Description

Technical Field

[0001] The utility model relates to the technical field of steel silos, in particular to a homogenizing distributor for steel silos. Background Art

[0002] After the steel silo is loaded with materials, the pile is conical. When the steel silo is discharged, the powdered materials inside leak out from the discharge port. During the leakage process, the material level at the upper end continuously moves downward, and the material level at the upper end of the powdered materials moves downward at different heights. This phenomenon causes a certain part of the pile to suddenly collapse and impact the steel silo. In addition, the uneven material level of the powdered materials causes the internal materials to exert uneven force on the silo wall, causing the silo body to be eccentrically stressed, accelerating the damage of the steel silo. In order to avoid the above problems, the Chinese utility model patent with the prior art publication number CN219314065U proposes a distributor for powdered materials in the steel silo. The distributor can move downward with the material level while the material is discharged, and can also balance the material level at various places by rotating in the steel silo, reducing the height difference at various places, thereby avoiding the problem of powdered materials collapsing in a certain part and impacting the steel silo, and balancing the pressure of the powdered materials on the steel silo.

[0003] However, the above-mentioned distributor only scrapes the top of the material in the steel silo. When cavities appear inside the material due to material compaction or the like, the above-mentioned distributor cannot eliminate the cavities. The collapse of these cavities will cause the material to impact the steel silo, resulting in poor material distribution effect. Utility Model Content
