Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example: Figures 1-6 As shown, this utility model provides an oil-water separation device for measuring the oil content of oil wells, including a housing 1. An installation plate 2 is rotatably connected to one end of the housing 1. Coalescing filter cartridges 3 are rotatably connected to both ends of the installation plate 2. A first motor 4 is fixedly connected to one end of the top of the housing 1. A bidirectional lead screw 5 is fixedly connected to the output end of the first motor 4. A top cover 6 is threadedly connected to the bidirectional lead screw 5 above the installation plate 2. A receiving hopper 7 is threadedly connected to the bidirectional lead screw 5 below the installation plate 2. One end of the top cover 6 is fixedly connected to... U-shaped nozzle 8, with first brush plate 9 fixedly connected to both ends of U-shaped nozzle 8; connecting plate 10 fixedly connected to one end of receiving hopper 7; water spray pipe 11 fixedly connected to one end of connecting plate 10; second brush plate 12 fixedly connected to the other end of connecting plate 10; sliding rod 21 fixedly connected to the end of housing 1 away from bidirectional lead screw 5; top cover 6 and receiving hopper 7 are slidably connected to sliding rod 21; third motor 16 fixedly connected to one end of inner wall of housing 1; output end of third motor 16 fixedly connected to mounting plate 2.

[0028] In the embodiment, the two coalescing filter cartridges 3 are opposite in opening direction, wherein the opening of the coalescing filter cartridge 3 at one end of the top cover 6 is upward, and the opening of the coalescing filter cartridge 3 at the other end is downward, wherein the coalescing filter cartridge 3 uses a composite material such as glass fiber or polyester fiber, which has hydrophilic properties, and can not only filter out mechanical impurities in the medium, but also separate water in an emulsified state from the medium by demulsification and coalescence, and coalesce into larger water droplets. In the oil-water separation process, water cannot pass through the coalescing filter cartridge 3, and oil can pass through the coalescing filter cartridge 3 smoothly, thereby achieving the purpose of oil-water separation. In operation, the first motor 4 needs to be turned on to drive the bidirectional screw rod 5 to rotate, thereby driving the top cover 6 and the receiving hopper 7 to move synchronously and reversely. When the top cover 6 covers the opening of the coalescing filter cartridge 3, the receiving hopper 7 covers the lower end of the coalescing filter cartridge 3 at this time, so that the separated oil can fall into the receiving hopper 7. When the coalescing filter cartridge 3 is used for a long time, impurities will adhere to its surface, and at this time, the coalescing filter cartridge 3 needs to be cleaned. At this time, the first motor 4 is used to drive the top cover 6 and the receiving hopper 7 to move away from the mounting plate 2, and then the third motor 16 is turned on. Under the driving of the third motor 16, the mounting plate 2 rotates, thereby replacing the two coalescing filter cartridges 3. At this time, the opening of the replaced coalescing filter cartridge 3 is downward, thereby facilitating the subsequent discharge of waste water. The U-shaped spray pipe 8 and the first brush plate 9 are designed to clean the outer wall of the coalescing filter cartridge 3, and the water spray pipe 11 and the second brush plate 12 are designed to clean the inner wall of the coalescing filter cartridge 3.

[0032] In this embodiment, the cleaning liquid is delivered into the U-shaped spray pipe 8 by the design of the first water pump 17, so that the U-shaped spray pipe 8 can wash the outer wall of the coalescence filter cartridge 3. Since the mounting plate 2 needs a certain space when rotating, the U-shaped spray pipe 8 moves up and down with the top cover 6. Therefore, by the design of the first hose 18, the first water pump 17 can smoothly deliver the cleaning liquid into the U-shaped spray pipe 8 without affecting the up and down movement of the U-shaped spray pipe 8.

[0033] The second water pump 19 is fixedly connected to one end of the side wall of the box body 1, and the second water pump 19 is communicated with the second hose 20 at the output end. The second hose 20 is communicated with the water spray pipe 11.

[0034] In this embodiment, the cleaning liquid is delivered into the water spray pipe 11 by the design of the second water pump 19, so that the water spray pipe 11 can wash the inner wall of the coalescence filter cartridge 3. Since the mounting plate 2 needs a certain space when rotating, the water spray pipe 11 moves up and down with the top cover 6. Therefore, by the design of the second hose 20, the second water pump 19 can smoothly deliver the cleaning liquid into the water spray pipe 11 without affecting the up and down movement of the water spray pipe 11.

[0035] The feeding pipe 22 is fixedly connected to the middle of the top cover 6 and penetrates to the lower side of the top cover 6 at the bottom. The feeding pipe 22 is slidingly connected with the box body 1, and the feeding pipe 22 is communicated with the feeding hopper 23 at the top.

[0036] In this embodiment, when oil-water separation is performed, the oil-water mixture is first poured into the feeding hopper 23. At this time, the oil-water mixture flows into the coalescence filter cartridge 3 through the feeding pipe 22, so as to perform subsequent oil-water separation.

[0038] In this embodiment, after a period of oil-water separation operation, the separated water in the coalescence filter cartridge 3 needs to be drained. At this time, the third water pump 24 is opened. Under the action of the third water pump 24, the water in the coalescence filter cartridge 3 flows into the third hose 26 through the water suction pipe 25, and then flows into the first water drainage pipe 27 through the third hose 26, and is finally drained from the first water drainage pipe 27.

The design of the fourth hose 29 allows the hopper 7 to move up and down smoothly. The design of the second drain pipe 30 allows the wastewater generated during the cleaning of the coalescing cartridge 3 to be discharged smoothly. The design of the door body 31 allows the staff to maintain the inside of the box 1.
