Feeding system for blast furnace ore and coke channel system

Abstract

The invention relates to a feeding system for a blast furnace ore and coke channel system, belonging to the technical field of the iron making and producing in the metallurgy industry. The feeding system comprises a blast furnace ore and coke channel system and a feeding system; the blast furnace ore and coke channel system comprises a blast furnace ore and coke channel and equipment arranged on the blast furnace ore and coke channel; the feeding system comprises equipment arranged below the blast furnace ore and coke channel and loading equipment; the equipment arranged on the blast furnace ore and coke channel comprises auxiliary equipment and belt conveyor with a storehouse, wherein the auxiliary equipment and the belt conveyor with a storehouse are arranged on the top surface of the blast furnace ore and coke channel, and the belt conveyor with a storehouse is connected with the top surface of the blast furnace ore and coke channel; each equipment arranged below the blast furnace ore and coke channel comprises a feeding port gate, a feeder, a vibrating screen, a weighing can and an unloading gate; the feeding port gate corresponds to the hopper of the blast furnace ore and coke channel and the outlet thereof one by one; the number of the equipment arranged below the blast furnace ore and coke channel, the number of the hoppers of the blast furnace ore and coke channel and the number of the outlets of the hoppers of the blast furnace ore and coke channel are equal and are 2 or 3 or 4 along the width direction; and the equipment arranged below the blast furnace ore and coke channel corresponds to the hoppers blow the body of the blast furnace ore and coke channel and the outlets of the hoppers along the length direction. The feeding system can serve 3 or 4 blast furnaces and can be used in various forms.

Description

technical field [0001] The invention belongs to the metallurgical industry, the technical field of non-blast furnace ironmaking such as blast furnace ironmaking and smelting reduction. In particular, a blast furnace ore and coke tank feeding system is provided, which can serve two or (3-4) blast furnaces, not only suitable for blast furnace ironmaking, but also non-blast furnace ironmaking (such as: smelting reduction), etc. other technical fields. Background technique [0002] Blast furnace ore and coke trough feeding system consists of two parts: ore and coke trough system (including: equipment on the trough and ore and coke trough), feeding device (including: equipment below the trough and feeding equipment). [0003] 1. Mine and coke tank system. The ore and coke tanks are containers used to store the raw materials and fuels required by the blast furnace. The main function of the ore and coke tanks is to meet the requirements of blast furnace production, batching and a...

AI Technical Summary

Problems solved by technology

The feature of this process arrangement is that the height of the top surface of the mine and coke trough is low, and the capacity of the feeding belt conveyor under the trough can be reduced, thereby saving investment; but the material will be broken again during the transfer process at the relay station, and the overall floor area is also small. bigger
