Working principle: introducing oilfield sewage into the treatment tank 1, injecting flocculant into the treatment tank 1 through the flocculant adding pipe 2, then generating gas-dissolved water by using the air floatation mechanism, so that crude oil and suspended matters in the sewage float up to the water surface, then controlling the driving roller 7 and the driving belt 8 to rotate through a motor, driving the plurality of oil scraping hoppers 9 to move on the water surface, and further enabling the crude oil and suspended matters to enter the oil scraping hoppers 9, scraping the crude oil and suspended matters into the filter tank 3 through the oil scraping hoppers 9, and then filtering, so that crude oil can be obtained from the oilfield sewage, and the efficiency of scraping the crude oil can be improved and the working time can be saved by arranging the oil scraping hoppers 9 relative to a flat plate structure of a scraper; by arranging the oil scraping bucket 9 to be movable, when the device is designed and produced, the distance between the oil scraping bucket 9 and the transmission belt 8 is properly prolonged according to the preset water surface height in the treatment tank 1 (by designing the lengths of the guide plate 10 and the spring 12), so that the oil scraping bucket 9 can extend into the water surface after rotating to the lower side, the efficiency of entering crude oil and suspended matters into the oil scraping bucket 9 is improved, crude oil on the water surface is fully scraped, and when the oil scraping bucket 9 moves to the inclined plate 5, the inclined surface at the bottom of the oil scraping bucket 9 is mutually extruded with the inclined plate 5, so that the sliding block 11 is promoted to slide upwards, and the oil scraping bucket 9 can smoothly cross the inclined plate 5 without interference with the inclined plate 5; by arranging the elastic pad 14 and the oil scraping bucket 9 to be sealed with each other, crude oil and suspended matters can enter the surface of the elastic pad 14 in the oil scraping bucket 9, when the oil scraping bucket 9 moves to the position above the inclined plate 5, the magnetic plate 13 generates repulsive force to the movable rod 15, the repulsive force is larger than the tension force of the elastic rope 16, and the movable rod 15 is pushed to move upwards to drive the elastic pad 14 to turn outwards, so that the crude oil and suspended matters in the elastic pad 14 are ejected out, and the efficiency of discharging the crude oil into the filter tank 3 is improved; by arranging the pair of guide strips 17, the movement of the movable rod 15 can be guided and limited, so that the movable rod 15 is always positioned in the middle of the oil scraping bucket 9, and the ejection efficiency of crude oil and suspended matters is improved; by setting the inclined direction of the guide bar 17, the movable rod 15 can move towards the opening direction of the oil scraping hopper 9 under the repulsive force of the magnetic plate 13, so that crude oil and suspended matters in the elastic pad 14 are fully ejected, and the ejection efficiency is further improved; when the oil scraping hopper 9 moves above the driving belt 8, residual crude oil on the surfaces of the oil scraping hopper 9 and the elastic pad 14 can drop downwards to the surface of the driving belt 8 and is converged into the filter tank 3 again along the inclined surface of the driving belt 8, so that the collection efficiency of the crude oil is improved, and the two sides of the driving belt 8 are blocked by arranging the isolating strips 18 to prevent the crude oil from flowing away from the two sides of the driving belt 8; in the process of rotating the driving roller 7, the pressing plate 22 on the surface of the driving roller can intermittently extrude the air storage block 20 to extrude and deform the air storage block 20, and air in the air storage block is outwards sprayed out through the air pipe 21, so that oil on the top surface of the driving belt 8 is downwards pushed by the air flow, the collection efficiency of crude oil is further improved, and when the pressing plate 22 does not extrude the air storage block 20 any more, the air storage block 20 automatically expands and recovers and sucks air again through the air pipe 21; by arranging the shapes of the air storage block 20 and the pressure plate 22, the pressure plate 22 and the air storage block 20 can be smoother when being mutually extruded, the resistance during extrusion is reduced, the abrasion between the two is reduced, and by arranging the guide plate 10 to be a rigid grid material, oil can permeate the guide plate 10 when flowing on the surface of the transmission belt 8, and the blocking of the oil flowing is reduced; by arranging the conical blocks 23, the air flow can be dispersed by the conical blocks 23 when the air pipe 21 sprays air, and part of the air flow flows through the flow dividing holes 25, so that the dispersion degree of the air flow is improved, the action area of the air flow is increased, and the oil on the surface of the transmission belt 8 is further pushed downwards, so that the oil is fully converged into the filter tank 3; in the process that the oil scraping bucket 9 gradually approaches the inclined plate 5, the repulsive force of the magnetic plate 13 to the movable rod 15 is increased from small, the movable rod 15 drives the ball 27 to move upwards through the connecting strip 26, the ball 27 is blocked by the pair of hook blocks 29, so that the movable rod 15 stores force, when the oil scraping bucket 9 moves to the position above the magnetic plate 13, the repulsive force of the magnetic plate 13 to the movable rod 15 is maximum, the ball 27 is further promoted to squeeze and deform the hook blocks 29 and pass over the hook blocks 29, at the moment, the movable rod 15 obtains a larger instant speed and drives the elastic pad 14 to bounce outwards, crude oil and suspended matters in the elastic pad 14 are further ejected, the efficiency of discharging crude oil outwards can be improved, the residue of the crude oil on the surface of the elastic pad 14 is reduced, after the subsequent oil scraping bucket 9 is far away from the magnetic plate 13, the movable rod 15 is pulled to reset by the elastic rope 16, the ball 27 is driven to squeeze the hook blocks 29 and return to the position between the pair of supporting pieces 28, and returning is achieved.
