DETAILED DESCRIPTION

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Please refer to Figure 1 , Figure 1 A schematic structural diagram of an embodiment of the erosion device provided by the present invention.

[0028] In a specific embodiment, the erosion device includes:

[0029] A sample stage 36 for placing a sample 35 to be etched;

[0030] A heating system 2 is used to heat the abrasive particles 5 for performing an erosion operation on the sample 35 to a preset temperature;

[0031] a spraying system connected to the heating system 2 and configured to spray the heated abrasive particles 5 onto the surface of the sample 35 through the nozzle 30 of the spray gun 29;

[0032] A detection system for monitoring the sample status information of the sample 35 in real time, wherein the sample status information includes temperature, erosion rate, and flow rate;

[0033] The control system is connected to the injection system, the heating system 2 and the detection system, and is used to control the operating status of the injection system and the heating system 2 according to the status information of the sample 35 and the control instructions received.

[0034] A sample 35 to be eroded is placed on a sample stage 36. A heating system 2 is used to heat the abrasive particles 5 used for eroding the sample 35 to a preset temperature. The heated abrasive particles 5 are then sprayed onto the surface of the sample 35 through the nozzle 30 of the spray gun 29 by the spray system to perform the erosion operation. During this operation, a detection system monitors the status of the sample 35 in real time. The control system controls the operating status of the spray system and heating system 2 during operation. This device can simulate and precisely control the erosion speed, flow rate, height, and temperature of the abrasive particles 5, providing a more efficient and accurate experimental platform for testing the erosion properties of materials. It can simulate the erosion effects of abrasive particles 5 in a real working environment and ensure the reliability and accuracy of experimental data through precise control of parameters such as temperature, pressure, and flow rate.

[0035] It should be noted that the erosion device in this application can select different erosion particles for different tests, and is compatible with particles such as quartz sand, volcanic ash, borax, and quicklime, which are currently widely used in tests. There is no specific requirement for the size of the abrasive particles, but to ensure smooth feeding and heating to the required state within the specified time, the particle diameter must be less than or equal to 0.5 mm and the surface must be clean and free of impurities.

[0036] In this application, a detection system is used to monitor the erosion information of the sample 35 in real time. There is no limitation on the sensors used and the data adoption method. In one embodiment, the detection system includes an infrared sensor, an acoustic emission meter and a high-speed camera 32. The infrared sensor is used to monitor the surface temperature change of the sample 35, the acoustic emission meter 33 is used to detect the damage information of the sample 35, and the high-speed camera 32 is used to shoot and record the contact status information between the frosting particles 5 and the sample 35 during the erosion process.

[0037] By setting up an infrared sensor to monitor the surface temperature changes of the sample 35 in real time, the erosion temperature of the frosted particles 5 under different working conditions can be obtained. The damage information of the sample 35 can be detected by the acoustic emission instrument to clarify the erosion ability of the frosted particles 5. Finally, the contact status information between the frosted particles 5 and the sample 35 is recorded by the high-speed camera 32, so that the staff can obtain the erosion process of the frosted particles 5 on the sample 35 in the subsequent analysis process, providing data support for the subsequent improvement of material performance.

[0038] In order to further enhance the flexibility of the erosion process, in one embodiment, the erosion device further includes an erosion working chamber, a telescopic bracket 37 and a telescopic motor 38. The sample stage 36 is arranged in the erosion working chamber, and the sample stage 36 is installed at the driving end of the telescopic bracket 373. The telescopic motor 38 is connected to the telescopic bracket 37 and is used to adjust the position of the sample 35 relative to the nozzle 30 by controlling the telescopic state of the telescopic bracket 37.

[0039] An erosion chamber is provided, and a sample stage 36 is positioned within the chamber. The sample stage 36 is mounted on the drive end of a telescopic bracket 37. A telescopic motor 38 is connected to the bracket 37 and is used to adjust the position of the sample 35 relative to the nozzle 30 by controlling the telescopic state of the bracket 37. The erosion chamber facilitates the installation of the sample stage 36 and subsequent testing. The telescopic motor 38 and the bracket 37 facilitate adjustment of the position of the nozzle 30, allowing for different erosion intervals while also adjusting the angle, thereby improving testing efficiency.

[0040] The present application includes but is not limited to the above-mentioned structures of the erosion studio, telescopic bracket 37 and telescopic motor 38, and other structures may also be used.

[0041] In order to further facilitate the fixation of the spray gun 29, improve the stability of the test, and also facilitate the adjustment of the injection parameters of the frosting particles 5, in one embodiment, the erosion device also includes a spray gun bracket 28 arranged in the erosion working chamber for fixing the spray gun 29, and the spray gun 29 is provided with an erosion temperature sensor 25, an erosion flow sensor 26 and an erosion pressure sensor 27 for detecting the temperature, flow rate and pressure of the frosting particles 5 during the spraying process of the spray gun 29.

[0042] By setting up the spray gun bracket 28 to fix the spray gun 29, it can be ensured that during the process of spraying the frosting particles 5, no matter how the parameters such as the spray air flow pressure change, the recoil force generated by the backlash will not change the position of the spray gun 29, thereby improving the reliability of the spraying.

[0043] In addition, an erosion temperature sensor 25, an erosion flow sensor 26 and an erosion pressure sensor 27 are provided on the spray gun 29 to detect the temperature, flow rate and pressure of the frosting particles 5 during the spraying process of the spray gun 29. The status information of the output frosting particles 5 can be obtained in real time. By comparing with the status information of the sample 35, the erosion capacity under different working conditions can be obtained, thereby improving the accuracy and reliability of the test.

[0044] The present application does not limit the types and installation methods of the erosion temperature sensor 25 , the erosion flow sensor 26 and the erosion pressure sensor 27 .

[0045] Since during the actual erosion process, the abrasive particles 5 may rush out of the erosion area, causing pollution to the surrounding environment and even damage to external equipment and personnel, in one embodiment, the erosion device also includes a protective cover 34 arranged in the erosion studio, which is used to isolate the erosion area where the telescopic bracket 37, the telescopic motor 38, and the sample stage 36 are located from the non-erosion area.

[0046] By setting a protective cover 34 in the erosion studio, the erosion area where the telescopic bracket 37, the telescopic motor 38 and the sample stage 36 are located is isolated from the non-erosion area, and the ejected abrasive particles 5 are limited to the working range of the erosion studio, ensuring reliability and safety of use.

[0047] The control system in the present application is used to control the various components of the device. In order to further improve management efficiency, in one embodiment, the erosion device also includes a control cabinet 1 for installing the control system. The control cabinet 1 is provided with a human-machine interface adjustment display panel for displaying the detection data of the sensor obtained by the control system, and for sending control instructions to the control system, and for sending the equipment safe operation parameter range to the control system.

[0048] By installing the control system into the control cabinet 1, each control device can be isolated and protected, and the maintenance efficiency and management efficiency can be improved. By adjusting the display panel through the human-machine interface, the display, input and sending of parameters can be realized, thereby improving the convenience of management.

[0049] In addition, remote data input and output can be achieved by adding a communication module.

[0050] The heating system 2 in the present application is used to heat the frosting particles 5. There is no limitation on the heating process and the heating components. In one embodiment, the heating system 2 includes a heating power supply, a heating element, a temperature sensor 25 and a temperature control unit. The heating power supply is connected to the heating element to provide electrical energy to the heating element. The heating element includes a plurality of heating components for heating the frosting particles 5 through the heating components. The temperature sensor 25 is used to measure the temperature of the frosting particles 5. The temperature control unit is connected to the heating element and the temperature sensor 25 to control the heating power of the heating element according to the real-time temperature value obtained by the temperature sensor 25.

[0051] The heating element is powered by a heating power supply, which can be directly heated by a resistance wire, or heated by a crucible, or heated by gas combustion, or heated by other methods. During the heating process, a temperature sensor 25 is used to detect the temperature, so that the heating process can be monitored in real time and efficiently controlled by a temperature control unit.

[0052] The present application does not limit the types and control methods of the thermal power source, heating element, temperature sensor 25 and temperature control unit.

[0053] In addition, in this application, considering the heating efficiency and the sensitivity and controllability of the heating temperature, a resistance furnace is preferably selected as the heating element, which can heat the particles to the desired temperature and state in a short time.

[0054] In this application, the abrasive particles 5 need to be sprayed out through a spray gun 29 to perform related erosion operations. In order to improve the stability of the operation, in one embodiment, the erosion device also includes an airflow system connected to the injection system, and the airflow system includes an air compressor 18, a gas storage tank, and a gas flow control unit. The air compressor 18 is used to generate high-pressure airflow, the gas storage tank is used to store the high-pressure airflow, and the gas flow control unit is used to control the erosion speed and erosion distance of the abrasive particles 5 by adjusting the pressure of the gas output by the gas storage tank.

[0055] The airflow system allows for a stable output of abrasive particles 5, improving the stability and reliability of subsequent tests and enhancing the authenticity of the data. The air compressor 18 generates high-pressure airflow and stores it in a gas storage tank, ensuring the controllability and stability of the output airflow during use. The gas flow control unit controls the output flow rate, achieving efficient control of the output airflow.

[0056] It should be pointed out that, in the present application, the output of gases of different pressures can be achieved by setting up multiple gas storage tanks of different pressures, or setting up buffer tanks. In the present application, there is no limitation on the structure of the air compressor 18, the gas storage tank, and the gas flow control unit. In addition, a temperature controller can be added to achieve the output of airflow of gases of different temperatures, so as to reduce the impact on the temperature of the frosting particles 5 during the airflow purge. For example, if the purge airflow is at a low temperature and the frosting particles 5 are at a high temperature after heating, during the purge process, different airflows will have different cooling effects on the frosting particles 5. On the contrary, using a heated purge airflow for purge can avoid lowering the temperature of the frosting particles 5 and improve the reliability of the operation.

[0057] Since the need for heating may cause damage to the equipment during actual operation, in order to improve the reliability of use, in one embodiment, the erosion device also includes a cooling system 16 connected to the injection system and the sample stage 36, and the cooling system 16 includes a cooling water tank, a cooling pipe and a water pump. The cooling system 16 is used to pump the coolant in the cooling water tank to the cooling pipe through the water pump to cool the injection system and the sample stage 36.

[0058] By providing the cooling system 16 , the injection system and the sample stage 36 are cooled to avoid damage thereof due to continuous high temperature, thereby improving the reliability of use.

[0059] The structure of the cooling system 16 in this application includes but is not limited to a cooling water tank, cooling pipes and a water pump.

[0060] In this application, the output of the frosting particles 5 is performed through an injection system, but this may be unsustainable. In order to solve this technical problem, in one embodiment, the erosion device also includes a particle conveying system connected to the injection system, and the particle conveying system includes a hopper, a tray, a sand feeding screw, a sand dropout chute 6, a funnel 7, a sand separator 8, and a turntable 9, which are used to uniformly convey and disperse the frosting particles 5 to the heating system 2, wherein the frosting particles 5 are discharged from the hopper, lifted to the sand dropout chute 6 by the sand feeding screw, and enter the sand separator 8 through the funnel 7. The sand separator 8 is arranged on the turntable 9, and the turntable 9 is driven to rotate by the motor 14, so that the sand separator 8 evenly scatters the frosting particles 5 to the heating system 2.

[0061] After the frosted particles 5 are discharged through the hopper, they are lifted to the sand dropout chute 6 by the sand feeding spiral and enter the sand separator 8 through the funnel 7. The sand separator 8 is arranged on the turntable 9. The turntable 9 is driven to rotate by the motor 14, so that the sand separator 8 evenly scatters the frosted particles 5 to the heating system 2, which can ensure that the frosted particles 5 are evenly heated, and the temperature of the frosted particles 5 at various locations is kept consistent. In addition, the frosted particles 5 can be continuously provided to the heating system 2, thereby ensuring the continuity of the test and improving the test effect.

[0062] The present application includes but is not limited to the particle delivery system described above.

[0063] During the erosion process of the device of the present application, the content of frosted particles per unit time is controlled by the flow controller of the sand outlet 17. The amount of sand output is mainly controlled by the rotation of the spiral structure, thereby controlling the content of frosted particles per unit time. At the same time, this also realizes the control of the content of frosted particles under the condition of constant air pressure.

[0064] During erosion, the central control system can calculate the initial heating power based on the input parameters such as heating material, heating temperature, and room temperature, and then feed back the temperature to the control system in real time based on the temperature sensor at the spray gun. The control system then fine-tunes the heating power until the temperature reaches the set temperature. Therefore, this system is a heating and purging system.

[0065] Before erosion, a trial erosion will be carried out first. The temperature sensor at the spray gun will perform real-time temperature testing and feedback to the heating system, which will then adjust the heating power until the eroded temperature reaches the set temperature.

[0066] Therefore, although the compressed air will affect the temperature of the abrasive particles during the purge process, the system will perform feedback adjustment to compensate for the heat loss during the purge process. It should be noted that the power of the entire heating system is changing dynamically.

[0067] In one embodiment, the erosion device includes a main structure, a control system, a heating system 2 , an air flow system, a particle conveying system, an injection system, a detection system and a cooling system 16 .

[0068] The main structure includes an erosion studio, a frame, a sample table 36, a telescopic bracket 37, a telescopic motor 38 and a protective cover 34. The studio has space to accommodate a sample 35 and related devices; the sample table 36 can be moved in a vertical direction through the telescopic bracket 37 and the telescopic motor 38 to adjust the position of the sample 35 relative to the nozzle 30. The protective cover 34 is used to isolate the erosion area to protect the surrounding environment and personnel safety.

[0069] The control system is set in the control cabinet 1 and is used to collect signals from various sensors (such as temperature sensor 25, flow sensor 26, pressure sensor, etc.) in real time, adjust and control test parameters such as erosion pressure, injection speed and temperature of abrasive particles 5 through the human-machine interface to ensure the accuracy and stability of the test process, and finally output the result data of the erosion test.

[0070] Heating system 2 is used to heat sample 35 to the desired high temperature. This system includes a heating power supply, a heating element, and a temperature sensor 25. The heating element heats the abrasive particles 5 via a heating assembly, while the temperature sensor 25 measures the temperature changes of the abrasive particles 5. Heating system 2 is connected to a temperature control unit to ensure precise temperature control.

[0071] The airflow system consists of an air compressor 18, a gas storage tank, and a gas flow control device. Its primary function is to generate high-pressure airflow, driving abrasive particles 5 through nozzle 30 and spraying them onto the surface of sample 35. The airflow system is connected to a pressure control unit, which adjusts the gas pressure in real time to control the erosion speed and distance of the abrasive particles 5. Gas pressure is fed back to the control system via a pressure sensor to ensure airflow stability and accuracy.

[0072] The particle conveying system includes a hopper, its tray, a sand-feeding auger, a sand-falling chute 6, a funnel 7, a sand separator 8, and a turntable 9. It is used to evenly convey and disperse the frosted particles 5 to a heating device 12. Specifically, the frosted particles 5 are discharged from the hopper, lifted by the auger to the sand-falling chute 6, and then enter the sand separator 8 through the funnel 7. The turntable 9 is driven by a motor 14 to rotate, causing the sand separator 8 to evenly distribute the frosted particles 5 onto the heating device 12. The hopper is fixed by a bracket 3. The particle conveying system is sealed by a box cover 10. A sampling station can also be installed horizontally at the output end of the hopper to sample the output frosted particles 5 to form a test sample 11.

[0073] The spray system is used to spray abrasive particles 5 onto the surface of sample 35 using a high-pressure airflow. The spray system includes a pipeline for abrasive particles 5, a spray gun 29, and a nozzle 30. The design of nozzle 30 ensures that abrasive particles 5 can be sprayed evenly and stably onto the surface of sample 35, achieving the effect of simulating actual erosion.

[0074] The detection system is used to monitor the status of sample 35 in real time, including temperature, erosion rate, and flow rate. This system includes an infrared sensor, an acoustic emission device, and a high-speed camera 32. The infrared sensor monitors surface temperature changes of sample 35, the acoustic emission device detects damage to sample 35, and the high-speed camera 32 captures the erosion process, recording the moment particles come into contact with sample 35 and providing a basis for data analysis.

[0075] Because high-temperature operation can cause the equipment to overheat, a cooling system 16 is designed to cool the equipment. This system circulates coolant water to maintain temperatures within a safe range across the equipment. This system includes a cooling water tank, cooling pipes, and a pump to ensure that the equipment is protected from overheating during high-temperature experiments.

[0076] The frosted particles 5 are installed in the tray of the sand feeder 4, and are sent to the sand dropout chute 6 through the sand feeding spiral, enter the funnel 7, and fall onto the sand separator 8. The turntable 9 is driven by the motor 14 to rotate, so that the sand separator 8 scatters the frosted particles 5 on the surface of the heating device 12 for heating. The heating system 2 controls the heating device 12 to complete the heating task of the frosted particles 5. The heated frosted particles 5 fall to the sand outlet 17 through the sand sliding plate 15. At this time, the air compressor generates high-pressure air and fills it into the gas cylinder 22 through the gas input pipe 21. The gas cylinder pressure sensor 20 monitors the gas cylinder pressure in real time to ensure safety. The high-pressure gas in the gas cylinder 22 is transported to the sand outlet 17 through the erosion pressure pipe 19, and the frosted particles 5 are pressurized and sent to the high-pressure frosted particles. Pipeline 24 finally reaches spray gun 29, which is secured by a spray gun bracket 28. Gun 29 is equipped with an erosion temperature sensor 25, an erosion flow sensor 26, and an erosion pressure sensor 27 to detect the temperature, velocity, and pressure of the abrasive particles 5 eroding. The particles are then sprayed onto the surface of sample 35 through nozzle 30. A protective cover 34 is installed within the erosion chamber for protection. An infrared damage detector 31, a high-speed camera 32, and an acoustic emission device 33 are also installed to monitor the erosion process and effects in real time. Sample 35 is mounted on a sample stand 36, beneath which is a telescopic bracket 37. This bracket, controlled by a telescopic motor 38, enables vertical movement of the eroded sample 11. The entire system is controlled by a control system within control cabinet 1. This control system collects signals from each sensor in real time and controls the erosion pressure, velocity, and temperature of the abrasive particles 5 by controlling the air compressor and heating system 2. The erosion test results are then output through the control system's interactive interface.

[0077] The erosion device utilizes a modular design, with all components precisely arranged and connected to ensure stable operation under extreme conditions such as high temperature and high pressure. The implementation plan will describe in detail the specific structure and function of each component, as well as the interconnections between them. It is divided into several main areas: control system area, airflow system area, feed system area, heating system area 2, injection system area, detection system area, and cooling system area 16. Each area is rationally connected and arranged to ensure efficient system operation.

[0078] Conveying and Heating Frosted Particles 5: Frosted particles 5 are placed in the tray of sand feeder 4. Driven by a sand feed screw, they enter a sand dropout chute 6 and fall through a funnel 7 onto a sand separator 8. Subsequently, a turntable 9, driven by a motor 14, rotates, causing the sand separator 8 to evenly distribute the frosted particles 5 onto the surface of a heating device 12. The heating system 2 controls the heating device 12 to heat the dispersed frosted particles 5 until their temperature reaches the set value.

[0079] Pressurized Sand Delivery: The heated abrasive particles 5 slide down the sand slide plate 15 to the sand outlet 17. At this point, high-pressure gas generated by the air compressor is fed into the gas cylinder 22 via the gas inlet pipe 21. Simultaneously, the cylinder pressure sensor 20 monitors the pressure within the cylinder 22 in real time to ensure safety. The high-pressure gas in the cylinder 22 is delivered to the sand outlet 17 via the erosion pressure pipe 19, pressurizing the abrasive particles 5. These pressurized particles are then delivered to the spray gun 29 via the high-pressure abrasive particle 5 pipeline.

[0080] Jet Erosion: A spray gun 29 is secured by a gun bracket 28 and equipped with an erosion temperature sensor 25, an erosion flow sensor 26, and an erosion pressure sensor 27 to monitor the temperature, flow rate, and pressure of the abrasive particles 5 during the spraying process. The collected parameter data is fed back to the control system in real time to monitor the spraying status. Subsequently, the abrasive particles 5 are sprayed at high speed onto the surface of the sample 35 through the nozzle 30, achieving erosion of the sample 35.

[0081] Nondestructive Monitoring: A protective cover 34 is installed within the erosion chamber to protect the surrounding environment and personnel. Nondestructive testing equipment, including an infrared damage detector 31, a high-speed camera 32, and an acoustic emission instrument, is also located within the chamber to monitor the sample 35's temperature distribution, surface morphology, and damage progression in real time. Data collected by these nondestructive testing devices is also fed back to the control system for evaluating the erosion effect and test results.

[0082] Supporting and Adjusting Sample 35: Sample 35 is mounted on a sample stage 36, which is connected to a telescopic motor 38 via a telescopic bracket 37. This bracket, driven by the telescopic motor 38, moves the sample stage 36 up and down to adjust the height of the sample 35 relative to the nozzle 30. The control system controls the telescopic motor 38 according to test requirements, adjusting the position of the specimen 11 in real time.

[0083] System Control and Data Output: The entire erosion system is centrally controlled by a control system within control cabinet 1. This control system collects signals from various sensors in real time and, by controlling the air compressor and heating system 2, adjusts parameters such as injection pressure, flow rate, and the temperature of the abrasive particles 5, thereby precisely controlling the erosion test process. Upon completion of the erosion test, the control system outputs the test results through a human-machine interface, facilitating analysis and evaluation of the test process and results.

[0084] In summary, the erosion device provided in the embodiment of the present invention is configured to place the sample to be eroded on a sample stage, heat the abrasive particles used for the sample erosion operation to a preset temperature using a heating system, and then spray the heated abrasive particles through the nozzle of a spray gun onto the surface of the sample through a spray system to perform the erosion operation. During operation, the sample status information of the sample is monitored in real time by a detection system. During operation of the entire device, the operating status of the spray system and the heating system is controlled by a control system. The device can simulate and precisely control the erosion speed, flow rate, height, and temperature of the abrasive particles, providing a more efficient and accurate experimental platform for testing the erosion performance of materials. It can simulate the erosion effect of abrasive particles in a real working environment and ensure the reliability and accuracy of experimental data through precise control of parameters such as temperature, pressure, and flow rate.
