[0076] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0077] Understandably, the existing automated production control of calcium carbonate powder production suffers from low technical level and low degree of automation. It requires manual control and intervention in process steps, which not only affects the production precision of calcium carbonate powder, resulting in the particle size distribution and particle morphology of the finished powder not meeting market demands, but also increases the cost of calcium carbonate powder production.

[0078] To address the aforementioned issues, this invention utilizes RFID technology for batch raw material identification and transportation, along with online quality monitoring to separate qualified and unqualified raw materials. Qualified raw materials are crushed and vibrated through screening according to preset crushing and grading parameters to obtain qualified calcium carbonate powder. The qualified calcium carbonate powder is then dried and mixed according to preset drying and modification parameters to obtain finished calcium carbonate powder. The product specifications of the finished calcium carbonate powder are obtained, and automatic packaging control is implemented, including checks on the integrity and accuracy of the packaging, before delivering qualified packaged calcium carbonate powder. Automatic warehousing and storage control is also implemented for the packaged calcium carbonate powder, along with receiving order logistics requests and scheduling outbound transportation based on those requests. This system enables automated batch raw material identification and transportation, crushing and vibrating screening, drying and mixing / modification, automatic packaging, warehousing and storage control, and outbound transportation scheduling. This significantly improves the level of automation in calcium carbonate powder production, enhancing both product quality and production costs.

[0079] Figure 1 A flowchart of the method provided by an embodiment of the present invention is shown.

[0080] Specifically, an automated production control method for calcium carbonate powder production includes the following steps:

[0081] Step S101: Based on RFID technology, identify and transport batch production raw materials, conduct online quality testing on batch production raw materials, and segment and divert qualified and unqualified production raw materials.

[0082] In this embodiment of the invention, the batch of raw materials is transferred to the pre-processing area by initial transfer control. Then, in the pre-processing area, the batch of raw materials is identified and registered based on RFID technology. The batch of raw materials is then subjected to online quality detection, and the online detection results are recorded. Based on the online detection results, a segmented diversion signal is generated. Based on the segmented diversion signal, qualified and unqualified raw materials are determined in segments, and then the qualified and unqualified raw materials are transported in a segmented diversion manner.

[0083] Specifically, Figure 2 The flowchart illustrates the segmented separation of qualified and unqualified production raw materials in the method provided by the embodiments of the present invention.

[0084] In a preferred embodiment of the present invention, the identification and transportation of batch production raw materials based on RFID technology, and the online quality detection of batch production raw materials, and the segmentation and diversion of qualified and unqualified production raw materials, specifically include the following steps:

[0085] Step S1011: Perform initial transfer control to transfer the batch of raw materials to the pretreatment area;

[0086] Step S1012: In the pre-processing area, the batch of raw materials is identified and the batch information is registered based on RFID technology.

[0087] Step S1013: Perform online quality testing on the batch of raw materials and record the online testing results;

[0088] Step S1014: Generate segmented split signals based on the online detection results;

[0089] In step S1014, the step of generating the segmented shunt signal based on the online detection result corresponds to the following function expression:

[0090]

[0091] Where S represents the generated segmented current-splitting signal, with a value between 0 and 1; Q represents the value of a specific detection index in the online detection result; R represents the pass threshold of the detection result; ε represents a positive coefficient used to control the sensitivity of the function at the pass threshold R; A represents the first adjustment parameter; B represents the second adjustment parameter; and n represents the third adjustment parameter.

[0092] As a supplementary explanation, the generated segmented flow signal S has a value between 0 and 1, with higher values ​​indicating a higher likelihood of the raw material being qualified, and lower values ​​indicating a possible failure of the raw material. The first adjustment parameter A controls the behavior of the function at low Q values. The second adjustment parameter B prevents division by zero and affects the shape of the function in the intermediate region. The third adjustment parameter n controls the degree of nonlinearity of the function.

[0093] Step S1015: Based on the segmented diversion signal, determine qualified and unqualified production raw materials, and perform segmented diversion for conveying qualified and unqualified production raw materials.

[0094] Furthermore, the automated production control method for calcium carbonate powder production also includes the following steps:

[0095] Step S102: According to the preset crushing and grading parameters, the qualified raw materials are crushed and vibrated and screened to obtain qualified calcium carbonate powder.

[0096] In this embodiment of the invention, according to preset crushing processing parameters, the rotation speed, feed rate, and crushing time are planned to generate crushing processing instructions. Then, according to the crushing processing instructions, the qualified raw materials are crushed and processed. After the crushing processing is completed, crushed calcium carbonate powder is obtained. Then, according to preset grading processing parameters, the particle size standard is planned to generate grading processing instructions. Then, according to the grading processing instructions, the crushed calcium carbonate powder is vibrated and screened. After the vibrating and screening is completed, qualified calcium carbonate powder is obtained, and unqualified calcium carbonate powder is crushed and reworked.

[0097] Specifically, Figure 3 A flowchart illustrating the method for obtaining qualified calcium carbonate powder provided in an embodiment of the present invention is shown.

[0098] In a preferred embodiment of the present invention, the production control of crushing and vibrating screening the qualified raw materials according to preset crushing and grading parameters to obtain qualified calcium carbonate powder specifically includes the following steps:

[0099] Step S1021: According to the preset crushing processing parameters, the rotation speed, feed rate and crushing time are planned, and a crushing processing instruction is generated;

[0100] Step S1022: According to the crushing and processing instruction, the qualified production raw materials are crushed and processed to obtain crushed calcium carbonate powder;

[0101] Step S1023: According to the preset grading processing parameters, the particle size standard is planned and a grading processing instruction is generated.

[0102] In step S1023, the step of planning particle size standards and generating grading processing instructions according to preset grading processing parameters is used to determine the strictness of screening and the proportion of rework by calculating the intensity index of the grading processing instructions.

[0103] The functional expression for calculating the intensity index of graded processing instructions is as follows:

[0104]

[0105] Among them, I gc D represents the intensity index of graded processing instructions. 50，target D represents the median particle size of the target product. 50，initial η represents the initial median particle size of the raw material. screen D represents the screening efficiency of the vibrating screen. 90,target D represents the particle size value at the 90% passing point of the target particle size distribution. 10，target S represents the particle size value at the 10% passing point of the target particle size distribution. target S represents the standard value of the specific surface area of ​​the target product.max α represents the theoretical maximum value of the specific surface area, and α, β, γ and δ all represent the first empirical parameters.

[0106] It should be noted that the formula for the intensity index of the grading processing instruction takes into account the ratio of the target particle size to the raw material particle size, screening efficiency, the width of the target particle size distribution, and the specific surface area specification. Using this formula, an intensity index I for the grading processing instruction can be generated. gc This index can be used to determine the stringency of screening and the rework rate of defective products. Finally, according to I... gc The value of I can be used to set different screening and rework strategies. For example, when I gc When the threshold is exceeded, the screening process can be made more rigorous or the rework rate can be increased to ensure product quality.

[0107] Step S1024: According to the grading processing instruction, the pulverized calcium carbonate powder is subjected to vibration sieving to obtain qualified calcium carbonate powder, and the unqualified calcium carbonate powder is subjected to pulverization and rework control.

[0108] Furthermore, the automated production control method for calcium carbonate powder production also includes the following steps:

[0109] Step S103: According to the preset drying and modification parameters, the qualified calcium carbonate powder is dried and mixed for production control to obtain the product calcium carbonate powder.

[0110] In this embodiment of the invention, a drying processing instruction is generated according to preset drying processing parameters. Then, the drying time and temperature curve are automatically adjusted based on the preset material moisture content. The qualified calcium carbonate powder is dried and processed according to the drying processing instruction. After the drying process is completed, the dried calcium carbonate powder is obtained. Then, according to the preset modification formula parameters, the automatic batching control is performed to obtain the modifier. The modifier is mixed with the dried calcium carbonate powder and controlled. During the mixing process, the modification temperature, pressure and reaction time are controlled to obtain the product calcium carbonate powder.

[0111] Specifically, Figure 4 A flowchart illustrating the method for obtaining calcium carbonate powder provided in an embodiment of the present invention is shown.

[0112] In a preferred embodiment of the present invention, the production control of drying and mixing the qualified calcium carbonate powder according to preset drying and modification parameters to obtain the product calcium carbonate powder specifically includes the following steps:

[0113] Step S1031: Generate a drying processing instruction according to the preset drying processing parameters;

[0114] Step S1032: Based on the preset material moisture content, the drying time and temperature curve are automatically adjusted, and the qualified calcium carbonate powder is dried according to the drying processing instructions to obtain dried calcium carbonate powder.

[0115] In step S1032, the step of automatically adjusting the drying time and temperature curve based on the preset material moisture content and drying the qualified calcium carbonate powder according to the drying processing instruction includes at least the drying time and the drying temperature at each moment. The function expression corresponding to the drying temperature is:

[0116]

[0117] Where T(t) represents the drying temperature at time t, T base T represents the temperature at the start of the drying process. max This represents the highest temperature that can be reached during the drying process, t represents the current time, t0 represents the point at which the temperature begins to rise, k1 and k2 are both primary parameters controlling the shape of the temperature curve, and MC init MC represents the initial moisture content of the material. target This represents the expected moisture content during the drying process; the function expression for the drying time is:

[0118]

[0119] Among them, t dry This represents the estimated drying time calculated based on the initial and target moisture content of the material; k3 represents the parameter controlling the drying rate; MC... final This represents the final moisture content after drying. As a supplementary explanation, the function expression for drying temperature shows an initial lower temperature that gradually increases over time; the rate of temperature increase depends on the values ​​of k1 and k2, as well as the difference between the initial and target moisture contents of the material. Furthermore, the function expression for drying time is used to estimate the total drying time required for the entire process; this drying time is related to the initial, target, and final moisture contents of the material.

[0120] Step S1033: Automatic batching control is performed according to the preset modified formula parameters to obtain the modifier.

[0121] Step S1034: The modifier and the dried calcium carbonate powder are mixed and controlled.

[0122] Step S1035 involves controlling the modification temperature, pressure, and reaction time to obtain the product calcium carbonate powder.

After the automatic packaging is completed, the integrity and accuracy of the packaging are compared and tested according to the preset packaging appearance model, qualified packaged calcium carbonate powder is selected, and the qualified packaged calcium carbonate powder is transported.
