Description

Technical Field

[0001] The utility model belongs to the field of modified asphalt dehydration, in particular to a modified asphalt dehydration device. Background Art

[0002] Modified asphalt, a highly effective plugging material for shale pores and microcracks, is a material with excellent plugging properties achieved through a specific process. This modified asphalt typically incorporates multiple ingredients, such as graphene and bentonite, to enhance its plugging capabilities. This modified asphalt exhibits excellent dispersibility and colloidal stability, effectively plugging micropores and microcracks in shale, preventing the intrusion of drilling fluid filtrate, thereby stabilizing the wellbore and improving drilling efficiency.

[0003] In contrast, the Chinese patent with announcement number CN211734265U discloses an asphalt dehydration and heating device, which includes a conveying cylinder body, a heating zone arranged in the middle of the conveying cylinder body, a heating pipe arranged in the heating zone, a feed port arranged on one side of the upper end of the conveying cylinder body, a discharge port arranged on one side of the lower end of the conveying cylinder body, an exhaust pipe arranged on the other side of the upper end of the conveying cylinder body, a conveying shaft arranged on the conveying cylinder body, and a drive assembly for driving the conveying shaft, thereby facilitating the introduction of asphalt material into the conveying cylinder body through the feed port, facilitating the stirring and conveying of the asphalt material through the conveying shaft, and facilitating the heating of the asphalt material through the heating zone, thereby effectively improving the quality of asphalt dehydration.

[0004] However, the above patent directly allows the exhaust gas to flow out naturally for subsequent treatment, which not only wastes the heat energy in the exhaust gas, but also fails to accelerate the air flow and drying in the conveying cylinder, and slows down the speed of asphalt dehydration. Therefore, a new equipment needs to be designed. Utility Model Content
