Referring to fig. 1-3, in the embodiment of the present invention, an oil-water separation device comprises a separation kettle 1, an oil collection kettle 2 and a carbon sponge 3, wherein the upper end inside the separation kettle 1 is rotatably connected with a pull roll 10 through a rotating shaft 15, the pull roll 10 is provided with two pull rolls and horizontally arranged in the separation kettle 1, a gear 17 is fixedly connected to the rotating shaft 15 on one side of the two pull rolls 10 and the two gears are meshed with each other, a water inlet 4 is arranged on the separation kettle 1, a ball float valve 6 is arranged at one end of the water inlet 4 positioned inside the separation kettle 1, a water outlet 5 is arranged at the lower end of the separation kettle 1, the oil collection kettle 2 is arranged at the left side of the separation kettle 1, an oil squeezing roll group 9 is rotatably connected inside the oil collection kettle 2 through the rotating shaft 15, the carbon sponge 3 is rotatably connected between the two pull rolls 10, the carbon sponge 3 is rotatably connected between the oil squeezing roll group 9, the carbon sponge 3 is in transmission connection, a roller 16 is arranged in the separation kettle 1, and the roller 16 is positioned below the pull roller 10 and is level with the ball float valve 6.

Wherein, crowded oily roller set 9 comprises roller 11 and lower roll 12 in the multiunit, go up roller 11 and lower roll 12 and closely laminate in one, the dislocation is come about in every group of crowded oily roller set 9 roller 11 and lower roll 12, roll connection carbon sponge 3 between roller 11 and the lower roll 12 in every group, rotate through hold-in range 13 between the lower roll 12 of crowded oily roller set 9 every group and connect, the outside fixedly connected with motor 8 of collection oil cauldron 2, one of them and lower roll 12 fixed connection of crowded oily roller set 9 are on the output shaft of motor 8. The oil adsorbed in the carbon sponge 3 can be extruded out and falls into the oil collecting kettle 2 for collection; the output shaft of the motor 8 is rotationally connected with the right one of the two pull rollers 10 through a second synchronous belt 14. The whole device is driven by a motor to move synchronously; the inner wall of the separation kettle 1 is fixedly connected with a buffer plate 18, and the buffer plate 18 is positioned right below the water outlet position of the water inlet 4. When water enters the device, water flow splashes water so that oil and water are mixed again; an oil outlet 7 is arranged on the oil collecting kettle 2. For discharging oil; the carbon sponge 3 is graphene-composed aerogel. The carbon sponge can be adjusted in shape at will, has good elasticity, and can be restored to the original shape after being compressed by 80%. It has super-fast and super-high adsorption force to organic solvent, the existing oil-absorbing product can only absorb about 10 times of liquid by its own mass, and the carbon sponge can absorb about 250 times, up to 900 times, and only absorbs oil but does not absorb water.

The utility model discloses a theory of operation is: the water inlet 4 discharges the oil-water mixed water into the separation kettle 1, and the oil and the water can be automatically layered.
