For container-type filters, it is required that a coarse wire mesh be placed at the top and a fine wire mesh at the bottom. What is the reasoning behind this?
This context uses the earth as a reference point; it is easier to understand by considering the flow direction of the materials. The coarse mesh should serve as reinforcing ribs for the fine mesh, enhancing the load-bearing capacity per unit area. It is speculated that the materials flow from bottom to top, using the earth as a reference point, for reference only.
It is generally required to cover it with fine wire mesh! ! It’s not common to see requirements for thick wire mesh above
It prevents excessive pressure from breaking the filaments, with the thicker steel wires serving as a protective layer
