Description

Technical Field

[0001] The present invention relates to the technical field of phosphogypsum modification, and in particular to a phosphogypsum modification method and device. Background Art

[0002] Phosphogypsum is a major byproduct of wet-process phosphoric acid production. However, it often contains a certain amount of harmful impurities, such as fluoride, unreacted phosphate, and other organic matter. These impurities not only affect the physical and chemical properties of phosphogypsum but also pose potential hazards to the environment and human health. Therefore, modification of phosphogypsum is particularly necessary.

[0003] In phosphogypsum dumps, the varying storage time and aging of phosphogypsum waste in different regions, coupled with differences in production processes and phosphate rock quality, lead to significant variations in phosphogypsum contaminant content, pH value, moisture content, and other factors across plots and depths within the same site. These factors severely impact the effectiveness and efficiency of phosphogypsum modification processes.

[0004] Currently, a uniform and relatively large process parameter is usually used to treat the entire phosphogypsum in the storage yard to achieve phosphogypsum modification. However, the above method has the following problems:

[0005] 1. Extension of construction period: Using uniform and large process parameters, especially for phosphogypsum with less demanding processing conditions, will result in excessively long processing time and affect the overall construction progress.

[0006] 2. Increased energy consumption: The higher operating power, longer reaction time and larger dosage set to ensure the modification effect increase electricity consumption and other energy consumption.

[0007] 3. Waste of reagents: High-intensity treatment is still applied to phosphogypsum with low pollutant content or naturally aged, resulting in a large amount of waste of modification reagents and increasing operating costs.

[0008] 4. Low economic benefits: The above problems have caused the cost of phosphogypsum modification to increase significantly, reducing its economic value as a resource reuse. Summary of the Invention

[0009] In view of this, the present invention provides a method and apparatus for modifying phosphogypsum to solve the problem that the existing phosphogypsum modification method only uses uniform and relatively large process parameters, resulting in low modification efficiency and high modification cost.

[0010] In a first aspect, the present invention provides a phosphogypsum modification method, which is applied to a phosphogypsum modification device, wherein the phosphogypsum modification device has self-propelled capability;

[0011] The method includes:

[0012] For each plot in the target area, obtain the raw material characteristics of the phosphogypsum in the plot at each preset depth;

[0013] Based on the raw material characteristics of the phosphogypsum at each preset depth of the plot, determine the equipment operating parameter curve corresponding to the plot;

[0014] Based on the attribute information of the target area, the attribute information of the phosphogypsum modification system, and the equipment operating parameter curve corresponding to each plot, determine the operation plan and reference operation cost of the phosphogypsum modification system;

[0015] According to the operation plan, determine the target plot and target preset depth;

[0016] Based on the equipment operating parameter curve corresponding to the target plot, the phosphogypsum at the target preset depth is modified. After the modification is completed, the actual operating cost is obtained to determine whether the actual operating cost is greater than the reference operating cost;

[0017] When the actual operating cost is greater than the reference operating cost, based on the current position of the phosphogypsum modification system, return to the attribute information of the target area, the attribute information of the phosphogypsum modification system and the equipment operating parameter curve corresponding to each plot, and determine the operation plan of the phosphogypsum modification system and its reference operating cost steps until the modification work of the phosphogypsum in the target area is completed.

[0018] The phosphogypsum modification method provided by the embodiment of the present invention obtains the raw material characteristics of phosphogypsum at multiple preset depths for each plot in the target area, so as to accurately understand the specific conditions of phosphogypsum at different depths, provide a scientific basis for subsequent modification, and determine the corresponding equipment operating parameters according to the raw material characteristics of phosphogypsum at different depths, so that reasonable equipment operating parameters can be adopted in the modification process, energy consumption can be reduced, and costs can be saved. The operation plan of the equipment in the modification operation is then determined, so that the modification work can be carried out according to the operation plan. After the modification of the phosphogypsum at the target preset depth is completed, it is determined whether the actual operation cost is greater than the reference operation cost, ensuring that each modification operation is within the budget. Through precise evaluation, optimized operation and efficient planning, the modification effect is significantly improved, the overall efficiency of the phosphogypsum modification operation is improved, and the waste of time and resources is reduced. At the same time, from the optimization of equipment operating parameters to the operation plan, and then to cost control, the cost of the modification operation is reduced and the economic benefits are improved.

[0019] In an optional embodiment, after determining whether the actual operating cost is greater than the reference operating cost, the method further includes:

[0020] When the actual operating cost is not greater than the reference operating cost, the modification work will continue based on the operating plan.

[0021] The phosphogypsum modification method provided in an embodiment of the present invention improves the overall efficiency of the phosphogypsum modification operation and reduces time and resource waste by continuing to perform the modification operation according to the operation plan when the actual operation cost is not greater than the reference operation cost.

[0022] In an optional embodiment, before determining the equipment operating parameter curve corresponding to the plot based on the raw material characteristics of the phosphogypsum in the plot at each preset depth, the method further includes:

[0026] The phosphogypsum modification method provided in an embodiment of the present invention simulates the modification process of phosphogypsum with each raw material characteristic to obtain simulated operating parameters corresponding to the raw material characteristics. At the same time, combined with the actual operating parameters obtained in actual experiments, the optimal operating parameters of the modification equipment when modifying the phosphogypsum with each raw material characteristic are determined, ensuring that the equipment operating parameters are closer to the actual application scenario and improving the modification effect.

[0027] In an optional embodiment, based on the raw material characteristics of the phosphogypsum of the plot at each preset depth, determining the equipment operating parameter curve corresponding to the plot includes:

[0028] Based on the raw material characteristics of phosphogypsum at each preset depth of the plot, equipment operating parameters corresponding to the raw material characteristics are obtained;

[0029] Based on the equipment operating parameters corresponding to the raw material characteristics of phosphogypsum at each preset depth of the plot, an equipment operating parameter curve corresponding to the plot is generated according to the depth order of the multiple preset depths of the plot.

[0030] The phosphogypsum modification method provided in an embodiment of the present invention forms an equipment operating parameter curve corresponding to a plot of land based on the equipment operating parameters corresponding to the raw material characteristics of the phosphogypsum at each preset depth of the plot of land, so that the curve can reflect the equipment operating parameters of a plot of land when modified with different raw material characteristics, thereby providing support for the modification process.

[0031] In an optional embodiment, based on the attribute information of the target area, the attribute information of the phosphogypsum modification system, and the equipment operation parameter curve corresponding to each plot, an operation plan and a reference operation cost of the phosphogypsum modification system are determined, including:

[0032] Determine the target layout plan and its operating cost based on the attribute information of the target area, the attribute information of the phosphogypsum modification system, and the equipment operating parameter curve corresponding to each plot;

[0033] Based on the target layout plan, multiple candidate movement routes are generated;

[0034] Determine a target moving route and its transportation cost based on multiple candidate moving routes;

[0035] The target layout plan and the target movement route are used as the operation plan, and the sum of the operation cost of the target layout plan and the transportation cost of the target movement route is used as the reference operation cost.

[0036] The phosphogypsum modification method provided in an embodiment of the present invention determines a target layout plan by considering multiple factors, and thereby determines multiple candidate movement routes, from which the target movement route is determined, thereby forming an operation plan, so that the modification cost is reduced when the modification operation is performed according to the operation plan.

[0037] In an optional embodiment, the attribute information of the target area includes a three-dimensional model and stratum depth information;

[0038] Based on the attribute information of the target area, the attribute information of the phosphogypsum modification system, and the equipment operating parameter curve corresponding to each plot, the target layout plan and its operating cost are determined, including:

[0042] The candidate layout plan corresponding to the minimum operation cost is determined as the target layout plan.

[0043] The phosphogypsum modification method provided in the embodiment of the present invention ensures that the target layout scheme finally selected is the optimal solution by generating multiple candidate layout schemes and performing simulated modification, thereby improving the efficiency of the modification operation and reducing the modification cost.

[0044] In an optional embodiment, determining a target movement route and its transportation cost based on multiple candidate movement routes includes:

[0046] The candidate movement route corresponding to the minimum transportation cost is determined as the target movement route.

[0047] The phosphogypsum modification method provided in an embodiment of the present invention simulates the movement process of the phosphogypsum modification equipment in all plots according to each candidate movement route, calculates the transportation cost, and selects the route with the lowest transportation cost as the final target movement route, thereby minimizing the time and energy consumption during the system and material movement and operation process, and reducing the modification operation cost.

[0048] In an optional embodiment, the phosphogypsum modification equipment includes a vibrator, a crusher, an automatic dosing machine, and a mixer;

[0049] Based on the equipment operating parameter curve corresponding to the target plot, the phosphogypsum at the target preset depth is modified, including:

[0050] Based on the conveying equipment, transport the phosphogypsum to the preset depth;

[0051] Based on the raw material characteristics of phosphogypsum at the target preset depth, the corresponding equipment operating parameters are determined from the equipment operating parameter curve corresponding to the target plot;

[0052] Adjust the parameters of the vibrator, crusher, automatic dosing machine and mixer based on the equipment operating parameters corresponding to the target preset depth;

[0053] The phosphogypsum modification equipment modifies the phosphogypsum at a target preset depth based on the adjusted parameters.

[0054] The phosphogypsum modification method provided in an embodiment of the present invention uses a conveying device to transport phosphogypsum of a target preset depth, and adjusts the parameters of a vibrator, a crusher, an automatic dosing machine, and a mixer in the equipment according to the corresponding equipment operating parameters in the equipment operating parameter curve, so that the phosphogypsum of the target preset depth is modified using the phosphogypsum modification equipment after the adjustment. By precisely adjusting the operating parameters of the equipment, it is ensured that the phosphogypsum of each preset depth can be modified under optimal conditions, thereby improving the modification quality, ensuring the maximum utilization of resources, and reducing the waste of energy, chemicals, and time.

[0055] In an optional embodiment, the phosphogypsum at a target preset depth is modified based on the phosphogypsum modification device after adjusting parameters, including:

[0056] Vibrating the phosphogypsum at a target preset depth using a vibration machine;

[0077] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0078] Existing phosphogypsum modification methods use only uniform, relatively large process parameters, resulting in low modification efficiency and high modification costs. The phosphogypsum modification method provided by the embodiments of the present invention significantly improves the modification effect through precise assessment, optimized operation, and efficient planning, increasing the overall efficiency of the phosphogypsum modification operation and reducing time and resource waste. Furthermore, from optimizing equipment operating parameters to movement routes and then to cost control, the modification operation costs are reduced and economic benefits are improved.

[0079] According to an embodiment of the present invention, an embodiment of a method for modifying phosphogypsum is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0080] In this embodiment, a phosphogypsum modification method is provided, which can be used in a phosphogypsum modification system, including a phosphogypsum modification device and a conveying device. The phosphogypsum modification device has self-propelled capability. Figure 1 Flowchart of the method for modifying phosphogypsum according to an embodiment of the present invention is as follows: Figure 1 As shown, the process includes the following steps:

[0081] Step S101: For each plot in the target area, obtain the raw material characteristics of the phosphogypsum in the plot at each preset depth.

[0082] Specifically, a plot is a unit of land with defined boundaries and area, and the target area includes multiple plots. Using geological drilling equipment, phosphogypsum samples are collected at each preset depth (e.g., from 0 to 13 meters underground, with each meter representing a preset depth). Chemical analysis is performed on the collected phosphogypsum samples to determine their contaminant content, pH value, moisture content, and other information. This data, as raw material characteristics of the phosphogypsum, can be used to understand the specific composition and contamination level of the phosphogypsum, providing a scientific basis for subsequent modification and treatment.

[0083] Step S102: determining an equipment operation parameter curve corresponding to the plot based on the raw material characteristics of the phosphogypsum in the plot at each preset depth.

[0084] Specifically, because the prior art uses uniform parameters when modifying phosphogypsum, it leads to problems of low modification efficiency and high modification cost. Therefore, the embodiment of the present invention determines the corresponding equipment operating parameters, such as the type of reagent, dosage, vibration frequency, crusher speed, mixing time and other parameters, for each preset depth of phosphogypsum in each plot based on its raw material characteristics, thereby forming an equipment operating parameter curve for each plot. When modifying phosphogypsum on each plot, the corresponding equipment operating parameters are determined from the equipment operating parameter curve based on the raw material characteristics of the phosphogypsum at each preset depth, and the phosphogypsum modification equipment is set accordingly before performing the phosphogypsum modification operation, which can effectively improve the modification efficiency and effect while reducing the modification cost.

[0085] Step S103: determining an operation plan and a reference operation cost of the phosphogypsum modification system based on the attribute information of the target area, the attribute information of the phosphogypsum modification system, and the equipment operation parameter curve corresponding to each plot.

[0086] Specifically, the process of phosphogypsum modification involves a large amount of excavation and transportation work. Therefore, the cost incurred during the purchase, rental, and use of excavation and transportation equipment such as excavators, loaders, and trucks is one of the largest costs. If the phosphogypsum modification equipment cannot be moved, a large amount of related equipment will be required to excavate the phosphogypsum and transport it to the equipment, resulting in high usage costs. In addition, excavation work will inevitably affect the terrain. As the land around the equipment is modified and cleared, the ground lowers, which makes transportation difficult and increases transportation costs. If the equipment is transferred to another plot of land by truck and crane at this time, the transfer will take a long time, and installation and debugging will be required after the transfer. The above-mentioned factors extend the construction period and increase the operating costs. The embodiment of the present invention uses phosphogypsum modification equipment with self-propelled ability, which can be flexibly moved to the plot of land that needs to be modified without the use of other transportation equipment, and is combined with the conveying equipment into a system. By determining the system's operating plan and performing the modification work based on it, the modification operation cost and construction time are reduced, while the modification operation efficiency is improved.

[0087] Step S104: determining the target plot and the target preset depth according to the operation plan.

[0088] Specifically, the operation plan includes the system's location and movement route, from which a target plot can be determined. The system will use this target plot as the modification starting point and perform modification work in the target area. Because each plot has multiple preset depths, a target preset depth must also be determined.

[0089] Step S105 , based on the equipment operating parameter curve corresponding to the target plot, modify the phosphogypsum located at the target preset depth. After the modification is completed, obtain the actual operating cost and determine whether the actual operating cost is greater than the reference operating cost.

[0090] Specifically, based on the equipment operating parameter curve corresponding to the target plot, the phosphogypsum modification equipment is controlled to modify the phosphogypsum at the target preset depth. After completing the modification of the phosphogypsum at the target preset depth, the actual operating cost is calculated. Comparing the actual operating cost with the reference operating cost of the operation plan helps to promptly identify any cost overruns during the modification process and facilitate cost control.

[0091] Step S106, when the actual operating cost is greater than the reference operating cost, based on the current position of the phosphogypsum modification system, return to the step of determining the operating plan of the phosphogypsum modification system and its reference operating cost based on the attribute information of the target area, the attribute information of the phosphogypsum modification system, and the equipment operating parameter curve corresponding to each plot, until the modification work of the phosphogypsum in the target area is completed.

[0092] Specifically, when the actual operating cost exceeds the reference operating cost, the system returns to step S103 based on the current location of the phosphogypsum modification system and redefines the operating plan and its reference operating cost until all phosphogypsum in the target area has been modified. By continuously adjusting the operating plan, the system ensures timely optimization based on actual conditions during the modification process, ensuring that the entire modification process is carried out with the lowest cost and highest efficiency.

[0093] The phosphogypsum modification method provided by the embodiment of the present invention obtains the raw material characteristics of phosphogypsum at multiple preset depths for each plot in the target area, so as to accurately understand the specific conditions of phosphogypsum at different depths, provide a scientific basis for subsequent modification, and determine the corresponding equipment operating parameters according to the raw material characteristics of phosphogypsum at different depths, so that reasonable equipment operating parameters can be adopted in the modification process, energy consumption can be reduced, and costs can be saved. The operation plan of the equipment in the modification operation is then determined, so that the modification work can be carried out according to the operation plan. After the modification of the phosphogypsum at the target preset depth is completed, it is determined whether the actual operation cost is greater than the reference operation cost, ensuring that each modification operation is within the budget. Through precise evaluation, optimized operation and efficient planning, the modification effect is significantly improved, the overall efficiency of the phosphogypsum modification operation is improved, and the waste of time and resources is reduced. At the same time, from the optimization of equipment operating parameters to the operation plan, and then to cost control, the cost of the modification operation is reduced and the economic benefits are improved.

[0094] In this embodiment, a method for modifying phosphogypsum is provided, which can be used in the above-mentioned phosphogypsum modification system. The method specifically includes the following steps:

[0095] Step S201: For each plot in the target area, obtain the raw material characteristics of phosphogypsum at each preset depth. Figure 1 Step S101 of the illustrated embodiment will not be described in detail here.

[0096] Step S202 simulates the modification process of the phosphogypsum with these raw material properties based on the raw material properties of the target area, and determines the simulated operating parameters corresponding to the phosphogypsum with these raw material properties. Specifically, the simulation is performed using professional engineering simulation software or a custom algorithm, using the raw material properties of the phosphogypsum as input. The equipment operating parameters are adjusted to simulate the modification process, and the impact on the modification effect is observed. The equipment operating parameters that correspond to the best modification effect are used as the simulated operating parameters. This simulated modification process provides theoretical equipment operating parameters, providing a reference for determining equipment operating parameters while saving time and resources.

[0097] Step S203 obtains the actual operating parameters corresponding to the raw material characteristics of the phosphogypsum. The actual operating parameters represent the parameters obtained by conducting a modification experiment on the raw material characteristics of the phosphogypsum under actual pilot conditions. Specifically, the actual operating parameters are obtained by staff conducting a small-scale test on a sample of phosphogypsum with the raw material characteristics under laboratory conditions. More specifically, the staff simulates the actual modification process, observes the modification effect by continuously changing the equipment operating parameters, and uses the equipment operating parameters corresponding to the best modification effect as the actual operating parameters. Through actual small-scale experiments, a reference basis is provided for determining the equipment operating parameters, while saving time and resources.

[0098] Step S204 determines the equipment operating parameters corresponding to the phosphogypsum material characteristics based on the simulated operating parameters and the actual operating parameters. Specifically, weights can be assigned to the simulated operating parameters and the actual operating parameters, with larger weights indicating a greater impact on the final equipment operating parameters. Taking a weighted average of the two operating parameters and their corresponding weights allows for a more accurate determination of the final equipment operating parameters corresponding to the material characteristics.

[0099] Step S205 : determining an equipment operation parameter curve corresponding to the plot based on the raw material characteristics of the phosphogypsum in the plot at each preset depth.

[0100] Specifically, the above step S205 includes:

[0101] Step S2051: Based on the raw material properties of the phosphogypsum at each preset depth in the plot, equipment operating parameters corresponding to the raw material properties are obtained. Specifically, the raw material properties of the phosphogypsum at each preset depth vary, and corresponding equipment operating parameters are obtained based on the raw material properties of the phosphogypsum at different depths.

[0102] Step S2052, based on the equipment operating parameters corresponding to the raw material characteristics of the phosphogypsum at each preset depth of the plot, generates an equipment operating parameter curve corresponding to the plot in the depth order of the multiple preset depths of the plot. Specifically, the equipment operating parameters obtained according to the raw material characteristics of the phosphogypsum at different preset depths can be used to draw the equipment operating parameter curve corresponding to the plot. The horizontal coordinate of the equipment operating parameter curve of any plot is the raw material characteristics of the phosphogypsum, and the vertical coordinate is the equipment operating parameter. By generating the equipment operating parameter curve, before modifying the phosphogypsum at any preset depth of any plot, the corresponding equipment operating parameters are obtained according to the raw material characteristics of the phosphogypsum at the preset depth according to the curve, so as to achieve efficient modification.

[0103] Step S206 , based on the attribute information of the target area, the attribute information of the phosphogypsum modification system, and the equipment operation parameter curve corresponding to each plot, an operation plan of the phosphogypsum modification system and a reference operation cost thereof are determined.

[0104] Specifically, the above step S206 includes:

[0105] Step S2061: Determine the target layout plan and its operating cost based on the attribute information of the target area, the attribute information of the phosphogypsum modification system, and the equipment operation parameter curve corresponding to each plot. The attribute information of the target area includes a three-dimensional model and stratum depth information.

[0106] In some optional implementations, the above step S2061 includes:

[0107] Step a1: Based on the 3D model of the target area and the stratigraphic depth information, the volume of phosphogypsum at each preset depth for each plot in the target area is determined. Specifically, a laser point cloud image generated by 3D mapping of the target area using LiDAR is imported into modeling software to construct a 3D model of the target area. Combined with the stratigraphic depth information, the volume of phosphogypsum at each preset depth for each plot in the target area can be accurately determined.

[0108] Step a2 generates multiple candidate layout plans based on the 3D model of the target area, the volume of phosphogypsum on each plot, the properties of the phosphogypsum modification system, and the corresponding equipment operating parameter curves for each plot. Specifically, the 3D model of the target area provides an intuitive understanding of the topography, terrain relief, and spatial dimensions. Based on these characteristics, the system's placement is considered, avoiding locations with complex terrain that are unfavorable for operation or material transportation, such as low-lying, waterlogged areas or steeply sloped areas. If the site has significant elevation differences, the system can be planned for relatively flat areas. If areas lack sufficient support, avoid deploying the system there. Furthermore, for larger plots, deploying the system near areas with significant phosphogypsum reserves can reduce material transportation distances and costs. Furthermore, the corresponding equipment operating parameter curves for each plot reflect the specific equipment operating requirements for phosphogypsum treatment at each plot. These curves can be used to optimize equipment layout details. For example, the system should be deployed in a location with sufficient power supply and good equipment stability to ensure stable operation and meet treatment requirements. Furthermore, the properties of the phosphogypsum modification system, such as the equipment model, processing capacity, and dimensions, also influence the layout. By comprehensively considering these factors and considering various perspectives and conditions, we developed multiple candidate layout options. These options encompass different equipment placement options within the site to meet varying processing requirements and site conditions.

[0109] In step a3, for each candidate layout, based on the equipment operating parameter curve corresponding to each plot, the operating cost for simulated modification at each preset depth of each plot in the candidate layout is determined. This operating cost includes both movement cost and modification cost. Specifically, for each candidate layout, the modification of phosphogypsum at each preset depth of each plot is simulated according to the equipment operating parameter curve corresponding to each plot. During the simulation, the operating cost is calculated, including movement cost (time required to move the system and materials, fuel consumption, equipment wear and tear, etc.) and modification cost (cost of chemicals required to process phosphogypsum, electricity cost for system operation, etc.). Through precise simulation and calculation, a clear understanding of the actual cost consumption of each candidate layout can be obtained.

[0110] Step a4 determines the candidate layout scheme with the lowest operating cost as the target layout scheme. Specifically, the operating costs of each candidate layout scheme are compared, and the candidate scheme with the lowest operating cost is selected as the target layout scheme. This selection ensures that costs are minimized and economic benefits are maximized while still meeting the requirements for phosphogypsum modification.

[0111] Step S2062: Generate multiple candidate movement routes based on the target deployment plan. Specifically, after determining the target deployment plan, use any path planning algorithm based on the deployment location of the system to plan multiple candidate routes for the system to move between all plots.

[0112] Step S2063: Determine a target moving route and its transportation cost based on the multiple candidate moving routes.

[0113] In some optional implementations, the above step S2063 includes:

[0114] Step b1: For each candidate route, simulate the movement of the phosphogypsum modification system across all plots of land based on the candidate route to determine the transportation cost of the candidate route. Specifically, for each candidate route, calculate the transportation cost by simulating the movement of the phosphogypsum modification system across all plots of land along that route. This transportation cost includes fuel consumption, wear and tear during system and material movement, and transportation and commissioning time.

[0115] Step b2: Determine the candidate movement route corresponding to the minimum transportation cost as the target movement route. Specifically, compare the transportation costs of all candidate movement routes and select the candidate route with the minimum transportation cost as the target movement route to reduce the overall modification cost.

[0116] In step S2064, the target layout plan and target movement route are used as the operation plan, and the sum of the operation cost of the target layout plan and the transportation cost of the target movement route is used as the reference operation cost. Specifically, the determined target layout plan and target movement route are combined to form an operation plan for the phosphogypsum modification system. Simultaneously, the operation cost of the target layout plan and the transportation cost of the target movement route are added together to form the reference operation cost for the operation plan. By determining the operation plan and its cost, performing modification operations according to the operation plan can improve modification efficiency and reduce modification costs.

[0117] Step S207: Determine the target plot and target preset depth according to the operation plan. Figure 1 Step S104 of the illustrated embodiment will not be described in detail here.

[0118] Step S208: Based on the equipment operating parameter curve corresponding to the target plot, the phosphogypsum located at the target preset depth is modified. After the modification is completed, the actual operating cost is obtained to determine whether the actual operating cost is greater than the reference operating cost. The phosphogypsum modification equipment includes a vibrator, a crusher, an automatic dosing machine and a mixer.

[0119] Specifically, step S208 modifies the phosphogypsum at the target preset depth based on the equipment operation parameter curve corresponding to the target plot, including:

[0120] Step S2081: transporting phosphogypsum to a target preset depth using a conveying device. Specifically, the phosphogypsum to a target preset depth is obtained by the conveying device so that the phosphogypsum modification device modifies the phosphogypsum.

[0121] Step S2082 determines corresponding equipment operating parameters from the equipment operating parameter curve corresponding to the target plot based on the raw material properties of the phosphogypsum at the target preset depth. Specifically, because the equipment operating parameter curve for each plot includes equipment operating parameters corresponding to the raw material properties of each type of phosphogypsum in that plot, before modifying the phosphogypsum at the target preset depth, the system first obtains the corresponding equipment operating parameters based on the raw material properties of the phosphogypsum at the target preset depth using this curve.

[0122] Step S2083: Based on the equipment operating parameters corresponding to the target preset depth, the parameters of the vibrator, crusher, automatic dosing machine, and mixer are adjusted. Specifically, the parameters of the different machines in the equipment are adjusted according to the equipment operating parameters to achieve efficient modification operations.

[0123] Step S2084: Modify the phosphogypsum at the target preset depth based on the phosphogypsum modification equipment with adjusted parameters.

[0124] In some optional implementations, the above step S2084 includes:

[0125] Step c1: Vibrate the phosphogypsum at a target preset depth using a vibrator. Specifically, steps c1 to c5 represent the actual workflow of the phosphogypsum modification equipment. First, the vibrator vibrates the phosphogypsum at a target preset depth using an adjusted vibration frequency. This effectively loosens the accumulated phosphogypsum, making it more porous and ensuring a uniform distribution of the phosphogypsum, avoiding clumping and unevenness.

[0126] Step c2 is to crush the vibrated phosphogypsum using a crusher. Specifically, the crusher, based on the adjusted crusher speed, crushes the phosphogypsum into smaller particles, increasing its specific surface area, thereby increasing the contact area between the reagent and the phosphogypsum and enhancing the modification effect.

[0127] Step c3: adding a reagent to the crushed phosphogypsum using an automatic dosing machine. Specifically, the automatic dosing machine evenly adds the reagent to the phosphogypsum based on the type and amount of the reagent, thereby improving the modification efficiency and quality of the phosphogypsum.

[0128] Step c4: Using a mixer, the phosphogypsum, after the reagent has been added, is subjected to primary and secondary mixing. Specifically, the mixer is initially subjected to primary mixing at a relatively low speed for a predetermined period of time, based on the adjusted mixing time and mixing intensity, to achieve a preliminary uniform distribution of the reagent and the phosphogypsum, ensuring no significant stratification or agglomeration. Subsequently, based on this initial mixing, the stirring speed is increased for a predetermined period of secondary mixing to ensure sufficient contact between the reagent and the phosphogypsum.

[0129] Step c5: Outputting the mixed phosphogypsum via a conveying device. Specifically, the phosphogypsum is modified through the above steps, and the modified phosphogypsum is transported to a designated location via a conveying device.

[0130] Step S209: If the actual operating cost is greater than the reference operating cost, based on the current location of the phosphogypsum modification system, return to the step of determining the operating plan of the phosphogypsum modification system and its reference operating cost based on the attribute information of the target area, the attribute information of the phosphogypsum modification system, and the equipment operating parameter curve corresponding to each plot, until the modification of the phosphogypsum in the target area is completed. Figure 1 Step S106 of the illustrated embodiment will not be described in detail here.

[0131] Step S210: If the actual operating cost is not greater than the reference operating cost, the modification process is continued based on the operation plan. Specifically, by continuing the modification process according to the operation plan when the actual operating cost is not greater than the reference operating cost, the overall efficiency of the phosphogypsum modification operation is improved, and time and resource waste is reduced.

[0132] In some optional embodiments, Figure 2 is a flow chart of another phosphogypsum modification method according to an embodiment of the present invention, such as Figure 2As shown, two pre-processing operations are performed before the actual modification operation. First, by determining the system's target layout and target movement route, the system's operation plan and reference operating cost are determined. Second, based on the raw material characteristics of the phosphogypsum at each preset depth in each plot, an equipment operating parameter curve corresponding to each plot is generated. During the actual modification operation, the system modifies the phosphogypsum at the target preset depth in the target plot according to the operation plan. The phosphogypsum is transported to the phosphogypsum modification equipment via conveying equipment, and the machine parameters in the equipment are adjusted to the equipment operating parameters corresponding to the raw material characteristics of the phosphogypsum at the target preset depth. Modification is then performed using a vibrator, crusher, automatic dosing machine, and mixer, and the modified phosphogypsum is discharged via conveying equipment. The actual operating cost of the current modification is then obtained and determined to be within the reference operating cost. If it is, the modification continues according to the operation plan. If it is, the operation plan and reference operating cost are re-determined, starting from the current system location. The modification operation terminates when all plots in the target area have been modified.

[0133] The phosphogypsum modification method provided by the embodiment of the present invention obtains the raw material characteristics of phosphogypsum at multiple preset depths for each plot in the target area, so as to accurately understand the specific conditions of phosphogypsum at different depths, provide a scientific basis for subsequent modification, and determine the corresponding equipment operating parameters according to the raw material characteristics of phosphogypsum at different depths, so that reasonable equipment operating parameters can be adopted in the modification process, energy consumption can be reduced, and costs can be saved. The operation plan of the equipment in the modification operation is then determined, so that the modification work can be carried out according to the operation plan. After the modification of the phosphogypsum at the target preset depth is completed, it is determined whether the actual operation cost is greater than the reference operation cost, ensuring that each modification operation is within the budget. Through precise evaluation, optimized operation and efficient planning, the modification effect is significantly improved, the overall efficiency of the phosphogypsum modification operation is improved, and the waste of time and resources is reduced. At the same time, from the optimization of equipment operating parameters to the operation plan, and then to cost control, the cost of the modification operation is reduced and the economic benefits are improved.
