Description

Technical Field

[0001] This invention relates to the technical field of oil extraction, and in particular to an energy-saving oil extraction dewaxing device. Background Technology

[0002] During oil extraction, paraffin wax accumulates and deposits on the inner and outer walls of the well, forming wax deposits. Wells with severe wax deposits need to have their tubing cleaned, otherwise the oil extraction progress will be severely affected, and even safety accidents may occur.

[0003] During oil extraction, some oil pipes covered with paraffin wax are dismantled and placed in an open area. After dewaxing, they can be reused. In existing technologies, the following methods are often used: a handheld spray gun is used to spray high-pressure steam onto the oil pipes to heat them, and then a brush is used to clean them. Even if some parts are automated, this method is not only prone to injuring operators, but also inefficient and needs to be improved. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides an energy-saving oil extraction and dewaxing device with a simple structure that can automatically flush the inner and outer walls of the oil pipe, reduce the labor intensity of the operator, and improve the cleaning efficiency of the oil pipe.

[0005] An energy-saving oil extraction and dewaxing device of the present invention includes: a hollow box with an open top, and support components for supporting oil pipes are symmetrically arranged on both sides of the box along the length direction.

[0006] Along the length direction, both sides of the box are equipped with a brushing mechanism for brushing the outer wall of the oil pipe.

[0007] Along the length direction, both sides of the box are equipped with sealing mechanisms to seal the ends of the oil pipes, and a filling component is provided on one side of the box, while a brushing mechanism is provided on the other side to clean the inner wall of the oil pipes.

[0008] The present invention is further improved in that the support assembly includes two sets of lifting assemblies arranged symmetrically.

One end of the shaft tube is fixed with a fixing ring. Several connecting shafts are rotatably mounted in a circular array on the fixing ring. One end of the connecting shaft is fixed with an adjusting arm. The other end of the adjusting arm is rotatably mounted with a roller brush.

[0011] In a further improvement of the present invention, a second connecting shaft is rotatably mounted on the first connecting shaft. The second connecting shaft is connected to the first roller brush via a chain drive. Each second connecting shaft is connected via a chain drive. A first motor is fixed to the fixed ring. A first sprocket for driving the second chain to rotate is fixed to the output end of the first motor.

[0012] The lifting frame is equipped with a second motor, which is connected to the shaft tube for transmission.

[0013] In a further improvement, each connecting shaft is connected by a chain three. A fixed ring is rotatably mounted on the connecting shaft three. The connecting shaft three is fixed with a sprocket two and a gear that cooperate with the chain three. The fixed ring is elastically slidably connected with a locking tooth that meshes with the gear.

[0014] The invention is further improved by rotatably installing a drive tube on one side of the box along the length direction. The drive tube is connected to one of the rotating shafts. The drive tube has a through hole, which includes a spiral segment 1, a straight segment 1, a spiral segment 2, and a straight segment 2 that are connected.

[0015] A drive tube 2 is rotatably mounted on one side of the housing. The drive tube 2 is connected to another rotating shaft. The drive tube 2 has a through hole 2, which includes a straight segment 3, a spiral segment 3, a straight segment 4, a spiral segment 5, and a straight segment 5 that are connected.

[0016] One end of the gantry frame is fixed with a drive shaft 1 that passes through a through hole 1, and the other end is fixed with a drive shaft 2 that passes through a through hole 2.

[0033] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0034] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0035] like Figures 1 to 10 As shown, an energy-saving oil extraction and dewaxing device of the present invention includes: a hollow box 1 with an open top, and support components for supporting oil pipes are symmetrically arranged on both sides of the box 1 along the length direction.

[0036] Along the length direction, both sides of the box body 1 are equipped with a brushing mechanism for brushing the outer wall of the oil pipe.

[0037] Along the length direction, both sides of the box 1 are provided with a sealing mechanism to seal the end of the oil pipe, and a filling component is provided on one side of the box 1, and a brushing mechanism 2 for cleaning the inner wall of the oil pipe is provided on the other side.

[0038] In this embodiment, during use, the oil pipe to be dewaxed is placed on the support assembly and positioned approximately in the center. Then, the sealing mechanisms on both sides are operated to block both sides of the oil pipe. Steam is then filled into the oil pipe by the filling assembly. Finally, the first and second brushing mechanisms are operated to brush the wax on the outer and inner walls of the oil pipe, thereby removing the wax from the oil pipe.

[0039] The present invention may be further improved, such as Figure 1 and Figure 3 As shown, the support assembly includes two symmetrically arranged sets of lifting components, such as... Figures 8 to 10 As shown, the lifting assembly includes two fixed plates 2 fixedly connected to the housing 1. The fixed plates 2 have vertical holes 3 and inclined holes 4 that communicate with each other. A moving shaft 5 moves along the vertical holes 3 and inclined holes 4. A support block 6 for supporting the oil pipe is fixed at one end of the moving shaft 5. More specifically, a transition frame 7 is fixed between the moving shaft 5 and the support block 6 to increase the space between the fixed plates 2 and the oil pipe. The support block 6 is V-shaped to better position the oil pipe in the front-back direction, eliminating the need for manual positioning.

[0040] like Figures 8 to 10 As shown, a slider 8 slides horizontally on the fixed plate 2, and a slider 9 slides vertically on the slider 8. The slider 9 is fixedly connected to the moving shaft 5. A rotating shaft 10 is rotatably installed on the two fixed plates 2. A drive wall is fixed at both ends of the rotating shaft 10. The drive arm 11 is slidably connected to the other end of the moving shaft 5. More specifically, the drive arm 11 has an elongated hole through which the moving shaft 5 passes.

[0041] In this embodiment, as Figures 8 to 10 As shown, there are two sets of lifting components, one for standby and one for use. Since the support block 6 will hinder the movement of the first brushing mechanism when it moves, the other lifting component should support the oil pipe before the first brushing mechanism moves to the lifting component, and this lifting component should be detached from the oil pipe.

[0042] like Figure 8 As shown, when the support block 6 needs to be disengaged from the oil pipe, the rotating shaft 10 and the drive arm 11 rotate clockwise around the axis of the rotating shaft 10. Since the moving shaft 5 passes through the elongated hole on the drive arm 11, the moving shaft 5 will move along the vertical hole 3 and the inclined hole 4. When the moving shaft 5 moves along the vertical hole 3, it will drive the transition frame 7, the second slider 9 and the support block 6 to move vertically downward, so that the support block 6 is disengaged from the oil pipe. During this process, the second slider 9 moves vertically downward relative to the first slider 8. Since the second slider 9 will not rotate and the moving shaft 5 is fixedly connected to the second slider 9, the moving shaft 5 and the support block 6 will not rotate either.

[0043] Then the moving shaft 5 moves along the inclined hole 4. During this process, the movement of the support block 6, the second slider 9 and the moving shaft 5 can be decomposed into lateral movement and longitudinal movement, so that the support block 6 can quickly move away from the oil pipe and increase the space. When moving laterally, both the first slider 8 and the second slider 9 move relative to the fixed plate 2, which will not cause the moving shaft 5 to rotate.

[0044] Similarly, when it is necessary to support the oil pipe, simply reverse the rotating shaft 10.

[0045] The present invention may be further improved, such as Figure 2 , Figures 4 to 6 As shown, the washing mechanism includes a moving mechanism 12 installed on both sides of the housing 1. More specifically, the moving mechanism 12 is driven by a synchronous belt, and the output end of the moving mechanism 12 is a gantry 13, with the synchronous belt connected to the gantry 13.

[0046] The gantry frame 13 is equipped with a lifting mechanism 14. More specifically, the lifting mechanism 14 adopts a screw structure. The output end of the lifting mechanism 14 is fixed with a lifting frame 15. The lifting frame 15 is rotatably mounted with a shaft tube 16 via a bearing. One end of the shaft tube 16 is fixed with a fixing ring 17. The fixing ring 17 is rotatably mounted with several connecting shafts 18 in a circular array. One end of the connecting shaft 18 is fixed with an adjusting arm 19. The other end of the adjusting arm 19 is rotatably mounted with a roller brush 20.

[0047] The present invention may be further improved, such as Figures 5 to 6 As shown, a connecting shaft 21 is coaxially mounted on a connecting shaft 18. The connecting shaft 21 and the roller brush 20 are connected by a chain 22. Each connecting shaft 21 is connected by a chain 56. A motor 23 is fixed on a fixing ring 17. A sprocket 24 for driving the chain 56 is fixed on the output end of the motor 23. When the motor 23 is powered on, it drives the sprocket 24 to rotate, which in turn drives the chain 56 to rotate. The chain 56 drives the connecting shaft 21 to rotate. Under the drive of the chain 22, each roller brush 20 also rotates simultaneously.

[0048] The lifting frame 15 is fixed with a second motor 25, which is connected to the shaft tube 16 for transmission. More specifically, the second motor 25 and the shaft tube 16 are connected through two meshing gears 29. When the second motor 25 is powered on, it drives the shaft tube 16 and the components on the shaft tube 16 to rotate through the two meshing gears 29, so that the first roller brush 20 can revolve.

[0049] In summary, by simultaneously activating motor 23 and motor 25, the roller brush 20 can rotate on its own axis and revolve around the sun.

[0050] The present invention may be further improved, such as Figures 6 to 7As shown, each connecting shaft 18 is connected by a chain 26. A connecting shaft 27 is rotatably mounted on a fixing ring 17. A sprocket 28 and a gear 29 that cooperate with the chain 26 are fixed on the connecting shaft 27. A locking tooth 30 that meshes with the gear 29 is elastically slidably connected to the fixing ring 17.

[0051] In this embodiment, as Figure 7 As shown, when the locking tooth 30 meshes with the gear 29, the gear 29, the sprocket 28 and the connecting shaft 27 cannot rotate, and thus each connecting shaft 18 cannot move, which serves to fix each connecting shaft 18.

[0052] When the outer diameter of the oil pipe changes, in order for the roller brush 20 to adapt to the outer diameter of the oil pipe, the sliding locking tooth 30 is disengaged from the gear 29. Then, the connecting shaft 27 and the sprocket 28 are rotated to make the chain 26 rotate, thereby driving the connecting shaft 18 and the swing arm to rotate around the axis of the connecting shaft 18, so that the roller brush 20 is in close contact with the outer wall of the oil pipe. Then, the locking tooth 30 is released, and the nearest suitable tooth is selected to insert the locking tooth 30.

[0053] The present invention may be further improved, such as Figures 8 to 9 As shown, along the length direction, a drive tube 31 is rotatably installed on one side of the housing 1. The drive tube 31 is connected to one of the rotating shafts 10. The drive tube 31 has a through hole 1. The through hole 1 includes a spiral segment 32, a straight segment 33, a spiral segment 34, and a straight segment 35. The spiral segment 32 and the spiral segment 34 rotate in opposite directions. The straight segments 33 and 35 are both arranged parallel to the axis of the drive tube 31.

[0054] A drive tube 2 36 is rotatably mounted on one side of the housing 1. The drive tube 2 36 is connected to another rotating shaft 10. The drive tube 2 36 has a through hole 2. The through hole 2 includes a straight segment 3 37, a spiral segment 3 38, a straight segment 4 39, a spiral segment 40, and a straight segment 5 41 that are connected. The spiral segment 3 38 and the spiral segment 40 rotate in opposite directions. The straight segments 3 37, 4 39, and 5 41 are all arranged parallel to the axis of the drive tube 2 36.

[0055] One end of the gantry frame 13 is fixed with a drive shaft 42 passing through a through hole 1, and the other end is fixed with a drive shaft 43 passing through a through hole 2.

[0056] In this embodiment, as Figure 8 As shown, at this time, the lifting assembly near the roller brush 20 supports the oil pipe, while the lifting assembly away from the roller brush 20 moves away from the oil pipe.

[0057] When the moving mechanism 12 drives the gantry 13, drive shaft 1 42 and drive shaft 2 43 to move, drive shaft 1 42 first passes through spiral section 1 32 and drive shaft 2 43 passes through straight section 3 37. When drive shaft 1 42 passes through spiral section 1 32, it causes drive tube 1 31 to rotate, thereby driving the rotating shaft 10 away from the sealing component to rotate, so that the support block 6 away from the sealing component first supports the oil pipe. When drive shaft 2 43 passes through straight section 3 37, it does not cause drive tube 2 36 to rotate. The support block 6 on the side closer to the sealing component keeps supporting the oil pipe.

[0058] Then, drive shaft 1 42 passes through straight section 1 33, drive shaft 2 43 passes through spiral section 3 38, straight section 4 39 and spiral section 4 40. When drive shaft 1 42 passes through straight section 1 33, it will not cause drive tube 1 31 to rotate. When drive shaft 2 43 passes through spiral section 3 38, it will cause the rotating shaft 10 near the sealing assembly to rotate, causing the support block 6 on the sealing assembly side to detach from the oil pipe. When drive shaft 2 43 passes through straight section 4 39, the support block 6 near the sealing assembly side remains detached from the oil pipe. When drive shaft 2 43 passes through spiral section 4 40, the support block 6 near the sealing assembly side supports the oil pipe.

[0059] In the two processes mentioned above, the roller brush 20 brushes the area between the end of the oil pipe and the two support blocks 6.

[0060] Then, drive shaft 42 passes through spiral section 34, drive shaft 43 passes through straight section 41, and when drive shaft 42 passes through spiral section 34, the support block 6 on the side away from the sealing component disengages from the oil pipe, and roller brush 20 brushes the remaining outer wall of the oil pipe.

[0061] During the above process, roller brush 20 brushes the remaining parts of the oil pipe.

[0062] The present invention may be further improved, such as Figure 4 As shown, the sealing mechanism includes a cylinder 44 that can slide along the height direction. A hollow tube 45 is fixed at the output end of the cylinder 44, and an expansion ring 46 is provided at the end of the hollow tube 45 near the oil pipe.

[0063] In this embodiment, as Figure 4 As shown, the height of cylinder 44 can be adjusted to accommodate oil pipes of different specifications. After the oil pipe is placed on the support block 6, cylinder 44 is operated to move the hollow tube 45 and the expansion ring 46. After the expansion ring 46 extends into the end of the oil pipe, cylinder 44 is stopped, and then air is injected into the expansion ring 46 so that the expansion ring 46 is tightly attached to the inner wall of the oil pipe.

[0064] The present invention may be further improved, such as Figures 1 to 4As shown, the second brushing mechanism includes a second moving mechanism 47 that slides on one side of the housing 1. More specifically, the bottom of the second moving mechanism 47 is driven by a hydraulic cylinder 48 to lift and lower, in order to adapt to oil pipes of different diameters. The second moving mechanism 47 adopts a screw structure.

[0065] The output end of the second moving mechanism 47 is fixed with an extension rod 49. One end of the extension rod 49 is fixed with a motor 3 50. The other end of the extension rod 49 passes through the hollow tube 45. In order to prevent steam leakage, a sealing ring is installed between the extension rod 49 and the hollow tube 45, and a roller brush 2 51 is installed at this end.

[0066] In this embodiment, the size of the roller brush 51 should be changed according to the inner diameter of the oil pipe. When in use, the moving mechanism is operated to move the extension rod 49, the motor 3 50, and the roller brush 51 relative to the oil pipe, and at the same time the motor 3 50 is turned on to make the roller brush 51 rotate. The inside of the oil pipe is in a steam environment, and the roller brush 51 brushes the inner wall, so that the wax is quickly removed from the oil pipe.

[0067] The present invention may be further improved, such as Figure 1 As shown, the filling assembly includes a hose 52 that communicates with another hollow tube 45;

[0068] In this embodiment, the other end of the hose 52 is connected to external steam or water, and a pressure gauge can also be installed on the hose 52 to detect the pressure inside the oil pipe.

[0069] The present invention may be further improved, such as Figures 3 to 4 As shown, the first scrubbing mechanism also includes a winding shaft 53 rotatably mounted on the housing 1, and an annular tube 54 fixed on the lifting frame 15. The annular tube 54 is coaxially arranged with the shaft tube 16. The inner wall of the annular tube 54 is equipped with a nozzle. The winding shaft 53 is wound with a second flexible hose 55. The second flexible hose 55 is connected to the annular tube 54. Steam or water is introduced into the second flexible hose 55. How external steam or water is introduced into the second flexible hose 55 is existing technology and will not be explained further.

[0070] In this embodiment, when the gantry 13 moves, external steam flows along the second hose 55 and the annular pipe 54 and is finally sprayed out along the nozzle onto the outer wall of the oil pipe, keeping the outer wall of the oil pipe at a high temperature, so that the wax on the outer wall of the oil pipe can be removed from the oil pipe more quickly. When the gantry 13 moves, the motor 4 installed at the end of the winding shaft 53 automatically winds up the second hose 55.

[0071] When using this invention, as Figure 1 and Figure 3As shown, two support blocks 6 near the sealing component support the oil pipe. The position of cylinder 44 is adjusted according to the height of the oil pipe. Cylinder 44 is operated to move hollow pipe 45 and expansion ring 46. After the expansion ring 46 extends to the end of the oil pipe, cylinder 44 is stopped. Then, air is injected into the expansion ring 46 so that the expansion ring 46 is tightly attached to the inner wall of the oil pipe. Then, steam is injected into the oil pipe through hose 52.

[0072] Then, activate the moving mechanism 12 and the moving mechanism 2 47. When the moving mechanism 2 47 is activated, the motor 3 50 is activated at the same time to make the roller brush 2 51 rotate. The inside of the oil pipe is in a steam environment. With the roller brush 2 51 brushing the inner wall, the wax is quickly removed from the oil pipe. After the inner wall of the oil pipe is cleaned, open the sealing component on one side and let water flow into the hose 1 52. The water will flush the inner wall of the oil pipe clean, and the sewage will flow into the box 1. A pipe is set at the end of the box 1 to discharge the sewage.

[0073] Before starting the moving mechanism 12, according to the pipe diameter, operate the oil cylinder 48 to make the shaft tube 16 coaxial with the oil pipe, then rotate the connecting shaft 3 27, which drives the connecting shaft 18 and the swing arm to rotate around the axis of the connecting shaft 18, so that the roller brush 120 is in close contact with the outer wall of the oil pipe. Then start the motor 1 23 and the motor 2 25, so that the roller brush 120 rotates on its own axis and revolves around the center.

[0074] After the moving mechanism 12 is opened, when the moving mechanism 12 drives the gantry 13, drive shaft 1 42 and drive shaft 2 43 to move, drive shaft 1 42 first passes through spiral section 1 32 and drive shaft 2 43 passes through straight section 3 37. When drive shaft 1 42 passes through spiral section 1 32, it causes drive tube 1 31 to rotate, thereby driving the rotating shaft 10 away from the sealing component to rotate, so that the support block 6 away from the sealing component first supports the oil pipe. When drive shaft 2 43 passes through straight section 3 37, it will not cause drive tube 2 36 to rotate. The support block 6 on the side close to the sealing component keeps supporting the oil pipe.

[0075] Then, drive shaft 1 42 passes through straight section 1 33, drive shaft 2 43 passes through spiral section 3 38, straight section 4 39 and spiral section 4 40. When drive shaft 1 42 passes through straight section 1 33, it will not cause drive tube 1 31 to rotate. When drive shaft 2 43 passes through spiral section 3 38, it will cause the rotating shaft 10 near the sealing assembly to rotate, causing the support block 6 on the sealing assembly side to detach from the oil pipe. When drive shaft 2 43 passes through straight section 4 39, the support block 6 near the sealing assembly side remains detached from the oil pipe. When drive shaft 2 43 passes through spiral section 4 40, the support block 6 near the sealing assembly side supports the oil pipe.

[0076] In the two processes mentioned above, the roller brush 20 brushes the area between the end of the oil pipe and the two support blocks 6.

[0077] Then, drive shaft 42 passes through spiral section 34, drive shaft 43 passes through straight section 41, and when drive shaft 42 passes through spiral section 34, the support block 6 on the side away from the sealing component disengages from the oil pipe, and roller brush 20 brushes the remaining outer wall of the oil pipe.

[0078] During the above process, roller brush 20 brushes the remaining parts of the oil pipe. After brushing, water can be introduced into hose 55 to clean the outer wall of the oil pipe.

[0079] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
