[0024] Reference Figure 1-2 As shown, it is a preferred embodiment provided by the utility model.

[0025] The utility model provides a warm-mix emission-reducing high-precision asphalt storage device, comprising an outer cylinder 100 and an inner cylinder 200, wherein the inner cylinder 200 is placed in the outer cylinder 100, and the inner periphery of the outer cylinder 100 and the outer periphery of the outer cylinder 100 are arranged at intervals to form an arrangement interval; the inner cylinder 200 has an inner cavity for accommodating asphalt, and the top of the inner cavity has a top opening, the top of the outer cylinder 100 is connected to a feed pipe 110, and the discharge port of the feed pipe 110 is arranged opposite to the top opening, a stirring shaft 300 is provided in the middle of the inner cavity, and a driving motor 310 is connected to the top of the stirring shaft 300;

[0026] A rotating shaft 401 is provided at the lower part of the inner cylinder 200, the inner end of the rotating shaft 401 is placed in the inner cavity, the outer end of the rotating shaft 401 passes through the arrangement interval and passes through the outer cylinder 100 to form an outer section, and the outer end of the outer section is fixedly connected to the discharge pipe 402; a transmission motor 410 is provided on the outer periphery of the outer cylinder 100, the transmission motor 410 drives the transmission gear 411 to rotate, and a rotating gear 412 is sleeved on the outer periphery of the outer section, and the transmission gear 411 is meshed with the rotating gear 412;

[0027] A heating structure is provided in the arrangement interval.

[0028] The above-mentioned warm-mix emission-reduction type high-precision asphalt storage device directly heats the inner cylinder 200 through the heating structure so that the temperature in the inner cavity reaches the set range, and drives the stirring shaft 300 through the driving motor 310 to evenly stir the asphalt in the inner cavity. The transmission motor 410 drives the rotating shaft 401 located at the lower part to rotate, so that when the rotating shaft 401 rotates in the reverse direction, the asphalt in the lower part of the inner cavity forms a backflow, further improving the overall stirring effect of the asphalt and the warm-mix modifier, making the chemical reaction between the two more complete and the finally formed warm-mix reaction-type modified asphalt having better performance. When the rotating shaft 401 rotates in the forward direction, the finished product can be more effectively output from the tank into the production main pipeline.

[0029] Specifically, the heating structure includes a heating pipeline 501, and along the direction from bottom to top, the heating pipeline 501 is arranged spirally upward along the outer circumference of the inner cylinder 200.

[0030] The arrangement interval is also provided with a heat insulation layer 502, which completely fills the arrangement interval, and the heating pipeline 501 is arranged between the heat insulation layer 502 and the inner cylinder 200.

[0031] Specifically, the heating structure is connected to the control electrical box, and the heating structure allows the asphalt in the asphalt tank to be evenly heated; the thermal insulation layer 502 is used to prevent internal heat loss. Through the synergistic effect of the heating layer and the thermal insulation layer 502, the asphalt in the tank can be kept at a long-term stable temperature, providing a solid environmental foundation for the preparation of high-quality modified asphalt.

In this way, the plurality of groups of stirring transverse shafts 320 in a cross shape can increase the contact area between the asphalt and the warm mix modifier, so that the asphalt can be fully stirred, thereby improving the stirring uniformity of the asphalt.

[0036] Specifically, the protruding head 321 is convexly arranged above the stirring horizontal axis 320. In this way, the stirring area of ​​the stirring horizontal axis 320 is increased, and the stirring effect is improved.

[0037] Specifically, the protruding head 321 is convexly arranged below the stirring horizontal axis 320. In this way, the stirring area of ​​the stirring horizontal axis 320 is increased, and the stirring effect is improved.

In this way, the transmission motor 410 is fixed on the outer periphery of the outer cylinder 100 through the design of the protection bracket 120. At the same time, damage to the transmission shaft of the transmission motor 410 and the transmission gear 411 is avoided, which greatly improves the safety performance.
