Description

Technical Field

[0001] The utility model relates to the field of storage bin devices, in particular to an anti-blocking and agglomeration powder storage bin. Background Art

[0002] At present, domestic bulk material handling equipment is relatively mature, but the form of silos and their unloading equipment are still relatively simple. The structural form of silos is mostly a straight cylindrical or rectangular structure at the upper end, and a towering inverted cone structure at the lower end, with an overall high height. The unloading method of the storage silo is mostly gravity unloading. Since the lower end of the storage silo is a towering inverted cone, after a period of use, different degrees of blockage will occur. Among them, the powder storage silo with application number "CN201720659408.9" is provided by the utility model. The screen and the feed port are tilted. Fine powder passes through the screen and falls into the storage silo body below the screen, while coarse powder slides to the bottom of the screen and is collected and reused through the pipeline, effectively separating fine powder and coarse powder. The storage silo feeds evenly, and a conical baffle is set at one end close to the discharge port to buffer the powder entering the storage silo body from the feed port to prevent the powder from clogging and agglomerating at the discharge port. However, the silo still has certain shortcomings when in use: due to the long-term accumulation of powder materials inside the silo, the materials located above the silo discharge port are also prone to compaction and blockage. The silo does not have a breaking up structure, making it difficult to discharge materials, and the compacted materials cannot be discharged in time, causing the materials to expire and moldy. Utility Model Content

[0003] The purpose of the utility model is to provide a powder storage silo that is anti-clogging and agglomeration, so as to solve the problem raised in the above background technology that after the powder material inside the silo is accumulated for a long time, the material located above the silo discharge port is also prone to compaction and blockage, and the silo does not have a breaking structure, making it difficult to discharge the material, and the compacted material cannot be discharged in time, causing the material to expire and moldy.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] (1) A fixed plate is installed at the top end of the silo. A speed reducer is installed on the surface of the fixed plate. After the drive motor rotates, it drives the speed reducer to rotate.
