Description

Technical Field

[0001] This utility model relates to the technical field of crude oil mixing, specifically to a static mixing device for heavy crude oil. Background Technology

[0002] Heavy crude oil refers to crude oil with a relative density between 0.90 and 1.00 g / cm³. It is generally dark in color, rich in gums and asphaltenes, and has a lower gasoline content than light and medium crude oil. When mixing heavy crude oil, conventional mixing equipment requires multiple feeding, power mixing, and discharging operations, reducing efficiency. Static mixers, on the other hand, can create cutting, shearing, rotating, and remixing effects between the two crude oils, achieving thorough mixing and saving time and energy compared to powered mixing devices.

[0003] However, existing static mixers are not convenient for adjusting the feed and monitoring of two types of crude oil. When the flow rate is too fast, the mixing effect is poor, and when the flow rate is too slow, the mixing efficiency is reduced. Therefore, a static mixing device for heavy crude oil is needed to improve the above problems. Utility Model Content

Multiple mixing unit blocks 7 are provided inside the mixing cylinder 4. The multiple mixing unit blocks 7 are fixedly connected in sequence and each pair of adjacent blocks have different directions.

[0029] Please see Figure 1-4 The mixing cylinder 4 is fixed by two connecting mechanisms. One of the connecting mechanisms includes a fixing ring 5 with multiple threaded holes. The fixing ring 5 is connected to the first fixing plate 3 by multiple connecting bolts 6, thereby limiting the mixing cylinder 4. The connection between the two fixing rings 5 ​​and the two first fixing plates 3 by the multiple connecting bolts 6 makes the mixing cylinder 4 more stable.

[0030] Please see Figure 1 and Figure 2The workbench 1 is equipped with a feeding mechanism, which includes two oil cylinders 9. A mounting frame 8 is fixedly installed on the workbench 1, and the two oil cylinders 9 are fixedly installed on the mounting frame 8. The bottom ends of the two oil cylinders 9 are connected to an oil inlet pipe 10, and both oil inlet pipes 10 are equipped with solenoid valves 11. One end of the mixing cylinder 4 is connected to a discharge pipe 12. By adding different oils into the two oil cylinders 9, and by opening the two solenoid valves 11, the oils in the two oil cylinders 9 are discharged into the mixing cylinder 4 through the two oil inlet pipes 10. The mixing operation is carried out through the cooperation of multiple mixing unit blocks 7. The mixed oil is discharged through the discharge pipe 12, thereby realizing the static mixing operation of the oil. The two solenoid valves 11 facilitate the observation and adjustment of the flow rate according to actual needs.

[0031] Please see Figure 1 and Figure 2 The bottom of the workbench 1 is provided with a support mechanism, which includes four bases 13. The four bases 13 are symmetrically fixedly installed at the bottom of each leg 2. The four bases 13 make the legs 2 more stable, thereby making the workbench 1 more stable.

[0032] Please see Figure 1 , Figure 2 and Figure 4 It should also be noted that a transparent tube 14 is provided on the discharge pipe 12. The transparent tube 14 facilitates observation of the state of the mixed oil and allows for timely adjustment.

[0033] Please see Figure 1 and Figure 2 Two second fixing plates 15 are symmetrically fixed on the workbench 1. The mixing cylinder 4 is fixedly connected to the two second fixing plates 15. The two second fixing plates 15 support the mixing cylinder 4 and make the mixing cylinder 4 more stable.

[0035] In summary, when using this static mixing device for heavy crude oil, the two fixing rings 5 ​​and the two first fixing plates 3 are connected by rotating the connecting bolts 6 in sequence, thereby fixing the mixing cylinder 4. Different oils are added to the two oil cylinders 9, the two solenoid valves 11 are opened, and the oils in the two oil cylinders 9 are discharged into the mixing cylinder 4 through the two oil inlet pipes 10. The mixing operation is carried out by the cooperation of multiple mixing unit blocks 7. Since the directions of the multiple mixing unit blocks 7 are staggered, the oils are cross-mixed. The mixed oil is discharged through the discharge pipe 12. The transparent pipe 14 facilitates the observation of the state of the mixed oil and allows for timely adjustment of the feed rate and flow rate through the solenoid valves 11.
