Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0023] In the petroleum industry, in order to fully separate oil, gas and water, a three-phase separator is generally used. When the three-phase separator is used, the oil-gas mixture is introduced into the three-phase separator, and the gas and liquid are pre-separated first, and the gas is dried and discharged from the exhaust port, and then the oil and water in the liquid are separated and discharged through the oil outlet and water outlet;

[0024] The above is a brief introduction to the basic working principle of the three-phase separator. For details, please refer to the utility model patent with publication number CN204798904U, which will not be repeated here.

[0025] During the use of the three-phase separator, since the oil-gas mixture introduced into the three-phase separator contains more impurities, it is generally necessary to pre-filter the oil-gas mixture to remove large particles of impurities in the oil-gas mixture and prevent the large particles of impurities from settling in the three-phase mixer. Specifically:

[0026] like Figure 1-Figure 3 As shown, the present application provides a three-phase separator, which includes a base 1 and a tank body 2 fixedly mounted on the base 1, the tank body 2 is used to separate the oil-gas mixture into three phases of oil, gas and water, a liquid inlet pipe 21 is fixedly mounted on the tank body 2, the liquid inlet pipe 21 is used to feed materials into the tank body 2, one end of the liquid inlet pipe 21 is externally mounted with an inlet pipe 22, the inlet pipe 22 is used to transport the oil-gas mixture into the three-phase separator;

[0027] Meanwhile, a screen 211 is installed inside the liquid inlet pipe 21, and the screen 211 is used to screen the oil-gas mixture to remove large particles of impurities;

[0028] In order to keep the screen 211 clean, an anti-blocking mechanism is provided at the liquid inlet pipe 21. The anti-blocking mechanism is located at the upper end of the screen 211 and is used to remove large particles of impurities on the screen 211. Specifically:

[0029] like Figure 1-Figure 3 As shown, the anti-blocking mechanism includes a first sealing plate 3 mounted on the surface of the liquid inlet pipe 21, and a sealing opening 213 adapted to the first sealing plate 3 is opened on the outer wall of the liquid inlet pipe 21, and the first sealing plate 3 is engaged in the sealing opening 213;

[0030] A sealing gasket 31 is installed on the first sealing plate 3, and the sealing gasket 31 is used to seal the first sealing plate 3 and the sealing port 213. At the same time, a cylinder 32 is fixedly installed on the tank body 2, and the output end of the cylinder 32 is fixed to the first sealing plate 3, so that the first sealing plate 3 is suitable for moving with the output end of the cylinder 32;

[0031] A push rod 33 is fixedly mounted on the inner wall of the first sealing plate 3, and a second sealing plate 34 is fixedly mounted on one end of the push rod 33 away from the first sealing plate 3. At the same time, a discharge port 212 adapted to the second sealing plate 34 is opened on the outer wall of the liquid inlet pipe 21. The discharge port 212 is used to discharge foreign particles, and a sealing ring (not shown in the figure) is installed on the second sealing plate 34. The sealing ring is used to seal the second sealing plate 34 and the discharge port 212;

[0032] At the same time, a material receiving box 4 is mounted on the tank body 2, and the material receiving box 4 is used to collect impurities dropped from the discharge port 212. A fixing block 41 is fixedly mounted on the side of the material receiving box 4, and a bolt 411 is connected to the fixing block 41, and the bolt 411 is used to fix the material receiving box 4 to the tank body 2;

[0033] In the initial state, the first sealing plate 3 and the second sealing plate 34 are respectively located in the sealing port 213 and the discharge port 212, and seal the liquid inlet pipe 21;

[0034] When the oil-gas mixture is transported to the liquid inlet pipe 21 through the inlet pipe 22, the oil-gas mixture is initially filtered through the screen 211, and larger debris particles are blocked on the screen 211. The filtered oil-gas mixture enters the filtering mechanism in the tank body 2 for further filtering.

[0035] When a lot of debris is accumulated on the screen 211, the cylinder 32 is started. At this time, the output end of the cylinder 32 drives the first sealing plate 3 to move linearly, and the first sealing plate 3 pushes the push rod 33, and the push rod 33 drives the second sealing plate 34 to move, so that the discharge port 212 is in an open state. At the same time, the first sealing plate 3 pushes the impurity particles in the direction of the discharge port 212, and the discharged impurity particles fall into the inside of the receiving box 4. After cleaning, the cylinder 32 is started again to drive the first sealing plate 3 and the second sealing plate 34 to reset, thereby achieving efficient cleaning of the screen 211, and then simply removing impurities from the oil-gas mixture entering the filtering mechanism in the tank body 2, avoiding the problem of a large number of impurities in the oil-gas mixture entering the tank body 2 and accelerating the clogging of the filtering mechanism.

[0036] In order to solve the problem of centralized processing of the collected larger impurities, such as Figure 1-Figure 3 As shown, both sides of the bottom of the receiving box 4 are opened, and support plates 42 are fixedly installed on both sides of the tank body 2. A storage box 421 is placed on the support plate 42. The storage box 421 is used to collect larger impurities. The support plate 42 is used to support and place the storage box 421, and a placement groove (not marked in the figure) that is compatible with the bottom size of the storage box 421 is opened on the support plate 42.

[0037] When foreign particles fall into the receiving box 4, they fall into the storage box 421 through the bottom of the receiving box 4. When the storage box 421 is overfilled, the storage box 421 can be taken out of the placement slot to centrally process the collected foreign particles.

[0038] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
