Description

Technical Field

[0001] The utility model relates to the technical field of asphalt production, in particular to a smoke filtering structure for 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, mostly in the form of liquid or semi-solid petroleum. It has a black surface and is soluble in carbon disulfide and carbon tetrachloride. Asphalt is an organic gelling material that is waterproof, moisture-proof and anti-corrosive. During the production process of asphalt, a large amount of smoke will be discharged.

[0003] The patent website announcement number CN 213494292 U discloses an asphalt fume filtration device, including a pipe body, a pipe seat, an inner filter, an outer filter, a pipe connector and a magnet mechanism. When in use, the pipe seat is connected to the exhaust port of the asphalt production equipment through a pipe connection. When the asphalt fume is discharged, it will first be filtered through the inner filter screen for the first time, and then filtered through the outer filter screen for the second time to reduce the dust in the fume. The magnet mechanism can adsorb solid magnetic particles. The structure is simple and practical.

[0004] The applicant believes that the asphalt fume filter device has the following disadvantages: the outer filter and the inner filter are fixed inside the filter device, which leads to the outer filter and the inner filter being easily clogged after long-term use, causing the outer filter and the inner filter to be unable to perform their own filtering functions normally, resulting in defects.
