Description

Technical Field

[0001] This utility model relates to the technical field of lubricating oil production equipment, and in particular to a stirring device for a lubricating oil production reactor. Background Technology

[0002] Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. Its main functions include lubrication, auxiliary cooling, rust prevention, cleaning, sealing, and buffering. Any lubricating oil that reduces friction and wear between two relatively moving objects is considered lubricating oil.

[0003] A serious problem with existing lubricating oil stirring devices is that they can only stir the lubricating oil laterally, causing the lubricating oil to gradually separate into layers, thus affecting the quality of the lubricating oil. Utility Model Content

[0004] Therefore, it is necessary to provide a stirring device for a lubricating oil production reactor to address the problem that the poor fluidity and low viscosity of existing lubricating oils easily lead to uneven mixing or stratification, thus affecting the quality and performance of the lubricating oil.

[0005] A stirring device for a lubricating oil production reactor, comprising: Fixture, A rotating shaft, which is rotatably connected to the fixed frame; A drive mechanism is provided, which is mounted on the fixed frame, and the rotating shaft is connected to the drive mechanism in a transmission manner. An upper stirring paddle is fitted onto the uppermost end of the rotating shaft. The upper stirring paddle includes an upper fixing member and an upper blade connected to the upper fixing member. The upper blade is inclined relative to the axis of the rotating shaft. A lower agitator, fitted onto the lowest end of the rotating shaft, includes a lower fixing member and a lower blade connected to the lower fixing member. The lower blade is inclined relative to the axis of the rotating shaft, and the inclination direction of the lower blade is opposite to that of the upper blade. The middle agitator is fitted outside the rotating shaft and is located between the upper agitator and the lower agitator. The middle agitator includes a middle fixing member and a main blade connected to the middle fixing member. The main blade is inclined relative to the axis of the rotating shaft, and the inclination direction of the main blade is the same as that of the upper blade. The upper blade, the main blade, and the lower blade are spaced apart circumferentially along the rotating shaft.

[0006] The aforementioned stirring device for the lubricating oil production reactor has an upper impeller, a main impeller, and a lower impeller all inclined relative to the axis of the rotating shaft. The lower impeller is inclined in the opposite direction to the upper impeller, while the main impeller is inclined in the same direction as the upper impeller. The upper impeller, the main impeller, and the lower impeller are spaced apart circumferentially along the rotating shaft. During rotation, the upper and main impellers drive the high-viscosity lubricating oil material downwards for mixing, pushing the material to flow strongly radially. Meanwhile, the lower impeller scoops up the high-viscosity lubricating oil material from the bottom of the reactor, pushing the material to flow strongly radially, preventing the material from settling at the bottom of the reactor due to its high viscosity. This ensures uniform mixing of the material, effectively improving production quality and efficiency.

[0007] In one embodiment, the angles formed by the upper blade and the axis of rotation, the main blade and the axis of rotation, and the lower blade and the axis of rotation are all 45°.

[0008] In one embodiment, the upper fixing member includes a clamping connector, an upper mounting plate connected to the clamping connector, and an upper shearing plate connected to the upper mounting plate. The upper blade is fixedly connected to the upper mounting plate, and the upper shearing plate is disposed at the upper end of the upper mounting plate and is perpendicular to the axis of the rotating shaft.

[0009] In one embodiment, the lower fixing member includes a clamping connector, a lower mounting plate connected to the clamping connector, and a lower shearing plate connected to the lower mounting plate. The lower blade is fixedly connected to the lower mounting plate, and the lower shearing plate is disposed at the lower end of the lower mounting plate. The lower shearing plate is perpendicular to the axis of the rotating shaft.

[0010] In one embodiment, there are multiple intermediate stirring blades, which are arranged sequentially along the rotation axis, and multiple main blades are arranged circumferentially around the rotation axis.

[0011] In one embodiment, the fixing member includes a clamp connector and a mounting rod connected to the clamp connector. The mounting rod is integrally connected to a mounting block. The main blade is provided with limit strips. There are two limit strips, and a limit groove is formed between the two limit strips. The mounting block is inserted into the limit groove. The main blade is fixedly connected to the mounting block by screwing.

[0012] In one embodiment, the upper blade and the main blade are provided with downward-curved hooks.

[0013] In one embodiment, the lower blade is provided with an upward-curved hook.

[0014] In one embodiment, the drive mechanism includes a drive motor, a reducer, and a clamping shaft coupling. The rotating shaft is connected to the reducer via the clamping shaft coupling, and the reducer is drive-connected to the drive motor.

[0015] In one embodiment, the drive mechanism further includes a drive wheel, a transmission wheel, and a transmission belt. The drive wheel is driven by the drive motor, the transmission wheel is driven by the reducer, and the transmission wheel is driven by the drive wheel via the transmission belt.

[0024] Please see Figure 1 A stirring device 100 for a lubricating oil production reactor, according to one embodiment of the present invention, includes a fixed frame 10, a rotating shaft 20, a drive mechanism 30, an upper stirring paddle 40, a lower stirring paddle 50, and a middle stirring paddle 60. The rotating shaft 20 is rotatably connected to the fixed frame 10. The drive mechanism 30 is disposed on the fixed frame 10 and is drively connected to the rotating shaft 20. The upper stirring paddle 40 is fitted onto the uppermost end of the rotating shaft 20, the lower stirring paddle 50 is fitted onto the lowermost end of the rotating shaft 20, and the middle stirring paddle 60 is fitted onto the outside of the rotating shaft 20 and is disposed between the upper stirring paddle 40 and the lower stirring paddle 50.

[0025] Please see Figure 2 The drive mechanism 30 includes a drive motor 31, a reducer 32, and a clamping shaft coupling 33. The rotating shaft 20 is connected to the reducer 32 through the clamping shaft coupling 33, and the reducer 32 is connected to the drive motor 31 in a transmission connection.

[0026] Please see Figure 2 The drive mechanism 30 further includes a drive wheel 34, a transmission wheel 35, and a transmission belt 36. The drive wheel 34 is connected to the drive motor 31, the transmission wheel 35 is connected to the reducer 32, and the transmission wheel 35 is connected to the drive wheel 34 via the transmission belt 36.

[0027] Please see Figure 2The upper stirring paddle 40 includes an upper fixing member 41 and an upper blade 42 connected to the upper fixing member 41. The upper fixing member 41 includes a clamping connector 411, an upper mounting plate 412 connected to the clamping connector 411, and an upper shearing plate 413 connected to the upper mounting plate 412. The upper blade 42 is fixedly connected to the upper mounting plate 412 and is inclined relative to the axis of the rotating shaft 20. The angle between the upper blade 42 and the axis of the rotating shaft 20 is 45°, which can generate axial and radial flow simultaneously during rotation, effectively making the material mix more uniform and improving production quality. Moreover, the resultant torque of the upper blade 42 rotating around the rotating shaft 20 is minimized, which can effectively reduce the stress load on the upper blade 42 and improve operating efficiency and stability. The upper blade 42 is equipped with a downward-curved hook 421, which drives the high-viscosity lubricating oil material downward during rotation, promoting a strong radial flow of the material and effectively improving the quality of lubricating oil production. The upper shear plate 413 is located at the upper end of the upper mounting plate 412, and the upper shear plate 413 is perpendicular to the axis of the rotating shaft 20. The upper shear plate 413 can effectively disperse additive agglomerates, avoiding particulate impurities or performance fluctuations in the finished lubricating oil.

[0028] Please see Figure 3 The lower stirring paddle 50 includes a lower fixing member 51 and a lower impeller 52 connected to the lower fixing member 51. The lower fixing member 51 includes a clamping connector 511, a lower mounting plate 512 connected to the clamping connector 511, and a lower shearing plate 513 connected to the lower mounting plate 512. The lower impeller 52 is fixedly connected to the lower mounting plate 512. The lower impeller 52 is inclined relative to the axis of the rotating shaft 20, and the angle between the lower impeller 52 and the axis of the rotating shaft 20 is 45°. This allows for the simultaneous generation of axial and radial flow during rotation, effectively making the material mix more uniform and improving production quality. Moreover, the resultant torque of the lower impeller 52 rotating around the rotating shaft 20 is minimized, effectively reducing the stress load on the upper impeller 42 and improving operating efficiency and stability. The lower blade 52 is tilted in the opposite direction to the upper blade 42. The lower blade 52 has an upward-curving hook 521, which allows it to scoop up high-viscosity lubricating oil from the bottom of the vessel during rotation, propelling the material to flow strongly radially. This prevents the material from settling at the bottom due to its high viscosity, effectively improving the quality of lubricating oil production. The lower shear plate 513 is located at the lower end of the lower mounting plate 512, and is perpendicular to the axis of the rotating shaft 20. The lower shear plate 513 effectively breaks up deposits and agglomerates, preventing uneven mixing in certain areas.

[0029] Please see Figure 2The number of the intermediate stirring paddles 60 is multiple, and the multiple intermediate stirring paddles 60 are arranged sequentially along the direction of the rotation axis 20. Each intermediate stirring paddle 60 includes an intermediate fixing member 61 and a main blade 62 connected to the intermediate fixing member 61. The intermediate fixing member 61 includes a clamping connector 611 and a mounting rod 612 connected to the clamping connector 611. The mounting rod 612 is integrally connected to a mounting block 613. The main blade 62 is provided with limit strips 621. There are two limit strips 621, and a limit groove 622 is formed between the two limit strips 621. The mounting block 613 is inserted into the limit groove 622. The main blade 62 is fixedly connected to the mounting block 613 by screwing. The main blade 62 is inclined relative to the axis of the rotation shaft 20, and the angle between the main blade 62 and the axis of the rotation shaft 20 is 45°. The inclination direction of the main blade 62 is the same as that of the upper blade 42. The main blade 62 is provided with a downwardly hooked lower arc 623. The upper blade 42, the main blade 62, and the lower blade 52 are arranged circumferentially around the rotation shaft 20. Multiple main blades 62 are arranged circumferentially around the rotation shaft 20. This effectively improves mixing efficiency and production efficiency.

[0030] The working principle of the stirring device 100 for the lubricating oil production reactor in this embodiment is as follows: The drive motor 31 drives the rotating shaft 20 to rotate. Under the drive of the rotating shaft 20, the upper stirring blade 40, the lower stirring blade 50 and the middle stirring blade 60 rotate simultaneously. During this process, the upper blade 42 and the main blade 62 drive the high-viscosity lubricating oil material downward to mix, and push the material to flow strongly in the radial direction. Meanwhile, the lower blade 52 scoops up the high-viscosity lubricating oil material from the bottom of the reactor and pushes the material to flow strongly in the radial direction, avoiding the material from settling at the bottom of the reactor due to its high viscosity. This can make the material mix evenly, effectively improve the production quality and increase the production efficiency.

[0031] The beneficial effects of this utility model are as follows: the upper blade 42, the main blade 62, and the lower blade 52 are all inclined relative to the axis of the rotating shaft 20. The inclination direction of the lower blade 52 is opposite to that of the upper blade 42, and the inclination direction of the main blade 62 is the same as that of the upper blade 42. The upper blade 42, the main blade 62, and the lower blade 52 are arranged circumferentially along the rotating shaft 20. In this way, during the rotation process, the upper blade 42 and the main blade 62 drive the high-viscosity lubricating oil material downward to mix and push the material to flow strongly radially, while the lower blade 52 scoops up the high-viscosity lubricating oil material from the bottom of the vessel and pushes the material to flow strongly radially, avoiding the material from settling at the bottom of the vessel due to its high viscosity. This makes the material mix evenly, effectively improving production quality and production efficiency.

[0032] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0033] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
