Technical Field

[0001] The utility model relates to the technical field of slag micro-powder bins, in particular to a slag micro-powder bin unloading device. Background Art

[0002] Slag powder, whose full name is granulated blast furnace slag powder, is a fine powder made by drying and grinding the waste slag produced when smelting pig iron in steel plants. This kind of powder has the characteristics of small particle size and large surface area, so it has high hydrophilicity and excellent activity. Its hydrophilicity makes concrete and cement mortar mixed with slag powder more likely to produce hydration reaction and form dense cementitious material, thereby improving the impermeability and durability of concrete and mortar.

[0003] In the prior art, during the production and use of slag micropowder, silos are usually used to store a large amount of slag micropowder. Since the slag micropowder particles are fine and easy to agglomerate, the materials discharged from the silo are mixed with agglomerated slag micropowder. The existing micropowder silo unloading device cannot effectively separate the agglomerated slag micropowder from the fine powder, resulting in the overall particle size of the slag micropowder not meeting the standard, affecting the normal use of the slag micropowder. In addition, its own fluidity is poor, and direct discharge may cause problems such as poor material discharge or blockage. Utility Model Content

[0010] Preferably, the outer wall of the transmission shaft B is fixedly sleeved with guide vanes, and the outer wall of the silo is provided with a feed inlet.

[0011] Preferably, a movable baffle is movably connected to the bottom of the silo.

[0012] Preferably, the inner surface wall of the fixed ring sleeve is fixedly connected to the outer surface wall of the silo.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] In the utility model, under the action of the agglomeration screening mechanism, a vibrating screen device is arranged below the silo, and the inclined plate shell and the screen in the vibrating screen device are both in an inclined state.
