Description

Technical Field

[0001] This utility model relates to the field of coalescing separator technology, specifically a skid-mounted coalescing separator with a fully detachable filter element. Background Technology

[0002] Coalescing separators are primarily designed for liquid-liquid separation. They contain two types of filter elements: a coalescing filter element and a separating filter element. For example, in an oil dehydration system, after the oil flows into the coalescing separator, it first passes through the coalescing filter element. This element removes solid impurities and coalesces tiny water droplets into larger droplets. Most of the coalesced water droplets are separated from the oil by gravity and settle into a collection tank. The oil then flows through the separating filter element. Due to the separating filter element's excellent oleophilic and hydrophobic properties, water is further separated. Finally, clean, water-free oil flows out of the coalescing separator.

[0003] The related technology (publication number: CN219111052U) discloses a high-efficiency filter coalescing separator for aviation kerosene. The disclosed technical solution is that the coalescing separator has the functions of filtration, coalescence and separation. The integrated design can reduce the original four devices to two devices, which greatly reduces the equipment investment cost and reduces the maintenance and filter replacement workload by half, which has great economic significance.

[0004] The above-disclosed technical solutions reveal the following problems: the filter elements inside the coalescing separator need to be replaced after prolonged use to ensure filtration efficiency. For coalescing separators with multiple filter elements inside, the filter elements need to be removed step by step during replacement, making the replacement process cumbersome. To address this, we propose a novel skid-mounted coalescing separator with a fully detachable filter element.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background section of this application, and therefore may include prior art information that does not constitute prior art information known to those skilled in the art. Summary of the Invention

[0006] This utility model aims to solve at least one of the technical problems existing in the prior art or related technologies. To address the issue of filter element replacement in the prior art, this utility model provides a skid-mounted coalescing separator with a fully detachable filter element. It employs a filter element replacement structure combined with a filter element adapter structure to facilitate filter element replacement. The specific technical solution is as follows:

[0007] A skid-mounted coalescing separator with a fully detachable filter element includes a separation tank. A base frame and a top frame are symmetrically embedded at both ends of the inner cavity of the separation tank. The base frame and the top frame are connected by a telescopic member, and the telescopic member and the top frame are engaged by an elastic deformation locking member. The base frame has a liquid inlet hole for docking with the filter element. The base frame also has directional guide grooves located on both sides of the liquid inlet hole. A four-bar hinge shaft is slidably mounted within the inner cavity of the directional guide groove. A locking clip is mounted on the hinge shaft of the four-bar linkage above the base frame. A linkage locking assembly that drives all four bars to fold simultaneously is located at the bottom of the base frame.

[0008] In the above technical solution, the linkage locking assembly includes a threaded post fixedly installed at the bottom of the base frame. The outer wall of the threaded post is threaded with a tapered push seat. A force-bearing drive seat is provided on the hinge shaft of the four-link rod near the center of the base frame, and the force-bearing drive seat is located below the base frame.

[0009] The outer walls of the four-bar linkage are symmetrically fitted with limiting plates that fit against both sides of the base frame.

[0010] The inner wall of the locking clip is evenly provided with clips.

[0011] The elastic deformation engaging component includes an elastic retractable component fixedly installed on the top of the telescopic component's outer sleeve, and the top frame has a locking hole opposite to the elastic retractable component.

[0012] The top edge of the top frame is provided with evenly spaced connecting holes. The top and bottom of the inner wall of the separation tank are both circumferentially fixed with mating seats, and the mating seats on the top of the inner wall of the separation tank correspond to the connecting holes.

[0013] The base frame has connecting seats that are evenly fixedly installed on its outer circumferential wall, corresponding to the docking seats.

[0014] Both the base frame and the top frame are equipped with snap-fit ​​springs that are evenly inclined in the circumferential direction.

[0015] The base frame is evenly perforated circumferentially.

[0016] Compared with the prior art, the beneficial effects of this utility model are: the skid-mounted, fully detachable filter element coalescing separator:

[0017] 1. When installing the filter element, the linkage locking assembly causes one hinge shaft of each of the four links to slide against the inner wall of the guide groove, causing the four links to fold. This, in turn, causes two locking clips to engage with the outer wall of the filter element, locking all the filter elements in place. This makes the filter element installation and removal process more convenient, thereby improving the efficiency of the filter element replacement process.

[0018] 2. When all four links are folded simultaneously, the conical pusher is screwed on the threaded column. As the conical pusher moves vertically, it pushes multiple circumferential force-driven seats to move. This causes the force-driven seats to drive the hinge shafts of the four links to slide on the inner wall of the directional guide groove, thereby folding the four links simultaneously and fixing all filter elements at the same time. This makes the operation more convenient. During the operation, the distance between the two locking clips can be adjusted according to the specifications of the filter elements, thus making it suitable for the installation of filter elements of different specifications.

[0019] Third, the two limiting plates slide against the upper and lower surfaces of the base frame respectively. The two limiting plates ensure the stability of the movement direction of the four-bar hinge shaft and prevent the hinge shaft of the four-bar from shifting, thereby ensuring the stability of the filter element installation.

[0020] 4. After the filter element is installed between the base frame and the top frame, the base frame drives the telescopic component to retract, causing the elastic retractable component on the telescopic component to deform and generate elastic force when it passes through the locking hole. After the elastic retractable component passes through the locking hole, the elastic force is used to make the elastic retractable component unfold and lock into the top of the top frame, thereby fixing the base frame and the top frame, making the filter element installation operation more convenient.

[0021] 5. The base frame and top frame are respectively snapped into the upper and lower ends of the separator tank by the elastic deformation of the snap-fit ​​springs. The pre-installation of the snap-fit ​​springs facilitates the operation of the filter element replacement process. Attached Figure Description

Detailed Implementation

[0031] 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.

[0032] The following are specific implementation cases and appendices. Figure 1-8 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0033] A skid-mounted coalescing separator with a fully detachable filter element includes a separation tank 1. A base frame 2 and a top frame 3 are symmetrically embedded at both ends of the inner cavity of the separation tank 1, and the base frame 2 and top frame 3 are connected by a telescopic member 4. The telescopic member 4 is vertically fixedly installed at the top center of the base frame 2, and its movable end is vertically fixedly installed at the bottom center of the top frame 3, allowing the distance between the base frame 2 and the top frame 3 to be adjusted. An inlet 10 and an outlet 11 are fixedly embedded at the bottom of the separation tank 1. The inlet 10 connects to the coalescing filter element, and the outlet 11 connects to the separation filter element.

[0034] Both the liquid inlet 10 and the oil outlet 11 are sealed with plugs when not in use. The adjustable gap between the base frame 2 and the top frame 3 provides sufficient operating space for filter element installation, thus facilitating filter element installation and removal.

[0035] The telescopic component 4 and the top frame 3 are engaged by an elastic deformation locking member. The base frame 2 is embedded and installed at the bottom of the separator tank 1. Then, the top frame 3 is embedded at the top of the separator tank 1, so that the top frame 3 is engaged with the telescopic component 4 by the elastic deformation locking member, thereby fixing the top frame 3 and the base frame 2, ensuring the stability of the filter element inside the separator tank 1, and making the filter element installation and removal process more convenient.

[0036] The base frame 2 has an inlet hole 6 for docking with the filter element, and directional guide grooves 5 located on both sides of the inlet hole 6. Six inlet holes 6 are evenly spaced circumferentially on the base frame 2, arranged in a circumferential array with the center of the base frame 2 as the center. Directional guide grooves 5 are located on both sides of each inlet hole 6, aligned in a straight line. A hinge shaft of a four-bar linkage 7 is slidably mounted inside the directional guide groove 5. The four-bar linkage 7 consists of four rods hinged end-to-end, with each rod's ends rotatably connected to an adjacent rod via a hinge shaft. The two non-adjacent hinge shafts of the four-bar linkage 7 pass through the directional guide groove 5, and slide against the inner wall of the directional guide groove 5.

[0037] A locking clip 17 is provided on the hinge shaft of the four-link 7, located above the base frame 2. A linkage locking assembly is provided at the bottom of the base frame 2 to drive all four-link 7 to fold simultaneously. Arc-shaped locking clips 17 are fixedly installed at the top of the two adjacent hinge shafts of the four-link 7 by limiting plates 19. When the four-link 7 folds, the two ends of the two four-link 7 drive the two arc-shaped locking clips 17 to move relative to each other, so that the two arc-shaped locking clips 17 fix the filter element at the corresponding liquid inlet 6.

[0038] When installing the filter element, place it sequentially at the position corresponding to the inlet hole 6. Then, through the linkage locking assembly, slide one hinge shaft of each of the four-link 7 against the inner wall of the directional guide groove 5, causing the four-link 7 to fold. As the four-link 7 folds, the two hinge shafts move relative to each other, thereby causing the two locking clips 17 to engage with the outer wall of the filter element, locking all the filter elements at the same time. This makes the filter element installation and removal process more convenient, thereby improving the efficiency of the filter element replacement process.

[0039] The linkage locking assembly includes a threaded post 20 fixedly installed at the bottom of the base frame 2. A tapered pusher seat 8 is threadedly connected to the outer wall of the threaded post 20. A force-bearing drive seat 9 is installed on the hinge shaft of the four-link 7 near the center of the base frame 2, and the force-bearing drive seat 9 is located below the base frame 2. The threaded post 20 is vertically fixedly installed at the center of the bottom of the base frame 2. The tapered end of the tapered pusher seat 8 faces upwards, and a threaded hole for connecting to the threaded post 20 is opened at the center of the top of the tapered pusher seat 8. A spherical force-bearing drive seat 9 is fixedly installed at the bottom end of the innermost hinge shaft of each four-link 7. The spherical force-bearing drive seat 9 reduces the friction between the tapered pusher seat 8 and its surface.

[0040] When all four links 7 are folded simultaneously, the conical pusher seat 8 is screwed onto the threaded post 20, causing the slope of the conical pusher seat 8 to rotate and move. As the conical pusher seat 8 moves vertically, it pushes multiple circumferential force-driven seats 9 to move. This causes the force-driven seats 9 to drive the corresponding hinge shafts of the four links 7 to slide on the inner wall of the directional guide groove 5, thereby folding the four links 7 simultaneously and fixing all filter elements at the same time, facilitating the operation. During operation, the distance between the two locking clips 17 can be adjusted according to the filter element specifications, thus adapting to the installation of filter elements of different specifications.

[0041] Symmetrical limiting plates 19, which fit against both sides of the base frame 2, are sleeved on the outer wall of the four-link 7. Each limiting plate 19 is sleeved on the outer wall of the hinge shaft of the four-link 7 through through-holes penetrating the inner cavity, and slides against the upper and lower surfaces of the base frame 2. The two limiting plates 19 ensure the stability of the movement direction of the hinge shaft of the four-link 7, preventing positional deviation and thus ensuring the stability of the filter element installation.

[0042] It is worth noting that the inner wall of the locking clip 17 is evenly provided with clips 21. The clips 21 on the inner surface of the locking clip 17 improve the stability between the locking clip 17 and the filter element surface, prevent the filter element from detaching, and thus ensure the stability of the filter element after installation.

[0043] Furthermore, the elastic deformation engaging component includes an elastic retractable member 16 fixedly installed on the top of the outer casing of the telescopic member 4, and a locking hole 13 opposite to the elastic retractable member 16 is provided on the top frame 3. The elastic retractable member 16 is composed of three elastic clips, which elastically deform after converging towards the center. The elastic retractable member 16 is fixed to the top of the outer casing of the telescopic member 4 by a connecting rod whose length corresponds to the thickness of the top frame 3.

[0044] After the filter element is installed between the base frame 2 and the top frame 3, the base frame 2 drives the telescopic component 4 to retract, causing the elastic retractable component 16 on the telescopic component 4 to deform and generate elastic force when it passes through the locking hole 13. After the elastic retractable component 16 passes through the locking hole 13, the elastic force causes the elastic retractable component 16 to unfold and lock onto the top of the top frame 3, thereby fixing the base frame 2 and the top frame 3, making the filter element installation operation more convenient.

[0045] In addition, the top edge of the top frame 3 is evenly provided with connection holes 23, and the top and bottom of the inner wall of the separator 1 are circumferentially fixed with mating seats 14, with the mating seats 14 on the top of the inner wall of the separator 1 corresponding to the connection holes 23. After the top frame 3 is snapped into the top of the separator 1, the connection holes 23 are rotated to the corresponding positions of the mating seats 14, and then the top frame 3 is fixed to the top of the separator 1 with bolts, ensuring the stability of the top frame 3 after installation.

[0046] Furthermore, connecting seats 15, corresponding to the docking seat 14, are evenly fixedly installed on the outer circumference of the base frame 2. The base frame 2 is snapped onto the docking seat 14 via the connecting seats 15, thus securing the base frame 2 to the bottom of the separation tank 1. Then, the base frame 2 is rotated, causing the connecting seats 15 to rotate and position themselves opposite the docking seat 14. The connecting seats 15 are then fixed to the docking seat 14 with bolts, thereby fixing the base frame 2 to the bottom of the separation tank 1 and ensuring the stability of the base frame 2 after installation.

[0047] Both the base frame 2 and the top frame 3 are uniformly inclined with snap-fit ​​spring pieces 12. The base frame 2 and the top frame 3 are snapped into the upper and lower ends of the separator tank 1 by the elastic deformation of the snap-fit ​​spring pieces 12. The pre-installation of the snap-fit ​​spring pieces 12 facilitates the operation of the filter element replacement process.

[0048] The base frame 2 has evenly spaced perforations 22 on its circumference. This reduces the overall weight of the base frame 2, making installation easier.

[0049] This embodiment describes a skid-mounted coalescing separator with a fully detachable filter element. The working principle is as follows: First, the base frame 2 is snapped onto the bottom inner wall of the separator tank 1 using snap-fit ​​spring clips 12. Then, the base frame 2 is rotated so that the base frame 2 drives the connecting seat 15 to rotate to the position opposite to the docking seat 14. After that, the connecting seat 15 is fixed to the docking seat 14 with bolts.

[0050] Then place the polymer filter element at the corresponding inlet hole 6 so that the polymer filter element is aligned with the inlet 10. Place the separator filter element at the corresponding inlet hole 6 so that the separator filter element is aligned with the drain 11. Both the polymer filter element and the separator filter element are positioned between every two locking clips 17.

[0051] Then, the conical pusher seat 8 is screwed on the threaded column 20, causing the slope of the conical pusher seat 8 to rotate and move. As the conical pusher seat 8 moves in the vertical direction, it pushes multiple force-driven seats 9 in the circumferential direction to move. This causes the force-driven seats 9 to drive the hinge shafts corresponding to the four-link 7 to slide on the inner wall of the directional guide groove 5, thereby causing the four-link 7 to fold at the same time and fixing all filter elements at the same time.

[0052] Finally, the top frame 3 is moved towards the base frame 2, so that the top frame 3 is engaged with the elastic retractable part 16 on the telescopic part 4 through the connecting hole 23, thereby installing the filter element in the inner cavity of the separator tank 1.
