Method and device for increasing bulk density of coal charged into top-charging coke oven

Abstract

The invention relates to a method and a device for increasing the coal charging bulk density of a top-loading coke oven. A plurality of coal charging ports are arranged on the top of the top-loading coke oven, and a coal charging car is used to simultaneously charge coal at the multiple coal charging ports; the coal charging car The coal lowering device is equipped with a telescopic vibration compacting device. When coal is loaded, the vibrating head at the bottom of the telescopic vibration compacting device extends into the position of 1 / 3~2 / 3 of the coal charging height of the coke oven carbonization chamber. Vibration compacts the surrounding coal material; while coal is being loaded, the vibrating head is lifted synchronously with the rise of the coal loading height. After the coal loading is completed, the vibrating head of the telescopic vibration compacting device continues to lift while vibrating, and reaches the top of the coal material Stop the vibration and retract until the stretchable vibrating compact device is withdrawn from the carbonization chamber as a whole. The invention can vibrate and compact the coal charged into the coking chamber of the coke oven, increase the bulk density of the coal charged into the furnace, increase the coal loading and coke output of the single-hole coke oven, and improve the quality of the coke.

Description

technical field [0001] The invention relates to the technical field of coking, in particular to a method and a device for increasing the coal charging bulk density of a top-charging coke oven. Background technique [0002] When coking in a top-loading coke oven, the coal material is usually transported to the top of the carbonization chamber by a coal loading vehicle, and the coal is discharged through multiple coal charging holes on the top of the carbonization chamber with a coal hopper. In this coal charging method, the coal material falls into the carbonization chamber under the action of gravity and accumulates freely. The coal material entering the carbonization chamber is loose and not compact after accumulation, and the closer to the top of the furnace, the lower the bulk density of the coal material, which leads to coking. Poor quality rear top coke. Contents of the invention [0003] The invention provides a method and a device for increasing the coal loading de...
