Coal leveling bar with vibrating compacting function

Abstract

The invention relates to a coal leveling bar with a vibrating compacting function. At least one group of vibrating compacting devices are mounted on the coal leveling bar in the longitudinal direction; each vibrating compacting device comprises a pneumatic vibrator and a compacting plate, and the compacting plate and the coal leveling bar are mounted in the same direction; three hinged supports are longitudinally arranged on each compacting plate, one hinged support is hinged with one end of a connecting rod I, the other end of the connecting rod I is hinged with a piston rod of the corresponding pneumatic vibrator, the other two hinged supports are hinged with one end of a connecting rod II and one end of a connecting rod III respectively, and the other end of the connecting rod II and the other end of the connecting rod III are hinged with the coal leveling bar. The vibrating compacting devices are arranged on the coal leveling bar, the pneumatic vibrators promote the compacting plates to vibrate, a four-bar mechanism promotes the compacting plates to perform vertical patting motions, the purpose of compacting of a coal cake at the top of a top-mounted coking furnace is achieved, the practical use effect is good, the yield of coke of a single furnace is increased, and the coke quality is improved.

Description

technical field [0001] The invention relates to a coal leveling device for a coke pusher, in particular to a leveling coal rod with a vibration compacting function. Background technique [0002] In the prior art, for the top-loaded coke oven, the coal is transported to the top of the coal charging hole in the carbonization chamber by the coal loading car, and the coal is discharged through the coal charging hole on the top of the carbonization chamber by the coal scuttle. When using this method of coal discharge, the coal falls freely into the carbonization chamber through the discharge device. After the coal charging is completed, the top of the coal naturally forms a cone, which needs to be inserted into the furnace from the small square hole on the upper part of the furnace door through a flat coal rod for leveling. . After leveling, a uniform raw gas channel is formed between the coal cake and the furnace roof, and then sealed coking is carried out. However, because th...

AI Technical Summary

Problems solved by technology

However, because the conventional flat coal rod does not have the function of compacting the coal cake, the coal loaded into the carbonization chamber is loose and not compact, and the closer to the top of the furnace, the lower the bulk density of the coal, resulting in poor coke quality at the top
