In this embodiment, the lower floating block 238 is an inverted cup-shaped structure for preventing the influence of the density change of the mixed oil.
The working process is as follows: in the initial state, the first stirring block 255, the second stirring block 256 and the third stirring block 257 are in the first spiral groove, and the first gear ring and the second gear ring are disengaged from the reversing gear 254.
The oil-water separation device is started by the controller 14, and the mixed liquid firstly passes through the filter screen 13. The oil-water impurities are filtered, the impurities with larger diameters are intercepted by the filter screen, the more-heavy impurities are intercepted by the partition plate 12, the water-oil mixture flows into the lifting system part through the upper layer of the partition plate 12, and then the insoluble impurities are deposited in water through sedimentation, so that oil and water are layered. The double-helix screw rod 22 is driven by an external motor to rotate anticlockwise, and as the inner end of the first stirring block 255 is inserted into the first spiral groove and the outer end is inserted into the insertion groove, the double-helix screw rod 22 rotates to push the upper sliding ring 251 to move upwards and drive the support plate 23 to move upwards on the guide rod 21. At the moment, the upper buoyancy block is arranged at the junction of the oil phase and the air, and the lower buoyancy block is arranged above the junction of the water phase and the oil phase. The supporting plate 23 continues to rise, the upper floating block 235 gradually floats out of the oil surface along with the rising of the supporting plate 23, at the moment, when the upper floating block 235 goes out of the oil layer, the buoyancy of the oil layer on the upper floating block 235 is reduced, the upper floating block moves downwards under the action of gravity, the one-way sliding rod 236 is driven to move downwards and press the upper pressure shaft 237 to move downwards, the upper pressure shaft 237 presses the upper pressure rod 233 to move downwards, the connecting rod 232 connected with the upper pressure rod 233 drives the sliding shaft 231 to slide towards the direction far away from the double-helix screw rod 22, the connecting rod 232 connected with the lower pressure rod 233 drives the lower pressure rod 233 to move upwards, finally, the upper pressure rod 233 extrudes the upper sliding ring 251, and the upper pressure rod 233 extrudes the lower sliding ring 253.

At this time, the first stirring block 255 and the third stirring block 257 exit from the first spiral groove, the upper pressing rod 233 continues to press the upper sliding ring 251, the upper pressing rod 233 continues to press the lower sliding ring 253, the gap between the upper sliding ring 251 and the lower sliding ring 253 gradually disappears, the first gear ring and the second gear ring are meshed with the reversing gear 254, the second stirring block 256 is pushed by the first spiral groove to rotate the sliding ring 252, the upper sliding ring 251 does not rotate, the middle sliding ring 252 rotates, the lower sliding ring 253 rotates relative to the upper sliding ring 251, and at this time, the rotation direction formed by the first stirring block 255, the second stirring block 256 and the third stirring block 257 is the same as the rotation direction of the first spiral groove in an initial state and is converted into the same as the rotation direction of the second spiral groove. The double-spiral lead screw 22 still rotates anticlockwise, at this time, the rotation directions formed by the first stirring block 255, the second stirring block 256 and the third stirring block 257 are changed, the first stirring block 255 and the third stirring block 257 enter the second spiral groove under the action of the spring, and at this time, the double-spiral lead screw 22 rotates anticlockwise to enable the support plate 23 to move downwards.
The upper floating block 235 is moved upward by buoyancy in the oil layer, and the one-way sliding rod 236 is moved upward with respect to the rotating plate 241. The support plate 23 descends and the lower float 238 sinks into the water layer, and since the density of the lower float 238 is lower than that of water, the buoyancy becomes larger after entering the water layer, and the lower float moves upward under the action of the buoyancy. The supporting rod moves upwards, the pressing pressure shaft 237 moves upwards, the upper pressing rod 233 finally presses the upper sliding ring 251, the upper pressing rod 233 presses the lower sliding ring 253 through the pressing assembly, the second stirring block 256 moves to the intersection of the first spiral groove and the second spiral groove of the double-spiral screw rod 22, the first stirring block 255 is in contact with the outer end of one third top block 222, and the third stirring block 257 is in contact with the outer end of the other third top block 222. The first and third tiles 255 and 257 are compressed. At this time, the first stirring block 255 and the third stirring block 257 exit from the second spiral groove, the upper pressing rod 233 continues to press the upper sliding ring 251, the upper pressing rod 233 continues to press the lower sliding ring 253, the gap between the upper sliding ring 251 and the lower sliding ring 253 disappears, the first gear ring and the second gear ring are meshed with the reversing gear 254, the second stirring block 256 is pushed by the first spiral groove to rotate the middle sliding ring 252, the upper sliding ring 251 does not rotate, the middle sliding ring 252 rotates, the lower sliding ring 253 rotates relative to the upper sliding ring 251, and at this time, the rotation direction formed by the first stirring block 255, the second stirring block 256 and the third stirring block 257 is the same as the rotation direction of the second spiral groove from the initial state and is converted into the same as the rotation direction of the first spiral groove. The double-spiral screw rod 22 still rotates anticlockwise, at this time, the turning direction formed by the first stirring block 255, the second stirring block 256 and the third stirring block 257 is changed, the first stirring block 255 and the third stirring block 257 enter the first spiral groove under the action of the spring, and at this time, the double-spiral screw rod 22 rotates anticlockwise to enable the support plate 23 to move upwards.
When the thickness of the oil layer is reduced, since the ratchet plate is disposed on the circumferential wall of the one-way sliding rod 236, the pawl is installed at the upper end of the rotating plate 241, and the pawl is caught in the ratchet groove of the ratchet plate in an initial state. The upper floating block 235 is positioned in the oil layer due to the fact that the one-way sliding rod 236 is clamped in the rotating plate 241, and when the upper floating block 235 is about to go out of the oil layer, the buoyancy of the oil layer on the upper floating block 235 is reduced, and the upper floating block moves downwards under the action of gravity. The lower floating block 238 is of an inverted cup-shaped structure and is positioned in an oil layer, and when entering a water layer, as the density of the lower floating block 238 is smaller than that of water, the buoyancy is increased after entering the water layer, and the lower floating block moves upwards under the action of the buoyancy.
