Description

Technical Field

[0001] The invention relates to the technical field of metallurgical coking, and in particular to a safe and efficient coke oven equipment power failure emergency system and a control method thereof. Background Art

[0002] The coal loading car runs on the top of the top-loading coke oven. Its function is to take coal from the coal tower and load it into the carbonization chamber, which will produce a large amount of raw coal gas. During normal production and coal loading, the raw coal gas will enter the gas collecting pipe through the riser due to the negative pressure suction generated by the high-pressure ammonia water or monotonic system. When the coke oven is out of power, the high-pressure ammonia water or monotonic system stops working, the negative pressure suction will disappear, and the raw coal gas will suddenly burst out from each coal loading hole. Under the high temperature of nearly 1000℃ in the carbonization chamber, the raw coal gas will burn and burn the guide sleeve mechanism, oil cylinder, cable, oil pipe, etc. near the coal loading hole. If it cannot be controlled in time and the coal loading car is removed, it will burn the equipment or even the entire coal loading car over time, causing greater safety accidents and economic losses.

[0003] The patent document with publication number CN206521427U discloses a device for preventing the coal loading car from burning during a power outage. The patent requires the operator to operate the stop valve in the hydraulic station to relieve the pressure in the guide sleeve cylinder circuit, raise the guide sleeve with the counterweight, and then manually close the furnace cover. The coal loading car cannot move. The whole process requires a high degree of operator participation and unmanned automated operation cannot be achieved. Therefore, the patent has low efficiency and low safety factor when the coke oven is out of power, and there are still great risks for personnel and equipment.

[0004] The patent document with publication number CN206188734U discloses an accumulator for a coal loading car. The patent uses an accumulator to retract the coal loading guide sleeve, but the furnace cover needs to be closed manually, and the coal loading car cannot walk away. The whole process requires a high degree of operator participation and unmanned automated operation cannot be achieved. Therefore, the patent has low efficiency and low safety factor when the coke oven is out of power, and there are still great risks for personnel and equipment.

[0005] The above-mentioned prior art "a device for preventing a coal-loading car from burning during a power outage" and "an accumulator for a coal-loading car" have the following disadvantages in actual use:

[0006] 1) Operators need to enter the hydraulic room to operate and retract the guide sleeve. They cannot evacuate to a safe area immediately. If the fire spreads, it will threaten personal safety and easily cause safety accidents.

[0007] 2) After retracting the guide sleeve, the operator still needs to manually close the furnace cover, but the coal loading hole sprays a lot of fire, which makes it impossible for people to get close, and the furnace cover cannot be closed, which not only threatens personal safety but also burns the car, and finally causes greater economic losses.

[0008] 3) After the coal loading car completes the emergency operation of lifting the guide sleeve and closing the furnace cover, it cannot automatically drive away from the flame spraying area of ​​the coal loading hole, which will cause the fire to spread to the equipment.

[0009] 4) The equipment does not have a complete power outage emergency system. The operating personnel are highly involved in the power outage emergency state and are unable to start the emergency system in the first time to automatically complete a series of emergency operations such as closing the gate, lifting the guide sleeve, closing the furnace cover, driving away the trolley, and braking the trolley.

At this time, the hydraulic oil is pressurized by the diesel engine pump group 83 and enters the main pipeline 88 through the emergency pipeline 84 and then reaches the valve station 814. Relying on the power provided by the UPS device 6, according to the program set by the emergency control system 11:

[0063] 1. Open the gate oil cylinder valve group 812, the gate oil cylinder 41 of the grab gate 4 moves to close the gate 42, and stop the coal feeding;

[0064] 2. Open the guide sleeve cylinder valve group 811, and the guide sleeve cylinder 31 of the guide sleeve device 3 moves to lift the movable guide sleeve 32 and separate it from the coal loading hole 17.

[0065] 3. Since the UPS device 6 has supplied power to the electromagnet 26, the furnace cover 16 is ensured not to fall. The horizontal cylinder valve group 89 and the vertical cylinder valve group 810 are opened, and the horizontal cylinder 21 of the lid-lifting device 2 drives the horizontal trolley 23 and simultaneously links the vertical trolley 29 and the lid-lifting trolley 24 to move forward until the electromagnet 26 is concentric with the coal loading hole 17. The vertical cylinder 27 drives the vertical trolley 29 and the lid-lifting trolley 24 to descend together. After the furnace cover 16 is in place, the electromagnet 26 is powered off and disengaged from the furnace cover 16, and the lid-lifting device 2 moves back to the initial position.

[0066] After this step is completed, the emergency control system 11 completes the emergency operations of automatically closing the gate, lifting the guide sleeve, and closing the cover.

[0067] In the second step, the travel transmission device 5 starts emergency operation, and the electromagnetic brake 52 and the electromagnetic clutch 54 are powered by the UPS device 6, respectively, to open the electromagnetic brake 52 and the electromagnetic clutch 54. At this time, the hydraulic motor valve group 813 is opened, and the hydraulic motor 55 in the travel transmission device 5 is started. The hydraulic motor 55 transmits torque to the wheel group 20 through the reducer 51 and the transmission shaft 56, and then drives the entire coal loading car to run slowly to the end platform safety area, away from the fire area, and then the hydraulic motor 55 stops working, and the electromagnetic brake 52 is powered off. At this point, a safe and efficient coke oven equipment power failure emergency system is completed.

[0068] Preferably, the equipment is designed with a complete power outage emergency system and integrated into the PLC system to achieve automated control.

[0069] Preferably, the operating personnel only need to start the power outage emergency system with one button in the driver's cab to evacuate, which is highly safe.

[0070] Preferably, the power outage emergency system can automatically close the gate, which is unmanned and highly efficient.

[0071] Preferably, the power outage emergency system can automatically lift the guide sleeve, which is unmanned and highly efficient.

[0072] Preferably, the power failure emergency system can automatically close the furnace cover and reset the cover-opening device, which is unmanned and highly efficient.

[0074] The present invention is applied to a top-loading coke oven coal-charging car or a ramming coke oven smoke guide car, and can also be used in stock market transformation projects.

[0075] Power outages occasionally occur during coke oven production. If they are not handled properly or in a timely manner, they will cause major safety accidents and major economic losses. Therefore, it is a general trend for coke oven equipment to have "one-button start, safety and efficiency, and unmanned operation" and is a core technology for market competition. The present invention provides a safe and efficient coke oven equipment power outage emergency system and control method, which can enable operators to automatically complete emergency operations such as closing the gate, lifting the guide sleeve, closing the furnace cover, trolley travel, and trolley braking by starting the emergency switch with only one button. It has the characteristics of mechanized operation replacing manual labor, high safety, high efficiency, and high degree of automation, which greatly improves the market competitiveness of the group company's products.
