Description

Technical Field

[0001] The utility model belongs to the technical field of powder arch breaking, and in particular relates to an airflow arch breaking device for a powder silo. Background Art

[0002] Powder silos generally store flowable powders. The powders in the powder silos (such as cement, fly ash, flour, etc.) generally rely on gravity discharge when they are re-discharged. Therefore, the powder silo can be regarded as a conveying equipment under the action of gravity. After searching, the application number "CN202122766657.7" discloses "a powder silo arch breaking device", which records that "the air compressor sprays high-pressure gas from the flow-aiding nozzle through the connecting pipe to help the powder silo to break the arch. The driving mechanism drives the annular gear, thereby driving the annular gear, the annular guide rail, the mounting frame, and the cleaning scraper to rotate in turn. The cleaning scraper is in close contact with the inner wall of the powder silo to clean the bonded powder, improve the arch breaking effect, and ensure the normal operation of the powder silo". Using an air compressor to spray high-pressure gas from the flow-aiding nozzle through the connecting pipe can indeed help the powder silo to break the arch, but there are still the following problems in actual use:

[0003] In actual use, if the material accumulation is too serious and too solid, the efficiency is poor and it is inconvenient to carry and transport.

[0004] Based on this, it is extremely practical to provide a device that can avoid stacking, break arches more efficiently, and is easy to carry and transport. Utility Model Content
