Description

Technical Field

[0001] The utility model relates to the technical field of rotary kiln cleaning equipment, in particular to an automatic coke cleaning device for a co-current rotary kiln. Background Art

[0002] Under the high-temperature environment of the rotary kiln, some of the materials will be in a molten state. As the rotary kiln rotates, the materials will adhere and coke in large amounts on the inner wall of the rotary kiln near the discharge end. After coking, it affects the height of the tail baffle of the kiln, affects the combustion residence time of the materials in the rotary kiln, affects the thermal loss rate of the materials. Moreover, the coke blocks increase the self-weight of the rotary kiln and reduce the internal space of the rotary kiln.

[0003] However, the current rotary kiln cannot clean the coke during operation. The fallen coke blocks are easy to accumulate at the end of the rotary kiln. And the coke cleaning mainly depends on the natural fall of the coke blocks or the workers entering the inside of the rotary kiln manually with tools after the kiln stops. The coke cleaning environment is harsh and the labor intensity is high. Not only is the efficiency slow, but the coke blocks are easy to injure the operators when falling off. Therefore, an automatic coke cleaning device for a co-current rotary kiln is provided. Summary of the Utility Model

By setting a pushing mechanism and a cleaning component, and cooperating with the rotation of the rotary kiln, the coke blocks on the inner wall of the rotary kiln can be scraped off, which largely avoids manual coke cleaning with tools and reduces the manual labor intensity. By setting a slag guiding component and a slag discharging component, the scraped coke blocks can be collected and cleaned, which is convenient and fast, and avoids the situation of workers being injured by the fallen coke blocks. It overcomes the deficiencies of the prior art and effectively solves the problems that the existing rotary kiln cannot clean the coke during operation, the fallen coke blocks are easy to accumulate at the end of the rotary kiln, and the coke cleaning mainly depends on the natural fall of the coke blocks or the workers entering the inside of the rotary kiln manually with tools after the kiln stops.
