Description

Technical Field

[0001] The embodiments of the present invention relate to automatic control technology, and in particular to a water quenching control method, device and system. Background Art

[0002] When the carbonization chamber of the coke oven reaches the coking time, the coke pusher pushes the high-temperature red coke inside the carbonization chamber onto the coke quenching car. After the coke quenching car is loaded with the high-temperature coke, it is driven into the coke quenching tower for water-cooling of the coke. After waiting for the coke to be cooled by water, the coke quenching car is driven into the coke drying platform and the cooled coke is placed into the coke drying platform.

[0003] After the coke is placed in the coke drying platform, a scraper is needed to collect the coke. The existing scraper uses manual scrapers to transport the coke to the coke bin for storage. After the water-quenched coke truck places the cold coke on the coke drying platform, the scraper is manually started to transport the coke to the coke bin for storage. This not only affects the cooling time of the truck, but also wastes manpower to start the scraper equipment on site all the time.

[0004] Furthermore, the quenching car relies on manual operation, requiring manual inspection of the car's position to determine which coke drying platform to place the cooling coke on. This manual alignment often results in coke spilling onto the ground, leading to accidents. Manual operation of the scraper also requires synchronization with the quenching car's travel time. Failure to do so can also result in coke spilling onto the ground, leading to accidents.

[0005] In summary, the coke quenching vehicle driver and the coke drying platform operator must have a very tacit understanding of their operating methods, the operators must be very serious and not be distracted, and the overall coke quenching system has a low degree of automation.

[0040] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It will be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all structures.

[0041] Example 1

[0042] This embodiment provides a water quenching control method, which can be configured to be executed by a PLC (Programmable Logic Controller). The PLC can be configured on a water quenching car and connected to designated actuators on the water quenching car to achieve control of the aforementioned actuators.

[0043] Figure 1 This is a flow chart of the water quenching control method in the embodiment, refer to Figure 1 , water quenching control methods include:

[0044] S101. Determine whether the coke quenching car has reached the coke drying station. When the coke quenching car has reached the coke drying station, generate a first coke tank transmission bearing control instruction.

[0045] In this embodiment, the coke drying station is used to dry and cool the coke, so that the coke reaches a dry state after being cooled by water quenching.

[0046] There may be multiple coke drying stations, which may be arranged continuously or at intervals. At the same time, each coke drying station may be positioned separately.

[0047] In this embodiment, the method for determining whether the quenching car has reached the coke drying position is not limited. For example, the method for determining whether the quenching car has reached the coke drying position may be:

[0048] Read the track position code of the quenching car's running track. If the track position code is the specified code, it is determined that the quenching car has reached the coke drying station;

[0049] Alternatively, the quenching car is positioned. If the spatial position of the quenching car is consistent with the spatial coordinates of the preset coke drying station (for example, the horizontal coordinates or vertical coordinates of the two are the same), it is determined that the quenching car has reached the coke drying station.

[0050] In this embodiment, the coke tank transmission bearing is arranged on the coke tank gate of the coke quenching car. When the coke tank transmission bearing rotates, the coke tank gate can be opened or closed. When the coke tank gate is opened, the water-quenched coke in the coke tank can be discharged outward.

[0051] In this embodiment, the first coke tank transmission bearing control instruction is used to control the coke tank transmission bearing to move in the forward direction, thereby driving the coke tank gate to open.

[0052] S102. Determine whether the coke tank transmission bearing has rotated to the maximum switch position. When the maximum switch position is reached, determine whether a scraper start signal is received.

[0053] In this embodiment, the method for determining whether the coke tank transmission bearing has rotated to the maximum switch position is not limited;

[0054] For example, a proximity switch can be set at the coke tank gate. When the coke tank gate moves, the detection signal of the proximity switch is used to determine whether the coke tank transmission bearing has moved to the maximum switch position.

[0055] Alternatively, an encoder may be provided at the coke tank transmission bearing. When the coke tank transmission bearing rotates, the detection signal of the encoder is used to determine whether the coke tank transmission bearing has moved to the maximum switch position.

[0056] In this embodiment, the scraper start signal is set to be issued by a designated controller (such as a scraper controller, etc.), which is set in an operating room (the spatial location of the operating room is unrelated to the water quenching car and is not on the water quenching car) and is connected to the PLC configured on the water quenching car for communication.

[0057] S103. After receiving the scraper start signal, after a set time period, a second coke tank drive shaft control instruction is generated.

[0058] In this embodiment, the second coke tank transmission bearing control instruction is used to control the coke tank transmission bearing to move in the reverse direction, thereby driving the coke tank gate to close.

[0059] In this embodiment, after receiving the scraper start signal, the water quenching car stops at the current coke drying platform before the time reaches the set duration, and the coke tank gate remains open.

[0060] In this embodiment, if the scraper start signal is not received within a certain period of time, a second coke tank drive shaft control instruction is generated, and at the same time, a scraper fault prompt instruction is generated.

[0061] Illustratively, in this embodiment, the set time is set based on experience or actual needs, and the set time is used to allow the water-quenched coke discharged from the coke tank of the water-quenching coke truck to fill the coke drying platform.

[0062] S104. Determine whether the coke tank transmission bearing has rotated to the minimum switch position. When the minimum switch position is reached, generate a quenching car travel control instruction to control the quenching car to move to the next coke drying station.

[0063] Based on the content recorded in step S102, in this embodiment, whether the coke tank transmission bearing moves to the minimum switch position is determined by the detection signal of the proximity switch; or, whether the coke tank transmission bearing moves to the minimum switch position is determined by the detection signal of the encoder.

[0064] This embodiment proposes a water quenching control method, in which a water quenching car automatically determines whether it has reached a coke airing station where cooled coke needs to be placed. After reaching the designated coke airing station, when the coke pot transmission bearing rotates to the maximum switch position, instruction information is generated, and the instruction information is set as one of the bases for allowing the scraper to start, thereby realizing automatic linkage between the movement of the water quenching car and the start of the scraper. When the scraper start signal is received, after the coke pot transmission bearing rotates to the minimum switch position, a quenching car movement control instruction is generated to control the quenching car to move to the next coke airing station, thereby realizing automatic control of the water quenching system.

[0065] exist Figure 1 Based on the scheme shown, in one possible implementation scheme, the water quenching control method further includes:

[0066] Determine whether the coke drying platform cooling coke emptying signal is received;

[0067] If the quenching car arrives at the coke drying platform and receives the coke drying platform cooling coke emptying signal, a first coke tank drive shaft control instruction is generated.

[0068] Exemplarily, in this solution, the cooling coke emptying signal of the coke drying platform is set to be sent by the controller, and the cooling coke emptying signal of the coke drying platform is set to indicate that the water-quenched coke in the coke drying platform is emptied (by a scraper).

[0069] For example, in this solution, the controller is configured to determine whether the water-quenched coke in the coke drying station is emptied, and then generate a coke drying station cooling coke emptying signal;

[0070] There is no limitation on the method for the controller to determine whether the water-quenched coke in the coke airing station is emptied. For example, an infrared sensor, an ultrasonic sensor, etc. can be configured in the coke airing station.

[0071] Based on the difference in detection signals of the above-mentioned sensor when the water-quenched coke is emptied and when it is not emptied, the controller can be configured to determine whether the water-quenched coke in the coke airing station is emptied through the detection signal of the above-mentioned sensor.

[0072] Exemplarily, in this solution, if the quenching car arrives at the coke airing station and does not receive the coke airing station cooled coke emptying signal, a quenching car travel control instruction is generated to control the quenching car to travel to the next coke airing station.

[0073] exist Figure 1 On the basis of the scheme shown, in one possible implementation scheme, after receiving the scraper start signal, it also includes:

[0074] Wait for the signal that the cooling coke on the coke drying platform is empty;

[0075] After receiving the scraper conveyor stop signal and the coke drying platform cooling coke emptying signal, the second coke tank drive shaft control instruction is generated.

[0076] In this solution, the cooling coke emptying signal of the coke drying platform is set to be sent by the controller, and the cooling coke emptying signal of the coke drying platform is set to instruct the water-quenched coke in the coke drying platform to be emptied (by a scraper).

[0077] For example, in this solution, the controller is configured to determine whether the water-quenched coke in the coke drying station is emptied, and then generate a coke drying station cooling coke emptying signal;

[0078] There is no limitation on the method for the controller to determine whether the water-quenched coke in the coke airing station is emptied. For example, an infrared sensor, an ultrasonic sensor, etc. can be configured in the coke airing station.

[0079] Based on the difference in detection signals of the above-mentioned sensor when the water-quenched coke is emptied and when it is not emptied, the controller can be configured to determine whether the water-quenched coke in the coke airing station is emptied through the detection signal of the above-mentioned sensor.

[0080] exist Figure 1 Based on the scheme shown, in one possible implementation method, determining whether the coke quenching car has reached the coke airing station includes:

[0081] Obtain the track code and determine whether the quenching car has reached the coke drying station based on the track code.

[0082] In this solution, the running track of the water quenching car is configured with a coding cable, and the PLC is set to obtain the track code through the coding cable, and then determine the running position of the water quenching car through the track code, that is, determine whether the (water) quenching car has reached the coke drying station.

[0083] exist Figure 1 On the basis of the scheme shown, in one possible implementation scheme, a plurality of air-drying stations are set, and one air-drying station corresponds to one scraper machine start signal.

[0084] For example, in this solution, one scraper machine is configured for each coke drying station, and the scraper machines configured for multiple coke drying stations are all controlled by the same controller.

[0085] For example, in this solution, the water quenching control method is described by including three coke airing stations:

[0086] Determine whether the quenching car has reached the first coke drying station. When it reaches the first coke drying station, generate the first coke tank transmission bearing control instruction;

[0087] Determine whether the coke tank transmission bearing has rotated to the maximum switch position. When the maximum switch position is reached, determine whether the first scraper start signal has been received.

[0088] After receiving the start signal of the first scraper, after the set time, the second coke tank transmission shaft control instruction is generated;

[0089] Determine whether the coke tank transmission bearing has rotated to the minimum switch position. When the minimum switch position is reached, generate a quenching car travel control instruction to control the quenching car to move to the second coke drying station;

[0091] Determine whether the coke tank transmission bearing has rotated to the maximum switch position. When the maximum switch position is reached, determine whether the second scraper start signal has been received.

[0092] After receiving the start signal of the first scraper, after the set time, the second coke tank transmission shaft control instruction is generated;

[0093] Determine whether the coke tank transmission bearing has rotated to the minimum switch position. When the minimum switch position is reached, generate a quenching car travel control instruction to control the quenching car to move to the third coke drying station;

[0099] Obtain the quenching car door sensor signal and determine whether the coke tank transmission bearing has rotated to the maximum switch position or the minimum switch position based on the quenching car door sensor information.

[0100] For example, in this solution, a proximity switch is set at the coke tank gate. When the coke tank gate moves, the detection signal of the proximity switch is used to determine whether the coke tank transmission bearing moves to the maximum switch position or the minimum switch position.

[0101] exist Figure 1 On the basis of the scheme shown, in one possible implementation scheme, the scraper start signal is set as a wireless communication signal; accordingly, the PLC is configured to be connected to the controller for wireless communication.

[0102] In this embodiment, the solutions corresponding to any of the above water quenching control methods can be freely arranged and combined. Figure 2 This is another flow chart of the water quenching control method in the embodiment, refer to Figure 2 In one embodiment, the water quenching control method includes:

[0115] In this embodiment, the water quenching control unit can be configured to implement any one of the water quenching control methods described in Example 1. The implementation process and beneficial effects are the same as those described in Example 1 and are not described again here.

[0116] Example 3

[0117] This embodiment provides a water quenching control system, which is equipped with a vehicle-mounted controller. The vehicle-mounted controller is equipped with an executable program. When the executable program is run, any one of the water quenching control methods described in the first embodiment is implemented.

[0118] Illustratively, in this embodiment, the vehicle controller may adopt a PLC, which may include a PLC master station and one or more PLC slave stations.

[0119] Furthermore, the water quenching control system further includes a first communication module, a second communication module, and an operation room controller;

[0120] The vehicle-mounted controller is connected to the first communication module, and the operating room controller is connected to the second communication module;

[0121] The first communication module is wirelessly connected to the second communication module;

[0122] The operation room controller is configured to control the operation of the scraper, generate and output a scraper start signal and a scraper stop signal.

[0123] Illustratively, in this embodiment, the PLC is wirelessly connected to the controller during operation, and the PLC receives the scraper start signal through the first communication module and the second communication module.

[0124] For example, in this embodiment, there may be multiple coke drying stations, and one coke drying station is configured with one scraper. Accordingly, one coke drying station is corresponding to one scraper start signal.

[0125] The scraper machines equipped with multiple drying stations are all connected to the operation room controller and are controlled by the same operation room controller.

[0126] Furthermore, the water quenching control system further includes an infrared sensor, which is arranged at the coke outlet of the coke drying station;

[0127] The infrared sensor is communicatively connected with the operation room controller;

[0128] The operating room controller is configured to generate a scraper start signal or a scraper stop signal according to the measurement signal of the infrared sensor.

[0129] For example, in this solution, the infrared sensor generates different detection signals when the water-quenched coke is emptied and when it is not emptied, and the operating room controller is configured to determine whether the water-quenched coke in the coke airing station is emptied based on the difference in the detection signals;

[0130] When the controller determines that the water-quenched coke in the coke airing station is emptied during operation, it generates a scraper stop signal (for the scraper corresponding to the coke airing station).

[0131] Figure 3 is a schematic diagram of the PLC in the embodiment, Figure 4 This is a schematic diagram of the quenching door sensor switch in the embodiment. Figure 5 This is a schematic diagram of the water quenching control system in the embodiment, refer to Figures 3 to 5 In one embodiment, the water quenching control system includes:

[0132] A PLC controller 101, an address detection unit 102, and an onboard controller 103, wherein the onboard controller 103 is connected to the PLC controller 101 and the address detection unit 102 respectively;

[0133] The PLC controller 101, the address detection unit 102, and the vehicle controller 103 are respectively configured on the water quenching vehicle;

[0134] The water quenching vehicle is also equipped with a first communication module 601, which is connected to the vehicle controller 103;

[0135] The coke tank gate 201 of the water quenching vehicle is also equipped with a quenching door sensor switch 202, which is connected to the vehicle controller 103;

[0136] The water quenching car is assumed to be running on a track, on which a coding cable 700 is provided;

[0137] It also includes an operating room controller 800 and a second communication module 602, wherein the second communication module 602 is connected to the operating room controller 800;

[0138] The first communication module 601 is connected to the second communication module 602 via wireless communication;

[0139] The coke outlet of the drying station 1000 is also equipped with a scraper 500, a first infrared sensor 401, and a second infrared sensor 402;

[0140] The scraper 500 , the first infrared sensor device 401 , and the second infrared sensor device 402 are respectively connected to the operation room controller 800 .

[0141] In this solution, the water quenching car is aligned at the designated location, and the PLC controller 101 is configured to collect the code of the coding cable, and then accurately determine whether the water quenching car has traveled to the designated location based on the code;

[0142] In this solution, a PLC controller 101, an address detection unit 102, and an onboard controller 103 are configured to form a communication system on a water quenching coke vehicle, wherein the PLC controller 101 is mainly configured to collect analog and digital quantities;

[0143] The data related to the coding cable used by the PLC controller 101 is transmitted to the address detection unit 102 for analysis. The data analyzed by the address detection unit 102 can be fed back to the display screen of the vehicle controller 103 for display;

[0144] The displayed information of the vehicle controller 103 means: "C" represents communication, "-" represents address, "P" represents PLC, and the number "168.13" below is the address code (the code of a specified position of the coding cable), which will change as long as the water-quenching coke vehicle moves.

[0145] In this solution, the address code is set to correspond to the vehicle alignment signal of the water quenching car, and the vehicle alignment signal is set to correspond to the door opening and closing signals of the coke drum (of the water quenching car);

[0146] In this solution, the quenching door sensor switch 202 moves with the rotation of the coke tank gate 201 of the water quenching vehicle. When the coke tank gate 201 is fully opened, the quenching door sensor switch 202 generates an induction control switch signal and feeds the signal back to the PLC controller 101.

[0147] In this solution, the induction control switch signal is set as one of the bases for starting the scraper 500. When the coke tank gate 201 is fully opened, the PLC controller 101 wirelessly sends an instruction to the operation room controller 800 (via the first communication module 601 and the second communication module 602) to allow the scraper 500 to start.

[0148] In this solution, the coke tank gate 201 of the vehicle coke tank is set to be driven by the vehicle air compressor, and the coke tank gate 201 is pushed open by the air pressure of the air compressor.

[0149] In this solution, the first infrared sensor device 401 is configured to transmit infrared signals, and the second infrared sensor device 402 is configured to receive infrared signals. When the first infrared sensor device 401 is activated, it emits a beam of infrared light. If there is an obstruction between the first infrared sensor device 401 and the second infrared sensor device 402, the second infrared sensor device 402 will not receive the infrared signal. Otherwise, the second infrared sensor device 402 will continue to receive the infrared signal.

[0150] In this solution, the operating room controller 800 is configured to determine whether the second infrared sensor 402 receives an infrared signal. If it is determined that the second infrared sensor 402 does not receive an infrared signal, the operating room controller 800 will give the scraper 500 a start-up signal to automatically scrape the scraper.

[0151] When the cooled coke in the coke drying station 1000 is emptied, the second infrared sensor 402 can receive the infrared signal. After the operating room controller 800 determines that the second infrared sensor 402 has received the infrared signal, it gives the scraper 500 a stop signal.

[0152] In this solution, when the scraper 500 is running, the operating room controller 800 controls the motor of the scraper 500 to rotate and drive the scraping plate to move forward and backward. At the same time, the operating room controller 800 controls the coke outlet to open when the scraping plate moves forward, and closes the coke outlet when the scraping plate moves back into place.

[0153] In this scheme, after receiving the red coke, the (water) quenching car drives to the coke quenching tower to cool the coke. Then, the quenching car drives to the coke drying area and places the water-quenched coke in the coke drying area from No. 1 to No. 3 in the order of the coke drying area.

[0154] When the quenching car arrives at the first coke drying station (1000), the PLC controller 101 reads the address code of the coding cable, and the address detection unit 102 determines that the address code is the 1# coke drying station. At this time, the on-board controller 103 generates a "quenching car alignment signal" to prove that the car has aligned with the first coke drying station;

[0155] Subsequently, the onboard controller 103 controls the coke drum gate 201 to open. When the coke drum gate 201 opens to the specified position, the onboard controller 103 generates a "quenching car door opening signal" and sends the "quenching car door opening signal" to the control room controller 800 via wireless communication.

[0156] After the operating room controller 800 reads the "quenching car door open signal", if it determines that the second infrared sensor 402 has not received the infrared signal, it controls the scraper 500 to start and remove the coke;

[0157] When the coke is completely removed, the second infrared sensor 402 receives an infrared signal. The control room controller 800 determines that there is no coke in the first coke drying station, and controls the scraper 500 to stop operating.

[0158] After the quenching vehicle discharges a specified amount of water quenching at the first coke drying station (1000), it drives to the first coke drying station and then repeats the above control process except that the relevant content of the first coke drying station is replaced by the second coke drying station.

[0159] In this solution, after the water-quenching vehicle cools the red coke in the cooling tower, it collects data on the address through the four-vehicle interlocking coding cable while moving, and reaches the exact position of the coke drying platform where the cooled coke needs to be placed. When the coke quenching door sensor control switch obtains the door opening signal point, the on-board controller transmits the information to the operation room controller in the coke drying platform operation room through the data wireless network transmitter. The operation room controller starts the corresponding scraper machine. After the scraper machine is started, the scraper machine will continue to run until the cooled coke is placed on the coke drying platform. The operation room controller controls the scraper machine to stop, achieving an automatic cycle effect.
