[0002] Lightly burned magnesium oxide is a very important basic magnesium raw material, and the current demand for magnesium oxide is increasing. As the demand for magnesium oxide series products gradually changes from low quality to high quality, the performance requirements for magnesium oxide insulation materials are also getting higher and higher.

[0003] In the existing scheme, when manufacturing high-performance magnesium oxide products, the magnesium oxide insulating material is usually formed by directly using ground magnesium oxide particles. However, since magnesium oxide crystals (particles) are square, when they are crushed by grinding, the crushed magnesium oxide crystals usually have sharp edges and corners, which leads to poor fluidity and poor mixing effect when mixed with other additives, thereby reducing the performance of the magnesium oxide product. Summary of the invention

[0027] 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.

[0028] 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.

[0029] 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.

[0030] In order to better understand the magnesium oxide particle shaping method provided in the embodiment of the present application, the existing magnesium oxide particle shaping method is first briefly introduced below. Due to the wide application of magnesium oxide particles in insulation scenarios, for example, magnesium oxide particles are used as an insulating layer to insulate cables. In the existing scheme, when manufacturing magnesium oxide insulating materials, fused magnesia sand is usually ground to obtain magnesium oxide particles, and then the magnesium oxide particles are directly mixed with additives and calcined to obtain magnesium oxide insulating materials. However, since the magnesium oxide crystals (particles) are square, when they are crushed, the crushed magnesium oxide crystals usually have sharp edges and corners, etc. Therefore, the fluidity of the magnesium oxide particles obtained after directly grinding the fused magnesia sand is poor, so the magnesium oxide particles are shaped. In the existing scheme, when magnesium oxide particles are shaped, flat grinding or extremely high temperature calcination (temperature exceeding the melting point of magnesium oxide 2852 degrees Celsius) is usually adopted. When the flat grinding method is used for shaping, the magnesium oxide particles cannot be accurately shaped. The extremely high temperature calcination method has extremely high requirements on equipment, resulting in high costs, which is not conducive to large-scale application of magnesium oxide shaping.

[0031] In order to solve the above-mentioned technical problems, an embodiment of the present application provides a magnesium oxide particle shaping method, which can use the external shape characteristics of the magnesium oxide particles to determine the shaping strength information, and determine the control parameters based on the shaping strength information and the initial state of the magnesium oxide particle group when entering the shaping system. The shaping is performed by controlling the shaping system through the control parameters, thereby improving the roundness and sphericity of the shaped magnesium oxide particles, thereby improving the performance of the manufactured magnesium oxide product.

[0032] See also Figure 1 , Figure 1 A schematic diagram of a magnesium oxide particle shaping system is provided for an embodiment of the present application. Figure 1 As shown, the magnesium oxide particle shaping system includes a pneumatic transmission channel 1, a processing device 2, a shaping device 3, and a camera 4. The output port of the pneumatic transmission channel 1 is connected to the input port of the shaping device 3, the control port of the shaping device 3 is connected to the control port connected to the processing device 2, and the camera 4 is connected to the processing device 2. The camera 4 can be set at the discharge port of the pneumatic transmission channel 1 or the feed port of the shaping device 3. The camera 4 can be used to collect multiple images of the initial magnesium oxide particle group transmitted to the inlet of the magnesium oxide particle shaping system to obtain a first image set. The processing device 2 determines the appearance feature information of k reference magnesium oxide particles based on the first image set to obtain a first appearance feature information set, and then determines the first target shaping intensity information based on the first appearance feature information set, as well as the shaping control parameters of the magnesium oxide particle shaping system based on the first target shaping intensity information and the initial state information of the initial magnesium oxide particle group at the inlet of the magnesium oxide particle shaping system. The processing device 2 controls the shaping device 3 to shape the initial magnesium oxide particles according to the shaping control parameters to obtain target magnesium oxide particles, so that the shaping control parameters can be set specifically for the input initial magnesium oxide particle group to perform shaping processing on it, thereby improving the accuracy of the shaping processing of the magnesium oxide particles.

[0033] Therefore, by precisely shaping the initial magnesium oxide particle group, magnesium oxide particles with higher sphericity can be obtained, so that the fluidity of the magnesium oxide particles when mixed with the mixture is higher, and the mixing degree of the final mixture is improved, thereby improving the insulation performance of the magnesium oxide material produced subsequently.

[0034] See also Figure 2 , Figure 2 A schematic diagram of the planar structure of a shaping device 3 is provided for the embodiment of the present application. Figure 2As shown, the shaping device 3 includes a control module 31, a rotor 32, a first blade 33, a second blade 34 and a material receiving part 35, wherein the rotor 32 is arranged inside the material receiving part, the rotor 32 is connected to the control module, the rotor 32 connecting member is connected to the first blade 33, and the connection point between the rotor 32 connecting member and the first blade 33 can move relative to the rotating shaft of the rotor 32 (that is, the connecting member can be controlled to extend to control the rotation radius of the tip of the first blade 33 away from the rotating shaft), and the inner wall of the material receiving part 35 is provided with a second blade 34, the length of which can be 1-2cm, and the single blades of the first blade 33 and the second blade 34 are staggered. The control module 31 can control the rotation speed of the rotor 32 and the distance between the tips of the first blade 33 and the second blade 34. By controlling the rotation speed of the rotor 32 and the distance between the tips of the first blade 33 and the second blade 34, shaping with different shaping intensities can be achieved, so that the sphericity and roundness of the magnesium oxide particles in the second magnesium oxide particle group obtained by shaping can be more accurately controlled.

[0035] See also Figure 3 , Figure 3 A schematic flow chart of a magnesium oxide particle shaping method is provided for the embodiment of the present application. Figure 3 As shown, in the processing equipment used in the magnesium oxide particle shaping system, the magnesium oxide particle shaping method includes:

[0036] 301. Acquire multiple images of an initial magnesium oxide particle group being transported to a feed inlet of a magnesium oxide particle shaping system through a pneumatic transmission channel to obtain a first image set.

[0037] The diameter of the initial magnesium oxide particle group passing through the pneumatic transmission channel may range from 0.0425 mm to 0.425 mm. When the initial magnesium oxide particles are pneumatically transmitted, the initial magnesium oxide particles may be suspended in the air and transmitted along the direction of the air flow, and the initial magnesium oxide particle group enters the shaping device through the discharge port of the pneumatic transmission channel.

[0038] A plurality of cameras are arranged at the inlet of the magnesium oxide particle shaping system. The cameras may be high-definition cameras, high-definition infrared cameras, etc., which can collect high-definition images at the inlet of the magnesium oxide particle shaping system. 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 initial magnesium oxide particles are distributed in three dimensions at the inlet of the magnesium oxide particle shaping system, the cameras can capture images from multiple angles to obtain multiple first images and form a first image set.

[0039] Since magnesium oxide particles are usually in the form of granular powder after being made through a manufacturing process, pneumatic conveying can be used for conveying them.

[0040] 302. Determine shape feature information of k reference magnesium oxide particles according to the first image set to obtain a first shape feature information set.

[0041] A three-dimensional distribution model of the initial magnesium oxide particle group during pneumatic transmission can be constructed based on the first image set, and the three-dimensional model can be a three-dimensional distribution model at the inlet of the magnesium oxide particle shaping system. The method of constructing the three-dimensional distribution model based on the first image set can adopt an existing three-dimensional model construction method, such as using professional three-dimensional modeling software or using voxel modeling to construct the three-dimensional distribution model, and this application does not limit this.

[0042] By using the first image set to construct a three-dimensional distribution model, the diameter distribution information of the initial magnesium oxide particle group can be further determined based on the three-dimensional distribution model, thereby determining the central diameter based on the diameter distribution information, and then determining k reference magnesium oxide particles based on the central diameter, so as to extract the appearance feature information of the k reference magnesium oxide particles from the three-dimensional distribution model to obtain a first appearance feature information set.

[0043] The first shape feature information set may include one or more first shape feature information, and the first shape feature information can be used to indicate the feature information of the reference magnesium oxide particles in terms of shape. It should be noted that, at a microscopic scale, the shape of the magnesium oxide particles may be an irregular polyhedron, a flaky structure, or a block structure, etc., and the shape of the magnesium oxide particles that have not been specially treated may be relatively rough and the surface is uneven. By adopting the magnesium oxide particle shaping method provided in the embodiment of the present application, the magnesium oxide particle group can be subjected to a specific shaping treatment so that the treated magnesium oxide particles can have a more regular and uniform shape, such as an approximately spherical shape, etc., and the present application does not limit this.

[0044] 303. Determine first target shaping intensity information according to the first shape feature information set.

[0045] The angular information of each reference magnesium oxide particle can be determined through each first shape feature information in the first shape feature information set, so as to further determine the shaping strength information corresponding to the shaping process required according to the angular information of each reference magnesium oxide particle, and then determine the first target shaping strength information of the magnesium oxide particle shaping system according to the shaping strength information set.

[0046] The first target shaping strength information may be the shaping strength information corresponding to the magnesium oxide particle shaping system involved in the embodiment of the present application. The shaping strength information may include but is not limited to collision frequency information, collision force information, pressure strength information, etc., and the present application does not limit this.

[0047] 304. Determine shaping control parameters of the magnesium oxide particle shaping system according to the first target shaping intensity information and the initial state information of the initial magnesium oxide particle group at the inlet of the magnesium oxide particle shaping system.

[0048] By obtaining the initial state information of the initial magnesium oxide particle group at the inlet of the magnesium oxide particle shaping system, such as obtaining the first velocity and air flow rate information at the inlet of the initial magnesium oxide particle group entering the magnesium oxide particle shaping system, the initial state information can be further combined with the first target shaping intensity information to determine the shaping control parameters of the magnesium oxide particle shaping system.

[0049] The shaping control parameters can be used to indicate the relevant control parameters used in the magnesium oxide particle shaping system to shape the magnesium oxide particles. The shaping control parameters may include but are not limited to rotation speed, temperature, shaping time, etc., which are not limited in this application.

[0050] This application is explained by taking the initial state information including the first speed and air flow rate information at the inlet of the initial magnesium oxide particle group entering the magnesium oxide particle shaping system as an example, which does not constitute a limitation on this application. Optionally, the initial state information corresponding to the initial magnesium oxide particle group may also include but is not limited to the size distribution, shape characteristics, density, hardness, etc. of the initial magnesium oxide particle group. The server can also perform further detailed analysis of the above initial state information, and combine the first target shaping intensity information with the initial state information, while considering the characteristics and adjustable parameters of the magnesium oxide particle shaping system, and then find the best shaping control parameter combination that can achieve the first target shaping intensity, which is not limited by this application.

[0051] 305. A shaping control parameter is used to control a magnesium oxide particle shaping system to shape an initial magnesium oxide particle group to obtain a target magnesium oxide particle group.

[0052] After the shaping control parameters are determined, the shaping control parameters can be used to control the magnesium oxide particle shaping system, thereby implementing the step of shaping the initial magnesium oxide particle group, and then obtaining a target magnesium oxide particle group that meets the requirements.

[0053] The target magnesium oxide particle group can be used to indicate the magnesium oxide particle group that meets the morphological requirements after the shaping process. It is understandable that the service end can use the shaping control parameters to control the magnesium oxide particle shaping system, and perform shaping on part of the initial magnesium oxide particle group (such as the first sample magnesium oxide particle group) in the initial magnesium oxide particle group to obtain the shaped magnesium oxide particle group. If the shaped magnesium oxide particle group meets the expected morphological requirements, the service end can use the shaping control parameters to shape the remaining initial magnesium oxide particle group to obtain the target magnesium oxide particle group; if the shaped magnesium oxide particle group does not meet the expected morphological requirements, the service end can repeat the aforementioned steps of determining the shaping control parameters to adjust the shaping control parameters, so that the shaped magnesium oxide particle group can meet the expected morphological requirements through the adjusted shaping control parameters, thereby obtaining the target magnesium oxide particle group, and the present application does not limit this.

[0054] In this example, a first image set is obtained by collecting multiple images of the initial magnesium oxide particle group being transmitted to the inlet of the magnesium oxide particle shaping system, and then the shape feature information of k reference magnesium oxide particles can be determined based on the first image set to obtain a first shape feature information set, and then the first target shaping intensity information can be determined based on the first shape feature information set, and the shaping control parameters of the magnesium oxide particle shaping system can be determined based on the first target shaping intensity information and the initial state information of the initial magnesium oxide particle group at the inlet of the magnesium oxide particle shaping system. Therefore, the magnesium oxide particle shaping system can be controlled to shape the initial magnesium oxide particles according to the shaping control parameters to obtain target magnesium oxide particles, and then the shaping control parameters can be set specifically for the input initial magnesium oxide particle group to shape it, thereby improving the accuracy of the shaping of the magnesium oxide particles.

[0055] In a possible implementation, a method for determining shape feature information of k reference magnesium oxide particles according to a first image set to obtain a first shape feature information set includes:

[0056] A1. constructing a three-dimensional distribution model of the initial magnesium oxide particle group during pneumatic transmission according to the first image set;

[0057] A2. Determine the diameter distribution information of the initial magnesium oxide particle group according to the three-dimensional distribution model;

[0058] A3. Determine the center diameter from the diameter distribution information;

[0059] A4. Determine k reference magnesium oxide particles according to the central diameter;

[0060] A5. Extract shape feature information of k reference magnesium oxide particles from the three-dimensional distribution model to obtain a first shape feature information set.

[0061] The three-dimensional distribution model may be a distribution model constructed according to various distribution forms of the first image set during the pneumatic transmission process. Optionally, the method for constructing the three-dimensional distribution model according to the first image set may adopt an existing three-dimensional model construction method, such as using professional three-dimensional modeling software or using voxel modeling to construct the three-dimensional distribution model, which is not limited in this application.

[0062] The diameter distribution information of the initial magnesium oxide particle group may be information related to the diameter distribution of each initial magnesium oxide particle in the initial magnesium oxide particle group. The server may obtain the position, size and other related data of each initial magnesium oxide particle in the three-dimensional distribution model to further process these data using mathematical algorithms and statistical methods. For example, the diameter distribution information of the initial magnesium oxide particle group may be calculated using methods such as histogram analysis or probability density function fitting, and this application does not limit this.

[0063] The central diameter can be used to indicate a diameter value that is representative in the diameter distribution information of the initial magnesium oxide particle group or that can reflect the characteristics of the entire diameter distribution. The central diameter can be determined based on the diameter distribution information by arithmetic mean method, median method, mode method or weighted average method, and this application does not limit this.

[0064] The service end can determine a reasonable diameter range based on the central diameter, and select a magnesium oxide particle with a diameter value closer to the central diameter within the diameter range, so as to determine the magnesium oxide particle as the reference magnesium oxide particle. Wherein, k can be any positive integer, and this application does not limit this.

[0065] After determining k reference magnesium oxide particles, the server may further extract the appearance feature information of the k reference magnesium oxide particles from the three-dimensional distribution model to obtain a first appearance feature information set, which is not limited in the present application.

[0066] In this example, the server can construct a three-dimensional distribution model of the initial magnesium oxide particle group during pneumatic transmission based on the first image set, and further determine the diameter distribution information of the initial magnesium oxide particle group based on the three-dimensional distribution model, and determine the central diameter from the diameter distribution information, so that k reference magnesium oxide particles can be determined based on the central diameter, and then the shape feature information of the k reference magnesium oxide particles can be extracted from the three-dimensional distribution model to obtain a more representative first shape feature information set, which is beneficial in the subsequent steps. Based on the first shape feature information set, more accurate first target shaping intensity information can be determined to improve the accuracy of the shaping process on the magnesium oxide particles.

[0067] In a possible implementation, a method for determining first target shaping strength information according to a first shape feature information set includes:

[0068] B1. Determine the angular information of the corresponding reference magnesium oxide particles according to the first shape feature information set to obtain an angular information set;

[0069] B2. Determine the shaping strength information of the corresponding reference magnesium oxide particles according to the edge angle information set to obtain a shaping strength information set;

[0070] B3. Determine the first target shaping intensity information of the magnesium oxide particle shaping system according to the shaping intensity information set.

[0071] The angular information set may include angular information of one or more reference magnesium oxide particles, and the angular information may be used to describe the outline characteristics of the reference magnesium oxide particles. Optionally, the angular information may include, but is not limited to, the sharpness of the angularity, the number of angularity, the distribution of the angularity on the magnesium oxide particles, the regularity of the angularity, etc., and this application does not limit this.

[0072] The shaping intensity information set may include shaping intensity information of one or more reference magnesium oxide particles, and the shaping intensity information may be used to describe the relevant information of the intensity of the shaping effect applied when the reference magnesium oxide particles are shaped. The shaping intensity information may include but is not limited to collision frequency information, collision force information, pressure intensity information, etc., and this application does not limit this.

[0073] The server can establish an association model between angular information and shaping strength to determine the association between angular information and shaping strength, for example, determine what strength of shaping strength is required for sharp edges, what strength of shaping strength is required for rounded edges, etc., so as to quantitatively evaluate the angular information of each reference magnesium oxide particle. This application does not impose any restrictions on this.

[0074] The first target shaping strength information may be the shaping strength information corresponding to the magnesium oxide particle shaping system involved in the embodiment of the present application. The server may perform statistical analysis on each shaping strength information in the shaping strength information set, such as calculating statistical quantities such as the mean, median, mode, etc., to understand the central trend of the shaping strength, and further select the shaping strength suitable for the magnesium oxide particle shaping system provided in the embodiment of the present application in combination with specific needs and expected effects, so as to obtain the first target shaping strength information, which is not limited in the present application.

[0075] In this example, the server can determine the angular information of the corresponding reference magnesium oxide particles based on the first shape feature information set to obtain an angular information set, and determine the shaping strength information of the corresponding reference magnesium oxide particles based on the angular information set to obtain a shaping strength information set, so that the first target shaping strength information of the magnesium oxide particle shaping system can be determined based on the shaping strength information set, which is beneficial in subsequent steps to determine more accurate shaping control parameters based on the first target shaping strength information, so as to improve the accuracy of the shaping process on the magnesium oxide particles.

[0076] In a possible implementation, a method for determining shaping strength information of corresponding reference magnesium oxide particles according to an edge information set to obtain a shaping strength information set includes:

[0077] C1. Determine the target shaping sphericity information of the corresponding reference magnesium oxide particles according to the edge angle information set to obtain the target shaping sphericity information set, and determine the target shaping roundness information of the corresponding reference magnesium oxide particles according to the edge angle information set to obtain the target shaping roundness information set;

[0078] C2, obtaining a first deviation value between each target shaping sphericity information in the target shaping sphericity information set and the corresponding current sphericity information to obtain a first deviation value set, and obtaining a second deviation value between each target shaping roundness information in the target shaping roundness information set and the corresponding current roundness information to obtain a second deviation value set;

[0079] C3. Determine the shaping intensity information of the corresponding reference magnesium oxide particles according to the first deviation value in the first deviation value set and the corresponding second deviation value to obtain a shaping intensity information set.

[0080] Among them, the target shaping sphericity information set may include one or more target shaping sphericity information, and the target shaping sphericity information can be used to describe the relevant index information of the sphericity degree expected to be achieved by the magnesium oxide particles after the shaping process. Optionally, the target shaping sphericity information can be directly expressed by a numerical value, such as a sphericity value can be a numerical value between 0 and 1, and the closer to 1, the closer the particle shape is to a perfect sphere. Optionally, the target shaping sphericity information can also be described relatively, such as high sphericity, medium sphericity, low sphericity, etc., to qualitatively indicate the level of sphericity, and this application does not limit this.

[0081] The target shaping roundness information set may include one or more target shaping roundness information, which may be used to describe the relevant index information of the desired roundness of the magnesium oxide particles after shaping, and the present application does not limit this. Optionally, the representation of the target shaping roundness information may be the same as or different from the representation of the aforementioned target shaping sphericity information, and the present application does not limit this.

[0082] The first deviation value may be the difference between each target shaping sphericity information and the corresponding current sphericity information. The second deviation value may be the difference between each target shaping roundness information and the corresponding current roundness information.

[0083] It is understandable that in some applications such as material filling and catalyst carriers, particles with good sphericity may have better fluidity, filling properties and reactivity. Therefore, the present application compares and analyzes the first deviation value and the second deviation value of each reference magnesium oxide particle to obtain a more accurate set of shaping strength information, so that the magnesium oxide particles can become a target magnesium oxide particle group with better performance and better satisfaction after the subsequent shaping process. The present application does not impose any restrictions on this.

[0084] In this example, the server determines the target shaping sphericity information of the corresponding reference magnesium oxide particles based on the edge information set to obtain the target shaping sphericity information set, and determines the target shaping roundness information of the corresponding reference magnesium oxide particles based on the edge information set to obtain the target shaping roundness information set, so as to obtain the first deviation value between each target shaping sphericity information in the target shaping sphericity information set and the corresponding current sphericity information to obtain the first deviation value set, and obtain the second deviation value between each target shaping roundness information in the target shaping roundness information set and the corresponding current roundness information to obtain the second deviation value set, and then the shaping strength information of the corresponding reference magnesium oxide particles can be determined according to the first deviation value in the first deviation value set and the corresponding second deviation value, so as to obtain a more accurate and more satisfactory shaping strength information set, thereby improving the accuracy of the shaping process of the magnesium oxide particles.

[0085] In one possible implementation, a method for determining shaping control parameters of a magnesium oxide particle shaping system according to first target shaping intensity information and initial state information of an initial magnesium oxide particle group entering a feed inlet of the magnesium oxide particle shaping system includes:

[0086] D1. Extracting the first velocity and air velocity information of the initial magnesium oxide particle group entering the inlet of the magnesium oxide particle shaping system from the initial state information;

[0087] D2, determining first collision information between the initial magnesium oxide particle group entering the magnesium oxide particle shaping system and the first blade of the magnesium oxide particle shaping system in a stationary state according to the first speed and air flow rate information;

[0091] D6. Determine shaping control parameter information based on the operating parameter information.

[0092] The first speed can be used to describe the speed at which the initial magnesium oxide particle group enters the inlet of the magnesium oxide particle shaping system. The first speed can be obtained by a specific measuring instrument (such as a laser velocimeter, etc.) or method, and the present application does not limit this.

[0093] The air velocity information can be used to describe the air flow velocity in the system when the initial magnesium oxide particle group enters the feed port of the magnesium oxide particle shaping system. The specific numerical value of the air velocity information can be measured and obtained using corresponding measuring instruments, such as anemometers, etc., and the present application does not limit this. In the magnesium oxide particle shaping system, the air velocity may have a certain effect on the shaping process, for example, the air velocity may affect the dispersion degree of the magnesium oxide particles, heat transfer, and interaction with other substances (such as other magnesium oxide particles), etc., and the present application does not limit this.

[0094] The first collision information may be collision information between an initial group of magnesium oxide particles entering the magnesium oxide particle shaping system using the first speed and air flow rate information and a first blade in a stationary state in the magnesium oxide particle shaping system. The first collision information may include, but is not limited to, collision direction, collision force, and collision speed, etc., and the present application does not limit this.

[0095] The second target shaping intensity information may be shaping intensity information obtained after adjusting the first target shaping intensity information according to the first collision information. It is understandable that the second target shaping intensity information may be more consistent with and more suitable for the current magnesium oxide particle shaping system relative to the first target shaping intensity information, and the present application does not limit this.

[0096] The operating parameter model of the magnesium oxide particle shaping system can be a parameter model constructed based on various attribute information of the magnesium oxide particle shaping system. The attribute information of the magnesium oxide particle shaping system can include but is not limited to the structural dimensions of the system equipment, the shape and number of blades, the power and speed of the motor, the size and position of the feed port and the discharge port, the internal air duct design, etc., and this application does not limit this.

[0097] The server can analyze the various attribute information of the magnesium oxide particle shaping system to determine the key parameters that have a significant impact on the operation of the system, and then establish a mathematical relationship between the key parameters and the system output (such as the particle shaping effect, output, etc.) based on physical principles and engineering experience, and then construct an operating parameter model of the above-mentioned magnesium oxide particle shaping system. This application does not impose any restrictions on this.

[0098] The operating parameter information may be an operating parameter of the magnesium oxide particle shaping system determined based on the operating parameter model and the second target shaping intensity information. The server may input the second target shaping intensity information into the constructed operating parameter model, so as to comprehensively consider the interaction and constraint relationship between various influencing factors through the operating parameter model, and determine the corresponding operating parameter information in combination with the mathematical relationship and algorithm established inside. Optionally, the operating parameter information may include but is not limited to blade speed, feed rate, air flow rate, processing time, etc., which is not limited in this application.

[0099] The server can further integrate the information included in the operating parameter information to obtain more accurate shaping control parameter information that is more in line with the current magnesium oxide particle shaping system, and this application does not impose any restrictions on this.

[0100] In this example, the server extracts the first speed and air flow rate information of the initial magnesium oxide particle group entering the magnesium oxide particle shaping system at the inlet from the initial state information, and can determine the first collision information between the initial magnesium oxide particle group and the first blade of the magnesium oxide particle shaping system in a stationary state after entering the magnesium oxide particle shaping system based on the first speed and air flow rate information, and adjust the first target shaping intensity information based on the first collision information to obtain the second target shaping intensity information, so that an operating parameter model of the magnesium oxide particle shaping system can be constructed based on the attribute information of the magnesium oxide particle shaping system, so as to further determine the operating parameter information of the magnesium oxide particle shaping system based on the operating parameter model and the second target shaping intensity information, and then determine the shaping control parameter information that is accurate and more in line with the current magnesium oxide particle shaping system based on the operating parameter information, thereby improving the accuracy of the shaping process of the magnesium oxide particles.

[0101] For the above embodiments, please refer to Figure 4 , Figure 4A schematic diagram of the structure of a terminal provided in an embodiment of the present application, as shown in the figure, includes a processor, an input device, an output device and a memory, the processor, the input device, the output device and the memory are interconnected, wherein the memory is used to store a computer program, the computer program includes program instructions, the processor is configured to call the program instructions, and the program includes instructions for executing the following steps;

[0105] Determine shaping control parameters of the magnesium oxide particle shaping system according to the first target shaping intensity information and the initial state information of the initial magnesium oxide particle group entering the inlet of the magnesium oxide particle shaping system;

[0106] The shaping control parameters are used to control the magnesium oxide particle shaping system to shape the initial magnesium oxide particle group to obtain the target magnesium oxide particle group.

[0107] In this example, a first image set is obtained by collecting multiple images of the initial magnesium oxide particle group being transmitted to the inlet of the magnesium oxide particle shaping system, and then the shape feature information of k reference magnesium oxide particles can be determined based on the first image set to obtain a first shape feature information set, and then the first target shaping intensity information can be determined based on the first shape feature information set, and the shaping control parameters of the magnesium oxide particle shaping system can be determined based on the first target shaping intensity information and the initial state information of the initial magnesium oxide particle group at the inlet of the magnesium oxide particle shaping system. Therefore, the magnesium oxide particle shaping system can be controlled to shape the initial magnesium oxide particles according to the shaping control parameters to obtain target magnesium oxide particles, and then the shaping control parameters can be set specifically for the input initial magnesium oxide particle group to shape it, thereby improving the accuracy of the shaping of the magnesium oxide particles.
