Abstract
Description
Technical Field
[0001] This utility model relates to a pour point depressant synthesis device, specifically a petroleum lubricating oil pour point depressant synthesis device, belonging to the field of pour point depressant technology. Background Technology
[0002] Pour point depressants are chemicals that lower the pour point of lubricating oils. They are generally high-molecular-weight organic compounds, and many varieties are the same as those used in oil and gas extraction. Commonly used varieties in lubricating oils include alkyl naphthalenes, polymethyl methacrylates, and polyalphaolefins. These are produced by using soft wax-cracked olefins as raw materials, which are then appropriately refined and polymerized in the presence of a Ziegler-Natta catalyst.
[0003] Utility model patent CN217887769U discloses a crude oil pour point depressant synthesis device, relating to the technical field of synthesis devices. It includes a base plate, an inner chamber, an outer chamber, and a lead screw. The outer chamber is mounted on the top of the base plate, and a control panel is mounted on the top of one end of the outer chamber. A handle is mounted on the outer side of the door. This crude oil pour point depressant synthesis device, by setting multiple material tanks, can simultaneously add different components in proportion into the chamber, avoiding the occurrence of stratification between different components caused by all materials being added sequentially from a single feed port.
[0004] To facilitate the synthesis of pour point depressants, a mixing device is used to mix various raw materials. Although the synthesis device in the aforementioned patent improves the stirring efficiency, the raw materials remain inside the container after mixing, making cleaning time-consuming and labor-intensive. Therefore, we provide a petroleum lubricating oil pour point depressant synthesis device to solve the above problems. Utility Model Content

[0016] This invention provides a device for synthesizing a petroleum lubricating oil pour point depressant, which has the following beneficial effects:
[0017] This petroleum lubricating oil pour point depressant synthesis device uses a rotating shaft to drive a vertical scraper to scrape and clean the inner wall of the mixing tank, thereby cleaning the side wall of the mixing tank and improving the cleaning efficiency of the mixing tank. During mixing, it also prevents raw materials from adhering to the inside of the mixing tank, improving the raw material mixing efficiency. The vertical scraper is connected to the rotating shaft by a connecting rod.

[0018] This petroleum lubricating oil pour point depressant synthesis device adds pour point depressant raw materials into a mixing tank through an inlet.

The fixed outer shell restricts the linkage shaft, and when the rotating shaft rotates, it drives the linkage shaft to revolve around the central axis. The fixed outer shell is supported and fixed by a support rod. By setting the direction of the first and second tumbling blades, the flow direction of the raw materials inside the mixing tank can be disrupted, allowing the raw materials inside the mixing tank to tumble up and down, thus improving the mixing efficiency of the raw materials.

[0026] This invention provides a device for synthesizing a petroleum lubricating oil pour point depressant.
[0027] Please see Figure 1, Figure 2 , Figure 3 and Figure 4 The system includes a mixing tank 1, with a rotating shaft 5 rotatably connected inside the mixing tank 1. A motor 7 is fixedly connected to the surface of the mixing tank 1, with the output end of the motor 7 fixedly connected to the rotating shaft 5. A feed inlet 2 is fixedly connected to the top of the mixing tank 1. Pour depressant raw materials are added into the mixing tank 1 through the feed inlet 2. The rotating shaft 5 is rotated by the motor 7 to mix the raw materials inside the mixing tank 1.
[0028] The bottom of the mixing tank 1 is fixedly connected to the discharge pipe 3, and the surface of the discharge pipe 3 is fixedly connected to the control valve 4. The top of the control valve 4 is fixedly connected to the mixing tank 1. The discharge pipe 3 facilitates the flow of the synthesized pour point depressant inside the mixing tank 1 out of the mixing tank 1. The control valve 4 controls the opening and closing of the discharge pipe 3.
[0029] The mixing tank 1 is equipped with a vertical scraper 10 and a linkage rotating shaft 14 inside. The vertical scraper 10 is slidably connected to the inner wall of the mixing tank 1. By rotating the rotating shaft 5, the vertical scraper 10 is driven to scrape and clean the inner wall of the mixing tank 1, thereby cleaning the side wall of the mixing tank 1, improving the cleaning efficiency of the mixing tank 1, and preventing raw materials from adhering to the inside of the mixing tank 1 during mixing, thus improving the raw material mixing efficiency.
[0030] A mixing rod 6 is fixedly connected to the surface of the rotating shaft 5, and a horizontal scraper 8 is fixedly connected to the bottom of the rotating shaft 5. The horizontal scraper 8 is slidably connected to the mixing barrel 1. The rotating shaft 5 drives the mixing rod 6 to rotate, thereby mixing the raw materials inside the mixing barrel 1. The rotating shaft 5 drives the horizontal scraper 8 to rotate, scraping the bottom of the mixing barrel 1 to prevent the raw materials from piling up at the bottom of the mixing barrel 1, thus improving the raw material mixing efficiency. When cleaning the mixing barrel 1, the horizontal scraper 8 can scrape the inner bottom wall of the mixing barrel 1, improving the cleaning efficiency of the mixing barrel 1.
[0031] A connecting rod 9 is fixedly connected to the surface of the vertical scraper 10, and the connecting rod 9 is fixedly connected to the rotating shaft 5. A first turning blade 17 and a second turning blade 18 are fixedly connected to the surface of the linkage rotating shaft 14. The vertical scraper 10 and the rotating shaft 5 are connected together through the connecting rod 9. The rotation of the linkage rotating shaft 14 drives the first turning blade 17 and the second turning blade 18 to rotate, thereby turning the raw materials inside the mixing tank 1 up and down, breaking the axial flow and radial flow of the raw materials, and improving the mixing efficiency of the raw materials inside the mixing tank 1.
[0032] A fixing sleeve 11 is fixedly connected to the middle of the mixing tank 1. A first sprocket 12 is fixedly connected to the bottom end of the fixing sleeve 11. The first sprocket 12 is connected to a second sprocket 13 via chain drive. The second sprocket 13 is fixedly connected to the linkage shaft 14. The fixing sleeve 11 fixes the first sprocket 12. When the second sprocket 13 rotates around the rotation shaft 5, it is restricted by the first sprocket 12 and drives the linkage shaft 14 to rotate, so that the linkage shaft 14 revolves around the revolution and rotates on its own axis, thereby improving the efficiency of the linkage shaft 14 in mixing raw materials.
[0033] A fixed housing 15 is fixedly connected to the surface of the rotating shaft 5. The top end of the fixed housing 15 is rotatably connected to the fixed sleeve 11, and the top end of the linkage rotating shaft 14 is rotatably connected to the fixed housing 15. The fixed housing 15 limits the linkage rotating shaft 14. When the rotating shaft 5 rotates, it drives the linkage rotating shaft 14 to revolve.
[0034] A support rod 16 is fixedly connected to the surface of the fixed outer shell 15, and the bottom end of the support rod 16 is fixedly connected to the rotating shaft 5. The first flipping blade 17 and the second flipping blade 18 rotate in opposite directions. The support rod 16 supports and fixes the fixed outer shell 15. By setting the direction of the first flipping blade 17 and the second flipping blade 18, the flow direction of the raw materials inside the mixing tank 1 can be disturbed, so that the raw materials inside the mixing tank 1 can be flipped up and down, thereby improving the mixing efficiency of the raw materials.
[0035] The control valve 4 and the electric motor 7 are existing technologies, and their detailed parameters and models will not be described in detail in this application.
[0036] In use, this invention involves adding pour point depressant raw materials into the mixing tank 1 through the feed inlet 2. The rotating shaft 5 is controlled by the motor 7, which in turn drives the mixing rod 6 to rotate, thus mixing the raw materials inside the mixing tank 1. The rotating shaft 5, via the connecting rod 9, drives the vertical scraper 10 to scrape against the mixing tank 1, preventing the raw materials from adhering to the inside of the mixing tank 1. Simultaneously, it secures the outer casing 15. As the rotating shaft 5 rotates, it drives the linkage shaft 14 to revolve. After being restricted by the first sprocket 12, the second sprocket 13, driven by the chain, controls the rotation of the linkage shaft 14, thereby controlling the first tumbling action. Leaf 17 and the second agitator leaf 18, since the first agitator leaf 17 and the second agitator leaf 18 are in opposite directions, break the axial and radial flow of raw materials and improve the mixing efficiency of raw materials inside the mixing tank 1. After the pour point depressant is synthesized, the discharge pipe 3 is opened by the control valve 4 and the pour point depressant is discharged from the mixing tank 1 through the discharge pipe 3. The rotating shaft 5 controls the vertical scraper 10 to rotate, and at the same time the rotating shaft 5 drives the horizontal scraper 8 to rotate, scraping the bottom of the mixing tank 1 and cleaning the remaining pour point depressant inside the mixing tank 1, thereby increasing the amount of pour point depressant produced and reducing the difficulty of cleaning the mixing tank 1, thus improving the production efficiency of the pour point depressant.
