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 a deformable frame. Background Technology

[0002] Air filter elements are core filtration components in hydraulic, lubrication, and compressed air systems. Their technological development is closely related to modern industry's requirements for equipment reliability, efficiency, and lifespan.

[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, which cannot adequately enhance the overall strength 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 a deformable skeleton to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an oil and gas filter element with a deformable skeleton. Through the design of vertical reinforcing ribs and through holes, the vertical reinforcing ribs, in conjunction with the protective steel mesh, protect the inner and outer sides of filter media one and two while providing support for the inner sides of filter media one and two, thus improving structural strength. Furthermore, the vertical reinforcing ribs, the upper end cover, the middle partition steel plate, and the lower end cover form a robust whole, further increasing structural strength. The servo motor, bidirectional lead screw, moving block, transmission rod, and connecting rod, used in conjunction, can drive two cleaning blocks to move along the inner surface of the protective steel mesh and the outer surface of filter media one, cleaning oil and impurities clogging the filter holes of filter media one. This prevents clogging from affecting subsequent filtration performance, thus solving the problem in existing technologies where the overall strength 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 clogging of the filter holes due to prolonged contact with oil, affecting filtration efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a deformable oil and gas filter element, comprising a middle steel plate, an upper end cover, and a lower end cover. The middle steel plate is disposed between the upper end cover and the lower end cover. Filter media is fixed between the middle steel plate and both the upper and lower end covers. A protective steel mesh located outside the filter media is fixed between the middle steel plate and both the upper and lower end covers. A filter passage cavity is provided between the filter media and the protective steel mesh. A servo motor is installed on the side of the lower end cover. The output shaft of the servo motor is fixedly connected to a bidirectional lead screw via a coupling. The bidirectional lead screw is rotatably connected to the lower end cover. Moving blocks are symmetrically mounted on the bidirectional lead screw. The moving blocks are threadedly connected to the bidirectional lead screw. A transmission rod is hinged to the top of the moving blocks. A connecting rod penetrating the lower end cover is hinged to the end of the transmission rod away from the moving blocks. The connecting rod is slidably connected to the lower end cover.

[0007] Preferably, the upper end of the connecting rod is fixed with a cleaning block located inside the filter passage cavity, and the cleaning block matches the filter passage cavity.

[0008] Preferably, filter material two is fixed between the middle partition steel plate and the upper end cover and the lower end cover, and is located inside the filter material one.

[0009] Preferably, the bottom wall inside the lower end cover is symmetrically provided with guide grooves that match the moving block.

[0010] Preferably, both filter media one and filter media two have vertical reinforcing ribs fixed at equal intervals on their inner sides.

[0011] Preferably, the middle partition steel plate has a through hole in the middle, and the through hole is connected to the filter cavity.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows: 1. By setting vertical reinforcing ribs and through holes, the vertical reinforcing ribs, in conjunction with the protective steel mesh, protect the inner and outer sides of filter media one and filter media two while providing support for the inner sides of filter media one and filter media two, thereby improving structural strength. The vertical reinforcing ribs, together with the upper end cover, the middle partition steel plate, and the lower end cover, form a solid whole, further increasing structural strength. The servo motor, bidirectional lead screw, moving block, transmission rod, and connecting rod, when used in conjunction, can drive the two cleaning blocks to move along the inner surface of the protective steel mesh and the outer surface of filter media one, cleaning the oil and debris clogging the filter holes of filter media one and preventing clogging from affecting the subsequent filtration effect.

[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 1-5 The oil and gas filter element shown is a skeleton anti-deformation filter element, including a middle steel plate 1, an upper end cover 2 and a lower end cover 3. The middle steel plate 1 is located between the upper end cover 2 and the lower end cover 3. Filter media 4 is fixed between the middle steel plate 1 and the upper end cover 2 and the lower end cover 3. The filter media 4 plays a primary filtration role for the passing oil and gas. The filter holes on the filter media 4 are arranged in a staggered rather than straight arrangement, just like the bricklaying method, which can avoid the generation of continuous weak lines of strength, disperse stress, and improve the overall strength. A protective steel mesh 6 located outside the filter material 4 is fixed between the middle partition steel plate 1 and the upper end cover 2 and the lower end cover 3. A filter passage cavity 7 is provided between the filter material 4 and the protective steel mesh 6. A servo motor 8 is installed on the side of the lower end cover 3. The output shaft of the servo motor 8 is fixedly connected to a double-acting screw 9 through a coupling. The double-acting screw 9 is rotatably connected to the lower end cover 3. Moving blocks 10 are symmetrically mounted on the double-acting screw 9. The moving blocks 10 are threadedly connected to the double-acting screw 9. A transmission rod 11 is hinged to the top of the moving blocks 10. The end of the transmission rod 11 away from the moving block 10 is hinged to a connecting rod 12 that passes through the lower end cover 3. The connecting rod 12 is slidably connected to the lower end cover 3. While the moving block 10 moves along the bidirectional screw 9, it can push the connecting rod 12 to move through the transmission rod 11 until the transmission rod 11 and the connecting rod 12 are in a vertical state. This is used to control the cleaning block 13 to move up and down along the filter passage 7. The inner and outer sides of the cleaning block 13 are attached to the inner side of the protective steel mesh 6 and the outer side of the filter material 4 to achieve the cleaning effect of accumulated oil and dirt.

[0018] The upper end of the connecting rod 12 is fixed with a cleaning block 13 located in the filter passage 7, and the cleaning block 13 matches the filter passage 7.

[0019] A second filter material 5 is fixed between the middle partition steel plate 1 and the upper end cover 2 and the lower end cover 3, located inside the first filter material 4. The second filter material 5 can perform secondary filtration on the passing oil and gas, thereby improving the filtration effect.

[0020] The bottom wall inside the lower end cover 3 is symmetrically provided with guide grooves 14 that match the moving block 10. The moving block 10 can slide along the guide grooves 14 to limit the moving block 10 to move back and forth in a straight line along the bidirectional lead screw 9.

[0021] Vertical reinforcing ribs 15 are fixed at equal intervals on the inner side of both filter media 1 4 and filter media 2 5. The vertical reinforcing ribs 15 provide auxiliary support for the inner side of filter media 1 4 and filter media 2 5, effectively strengthening the vertical rigidity and bending resistance of filter media 1 4 and filter media 2 5, and preventing them from being crushed.

[0022] A through hole 16 is provided in the middle of the partition steel plate 1, and the through hole 16 is connected to the filter cavity 7.

[0023] The working principle of this practical application is as follows: Oil and gas pass through the protective steel mesh 6 into the filter passage 7 and then through the filter material 4 and filter material 5 in sequence. They then pass through the through hole 16 and through the filter material 5 and filter material 4 on the middle partition steel plate 1. After filtration, the filter is discharged, completing the filtration process. If it is necessary to clean the filter structure, the servo motor 8 is started. The servo motor 8 drives the bidirectional lead screw 9 to rotate, so that the moving block 10 moves along the bidirectional lead screw 9. The transmission rod 11 pushes the connecting rod 12 through the lower end cover 3. As the angle of the transmission rod 11 changes, the connecting rod 12 drives the cleaning block 13 to extend into the filter passage 7. The cleaning block 13 is used to clean impurities by adhering to the inner and outer surfaces of the protective steel mesh 6 and filter material 4, so as to avoid clogging of the filter holes.

[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.
