Problems solved by technology
[0002] When rubber asphalt is processed, the rubber powder is combined according to a certain ratio of thickness and fineness, and a variety of high polymer modifiers are added, and fully swelled with the base asphalt under high temperature conditions (above 180°C) that are fully mixed. The modified asphalt cement material formed after the reaction is mixed in a reaction tank. In the prior art, the reaction tank is generally provided with a rotating shaft, and a stirring mechanism is arranged radially on the rotating shaft, such as the Chinese utility model patent "Modified Asphalt mixing mechanism" (Patent No. 201020202187.0), because the asphalt is relatively viscous, the mixing effect of the existing mixing device is not ideal

The invention relates to the technical field of rubber asphalt production devices, in particular to a reverse rubber asphalt reaction tank, which comprises a tank body. The tank body includes a shell and an inner tank, a heating pipe is arranged between the shell and the inner tank, the upper part of the tank body is provided with a rubber asphalt inlet and an additive inlet, a rubber asphalt outlet is arranged at the lower part of the tank body, two mutually parallel rotation shafts are disposed in the tank body, one of the rotation shafts is located above the other, and the two rotation shafts are opposite in rotation direction. The rotation shafts are equipped with a plurality of stirring units at an equal distance along the axial direction, each stirring unit includes two rotary arms uniformly arranged along the circumferential direction, the rotary arms of neighboring stirring units are mutually perpendicular, one ends of the rotary arms are connected to the rotation shafts and the other ends are equipped with stirring blades, and the rotary arms at a same position along the axial direction on the two rotation shafts are mutually perpendicular. With a scientific structure, the reverse rubber asphalt reaction tank provided by the invention utilizes reverse rotation of the two rotation shafts and interlaced rotary arms to stir rubber asphalt, and the stirring effect is good.
