Description

Technical Field

[0001] The present application relates to the field of automatic control technology, and in particular to an automatic control method and system for dust removal at a tank dumping station. Background Art

[0002] The key to achieving green and environmentally friendly development of steel enterprises is to improve the dust removal effect at the production site. The dust removal pipelines at various points in the steelmaking production, such as the tank dumping station, KR, converter, refining, continuous casting, and ladle preparation, are all connected to the main dust removal pipeline. Therefore, in order to improve the dust removal effect and increase the effective utilization rate of the air volume of the dust removal system, it is necessary to achieve effective control of the dust removal valves at each point, that is, automatically open the dust removal valve when smoke is generated, and automatically close the dust removal valve when smoke is not generated.

[0003] As the first station in a steelmaking plant, the main task of the tank dumping station is to tap iron, that is, to pour the molten iron in the torpedo tank into the iron ladle. During the tapping process, the molten iron is oxidized in contact with the air, generating a large amount of smoke and dust. Therefore, two dust removal devices are installed on the roof of the tank dumping station and the ladle hanging position in the pit. At present, most steel companies rely on manual control for the dust removal system at the tank dumping station, that is, the main control operator manually opens the dust removal valve before tapping iron, and closes the dust removal valve according to the smoke and dust situation after tapping iron. Manual control of the dust removal valve brings two problems. First, the dust removal valve relies on manual control and has a low level of automation. When tapping iron, the operator forgets to open or delays opening the dust removal valve, which can easily cause environmental smoke accidents. Second, the manual closure is not timely, resulting in the dust removal valve being open, resulting in a decrease in the effective utilization rate of the dust removal air volume, which in turn affects the dust removal effect at other points.

[0004] Therefore, it is necessary to propose an automatic control method for dust removal in a tank dumping station to solve the above problems. Summary of the invention

[0005] A series of simplified concepts are introduced in the Summary of the Invention section, which will be further described in detail in the Detailed Description of the Invention section.

[0009] Control the switch state of the dust removal valve at the pit hanging bag position of the tank dumping station according to the judgment result;

[0011] The switch state of the dust removal valve on the roof of the tank dumping station is controlled according to the tipping signal.

[0012] In a feasible implementation manner, the switch state of the dust removal valve at the pit bag hanging position of the tank dumping station is controlled according to the judgment result, including:

[0013] When the judgment result is that the iron ladle contains molten iron, the dust removal valve at the ladle hanging position in the pit of the tank dumping station is controlled to open;

[0014] When the judgment result is that the iron ladle has been lifted away by the overhead crane, the dust removal valve at the ladle lifting position in the pit of the tank dumping station is controlled to be closed.

[0015] In a feasible implementation manner, controlling the switch state of the dust removal valve on the roof of the tank dumping station according to the tipping signal includes:

[0036] In order to better understand the technical solutions provided by the embodiments of this specification, the technical solutions of the embodiments of this specification are described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiments of this specification and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this specification, rather than limitations on the technical solutions of this specification.

[0038] In order to realize automatic control of dust removal at a tank dumping station, improve dust removal effect and effective utilization rate of dust removal air volume, the present application provides an automatic control method for dust removal at a tank dumping station. The method mainly achieves the purpose of automatically controlling the dust removal system of a tank dumping station by associating the control of the dust removal valve at the pit hanging bag position of the tank dumping station with the weighing of the molten iron trolley and associating the control of the dust removal valve on the roof of the tank dumping station with the tipping signal of the torpedo tank.

[0039] See also Figure 1 , which is a schematic flow diagram of an automatic control method for dust removal at a tank dumping station provided in an embodiment of the present application, which may specifically include:

[0040] S110, weighing the iron ladle to determine whether there is excess iron in the iron ladle based on the weighed weight, and obtaining a determination result; wherein, if the weight of the iron ladle is greater than the weight of the empty iron ladle, the determination result is that the iron ladle contains molten iron; if the weight of the iron ladle is less than the weight of the empty iron ladle, the determination result is that the iron ladle has been lifted away by the overhead crane.

[0041] Exemplarily, the ladle is hoisted to the molten iron trolley at the tank pouring station. At this time, the weighing function of the molten iron trolley is used to determine whether there is any remaining molten iron in the ladle. The condition for judgment is to compare the total weight of the current ladle and its internal materials with the weight of the empty ladle. When the weight weighed by the molten iron trolley is greater than the empty ladle weight of the ladle, this indicates that there is still remaining molten iron in the ladle after the iron addition process. When the weight of the molten iron trolley is less than the empty ladle weight of the ladle, it indicates that the ladle has been lifted away by the overhead crane.

[0042] S120. Control the switch state of the dust removal valve at the pit hanging bag position of the tank dumping station according to the judgment result.

[0043] In some examples, controlling the switch state of the dust removal valve at the bag hanging position of the pit of the tank dumping station according to the judgment result includes:

[0044] When the judgment result is that the iron ladle contains molten iron, the dust removal valve at the ladle hanging position in the pit of the tank dumping station is controlled to open;

[0045] When the judgment result is that the iron ladle has been lifted away by the overhead crane, the dust removal valve at the ladle lifting position in the pit of the tank dumping station is controlled to be closed.

[0046] For example, when the weight of the molten iron trolley is greater than the empty ladle weight, it means that there is still residual iron in the ladle after the iron is added. In this case, the dust removal valve at the ladle hanging position in the tank dumping station pit will automatically open. This is because pollutants such as smoke and dust may be generated when there is molten iron, and the dust removal valve needs to be opened for treatment to keep the environment clean. When the weight of the molten iron trolley is less than the empty ladle weight, it indicates that the ladle has been lifted away by the overhead crane. At this time, the dust removal valve at the outlet of the tank dumping station pit is automatically closed because there is no iron ladle generating dust in this area that needs to be treated.

[0047] S130. Update the tipping signal in real time during the process of tipping out the iron; wherein, during the process of tipping out the iron, when the torpedo tank begins to tilt, the tipping signal is triggered as a first trigger signal; when the torpedo tank tilts back to its original position, the tipping signal is triggered as a second trigger signal.

[0048] Exemplarily, when it is determined that the iron ladle contains molten iron and the dust removal valve of the ladle hanging position in the pit of the pouring station is automatically opened, the iron ladle containing molten iron continues to be transported to a specific position specifically used to pour the molten iron from the iron ladle. At this position, wait for the torpedo tank to be aligned, that is, adjust the position of the torpedo tank so that it corresponds to the iron-out position of the iron ladle so as to smoothly receive the molten iron. When all the preparatory work is completed, the operator operates to make the iron ladle begin to tip over and pour the molten iron into the torpedo tank. At this time, the tipping signal changes from 0 to 1 (that is, from the second trigger signal to the first trigger signal), indicating that the iron ladle begins to tip over and tap iron. When the tapping is completed, the tipping signal changes back from 1 to 0 (that is, from the first trigger signal to the second trigger signal), indicating that the iron ladle stops tipping.

[0049] S140. Controlling the switch state of the dust removal valve on the roof of the tank dumping station according to the tipping signal.

[0050] In some examples, controlling the switch state of the dust removal valve on the roof of the tank dumping station according to the tipping signal includes:

[0051] When the tipping signal is the first trigger signal, the dust removal valve on the roof of the tank dumping station is controlled to open;

[0052] When the tipping signal is the second trigger signal, the dust removal valve on the roof of the tank dumping station is controlled to close after a preset delay time.

[0053] Exemplarily, with the start of tipping of iron, that is, when the tipping signal changes from 0 to 1, the dust removal valve on the roof of the tank pouring station automatically opens. When the tipping signal changes from 1 to 0, it indicates that the iron tapping is over. At this time, the dust removal valve on the roof of the tank pouring station will not be closed immediately, but will be automatically closed after a delay of 2 minutes. This is done to ensure that some residual smoke and dust can be completely sucked out after the end of iron tapping. Subsequently, the iron ladle is driven to the ladle lifting position in the pit. During the lifting process of the overhead crane, the weight of the molten iron trolley is less than the empty ladle weight of the iron ladle, which means that the iron ladle has been lifted by the overhead crane. At this time, the dust removal valve at the ladle lifting position in the pit of the tank pouring station is automatically closed. At this point, the fully automatic control of the dust removal system during the iron tapping process is completed. The entire process does not require excessive human intervention. Through the automatic operation of various signals and equipment, efficient and environmentally friendly iron tapping operations are achieved.

[0054] In some examples, it also includes: during the process of tipping out the iron, the dust removal valve at the pit hanging bag position of the tank pouring station and the dust removal valve on the roof of the tank pouring station are both controlled to be in the open state.

[0055] For example, during the iron-out process, it can be determined by signal that the dust removal valve on the roof of the tank dumping station and the dust removal valve at the bag hanging position in the pit of the tank dumping station are both in an open state. In this way, the smoke and dust generated during the iron-out process can be sucked out to prevent the smoke and dust from polluting the environment.

[0056] In summary, the automatic control method for dust removal at the tank pouring station provided in this application can realize fully automatic control of the dust removal process during the iron tapping process of the tank pouring station, avoid environmental smoke accidents caused by human errors in operating the dust removal valve, and improve the automation level of dust removal at the tank pouring station.

[0057] The technical solution of the present application is further described in detail below through specific embodiments.

[0058] The iron-tapping process of the tank dumping station is divided into 6 steps. First, the iron ladle is hoisted to the molten iron trolley of the tank dumping station. The molten iron trolley is weighed to determine whether there is residual iron in the iron ladle. When the weighed weight is greater than the empty weight of the iron ladle, it indicates that there is still residual iron in the iron ladle after the iron is added, and the dust removal valve of the pit hoisting position opens automatically. The iron ladle is opened to the iron-tapping position. After the torpedo tank is aligned, the operator begins to tip the iron out. The tipping signal changes from 0 to 1, and the dust removal valve on the roof of the tank dumping station opens automatically. During the iron-tapping process, the ceiling dust removal valve and the dust removal valve at the ladle hoisting position are both in the open state through signal judgment, and the smoke and dust during the iron-tapping process are sucked out. After the iron-tapping is completed, the tipping signal changes from 1 to 0, and the dust removal valve on the roof of the tank dumping station is automatically closed after a delay of 2 minutes. Subsequently, the iron ladle is opened to the pit hoisting position. During the lifting process of the overhead crane hoisting ladle, the weighing of the molten iron trolley is less than the empty weight of the iron ladle, and the dust removal valve at the pit hoisting position is automatically closed, completing the fully automatic control of dust removal during the iron-tapping process.

[0059] It should be noted that the above embodiments are only the best examples and are not limitations on the implementation methods of the present application.

[0060] Furthermore, the present application also proposes an automatic control system for dust removal at a tank dumping station, which is applied to any of the above-mentioned automatic control methods for dust removal at a tank dumping station, as follows: Figure 2 As shown, this application proposes a functional module schematic diagram of an automatic control system for dust removal at a tank dumping station, including: a molten iron trolley weighing module 21, a dust removal valve control module 22 for a tank dumping station pit hanging bag position, a torpedo tank tipping signal module 23, and a dust removal valve control module 24 for a tank dumping station ceiling, wherein:

[0061] The molten iron trolley weighing module 21 is used to weigh the iron ladle to determine whether there is excess iron in the iron ladle according to the weighed weight, obtain a judgment result, and send the judgment result to the dust removal valve control module of the ladle hanging position in the pit of the tank dumping station;

[0062] The dust removal valve control module 22 of the tank dumping station pit bag hanging position is used to control the switch state of the dust removal valve of the tank dumping station pit bag hanging position according to the judgment result;

[0063] The torpedo tank tipping signal module 23 is used to update the tipping signal in real time during the tipping process, and send the tipping signal to the dust removal valve control module on the roof of the tank dumping station;

[0064] The dust removal valve control module 24 of the tank dumping station ceiling is used to control the switch state of the dust removal valve of the tank dumping station ceiling according to the tipping signal.

[0065] Illustratively, the automatic control system for dust removal at the tank pouring station provided in the present application realizes fully automatic control of the dust removal system during the iron tapping process of the tank pouring station, avoids environmental smoke accidents caused by human errors in operating the dust removal valve, and improves the automation level of dust removal at the tank pouring station.

[0066] In some examples, the dust removal valve control module of the pit hanging ladle position of the tank pouring station is electrically connected to the molten iron trolley weighing module, so that the dust removal valve control module of the pit hanging ladle position of the tank pouring station receives the judgment result sent by the molten iron trolley weighing module, and controls the switch state of the dust removal valve of the pit hanging ladle position of the tank pouring station according to the judgment result;

[0067] The dust removal valve control module on the roof of the tank pouring station is electrically connected to the torpedo tank tipping signal module so that the dust removal valve control module on the roof of the tank pouring station receives the tipping signal sent by the torpedo tank tipping signal module and controls the switching state of the dust removal valve on the roof of the tank pouring station according to the tipping signal.

[0068] Exemplarily, the purpose of automatically controlling the dust removal system of the tank dumping station is achieved by electrically connecting the dust removal valve control module of the pit hanging bag position of the tank dumping station with the molten iron trolley weighing module, and electrically connecting the dust removal valve control module of the roof of the tank dumping station with the torpedo tank tipping signal module.

[0069] In some examples, the molten iron trolley weighing module is also used to weigh the iron ladle to obtain the weight of the iron ladle. If the weight of the iron ladle is greater than the weight of the empty iron ladle, it is judged that the iron ladle contains molten iron; if the weight of the iron ladle is less than the weight of the empty iron ladle, it is judged that the iron ladle has been lifted away by the overhead crane.

[0070] In some examples, the dust removal valve control module of the ladle hanging position in the pit of the tank dumping station is also used to control the dust removal valve of the ladle hanging position in the pit of the tank dumping station to open when the judgment result received is that the ladle contains molten iron; and to control the dust removal valve of the ladle hanging position in the pit of the tank dumping station to close when the judgment result received is that the ladle has been lifted away by the overhead crane.

[0071] Exemplarily, when the dust removal valve control module at the ladle hoisting position in the pit of the tank dumping station is associated with the molten iron trolley weighing module, when the weighing of the molten iron trolley is greater than the empty weight of the ladle (judged that there is molten iron in the ladle), the dust removal valve at the pit outlet of the tank dumping station automatically opens; when the weighing of the molten iron trolley is less than the empty weight of the ladle (judged that the ladle has been lifted away by the overhead crane), the dust removal valve at the pit outlet of the tank dumping station automatically closes.

[0072] In some examples, the torpedo tank tipping signal module is also used to trigger the tipping signal as a first trigger signal when the torpedo tank begins to tilt during the process of tipping out iron; and trigger the tipping signal as a second trigger signal when the torpedo tank tilts back to its original position.

[0073] In some examples, the dust removal valve control module of the tank dumping station ceiling is also used to control the dust removal valve of the tank dumping station ceiling to open when the received tipping signal is the first trigger signal; and to control the dust removal valve of the tank dumping station ceiling to close after a preset delay time when the received tipping signal is the second trigger signal.

[0074] Exemplarily, when the dust removal valve control module on the roof of the tank tipping station is associated with the torpedo tank tipping signal module, when the torpedo tank begins to tilt (the tipping signal is triggered as 1), the dust removal valve on the roof of the tank tipping station automatically opens, and the smoke and dust generated during the iron tapping process are sucked away by the dust removal system; when the torpedo tank tilts back to its original position (the tipping signal is triggered as 0), the dust removal valve on the roof of the tank tipping station automatically closes after a delay of 2 minutes; the above technical solution realizes fully automatic control of the dust removal system of the tank tipping station, thereby avoiding environmental smoke accidents caused by improper operation of the dust removal valve.

[0075] In summary, the automatic control system for dust removal at the tank pouring station provided in the present application realizes full automatic control of the dust removal system of the tank pouring station by associating the dust removal valve control module at the pit outlet of the tank pouring station with the molten iron trolley weighing module, and associating the dust removal valve control module on the ceiling of the tank pouring station with the torpedo tank tipping signal module, thereby improving the effective utilization rate of the dust removal air volume and enhancing the dust removal effect during the iron tapping process.

[0076] The technical solution of the present application is further described in detail below through specific embodiments.

[0077] In one embodiment, during a certain furnace tapping, the ladle is hoisted onto the molten iron trolley at the tank tipping station, and the displayed weighing is 140 tons (the empty ladle weighs 110 tons). Because the weighing is greater than the empty ladle weight, it is judged that there is still excess iron, and the dust removal valve at the ladle hoisting position in the pit of the tank tipping station automatically opens to remove the smoke and dust generated by the excess iron. The molten iron trolley is driven to the tapping position. After the torpedo tank is aligned, the operator begins to tip the tapping, and the tipping signal changes from 0 to 1. The dust removal valve on the roof of the tank tipping station automatically opens. During the tapping process, the dust removal valve on the roof of the tank tipping station and the dust removal valve on the ladle hoisting position in the pit of the tank tipping station are both opened to remove the smoke and dust generated during the tapping process. After the tapping is completed, the tipping signal changes from 1 to 0, and the dust removal valve on the roof of the tank tipping station automatically closes after a delay of 2 minutes. The molten iron trolley is driven to the ladle hoisting position in the pit. During the lifting process of the overhead crane, when the trolley weighs less than the empty ladle weight (110 tons), the dust removal valve on the ladle hoisting position in the pit automatically closes to complete the tapping task.

[0078] In another embodiment, during a certain furnace tapping, the ladle is hoisted onto the molten iron trolley at the tank tipping station, and the display shows that the weighing is 130 tons (the empty ladle weighs 110 tons). Because the weighing is greater than the empty ladle weight, it is judged that there is still excess iron, and the dust removal valve at the ladle hoisting position in the pit of the tank tipping station automatically opens to remove the smoke and dust generated by the excess iron. The molten iron trolley is driven to the tapping position. After the torpedo tank is aligned, the operator begins to tip the tapping, and the tipping signal changes from 0 to 1. The dust removal valve on the roof of the tank tipping station automatically opens. During the tapping process, the dust removal valve on the roof of the tank tipping station and the dust removal valve on the ladle hoisting position in the pit of the tank tipping station are both opened to remove the smoke and dust generated during the tapping process. After the tapping is completed, the tipping signal changes from 1 to 0, and the dust removal valve on the roof of the tank tipping station automatically closes after a delay of 2 minutes. The molten iron trolley is driven to the ladle hoisting position in the pit. During the lifting process of the overhead crane, when the trolley weighs less than the empty ladle weight (110 tons), the dust removal valve on the ladle hoisting position in the pit of the tank tipping station automatically closes to complete the tapping task.
