Abstract

The invention relates to feeding equipment, in particular to blast-furnace process feeding equipment. The technical problem to be solved is to provide blast-furnace process feeding equipment, to solve the problem, the blast-furnace process feeding equipment is provided. The blast-furnace process feeding equipment comprises a base plate, a heating box, a heating kettle, a vibrating device, a feeding hopper and the like; the vibrating device is arranged at the left end of the top of the base plate, a top supporting frame is arranged above the base plate, a smashing device is arranged on the lower end of the left side of the top supporting frame, the heating box is connected with the lower end of the right side of the top supporting frame, the heating kettle is arranged on the heating box, the feeding hopper is arranged above the left side of the heating kettle, and the feeding hopper is arranged below the smashing device and located above the vibrating device. According to the blast-furnace process feeding equipment, smashing of caked or solid smelting raw materials is achieved, the follow-up heating treatment of the smelting raw materials is accelerated, and meanwhile the vibrated feeding hopper can prevent the smelting raw materials from adhering to the wall of the feeding hopper.

Description

technical field [0001] The invention relates to a feeding device, in particular to a blast furnace smelting feeding device. Background technique [0002] Blast furnace smelting equipment refers to the equipment composed of blast furnace body, blast furnace dust collector, blast furnace blower, blast furnace hot blast stove, molten iron tank car, etc. Due to the good technical and economic indicators of blast furnace ironmaking, simple process, large production volume, high labor production efficiency, and low energy consumption, the iron produced by this method accounts for the vast majority of the world's total iron production. During blast furnace production, iron ore, coke, and flux for slagging are loaded from the top of the furnace, and preheated air is blown in from the tuyeres located at the lower part of the furnace along the periphery of the furnace. At high temperature, the carbon in the coke is burned with the oxygen blown into the air to generate carbon monoxide...
