Problems solved by technology
[0003] The preparation and cooling process of sinter is an essential and important process in steel mills. In view of the fact that the traditional process in the metallurgical sintering industry at home and abroad is to use ring coolers as cooling, waste heat recovery has many air leakage points, large air leakage, and low waste heat grade. Incomplete recovery, waste heat recovery efficiency less than 30%, high operating power consumption, high failure rate, frequent and difficult maintenance, restricting efficient recovery and utilization of waste heat from sintering machines. Efficient recovery and utilization of sinter sensible heat is the key to improving energy efficiency in the iron and steel industry Effective Ways

The invention belongs to a charging device of a vertical cooling furnace in the technical field of smelting and sintering, and discloses a bell-less top rotary material distribution device. The bell-less top rotary material distribution device mainly comprises an electric speed reducer, a water-cooled double-pivot transmission mechanism, an air lock cut-off valve, a feed housing and a chute material distributor, wherein the electric speed reducer is used for driving the chute material distributor to perform rotary material distribution through the water-cooled double-pivot transmission mechanism mounted on a cover plate on the feed housing, and the air lock cut-off valve is arranged on a feed port of the feed housing. The bell-less top rotary material distribution device can achieve the purposes of high temperature resistance, wear resistance, smooth feed, uniform material distribution and air lock. The bell-less top rotary material distribution device disclosed by the invention has the advantages of simple structure, reliability in use and convenience in maintenance, and is a main charging device which is indispensable for a furnace mouth in the vertical cooling device. The bell-less top rotary material distribution device can be widely used for rotary material distribution, fixed point material distribution and the like of sintering vertical cooling furnaces and smelting vertical cooling furnaces.
Description
【Technical field】 [0001] Vertical cooling furnace charging equipment belongs to the technical field of smelting and sintering, and relates to a bellless furnace top feeding device, specifically to a charging device that distributes high-temperature materials evenly and reduces air leakage. It is a new type of vertical cooling device that generates electricity efficiently Important equipment essential to the system. 【Background technique】 [0002] The iron and steel industry is a large energy consumer in my country, accounting for about 15% of the total energy consumption in the country. In the process of iron and steel production, the energy consumption of the sintering process ranks second, and the sensible heat of sintering heat in sintering production accounts for more than 40% of the total heat consumption. Efficient recovery and utilization of sinter waste heat and non-ferrous metal smelting waste heat is the most effective way to improve energy conservation and emission...
