Description

Technical Field

[0001] This utility model relates to the field of drag-reducing agent storage technology, and in particular to a storage tank for drag-reducing agents in crude oil pipelines. Background Technology

[0002] Drag reducers are viscoelastic polymers. When injected into pipelines, the polymer molecules interact with the flowing crude oil, absorbing energy from the thin interlayer of the flow and interfering with the entry of liquid molecules from the buffer zone into the turbulent core, thereby reducing the degree of turbulence and flow resistance.

[0003] Drag reducers are usually stored in dedicated storage tanks. Because drag reducers will precipitate during long-term storage, they need to be stirred before use to ensure their fluidity. If they are added directly to the pipeline without stirring, the drag reduction effect will be greatly reduced. The current method of stirring drag reducers is usually for workers to use stirring rods, which is time-consuming and labor-intensive. Utility Model Content

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please see Figure 1- Figure 5 This utility model provides an embodiment of a storage tank for drag-reducing agents in crude oil pipelines, comprising a tank body 1 and a cover 2, as well as a bearing seat 5, a stirring rod 6, and a mounting bracket 7. The upper side surface of the tank body 1 is threaded, and the cover 2 is threadedly connected to the upper end of the tank body 1. A bearing seat 5 is fixedly installed at the center of the bottom of the tank body 1, and the stirring rod 6 is rotatably connected to the upper end of the bearing seat 5. A mounting bracket 7 is fixedly installed in the middle of the tank body 1, and a bearing seat 8 is fixedly installed at the center of the upper end of the mounting bracket 7. A connecting shaft 9 is rotatably connected to the end of the bearing seat 8, and a bevel gear 10 is fixedly installed on the surface of the connecting shaft 9. A bearing seat 3 11 is fixedly installed on the inner wall of the tank body 1, and a rotating shaft 12 is rotatably connected to the end of the bearing seat 3 11. A bevel gear 2 13 is fixedly connected to one end of the rotating shaft 12. An annular protrusion is provided on the inner wall of the tank body 1, and the mounting bracket 7 is fixed by bolts. Installed on the annular protrusion on the inner wall of the storage tank 1, the lower end of the connecting shaft 9 is fixedly connected to the upper end of the stirring rod 6. When the crude oil pipeline drag reducing agent storage tank needs to be used, first hold the rotating handle 16 and turn it. The rotating shaft 12 will rotate at the same time, and the connecting shaft 9 will rotate at the bearing seat 8. The stirring rod 6 will rotate at the bearing seat 5. The stirring rod 6 will stir the crude oil pipeline drag reducing agent in the storage tank 1. Turning the handle 16 makes stirring the crude oil pipeline drag reducing agent easier. When the stirring rod 6 is stirring the crude oil pipeline drag reducing agent in the storage tank 1, the locking block 14 at the upper end of the connecting shaft 9 will drive the locking seat 15 to rotate at the same time, and the cover 2 will be rotated open at the same time. In this way, the crude oil pipeline drag reducing agent is stirred and the cover 2 is opened at the same time, which facilitates the quick opening and use of the crude oil pipeline drag reducing agent, thus avoiding the time-consuming and laborious problem of manual stirring.

[0021] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5In this embodiment, bevel gear 10 meshes with bevel gear 13. A rotating handle 16 is fixedly connected to one end of the rotating shaft 12. The surface of the rotating handle 16 is provided with anti-slip texture. The surface of the storage tank body 1 is uniformly distributed with annular anti-slip texture. One end of the rotating shaft 12 passes through the storage tank body 1. An O-ring seal 17 is provided at the connection between the rotating shaft 12 and the storage tank body 1. An observation glass plate 4 is fixedly connected to the lower end of one side of the storage tank body 1. The observation glass plate 4 is used to observe the remaining amount of drag-reducing agent in the crude oil pipeline. Multiple rollers 3 are provided at the lower end of the storage tank body 1. The rollers 3 are distributed in an annular pattern, and the included angle between adjacent rollers 3 is 60 degrees. The rotating handle 16 is used to pull the storage tank body 1. A locking block 14 is fixedly connected to the upper end of the connecting shaft 9. A locking seat 15 is fixedly connected to the lower end of the cover 2. The locking block 14 is adapted to the locking seat 15, and the locking block 14 and the locking seat 15 are slidably connected. The surface of the storage tank body 1 is evenly distributed with annular anti-slip textures. The lower end of the storage tank body 1 is provided with multiple rollers 3. During use, the surface of the storage tank body 1 often adheres to a large amount of oil stains. The annular anti-slip textures of the storage tank body 1 facilitate the handling of the storage tank body 1, and the rollers 3 facilitate the movement of the storage tank body 1. The O-ring seal 17 is used to prevent the crude oil pipeline drag reducing agent from flowing out from the gap between the rotating shaft 12 and the storage tank body 1 when pouring out the crude oil pipeline drag reducing agent. The mounting bracket 7 is used to ensure the stability of the rotation of the stirring rod 6. The observation glass plate 4 facilitates the observation of the remaining crude oil pipeline drag reducing agent in the storage tank body 1, and facilitates the identification of the storage tank body 1 with insufficient crude oil pipeline drag reducing agent by the staff.

[0022] When using the crude oil pipeline drag reducer, first hold the rotating handle 16 and rotate it. The rotating handle 16 is fixedly connected to one end of the rotating shaft 12. The rotating shaft 12 rotates simultaneously. One end of the rotating shaft 12 is fixedly connected to a bevel gear 13. The bevel gear 13 meshes with the bevel gear 10. The bevel gear 10 is fixedly installed on the surface of the connecting shaft 9. The connecting shaft 9 rotates at the bearing seat 8. The lower end of the connecting shaft 9 is fixedly connected to the upper end of the stirring rod 6. The stirring rod 6 rotates at the bearing seat 5. The stirring rod 6 stirs the crude oil pipeline drag reducer in the storage tank 1. The surface of the rotating handle 16 is provided with anti-slip texture, making it easier to stir the crude oil pipeline drag reducer by rotating the handle 16.

[0023] When the stirring rod 6 is stirring the crude oil pipeline drag reducer in the storage tank 1, the locking block 14 at the upper end of the connecting shaft 9 simultaneously drives the locking seat 15 to rotate. The locking seat 15 is slidably connected to the locking block 14. The locking seat 15 is fixedly installed at the lower end of the cover 2. The cover 2 is rotated open at the same time. In this way, the crude oil pipeline drag reducer is stirred and the cover 2 is opened at the same time, which facilitates the quick opening and use of the crude oil pipeline drag reducer.

[0024] The surface of the storage tank 1 is evenly distributed with annular anti-slip textures. The lower end of the storage tank 1 is equipped with multiple rollers 3. During use, a large amount of oil stains often adhere to the surface of the storage tank 1. The annular anti-slip textures of the storage tank 1 facilitate the handling of the storage tank 1, and the rollers 3 facilitate the movement of the storage tank 1.

[0025] O-ring 17 is used to ensure the sealing of the storage tank body 1 and prevent the crude oil pipeline drag reducer from flowing out from the gap between the rotating shaft 12 and the storage tank body 1 when the crude oil pipeline drag reducer is poured out.

[0026] The stirring rod 6 is relatively long, and the mounting bracket 7 is used to ensure the stability of the stirring rod 6 during rotation.

[0027] The observation glass plate 4 facilitates the observation of the remaining amount of crude oil pipeline drag reducing agent in the storage tank 1, and helps staff identify storage tank 1 with insufficient crude oil pipeline drag reducing agent.

[0028] Through the above steps, when the crude oil pipeline drag reducing agent storage tank needs to use the crude oil pipeline drag reducing agent, hold the rotating handle 16 and rotate it. At the same time, the cap 2 is rotated open. This completes the stirring of the crude oil pipeline drag reducing agent while opening the cap 2, thus facilitating the quick opening and use of the crude oil pipeline drag reducing agent and avoiding the time-consuming and laborious problem of manual stirring.
