[0002] Ash is generated during the blast furnace smelting process and is collected by dust collectors. Every year, the steel industry produces a large amount of ash, which requires a huge site to store. If it is not managed properly or not fully utilized, it will not only waste resources but also cause serious pollution.

[0003] Blast furnace dust ash needs to go through ball milling, magnetic separation, flotation, filter pressing, and finally wastewater recovery to separate iron ore concentrate, carbon concentrate, and tailings. In the ball milling process, the blast furnace dust ash needs to fall from the receiving bin to the belt on the belt conveyor, and then be transported to the wet ball mill for ball milling. When the blast furnace dust ash falls to the conveyor and is transported by the conveyor, the impact of the falling blast furnace dust ash will generate large dust, which will pollute the processing area. The blast furnace dust ash is difficult to transport in a relatively sealed state.

[0004] Therefore, a blast furnace dust conveying device is proposed. Utility Model Content

[0025] It should be noted that when the existing blast furnace dust falls onto the conveyor and is transported by the conveyor, the impact of the falling blast furnace dust will generate large dust, which pollutes the processing area. The blast furnace dust is difficult to be transported in a relatively sealed state. The present embodiment can realize the transportation of blast furnace dust in a relatively sealed state through the mutual cooperation of the conveying box 1, the swinging conveying assembly 2 and the conveyor 4, and the swinging feeding of the blast furnace dust receiving bin 26 can not only reduce the impact force of the falling blast furnace dust and reduce the generation of dust, but also avoid the clogging of the blast furnace dust receiving bin 26 causing the feeding to be blocked. By bringing the atomized water droplets into contact with the blast furnace dust, the blast furnace dust can be captured and adsorbed, further reducing dust, and providing a carrier for the subsequent spiral transportation of the blast furnace dust.

[0026] Specifically, in the present embodiment, the scheme mainly includes a swinging material conveying assembly 2. When in use, the blast furnace dust collecting ash is filled into the blast furnace dust collecting receiving bin 26, and the bin cover 3 is closed. When the blast furnace dust collecting ash is conveyed, the electric push rod 23 drives the fixed platform 24 to reciprocate in the horizontal direction through the output end on one side thereof, and under the guidance of the guide slide bar 25, the blast furnace dust collecting receiving bin 26 is made to swing and move. When the blast furnace dust collecting receiving bin 26 moves, the blast furnace dust collecting receiving bin 26 squeezes or stretches the expansion piece 29, and the expansion piece 29 is deformed to ensure the sealing of the through groove 28 to prevent the blast furnace dust collecting ash from leaking out and causing environmental pollution. The blast furnace dust collecting ash in the blast furnace dust collecting receiving bin 26 is discharged to the conveying belt 5 on the conveyor 4 through the inclined discharge plate 27. Under the partition of the rib 6, the conveying belt 5 conveys the blast furnace dust collecting ash, so as to realize the transportation of the blast furnace dust collecting ash in a sealed environment.
