Solvent mixing device for petroleum asphalt production

The invention discloses a solvent mixing device for petroleum asphalt production, the solvent mixing device comprises a base, the top of the base is provided with a pre-mixing guide mechanism, the pre-mixing guide mechanism comprises a guide groove, a cam rotating roller, a blocking disc, a concave wheel rotating roller and a brush disc, the guide groove is installed at the top of the base, and the cam rotating roller is installed at the bottom of the base. The tops of the two sides of the interior of the guide groove are sleeved with concave wheel rotating rollers. Through a uniform discharging structure during rotation of the discharging mechanism, a solvent is uniformly divided into two groups to be guided into the inner wall of a conical guide plate to slide and be fed, the falling solvent can be subjected to guiding and premixing contact through structural cooperation of a premixing guide mechanism, dispersion of the solvent is further promoted, and through blocking cooperation of two groups of material
