Description

Technical Field

[0001] The utility model relates to the technical field of an adjustable coke discharge door for a coke oven, and more specifically to an adjustable coke discharge door for a coke oven. Background Art

[0002] A coke oven is a furnace used to refine coke. Modern coke ovens consist of a carbonization chamber, a combustion chamber, a heat storage chamber, a ramp area, a furnace roof, a foundation, a flue, etc. In the carbonization chamber, the coal is heated in an airtight condition to become coke.

[0003] Coke dry quenching is a technology used to quickly cool high-temperature coke during the coking process. It can effectively improve the quality of coke and reduce the volatile matter and ash content in coke, thereby improving the production efficiency and product quality of the metallurgical industry. At the same time, coke dry quenching technology can also reduce the combustion temperature of coke and reduce environmental pollution, which has an important impact on people's lives and production.

[0004] During the coke oven production process, materials enter and exit mainly through the coke oven feed port and the coke discharge door. In the current prior art, the coke discharge door is designed as a vibrating feeder, which is controlled by a computer. The greater the vibration amplitude, the more coke is discharged.

[0005] The existing adjustable coke discharge door for coke ovens cannot effectively classify and manage the discharged coke, and a large amount of impurities and dust float out during the coke discharge process, polluting the environment.
