A high-temperature sintering ore reclaiming method and reclaiming device thereof

Abstract

The invention discloses a high-temperature sinter taking method and a taking device thereof, and relates to a high-temperature sinter waste heat recycling device and method, in particular to a taking method and a taking device thereof, and accordingly, high-temperature sinter can be flexibly switched between a ring cooling / belt cooling technology and a vertical cooling technology. A material taking chute and a material receiving chute are formed in the bottom and the side wall of a hot mine storage bin correspondingly. High-temperature sinter materials slide into the material taking chute preferably. Through the height difference of an inlet of the material receiving chute and an inlet of the material receiving chute, timely switchover of the high-temperature sinter materials between a ring cooling machine and a vertical cooling machine is controlled through inserting-in or pulling-out of a needle-shaped gate valve at the tail end of the material taking chute. The high-temperature sinter taking method and the taking device thereof are used for hot mine taking work of a sinter sensible heat recycling system, operation is simple, safety and convenience are achieved, and running is reliable; and the requirement of the vertical cooling technology for the sinter granularity and heat preservation can be met. The material taking amount can be controlled through the movement speed of a hot mine transferring device while the material heavy load cannot be caused to the hot mine transferring device, and safety and smooth running of the hot mine transferring device can be kept.

Description

technical field [0001] The invention relates to equipment and methods for recovering waste heat from high-temperature sintered ore, and in particular to a material-retrieving method and a material-receiving device that can flexibly switch high-temperature sintered ore between annular cooling / band cooling processes and vertical cooling processes. Background technique [0002] Sinter is the main charge for blast furnace ironmaking in my country, accounting for more than 70% of the iron charge in the furnace. In 2014, the national output of sinter was about 850 million tons. The energy consumption of the sintering process accounts for about 12% of the total energy consumption of iron and steel production (of which the waste heat of sintering waste gas accounts for about 4%, and the sensible heat of sintering ore accounts for about 8%). Thermal resources are the top priority of energy conservation and emission reduction for the entire iron and steel enterprise. [0003] In view...
