Description

Technical Field

[0001] The utility model relates to the technical field of sintering production, in particular to a sintering fuel crushing device. Background Art

[0002] Sintering is the process of mixing and granulating various iron-containing raw materials, flux (quicklime, limestone, dolomite, magnesite, etc.), fuel (coke powder, coal powder), etc., and then spreading them on a sintering machine for ignition and exhaust sintering. The fuel accounts for a relatively low proportion in the entire sintering ingredients, but plays a vital role in the sintering process. The fuel particle size is an important indicator of sintering production. It is generally required that the proportion of sintering fuel particle size <3mm reaches more than 70%. If the fuel particle size is too coarse, the combustion rate is slow, the combustion zone thickness is widened, and the sintering rate is reduced. If the fuel particle size is too fine, the combustion rate is too fast, the high temperature is maintained for a short time, and the sintered ore output quality is reduced. In addition, too fine fuel may be extracted during the sintering process.

[0003] The existing referenceable Chinese utility model patent with announcement number: CN219377247U discloses a sintering fuel crushing device, which includes a fuel bin, a first vibrating screen, a second vibrating screen, a fuel crusher, a first conveyor belt, a second conveyor belt and a storage tank. The first vibrating screen and the second vibrating screen are respectively arranged below the fuel bin and the fuel crusher; the first vibrating screen is respectively provided with a first conveyor belt and a second conveyor belt at the small particle size and large particle size discharge ends, and the first vibrating screen and the first conveyor belt are sealed; the large particle size discharge end of the second vibrating screen is provided with a storage tank, and the fuel crusher and the second vibrating screen are sealed; dust removal pipes are arranged above the two sealing devices and are connected to the sintering dust removal main pipeline. The above technical scheme can effectively reduce the phenomenon of over-crushing of fuel, while reducing the proportion of large particle size fuel in sintering, improving the sintering production process, and improving the quality of sintered minerals.

[0004] There are cases where the sintering fuel particles are too coarse or too fine, and therefore the fuel particles need to be screened before being crushed in order to achieve the best sintering output and quality. However, the existing sintering fuel crushing device screens the particles, so that some of the particles are stored in the storage box. When the particles in the storage box are transported and used, they are discharged due to accumulation to a certain amount, which makes it easy for particles to be blocked at the outlet, affects the uniformity of feeding, and affects the utilization rate of the sintering fuel and the sintering production process.
