[0002] Carbon black raw oil refers to an organic chemical substance obtained by refining and processing carbonaceous raw materials such as coal or petroleum. It is often used to produce carbon black. When processing carbon black raw oil, it needs to be preheated.

[0003] For example, in a crude oil preheater with the authorization announcement number "CN211821257U", after the temperature of the heating rod reaches a certain level, the water in the shell is continuously heated, and the emitted water vapor first contacts the oil pipeline to achieve the purpose of preheating the oil pipeline. However, since the heating rods of this crude oil preheater are located at the top and bottom, when heating the crude oil, the middle of the crude oil and the two sides of the crude oil are subjected to different temperatures, resulting in uneven preheating of the crude oil, thereby reducing the work quality. At the same time, the angle of the crude oil pipeline of this crude oil preheater is leveled, and when the preheated crude oil is discharged and collected, the crude oil is discharged too slowly, thereby reducing work efficiency. Utility Model Content

[0025] Working principle:

[0026] When preheating the raw material oil (the raw material oil is carbon black raw material oil), the worker opens the feed port 11 at the right end of the material pipe 6 through the solenoid valve at the right end, and then introduces the raw material oil to be preheated into the material pipe 6 through the feed port. After the raw material oil is introduced, the feed port 11 at the right end of the feed pipe 6 is closed through the solenoid valve. Then, the external power supply of the heating rod 9 is connected and started. The heating rod 9 generates heat and preheats the raw material oil in the material pipe 6;

[0027] Connect the external power supply of the first servo motor 202 and start it. The first servo motor 202 drives the rotating shaft 203 to rotate. The rotating shaft 203 drives the gear 204 to rotate. The gear 204 drives the gear disk 205 to rotate. Since the gear 204 is smaller than the gear disk 205, the rotation speed of the gear disk 205 is slower than that of the gear 204, which drives the insulation box 1 to rotate slowly. The insulation box 1 drives the heating rod 9 to rotate slowly, so that the heating rod 9 rotates slowly to preheat the raw material oil in the material pipe 6 evenly. When the air pressure generated by heating in the insulation box 1 is too high, the pressure relief valve 10 is opened to discharge the gas outside the insulation box 1;

[0028] After the raw material oil in the material pipe 6 is preheated, turn off the first servo motor 202, loosen the bolt on the rod body 5 to cancel the fixation of the rod body 5 on the base 4, then connect the external power supply of the second servo motor 302 and start it. The second servo motor 302 drives the threaded rod 302 to rotate, the threaded rod 302 drives the frame 304 to move upward, the frame 304 drives the roller 305 to move upward, and the roller 305 moves upward. The outer wall of the roller 305 contacts the lower end of the heat preservation box 1 to push the heat preservation box 1 upward. When the roller 305 pushes the heat preservation box 1 upward, the heat preservation box 1 will move with the block 7 fixed to the material pipe 6. Since the block 7 is movably connected to the vertical rod 8 through a pin shaft, when the roller 305 pushes the heat preservation box 1 upward, the heat preservation box 1 will swing counterclockwise around the movable connection between the block 7 and the vertical rod 8. After the heat preservation box 1 drives the material pipe 6 to swing 45 degrees, turn off the second servo motor 302, and then open the discharge port 12 of the material pipe 6 through the solenoid valve. The preheated raw material oil will finally be discharged from the discharge port 12 along the slope of the material pipe 6 and introduced into an external box for collection. After the preheated raw material oil is discharged from the material pipe 6, close the discharge port 12 of the material pipe 6, reverse the second servo motor 302 according to the above method to drive the heat preservation box 1 to reset. After the heat preservation box 1 is reset, turn off the second servo motor 302, and tighten the bolt again to fix the position of the rod body 5 to fix the heat preservation box 1. The preheating work of the raw material oil is completed through the above method.
