[0040] The end of the separation sleeve 201 away from the driving motor 2 is fixedly connected with a backflow pipe 204, the backflow pipe 204 is sleeved outside the driving rod 203 and does not contact the outer surface of the driving rod 203, the end of the backflow pipe 204 away from the separation sleeve 201 is rotatably installed with a turbine blade 205, and the outer surface of the turbine blade 205 is fixedly welded with a stirring blade 206, the bottom end of the driving rod 203 is fixedly connected with the turbine blade 205, and the inner end of the turbine blade 205 is provided with a flow guide groove 207 capable of allowing gas to flow.

[0041] Embodiment 2: please refer to Figure 3 , Figure 4 As shown in, an oil-gas conveying pressurizing device based on the basis of embodiment 1, the left chamber of the separation sleeve 201 is provided with a liquid inlet 209, the liquid inlet 209 is in communication with the inside of the separation cartridge 1, and the right chamber of the separation sleeve 201 is provided with a gas outlet 208, and the gas outlet 208 is in communication with the backflow pipe 204, and the end of the separation cartridge 1 away from the driving motor 2 is fixedly welded with a conical hopper 202;

[0042] The oil-gas mixture liquid flows into the inside of the separation cylinder 1 through the liquid inlet pipe 3, and then the stirring blade 206 is driven to rotate by the turbine blade 205, and a rotating flow field is formed in the inside of the separation cylinder 1, so that the gas-liquid preliminary separation is realized. Due to the significant difference in density between the oil liquid and the gas, the forces generated by the oil liquid mixture on different phases during the centrifugal rotation are also different. The crude oil is quickly close to the inner wall of the separation cylinder 1 under the action of the centrifugal force, and flows along the inner wall of the separation cylinder 1 to the inside of the conical hopper 202, while the gas is concentrated near the central axis of the separation cylinder 1 and flows upward along the central axis, and finally passes through the inside of the turbine blade 205 and flows out from the gas outlet 208 along the reflux pipe 204.

[0043] The stirring blade 206 is twisted, which further enhances the rotating flow intensity and improves the gas-liquid separation efficiency when the turbine blade 205 rotates.

[0044] As shown in Figures 5-7 , the inner end of the isolation cylinder 402 is rotatably installed with a sealing pipe 302, the upper end of the sealing pipe 302 is fixedly welded with a passive ring 401, the passive ring 401 is arranged in the inside of the conical hopper 202, the crude oil forms a vortex motion under the rotation of the turbine blade 205, so as to drive the passive ring 401 to rotate, the outer surface of the sealing pipe 302 is fixedly installed with two oil crushing shells 404, the two oil crushing shells 404 are located in the inside of the isolation cylinder 402, and the two oil crushing shells 404 correspond to the two deslagging pipes 301 respectively, the inner end of the isolation cylinder 402 is fixedly installed with a flow guide ring 405, and the flow guide ring 405 is sleeved on the outer surface of the sealing pipe 302.

[0045] A plurality of rectangular holes are formed in the outer surface of the flow guide ring 405, the rectangular holes are arranged in a ring shape, and the inner end of each rectangular hole is rotatably installed with a stirring block 406 through a rotating shaft, specifically, the outer surface of the stirring block 406 is fixedly welded with a protrusion, a plurality of rectangular slot holes are formed in the outer surface of the passive ring 401, the rectangular slot holes are communicated with the upper chamber of the flow guide ring 405, and the impurities in the crude oil enter the upper part of the flow guide ring 405 through the rectangular slot holes. It is worth noting that the aperture of the rectangular slot hole is larger than the volume of any impurity in the crude oil, so that the phenomenon of blockage does not occur during the working process.

[0046] When the impurities move to the upper part of the flow guide ring 405, the rotating passive ring 401 drives the impurities to move through the crude oil, the impurities are in contact and friction with the protrusions on the surface of the stirring block 406, and are gradually broken and reduced in size, while driving the stirring block 406 to rotate, and finally flowing to the lower part of the flow guide ring 405 along with the crude oil.

[0047] As shown in Figure 5 , Figure 7 , Figure 8As shown, in order to optimize the movement fluency of the oil crushing shell 404, the inner bottom end of the sealing pipe 302 is fixedly installed with a rotating ring 408, and the upper end of the rotating ring 408 is welded with a passive impeller 407. When the crude oil forms a vortex flow, the passive impeller 407 is driven to rotate, thereby enhancing the movement force of the oil crushing shell 404. The inner end of the oil crushing shell 404 is provided with a rotating rod 413, and the upper and lower ends of the rotating rod 413 are both fixedly connected with special-shaped blocks 412.

The rectangular holes are all provided with knocking blocks 409, and the outer surface of the knocking block 409 is rotatably installed with a passive plate 410. The passive plate 410 is located inside the oil crushing shell 404. Specifically, the passive plate 410 corresponds to the special-shaped block 412. When the special-shaped block 412 rotates, the outer surface protruding part contacts the outer surface of the passive plate 410, and the passive plate 410 pushes the knocking block 409 to move away from the oil crushing shell 404.

[0048] More specifically, the passive plate 410 and the oil crushing shell 404 are connected through the reset spring 411, so that after moving, the passive plate 410 restores to the initial state under the elastic force of the reset spring 411. It should be noted that the outer surface of the oil crushing shell 404 does not contact the inner wall of the isolation cylinder 402, so the knocking block 409 can move towards the outside of the oil crushing shell 404. When the oil crushing shell 404 rotates outside the sealing pipe 302, the knocking block 409 also reciprocates constantly, thereby further crushing the impurities in the crude oil and preventing pipeline blockage in subsequent flow.

[0049] The inner bottom end of the support cylinder 5 is fixedly connected with an oil seepage pipe 403, and a plurality of oil seepage holes are uniformly formed in the outer surface of the oil seepage pipe 403.

[0051] Specifically, the inner end of the center pipe 303 is provided with a threaded rod 309, the outer surface of the threaded rod 309 is threadedly sleeved with a movable plug 306, the outer surface of the movable plug 306 is tightly combined with the inner wall of the center pipe 303, the outer surface of the movable plug 306 is provided with a rectangular slot, and the inner end of the center pipe 303 is fixedly installed with a rectangular strip, which is provided in the rectangular slot, so that the movable plug 306 does not rotate when it is moved by the rotation of the threaded rod 309, and the center pipe 303 is communicated with the sealing capsule 308 through a through pipe.

[0052] The end of the center pipe 303 away from the guide plates 307 is rotatably connected with a center rod 304, the center rod 304 is fixedly connected with the threaded rod 309, the inner side of the filter cartridge 101 is provided with an unlocking rod 305, and the end of the unlocking rod 305 away from the slag discharge pipe 301 is fixedly connected with a rotating handle through a bolt, so that the staff can more conveniently rotate the unlocking rod 305, and it is particularly noted that a cut-off valve is arranged at the connection between the oil outlet pipe 4 and the filter cartridge 101, the valve can be closed before the filter cartridge 101 is disassembled, the pipeline communication is effectively blocked, and the leakage risk of residual crude oil in the oil outlet pipe 4 is completely prevented.

[0053] The adjacent ends of the unlocking rod 305 and the center rod 304 are fixedly connected with a primary-secondary clamping block, and the two sets of clamping blocks are engaged with each other, the unlocking rod 305 is driven to rotate through the engagement of the clamping blocks, and the center rod 304 is directly driven to rotate synchronously, and the connection mode is not limited to the primary-secondary clamping block, but can also be a ratchet engagement device.

[0054] The working principle of the application is as follows:

[0055] In use, the oil-gas mixture comes to the inside of the separation cylinder 1 through the liquid inlet pipe 3, the output end of the driving motor 2 drives the driving rod 203 to rotate, the driving rod 203 drives the turbine blade 205 to rotate at the same time, so that the oil-gas mixture swirls in the separation cylinder 1, the gas part passes through the inside of the turbine blade 205, and flows along the inside of the return pipe 204, and then flows out from the gas outlet 208, and then the gas flows into the gas outlet pipe 6, and then the gas outlet pipe 6 delivers the gas to the next device;

[0056] The swirling flow of the crude oil drives the passive ring 401 and the sealing pipe 302 to rotate, and at the same time, the pressure of the crude oil is increased under the action of the turbine blade 205, so that the impurities in the crude oil enter above the flow guide ring 405 through the rectangular slot of the passive ring 401, and under the action of the swirling flow of the crude oil, the impurities move above the flow guide ring 405, and gradually become smaller after rubbing the outer surface of the crushing block 406, and then flow below the flow guide ring 405, at this time, the oil crushing shell 404 rotates under the action of the passive gear 414 meshing with the gear ring 415, drives the rotating rod 413 to rotate, the rotating rod 413 drives the passive plate 410 to move through the special-shaped block 412, so that the knocking block 409 moves, and then the knocking block 409 restores to the initial state under the elastic force of the return spring 411, to further crush the impurities in the crude oil in the isolation cylinder 402, to avoid blocking the pipeline during flow;

[0057] Then the crude oil flows into the oil outlet pipe 4 through the oil permeation pipe 403, because the crude oil in the oil outlet pipe 4 is constantly flowing, the crude oil containing impurities in the filter cylinder 101 flows into the oil outlet pipe 4 again after being filtered;

[0058] When the impurities in one of the filter cylinders 101 accumulate too much, the unlocking rod 305 is driven to rotate by rotating the handle, the unlocking rod 305 drives the center rod 304 to rotate, at this time, the center rod 304 drives the movable plug 306 to move through the threaded rod 309 when rotating, the movable plug 306 compresses the air in the center pipe 303 when moving, so that the sealing bag 308 expands, and then the outer surface of the sealing bag 308 contacts with the inner wall of the sealing pipe 302 after expanding, so as to realize the flow of the liquid in the slag discharge pipe 301 is cut off, then the valve of the filter cylinder 101 and the oil outlet pipe 4 is gradually closed, then the fixing bolts between the filter cylinder 101, the slag discharge pipe 301 and the oil outlet pipe 4 are removed, and the filter cylinder 101 is replaced, at this time, the unlocking rod 305 engages with the center rod 304, so as to realize the replacement of the filter equipment without stopping the machine, and ensure the continuous mining operation.
