Description

Technical Field

[0001] The utility model relates to the technical field of coal tar storage tanks, in particular to a coal tar storage tank with internal circulation of natural gas hot air. Background Art

[0002] There are two traditional methods of sampling in asphalt storage tanks: one is to dismantle the manhole on the top of the tank and use the "deep well water extraction" method to take samples. The disadvantage of this method is that the operator needs to climb to the top of the tank to take samples, which is risky, and the surface asphalt is taken out, and the sample asphalt index is inaccurate; the other is to dismantle the flange at the outlet end of the asphalt output pump at the bottom of the tank and take samples by gravity. The disadvantage of this method is that the operation process is relatively complicated and difficult to control, and the sample taken out is the asphalt at the bottom of the tank, which cannot accurately reflect the asphalt index. Both of the above sampling methods cannot take samples from different positions of the storage tank as needed, and cannot truly and accurately reflect the asphalt index in the storage tank.

[0003] Among them, announcement number CN207737865U discloses an asphalt storage tank with a steam heating device, including a tank body and a steam heating device, the steam heating device includes a steam pipe spirally wound on the tank body, hot steam circulates in the steam pipe; a plurality of sampling holes are distributed on the tank body from top to bottom, a sampling tube is arranged in the sampling hole, the outer end of the sampling tube extends out of the tank body, and an asphalt flow outlet is arranged at the side and lower part of a section of the sampling tube located outside the tank body, and the asphalt flow outlet is externally connected to a sample storage device; a sampling piston is slidably arranged in the sampling tube, and the piston head is sealed and connected to the sampling tube inside the asphalt flow outlet when no sampling is performed; the sampling piston retreats when sampling, and the piston head is sealed and connected to the sampling tube outside the asphalt flow outlet. There are still defects in this technical solution:
