[0002] The discharge of land-based pollutants into the sea pollutes the coastal marine environment and causes ecological damage. The oil film floating on the seawater reduces the oxygen production of the ocean and causes the suffocation and death of marine life. Therefore, it is necessary to separate the oil from the seawater containing oil.

The utility model sets the second treatment mechanism, after the sewage is initially treated, opens the valve on the first drain pipe, the sewage after preliminary treatment enters the filter box through the first drain pipe, the activated carbon filter layer adsorbs and filters the residual grease in the sewage, the sewage after secondary treatment is discharged through the second drain pipe, and the activated carbon filter layer is used to perform secondary treatment on the grease in the sewage, thereby effectively improving the oil-water separation effect.

[0004] In the above-mentioned oil-water separation device, after the static treatment in the first mechanism, the electric push rod is used to realize the rising of the sewage after static treatment, and the dirty oil floating on the upper layer is collected and separated. The remaining liquid is basically water, and then sent to the second mechanism for oil adsorption treatment before discharge. It is found during use that the sewage contains not only oil pollution, but also a large amount of impurities. These impurities will affect the effect and efficiency of oil-water separation. In addition, the rising of the static liquid is realized by the electric push rod, which requires the use of an electric push rod with super-large thrust. The equipment cost is high, and it is also easily damaged by repeated work. For this reason, it is necessary to optimize and improve the current water-oil separation device. Utility Model Content

[0024] Example 1

[0025] As shown in the figure, the processing box 1 is composed of a filtering processing chamber 2, a static separation chamber 3, a dirty oil storage chamber 4 and a second processing chamber 5. The filtering processing chamber 2 is arranged beside the static separation chamber 3 and a through hole 22 is arranged at the connection between the two. The oil discharge port 31 arranged on the static separation chamber 3 is connected to the oil storage chamber 4. The drain port arranged at the lower end of the static separation chamber 3 is connected to the second processing chamber 5 through a water pipe 32. A mounting baffle 7 is arranged at the oil discharge port of the static separation chamber 3. The baffle 7 is arranged in an "L"-shaped structure. The two sides of the baffle 7 are respectively slidably connected to the guide groove of the guide rod 71. The guide rod 71 is fixedly connected to the static separation chamber 3. The upper end of the baffle 7 is connected to the telescopic end of the electric push rod 81 through a connecting block 82. The electric push rod 81 is installed on the processing box 1. The lower end of the baffle 71 is slidably connected to the groove arranged on the side plate of the static separation chamber 3.

[0026] A filter assembly is installed in the filter processing chamber 2. The lower end of the filter screen 62 in the filter assembly is clamped in a clamping block provided on the bottom surface of the filter processing chamber 2. The upper end of the filter screen 62 is connected to a mounting plate 61. The mounting plate 61 is fixedly installed in a mounting groove provided on the top surface of the filter processing chamber 2 by screws. The filter processing chamber 2 is provided with a liquid inlet 21, and a control valve 10 is installed at the liquid inlet 21.

[0027] The second treatment chamber 5 is provided with an adsorption component 5, which is coconut shell activated carbon, and performs grease adsorption treatment on the water discharged after separation treatment to enhance the separation effect.

[0028] A control valve 10 is installed on the water pipe 32 connecting the static separation chamber 3 and the second treatment chamber 5. The oil outlet 41 set in the oil storage chamber 4 and the water outlet 51 set in the second treatment chamber 5 are both equipped with control valves 10 to control the liquid discharge situation. An observation window 11 is provided on the treatment box 1 to facilitate the observation of the separation situation in the static separation chamber 3.

[0029] Example 2

[0030] When the utility model is used, the seawater containing oil pollution enters the filtering treatment chamber 2 of the treatment box 1 from the liquid inlet 21, and the seawater containing oil pollution is initially filtered through the filter screen 62 to filter out impurities in the liquid to avoid affecting the subsequent oil-water separation effect. The filter screen 62 is installed in a detachable manner, which is convenient for disassembly and cleaning of the filter screen 62.

[0031] The seawater after the initial filtration enters the static separation chamber 3 through the through hole 22. When the liquid level sensor 9 installed in the static separation chamber 3 detects the liquid level height, when the liquid level sensor 9 detects that the liquid level reaches the preset value, the detection information is transmitted to the controller 100 installed on the processing box 1, and the control valve 10 on the liquid inlet 21 is controlled to be closed, and the addition of water to the static separation chamber is stopped. After the liquid in the static separation chamber is left to stand for a period of time, due to the different densities of water and oil and the effect of gravity, the oil is located in the upper layer and the water is in the lower layer.

[0032] The water-oil stratification can be observed through the observation chamber 11 on the treatment box 1. The overall liquid level is on the same horizontal line as the upper end of the opening of the oil drain port 31. When the electric push rod 81 is started, the electric push rod 81 pushes the baffle 7 at the oil drain port 31 downward to open the blocked oil drain port 31. The oil separated from the upper layer flows into the oil storage chamber 4 from above the baffle 7. The electric push rod 81 is used to control the downward position of the baffle 7 according to the water-oil separation situation to control the upper end position of the opening of the oil drain port 31. When the liquid height in the static separation chamber 3 is on the same horizontal line as the upper end of the baffle 7, the liquid no longer overflows, and water-oil separation is achieved. The separated dirty oil is stored in the oil storage 4 and discharged through the oil outlet 41 to be transported to the subsequent processing equipment;

[0033] The control valve 10 on the water pipe 32 is opened, so that the sewage separated from the lower layer enters the second treatment chamber 5 through the water pipe 32. The adsorption component 5 made of coconut shell activated carbon material performs grease adsorption treatment on the sewage discharged after the separation treatment to enhance the oil-water separation effect. The sewage after secondary treatment is discharged through the outlet 51.

[0034] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The various components mentioned in the utility model are common technologies in the existing field.
