Abstract

The invention discloses a lateral tamping device applicable to a large-size coke furnace, which comprises a coal loading device and a coal pushing device of a tamping coal-loading coal-pushing integrated vehicle, a tamping mechanism, a drive unit, a coal hopper, a coal cake box and an automatic coal feeding machine. The invention is characterized in that the tamping mechanism is arranged outside a movable side wall on one side of the coal cake box of the tamping coal-loading coal-pushing integrated vehicle; the upper part of the coal cake box is provided with a tamping baffle plate; and the tamping mechanism is driven by the drive unit. The coal powder is pulverized and mixed, enters a coal bunker, and is sent into the coal cake box on the tamping coal-loading coal-pushing integrated vehicle via conveyer belt; the lateral tamping mechanism is started to tamp the coal cake, so that the coal powder is tamped into the coal cake in the coal cake box; and the coal cake in the coal cake box is pushed into the coke furnace. The invention saves the process of the multiple multi-unit tamping devices and linear induction motor tamping machine, simplifies the coke making tamping technique, and enhances the tamping efficiency.

Description

technical field [0001] The invention belongs to the field of coal processing and relates to a coking tamping technology, in particular to a lateral tamping device and a lateral tamping method for a large coke oven. Background technique [0002] With the development of my country's iron and steel industry and the large-scale blast furnace, the demand for coke and quality requirements are also increasing, but high-quality coking coal resources are becoming increasingly scarce. According to the data released by relevant departments, high volatile weakly caking coal accounts for 47% of the production wells, under construction and available for construction of coking coal in China, and 51.4% of the unused coking coal resources. Gas coal in East China and Northeast China accounted for 78% and 71% of the coking coal reserves in the region respectively. In order to mix more high volatile and weakly caking coal into coking, extensive research and development of coal pretreatment tec...
