Description

Technical Field

[0001] The utility model relates to the technical field of coke oven riser pipes, and more specifically to an emergency device capable of automatically closing and releasing a gas source. Background Art

[0002] With the development of intelligent manufacturing in the country, cylinders have begun to be used in the control system of coke oven risers to replace manual operations for opening and closing the cover of the riser. The realization of mechanized and intelligent operation of coke oven risers has reduced the labor intensity of riser workers, saved the company's labor costs, and improved the company's labor efficiency. However, since the action is controlled by a cylinder, when the 0.4MP--0.6MP gas source is normally supplied to the cylinder, the cylinder will support the riser cover under the action of the gas source, so that the riser cover remains fixed in the open or closed position, which will cause the cylinder to automatically lock the riser cover. Such a situation will cause serious safety hazards in the actual production and operation of the coke oven, especially when the pressure of all the carbonization chambers of the coke oven exceeds 400PA due to a sudden failure or power outage of the chemical product blower, the cylinder of the riser cover of the entire coke oven cannot be automatically opened and depressurized by the carbonization chamber pressure of more than 400PA as before when the cylinder was not pressed because the cylinder is supported by the 0.4--0.6MP gas source. At present, the riser cannot be opened manually on site, and can only be opened remotely and manually one by one on the computer interface to release the pressure when the riser system is not powered off. Due to the sudden failure of the blower to stop or power outage, in an instant, a large amount of waste gas in the carbonization chamber of the coke oven will cause smoke and fire everywhere in the coke oven. There is no time to open the riser covers one by one on the computer interface, and the entire coke oven will immediately fall into a sea of ​​smoke and fire, which will bring serious economic losses and huge environmental risks to the coking plant. Therefore, in order to solve the major safety hazards brought about by the intelligent operation of the riser system, it is urgent to find an emergency device that can instantly close the cylinder gas source and release the cylinder air pressure after the chemical blower suddenly fails or stops or loses power, so that the cylinder of the switch riser can instantly be in a free state without being locked by air pressure. In this way, after the chemical blower suddenly fails or stops or loses power, the riser cover with the cylinder will be automatically opened and released by the carbonization chamber pressure of more than 400PA within a few seconds for pressure relief, and the on-site riser also has the conditions for manual rapid opening and closing, which creates conditions for on-site operators to plan the switch riser according to the pressure conditions of each carbonization chamber. Therefore, for coking plants that plan to implement and have already realized the intelligent and mechanized operation of the riser system, emergency execution devices with high emergency efficiency and good safety and stability have become a major problem that must be solved by each coking plant at this stage.

[0003] Therefore, we propose an emergency device which can automatically shut down and release the gas source to solve the above problems. Utility Model Content

[0037] The pipe nipple 14 includes an air collecting pipe 23, and the air collecting pipe 23 is installed toward the right side;

[0038] A module 18 is provided on the pipe short section 14. The advantage of this arrangement is that the pipe short section 14 is set in a circular shape when in use, so that the gas transported into the interior of 11 can be transported out, and it can also be transported in a circular shape as a whole. In this way, the efficiency of transportation can be improved during transportation. At the same time, 22 installed on the outside of 11 will provide assistance to the transportation efficiency of 14.

[0039] In a further embodiment, a telescopic rod 25 is installed on the outer side of the riser water seal cover 22, the number of the telescopic rods 25 is not less than three, and a telescopic rod 25 is installed on the bottom of the connecting rod 24, and a conveying line 15 is arranged on one side of the telescopic rod 25. The advantage of such a setting is that the height of the switch of the riser water seal cover 22 can be adjusted by the telescopic rod 25 installed at the bottom of the connecting rod 24, and at the same time, the conveying line 15 arranged on one side of the telescopic rod 25 can provide auxiliary positioning for the use of the riser water seal cover 22.

[0040] In a further embodiment, the conveying line 15 includes a normally open electromagnetic control valve 13 and a normally closed electromagnetic control valve 12, and a relay 16 is installed on the outside of the normally closed electromagnetic control valve 12.
