Description

Technical Field

[0001] The utility model relates to the technical field of three-phase separators, in particular to an automatic sewage discharge device for a three-phase separator. Background Art

[0002] The three-phase separator is one of the most commonly used equipment in the development and production process of oil fields. It is a "solid, liquid, and gas" three-phase separation device installed under the pump in the oil and water wells of the oil field. During the use of the three-phase separator, the accumulation of sediment inside will reduce the volume inside the separator, and the sediment inside needs to be cleaned and removed. Therefore, an online sewage discharge equipment for the three-phase separator is needed.

[0003] After searching, a utility model patent with the publication number of CN220834450U specifically discloses an online sewage discharge device for a three-phase separator, including a three-phase separator body, a sewage discharge assembly is arranged below the three-phase separator body, an oil outlet assembly is arranged below the three-phase separator body, and the sewage discharge assembly includes a mounting sleeve. The online sewage discharge device for the three-phase separator is provided with a sewage discharge assembly, which is conducive to collecting and centrally treating the silt separated inside the three-phase separator during use. When the online sewage discharge device for the three-phase separator is used, the storage box is first installed with the mounting sleeve through a threaded joint. During use, the mixture is injected from the injection port, and the silt in the mixture passes through the filter screen and the leak plate through the three-phase separator and enters the storage box. At the same time, the vibration motor drives the connection frame to vibrate, and the connection frame shakes inside the slide rail through the movable block and the telescopic spring to prevent the silt from clogging.

[0004] In the above patent, the automatic drainage operation of the sediment inside the three-phase separator is realized only by the mutual cooperation between the filter screen, the leak plate and the vibration motor. However, in the above patent, since the height of the oil drain pipe is fixed, and during the use of the three-phase separator, the oil-water components transported to the inside of the three-phase separator each time have different oil-to-water ratios. Therefore, when the water content is high, the oil drain pipe will be completely immersed in water, thereby affecting the separation quality of the three-phase separator.

[0005] Therefore, it is necessary for us to propose an automatic sewage discharge device for a three-phase separator to solve the above problems. Utility Model Content

[0009] Preferably, the oil outlet mechanism includes an oil outlet pipe, which is connected and fixed to the bottom end of the separator tank body, and passes through the interior of the separator tank body and is located between the sewage discharge assembly and the fixed plate. The oil outlet pipe passes through the interior of the separator tank body and is slidably connected with floating plates on both sides, the top of the floating plate is connected and fixed with a support plate, and is slidably connected to the interior of the oil outlet pipe, the top of the support plate is connected and fixed with a sealing cover, and is located at the top of the oil outlet pipe, the bottom end of the floating plate is connected and fixed with a sealing ring, and is slidably connected to the interior of the oil outlet pipe, the bottom end of the sealing ring is connected and fixed with a limiting plate, the top of the limiting plate is connected and fixed with a small spring, and is sleeved with the outer wall of the sealing ring.

[0010] Preferably, a circulation groove is provided at the bottom end of the diverter plate, a mounting groove matching the water outlet pipe and sewage discharge assembly is provided at the bottom end of the separator tank body, and one end of the air outlet pipe passes through the separator tank body and is close to the top of the inner wall of the separator tank body.

The mixed water transported to the separator tank contacts and collides with the diverter plate, so that the gas inside the mixed water is released, so that the gas passes through the gas outlet pipe at the top of the separator tank. At the same time, the oil and water flow into the separator tank gradually and steadily through the annular flow groove at the bottom of the diverter plate, so that the oil and water are better separated by static standing.

[0015] 2. Through the static separation of oil and water inside the separator tank, the oil will float on the water surface due to its light density. At the same time, the floating plate contacts the water surface, and the floating plate will float on the water surface and sink in the oil layer. As the water surface continues to rise, it will push the floating plate to move, so that the floating plate drives the limit plate at the bottom of the sealing ring to squeeze the small spring to shrink and move, so that the limit plate drives the sealing ring to move, and the sealing ring gradually seals and isolates the sealing grooves at both ends of the oil outlet pipe, so that water will not flow into the inside of the oil outlet pipe through the sealing groove, while the oil layer flows into the inside of the oil outlet pipe through the sealing groove. At the same time, the movement of the floating plate drives the support plate at the top to move, and the movement of the support plate drives the sealing cover to move, so as to release the sealing operation on the top of the oil outlet pipe, so that the oil layer can be discharged faster through the oil outlet pipe. At the same time, according to the different water content in the oil-gas-water mixture, the distance that the water surface drives the floating plate to float is also different, so that the oil layer can always be discharged from the inside of the separator tank through the oil outlet pipe, that is, the oil outlet pipe can adjust the height of the oil outlet slot in real time according to the different oil-water components inside the separator tank, thereby reducing the possibility of water flowing into the inside of the oil outlet pipe.

[0030] How this utility works:

[0031] Refer to the instruction manual Figure 1-4 , through the water inlet pipe 201, the oil-gas-water mixture is transported to the separator tank body 1 through the water inlet pipe 201, and the mixed water transported to the separator tank body 1 contacts and collides with the diverter plate 202, so that the gas inside the mixed water is released, so that it is convenient for the gas to pass through the gas outlet pipe 203 at the top of the separator tank body 1, and at the same time, the oil and water flow into the separator tank body 1 gradually and steadily through the annular flow groove at the bottom of the diverter plate 202, so that the oil and water are better statically separated, and at the same time, the precipitated water is discharged through the water outlet pipe 204 controlled by the solenoid valve 206, and at the same time, the sewage discharge component 205 cleans the mud and dirt precipitated inside the separator tank body 1, so that the separator tank body 1 can complete the separation operation of the oil-gas-water mixture;

[0032] Refer to the instruction manual Figure 1-4 , through the static separation of oil and water inside the separator tank 1, the oil will float on the water surface due to its light density, and at the same time, the floating plate 302 will contact the water surface, and the floating plate 302 will float on the water surface and sink in the oil layer. As the water surface continues to rise, it will push the floating plate 302 to move, so that the floating plate 302 drives the limiting plate 306 at the bottom of the sealing ring 305 to squeeze the tiny spring 307 to shrink and move, so that the limiting plate 306 drives the sealing ring 305 to move, so that the sealing ring 305 gradually seals and isolates the sealing grooves at both ends of the oil outlet pipe 301, so that water will not flow into the inside of the oil outlet pipe 301 through the sealing groove, while the oil layer will flow into the outlet through the sealing groove. Inside the oil pipe 301, the floating plate 302 moves and drives the support plate 303 at the top to move. The support plate 303 moves and drives the sealing cover 304 to move, thereby releasing the sealing operation on the top of the oil outlet pipe 301, so that the oil layer can be discharged faster through the oil outlet pipe 301. At the same time, according to the different water content in the oil-gas-water mixture, the floating distance driven by the water surface is also different, so that the oil layer can always be discharged from the separator tank body 1 through the oil outlet pipe 301. That is, the oil outlet pipe 301 can adjust the height of the oil outlet slot in real time according to the different oil-water components inside the separator tank body 1, thereby reducing the possibility of water flowing into the oil outlet pipe 301.

[0033] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
