Example Embodiment

[0024] Example 1

[0025] The technical problem to be solved by the embodiments of the present invention is to provide a feeding and conveying system for a smelting reduction furnace. The method includes three sets of conveying systems, a pulverized coal feeding and conveying system, a quicklime powder feeding and conveying system, and iron ore powder. , Dolomite powder feeding and conveying system. The pulverized coal adopts 4 sets of string tank systems, which are fed through dry coal bins, intermediate tanks, and injection tanks, and fed by a rotary feeder; quicklime powder uses 2 sets of string tank systems, which pass through lime powder bins, intermediate tanks, and injection tanks. Unloading, feed from the rotary feeder, and connect to two nearby pulverized coal injection pipelines; iron ore powder and dolomite powder use 2 sets of series tank systems, through the hot ore bin, intermediate tank, injection tank, and screw feeding The feeder supplies the material, and the m...

Abstract

The invention discloses a feeding conveying system and method for melting reduction furnace. The system comprises a hot ore bin (1), an intermediate tank (2), a blowing tank (3), a spiral feeder (4),a quick lime powder bin (5), a rotary feeder (6), a dry coal bin (7) and a conveying pipeline (8), wherein an outlet of the hot ore bin (1) is connected to the conveying pipeline (8) through the intermediate tank (2), the blowing tank (3) and the spiral feeder (4) in sequence, an outlet of the quick lime powder bin (5) is connected to the conveying pipeline (8) through the intermediate tank (2), the blowing tank (3) and the rotary feeder (6) in sequence, and an outlet of the dry coal bin (7) sequentially passes through the intermediate tank (2), the blowing tank (3) and the rotary feeder (6) so as to be connected to the conveying pipeline (8).

Description

technical field [0001] The invention relates to a dust feeding and conveying system, in particular to a feeding and conveying system and method for a smelting reduction furnace. Background technique [0002] Blast furnace coal injection technology has been widely used in our country, and more and more blast furnaces adopt coal injection technology. my country's blast furnace coal injection technology and technology have developed to a relatively high level. At present, the state requires that coal injection systems must be installed in newly built or reconstructed blast furnaces. At present, only the coal injection system is used in the blast furnace process, but not only the coal injection system but also the ore injection system are required in the smelting reduction furnace. In addition, the entire injection system technology is not perfect, the powder cannot be fed normally, there are problems such as material blockage, unsmooth feeding, wrong powder sequence control, a...
