It is mainly composed of hydrocarbons and is widely used in fuel, chemical raw materials, and various industrial and daily life products. Petroleum extraction refers to the act of digging and extracting petroleum where it is stored.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0031] Example:

[0032] Reference Figure 1-Figure 8 , an oil production equipment, including a processing box 1, a primary filter bucket 2 is fixedly connected to the top of the inner cavity of the processing box 1, a liquid guide bucket 21 is fixedly connected to the top of the processing box 1, the primary filter bucket 2 is connected to the inner cavity of the liquid guide bucket 21, and also includes: a primary filter screen 3, the primary filter screen 3 is installed in the primary filter bucket 2 of the component, the bottom of the primary filter screen 3 is inclined, so as to accelerate the flow of oil, and at the same time enable the intercepted solid impurities to slide downward along the slope to avoid clogging of its filter holes by oil impurities, thereby ensuring the use effect of the primary filter screen 3, wherein the primary filter bucket 2 is provided with a shaking screen part for driving the primary filter screen 3 to vibrate up and down; a fine filter plate 4, the fine filter plate 4 is fixed in the processing box 1, wherein the top of the fine filter plate 4 is connected to the oblique bottom of the liquid guide bucket 21 through a liquid guide pipe 22, and a fine filter part for filtering the crude oil again is provided in the fine filter plate 4.

[0033] Reference Figure 1-Figure 4 The shaking screen part includes four groups of piston sleeves 5, which are symmetrically fixed on the outer wall of the primary filter bucket 2, and the outer wall of the telescopic end of the piston sleeve 5 is sleeved with a shaking screen spring 51. The primary filter 3 is plugged and fixed on the telescopic end of the four groups of piston sleeves 5. A driving disk 52 is rotatably connected to the outer wall of the primary filter bucket 2, and a lifting rocker 53 is rotatably connected to the driving disk 52. The top of the lifting rocker 53 is rotatably connected to a lifting plate 532 through a hinge seat 531. The top of the lifting plate 532 is fixedly connected to the bottom of the side wall of the primary filter 3. A driving motor 54 is fixedly connected to the top of the processing box 1, and the rotating shaft of the driving motor 54 is connected to the rotating shaft of the driving disk 52 through a first pulley group 541.

[0034] Through the arrangement of the above structure, the driving motor 54 is turned on, and the driving disk 52 is driven to rotate through the transmission action of the first pulley group 541, so that the lifting rocker 53 lifts and lowers the lifting plate 532 reciprocatingly. At this time, in conjunction with the arrangement of the vibration screen spring 51, the primary filter screen 3 pulls the telescopic end of the piston sleeve 5 to lift and lower reciprocatingly, thereby generating a reciprocating up and down shaking action, so that the oil passes through the primary filter screen 3 quickly, while the larger impurities in the oil are filtered out and retained in the primary filter screen 3. At the same time, the above shaking action can effectively prevent the larger impurities in the oil from clogging the primary filter screen 3, thereby effectively improving the filtration efficiency.

[0035] Reference Figure 1-Figure 4 The bottoms of the cavities of the two groups of piston sleeves 5 on the same side are connected through an exhaust pipe 6, the input end of the exhaust pipe 6 is connected to the inner cavity of the processing box 1, and a one-way valve is arranged in the exhaust pipe 6; the side walls of the cavities of the two groups of piston sleeves 5 on the same side are connected through an exhaust pipe 61, and a one-way valve is arranged in the exhaust pipe 61, and the exhaust pipes 61 on both sides are connected through an air guide pipe 62, and the output end of the air guide pipe 62 is rotatably connected to a blowing pipe 63, and the output end of the blowing pipe 63 faces the bottom of the primary filter screen 3.

[0036] It should be noted that the one-way valve in the exhaust pipe 6 can only allow the gas in the processing box 1 to enter the cavity of the piston sleeve 5; the one-way valve in the exhaust pipe 61 can only allow the gas in the cavity of the piston sleeve 5 to be discharged along the blowing pipe 63.

[0037] Through the arrangement of the above-mentioned structure, when the lifting rocker 53 pushes the primary filter screen 3 to move upward with the telescopic end of the piston sleeve 5, a suction effect will be generated at the bottom of the piston sleeve 5 cavity, and the one-way valve in the exhaust pipe 6 will be opened at the same time, so that the gas in the processing box 1 is sucked into the piston sleeve 5 cavity, thereby reducing the air pressure in the processing box 1, so that the bubbles quickly overflow from the inside of the oil, effectively improving the bubble removal effect, and effectively improving the oil quality; and when the lifting rocker 53 drives the primary filter screen 3 to move downward, the gas in the piston sleeve 5 cavity will be compressed, thereby opening the one-way valve in the exhaust pipe 61, so that the above-mentioned sucked gas is blown to the bottom of the primary filter screen 3 along the exhaust pipe 61, the air guide pipe 62 and the blowing pipe 63, thereby generating a downward airflow thrust at the top of the primary filter screen 3, so that the oil passes through the primary filter screen 3 more quickly, thereby improving the oil filtering effect.

[0038] Reference Figure 6 , Figure 8 The fine filter unit includes a stirring shaft 7, which passes through the center of the fine filter disk 4 and is rotatably connected to the inner walls of the processing box 1 on both sides. A plurality of groups of filter blades 71 are fixed at equal intervals on the stirring shaft 7 located in the fine filter disk 4. The ends of the filter blades 71 are fixedly connected to blocking arc plates 711, which fit and rotate with the inner wall of the fine filter disk 4. A drain pipe 72 is fixedly connected to the side wall of the fine filter disk 4. The input end of the drain pipe 72 is connected to the bottom of the inner cavity of the fine filter disk 4. A fine filter screen 73 is fixedly connected to the bottom of the side of the fine filter disk 4 away from the drain pipe 72. The end of the stirring shaft 7 is connected to the rotating shaft of the drive motor 54 through a second pulley set 74.

[0039] It should be noted that the setting of the arc blocking plate 711 can firstly realize the intermittent connection between the liquid guide tube 22 and the fine filter plate 4, effectively preventing excessive gas from entering the processing box 1 along the liquid guide tube 22, thereby ensuring the negative pressure exhaust effect; secondly, it can slide and clean the inner arc wall of the fine filter plate 4, thereby ensuring the neatness of the inner arc wall of the fine filter plate 4.

[0040] By setting the above structure, the oil that has been initially filtered will flow into the liquid guide bucket 21, and enter the fine filter disk 4 along with the liquid guide bucket 21 and the liquid guide tube 22. At the same time, through the transmission action of the second pulley group 74, the driving motor 54 will also drive the stirring shaft 7 to rotate, so that the filter blades 71 rotate in the fine filter disk 4. When the blocking arc plate 711 is separated from the output end of the liquid guide tube 22, the oil that has been initially filtered will enter the fine filter disk 4, and pass through multiple groups of rotating filter blades 71 to reach the bottom of the fine filter disk 4, thereby realizing secondary filtration of the oil. Finally, the oil at the bottom of the fine filter disk 4 will continue to pass through the fine filter net 73, and enter the processing box 1 after the third filtration, thereby completing the three-step filtration of the oil, effectively filtering out the impurities contained in the oil, and improving the purity of the oil.

[0041] Reference Figure 5-Figure 7 Among them, a plurality of stirring rods 8 are fixed at equal intervals on the outer wall of the stirring shaft 7, a knocking block 81 is slidably connected to the inner wall of the stirring rod 8, a limiting ring 82 is fixedly connected inside the stirring rod 8, a reset spring 821 is fixedly connected between the knocking block 81 and the limiting ring 82, a pulling groove 83 is opened in the stirring shaft 7, the stirring rod 8 is connected to the inner cavity of the pulling groove 83, a pulling rod 84 is inserted in the pulling groove 83, a pull rope 811 is fixedly connected to the side of the knocking block 81 close to the pulling rod 84, the other end of the pull rope 811 is fixedly connected to the outer wall of the pulling rod 84, a positioning sleeve 85 is fixedly connected to the outer wall of the processing box 1, and a driving pull rod 84 is arranged in the positioning sleeve 85 A movable pulling portion; the end of the stirring rod 8 extends through and into the positioning sleeve 85, and a cross slot 831 is opened inside the pulling groove 83 at one end close to the positioning sleeve 85, and a cross strip 841 is fixedly connected to the outer wall of the pulling rod 84, the cross strip 841 is plugged into the cross slot 831, and the cross strip 841 slides along the cross slot 831; the pulling portion includes two groups of moving magnetic plates 842, the pulling rod 84 extends through and into the positioning sleeve 85, the two groups of moving magnetic plates 842 are fixed on both sides of the end of the pulling rod 84, and fixed magnetic plates 851 are fixedly connected on both sides of the inner wall of the positioning sleeve 85, and the fixed magnetic plates 851 and the moving magnetic plates 842 repel each other magnetically.

[0042] It should be noted that, through the cooperation between the cross inserting strip 841 and the cross slot 831 , the pulling rod 84 and the stirring shaft 7 can rotate synchronously, and at the same time, the pulling rod 84 can slide along the pulling groove 83 .

[0043] By setting the above structure, when the stirring shaft 7 rotates, it will rotate with the moving magnetic plate 842 in the positioning sleeve 85. At this time, with the repulsive effect of the fixed magnetic plate 851 and the moving magnetic plate 842, when the two are in the repulsive area, the moving magnetic plate 842 will be pushed to pull the pulling rod 84 to move to the side away from the fixed magnetic plate 851, thereby pulling each group of knocking blocks 81 to move to the side of the compressed reset spring 821 through the pull rope 811, so as to store force on the reset spring 821. When the fixed magnetic plate 851 and the moving magnetic plate 842 are separated from the repulsive area, the knocking block 81 will be quickly reset under the rebound action of the reset spring 821, thereby hitting the bottom of the inner wall of the stirring rod 8, thereby generating a vibration effect in the oil after three-step filtration, so that the gas contained in the oil floats upward quickly, thereby removing the gas impurities contained in the oil, and further improving the quality of the oil.

[0044] Reference Figure 2 , Figure 4 and Figure 8 An oil inlet pipe 9 is fixedly connected to the side wall of the primary filter bucket 2, and an oil pump 91 is fixedly connected to the oil inlet pipe 9. A mounting groove 31 is opened on the side wall of the primary filter screen 3, and the output end of the oil inlet pipe 9 is plugged into the mounting groove 31; the upper right is arranged that after the primary filter screen 3 is used, the fixed connection between it and the telescopic end of the piston sleeve 5 is released, and the primary filter bucket 2 can be taken out, so as to clean the impurities trapped in the primary filter screen 3, thereby improving the convenience of use.

[0045] Reference Figure 1 , Figure 2 and Figure 6 The bottom of the processing box 1 is fixed and connected with an oil drain pipe 75, and both the oil drain pipe 75 and the sewage pipe 72 are provided with solenoid valves; by opening the corresponding solenoid valves in the oil drain pipe 75 and the sewage pipe 72, the filtered oil in the processing box 1 and the residue retained in the fine filter disc 4 can be discharged respectively, thereby improving the convenience of use.

[0046] Reference Figure 1-Figure 8In the present invention, when in use, the oil pump 91 is turned on to discharge the newly extracted oil into the primary filter screen 3 along the oil inlet pipe 9, and the driving motor 54 is turned on at the same time. Through the transmission action of the first pulley group 541, the driving plate 52 is driven to rotate, so that the lifting rocker 53 and the lifting plate 532 are reciprocated and lifted. At this time, in conjunction with the setting of the vibration screen spring 51, the primary filter screen 3 pulls the telescopic end of the piston sleeve 5 to reciprocate and lift, thereby generating a reciprocating up and down shaking action, so that the oil quickly passes through the primary filter screen 3, and the larger impurities in the oil are filtered out and retained in the primary filter screen 3. At the same time, the above-mentioned shaking action can effectively prevent the larger impurities in the oil from clogging the primary filter screen 3, thereby effectively improving the filtration efficiency; then, after the initial filter 3 is filtered out, the oil is filtered out and retained in the primary filter screen 3. The filtered oil will flow into the liquid guide bucket 21, and enter the fine filter disc 4 along with the liquid guide bucket 21 and the liquid guide tube 22. At the same time, through the transmission action of the second pulley group 74, the drive motor 54 will also drive the stirring shaft 7 to rotate, so that the filter blades 71 rotate in the fine filter disc 4. When the blocking arc plate 711 is separated from the output end of the liquid guide tube 22, the initially filtered oil will enter the fine filter disc 4 and pass through multiple groups of rotating filter blades 71 to reach the bottom of the fine filter disc 4, thereby realizing secondary filtration of the oil. Finally, the oil at the bottom of the fine filter disc 4 will continue to pass through the fine filter net 73, and enter the processing box 1 after the third filtration, thereby completing the three-step filtration of the oil, effectively filtering out impurities contained in the oil, and improving the purity of the oil.

[0047] When the stirring shaft 7 rotates, it will rotate with the moving magnetic plate 842 in the positioning sleeve 85. At this time, with the repulsive effect of the fixed magnetic plate 851 and the moving magnetic plate 842, when the two are in the repulsive area, the moving magnetic plate 842 will be pushed to pull the pulling rod 84 to move to the side away from the fixed magnetic plate 851, thereby pulling each group of knocking blocks 81 to move to the side of the compressed return spring 821 through the pull rope 811, so as to store force on the return spring 821. When the fixed magnetic plate 851 and the moving magnetic plate 842 are separated from the repulsive area, the knocking block 81 will be quickly reset under the rebound effect of the return spring 821, thereby hitting the bottom of the inner wall of the stirring rod 8, thereby generating a vibration effect in the oil after three-step filtration, so that the gas contained in the oil floats upward rapidly; at the same time, the lifting rocker 53 pushes the primary filter screen 3 with the piston During the upward movement of the telescopic end of the sleeve 5, suction will be generated at the bottom of the piston sleeve 5 cavity, and the one-way valve in the exhaust pipe 6 will be opened at the same time, so that the gas in the processing box 1 is sucked into the piston sleeve 5 cavity, thereby reducing the air pressure in the processing box 1, and cooperating with the rotation and vibration of the stirring rod 8, the bubbles will quickly overflow from the inside of the oil, effectively improving the bubble removal effect and effectively improving the oil quality; and when the lifting rocker 53 drives the primary filter screen 3 to move downward, the gas in the piston sleeve 5 cavity will be compressed, thereby opening the one-way valve in the exhaust pipe 61, so that the above-mentioned sucked gas is blown to the bottom of the primary filter screen 3 along the exhaust pipe 61, the air guide pipe 62 and the blowing pipe 63, thereby generating a downward airflow thrust at the top of the primary filter screen 3, so that the oil passes through the primary filter screen 3 more quickly, thereby improving the oil filtering effect.
