Description

Float coal pressing device of tamping coke oven side coal charging car

Technical Field

The utility model relates to the technical field of tamping coking equipment, in particular to a coal pressing and floating device of a tamping coke oven side coal charging car.

Background

At present, coke is an important raw material for blast furnace iron making, and is prepared by high-temperature dry distillation of coal in a coke oven, and tamping coking is a coking method in which coal powder in a coal groove of a coal charging car is tamped into a coal cake by using a heavy hammer impact, and then the coal cake is sent into a coking chamber of the coke oven by the coal charging car for high-temperature dry distillation. The coal cake entering the furnace is in a long and thin cuboid structure, the length of the coal cake is about 13-16 m, the width of the coal cake is about 0.45-0.5 m, the tamping principle of heavy hammer impact is limited, a floating coal layer with the thickness of about 0.1m is always remained on the top surface of the tamped coal cake, the density of the floating coal layer is far less than that of the coal cake, and the floating coal layer is in a concave-convex shape due to the non-uniformity of feeding of all the feeders in the length direction of the coal cake, and the height phase difference is about 0.2 m. In the production process of tamping coking, the float coal layer on the top surface of the coal cake as fired causes the following problems: firstly, after the coal cake enters the carbonization chamber, the layer of float coal can float to the top of the carbonization chamber under the action of hot air, and a flue gas channel at the top of the carbonization chamber can be blocked for a long time, so that the quality of coke is influenced; secondly, the float coal can only be changed into coke powder in the carbonization chamber but can not form coke, thereby causing the waste of raw materials; thirdly, in the process that the coal cake enters the carbonization chamber, because of the strong heat radiation of the carbonization chamber, the float coal layer is not completely combusted to generate a large amount of raw coke oven gas, and the raw coke oven gas is dissipated from the open oven door to seriously pollute the environment; fourthly, the layer of float coal is easy to be scattered on the coal charging car, and particularly, when the coal is fed, the scattering of the float coal is aggravated due to the vibration generated when the coal feeding chain is used for transmission.

In order to overcome the adverse effect caused by the floating coal layer, the floating coal layer is stricken and compacted by the tamping coking production process, and the work mainly depends on manual strickle and compaction by a spade at present, so that the labor intensity and the danger of workers are increased, the problems of uneven float coal compaction, poor compaction effect and the like are easily caused, in addition, the working efficiency through manual operation is lower, and the coking requirement cannot be met.

Therefore, the development of the coal pressing and floating device of the tamping coke oven side coal charging car, which has strong adaptability, high automation degree and good scraping and compacting effects, is objectively needed.
