Description

Technical Field

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

[0002] Oil is a fluid mineral buried deep underground. During the oil extraction process, oil and gas flow from the reservoir into the bottom of the well and then rise from the bottom of the well to the wellhead. The role of oil in the national economy Oil is an important energy source. Compared with coal, it has the advantages of high energy density, convenient transportation and storage, and less pollution to the atmosphere after combustion. In the composition of world energy consumption, oil has surpassed coal and jumped to the first place.

[0003] As in the prior art, Chinese patent application No. 202021119992.7 is a petroleum extraction device for petroleum residue, including a device main body, a residue box and an oil storage tank are respectively installed on both sides of the top of the device main body. The staff pours the petroleum residue into the auger through the feed port, and then turns on the second motor. The second motor drives the auger to rotate, pushing the petroleum residue inward. Then the staff turns on the cylinder, and the cylinder drives the piston rod to extend, so that one end of the auger rises, and then the oil flows out through the oil outlet. In the process of the auger pushing the residue, the residue is accumulated and squeezed at one end of the oil outlet. As the residue increases, the auger squeezes the residue, thereby squeezing out the oil carried in the residue. Under the action of gravity and pressure, the oil will flow out through the oil outlet and be stored in the oil storage tank, thereby improving the quality and efficiency of oil extraction.

[0004] The device has a loose structure and requires more space. It is also unable to clean impurities in the pipeline, which affects the subsequent discharge of oil.

The sealing plate 412 is rotatably connected to the fixing seat 411, and the sealing plate 412 is used to block the first discharge port 232, the second discharge port 242 or the third discharge port 253 corresponding thereto;

[0048] like Figure 3-6 As shown, the blocking mechanism 4 further includes a pushing assembly 42 , which can respectively rotate the sealing plates 412 of the three blocking assemblies 41 to perform blocking or releasing operations.

A switching plate 4251 is arranged on the spline shaft 423, and the output end of the switching power member 425 is fixedly connected to the switching plate 4251. The switching power member 425 is used to switch the third gear 426 to mesh with it. The third rack 427 provides power, and after the third gear 426 and different third racks 427 are engaged, it can drive different connecting rods 428 and drive the push-pull plate 429 arranged on the connecting rod 428 to move, so that the sealing plate 412 located in the first discharge port 232, the second discharge port 242 or the third discharge port 253 rotates, and controls whether the first discharge port 232, the second discharge port 242 or the third discharge port 253 is sealed according to the rotation degree of the sealing plate 412. The left and right movement of the push-pull plate 429 causes the sealing plate 412 to deflect back and forth.

[0050] The push-pull plate 429 is slidably connected to the processing container 2. A sliding hole is provided on the processing container 2 for the push-pull plate 429 to pass through. The push-pull plate 429 is located in the sliding hole. A push-pull portion 4291 is formed on one end of the push-pull plate 429 close to the sealing plate 412 for contacting the sealing plate 412.

[0053] A sealing portion 4121 is formed on the bottom surface of the sealing plate 412 .

[0054] Electric valves are installed on the first pipe 231, the second pipe 241, the third pipe 251 and the water inlet pipe 252 for automatically controlling the flow of the pipes. The connection between the first pipe 231 and the processing container 2 is located at the lowest point of the crushing chamber 23, the connection between the second pipe 241 and the processing container 2 is located at the lowest point of the extrusion chamber 24, and the connection between the third pipe 251 and the processing container 2 is located at the lowest point of the mixing chamber 25. The first collecting box 11 is used to collect oil, the second collecting box 12 is used to collect a mixture of clean water and oil, and the third collecting box 13 is used to collect the oil residue remaining after the oil is first crushed and then squeezed out and finally mixed with clean water and flows out.

[0055] The remaining oil in the petroleum residue can be better extracted through the crushing chamber 23, the squeezing chamber 24 and the stirring chamber 25.

[0056] A protective plate 34 is fixedly mounted on the top of the processing container 2 , and the protective plate 34 half surrounds the driving component 3 .

[0057] The device further comprises a controller electrically connected to the electric valve, the driving member 3, the push-pull power member 422, and the switching power member 425 for controlling the operation of the device.

[0058] First, the external petroleum residue enters the feed funnel 14, then the feed to the feed funnel 14 is stopped, and the petroleum residue enters the crushing chamber 23 of the processing container 2. At this time, the driving member 3 is activated to crush the petroleum residue in the crushing chamber 23. The oil then flows through the first pipe 231 into the first collection box 11. The filter plate 26 in the first pipe 231 blocks the petroleum residue, making it easier for the oil in the crushed petroleum residue to fall from the first pipe 231 into the first collection box 11. At this time, the first oil extraction operation is carried out;

[0059] After the crushing is completed, the switching power member 425 is activated to mesh the third gear 426 with the first third rack 427. At this time, the push-pull power member 422 is activated to move the first connecting rod 428 to the left, thereby driving the first push-pull plate 429 (i.e., the push-pull plate 429 located in the first discharge port 232) to move to the left, causing the sealing plate 412 to rotate downward and the rotating shaft 413 to rotate. The rotating shaft 413 drives the first gear 414 to rotate. At this time, the first discharge port 232 opens and the oil residue falls into the extrusion chamber 24. At this time, the first gear 414 meshes with the first rack 415, the first rack 415 meshes with the second gear 416, and the second gear 416 meshes with the second rack 417, causing the second rack 417 to move upward, causing the cleaning head 418 to rise and clean the filter plate 26. Then, after the oil residue in the crushing chamber falls into the extrusion chamber 24 , the power member 422 is reversed to push and pull the sealing plate 412 to block the first discharge port 232 . At this time, the cleaning head 418 descends to clean the impurities on the filter plate 26 of the first pipe 9 .

[0060] At this time, new petroleum residue continues to be input into the feed funnel 4.

[0061] Then, the switching power member 425 is activated to mesh the third gear 426 with the second third rack 427. At this point, the driving member 3 is continued to be activated to cause the extrusion mechanism 32 to squeeze the oil residue in the extrusion chamber. The extruded oil falls from the second pipe 241 into the first collection box 11 for collection. This completes the second oil extraction. After the extrusion is completed, the driving member 3 is closed. At this time, the mechanism on the first baffle 21 does not move. At this time, the push-pull power member 422 is activated to move the second connecting rod 428 to the left, thereby driving the second push-pull plate 429 (i.e., the push-pull plate 429 located in the second discharge port 242) to move to the left, causing the sealing plate 412 to rotate downward, opening the second discharge port 242 on the second baffle 22 and delivering the extruded oil into the mixing chamber 25. At this time, clean water is introduced into the water inlet pipe 252 from the outside. The oil residue entering the mixing chamber 25 is then mixed with the clean water. The push-pull power element 422 is then reversed, closing the second discharge port 242 on the second baffle 18. This allows the oil residue in the crushing chamber to fall into the extrusion chamber for processing. After the oil residue and clean water in the mixing chamber are mixed, the electric valve on the third pipe 251 is opened to allow the oil and water mixture to enter the second collection box 12 for collection, completing the third oil extraction operation. The switching power element 425 is then activated to engage the third gear 426 and the third rack 427, opening the third discharge port 253 at the bottom of the processing container 2. This allows the completely discarded oil residue to fall from the bottom of the processing container 2 into the third collection box 13. The push-pull power element 422 is then reversed, sealing the third discharge port 253 at the bottom of the processing container 2. The device now achieves three consecutive oil extraction operations, enabling continuous and efficient oil extraction, and has significant technical benefits for extracting oil from large quantities of oil residue.

[0062] The technical scope of the present invention is not limited to the contents of the above description. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of ​​the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
