In addition, the staff can also use the lifting mechanism 12 to raise the adsorption plate 13 in the adsorption chamber 3, so as to facilitate the staff to repair and replace it.

[0021] The power mechanism 8 includes a first motor 81 fixed to the inner cavity of the casing 7. The output shaft of the first motor 81 is provided with a first screw sleeve rod 82 through a bevel gear transmission. The surface of the first screw sleeve rod 82 is meshed with a threaded sleeve block 83. The cutting ring 9 is fixed to one side of the surface of the threaded sleeve block 83.

[0027] Working principle: When in use, the asphalt fume can reach the spray tower 2 through the fume conveying pipe 1 through the external suction force or the thrust of the flue gas, and is input into the adsorption chamber 3 after being sprayed to reduce dust, and is discharged through the exhaust port 4 under the action of the adsorption plate 13. The working principle of the spray tower 2 is the existing technology, so it is not repeated. Since the asphalt fume contains a large amount of particles and has a strong adhesion ability, during the long-term transportation of the fume conveying pipe 1, part of the asphalt is easily attached to the inner cavity of the fume conveying pipe 1, thereby affecting the normal operation of the fume conveying pipe 1. When the device stops purifying the asphalt, the staff The detection port 6 can be rotated to make the waste pipe 5 open, and then the power mechanism 8 is used to make the cutting ring 9 clean the inner wall of the flue gas conveying pipe 1 under the action of the first motor 81, the first screw rod 82 and the threaded sleeve block 83, and the waste residue is discharged from the waste pipe 5, thereby improving the practicality of the device.
