[0039] The terms "first", "second" are only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise stated, the meaning of "a plurality of" is two or more.

[0040] In the description of the present application, it needs to be noted that, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection" should be understood in a broad sense, for example, it can be fixed connection, or detachable connection, or integral connection; it can be directly connected, or indirectly connected through an intermediate medium, or the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0041] The B-type stockyard of the present application mainly uses rail mechanized stacking and reclaiming equipment for operation, and the stacking and reclaiming equipment can operate at the same time in different stockpiles. Two bucket wheel stackers and reclaimers are arranged in the stockyard. Three stock strips (A stock strip, B stock strip and C stock strip) are arranged in the stockyard, each stock strip is 50 meters wide, the widest part of the stacking bottom is up to 37 meters, a plurality of stockpiles are arranged according to different varieties, there is no retaining wall between the stockpiles, the stockpile spacing is 5 meters, and the storage requirements of different materials can be met. Two stacking input lines are arranged in the stockyard, each line is provided with one bucket wheel stacker-reclaimer (stacking and reclaiming in one) and one bucket wheel stacker. Four discharge lines are arranged in the stockyard, which can be respectively supplied to the mixing and proportioning bin, the sintering system, the blast furnace ore bin, the pellet plant and the coal injection plant.

[0042] An implementation method of an intelligent stacking and reclaiming control system of a raw material plant, comprising the following modules:

[0043] 1. Stockyard information module: The stockyard information module is composed of stockyard map information, stock strip and stockpile information, stacker-reclaimer information, belt conveyor information, material basic information and belt path information. Based on the relevant information of the basic properties of the stockyard, raw materials, equipment and process recorded by the stockyard information module, on the basis of fully combing the key process information, research is carried out on the problems such as unloading, stacking and reclaiming decision, stockpile arrangement and process decision in the production scheduling process of the steel enterprise.

[0044] 2. Path decision module: according to the stockpile information, determine the starting point and end point of the material flow, and select the appropriate stockpile path. The selected path needs to meet the following conditions: 1. All belts on the selected flow are in idle state, that is, cannot be occupied by other flows. If all the paths that can be selected have belts occupied, the material continues to wait, and other materials are preferred. 2. The stocker corresponding to the path is idle, that is, it can load the material. 3. If the stocker is idle, it also needs to judge the current state of the reclaimer on the same side and the state of the stocker and reclaimer on the other track. If the reclaimer is in idle state, the path is available, and the distance between the reclaimer and the stockpile position needs to be ensured to be 90 meters. If the distance between the reclaimer and the stockpile position is less than 90 meters, the reclaimer needs to avoid forward. If the reclaimer is working, it needs to judge the relationship between the material to be stacked and the current position of the reclaimer. If the stockpile is 90 meters away from the reclaimer and behind the reclaimer, the material can be stacked at this time. The material continues to wait, and other materials are preferred.

[0045] 3. Stocker module: B-type stockyard adopts double-machine common track arrangement form, and one bucket wheel stocker and one bucket wheel reclaimer are arranged on each track, so the anti-collision facilities of the equipment are relatively complex. The stocker can both stack and reclaim materials, and the reclaimer can only reclaim materials. The system includes two tracks, two stockers 301 and 401, and two reclaimers 501 and 601. The stocker 301 can be used for A and B material strips, and the stocker 401 can be used for B and C material strips. The reclaimer 501 can be used for A and B material strips, and the reclaimer 601 can be used for B and C material strips.

[0046] 4. Stocker operation logic: the reclaimer on the same track cannot cross the stocker, and the anti-collision judgment is needed between the equipment on the same track and the adjacent track. The safety distance between the stocker and the reclaimer on the same track is 90 meters. When one of the two devices is working, if the other device is in idle state, it needs to avoid running to 90 meters away to meet the safety distance requirement. If the space of the material strip is insufficient, the device can run to the front end of the warehouse and adjust the direction to prevent collision. If the other device also needs to work, it needs to judge the distance between the working position and the working device. If the safety distance is met, the device can work, otherwise it needs to wait until the running device finishes working.

[0047] When the two devices on the adjacent tracks are working on the B material strip in the middle, the safety distance of 70 meters needs to be met. When one of the two devices is working, if the other device also needs to work, it needs to judge the distance between the working position and the working device. If the safety distance is met, the device can work, otherwise it needs to wait until the running device finishes working.

[0048] 5. The principle of arranging the stockpile position: The purpose of arranging the stockpile position is to ensure the balance of the stacking and reclaiming device operation rate. In order to prevent the failure of the corresponding stacking and reclaiming device on a certain material strip from leading to the inability to perform the stacking and reclaiming operation and affecting the normal continuous performance of the subsequent production process, the bulk raw materials are configured with double systems or triple systems, that is, two material strips or three material strips are arranged with the same material. The stacking position and the material strip are decided according to the existing site size and the quantity of incoming materials of the same batch. When the free space of the same material strip is not enough for the incoming materials of the same batch, the materials need to be stacked separately. Another situation, which is also a common situation of the stockyard stacking, is that the same variety needs to be stacked separately. The same variety of raw materials or the raw materials with close composition are arranged adjacent to each other, and are arranged according to the material supply area. It needs to be noted that as long as the same device can stack and reclaim, the same horizontal position of different material strips is also regarded as adjacent. The three material strips are left with free space to adapt to the change of the incoming materials, and the special variety is configured in a fixed area.

[0049] 6. The logic of forming the stockpile: The stacking position and the stacking shape are determined according to the reserved position of the material strip and the quantity of incoming materials. The small quantity of incoming materials is stacked in a conical shape, and the large quantity of incoming materials is stacked in a long strip shape. According to the 37° stacking angle, the conical stockpile can be stacked to 5000 cubic meters, and more than 5000 cubic meters needs to be stacked in a long strip shape. According to the volume calculation formula:

[0050] When the stockpile is conical:

[0051] V = 1 / 3 * Math.PI * r * r * r * StrictMath.tan(ang);

[0052] When the stockpile is long strip-shaped:

[0053] r = 18.5;

[0054] V = 1 / 3 * Math.PI * r * r * r * StrictMath.tan(ang) + 1 / 2 * r * r * StrictMath.tan(ang) * length

[0055] In the expression, ang = (37 * Math.PI) / 180;

[0056] Therefore, the radius of the stockpile and the length of the stockpile can be calculated according to the quantity of incoming materials.

[0057] 7. The belt transport quantity calculation module: This module is particularly important in the establishment and simulation running of the simulation model. The belt transport quantity calculation can be calculated according to the belt machine load, the belt machine speed and the transfer length. According to the production process of the steel plant:

[0058] The unit material weight of the belt machine = the belt machine load / the belt machine speed;

[0059] Transport weight = transport length * belt unit material weight.

[0060] The specific embodiments of the present application are further illustrated below with reference to the accompanying drawings

[0061] The B-type stockyard of the present application is provided with A, B and C, three stock strips, each with a width of 50 meters. Two bucket wheel stacker-reclaimers are arranged in the stockyard, and two bucket wheel reclaimers are arranged in the stockyard. Two stack input lines are arranged in the stockyard, and one bucket wheel stacker-reclaimer (stacking and reclaiming in one) is arranged on each line.

[0062] A method for implementing an intelligent stacker-reclaimer control system in a raw material plant, characterized in that the method comprises the following steps:

[0063] S1 For materials coming from a car receiving slot, a wharf or other unloading location and having a stacking location in a B-type stockyard, according to the material type, the material quantity, the unloading time parameters and the like, and in combination with the stockpile stacking principle, the unloading and stacking location of the B-type stockyard is designed to determine the storage and stacking location. The stockpile stacking principle is described in detail in the stockpile stacking principle module.

[0064] S2 Starting from the material unloading location and ending at the material storage location, a suitable stacking path is selected through the belt operation flow decision, and all belts on the selected feeding flow are in an idle state, i.e., cannot be occupied by other feeding flows. If all paths capable of feeding are occupied by belts, the material continues to wait and other materials are preferentially stacked and reclaimed.

[0065] S3 After the material selects a suitable stacking path, the corresponding stacker-reclaimer of the path needs to be in an idle state, i.e., capable of feeding the batch of materials. If the stacker-reclaimer is occupied, another flow capable of feeding is determined. If the new flow corresponds to a stacker-reclaimer on another track, it is determined whether the stacker-reclaimer is idle. If both are occupied, the material continues to wait and other materials are preferentially reclaimed. If any stacker-reclaimer is idle, it is determined whether the stacker-reclaimer can complete the reclamation according to the stacker-reclaimer module and the operation logic. If the reclamation capacity is not met, the material continues to wait and other materials are preferentially reclaimed.

[0066] S4 When the material can be smoothly stacked through the execution of steps S1 to S3, the stacker-reclaimer can execute the dispatching command and run to the stacking location. The stacker-reclaimer and the reclaimer on the same track cannot cross each other, and the devices on the same track and the adjacent track need to be judged for anti-collision. The judgment principle is described in detail in the stacker-reclaimer module and the operation logic module.

[0067] S5 after the stacker reclaimer runs to the stockpile position, the belt conveyor starts to transport the material, at this time, all the belt state machines on the path are set to running. The unloading position of the material can determine the first belt, according to the material transport path, the material flow direction and the belt running speed, the time when the material flow runs to the next belt is calculated; according to the load capacity of the belt conveyor, the speed of the belt conveyor and the transfer length, the belt transport material quantity is calculated, and at the same time, according to the material quantity that the stacker reclaimer has transported, the current stackable material volume can be calculated.

[0068] S6 according to the material pile forming logic module, the material pile radius and the material pile length are calculated according to the material quantity.

[0069] S7 after the stacking plan is completed, the material on the belt is emptied, and the belt on the path is released; after the material on the belt is emptied, the occupied stacker reclaimer is released, and the belt conveyor and the stacker reclaimer state are set to idle, and the material stacking of this batch is completed.

[0070] A kind of raw material plant intelligent stacker reclaimer control system implementation method, when taking material, it is characterized in that, including the following steps:

[0071] S1 when user needs to take material, such as mixing and blending blending tank, sintering system, blast furnace ore tank, pellet plant, coal injection plant, etc., send material taking instruction to B-type yard. Instruction information includes user name, material name, material taking quantity, etc.

[0072] S2 when B-type yard receives material taking instruction, check the position of material to be taken in B-type yard. With material storage position as starting point, taking user as terminal, a suitable material taking path is selected through belt running condition flow decision, all the belts on the selected material taking path are in idle state, i.e. cannot be occupied by other processes, if all the paths capable of taking material are occupied by belts, this material continues to wait, and other materials are taken preferentially.

[0073] S3 after a suitable material taking path is decided, at least one of the material taking machine or stacker reclaimer corresponding to the path needs to be in idle state, i.e. capable of taking material for this batch. If all are occupied, a process capable of taking material is decided again; if one is in idle state, whether taking material can be completed at this time is judged according to stacker reclaimer module and running logic. If taking material capacity is not met, this material continues to wait, and other materials are taken preferentially.

[0074] S4 when the material can be smoothly taken through the execution of S1 to S3 steps, the stacker reclaimer executes scheduling command and runs to the stockpile position. The material taking machine on the same track cannot run across the stacker reclaimer, and the devices between the same track and adjacent track need to be judged for anti-collision. The judgment principle is described in detail in the stacker reclaimer module and running logic module.

[0075] S5 after the stacker reclaimer runs to the stockpile position, the belt conveyor starts to transport material, at this time, all the belt state machines on the path are set to run. The first belt can be determined by the storage position of the material. According to the material transport path, the material flow direction and the belt running speed, the material flow running time to the next belt is calculated; the belt transport material quantity is calculated according to the belt conveyor load, the belt conveyor speed and the transfer length, and whether the material taking plan is completed is determined according to the material quantity transported by the stacker reclaimer.

[0076] S6 after the material taking plan is completed, the material on the belt is emptied, and the belt on the path is released; after the material on the belt is emptied, the occupied stacker reclaimer is released, and the state of the belt conveyor and the stacker reclaimer is set to idle, and the material taking of this batch is completed.
