Abstract

The invention provides a non-blast furnace iron making device feeding system and method. The feeding system comprises a material groove, a material discharge gate, a material belt conveyor under the groove, a vibrating feeder and a vibrating screen, raw materials sequentially pass through the material groove and the material discharge gate and then enter the vibrating feeder, vibration feeding is achieved through the vibrating feeder, therefore, the raw materials are distributed on the vibrating screen, powder materials in the raw materials are screened out through the vibrating screen, the screened raw materials enter a material distributing device on the top of a furnace through the material belt conveyor under the groove, and feeding is achieved. The vibrating screen and the vibrating feeder are introduced, the vibrating screen and the vibrating feeder are used together to screen the raw materials, the vibrating feeder is adopted so that the materials can be loosened, the screening effect is facilitated, and the vibrating screen is used for screening and removing the powder materials from the materials. According to the non-blast furnace iron making device feeding system and method, the content of powder materials entering a vertical reduction furnace is reduced, and the problem that the productivity, the energy consumption and the operability of the whole system are seriously influenced due to the high content of the powder materials in the raw materials in the vertical reduction furnace is solved.

Description

technical field [0001] The invention relates to the field of ironmaking, in particular to a charging system and method for a non-blast furnace ironmaking device. Background technique [0002] The non-blast furnace ironmaking process is called an environmentally friendly green ironmaking process. In the raw material feeding process system used in the non-blast furnace ironmaking equipment that has been put into production at present, there are many powders in the material, which affects the smelting conditions, especially the reduction shaft furnace of the smelting reduction COREX unit, which causes gas due to the high powder content of raw materials. Uneven distribution, poor gas utilization, low metallization rate, easy agglomeration and blockage in the furnace, etc., seriously affect the output, energy consumption and operating rate of the entire system. The problem becomes more prominent after the device is enlarged. [0003] The feeding system of the non-blast furnace ...
