Description

Technical Field

[0001] This utility model relates to the field of oil filtration technology, specifically to an oil filtration structure for an air compressor. Background Technology

[0002] An air compressor is a device used to compress gas. Air compressors are similar in construction to water pumps. Most air compressors are reciprocating piston, rotary vane, or rotary screw types. An oil filter is an essential component of oil-cooled air compressors. During operation, because the compressed air is under high temperature and pressure, some of the lubricating oil inside the compressor inevitably vaporizes into oil vapor and small oil droplets, which enter the exhaust pipe along with the compressed air. If these oil droplets and oil vapor enter the cooler, it will reduce the cooler's cooling efficiency. Therefore, an oil filter must be installed between the compressor and the cooler to separate the lubricating oil from the refrigerant vapor. Because the oil contains many impurities, the oil-gas separation process is under a heavy load, necessitating pre-filtration.

[0003] Chinese Patent CN217746002U discloses an air compressor oil filter structure, relating to the field of oil filtration structures. It solves the problem of inconvenient and rapid replacement of the internal filter element in existing air compressor oil filter structures during installation. The proposed solution includes a housing, a base plate assembly, a bypass valve, an oil inlet check valve, a filter cartridge, a threaded collar, a threaded ring platform, bolt holes, bolts, a filter element, and a sealing ring. Both the housing and the base plate assembly have annular grooves. Limiting ring platforms are fixedly fitted at both the upper and lower ends of the outer side of the filter cartridge. Mounting seats are fixedly connected in an array to the inner walls of the housing and the base plate assembly. Each mounting seat has a fixedly connected sliding rod. The sliding rods on the same upper and lower sides are slidably fitted with a circular ring. Sealing rubber rings are fixedly fitted between the circular rings on the upper and lower sides and the housing and base plate assembly, respectively. This device features convenient disassembly and replacement, as well as good sealing performance.

[0004] However, the above technical solution has the following shortcomings: using bolts to connect the base plate assembly and the outer shell makes the installation and disassembly steps cumbersome and inconvenient for filter element replacement. On the other hand, the vibration of the air compressor during operation can easily cause the bolts to loosen, affecting the reliability of the filter element installation. Utility Model Content

Multiple adjustment components 32 are provided and correspond one-to-one with the snap-fit ​​mechanism 4. The adjustment component 32 is used to adjust the position of the snap-fit ​​mechanism 4. One end of the adjustment component 32 is connected to the adjustment ring 31 and the other end of the adjustment component 32 is connected to the snap-fit ​​mechanism 4.

[0037] Example 2

[0038] like Figure 1-5As shown, the present invention discloses an air compressor oil filter structure. Compared with Embodiment 1, this embodiment also specifically discloses the structure of the snap-fit ​​mechanism 4. Each snap-fit ​​mechanism 4 includes a mounting box 41, a movable plate 42, a snap-fit ​​block 43, and a reset assembly 44. The mounting box 41 is fixedly connected to the mounting cover 5. The movable plate 42 is slidably disposed inside the mounting box 41. One end of the snap-fit ​​block 43 is fixedly connected to the movable plate 42, and the other end of the snap-fit ​​block 43 penetrates through the mounting box 41 and extends to the outside of the mounting box 41. The inner wall of the connecting cylinder 2 is provided with a connection to the snap-fit ​​block 43. A three-phase compatible snap-fit ​​slot 45 is provided. A reset assembly 44 is disposed inside the mounting box 41. One end of the reset assembly 44 is connected to the movable plate 42. The reset assembly 44 includes a reset spring 441 and a linkage rod 442. Both the reset spring 441 and the linkage rod 442 are disposed inside the mounting box 41. One end of the reset spring 441 is connected to the movable plate 42, and the other end of the reset spring 441 is fixedly connected to the mounting box 41. One end of the linkage rod 442 is connected to the movable plate 42, and the other end of the linkage rod 442 passes through the mounting box 41 and extends to the outside of the mounting box 41.

[0039] Example 3

[0040] like Figure 6 As shown, this utility model proposes an air compressor oil filter structure. Compared with Embodiment 2, this embodiment also specifically discloses the structure of the adjusting component 32. Each adjusting component 32 includes an adjusting block 321, a limiting block 322, and a returning component 323. The adjusting block 321 is located on the inner ring of the adjusting ring 31 and is fixedly connected to the adjusting ring 31. The limiting block 322 is located on the outer ring of the adjusting ring 31 and is fixedly connected to the adjusting ring 31. The linkage rod 442 has an adjusting hole 324 through one end located outside the mounting box 41. The adjusting ring 31 passes through... The adjustment hole 324 passes through the linkage rod 442 and is slidably connected to the linkage rod 442. The adjustment block 321 and the limit block 322 are respectively set on both sides of the adjustment hole 324. The return assembly 323 includes a fixed plate 3231, a pre-tightening spring 3232 and a connecting plate 3233. The fixed plate 3231 is fixedly connected to the mounting cover 5, the connecting plate 3233 is fixedly connected to the outer ring of the adjustment ring 31, one end of the pre-tightening spring 3232 is fixedly connected to the fixed plate 3231, and the other end of the pre-tightening spring 3232 is fixedly connected to the connecting plate 3233.

[0041] When the filter cartridge 6 needs to be replaced, rotating the adjusting ring 31 causes the adjusting block 321 and the limiting block 322 to move together. The limiting block 322 slides out of the adjusting hole 324 of the linkage rod 442, while the adjusting block 321 slides into the adjusting hole 324 of the linkage rod 442. When the adjusting block 321 slides into the adjusting hole 324, the locking block 43 slides out of the locking groove 45 through the linkage rod 442 and the movable plate 42. The mounting cover 5 loses its limiting position with the connecting cylinder 2. The mounting cover 5 is then removed from the connecting groove 7. After that, the filter cartridge 6 is removed from the mounting cylinder 1, and the new filter cartridge 6 is placed on top. The new mounting tube 1 is placed in the mounting sleeve 2, and then the mounting cover 5 is placed in the connecting groove 7. Under the action of the return spring 441, the snap-fit ​​block 43 is inserted into the snap-fit ​​groove 45 to complete the installation between the mounting cover 5 and the connecting sleeve 2. At the same time, the pre-tightening spring 3232 pushes the adjusting ring 31 to rotate through the connecting plate 3233. The rotation of the adjusting ring 31 drives the limiting block 322 to be inserted into the adjusting hole 324 of the linkage rod 442 to limit and fix the linkage rod 442. This can effectively prevent the snap-fit ​​block 43 from accidentally dislodging from the snap-fit ​​groove 45 and ensure the reliability of the connection between the mounting cover 5 and the connecting sleeve 2.

[0042] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
