Description

Technical Field

[0001] This utility model relates to the field of filter technology, and in particular to a lubricating oil filter for removing impurities from lubricating oil. Background Technology

[0002] Lubricating oil plays a crucial role in the operation of various mechanical equipment. It not only reduces friction between parts and lowers wear, but also provides cooling, sealing, and rust prevention. However, with continuous operation, various impurities inevitably mix into the lubricating oil. The presence of these impurities severely affects the performance of the lubricating oil and the normal operation of the machinery. To ensure the cleanliness of the lubricating oil, various types of lubricating oil filters are widely used in existing technologies. These filters typically possess the following technical characteristics:

[0003] 1. Filter materials and structure: Filter media with different materials and structures are selected, such as activated carbon filter media, cotton fiber, polyester fiber and other materials, to achieve high-precision filtration by utilizing their adsorption properties for impurities.

[0004] 2. Self-cleaning function: Some advanced filters are equipped with self-cleaning devices, such as backwashing mechanisms. After the filter has been working for a period of time, the intercepted impurities are discharged by backwashing the filter media, restoring the filter's filtration performance and reducing manual maintenance costs and downtime.

[0005] Currently, manufacturers employ various equipment and methods to achieve effective cleaning of the filter media inside the filters. Some manufacturers install valves at the top of the filters to inject high-pressure cleaning fluid for flushing and cleaning.

[0006] However, the above method has a prominent hardware structure problem: although some filters have self-cleaning functions, their fixed rinsing direction often results in unsatisfactory cleaning effects. Since there are often more than one filter element, the fixed rinsing direction means that the filter element can only be rinsed from a specific angle. Some surface areas of the filter element are difficult to be effectively rinsed. For example, only a small amount of cleaning liquid may reach the side of the filter element that is not facing the rinsing direction, resulting in impurities in that area not being fully removed. Over time, this accumulation will cause the filtration performance of this part of the filter element to decline more quickly. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a lubricating oil filter for removing impurities from lubricating oil. It solves the problem that although some filters have self-cleaning functions, their fixed rinsing direction often results in unsatisfactory cleaning effects. Since there are often more than one filter element, a fixed rinsing direction means that the filter element can only be rinsed from a specific angle. Some areas of the filter element surface are difficult to be effectively rinsed, such as the side of the filter element facing away from the rinsing direction, where only a small amount of cleaning fluid may reach. As a result, impurities in this area cannot be fully removed, and long-term accumulation will cause the filtration performance of this part of the filter element to decline more quickly.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A lubricating oil filter for removing impurities from lubricating oil includes a filter top cover. An inlet valve is provided at the upper end of the filter top cover. An adjustment mechanism for multi-angle spraying is provided on the inner surface of the filter top cover. The adjustment mechanism includes a cylindrical mounting platform, a first adjustment tube, and a second adjustment tube. The cylindrical mounting platform is fixedly connected to the inner surface of the filter top cover. The first adjustment tube is rotatably connected inside the cylindrical mounting platform, and the second adjustment tube is rotatably connected inside the first adjustment tube. A drive mechanism for driving adjustment is provided on the outer surfaces of the cylindrical mounting platform and the first adjustment tube. The drive mechanism includes two first drive motors, which are respectively fixedly connected to the cylindrical mounting platform and the outer surfaces of the first adjustment tubes. Spur gears are fitted onto the outer surfaces of the two first drive motors, the first adjustment tube, and the second adjustment tube.

[0010] Preferably, the two sets of spur gears mesh with each other, and the filter body is provided at the lower end of the filter top cover.

[0011] Preferably, a filter element mounting bracket is rotatably connected inside the filter body, and a set of filter element bodies are arranged inside the filter element mounting bracket.

[0012] Preferably, the filter element mounting bracket has a set of through slots inside.

[0013] Preferably, a second drive motor is fixedly connected to the lower end of the filter body.

[0014] Preferably, a pressure gauge is threadedly connected to the inside of the filter top cover, and an oil inlet flange pipe is fixedly connected to the outer surface of the filter body.

[0015] Preferably, an oil drain flange is fixedly connected to the end of the outer surface of the filter body away from the oil inlet flange, and a set of external threaded rods is rotatably connected inside the filter body.

[0016] Preferably, all of the external threaded rods in a group are threaded with a locking nut on their outer surface.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The inlet valve on the top cover of the filter injects high-pressure cleaning water to clean the inside of the filter. Its internal adjustment mechanism consists of a cylindrical mounting platform fixed to the inner surface of the top cover, a first adjustment tube rotatably connected to the cylindrical mounting platform, and a second adjustment tube rotatably connected to the first adjustment tube. The drive mechanism includes two first drive motors with external batteries, which are fixed to the cylindrical mounting platform and the first adjustment tube respectively. The spur gear on the output shaft of the motor meshes with the spur gear on the outside of the adjustment tube. When the motor is started, it can drive the first adjustment tube to rotate circumferentially and the second adjustment tube to change the water outlet angle, allowing the high-pressure water to cover a larger rinsing area, effectively removing impurities attached to the filter element, cleaning a larger area in a short time, reducing cleaning time, improving equipment turnover efficiency, and enabling the filter to be quickly put back into use.

[0019] Second, when the cleaning fluid is sprayed downward through the second regulating pipe, the output shaft of the second drive motor at the lower end of the filter body drives the filter element mounting bracket to rotate, which in turn drives the filter element body to rotate. The rotation of the filter element body allows the cleaning fluid to come into more comprehensive contact with the filter element surface, improving cleanliness. Under the combined action of the friction generated by the rotation and the impact force of the cleaning fluid, it is easier to detach from the filter element surface, thus cleaning the filter element more thoroughly.

[0027] This application provides a lubricating oil filter for removing impurities from lubricating oil. It effectively solves the problem that while some filters have self-cleaning functions, their fixed flushing direction often results in unsatisfactory cleaning. Since there are often multiple filter elements, a fixed flushing direction means that the filter elements can only be flushed from a specific angle, making it difficult to effectively clean some surface areas of the filter elements. For example, only a small amount of cleaning fluid may reach the side of the filter element facing away from the flushing direction, resulting in insufficient removal of impurities in that area. Long-term accumulation will cause the filtration performance of this part of the filter element to decline more rapidly. The filter's internal components are cleaned by injecting high-pressure cleaning water through the inlet valve on the top cover. Its internal adjustment mechanism consists of a cylindrical mounting platform fixed to the inner surface of the top cover, a first adjustment tube rotatably connected to the cylindrical mounting platform, and a second adjustment tube rotatably connected to the first adjustment tube. The drive mechanism includes two first drive motors with external batteries, which are fixed to the cylindrical mounting platform and the first adjustment tube respectively. The spur gear on the output shaft of the motor meshes with the spur gear on the outside of the adjustment tube. When the motor is started, it can drive the first adjustment tube to rotate circumferentially and the second adjustment tube to change the water outlet angle, allowing high-pressure water to cover a larger rinsing area, effectively removing impurities attached to the filter element, cleaning a larger area in a short time, reducing cleaning time, improving equipment turnover efficiency, and enabling the filter to be quickly put back into use. Example

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the technical solution in this application effectively solves the problem that although some filters have self-cleaning functions, their fixed rinsing direction often results in unsatisfactory cleaning effects. Since there are often more than one filter element, a fixed rinsing direction means that the filter element can only be rinsed from a specific angle, making it difficult to effectively clean some surface areas of the filter element. For example, on the side of the filter element facing away from the rinsing direction, only a small amount of cleaning liquid may reach it, resulting in impurities in that area not being fully removed. Long-term accumulation will cause the filtration performance of this part of the filter element to decline more quickly. The overall idea is as follows: a lubricating oil filter for removing impurities from lubricating oil. The system includes a filter top cover 11, with an inlet valve 12 at the upper end. The inner surface of the filter top cover 11 is provided with an adjustment mechanism for multi-angle spraying. The adjustment mechanism includes a cylindrical mounting platform 13, a first adjustment pipe 14, and a second adjustment pipe 15. The cylindrical mounting platform 13 is fixedly connected to the inner surface of the filter top cover 11. The first adjustment pipe 14 is rotatably connected inside the cylindrical mounting platform 13, and the second adjustment pipe 15 is rotatably connected inside the first adjustment pipe 14. The outer surfaces of the cylindrical mounting platform 13 and the first adjustment pipe 14 are provided with a drive mechanism for adjustment. The drive mechanism includes two first drive motors 16 and two first drive... Motors 16 are fixedly connected to the cylindrical mounting platform 13 and the outer surface of the first adjusting tube 14, respectively. Spur gears 17 are fitted onto the outer surfaces of the two first drive motors 16, the first adjusting tube 14, and the second adjusting tube 15. The two sets of spur gears 17 mesh with each other. The filter top cover 11 is used to cover the upper end of the filter. A liquid inlet valve 12 installed on the upper end of the filter top cover 11 injects high-pressure cleaning water to clean the inside of the filter. During the high-pressure water injection operation, the two first drive motors 16 can be started respectively. The two first drive motors 16 are respectively mounted on the cylindrical mounting platform 13 and the outer surface of the first adjusting tube 14 via mounting brackets. Both first drive motors 16 are battery-powered motors, and spur gears 17 are mounted on the output shafts of both first drive motors 16. The rotation of the output shafts of the two first drive motors 16 will drive the two sets of spur gears 17 to mesh respectively. The meshing of the two upper spur gears 17 will drive the first regulating tube 14 to rotate circumferentially, and the meshing of the two lower spur gears 17 will drive the second regulating tube 15 to rotate and change the water outlet angle. By adjusting the angle of the second regulating tube 15 and through the circumferential rotation of the first regulating tube 14, a larger rinsing area can be covered, which can not only rinse and clean the filter media, but also rinse the inner wall of the filter more effectively.

[0029] A filter body 18 is provided at the lower end of the filter top cover 11. A filter element mounting bracket 19 is rotatably connected inside the filter body 18. A set of filter element bodies 21 are provided inside the filter element mounting bracket 19. A set of through grooves 22 are opened inside the filter element mounting bracket 19, and a set of filter element bodies 21 are respectively placed inside the set of through grooves 22. A second drive motor 23 is fixedly connected to the lower end of the filter body 18. The filter element mounting bracket 19 is set on the outer surface of the second drive motor 23. A pressure gauge 24 is threadedly connected inside the filter top cover 11. The filter top cover 11 and the filter body 18 are combined to form a filter. Impurities in the lubricating oil are adsorbed and filtered through the multiple filter element bodies 21 provided inside the filter body 18. The filter element body 21 contains The filter media, filter element body 21, is screwed into the filter element mounting bracket 19 via an internal thread. The filter element mounting bracket 19 is rotatably connected to the filter body 18, and its rotatable connection part is fitted with a sealing ring. When the filter element body 21 is screwed into the through groove 22, the screwing position of the filter element body 21 is limited. The output shaft of the second drive motor 23 can drive the filter element mounting bracket 19 to rotate. When the second regulating pipe 15 sprays cleaning liquid downward, the filter element mounting bracket 19 drives the filter element body 21 to rotate, thereby improving the cleanliness. A pressure gauge 24 is installed on the filter top cover 11. The pressure gauge 24 is screwed into the filter top cover 11 via an external threaded pipe joint. The pressure gauge 24 can detect the air pressure inside the filter body 18.

[0030] An oil inlet flange pipe 25 is fixedly connected to the outer surface of the filter body 18. An oil outlet flange pipe 26 is fixedly connected to the end of the filter body 18 away from the oil inlet flange pipe 25. A set of external threaded rods 27 are rotatably connected inside the filter body 18. Each set of external threaded rods 27 is threaded with a locking nut 28 on its outer surface. The locking nuts 28 are all located on the outer surface of the filter top cover 11. Lubricating oil enters the filter body 18 through the oil inlet flange pipe 25 installed inside the filter body 18. After impurities are removed by the filter element body 21, the lubricating oil is discharged through the oil outlet flange pipe 26 for use. The external threaded rods 27 rotatably connected to the locking nuts 28 inside the filter body 18 are tightened to lock the liquid inlet valve 12, thereby ensuring the stability of the filter top cover 11 and the filter body 18.

[0031] To address the problems existing in the prior art, this utility model provides a lubricating oil filter for removing impurities from lubricating oil. The filter top cover 11 has an inlet valve 12 that injects high-pressure cleaning water to clean the inside of the filter. Its internal adjustment mechanism consists of a cylindrical mounting platform 13 fixed to the inner surface of the top cover, a first adjustment pipe 14 rotatably connected to the cylindrical mounting platform 13, and a second adjustment pipe 15 rotatably connected to the first adjustment pipe 14. The drive mechanism includes two externally mounted battery-powered first drive motors 16, respectively fixed to the cylindrical mounting platform 13 and the first adjustment pipe 14. A spur gear 17 on the motor output shaft meshes with an external spur gear 17 on the adjustment pipe. Starting the motors causes the first adjustment pipe 14 to rotate circumferentially and the second adjustment pipe 15 to change its water outlet angle, allowing high-pressure water to cover a larger rinsing area, effectively removing impurities attached to the filter element. This allows for cleaning a larger area in a short time, reducing cleaning time, improving equipment turnover efficiency, and enabling the filter to be quickly put back into use.

[0032] Filter top cover 11: As the top part of the filter, it is used to cover the upper part of the filter and combines with the filter body 18 to form a complete filtration space;

[0033] Inlet valve 12: Installed on the upper end of the filter top cover 11, its main function is to inject high-pressure cleaning water to provide water source for the internal cleaning of the filter. It is a key inlet component for realizing the internal cleaning function of the filter.

[0034] Cylindrical mounting platform 13: It is fixedly connected to the inner surface of the filter top cover 11 and is the basic support component of the adjustment mechanism; it provides space and support for the first adjustment tube 14 to rotate, and at the same time serves as the fixed position of a first drive motor 16 in the drive mechanism.

[0035] First adjustment tube 14: Rotatably connected inside the cylindrical mounting platform 13. On the one hand, it serves as an intermediate transmission component of the adjustment mechanism, transmitting the power of the first drive motor 16 on the cylindrical mounting platform 13 to itself through the spur gear 17 to achieve circumferential rotation. On the other hand, it provides space and support for the rotational connection of the second adjustment tube 15.

[0036] The second regulating pipe 15 is rotatably connected inside the first regulating pipe 14. Under the action of the driving mechanism, it rotates to change the water outlet angle. Combined with the circumferential rotation of the first regulating pipe 14, it allows high-pressure cleaning water to be sprayed from different angles, which can not only rinse and clean the filter media, but also specifically rinse the inner wall of the filter, greatly improving the comprehensiveness and effectiveness of cleaning.

[0037] First drive motor 16: There are two in total, which are fixedly connected to the outer surface of the cylindrical mounting platform 13 and the first adjusting pipe 14, respectively. Both are battery-powered motors that provide power support for multi-angle spraying.

[0038] Spur gear 17: Two sets of spur gears 17 are respectively sleeved on the outer surfaces of the two first drive motors 16, the first regulating tube 14, and the second regulating tube 15, and transmit power through mutual meshing;

[0039] Filter body 18: Together with the filter top cover 11, it forms the filter as a whole, and provides installation space for components such as filter element mounting bracket 19 and filter element body 21 inside;

[0040] Filter element mounting bracket 19: It is screwed into the filter element body 21 through the internal thread, which limits the screwing position of the filter element body 21 and ensures that the filter element is installed firmly and in an accurate position; it rotates under the drive of the second drive motor 23, which in turn drives the filter element body 21 to rotate, so that the cleaning fluid can come into more comprehensive contact with the filter element surface and improve the cleanliness. At the same time, a sealing ring is sleeved on the rotating connection part of it and the filter body 18 to ensure the sealing of the filtration system.

[0041] Filter body 21: It uses internal filter media to adsorb impurities in lubricating oil to achieve the function of filtering lubricating oil; during the cleaning process, it rotates with the filter mounting bracket 19, so that the cleaning fluid can come into more comprehensive contact with its own surface, improve cleanliness, and thus maintain good filtration performance.

[0042] Through groove 22: It is formed inside the filter element mounting bracket 19 and is used to fit the filter element body 21, limit the screwing position of the filter element body 21, and ensure the accuracy and stability of the installation of the filter element body 21.

[0043] The second drive motor 23 is fixedly connected to the lower end of the filter body 18. Its output shaft is connected to the filter element mounting bracket 19. The output shaft rotates to drive the filter element mounting bracket 19 to rotate, which in turn drives the filter element body 21 to rotate. This allows the cleaning fluid to come into more comprehensive contact with the filter element surface during the cleaning process, improving the cleaning effect. It is the power source for the filter element rotation cleaning function.

[0044] Pressure gauge 24: Helps operators understand the internal pressure of the filter, promptly detect possible blockages or other abnormalities, ensure the safe and stable operation of the filter, and provide pressure monitoring function for the normal operation of the filter;

[0045] Oil inlet flange pipe 25: It is fixedly connected to the outer surface of the filter body 18 and serves as the inlet channel for lubricating oil to enter the interior of the filter body 18, guiding the lubricating oil into the interior of the filter.

[0046] Oil drain flange pipe 26: It is fixedly connected to the end of the filter body 18 away from the oil inlet flange pipe 25. It is the discharge channel for clean lubricating oil after being filtered by the filter element body 21, and discharges the lubricating oil after removing impurities for subsequent use.

[0047] External thread rod 27: By rotating on its own, it cooperates with the tightening nut 28 to tighten the filter top cover 11, ensuring the stability of the installation of the filter top cover 11 and the filter body 18, and preventing the equipment from being affected by loose connection during filtration and cleaning.

[0048] Tightening nut 28: By tightening the tightening nut 28, it is pressed against the filter top cover 11. Together with the external threaded rod 27, it ensures a tight connection between the filter top cover 11 and the filter body 18, ensuring the stability and sealing of the overall filter structure and preventing leakage and loosening of parts during operation.

[0049] Working principle:

[0050] The first step involves connecting a set of externally threaded rods 27 rotating inside the filter body 18 to a tightening nut 28. The tightening nut 28 is located on the outer surface of the filter top cover 11. By tightening the tightening nut 28, it secures the filter top cover 11, ensuring the stability of the installation between the filter top cover 11 and the filter body 18. This prevents loose connections from affecting normal equipment operation during filtration and cleaning. A pressure gauge 24 is threaded inside the filter top cover 11. The pressure gauge 24 is screwed into the filter top cover 11 via an externally threaded pipe fitting. The pressure gauge 24 can monitor the air pressure inside the filter body 18 in real time, helping operators understand the internal pressure of the filter, promptly detect potential blockages or other abnormalities, and ensure the safe and stable operation of the filter. The lubricating oil first enters the filter body 18 through the oil inlet flange pipe 25 on the outer surface of the filter body 18. The lubricating oil inside the filter body 18 passes through the filter element body 21, which contains filter media that can adsorb impurities in the lubricating oil. Multiple filter element bodies 21 are screwed into the through groove 22 in the filter element mounting bracket 19 by internal threads. The through groove 22 limits the screwing position of the filter element body 21, ensuring that it is installed firmly and in an accurate position. When the lubricating oil flows through the filter element body 21, the impurities in it are adsorbed by the filter media inside the filter element body 21, thereby achieving filtration. The clean lubricating oil after the impurities are removed by the filter element body 21 is discharged through the oil drain flange pipe 26 at the other end of the outer surface of the filter body 18 for subsequent use.

[0051] The second step involves injecting high-pressure cleaning water into the inlet valve 12 mounted on the upper end of the filter top cover 11 to clean the inside of the filter. An adjustment mechanism on the inner surface of the filter top cover 11 enables multi-angle spraying. This mechanism consists of a cylindrical mounting platform 13, a first adjustment pipe 14, and a second adjustment pipe 15. The cylindrical mounting platform 13 is fixed to the inner surface of the filter top cover 11. The first adjustment pipe 14 is rotatably connected inside the cylindrical mounting platform 13, and the second adjustment pipe 15 is rotatably connected inside the first adjustment pipe 14. The drive mechanism includes two first drive motors 16, respectively fixed to the cylindrical mounting platform 13 and the outer surface of the first adjustment pipe 14. Both first drive motors 16 are battery-powered motors, with spur gears 17 mounted on their output shafts, meshing with the spur gears 17 sleeved on the outer surfaces of the first and second adjustment pipes 14 and 15. When the two first drive motors 16 are started... The two spur gears 17 at the upper end mesh to drive the first regulating pipe 14 to rotate circumferentially, and the two spur gears 17 at the lower end mesh to drive the second regulating pipe 15 to rotate to change the water outlet angle. Through the adjustment of the angle of the second regulating pipe 15 and the circumferential rotation of the first regulating pipe 14, the high-pressure cleaning water can cover a larger rinsing area. It can not only rinse and clean the filter media, but also specifically rinse the inner wall of the filter. When the cleaning liquid is sprayed downward from the second regulating pipe 15, the output shaft of the second drive motor 23 at the lower end of the filter body 18 drives the filter element mounting bracket 19 to rotate, which in turn drives the filter element body 21 to rotate. The rotation of the filter element body 21 can make the cleaning liquid contact the filter element surface more comprehensively, improving the cleanliness. The rotating connection between the filter element mounting bracket 19 and the filter body 18 is fitted with a sealing ring to prevent the lubricating oil from leaking during the filtration process and to ensure the sealing of the filtration system.

[0052] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
