[0043] The purification device 61 is an activated carbon adsorption device. The activated carbon has a large specific surface area and rich microporous structure, which can absorb asphalt fume and other organic pollutants in the exhaust gas, reducing the harm to the workers' health.

[0044] The feed port 32 is opened on the side of the sliding ring 31. When stirring, the feed port 32 can be located on the inner side of the mixing tank 2, thereby preventing the exhaust gas from being discharged and affecting the surrounding environment.

[0055] At the same time, the exhaust fan 62 is started to exhaust air from the interior of the purification device 61, so that the exhaust gas enters the interior of the purification device 61 through the air pipe 63, so that the purification device 61 purifies the exhaust gas and then discharges it;

[0057] Compared with the related art, the asphalt mixture regeneration stirring device provided by the utility model has the following beneficial effects:

[0058] By installing a protective frame 1 on the outer side of the mixing tank 2, the mixing tank 2 can be protected to prevent workers from being burned by spraying the mixing tank 2, thereby increasing safety.
