[0002] Lubricating oil is an oily liquid used to reduce friction and wear between two contact surfaces. It is usually composed of base oil and additives, and has the functions of lubrication, cooling, rust prevention, cleaning, sealing and buffering.

[0003] Base oil is the main component of lubricating oil, which can come from mineral oil, synthetic oil or bio-based oil. Additives are used to improve the performance of lubricating oil, such as antioxidants, anti-wear agents, detergents and dispersants, rust inhibitors, etc. In the production process of lubricating oil, the base oil and additives need to be stirred and mixed to form a whole lubricating oil. During long-term use observation, it is found that existing lubricating oils usually use equipment such as stirring tanks or stirring kettles, and the base oil and additives are continuously stirred and blended by a stirring rod. After the stirring is completed, there will be lubricating oil remaining in the container, and the container is usually a sealed device, which makes it difficult to clean the lubricant remaining inside.

At this time, the first motor 11 can be started to drive the rotating shaft 13, the stirring rod 14 and the water pipe 15 to rotate. At this time, the dynamic sealing structure 17 separates the water pipe 15 from the water inlet pipe 18, which will make the water inlet pipe 18 fixed. When the staggered stirring rods 14 drive the water outlet pipe 16 to rotate, the cleaning liquid will be evenly sprayed inside the mixing tank 1, and then the cleaned sewage will be discharged through the discharge pipe 110. Through the above structure, the water inlet pipe 18 is set to connect the dynamic sealing structure 17, the water pipe 15 and the multiple water outlet pipes 16, which can facilitate the cleaning of the inside of the mixing tank 1, so as to reduce the residual lubricating oil in the mixing tank 1 and improve the convenience of cleaning the mixing tank 1.

[0020] like Figure 2 As shown, a gear ring 2 is fixedly connected to the side wall of the rotating shaft 13, and a pair of rotating rods 21 are rotatably connected to the top of the inner wall of the mixing tank 1. A gear 22 is fixedly connected to the middle of the rotating rod 21, and the gear 22 and the gear ring 2 are meshed with each other. A turbine 23 is fixedly connected to the bottom of the rotating rod 21. During operation, when the lubricating oil is stirred, the rotation of the rotating shaft 13 will drive the gear ring 2 to rotate. At this time, the gear ring 2 will drive the gears 22, the rotating rod 21 and the turbine 23 on both sides to rotate. At this time, the turbine 23 is eccentric to the rotating shaft 13, which can generate vortices in the liquid, thereby disrupting the flow direction of the liquid. Through the above structure, the gear ring 2 is arranged to connect the rotating shaft 13, and the gear ring 2, the rotating rod 21, the gear 22, and the turbine 23 are used in combination, so that vortices can be generated in the lubricating oil during stirring, thereby disrupting the flow direction of the lubricating oil during stirring, so as to improve the uniformity of mixing the additives in the lubricating oil and the base oil.

[0021] like Figure 1 and Figure 4As shown, a feeding pipe 3 is fixedly connected to the top of the mixing tank 1, a second motor 31 is fixedly connected to the end of the feeding pipe 3, an auger 32 is fixedly connected to the output end of the second motor 31, a discharge port 33 is provided at the bottom of the feeding pipe 3, the discharge port 33 is communicated with the feed port 12, a feed pipe 34 is fixedly connected to the top of the feeding pipe 3, when working, the base oil and additives are added to the feeding pipe 3 from the feed pipe 34, and then the second motor 31 is started to drive the auger 32 to rotate, so that the added liquid can be discharged downward. The material is transported through the material port 33, thereby entering the mixing tank 1 from the feed port 12. When transporting in the feed pipe 3, the auger 32 will stir the liquid for pre-mixing. Through the above structure, the feed pipe 3 is set to connect the second motor 31 and the auger 32, the feed port 33, and the feed pipe 34. When adding base oil and additives, they can be pre-mixed to reduce the stirring time of the lubricating oil in the mixing tank 1, and the auger 32 will transport the material evenly to improve the uniformity of the feed in the mixing tank 1.

[0022] like Figure 5 As shown, the connection assembly includes a plurality of fixed blocks 4, and the plurality of fixed blocks 4 are evenly fixed to the bottom of the mixing tank 1. A damping spring 41 is fixed to the bottom of the fixed block 4, and the damping spring 41 is fixed to the top of the leg 19. A plurality of hydraulic dampers 42 are hinged to the side wall of the fixed block 4, and the bottom of the hydraulic damper 42 is hinged to the top of the leg 19. When working, more vibrations will be generated when the lubricating oil is stirred. At this time, the damping spring 41 will shrink and rebound to reduce vibration. When the damping spring 41 shrinks, it will drive the fixed block 4 to descend, thereby squeezing the hydraulic damper. The damper 42 contracts, and when the damping spring 41 rebounds, the fixed block 4 is driven to rise, thereby pulling the hydraulic damper 42 to stretch. At this time, the hydraulic damper 42 contracts and stretches with the damping spring 41, which can reduce the speed of contraction and rebound of the damping spring 41. Through the above structure, the fixed block 4, the damping spring 41 and the hydraulic damper 42 are set, and vibration can be reduced during stirring to reduce the loosening of the connection structure caused by vibration. At the same time, the hydraulic damper 42 can reduce the bouncing caused by the fast contraction and rebound speed of the damping spring 41.

[0023] like Figure 2 As shown, a pair of scrapers 5 are fixedly connected to the side wall of the rotating shaft 13, and the pair of scrapers 5 are symmetrically distributed. During operation, when the rotating shaft 13 rotates, the scrapers 5 will be driven to rotate. At this time, the scrapers 5 will scrape the inner wall of the stirring tank 1. When stirring, the adhesion of lubricating oil to the inner wall of the stirring tank 1 can be reduced. When cleaning, the scraping can be used to improve the cleaning effect of the inner wall of the stirring tank 1. Through the above structure, the scrapers 5 are arranged to reduce the lubricating oil remaining on the inner wall of the stirring tank 1 during stirring and cleaning, so as to improve the collection rate of the lubricating oil and the cleanliness of the cleaning.

[0024] like Figure 3As shown, a slot 6 is provided at the end of the stirring rod 14, and a dispersion plate 61 is fixedly connected to the slot 6. During operation, when the cleaning liquid is sprayed out from the water outlet pipe 16, it will pass through the dispersion plate 61. At this time, the multiple holes in the middle of the dispersion plate 61 will disperse the cleaning liquid and disperse the cleaning liquid into smaller liquids. Through the above structure, the dispersion plate 61 can be set to disperse the cleaning liquid sprayed out of the water outlet pipe 16 to increase the contact range between the cleaning liquid and the inside of the stirring tank 1, thereby improving the cleaning effect.

[0025] like Figure 2 As shown, a rubber layer is sprayed on the surface of the scraper 5. Through the above structure, the rubber layer is arranged on the surface of the scraper 5, which can reduce the corrosion of the scraper 5 by the lubricating oil, and at the same time can increase the friction between the scraper 5 and the inner wall of the stirring tank 1, thereby improving the scraping effect on the inner wall of the stirring tank 1.

[0026] Working principle: add base oil and additives into the mixing tank 1 from the feed port 12, then start the first motor 11 to drive the rotating shaft 13 and the stirring rod 14 to rotate, mix the liquid in the mixing tank 1, and discharge the lubricating oil through the discharge pipe 110 after the mixing is completed, then connect the external cleaning liquid to the water inlet pipe 18 through the water pump, and then send the cleaning liquid into the dynamic sealing structure 17 and the water guide pipe 15 through the water inlet pipe 18, and then divide it from the water guide pipe 15 into multiple water outlet pipes 16. At this time, the first motor 11 can be started to drive the rotating shaft 13, the stirring rod 14 and the water guide pipe 15 to rotate. At this time, the dynamic seal The sealing structure 17 separates the water guide pipe 15 from the water inlet pipe 18, which will keep the water inlet pipe 18 in a fixed state. When the staggered stirring rods 14 drive the water outlet pipe 16 to rotate, the cleaning liquid will be evenly sprayed inside the stirring tank 1, and then the cleaned sewage will be discharged through the discharge pipe 110. When the lubricating oil is stirred, the rotation of the rotating shaft 13 will drive the gear ring 2 to rotate. At this time, the gear ring 2 will drive the gears 22, the rotating rod 21 and the turbine 23 on both sides to rotate. At this time, the turbine 23 is eccentric with the rotating shaft 13, which can generate vortexes in the liquid, thereby disrupting the flow direction of the liquid. When adding materials, the basic The oil and additives are added into the delivery pipe 3 from the feed pipe 34, and then the second motor 31 is started to drive the auger 32 to rotate, so that the added liquid can be delivered to the lower feed port 33, and then enter the mixing tank 1 from the feed port 12. When being delivered in the delivery pipe 3, the auger 32 will stir the liquid for pre-mixing, and more vibration will be generated when the lubricating oil is stirred. At this time, the damping spring 41 will shrink and rebound to reduce vibration. When the damping spring 41 shrinks, it will drive the fixed block 4 to descend, thereby squeezing the hydraulic damper 42 to shrink. When the damping spring 41 rebounds, it will drive the fixed block 4 to rise, thereby pulling the liquid The hydraulic damper 42 is stretched, and the hydraulic damper 42 contracts and stretches along with the damping spring 41, which can reduce the speed of contraction and rebound of the damping spring 41. When the rotating shaft 13 rotates, the scraper 5 is driven to rotate. At this time, the scraper 5 scrapes the inner wall of the mixing tank 1, which can reduce the adhesion of lubricating oil to the inner wall of the mixing tank 1 during stirring. When cleaning, the scraping can be used to improve the cleaning effect of the inner wall of the mixing tank 1. When the cleaning liquid is sprayed out from the water outlet pipe 16, it will pass through the dispersion plate 61. At this time, the multiple holes in the middle of the dispersion plate 61 will disperse the cleaning liquid and disperse the cleaning liquid into smaller liquids.
