Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of coal equipment, concretely is coking coal cake hammering device. BACKGROUND

[0002] The tamping coking technology is to hammer and tamp the mixed coal into coal cakes in an iron box similar to the carbonization chamber on the side of the coke oven machine, and then push the coal cakes into the carbonization chamber by a coal supporting plate. The hammering and tamping device is one of the important components of the tamping coking system, and its purpose is to throw the tamping hammer up and down to compact the powdery coal in the coal box into coal cakes by the hammering force generated by the free fall of the tamping hammer, so that the coal cakes reach the compactness required by the production process.

[0003] A mobile type split six-hammer tamping machine is disclosed in the patent with the announcement number CN219772037U.
