Description

Technical Field

[0001] The present invention relates to the technical field of petroleum, and specifically to an anti-gas-blocking device for petroleum pipelines. Background Art

[0002] Petroleum is a fluid mineral buried deep underground. Initially, people called the oily liquid minerals produced in nature petroleum, the combustible gas natural gas, and the solid combustible oily minerals asphalt. With the in-depth study of these minerals, it was recognized that they all belong to hydrocarbon compounds in composition and are interrelated in origin, so they are collectively called petroleum. At the 11th World Petroleum Congress in September 1983, it was proposed that petroleum is a complex mixture composed of gaseous, liquid, and solid hydrocarbon compounds existing in nature and a small amount of impurities. Therefore, petroleum extraction also includes natural gas extraction.

[0003] Petroleum extraction refers to the act of excavating and extracting petroleum in places where petroleum is stored. During the process of petroleum extraction, the driving mode of oil and gas flowing from the reservoir into the bottom of the well and then rising from the bottom of the well to the wellhead.

[0004] For example, an anti-gas-blocking device for a petroleum pipeline with the Chinese invention publication number: CN110878874A, includes a pipeline, a moving plate assembly, and an air extraction assembly; the pipeline includes a pipeline main body and a slot, and the slot is provided on the side wall of the pipeline main body; the moving plate assembly is used to close the slot, the moving plate assembly is slidably connected to the pipeline main body, and the sliding direction of the moving plate assembly relative to the pipeline main body is parallel to the axial direction of the pipeline; the air extraction assembly is installed on the moving plate assembly, and the air extraction assembly communicates the inside and outside of the pipeline main body for extracting the gas inside the pipeline main body. The present invention provides an anti-gas-blocking device for a petroleum pipeline, which can discharge the gas in the upper part of the oil pipeline and prevent the gas blockage of the petroleum pipeline.

[0005] The petroleum pipeline is composed of many groups of oil pipelines. When the circulating pump in the oil pipeline pressurizes, the petroleum in the pipeline circulates under pressure without bubbles: if the circulating petroleum is lost due to some reason, a large amount of gas will exist in the upper part of the oil pipeline. Since the density of air is smaller than that of petroleum, the petroleum at the high-pressure end cannot press down the air and is blocked, resulting in the inability of the petroleum in this oil pipeline to be circulated and transported.

[0006] The traditional gas-blocking position of the petroleum transmission pipeline needs to be manually dredged, which consumes a large amount of labor costs, and even causes the long-term shutdown of the petroleum transportation work. Moreover, the sand and gravel impurities doped in the petroleum will block the pipeline, and the workers cannot distinguish whether it is a gas block or a sand and gravel blockage, which is inconvenient for the workers to dredge. Summary of the Invention

[0007] (I) Technical Problems to be Solved

[0008] In view of the deficiencies of the prior art, the present invention provides an anti-air-blocking device for oil pipelines, which solves the problems that the blocked gas positions in traditional oil transmission pipelines need to be manually dredged, consuming a large amount of labor costs, and even causing long-term shutdowns of oil transportation work. In addition, the sand and gravel impurities mixed in the oil will block the pipeline, and workers cannot distinguish between air blockage and sand and gravel blockage, which is inconvenient for workers to dredge.

[0009] (II) Technical Solution

[0010] To achieve the above objectives, the present invention is realized through the following technical solutions: an anti-air-blocking device for oil pipelines, including a feed installation pipe, the output end of the feed installation pipe is fixedly connected and communicated with an internal oil treatment pipe, and the top of the internal oil treatment pipe is fixedly connected and communicated with an exhaust pipe component.

[0011] At the top end inside the internal oil treatment pipe, a walking track is fixedly connected. At the bottom end inside the walking track, a sealing slider is slidably connected. The bottom end of the exhaust pipe component is communicated with the inside of the walking track. The left side of the sealing slider is fixedly connected to the left side of the walking track through an elastic baffle. The bottom end of the sealing slider is fixedly connected to a blocking support plate. On the front surface of the blocking support plate, a guiding fan blade is fixedly connected. At the top end on the right side of the blocking support plate, a pressure activity mechanism is fixedly connected. Inside the guiding fan blade, a material blocking hole component is evenly arranged. The bottom end of the exhaust pipe component is communicated with the inside of the internal oil treatment pipe, discharging air outward, achieving the ability of automatic air exhaust, reducing the dredging work of workers, and improving the oil transmission efficiency. Part of the oil is transmitted upward, and another part of the oil passes through the material blocking hole component to filter the oil, avoiding the excessive concentration of sand and gravel in the pipeline and causing blockage.

[0012] Preferably, the pressure activity mechanism includes a contact pressing plate, the top end of the contact pressing plate is rotatably connected to the blocking support plate, and a mounting sleeve rod is evenly fixedly connected to the left side of the contact pressing plate.

[0013] Preferably, the pressure activity mechanism further includes a guiding cover groove and a driving tooth rod. The guiding cover groove is fixedly connected to the right side of the contact pressing plate, and the driving tooth rod is threadedly connected to the mounting sleeve rod.

[0014] Preferably, a material picking cone head is fixedly connected to the left side of the driving tooth rod. Inside the material picking cone head near the right side, a magnetic force storage groove is arranged. Inside the magnetic force storage groove, a swinging rotating block is rotatably connected. The material picking cone head gradually contacts the material blocking hole component, dredging and cleaning the impurities inside the material blocking hole component, realizing mechanical dredging through the change of pressure, and improving the continuous cyclic working ability of the device. The centrifugal force causes the swinging rotating block to swing outward, increasing the power in other directions for the sand and gravel, quickly separating the sand and gravel, and achieving the purpose of improving the cleaning efficiency.

[0015] Preferably, the material blocking hole member includes a pressure relief and material guiding hole, the pressure relief and material guiding holes are uniformly arranged inside the guiding fan blades, and transverse guiding grooves are uniformly arranged on the surface of the inner wall of the pressure relief and material guiding holes.

[0016] Preferably, the material blocking hole member further includes a movable cone block, and the outer surface of the movable cone block is slidably connected with the inside of the transverse guiding groove in a matching manner. When the structure of the pressure-actuated mechanism dredges the material blocking hole member, the movable cone block can be pushed forward to the front, ensuring that the removed sand and gravel can quickly break away, and avoiding blockage caused by long-term accumulation of sand and gravel.

[0017] Preferably, filtering sieve grooves are uniformly arranged inside the movable cone block, and positioning inclined plates are fixedly connected to the upper and lower ends on the right side of the filtering sieve grooves.

[0018] Preferably, the exhaust pipe member includes an exhaust passage, the bottom end of the exhaust passage is communicated with the inside of the traveling track, the top end of the exhaust passage is fixedly communicated with a pressing cone groove, and pressing cover plates are uniformly fixedly connected to the surface of the inner wall of the exhaust passage. The flowing petroleum can gradually unfold the pressing cover plates, and the unfolded pressing cover plates block the exhaust passage, reducing the flowing area of the petroleum and increasing the resistance of petroleum transmission, so as to avoid the purpose of petroleum leakage and waste.

[0019] (III) Beneficial effects

[0020] The present invention provides an anti-air-blocking device for an oil pipeline. It has the following beneficial effects:

[0021] (1) For the anti-air-blocking device of the oil pipeline, the petroleum transmitted under high pressure is conducted into the inner pipe of petroleum treatment and presses against the blocking support plate. Thus, the flowing petroleum gradually pushes the blocking support plate to the right. At this time, the sealing slider drives the elastic baffle to unfold. At this time, the unfolded elastic baffle blocks the bottom of the exhaust pipe member, preventing petroleum from discharging outward from the exhaust pipe member and ensuring the normal transmission work of petroleum. When an air-blocking phenomenon occurs, the petroleum no longer flows and pushes the blocking support plate. Under the action of the elastic baffle, the sealing slider returns and moves to the leftmost side of the traveling track, connecting the bottom end of the exhaust pipe member with the inside of the inner pipe of petroleum treatment, discharging the air outward, realizing the automatic air exhaust ability, reducing the dredging work of workers, and achieving the purpose of improving the petroleum transmission efficiency.

[0022] (2) For the anti-air-blocking device of the oil pipeline, during the petroleum transmission process, the guiding fan blades guide the petroleum upward. Part of the petroleum is transmitted upward, and the other part of the petroleum passes through the material blocking hole member to filter the petroleum, avoiding blockage caused by excessive concentration of sand and gravel in the pipeline.

[0023] (3). The gas blockage prevention device for the oil pipeline. The movable cone block adopts a conical structure, and the filter sieve groove absorbs large particles of sand and gravel to ensure that the passing oil can be fully filtered. When the structure of the pressure activity mechanism dredges the material blocking hole part, the movable cone block can be pushed forward to the front, ensuring that the removed sand and gravel can quickly break away, avoiding blockage caused by long-term accumulation of sand and gravel.

[0024] (4). The gas blockage prevention device for the oil pipeline. When the material blocking hole part is blocked, at this time, the oil only flows from above the blocking support plate, so the pressure for the pressure activity mechanism to turn downward increases, and thus the pressure activity mechanism is turned downward, and the material removal cone head gradually contacts the material blocking hole part, dredging and cleaning the impurities inside the material blocking hole part. Mechanical dredging is achieved through the change of pressure, improving the continuous cyclic working ability of the equipment.

[0025] (5). The gas blockage prevention device for the oil pipeline. When the material removal cone head is inserted into the material blocking hole part, when the resistance of sand and gravel blockage is large, the contact extrusion force will drive the toothed rod to rotate inside the installation sleeve rod, and thus the centrifugal force will swing the swing block outward, increasing the driving force in other directions for the sand and gravel, quickly separating the sand and gravel, and achieving the purpose of improving the cleaning efficiency.

[0026] (6). The gas blockage prevention device for the oil pipeline. The air in the pipeline is discharged outward from the exhaust passage, and the extrusion cover plate has little influence on the discharged air. When viscous oil is discharged outward from the exhaust passage, due to the large viscous force of the oil and the bottom tension of the extrusion cover plate, the flowing oil can gradually unfold the extrusion cover plate, and the unfolded extrusion cover plate blocks the exhaust passage, reducing the oil flow area, increasing the oil transmission resistance, and avoiding the waste of oil leakage.

Detailed implementation manners

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] As Figures 1-6 shown, the present invention provides a technical solution: an anti-air blockage device for an oil pipeline, including a feed installation pipe 1. The output end of the feed installation pipe 1 is fixedly communicated with an inner pipe 2 for oil treatment. The top of the inner pipe 2 for oil treatment is fixedly communicated with an exhaust pipe fitting 3.

[0036] At the top end inside the inner pipe 2 for oil treatment, a walking track 4 is fixedly connected. At the bottom end inside the walking track 4, a sealing slider 5 is slidably connected. The bottom end of the exhaust pipe fitting 3 is communicated with the inside of the walking track 4. The left side of the sealing slider 5 is fixedly connected with the left side of the walking track 4 through an elastic baffle 6. The bottom end of the sealing slider 5 is fixedly connected with a blocking support plate 7. On the front surface of the blocking support plate 7, a guiding fan blade 8 is fixedly connected. At the top end on the right side of the blocking support plate 7, a pressure activity mechanism 9 is fixedly connected. Inside the guiding fan blade 8, a material blocking hole part 10 is evenly arranged. The bottom end of the exhaust pipe fitting 3 is communicated with the inside of the inner pipe 2 for oil treatment, discharging air outwards, achieving the ability of automatic exhaust, reducing the dredging work of workers, and improving the purpose of oil transmission efficiency. Part of the oil is transmitted upwards, and the other part of the oil passes through the material blocking hole part 10 to filter the oil, avoiding excessive concentration of sand and gravel in the pipeline and causing blockage.

[0037] The pressure activity mechanism 9 includes a contact pressing plate 91. The top end of the contact pressing plate 91 is rotatably connected with the blocking support plate 7. On the left side of the contact pressing plate 91, installation sleeve rods 92 are evenly fixedly connected.

[0038] The pressure activity mechanism 9 further includes a guiding cover groove 93 and a driving rack 94. The guiding cover groove 93 is fixedly connected to the right side of the contact pressing plate 91. The driving rack 94 is threadedly connected with the installation sleeve rod 92.

[0039] A material removal cone head 95 is fixedly connected to the left side of the drive rack 94. Inside the material removal cone head 95 near the right side, there is a magnetic storage groove 96. Inside the magnetic storage groove 96, a swinging rotating block 97 is rotatably connected. The material removal cone head 95 gradually contacts the material blocking hole part 10, dredges and cleans the impurities inside the material blocking hole part 10, realizes mechanical dredging through the change of pressure, and improves the continuous circulation working ability of the equipment. The centrifugal force swings the swinging rotating block 97 to extend outwards, increases the power in other directions of the sand and gravel, quickly separates the sand and gravel, and achieves the purpose of improving the cleaning efficiency.

[0040] The material blocking hole part 10 includes a pressure relief and material guiding hole 101. The pressure relief and material guiding holes 101 are evenly arranged inside the guiding fan blades 8. Transverse guiding grooves 102 are evenly arranged on the surface of the inner wall of the pressure relief and material guiding hole 101.

[0041] The material blocking hole part 10 further includes a movable cone block 103. The outer surface of the movable cone block 103 is slidably connected with the inside of the transverse guiding groove 102 in a matching manner. When the structure of the pressure activity mechanism 9 dredges the material blocking hole part 10, the movable cone block 103 can be pushed towards the front, ensuring that the removed sand and gravel can quickly separate, and avoiding blockage caused by long-term accumulation of sand and gravel.

[0042] Filtering sieve grooves 104 are evenly arranged inside the movable cone block 103. Positioning inclined plates 105 are fixedly connected to the upper and lower ends on the right side of the filtering sieve grooves 104.

[0043] The exhaust pipe part 3 includes an exhaust passage 31. The bottom end of the exhaust passage 31 is communicated with the inside of the traveling track 4. The top end of the exhaust passage 31 is fixedly communicated with an extrusion cone groove 32. Extrusion cover plates 33 are evenly fixedly connected to the surface of the inner wall of the exhaust passage 31. The flowing petroleum can gradually unfold the extrusion cover plates 33. The unfolded extrusion cover plates 33 block the exhaust passage 31, reduce the flowing area of the petroleum, increase the transmission resistance of the petroleum, and avoid the waste of petroleum leakage.

[0044] Working principle: The feeding installation pipe 1 and the internal oil treatment pipe 2 are installed and connected at the middle position of the oil transmission pipeline. Oil enters the inside of the internal oil treatment pipe 2 from the feeding installation pipe 1. The oil transmitted under high pressure is conducted into the inside of the internal oil treatment pipe 2 and squeezes and blocks the support plate 7. Thus, the flowing oil gradually pushes the support plate 7 to the right. At this time, the sealing slider 5 drives the elastic baffle 6 to unfold. At this time, the unfolded elastic baffle 6 blocks the bottom of the exhaust pipe part 3, preventing oil from discharging outward from the exhaust pipe part 3 and ensuring the normal oil transmission work. When an air blockage occurs, the oil no longer flows to push the support plate 7. Under the action of the elastic baffle 6, the sealing slider 5 returns and moves to the leftmost side of the running track 4, connecting the bottom end of the exhaust pipe part 3 with the inside of the internal oil treatment pipe 2 and discharging the air outward, achieving the ability of automatic exhaust, reducing the dredging work of workers, and improving the oil transmission efficiency; during the oil transmission process, the guiding fan blades 8 guide the oil upward. Part of the oil is transmitted upward, and the other part of the oil passes through the material blocking hole part 10 to filter the oil and prevent excessive concentration of sand and gravel in the pipeline from causing blockage; the movable cone block 103 adopts a conical structure, and the filter sieve groove 104 absorbs large-particle sand and gravel, ensuring that the passing oil can be fully filtered. When the pressure activity mechanism 9 dredges the material blocking hole part 10, the movable cone block 103 can be pushed forward to the front, ensuring that the removed sand and gravel can quickly break away and preventing blockage caused by long-term accumulation of sand and gravel; when the material blocking hole part 10 is blocked, at this time, the oil only flows from above the support plate 7. Thus, the pressure for the pressure activity mechanism 9 to turn downward increases, and the pressure activity mechanism 9 turns downward. Thus, the material removal cone head 95 gradually contacts the material blocking hole part 10 to dredge and clean the impurities inside the material blocking hole part 10, realizing mechanical dredging through the change of pressure and improving the continuous circulation working ability of the equipment; when the material removal cone head 95 is inserted into the material blocking hole part 10, when the resistance of sand and gravel blockage is large, the contact extrusion force will drive the rack 94 to rotate inside the installation sleeve rod 92. Thus, the centrifugal force will swing the swing block 97 outward to increase the power in other directions for the sand and gravel, quickly separating the sand and gravel and achieving the purpose of improving the cleaning efficiency; the air in the pipeline is discharged outward from the exhaust channel 31. The extrusion cover plate 33 has little influence on the discharged air. When viscous oil is discharged outward from the exhaust channel 31, due to the large viscosity of the oil and the bottom tension of the extrusion cover plate 33, the flowing oil can gradually unfold the extrusion cover plate 33. The unfolded extrusion cover plate 33 blocks the exhaust channel 31, reducing the oil flow area and increasing the oil transmission resistance to prevent oil leakage and waste.
