The structure of feed bin among the feeding system in this application not only can be applicable to steelmaking and ironmaking workshop, can also be applicable to the workshop of other material loadings, like mixing proportioning bins, sintering, pelletizing, electric stove, concise, coal injection powder process station, lime kiln etc. its feed bin all can set up weighing sensor. The accurate material type and the accurate material quantity needing to be fed are judged by tracking the reading of the weighing sensor in real time, and the reserve is supplemented by the feeding system in time.

The operation process of the feeding system in the application can be as follows:

the weight of the material in each underground storage bin 11 is read through the first weighing sensor 114, and whether the weight of the material in the underground storage bin 11 meets the feeding requirement of the storage bin in the workshop or not is judged, so that the underground storage bin 11 which does not meet the feeding requirement of the storage bin in the workshop is obtained.

And if the underground storage bin 11 which does not meet the feeding requirement of the storage bin in the workshop is judged to exist, sending information for feeding the underground storage bin 11 which does not meet the feeding requirement of the storage bin in the workshop. At this time, the vehicle transporting the material may be notified to transport the kind and weight of the corresponding material to the underground storage bin system 1. After the vehicle is loaded with the materials, the license plate number and the type of the materials have a corresponding relationship, the control unit sends out the license plate number and corresponding information to the corresponding underground storage bin 11, and a vehicle driver knows the underground storage bin 11 corresponding to self unloading

When the vehicle of transportation material passes through intelligent gate 3, open the corresponding intelligent gate 3 of underground storage bin 11 that does not satisfy the material loading demand of feed bin in the workshop. The storage has the license plate number of the vehicle of transportation material among the control unit, and the license plate number of vehicle is unloaded with own needs underground storage bin has the corresponding relation, and when the vehicle of transportation material was through one of them intelligent gate 3, intelligent gate 3 read the license plate number, and what if the vehicle of transportation material will get into is the corresponding intelligent gate 3 of underground storage bin 11 of the material loading demand of the interior storage bin of unsatisfied workshop, then intelligent gate 3 opens the vehicle that allows the transportation material and unloads through the underground storage bin 11 to the material loading demand of the interior storage bin of unsatisfied workshop. If the vehicle for transporting materials is to enter the intelligent gate 3 corresponding to the underground storage bin 11 meeting the feeding requirement of the storage bin in the workshop, the control unit judges that the vehicle for transporting the materials is to drive into the intelligent gate 3 wrongly through the license plate number of the vehicle and the underground storage bin which needs to unload materials according to the corresponding relation, at the moment, the control unit can control the intelligent gate 3 to be closed and prompt the vehicle for transporting the materials to enter the intelligent gate 3 corresponding to the underground storage bin 11 which does not meet the feeding requirement of the storage bin in the workshop, for example, the intelligent gate 3 can prompt that the vehicle for transporting the materials is to drive into the underground storage bin 11 wrongly and display the correct number of the underground storage bin 11.

After the unloading of the vehicle is completed, the weight of the material in the underground storage bin 11 after the material is replenished is read by the first load cell 114 and sent to the control unit. The control unit updates the weight of the materials in the underground storage bin 11 after supplement in time.

When materials need to be replenished to the steel-making workshop bin 41 in the steel-making workshop bin system 4, the issued operation plan is received at first, and the loading operations are sequenced according to the loading frequency and the loading time priority. The job plan may be made available to the L3 system.

The weight of the material in each of the steelmaking plant bins 41 is read by the second weighing sensor 411, and it is determined whether the weight of the material in the steelmaking plant bin 41 reaches a preset material level, so that the steelmaking plant bin 41 not reaching the preset material level is obtained. In this step, the preset level may be a low level.

If there are steelmaking shop bunkers 41 that do not reach the preset level, the loading schedule of the steelmaking shop bunkers 41 that do not reach the preset level is raised to the highest priority. All the feeding operations are in a queue and are executed from the highest priority to the low priority in sequence until all the feeding operation flows are finished.

When the loading work of the highest priority is started, the position of the first discharging carriage 21 is determined by the first positioning unit 22. The control unit sends an instruction to the first discharging carriage 21 to move the first discharging carriage, and the control unit tracks and knows the position of the first discharging carriage 21 in real time through the first positioning unit 22. The first positioning unit 22 may employ a coded cable positioning system to determine the position of the first tripper car 21 as the first tripper car 21 moves.

When the position of the first discharging carriage 21 reaches the steelmaking workshop bunker 41 with the highest priority in the loading plan, the first feeding machine 115 controlling the corresponding underground bunker 11 in the underground bunker system 1 starts to feed. In the above step, when the position of the first discharge car 21 reaches the steel shop bin 41 of the highest priority in the loading plan, the control unit judges that the position of the first discharge car 21 has arrived through the first positioning unit 22, and then the control unit controls the first discharge car 21 to stop on the belt conveyor 2 above the steel shop bin 41 of the highest priority in the loading plan. Then, the control unit controls the first feeding machine 115 of the corresponding underground silo 11 in the underground silo system 1 to start feeding. The corresponding underground bunker 11 is specifically the underground bunker 11 of the same material type as the highest priority steel plant bunker 41 in the loading plan.

The materials are output to a first unloading vehicle 21 in the steel-making workshop bin system 4 through the belt type conveying mechanism 2, and are unloaded into the steel-making workshop bin 41 with the highest priority in the loading plan through the first unloading vehicle 21.

The weight of the material in the steelmaking plant bin 41 with the highest priority in the feeding plan is read through the second weighing sensor 411, and when the weight of the material in the steelmaking plant bin 41 with the highest priority in the feeding plan meets the requirement, the first feeding machine 115 of the corresponding underground bin 11 in the underground bin system 1 is controlled to stop feeding. For example, when the weight of the material in the steelmaking plant silo 41 with the highest priority in the loading plan reaches a high level, the control unit controls the first feeder 115 of the corresponding underground silo 11 in the underground silo system 1 to stop feeding, and the belt conveyor 2 continues to operate.

After the first feeder 115 controlling the corresponding underground bunker 11 in the underground bunker system 1 stops feeding, the materials already existing on the belt conveyor 2 are continuously output to the first tripper 21 in the steelmaking workshop bunker system 4, and are unloaded into the steelmaking workshop bunker 41 with the highest priority in the feeding plan through the first tripper 21 until the second weighing sensor 411 reads that the weight of the materials in the steelmaking workshop bunker 41 with the highest priority in the feeding plan does not change any more, and then the next feeding operation is started. The first dumper 21 moves to the steelworks bin 41 for the next material type and starts to load the next material.

In the above process, the steelmaking workshop bunker 41 reaching the preset material level may also feed into the converter or the ladle one by one, the second weighing sensor 411 of the corresponding steelmaking workshop bunker 41 weighs the weight of the material in the steelmaking workshop bunker 41 in real time, and when the preset material level is not reached, the feeding plan of the steelmaking workshop bunker 41 not reaching the preset material level is promoted to the highest priority. In this way, when the steel plant bin 41 with the highest priority in the feeding plan is replenished, the steel plant bin 41 reaching the preset level can start the second feeder 412 to feed the converter or the ladle, so that the converter or the ladle can be fed through the steel plant bin system 4 while feeding is performed from the underground bin system 1.

And the MES system of the L3 level issues an operation plan, and the operation plan reaches the L2 level and the L1 level after being decomposed to form a feeding operation queue. According to the weight of materials in an iron-making ore tank, a steel-making high-level bin, a middle-level bin and bins of other systems, the feeding of an underground bin 11 or a stock yard and a storage bin is controlled, if the materials are in emergency shortage, the highest priority of a feeding queue is automatically raised, the feeding is preferentially completed, and the method can complete the feeding operation of various materials according to the queue.

When the materials need to be supplemented to the steelmaking workshop bin 41 in the steelmaking workshop bin system 4, the reduction amount of the materials in the underground bin 11 for supplementing the materials to the steelmaking workshop bin 41 can be obtained through the first weighing sensor 114, the increase amount of the materials in the steelmaking workshop bin 41 for supplementing the materials can be obtained through the second weighing sensor 411, and the natural loss and the actual consumption of the materials can be obtained through statistics based on the reduction amount and the increase amount.

When the materials need to be supplemented to the blast furnace storage bin 51 in the blast furnace ore tank system 5, the assigned operation plan is received, and the loading operation is sequenced according to the loading frequency and the loading time priority. The weight of the material in each blast furnace bunker 51 is read by the third weighing sensor 511, and it is determined whether the weight of the material in the blast furnace bunker 51 reaches the preset material level, so that the blast furnace bunker 51 which does not reach the preset material level is obtained. And the feeding plan of the blast furnace storage bin 51 which does not reach the preset material level is promoted to the highest priority.

When the loading work of the highest priority is started, the position of the second discharging carriage 23 is determined by the second positioning unit 24. When the position of the second discharging car 23 reaches the blast furnace silo 51 with the highest priority in the feeding plan, the first feeding machine 115 controlling the corresponding underground storage silo 11 in the underground storage silo system 1 starts feeding. The material is delivered to the second discharging car 23 in the blast furnace ore tank system 5 through the belt conveyor 2, and is discharged into the blast furnace hopper 51 with the highest priority in the charging plan through the second discharging car 23. The third weighing sensor 511 reads the weight of the material in the blast furnace silo 51 with the highest priority in the loading plan, and when the weight of the material in the blast furnace silo 51 with the highest priority in the loading plan meets the requirement, the first feeder 115 of the corresponding underground storage bin 11 in the underground storage bin system 1 is controlled to stop feeding.

After the first feeding machine 115 controlling the corresponding underground storage bin 11 in the underground storage bin system 1 stops feeding, the materials already existing on the belt type conveying mechanism 2 are continuously output to the second discharging car 23 in the blast furnace ore trough system 5, and are discharged into the blast furnace bin 51 with the highest priority in the feeding plan through the second discharging car 23, until the third weighing sensor 511 reads that the weight of the materials in the blast furnace bin 51 with the highest priority in the feeding plan does not change any more, the next feeding operation is started.

In the above process, the blast furnace silo 51 reaching the preset material level may also sequentially feed the subsequent screening devices, the third weighing sensor 511 of the corresponding blast furnace silo 51 weighs the weight of the material in the blast furnace silo 51 in real time, and when the preset material level is not reached, the feeding plan of the blast furnace silo 51 not reaching the preset material level is raised to the highest priority. In this way, when the blast furnace bunker 51 with the highest priority in the feeding plan is supplemented with material, if the subsequent screening device needs to feed, the blast furnace bunker 51 reaching the preset material level can open the third feeder 512 or the gate 513 to feed the subsequent screening device, so that the feeding from the underground bunker system 1 is realized, and the feeding is performed on the screening device through the blast furnace ore tank system 5.

Similarly, when the blast furnace bunker 51 in the blast furnace ore trough system 5 needs to be supplemented with materials, the reduction amount of the materials in the underground bunker 11 for supplementing the materials to the blast furnace bunker 51 can be obtained through the first weighing sensor 114, the increase amount of the materials in the blast furnace bunker 51 for supplementing the materials can be obtained through the third weighing sensor 511, and the natural loss and the actual consumption of the materials can be obtained through statistics based on the reduction amount and the increase amount.

No matter the steel-making and iron-making workshops or other workshops needing material loading, such as a blending batching tank, a sintering plant, a pelletizing plant, an electric furnace, a refining plant, a coal injection and powder making station, a lime kiln and the like, the material bin can adopt the control process of the material loading system.

This application can be real realize whole unmanned on duty, intelligent operation realizes unmanned participation material loading, greatly reduced workman's intensity of labour. Secondly, the material types and the material amounts of different storage bins needing to be fed can be automatically judged through a weighing sensor, the problem of wrong feeding caused by a manual selection process is avoided, or a material overflow accident is caused by excessive feeding, so that powerful guarantee is provided for long-term stable operation of a feeding system, and compared with the conventional material level meter, the material level meter has the advantages of large error, more faults and incapability of intelligent operation at all; in addition, the intelligent gate 3 with the license plate recognition unit can ensure that vehicles for transporting materials can only enter the corresponding correct underground storage bin 11, so that the problem of material unloading error in the link of only needing personnel to participate is avoided; moreover, the first weighing sensor 114 can accurately track the material quantity of the underground storage bin 11 in real time, so that the material loading vehicle can prepare materials in advance, and the occurrence of material shortage accidents is avoided. Finally, whether spilled materials exist or not can be judged by tracking the feeding amount of the underground storage bin 11 and the feeding amount of the storage bin in the workshop, and the natural loss and the actual consumption of the materials can be counted.
