for heat sealing, the temperature is 120-150℃; when using aluminum-plastic bags, the temperature is 150-180℃.

[0033] The pulverization process of phospholipid raw materials is the core process of the pulverization treatment, specifically as follows: (1) Check the sealing of the top feed port cover of the storage tank, and the bottom discharge valve opens and closes flexibly without leakage; pour the purchased crude phospholipid raw material into the storage tank through the top feed port. The feed amount of each storage tank shall not exceed 80%, about 40 tons / tank, and leave room for expansion. During the feeding process, use a vibrating screen to filter out large impurities in the raw material, such as stones or plastics.

[0034] (2) When the dryer needs to be fed, open the discharge valve at the bottom of the storage tank and start the screw conveyor to dry the material.

[0035] (3) Open the feed hopper gate of the dryer and introduce the raw material conveyed by the screw conveyor into the dryer hopper. A certain amount of raw material is needed for subsequent crushing. The phospholipid raw material is conveyed at a speed of 1 ton per hour, and the conveying speed is controlled by the valve opening.

[0036] (4) The phospholipid raw materials in the dryer hopper are crushed by the crushing unit, and the crushed particles are filtered through the filter screen. The qualified phospholipid particles are stored in the storage hopper, which is located at the bottom of the crushing chamber. At the same time, the filter screen is cleaned in real time, and the cleaned raw materials are stored in the temporary storage hopper, which needs to be further crushed.

[0037] The energy-saving phospholipid raw material pulverizer provided in this embodiment of the invention includes a pulverizer body and a pulverizing system installed on the pulverizer body. The pulverizing system is used to detect and analyze the pulverizing situation of the pulverizer. Therefore, the pulverizing system includes: a sensor module, a pulverizing control mechanism, and a blade group monitoring and analysis controller. The sensor module is connected to the blade group monitoring and analysis controller, which is used for data processing and machine control. The chip type is FPGA, which receives information from the sensor module and controls the pulverizing control mechanism.

[0038] The signal output terminal of the sensor module is connected to the signal input terminal of the blade assembly monitoring and analysis controller, and the signal output terminal of the blade assembly monitoring and analysis controller is connected to the signal input terminal of the crushing control mechanism. The crushing control mechanism is used to adjust the valve opening and the blade assembly spacing.

[0039] The sensor module is used to acquire data on the amount of phospholipid raw material in the hopper of the crusher and the current of the crushing blade assembly.

[0040] Obtain material quantity data of phospholipid raw materials in the storage hopper of the crusher. The material quantity data includes qualified phospholipid processing volume, phospholipid feeding volume, total crushing volume, and phospholipid accumulation degree.

[0041] A weight sensor is installed at the bottom of the hopper of the crusher to monitor the current qualified amount of phospholipid in the hopper; this qualified amount of phospholipid is the weight of the phospholipid particles after crushing.

[0042] The current phospholipid dosage is obtained by detecting the dosage flow rate of phospholipid raw materials. The current of the pulverizing blade assembly is monitored by a current sensor and recorded as the blade assembly current. The blade assembly current reflects the load status of the pulverizing blade assembly during the pulverization of phospholipid raw materials. In this embodiment of the invention, the sampling frequency of the blade assembly current is 1Hz.

[0043] The following description, in conjunction with the accompanying drawings, details the specific solution of the energy-saving phospholipid raw material crusher and system provided by the present invention.

[0044] Please see Figure 1 The diagram illustrates a pulverizing system block diagram of an energy-saving phospholipid raw material pulverizer according to an embodiment of the present invention. The system includes the following modules: The accumulation analysis module 10 is used to determine the crushing capacity of the crusher by analyzing the material quantity data and the accumulation of phospholipid raw materials; and to determine the raw material retention coefficient by comparing the retention of phospholipid raw materials in the current feeding stage and the previous feeding stage.

[0045] Calculate the sum of the weights of the temporary storage bin and the storage bin to obtain the total grinding volume. Calculate the difference between the amount of phospholipid added and the total grinding volume to obtain the accumulated amount of phospholipid. This accumulated amount represents the phospholipid that was not filtered on the grinding blade assembly, and this accumulated phospholipid may block subsequent grinding processes.

[0046] The degree of phospholipid accumulation is determined by using the amount of phospholipid accumulation as the numerator and the amount of phospholipid added as the denominator.

[0047] First, we analyze the pulverizer's processing capacity for phospholipid raw materials. If the qualified processing volume of phospholipids in the current feeding stage is close to the amount of phospholipids added, it indicates that the phospholipid raw materials added through the vacuum dryer during the current pulverization process can be processed, indicating a strong pulverizer processing capacity. The feeding stage is the time period during which phospholipid raw materials are added. However, in actual analysis, some phospholipid raw materials may accumulate in the pulverizer, meaning that phospholipid raw materials added in the previous feeding stage are only processed in the current feeding stage. This means that the difference between the qualified processing volume and the amount of phospholipids added in the current feeding stage does not accurately reflect the true processing situation. Therefore, it is necessary to adjust the valve opening and blade spacing based on the accumulation of phospholipid raw materials on the pulverizer blades.

[0048] By analyzing the material quantity data and the accumulation of phospholipid raw materials, the crushing capacity of the crusher is determined.

[0049] Calculate the ratio of the qualified phospholipid treatment amount to the phospholipid dosage, and use it as the phospholipid treatment ratio.

[0050] The pulverizing capacity of the pulverizer was obtained by combining the phospholipid treatment ratio and the degree of phospholipid accumulation; among them, the phospholipid treatment capacity and the pulverizing capacity were positively correlated, while the degree of phospholipid accumulation and the pulverizing capacity were negatively correlated.

[0051] In some embodiments, the pulverizing capacity of the pulverizer The calculation formula is: Where wf represents the qualified treatment amount of phospholipids; wd represents the amount of phospholipids added. denoted as phospholipid treatment ratio; a represents the degree of phospholipid accumulation; norm is the normalization function, and in this embodiment of the invention, the sigmoid function is selected for normalization.

[0052] In the formula for calculating the crushing capacity, 1-a reflects the phospholipid situation above the crushing blade assembly. The smaller the value of 1-a, the less phospholipid raw material is accumulated, and thus the stronger the crusher's ability to process phospholipid raw material.

[0053] In actual processing, phospholipid raw materials added in the previous stage may still be being processed, thus interfering with the accurate assessment of the pulverizer's processing capacity. Therefore, by analyzing the current processing volume and input volume in the current stage in conjunction with the retention situation in the previous stage, the raw material retention coefficient of the current pulverizer can be obtained.

[0054] For any stage of application, the application-retention ratio is determined by using the difference between the amount of phospholipid applied and the amount of phospholipid that has been treated as the numerator, and the amount of phospholipid applied as the denominator. The application-retention ratio can also be understood as the difference between a constant 1 and the proportion of the treated phospholipid that has been treated as qualified.

[0055] The raw material retention coefficient is determined by combining the retention ratio of the current feeding stage and the previous feeding stage, as well as the degree of phospholipid accumulation in the previous feeding stage. Among them, the retention ratio of the current feeding stage is positively correlated with the raw material retention coefficient; the retention ratio and the degree of phospholipid accumulation in the previous feeding stage are both negatively correlated with the raw material retention coefficient.

[0056] In some embodiments, the raw material retention coefficient The calculation formula is: ;in, This represents the retention rate during the current deployment phase. The retention rate in the previous deployment phase; This represents the degree of phospholipid accumulation in the previous application stage.

[0057] When the raw material retention coefficient is closer to 1, it indicates that the accumulation of phospholipid raw materials is in a stable state, reflecting the processing status of the phospholipid raw materials by the device; when the raw material retention coefficient is less than 1, it indicates that the current feeding stage has effectively resolved the phospholipid raw materials that could not be processed before; when the raw material retention coefficient is greater than 1, it indicates that there is a relatively serious accumulation phenomenon in the current crusher.

[0058] This allows us to obtain the raw material retention coefficient for each feeding stage. The raw material retention coefficient is used to determine whether to transmit the feeding signal for phospholipid raw materials in the feed hopper and the corresponding feeding amount.

[0059] The phase analysis module 20 is used to compare the crushing capacity and raw material retention coefficient of the crusher in the current feeding phase and the previous feeding phase to determine the crusher's changing parameters; by analyzing the amplitude and changes of the blade group current in the current feeding phase and the previous feeding phase, the load coefficient is determined; and by combining the crusher's changing parameters and the load coefficient, the actual processing parameters are determined.

[0060] Besides the amount of phospholipid raw material fed into the machine, the spacing of the pulverizing blades also affects the accumulation of phospholipid raw material. An unreasonable blade spacing can lead to inappropriate pulverization of the phospholipid raw material, affecting the judgment of the actual processing efficiency of the pulverizer. For example, if the blade spacing is too large, the phospholipid raw material will directly enter the storage bin without being pulverized. In this case, the amount of phospholipid fed into the machine will be very close to the amount of phospholipid that can be processed, making the pulverizer appear to have a high processing capacity at the current feeding stage. Furthermore, since there was no phospholipid to be processed in previous feeding stages, this leads to an incorrect judgment of the pulverizer's actual processing capacity. Conversely, if the blade spacing is too small, a large amount of phospholipid raw material will accumulate above the pulverizing blades, preventing normal pulverization and affecting the normal operation of the pulverizer and subsequent phospholipid pulverization.

[0061] Therefore, in this embodiment of the invention, by analyzing the actual crushing process of the pulverizer on phospholipid raw materials, adaptive control of the crushing process is carried out to improve the actual processing capacity and crushing accuracy of the pulverizer.

[0062] By comparing the characteristics of different deployment stages, the actual processing parameters for each deployment stage can be determined.

[0063] First, compare the crushing capacity and raw material retention coefficient of the crusher in the current and previous stages to determine the changing parameters of the crusher, specifically: The ratio of the crushing capacity of the crusher in the previous feeding stage to that in the current feeding stage is used as the processing ratio. The ratio of the raw material retention coefficient in the current feeding stage to that in the previous feeding stage is calculated and used as the raw material retention ratio. By combining the processing ratio and the raw material retention ratio, the changing parameters of the pulverizer are obtained; among them, both the processing ratio and the raw material retention ratio are positively correlated with the changing parameters of the pulverizer.

[0064] In one embodiment of the present invention, the average value of the processing ratio and the raw material retention ratio is used as the pulverizer variation parameters.

[0065] The parameters of the pulverizer change The calculation formula is: ;in, This refers to the crushing and processing capacity of the previous feeding stage; This refers to the current crushing and processing capacity during the initial deployment phase. This represents the raw material retention coefficient during the current deployment phase. This represents the raw material retention coefficient from the previous delivery stage. For processing ratio; This refers to the raw material retention ratio.

[0066] Among them, the processing ratio This reflects the change in the crushing capacity of the crusher between the current and previous feeding stages; the raw material retention ratio. This reflects the change in the raw material retention coefficient of the crusher between the current and previous feeding stages. If the crushing capacity decreases in the current feeding stage, the raw material retention coefficient increases, meaning the crushing capacity in the current feeding stage is less than that in the previous feeding stage, and the corresponding processing ratio increases. Conversely, if the raw material retention coefficient in the current feeding stage is greater than that in the previous feeding stage, the corresponding raw material retention ratio increases. The more normal the crusher's behavior, the greater the corresponding crusher parameter changes. The current and previous feeding stages reflect the changes in the crusher's crushing performance after adjusting the feeding rate.

[0067] The larger the value of the pulverizer's variable parameter, the more it is considered a normal change caused by altering the feed amount; the closer the value of the pulverizer's variable parameter is to 1, the less likely the change in feed amount has any actual impact on the pulverization of phospholipids in the device.

[0068] If the trend characteristics of the current feeding stage are similar to those of the previous feeding stage, it is more likely that the problem is caused by an unreasonable spacing between the crushing blades. If the trend characteristics of the current feeding stage are more clearly different from those of the previous feeding stage, it is a normal phenomenon. If the material is fed evenly during the feeding process, the processing of phospholipid raw materials by the crushing blades will remain stable over time, indicating normal crushing. However, this does not necessarily mean that there is a problem with the blade spacing. In this case, analyzing the blade current in the current feeding stage and the previous feeding stage is crucial. If the blade currents in the two feeding stages are similar, it means that the increase in the feeding amount did not significantly affect the blade current at the end. If the blade current increases, it is a normal crushing phenomenon.

[0069] If it is a normal crushing process, the blade current of the corresponding crushing blade assembly will show an increasing trend with the increase of feed volume. In this embodiment of the invention, the blade current of the crushing blade assembly is the load.

[0070] It should be noted that, since the initial load period is affected by the impact of the loading and cannot reflect the true crushing state, the initial N load data points need to be excluded in subsequent analysis. In this embodiment of the invention, the value of N can be set to 30.

[0071] Therefore, by further analyzing the magnitude and variation of the current in the current distribution phase and the previous distribution phase, the load factor is determined, specifically: The analysis focuses on the amplitude variation of the blade current during the feeding phase of the crusher to determine the load change rate. More specifically, for any feeding phase, the second-order difference of the blade current at two adjacent moments is calculated, and the mean of the second-order difference is used as the trend characteristic value. This allows the acquisition of the trend characteristic values ​​for the previous feeding phase and the current feeding phase. The ratio of the trend characteristic values ​​for the current feeding phase to those for the previous feeding phase is then calculated as the load change rate. It should be noted that the second-order difference calculation of the blade current is used to reflect the amplitude of the blade current change over time.

[0072] Analyze the load change of the crusher at the start of the current feeding stage to determine the initial rate of change. More specifically, calculate the ratio of the blade current at the end of the current feeding stage to that at the end of the previous feeding stage, as the initial rate of change. It should be noted that the end of the previous feeding stage is equivalent to the start of the current feeding stage.

[0073] The load coefficient is determined by combining the load change rate and initial change rate from the current deployment phase and the previous deployment phase. Both the load change rate and the initial change rate are positively correlated with the load coefficient, and the load coefficient is a normalized value.

[0074] Load factor in embodiments of the present invention The calculation formula is: ;in, This represents the trend characteristic value at the current deployment stage; This represents the trend characteristic value of the previous deployment phase; This represents the load change rate. This represents the current of the cutter group at the end of the current deployment phase. This refers to the current of the knife group at the end of the previous deployment phase; α is the initial rate of change; α is the zeroing parameter.

[0075] It should be noted that since this invention analyzes data from a pulverizer undergoing pulverization, the blade current in the previous feeding stage is not zero by default. If the blade current in the previous feeding stage is zero, the intelligent control of the pulverizer will automatically stop and switch to manual control. When the trend characteristic value of the previous feeding stage is zero, α is 1; when the trend characteristic value of the previous feeding stage is not zero, α is 0.

[0076] By combining the data fluctuations of the pulverizer's changing parameters, load coefficient, and blade current, the actual processing parameters of the previous feeding stage are obtained. Among them, the data fluctuations of the pulverizer's changing parameters, load coefficient, and blade current are all positively correlated with the actual processing parameters.

[0077] Specifically, the degree of fluctuation in the blade current was determined by using the standard deviation of the blade current as the measure of its fluctuation. This fluctuation indicates whether the blade current has maintained stability and consistency. Stability suggests that the blade spacing is inappropriate and the added phospholipids have not been properly pulverized.

[0078] In this embodiment of the invention, the actual processing parameter is the normalized value of the product of the data fluctuations of the pulverizer's changing parameters, the load coefficient, and the blade assembly current. The normalization method used in this embodiment of the invention is the sigmoid normalization method.

[0079] The larger the value of this actual processing parameter, the more the previous delivery stage conforms to the actual processing procedure.

[0080] The intelligent control module 30 determines the blade spacing of the crushing blade group based on the actual processing parameters and load coefficient when the actual processing parameters and load coefficient meet the first condition; it determines the valve opening based on the valve opening change ratio and the crusher change parameters when the actual processing parameters do not meet the first and second conditions; and it determines the valve opening and blade spacing based on the crushing capacity and the raw material retention coefficient when the actual processing parameters do not meet the first and second conditions.

[0081] When the actual processing parameter is too small, it is considered to meet the first condition. More specifically, when the actual processing parameter is less than a preset actual judgment threshold and the load coefficient is less than a preset load judgment threshold, it is determined that the first condition is met. In this embodiment of the invention, the preset actual judgment threshold is 95%, and the preset load judgment threshold is 20%.

[0082] When the actual processing parameters and load factor meet the first condition, the blade spacing of the crushing blade assembly is adjusted based on the actual processing parameters. The smaller the actual processing parameters, the more likely the amount of phospholipid raw material added or the blade spacing is inappropriate. In this case, the smaller the load factor of the blade assembly current, the greater the probability that the blade spacing is inappropriate, and the blade spacing needs to be adjusted.

[0083] The smaller the actual processing parameters, the smaller the impact of the newly added feed on the crusher's crushing process. In this case, increasing the blade spacing is necessary to effectively increase the crusher's ability to crush phospholipid raw materials.

[0084] The blade spacing of the crushing blade assembly is adjusted by adjusting the actual processing parameters. Specifically, the actual processing parameters are negatively correlated and normalized, and the result value after negative correlation normalization is used as the adjustment coefficient. The blade spacing of the current feeding stage is weighted using the adjustment coefficient as the weight to obtain the blade spacing of the next feeding stage.

[0085] In some embodiments, the blade group spacing in the next delivery phase The calculation formula is: ;in, For actual processing parameters; This represents the blade spacing during the current deployment phase.

[0086] Then, the phospholipids in the temporary storage bin are returned to the feed hopper for reprocessing, and the feed volume in the feed hopper is restored to the level of the previous feeding stage, that is, the valve opening of the previous feeding stage is maintained.

[0087] When the actual processing parameters are less than the preset actual judgment threshold and the load coefficient is greater than the preset load judgment threshold, the second condition is determined to be met. In this embodiment of the invention, the preset actual judgment threshold is 95%, and the preset load judgment threshold is 20%.

[0088] When the actual processing parameters and load coefficient meet the first condition, the valve opening is adjusted by the valve opening change ratio and the pulverizer's changing parameters. A smaller actual processing parameter and a higher load parameter on the pulverizing blade assembly indicate that the reason for the smaller actual processing parameter is an insufficient feed rate. This also shows that increasing the feed rate during the testing phase did not significantly change the previous phase, indicating that the current pulverizer can handle the feed rate of phospholipid raw material well. The blade spacing is appropriate and conforms to normal changes. Therefore, the current blade spacing is kept constant; the feed rate is further increased. If the change in feed rate has a smaller impact on the pulverizer's changing parameters, the feed rate can be increased more significantly based on the previous rate. The feed rate of phospholipid raw material is controlled by the valve opening of the feed hopper. Therefore, adjusting the feed rate of phospholipid raw material is equivalent to adjusting the valve opening of the feed hopper.

[0089] Calculate the ratio of valve opening degree in the current deployment stage to that in the previous deployment stage, and use it as the valve opening degree change ratio; The parameters of the pulverizer are subjected to negative correlation normalization mapping, and the result of the negative correlation normalization mapping is used as the initial adjustment coefficient.

[0090] In this embodiment of the invention, the negative correlation normalization mapping of the pulverizer's changing parameters can be achieved by using an exponential function with the natural constant as the base and the pulverizer's changing parameters as the exponent as the initial adjustment coefficient.

[0091] In another embodiment of the present invention, the pulverizer can be first normalized to sigmoid, and then the difference between the constant 1 and the normalized result value can be used as the initial adjustment coefficient.

[0092] The valve adjustment coefficient is obtained by combining the initial adjustment coefficient and the valve opening change ratio; wherein the initial adjustment coefficient and the valve opening change ratio are positively correlated with the valve adjustment coefficient.

[0093] Using the valve adjustment coefficient as a weight, the valve opening in the current deployment stage is weighted to obtain the valve opening in the next deployment stage, wherein the valve opening is limited to between 0-100%.

[0094] In some embodiments, the valve opening in the next dispensing phase The calculation formula is: ;in, This refers to the valve opening corresponding to the amount of material released during the current release phase. c represents the valve opening corresponding to the amount fed in the previous feeding stage; c represents the changing parameters of the crusher. This represents the valve opening change ratio; This is the initial adjustment factor; This is the valve adjustment coefficient. The symbol indicates a limit, restricting the valve opening to between 0% and 100%. It should be noted that since this invention analyzes data from a pulverizer undergoing pulverization, the valve opening corresponding to the feed amount in the previous feeding stage is not zero by default. If the valve opening in the previous feeding stage was zero, the intelligent control of the pulverizer will automatically stop, switching to manual control.

[0095] If the actual processing parameters do not meet the first and second conditions, then the actual processing parameters are greater than the preset actual judgment threshold.

[0096] When the actual processing parameters exceed the preset actual judgment threshold, the valve opening and blade spacing are adjusted based on the raw material retention coefficient. When the actual processing parameters are too large, it indicates that simply changing the feed rate can significantly alter the pulverizer's processing of phospholipid raw materials. The corresponding current blade spacing is reasonable and reflects changes in the pulverizer's processing during actual operation. Furthermore, the valve opening and blade spacing can be adjusted based on the pulverization capacity and the raw material retention coefficient.

[0097] When the actual processing parameter is greater than the preset actual judgment threshold, and the raw material retention coefficient is less than or equal to the preset accumulation threshold, it is determined that the third condition is met. In this embodiment of the invention, the preset accumulation threshold is 1. In other embodiments, the implementer may adjust this value according to the actual situation. That is, when the actual processing parameter is greater than 95%, and the raw material retention coefficient is less than or equal to 1.

[0098] When the actual processing parameters are large, but the packing coefficient is significantly small, it indicates that the current feeding stage has a good crushing effect and high processing efficiency. The amount of phospholipid raw material fed can be further increased appropriately, and the blade spacing can be reduced.

[0099] The opening adjustment coefficient is determined based on the crushing capacity and the raw material retention coefficient; wherein, the crushing capacity is positively correlated with the opening adjustment coefficient, and the raw material retention coefficient is negatively correlated with the opening adjustment coefficient. In this embodiment of the invention, the normalized value of the ratio of the crushing capacity to the raw material retention coefficient can be used as the opening adjustment coefficient.

[0100] When the raw material retention coefficient is less than or equal to the preset accumulation threshold, the valve opening in the current delivery stage is weighted by the positively correlated normalized mapping opening adjustment coefficient to obtain the valve opening in the next delivery stage.

[0101] In the embodiment of the present invention, the valve opening degree in the next dispensing stage The calculation formula is: ;in, This refers to the valve opening at the current deployment stage; For crushing and processing capacity; is the raw material retention coefficient; f is the normalization function, using the sigmoid normalization function; This is the opening adjustment coefficient.

[0102] Using the negative correlation normalized mapping opening adjustment coefficient as the weight, the blade spacing in the current deployment stage is weighted to obtain the blade spacing in the next deployment stage.

[0103] The spacing between the blade sets in the next deployment phase The calculation formula is: ;in, This represents the blade spacing during the current deployment phase.

[0104] When the actual processing parameters exceed the preset actual judgment threshold, and the raw material retention coefficient exceeds the preset accumulation threshold, the fourth condition is deemed met. When the raw material retention coefficient exceeds the preset accumulation threshold, the feed rate can be reduced, the valve opening adjusted, and the current blade spacing kept constant; only the valve opening is adjusted.

[0105] When the raw material retention coefficient is greater than the preset accumulation threshold, the valve opening in the current delivery stage is weighted by the negative correlation normalized mapping opening adjustment coefficient to obtain the valve opening in the next delivery stage.

[0106] Valve opening degree in the next deployment phase The calculation formula is: .

[0107] The valve opening for determining the blade spacing and feed rate under different conditions is used. Based on the valve opening and blade spacing, control commands are output to the crushing control mechanism to adjust the valve opening and blade spacing, thereby achieving intelligent control.
