Description

Technical Field

[0001] The present invention relates to a method for monitoring the wear degree and predicting the service life of a homogenizing valve and a high-pressure homogenizer, which is applicable to the technical field of high-pressure homogenization. Background Art

[0002] A high-pressure homogenizer is a processing device that shears and impacts materials under a high pressure of 100 - 2000 bar through a homogenizing valve assembly to achieve a nanoscale homogenization effect on the materials. In the early stage, high-pressure homogenizers were mainly applied in the food field for homogenizing and emulsifying samples such as fruit juices, milk, and food additives. However, with the continuous development of its technology, its application field has gradually expanded from the food field to the field of nanopharmaceutical preparation.

[0003] The working principle of a high-pressure homogenizer generally is to drive the material through a driving pump, so that the material is pumped from a feed channel with a larger size into a smaller homogenizing valve. Sufficient pressure is applied to the material through the pressure exerted by the driving pump and the sharply reduced space, and then combined with an impact ring in the homogenizing valve to achieve the crushing and homogenization of sample particles.

[0004] However, the valve core and valve seat of the homogenizing valve are subjected to high-pressure impacts and particle friction during long-term operation, and progressive wear will inevitably occur, resulting in a decrease in homogenization efficiency, an increase in energy consumption, and a decline in product quality. In traditional technologies, the wear degree of the homogenizing valve is mainly determined through manual empirical maintenance and regular disassembly and inspection. This method not only takes time and effort but also makes it difficult to accurately judge the wear degree of the homogenizing valve. Moreover, due to the lag in judging the wear degree of the homogenizing valve, sudden failures are extremely likely to occur during high-pressure homogenization production with high pressure requirements, which not only affects the efficiency of homogenization processing but also causes the material to be contaminated, resulting in unnecessary cost waste. Summary of the Invention

[0005] In order to solve the defects existing in the above-mentioned prior art, the present invention proposes a method for monitoring the wear degree and predicting the service life of a homogenizing valve and a high-pressure homogenizer.

[0006] On the one hand, the present invention provides a method for monitoring the wear degree and predicting the service life of a homogenizing valve. This method is based on a pneumatic homogenization structure, and the pneumatic homogenization structure includes: a homogenization chamber, a homogenizing valve disposed in the homogenization 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 of the cylinder and is connected to a piston inside the cylinder. The other side of the cylinder is communicated with an external high-pressure air source. The cylinder forms air pressure on the other side inside the cylinder through the external high-pressure air source to push the piston, and the piston pushes the push rod, so that the other end of the push rod can abut against the valve core of the homogenizing valve and apply pressure towards the valve seat to the valve core.

[0007] The method includes: S1 Calculate the structural conduction coefficient ; where A rod is the cross-sectional area of the push rod, and A valve is the cross-sectional area of the valve core; specifically, most of the valve cores of existing homogeneous valves are made of diamond, and most of the valve seats are made of cobalt-based alloys. Due to the structural strength and wear resistance of diamond materials, in actual applications, the valve core usually does not wear, and the wear of the homogeneous valve mostly occurs in the valve seat part. Therefore, calculating the structural conduction coefficient between the push rod and the homogeneous valve according to the cross-sectional area of the push rod and the cross-sectional area of the homogeneous valve core can avoid deviations between the structural conduction coefficient and the actual situation caused by valve seat wear, so as to ensure the accuracy of subsequent calculation results.

[0008] S2 Calculate the wear coefficient of the homogeneous valve in real time ; where P hom is the real-time homogeneous pressure in the homogeneous chamber, and P drive is the homogeneous air pressure applied by the cylinder to the push rod; specifically, the pneumatic homogeneous structure further includes a first pressure sensor arranged in the homogeneous chamber and a second pressure sensor arranged in the cylinder, so as to monitor the homogeneous pressure in the homogeneous chamber in real time through the first pressure sensor and the homogeneous air pressure output by the cylinder in real time through the second pressure sensor.

[0009] S3 Preset the wear thresholds C2 and C3 of the homogeneous valve, preset the pressure threshold P, and monitor the wear degree of the homogeneous valve in real time, where C2 > C3; by presetting the wear threshold of the homogeneous valve, the wear degree data of the homogeneous valve can be made digital and precise, which is convenient for operators to intuitively and quickly judge the wear degree of the homogeneous valve; When C2 ≥ η 磨损 > C3, it means that the homogeneous valve is in a severely worn state. Compare P hom with P. If P hom > P, the equipment stops running and an alarm is issued; in this state, the wear degree of the homogeneous valve is close to the critical value of damage. Therefore, it is necessary to judge whether the current homogeneous pressure exceeds the pressure threshold. If the current homogeneous pressure exceeds the pressure threshold, it means that the current wear degree of the homogeneous valve cannot support the homogeneous processing under the current high pressure, and there is a certain risk of failure, and it is necessary to stop the processing in time and replace the new homogeneous valve in advance; When η 磨损 ≤ C3, it means that the homogeneous valve is damaged, and the equipment stops running and an alarm is issued; to remind the operator to replace the homogeneous valve.

[0010] S4 Establish a dynamic model of homogeneous efficiency ; where a, b, and c are all constants, and t is the actual used duration of the current homogenization valve. Specifically, the dynamic model of homogenization efficiency is established based on the non-linear attenuation relationship between the wear degree of the homogenization valve and the homogenization time, and professional software such as Scipy.optimize, MATLAB, and Origin in Python is used. Among them, a represents the theoretical benchmark value of homogenization efficiency in the initial state of the homogenization valve (i.e., the state when t = 0), which is usually related to the cross-sectional area of the valve core of the homogenization valve. Generally, the larger the cross-sectional area of the valve core, the relatively smaller the value of a; b represents the sensitivity coefficient of the wear degree of the homogenization valve, that is, the rate at which the homogenization efficiency decreases with time increase, which is usually related to the model of the homogenization valve. If a wide-edge valve with higher wear resistance is selected for the homogenization valve, the value of b is relatively smaller, and vice versa; c is the time calibration parameter, mainly to ensure that the homogenization efficiency function is still meaningful when t is 0.

[0011] S5 Calculate the remaining life Δt of the homogenization valve; if η 磨损 ≤η 效率 / η0, then ; ; Δt = t1 - t0; where t0 is the theoretical used duration of the homogenization valve under the current wear degree, and t1 is the predicted used duration when the homogenization valve is damaged. When the wear coefficient is less than or equal to the ratio of the homogenization efficiency to the structure conduction coefficient, it indicates that the actual wear degree of the homogenization valve is higher than the theoretical wear degree. In this state, the homogenization efficiency is calibrated to the value under the current wear degree, that is, the homogenization efficiency is set equal to the product of the wear coefficient and the structure conduction coefficient. Then, the theoretical used duration of the homogenization valve under the current wear degree is calculated, and by setting the wear coefficient to the value when the homogenization valve is damaged, the total life of the current homogenization valve used until damage is calculated, and thus the remaining life of the current homogenization valve is obtained; 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 the homogenization efficiency to the structure conduction coefficient, it indicates that the actual wear degree of the homogenization valve is lower than the theoretical wear degree. However, due to the long-term high-pressure working environment of the homogenization valve, in addition to wear caused by processing samples, the homogenization valve itself also has stress fatigue. Before reaching the fatigue limit, the structure of the homogenization valve does not produce obvious deformation, which results in the wear coefficient not being able to accurately reflect the fatigue degree of the homogenization valve. In this case, if the remaining life of the homogenization valve is judged by its actual wear coefficient, it is very easy to have production failures caused by brittle fracture of the homogenization valve. Therefore, when η 磨损 >η 效率When it is η0, the homogenization efficiency is not calibrated. By setting the homogenization efficiency to the value when the homogenization valve is damaged, the total life of the homogenization valve until it is damaged is calculated. Then, based on the actual used duration of the current homogenization valve, the remaining life of the current homogenization valve is calculated.

[0012] Further, step S3 further includes: when C2≥η 磨损 >C3, and P hom ≤P, continuously monitor the wear degree of the homogenization valve and the real-time homogenization pressure P hom . This state indicates that the homogenization pressure of the current homogenization process is within the warning value range, and the current wear state of the homogenization valve can support the homogenization process at this pressure without interference.

[0013] Further, a preset wear threshold C1 of the homogenization valve is set, where C1>C2. When C1≥η 磨损 >C2, it indicates that the homogenization valve is in a slightly worn state, and continuously monitor the wear degree of the homogenization valve. This state usually does not affect the homogenization process and no interference is required; when η 磨损 >C1, it indicates that the homogenization valve is in a non-worn state, and continuously monitor the wear degree of the homogenization valve. This state means that the homogenization valve has just started to be used and no wear has occurred yet. In practical applications, this state can also be used to exclude faults such as defective homogenization valves or assembly deviations of the homogenization unit. For example, when the wear coefficient of a newly replaced homogenization valve is greater than C1, it means that the newly replaced homogenization valve is defective, or there are deviations in the processing and assembly of the wall surface of the homogenization chamber in the homogenizer. Specifically, the pneumatic homogenization structure further includes an operation screen, and the wear degree of the homogenization valve is visually fed back to the operator through the operation screen, which is convenient for the operator to perform replacement operations.

[0014] Further, 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 value ranges of a, b, and c, the accuracy of predicting the wear degree and life of the homogenization valve can be improved.

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

[0016] Due to the application of the above technical solutions, the present invention has the following advantages compared with the prior art: The method for monitoring the wear degree and predicting the service life of the homogenizing valve of the present invention, as well as the high-pressure homogenizer, can dynamically evaluate and track the wear degree of the homogenizing valve without stopping the machine or disassembling it for inspection by real-time monitoring and calculation of the homogenizing pressure and the homogenizing air pressure. This not only reduces the labor cost and improves the production efficiency, but also realizes the precise control of the wear degree of the homogenizing valve. Moreover, based on the wear degree of the homogenizing valve and the established dynamic model of the homogenizing efficiency, the remaining service life of the homogenizing valve can be predicted in real time, so that the production personnel can replace the homogenizing valve in time according to the actual production process, avoiding sudden failures during the processing, thereby improving the processing efficiency and product quality and avoiding unnecessary cost waste.

The same reference numerals in the drawings denote the same or similar components or parts. Those skilled in the art should understand that these drawings are not necessarily drawn to scale.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The technical solutions of the present invention will be described clearly and completely below with reference to the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] In addition, the technical features involved in 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] Refer to the attached Figure 1, on 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 the 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 of the cylinder 4 and is connected to the piston inside the cylinder 4. The other side of the cylinder 4 is communicated with an external high-pressure air source. The cylinder 4 uses the air pressure formed on the other side inside the cylinder 4 by the external high-pressure air source to push the piston, and then uses the piston to push 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 a pressure towards the valve seat to the valve core. During homogenization processing, the plunger is driven to reciprocate by the driving mechanism disclosed in the above-mentioned published patent, and the material in the measuring cup is sucked into the homogenizing mechanism in cooperation with a one-way valve. Then, the plunger drives the material to flow through the homogenizing valve. At the same time, the pressure regulating valve is opened, so that the high-pressure gas transported by the external high-pressure air source enters the cylinder, driving the push rod to push the valve core of the homogenizing valve. The pressure applied to the valve core by the push rod and the pressure applied to the material by the plunger jointly form a homogenization pressure in the homogenizing mechanism, thereby realizing the homogenization processing of the material.

[0021] The method includes: S1 Calculate the structural conduction coefficient ; where A rod is the cross-sectional area of the push rod 3, and A valve is the cross-sectional area of the valve core. Specifically, most of the valve cores of existing homogenizing valves are made of diamond material, and most of the valve seats are made of cobalt-based alloy material. Due to the structural strength and wear resistance of diamond materials, in actual applications, the valve core usually does not wear. The wear of the homogenizing valve mostly occurs in the valve seat part. Therefore, calculating the structural conduction coefficient between the push rod and the homogenizing valve according to the cross-sectional area of the push rod and the cross-sectional area of the homogenizing valve core can avoid deviations between the structural conduction coefficient and the actual situation caused by valve seat wear, so as to ensure the accuracy of subsequent calculation results.

[0022] S2 Calculate the wear coefficient of the homogenizing valve 2 in real time ; where P hom is the real-time homogenization pressure in the homogenizing chamber 1, and P [[ID=1⑨]] drive is the homogenization air pressure applied by the cylinder 4 to the push rod 3. Specifically, the pneumatic homogenizing structure also includes a first pressure sensor (shown by the reference numeral a in Figure 1 ) disposed in the homogenizing chamber and a second pressure sensor (shown by the reference numeral b in Figure 1 ) disposed in the cylinder, so as to monitor the homogenization pressure in the homogenizing 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.

[0023] S3 preset the wear thresholds C1, C2, and C3 of the homogenizing valve, and the pressure threshold P, and continuously monitor the wear degree of the homogenizing valve, where C1 > C2 > C3; by presetting the wear thresholds of the homogenizing valve, the wear degree data of the homogenizing valve can be made digital and precise, facilitating the operator to intuitively and quickly judge the wear degree of the homogenizing valve; When η 磨损 > C1, it indicates that the homogenizing valve is in a non-worn state, and continuously monitor the wear degree of the homogenizing valve; this state means that the homogenizing valve has just started to be used and no wear has occurred yet. In actual applications, this state can also be used to exclude faults such as defective homogenizing valves or assembly deviations of the homogenizing unit. For example, when the wear coefficient of a newly replaced homogenizing valve is greater than C1, it means that the newly replaced homogenizing valve is defective, or there are deviations in the machining and assembly of the wall surface of the homogenizing chamber in the homogenizer; When C1 ≥ η 磨损 > C2, it indicates that the homogenizing valve is in a slightly worn state, and continuously monitor the wear degree of the homogenizing valve. This state usually does not affect the homogenization process and no intervention is required; When C2 ≥ η 磨损 > C3, it indicates that the homogenizing valve is in a severely worn state. Compare P hom with P. If P hom > P, the equipment stops and an alarm is issued. In this state, the wear degree of the homogenizing valve is close to the critical value of damage. Therefore, it is necessary to judge whether the current homogenization pressure exceeds the pressure threshold. If the current homogenization pressure exceeds the pressure threshold, it means that the current wear degree of the homogenizing valve cannot support the homogenization process under the current high pressure, and there is a certain risk of failure, and it is necessary to stop the processing in time and replace the new homogenizing valve in advance; If P hom ≤ P, continuously monitor the wear degree of the homogenizing valve and the real-time homogenization pressure P hom , this state means that the homogenization pressure of the current homogenization process is within the warning value range, and the current wear state of the homogenizing valve can support the homogenization process under this pressure, and no intervention is required.

[0024] When η 磨损 ≤ C3, it indicates that the homogenizing valve is damaged, the equipment stops and an alarm is issued to remind the operator to replace the homogenizing valve.

[0025] S4 Establish a dynamic model of homogenization efficiency ; where a, b, and c are all constants, and t is the actual used duration of the current homogenization valve. Specifically, the dynamic model of homogenization efficiency is established based on the non-linear attenuation relationship between the wear degree of the homogenization valve and the homogenization time, and professional software such as Scipy.optimize, MATLAB, and Origin of Python is used. Among them, a represents the theoretical benchmark value of homogenization efficiency in the initial state of the homogenization valve (i.e., the state when t = 0), which is usually related to the cross-sectional area of the valve core of the homogenization valve. Generally, the larger the cross-sectional area of the valve core, the relatively smaller the value of a; b represents the sensitivity coefficient of the wear degree of the homogenization valve, that is, the rate at which the homogenization efficiency decreases with time, which is usually related to the model of the homogenization valve. If a wide-edge valve with higher wear resistance is selected for the homogenization valve, the value of b is 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. Preferably, 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 l5. By limiting the value ranges of a, b, and c, the accuracy of predicting the wear degree and life of the homogenization valve can be improved.

[0026] S5 Calculate the remaining life Δt of the homogenization valve; if η 磨损 ≤η 效率 / η0, then ; ; Δt = t1 - t0; Among them, t0 is the theoretical used duration of the homogenization valve under the current wear degree, and t1 is the predicted used duration when the homogenization valve is damaged. When the wear coefficient is less than or equal to the ratio of the homogenization efficiency to the structure conduction coefficient, it indicates that the actual wear degree of the homogenization valve is higher than the theoretical wear degree. In this state, the homogenization efficiency is calibrated to the value under the current wear degree, that is, the homogenization efficiency is equal to the product of the wear coefficient and the structure conduction coefficient. Then, the theoretical used duration of the homogenization valve under the current wear degree is calculated, and by making the wear coefficient take the value when the homogenization valve is damaged, the total life of the current homogenization valve used until damage is calculated, so as to calculate the remaining life of the current homogenization valve; If η 磨损 >η 效率 / η0, then; where d is a preset homogenization efficiency threshold; when the wear coefficient is greater than the ratio of the homogenization efficiency to the structural conduction coefficient, it indicates that the actual wear degree of the homogenization valve is lower than the theoretical wear degree. However, due to the long-term high-pressure working environment of the homogenization valve, in addition to wear caused by processing samples, the homogenization valve itself also has stress fatigue. Before reaching the fatigue limit, the structure of the homogenization valve does not produce obvious deformation, which leads to the wear coefficient not being able to accurately reflect the fatigue degree of the homogenization valve. In this case, if the remaining life of the homogenization valve is judged by its actual wear coefficient, production failures caused by brittle fracture of the homogenization valve are likely to occur. Therefore, when η 磨损 > η 效率 / η0, the homogenization efficiency is not calibrated. By setting the homogenization efficiency to the value when the homogenization valve is damaged, the total life of the homogenization valve used until damage is calculated, and then based on the actual used duration of the current homogenization valve, the remaining life of the current homogenization valve is calculated.

[0028] On the other hand, this embodiment also provides a high-pressure homogenizer that adopts the above-mentioned method for monitoring the wear degree and predicting the life of the homogenization valve.

[0029] Due to the application of the above technical solutions, the present invention has the following advantages compared with the prior art: The method for monitoring the wear degree and predicting the life of the homogenization valve of the present invention and the high-pressure homogenizer can dynamically evaluate and track the wear degree of the homogenization valve without stopping the machine or disassembling and inspecting by real-time monitoring and calculation of the homogenization pressure and homogenization air pressure. This not only reduces the labor cost and improves the production efficiency, but also realizes the precise control of the wear degree of the homogenization valve; and through the wear degree of the homogenization valve and the established dynamic model of the homogenization efficiency, the remaining life of the homogenization valve can be predicted in real time, so that production personnel can replace the homogenization valve in time according to the actual production process, avoiding sudden failures during the processing, thereby improving the processing efficiency and product quality and avoiding unnecessary cost waste.
