It mainly plays the role of lubrication, auxiliary cooling, cleaning, rust prevention, buffering, etc. Lubricating oil is composed of two parts: base oil and additives. Base oil is the main component of lubricating oil and determines the basic properties of lubricating oil. It must meet certain freezing point requirements. The wax component in the base oil will cause its freezing point to increase and its fluidity to decrease. Therefore, the lubricating oil needs to be dewaxed during the production process.

[0033] By setting a stirring device, the lubricating oil to be dewaxed is stirred, the rubber sleeve 21 seals the cooling tank 2 and the cooling plate 52, the driving motor 22 drives the rotating rod 23 to rotate, drives the fixed circular plate 3 to rotate, drives the tooth column 42 fixedly installed with the circular plate 3 to rotate, the outer surface of the rotating rod 23 is rotatably sleeved with the bracket 31, the outer surface of the bracket 31 is fixedly installed with a rotating gear 32 through a bearing, the outer surface of the rotating sleeve of the rotating gear 32 is fixedly installed with the scraper 4, and the rotating gear 32 drives the scraper 4 to rotate while rotating, the inner wall of the cooling tank 2 is fixedly installed with a ring 41 through a support rod, the ring 41 and the outer surface of the circular plate 3 are fixedly installed with a tooth column 42, the tooth column 42 is meshed with the rotating gear 32, so that the scraper 4 revolves and rotates at the same time, which solves the technical problem that when the lubricating oil is continuously frozen and dewaxed, the lubricating oil is cooled only by the cooling coil, and the cooling coil can usually only locally cool the lubricating oil, but cannot achieve an overall uniform cooling effect, resulting in uneven temperature distribution of the lubricating oil in the system.

[0034] In order to cool the lubricating oil, a processing device is provided on the outer surface of the frame 1. The processing device includes a cooling plate 52. The movement of the cooling plate 52 cools the lubricating oil.

[0035] In order to drive the threaded rod 51 to rotate, the processing device also includes a moving motor 5, which is fixedly installed on the outer surface of the frame 1.

When the cooling plate 52 is reset, the push plate pushes the wax crystals on the filter net in the filter tank 7 aside to prevent the wax crystals from clogging the filter net, thereby affecting the filtering effect.

[0037] In order to achieve continuous dewaxing and filtration of lubricating oil, a filter tank 7 with a filter screen is fixedly installed on the outer surface of the frame 1, and the outer surface of the filter screen contacts the outer surface of the push plate. An oil pump 71 is fixedly installed on the outer surface of the frame 1, and the oil inlet end of the oil pump 71 is fixedly connected to the outer surface of the filter tank 7 through an oil inlet pipe, and the oil outlet end of the oil pump 71 is fixedly connected to the outer surface of the cooling tank 2 through an oil outlet pipe. By installing the filter tank 7 with a filter screen, the lubricating oil is filtered, and the filter screen of the filter tank 7 contacts the push plate. When the cooling plate 52 is reset, the push plate pushes the wax crystals on the filter screen in the filter tank 7 aside, and the filter is fixedly connected to the filter tank 7 through the oil inlet pipe of the oil pump 71. After the filtered lubricating oil is sucked, it enters the fixedly connected cooling tank 2 through the oil outlet pipe, and the above operation is repeated to achieve continuous dewaxing and filtration of the lubricating oil.

[0038] By setting up a processing device, the lubricating oil after dewaxing is cooled, the mobile motor 5 drives the threaded rod 51 to rotate, the threaded rod 51 is threadedly connected with the cooling plate 52, the cooling plate 52 is slidably plugged with the cooling tank 2, so that it can only move on the threaded rod 51, the sliding rod 6 supports the cooling plate 52 slidably sleeved therewith, the cooling pipe 61 cools the lubricating oil, the scraper block 62 contacts the cooling plate 52, and when the cooling plate 52 moves outward, the wax crystals on the cooling plate 52 are scraped off, the outer surface of the cooling plate 52 is fixedly installed with a push plate, and the filter screen cools the lubricating oil.

After the filtered lubricating oil is sucked, it enters the fixedly connected cooling tank 2 through the oil outlet pipe, and the above operation is repeated to realize continuous dewaxing and filtration of the lubricating oil. This solves the technical problem that when the lubricating oil is continuously frozen dewaxed, it is only sucked through the oil pipe, and unfiltered wax crystals may enter the oil pipe, causing oil circuit blockage, which not only affects the flow of the lubricating oil.

[0039] Working principle: when the lubricating oil needs to be stirred, the liquid inlet and the liquid outlet of the cooling tube 61 are connected to allow the liquid to circulate in the cooling tube 61 to cool the lubricating oil. At the same time, the driving motor 22 is started to drive the rotating rod 23 to rotate, driving the fixedly installed circular plate 3 to rotate. The rotating rod 23 is externally rotated and sleeved with the bracket 31. The rotating gear 32 fixedly installed on the outside of the bracket 31 through the bearing is meshed with the tooth column 42 on the circular plate 3, so that the rotating gear 32 revolves. At the same time, the rotating gear 32 is meshed with the tooth column 42 on the ring 41 fixedly installed in the cooling tank 2, so that the rotating gear 32 rotates on its own, thereby driving the rotating sleeve of the rotating gear 32 to revolve and rotate while the scraper 4 fixedly installed on it revolves, thereby accelerating the cooling speed of the lubricating oil. The rubber sleeve 21 seals the cooling tank 2 and the cooling plate 52 to prevent the leakage of the lubricating oil.

[0040] When the stirred lubricating oil is processed, the driving motor 22 is turned off and the moving motor 5 is started to drive the threaded rod 51 to rotate, thereby driving the cooling plate 52 threadedly connected to it and slidably plugged into the cooling tank 2 to move, and the sliding rod 6 supports it. The scraper block 62 contacts the cooling plate 52. When the cooling plate 52 moves outward, the wax crystals on the cooling plate 52 are scraped off and fall onto the filter net. At the same time, the lubricating oil enters the filter tank 7 with a filter to filter it. After the filtering is completed, the threaded rod 51 drives the cooling plate 52 to reset. When the cooling plate 52 is reset, the push plate pushes the wax crystals on the filter net in the filter tank 7 aside, and the oil inlet pipe of the oil pump 71 is fixedly connected to the filter tank 7. After the filtered lubricating oil is sucked, it enters the fixedly connected cooling tank 2 through the oil outlet pipe. The above operation is repeated to realize continuous dewaxing and filtration of the lubricating oil.
