Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of blast furnaces, and in particular to a method and device for controlling screening of a bunker, a piece of equipment, and a medium. BACKGROUND

[0002] Raw materials used by a blast furnace generally include sintered ore, coke, pellet ore, raw ore, auxiliary materials, and the like. These raw materials are screened and weighed by a slot-under system according to the needs of blast furnace smelting, and then sent to the blast furnace for smelting. The slot-under raw material system of the blast furnace generally has multiple bunkers for each type of raw material, at least one bunker for a raw material with a small usage, and more than ten bunkers for a raw material with a large usage. Each bunker is provided with a screening device and a weighing hopper. After the raw materials are screened, the slot-under electronic weighing equipment weighs the raw materials to reach the required amount of feeding, and then the raw materials are transported to the blast furnace for smelting by a belt conveying system.

[0003] The slot-under bunkers of the blast furnace generally have several dozen bunkers, each with a volume of about several hundred cubic meters. The bunkers are distributed on a plane of hundreds of meters. The bunkers are usually arranged in rows, and one row usually has several dozen bunkers. A conveying belt is arranged at the lowermost part of the bunkers, mainly to facilitate the transportation of the furnace charge, and also to save resources. After the furnace charge of multiple bunkers is screened and weighed, it is transported to the blast furnace by the same belt. At present, most domestic blast furnaces have only one conveying belt for transporting the furnace charge to the interior of the blast furnace.

[0004] However, because the blast furnace uses multiple types of furnace charge, and each type of furnace charge has multiple bunkers, and the blast furnace is in a continuous feeding state, the slot-under bunkers of the blast furnace are in a running state at all times. The configuration of the furnace charge for the blast furnace, the screening efficiency is low, the vibrating screen is in operation for a long time, and the conveying belt is in operation for a long time, which greatly wastes electric energy and lowers the screening efficiency. The usage of different furnace charges, how to allocate the bunkers, and how to set the screening speed of the bunkers all depend on the random allocation of the operators, which seriously restricts the improvement of the screening efficiency. SUMMARY

[0005] The present application provides a method and device for controlling screening of a bunker, a piece of equipment, and a medium, to realize reasonable allocation of screening configuration information and reasonable determination of discharging time nodes, thereby improving the screening efficiency.

[0032] Example 1

[0033] Figure 1 This is a flowchart of a silo screening control method provided in Embodiment 1 of the present invention. This embodiment is applicable to the control of blast furnace silos. The method can be executed by a silo screening control device, which can be implemented in hardware and / or software and can be configured in an electronic device. Figure 1 As shown, the method includes:

[0034] S110. Obtain the preset blast furnace material system, preset loading time, used furnace materials and usage of each furnace material, silo configuration information of the silo storing furnace materials, and belt operation configuration information of the conveyor belt.

[0035] In the embodiment, the preset blast furnace burden system can be understood as a system for performing a preset burden discharging sequence and burden discharging angle. The preset charging time can be understood as a time for charging burden on the top of the blast furnace and completely entering the blast furnace for smelting after discharging, which can be considered as the longest time limit for transportation. The burden can be understood as raw materials required for smelting in the blast furnace, such as sinter, coke, pellet and ore. The usage of each burden can be understood as the usage of each burden for smelting. The burden bin can be understood as a bin for storing burden, and there can be multiple bins for each burden and arranged at different positions of the burden conveying belt. The bin configuration information can be understood as information related to the configuration of the bin, such as the storage amount of burden in the bin and the position of the bin. The burden conveying belt can be understood as a belt for transporting burden in different bins to the blast furnace. The belt running configuration information can be understood as configuration information when the belt is running, such as the running speed of the belt.

[0036] Specifically, the controller can obtain the preset blast furnace burden system, the preset charging time, the used burden, the usage of each burden, the bin configuration information of the bin for storing burden and the belt running configuration information of the burden conveying belt.

[0037] S120, for each burden, determining, according to the usage of the burden, the bin configuration information of the bin for storing burden and the belt running configuration information, a to-be-screened bin meeting a screening condition and a transportation time difference between the to-be-screened bin and an adjacent to-be-screened bin.

[0038] In the embodiment, the screening condition can be understood as a condition for determining whether the storage amount in the bin can meet the usage. The to-be-screened bin can be understood as a bin that needs to be screened. The adjacent to-be-screened bin can be understood as a previous bin or a next bin adjacent to the to-be-screened bin according to the distance between the bin and the blast furnace. The transportation time difference can be understood as a time for transporting from the to-be-screened bin to the adjacent to-be-screened bin.

[0039] Specifically, for each burden, the controller can determine, according to the bin configuration information of the bin for storing burden, whether the corresponding burden is stored in each bin, so as to screen the bin storing the burden as the to-be-screened bin meeting the screening condition. The controller can determine the position of each to-be-screened bin and the distance between each to-be-screened bin and the adjacent adjacent to-be-screened bin through the bin configuration information of the to-be-screened bin. Since the burden between each to-be-screened bin is conveyed through the conveying belt, the controller can determine the transportation time difference between the two adjacent to-be-screened bins in combination with the running speed of the conveying belt in the belt running configuration information.

[0040] S130, determining, according to each transportation time difference, a preset screened burden flow size and a preset charging time, screening configuration information corresponding to each to-be-screened bin.

[0041] In the embodiment, the preset screening flow size can be understood as the flow size when each burden is screened, and the flow size can be adjusted by adjusting the valve opening degree. The screening configuration information can be understood as.

[0042] Specifically, the controller can determine the screening speed according to the distance of the farthest burden bin from the blast furnace and the preset charging time, to ensure that the time from the completion of screening of the farthest burden bin to the transportation to the top of the blast furnace is less than the preset charging time. The controller can first determine the average screening amount according to the usage amount of the burden and the number of the bins, and then correct the average screening amount of each bin to be screened according to the transportation time difference between each bin to be screened and the preset screening flow size, to obtain the screening amount of each bin to be screened, so as to take the screening amount and the screening speed as the screening configuration information corresponding to each bin to be screened.

[0043] S140, for each bin to be screened, determining a discharging time of opening the bin to be screened to put the corresponding burden into the conveying belt according to a previous screening amount of a previous bin to be screened adjacent to the bin to be screened.

[0044] In the embodiment, the previous bin to be screened can be understood as the bin to be screened adjacent to the bin to be screened and closer to the blast furnace. The previous screening amount can be understood as the screening amount of the previous bin to be screened. The discharging time can be understood as the time node of discharging into the conveying belt.

[0045] Specifically, for each bin to be screened, the controller can sort the bins to be screened according to the distance from the blast furnace from near to far, take the first bin to be screened adjacent to the bin to be screened and closer to the blast furnace as the previous bin to be screened, and determine the screening progress of the previous bin to be screened according to the previous screening amount of the previous bin to be screened, so as to take the time when the previous bin to be screened has the same amount of burden to be screened as the transportation time difference as the discharging time of opening the bin to be screened to put the corresponding burden into the conveying belt.

[0046] S150, controlling each bin to be screened based on the preset blast furnace burden, the screening configuration information and the discharging time.

[0047] Specifically, the controller can control each bin to be screened according to the screening configuration information of the corresponding burden bin according to the corresponding burden placement order and the corresponding burden bin to be screened in the burden placement order of the preset blast furnace burden, and control the burden placed after screening in the bin to be screened to be put into the conveying belt in turn according to the corresponding discharging time.

[0048] The technical scheme of the embodiment of the present application comprises the following steps: obtaining a preset blast furnace burden system, a preset charging time, used furnace burdens, the usage amount of each furnace burden, the stockyard configuration information of the stockyard storing the furnace burden, and the belt operation configuration information of the material conveying belt; for each furnace burden, determining the stockyard to be screened that meets the screening condition and the transportation time difference between each stockyard to be screened and the adjacent stockyard to be screened according to the usage amount of the furnace burden, the stockyard configuration information of the stockyard storing the furnace burden, and the belt operation configuration information; determining the screening configuration information corresponding to each stockyard to be screened according to each transportation time difference, a preset screening flow size, and the preset charging time; for each stockyard to be screened, determining the discharging time of the corresponding furnace burden into the material conveying belt by opening the stockyard to be screened according to the previous screening amount of the previous stockyard to be screened adjacent to the stockyard to be screened; and controlling each stockyard to be screened based on the preset blast furnace burden system, each screening configuration information, and each discharging time. By reasonably allocating the screening amount and the discharging time, the safety risk caused by the stacking of the furnace burden on the belt is eliminated, the belt deviation probability is reduced, the belt material leakage phenomenon is reduced, and the operation efficiency is improved.

[0049] Embodiment two

[0050] Figure 2 A flowchart of a stockyard screening control method provided by the second embodiment of the present application is shown in FIG. 2. The present embodiment is a further refinement of the above-mentioned embodiment. As shown in FIG. 2, the method comprises the following steps. Figure 2

[0051] S201, obtaining a preset blast furnace burden system, a preset charging time, used furnace burdens, the usage amount of each furnace burden, the stockyard configuration information of the stockyard storing the furnace burden, and the belt operation configuration information of the material conveying belt.

[0052] S202, for each furnace burden, determining the stockyard to be screened that meets the screening condition according to the usage amount of the furnace burden and the furnace burden amount in the stockyard configuration information of the stockyard storing the furnace burden.

[0053] In the present embodiment, the furnace burden amount can be understood as the amount of the furnace burden contained in the stockyard.

[0054] Specifically, for each furnace burden, the controller can determine whether there is enough furnace burden in each stockyard according to the usage amount of the furnace burden and the furnace burden amount in the stockyard configuration information of each stockyard storing the furnace burden, and take the stockyard with sufficient furnace burden amount as the stockyard to be screened that meets the screening condition.

[0055] ​For example, according to the batch weight of the ore into the blast furnace (the weight of a single batch of ore), the usage amount M1 of sintered ore A, the usage amount M2 of raw ore, and the usage amount M3 of ball ore are determined. According to the number of ore bins under the blast furnace slot filled with sintered ore A, for example, there are 5 ore bins under the slot to be screened filled with sintered ore A, and the 5 ore bins to be screened filled with sintered ore A are arranged at random positions (it is possible that the sintered ore bins in the middle are temporarily empty); according to the number of ore bins under the blast furnace slot filled with raw ore S, for example, there are 2 ore bins under the slot filled with raw ore S, and the 2 ore bins to be screened filled with raw ore S are arranged at random positions (it is possible that the raw ore bins in the middle are temporarily empty); according to the number of ore bins under the blast furnace slot filled with ball ore B, for example, there are 2 ore bins under the slot filled with ball ore B, and the 2 ore bins to be screened filled with ball ore B are arranged at random positions (it is possible that the ball ore bins in the middle are temporarily empty); according to the usage amount M4 of each batch of coke, combined with the number of ore bins filled with coke, for example, there is a coke bin, and 3 ore bins to be screened filled with coke are used for distribution. Combined with the discharging sequence recorded in the preset blast furnace burden, the burden can be initially set as 5A2S2B+3K.

[0056] S203, according to the distance between the ore bin discharging point in the ore bin configuration information of each to-be-screened ore bin and the blast furnace, the ore bin sequence information between each to-be-screened ore bin is determined.

[0057] In this embodiment, the ore bin discharging point can be understood as the point where the burden in the ore bin falls onto the conveying belt after screening and weighing. The ore bin sequence information can be understood as the sequence of the distance between the ore bin and the blast furnace.

[0058] Specifically, the controller can sort the distance between the ore bin discharging point in the ore bin configuration information of each to-be-screened ore bin and the blast furnace according to the order from near to far to obtain the ore bin sequence information.

[0059] For example, regardless of the burden used, the controller can first determine the largest amount of burden variety A (assuming sintered ore), the second largest amount of burden variety S (assuming raw ore), the third largest amount of burden variety B (assuming ball ore), and so on. The burden to be used is sorted according to the usage weight. The blast furnace burden bin is sorted, and according to the distance between the ore bin discharging point (the point where the burden in the ore bin falls onto the conveying belt after screening and weighing) and the blast furnace, the sintered ore bin is sorted as A1, A2, A3, A4, A5, and so on; the raw ore bin is sorted as S1, S2, S3, S4, S5, and so on; the ball ore bin is sorted as B1, B2, B3, B4, B5, and so on; the coke bin is sorted as K1, K2, K3, K4, K5, and so on; and so on. The ore bins corresponding to how many kinds of burden are sorted.

[0060] S204, for each to-be-screened ore bin, according to the ore bin sequence information, the next to-be-screened ore bin adjacent to the to-be-screened ore bin is determined.

[0061] In the embodiment, the next-to-be-screened bunker can be understood as the to-be-screened bunker adjacent to the to-be-screened bunker and farther away from the blast furnace.

[0062] Specifically, for each to-be-screened bunker, the controller can find out the first to-be-screened bunker adjacent to the to-be-screened bunker and farther away from the blast furnace as the next-to-be-screened bunker according to the bunker sequence information.

[0063] For example, when the to-be-screened bunker is A1, the next-to-be-screened bunker is A2; when the to-be-screened bunker is A2, the next-to-be-screened bunker is A3, and the previous-to-be-screened bunker is A1, and so on.

[0064] S205, determining the transportation time difference between the to-be-screened bunker and the next-to-be-screened bunker according to the belt running configuration information and the bunker configuration information of the next-to-be-screened bunker.

[0065] Specifically, the controller can determine the distance between the two bunkers according to the belt running speed in the belt running configuration information and the bunker configuration information of the next-to-be-screened bunker and the bunker configuration information of the to-be-screened bunker, and then determine the transportation time difference between the to-be-screened bunker and the next-to-be-screened bunker according to the distance and the belt running speed.

[0066] Further, on the basis of the above embodiment, the step of determining the transportation time difference between the to-be-screened bunker and the next-to-be-screened bunker according to the belt running configuration information and the bunker configuration information of the next-to-be-screened bunker can be further optimized as follows:

[0067] extracting the belt running speed in the belt running configuration information; determining the distance value between the to-be-screened bunker and the next-to-be-screened bunker according to the next-bunker dropping point position in the bunker configuration information of the next-to-be-screened bunker and the bunker dropping point position in the bunker configuration information of the to-be-screened bunker; and determining the transportation time difference between the to-be-screened bunker and the next-to-be-screened bunker according to the distance value and the belt running speed.

[0068] In the embodiment, the belt running speed can be understood as the speed when the material conveying belt is running. The next-bunker dropping point position can be understood as the point where the furnace burden is dropped onto the material conveying belt after being screened and weighed in the next-to-be-screened bunker. The distance value can be understood as the interval distance between the to-be-screened bunker and the next-to-be-screened bunker.

[0069] Specifically, the controller can extract the belt running speed in the belt running configuration information, determine the distance value between the to-be-screened bunker and the next-to-be-screened bunker according to the next-bunker dropping point position in the bunker configuration information of the next-to-be-screened bunker and the bunker dropping point position in the bunker configuration information of the to-be-screened bunker, and the controller can divide the distance value by the belt running speed to obtain the transportation time difference between the to-be-screened bunker and the next-to-be-screened bunker.

[0070] For example, the screening time of the sinter closest to the blast furnace is ta1, and the screening times of the sinter in the sinter bins A2-A5 are ta2, ta3, ta4 and ta5 in sequence; the screening times of the green ore in the green ore bins S1 and S2 are ts1 and ts2 in sequence; the screening times of the ball ore in the ball ore bins B1 and B2 are tb1 and tb2 in sequence. The running time of the material on the conveying belt. The time for transporting the coke in each selected coke bin to the charging bin on the top of the blast furnace is calculated, and the transportation time of the coke in the closest coke bin K1 is tk1, and the transportation times of the coke in the other selected coke bins are tk2 and tk3 in sequence. The running speed of the belt is a fixed value V. The distance between the selected adjacent sinter bins A2 and A1 is L1, the distance between the selected adjacent sinter bins A3 and A2 is L2, the distance between the selected adjacent sinter bins A4 and A3 is L3, and the distance between the selected adjacent sinter bins A5 and A4 is L4. The transportation time difference between the selected adjacent sinter bins A1, A2, A3, A4 and A5 is ta2-ta1=L1 / V, ta3-ta2=L2 / V, ta4-ta3=L3 / V and ta5-ta4=L4 / V. The distance between the selected adjacent green ore bins S1 and S2 is L5, and the transportation time difference between the selected adjacent green ore bins S1 and S2 is ts2-ts1=L5 / V. The distance between the selected adjacent ball ore bins B1 and B2 is L6, and the transportation time difference between the selected adjacent ball ore bins B1 and B2 is tb2-tb1=L6 / V. The distance between the selected adjacent coke bins K1 and K2 is L7, and the distance between the selected adjacent coke bins K2 and K3 is L8. The transportation time difference between the selected adjacent coke bins K1 and K2 is tk2-tk1=L7 / V, and the transportation time difference between the selected adjacent coke bins K2 and K3 is tk3-tk2=L8 / V. After the selected sinter bins are selected, the distance between the selected sinter bins is fixed. The time for the furnace charge to be completely charged into the blast furnace after being charged into the charging bin on the top of the blast furnace is T (under normal production conditions, the charging bin on the top of the blast furnace is required to be continuously charged with the furnace charge, and the time for the furnace charge in the charging bin on the top of the blast furnace to be completely charged into the blast furnace is different).

[0071] In S206, the screening amount corresponding to each sinter bin is determined according to the use amount, the preset screening flow size and the transportation time difference.

[0072] Further, on the basis of the above embodiment, the step of determining the screening amount corresponding to each sinter bin according to the use amount, the preset screening flow size and the transportation time difference can be optimized as follows:

[0073] The average screening amount of the sinter bin is determined according to the use amount and the total number of the sinter bins. For each sinter bin, the screening amount difference between the sinter bin and the adjacent previous sinter bin is determined according to the average screening amount, the preset screening flow size and the transportation time difference. The screening amount corresponding to each sinter bin is determined according to the screening amount difference and the use amount.

[0074] In the embodiment, the total quantity can be understood as the number of all the to-be-screened bins corresponding to the furnace burden. The average screening quantity can be understood as the screening quantity of each to-be-screened bin by using the quantity to divide equally. The screening quantity difference can be understood as the difference between the screening quantities of two to-be-screened bins.

[0075] Specifically, the controller can divide the usage quantity by the total number of to-be-screened bins to obtain the average screening quantity of each to-be-screened bin in the preliminary division. Since each to-be-screened bin is at a distance from each other, the screening weight of the to-be-screened bin arranged in the order from near to far of the blast furnace should be gradually reduced, and the average screening quantity can be adjusted by the transportation time difference. Therefore, for each to-be-screened bin, the controller can determine the screening quantity difference between the to-be-screened bin and the adjacent previous to-be-screened bin according to the average screening quantity, the preset screening flow size, and the transportation time difference, and further determine the relationship between each to-be-screened bin and the first to-be-screened bin closest to the blast furnace through the screening quantity differences. The screening quantity of each to-be-screened bin is accumulated through the relationship with the first to-be-screened bin, and the accumulated value is equal to the usage quantity, so as to determine the corresponding screening quantity of each to-be-screened bin.

[0076] For example, the total weight of the sintered ore screening is M1, the average screening amount of the five sintered ore bins to be screened is M1 / 5, and the preset screening flow size of each furnace charge screening belongs to a fixed value TH (the valve opening can be adjusted to adjust the flow size in each time stage), and the screening amount per unit time is (M1 / 5) / TH; because there is a distance between each bin to be screened, the screening weight of A1, A2, A3, A4, and A5 gradually decreases, the screening amount of A1 is less than that of A2 (M1 / 5) / TH*(L1 / V), the screening amount of A2 is less than that of A3 (M1 / 5) / TH*(L2 / V), the screening amount of A3 is less than that of A4 (M1 / 5) / TH*(L3 / V), and the screening amount of A4 is less than that of A5 (M1 / 5) / TH*(L4 / V), that is, P1 (the screening amount of the first sintered ore bin to be screened) + P2 (the screening amount of the second sintered ore bin to be screened) + P3 (the screening amount of the third sintered ore bin to be screened) + P4 (the screening amount of the fourth sintered ore bin to be screened) + P5 (the screening amount of the fifth sintered ore bin to be screened) = M1 (the sintered ore usage amount); that is, P1 + (P1 + (M1 / 5) / TH*(L1 / V)) + ((P1 + (M1 / 5) / TH*(L1 / V)) + (M1 / 5) / TH*(L2 / V)) + (((P1 + (M1 / 5) / TH*(L1 / V)) + (M1 / 5) / TH*(L2 / V)) + (M1 / 5) / TH*(L3 / V)) + ((((P1 + (M1 / 5) / TH*(L1 / V)) + (M1 / 5) / TH*(L2 / V)) + (M1 / 5) / TH*(L3 / V)) + (M1 / 5) / TH*(L4 / V))) = M1, P1 is calculated according to the formula, and P2, P3, P4, and P5 are obtained synchronously. Similarly, the screening amounts of the two bins of raw ore S, the two bins of ball ore B, and the three bins of coke K can be obtained.

[0077] In S207, the farthest bin to be screened is determined according to the distance from the blast furnace, and the screening speed of the bin to be screened is determined according to the target screening amount of the farthest bin to be screened, the preset tank filling time, and the belt running speed in the belt running configuration information.

[0078] In this embodiment, the farthest bin to be screened can be understood as the bin to be screened farthest from the blast furnace. The screening speed can be understood as the speed for screening the furnace charge.

[0079] Specifically, the controller can determine the farthest to-be-screened bin farthest from the blast furnace among the to-be-screened bins, and require that the time from screening completion of the blast furnace charge in the farthest to-be-screened bin to transportation to the top of the blast furnace be less than the preset charging time. Then, the controller can construct an equation by using the target screening amount of the farthest to-be-screened bin, the distance between the farthest to-be-screened bin and the blast furnace, the belt running speed, the unknown screening speed, and the preset charging time, and determine the screening speed of the to-be-screened bin. The screening speed of all to-be-screened bins corresponding to the blast furnace charge can be set as the screening speed determined by the farthest to-be-screened bin.

[0080] S208, the screening speed and each screening amount are taken as the screening configuration information of each corresponding to-be-screened bin.

[0081] S209, for each to-be-screened bin, a target screening amount difference value is determined according to a target transportation time difference between the to-be-screened bin and a previous to-be-screened bin and a preset screening material flow size.

[0082] In this embodiment, the target screening amount difference value can be understood as the difference value of the screening amount between two to-be-screened bins. The target transportation time difference can be understood as the time difference value from transporting the material from the to-be-screened bin to the position of the previous to-be-screened bin.

[0083] Specifically, for each to-be-screened bin, the controller can obtain the target screening amount difference value by multiplying the target transportation time difference between the to-be-screened bin and the previous to-be-screened bin by the preset screening material flow size.

[0084] S210, a target screening node amount of the previous to-be-screened bin is determined according to the target screening amount difference value and a previous screening amount of the previous to-be-screened bin.

[0085] In this embodiment, the target screening node amount can be understood as a node for determining when the to-be-screened bin starts to discharge the material to the material transportation belt.

[0086] Specifically, the controller can determine the target screening node amount of the previous to-be-screened bin by subtracting the target screening amount difference value from the previous screening amount.

[0087] S211, a screening node time required for the previous to-be-screened bin to screen the target screening node amount is determined according to an actual screening speed of the previous to-be-screened bin and the target screening node amount.

[0088] In this embodiment, the actual screening speed can be understood as the speed when the previous to-be-screened bin is screening. The screening node time can be understood as the time node of discharging the material by the to-be-screened bin.

[0089] Specifically, the controller can obtain the screening node time required for the previous to-be-screened bin to screen the target screening node amount by dividing the target screening node amount by the actual screening speed of the previous to-be-screened bin.

[0090] S212, taking the screening node time as the discharging time of the corresponding furnace burden into the material conveying belt from the discharging bin to be screened.

[0091] Specifically, the controller can take the screening node time as the discharging time of the corresponding furnace burden into the material conveying belt from the discharging bin to be screened. That is, timing is performed during screening of the previous discharging bin to be screened, and when the screening node time is reached, the discharging bin to be screened is opened to discharge the corresponding furnace burden into the material conveying belt.

[0092] For example, the opening degree of the bin valve is fixed. When A1 is full of burden with a weight of P1, the valve is opened to discharge the burden into the conveying belt. At this time, A2, A3, A4, and A5 are not full and are still running. When A1 bin still has TH*L1 / V of sinter, A2 is opened to discharge the burden into the conveying belt. When A2 bin still has TH*L2 / V of sinter, A3 is opened to discharge the burden into the conveying belt. When A3 bin still has TH*L3 / V of sinter, A4 is opened to discharge the burden into the conveying belt. When A4 bin still has TH*L4 / V of sinter, A5 is opened to discharge the burden into the conveying belt, until A5 is empty. The burden is just connected on the conveying belt. According to this method, the screening weight of each bin of raw ore, ball ore, and coke is set synchronously.

[0093] As a first optional embodiment of the first embodiment, after the control of each discharging bin based on the preset blast furnace burden, each screening configuration information, and each discharging time, the method further includes:

[0094] When it is detected that there is a discharging bin to be accelerated that meets the accelerated discharging condition, the opening degree of the valve of the discharging bin to be accelerated is adjusted.

[0095] In this embodiment, the accelerated discharging condition can be understood as a condition for judging whether the discharging bin to be screened needs to be accelerated.

[0096] Specifically, when the previous discharging bin to be screened has been discharged, but the discharging bin to be screened has not been screened, it is detected that the discharging bin to be screened meets the accelerated discharging condition. At this time, the discharging bin to be screened is taken as the discharging bin to be accelerated. In order to ensure that the burden is just connected on the material conveying belt, the opening degree of the valve of the discharging bin to be accelerated can be adjusted at this time, and the preset screening flow size is increased by increasing the opening degree of the valve.

[0097] For example, if A1 is empty, but A2 has not been screened, the opening degree of the A2 valve is adjusted, the opening degree of the valve is increased, the TH value of A2 is increased, and the burden is just connected with the burden of the previous discharging bin to be screened on the material conveying belt.

[0098] Because coke and ore are separately put into the blast furnace during the smelting process, when the upper tank of the furnace top is filled with coke and is opened to put into the lower tank, the under-tank system starts to screen and weigh the ore; when the upper tank of the furnace top is filled with ore and is opened to put into the lower tank, the under-tank system starts to screen the coke, and the two operations are alternately performed to ensure the screening efficiency.

[0099] In particular, when multiple sintered ore, raw ore, ball ore and coke bins are selected for simultaneous screening, the quality composition of the furnace charge in the multiple bins must meet the quality requirements of the blast furnace smelting.

[0100] By adjusting the size of the screening valve, the screening and transportation time must be less than the time for the furnace charge to enter the blast furnace from the upper tank.

[0101] The technical scheme of the embodiment of the present application first determines the bin to be screened, determines the distance value between the bin to be screened and the next bin to be screened, determines the transportation time difference between the two adjacent bins to be screened in combination with the running speed of the belt, determines the average screening amount of the bin to be screened by using the amount and the total quantity, further corrects the average screening amount by the preset screening flow size in combination with the transportation time difference, determines the discharging time of the bin to be screened by the actual screening speed of the previous bin to be screened and the target screening node quantity. The screening speed is determined by the target screening quantity of the farthest bin to be screened and the preset upper tank time. By reasonably allocating the screening amount and the discharging time of each bin to be screened, the running efficiency of the blast furnace under-tank screening system is improved, and the running time of each bin is reduced by more than 5% compared with the prior art. By reasonably allocating the screening weight and the discharging time node of the bin, the safety risk caused by the stacking of the furnace charge on the belt is eliminated, the belt deviation probability is reduced, and the belt leakage phenomenon is reduced. Under the condition of ensuring the blast furnace charging amount, the screening flow is reasonably controlled to achieve the best screening effect, especially for the raw material with a large amount of powder, the screening quality can be maximized to reduce the powder into the furnace.
