Description

[0001] APPARATUS FOR COOLING SINTERED ORE [0002]

The present invention relates to a sintered light cooling apparatus, and more particularly, to a sintered light cooling apparatus equipped with a scraper performing a surface smoothing operation of a cooling truck.

In general, a sintering machine is the main equipment of the sintering plant which produces the sintered ore, which is the main material of the blast furnace. A plurality of connected sintered bogies run at a constant speed along the rails. When the empty truck reaches the light emitter, the upper light stored in the upper light hopper is charged into the truck, laid on the floor, and the blend material is discharged from the surge hopper. The surface of the blend material loaded on the bogie is ignited as the bogie carrying the blend material and the upper light passes through the lower portion by ignition. The sintering process is carried out while the vehicle is driven to the light-splitting part after ignition of the blend material, and the sintered light is sintered in the crusher and then supplied to the cooling device to perform the cooling process.

The sintered-light cooling apparatus is charged into a cooling truck rotated through the light distribution unit, and the air supply unit sucks outside air to supply air to the sintered-light cooling apparatus to cool the sintered light by conduction and convection.

At this time, the cooling drum is sequentially charged with the sintered light and is continuously rotated and rotated along the disk-shaped track rail, and the high temperature sintered light is cooled by the low temperature sintered light and discharged to the destination. One example of such a sintered-crystal cooling apparatus is disclosed in Laid-Open Patent Publication No. 2014-0067607.
