Description

Technical Field

[0002] Fly ash refers to the fine ash collected from the smoke after coal combustion. It is a solid waste after coal combustion, but fly ash can be used as a mixing material for concrete to achieve resource recycling, and the main raw material of fly ash is coal powder.

[0003] At present, coal powder usually relies on temporary storage tanks for storage and transportation during transportation. However, coal powder often condenses in the tank, resulting in the powder being unable to flow freely and adhering to the tank wall. This phenomenon not only makes it difficult for the coal powder to fall smoothly from the tank, but also easily causes wall hanging during transportation, that is, the coal powder condenses on the tank wall to form block-like objects. This brings great trouble to operators because they need to spend a lot of time and energy to clean the tank wall to ensure the smooth transportation of coal powder, which increases transportation costs. Therefore, it is necessary to redesign a fly ash raw material temporary storage tank with the function of preventing raw materials from hanging on the wall to address the above problems.
