[0002] Super-hydrophobic is a new material that can clean the place that needs to be clean by itself, and can also be placed on the metal surface to prevent corrosion from the outside world. Super-hydrophobic oleophilic material is often used to separate oil and water because of its hydrophobic and oleophilic characteristics. The super-hydrophobic oleophilic film in the oil-water separation device used in the current market is mostly fixedly connected to the device, and disassembly and replacement are more troublesome. The invention patent with the authorization announcement number CN105001443B discloses a polyurethane sponge of expanded graphite and zinc oxide composite modification and its preparation method. It is characterized in that the polyurethane sponge is composite-modified by expanded graphite and zinc oxide, and a uniform and dense coating is formed on the surface of the polyurethane sponge, so that the sponge obtains very strong hydrophobic oleophilicity (with a water contact angle of 149 °) after modification. The mass ratio of expanded graphite and zinc oxide of the present invention is 28:1, and its composite coating thickness is 0.6~0.9mm. The sponge prepared by the present invention can selectively adsorb oil in water quickly, and can be recycled, without secondary pollution, and provides a kind of efficient and environmentally friendly adsorption material for the processing of oil-contaminated water bodies.

[0032] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present invention.

[0033] Example 1:

[0034] like Figure 1—5 shows: an oil-water separation device based on super-hydrophobic material, comprising a main body 1, a water collecting tank 3 and an oil drain valve 6 are respectively provided at the upper and lower ends of the main body 1, the bottom side of the main body 1 is connected to a drain pipe 2, the bottom of the water collecting tank 3 is connected to an oil drain pipe 4, an interception valve 5 is installed on the oil drain pipe 4, a screw 10 is provided inside the water collecting tank 3, a fixing frame 7 is fixed on the screw 10 by a nut, the fixing frame 7 is slidably sleeved on the outside of the mounting frame 8, a plug-in slot 72 is provided on the fixing frame 7, the mounting frame 8 includes a connecting rod 81, and the side of the connecting rod 81 is provided with an adaptor plug-in connector. The positioning block 82 of the groove 72 is provided, and the bottom end of the connecting rod 81 is provided with a base frame 83. The outer side of the connecting rod 81 is provided with a modified polyurethane sponge 9. The detachable fixing frame 7 and the mounting frame 8 provide rigid support for the modified polyurethane sponge 9, so that the modified polyurethane sponge 9 can be conveniently and labor-savingly loaded and unloaded in the main body 1; by pulling the mounting frame 8, the modified polyurethane sponge 9 installed between the base frame 83 and the fixing frame 7 can be squeezed, thereby quickly discharging the oil collected in the pores of the modified polyurethane sponge 9. The fixing frame 7 and the base frame 83 are both hollow plate structures, and the water can flow smoothly through the hollow grooves on the fixing frame 7 and the base frame 83. The modified polyurethane sponge 9 is tightly packed with the main body 1 and the connecting rod 81, and the modified polyurethane sponge 9 can be tightly packed with the inside of the main body 1, effectively filtering the water entering the main body 1. The base frame 83 is threadedly connected to the connecting rod 81, and the operator can separate the base frame 83 from the connecting rod 81, so as to quickly and easily fit the modified polyurethane sponge 9 on the connecting rod 81. The number of the positioning blocks 82 is two, and they are arranged at a relative interval up and down. The two positioning blocks 82 facing each other are slidably connected to the upper and lower end faces of the fixing frame 7. When the positioning blocks 82 and the plug slots 72 are staggered, the fixing frame 7 , the relative distance between the base frame 83 is locked, the modified polyurethane sponge 9 can be quickly installed in the main body 1 under rigid support, when the positioning block 82 is relative to the plug-in slot 72, the connecting rod 81 can slide smoothly in the fixing frame 7, so that the modified polyurethane sponge 9 is squeezed by the base frame 83 and the fixing frame 7, and a pull ring 84 is provided on the top of the connecting rod 81. The operator can pull the pull ring 84 to conveniently rotate or pull the connecting rod 81, and the bottom end of the oil drain pipe 4 is connected to the side of the main body 1 below the drain pipe 2. The oil squeezed out of the modified polyurethane sponge 9 enters the oil drain pipe 4 and can flow back to the bottom end of the main body 1 for unified collection and discharge.

[0035] The working principle of this technical solution is as follows: when using this device, the oil-containing water is poured into the water collection tank 3 and enters the main body 1 under the action of gravity. In the process of passing through the modified polyurethane sponge 9, the oil is adsorbed on the surface of the modified polyurethane sponge 9, while the water falls to the bottom of the modified polyurethane sponge 9 through the pores of the modified polyurethane sponge 9 and is discharged through the drain pipe 2; when it is necessary to clean the modified polyurethane sponge 9 to ensure the oil absorption effect of the modified polyurethane sponge 9, open the oil drain pipe 4 and the oil drain valve 6, buckle the pull ring 84 and rotate the connecting rod 81 to rotate the positioning block 82 on the connecting rod 81 to the bottom of the plug-in slot 72, and then slide the mounting bracket 8 upward to make the mounting bracket 8 as a whole. The modified polyurethane sponge 9 installed between the base frame 83 and the fixing frame 7 is squeezed, so that the oil retained in the pores of the modified polyurethane sponge 9 is squeezed out, and part of the squeezed oil enters the sump 3 and flows into the bottom end of the main body 1 through the oil drain pipe 4, while the other part of the oil directly enters the bottom end of the main body 1 and is then discharged and collected through the opened oil drain valve 6; when the modified polyurethane sponge 9 needs to be replaced, the nut screwed on the screw 10 is removed, and then the fixing frame 7 is removed, and then the mounting frame 8 is slid out of the main body 1, and then the base frame 83 is unscrewed, and the original modified polyurethane sponge 9 can be slid out from the outside of the connecting rod 81 and replaced with a new modified polyurethane sponge 9.
