Description

Technical Field

[0001] This utility model relates to the field of oil-gas separators, and in particular to a combined oil-gas separator. Background Technology

[0002] An oil-gas separator is a device that uses physical processes such as gravity settling, centrifugal force, and filtration to separate oil and gas in an oil-gas mixture. It can purify gas and recover oil, and is widely used in petrochemical, internal combustion engine and other fields. Combined oil-gas separators, by integrating multiple separation principles, can make up for the limitations of single separation methods. They can improve the separation efficiency of oil droplets of different particle sizes, balance energy consumption and equipment life, and meet special requirements such as environmental protection and oil recovery. Therefore, they have significant advantages in high-requirement scenarios.

[0003] The core of existing combined oil-gas separators is to achieve progressive separation of oil-gas mixtures by integrating multiple separation principles. Its working logic is to process in stages, with each part performing its own function: first, centrifugal separation, gravity sedimentation, or inertial impaction are used to selectively separate larger oil droplets that are easier to process, reducing the load on subsequent processing; then, filtration separation, adsorption separation, and other means are used to capture the remaining small oil droplets, ultimately achieving efficient separation of oil and gas. This combination can ensure the overall separation efficiency while balancing equipment energy consumption, lifespan, and volume, in order to adapt to the oil and gas characteristics and performance requirements of different scenarios.

[0004] However, in the practical application of combined oil-gas separators, the complexity of filter replacement remains a pain point that urgently needs to be addressed. In current equipment designs, filters are often nested deep inside the tank, tightly connected to components such as centrifugal separation chambers and settling channels. When replacing them, the equipment must first be shut down and the internal pressure released, then multiple sets of flange bolts must be disassembled, auxiliary structures such as guide plates must be removed, and even residual oil and gas must be vented. The entire process often requires the collaboration of multiple technicians and takes a considerable amount of time to complete. This cumbersome process not only leads to excessive downtime and disrupts the production line rhythm, but also causes wear on seals due to frequent disassembly, increasing the risk of gas leakage. In the long run, this reduces the continuous operating efficiency of the equipment and increases maintenance costs, contradicting the design intention of combined separators to pursue high efficiency and stability. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a combined oil-gas separator, which aims to improve the problem in the prior art where complicated operations are required to remove and replace the filter screen from the inside of the tank during equipment use.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a combined oil-gas separator, comprising a tank, an identification block fixedly connected to the outer wall of the tank, an inlet / outlet liquid assembly provided on the outer wall of the tank, a sealing cover slidably connected to the top of the tank, a filter screen slidably connected inside the tank, multiple connecting rods fixedly connected to the top of the filter screen, a connecting block fixedly connected to the top of each connecting rod, a limit block fixedly connected to the bottom of each connecting block, and multiple fixing components provided inside the tank;

[0007] Each of the fixing components includes a fixing pin, a limiting plate, and a pull ring. The outer wall of the fixing pin is slidably connected to the inside of the tank body and the limiting block. One side of the limiting plate is fixedly connected to one end of the fixing pin, and one end of the pull ring is fixedly connected to one side of the limiting plate.

[0008] As a further description of the above technical solution:

[0009] The liquid inlet / outlet assembly includes a liquid inlet pipe, an air outlet pipe, and an oil outlet pipe. One end of the liquid inlet pipe is fixedly connected to the outer wall of the tank body, one end of the air outlet pipe is fixedly connected to the outer wall of the tank body, and the top end of the oil outlet pipe is fixedly connected to the bottom of the tank body.

[0010] As a further description of the above technical solution:

[0011] The outer wall of the sealing cover is fixedly connected with multiple connecting strips, and each connecting strip is fixedly connected to a mating strip on one side.

[0012] As a further description of the above technical solution:

[0013] Each of the mating strips is fixedly connected to both sides, and each of the mating strips has a fixing groove on one side.

[0014] As a further description of the above technical solution:

[0015] The top of the tank is fixedly connected to multiple docking blocks, and each docking block has multiple sliding grooves inside.

[0016] As a further description of the above technical solution:

[0017] Each of the docking blocks has a movable groove inside, and an elastic plate is fixedly connected inside each of the docking blocks.

[0018] As a further description of the above technical solution:

[0020] As a further description of the above technical solution:

[0021] The bottom end of each of the said docking strips is slidably connected to the inside of the docking block, and the outer wall of each of the said limiting strips is slidably connected to the inside of the sliding groove.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, first hold the pull ring and pull it outward to disengage the fixing pin from the tank and the limiting block, thereby unlocking the connecting rod. Then, hold the connecting rod and lift it upward, while the filter screen moves along with the connecting rod, thus removing the filter screen from the tank. This achieves the effect of easily removing and replacing the filter screen from the tank during equipment use, avoiding the problem of needing complicated operations to remove and replace the filter screen from the tank during equipment use, thereby improving the efficiency of the combined oil-gas separator.

[0024] 2. In this utility model, the limiting strips on both sides of the connecting strip around the sealing cover are first aligned with the sliding groove inside the connecting block. Then, they are fastened together so that one side of the connecting strip presses the fixing strip and retracts it into the moving groove. When the connecting strip is fully inside the connecting block, the fixing strip pops out under the action of the elastic plate and slides into the fixing groove. This achieves the effect of easily fastening the sealing cover to the top of the tank during equipment use, avoiding the problem of complicated operations required to open the sealing cover and then operate inside the tank during equipment use, thereby improving the practicality of the combined oil-gas separator.

[0033] 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.

[0034] Reference Figures 1-3 An embodiment of this utility model provides a combined oil-gas separator, including a tank 1. A marking block 5 is fixedly connected to the outer wall of the tank 1 for marking the tank 1. An inlet / outlet liquid assembly is provided on the outer wall of the tank 1 for liquid inlet / outlet. A sealing cover 6 is slidably connected to the top of the tank 1 for sealing the tank 1. A filter screen 7 is slidably connected inside the tank 1 for filtering oil-gas mixtures. Multiple connecting rods 8 are fixedly connected to the top of the filter screen 7 for connecting the filter screen 7. A connecting block 9 is fixedly connected to the top of each connecting rod 8 for connecting the tank 1 and the connecting rod 8. A limit block 10 is fixedly connected to the bottom of each connecting block 9 to restrict the movement of the connecting rod 8. Multiple fixing components are provided inside the tank 1 for fixing the connecting rod 8 to prevent it from shaking.

[0035] Each fixing component includes a fixing pin 11, a limiting plate 12, and a pull ring 13. The outer wall of the fixing pin 11 is slidably connected to the tank body 1 and the inside of the limiting block 10 to fix the limiting block 10 inside the tank body 1. One side of the limiting plate 12 is fixedly connected to one end of the fixing pin 11 to limit the movement range of the fixing pin 11. One end of the pull ring 13 is fixedly connected to one side of the limiting plate 12 to drive the fixing pin 11 to move. The liquid inlet and outlet assembly includes a liquid inlet pipe 2, a gas outlet pipe 3, and an oil outlet pipe 4. One end of the liquid inlet pipe 2 is fixedly connected to the outer wall of the tank body 1 to allow the oil-gas mixture to flow in. One end of the gas outlet pipe 3 is fixedly connected to the outer wall of the tank body 1 to discharge gas. The top end of the oil outlet pipe 4 is fixedly connected to the bottom of the tank body 1 to discharge oil.

[0036] Specifically, during operation, first grasp the pull ring 13 and pull it outward with a little force. At this time, the fixing pin 11 connected to the pull ring 13 will be driven, causing it to smoothly disengage from the inside of the tank body 1 and the slot of the limiting block 10. The originally locked connecting rod 8 will then be released from its locked state. Next, grasp the connecting rod 8 with both hands and lift it vertically upward slowly. The filter screen 7 installed at the lower end of the connecting rod 8 will then smoothly rise along the inner wall of the tank body 1 in sync with the connecting rod 8. The entire process does not require contact with other parts inside the tank body 1. It only takes tens of seconds to completely and smoothly remove the oil-stained filter screen 7 from the inside of the tank body 1, which is both labor-saving and avoids collisions between parts.

[0037] Reference Figures 4-6 Multiple connecting strips 14 are fixedly connected to the outer wall of the sealing cover 6 for connecting mating strips 15. Each connecting strip 14 has a mating strip 15 fixedly connected to one side, which cooperates with the mating block 18 to fix the sealing cover 6 to the top of the tank body 1. Each mating strip 15 has a limit strip 16 fixedly connected to both sides to limit the movement range of the mating strip 15. Each mating strip 15 has a fixing groove 17 on one side to accommodate the fixing strip 22. Multiple mating blocks 18 are fixedly connected to the top of the tank body 1, which cooperate with the mating strips 15 to fix the sealing cover 6 to the top of the tank body 1. Each mating block 18 has multiple... Each sliding groove 19 is used to accommodate the limiting strip 16. Each docking block 18 has a moving groove 20 inside to accommodate the elastic plate 21 and the fixing strip 22. Each docking block 18 has an elastic plate 21 fixedly connected inside to provide elastic force for the fixing strip 22. Each elastic plate 21 has a fixing strip 22 fixedly connected to one side to fix the docking strip 15 and the docking block 18. The outer wall of each fixing strip 22 is slidably connected to the inside of the fixing groove 17. The bottom end of each docking strip 15 is slidably connected to the inside of the docking block 18. The outer wall of each limiting strip 16 is slidably connected to the inside of the sliding groove 19.

[0038] Specifically, during installation, first align the limiting strips 16 on both sides of the connecting strip 15 around the sealing cover 6 precisely with the sliding groove 19 inside the connecting block 18 at the port of the tank body 1. Then, press the edge of the sealing cover 6 with both hands and apply force evenly to make the connecting strip 15 and the connecting block 18 tightly engage. During the process, you can clearly feel the connecting strip 15 slowly squeezing the fixing strip 22 inside the connecting block 18, forcing the fixing strip 22 to retract inward along the moving groove 20. When the connecting strip 15 is fully embedded inside the connecting block 18, the compressed elastic plate 21 quickly rebounds, pushing the fixing strip 22 out of the moving groove 20 and precisely sliding into the fixing groove 17 on the side of the connecting strip 15. At this time, the sealing cover 6 is firmly locked to the tank body 1, and the installation process is stable and efficient.

[0039] Working principle: When using the combined oil-gas separator, first open the sealing cover 6, then start replacing the filter screen 7. Hold the pull ring 13 and pull it outward to disengage the fixing pin 11 from the tank body 1 and the limiting block 10, thereby unlocking the connecting rod 8. Then hold the connecting rod 8 and lift it upward. At the same time, the filter screen 7 moves with the connecting rod 8, thereby removing the filter screen 7 from the tank body 1. Then install the new filter screen 7 back into the tank body 1. Then fasten the sealing cover 6 back on. First, align the limiting strips 16 on both sides of the connecting strip 15 around the sealing cover 6 with the sliding groove 19 inside the connecting block 18. Then, they are interlocked so that one side of the connecting strip 15 squeezes the fixing strip 22 and retracts it into the moving groove 20. When the connecting strip 15 is fully inside the connecting block 18, the fixing strip 22 pops out under the action of the elastic plate 21 and slides into the fixing groove 17, thereby fixing the sealing cover 6 to the top of the tank body 1, thus completing the replacement of the filter screen 7.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
