Description

Technical Field

[0001] The present application relates to the technical field of iron and steel metallurgy, and in particular to a production control method, device, equipment and storage medium for mixed ore for sintering. Background Art

[0002] Sintering is a critical step in steel production, where fine iron ore, lime, and coal are mixed and calcined into clinker. The resulting sintered ore directly determines the blast furnace's utilization factor, coke ratio, and permeability. As production capacity expands, the batching workshop must simultaneously store and precisely proportion a variety of bulk materials, including mixed ore, cold return ore, fuel, and flux. This places higher demands on space, equipment, energy consumption, and personnel scheduling.

[0003] The industry currently generally adopts a "secondary stockyard + primary mixing" process: (1) Receiving trough → silo → secondary stockyard (where the stacker-reclaimer scrapes and mixes the ore) → sintering pre-batch room → primary mixing (primary mixing) → secondary mixing (secondary mixing) → sintering machine. (2) The belt conveyor operates at a constant flow rate, and the discharge flow rate of each silo is calculated by the batching system based on the comprehensive conveying capacity. After multiple transfers and stacking, the material is mixed.

[0004] Problems with existing practices include: (1) Large land occupation: The secondary material yard, primary mixing chamber, and multiple transfer belts require a large amount of land. (2) Complex personnel: There are many positions for stackers, material yard management, multiple transfers, and maintenance. (3) High economic and energy consumption: Multiple transfers, stacking, and mixing result in additional power consumption, equipment loss, and material loss; the constant flow belt cannot be dynamically adjusted according to demand, further wasting energy. Therefore, how to reduce the land occupation, reduce personnel requirements, and reduce economic and energy consumption in the production of mixed ore for sintering has become an urgent problem to be solved.

[0005] The above content is only used to assist in understanding the technical solution of this application and does not constitute an admission that the above content is prior art. Summary of the Invention

[0010] Based on the designed volume of the ore bin and the proportion, controlling the material feeding and material discharging process of the ore bin;

[0011] When the material status of the ore bin meets the preset completion conditions, a mixing instruction is sent to the mixing equipment to enable the mixing equipment to perform material mixing operations to complete production control.

[0015] The diverter at the belt bifurcation point is controlled according to the mapping relationship to guide the material to the corresponding ore bin.

[0016] In one embodiment, after the step of controlling the diverter at the belt bifurcation point according to the mapping relationship to guide the material to the corresponding ore bin, the method further includes:

[0024] When the discharge valve of the standby silo is open, obtaining the comprehensive material flow rate after the material is replenished, and calculating the deviation value between the comprehensive material flow rate and the preset flow rate threshold;

[0025] When the deviation value is lower than the preset tolerance range, a graded closing instruction is sent to the standby silo, so that the standby silo gradually reduces the opening of the discharge valve until it is closed.

[0026] In one embodiment, the step of controlling the material feeding and material discharging process of the ore bin based on the designed volume of the ore bin and the proportion includes:

[0027] Dividing the material in each ore bin into a preset number of portions according to the proportion and the designed volume of the ore bin;

[0028] When the material division of the ore bin is completed, monitor the material remaining amount in the upstream silo and the capacity status of the downstream mixing equipment;

[0029] When the remaining amount of the material is less than one portion, the feeding operation is performed according to one portion of the material;

[0030] When the capacity state is saturated, suspending the discharge operation of the ore bin;

[0031] When the material remaining amount in any of the ore bins is insufficient or the capacity is saturated, all the ore bins are controlled to synchronously suspend feeding or discharging.

[0032] In one embodiment, when the material state of the ore bin meets the preset completion condition, a mixing instruction is sent to the mixing device so that the mixing device performs a material mixing operation, and the steps of completing production control include:

[0033] Calculating the cumulative feed amount of the ore bin;

[0034] When the cumulative feed amount reaches the preset single-portion material mass, the number of completed portions of the ore bin is counted;

[0035] Calculate the total discharge volume of the ore bin based on the number of completed portions and the preset single-portion material mass;

[0036] When the total discharge amount is equal to the required amount of the corresponding material in the ratio, the material flow detection system is called to verify the discharge data and obtain a verification result;

[0037] When the verification result is consistent and all the ore bins have completed unloading, a mixing instruction is sent to the mixing equipment to enable the mixing equipment to perform material mixing operations to complete production control.

[0038] In one embodiment, before the step of sending the mixing instruction to the mixing device, the method further includes:

[0064] It should be understood that the specific embodiments described herein are merely used to explain the technical solutions of the present application and are not intended to limit the present application.

[0065] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0066] It should be noted that the execution subject of the embodiments of the present application can be a computing service device with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, mobile phone, etc., or an electronic device, control system (computer system), etc. that can implement the above functions. The following uses the control system as an example to illustrate this embodiment and the following embodiments.

[0067] Based on this, the embodiment of the present application provides a method for controlling the production of mixed ore for sintering, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the production control method for mixed ore for sintering in this application.

[0068] In this embodiment, the production control method of mixed ore for sintering includes steps S10 to S40:

[0069] Step S10: Obtain the target total amount of materials required for the sintering operation and the proportion of each material.

[0070] It should be noted that the target total material volume refers to the total weight or volume of the mixed materials planned to be put into this sintering operation. It is directly determined by the production plan and is the benchmark value for all subsequent ingredient calculations. The formula is as follows:

[0071] V 总 =V material 1 + V material 2 + ... + V material n

[0072] The proportion refers to the weight or volume percentage of each type of material (such as iron ore powder, lime powder, coal powder, etc.) that constitutes the total amount of the target material, which is used to ensure that the chemical composition and physical properties of the final sintered ore meet the process requirements.

[0073] Step S20: According to the target total amount of materials and the proportion, the materials are controlled to be transported from the silo to the ore bins corresponding to the sintering batching chamber, and each ore bin stores one type of the materials.

[0074] It should be noted that a silo is a vertical, cylindrical, enclosed storage bin used to temporarily store bulk materials, sorted by category, after being unloaded from ships or trucks and awaiting batching. A sinter batching room is an area where various raw materials are initially weighed and aggregated according to set proportions during the sintering process. A silo is a small or medium-sized storage bin located within the sinter batching room, specifically designed to store a single type of material and equipped with controlled discharge capabilities.

[0075] It can be understood that the control system first calculates the required weight of each material in real time based on the set total feed amount and the weight percentage of each component, and then starts the corresponding silo unloading valve to accurately deliver the materials in sequence through the belt conveyor into the pre-designated ore bins in the sintering batching room. Each ore bin only receives and temporarily stores one type of material until the cumulative weight of the ore bin reaches the required weight. During this period, the valve opening is adjusted through the weighing and flow feedback closed loop to ensure that the incoming material is neither excessive nor insufficient.

[0076] Step S30: Based on the designed volume of the ore bin and the proportion, controlling the material feeding and material discharging process of the ore bin.

[0077] It should be noted that the design volume refers to the upper limit of the internal effective storage space volume determined according to the structural and safety specifications during the construction of the ore bin.

[0078] As an example, the steps of controlling the material feeding and discharging process of the ore bin based on the design volume of the ore bin and the ratio include: dividing the material of each ore bin into a preset number of portions according to the ratio and the design volume of the ore bin; when the material division of the ore bin is completed, monitoring the material remainder of the upstream silo and the capacity status of the downstream mixing equipment; when the material remainder is less than one portion, feeding the material according to one portion; when the capacity status is saturated, suspending the discharging operation of the ore bin; when the material remainder is insufficient or the capacity status is saturated in any of the ore bins, controlling all the ore bins to synchronously suspend feeding or discharging.

[0079] The preset number of portions refers to the number of equal weight portions obtained by dividing the total material stored in the silo according to the proportion and volume. The upstream silo refers to the storage silo located upstream of the silo that feeds the silo. The material remaining refers to the weight of available material currently remaining in the upstream silo. The downstream mixing equipment refers to the device located after the silo that receives and mixes the incoming material from the silo. The capacity status refers to the volume or weight percentage currently occupied by the downstream mixing equipment.

[0080] Please refer to Figure 2 , Figure 2A schematic diagram of the data structure of an ore bin is provided for Example 1 of the method for controlling the production of mixed ore for sintering in this application. The ore bin is designed as a first-in, first-out queue system for precisely controlling and tracking the entry and exit of materials. Each rectangular box in the diagram represents a storage cell in the ore bin, numbered 1 to n. Each cell corresponds to a specific material. Functions f1, f2, f3, etc. represent operations or properties associated with each storage cell, such as discharge rate or material type. When material enters the ore bin, it is first stored in cell 1. As the material is moved and processed, it moves to the next cell according to the first-in, first-out principle. When the material in a cell is completely removed, the cell is marked as available again, ready to receive new material. This structure allows the system to update the material status of each ore bin in real time, ensuring the accuracy and efficiency of the batching process. By configuring an intelligent discharge bin to adjust the discharge rate of each material, the required material can be discharged within a unit time. Real-time data feedback from the material flow detection system verifies the material discharge status to ensure the accuracy of the material ratio.

[0081] First, all the stored materials in each silo are evenly divided into several equal weight portions according to the proportion and the designed volume of the silo. The weight of each portion is solidified into the smallest measurement unit that the system can recognize (the material in the silo is divided into n portions. According to the designed volume W of the silo, each portion of material can be calculated as W / n) to facilitate subsequent portion counting and tracking. Secondly, the upstream silo weighing signal and the downstream mixing equipment material level signal are continuously read during operation to determine the status of both in real time: if the upstream balance is lower than the required weight of one portion, the system immediately sends a one-time refill instruction to the silo to make up the shortfall to a complete portion and then stops, avoiding ratio drift due to fragmented weight; if the material level of the downstream mixing equipment reaches or exceeds the set upper limit, the system immediately closes the discharge valve of the silo to prevent the mixing equipment from overloading or overflowing. Finally, the monitoring logic is based on the principle of "global chain reaction if any ore bin triggers insufficient margin or downstream saturation". Once any ore bin sends the above two signals, the control module immediately sends a pause command to the feed valves and discharge valves of all ore bins synchronously, so that all ore bins stop moving at the same beat, ensuring that the proportion of each material is always locked to avoid imbalance in the ratio.

[0082] Step S40: When the material status of the ore bin meets the preset completion conditions, a mixing instruction is sent to the mixing device to enable the mixing device to perform a material mixing operation to complete production control.

[0083] It should be noted that the preset completion condition refers to the threshold for determining when all materials have been discharged from each silo according to the proportions and the total weight of all materials required for a single blend has been reached. The blending instruction is the signal sent by the control system to the blending equipment to start or allow blending to begin. The blending equipment is a device that receives multiple materials and evenly mixes them.

[0084] As an example, when the material status of the ore bin meets the preset completion conditions, a mixing instruction is sent to the mixing equipment to enable the mixing equipment to perform a material mixing operation, and the steps for completing production control include: calculating the cumulative feed amount of the ore bin; when the cumulative feed amount reaches the preset single material mass, counting the number of completed portions of the ore bin; calculating the total unloading amount of the ore bin based on the completed number of portions and the preset single material mass; when the total unloading amount is equal to the required amount of the corresponding material in the ratio, calling the material flow detection system to verify the unloading data and obtain a verification result; when the verification result is consistent and all the ore bins have completed unloading, sending a mixing instruction to the mixing equipment to enable the mixing equipment to perform a material mixing operation and complete production control.

[0085] The cumulative feed volume refers to the total weight of material actually received by the silo from the start of this batching cycle to the current moment. The preset single-portion material mass refers to the theoretical weight of each portion of material after the total silo storage material is evenly divided according to the design. The number of completed portions refers to the cumulative value of the number of portions that have been completely discharged and recorded from the silo. The total discharge volume is the product of the number of completed portions and the preset single-portion material mass, that is, the total weight of material discharged from the silo. The material flow detection system (material flow scanner) is a detection device that monitors the instantaneous material flow of the belt in real time through weighing or scanning. The discharge data refers to the correspondence between the actual discharged material weight and the theoretical value in each time period recorded by the material flow detection system. The verification result refers to the conclusion of "consistency" or "inconsistency" drawn after comparing the discharge data with the theoretical discharge volume.

[0086] First, the weight values ​​fed back by the weighing sensor are accumulated in real time to obtain the cumulative feed amount of the ore bin since the start of batching; once the value reaches the preset single-portion weight, the system automatically adds 1 to the "number of completed portions" and multiplies the number of portions by the single-portion weight to calculate the total weight of the ore bin unloaded; then the total unloading amount is compared with the corresponding material amount required by the batching ratio. If the two are equal, the material flow detection system is immediately started to check the instantaneous weight data recorded by the belt scale or laser scanning with the theoretical value to generate a verification result; finally, only when the verification result is "consistent" and all ore bins have completed the same verification, a start command is issued to the mixing equipment to start mixing, and the entire production control process is closed at this point.

[0087] As an example, before the step of sending the mixing instruction to the mixing equipment, it also includes: starting the spray device at the transfer point of the transport belt to coarsely mix the falling material with the water mist sprayed by the spray device to obtain a mixed material; obtaining the proportion data of the mixed material detected by the belt composition monitoring unit; and controlling the discharge amount of the feeding device of the ore bin corresponding to the proportion data according to the proportion data and the ratio.

[0088] The transfer point on a conveyor belt is the point where two belts meet and where material drops due to a drop. A spray system is a nozzle and piping system installed at the drop point that sprays water mist onto the material flow. Mixed material refers to a combination of multiple materials that have been coarsely mixed with water mist at the transfer point. A belt composition monitoring unit is a sensor installed on the belt that monitors the composition ratio of materials in real time. The ratio data is the weight percentage of each component in the current mixed material as measured by the monitoring unit. A feeding device is a valve or vibrating feeder at the ore bin outlet that can adjust the discharge rate at a variable speed. The discharge rate is the weight of material released by the feeding device onto the belt per unit time.

[0089] In determining the proportion of each material p i Finally, calculate the discharge volume w of each ore bin fe Then, by controlling the feeding device, the material ratio on the belt at that moment can be achieved to meet the sintering requirements, and the discharge volume w can be calculated. fe The formula is shown below:

[0090]

[0091] Among them, v t Refers to the instantaneous material flow of the belt monitored by the material flow detection system (material flow scanner). It refers to the total proportion of other materials except the materials stored in the current mine (the mine to be calculated), p n Refers to the ratio of materials currently stored in the ore bin.

[0092] If present:

[0093]

[0094] Among them, w pe Indicates the maximum load capacity of the transport belt.

[0095] Then it is necessary to immediately adjust the discharge volume of the entire ore bin. The adjustment formula is as follows:

[0096]

[0097] First, start the spray device at the transfer point of the transport belt (belt drop), and spray water mist evenly at a pressure of 0.3-0.5MPa, so that different material particles are coarsely mixed in advance due to collision and adhesion of water during the 1-2m drop, thereby improving the uniformity in advance and reducing the subsequent secondary mixing load. Secondly, the belt composition monitoring unit scans the mixed material at a frequency of 1Hz and outputs the weight percentage of each component in real time; if the proportion of iron ore powder is 1% lower than the set value (here taking iron ore powder as an example), the system immediately increases the frequency of the ore bin feeding device by 2Hz, and vice versa, so that the deviation returns to within ±0.5% within 30s. Finally, when the proportions of all components fall within the allowable range and the cumulative flow meets the requirements of one mixing, the current discharge volume is locked and continues to run until the mixing instruction is triggered to ensure that the composition of the mixed material entering the second mixing is stable and the proportion is accurate.

[0098] This application can better coordinate resources among various devices by tracking the composition of the material yard in real time, through the linkage control of the material yard and the sintering plant, and by equipping an early warning system to grasp the situation in the warehouse in real time, and better handle the direct control problems of unloading, batching and mixing. The equipment has a simple structure and is easy to install; the maintenance cost is low; there are fewer supporting equipment; and it is stable and reliable.

[0099] Please refer to Figure 3 , Figure 3 The present application provides a schematic diagram of a multi-layer material conveying system in which a secondary material reclaimer scrapes material to form a mixed ore in a traditional manner. In this system, the material moves downward layer by layer from the top ore bin through a series of conveyor belts, and each layer represents a different material or material mixing stage. The top layer is material 1, followed by material 2, and so on, until the bottom layer is material n. As each layer of material moves on the conveyor belt, it is mixed with materials from other ore bins to form the required mixed ore. Although this design allows for the simultaneous processing and mixing of multiple materials, it has several significant disadvantages: (1) Large footprint: Due to the need for multiple ore bins and conveyor belts, the entire system takes up a lot of space, which is particularly disadvantageous in the case of tight land resources. (2) High energy consumption: Multi-layer conveying and frequent material movement lead to a significant increase in energy consumption, which not only increases operating costs but also puts pressure on the environment. (3) Complex operation: The system needs to accurately control the flow and mixing ratio of each layer of material, which requires a complex automated control system and a high degree of manual monitoring, increasing the complexity of operation and the risk of error. (4) High maintenance costs: Numerous mechanical equipment means higher maintenance and repair costs, and also increases the possibility of equipment failure. (5) Inefficiency: The transfer of materials through multiple links may lead to low production efficiency and difficulty in quickly responding to changes in production demand. (6) High staff requirements: Due to the complexity of the operation, more operators and technicians are required to monitor and maintain the entire system.

[0100] This embodiment provides a production control method for mixed ore for sintering. First, the total amount of target materials and the proportion of each material are calculated at one time according to the sintering plan, and based on this, each type of material is directly sent from the silo to the corresponding ore bin in the sintering batching room, eliminating the need for secondary material yard transportation, shortening the process and reducing land occupation. Secondly, the capacity of each ore bin is cut into a fixed number of portions according to the proportion, and the "one portion is replenished when missing, one portion is stopped when full" is achieved through real-time monitoring of the upstream surplus and downstream capacity, and all ore bins are started and stopped synchronously, so that the proportion is always accurate and manual intervention is reduced. Finally, when the cumulative unloading amount of each ore bin is completely consistent with the proportion requirement, the material flow detection and verification is triggered and then a mixing instruction is sent to the mixing equipment to complete the production control, further eliminating one mixing process. This embodiment reduces the floor space occupied in the production of mixed ore for sintering, reduces personnel requirements, and reduces economic and energy consumption.

[0101] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above embodiment 1 can be referred to the above introduction and will not be described in detail later. Figure 4 , Figure 4 This is a flow chart of the second embodiment of the production control method for mixed ore for sintering of the present application. Step S20 of the production control method for mixed ore for sintering includes steps S21 to S23:

[0102] Step S21: When the total amount of material stored in the silo reaches the target total amount of material, the discharge valve of the silo is controlled to open so that the material in the silo enters the conveyor belt.

[0103] It should be noted that the discharge valve refers to a device installed at the bottom outlet of the silo that controls the outflow of materials through opening and closing actions.

[0104] It is understandable that when the system confirms that the weight of the material in the silo has met the target total amount required for this sintering, it immediately sends a full-open command to the unloading valve. The valve is fully opened within 2 seconds, and the material is poured onto the conveyor belt below at a constant flow rate. The belt continuously sends the material flow to the sintering batching room at a set speed, ensuring that the subsequent batching links obtain sufficient raw materials in a timely manner.

[0105] Step S22: When the material enters the conveyor belt, a mapping relationship between the material and the ore bin is determined according to the ratio.

[0106] It should be noted that the mapping relationship refers to the one-to-one matching relationship established between each material and its unique corresponding ore bin, ensuring that each type of material accurately enters its respective ore bin during subsequent batching.

[0107] It is understandable that in this embodiment, first, the system uses a belt scale to weigh and identify the material in real time when it is just put on the transport belt, and synchronously reads the formula table through the PLC, solidifying the iron ore powder, lime powder, coal powder, etc. into a one-to-one mapping table with ore bin 1, ore bin 2, ore bin 3, etc. in turn to ensure that the subsequent material distribution is correct. Secondly, before the belt reaches the bifurcation point, the material label is checked again by the barcode scanner. After confirming that it is consistent with the mapping table, the corresponding flap is controlled to switch accurately within 0.5s, so that the material enters the target ore bin along the correct chute to prevent mixing. Finally, each time a material distribution is completed, the system writes the actual bin number and mapping record into the log and sends it back to the host computer for traceability. If a deviation is found, the alarm will be immediately shut down to ensure long-term stability of the ratio.

[0108] Step S23: controlling the diverter at the belt bifurcation point according to the mapping relationship to guide the material to the corresponding ore bin.

[0109] It's important to note that a belt bifurcation is the point where a conveyor belt branches into two or more belts along its path. A diverter is a mechanical device installed at this intersection that, through a swinging or flipping motion, directs material to a specific branch belt.

[0110] It can be understood that, first, when the front end of the material reaches the photoelectric switch 2m before the belt bifurcation point and is triggered, the control system sends the target angle command to the diverter servo driver at a 50ms cycle. The diverter completes the swing angle switch within 0.3s, allowing the material to fall into the designated ore bin along the set chute, avoiding misplacement. Secondly, after the diverter reaches its position, it feedbacks the angle signal. If the control system compares it correctly, it marks this action as completed and updates the queue. If the next material mapping is different, the above switching is repeated to ensure that all materials are accurately stored in the bin during the continuous operation of the entire belt.

[0111] The same unloading belt unloads several ore bins at the same time. The mass of the material in the kth ore bin at time t is W k (t):

[0112]

[0113] Among them, W k (t0) is the material mass of the ore bin at time t0; S k To determine the position, when the conveyor belt is unloading the silo at time t, S k =1, otherwise S k =0; w(t) is the unloading flow of the conveyor belt; is the discharge flow of the silo at time t.

[0114] When the following equation is satisfied, it means that one portion of material has been fully unloaded, and a signal is sent to the first mixer to inform that the material proportioning is completed. The material can then enter the first mixer to form a mixed material:

[0115]

[0116] Where n refers to the preset number of portions, and W refers to the designed volume of the ore bin.

[0117] When unloading, it should be ensured that the unloading amount is greater than the discharge amount of the ore bin at that moment, and the unloading amount of the ore bin at time t is less than the maximum storage capacity of the ore bin (to ensure that the ore bin will not be unloaded empty and thus affect the proportion, and at the same time, the unloading amount per unit time should not be too large to ensure that the ore bin will not overflow and be blocked), that is:

[0118] And W k (t) <W

[0119] At this time, the material in each silo of the pre-batch room must be updated and compared with the silo material data in real time, and the discharge amount in the silo is controlled according to the required discharge amount of the above formula. If the above formula is satisfied, the material can be directly delivered from the silo to the sintering batching room.

[0120] When the following equations are met, the ore bin completes unloading of Material 1 (Material 1 here refers to the amount of material required for a single mixing step). Simultaneously, real-time data feedback from the material flow detection system verifies the material unloading status. When both conditions are met, the computer control system issues a stop-unloading command, and the first mixing step begins preparations for mixing.

[0121]

[0122] Among them, V 物料1 It represents the total cumulative amount of material 1, that is, the total amount of material 1 discharged through the discharge flow from the starting time to time t.

[0123] As an example, after the step of controlling the diverter at the belt bifurcation point according to the mapping relationship to guide the material to the corresponding ore bin, it also includes: obtaining the material flow detected by the material flow detection system installed on the conveyor belt; when the material flow is lower than the preset flow threshold, controlling the spare silo to add material to the conveyor belt; when the material receiving amount of the ore bin reaches the designed volume, controlling the unloading valve to close.

[0124] Please refer to Figure 5 , Figure 5A schematic diagram of the ore bin batching structure provided for Example 2 of the production control method for mixed ore for sintering of this application, wherein 1 represents an ore bin, each of which stores a specific material. There are seven ore bins in total, marked as 1# ore bin to 7# ore bin. 2 represents a feeding device, which is located under each ore bin and is responsible for feeding the material in the ore bin into the conveyor belt at a set flow rate. 3 is a material flow scanner, which is installed in front of the feeding device and is used to detect and measure the flow of materials in real time to ensure that the materials enter the conveyor belt in a predetermined proportion. 4 is a conveyor belt, which transports materials from different ore bins to the next process, such as a sintering batching room. The entire system achieves accurate material proportioning by precisely controlling the discharge amount of each feeding device to meet the needs of sintering production.

[0125] Material flow rate refers to the weight of material passing through the belt per unit time. The preset flow threshold is the lowest instantaneous flow rate setting allowed by the system. A backup silo is an additional storage bin of the same material that can be used immediately when the main silo's flow rate is insufficient. Material reception capacity refers to the total weight of material currently received by the silo.

[0126] First, the control system reads the instantaneous weight value of the material flow detection system with a cycle of 100ms. If it is lower than the preset flow threshold (three times in a row), it immediately calculates the shortfall and outputs the valve opening using the PID algorithm. At the same time, it sends an opening instruction to the electric discharge valve of the spare silo. The valve opens linearly to the target position within 2s, allowing the belt flow to return to stability within 10s, avoiding material breakage or ratio fluctuations. Secondly, the control system accumulates the ore bin weighing signal in real time. When the accumulated value is 5% away from the design volume, it slows down in advance. When the remaining value is 1%, the discharge valve is completely closed to prevent overshoot and overflow. Finally, the control system writes the material replenishment and valve stop events into the log and transmits them back to the host computer for subsequent batch traceability and optimization.

[0127] As an example, when the material flow is lower than a preset flow threshold, the step of controlling the standby silo to feed the transport belt includes: when the material flow is lower than the preset flow threshold, calculating the shortfall between the material flow and the preset flow threshold; matching a standby silo of the same type based on the material type corresponding to the material flow; generating a feeding rate instruction according to the shortfall to control the discharge valve of the standby silo to open at the opening specified by the feeding rate instruction; when the discharge valve of the standby silo is open, obtaining the comprehensive material flow after feeding, and calculating the deviation between the comprehensive material flow and the preset flow threshold; when the deviation is lower than the preset tolerance range, sending a graded closing instruction to the standby silo to gradually reduce the opening of the discharge valve until it is closed.

[0128] Shortage is the weight difference between the actual material flow and the preset flow threshold. The refill rate command is the control signal generated by the control system to set the valve opening and instantaneous flow rate for the backup silo discharge valve. The total material flow rate is the total instantaneous material flow detected on the conveyor belt when the primary and backup silos are simultaneously being fed. The preset tolerance range is the weight range within which the total material flow rate is allowed to fluctuate around the preset flow threshold. The stepped closing command is a gradual closing command in which the control system gradually reduces the valve opening until it is fully closed.

[0129] First, the control system collects belt weighing data every second, compares it with a preset flow threshold, calculates the shortfall, and multiplies it by a safety factor of 1.1 to obtain the required replenishment weight. It then searches the database to select a spare silo of the same type and outputs the opening percentage to its electric control valve. The valve linearly opens to this percentage within 2 seconds, rapidly increasing the flow rate and preventing material shortages. Secondly, after the valve opens, the control system accumulates the instantaneous flow rates of the main and backup silos in a 100ms cycle to obtain a combined value. The deviation from the threshold is calculated in real time. If the deviation remains greater than zero, the valve opening is slightly increased using the PID algorithm. If the deviation is less than zero, the valve is immediately prepared to close to ensure neither overshoot nor underfill occurs. Finally, when the deviation falls within the preset tolerance of ±1%, the control system initiates a graded closing command, reducing the valve opening by 10% every 2 seconds until it is fully closed after 5 steps. This prevents momentary flow interruptions from causing belt shock. The entire process data is also recorded for subsequent batch optimization.

[0130] In this embodiment, when the total amount of material in the silo is confirmed to have reached the target total amount through the weighing sensor, the unloading valve is opened to allow the material to flow smoothly into the conveyor belt, ensuring timely supply of materials and avoiding production interruptions. After the material enters the belt, the mapping relationship between the material and the ore bin is quickly determined according to the ratio, and accurate material distribution is achieved by reading the formula table and matching the material labels to prevent mismatching and ensure accurate material distribution. Finally, the diverter at the bifurcation point of the belt is accurately controlled based on the mapping relationship to guide the material to the corresponding ore bin, and the diverter quickly switches angles to ensure that the material enters the bin accurately. This embodiment reduces manual intervention, improves the efficiency and accuracy of material distribution, and ensures the stability and continuity of the sintering production process.
