[0002] Lightly burned magnesium oxide is a very important basic magnesium raw material, and the current demand for magnesium oxide is also increasing.

[0003] In the existing scheme, when removing the electrostatic charge on the surface of magnesium oxide particles, the ion wind generated by the ion blower is usually used to directly blow the magnesium oxide particles to remove the electrostatic charge. Due to the direct blowing, its accuracy is low, which leads to low accuracy in removing the electrostatic charge on the magnesium oxide particles. Summary of the invention

[0034] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0035] The terms "first", "second", etc. in the specification and claims of this application and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally includes steps or units that are not listed, or optionally includes other steps or units inherent to these processes, methods, products or devices.

[0036] Reference to "embodiments" in this application means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0037] In order to better understand the method for removing electrostatic charge on the surface of magnesium oxide particles provided in the embodiment of the present application, the existing method for removing electrostatic charge on the surface of magnesium oxide particles is briefly introduced below. Due to the wide application of magnesium oxide particles in insulation scenarios, for example, magnesium oxide particles are used as a filling material for capacitors to fill capacitors. Since capacitors have high quality requirements for fillers, it can be specifically reflected in that the surface of the filler cannot contain high electrostatic charge. For example, when magnesium oxide particles are used as an insulating layer, the electrostatic charge on its surface will directly determine the insulation performance and service life of the product, etc. Therefore, it is necessary to remove the electrostatic charge. In the existing scheme, when electrostatic charge is removed, ion wind generated by an ion fan is usually used to blow directly on the magnesium oxide particles to remove the electrostatic charge. When the ion fan is used for blowing, the ion wind is usually generated by using a fixed wind speed and a rough estimate of the electrostatic charge on the surface of the magnesium oxide particles, or a fixed adjustment method is used to adjust the number of ions contained in the ion wind to adapt to the electrostatic charge on the surface of the magnesium oxide particles by using ion wind of fixed different ion number levels. The accuracy of the above method in removing electrostatic charge is poor, so that the magnesium oxide after electrostatic removal may not be able to meet all usage requirements, or it needs to be blown by ion wind a large number of times repeatedly to meet the usage requirements, and the energy consumption at this time will be greatly increased.

[0038] In order to solve the above-mentioned technical problems, an embodiment of the present application provides a method for removing electrostatic charges on the surface of magnesium oxide particles. The method can determine a first electrostatic charge by combining the diameter distribution information of the magnesium oxide group and the air load, and a second electrostatic charge determined by the air flow rate and air flow information to determine a target electrostatic charge of the magnesium oxide particles. Finally, the ion wind generation parameter information is determined according to the target electrostatic charge, thereby improving the accuracy of the determined ion wind generation parameter information, and further improving the accuracy of subsequent electrostatic charge removal of the magnesium oxide particles. At the same time, it can also reduce the number of repeated blowing to reduce energy consumption during electrostatic charge removal.

[0039] See also Figure 1 , Figure 1 A schematic diagram of a system for removing electrostatic charge on the surface of magnesium oxide particles is provided for the present application embodiment. Figure 1 As shown, the system for removing electrostatic charge on the surface of magnesium oxide particles includes a charge removal pipeline 1 and an ion blower, and an air outlet 2 ( Figure 1Only the air outlet 2 of the ion fan is shown in the figure, which is arranged on the inner wall of the charge removal pipe 1. The air outlet 2 of the ion fan forms a certain angle with the longitudinal axis of the charge removal pipe 1, which can be an angle between 30 degrees and 50 degrees. The magnesium oxide particle group enters the charge removal pipe 1 through the feed port of the charge removal pipe 1, and is output from the discharge port of the charge removal pipe 1 after the electrostatic charge is removed by the ion wind generated by the ion fan. An electrostatic detection device is provided at the discharge port, which can directly detect the charge of the magnesium oxide particle group output from the discharge port. If the detected charge is lower than the preset electrostatic charge, the magnesium oxide particles are output to the target product. If it is higher than the preset electrostatic charge, the magnesium oxide particle group at the outlet of the charge removal pipe 1 is input into the charge removal pipe 1 again for charge removal, until the electrostatic charge of the magnesium oxide particle group at the outlet of the charge removal pipe 1 is lower than the preset electrostatic charge, and then the magnesium oxide particles are output to the target product. The target product may be, for example, a capacitor to be produced, and the preset electrostatic charge is set by empirical values ​​or historical data, which is an electrostatic charge that meets usage requirements.

[0040] See also Figure 2 , Figure 2 The present invention provides a schematic flow chart of a method for removing electrostatic charge on the surface of magnesium oxide particles. Figure 2 As shown, the method is applied to a system for removing electrostatic charges on the surface of magnesium oxide particles. The system for removing electrostatic charges on the surface of magnesium oxide particles includes a charge removal pipeline 1 and an ion blower. The method includes:

[0041] 201. Acquire a first image set of a magnesium oxide particle group in a first spatial region when the charge removal pipeline 1 is pneumatically transported.

[0042] The diameter of the magnesium oxide particle group may range from 0.0425 mm to 0.425 mm. When the magnesium oxide particles are pneumatically transported, the magnesium oxide particles may be suspended in the air and transported along the direction of the air flow, and the magnesium oxide particle group enters the charge removal pipeline 1 through the feed port of the charge removal pipeline 1.

[0043] A plurality of cameras are arranged on the inner wall of the charge removal pipe 1. The cameras may be high-definition cameras, high-definition infrared cameras, etc., which can collect high-definition images at the first spatial region in the charge removal pipe 1. High-definition images can be understood as images with a resolution higher than a preset resolution threshold, which is set by empirical values ​​or historical data. Since the magnesium oxide particles are distributed in three dimensions in the first spatial region, the camera can capture images from multiple angles to obtain multiple first images and form a first image set.

[0044] The first spatial region is between the feed port of the charge removal pipe 1 and the air outlet 2 of the ion blower, and this region is used to detect the diameter distribution information of the magnesium oxide particle group. Since the magnesium oxide particles are usually in the form of granular powder after being made by the manufacturing process, pneumatic transmission can be used when transmitting them. During pneumatic transmission, since the magnesium oxide particles are solid, they will collide with the transmission pipeline during pneumatic transmission, thereby generating electrostatic charges. Due to the generation of electrostatic charges, the performance of the magnesium oxide particles in subsequent applications will be reduced, so it is necessary to remove the electrostatic charges on its surface at this time. At the same time, due to the different diameters of the magnesium oxide particles, the magnesium oxide particles collide with each other during pneumatic transmission, and the amount of electrostatic charges generated when the magnesium oxide particles collide with the transmission pipeline will also be different. Therefore, it is necessary to obtain the diameter distribution information of the magnesium oxide particles to accurately determine the amount of electrostatic charges of the magnesium oxide particle group.

[0045] 202. Determine group distribution diameter information of the magnesium oxide particle group according to the first image set.

[0046] Among them, the first image in the first image set can be gray-scaled to obtain a first gray-scale image set, and the three-dimensional spatial distribution model of the magnesium oxide particles can be constructed using the first gray-scale image set, and finally the diameter distribution information of the magnesium oxide particles can be determined based on the three-dimensional spatial distribution model. Since the magnesium oxide particle group is three-dimensionally distributed, if the plane image is directly used to determine the diameter distribution information, occlusion will occur, thereby reducing the actual number of magnesium oxide particle diameters that can be obtained. Therefore, by constructing a three-dimensional spatial distribution model of the magnesium oxide particle group through the first image set, and determining the diameter distribution information from the three-dimensional spatial distribution model, the accuracy of determining the diameter distribution information can be greatly improved.

[0047] Specifically, since the regions where magnesium oxide particles of different diameters are located will be quite different, regional clustering can be performed. Since the diameter of magnesium oxide particles is very small, an extremely high-definition camera device is required for video processing. At the same time, due to the resolution limitation of the camera device itself, some magnesium oxide particles will be misjudged as pixels, or magnesium oxide particles with a diameter less than a certain threshold will be judged as pixels of a large-diameter magnesium oxide particle. At this time, it is necessary to perform preliminary clustering processing on the pixels to obtain multiple types of pixel types. For example, the pixels of large-diameter magnesium oxide particles, the pixels of small-diameter magnesium oxide particles, magnesium oxide particles that are judged as single pixels, and smaller magnesium oxide particles that cannot be defined by pixels. Such magnesium oxide particles are too small in diameter. During screening, if the magnesium oxide particles that are much larger than their diameter in the diameter distribution information can be screened, they can usually flow into the discharge port with the airflow. Therefore, the influence of such magnesium oxide particles can be ignored.

[0048] The first image in the first image set can be gray-scaled to obtain a first gray-scale image. Then, the magnesium oxide particles in each first gray-scale image are position-corrected to obtain the three-dimensional position information of the magnesium oxide particles and the three-dimensional shape of the magnesium oxide particles. A three-dimensional spatial distribution model is constructed based on the three-dimensional position information of the magnesium oxide particles and the three-dimensional shape of the magnesium oxide particles. Among them, a general position correction and three-dimensional shape construction method can be used to obtain the three-dimensional position information of the magnesium oxide particles and construct the three-dimensional shape.

[0049] The maximum endpoint distance of the magnesium oxide particles in the three-dimensional spatial distribution model can be determined as the diameter of the magnesium oxide particles, thereby obtaining a first diameter set. The diameter distribution information of the first diameter set can be constructed using a general method for constructing distribution information based on diameter information, thereby obtaining group distribution diameter information of the magnesium oxide particle group.

[0050] 203. Determine a first electrostatic charge amount of the magnesium oxide particle group according to the group distribution diameter information and the air load amount when the magnesium oxide particle group is pneumatically transported in the charge removal pipeline 1.

[0051] Since the diameter of the magnesium oxide particles is in different diameter categories when the magnesium oxide particle group is pneumatically transmitted, its position in the airflow will also be relatively concentrated. Therefore, the diameter in the diameter distribution information of the magnesium oxide particle group can be clustered to obtain multiple categories, and then the category diameter of each category is determined, and a reference electrostatic charge is determined using the category diameter and the corresponding number of particles, and another reference electrostatic charge is determined using the air load, and finally the two reference electrostatic charges are weighted to obtain the first electrostatic charge. Therefore, the first electrostatic charge can be determined in combination with the diameter of the magnesium oxide particles and the air load, which improves the accuracy of the first electrostatic charge when it is determined.

[0052] 204. Obtain air velocity and air flow information when the magnesium oxide particle group is pneumatically transported in the charge removal pipeline 1.

[0053] Among them, the air flow rate can be measured by a flow rate measuring device. The air flow information may include first gas flow direction information. The first gas flow direction information can be understood as the flow direction of air in the charge removal pipe 1. When the magnesium oxide particle group is input into the charge removal pipe 1, the magnesium oxide particle group is usually input into the charge removal pipe 1 using the wind direction along the axial direction of the charge removal pipe 1. Therefore, the first gas flow direction at this time may be along the axial direction of the charge removal pipe 1. During subsequent transmission, if no other wind force is added, it can be approximately regarded as the airflow will always move along the axial direction of the charge removal pipe 1.

[0054] 205. Determine a second electrostatic charge amount according to the air flow velocity and the air flow information.

[0055] Among them, the first gas flow direction information in the charge removal pipe 1 can be determined based on the air flow information. When the magnesium oxide particles are transmitted along the charge removal pipe 1 along the wind direction, the magnesium oxide particles will move in the vertical direction due to the effect of gravity. At this time, due to the influence of air drag and gravity, collisions will occur between the magnesium oxide particles, and collisions will occur between the magnesium oxide particles and the inner wall of the charge removal pipe 1. Due to the occurrence of collisions, the electrons on the surface of the magnesium oxide particles will increase or be lost, thereby generating electrostatic charges. In this way, the first collision information between the magnesium oxide particle group and the inner wall of the charge removal pipe 1 and the second collision information between the magnesium oxide particles in the magnesium oxide particle group can be determined based on the first gas flow direction information and the air flow rate. When magnesium oxide particles collide with each other, since they are all magnesium oxide, the electrostatic charge generated by the collision will be much lower than the electrostatic charge generated by the collision between the magnesium oxide particles and the inner wall of the charge removal pipe 1 (the materials of the magnesium oxide particles and the inner wall of the charge removal pipe 1 are usually different). Therefore, the second reference electrostatic charge can be determined based on the first collision information, and the charge correction information can be determined based on the second collision information. The second reference electrostatic charge can be corrected using the correction information to obtain the second electrostatic charge, which can improve the accuracy of determining the second electrostatic charge.

[0056] 206. Determine a target electrostatic charge of the magnesium oxide particle group according to the first electrostatic charge and the second electrostatic charge.

[0057] The sum of the first electrostatic charge amount and the second electrostatic charge amount may be determined as the target electrostatic charge amount.

[0058] 207. Determine ion wind generation parameter information of the ion blower according to the target charge amount and the air flow information.

[0059] Among them, since the ion wind generated by the ion fan has wind speed and ion quantity, the ion wind generated by the ion fan will affect the first gas flow direction, so that after the ion wind is added, the gas flow direction in the charge removal pipeline 1 will change. Therefore, when determining the ion wind generation parameter information, it is necessary to consider the influence of the ion wind on the original airflow, and then the first gas flow direction information determined by the air flow information and the wind outlet direction information of the ion fan can be determined according to the second gas flow direction information of the ion wind generated by the ion fan when the magnesium oxide particle group is pneumatically transmitted in the charge removal pipeline 1. The second gas flow direction will change with the flow velocity of the ion wind. In this way, the flow velocity and flow direction curve between the second gas flow direction and the ion wind flow velocity can be obtained, and then the flow velocity and flow direction curve is used to generate the charge amount adjustment factor, and finally the target charge amount is adjusted according to the charge amount adjustment factor to obtain the final ion amount that the ion fan needs to generate, and the corresponding ion wind speed. The ion amount and ion wind speed are determined as the ion wind generation parameter information. Therefore, the ion wind blower can be controlled by the parameters corresponding to the ion wind generation parameter information to use the corresponding ion wind speed and generate the corresponding ion quantity to remove the charge of the magnesium oxide particles.

[0060] In this example, a first image set of a magnesium oxide particle group at a first spatial region when the magnesium oxide particle group is pneumatically transported in the charge removal pipe 1 is obtained, group distribution diameter information of the magnesium oxide particle group is determined according to the first image set, a first electrostatic charge of the magnesium oxide particle group is determined according to the group distribution diameter information and the air load when the magnesium oxide particle group is pneumatically transported in the charge removal pipe 1, an air flow rate and air flow information when the magnesium oxide particle group is pneumatically transported in the charge removal pipe 1 are obtained, a second electrostatic charge is determined according to the air flow rate and air flow information, and a second electrostatic charge is determined according to the first electrostatic charge. The target electrostatic charge of the magnesium oxide particle group is determined by the electrostatic charge and the second electrostatic charge, and the ion wind generation parameter information of the ion blower is determined according to the target charge and the air flow information. Therefore, the diameter distribution information of the magnesium oxide group and the air load can be combined to determine the first electrostatic charge, and the air flow rate and the air flow information can be used to determine the target electrostatic charge of the magnesium oxide particles. Finally, the ion wind generation parameter information is determined according to the target electrostatic charge, which improves the accuracy of the determined ion wind generation parameter information, thereby improving the accuracy of the subsequent electrostatic charge removal of the magnesium oxide particles.

[0061] In one possible implementation, a method for determining a first electrostatic charge of the magnesium oxide particle group according to the group distribution diameter information and the air load when the magnesium oxide particle group is pneumatically transported in the charge removal pipeline 1 includes:

[0062] A1. Perform diameter distribution clustering processing based on group distribution diameter information to obtain k diameter categories;

[0063] A2. Determine the category diameters according to the diameters in the k diameter categories, and obtain k first category diameters;

[0064] A3, determining a first reference electrostatic charge amount generated when the magnesium oxide particles collide during pneumatic transmission according to k diameters of the first category and the number of corresponding magnesium oxide particles;

[0065] A4, determining a second reference electrostatic charge according to the air load;

[0066] A5. Perform a weighted operation on the first reference electrostatic charge and the second reference electrostatic charge to obtain the first electrostatic charge.

[0067] Among them, although the diameter of the magnesium oxide particles is within a certain diameter range, within this diameter range, the diameter of the magnesium oxide particles that enter the charge removal pipe 1 each time is randomly distributed within this diameter range. After obtaining the group diameter distribution information, the group distribution diameter information can be clustered to obtain k diameter categories. The diameter category can be understood as determining the diameters concentrated within a certain diameter range as a diameter category.

[0068] The mean diameter in the diameter category can be determined as the category diameter. Since each diameter category includes multiple diameters, there will be differences between the diameters. At the same time, since the final charge removal is performed when the electrostatic charge is lower than the preset charge threshold, the use requirements are met. Therefore, when performing subsequent charge calculations, the mean diameter in the diameter category is determined as the category diameter. This can greatly reduce the amount of calculation when calculating the charge, improve the efficiency of the calculation, and ensure the accuracy of the calculation.

[0069] When the magnesium oxide particles enter the charge removal pipe 1, they are usually processed in batches according to mass. Specifically, it can be understood that the mass of the magnesium oxide particles entering the charge removal pipe 1 each time is approximately the same. At this time, the smaller the diameter of the magnesium oxide particles, the larger the overall surface area of ​​the magnesium oxide particle group, and the greater the amount of electrostatic charge generated after the collision.

[0070] The magnesium oxide particles here will be directly applied to the product after removing the electrostatic charge. There will be a process of grinding the magnesium oxide particles before. After the magnesium oxide particles are ground, their roundness is usually between 0.3-0.7 and their sphericity is usually between 0.3-0.7. At this time, the magnesium oxide particles can be approximated as a sphere similar to an ellipsoid, so that the group surface area of ​​the magnesium oxide particle group can be solved according to the k first category diameters and the corresponding number information of magnesium oxide particles, and then the first reference electrostatic charge is determined according to the mapping relationship between the group surface area and the electrostatic charge. Therefore, the first reference electrostatic charge can be quickly and accurately obtained.

[0071] When the magnesium oxide particles are pneumatically transported, the greater the air load, the more magnesium oxide particles there are. At this time, the probability of the magnesium oxide particles colliding with the inner wall of the charge removal pipe 1 will be reduced, thereby reducing the probability of the magnesium oxide particles causing collisions and generating electrostatic charges, and ultimately leading to a reduction in the electrostatic charge of the magnesium oxide particle group. Therefore, the air load can be determined based on the mass of the magnesium oxide particles input into the charge removal pipe 1 each time, and then a second reference electrostatic charge can be determined based on the air load.

[0072] The weights corresponding to the first reference electrostatic charge and the second reference electrostatic charge can be obtained respectively. The weights are set by empirical values ​​or historical data. Then, the corresponding weights are used to perform weight calculation to obtain the first electrostatic charge.

[0073] In this example, clustering is performed on the diameter distribution information of the magnesium oxide particles to obtain k diameter categories, and the category diameters corresponding to the k diameter categories are calculated respectively. Then, the first reference electrostatic charge is determined based on the category diameters and the corresponding quantities, and the second reference electrostatic charge is determined based on the air load. Finally, a weighted operation is performed based on the first reference electrostatic charge and the second reference electrostatic charge to obtain the first electrostatic charge, thereby improving the accuracy of obtaining the first electrostatic charge.

[0074] In one possible implementation, a method for determining a second electrostatic charge amount according to the air flow rate and the air flow information includes:

[0075] B1. determining first gas flow direction information in the charge removal pipeline 1 according to the air flow information;

[0076] B2. determining first collision information between the magnesium oxide particle group and the inner wall of the charge removal pipe 1 and second collision information between the magnesium oxide particles in the magnesium oxide particle group according to the first gas flow direction information and the air flow rate;

[0077] B3. determining a second reference electrostatic charge according to the first collision information;

[0078] B4. determining charge correction information according to the second collision information;

[0079] B5. Use the charge correction information to correct the second reference electrostatic charge to obtain a second electrostatic charge.

[0080] Among them, the air flow information may include first gas flow direction information. The first gas flow direction information can be understood as the flow direction of air in the charge removal pipe 1. When the magnesium oxide particle group is input into the charge removal pipe 1, the magnesium oxide particle group is usually input into the charge removal pipe 1 in the wind direction along the axial direction of the charge removal pipe 1. Therefore, the first gas flow direction at this time may be along the axial direction of the charge removal pipe 1. During subsequent transmission, if no other wind force is added, it can be approximately regarded that the airflow will always move along the axial direction of the charge removal pipe 1.

[0081] When magnesium oxide particles are transmitted along the charge removal pipe 1 with the wind direction, the magnesium oxide particles are affected by gravity and move in the vertical direction. At this time, due to the drag of the air and the influence of gravity, collisions between magnesium oxide particles and collisions between magnesium oxide particles and the inner wall of the charge removal pipe 1 will occur. Due to the occurrence of collisions, the electrons on the surface of magnesium oxide particles will increase or be lost, thereby generating electrostatic charges. In this way, the air flow rate can be determined as the movement speed value of magnesium oxide particles along the axial direction of the charge removal pipe 1, and the first gas flow direction information is determined as the movement direction of magnesium oxide particles. At this time, the first vertical distance between the magnesium oxide particles in the charge removal pipe 1 and the pipe wall of the charge removal pipe 1, as well as the first length of the charge removal pipe 1, can be combined to determine the initial movement curve of the magnesium oxide particles in the charge removal pipe 1 when they collide with the inner wall of the charge removal pipe 1.

[0082] At the same time, the initial motion curve of the reference magnesium oxide particles can be obtained, and the intersection point of the initial motion curve is determined as the collision point between the magnesium oxide particles. At the collision point, a collision analysis is performed on the two colliding magnesium oxide particles to obtain the collision posture of the two magnesium oxide particles after the collision, and then the motion trajectory after the collision is predicted according to the collision posture until the motion trajectory of the magnesium oxide particles extends to the discharge port of the charge removal pipe 1, thereby obtaining the actual motion curve of the reference magnesium oxide particles (the motion curve can be a motion trajectory curve). Finally, the first collision information and the second collision information are determined according to the actual motion curve. The first collision information may include the collision point and collision force between the magnesium oxide particles and the inner wall of the charge removal pipe 1, and the second collision information includes the collision point and collision force between the magnesium oxide particles. The reference magnesium oxide particles can be magnesium oxide particles randomly selected from each equally divided area after the magnesium oxide particle group is equally divided along the vertical diameter direction according to the charge removal pipe 1. The schematic diagram of the equal division of the charge removal pipe 1 along the vertical diameter direction can be shown as follows. Figure 3 shown.

[0083] When a collision occurs, the magnitude of the collision force will affect the charge transfer capability. As the collision force increases, the charge transfer capability will increase. Therefore, the second reference electrostatic charge can be determined based on the collision point and the collision force in the first collision information. Since the magnesium oxide particles are all magnesium oxide when colliding, the electrostatic charge generated by the collision will be much lower than the electrostatic charge generated by the collision between the magnesium oxide particles and the inner wall of the charge removal pipe 1. Therefore, the charge correction information can be determined based on the collision force between the magnesium oxide particles. Specifically, the charge correction information corresponding to the second collision information can be determined based on the mapping relationship between the collision force and the charge correction information.

[0084] The product of the charge amount correction information and the second reference electrostatic charge amount may be determined as the second electrostatic charge amount.

[0085] In this example, by performing collision analysis on magnesium oxide particles, first collision information and second collision information are obtained, and then the second reference electrostatic charge is determined based on the first collision information, and the charge correction information is determined based on the second collision information. Finally, the second reference electrostatic charge is corrected using the charge correction information to obtain the second electrostatic charge, which can greatly improve the accuracy of obtaining the second electrostatic charge.

[0086] In one possible implementation, a method for determining ion wind generation parameter information of the ion blower according to the target charge amount and the air flow information includes:

[0087] C1. determining first gas flow direction information in the charge removal pipeline 1 according to the air flow information;

[0088] C2. Obtaining the air outlet direction information of the ion fan;

[0089] C3, determining second gas flow direction information when the ion wind generated by the ion blower performs pneumatic transmission on the magnesium oxide particle group in the charge removal pipeline 1 according to the wind outlet direction information and the first gas flow direction information;

[0090] C4, determining a flow velocity and direction curve between the flow velocity of the ion blower and the gas flow direction when the magnesium oxide particle group is pneumatically transported in the charge removal pipeline 1 according to the second gas flow direction information and the flow velocity information of the ion blower;

[0091] C5. determining a charge adjustment factor according to the flow velocity and direction curve;

[0092] C6. Determine ion wind generation parameter information of the ion blower according to the charge adjustment factor and the target charge.

[0093] Among them, after the ion blower is connected and installed with the charge removal pipe 1, its air outlet direction can be fixed. Therefore, the air outlet direction information of the ion blower can be determined according to the installation information, etc. The first gas flow direction information can be understood as the flow direction of air in the charge removal pipe 1. When the magnesium oxide particle group is input into the charge removal pipe 1, the magnesium oxide particle group is usually input into the charge removal pipe 1 in the wind direction along the axial direction of the charge removal pipe 1. Therefore, the first gas flow direction at this time can be along the axial direction of the charge removal pipe 1. In the subsequent transmission, if there is no other wind force added, it can be approximately regarded as that the airflow will always move along the axial direction of the charge removal pipe 1.

[0094] A standard magnesium oxide particle can be set, and the magnesium oxide particle is simultaneously subjected to the airflow corresponding to the outlet direction information (the airflow has multiple initial air flow rates) and the airflow corresponding to the first gas flow direction information, and then the motion trajectory information of the magnesium oxide particle when it moves in the charge removal pipeline 1 is obtained, and then the motion direction indicated by the motion trajectory information is determined as the second gas flow direction information (at this time, multiple second gas flow direction information can be obtained). The standard magnesium oxide can be a magnesium oxide particle with a preset shape and volume that is preset.

[0095] Through multiple second gas flow direction information, flow velocity and flow direction characteristics can be extracted to obtain corresponding characteristic values ​​(characteristic values ​​are flow velocity and flow direction values), and then a flow velocity and flow direction curve can be constructed based on the characteristic values. The corresponding flow direction curve at the preset flow velocity can be obtained, and the charge adjustment factor can be determined based on the difference information between the flow direction curve and the first gas flow direction information. For example, the charge adjustment factor can be determined based on the difference information between the collision information corresponding to the flow direction curve and the collision information corresponding to the first gas flow direction information. Finally, the product of the charge adjustment factor and the target charge is determined as the final amount of ions that the ion blower needs to produce, and the preset flow velocity is determined as the ion wind speed. Of course, it is also possible to optimize the calculation in combination with the operating performance of the ion blower to obtain the charge adjustment factor under the optimal ion wind speed state, and then use the charge adjustment factor to adjust the final amount of ions that the ion blower needs to produce. Of course, since the magnesium oxide particles may have electrostatic charges before being input into the charge removal pipe 1, they can also be corrected to obtain the corrected amount of ions that the ion blower needs to generate, and the corrected amount of ions that the ion blower needs to generate can be determined as the ion wind generation parameter information.

[0096] In this example, since the ion wind from the ion blower will blow in, it is necessary to adjust the target electrostatic charge amount in combination with the parameter information of the ion wind to obtain the final amount of ions that the ion blower needs to generate, thereby further improving the accuracy of charge removal.

[0097] In a possible implementation, after determining the ion wind generation parameter information of the ion blower according to the target charge amount and the air flow information, the method further includes:

[0098] D1, controlling the ion blower to input ion wind into the charge removal pipeline using parameters corresponding to the ion wind generation parameter information;

[0099] D2, detecting a third electrostatic charge amount of the magnesium oxide particle group at the outlet of the charge removal pipeline 1;

[0100] D3. If the third electrostatic charge is higher than the preset electrostatic charge, the magnesium oxide particle group at the outlet of the charge removal pipeline 1 is input into the charge removal pipeline 1 again for charge removal until the electrostatic charge of the magnesium oxide particle group at the outlet of the charge removal pipeline 1 is lower than the preset electrostatic charge;

[0101] D4. If the third electrostatic charge is less than the preset electrostatic charge, the magnesium oxide particles are transported into the target product.

[0102] Among them, the preset electrostatic charge can be set according to the actual demand information for magnesium oxide particles. When the demand is not met once, the magnesium oxide particles can be treated to remove the electrostatic charge again until the actual demand is met. The target product can be a capacitor filled with magnesium oxide particles as a filling material of the capacitor. Since the capacitor has a high quality requirement for the filler, it can be specifically reflected in that the surface of the filler cannot contain a high electrostatic charge. For example, when magnesium oxide particles are used as an insulating layer of the product, its surface electrostatic charge will directly determine the insulation performance and service life of the product.
