Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of physical experiment equipment, and particularly relates to an intelligent precise control wet particle elastic recovery coefficient measuring device. BACKGROUND

[0002] The elastic recovery coefficient, as one of the important parameters of particles, plays an important role in accurately analyzing the fluidization characteristics of a particle system. For a non-spherical wet particle system, the presence of liquid and the complexity of particle shape are the main reasons for the great difference between the fluidization behaviors of the non-spherical wet particle system and the dry particle system. In a dry particle system, particles rebound after collision, and the energy loss in the collision process can be described by the elastic recovery coefficient. The elastic recovery coefficient was first proposed by Newton and represents the energy dissipation in the collision process. In a non-spherical wet particle system, due to the presence of liquid and the irregular shape of particles, the non-spherical wet particles may agglomerate after collision, and the energy dissipation in the collision process of wet particles becomes complex. With the continuous research on the fluidization behavior of the wet particle system, researchers have proposed to use the wet particle elastic recovery coefficient to further accurately characterize the wet particle collision process.

[0003] In the process of measuring the wet particle elastic recovery coefficient, the measurement of the liquid film thickness and the capture of the particle rebound process will greatly affect the measurement results of the wet particle elastic recovery coefficient. The commonly used methods for measuring the liquid film thickness are the mass difference method and the optical method. The mass difference method is simple to operate, and the liquid film thickness can be directly obtained by measuring the mass difference of the collision plane after coating the liquid film. However, this method has a large measurement error. The optical method has high measurement accuracy, but it involves three sets of PIV optical measurement systems in the measurement process, and the operation process is very complex. Therefore, how to simply and accurately measure the liquid film thickness has become a key problem in the process of measuring the wet particle elastic recovery coefficient.

[0004] The commonly used methods for measuring the wet particle elastic recovery coefficient are the free fall method and the pendulum method. The free fall method has a simple experimental process, but due to the complex shape of non-spherical particles, it is difficult to predict the rebound trajectory of non-spherical wet particles in the process of measuring the elastic recovery coefficient of non-spherical wet particles by using the free fall method. Although the pendulum method can determine the collision position, it is difficult to form a stable liquid film in the vertical plane. At the same time, when the pendulum method is used to measure the wet particle elastic recovery coefficient, the rebound process of the non-spherical particle captured by the camera device only involves the two-dimensional motion of the particle in the xz plane, and the deflection motion of the particle in the xy plane (x, y, z plane diagram, as shown in Figure 1 SUMMARY

[0005] ​Therefore, the technical problem to be solved by the present application is to overcome the problem that in the prior art, when the pendulum method is used to measure the elastic recovery coefficient of wet particles, the rebound process of the non-spherical particles captured by the camera equipment only involves the two-dimensional motion of the particles in the xz plane, and the deflection motion of the particles in the xy plane is not considered, which greatly affects the measurement of the elastic recovery coefficient of wet particles, thereby providing an intelligent precision control wet particle elastic recovery coefficient measuring device.

[0033] The intelligent fine control wet particle elastic recovery coefficient measuring device can measure more accurate liquid film thickness in real time, and can shoot the motion trajectory of the rebound process of the particles on different planes, so as to more accurately measure the wet particle elastic recovery coefficient, thereby realizing more accurate measurement of the wet particle elastic recovery coefficient.

[0034] In actual use, the nano-magnetic fluid is coated on the particle collision device through the liquid control and redistribution device, the particles are fixed on the particle release device, the vacuum control device 3 is opened if the experiment is carried out under vacuum condition, the vacuum control device 3 is not opened if the experiment is carried out under normal temperature and pressure, then the data acquisition and control device is opened, the free fall of the particles is realized by operating the particle release device, finally the particle collision process obtained by the data acquisition device is analyzed by using the experimental result processing and analysis device 2, and the experimental result, that is, the different wet particle elastic recovery coefficient values, is obtained. The uniformity and stability of the liquid film need to be maintained in the wet particle experiment, and the first micro-spraying instrument and the second micro-spraying instrument are used to ensure the uniform distribution of the liquid film on the collision surface.

[0040] The first collision plane 15 and the second collision plane 18 are pre-coated with a layer of liquid film with a precisely controlled thickness, the liquid film redistribution is realized on the particles before release by using the first micro-spraying instrument and the second micro-spraying instrument, and the liquid evaporation is prevented by low-temperature condition. The real-time monitoring device is used to monitor the change of the liquid film in real time, which is helpful to study the influence of the liquid film thickness on the elastic recovery coefficient, and can realize consistent liquid film thickness in multiple experiments and reduce experimental errors.

[0041] The first vacuum release device 10, the first electromagnetic release device 11, the second electromagnetic release device 8 and the second vacuum release device 9 can ensure that particles of different types and sizes can be accurately released. When released, the vacuum release device and the electromagnetic release device are instantaneously cut off to release the particles at the microsecond level, so as to ensure that the particles are in a static state and have no initial speed.

[0042] The particle release device is sealed in the sealed box 1 and connected with the vacuum control device 3 to control the vacuum degree range. The measurement device can adjust the vacuum degree before release, or quickly adjust the air backflow after release, so as to study the motion characteristics of the particles under different air pressures.

At the same time, the system can also be automatically calibrated, and reset to the same initial state after each experiment, improving the efficiency of the experiment.

[0040] In this embodiment, the vacuum control device 3 is a vacuum pump. The vacuum control device 3 uses an adjustable vacuum environment to study the wet particle collision process under different resistance conditions by controlling the vacuum degree to reduce the influence of air resistance.

[0041] In some optional embodiments, the real-time monitoring device includes a first camera device 12 and a second camera device 4, the first camera device 12 and the second camera device 4 are arranged inside the sealed box 1, the first camera device 12 is arranged towards the first collision plane 15, the second camera device 4 is arranged towards the second collision plane 18, and the first camera device 12 and the second camera device 4 are connected with the experimental result processing and analysis device 2.

[0042] The first camera device 12 and the second camera device 4 are used to collect data of particles, and the collected data are transmitted to the experimental result processing and analysis device 2 for data analysis.

[0043] Meanwhile, the real-time monitoring device also includes a Doppler laser velocimeter 5, which is arranged in the sealed box 1 and connected with the computer.

[0044] A variety of non-contact monitoring methods can be used to ensure accurate tracking of particle movement. Doppler laser velocimeter 5 sensors and camera devices are arranged along the particle falling path in the sealed box 1.

[0045] The Doppler laser velocimeter 5 can monitor the speed change of the particles in real time, and the camera device is used to record the position and rotation of the particles and other small motion information. The combination of the Doppler laser velocimeter 5 sensor and the camera device enables the measuring device to capture all-around information such as the speed, position, and attitude of the particles. Especially in terms of the dynamic change of the liquid film of wet particles, the camera device can also cooperate with the filter to monitor the liquid film thickness in a special waveband.

[0046] In the embodiment, the first camera 12 and the second camera 4 are high-speed cameras.

[0047] The support frame 20 comprises a horizontal rod 21, a vertical rod 22, and a base 23. The horizontal rod 21 is arranged parallel to the base 23, and the vertical rod 22 is arranged between the horizontal rod 21 and the base 23. The support frame 20 can mount the first collision plane 15 and the second collision plane 18, the first vacuum release device 10, the first electromagnetic release device 11, the second electromagnetic release device 8, and the second vacuum release device 9 thereon, i.e., provides an installation carrier for the first collision plane 15 and the second collision plane 18, the first vacuum release device 10, the first electromagnetic release device 11, the second electromagnetic release device 8, and the second vacuum release device 9, and ensures the stability of the installation of the first collision plane 15 and the second collision plane 18, the first vacuum release device 10, the first electromagnetic release device 11, the second electromagnetic release device 8, and the second vacuum release device 9, thereby ensuring the accuracy of the measurement.

[0048] Specifically, the first vacuum release device 10 and the first electromagnetic release device 11 are arranged on the horizontal rod 21, and the second electromagnetic release device 8 and the second vacuum release device 9 are arranged on the vertical rod 22.

[0049] In the embodiment, the data acquisition and control device comprises a precision protractor 13 and a precision scale 16. The precision protractor 13 is arranged at the top of the support frame 20, and the precision scale 16 is arranged at the middle of the support frame 20.

[0050] The experimental result processing and analysis device 2 provides real-time data analysis and visualization functions to help researchers quickly understand the experimental results. The data acquisition and control device is connected to the computer software to process speed, position, and acceleration data in real time, and automatically calculate key parameters such as the elastic recovery coefficient of the particles according to the set model. The measurement device can generate real-time charts of experimental data, automatically compare multiple experimental results, provide intuitive data trend charts, and automatically label abnormal data points for easy troubleshooting.

[0051] When measuring the elastic recovery coefficient of non-spherical wet particles, i.e., using free fall measurement, the first electromagnetic release device 11 and the first vacuum release device 10, the first camera 12, the first confocal sensor 7, and the first collision plane 15 can be used for measurement.

[0052] When measuring the elastic recovery coefficient of spherical wet particles, i.e., using the pendulum method for measurement, the second electromagnetic release device 8 and the second vacuum release device 9, the second camera 4, the second confocal sensor 17, and the second collision plane 18 can be used for measurement.

[0053] The intelligent precision control wet particle elastic recovery coefficient measuring device adds the pendulum method and the free fall method into the same set of measuring devices, so that it can measure the elastic recovery coefficient of spherical wet particles and non-spherical wet particles. Meanwhile, the vacuum release device and the electromagnetic release device are used to expand the use range of the measuring device.

[0054] Real-time monitoring devices are added, two camera devices with different angles are used to capture the motion trajectory of the particles on different planes, and a Doppler laser speedometer 5 is added to monitor the real-time motion state of the particles. The liquid control and redistribution device is used to monitor the change of the liquid film thickness in real time, and the lost liquid is supplemented in time. Nano magnetic fluid is used as the liquid material, and different intensity magnetic fields are applied during the experiment to make the nano magnetic fluid lay on the vertical collision plane.

[0055] The specific working process of the intelligent precision control wet particle elastic recovery coefficient measuring device is as follows: the liquid film is coated on the collision plane by using the micro-spraying instrument, the liquid film thickness is measured by using the confocal sensor, and if there is a position with inconsistent liquid film thickness, the micro-spraying instrument is used for secondary spraying. After obtaining consistent liquid film thickness, the measured particles are fixed on the particle release device. If the particle shape is complex, the pendulum method is used for experimental research; if the particle shape is regular, the free fall method is used for experimental research.

[0056] The selection rules of the particle release device are as follows: if the particle density is large, the vacuum release device is difficult to adsorb the particles, and the electromagnetic release device is used. After releasing the particles, the Doppler laser speedometer 5 and the camera device are used to monitor the motion state of the particles in real time, and the wet particle elastic recovery coefficient is obtained by using the experimental data post-processing system after obtaining a complete experimental video.

[0057] After each experiment, the confocal sensor is used to measure the liquid film thickness after the particle collides with the liquid film. If the liquid film thickness changes or the liquid film thickness on the plate is not uniform, the micro-spraying instrument is used for liquid coating again. If the pendulum method is used for experiment, the magnetic field strength of the magnetic field generator 19 can be adjusted to keep the liquid film thickness stable and uniform.

[0058] The nano magnetic fluid is coated on the particle collision device by using the liquid control and redistribution device, the particles are fixed on the particle release system, the vacuum control device 3 is opened if the experiment is conducted in vacuum, and the vacuum control device 3 is not opened if the experiment is conducted at normal temperature and pressure. After that, the data acquisition and control device is opened, the free fall motion of the particles is realized by controlling the particle release device, and finally the particle collision process obtained by the data acquisition device is analyzed by using the experimental result processing and analysis device 2 to obtain the experimental result, that is, the different wet particle elastic recovery coefficient values.
