Abstract

The invention relates to a compact type blast furnace material supplying system capable of centrally weighing crude fuel. The compact type blast furnace material supplying system comprises an ore and coke tank, vibrating screens under the tank, scattered weighing hoppers, an ore supplying belt conveyor, a coke supplying belt conveyor, a main feeding belt conveyor, a reversible broken burning belt conveyor, a broken burning belt conveyor, an ore returning belt conveyor, a broken coke belt conveyor and a coke returning belt conveyor, wherein the ore and coke tank mainly comprises a plurality of sintered ore tanks, pellet tanks, lump ore tanks, mixed ore tanks, coke tanks, broken sintered ore tanks and broken coke tanks which are arranged in a two-row parallel manner; one vibrating screen under the tank is arranged under each tank, and one scattered weighing hopper is arranged below each vibrating screen under the tank; and the ore supplying belt conveyor, the coke supplying belt conveyor, the reversible broken burning belt conveyor, the broken burning belt conveyor, the ore returning belt conveyor, the broken coke belt conveyor and the coke returning belt conveyor are all positioned below the scattered weighing hoppers. The system integrates coke tanks, ore tanks, a broken coke screening and recycling system, a broken ore screening and recovering system and the like, so that the occupied area and investments are saved, and high material loading and unloading capabilities are obtained.

Description

technical field [0001] The invention relates to the technical field of blast furnace feeding systems, in particular to a compact blast furnace feeding system in which raw materials and fuels can be weighed centrally. Background technique [0002] The blast furnace feeding system is characterized by a large quantity of transportation and a strong rhythm of work. Its task is to send the pretreated iron ore, coke and auxiliary raw materials from the raw material yard, sintering plant, and coking plant to the blast furnace coke storage tank and ore storage tank by train or belt conveyor. The raw materials mainly include sinter, pellets, lump ore, miscellaneous ore and coke. [0003] At present, there are two technological schemes for the feeding system of blast furnace belt conveyor: one is with centralized weighing hopper, and the other is without centralized weighing hopper. Both options have pros and cons. Among them, the advantage of the scheme with centralized weighing h...
