TECHNICAL FIELD

[0001] The utility model relates to metallurgical industry coking equipment technical field, concretely is the device of detecting coke tank bottom gate operation state. BACKGROUND

[0002] Dry quenching is a quenching method for extinguishing red coke by inert gas, which has the triple benefits of energy saving, environmental protection and improving coke quality. In recent years, with the increasingly strict environmental protection supervision and the further growth of the domestic dry quenching device market scale, dry quenching device has become one of the key energy-saving promotion projects in China. With the increasingly high requirements of energy saving and environmental protection in the metallurgical industry and the policy guidance of national intelligent manufacturing, dry quenching will continue to develop towards large-scale in the future to meet the demand of coke oven scale and large-scale development. The state attaches great importance to the high-quality development of basic industries. From the projects to be built and reduced in China, it can be seen that large-scale, high efficiency, intelligence and full dry quenching are the inevitable trend of dry quenching development.

[0003] The current mainstream dry quenching system has a blind area of coke tank bottom gate state monitoring. The hoist system and the coke loading system do not have automatic detection of coke clamping function. Coke clamping can only be found when the coke tank ends coke feeding and reaches the standby position or lands on the point of the car. The coke clamping is found late, the time for discovering and processing coke clamping is long, and the efficiency of dry quenching production is low. Therefore, we propose a device for detecting the operation state of the coke tank bottom gate to solve the above problems. CONTENT OF THE UTILITY MODEL

[0030] Embodiment two

[0031] As Figures 3-4 shown, the device for detecting the running state of the coke pot bottom gate according to one embodiment of the utility model further comprises a third vertical plate 18, a second counterweight 19 and a second proximity switch 20.

[0033] In some embodiments, the controller 16, the alarm 17 and the second proximity switch 20 are electrically connected through conductive wires.

[0034] In some embodiments, the balance plate 9 is provided with a rotating shaft, and the rotating shaft is provided with a torsion spring. The surface of the roller 11 is coated with a wear-resistant rubber layer. The torsion spring provides a restoring torque for the balance plate 9. When the bottom gate body 6 collides with the roller 11, the spring drives the balance plate 9 to quickly return to the initial balance position, avoiding false triggering or detection failure caused by mechanical jamming, and ensuring the stability of continuous multiple detections.

[0035] In some embodiments, the first proximity switch 15 and the second proximity switch 20 are photoelectric sensors. In the dry quenching production environment, there are electromagnetic interference sources. The photoelectric sensor is not sensitive to electromagnetic noise, can stably output signals, and reduces the risk of false alarms.

[0036] Working principle or structural principle, in use, in the dry quenching lifting system, the hoist 3 stops lifting when the coke pot body 5 reaches the upper limit of lifting, starts to run, and the coke pot body 5 descends to the loading device after reaching the cooling tower to load coke. After the loading is completed, the hoist 3 lifts the coke pot body 5, and then starts to run again. The detection assembly 1 is arranged at a position 2-3 meters away from the cooling tower 2 meters after the start of the re-running to detect the running state of the bottom gate body 6. During the re-running process after the coke pot body 5 is fully loaded with red coke, if the bottom gate body 6 of the coke pot body 5 does not clamp coke, the bottom gate body 6 is tightly closed and does not tilt downward. During the re-running process, the bottom gate body does not touch the roller 11, so it will not touch the first proximity switch 15 and alarm. The hoist 3 continues to run. During the re-running process after the coke pot body 5 is fully loaded with red coke, if the bottom gate body 6 of the coke pot body 5 clamps coke, the bottom gate body 6 is not tightly closed and tilts downward. During the re-running process, the tilted bottom gate body 6 touches the roller 11, causing the roller 11 to drive the first vertical plate 10 to run downward, and the second vertical plate 12 to run upward and touch the first proximity switch 15. The controller 16 receives the signal to control the alarm 17 to alarm, and the hoist 3 stops running. After receiving the coke clamping signal on site, it is immediately processed, thereby shortening the time to discover coke clamping and improving the work efficiency of the entire dry quenching production. Also, during the re-running process after the coke pot body 5 is fully loaded with red coke, if the bottom gate body 6 of the coke pot body 5 does not clamp coke, the bottom gate body 6 is tightly closed and does not tilt downward. During the re-running process, the bottom gate body 6 does not touch the roller 11, so it will not alarm. The hoist 3 continues to run. During the re-running process after the coke pot body 5 is fully loaded with red coke, if the bottom gate body 6 of the coke pot body 5 clamps coke, the bottom gate body 6 is not tightly closed and tilts downward. During the re-running process, the tilted bottom gate body 6 touches the roller 11, causing the roller 11 to drive the first vertical plate 10 to run downward, and the third vertical plate 18 to run upward and away from the second proximity switch 20. At the same time, the controller 16 receives the information to control the alarm 17 to send an alarm signal, and the hoist 3 stops running.
