A feeding rack 7 is sleeved on the upper surface of the coke oven 11. A combustion furnace 12 is provided on the outer side of the coke oven 11. A gas pipe 15 and a flue pipe 23 are respectively connected through the interior of the combustion furnace 12. A valve body 18 is provided on the outer surface of the gas pipe 15. A switch 16 is provided on one side of the valve body 18. A small motor 17 is connected to the switch 16 through a wire. A detector provided on one side of the switch 16 is connected through the interior of the gas pipe 15. A small motor 17 is fixedly installed on the upper surface of the valve body 18.
[0026] The output shaft of the small motor 17 is rotatably connected to a rotating shaft 19. A ball 20 is fixedly connected to the bottom end of the rotating shaft 19. A connecting block 21 is provided on the outer surface of the ball 20. A baffle plate 22 is fixedly installed on the outer side of the connecting block 21. A pressure regulating valve 24 and a gas flow detection device 26 are respectively installed on the outer side of the flue pipe 23. The gas flow detection device 26 is located directly below the pressure regulating valve 24. A control center 25 is provided on one side of the pressure regulating valve 24 and the gas flow detection device 26. A coke quenching device 29 is installed on the lower surface of the control center 25. A conveyor belt 2 is provided on the upper surface of the operating platform 1. A drive shaft 5 is provided at both ends of the conveyor belt 2. A support base 4 is rotatably installed on the outer side of the drive shaft 5. A conveyor belt 3 is provided directly below the coke discharge trough 14. A drive shaft 6 is provided at both ends of the conveyor belt 3. A support base 28 is rotatably installed on the outer side of the drive shaft 6. The conveyor belt 3 is installed through the coke quenching device 29.
[0027] Specifically, support base 1 4 and support base 2 28 are fixedly installed on the upper surface of the operating platform 1. Drive shaft 1 5 and drive shaft 2 6 are rotatably connected inside support base 1 4 and support base 2 28. Drive shaft 1 5 and drive shaft 2 6 are driven by a motor. The motor and small motor 17 are existing devices; a Y-series AC small motor 17 can be referenced. The working principle of the Y-series AC small motor 17 is existing technology and will not be elaborated here. Drive shaft 1 5 and drive shaft 2 6 drive conveyor belt 1 2 and conveyor belt 2 3 respectively. Support base 1 4 and support base 2 28 provide stable transmission. Coal is conveyed from conveyor belt 1 2 to the feed rack 7. The feed rack 7 is fitted onto the upper surface of the coking furnace 11 and is funnel-shaped to prevent coal from being conveyed into the coking furnace. During the coking process, the coking furnace 11 is fixedly installed on the upper surface of the operating platform 1 by two sets of support legs 27. A movable bearing 10 is movably installed on the upper surface of the coking furnace 11. Inside the movable bearing 10, baffle 8 and baffle 9 are movably installed. When coal falls onto baffle 8 and baffle 9, due to gravity, baffle 8 and baffle 9 tilt downwards, and the coal falls into the coking furnace 11. When no coal is being transported, baffle 8 and baffle 9 are tightly closed. After the coal falls into the coking furnace 11, a combustion furnace 12 is fixedly installed on the outside of the coking furnace 11. A gas pipeline 15 is connected to the outside of the combustion furnace 12, which introduces gas into the coking furnace 11. An igniter 13 is installed on the combustion furnace 12, which ignites the gas, thereby igniting the coal. During the heating process, the coking furnace 11 is heated by supplying gas through the gas pipeline 15. A switch 16 is installed on one side of the gas pipeline 15, fixedly mounted on the upper surface of a support leg 27. A detector on one side of the switch 16 is connected through the gas pipeline 15, allowing for the detection of gas, air, and exhaust gas inside the coking furnace 11. When gas exchange is required, the switch 16 transmits a signal via a wire to start a small motor 17. The small motor 17 is fixedly mounted on the upper surface of the valve body 18. The output shaft of the small motor 17 drives a rotating shaft 19, which in turn drives a ball 20 mounted at its end to rotate. The ball 20 then drives a connecting block 21, which in turn drives two sets of baffles 22 to rotate. The baffle plate 22 is located inside the gas pipeline 15. Driven by the rotating shaft 19, the baffle plate 22 allows for the switching of gas between different combustion chambers or heating channels. This enables automatic switching of the flow direction of gas, air, and exhaust gas via a small motor 17, ensuring a continuous and stable heating process in the coke oven. Simultaneously, it improves the heating uniformity of the coke oven, achieving precise control and increasing coke oven output. A flue pipe 23 is connected to the other side of the coke oven 11. A pressure regulating valve 24 and a gas flow detection device 26, installed outside the flue pipe 23, automatically detect the internal pressure and gas volume of the coke oven 11. The detection results are transmitted to the control center 25 via a second wire. The control center 25 controls the pressure regulating valve 24 and the gas flow detection device 26 via the second wire.Control center 25 automatically adjusts the opening of pressure regulating valve 24 via wire 2 to maintain stable pressure within the system, thereby ensuring that successfully coked coal is discharged from the coke discharge chute 14 installed at the bottom of coking furnace 11. Qualified coke discharged at the bottom is too hot and needs to be cooled. It is then transported to quenching device 29 via conveyor belt 23. The high-temperature successfully coked coal is transferred to quenching device 29 for cooling, which improves coke quality. The working principle of quenching device 29 can be referenced from the quenching method provided in the new environmentally friendly water-cooled nitrogen quenching circulation device in CN206069772U.
[0028] like Figure 2 As shown, the feed rack 7 is funnel-shaped, and one end of the conveyor belt 2 is located directly above the feed rack 7.
[0029] Specifically, coal is conveyed from conveyor belt 2 to feed rack 7, which is fitted onto the upper surface of coking furnace 11. Feed rack 7 is funnel-shaped to prevent coal loss during the process of conveying coal to coking furnace 11.
[0030] like Figure 3 As shown, a movable bearing 10 is movably installed at one end of the coking furnace 11. The outer surface of the movable bearing 10 is provided with a first baffle 8 and a second baffle 9, which are respectively semi-circular.
[0031] Specifically, a movable bearing 10 is movably installed on the upper surface of the coking furnace 11. Inside the movable bearing 10, baffle 1 8 and baffle 2 9 are movably arranged. When coal falls on baffle 1 8 and baffle 2 9, due to gravity, baffle 1 8 and baffle 2 9 flip downwards, and the coal falls into the coking furnace 11. When no coal is being transported, baffle 1 8 and baffle 2 9 are tightly closed.
[0032] like Figure 4 As shown, there are two sets of baffles 22, and the two sets of baffles 22 are located inside the gas pipeline 15.
[0033] Specifically, when gas exchange is required, the exchanger 16 transmits a signal through a wire to start the small motor 17. The small motor 17 is fixedly installed on the upper surface of the valve body 18. The output shaft of the small motor 17 drives the rotating shaft 19 to rotate. The rotating shaft 19 drives the ball 20 installed at the end to rotate. The ball 20 drives the connecting block 21 to rotate. The connecting block 21 drives the two sets of baffles 22 to rotate. The baffles 22 are located inside the gas pipeline 15. By driving the baffles 22 through the rotating shaft 19, the gas can be switched between different combustion chambers or heating channels. Thus, the flow direction of gas, air and exhaust gas can be automatically switched through the small motor 17, so that the heating process of the coke oven can be carried out continuously and stably, ensuring that the gas can be evenly distributed to each heating part and improving the heating uniformity of the coke oven.
[0034] like Figure 3 As shown, the coking furnace 11 has a through hole inside, and the inner wall of the combustion furnace 12 is provided with an igniter 13, which passes through the through hole inside the coking furnace 11.
[0035] Specifically, after the coal falls into the coking furnace 11, a combustion furnace 12 is fixedly installed on the outside of the coking furnace 11. A gas pipeline 15 is connected to the outside of the combustion furnace 12. The gas pipeline 15 inputs the gas into the coking furnace 11. An igniter 13 is installed on the combustion furnace 12. The igniter 13 ignites the gas, thereby heating the coal.
[0036] Working principle: Support base 1 4 and support base 2 28 are fixedly installed on the upper surface of the operating platform 1. Drive shaft 1 5 and drive shaft 2 6 are rotatably connected inside support base 1 4 and support base 2 28. Drive shaft 1 5 and drive shaft 2 6 are driven by a motor. The motor and small motor 17 are existing devices, and Y-series AC small motor 17 can be referenced. The working principle of Y-series AC small motor 17 is existing technology and will not be elaborated in this case. Drive shaft 1 5 and drive shaft 2 6 drive conveyor belt 1 2 and conveyor belt 2 3 respectively. Support base 1 4 and support base 2 28 play a role in stabilizing the transmission. Coal is conveyed from conveyor belt 1 2 to the feed rack 7. The feed rack 7 is sleeved on the upper surface of the coking furnace 11. The feed rack 7 is funnel-shaped to prevent coal from being conveyed to the feed rack. During the coking process, the coking furnace 11 is fixedly installed on the upper surface of the operating platform 1 by two sets of support legs 27. A movable bearing 10 is movably installed on the upper surface of the coking furnace 11. Inside the movable bearing 10, baffle 8 and baffle 9 are movably installed. When coal falls onto baffle 8 and baffle 9, due to gravity, baffle 8 and baffle 9 tilt downwards, and the coal falls into the coking furnace 11. When no coal is being transported, baffle 8 and baffle 9 are tightly closed. After the coal falls into the coking furnace 11, a combustion furnace 12 is fixedly installed on the outside of the coking furnace 11. A gas pipeline 15 is connected to the outside of the combustion furnace 12, which introduces gas into the coking furnace 11. An igniter 13 is installed on the combustion furnace 12, which ignites the gas, thereby igniting the coal. During the heating process, the coking furnace 11 is heated by supplying gas through the gas pipeline 15. A switch 16 is installed on one side of the gas pipeline 15, fixedly mounted on the upper surface of a support leg 27. A detector on one side of the switch 16 is connected through the gas pipeline 15, allowing for the detection of gas, air, and exhaust gas inside the coking furnace 11. When gas exchange is required, the switch 16 transmits a signal via a wire to start a small motor 17. The small motor 17 is fixedly mounted on the upper surface of the valve body 18. The output shaft of the small motor 17 drives a rotating shaft 19, which in turn drives a ball 20 mounted at the end of the shaft. The ball 20 then drives a connecting block 21, which in turn drives two sets of baffles 22. The baffle plate 22 is located inside the gas pipeline 15. Driven by the rotating shaft 19, the baffle plate 22 allows for the switching of gas between different combustion chambers or heating channels. This enables automatic switching of the flow direction of gas, air, and exhaust gas via a small motor 17, ensuring a continuous and stable heating process in the coke oven. Simultaneously, it improves the heating uniformity of the coke oven, achieving precise control and increasing coke oven output. A smoke pipe 23 is connected to the other side of the coke oven 11. A pressure regulating valve 24 and a gas flow detection device 26, installed outside the smoke pipe 23, automatically detect the internal pressure and gas volume of the coke oven 11. The detection results are transmitted to the control center 25 via a second wire. The control center 25 then controls the pressure regulating valve 24 and the gas flow detection device 26 via the second wire.Control center 25 automatically adjusts the opening of pressure regulating valve 24 via wire 2 to maintain stable pressure within the system, thereby ensuring that successfully coked coal is discharged from the coke discharge chute 14 installed at the bottom of coking furnace 11. Qualified coke discharged at the bottom is too hot and needs to be cooled. It is then transported to quenching device 29 via conveyor belt 23. The high-temperature successfully coked coal is transferred to quenching device 29 for cooling, which improves coke quality.
