Description

Technical Field

[0001] The invention relates to the field of petroleum extraction, in particular to a petroleum extraction device for residual oil. Background Art

[0002] In the process of oil extraction, most of the oil is extracted from the ground in the form of liquid. However, since there are many impurities in the oil, the extracted oil generally needs to be left to stand so that the impurities in the oil can be separated from the liquid oil. However, since the oil has strong viscosity, in the process of standing to separate the oil and impurities, some of the oil will still exist in the separated residue. Generally, a crusher and an extruder are used to extract the oil from the residue. First, the oil residue is crushed by a crusher, and then the oil in the oil residue is separated by an extruder. However, some of the oil residue is tightly combined with the oil and is difficult to separate, and some of it is loosely combined with the oil and is easier to separate. If the oil residues that are difficult to separate and those that are easy to separate are crushed and squeezed indiscriminately, although some oil can be obtained, there must be a lot of oil waste in the relatively difficult to separate oil residues.

[0003] Therefore, we designed a petroleum extraction device for residual oil that can adjust the oil residue filtering rate. Summary of the invention

[0008] Furthermore, it also includes a blocking component for changing the discharge state of the oil residue, the blocking component is arranged on the filtering outer barrel, the blocking component includes an evenly distributed fixed frame, the evenly distributed fixed frame is fixedly connected to the filtering outer barrel, a card block is slidably connected in the fixed frame, a third spring is connected between the card block and the adjacent fixed frame, the fixed frame is slidably connected with a symmetrically distributed baffle, a fourth spring is connected between the baffle and the adjacent fixed frame, a card frame is slidably connected to the fixed frame, and an evenly distributed protective cover is fixed in the sedimentation box, and a fixed frame is slidably connected in the protective cover.

[0009] Furthermore, a side of the clamping block close to the baffle is an inclined surface, and the clamping block is extrusion-fitted with the baffle.

[0010] Furthermore, the card block is provided with symmetrically distributed protrusions on one side close to the card frame, and the card frame is provided with an inclined surface on the upper side of the special-shaped protrusions, and the protrusions on the card block are pressed and matched with the inclined surface on the card frame.

[0011] Furthermore, a V-shaped groove is provided on a side of the clamping frame close to the fixing frame, the V-shaped groove of the clamping frame is extrusion-fitted with the fixing frame, and a side of the fixing frame close to the sliding frame is an arc surface.

[0012] Furthermore, it also includes a discharge component for adjusting the discharge volume, the discharge component is arranged on the filter outer barrel, the discharge component includes a pressure sensor, the pressure sensor is installed on the side of the filter outer barrel close to the discharge port, and a second electric push rod is installed on the side of the filter outer barrel close to the pressure sensor.

[0013] Furthermore, an anti-blocking component is included to prevent the filter frame from being blocked. The anti-blocking component is arranged in the sedimentation box. The anti-blocking component includes an eccentric wheel, and the eccentric wheel is connected to the output shaft of the motor. The side of the eccentric wheel close to the filter frame is rotatably connected to a pull rod, and the pull rod is rotatably connected to a push rack, and the push rack is slidably connected to the filter frame.

[0014] Furthermore, it also includes a cleaning component to prevent material residue from affecting the judgment of the pressure sensor. The cleaning component is arranged on the force-bearing plate. The cleaning component includes a friction plate. The friction plate is arranged on the push frame. A rotating frame is rotatably connected to the force-bearing plate. The rotating frame passes through the force-bearing plate and cooperates with the friction plate.

[0015] Compared with the prior art, the present invention has the following advantages: the present invention uses the gravity of the oil dripping onto the stress plate to cause the second spring to squeeze the pressure sensor. Since the oil will slowly flow out from the outside of the stress plate, when the speed of the oil dripping is much greater than the speed of the oil flowing out from the outside of the stress plate, the oil on the stress plate will increase, causing the pressure sensor to control the telescopic end of the first electric push rod to shorten through the control module, thereby causing the slide to move downward, causing the discharge port of the filter outer barrel to become larger, thereby accelerating the speed at which the oil residue flows out of the discharge port of the filter outer barrel and improving the efficiency of filtering the oil residue; when the speed of the oil dripping is less than the speed at which the oil flows out from the outside of the stress plate, the oil on the stress plate decreases, causing the pressure sensor to control the telescopic end of the first electric push rod to extend through the control module, thereby driving the slide to move upward, causing the discharge port of the filter outer barrel to become smaller, thereby slowing down the speed at which the oil residue flows out of the discharge port of the filter outer barrel and improving the quality of filtering the oil residue.

[0016] The oil residue is moved slightly by rotating the filter inner barrel, which facilitates the separation of oil from the oil residue. Since a liquid guide plate is provided in the filter inner barrel, the liquid guide plate contacts the inner wall of the rotating filter inner barrel, so the oil that has penetrated into the filter inner barrel but has not yet gathered can be scraped and gathered together, and then dripped through the liquid guide plate on the lower side of the liquid guide plate, thereby promoting the oil dripping process and increasing the speed of separation of the oil residue and the oil.

[0017] The slide frame clamps the fixed frame and then the clamping block, so that the clamping block blocks the falling oil residue, thereby changing the falling path of the oil residue, and then changing the state of the oil residue discharge, so that the oil residue is separated from the oil faster.

[0018] When too much oil residue accumulates on the lower side of the filter outer barrel, the pressure sensed by the pressure sensor reaches a preset value, and the control module will control the telescopic end of the second electric push rod to contract, causing the retaining ring to move upward, thereby expanding the discharge port of the filter outer barrel, allowing the accumulated oil residue to be quickly discharged, thereby improving the oil filtration efficiency.

[0019] When the output shaft of the motor rotates, it drives the pull rod to swing, causing the pull rod to pull the push frame to move back and forth, pushing the fine oil residue on the filter plate to the collection frames on both sides, thereby preventing the fine oil residue from clogging the filter frame and affecting the oil separation.

[0020] When the force plate moves downward under the action of the gravity of the oil, it will drive the rotating frame to move downward. The rotating frame moves downward and contacts the friction plate. The friction plate moves back and forth with the push frame, so that the friction plate drives the rotating frame to rotate. The rotating frame rotates to scrape out the oil residue on the force plate. Since the rotating frame is an inclined surface, the mixture of oil residue and oil can quickly flow out of the force plate and be separated on the filter frame. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0033] Example 1: A residual oil extraction device, see Figure 1-Figure 3 As shown, it includes a sedimentation box 1, on which a filter outer barrel 2 is provided, a discharge port is opened at the lower side of the filter outer barrel 2, a filter inner barrel 3 is rotatably connected in the filter outer barrel 2, a filter frame 4 is fixedly connected to the lower side of the sedimentation box 1, the inner diameter of the hole on the filter frame 4 is smaller than the inner diameter of the hole on the filter inner barrel 3, the filter frame 4 is provided with symmetrically distributed collecting boxes, the filter outer barrel 2 is installed with evenly distributed vibrators 5, a slide 6 is slidably connected in the filter outer barrel 2, the slide 6 is a circular ring with an L-shaped cross section, the slide 6 is located outside the filter inner barrel 3, and the filter inner barrel 3 is on the filter inner barrel 3. A first spring 7 is sleeved, a fixing rod 8 is fixedly connected to the sedimentation box 1, a force plate 9 is slidably connected to the fixing rod 8, a pressure sensor 11 is arranged at the bottom of the fixing rod 8, a second spring 10 is connected between the force plate 9 and the pressure sensor 11, a first electric push rod 12 is installed on the sedimentation box 1, the pressure sensor 11 is electrically connected to the first electric push rod 12, a push plate 13 is fixedly connected to the telescopic end of the first electric push rod 12, the push plate 13 is slidably connected to the sedimentation box 1, and the two ends of the first spring 7 are respectively connected to the slide 6 and the push plate 13.

[0034] When it is necessary to extract the residual oil, first pour the oil residue into the filtering outer barrel 2, and then start the vibrator 5. The vibration of the vibrator 5 promotes the separation of the oil residue and the oil. At the same time, the oil in the oil residue is separated by the filtering inner barrel 3. The oil residue accumulates on the slide 6, and the gravity of the oil residue drives the slide 6 to move downward, so that the first spring 7 is compressed. When the slide 6 moves downward to the top surface and is flush with the lowest point of the discharge port of the filtering outer barrel 2, the discharge port of the filtering outer barrel 2 is in an open state, so that the oil residue after oil filtering is discharged from the discharge port, and the filtered oil enters the inside of the filtering inner barrel 3, and then drips onto the force-bearing plate 9, flows from the force-bearing plate 9 to the filter frame 4, is filtered again through the filter frame 4, and finally enters the lower part of the sedimentation box 1.

[0035] When oil drops onto the force-bearing plate 9, the gravity of the oil causes the force-bearing plate 9 to move downward, thereby compressing the second spring 10 and triggering the pressure sensor 11. Since the oil in the oil residue that is more difficult to separate is separated and filtered out more slowly, less oil drips in the same period of time, so that the pressure sensed by the pressure sensor 11 is less than a preset value. The pressure sensor 11 controls the first electric push rod 12 to start through the control module. The telescopic end of the first electric push rod 12 drives the push plate 13 to move upward, thereby driving the slide 6 to move upward through the first spring 7, so that the discharge port of the filter outer barrel 2 is reduced, thereby reducing the amount of oil residue flowing out of the discharge port and prolonging the time that the oil residue stays in the filter outer barrel 2, thereby improving the efficiency of the oil residue filtering oil.

[0036] When more oil drips onto the force-bearing plate 9, it means that the oil in the oil residue is easier to separate and the filtering speed is faster. At this time, it is necessary to increase the outflow speed of the oil residue to improve the oil filtering efficiency. Since there is more oil on the force-bearing plate 9, when the pressure value sensed by the pressure sensor 11 reaches a preset value, the pressure sensor 11 controls the telescopic end of the first electric push rod 12 to contract through the control module, thereby driving the push plate 13 to move downward, so that the first spring 7 drives the slide 6 to move downward, so that the discharge port of the filter outer barrel 2 becomes larger, so that more oil residue flows out of the discharge port, thereby realizing rapid oil filtering and increasing the oil filtering speed of the oil residue.

[0037] In summary, the gravity of the oil dripping onto the force-bearing plate 9 causes the second spring 10 to squeeze the pressure sensor 11. Since the oil will slowly flow out from the outside of the force-bearing plate 9, when the speed of the oil dripping is much greater than the speed of the oil flowing out from the outside of the force-bearing plate 9, the oil on the force-bearing plate 9 will increase, causing the pressure sensor 11 to control the telescopic end of the first electric push rod 12 to shorten through the control module, thereby causing the slide 6 to move downward, causing the discharge port of the filter outer barrel 2 to become larger, thereby accelerating the speed at which the oil residue flows out of the discharge port of the filter outer barrel 2 and improving the efficiency of filtering the oil residue; when the speed of the oil dripping is less than the speed at which the oil flows out from the outside of the force-bearing plate 9, the oil on the force-bearing plate 9 decreases, causing the pressure sensor 11 to control the telescopic end of the first electric push rod 12 to extend through the control module, thereby driving the slide 6 to move upward, causing the discharge port of the filter outer barrel 2 to become smaller, thereby slowing down the speed at which the oil residue flows out of the discharge port of the filter outer barrel 2 and improving the quality of filtering the oil residue.

[0038] Embodiment 2: Based on embodiment 1, see Figure 4 As shown, it also includes a rotating component for rotating and discharging oil, the rotating component is arranged in the sedimentation box 1, and the rotating component includes a motor 14, the motor 14 is installed in the sedimentation box 1, and a pulley assembly 15 is arranged between the output shaft of the motor 14 and the filter inner barrel 3, the filter outer barrel 2 is fixedly connected with a liquid guide plate 16, the projection of the liquid guide plate 16 from top to bottom is S-shaped, and an inwardly inclined guide plate is arranged on the lower side of the liquid guide plate 16, the liquid guide plate 16 is located in the filter inner barrel 3 and is rotatably connected to the filter inner barrel 3.

[0039] In order to increase the speed of separation of oil residue and oil, when separating oil residue and oil, the operator starts the motor 14, and the output shaft of the motor 14 rotates to drive the filter inner barrel 3 to rotate through the pulley assembly 15. The rotation of the filter inner barrel 3 causes the oil residue to move slightly, thereby facilitating the separation of oil in the oil residue. Since the filter inner barrel 3 is provided with the liquid guide plate 16, the liquid guide plate 16 contacts the inner wall of the rotating filter inner barrel 3, and can scrape and gather the oil that has penetrated into the filter inner barrel 3 but has not yet gathered, and the oil drips through the liquid guide plate 16 on the lower side of the liquid guide plate 16, thereby promoting the oil dripping process.

[0040] See also Figure 5 and Figure 6As shown, it also includes a blocking component for changing the discharge state of the oil residue, the blocking component is arranged on the filtering outer barrel 2, the blocking component includes evenly distributed fixing frames 17, the evenly distributed fixing frames 17 are fixed to the filtering outer barrel 2, a card block 18 is slidably connected in the fixing frame 17, a third spring 19 is connected between the card block 18 and the adjacent fixing frame 17, the fixing frame 17 is slidably connected with a symmetrically distributed baffle 20, the side of the card block 18 close to the baffle 20 is an inclined surface, the card block 18 is squeezed and matched with the baffle 20, and a fourth spring 19 is connected between the baffle 20 and the adjacent fixing frame 17. Spring 21, a bracket 22 is slidably connected to the fixed frame 17, a symmetrically distributed protrusion is provided on the side of the clamping block 18 close to the bracket 22, a slope is provided on the upper side of the clamping block 18, the protrusion on the clamping block 18 is squeezed and matched with the slope on the bracket 22, a uniformly distributed protective cover 24 is fixed in the sedimentation box 1, a fixed frame 23 is slidably connected in the protective cover 24, a V-shaped groove is provided on the side of the clamping frame 22 close to the fixed frame 23, the V-shaped groove of the clamping frame 22 is squeezed and matched with the fixed frame 23, and the side of the fixed frame 23 close to the slide 6 is an arc surface.

[0041] When the oil residue enters the filter outer barrel 2, the slide 6 is driven downward by gravity, and the slide 6 squeezes the block 18 to move outward, so that the third spring 19 is compressed, and the block 18 moves outward to squeeze the bracket 22 upward, so that the fixed frame 23 is squeezed inward. When the slide 6 moves downward and passes over the block 18, the third spring 19 drives the block 18 to move inward and reset. However, since the oil residue squeezes the block 18, the block 18 It cannot be completely reset. When the slide 6 continues to move downward, it will squeeze the fixed frame 23, so that the fixed frame 23 moves outward, thereby driving the clamping frame 22 to move downward, so that the clamping frame 22 squeezes the clamping block 18 to move outward and reset. In this way, the slide 6 clamps the fixed frame 23, and then clamps the clamping block 18, so that the clamping block 18 blocks the falling oil residue, thereby changing the falling path of the oil residue, and then changing the state of the oil residue discharging, which is convenient for the oil residue to be separated from the oil faster.

[0042] See also Figure 7As shown, it also includes a discharge component for adjusting the discharge amount, the discharge component is arranged on the filter outer barrel 2, and the discharge component includes a pressure sensor 25, and the pressure sensor 25 is installed on the side of the filter outer barrel 2 close to the discharge port, and a second electric push rod 251 is installed on the side of the filter outer barrel 2 close to the pressure sensor 25, the pressure sensor 25 is electrically connected to the second electric push rod 251, and a retaining ring 26 is fixed to the telescopic end of the second electric push rod 251, and the retaining ring 26 is located on the outside of the filter outer barrel 2, and the height of the retaining ring 26 is less than the height of the discharge port of the filter outer barrel 2.

[0043] When too much oil residue accumulates on the lower side of the filter outer barrel 2, the pressure sensed by the pressure sensor 25 reaches a preset value, and the control module will control the telescopic end of the second electric push rod 251 to contract, so that the retaining ring 26 moves upward, thereby expanding the discharge port of the filter outer barrel 2, so that the accumulated oil residue can be discharged quickly. After the accumulated oil residue is discharged, the pressure value of the normal flow of oil residue is within the normal range. The pressure sensor 25 controls the telescopic end of the second electric push rod 251 to extend through the control module, thereby driving the retaining ring 26 to move downward and shrinking the discharge port of the filter outer barrel 2.

[0044] See also Figure 8 As shown, it also includes an anti-blocking component to prevent the filter frame 4 from being blocked. The anti-blocking component is arranged in the sedimentation box 1, and the anti-blocking component includes an eccentric wheel 27. The eccentric wheel 27 is connected to the output shaft of the motor 14. The eccentric wheel 27 is rotatably connected to a pull rod 28 on the side close to the filter frame 4. The pull rod 28 is rotatably connected to a push frame 29, and the push frame 29 is slidably connected to the filter frame 4.

[0045] Since there is still some fine oil residue in the oil flowing out from the filter inner barrel 3 to the force-bearing plate 9, the filter frame 4 can filter and block this part of the fine oil residue above the filter frame 4. However, excessive accumulation of fine oil residue will cause the filter frame 4 to be blocked, affecting the speed of oil separation. Therefore, when the output shaft of the motor 14 rotates, it will drive the pull rod 28 to swing, so that the pull rod 28 pulls the push frame 29 to move back and forth, pushing the fine oil residue on the filter plate to the collection frames on both sides, thereby preventing the fine oil residue from clogging the filter frame 4 and affecting the oil separation.

[0046] See also Figure 9-10As shown, it also includes a cleaning component to prevent material residue from affecting the judgment of the pressure sensor 11. The cleaning component is arranged on the force-bearing plate 9. The cleaning component includes a friction plate 30. The friction plate 30 is arranged on the push frame 29. A rotating frame 31 is rotatably connected to the force-bearing plate 9. The rotating frame 31 is composed of three I-shaped rotating blocks combined into a "human" shape and a vertical rod with a friction wheel. The I-shaped rotating block has an inclined surface. The rotating frame 31 passes through the force-bearing plate 9 and cooperates with the friction plate 30.

[0047] Since the force-bearing plate 9 is initially in contact with the preliminarily separated oil, part of the oil residue in the preliminarily separated oil will directly settle on the force-bearing plate 9, so that there is not only oil but also oil residue on the force-bearing plate 9, affecting the judgment of the pressure sensor 11. Therefore, when the force-bearing plate 9 moves downward under the gravity of the oil, it will drive the rotating frame 31 to move downward. The rotating frame 31 moves downward and contacts the friction plate 30. The friction plate 30 follows the push frame 29 to move back and forth, so that the friction plate 30 drives the rotating frame 31 to rotate. The rotating frame 31 rotates to scrape out the oil residue on the force-bearing plate 9. Since the I-shaped rotating block of the rotating frame 31 is an inclined surface, the mixture of oil residue and oil can quickly flow out of the force-bearing plate 9 and be separated on the filter frame 4.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
