Description

Technical Field

[0001] This invention relates to a method for monitoring the wear degree and predicting the life of a homogenizing valve, as well as a high-pressure homogenizer, applicable to the field of high-pressure homogenization technology. Background Technology

[0002] A high-pressure homogenizer is a processing device that uses a homogenizing valve assembly to shear and impact materials under high pressure (100-2000 bar) to achieve nanoscale homogenization. Initially, high-pressure homogenizers were primarily used in the food industry for homogenizing and emulsifying samples such as fruit juice, milk, and food additives. However, with continuous technological advancements, their applications have gradually expanded from the food sector to the field of nanomedicine preparation.

[0003] The working principle of a high-pressure homogenizer is generally to drive the material through a drive pump, which pumps the material from a large feed channel into a small homogenizing valve. The pressure applied by the drive pump and the rapidly shrinking space apply sufficient pressure to the material. Combined with the impact ring in the homogenizing valve, the sample particles are crushed and homogenized.

[0004] However, the valve core and seat of a homogenizing valve are subjected to high-pressure impacts and particle friction during long-term operation, inevitably leading to progressive wear. This results in reduced homogenization efficiency, increased energy consumption, and decreased product quality. Traditionally, the wear level of the homogenizing valve is determined primarily through manual, experience-based maintenance and periodic disassembly inspections. This method is not only time-consuming and labor-intensive, but also difficult to accurately assess the wear level. Furthermore, due to the lag in assessing the wear level, sudden malfunctions are prone to occur during high-pressure homogenization processes, impacting processing efficiency and causing material contamination, resulting in unnecessary cost waste. Summary of the Invention

[0005] To address the shortcomings of the existing technology, this invention proposes a method for monitoring the wear degree of a homogenizing valve and predicting its lifespan, as well as a high-pressure homogenizer.

[0006] On one hand, the present invention provides a method for monitoring the wear degree and predicting the life of a homogenizing valve. The method is based on a pneumatic homogenizing structure, which includes: a homogenizing chamber, a homogenizing valve disposed in the homogenizing chamber, and a cylinder that applies pressure to the valve core of the homogenizing valve through a push rod. Specifically, one end of the push rod is slidably inserted into the cylinder from one side and connected to the piston inside the cylinder. The other side of the cylinder is connected to an external high-pressure air source. The cylinder pushes the piston through the air pressure formed on the other side of the cylinder by the external high-pressure air source, and pushes the push rod through the piston, so that the other end of the push rod can abut against the valve core of the homogenizing valve and apply pressure toward the valve seat to the valve core.

[0007] The methods include: S1 calculates the structural conductivity. Among them, A rod Let A be the cross-sectional area of ​​the push rod. valve This refers to the cross-sectional area of ​​the valve core. Specifically, the valve cores of most existing homogeneous valves are made of diamond, while the valve seats are mostly made of cobalt-based alloys. Due to the structural strength and wear resistance of diamond materials, the valve core usually does not experience wear in practical applications. The wear of homogeneous valves is mostly reflected in the valve seat. Therefore, calculating the structural transmission coefficient between the push rod and the homogeneous valve based on the cross-sectional area of ​​the push rod and the valve core can avoid deviations in the structural transmission coefficient from the actual situation due to valve seat wear, thus ensuring the accuracy of subsequent calculation results.

[0008] S2 calculates the wear coefficient of the homogenizing valve in real time. Among them, P hom P is the real-time homogenization pressure within the homogenization chamber. drive The cylinder applies homogenized air pressure to the push rod; specifically, the pneumatic homogenization structure also includes a first pressure sensor installed in the homogenization chamber and a second pressure sensor installed in the cylinder, so as to monitor the homogenization pressure in the homogenization chamber in real time through the first pressure sensor and monitor the homogenization air pressure output by the cylinder in real time through the second pressure sensor.

[0009] S3 presets the wear thresholds C2 and C3 of the homogenizer valve, presets the pressure threshold P, and monitors the wear degree of the homogenizer valve in real time, where C2 > C3; by preset the wear thresholds of the homogenizer valve, the wear degree of the homogenizer valve can be digitized and made more accurate, so that operators can intuitively and quickly judge the wear degree of the homogenizer valve. When C2≥η 磨损 If the value is greater than C3, it indicates that the homogenizer valve is in a state of severe wear. P should be adjusted accordingly. hom Compare with P, such as P hom If the pressure exceeds P, the equipment will stop and an alarm will be issued. In this state, the wear of the homogenizing valve is close to the critical value for damage. Therefore, it is necessary to determine whether the current homogenizing pressure exceeds the pressure threshold. If the current homogenizing pressure exceeds the pressure threshold, it means that the current wear of the homogenizing valve cannot support the homogenizing process under the current high pressure. There is a certain risk of failure. Processing needs to be stopped in time and a new homogenizing valve needs to be replaced in advance. When η 磨损 If the value is ≤C3, it indicates that the homogenizing valve is damaged, the equipment will stop and an alarm will be issued to remind the operator to replace the homogenizing valve.

[0010] S4 establishes a dynamic model of homogenization efficiency. Where a, b, and c are constants, and t is the actual usage time of the homogenizing valve. Specifically, the dynamic model of homogenization efficiency is established based on the nonlinear decay relationship between the wear degree of the homogenizing valve and the homogenization time, using professional software such as Python's Scipy.optimize, MATLAB, and Origin. Here, a represents the theoretical homogenization efficiency benchmark value of the homogenizing valve in the initial state (i.e., the state of t=0), which is usually related to the cross-sectional area of ​​the homogenizing valve core. Generally, the larger the cross-sectional area of ​​the valve core, the smaller the value of a. b represents the sensitivity coefficient of the wear degree of the homogenizing valve, that is, the rate at which the homogenization efficiency decreases with time. It is usually related to the model of the homogenizing valve. If a wide-side valve with higher wear resistance is selected for the homogenizing valve, the value of b will be relatively small, and vice versa. c is a time calibration parameter, mainly to ensure that the homogenization efficiency function is still meaningful when t is 0.

[0011] S5 calculates the remaining life Δt of the homogenizing valve; if η 磨损 ≤η 效率 / η0, then ; ; △t = t1 - t0; Where t0 is the theoretical service life of the homogenizing valve under the current wear level, and t1 is the estimated service life of the homogenizing valve when it is damaged. When the wear coefficient is less than or equal to the ratio of the homogenizing efficiency to the structural transmission coefficient, it means that the actual wear level of the homogenizing valve is higher than the theoretical wear level. In this state, the homogenizing efficiency is calibrated to the value under the current wear level, that is, the homogenizing efficiency is made equal to the product of the wear coefficient and the structural transmission coefficient. Then, the theoretical service life of the homogenizing valve under the current wear level is calculated. Then, by setting the wear coefficient to the value when the homogenizing valve is damaged, the total service life of the current homogenizing valve until damage is calculated, and the remaining service life of the current homogenizing valve is calculated. If η 磨损 >η 效率 / η0, then Where d is the preset homogenization efficiency threshold; when the wear coefficient is greater than the ratio of homogenization efficiency to structural conductivity, it indicates that the actual wear degree of the homogenizing valve is lower than the theoretical wear degree. However, since the homogenizing valve is in a high-pressure working environment for a long time, in addition to wear caused by processing samples, the homogenizing valve itself also experiences stress fatigue. Before reaching the fatigue limit, the structure of the homogenizing valve will not undergo significant deformation, which means that the wear coefficient cannot accurately reflect the fatigue degree of the homogenizing valve. In this case, if the remaining life of the homogenizing valve is judged by the actual wear coefficient, production failures caused by brittle fracture of the homogenizing valve are likely to occur. Therefore, when η 磨损 >η 效率When / η0, the homogenization efficiency is not calibrated. The homogenization efficiency is set to the value when the homogenization valve is damaged. The total lifespan of the homogenization valve from use to damage is calculated. Then, based on the actual usage time of the current homogenization valve, the remaining lifespan of the current homogenization valve is calculated.

[0012] Furthermore, step S3 also includes: when C2≥η 磨损 >C3, and P hom When P ≤ P, continuously monitor the wear degree of the homogenizing valve and the real-time homogenizing pressure P. hom This status indicates that the homogenization pressure of the current homogenization process is within the warning range, and the current wear condition of the homogenizing valve can support homogenization processing at this pressure without intervention.

[0013] Furthermore, a preset wear threshold C1 is set for the homogenizer valve, where C1 > C2. When C1 ≥ η 磨损 >C2 indicates that the homogenizing valve is in a state of slight wear. The wear level of the homogenizing valve should be continuously monitored. This state usually does not affect homogenization and requires no intervention; when η 磨损 When the wear coefficient is greater than C1, it indicates that the homogenizing valve is in a wear-free state. Continuous monitoring of the wear coefficient of the homogenizing valve is crucial. This state indicates that the homogenizing valve has just been used and has not yet shown signs of wear. In practical applications, this state can also be used to troubleshoot faults such as defective homogenizing valves or assembly deviations in the homogenizer. For example, if a newly replaced homogenizing valve has a wear coefficient greater than C1, it indicates that the newly replaced homogenizing valve is defective, or that there are deviations in the machining or assembly of the homogenizing chamber wall in the homogenizer. Specifically, the pneumatic homogenizing structure also includes an operation panel, which provides intuitive feedback on the wear coefficient of the homogenizing valve to the operator, facilitating replacement operations.

[0014] Furthermore, in step S4, a is any rational number between 500 and 700, b is any rational number between 50 and 120, and c is any rational number between 5 and 15. By limiting the range of values ​​for a, b, and c, the accuracy of predicting the wear degree and lifespan of the homogenizing valve can be improved.

[0015] On the other hand, the present invention also provides a high-pressure homogenizer that employs the above-mentioned method for monitoring the wear degree and predicting the life of the homogenizing valve.

[0016] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art: The method for monitoring the wear degree of homogenizing valves and predicting their lifespan, along with the high-pressure homogenizer of this invention, allows for the dynamic assessment and tracking of the wear degree of homogenizing valves without the need for shutdown or disassembly for inspection by real-time monitoring and calculation of homogenizing pressure and homogenizing gas pressure. This not only reduces labor costs and improves production efficiency but also enables precise control over the wear degree of homogenizing valves. Furthermore, by using the wear degree of homogenizing valves and the established dynamic model of homogenizing efficiency, the remaining lifespan of the homogenizing valves can be predicted in real time. This allows production personnel to replace the homogenizing valves promptly according to the actual production process, avoiding sudden failures during processing, thereby improving processing efficiency and product quality, and preventing unnecessary cost waste.

Homogenizing chamber; 2. Homogenizing valve; 3. Push rod; 4. Cylinder. Detailed Implementation

[0018] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0020] Reference Appendix Figure 1On the one hand, this embodiment provides a method for monitoring the wear degree and predicting the life of a homogenizing valve. This method is based on a pneumatic homogenizing structure, which includes: a homogenizing chamber 1, a homogenizing valve 2 disposed in the homogenizing chamber 1, and a cylinder 4 that applies pressure to the valve core of the homogenizing valve 2 through a push rod 3. Specifically, the pneumatic homogenizing structure in this embodiment adopts the homogenizing mechanism and pneumatic mechanism disclosed in the patent with publication number CN221412901U. In the pneumatic homogenizing structure, one end of the push rod 3 is slidably inserted into the cylinder 4 from one side and connected to the piston inside the cylinder 4. The other side of the cylinder 4 is connected to an external high-pressure air source. The cylinder 4 is filled with air through the external high-pressure air source. The air pressure generated on the other side pushes the piston, and the piston pushes the push rod 3, so that the other end of the push rod 3 can abut against the valve core of the homogenizing valve 2 and apply pressure towards the valve seat to the valve core. During homogenization, the plunger is driven to move back and forth by the drive mechanism disclosed in the above-mentioned patent, and the material in the cup is sucked into the homogenizing mechanism in conjunction with the one-way valve. Then, the material is driven to flow through the homogenizing valve by the plunger. At the same time, the pressure regulating valve is opened, so that the high-pressure gas delivered by the external high-pressure gas source enters the cylinder and drives the push rod to push the valve core of the homogenizing valve. The pressure applied by the push rod to the valve core and the pressure applied by the plunger to the material together form a homogenizing pressure in the homogenizing mechanism, thereby realizing the homogenization of the material.

[0021] The methods include: S1 calculates the structural conductivity. Among them, A rod Let A be the cross-sectional area of ​​push rod 3. valve This refers to the cross-sectional area of ​​the valve core. Specifically, the valve cores of most existing homogeneous valves are made of diamond, while the valve seats are mostly made of cobalt-based alloys. Due to the structural strength and wear resistance of diamond materials, the valve core usually does not experience wear in practical applications. The wear of homogeneous valves is mostly reflected in the valve seat. Therefore, calculating the structural transmission coefficient between the push rod and the homogeneous valve based on the cross-sectional area of ​​the push rod and the valve core can avoid deviations in the structural transmission coefficient from the actual situation due to valve seat wear, thus ensuring the accuracy of subsequent calculation results.

[0022] S2 calculates the wear coefficient of homogenizing valve 2 in real time. Among them, P hom P is the real-time homogenization pressure within homogenization chamber 1. drive The cylinder 4 applies homogenized air pressure to the push rod 3; specifically, the pneumatic homogenization structure also includes a first pressure sensor (attached) disposed within the homogenization chamber. Figure 1 (as shown in reference numeral a), the second pressure sensor installed inside the cylinder (attached) Figure 1 (as shown in reference numeral b), so that the homogenization pressure in the homogenization chamber can be monitored in real time by the first pressure sensor, and the homogenization pressure output by the cylinder can be monitored in real time by the second pressure sensor.

[0023] S3 presets the wear thresholds C1, C2, and C3 for the homogenizer valve, presets the pressure threshold P, and monitors the wear degree of the homogenizer valve in real time, where C1 > C2 > C3. By presetting the wear thresholds for the homogenizer valve, the wear degree of the homogenizer valve can be digitized and made more accurate, making it easier for operators to intuitively and quickly judge the wear degree of the homogenizer valve. When η 磨损 When the value is greater than C1, it indicates that the homogenizing valve is in a wear-free state, and the wear level of the homogenizing valve is continuously monitored. This state indicates that the homogenizing valve has just been used and has not yet shown wear. In practical applications, this state can also be used to troubleshoot faults such as defective homogenizing valves or assembly deviations in the homogenizer. For example, if the wear coefficient of a newly replaced homogenizing valve is greater than C1, it indicates that the newly replaced homogenizing valve is defective, or that there are deviations in the wall processing or assembly of the homogenizing chamber in the homogenizer. When C1≥η 磨损 When the value is >C2, it indicates that the homogenizing valve is in a state of slight wear. The wear level of the homogenizing valve should be continuously monitored. This state usually does not affect the homogenization process and no intervention is required. When C2≥η 磨损 If the value is greater than C3, it indicates that the homogenizer valve is in a state of severe wear. P should be adjusted accordingly. hom Compare with P, such as P hom If the pressure exceeds P, the equipment will stop and issue an alarm. In this state, the wear of the homogenizing valve is close to the critical value for damage. Therefore, it is necessary to determine whether the current homogenizing pressure exceeds the pressure threshold. If the current homogenizing pressure exceeds the pressure threshold, it means that the current wear of the homogenizing valve cannot support the homogenizing process under the current high pressure, and there is a certain risk of failure. Processing needs to be stopped in time and a new homogenizing valve needs to be replaced in advance. For example, P hom If the wear level is ≤P, then continuously monitor the wear level of the homogenizing valve and the real-time homogenizing pressure P. hom This status indicates that the homogenization pressure of the current homogenization process is within the warning range, and the current wear condition of the homogenizing valve can support homogenization under this pressure without intervention.

[0024] When η 磨损 If the value is ≤C3, it indicates that the homogenizing valve is damaged. The equipment will stop and issue an alarm to remind the operator to replace the homogenizing valve.

[0025] S4 establishes a dynamic model of homogenization efficiency. Where a, b, and c are constants, and t is the actual usage time of the homogenizing valve.

By limiting the range of values ​​for a, b, and c, the accuracy of predicting the wear degree and life of the homogenizing valve can be improved.

[0026] S5 calculates the remaining life Δt of the homogenizing valve; if η 磨损 ≤η 效率 / η0, then ; ; △t = t1 - t0; Where t0 is the theoretical service life of the homogenizing valve under the current wear level, and t1 is the estimated service life of the homogenizing valve when it is damaged.

If η 磨损 >η 效率 / η0, then; where d is the preset homogenization efficiency threshold; when the wear coefficient is greater than the ratio of homogenization efficiency to structural conduction coefficient, it indicates that the actual wear degree of the homogenizing valve is lower than the theoretical wear degree. However, since the homogenizing valve is in a high-pressure working environment for a long time, in addition to wear caused by processing samples, the homogenizing valve itself also suffers from stress fatigue. Before reaching the fatigue limit, the structure of the homogenizing valve will not produce obvious deformation, which means that the wear coefficient cannot accurately reflect the fatigue degree of the homogenizing valve. In this case, if the remaining life of the homogenizing valve is judged by the actual wear coefficient, production failures caused by brittle fracture of the homogenizing valve are likely to occur. Therefore, when η 磨损 >η 效率 When / η0, the homogenization efficiency is not calibrated. The homogenization efficiency is set to the value when the homogenization valve is damaged. The total lifespan of the homogenization valve from use to damage is calculated. Then, based on the actual usage time of the current homogenization valve, the remaining lifespan of the current homogenization valve is calculated.
