Description

Technical Field

[0001] The utility model relates to the technical field of asphalt production, in particular to a raw material filtering device for asphalt preparation. Background Art

[0002] Asphalt is a dark brown complex mixture of hydrocarbons of different molecular weights and their non-metallic derivatives. It is a kind of high-viscosity organic liquid, mostly in the form of asphalt or tar. It has a black surface and is soluble in carbon disulfide. When asphalt is processed into modified asphalt in a high-temperature furnace, the asphalt is filtered.

[0003] When filtering existing asphalt raw materials, since there are certain impurities mixed in the asphalt, the filter screen will often be clogged during long-term filtration, which is inconvenient to clear, affecting the efficiency of asphalt raw material filtration. Therefore, we have introduced a new raw material filtration device for asphalt preparation. Utility Model Content
