Description

Technical Field

[0001] This utility model relates to the field of lubricating oil processing technology, and in particular to a lubricating oil filtration device. Background Technology

[0002] Lubricating oil is a liquid or semi-solid substance used to reduce friction between mechanical parts, reduce wear, cool down, clean impurities, prevent corrosion, and seal against leaks. It is usually composed of base oil and additives and is widely used in various mechanical equipment such as engines, gearboxes, hydraulic systems, and bearings to ensure their normal operation and extend their service life. During use, lubricating oil can mix with various solid impurities, which can accelerate the wear of mechanical parts and even lead to equipment failure. Filtration can effectively remove these solid impurities, maintain the cleanliness of the lubricating oil, and thus reduce wear and the risk of failure.

[0003] A search revealed that Chinese Patent CN222358053U discloses a lubricating oil filtration device. Addressing the issue that existing lubricating oil filtration devices accumulate foreign particles on the filter screen during prolonged use, affecting filtration efficiency, this device addresses this problem. After lubricating oil is injected into the inner filter cartridge, the motor's startup drives the rotating sleeve on the drive screw. A cleaning brush, located on one side of a support frame, moves the sleeve, causing the support frame to rotate and scrape the inner filter cartridge, removing the accumulated foreign particles and ensuring proper lubricating oil filtration. This improves the overall filtration efficiency of the lubricating oil.

[0004] While the aforementioned devices facilitate the friction and scraping of particles adhering to the filter screen, they are not conducive to the removal of impurities after scraping. Although some lubricating oil filtration devices exist on the market, some devices suffer from poor filtration effects and inconvenient impurity cleaning. For example, in some filtration devices, impurities easily clog the filter screen during the filtration process, leading to a decrease in filtration efficiency. Furthermore, cleaning the impurities on the filter screen requires stopping the machine, affecting production progress. Some devices also fail to remove the filtered impurities from the device in a timely and effective manner, causing impurities to accumulate inside the device, which also affects the filtration effect and the normal operation of the equipment.

[0017] 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.

[0018] As attached Figure 1-7 As shown, this utility model provides an embodiment of a lubricating oil filtration device, including a lower filter tank 1, which is cylindrical and has certain strength and corrosion resistance. A higher filter tank 2 is detachably and fixedly connected to its upper surface. The upper filter tank 2 and the lower filter tank 1 together form a closed filtration space. An inlet pipe 3 is connected through the upper surface of the upper filter tank 2. The inlet pipe 3 is used to introduce the lubricating oil to be filtered into the interior of the filtration device. The pipe diameter is designed according to the actual flow requirements. A drain pipe 4 is connected through the bottom of one side of the lower filter tank 1. The function of the drain pipe 4 is to discharge the filtered clean lubricating oil out of the device for subsequent use. A transparent shell 5 is also fixedly connected to one side of the lower filter tank 1. The transparent shell 5 is made of transparent material, such as plexiglass, to facilitate the operator to observe the internal situation. The interior of the lower filter tank 1 is equipped with a slag discharge component for discharging impurities after the lubricating oil is filtered. This slag discharge component is one of the core parts of this device and can effectively clean the impurities generated during the filtration process. The slag discharge assembly includes a filter ring 6, which is circular and fixedly connected inside the filter lower tank 1. The filter ring 6 is usually made of corrosion-resistant material. The filter ring 6 has filter holes for filtering lubricating oil. A shim ring 7 is fixedly connected to the inner wall of the filter ring 6. The shim ring 7 plays the role of raising and supporting. An arc-shaped filter plate 8 is fixedly connected to the upper surface of the shim ring 7. The surface of the arc-shaped filter plate 8 is arc-shaped, which also facilitates the sliding and collection of impurities. As attached Figure 5 As shown, a hydraulic cylinder 9 is fixedly installed on one side of the lower surface of the filter lower barrel 1. The hydraulic cylinder 9 serves as a power source, providing stable thrust and pull. The output end is sealed. A housing 10 is fixedly connected to the other side of the lower surface of the filter lower barrel 1. The housing 10 is a hollow cylinder. An inner column 11 is slidably connected inside the housing 10. The inner column 11 can slide freely up and down within the housing 10, serving as a guide and support. A connecting frame 12 is fixedly connected to the output end of the hydraulic cylinder 9 and one end of the inner column 11. The connecting frame 12 serves to connect and transmit power. A ring frame 13 is fixedly connected to one side of the two connecting frames 12. The ring frame 13 is a circular ring formed by two fixedly connected rings and is located below the filter ring 6. Its size is adapted to the filter ring 6. A multi-rod frame 14 is fixedly connected to the top of the two connecting frames 12. The multi-rod frame 14 is a circular whole composed of multiple rods and is located below the arc-shaped filter plate 8.

[0019] As attached Figure 2As shown, multiple ejector pins 15 are fixedly connected to the upper surfaces of the multi-rod frame 14 and the annular frame 13. The ejector pins 15 are slender and made of a material with high hardness, capable of withstanding a certain pressure. When slag discharge is required, the ejector pins 15 can be pushed upwards under the action of power to push out the impurities in the filter ring 6 and the arc-shaped filter plate 8. The multiple ejector pins 15 below the filter ring 6 are arranged in a ring, while the multiple ejector pins 15 corresponding to the arc-shaped filter plate 8 are arranged in a circle and match the arc surface of the arc-shaped filter plate 8. The middle of the upper surface of the filter upper barrel 2 A variable speed motor 24 is fixedly installed. The variable speed motor 24 can adjust the speed according to actual needs. A rotating shaft 25 is fixedly connected to the output end of the variable speed motor 24. The rotating shaft 25 plays the role of transmitting power. Its material is usually high-strength steel. A scraper 26 is fixedly connected to one end of the rotating shaft 25. The shape of the scraper 26 matches the surface shape of the combined arc surface filter plate 8, the padding ring 7 and the filter ring 6. It can rotate under the drive of the rotating shaft 25 to scrape off impurities on the arc surface filter plate 8 and the filter ring 6.

[0020] As attached Figure 4 As shown, a mounting port 16 is provided on one side of the filter ring 6 to facilitate the installation and removal of the chip collection frame 17.

[0021] As attached Figure 6 As shown, a chip collection frame 17 is slidably connected inside the mounting port 16. The chip collection frame 17 is cuboid in shape and is used to collect falling impurities. It has multiple filter holes inside for filtering lubricating oil. An iron block 18 is fixedly connected to the lower surface of the chip collection frame 17. The iron block 18 has a certain magnetic adsorption capacity. A pull handle 19 is fixedly connected inside the chip collection frame 17. The pull handle 19 makes it convenient for operators to pull the chip collection frame 17 out of the mounting port 16 for cleaning. An L-shaped fixing frame 20 is fixedly connected to one side of the transparent shell 5. The fixing frame 20 serves to fix and support the chip collection frame. A magnet frame 21 is fixedly connected to one end of the fixing frame 20. The iron block 18 is placed inside the magnet frame 21. Through the adsorption between the magnet frame 21 and the iron block 18, the chip collection frame 17 can be stably fixed inside the mounting port 16.

[0022] As attached Figure 2 As shown, a connecting pipe 22 is connected through one side of the transparent shell 5. The connecting pipe 22 is used to open the port to clean the impurities in the chip collection frame 17. A pipe cover 23 is provided on the outside of the connecting pipe 22. The pipe cover 23 is used to seal the connecting pipe 22 to prevent impurities from leaking and external impurities from entering. A sealing protrusion is fixedly connected to one side of the pipe cover 23. The sealing protrusion can enhance the sealing between the pipe cover 23 and the connecting pipe 22. Two locking bolts are threadedly connected to one side of the pipe cover 23. Two threaded holes are opened on one side of the connecting pipe 22. The locking bolts are threadedly connected to the inside of the threaded holes. The locking bolts can firmly fix the pipe cover 23 to the connecting pipe 22.

[0023] Working principle: When this lubricating oil filtration device is working, the lubricating oil enters the upper filter tank 2 from the inlet pipe 3 and then flows into the lower filter tank 1. In the lower filter tank 1, the lubricating oil will be filtered by the arc surface filter plate 8 and the filter ring 6, so that impurities are intercepted on the upper surface of the arc surface filter plate 8 and the filter ring 6. The filtered clean lubricating oil is discharged from the device through the drain pipe 4. As the filtration process continues, a large amount of impurities will gradually accumulate on the arc-shaped filter plate 8 and the filter ring 6. When it is necessary to discharge the slag, the hydraulic cylinder 9 is activated. The output end of the hydraulic cylinder 9 drives the connecting frame 12 to move upward. At the same time, the inner column 11 slides inside the outer shell 10. The connecting frame 12 connected to the output end of the hydraulic cylinder 9 also moves upward in sync. The two connecting frames 12 together drive the annular frame 13 and the multi-rod frame 14 to move upward. Since the positions of the pins 15 on the upper surface of the annular frame 13 and the filter holes inside the filter ring 6 are corresponding, and the positions of the pins 15 on the multi-rod frame 14 and the filter holes on the arc-shaped filter plate 8 are corresponding, the multiple pins 15 on the upper surface of the annular frame 13 and the multi-rod frame 14 respectively push into the internal filter holes of the filter ring 6 and the arc-shaped filter plate 8, pushing out the impurities accumulated inside. At the same time, the variable speed motor 24 is started. The output end of the variable speed motor 24 drives the rotating shaft 25 to rotate. The rotating shaft 25 drives the scraper 26 to rotate. The scraper 26 scrapes away the impurities on the upper surface of the arc surface filter plate 8 and the filter ring 6. The impurities will be guided down by the arc surface of the arc surface filter plate 8 and fall onto the filter ring 6. As the scraper 26 continues to rotate, it is easy to push the impurities on the filter ring 6 into the chip collection frame 17, thereby further enhancing the slag discharge effect. The iron block 18 on the lower surface of the chip collection frame 17 is attracted to the magnet frame 21, so that the chip collection frame 17 is stably fixed in the installation port 16. The operator can observe the collection of impurities in the chip collection frame 17 through the transparent shell 5. When a lot of impurities are collected, the locking bolt can be unscrewed, the pipe cover 23 can be opened, and the impurities in the chip collection frame 17 can be cleaned through the connecting pipe 22. Alternatively, the chip collection frame 17 can be pulled out from the installation port 16 by the pull handle 19 for cleaning. After cleaning, the chip collection frame 17 can be reinstalled in its original position, so that the iron block 18 is attracted to the magnet frame 21 again and can be used again.
