Description

Technical Field

[0001] The utility model relates to the technical field of asphalt production, in particular to a high-efficiency filtering and impurity-removing device for modified asphalt production. 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. It is in liquid state, with a black surface and is soluble in carbon disulfide. Asphalt is an organic gelling material that is waterproof, moisture-proof and anti-corrosive. Asphalt can be mainly divided into three types: coal tar asphalt, petroleum asphalt and natural asphalt: among them, coal tar asphalt is a by-product of coking. Petroleum asphalt is the residue after crude oil distillation. Natural asphalt is stored underground, some of which form mineral layers or accumulate on the surface of the earth's crust. Asphalt is mainly used in industries such as coatings, plastics, rubber, and paving roads.

After the filter filters out the impurities, the impurities are deposited on the surface of the filter, which can easily clog the filter mesh, causing the filtering effect to gradually deteriorate and the filtering efficiency to decrease. When asphalt is produced, some harmful exhaust gas and dust will be generated, which will be discharged into the air without treatment, affecting the working environment and health of the staff. In view of the above problems, the inventor proposes a high-efficiency filtration and impurity removal device for modified asphalt production to solve the above problems. Utility Model Content
