Description

Technical Field

[0001] This utility model relates to the field of multi-stage filtration anti-wear lubricating oil technology, and in particular to a multi-stage filtration anti-wear lubricating oil device for ultra-long mills. Background Technology

[0002] Lubricating oil, a key lubricant used in various automobiles and mechanical equipment, exists in liquid or semi-solid form and can effectively reduce frictional losses between mechanical parts, providing comprehensive protection for equipment. Its core functions cover multiple dimensions: in terms of lubrication, it reduces the coefficient of friction and wear by forming an oil film on the friction surface; its auxiliary cooling function can promptly remove the heat generated by friction, preventing parts from deforming due to high temperatures; its rust-preventing performance inhibits oxidation and rust by isolating air from contact with metal; its cleaning function can wash away and absorb impurities such as metal shavings and dust; its sealing effect can fill gaps between parts to prevent gas or liquid leakage; and its buffering function helps absorb impact loads during mechanical operation.

[0003] Patent publication number "CN222885546U" discloses "A Multi-Stage Filtration Device for Lubricating Oil," comprising a treatment tank and a primary, secondary, and tertiary filter cartridge located within the treatment tank. A connecting pipe is rotatably mounted at the bottom of the treatment tank. The primary, secondary, and tertiary filter cartridges are all fixedly fitted onto the outer wall of the connecting pipe. A motor driving the connecting pipe is installed on the outer wall of the treatment tank. Three scraper strips are fixedly mounted on the inner top wall of the treatment tank, respectively contacting the inner walls of the primary, secondary, and tertiary filter cartridges. This system allows the lubricating oil to undergo step-by-step filtration, effectively removing impurities and ensuring a purer final discharge. Centrifugal force is also utilized to enhance the filtration effect, allowing the lubricating oil to flow faster through the filter cartridges and accelerating impurity separation, thereby improving the efficiency of the entire filtration system.

[0004] After filtration is completed and the lubricating oil is discharged from the oil outlet pipe, the device in the aforementioned patent opens the first-stage control valve, the second-stage control valve, and the third-stage control valve. Impurities in the first-stage, second-stage, and third-stage filter cartridges will enter the connecting pipe and be discharged through the discharge pipe, facilitating the cleaning of the filtered impurities. If the impurities have viscous properties, they may easily adhere to the inner wall of the connecting pipe and cannot be completely discharged by gravity alone. Over time, if impurities with viscous properties continue to accumulate and adsorb, it is very likely to cause pipeline blockage and affect discharge efficiency. Utility Model Content

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Example

[0029] Reference Figures 1 to 6This is the first embodiment of the present utility model.

[0030] Specifically, the rotating mechanism 4 includes a servo motor 41 and a drive wheel 42. The top of the drive wheel 42 is fixedly installed at the output end of the servo motor 41. A driven wheel 43 is meshed on one side of the drive wheel 42.

The bottom of the drive wheel 42 is rotatably connected to the surface of the can cover 2. The outer side of the top of the rotating tube 31 of the filter mechanism 3 is rotatably connected to the bottom surface of the can cover 2 and penetrates the surface. A detachable first electric valve 5 is fixedly installed at the bottom of the discharge port 37.

[0031] Furthermore, the filtration mechanism 3, through the rotating tube 31, can drive the filter cylinders 35 installed on the outside to rotate for centrifugal multi-stage filtration. The filtered lubricating oil falls into the bottom wall of the tank 1 in an orderly manner. Then, the intercepted impurities are scraped off by the scrapers 36 attached to the inner wall of one side of the filter cylinder 35. Then, the servo electric push rod 32 pulls the block 33 upward, and the impurities will enter the rotating tube 31 through the slot 34 in an orderly manner and fall into the discharge port 37. The detachable first electric valve 5 installed at the bottom of the discharge port 37 is opened and discharged in an orderly manner. When the rotating tube 31 rotates, the scraper 38 attached to its inner wall can scrape off viscous impurities, ensuring that the impurities attached to the inner wall of the rotating tube 31 fall and are discharged smoothly.

[0032] The rotating mechanism 4 can effectively drive the active wheel 42 installed at the output end to rotate through the servo motor 41.

Example

[0033] Reference Figures 1 to 6 This is the first embodiment of the present invention. Based on the previous embodiment, the circulation mechanism 6 includes an outlet 61. The outlet 61 is respectively opened on the bottom wall of the tank 1 and penetrates the bottom surface. An annular pipe 62 is fixedly installed at the bottom end of the outlet 61. A circulation pipe 63 penetrating the inner wall of one side is fixedly installed on one side of the annular pipe 62. A second electric valve 64 penetrating the inner wall of the bottom side is fixedly installed on the bottom side of the circulation pipe 63. A circulation pump 65 penetrating the inner wall of one side is fixedly installed on one side of the top of the circulation pipe 63. The top end of the circulation pipe 63 is fixedly installed on the surface of the tank cover 2 and penetrates the bottom surface.

[0034] Specifically, the circulation pump 65 of the circulation mechanism 6 is fixedly installed on the bottom side of the tank cover 2, and the top port of the circulation pipe 63 is located above the filter cylinder 35 of the filter mechanism 3.

[0035] Furthermore, the lubricating oil filtered by the circulation mechanism 6 flows into the annular pipe 62 through the outlet 61. Then, the second electric valve 64, which penetrates the inner wall of the bottom side of the circulation pipe 63, is opened, allowing the oil to be discharged in an orderly manner to the next processing stage. If further filtration is required, the circulation pump 65 will draw the lubricating oil from the outlet 61 through the annular pipe 62 into the circulation pipe 63. Under its continuous action, the lubricating oil can re-enter the filtration mechanism 3 and achieve further fine filtration through centrifugal force and other actions, ensuring that the oil cleanliness meets the standards.

[0036] Working principle: The rotating mechanism 4 can effectively drive the active wheel 42 installed at the output end to rotate through the servo motor 41. The rotating active wheel 42 can drive the driven wheel 43 meshing on one side to rotate. The rotating driven wheel 43 can drive the rotating tube 31 to rotate synchronously. When the rotating tube 31 drives the filter cylinders 35 installed on the outside to rotate with it, the lubricating oil to be filtered achieves multi-stage filtration under the action of centrifugal force, effectively improving filtration efficiency and accuracy.

[0037] The filtration mechanism 3 drives the externally mounted filter cylinders 35 to rotate via the rotating tube 31 for centrifugal multi-stage filtration. The filtered lubricating oil falls into the bottom wall of the tank 1 in an orderly manner. The intercepted impurities are scraped off by scrapers 36 attached to the inner wall of one side of the filter cylinder 35. Then, the servo electric push rod 32 pulls the block 33 upward, and the impurities are orderly entered into the rotating tube 31 through the slot 34 and fall into the discharge port 37. The detachable first electric valve 5 installed at the bottom of the discharge port 37 is opened and discharged in an orderly manner. When the rotating tube 31 rotates, the scraper 38 attached to its inner wall can scrape off viscous impurities, ensuring that the impurities attached to the inner wall of the rotating tube 31 fall and are discharged smoothly. The top of the filter cylinders 35 is rotatably connected to the bottom surface of the tank cover 2.

[0038] The lubricating oil filtered by the circulation mechanism 6 flows into the annular pipe 62 through the outlet 61. Then, the second electric valve 64, which penetrates the inner wall of the bottom side of the circulation pipe 63, is opened, allowing the oil to be discharged in an orderly manner to the next processing stage. If further filtration is required, the circulation pump 65 will draw the lubricating oil from the outlet 61 through the annular pipe 62 into the circulation pipe 63. Under its continuous action, the lubricating oil can re-enter the filtration mechanism 3 and achieve further fine filtration through centrifugal force and other actions, ensuring that the oil cleanliness meets the standards.
