[0002] Traditional filters suffer from two major technical challenges under high-pressure fluid conditions: firstly, abnormal vibration and noise caused by filter element clogging; and secondly, the need for shutdown and disassembly for cleaning during maintenance. While some existing filters utilize water backwashing, this structure is overly complex and wasteful of water resources. To address these shortcomings, we propose an aluminum filter vibration-damping and noise-reducing structure. Utility Model Content

[0027] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of an aluminum filter shock absorption and noise reduction structure of this utility model.

[0028] like Figure 1-7As shown, this utility model discloses an aluminum filter vibration reduction and noise reduction structure, including an aluminum filter cartridge 10 and a cartridge cover 11. An inlet pipe 12 and a drain pipe 13 are fixedly installed on the upper surface of the cartridge cover 11. Positioning rings 20 are fixedly installed on the opposite surfaces of the filter cartridge 10 and the cartridge cover 11. A cylindrical stainless steel filter element 21 is provided inside the filter cartridge 10. Its upper and lower ends are press-fitted with the positioning rings 20 through an insert tube 23 with a rubber ring 22. The rubber ring 22 is made of EPDM material, and its outer diameter is 0.5-1mm larger than the inner diameter of the positioning ring 20. The static compression is 15%-20%. When the insert tube 23 with the rubber ring 22 is inserted into the positioning ring 20, the outer diameter of the rubber ring 22 is forcibly compressed to the inner diameter of the positioning ring 20 to form a seal.

[0029] A nut 24 is fitted onto the surface of the cover 11. A threaded retaining ring 25 is fixedly installed on the outer surface of the filter cartridge 10. The cover 11 is screwed onto the retaining ring 25 by the nut 24. A stop ring 26 is fixedly installed on the surface of the cover 11. A sealing groove is formed between the cover 11 and the filter cartridge 10, and a sealing ring is installed in the sealing groove. When the cover 11 is pressed down vertically to align the stop ring 26 with the end face of the filter cartridge 10, the nut 24 is rotated so that its internal thread engages with the external thread of the retaining ring 25, thereby assembling the cover 11 and the filter cartridge 10. When the filter element 21 is integrated, the insertion tube 23 above the filter element 21 will be inserted into the positioning ring 20 on the cover 11. When water enters the inner cavity of the filter element 21 axially through the water inlet pipe 12, it is filtered by the stainless steel filter element 21 and discharged through the drain pipe 13. Impurities are trapped on the inner surface of the filter element 21. The EPDM rubber ring 22 between the insertion tube 23 and the positioning ring 20 absorbs axial vibration through 15%-20% compression deformation. When maintenance is required, the nut 24 is rotated counterclockwise until it is disengaged from the thread of the limit ring 25, which can separate the cover 11 from the filter element 10.

[0030] The filter cartridge 10 is provided with a magnetic drive cleaning mechanism, which includes a guide ring 30 sleeved on the outside of the filter cartridge 10 and a first annular magnet 31 fixedly installed on the inner ring surface of the guide ring 30. A second annular magnet 33 with a brush 32 is sleeved on the outer periphery of the filter element 21. A guide mechanism is provided for guiding the guide ring 30. The guide mechanism includes a guide plate 40 fixed on the surface of the filter cartridge 10, three guide rods 41 fixedly installed on the upper surface of the guide plate 40 in a circumferential array, and three guide holes corresponding to the guide ring 30 in a circumferential array. The upper end of the guide rod 41 is connected to a limiting ring 25. The sliding cooperation between the guide rod 41 and the guide hole restricts the movement trajectory of the cleaning mechanism. The limiting ring 25 prevents excessive displacement.

[0031] The first annular magnet 31 and the second annular magnet 33 are spaced 5-8 mm apart, with their magnetic poles N and S arranged opposite each other. The brush 32 is made of nylon 612 material with a bristle diameter of 0.1 mm. The working surface of the brush 32 is in contact with the surface of the filter element 21. When the pressure difference of the filter element 21 exceeds 0.15 MPa, the operator manually slides the guide ring 30 axially. The first annular magnet 31 drives the second annular magnet 33 through the attraction of the N and S poles within a 5-8 mm gap, which drives the nylon brush 32 to scrape the surface of the filter element 21 for the entire stroke. The nylon 612 material with a bristle diameter of 0.1 mm can remove large particles of impurities without damaging the filter element 21.

[0032] The lower end of the filter cartridge 10 is connected to the drain pipe 14, which is coaxial with the water inlet pipe 12. A drain valve 15 is provided on the surface. The stripped impurities settle along the coaxially designed drain pipe 14 under the action of gravity. After the drain valve 15 is opened, a vortex flushing effect is formed, which completely discharges the accumulated material.

[0033] Working principle:

[0034] Insert the tube 23 with the EPDM rubber ring 22 vertically into the positioning ring 20 of the filter cartridge 10 and the cartridge cover 11 to ensure an interference seal to form a shock-absorbing structure.

[0035] Fixing the cover 11: After aligning the stop ring 26 with the end face of the filter cylinder 10, rotate the nut 24 clockwise to engage the threaded limit ring 25, thus completing the axial locking.

[0036] Operation and Cleaning

[0037] Filtration Start-up: Water enters the inner cavity of filter element 21 through water inlet pipe 12, and is discharged through drain pipe 13 after filtration. Rubber ring 22 absorbs vibration noise.

[0038] Magnetic drive cleaning: When the pressure difference is >0.15MPa, manually slide the guide ring 30 and drive the nylon brush 32 to scrape the surface of the filter element 21 through the NS magnetic pole.

[0039] Sewage discharge operation: Open the bottom drain valve 15 and use the vortex effect of the coaxial drain pipe 14 to remove settled impurities.

[0040] Maintenance and disassembly: Rotate the nut 24 counterclockwise to disengage the thread of the limit ring 25, lift the cylinder cover 11 vertically, and remove the filter element 21 for replacement or deep cleaning.

Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model.
