Description

Technical Field

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

[0002] Traditional air compressor oil filters typically use an integral filter element structure. When the filter cartridge reaches the end of its service life, the entire filter element needs to be replaced, leading to a significant increase in maintenance costs. Existing filter element structures are also difficult to adapt to filter cartridges of different lengths, limiting the versatility of the filter cartridges. Utility Model Content

[0003] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide an oil separation filtration structure that, by setting two bases and installing a retaining block in the bases, facilitates the replacement of the filter cartridge.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides an oil separation filtration structure, comprising:

[0005] Two bases, each base having a groove, and multiple abutment blocks disposed within the groove;

[0006] Connector, the connector being used to connect two bases;

[0007] The filter cartridge has two ends located in the grooves of two bases respectively. The clamping block clamps the ends of the filter cartridge against the groove wall. The cavity between the filter cartridge and the two bases forms a filtration cavity.

[0008] One of the bases has an air inlet that communicates with the filter chamber.

[0009] Preferably, the groove is circular, a limiting platform is provided in the groove, and a plurality of the clamping blocks are circumferentially distributed in the groove. The clamping blocks have the degree of freedom to slide radially along the groove on the limiting platform.

[0010] Preferably, the clamping block includes an arc-shaped segment and a straight segment fixed on the arc-shaped segment. The arc-shaped segment is used to clamp the end of the filter cartridge. The limiting platform is provided with multiple sliding grooves, and the straight segment is slidably installed in the sliding grooves.

[0011] Preferably, the limiting platform has a through hole in the middle, and the end of the straight section away from the arc section extends into the through hole. A driving block is provided on the base. When the driving block moves in the through hole, it pushes the straight section to move in the slide groove.

[0012] Preferably, a plurality of guide rods are fixed on the circumferential outer wall of the limiting platform, and the plurality of guide rods correspond one-to-one with a plurality of straight sections. A baffle is fixed to the end of the guide rod away from the limiting platform. A connecting plate is sleeved on the guide rod between the baffle and the limiting platform. The connecting plate is fixedly connected to the straight section. A spring is sleeved on the guide rod between the baffle and the connecting plate.

[0013] Preferably, the base has a stepped hole, and a locking rod is slidably installed on the stepped hole. One end of the locking rod is connected to the drive block, and the other end extends to the outside of the base; the locking rod is coaxial with the base.

[0014] Preferably, a first sealing ring is fitted on the locking rod, and the first sealing ring is used to seal the gap between the locking rod and the stepped hole.

[0015] Preferably, the stepped hole is provided with a threaded section, and the locking rod is provided with a thread that mates with the threaded section.

[0016] Preferably, the connector includes two columns, which are fixed on one of the bases and the other base is slidably mounted on the two columns. One of the columns is provided with an adjustment mechanism for adjusting the distance between the two bases.

[0017] Preferably, the adjusting mechanism includes a rotating sleeve, which is rotatably mounted on a base that slides with the column, and the rotating sleeve is threaded onto one of the columns.

[0018] The beneficial effects of this utility model are as follows:

[0019] This invention features two bases connected by connectors. The filter cartridge for filtering oil is fixed at both ends to the grooves of the two bases by multiple clamping blocks, forming a complete filter element structure. Moving the clamping blocks releases the restriction on the filter cartridge end, facilitating cartridge replacement without needing to replace the entire filter element structure, thus reducing operating costs. The locking rod, when rotated, moves the drive block, pushing the clamping blocks radially along the grooves. The arc-shaped sections of the clamping blocks then clamp the filter cartridge end, securing it in place. To replace the filter cartridge, the locking rod is rotated in the opposite direction, causing the drive block to engage with the clamping blocks. Under spring pressure, the straight section of the clamping block moves towards the center of the limiting platform, thus engaging the filter cartridge end. The rotating sleeve, when rotated, moves one base on the column, changing the distance between the two bases. This allows the invention to use filter cartridges of various lengths.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1:

[0032] like Figures 1 to 7 As shown, the oil separation filter structure provided in Embodiment 1 of this utility model includes two symmetrically arranged bases 1. Each base 1 has a circular groove 2 at its center. A limiting platform 8 is fixedly installed in the groove 2 by bolts. The axis of the limiting platform 8 is collinear with the axis of the groove 2. The limiting platform 8 has six sliding grooves 11 evenly distributed around its circumference. A straight section 10 is slidably installed in each sliding groove 11. An arc-shaped section 9 is fixed to the end of the straight section 10 away from the limiting platform 8. The straight section 10 and the arc-shaped section 9 form a retaining block 3. The two bases 1 are connected by two columns 22 as connectors 4. One base 1 is fixed to the bottom of the column 22, and the other base 1 is slidably sleeved on the column 22.

[0033] The filter cartridge 5 can be an existing paper filter cartridge 5 used for oil and gas filtration. Both ends of the filter cartridge 5 are embedded in the grooves 2 of the two bases 1. When the straight section 10 moves in the sliding groove 11, the arc-shaped section 9 of the pressing block 3 is driven by the straight section 10, thus pressing tightly against the end of the filter cartridge 5, forming a sealed contact with the groove wall 2. At this time, the filter cartridge 5 and the two bases 1 enclose a closed filtration chamber 6. To enhance the pressing effect of the arc-shaped section 9 on the filter cartridge 5, adjacent arc-shaped sections 9 are staggered vertically and have overlapping areas, ensuring complete pressing against the end of the filter cartridge 5.

[0034] An air inlet 7 is provided on the base 1 at the lower end, which can introduce the oil-gas mixture into the filter chamber 6. After being separated by the filter cartridge 5, the oil is retained by the filter cartridge 5, and the gas is discharged after passing through the filter cartridge 5.

[0035] A connecting sleeve 24, which covers the air inlet 7, is also fixed on the lower base 1. The connecting sleeve 24 can be fixed on the air inlet pipe of the filter. This utility model achieves quick disassembly and assembly of the filter cartridge 5 by the radial displacement of the clamping block 3, avoiding the replacement of the entire filter element and significantly reducing the maintenance cost of the filter.

[0036] Example 2:

[0037] like Figure 6 As shown, based on Embodiment 1, to facilitate control of the movement of the clamping block 3, this utility model adds a through hole 12 in the middle of the limiting platform 8. A drive block 13, capable of axial movement along the axis of the groove 2, is installed inside the through hole 12. The end of the straight section 10 of the clamping block 3 extends into the through hole 12 and contacts the conical surface of the drive block 13. The locking rod 19 passes through the stepped hole 18 on the base 1 and is fixedly connected to the drive block 13. The locking rod 19 is also stepped. A first sealing ring 20 is fitted on the smaller diameter section of the locking rod 19. The first sealing ring 20 can slide to seal the gap between the locking rod 19 and the stepped hole 18, effectively preventing oil and gas leakage. A threaded section is provided on the larger diameter section of the stepped hole 18, which engages with the threaded section of the larger diameter section of the locking rod 19.

[0038] When the locking rod 19 is rotated, under the action of the thread, the locking rod 19 moves axially along the stepped hole 18, thereby driving the block 13 to move axially along the through hole 12. The conical surface of the driving block 13 pushes the straight section 10 to slide outward along the slide groove 11, so that the arc section 9 presses against the end of the filter cylinder 5.

[0039] To facilitate the repositioning of the clamping block 3, this invention also incorporates a spring-loaded structure. Specifically, the spring-loaded structure includes six guide rods 14 fixed to the circumferential sidewall of the limiting platform 8. A baffle 15 is fixed to the end of each guide rod 14 away from the limiting platform 8. A spring 17 is sleeved on the guide rod 14 between the baffle 15 and the limiting platform 8, and a connecting plate 16 is sleeved on the guide rod 14 between the spring 17 and the limiting platform 8. The connecting plate 16 is fixedly connected to the radial section 10. Thus, when the locking rod 19 is rotated in the reverse direction, the driving block 13 moves away from the radial section 10, releasing the clamping force on the radial section 10. At this time, the spring 17 on the guide rod 14 pushes the connecting plate 16 to move back to the limiting platform 8, causing the clamping block 3 to retract.

[0040] With the above settings, rotating the locking rod 19 can drive multiple clamping blocks 3 to clamp the filter cartridge 5 or release the limit on the filter cartridge 5, greatly improving the efficiency of disassembly and assembly.

[0041] Example 3:

[0042] like Figure 7 As shown, based on Embodiments 1 and 2, this utility model further adds a threaded adjustment mechanism to the column 22 of the connecting member 4, including a rotating sleeve 23 rotatably mounted on the outside of the slidable base 1. The rotating sleeve 23 is sleeved on one of the columns 22, and the inner wall of the rotating sleeve 23 is threadedly engaged with the column 22. When the rotating sleeve 23 is rotated, the slidable base 1 is driven to move axially along the column 22 through the thread action, thereby changing the distance between the two bases 1. When changing filter cartridges 5 of different lengths, only the rotating sleeve 23 needs to be rotated to adjust the distance between the bases 1. The two columns 22 and the slidable base 1 are connected in a sliding seal by a second sealing ring 21 to prevent oil and gas leakage.

[0043] The above settings break through the limitations of fixed filter cartridge length in traditional systems, making it compatible with various sizes of filter cartridges and significantly expanding the applicable scenarios.

[0044] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
