Description

Technical Field

[0001] This utility model relates to the field of oil and gas filter element technology, specifically to an oil and gas filter element with an impact-resistant outer layer protection. Background Technology

[0002] In the field of industrial lubricating oil and hydraulic oil filtration, traditional filter elements typically use a single-precision filtration layer (such as glass fiber, metal mesh, or polymer materials) to trap contaminants. However, during system startup, shutdown, or drastic changes in operating conditions, the oil flow and pressure fluctuate violently, generating powerful instantaneous impact forces. This hydraulic shock directly affects the filter element, causing structural damage, pleat collapse, or end cap adhesion failure of its core filtration medium, thus completely losing its filtration efficiency.

[0003] Traditional filter cartridges typically consist of a filter media layer, a support layer, and a central skeleton, arranged from the outside in. The central skeleton serves as the pressure-bearing structure of the filter cartridge. Traditionally, these are made by rolling and welding ordinary metal wire mesh or perforated plates. This method cannot adequately enhance the overall strength and impact resistance of the filter cartridge's support structure. Furthermore, due to the lack of a cleaning structure in the filter media's inner filtration chamber, the filter pores are prone to clogging due to prolonged contact with oil, thus affecting the filtration effect.

[0004] Therefore, it is necessary to invent an oil and gas filter element with an impact-resistant outer protective layer to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an oil and gas filter element with an impact-resistant outer protective layer. The welded outer mesh protects the metal coarse filter screen, the middle layer of coarse fiber filter media, and the inner layer of polymer barrier membrane core, preventing collisions and drops during installation, replacement, or transportation. Combined with evenly spaced vertical reinforcing ribs on the inner side, it provides rigidity to the entire filter element structure, preventing the internal filter media from being crushed or deformed by high pressure differentials or impact forces. Through the arrangement and cooperation of gear one, a servo motor, a drive rod, gear two, and a turntable, a cleaning rod can be driven to clean along the inner and outer sides of the metal coarse filter screen, reducing filter pore blockage and its impact on subsequent filtration efficiency, thus improving the filter element's service life. This addresses the problems in existing technologies where the overall strength and impact resistance of the filter element support structure cannot be adequately enhanced, and where the lack of a cleaning structure in the inner filter cavity of the filter media leads to pore blockage due to prolonged contact with oil, affecting filtration efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an oil and gas filter element with impact-resistant outer layer protection, comprising a lower end cover, on which a welded outer mesh is detachably fitted; vertical reinforcing ribs are fixedly connected to the outer edge of the lower end cover; the number of vertical reinforcing ribs is set to multiple; the multiple vertical reinforcing ribs are arranged in a ring array about the center point of the lower end cover; the tops of the multiple vertical reinforcing ribs are all fixedly connected to an upper end cover; a turntable is provided on the top of the lower end cover; a metal coarse filter screen, a middle layer of cohesive fiber filter material, and an inner layer of polymer barrier membrane core are arranged inside the welded outer mesh between the turntable and the upper end cover; the tops of the metal coarse filter screen, the middle layer of cohesive fiber filter material, and the inner layer of polymer barrier membrane core are all fixedly connected to the upper end cover; and a cleaning rod located inside and outside the metal coarse filter screen is fixed at the end of the turntable.

[0007] Preferably, a rotating rod is rotatably connected inside the lower end cover, the end of the rotating rod is fixedly connected to the turntable, and a gear is fixedly fitted on the rotating rod.

[0009] Preferably, the upper end cap has a through hole in the middle, and the through hole is located above the inner polymer barrier membrane core.

[0010] Preferably, the lower end cover has symmetrically formed movable cavities, and a limiting block is slidably arranged inside the movable cavity. A spring is fixedly connected between the side of the limiting block and the movable cavity. An insert block is fixed on the side of the limiting block away from the spring. Slots matching the insert blocks are symmetrically formed on the inner side of the welding mesh. A limiting groove is formed at the bottom of the movable cavity, and an operating block that cooperates with the limiting groove is fixed at the bottom of the limiting block.

[0011] Preferably, a shock-absorbing washer is fixedly fastened between the outer side of the lower end cover and the welded outer mesh, and a shock-absorbing washer is fixedly fastened between the outer side of the upper end cover and the welded outer mesh.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows: 1.

[0016] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0017] This utility model provides, for example Figure 1-5The oil and gas filter element with an impact-resistant outer protective layer shown includes a lower end cover 1, on which a welded outer mesh 2 is detachably fitted. Vertical reinforcing ribs 24 are fixedly connected to the outer edge of the lower end cover 1. The number of vertical reinforcing ribs 24 is set to multiple, and the multiple vertical reinforcing ribs 24 are arranged in a ring array about the center point of the lower end cover 1. The vertical reinforcing ribs 24 are close to the inner side of the welded outer mesh 2, providing auxiliary support for the welded outer mesh 2 and being able to withstand greater impact force and pressure difference. The intersections in the welded outer mesh 2 are welded together by resistance welding to form a very strong and rigid metal mesh structure, further improving the effect of withstanding greater impact force and pressure difference. The tops of multiple vertical reinforcing ribs 24 are fixedly connected to the upper end cover 13. A turntable 11 is provided on the top of the lower end cover 1. The welded outer mesh 2 contains a metal coarse filter screen 3, a middle layer of coagulating fiber filter material 4, and an inner layer of polymer barrier membrane core 5 located between the turntable 11 and the upper end cover 13. The metal coarse filter screen 3 can be a coarse filtration layer made of glass fiber, metal mesh, or coarse polyester fiber. Its function is to intercept larger solid particles and oil droplets, achieving preliminary coagulation and separation. The middle layer of coagulating fiber filter material 4 can be composed of high-efficiency coagulating fibers. The middle layer has denser fibers, which can further aggregate fine oil mist droplets, allowing small droplets to aggregate into large droplets. The inner polymer barrier membrane core 5 can be a high-precision barrier layer made of polymer membrane, stainless steel mesh or sintered material. Its function is to perform sterilization-level filtration, effectively intercept the smallest particles, and achieve absolute liquid removal, ensuring that no liquid oil or water can pass through, allowing only pure gas to pass through. The pure gas flows out from the inner channel of the inner polymer barrier membrane core 5 and is discharged smoothly through the through hole 14. The tops of the metal coarse filter screen 3, the middle layer coagulated fiber filter material 4, and the inner layer polymer barrier membrane core 5 are all fixedly connected to the upper end cover 13. The end of the turntable 11 is fixed with a cleaning rod 12 located inside and outside the metal coarse filter screen 3. The cleaning rod 12 is close to the inside and outside of the metal coarse filter screen 3 and can clean the impurities accumulated in the surface filter holes during operation.

[0018] The lower end cover 1 is rotatably connected to a rotating rod 6. The end of the rotating rod 6 is fixedly connected to the turntable 11. A gear 7 is fixedly mounted on the rotating rod 6.

[0019] A servo motor 8 is installed inside the lower end cover 1. The output shaft of the servo motor 8 is fixedly connected to a drive rod 9 via a coupling. A gear 2 10 is fixedly mounted on the drive rod 9. The gear 2 10 cooperates with the gear 1 7. When the gear 1 7 and the gear 2 10 are meshed, the turntable 11 can synchronously drive the cleaning rod 12 to rotate for self-cleaning operation.

[0020] A through hole 14 is provided in the middle of the upper end cover 13, and the through hole 14 is located above the inner polymer barrier membrane core 5.

[0021] The lower end cover 1 has symmetrically arranged movable cavities 15. A limit block 16 is slidably arranged inside the movable cavity 15. A spring 17 is fixedly connected between the side of the limit block 16 and the movable cavity 15. An insert block 18 is fixed on the side of the limit block 16 away from the spring 17. The inner side of the welding mesh 2 has symmetrically arranged slots 19 that match the insert block 18. A limit groove 20 is opened at the bottom of the movable cavity 15. An operating block 21 that cooperates with the limit groove 20 is fixed at the bottom of the limit block 16. By moving the operating block 21 in the limit groove 20, the limit block 16 can be driven to slide in the movable cavity 15, and the insertion state of the insert block 18 and the slot 19 can be adjusted, which makes it easy to remove the welding mesh 2 separately for cleaning.

[0022] A shock-absorbing washer 22 is fixedly fastened between the outer side of the lower end cover 1 and the welded outer mesh 2, and a shock-absorbing washer 23 is fixedly fastened between the outer side of the upper end cover 13 and the welded outer mesh 2. The shock-absorbing washer 22 and the shock-absorbing washer 23 work together to prevent the impact force on the welded outer mesh 2 from being transmitted to the internal filter material, thereby improving its service life.

[0023] The working principle of this practical application is as follows: When the filter media in the device needs to be cleaned, the servo motor 8 is driven to work. The servo motor 8 drives the gear 10 and the gear 7 meshing with it to rotate synchronously, so that the turntable 11 drives the cleaning rod 12 to rotate. The cleaning rod 12 rotates in close contact with the inner and outer sides of the metal coarse filter screen 3, which can clean the impurities accumulated in the filter holes and avoid clogging that affects the filtration effect of oil and gas. In addition, by moving the operating block 21 in the limiting groove 20, the limiting block 16 is driven to slide in the moving cavity 15, so that the insert 18 is separated from the slot 19, and the welded outer mesh 2 can be removed separately for easy cleaning.

[0024] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
