Description

Technical Field

[0001] The present invention relates to the technical field of high-pressure homogenizers, and in particular to a control method and a control system for high-pressure homogenizer equipment. Background Art

[0002] A high-pressure homogenizer, also known as a "high-pressure fluid nano-homogenizer," allows materials in a suspended liquid state to flow at high speed through a cavity with a special internal structure (a homogenizing head or a high-pressure homogenizing chamber) under ultra-high pressure, causing the material to undergo a series of changes in its physical, chemical, and structural properties, ultimately achieving a homogenized effect. It is primarily used for tissue dispersion in the biotechnology field, sample preparation in the pharmaceutical field, enzyme treatment in the food industry, detection of pesticide and veterinary drug residues in food, as well as in the pharmaceutical, cosmetic, paint, and petrochemical industries. The basic principle of a high-pressure homogenizer is to use an ultra-high-pressure jet beam as the driving force to transport the material mixed in the liquid to the homogenizing head. In the process of passing through the homogenizing head, strong shearing, impact, and airblast effects are generated, thereby breaking up the liquid substance or solid particles with the liquid as the carrier into ultra-fine particles.

However, these homogenization methods fail to consider fundamental parameters of different dimensions when controlling the operating state of high-pressure homogenization equipment. Furthermore, these methods fail to compensate for these multi-dimensional fundamental parameters to obtain more optimal homogenization decision control parameters, leaving room for further optimization of the homogenization performance.

[0004] Therefore, there is an urgent need to develop a high-pressure homogenization equipment control method and system that can obtain more optimal homogenization decision control parameters based on multi-dimensional basic parameters to improve the homogenization effect. Summary of the Invention

[0046] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with its embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and do not limit the scope of protection of the present invention.

The terms used herein in the specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0049] The "first" and "second" in the present invention do not represent specific quantities and orders, but are only used to distinguish names.

[0050] At present, the control of high-pressure homogenizers is generally done by determining the type and aperture of the homogenizing chamber and the homogenizing head, and then designing and adjusting the pressure of the high-pressure pump and the viscosity of the target liquid material (such as the ratio of solid particles to water) based on experience. During the actual use of the high-pressure homogenizer, if the pressure is too high, it is easy to damage the equipment, and if the pressure is too low, the homogenization effect cannot be achieved. Improper homogenization pressure setting, high feed viscosity, and excessive flow rate can easily cause blockage of the homogenization chamber. However, the existing high-pressure homogenizer control method does not integrate multi-dimensional parameters such as the type and aperture of the homogenization chamber, homogenization pressure, viscosity of the target liquid material, concentration, temperature and flow rate to automatically and intelligently obtain the optimal high-pressure homogenizer decision-making control parameters. The homogenization effect, production efficiency and degree of automation and intelligence need to be improved.

[0051] In order to solve the problems existing in the existing high-pressure homogenizer, this embodiment provides a control method for high-pressure homogenizer, such as Figure 1 As shown, it includes the following steps:

[0052] S1, for the target device, obtain multi-dimensional basic parameters and obtain the correction compensation value of each dimensional basic parameter.

[0053] The target device refers to the target high-pressure homogenization device. Different multi-dimensional basic parameters correspond to different target device types. For each dimensional basic parameter, an environmental impact parameter that may cause deviation or error in the basic parameter is obtained. A corresponding correction compensation function is constructed based on the environmental impact parameter. Alternatively, a mapping function is constructed based on the specific environmental impact parameter to the correction compensation value, and the corresponding correction compensation value is finally obtained.

[0054] Obtaining corrected compensation values for each fundamental parameter allows for the consideration of environmental factors that influence these multi-dimensional parameters, resulting in more accurate decision-making and control parameters for high-pressure homogenization equipment. This allows for accurate control of the equipment's operation based on these multi-dimensional parameters and corrected compensation values, improving homogenization effectiveness and production efficiency.

[0055] Preferably, in step S1, Figure 2 As shown, for the target device, the specific method for obtaining multi-dimensional basic parameters includes the following steps:

[0056] S11, for the target device, obtaining key parameters of the target device;

[0057] S12: Obtain multi-dimensional basic parameters according to the key parameters.

[0058] Specifically, the key parameters include but are not limited to the technical parameters of the homogenization chamber, the high-pressure pump and the technical parameters of the target liquid material, and the multi-dimensional basic parameters are extracted from the key parameters, including but not limited to the type and pore size of the homogenization chamber, the homogenization pressure, the viscosity, concentration, temperature and flow rate of the target liquid material.

[0059] S2, constructing a homogenization effect target optimization function according to the multi-dimensional basic parameters and the modified compensation value.

[0060] Specifically, a homogenization effect target optimization function can be constructed using multi-dimensional basic parameters and correction compensation values as independent variables and homogenization effect as dependent variable. As a preferred technical solution, the homogenization effect is obtained by comprehensive calculation based on the homogenization index, homogenization energy consumption, homogenization cavity damage index, and homogenization processing time after quantitative processing. In this way, the homogenization effect can more comprehensively reflect the final material homogenization quality and the overall homogenization performance of the high-pressure homogenization equipment, rather than being limited to judging the homogenization performance of the high-pressure homogenization equipment and the material homogenization quality through a single homogenization index indicator.

[0061] The homogenization chamber damage index can be obtained according to the homogenization processing time T, the viscosity Vis of the target liquid material, the concentration Den, the temperature Tem and the flow rate V. Specifically, the homogenization chamber damage index is Where e is a natural constant, η, λ1, λ2, and λ3 represent preset adjustment coefficients, which can be set and adjusted by technicians based on experience, and C represents a preset wear constant, which can be set by technicians based on the type and pore size of the homogenizing chamber. The preset wear constant C can be pre-set for homogenizing chambers of different types and pore sizes.

[0062] The homogeneity index is calculated from the initial particle size Ips of the material and the predicted particle size Pps after high-pressure homogenization. Specifically, the homogeneity index Homogeneous energy consumption EC=P×T, where P is the homogeneous power.

[0063] The homogenization effect is the weighted average of the homogenization index, homogenization energy consumption, homogenization cavity damage index and homogenization processing time after quantification.

[0064] S3, obtaining at least one set of preferred decision parameters according to the homogenization effect objective optimization function, and controlling the working state of the high-pressure homogenization equipment according to the at least one set of preferred decision parameters.

[0065] Preferably, if Figure 3 As shown, the specific method for controlling the working state of the high-pressure homogenizing device according to at least one set of the preferred decision parameters includes the following steps:

[0066] S31, randomly selecting a group of preferred decision parameters from at least one group of preferred decision parameters, or selecting an optimal group of preferred decision parameters from at least one group of preferred decision parameters.

[0067] S32: Based on the selected optimal decision parameters, control the working state of the high-pressure homogenization equipment.

[0068] Generally speaking, for the target high-pressure homogenization equipment, when the homogenization chamber type and aperture are certain, the decision parameters include but are not limited to the working power and output pressure of the high-pressure pump, the viscosity, concentration, temperature and flow rate of the target liquid material.

[0069] To sum up, the control method of the high-pressure homogenizing equipment obtains multi-dimensional basic parameters and corrected compensation values of the basic parameters of each dimension, and then constructs a homogenization effect target optimization function based on the multi-dimensional basic parameters and the corrected compensation values. Finally, based on the homogenization effect target optimization function, the optimal decision parameters are obtained to realize the control of the working state of the high-pressure homogenizing equipment. When controlling the working state of the high-pressure homogenizing equipment, it not only takes into account the basic parameters of different dimensions, but also corrects and compensates the multi-dimensional basic parameters, thereby improving the accuracy of the working state control of the high-pressure homogenizer, and can effectively improve the homogenization effect and production efficiency.

[0070] In addition, compared with the existing technology that uses a single homogeneity index indicator to judge the homogenization performance of high-pressure homogenization equipment and the homogenization quality of materials, the control method of the high-pressure homogenization equipment described in the present invention is based on the homogenization index, homogenization energy consumption, homogenization cavity damage index and homogenization processing time. After quantitative processing, the homogenization effect is comprehensively calculated, which can more comprehensively reflect the final material homogenization quality and the overall homogenization performance of the high-pressure homogenization equipment. It is not limited to judging the homogenization performance and material homogenization quality of high-pressure homogenization equipment through a single homogenization index indicator, and also provides a new idea for the analysis and judgment of the overall homogenization performance of high-pressure homogenization equipment.

[0071] As a preferred technical solution, Figure 4 As shown, the specific method for obtaining the correction compensation value of each dimensional basic parameter includes the following steps:

[0072] S13, obtaining multi-dimensional environmental parameters that may cause deviations in the basic parameters. The multi-dimensional environmental parameters include but are not limited to ambient temperature and humidity, vibration value, light intensity, noise value, and air pressure.

[0073] S14: constructing a parameter correction compensation factor model based on the multi-dimensional environmental parameters and the basic parameters. The parameter correction compensation factor model can be expressed as a function that obtains a parameter correction compensation factor for each dimensional basic parameter according to the corresponding multi-dimensional environmental parameter.

[0074] Specifically, for a certain dimensional basic parameter, the parameter correction compensation factor is obtained in combination with the basic parameter according to the size ratio between the multi-dimensional environmental parameter and the corresponding standard warning environmental parameter. For example, for a certain dimensional basic parameter A, its one dimensional environmental parameter is B1, and the corresponding warning environmental parameter is B2. When B1 is greater than or equal to B2, the parameter correction compensation factor fc corresponding to the dimensional environmental parameter is = (A / A1) * (B1 / B2); wherein A1 represents the preset basic value corresponding to the dimensional basic parameter, which can be set by technical personnel. The preset basic value can be understood as a standard parameter value, which can be set based on experience. At this time, the environmental parameter correction compensation factor corresponding to the dimensional basic parameter can be obtained by calculating the weighted average of the parameter correction compensation factors fc of multiple dimensions.

[0075] S15, obtaining the environmental parameter correction compensation factor of each dimensional basic parameter according to the parameter correction compensation factor model.

[0076] S16, obtaining a basic parameter characteristic value of each dimensional basic parameter, and obtaining a corrected compensation value of each dimensional basic parameter according to the basic parameter characteristic value and the environmental parameter correction compensation factor.

[0077] The correction compensation value of each dimensional basic parameter can be expressed as the product of the characteristic value of the dimensional basic parameter and the corresponding environmental parameter correction compensation factor.

[0078] By obtaining the corrected compensation value of each dimensional basic parameter, the environmental factors that affect the accuracy of the multi-dimensional basic parameters can be taken into account, so as to more accurately control the operation of the high-pressure homogenization equipment and improve the homogenization effect and production efficiency.

[0079] As a preferred technical solution, Figure 5 As shown, the specific method for obtaining at least one set of preferred decision parameters according to the homogenization effect objective optimization function includes the following steps:

[0080] S33, presetting a judgment index for iteratively optimizing the homogenization effect target optimization function.

[0081] The homogenization effect objective optimization function can be expressed as F(X)=F(Hc1, Hc2, HcP, Vis, Den, Tem, V). F(X) represents the homogenization effect under the decision parameter X. The homogenization effect objective optimization function F(X)=F(Hc1, Hc2, HcP, Vis, Den, Tem, V) represents the search for a set of optimal decision parameters so that the homogenization effect meets the preset requirements, that is, the homogenization effect corresponding to the ultimately obtained optimal decision parameters falls within the preset homogenization effect numerical range.

[0082] Furthermore, if the homogenization effect is the weighted average of the homogenization index, homogenization energy consumption, homogenization cavity damage index and homogenization processing time after quantization, then F(X)=F(Hc1, Hc2, HcP, Vis, Den, Tem, V) can be converted to

[0083] Where Hc1 and Hc2 represent the type and pore size of the homogenizing chamber, respectively. HcP represents the homogenizing pressure, i.e., the output pressure of the high-pressure pump. α1, α2, α3, and α4 are preset weight coefficients, set by technical personnel. α1, α3, and α4 are all negative numbers.

[0084] For the target high-pressure homogenization equipment, when the homogenization chamber type and aperture are constant, the decision parameters include but are not limited to the output pressure of the high-pressure pump, the viscosity, concentration, temperature and flow rate of the target liquid material.

[0085] The judgment indicators include but are not limited to the maximum number of iterations and the convergence threshold.

[0086] S34: Iteratively optimize the homogenization effect target optimization function based on the judgment index to obtain at least one set of preferred decision parameters.

[0087] Obtaining at least one set of optimal decision parameters through iterative optimization can provide a reference basis for the control of high-pressure homogenization equipment.

[0088] This embodiment also provides a control system for high-pressure homogenization equipment, including a parameter acquisition module, an optimization function construction module, and a control module.

[0089] The parameter acquisition module is used to obtain multi-dimensional basic parameters for the target equipment, and obtain the corrected compensation value of each dimensional basic parameter; the optimization function construction module is used to construct a homogenization effect target optimization function based on the multi-dimensional basic parameters and the corrected compensation value; the control module is used to obtain at least one set of preferred decision parameters based on the homogenization effect target optimization function, and control the working state of the high-pressure homogenization equipment based on at least one set of the preferred decision parameters.

[0090] Preferably, the parameter acquisition module includes a key parameter acquisition unit and a basic parameter acquisition unit.

[0091] The key parameter acquisition unit is used to acquire the key parameters of the target device for the target device; the basic parameter acquisition unit is used to acquire multi-dimensional basic parameters according to the key parameters.

[0092] Different target devices correspond to different multi-dimensional basic parameters. For each dimensional basic parameter, the environmental impact parameter that may cause deviation or error in the basic parameter is obtained. Based on this environmental impact parameter, a corresponding correction compensation function is constructed. Alternatively, based on the specific environmental impact parameter, a mapping function between the environmental impact parameter and the correction compensation value is constructed, and finally the corresponding correction compensation value is obtained.

[0093] Obtaining corrected compensation values for each fundamental parameter allows for the consideration of environmental factors that influence these multi-dimensional parameters, resulting in more accurate decision-making and control parameters for high-pressure homogenization equipment. This allows for accurate control of the equipment's operation based on these multi-dimensional parameters and corrected compensation values, improving homogenization effectiveness and production efficiency.

[0094] The parameter acquisition module also includes an environmental parameter acquisition unit, a compensation factor model construction unit and a modified compensation value acquisition unit.

[0095] The environmental parameter acquisition unit is used to acquire multidimensional environmental parameters that may cause deviations in the basic parameters; the compensation factor model construction unit is used to construct a parameter correction compensation factor model based on the multidimensional environmental parameters and the basic parameters, and obtain the environmental parameter correction compensation factor of each dimensional basic parameter based on the parameter correction compensation factor model; the correction compensation value acquisition unit is used to obtain the basic parameter characteristic value of each dimensional basic parameter, and obtain the correction compensation value of each dimensional basic parameter based on the basic parameter characteristic value and the environmental parameter correction compensation factor.

[0096] A homogenization effect target optimization function can be constructed using multi-dimensional basic parameters and correction compensation values as independent variables and homogenization effect as the dependent variable. As a preferred technical solution, the homogenization effect is calculated based on the homogenization index, homogenization energy consumption, homogenization cavity damage index, and homogenization processing time, after quantification. In this way, the homogenization effect can more comprehensively reflect the final material homogenization quality and the overall homogenization performance of the high-pressure homogenization equipment, rather than being limited to judging the homogenization performance of the high-pressure homogenization equipment and the material homogenization quality based on a single homogenization index indicator.

[0097] The homogenization chamber damage index can be obtained according to the homogenization processing time T, the viscosity Vis of the target liquid material, the concentration Den, the temperature Tem and the flow rate V. Specifically, the homogenization chamber damage index is Where e is a natural constant, η, λ1, λ2, and λ3 represent preset adjustment coefficients, which can be set and adjusted by technicians based on experience, and C represents a preset wear constant, which can be set by technicians based on the type and pore size of the homogenizing chamber. The preset wear constant C can be pre-set for homogenizing chambers of different types and pore sizes.

[0098] The homogeneity index is calculated from the initial particle size Ips of the material and the predicted particle size Pps after high-pressure homogenization. Specifically, the homogeneity index Homogeneous energy consumption EC=P×T, where P is the homogeneous power.

[0099] The homogenization effect is the weighted average of the homogenization index, homogenization energy consumption, homogenization cavity damage index and homogenization processing time after quantification, that is,

[0100] Preferably, the control module includes a judgment indicator preset unit and a decision parameter acquisition unit.

[0101] The judgment index preset unit is used to preset the judgment index for iteratively optimizing the homogeneous effect target optimization function; the decision parameter acquisition unit is used to iteratively optimize the homogeneous effect target optimization function based on the judgment index to obtain at least one set of preferred decision parameters.

[0102] The key parameters include the technical parameters of the homogenization chamber, the high-pressure pump and the technical parameters of the target liquid material, and the multi-dimensional basic parameters include the type and pore size of the homogenization chamber, the homogenization pressure, the viscosity, concentration, temperature and flow rate of the target liquid material.

[0103] Homogenization effect objective optimization function F(X)=F(Hc1, Hc2, HcP, Vis, Den, Tem, V). F(X) represents the homogenization effect under the decision parameter X. The homogenization effect objective optimization function F(X)=F(Hc1, Hc2, HcP, Vis, Den, Tem, V) represents finding a set of optimal decision parameters so that the homogenization effect meets the preset requirements. In other words, the homogenization effect corresponding to the ultimately obtained optimal decision parameters falls within the preset homogenization effect numerical range.

[0104] If the homogenization effect is the weighted average of the homogenization index, homogenization energy consumption, homogenization cavity damage index and homogenization processing time after quantization, then F(X)=F(Hc1, Hc2, HcP, Vis, Den, Tem, V) can be converted to Where Hc1 and Hc2 represent the type and pore size of the homogenizing chamber, respectively. HcP represents the homogenizing pressure, i.e., the output pressure of the high-pressure pump. α1, α2, α3, and α4 are preset weight coefficients, set by technical personnel. α1, α3, and α4 are all negative numbers.

[0105] For the control system of the high-pressure homogenizing equipment, it sets a parameter acquisition module, an optimization function construction module and a control module, obtains multi-dimensional basic parameters, and obtains the corrected compensation values of the basic parameters of each dimension, and then constructs a homogenization effect target optimization function based on the multi-dimensional basic parameters and the corrected compensation values. Finally, based on the homogenization effect target optimization function, the optimal decision parameters are obtained to realize the control of the working state of the high-pressure homogenizing equipment. When controlling the working state of the high-pressure homogenizing equipment, it not only takes into account the basic parameters of different dimensions, but also corrects and compensates the multi-dimensional basic parameters, thereby improving the accuracy of the working state control of the high-pressure homogenizer, and can effectively improve the homogenization effect and production efficiency.

[0106] In addition, compared with the existing technology that uses a single homogeneity index indicator to judge the homogenization performance of high-pressure homogenization equipment and the homogenization quality of materials, the control system of the high-pressure homogenization equipment described in the present invention is based on the homogenization index, homogenization energy consumption, homogenization cavity damage index and homogenization processing time, and comprehensively calculates the homogenization effect after quantitative processing. It can more comprehensively reflect the final material homogenization quality and the overall homogenization performance of the high-pressure homogenization equipment. It is not limited to judging the homogenization performance and material homogenization quality of high-pressure homogenization equipment through a single homogenization index indicator, and also provides a new idea for the analysis and judgment of the overall homogenization performance of high-pressure homogenization equipment.
