[0036] The surface of the stirring plate 13 is provided with evenly distributed through holes.

[0037] The heating tube 15 is arranged in an up-and-down spiral.

[0038] When the asphalt raw material is stirred, since the asphalt has a certain viscosity, the asphalt is easy to adhere to the inner wall of the stirring tank during stirring and mixing, and the stirring shaft can only stir the raw materials in the area of ​​the rotation track. At this time, the local raw materials attached to the inner wall of the stirring tank cannot be fully stirred, thereby affecting the stirring quality. When the device is used, an external power supply is provided, and a stirring plate 13 is provided on the outer side of the stirring shaft 6. The stirring plate 13 can achieve the purpose of stirring. At the same time, a plurality of through holes are provided on the surface of the stirring plate 13. At this time, the asphalt raw material can enter the other side through the through holes. At this time, the stirring quality can be guaranteed, and the heating tube 15 can heat the water inside the insulation tube 2, thereby ensuring the fluidity of the raw materials near the inner wall of the stirring tank 1. At this time, the stirring motor 5 drives the stirring shaft 6 to rotate, and the stirring shaft 6 can drive the outer connecting plate 12, the stirring plate 13 and the scraper 14 to rotate. At this time, the raw material mixing quality can be guaranteed, and the set gas treatment mechanism 8 can treat the generated harmful gases to ensure the air quality;

[0039] In this embodiment, the discharge pipe 10 is provided to facilitate the discharge of materials, and the top cover 7 is movable to facilitate the feeding of materials.

At this time, the air pump 802 of the device is started to pump the gas into the processing frame 801, and the harmful gas is fully in contact with the water body. At this time, the gas can be treated to a certain extent, and after being treated by the activated carbon plate net 806, the air quality can be further guaranteed;

[0050] In this embodiment, when it is stirred, the harmful gas generated is pumped into the water body inside the treatment frame 801 through the air pump 802 and comes into contact with the water body. When the harmful gas is acidic, the water body can be set to alkaline for neutralization. According to actual conditions, the water body that reacts with the harmful gas can be set for treatment work. The one-way valve 805 can ensure that the gas can only flow in one direction to avoid backflow of the water body. At the same time, the drain plug 807 is set to facilitate the discharge of the water body for replacing the water body.
