Coke oven coal leveling bar with pressing device

Abstract

The invention discloses a coke oven coal leveling bar with a pressing device. A plurality of clapboards are fixedly arranged between two side plates; a rolling piece is arranged between two clapboards; the two end shafts of the rolling piece are connected with crank arms and connected with a connecting bar through the crank arms; and a transmission bar is connected with the connecting bar through a rotating shaft and connected with an actuator through a hydraulic bar. The coke oven coal leveling bar has the obvious advantages that the density of a coal cake can be increased, the coke yield of a single oven is increased, and pressing force and pressing depth can be adjusted.

Description

technical field [0001] The invention relates to equipment for coking flat coal in a coke oven, in particular to a coke oven flat coal rod with a pressing device. Background technique [0002] Leveling The coal cone formed during the coal charging process under the coal charging hole of the coke oven carbonization chamber is leveled by the leveling coal rod. While the flat coal rod is leveling the briquettes in the coking chamber of the coke oven, after the coal loading car puts the coal from the coal discharge hole on the top of the coke oven, the pre-leveling is just to flatten the briquettes, and the briquettes formed by the self-falling pressure have a relatively low porosity. big. In the prior art, for the top-loading coke oven feeding coal, the coal is transported to the top of the coal charging hole of the carbonization chamber by the coal loading car, and the coal is discharged from the coal hopper to the coal charging hole on the top of the carbonization chamber, so...

AI Technical Summary

Problems solved by technology

Therefore, the coal loaded into the carbonization chamber is loose and not compact, and the coke produced has a lot of powder coke, the strength of the coke is relatively low, and the quality of the coke is not high.

Such as: the leveling coal rod of the coke oven invented by Publication No. CN13138888A can guarantee a sufficient unimpeded flue in the gas collection chamber at any time during the leveling coal process, and can protect the ideal coal charging rate at the same time, but it cannot solve the problem. The problem of coal seam compaction; another example: a kind of tamping equipment for smelting tamping coke in a top-loading coal coke oven provided by the public number CN2721643Y is to feed the strip-shaped pressure head through the original flat coal rod that can be extended into the carbonization chamber , and make the bar-shaped pressure head tamp (compact) the coal in the carbonization chamber to increase the coke output and quality of the single furnace, but the device has a complex structure and is inconvenient to use
