The choking unit is used to divert and reduce the pressure of the solution inside multiple pipes; Screening unit; the screening unit includes a chassis 321 fixedly arranged at one end of the first diversion pipe 32. A cylinder 34 is rotatably arranged on the chassis 321. A connecting shaft 341 is slidably arranged inside the cylinder 34. A filter plate 9 is rotatably arranged on the connecting shaft 341. A first discharge pipe 5 is fixedly arranged on the outer circumferential surface of the first diversion pipe 32. The screening unit is used to filter the particulate impurities mixed in the solution of the first diversion pipe 32; Referring to Figures 1-3 , four mutually parallel support columns 11 are fixedly arranged on the bottom plate 1, and each support column 11 is evenly arranged at each corner of the bottom plate 1. An anti-slip plate 12 is fixedly arranged at the end of the support column 11. By arranging the support columns 11 on the bottom plate 1, the overall support function of the device is realized. At the same time, by arranging each support column 11 at the corner of the bottom plate 1, each support column 11 can be evenly stressed during the support process of the device, avoiding the situation that the support column 11 is damaged due to uneven stress during the support process. At the same time, the anti-slip plate 12 arranged at the bottom end of the support column 11 can increase the friction between the device and the ground, avoiding the situation that the device slips during use.

[0022] Referring to Figures 1-3 , bolts 311 are fixedly arranged between two adjacent flanges 31, and the bolts 311 are evenly distributed. By arranging the bolts 311 between the two flanges 31, two different flanges 31 are connected, and a sealing ring is added at the connection of the two flanges 31 to ensure the airtightness of the whole device, avoiding the effect of petroleum spilling during the use of the device, and improving the safety of the device.

[0023] Referring to Figures 3-5, a handwheel 42 is fixedly arranged at the end of each regulating pipe 41 and the first shunt pipe 32, and an anti-slip sleeve is sleeved on the outer peripheral surface of the handwheel 42. The handwheels 42 arranged on the regulating pipe 41 and the first shunt pipe 32 are used to regulate the flow rate of the petroleum in the device, ensuring that the petroleum in the pipeline can be adjusted by the staff in real time.

[0024] Refer to Figures 2-4 , a collector 6 is fixedly arranged on the bottom plate 1. The collector 6 is communicated with the output ends of the first shunt pipe 32 and the second shunt pipe 4. A second discharge pipe 7 for discharging the solution is arranged on the collector 6. Through the collector 6 arranged on the bottom plate 1, the petroleum in the first shunt pipe 32 and the second shunt pipe 4 can be collected and processed, and the processed petroleum is discharged from the second discharge pipe 7 of the device and collected and stored by the staff, which is simple and convenient.

[0025] Refer to Figures 3-5 , a connecting column 33 is fixedly arranged at one end of the chassis 321. The connecting column 33 is fixedly connected with the handwheel 42. A pressing plate 3413 is fixedly arranged at one end of the connecting shaft 341. The pressing plate 3413 is slidably connected with the cylinder 34. A spring 340 is fixedly arranged between the pressing plate 3413 and the bottom end of the cylinder 34. Through the connecting column 33 arranged on the chassis 321, when the connecting shaft 341 slides, the moving connecting shaft 341 can drive the pressing plate 3413 to move and compress the spring 340, and the elastic force generated by the spring 340 can clamp the connecting shaft 341 at a fixed position when the device is idle.

[0026] Refer to Figures 5-7 , a fan blade 342 is fixedly arranged on the outer peripheral surface of the connecting shaft 341. A plurality of filter holes 91 are arranged on the filter plate 9, and the plurality of filter holes 91 are evenly distributed. The filter plate 9 is slidably connected with the inner wall of the first shunt pipe 32. Three uniformly arranged connecting plates 3411 are fixedly arranged on the outer peripheral surface of the connecting shaft 341, and the connecting plates 3411 are mutually attached to the outer surface of the filter plate 9. A scraping plate 92 is fixedly arranged on the connecting plate 3411, and the scraping plate 92 is mutually attached to the inner wall of the first shunt pipe 32. Through the fan blade 342 arranged on the outer peripheral surface of the connecting shaft 341, it is realized that the petroleum flowing in the first shunt pipe 32 can drive the fan blade 342 to rotate, the rotating fan blade 342 can drive the connecting shaft 341 to rotate. At this time, the connecting shaft 341 drives the scraping plate 92 to rotate through the connecting plate 3411, and the connecting plate 3411 can scrape off the particulate impurities attached to the outer surface of the filter plate 9 during the rotation process, ensuring the normal flow of the petroleum in the first shunt pipe 32.

[0027] Refer to Figures 5-7, the three scraping plates 92 are all arranged in a spiral shape, and the cross-section of the connecting plate 3411 is inclined. By arranging the scraping plate 92 in a spiral shape, it is realized that the scraping plate 92 can push the particulate impurities in the first shunt pipe 32 during rotation.

[0028] Refer to Figures 4-6 , a discharge groove 35 is formed in the first shunt pipe 32. A sliding plate 352 is slidably arranged in the discharge groove 35. An adjusting plate 353 is fixedly arranged on the sliding plate 352. A sliding groove 351 matching the adjusting plate 353 is formed in the first shunt pipe 32. The filter plate 9 abuts against the adjusting plate 353. By arranging the discharge groove 35 on the first shunt pipe 32, it is realized that the particulate impurities accumulated on the filter plate 9 gradually seal the filter plate 9 during the operation of the device. At this time, the pressure of the petroleum increases and the filter plate 9 moves. At this time, the moving filter plate 9 drives the sliding plate 352 to move. At this time, the discharge groove 35 is in an open state, and the particles scraped under the push of the scraping plate 92 can be concentrated in the discharge groove 35.

[0029] Refer to Figures 6-8 , a storage box 8 is fixedly arranged on the outer peripheral surface of the first shunt pipe 32. A rotating shaft 81 is rotatably arranged in the storage box 8. A baffle 82 is fixedly arranged on the rotating shaft 81. The baffle 82 divides the storage box 8 into a first chamber 83 and a second chamber 84. By arranging the storage box 8 on the outer peripheral surface of the first shunt pipe 32, it is realized that the materials discharged from the discharge groove 35 are stored in the first chamber 83. When the petroleum in the first shunt pipe 32 flows normally, the sliding plate 352 returns to its original position under the thrust of the elastic metal. At this time, by controlling the rotation of the rotating shaft 81, the baffle 82 is driven to rotate to convey the particles in the first chamber 83 to the second chamber 84, thereby completing the discharge treatment of the impurities in the first shunt pipe 32.

[0030] The specific solution of this scheme is as follows: When the staff uses the device, they first move the device to a suitable position. The support columns 11 provided on the bottom plate 1 realize the support function for the device body. The various pipelines are connected to each other through the flanges 31 to ensure the airtightness of the overall device, avoid the effect of oil spillage during the use of the device, and improve the safety of the device. The connecting columns 33 provided on the chassis 321 enable the moving connecting shaft 341 to drive the pressing plate 3413 to move and compress the spring 340 when the connecting shaft 341 slides. The elastic force generated by the spring 340 can clamp the connecting shaft 341 to be in a fixed position when the device is idle. The fan blades 342 provided on the outer peripheral surface of the connecting shaft 341 enable the oil flowing in the first shunt pipe 32 to drive the fan blades 342 to rotate. The rotating fan blades 342 can drive the connecting shaft 341 to rotate. At this time, the connecting shaft 341 drives the scraper 92 to rotate through the connecting plate 3411. The connecting plate 3411 can scrape off the particulate impurities attached to the outer surface of the filter plate 9 during the rotation process to ensure the normal flow of the oil in the first shunt pipe 32. During the operation of the device, the particulate impurities accumulated on the filter plate 9 gradually seal the filter plate 9. At this time, the pressure of the oil increases and the filter plate 9 moves. At this time, the moving filter plate 9 drives the sliding plate 352 to move. At this time, the discharge groove 35 is in an open state, and the particulate matter scraped out under the push of the scraper 92 can be concentrated in the discharge groove 35. When the oil in the first shunt pipe 32 flows normally, the sliding plate 352 returns to its original position under the thrust of the elastic metal. At this time, the control rotating shaft 81 rotates to drive the baffle 82 to rotate, and the particulate matter in the first chamber 83 is conveyed to the second chamber 84, thereby completing the discharge treatment of the impurities in the first shunt pipe 32.
