Convenient-to-adjust proportional distributor for blast furnace smelting

Abstract

The invention provides a convenient-to-adjust proportional distributor for blast furnace smelting, wherein the proportional distributor comprises a storage box, feeding hoppers, an observation window, stirring and conveying frame structures, a mounting frame, a storage battery, side quantitative storage frame structures, redundant material collecting frame structures, a connecting seat, fixing rods, fixing tubes, fixing bolts, a bottom bearing frame structure convenient to disassemble, anti-skid bottom plates and power switches; the feeding hoppers are inserted into the left side and the right side of the upper portion of the storage box; and the stirring and conveying frame structures are mounted on the left side and the right side of the interior of the storage box. Measuring tubes are glued to the lower parts of guide-out tubes, so that the height of a material in the measuring tubes can be conveniently observed by using scale marks according to requirements during use, and the material can be quantitatively guide out during use; and spiral conveying blades are welded to the lower portion of the outer side of each transmission rod, so that the spiral conveying blades can be conveniently driven to rotate through the transmission rods by means of rotating motors during use, and then a material in the storage box can be conveniently guided down from the guide-out tubes.

Description

technical field [0001] The invention belongs to the technical field of blast furnace smelting, and in particular relates to a proportional feeder for blast furnace smelting which is easy to adjust. Background technique [0002] The combination of high alkalinity sinter with acid pellets is currently recognized as an ideal charge structure in the world. With the rapid development of my country's iron and steel industry, the output of iron and steel continues to increase rapidly, and the demand for acid pellets in blast furnaces increases rapidly. Under the condition of high-iron and low-silicon sintering, with the increase of iron grade and decrease of SiO2 content in sinter, the strength of sinter becomes worse and the particle size is smaller. important. In chemical industry, metallurgy, grain, building materials, coal, mining and other bulk material conveying systems, it is often necessary to divert and reload materials. The distributor is a device used for diversion con...
