Description

Technical Field

[0001] This application relates to the field of intelligent cleaning technology, and in particular to a valve cleaning method and related equipment based on a composite ultrasonic field. Background Technology

[0002] During manufacturing and maintenance, valve components typically contain micro-filters, slits, and complex flow channels, making them highly susceptible to adsorbing micron-sized residues, oil, and oxide particles during processing or operation. These contaminants can cause sealing failures, flow control deviations, and reduced heat dissipation in high-precision valve components. Therefore, the cleaning process directly affects the reliability and service life of the valve cooling system. While widely used ultrasonic cleaning methods have strong decontamination capabilities, they suffer from uneven sound energy distribution, localized cleaning blind spots, and particle re-adhesion when dealing with multi-layered dense filters and deep channels, making it difficult to meet high cleanliness requirements.

[0003] In existing technologies, ultrasonic cleaning systems often employ specific power modes. When the structure of the valve is complex, it is difficult to achieve deep cleaning of the valve's interior or corners, resulting in poor cleaning performance.

[0004] In summary, the technical problems existing in the relevant technologies need to be improved. Summary of the Invention

[0005] The main objective of this application is to propose a valve cleaning method and related equipment based on a composite ultrasonic field, so as to achieve deep cleaning of special parts of the valve, improve the cleaning effect, and enhance the reliability and service life of the valve.

[0006] To achieve the above objectives, one aspect of this application proposes a valve cleaning method based on a composite ultrasonic field, the method comprising: After the valve is immersed in a cleaning tank containing cleaning fluid, a composite ultrasonic generator is activated. The composite ultrasonic generator generates a composite ultrasonic field composed of high-frequency and low-frequency ultrasound, which is used to perform ultrasonic cleaning on the valve. Based on the filter structure parameters of the cleaning tank, the power ratio of high-frequency ultrasound and low-frequency ultrasound is adjusted to form optimized ultrasound power. During ultrasonic cleaning using the composite ultrasonic field with optimized ultrasonic power, the concentration change of micron-sized residues in the cleaning fluid is monitored in real time to obtain residue concentration data. Based on the residue concentration data, the power ratio of the high-frequency ultrasound and the low-frequency ultrasound is dynamically adjusted until the residue concentration data is reduced to a preset threshold. Then, the composite ultrasound generator is stopped, and the cleaning of the valve is completed.

[0007] In some embodiments, adjusting the power ratio of high-frequency ultrasound to low-frequency ultrasound to form optimized ultrasonic power based on the filter structure parameters of the cleaning tank includes: Obtain the pore size and distribution density of the filter screen in the cleaning tank; Based on the aperture size and the distribution density, a preset ultrasonic response relationship table is consulted to determine the recommended reference value for the high-frequency and low-frequency ultrasonic power ratio. By combining the total available ultrasonic output power of the cleaning equipment, the power ratio reference value is proportionally corrected to obtain the actual high-frequency ultrasonic power and low-frequency ultrasonic power used. The high-frequency ultrasonic power and the low-frequency ultrasonic power are determined to be the optimized ultrasonic power, and the sum of the high-frequency ultrasonic power and the low-frequency ultrasonic power is less than the total available ultrasonic output power.

[0008] In some embodiments, the total available ultrasonic output power of the combined cleaning equipment is used to proportionally correct the power ratio reference value to obtain the actual high-frequency ultrasonic power and low-frequency ultrasonic power used, including... A first ratio value for high-frequency ultrasonic power is obtained, and a second ratio value for low-frequency ultrasonic power is obtained, wherein the sum of the first ratio value and the second ratio value is 1; Based on the first ratio value and the second ratio value, determine whether the high-frequency ultrasonic power and the low-frequency ultrasonic power exceed the maximum power limit; If the maximum power limit is exceeded, the first and second ratio values ​​are linearly compressed and adjusted, and then renormalized to obtain the corrected first and second ratio values. The actual high-frequency ultrasonic power and low-frequency ultrasonic power used are obtained by using the high-frequency ultrasonic power, the corrected first ratio value, the low-frequency ultrasonic power, and the corrected second ratio value.

[0009] In some embodiments, determining a recommended high-frequency to low-frequency ultrasonic power ratio reference value by querying a preset ultrasonic response relationship table based on the aperture size and the distribution density includes: Based on the aperture size and the distribution density, a two-dimensional interpolation method is used to find the closest ratio reference value range in a preset ultrasonic response relationship table; Based on the closest range of the aforementioned ratio reference values, the recommended high-frequency and low-frequency ultrasonic power ratio reference values ​​are determined.

[0010] In some embodiments, dynamically adjusting the power ratio of the high-frequency ultrasound and the low-frequency ultrasound based on the residue concentration data until the residue concentration data decreases to a preset threshold, and then stopping the composite ultrasound generator to complete the cleaning of the valve, includes: The concentration change rate is calculated based on the real-time residue concentration data. Based on the concentration change rate, determine whether the cleaning of the valve has entered a concentration decrease plateau period, the plateau period; If the plateau period is determined, the power of the high-frequency ultrasound is kept constant, and the power of the low-frequency ultrasound is gradually increased until the concentration change rate reaches a set range or the power of the low-frequency ultrasound reaches the upper limit.

[0011] In some embodiments, after the valve is immersed in a cleaning tank containing cleaning fluid and before the composite ultrasonic generator is activated, the method further includes: After the valve is fixed in a preset position in the cleaning tank, a preset volume of non-corrosive microemulsion cleaning solution is injected into the cleaning tank. When the level of the cleaning fluid exceeds a preset distance from the highest point of the valve, the injection of the cleaning fluid is stopped.

[0012] In some embodiments, during the ultrasonic cleaning process utilizing the composite ultrasonic field with optimized ultrasonic power, real-time monitoring of the concentration change of micron-sized residues in the cleaning fluid to obtain residue concentration data includes: During ultrasonic cleaning using the composite ultrasonic field with optimized ultrasonic power, a laser beam is emitted into the detection area in the cleaning fluid at a preset sampling period. Receives the light intensity signal fed back after being scattered by micron-sized residues in the cleaning solution; The light intensity signal is compared with a preset particle concentration calibration curve to calculate the current residue concentration data in real time. Obtain residue concentration data stored in time series.

[0013] To achieve the above objectives, another aspect of this application proposes a valve cleaning device based on a composite ultrasonic field, the device comprising: The start-up module is used to start the composite ultrasonic generator after the valve is immersed in the cleaning tank containing the cleaning fluid. The composite ultrasonic generator generates a composite ultrasonic field composed of high-frequency and low-frequency ultrasound, which is used to perform ultrasonic cleaning on the valve. The first adjustment module is used to adjust the power ratio of high-frequency ultrasound and low-frequency ultrasound according to the filter structure parameters of the cleaning tank to form optimized ultrasound power. The monitoring module is used to monitor the concentration change of micron-sized residues in the cleaning fluid in real time during the ultrasonic cleaning process using the composite ultrasonic field with the optimized ultrasonic power, and to obtain residue concentration data. The second adjustment module is used to dynamically adjust the power ratio of the high-frequency ultrasound and the low-frequency ultrasound based on the residue concentration data, until the residue concentration data is reduced to a preset threshold, at which point the composite ultrasound generator is stopped, and the cleaning of the valve is completed.

[0014] To achieve the above objectives, another aspect of this application provides an electronic device, which includes a memory and a processor. The memory stores a computer program, and the processor executes the computer program to implement the method described above.

This allows high-frequency sound waves to effectively remove surface microparticles, while low-frequency sound waves enhance penetration into the dense filter and its internal channels, thereby achieving highly efficient cleaning of various areas of valve-cooled precision components and significantly improving residue removal efficiency and cleaning uniformity.

[0024] Figure 1 This is an optional flowchart of the valve cleaning method based on a composite ultrasonic field provided in the embodiments of this application. Figure 1 The method may include, but is not limited to, steps S101 to S104.

[0025] Step S101: After the valve is immersed in the cleaning tank containing the cleaning fluid, the composite ultrasonic generator is started. The composite ultrasonic generator generates a composite ultrasonic field composed of high-frequency and low-frequency ultrasound, which is used to perform ultrasonic cleaning on the valve.

[0026] This step first requires establishing a stable cleaning environment. Specifically, this includes: Step S1011: Detect the valve component fixed in a preset position within the cleaning tank.

[0027] The precision valve components to be cleaned are fixed in a predetermined position inside the cleaning tank using a positioning fixture. The positioning fixture includes a vertical fixing structure for limiting movement and an elastic clamping device for holding the components, ensuring stability and positioning accuracy during the cleaning process. This avoids blind spots in cleaning caused by floating, tilting, or air bubble interference.

[0028] S1012: Inject a preset volume of non-corrosive microemulsion cleaning solution into the cleaning tank.

[0029] The automatic cleaning fluid injection device is activated, injecting a preset volume of cleaning fluid from the storage tank according to the set flow parameters. The cleaning fluid is a non-corrosive microemulsion system with a surface tension controlled at 20–30 mN / m and a viscosity controlled at 1.0–2.0 mPa·s to enhance its wetting and stripping ability against micron-sized particle residues. The injection process is precisely managed by a flow sensor and controller to ensure the accuracy of the injection volume.

[0030] S1013: When the liquid level of the cleaning fluid exceeds the preset distance from the highest point of the valve, the injection of the cleaning fluid will be stopped.

[0031] After the cleaning tank is filled with cleaning fluid, the liquid level stabilization module at the bottom of the tank is activated to maintain the cleaning fluid level at 5mm above the highest point of the valve, ensuring that the entire component is completely submerged in the cleaning environment, forming a uniform, closed, and bubble-free liquid phase cleaning environment. The liquid level stabilization module monitors the liquid level in real time through a float valve or electronic liquid level sensor and maintains a stable liquid level through feedback control.

[0032] After completing the preparation of the cleaning environment, start the compound ultrasonic generator. Specifically, this includes: S1014: Start the main control system of the composite ultrasound generator and load the initialization parameters for the high-frequency ultrasound component and the low-frequency ultrasound component respectively.

[0033] Initialization parameters include frequency setting, power output ratio, and duty cycle signal. The frequency setting for the high-frequency ultrasonic component is 40–80 kHz, and the frequency setting for the low-frequency ultrasonic component is 20–30 kHz. The main control system loads the initial frequency and power configuration based on the preset cleaning process parameters.

[0034] S1015: The synchronous drive module of the main control system sends modulation signals to the two sets of ultrasonic components to form time-domain phase difference control.

[0035] The modulation signal superimposes high-frequency and low-frequency ultrasound in the liquid medium to generate a composite sound field. The phase difference control angle range is 0° to 180° to achieve uniform distribution of sound wave energy. The synchronous drive module ensures that the high-frequency and low-frequency ultrasound components work in tandem in the time domain, avoiding energy loss caused by sound wave interference.

[0036] S1016: After the composite sound field is established, the main control system calls the power distribution module to distribute the total output power P according to the set ratio. λ 1 and λ 2 are respectively assigned to the high-frequency and low-frequency ultrasound components.

[0037] Power distribution satisfies the following formula:

[0038]

[0039] (1) in, This refers to the output power of the high-frequency ultrasound component. This refers to the output power of the low-frequency ultrasound component. This represents the total power of the composite ultrasonic generator. and This is the power allocation coefficient.

[0040] After power distribution and phase modulation, a composite ultrasonic field is formed within the cleaning tank, comprising high-frequency cavitation microflow and low-frequency penetrating vibration, providing the valve with dual-frequency synergistic vibration cleaning energy input. High-frequency sound waves are used to remove micron-sized residues from the surface, while low-frequency sound waves are used to penetrate the valve's dense filter screen and deep-hole channels.

[0041] Step S102: Adjust the power ratio of high-frequency ultrasound and low-frequency ultrasound according to the filter structure parameters of the cleaning tank to form optimized ultrasound power.

[0042] This step achieves efficient cleaning by dynamically adjusting the power ratio to match the ultrasonic energy with the valve's structural characteristics. Specifically, it includes: S1021: Obtain the filter screen structure parameters of the valve, including the filter screen pore size and distribution density.

[0043] The filter pore size d is expressed in micrometers (μm), and the distribution density n is expressed as the number of pores per unit area (pores / mm²). These parameters are obtained through optical measuring instruments or scanning electron microscopes and then input into the main control system.

[0044] S1022: Based on the aperture size and distribution density, consult the preset ultrasonic response relationship table to determine the recommended reference value for the high-frequency and low-frequency ultrasonic power ratio.

[0045] The ultrasonic response relationship table is a pre-defined two-dimensional lookup table built based on historical experimental data, linking filter parameters with the optimal ultrasonic power ratio. For example, Table 1 shows reference values ​​for the power ratio corresponding to some filter parameters: Table 1: Ultrasonic Response Relationship Table

[0046] The query process uses a two-dimensional interpolation method: the filter pore size d and distribution density n are substituted into the ultrasonic response relationship table to find the parameter range that is closest to the current filter characteristics, determine the corresponding recommended ultrasonic frequency intensity range, and extract the reference values ​​λ1 and λ2 for the high-frequency and low-frequency power ratio.

[0047] S1023: Based on the total available ultrasonic output power of the cleaning equipment, the power ratio reference value is proportionally corrected to obtain the actual high-frequency ultrasonic power and low-frequency ultrasonic power used.

[0048] The specific sub-steps include: S1023a: Obtain the total available ultrasonic output power of the current cleaning equipment. P (Unit: W), and read the power ratio reference values ​​λ1 and λ2, where λ1 + λ2 = 1.

[0049] S1023b: Determine whether the allocated power corresponding to reference values ​​λ1 and λ2 exceeds the maximum output limit of the device. P max .

[0050] If there is a risk of exceeding the limit (i.e.) If the reference value is linearly compressed according to the equipment's safe operating curve, a correction factor α is formed. The correction factor is defined as: (2) like If α=1, no adjustment is needed; if If α < 1, then linear compression is performed.

[0051] S1023c: Correct and normalize the reference values ​​for the proportions.

[0052] The revised ratio is:

[0053] (3) Renormalization ensures .

[0054] S1023d: Calculate the actual high-frequency ultrasonic power P1 and low-frequency ultrasonic power P2 used.

[0055]

[0056] (4) The resulting P1 and P2 are used as optimized ultrasonic power to drive high-frequency and low-frequency ultrasonic components.

[0057] S1024: Optimize the ultrasonic power input to the composite ultrasonic generator to form a power ratio that matches the structural characteristics of the valve filter.

[0058] The main control system adjusts the output of the high-frequency and low-frequency ultrasonic components according to the corrected power ratio to ensure that the acoustic energy is evenly distributed in the cleaning medium and achieve efficient cleaning.

[0059] Step S103: During the ultrasonic cleaning process using a composite ultrasonic field with optimized ultrasonic power, the concentration change of micron-sized residues in the cleaning fluid is monitored in real time to obtain residue concentration data.

[0060] This step provides data support for dynamically adjusting the power ratio by monitoring the residue concentration in real time. Specifically, it includes: S1031: Set a detection area in the cleaning tank and place a laser scattering particle concentration sensor in the detection area, and set the sampling interval to 5 seconds.

[0061] The sensor is mounted on the side wall or bottom of the cleaning tank to ensure that its laser beam can cover a representative area.

[0062] S1032: After the cleaning process is started, the sensor periodically emits a laser beam and receives the light intensity signal after being scattered by the micron-sized residue in the cleaning solution.

[0063] The laser beam wavelength is selected to be in the visible or near-infrared range to match the scattering characteristics of micron-sized residues.

[0064] S1033: The concentration of residue in the liquid is calculated in real time by comparing the intensity of scattered light with the preset particle concentration calibration curve.

[0065] The formula for calculating residue concentration is: (5) in, This represents the current residue concentration; The initial transmitted light intensity of the cleaning fluid; This represents the intensity of the currently collected scattered light. The preset calibration constant is obtained through standard particle concentration experiments.

[0066] The calibration curve was established through laboratory calibration, correlating the scattered light intensity with particle samples of known concentration.

[0067] S1034: Store the continuously collected residue concentration data in a time series.

[0068] Data is stored in the main control system's memory for subsequent trend analysis and dynamic adjustments.

[0069] Step S104: Based on the residue concentration data, dynamically adjust the power ratio of high-frequency ultrasound and low-frequency ultrasound until the residue concentration data decreases to a preset threshold, then stop the composite ultrasound generator to complete the cleaning of the valve.

[0070] This step analyzes concentration change trends and dynamically optimizes the power ratio to address efficiency variations during the cleaning process. Specifically, it includes: S1041: Receives time series data of residue concentration, calculates the concentration change rate, and determines whether the cleaning process has entered a plateau period of concentration decline.

[0071] The specific sub-steps include: S1041a: Continuously receive residue concentration data corresponding to each sampling period and construct a concentration change curve with time as the horizontal axis and concentration as the vertical axis.

[0072] S1041b: Calculate the concentration change rate at multiple consecutive sampling points before and after the current time t, and obtain the average change rate. ΔC t .

[0073] The formula for calculating the rate of change is: (6) in, The concentration at the current moment, Δt represents the concentration at the previous moment, and Δt represents the sampling interval.

[0074] S1041c: Will ΔC t Compare with the preset concentration change threshold ε.

[0075] like And this state lasts for more than the set duration. T s If the time is 30 seconds (e.g., 30 seconds), then the cleaning process is considered to have entered a plateau phase.

[0076] S1042: If a slowdown in the rate of concentration decrease is detected (entering a plateau phase), a power adjustment command is triggered to increase the proportion of low-frequency ultrasound power according to a preset adjustment rate.

[0077] The plateau phase indicates that surface residues have been largely removed, but deeper residues are difficult to remove. By increasing the proportion of low-frequency ultrasonic power, the penetration of sound waves is enhanced, promoting the desorption of deeper particles.

[0078] S1043: During the adjustment process, keep the high-frequency power constant and gradually increase the low-frequency power until the concentration change rate returns to the set range or reaches the maximum safe power limit.

[0079] The adjustment process is implemented through the power distribution module of the main control system, gradually increasing the value of λ2' while monitoring the concentration change rate. If the concentration change rate returns to the normal range (e.g., ...), the adjustment is initiated. ΔC t If the value is less than or equal to ε, then stop adjusting; if the maximum safe power limit is reached, then maintain the current ratio.

[0080] Step S105: When the concentration of micron-sized residues decreases to a preset threshold, stop the composite ultrasonic generator to complete the cleaning process.

[0081] This step automates the cleaning termination process by determining whether the residue concentration is consistently below a threshold. Specifically, it includes: S1051: During the cleaning process, continuously read the real-time output residue concentration data and compare the current detection value with the preset residue concentration threshold.

[0082] The threshold is set according to the cleanliness requirements of the valve, for example, 10 ppm (parts per million).

[0083] S1052: When the residue concentration is detected to be below the threshold C for three consecutive sampling periods. th If the change is less than the set deviation tolerance δ, it is determined that the concentration of residue in the cleaning solution has stabilized and reached the cleaning standard.

[0084] The deviation tolerance δ is used to avoid misjudgment; for example, δ = 0.1C. th .

[0085] S1053: Send a shutdown pre-command to the main control system of the composite ultrasound generator. The main control system sequentially performs graded power reduction operations for high-frequency and low-frequency ultrasound, causing the total output power to linearly decrease to zero within 5 seconds.

[0086] The graded power reduction operation avoids liquid disturbance or secondary particle adhesion caused by sudden stop of the sound field.

[0087] S1054: When the system detects that the output power has dropped to zero and the sound field vibration signal has completely disappeared, it automatically cuts off the ultrasonic power supply circuit and completes the cleaning process.

[0088] This application's embodiments construct a composite ultrasonic field with synergistic high-frequency and low-frequency effects, dynamically matching the power ratio to the filter structure characteristics. This allows high-frequency sound waves to effectively strip away surface microparticles, while low-frequency sound waves enhance penetration into the dense filter and its internal channels, thereby achieving highly efficient cleaning of various areas of the valve-cooled precision components and significantly improving residue removal efficiency and cleaning uniformity. Simultaneously, by introducing a real-time residue concentration monitoring and concentration platform identification mechanism, and combining it with a linear compression strategy to dynamically adjust the ultrasonic power output, adaptive control of the cleaning process is achieved while ensuring safe equipment operation. This further optimizes cleaning energy consumption and improves the controllability and stability of cleaning quality.

[0104] The valve cleaning method, apparatus, electronic device, storage medium, and program product based on a composite ultrasonic field provided in this application embodiment involve immersing the valve in a cleaning tank containing cleaning fluid, then activating a composite ultrasonic generator. The generator produces a composite ultrasonic field composed of superimposed high-frequency and low-frequency ultrasound waves for ultrasonic cleaning of the valve. The power ratio of the high-frequency and low-frequency ultrasound waves is adjusted according to the filter structure parameters of the cleaning tank to achieve optimized ultrasonic power. During ultrasonic cleaning using the composite ultrasonic field with optimized ultrasonic power, the concentration change of micron-sized residues in the cleaning fluid is monitored in real time to obtain residue concentration data. Based on the residue concentration data, the power ratio of the high-frequency and low-frequency ultrasound waves is dynamically adjusted until the residue concentration drops to a preset threshold, at which point the composite ultrasonic generator is stopped, completing the valve cleaning. This application constructs a composite ultrasonic field with synergistic high-frequency and low-frequency effects, dynamically matching the power ratio to the filter structure characteristics. This allows high-frequency sound waves to effectively remove surface microparticles, while low-frequency sound waves enhance penetration into the dense filter and channels, thereby achieving efficient cleaning of various areas of the valve's cold precision components and significantly improving residue removal efficiency and cleaning uniformity. Building upon this foundation, by introducing a real-time residue concentration monitoring mechanism and dynamically adjusting the ultrasonic power output, adaptive control of the cleaning process is achieved while ensuring safe equipment operation. This further optimizes cleaning energy consumption and improves the controllability and stability of cleaning quality.
