[0030] The specific working process of the purging system 2 of asphalt production pipeline 1 of the utility model is as follows: when asphalt pump 103 stops working, the flue gas of heat conducting oil furnace 201 is introduced into asphalt production pipeline 1 by exhaust pipeline 202, and the flue gas generated by heating of heat conducting oil furnace 201 is purged to asphalt in material pipeline 102 and asphalt pump 103, so that the asphalt in material pipeline 102 is purged back to asphalt tank 101. In addition, as Figure 2 shown, in another embodiment, asphalt in asphalt tank 101 is transported to loading opening into tank car or into other asphalt tank by material pipeline 102 and asphalt pump 103, and after asphalt pump 103 stops working, the flue gas of heat conducting oil furnace 201 can be purged to asphalt in material pipeline 102 until the residual asphalt in material pipeline 102 enters tank car or other asphalt tank.

Since the heat conducting oil furnace 201 is used for the heating treatment link of the asphalt in the asphalt production process, the embodiment is provided with the exhaust pipeline 202, the high-temperature flue gas generated by the heat conducting oil furnace 201 is used for blowing the asphalt production pipeline 1, the asphalt in the exhaust pipeline 202 is kept in a flow state under high temperature, the solidification phenomenon caused by the temperature drop is avoided, and the secondary utilization of the flue gas of the heat conducting oil furnace 201 is realized; compared with the prior art, the residual asphalt in the material pipeline 102 and the asphalt pump 103 is discharged in time, the heating work on the residual asphalt in the next production is avoided, and the cost in the asphalt production process is reduced.
[0032] In the preferred embodiment of the utility model, the exhaust pipeline 202 is provided with a filtering unit 3, and the filtering unit 3 is installed at the exhaust port. In order to avoid that the particulate matters or trace elements contained in the flue gas discharged by the heat conducting oil furnace 201 enter the material pipeline 102 through the exhaust pipeline 202 to produce adverse reactions on the asphalt and affect the performance of the asphalt, the filtering unit 3 is arranged in the exhaust pipeline 202, and the filtering unit 3 can filter the particulate matters or trace elements in the flue gas or the heat conducting oil furnace 201.

[0036] In the preferred embodiment of the utility model, the blowing system 2 further comprises a one-way valve 6, and the one-way valve 6 is located at the connection position of the exhaust pipeline 202 and the material pipeline 102.

[0040] It should be noted that the type of the pressure sensor and the controller is not described in the utility model.

When the asphalt pump 103 stops transporting asphalt, the operator can open the main valve 8, allowing the flue gas from the thermal oil furnace 201 to enter the exhaust pipe 202, thereby initiating the purging operation of the process pipeline; after the asphalt in the process pipeline is emptied, the operator can close the main valve 8.
[0045] like Figure 3 As shown, in a preferred embodiment of this utility model, an insulation layer 9 is provided on the outer side of the exhaust pipe 202, and the insulation layer 9 is detachably connected to the exhaust pipe 202.
