[0002] Asphalt is a dark brown complex mixture composed of hydrocarbon compounds with different molecular weights and their non-metallic derivatives. It is a high-viscosity organic liquid. Asphalt can be mainly extracted from petroleum, coal tar, etc. Asphalt has good waterproofness and adhesiveness and is widely used in road construction, building waterproofing, anti-corrosion projects and other fields. There are also different types and specifications of asphalt to meet different usage requirements and environmental conditions.

[0003] During the production process of asphalt, crude oil or other raw materials containing asphalt are distilled. The heavy residual part obtained after distillation is further processed to extract asphalt. Some modification treatments, quality inspections and adjustments are carried out on the asphalt. Then, the asphalt is stored for standby. When the existing asphalt storage tank discharges asphalt, generally the outlet pipe is opened to directly discharge the discharged asphalt, and it does not have the function of scraping the residual asphalt on the inner wall of the tank. When the asphalt storage tank is cleaned or the asphalt in the tank is discharged, the residual asphalt on the inner wall of the tank cannot be cleaned and discharged, resulting in a large amount of asphalt being wasted, which is not conducive to the discharge of asphalt and greatly reduces the discharge efficiency of asphalt.

The two cylinders 34 correspond to the two support blocks 33 one by one. The output end of the cylinder 34 is fixedly connected to the corresponding support block 33. The cylinder 34 is used to move the support block 33 and the support ring 32 upward. The support ring 32 is used to move the toothed transmission cylinder 3, the upper step 31 and the support ring 32 upward, providing support for the insertion of the toothed transmission cylinder 3 into the second gear 41.

[0023] As Figure 4 shown, a transmission rod 4 is rotatably connected to the inner wall of the rotating cylinder 2. A support frame 44 is fixedly connected to the upper surface of the upper cover plate 11. One end of the support frame 44 far from the upper cover plate 11 is fixedly connected to a motor 43.

[0026] As Figures 1-4As shown in the figure, the principle of the stable asphalt storage tank for asphalt production provided in this embodiment is as follows: When using the asphalt storage tank, a valve is connected to the flange at one end of the discharge pipe 14 away from the lower bottom plate 13 to control the discharge of asphalt. Asphalt enters the asphalt storage tank through the feed pipe 12 for storage.

The support block 33 drives the support ring 32 upward, and the support ring 32 drives the upper step 31 and the toothed transmission cylinder 3 upward. The motor 43 is controlled to drive the transmission rod 4 to rotate slowly. The transmission rod 4 drives the second gear 41 to rotate slowly. Subsequently, the toothed transmission cylinder 3 is inserted onto the second gear 41 and rotates slowly with the transmission rod 4. At this time, the transmission rod 4 drives the first gear 23 to rotate, the first gear 23 drives the rotating cylinder 2 to rotate, the rotating cylinder 2 drives the cross bar 21 to rotate, and the cross bar 21 drives the cleaning rod 22 to rotate to scrape the residual asphalt on the inner wall of the storage tank body 1. Subsequently, the residual asphalt on the inner wall of the storage tank body 1 flows onto the lower bottom plate 13 and is discharged through the discharge pipe 14. After scraping the asphalt on the inner wall of the storage tank body 1, the motor 43 is controlled to stop the rotation of the transmission rod 4 and the second gear 41. Then, the output end of the cylinder 34 retracts, driving the lower step 30 and the toothed transmission cylinder 3 downward. After the output end of the cylinder 34 is completely retracted, the toothed transmission cylinder 3 and the upper step 31 are completely disengaged from the second gear 41.
