Description

Technical Field

[0001] This utility model relates to the field of oil-water separator technology, and in particular to an oil-water separator with a quick-replaceable filter element. Background Technology

[0002] Oil-water separators are widely used in automotive diesel engines, industrial hydraulic systems, and marine equipment. They are primarily used to effectively separate water and impurities from fuel or lubricating oil to ensure the stable operation of the fuel or lubrication system. The presence of water in oil can cause corrosion of metal parts, reduced lubrication performance, and even equipment malfunctions. Therefore, oil-water separators have become critical components in various operating conditions.

[0003] Existing oil-water separators generally suffer from inconvenience in filter element replacement structures. In particular, some devices use an external filter element connected to the oil-water separator housing via threads. In actual use, users need to hold the filter element cover with both hands, apply considerable rotational force, and frequently rotate the cover to remove the filter element. This is not only time-consuming and laborious, but also seriously affects maintenance efficiency and ease of use, making it difficult to meet the application requirements of rapid maintenance and high-frequency replacement. Therefore, there is an urgent need to provide a structurally optimized and easily disassembled oil-water separator filter element replacement solution to improve the user experience and work efficiency. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose an oil-water separator with a quick filter element replacement function, so as to solve the problem that users need to hold the filter element cover with both hands, apply a heavy rotational force and frequently rotate the filter element cover to remove the filter element. This is not only time-consuming and laborious, but also seriously affects maintenance efficiency and ease of use.

[0005] To achieve the above objectives, this utility model provides an oil-water separator with a quick-replaceable filter element, comprising an oil-water separator, an inlet pipe and an outlet pipe respectively connected to both sides of the oil-water separator, a connecting pipe connected to the bottom of the oil-water separator, a separation tank provided at the bottom of the connecting pipe, a filter element provided inside the separation tank, a water storage box connected to the bottom of the separation tank, and a quick-release mechanism for disassembling the separation tank and removing the filter element provided on the outer wall of the connecting pipe.

[0006] Preferably, the quick-release mechanism includes a movable ring slidably connected to the outer wall of the connecting tube, a compression spring fixedly connected between the side wall of the movable ring and the outer wall of the connecting tube, the compression spring being sleeved on the outer wall of the connecting tube, a plurality of equidistant and evenly distributed receiving grooves being provided on the side of the movable ring near the connecting tube, a plurality of equidistant and evenly distributed ball grooves being provided on the inner wall of the connecting tube, a fixed ball being placed inside each ball groove, the fixed ball being positioned between the ball groove and the receiving groove when entering the ball groove, and a plurality of equidistant and evenly distributed limiting arc grooves being provided on the top outer wall of the separating tank.

[0007] Preferably, a rotating ring is rotatably connected to the outer wall of the moving ring, and limiting grooves are formed on both sides of the rotating ring. Fixed rods are fixedly connected to both sides of the separation tank. Rotating plates are rotatably connected to the opposite ends of the two fixed rods. Tension springs are fixedly connected between the two rotating plates near the outer wall of the separation tank. A clamping plate is fixedly connected to the top of the rotating plate. The side wall of the clamping plate extends into the inner wall of the limiting groove. A limiting plate is fixedly connected to the side wall of the fixed rod. The side wall of the limiting plate is in contact with the side wall of the rotating plate.

[0008] Preferably, the top and sides of the card plate are both arc-shaped, and the inner wall of the limiting groove is adapted to the outer wall of the card plate.

[0009] Preferably, a flow divider is fixedly connected inside the connecting pipe, and a discharge hole is provided at the top center of the flow divider. Multiple equidistant and evenly distributed feed holes are provided at the top edge of the flow divider near the discharge hole.

[0010] Preferably, the feed pipe and the plurality of feed holes are interconnected, and the discharge pipe and the discharge holes are interconnected.

[0011] Preferably, a sealing ring for preventing leakage is provided between the top of the separator and the bottom of the diversion plate.

[0012] The beneficial effects of this utility model are:

[0013] This oil-water separator with a quick-release filter element effectively solves the problems of frequent rotation of the outer cover and laborious disassembly required by existing technologies where the filter element is connected by threads. Through the cooperation of a rotating ring and a limiting groove, the locking plate is pushed out of the limiting groove, and the rotating plate rotates around the fixed rod to stretch the tension spring, thus initially releasing the limiting position on the separator tank. Subsequently, the rotating ring further pushes the moving ring to slide on the outer wall of the connecting pipe and compress the spring, causing the receiving groove to move to align with the ball groove, releasing the limiting position on the fixed ball. The fixed ball automatically rolls into the receiving space formed by the ball groove and the receiving groove, ultimately achieving complete unlocking of the separator tank. This structure avoids the problem of users having to forcefully twist the filter element cover in traditional structures, enabling quick filter element replacement and cleaning with a single hand rotation and push. This significantly improves filter element replacement efficiency and ease of use, making it suitable for applications with high requirements for maintenance response speed and operational convenience.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0023] like Figures 1 to 4 As shown, an oil-water separator with a quick-replaceable filter element includes an oil-water separator 1. An inlet pipe 2 and an outlet pipe 3 are respectively connected to both sides of the oil-water separator 1. A connecting pipe 4 is connected to the bottom of the oil-water separator 1. A separation tank 5 is provided at the bottom of the connecting pipe 4. A filter element 6 is provided inside the separation tank 5. A water storage box 7 is connected to the bottom of the separation tank 5. A quick-release mechanism for disassembling the separation tank 5 and removing the filter element 6 is provided on the outer wall of the connecting pipe 4.

[0024] Further, see attached document. Figures 2 to 4As shown, the quick-release mechanism includes a movable ring 8 slidably connected to the outer wall of the connecting pipe 4. A compression spring 9 is fixedly connected between the side wall of the movable ring 8 and the outer wall of the connecting pipe 4. The compression spring 9 is sleeved on the outer wall of the connecting pipe 4. The movable ring 8 has multiple evenly distributed receiving grooves 10 on the side near the connecting pipe 4. The inner wall of the connecting pipe 4 has multiple evenly distributed ball grooves 11. Fixed balls 12 are placed inside the ball grooves 11. When the fixed balls 12 enter the ball grooves 11, they are positioned between the ball grooves 11 and the receiving grooves 10. The top outer wall of the separation tank 5 has multiple evenly distributed limiting arc-shaped grooves 13. A rotating ring 14 is rotatably connected to the outer wall of the movable ring 8. Both sides of the rotating ring 14 have... The limiting groove 15 is fixedly connected to both sides of the separation tank 5. The two fixed rods 16 are rotatably connected to the opposite ends of the two fixed rods 16. The two rotating plates 17 are fixedly connected to the outer wall of the separation tank 5. The top of the rotating plate 17 is fixedly connected to the clamping plate 19. The side wall of the clamping plate 19 extends into the inner wall of the limiting groove 15. The side wall of the fixed rod 16 is fixedly connected to the limiting plate 20. The side wall of the limiting plate 20 is in contact with the side wall of the rotating plate 17. The limiting plate 20 limits the rotation angle of the rotating plate 17 to avoid excessive rotation affecting the installation of the separation tank 5. The top and sides of the clamping plate 19 are arc-shaped. The inner wall of the limiting groove 15 and the outer wall of the clamping plate 19 are adapted to each other.

[0025] First, the operator pinches the rotating ring 14 and rotates it. During the rotation, the rotating ring 14 drives the limiting groove 15 on it to rotate synchronously. Since the two sides of the clamping plate 19 are arc-shaped, when the rotation drives the limiting groove 15, the arc-shaped clamping plate 19 is gradually pushed out of the limiting groove 15. The clamping plate 19 then drives the rotating plate 17 to rotate around one end of the fixed rod 16, and at the same time stretches the connected tension spring 18, thereby realizing the initial release of the limiting of the separation tank 5.

[0026] Continue to pinch the rotating ring 14 and push it towards the compression spring 9. At this time, the rotating ring 14 drives the moving ring 8 connected to it to slide axially along the outer wall of the connecting pipe 4. During the pushing process, the compression spring 9 is compressed, causing the moving ring 8 to drive the receiving groove 10 to move further to the state of being aligned with the ball groove 11. When the moving ring 8 moves to the designated position, its inner wall no longer applies a limiting force to the fixed ball 12. The fixed ball 12 will roll back into the ball groove 11 without external pressure. At this time, the ball groove 11 and the receiving groove 10 together form a receiving space, so that the fixed ball 12 is completely freed from the limiting effect on the separation tank 5. Through the operation of the above structure, the separation tank 5 can be quickly unlocked. The operator can easily take out the separation tank 5 and replace or clean the filter element 6 installed inside it, which significantly improves the maintenance efficiency and ease of use of the filter element 6.

[0027] By incorporating a quick-release structure, the problem of frequent rotation of the outer cover and laborious disassembly required for the filter element 6 via threaded connection in existing technologies can be effectively solved. The rotating ring 14, in conjunction with the limiting groove 15, drives the retaining plate 19 out of the limiting groove 15 and drives the rotating plate 17 to rotate around the fixed rod 16 to stretch the tension spring 18, thus initially releasing the limiting position on the separator tank 5. Subsequently, the rotating ring 14 further pushes the moving ring 8 to slide on the outer wall of the connecting pipe 4 and compresses the spring 9, causing the receiving groove 10 to move to align with the ball groove 11, releasing the limiting position on the fixed ball 12. The fixed ball 12 automatically rolls into the receiving space formed by the ball groove 11 and the receiving groove 10, ultimately achieving complete unlocking of the separator tank 5. This structure avoids the problem of users having to forcefully twist the filter element cover in traditional structures, enabling quick replacement and cleaning of the filter element 6 with a single hand rotation and push, significantly improving the replacement efficiency and ease of use of the filter element 6. It is suitable for application scenarios with high requirements for maintenance response speed and operational convenience.

[0028] Further, see attached document. Figure 2 As shown, a flow divider plate 21 is fixedly connected inside the connecting pipe 4. A discharge hole 22 is opened in the middle of the top of the flow divider plate 21. Multiple equally spaced and evenly distributed feed holes 23 are opened on the top of the flow divider plate 21 near the edge of the discharge hole 22. The feed pipe 2 and each feed hole 23 are interconnected. The discharge pipe 3 is interconnected with the discharge hole 22. Through the connection between the feed pipe 2 and the feed hole 23, the oil enters the periphery of the filter element 6 through the feed hole 23. The filter element 6 filters out water molecules and impurities in the oil. The filtered oil will flow into the discharge pipe 3 through the connection between the discharge pipe 3 and the discharge hole 22.

[0029] Further, see attached document. Figure 2 As shown, a sealing ring 24 for preventing leakage is provided between the top of the separator 5 and the bottom of the diversion plate 21. The sealing ring 24 prevents the oil inside the separator 5 from leaking out during use between the separator 5 and the connecting pipe 4.
