Description

Technical Field

[0001] This utility model relates to the field of separator technology, specifically to a dual separation structure for an oil-gas separator. Background Technology

[0002] An oil-gas separator is a device used to separate oil-gas mixtures. Because oil-gas separators have a relatively simple structure, the quality of separation is often low. Therefore, it is necessary to use a separator that can improve the separation quality.

[0003] Existing patent: CN202322797708.1 An oil-gas separator with dual filtration function, which can perform secondary separation of oil-gas mixture by setting an oil storage component in conjunction with a separation component and a sealing component, thereby improving the separation quality and efficiency. In use, the oil-gas mixture is first injected into the separator tank through the liquid inlet pipe. At this time, the oil-gas mixture passes through the separator umbrella and the oil dispersing cap in sequence under the action of gravity and falls to the bottom of the oil storage tank. The oil-gas mixture can be dually separated by the separator umbrella and the oil dispersing cap. At the same time, the oil is stored in the oil storage tank, and the gas rises and is discharged through the gas outlet pipe and the gas outlet head.

[0004] However, in this comparative example, the connection between the separator and the oil storage tank is fixed by welding. This fixing method makes it impossible to separate and disassemble the separator and the oil storage tank, which makes cleaning and maintenance inside the separator and the oil storage tank difficult, thus reducing the practicality of this comparative example.

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.

[0041] Please see Figure 1-4 This utility model provides a new technical solution: a dual separation structure for an oil-gas separator, including a separation tank 1, with an oil storage tank 2 disposed on the lower side of the separation tank 1;

[0042] Among them, the upper surface of the oil storage tank 2 is fixedly connected to a sliding tube 4 that communicates with its interior;

[0043] Among them, the lower surface of the separation tank 1 is fixedly connected to a fixed pipe 5 that communicates with its interior;

[0044] The oil storage tank 2 is equipped with a disassembly structure, which includes a fixing block 7, a sealing cover 6, a support frame 3, an electric push rod 8, a positioning block 9, a limit block 10, a support block 11, a spring 12, a support groove 13, a positioning groove 14, a limiting block 15, and a limiting groove 16.

[0045] Furthermore, two fixing blocks 7 are fixedly connected to the outer surface of the oil storage tank 2, and the two fixing blocks 7 are arranged in a mirror image.

[0046] Among them, two electric actuators 8 are fixedly connected to the upper surfaces of two fixed blocks 7;

[0047] Among them, two positioning blocks 9 are fixedly connected to the upper ends of two electric push rods 8;

[0048] The sliding tube 4 is slidably sleeved on the outer surface of the fixed tube 5, and a sealing ring is provided on the inner wall of the sliding tube 4.

[0049] Furthermore, two support grooves 13 are formed on the front surface of the two positioning blocks 9;

[0050] Among them, the support groove 13 extends out of the rear surface of the positioning block 9;

[0051] Two limiting blocks 10 are fixedly connected to the outer surface of the separation tank 1, and the two limiting blocks 10 are arranged in a mirror image.

[0052] Two positioning grooves 14 are formed on the upper surface of the two limiting blocks 10.

[0053] Furthermore, the positioning groove 14 extends beyond the lower surface of the limiting block 10, and the positioning groove 14 extends beyond the outer surface of the positioning block 9 on the side away from the separation tank 1.

[0054] The positioning block 9 is slidably connected to the positioning groove 14.

[0055] The sealing cap 6 is fixedly sleeved on the outer surface of the fixing tube 5;

[0056] A rubber pad is fixedly connected to the lower surface of the sealing cover 6, and the lower surface of the sealing cover 6 is in contact with the upper surface of the sliding tube 4.

[0057] Furthermore, the two limiting blocks 15 are slidably connected to the front surface of the two limiting blocks 10, and the two limiting blocks 15 slide through into the positioning groove 14;

[0058] The rear surface of the limiting block 15 is inclined.

[0059] The inclined surface of the limiting block 15 is slidably connected to the positioning block 9;

[0060] The support frame 3 is fixedly connected to the lower surface of the oil storage tank 2.

[0061] Furthermore, the two support blocks 11 are fixedly connected to the front surfaces of the two limiting blocks 15;

[0062] Four springs 12 are fixedly connected to the rear surface of the two limiting blocks 15;

[0063] The rear ends of the four springs 12 are fixedly connected to the front surface of the limiting block 10.

[0064] Furthermore, when connecting the separator tank 1 and the oil storage tank 2, the positioning block 9 is located on the upper side of the separator tank 1. The fixed tube 5 is slid into the sliding tube 4, so that the lower surface of the sealing cover 6 contacts the upper surface of the sliding tube 4. At this time, the electric push rod 8 is activated, and the electric push rod 8 drives the positioning block 9 to move up and down. When the positioning block 9 moves upward, it will slide into the positioning groove 14, and the upper surface of the positioning block 9 will push the inclined surface of the limiting block 15, pushing the limiting block 15 to move away from the limiting block 10. During this process, the spring 12 is stretched, causing the spring 12 to deform. When the limiting groove 16 and the limiting block 15 are at the same level, under the action of the release force of the spring 12, the limiting block 15 is pushed to slide into the groove 14. Inside the support groove 13, the limiting block 15 cooperates with the support groove 13 to restrict the positioning block 9, so that the positioning block 9 will not move downward relative to the limiting block 10. Then, the electric push rod 8 is activated to drive the positioning block 9 to move downward. The positioning block 9 exerts a downward force on the limiting block 10, which drives the separator tank 1 to connect downward with the oil storage tank 2, and drives the sealing cover 6 to contact the upper end of the sliding tube 4 tightly. The operation is convenient and no tools are needed during the installation process. This facilitates the cleaning and maintenance of the separator tank 1 and the oil storage tank 2 in the dual separation structure of the oil-gas separator. It also makes the seal between the fixed tube 5 and the sliding tube 4 tighter, making the connection between the separator tank 1 and the oil storage tank 2 more convenient, thereby increasing the stability and practicality of the dual separation structure of the oil-gas separator.

[0065] As described above, when the separator tank 1 and the oil storage tank 2 are needed, the two support blocks 11 need to be pulled out, so that the two support blocks 11 drive the two limiting blocks 15 to slide out of the support groove 13. At this time, the electric push rod 8 can be activated to slide the positioning block 9 out of the positioning groove 14. Then, the separator tank 1 is moved upward, and the separator tank 1 and the oil storage tank 2 are disassembled. The disassembly is convenient and quick, thereby increasing the installation and disassembly efficiency of the dual separation structure of the oil-gas separator. This also facilitates the cleaning and maintenance of the separator tank 1 and the oil storage tank 2 in the dual separation structure of the oil-gas separator, thereby increasing the practicality of the dual separation structure of the oil-gas separator.

[0066] Furthermore, the separator 1 includes an oil-dispersing cap, a separator umbrella, an inlet pipe, and an outlet pipe, while the oil storage tank 2 includes an oil storage tank, a second limiting pipe, an oil outlet pipe, a valve, a solenoid, and a first limiting pipe. When separating the oil-gas mixture, the oil-gas mixture is first injected into the separator through the inlet pipe. Under the action of gravity, the oil-gas mixture passes through the separator umbrella, the oil-dispersing cap, and the second limiting pipe in sequence and falls to the bottom of the oil storage tank for storage. Thus, the oil-gas mixture can be doubly separated through the separator umbrella and the oil-dispersing cap. The separator 1 and the oil storage tank 2 are existing technologies in the publicly disclosed patent: CN202322797708.1, "An Oil-Gas Separator with Dual Filtration Function," and their working principle is also existing technology, which will not be elaborated here.

[0067] Working principle: When the device is in use, the positioning block 9 is located on the upper side of the separating tank 1 when the separating tank 1 and the oil storage tank 2 are connected. The fixed tube 5 is slid into the sliding tube 4, so that the lower surface of the sealing cover 6 contacts the upper surface of the sliding tube 4. At this time, the electric push rod 8 is activated, which drives the positioning block 9 to move up and down. When the positioning block 9 moves upward, it slides into the positioning groove 14, and the upper surface of the positioning block 9 exerts a pushing force on the inclined surface of the limiting block 15, pushing the limiting block 15 away from the limiting block 10. During this process, the spring 12 is stretched, causing it to deform. When the limiting groove 16 and the limiting block 15 are at the same level, the spring 12 releases its elastic force, pushing the limiting block... 15 slides into the support groove 13. At this time, the limiting block 15 cooperates with the support groove 13 to restrict the positioning block 9, so that the positioning block 9 will not move downward relative to the limiting block 10. Then, the electric push rod 8 is activated to drive the positioning block 9 to move downward. The positioning block 9 gives the limiting block 10 a downward force, which drives the separator tank 1 to connect downward with the oil storage tank 2. This causes the sealing cover 6 to come into close contact with the upper end of the sliding tube 4. The operation is convenient and no tools are needed during the installation process. This facilitates the cleaning and maintenance of the separator tank 1 and the oil storage tank 2 in the dual separation structure of the oil-gas separator. It also makes the seal between the fixed tube 5 and the sliding tube 4 tighter, making the connection between the separator tank 1 and the oil storage tank 2 more convenient, thereby increasing the stability and practicality of the dual separation structure of the oil-gas separator.

[0068] As described above, when the separator tank 1 and the oil storage tank 2 are needed, the two support blocks 11 need to be pulled out, so that the two support blocks 11 drive the two limiting blocks 15 to slide out of the support groove 13. At this time, the electric push rod 8 can be activated to slide the positioning block 9 out of the positioning groove 14. Then, the separator tank 1 is moved upward, and the separator tank 1 and the oil storage tank 2 are disassembled. The disassembly is convenient and quick, thereby increasing the installation and disassembly efficiency of the dual separation structure of the oil-gas separator. This also facilitates the cleaning and maintenance of the separator tank 1 and the oil storage tank 2 in the dual separation structure of the oil-gas separator, thereby increasing the practicality of the dual separation structure of the oil-gas separator.
