Asphalt foaming device in warm mixing process of asphalt mixture

The utility model relates to an asphalt foaming device in the warm mixing process of asphalt mixture, which is used for solving the problem of the mixing of hot mixing asphalt. The utility model adopts the technical scheme that the asphalt foaming device is provided with a water storage mechanism, a quantitative water supply mechanism and an asphalt foaming mechanism, wherein the water storage mechanism is connected with the quantitative water supply mechanism; the quantitative water supply mechanism is connected with the asphalt foaming mechanism; an electrical appliance control mechanism is connected with the water storage mechanism, the quantitative water supply mechanism and an air blown asphalt foaming mechanism respectively; an asphalt foaming pipe of the air blown asphalt foaming mechanism is of the double-layer casing structure, the outer-layer casing is a conduction oil heating casing, and the inner-layer core pipe is a foamed asphalt generating core pipe; a fixed helical blade is arranged at the middle part of the pipe cavity of the foamed asphalt generating core pipe; and a radial fixed plate is arranged in the pipe cavity behind the fixed helical blade. The asphalt foaming device can effectively solve the problems that the heat energy is wasted, and the construction is not convenient, has the advantages of simple and practical structure, simple construction and the like, is applicable to the warm mixing process of the asphalt mixture for road paving and is jointed and matched with other devices.
