[0002] Centrifugal separation is a physical method in the graphite fiber purification process. It uses centrifugal force to separate solid particles from liquid in the mixture. In the graphite purification process, centrifugal separation is usually used to remove lighter impurity minerals in graphite concentrate or to recover graphite in tailings after flotation. In the specific operation process, the graphite concentrate is mixed with an appropriate liquid medium (such as water) to form a suspension, which is then sent to a centrifuge. In the high-speed rotating centrifuge, due to the centrifugal force, the denser graphite particles are pushed to the centrifuge wall, while the lighter impurity minerals are pushed to the center, thereby achieving the separation of graphite and impurities;

[0003] In the process of analyzing the centrifugal effect in the graphite fiber purification process, the prior art is unable to comprehensively analyze and judge the impurity removal effect and the uniformity of particle size during the centrifugal process. At the same time, when judging the impurity removal effect, it is unable to comprehensively judge the impurity removal effect by comprehensively considering the removal of impurities and the retention of graphite, which reduces the accuracy and efficiency of the centrifugal effect analysis and judgment. The above problems exist in the prior art.

[0004] For example, a Chinese patent with application publication number CN113065670A discloses a method for condition maintenance of centrifugal fans in power plants, which includes the following steps: collecting centrifugal fan information; conducting centrifugal fan condition diagnosis and analysis; conducting centrifugal fan condition evaluation; formulating centrifugal fan predictive maintenance suggestions; formulating centrifugal fan maintenance strategies; judging whether to perform maintenance, and when the judgment result is yes, executing the next step, and when the judgment result is no, returning to the initial step; formulating a centrifugal fan maintenance plan; implementing centrifugal fan maintenance; conducting post-maintenance evaluation and continuous improvement of centrifugal fans; and analyzing the benefits of centrifugal fan condition maintenance. The effect is: implementing condition maintenance of centrifugal fans is a concrete manifestation of realizing modernization of equipment management, management innovation, and technological innovation in power generation enterprises. It can effectively overcome the problems of over-repair or disrepair of equipment caused by regular maintenance of centrifugal fans, and improve equipment safety and availability.

[0005] The above patents all have the problems raised by this background technology. In order to solve the problems raised by this background technology, this application designs a centrifugal effect analysis system and method in a graphite fiber purification process. Summary of the invention

[0006] In view of the deficiencies in the prior art, the present invention proposes a centrifugal effect analysis system and method in a graphite fiber purification process.

[0007] To achieve the above object, the present invention provides the following technical solution: a method for analyzing centrifugal effect in a graphite fiber purification process, which comprises the following specific steps:

[0013] It should be noted that the specific steps of obtaining the proportion data of each component of the graphite raw material in the graphite purification process, obtaining the proportion data of each component of the graphite after centrifugation and the shape data of the particles are:

[0014] S11, obtaining the proportion data of each component of the graphite raw material before graphite purification through a component detection device, and storing it in a first storage component;

[0015] S12, after centrifugation, obtaining the proportion data of each component of the centrifuged graphite and the shape data of the particles, wherein the shape data of the particles is the diameter data of the particles, and storing them in the second storage component;

[0016] In this way, the proportion data of each component of the graphite raw material before graphite purification and the proportion data of each component of the graphite after centrifugation are obtained for comparative calculation to obtain the decontamination effect. At the same time, the shape data of the particles are compared with the shape of the standard particles to obtain the uniformity of the particle size, and then the centrifugal effect is analyzed and judged.

[0017] It should be specifically explained here that the acquisition of the proportion data of each component of the graphite raw material and the proportion data of each component of the graphite after centrifugation and importing them into the impurity removal effect evaluation model to evaluate the impurity removal effect includes the following specific steps:

[0018] S21. Obtain the proportion data of each component of the graphite raw material before graphite purification and the proportion data of each component of the graphite after centrifugation, and substitute them into the component removal rate calculation formula to calculate the removal rate of each component, wherein the removal rate calculation formula of the i-th component is: Wherein, mi q is the proportion data of the i-th component of the graphite raw material before graphite purification, and mi h is the proportion data of the i-th component of the graphite raw material after graphite purification;

[0028] It should be specifically explained here that the specific content of the equipment matching warning according to the centrifugal effect analysis result is:

[0029] The obtained centrifugal effect analysis value is compared with the set centrifugal effect analysis threshold. If the centrifugal effect analysis value is greater than or equal to the set centrifugal effect analysis threshold, it means that the centrifugal process is qualified and the centrifugal equipment matches the graphite fiber purification process. If the centrifugal effect analysis value is less than the set centrifugal effect analysis threshold, it means that the centrifugal process is unqualified and the centrifugal equipment does not match the graphite fiber purification process.

[0030] It should be noted here that the method for determining the value of the impurity removal effect abnormal value proportion coefficient, the centrifugal effect analysis threshold and the impurity removal proportion coefficient is as follows: obtain at least 5000 sets of historical graphite purification process graphite raw material proportion data, obtain the proportion data of each component of the graphite after centrifugation and the shape data of the particles, substitute the proportion data of each component of the graphite raw materials in the historical graphite purification process, the proportion data of each component of the graphite after centrifugation and the shape data of the particles into the centrifugal effect analysis value calculation formula to calculate the centrifugal effect analysis value, and at the same time obtain the qualified judgment results of graphite purification corresponding to these data, substitute the calculated centrifugal effect analysis value and qualified judgment results into the fitting software, and output the values ​​of the impurity removal effect abnormal value proportion coefficient, the centrifugal effect analysis threshold and the impurity removal proportion coefficient that meet the highest judgment accuracy.

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.

[0042] Example 1

[0043] In order to solve the technical problems raised in the background technology, the present invention provides a preferred embodiment: Figure 1 As shown, a method for analyzing centrifugal effect in a graphite fiber purification process comprises the following specific steps:

[0044] S1. Obtaining the proportion data of each component of the graphite raw material in the graphite purification process, and obtaining the proportion data of each component of the graphite after centrifugation and the shape data of the particles;

[0045] In one specific embodiment, the specific steps of S1 are: S11, obtaining the proportion data of each component of the graphite raw material before graphite purification through a component detection device, and storing it in a first storage component;

[0046] It should be specifically noted in this embodiment that the component detection equipment is used to analyze the proportion of each component in the graphite raw material before graphite purification, which is crucial for subsequent purification process adjustment and product quality control. Modern analytical instruments, such as X-ray fluorescence spectrometer (XRF), atomic absorption spectrometer (AAS), X-ray diffractometer (XRD) and mass spectrometer, can provide accurate elemental composition and structural analysis data;

[0047] The following is an overview of the composition analysis of graphite raw materials using these devices:

[0048] 1. X-ray fluorescence spectrometer (XRF): It can non-destructively determine the elemental composition and content in the sample. XRF is very effective for quantitative analysis of elements such as silicon, aluminum, and iron in graphite raw materials.

[0049] 2. Atomic Absorption Spectrometer (AAS): Determine the concentration of a specific element in a sample by measuring the intensity of the characteristic absorption light of the element. AAS is suitable for detecting metal elements in graphite raw materials, such as copper, lead, etc.

[0050] 3. X-ray diffractometer (XRD): It can provide crystal structure information of graphite raw materials and determine the crystallinity and orientation of graphite, which is very important for evaluating the physical properties of graphite materials.

[0051] 4. Mass spectrometer: For analyzing organic components in graphite raw materials, such as hydrocarbons, mass spectrometer can provide high-resolution molecular structure information;

[0052] Through these high-precision analysis equipment, detailed data of various components in graphite raw materials can be obtained, including fixed carbon content, volatile matter, ash content, etc. These data will provide a scientific basis for the selection and optimization of graphite fiber purification processes. For example, in the flotation process, the appropriate flotation agent is selected and the flotation conditions are adjusted according to the content and distribution of silicon dioxide; in the chemical purification process, the type and amount of chemical reagents are determined according to the type and content of impurities.

[0053] S12, after centrifugation, obtaining the proportion data of each component of the graphite after centrifugation and the shape data of the particles, wherein the shape data of the particles is the diameter data of the particles, which is stored in the second storage component; it should be noted that the preferred method for obtaining the diameter data of the particles here is: obtaining a picture of the particles, measuring the two points of the particles with the largest distance on the picture and setting them as the diameter data of the particles;

[0054] In this way, the proportion data of each component of the graphite raw material before graphite purification and the proportion data of each component of the graphite after centrifugation are obtained for comparison and calculation to obtain the decontamination effect. At the same time, the shape data of the particles is compared with the shape of the standard particles to obtain the particle size uniformity, and then the centrifugal effect is analyzed and judged;

[0055] S2. Obtaining the proportion data of each component of the graphite raw material and the proportion data of each component of the graphite after centrifugation, and importing them into the impurity removal effect evaluation model to evaluate the impurity removal effect;

[0056] In one specific embodiment, the specific steps of S2 are: Figure 2 As shown, S21, obtaining the proportion data of each component of the graphite raw material before graphite purification and the proportion data of each component of the graphite after centrifugation, substituting them into the component removal rate calculation formula to calculate the removal rate of each component, wherein the removal rate calculation formula of the i-th component is: Wherein, mi q is the proportion data of the i-th component of the graphite raw material before graphite purification, and mi h is the proportion data of the i-th component of the graphite raw material after graphite purification;

[0057] S22, substituting the obtained removal rates of each component and the proportion data of each component of the graphite raw material before graphite purification into the calculation formula of the abnormal value of the impurity removal effect to calculate the abnormal value of the impurity removal effect, wherein the calculation formula of the abnormal value of the impurity removal effect is: Wherein, a is the impurity removal ratio, n is the number of impurity components, z im is the minimum value of the standard safety range of the ith impurity removal rate, mkq is the total amount of graphite in the material after graphite purification, and mkh is the total amount of graphite in the material before graphite purification;

[0058] S23, obtaining the calculated abnormal value of the impurity removal effect and storing it;

[0059] In this way, the impurity removal effect of the centrifugal process is analyzed by the impurity removal effect and the amount of graphite removed;

[0060] S3, obtaining shape data of the particles and importing it into a particle size uniformity analysis model to perform particle size uniformity analysis;

[0061] In one specific embodiment, the specific steps of S3 are: Figure 3 As shown, S31, obtaining shape data of the centrifuged particles and shape data of the standard centrifuged particles;

[0062] S32, substituting the obtained shape data of the centrifuged particles and the shape data of the standard particles after centrifugation into the particle size uniformity abnormal value calculation formula to calculate the particle size uniformity abnormal value, wherein the particle size uniformity abnormal value calculation formula is: Wherein, exp() is the power of e, xj is the shape data of the jth particle, x is the shape data of the standard particle after centrifugation, and m is the number of particles;

[0063] S33, obtaining the calculated particle size uniformity abnormality value and storing it;

[0064] S4. Obtain the decontamination effect evaluation results and the particle size uniformity analysis results to perform centrifugal effect analysis;

[0065] In one specific embodiment, the specific content of S4 is: obtaining the calculated impurity removal effect abnormal value and particle size uniformity abnormal value, substituting the calculated impurity removal effect abnormal value and particle size uniformity abnormal value into the centrifugal effect analysis value calculation formula to calculate the centrifugal effect analysis value, wherein the centrifugal effect analysis value calculation formula is: Among them, g is the coefficient of the outlier ratio of the removal effect

[0066] S5. Provide equipment matching warning based on centrifugal effect analysis results;

[0067] In one specific embodiment, the specific content of S5 is: comparing the obtained centrifugal effect analysis value with the set centrifugal effect analysis threshold value. If the centrifugal effect analysis value is greater than or equal to the set centrifugal effect analysis threshold value, it means that the centrifugal process is qualified and the centrifugal equipment matches the graphite fiber purification process. If the centrifugal effect analysis value is less than the set centrifugal effect analysis threshold value, it means that the centrifugal process is unqualified and the centrifugal equipment does not match the graphite fiber purification process.

[0068] Centrifugal effect analysis is a method to evaluate the performance of the centrifugal process. It is usually used in industrial processes such as graphite purification. In the graphite purification process, centrifugal equipment is used to separate the solid and liquid components in the mixture to improve the purity of graphite. The quality of the centrifugal effect directly affects the efficiency and quality of graphite purification.

[0069] It is very important to set a reasonable centrifugal effect analysis threshold. When the centrifugal effect analysis value is greater than or equal to this threshold, it means that the centrifugal process is qualified and the centrifugal equipment can effectively complete the task of graphite purification. This usually indicates that the equipment is operating normally, the process parameters are set reasonably, and it can continue to be used.

[0070] On the contrary, if the centrifugal effect analysis value is lower than the set threshold, it indicates that the centrifugal process is unqualified, the separation efficiency of the equipment may not be high, and the graphite purification effect may not be ideal. At this time, it may be necessary to adjust or maintain the centrifugal equipment, optimize the process parameters, or check whether there are other factors affecting the effect of the centrifugal process, such as the nature of the material, equipment wear or setting errors;

[0071] In order to ensure the quality of the centrifugal process and the purity of the graphite products, it is necessary to regularly analyze the centrifugal effect and adjust and optimize the process conditions based on the results. This helps to improve production efficiency and product quality while avoiding the waste of resources and loss of production efficiency caused by unqualified centrifugal effects.

[0072] It should be noted that in this embodiment, the value-taking method of the impurity removal effect abnormal value proportion coefficient, the centrifugal effect analysis threshold and the impurity removal proportion coefficient is as follows: obtain the proportion data of each component of the graphite raw materials in at least 5000 groups of historical graphite purification processes, obtain the proportion data of each component of the graphite after centrifugation and the shape data of the particles, substitute the proportion data of each component of the graphite raw materials in the historical graphite purification process, the proportion data of each component of the graphite after centrifugation and the shape data of the particles into the centrifugal effect analysis value calculation formula to calculate the centrifugal effect analysis value, and at the same time obtain the qualified judgment results of the graphite purification corresponding to these data, substitute the calculated centrifugal effect analysis value and the qualified judgment result into the fitting software, and output the values ​​of the impurity removal effect abnormal value proportion coefficient, the centrifugal effect analysis threshold and the impurity removal proportion coefficient that meet the highest judgment accuracy.

[0073] It should be noted in this embodiment that the advantages of this embodiment over the prior art are: obtaining the proportion data of each component of the graphite raw material in the graphite purification process, obtaining the proportion data of each component of the graphite after centrifugation and the shape data of the particles, obtaining the proportion data of each component of the graphite raw material and the proportion data of each component of the graphite after centrifugation, and importing them into the de-impurity effect evaluation model to evaluate the de-impurity effect, obtaining the shape data of the particles and importing them into the particle size uniformity analysis model to analyze the particle size uniformity, obtaining the de-impurity effect evaluation results and the particle size uniformity analysis results to perform centrifugal effect analysis, performing equipment matching warning according to the centrifugal effect analysis results, obtaining the proportion data of each component of the graphite raw material before graphite purification and the proportion data of each component of the graphite after centrifugation, and comparing and calculating to obtain the de-impurity effect, and at the same time, comparing the shape data of the particles with the shape of the standard particles to obtain the particle size uniformity, and then analyzing and judging the centrifugal effect, thereby improving the judgment accuracy and judgment efficiency of the centrifugal effect analysis.
