[0002] The coal tar processing process generally produces about 50% to 60% asphalt, which is a bulk product of tar processing. Modified asphalt is currently the main downstream product of asphalt, mainly used in the electrolytic aluminum industry to produce prebaked anodes, prepare battery rods or electrode binders.

[0003] According to a search, Chinese patent document publication number CN221452331U discloses a modified asphalt production device. The device uses a feed pipe for feeding. When feeding, a movable cover must be opened first. The movable cover prevents impurities from the outside air from entering the chamber through the feed pipe, effectively isolating the chamber from contamination. After the modified asphalt enters the production chamber, an external control device controls the control motor, which drives the heating pipe to rotate. The rotation of the heating pipe drives the first heat conducting rod to rotate, mixing and stirring the modified asphalt inside.

[0004] However, in actual use, the above-mentioned production device directly uses a heating tube to drive a heat-conducting rod to stir the modified asphalt raw material. Since the asphalt raw material has a high viscosity, the stirring method of the production device will cause a large amount of raw material to adhere to the outer surface of the heating tube, resulting in a poor heating effect. At the same time, the stirring method is single, the material fluidity is poor, and coking is easily formed on the inner wall of the reactor. Utility Model Content

[0032] See also Figure 1-Figure 5A modified asphalt production device includes a kettle body 1, an inner cylinder 2 is arranged inside the kettle body 1, and a kettle cover 3 is installed on the top of the kettle body 1. The top of the kettle cover 3 is connected to a cover shell 4 by bolts. A connecting plate 5 is fixedly connected to the inside of the cover shell 4. A rotating shaft 6 is rotatably connected to the inside of the connecting plate 5. The bottom end of the rotating shaft 6 is fixedly connected to a worm 7, and the outer surface of the rotating shaft 6 is fixedly connected to a first gear 8. The transmission of the worm 7 is connected to a worm wheel 9. The end center of the worm wheel 9 is fixedly connected to a rotating plate 10. One end of the rotating plate 10 is fixedly connected to the rotating plate 10. The connecting rod 11 is connected by rotating the shaft, and one end of the connecting rod 11 is connected to the rotating plate 2 12 by rotating the shaft. One end of the rotating plate 2 12 is fixedly connected to the second gear 13, and the second gear 13 is meshed with the gear rod 14. The inside of the gear rod 14 is fixedly connected to the transmission rod 15, and a key groove 16 is provided on the outer surface of the transmission rod 15, and the outer surface of the transmission rod 15 is clamped with the third gear 17 near the top. The bottom end of the transmission rod 15 is connected to the agitator 18 through a flange, and the reduction motor 19 is installed on the top of the cover 4.

[0033] Specifically, the top of the kettle cover 3 is fixedly connected to the feed pipe 20, and the bottom of the kettle body 1 is fixedly connected to the discharge valve 21. The advantage is that by connecting the feed pipe 20 to the conveying equipment, the raw material of the modified asphalt is conveyed into the inner barrel 2 by the conveying equipment, and after sufficient mixing and reaction, the modified asphalt is finally discharged by opening the discharge valve 21.

[0034] Specifically, a sandwich is provided between the kettle body 1 and the inner barrel 2, within which are installed several heating tubes 22. This has the advantage that, since heating is often required during the reaction of the modified asphalt feedstock, the outer wall of the inner barrel 2 can be heated by the heating tubes 22, thereby heating the modified asphalt feedstock inside the inner barrel 2 and promoting a full reaction between the feedstocks.

[0035] Specifically, four support rods 23 are fixedly connected to the bottom of the kettle body 1, and connecting rods are fixedly connected between the support rods 23. Advantageously, the support rods 23 can support the kettle body 1, and the connecting rods can strengthen the connection strength between two adjacent support rods 23, so that the entire production device can be stably placed.

In this way, the connecting rod 11 drives the second rotating plate 12 to swing back and forth, thus enabling the second gear 13 to rotate back and forth. In turn, the second gear 13 can drive the rack rod 14 to reciprocate up and down. In this way, the rack rod 14 drives the transmission rod 15, and the transmission rod 15 drives the agitator 18 and the anchor-shaped stirring paddle 181 to reciprocate up and down. In this way, the vertical position of the anchor-shaped stirring paddle 181 can be continuously changed during the stirring process of the raw materials, so that the raw materials can be more fully stirred and the flow rate of the raw materials is increased, which is conducive to preventing the raw materials from forming coke on the inner barrel 2.

Advantageously, when transmission rod 15 reciprocates up and down under the drive of rack rod 14, keyway 16 on the outer surface of transmission rod 15 mates with a key on the inner wall of gear number 3 17. This allows gear number 3 17 to continue rotating transmission rod 15 without interfering with the reciprocating motion of transmission rod 15.

[0040] During use, the raw materials of the modified asphalt are first transported into the inner cylinder 2 through the feed pipe 20, and then the outer wall of the inner cylinder 2 can be heated through the heating pipe 22, so that the modified asphalt raw materials inside the inner cylinder 2 are heated, promoting the fusion between the raw materials, and then the reduction motor 19 is started to drive the rotating shaft 6 to rotate, and the rotating shaft 6 then drives the No. 1 gear 8 to rotate, and the No. 1 gear 8 drives the No. 3 gear 17 to rotate, and the No. 3 gear 17 drives the transmission rod 15 to rotate, and the transmission rod 15 drives the agitator 18 and the anchor-shaped stirring paddle 181 to rotate, so that the raw materials in the inner cylinder 2 can be stirred, and while the rotating shaft 6 drives the No. 1 gear 8 to rotate, it can also drive the worm. 7 rotates, the worm 7 drives the worm wheel 9 to rotate, the worm wheel 9 drives the rotating plate 10 to rotate, and the rotating plate 10 drives the connecting rod 11, so that the connecting rod 11 drives the rotating plate 2 12 to swing back and forth, so that the No. 2 gear 13 can rotate back and forth, and then the No. 2 gear 13 can drive the rack rod 14 to reciprocate up and down, so that the rack rod 14 drives the transmission rod 15, and the transmission rod 15 drives the agitator 18 and the anchor-shaped stirring paddle 181 to reciprocate up and down, so that the vertical position of the anchor-shaped stirring paddle 181 can be continuously changed during the mixing of the raw materials, so that the raw materials can be more fully mixed; after the raw materials are fully reacted, the modified asphalt is discharged by opening the discharge valve 21.
