A dosimeter is provided at the discharge port of the batching container 25 to control the amount of extreme pressure additives added to the blending tank 1. When extreme pressure additives need to be added, the extreme pressure additives are placed into the batching container and mixed with the base oil in the oil inlet pipe 26 and then placed into the blending tank 1 together.

[0027] A top cover 3 is provided at the top of the blending tank 1. The top cover 3 includes a first cover body 31 integrally formed and fixedly connected to the side wall of the blending tank 1 and a second cover body 32 rotatably connected to the middle of the first cover body 31 through a bearing. A plurality of groups of stirring mechanisms extending into the interior of the blending tank 1 are uniformly connected circumferentially along the axis of the second cover body 32 on the second cover body 32. The stirring mechanisms are rotationally matched with the second cover body 32. A driving mechanism for driving the second cover body 32 to rotate is provided at the top of the blending tank 1. A power mechanism for driving the stirring mechanisms to rotate is provided between the stirring mechanisms and the driving mechanism. In this embodiment, there are two groups of stirring mechanisms, and the two groups of stirring mechanisms are symmetrically arranged about the axis of the second cover body 32, and the two groups of stirring mechanisms are diverging from top to bottom.

[0028] A housing 2 is fixedly installed at the top of the second cover body 32. The bottom end of the housing 2 is open and a cavity is provided inside the housing 2. An installation box 6 is provided above the housing 2 at the top of the blending tank 1, and an installation cavity is provided inside the installation box 6. In this embodiment, an L-shaped bracket 14 is provided at the top of the first cover body 31, and the two ends of the bracket 14 are respectively fixedly connected to the side wall of the first cover body 31 and the installation box 6 to provide stable support for the installation box 6. The driving mechanism includes a motor 7 and a sleeve 8. The motor 7 is fixedly installed on one side of the installation cavity of the installation box 6 through bolts. The sleeve 8 is vertically arranged. The motor 7 is connected to the sleeve 8 through a gear transmission. The top end of the sleeve 8 is located inside the installation cavity, and the bottom end penetrates through the bottom wall of the installation box 6 and is fixedly connected to the top wall of the housing 2. In this embodiment, the sleeve 8 is rotatably installed on the bottom wall of the installation box 6 through a bearing. A first gear 10 is fixedly sleeved on the part of the sleeve 8 located inside the installation cavity. The output end of the motor 7 is fixedly connected to a second gear 11 meshing with the first gear 10. When the motor 7 rotates, the sleeve 8 can be driven to rotate, and the sleeve 8 rotates to drive the housing 2 and the second cover body 32 to rotate.

[0029] The power mechanism includes a fixed shaft 9. The top end of the fixed shaft 9 is fixedly connected to the top wall of the installation box 6, and the bottom end sequentially passes through the sleeve 8 and the top wall of the housing 2 and is located inside the housing 2. The fixed shaft 9 is rotatably fitted with both the sleeve 8 and the housing 2. In fact, the fixed shaft 9 can be rotatably connected to the sleeve 8 and the top wall of the housing 2 through bearings respectively. In this embodiment, the fixed shaft 9 does not contact the sleeve 8 and the top wall of the housing 2, with a simple structure and low cost.

[0030] The central axes of the fixed shaft 9, the sleeve 8, the second cover 32, and the housing 2 are collinear, making the operation of this solution stable and easier to implement.

[0031] The stirring mechanism includes a rotating shaft 15. The top end of the rotating shaft 15 passes through the bottom wall of the second cover 32 and is inclined in the cavity of the housing 2, and the bottom end passes through the second cover 32 and extends into the mixing tank 1. In this embodiment, the rotating shaft 15 is inclined downward and away from the central axis of the second cover 32 from top to bottom, so that the two rotating shafts 15 can cover the internal space of the mixing tank 1 as much as possible to avoid dead corners in the tank. The rotating shaft 15 is rotatably connected to the second cover 32 through a bearing. A guiding gear 12 is fixedly sleeved on the part of the fixed shaft 9 located in the cavity of the housing 2, and a driving gear 13 is fixedly sleeved on the part of the rotating shaft 15 located in the housing 2. The guiding gear 12 is in transmission connection with the driving gear 13. In this embodiment, both the guiding gear 12 and the driving gear 13 are bevel gears, which are convenient for installation and transmission.

[0032] One end surface of the rotating shaft 15 located in the mixing tank 1 is fixedly provided with stirring blades 16. In this embodiment, two sets of stirring groups are symmetrically arranged along the circumferential direction of the rotating shaft 15. Each set of stirring groups includes a number of stirring blades 16 spaced along the axial direction of the rotating shaft 15. The stirring blades 16 of the two sets of stirring groups are staggered. Each stirring blade 16 is provided with an oval through hole 23. With the oval through holes 23 on the stirring blades 16, the resistance during the stirring process of the stirring blades 16 is small, and the lubricating oil can pass through the oval through holes 23 during the stirring process, making the stirring more uniform and the stirring effect better. A first scraping plate 17 for scraping the bottom wall of the mixing tank 1 is provided at the bottom end of the stirring shaft. In this embodiment, the first scraping plate 17 includes a vertical plate and a horizontal plate. There are two horizontal plates, and the two horizontal plates are integrally formed and installed at both ends of the bottom of the vertical plate respectively, and the two horizontal plates are located on both sides of the vertical plate respectively. The horizontal plates are used to fit the bottom wall of the mixing tank 1. The vertical plate of the first scraping plate 17 is installed at the bottom end of the rotating shaft 15 through bolts, which is convenient for maintaining and replacing the first scraping plate 17. The first scraping plate 17 is inclined to cooperate with the conical discharge port of the mixing tank 1. With such a structural design, when the rotating shaft 15 rotates, the materials in the mixing tank 1 are fully stirred by the stirring blades 16, and at the same time, the first scraping plate 17 scrapes the inner wall of the conical discharge port of the mixing tank 1 to scrape the solid oil slag deposited at the bottom of the mixing tank 1 into the discharge pipe 5, avoiding the blockage of the discharge port and the phenomenon of "sticking to the pot", which can improve the production efficiency of the extreme pressure lubricating oil and also improve the production quality of the extreme pressure lubricating oil, with good use effect.

[0033] A scraping component for scraping the side wall of the blending tank 1 is provided on the housing 2. The scraping component includes a connecting rod 18 and a second scraper 20. The top end of the connecting rod 18 is fixedly installed on the side wall of the housing 2, and the bottom end penetrates through the second cover 32 and extends into the blending tank 1. The second scraper 20 is installed on the part of the connecting rod 18 located in the blending tank 1. The second scraper 20 is used to contact the side wall of the blending tank 1. In this embodiment, there are two sets of scraping components, and the two sets of scraping components are symmetrically arranged on two opposite side walls of the housing 2. A cross bar 19 is provided between the second scraper 20 and the connecting rod 18 to facilitate the installation and support of the scraper. Multiple cross bars 19 can be arranged at intervals along the vertical direction as needed. At the same time, the connecting rod 18 and the cross bar 19 can also play a certain stirring role on the material, further making the mixing of the material more uniform.

[0034] In the above embodiment, the first scraper 17 and the second scraper 20 can perform all-round scraping and cleaning on the bottom wall and side wall of the blending tank 1, avoiding the adhesion of impurities such as squeezed lubricating oil and oil residues on the inner wall of the blending tank 1, making there be no dead corners in the blending tank 1 and ensuring sufficient stirring; a through hole 21 for the rotation shaft 15 to pass through and a through hole 22 for the connecting rod 18 to pass through are provided on the second cover 32. The two through holes 22 and the two through holes 21 are arranged in a rectangular distribution.

[0035] In the above embodiment, during the production process, the blending tank 1 is usually heated as needed. The heating method can adopt the heating method of the existing technology, such as setting an electric heating wire or an electric heating plate in the side wall of the blending tank 1, or surrounding a heating water pipe around the outer wall of the blending tank 1.

[0036] Working principle:

[0037] Base oil and extrusion additives are added into the blending tank 1 through the feed pipe 4. The motor 7 is started. The rotation of the motor 7 drives the sleeve 8, the housing 2, and the second cover 32 to rotate. At the same time, the housing 2 drives the connecting rod 18 to rotate, and the second cover 32 drives the rotation shaft 15 to rotate. The rotation of the connecting rod 18 drives the cross bar 19 and the second scraper 20 to rotate. The part of the connecting rod 18 located in the blending tank 1 and the cross bar 19 have a certain stirring effect on the material, and the second scraper 20 performs scraping and cleaning on the side wall of the blending tank 1; while the rotation shaft 15 revolves around the central axis of the second cover 32, the driving gear 13 rotates around the guiding gear 12, causing the rotation shaft 15 to rotate self - rotatably. That is to say, the rotation shaft 15 revolves around the central axis of the second cover 32 while rotating self - rotatably. The stirring blades 16 fully stir the material in the blending tank 1, and the rotation shaft 15 also drives the first scraper 17 to perform wall - hanging cleaning on the bottom wall of the blending tank 1, realizing all - round and dead - corner - free mixing and stirring inside the blending tank 1, with good stirring effect and improving the quality of the extreme pressure lubricating oil. Finally, the stirred extrusion lubricating oil is discharged through the discharge pipe 5, and the next process can be carried out.
