A sedimentation tank for oil extraction process

Abstract

This utility model discloses a sand setter for oil extraction processes, relating to the field of oil extraction technology. It includes a support frame, a sand settling box fixedly mounted at the top of the support frame, a controller fixedly mounted on one side of the front end of the sand settling box, and an oil inlet pipe fixedly mounted on the upper left end of the sand settling box. In this utility model, oil enters the sand settling box through the oil inlet pipe. A rotating rod drives agitator blades to rotate, facilitating the sedimentation of sand particles in the oil. A rotating transmission rod drives a cam to rotate, allowing the cam's protrusion to contact the lower end of a filter screen and push the screen upwards. This stretches the springs on both sides of the filter screen. After the cam protrusion separates from the filter screen, the springs cause the filter screen to vibrate up and down, accelerating the separation of oil and sand particles and preventing sand particles from clogging the filter screen and affecting the efficiency of oil sand settling. The sand particles settle below the filter screen and can smoothly sink to the bottom of the sand settling box, then fall into the sand collection box through the bottom chamber.

Description

Technical Field

[0001] This utility model relates to the field of oil extraction technology, specifically to a settling device for oil extraction processes. Background Technology

[0002] Petroleum is a fluid mineral buried deep underground. Initially, people called naturally occurring oily liquid minerals petroleum, combustible gases natural gas, and solid combustible fuel minerals bitumen. As research into these minerals deepened, it was recognized that they are all hydrocarbon compounds in composition and interconnected in their formation, so they are collectively referred to as petroleum.

[0003] As oilfield development progresses, more and more wells produce sand. When sand production is severe, it can easily clog the nozzles or cause them to break. Therefore, a sand remover is needed in the oil extraction process to remove sand.

[0004] However, when using existing sand setters, the oil flow rate is fast during sand settling, while the sand settling is slow, resulting in poor sand removal effect and easy clogging of the filter screen, which seriously affects the efficiency of oil sand settling. Utility Model Content

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A sand setter for oil extraction includes a support frame, a sand settling box fixedly mounted at the top of the support frame, a controller fixedly mounted on one side of the front end of the sand settling box, an oil inlet pipe fixedly mounted on the upper left end of the sand settling box, a bottom box fixedly mounted on the bottom of the sand settling box, a sand collection box movably mounted at the bottom of the bottom box, a screening mechanism inside the sand settling box, sand discharge mechanisms on both sides of the sand collection box, and an oil discharge pipe fixedly mounted on the lower right end of the sand settling box.

[0007] The screening mechanism includes a horizontal plate, one end of which is symmetrically and fixedly connected to the inner walls of both sides of the settling tank. Multiple sets of springs are fixedly installed at the upper end of the horizontal plate, and a filter screen is fixedly installed at the top of the springs. A transmission rod is rotatably installed below the filter screen, and a cam is fixedly installed at the top of the transmission rod. A motor is fixedly installed at the rear end of the settling tank.

[0008] Preferably, the output end of the second motor is connected to the bottom end of the transmission rod, and the protrusion of the cam is in contact with the lower end of the filter screen.

[0009] Preferably, the filter screen can separate oil sand.

[0010] Preferably, the sand discharge mechanism includes a fixed plate, the lower end of which is symmetrically fixedly connected to both sides of the upper end of the sand collection box. A threaded sleeve is fixedly provided in the middle of the fixed plate, and a screw rod is installed in the internal thread of the threaded sleeve. A knob is fixedly provided at the top of the screw rod, and a retaining plate is rotatably installed at the bottom of the screw rod. A retaining groove is provided on both sides of the lower end of the bottom box. Electric push rods are symmetrically fixedly provided on both sides of the rear end of the bottom box. An ear plate is fixedly provided at the top of the output rod of the electric push rod. A sliding groove is provided through the inner wall of the rear end of the bottom box, and a sealing plate is slidably provided inside the sliding groove.

[0011] Preferably, the card plate and the card slot are fitted together and are movably installed, which facilitates the disassembly and assembly of the sand collection box.

[0012] Preferably, one end of the ear plate is symmetrically and fixedly connected to both sides of the rear end of the sealing plate, and the sealing plate is fitted into the interior of the bottom box and is movably installed.

[0013] Preferably, the bottom box is funnel-shaped.

[0014] Preferably, a motor is fixedly installed at the top of the sedimentation tank, a rotating rod is driven to the output end of the motor, and multiple sets of stirring blades are fixedly installed on the lower end of the rotating rod.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This utility model provides a sand settling device for oil extraction processes. Through a screening mechanism, oil enters the sand settling box via an inlet pipe. A rotating rod drives the stirring blades to rotate, facilitating the sedimentation of sand particles in the oil. A rotating transmission rod drives a cam to rotate, allowing the cam's protrusion to contact the lower end of the filter screen and push the screen upwards. This stretches the springs on both sides of the filter screen. After the cam protrusion separates from the filter screen, the springs cause the filter screen to vibrate up and down, accelerating the separation of oil and sand particles and preventing sand particles from clogging the filter screen and affecting the efficiency of oil sand settling. The sand particles settle below the filter screen and can smoothly sink to the bottom of the sand settling box, then fall into the sand collection box through the bottom chamber.

[0017] This utility model provides a sand settling device for oil extraction processes. Through a sand discharge mechanism, sand particles settle into a sand collection box. A knob can then be rotated, causing a screw to rotate within a screw sleeve. This screw moves a clamping plate to both sides, separating the clamping plate from the clamping groove, thus facilitating the removal of the sand collection box. Simultaneously, an electric push rod can be activated. The output rod of the electric push rod retracts, causing the ear plate and sealing plate to move forward synchronously. This allows the sealing plate to seal the bottom of the bottom box, facilitating the rapid removal of the collected sand particles. After the bottom box is sealed, it prevents large-scale oil leakage, benefiting the user. Attached Figure Description

[0024] The present invention will be further described in detail below with reference to embodiments:

[0025] like Figures 1-5 As shown, this utility model provides a sand setter for oil extraction processes, including a support 1, a sand settling box 2 fixedly mounted at the top of the support 1, a controller 3 fixedly mounted on one side of the front end of the sand settling box 2, an oil inlet pipe 4 fixedly mounted on the upper left end of the sand settling box 2, a bottom box 5 fixedly mounted on the bottom of the sand settling box 2, a sand collection box 6 movably mounted on the bottom of the bottom box 5, a screening mechanism 7 inside the sand settling box 2, sand discharge mechanisms 8 on both sides of the sand collection box 6, and an oil discharge pipe 9 fixedly mounted on the lower right end of the sand settling box 2.

[0026] The bottom box 5 is arranged in a funnel shape.

[0027] A motor 10 is fixedly installed at the top of the sedimentation tank 2. A rotating rod 11 is driven and installed at the output end of the motor 10. Multiple sets of stirring blades 12 are fixedly installed on the lower end of the rotating rod 11.

[0028] In this scheme, the bottom box 5 is funnel-shaped, which allows the precipitated sand particles to fall quickly into the sand collection box 6. The rotating rod 11 and stirring blades 12 facilitate the sedimentation of sand particles in the petroleum.

[0029] like Figure 3 As shown, the screening mechanism 7 includes a horizontal plate 71. One end of the horizontal plate 71 is symmetrically fixedly connected to the inner walls of both sides of the settling tank 2. Multiple sets of springs 72 are fixedly installed at the upper end of the horizontal plate 71. A filter screen 73 is fixedly installed at the top of the springs 72. A transmission rod 74 is rotatably installed below the filter screen 73. A cam 75 is fixedly installed at the top of the transmission rod 74. A motor 76 is fixedly installed at the rear end of the settling tank 2.

[0030] The output end of motor 76 is connected to the bottom end of transmission rod 74, and the protrusion of cam 75 is in contact with the lower end of filter screen 73.

[0031] Filter 73 can separate oil sand.

[0032] In this design, under the repeated action of spring 72 and cam 75, filter screen 73 vibrates up and down at high frequency and small amplitude. The kinetic energy generated by this mechanical vibration effectively breaks the adhesion between sand particles and filter screen 73 caused by adsorption, causing the sand particles attached to the surface of filter screen 73 to fall off quickly, making it easier for them to settle.

[0033] like Figures 4-5 As shown, the sand discharge mechanism 8 includes a fixed plate 81. The lower end of the fixed plate 81 is symmetrically fixed to both sides of the upper end of the sand collection box 6. A screw sleeve 82 is fixedly provided in the middle of the fixed plate 81. A screw rod 83 is installed in the internal thread of the screw sleeve 82. A knob 84 is fixedly provided at the top of the screw rod 83. A retaining plate 85 is rotatably installed at the bottom end of the screw rod 83. A retaining groove 86 is provided on both sides of the lower end of the bottom box 5. Electric push rods 87 are symmetrically fixed on both sides of the rear end of the bottom box 5. An ear plate 88 is fixedly provided at the top of the output rod of the electric push rod 87. A sliding groove 89 is provided through the inner wall of the rear end of the bottom box 5. A sealing plate 810 is slidably provided inside the sliding groove 89.

[0034] The card plate 85 is fitted into the card slot 86 and is movable, which makes it easy to disassemble and assemble the sand collection box 6.

[0035] One end of the ear plate 88 is symmetrically and fixedly connected to both sides of the rear end of the sealing plate 810. The sealing plate 810 is fitted into the interior of the bottom box 5 and can be installed movably.

[0036] In this design, the card plate 85 and the card slot 86 are fitted together, which facilitates the installation of the sand collection box 6. At the same time, the sealing plate 810 moves backward, which allows the interior of the bottom box 5 to be opened, facilitating the sedimentation of sand particles.

[0037] The working principle of the sand setter used in this oil extraction process will be explained in detail below.

[0038] like Figures 1-5As shown, in this oil extraction process, the sand setter allows oil to enter the sand settling tank 2 through the inlet pipe 4. Then, motor 10 is started, which drives the stirring blades 12 to rotate via the rotating rod 11, facilitating the sedimentation of sand particles in the oil. Motor 2 76 drives the cam 75 to rotate via the transmission rod 74. The protrusion of the rotating cam 75 contacts the lower end of the filter screen 73, pushing the screen upwards. This stretches the springs 72 on both sides of the filter screen 73. After the protrusion of the cam 75 separates from the filter screen 73, the springs 72 cause the filter screen 73 to vibrate up and down, accelerating the separation of oil and sand particles and preventing sand particles from clogging the filter screen 73, thus affecting the efficiency of oil sand settling. This allows the sand particles to settle below the filter screen 73, passing through the screen... The process continues, and the sand particles that have successfully separated from the oil sink directly to the bottom of the sedimentation tank 2. The bottom box 5 is funnel-shaped, which facilitates the sand particles to slide into the sand collection box 6 below. When it is necessary to remove the sand particles from the sand collection box 6, the knob 84 can be turned, which drives the screw 83 to rotate in the screw sleeve 82. The screw 83 drives the clamping plate 85 to move to both sides, so that the clamping plate 85 separates from the clamping groove 86, making it easier to remove the sand collection box 6. At the same time, the electric push rod 87 can be activated. The output rod of the electric push rod 87 can be retracted, which can drive the ear plate 88 and the sealing plate to move forward synchronously. This allows the sealing plate 810 to seal the bottom of the bottom box 5, making it easier to disassemble the sand collection box 6 and preventing a large amount of oil leakage, thus facilitating its use.

[0039] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
