High-viscosity material front-leading-in conveying device

The utility model relates to a high-viscosity material front-leading-in conveying device which comprises a material conveying barrel, a feeding pipe located at the top of the feeding end of the material conveying barrel, a discharging pipe located at the bottom of the discharging end of the material conveying barrel, and a double-layer spiral blade which is of a cavity type structure. Hot water flows from the feeding end to the discharging end through the cavity in the double-layer spiral blade, materials exchange heat with the double-layer spiral blade in the conveying barrel, and due to thefact that the heat exchange area is limited and the time of the heat exchange process is short, a heat exchange interface can be formed on the contact face of the materials and the double-layer spiralblade in the material conveying process due to the cold and hot temperature difference. The heat exchange interface generates a certain dilution and lubrication effect and is not prone to material adhesion, the fluidity of ma
