Description

Technical Field

[0001] The 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. In the process of oil extraction, 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 discloses an oil extraction device for petroleum residue, comprising 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 and cannot clean impurities in the pipeline, which affects the subsequent discharge of oil.

[0053] A sealing portion 4121 is protruded from the bottom surface of the sealing plate 412 .

[0054] Electric valves are installed on the first pipeline 231, the second pipeline 241, the third pipeline 251 and the water inlet pipe 252 for automatically controlling the circulation of the pipelines. The connection between the first pipeline 231 and the processing container 2 is located at the lowest point of the crushing chamber 23, the connection between the second pipeline 241 and the processing container 2 is located at the lowest point of the extrusion chamber 24, and the connection between the third pipeline 251 and the processing container 2 is located at the lowest point of the mixing chamber 25.

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

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

[0057] The device also includes 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 petroleum residue from the outside is allowed to enter the feed funnel 14, and 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 started to crush the petroleum residue in the crushing chamber 23, and the oil enters the first collection box 11 along the first pipe 231. The filter plate 26 in the first pipe 231 blocks the petroleum residue, and the oil in the crushed petroleum residue is more likely to fall from the first pipe 231 into the first collection box 11, and the first oil extraction operation is performed at this time;

[0059] After the crushing is completed, the switching power member 425 is started to mesh the third gear 426 and the first third rack 427, and the push-pull power member 422 is started 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, so that the sealing plate 412 rotates downward, and the rotating shaft 413 rotates, and the rotating shaft 413 drives the first gear 414 to rotate, and 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, so that the second rack 417 moves upward, so that the cleaning head 418 rises to 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 pushed and pulled in reverse, so that the sealing plate 412 blocks 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 pipeline 9 .

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

[0061] Then start the switching power member 425 so that the third gear 426 and the second third rack 427 are meshed. At this time, continue to start the driving member 3 so that the extrusion mechanism 32 squeezes the oil residue in the extrusion chamber, and the extruded oil falls from the second pipe 241 into the first collection box 11 for collection. At this time, the second oil extraction is completed. After the extrusion is completed, close the driving member 3. At this time, the mechanism on the first baffle 21 will not move. At this time, start the push-pull power member 422 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, so that the sealing plate 412 rotates downward, so that the second discharge port 242 on the second baffle 22 is opened to send the extruded oil into the mixing chamber 25. At this time, the external water supply pipe 252 is passed with clean water, and the oil residue entering the mixing chamber 25 is mixed with the clean water. Then reverse the push-pull power member 422 to close the second discharge port 242 on the second baffle 18, and then allow the petroleum residue in the crushing chamber to fall into the extrusion chamber for operation. After the petroleum residue and clean water in the mixing chamber are mixed, the electric valve on the third pipeline 251 is opened to allow the mixture of petroleum and clean water to enter the second collection box 12 for collection, completing the third petroleum extraction operation. Then start the switching power member 425 to make the third gear 426 and the third third rack 427 mesh, so that the third discharge port 253 at the bottom of the processing container 2 is opened, so that the completely discarded petroleum residue falls from the bottom of the processing container 2 into the third collection box 13, and then reverse the push-pull power member 422 to block the third discharge port 253 at the bottom of the processing container 2. At this time, the device realizes three consecutive petroleum extraction operations, so that the device can continuously and efficiently extract petroleum, which has a significant technical effect on extracting petroleum from large quantities of petroleum residues.

[0062] The technical scope of the present invention is not limited to the contents in 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.
