DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3The embodiment of the utility model provides a technical solution: a high-efficiency oil-water separator, including a box body 1, wherein a first partition plate 2 and a second partition plate 3 are sequentially arranged inside the box body 1 from left to right, and the inside of the box body 1 is divided into three areas by the first partition plate 2 and the second partition plate 3, the left side of the first partition plate 2 is a water outlet area 4, the right side of the first partition plate 2 is an oil-water separation area 5, and the right side of the second partition plate 3 is an oil outlet area 6, the water outlet area 4 and the oil-water separation area 5 are connected at the bottom, and the oil-water separation area 5 and the oil outlet area 6 are connected at the top, a honeycomb structure 7 is arranged on the left side of the second partition plate 3, a water outlet 8 and an oil outlet 9 are respectively arranged on the left and right sides of the box body 1, a slag discharge port 12, an air inlet 11 and a water inlet 10 are sequentially arranged on the bottom of the box body 1 from left to right, an air pump 13 is installed on the left side of the top of the box body 1, and the output end of the air pump 13 is connected to the air inlet 11.

[0021] Furthermore, a fixed plate 16 is provided at the top of the box body 1, just above the second partition 3, and an adjusting screw 17 is inserted through the surface of the fixed plate 16. A baffle 18 is threadedly connected to the bottom of the adjusting screw 17, and the bottom of the baffle 18 is movably connected to the top of the second partition 3. Since the water outlet area 4 and the bottom of the oil-water separation area 5 are connected, and the density of oil is less than that of water, the water surface on the right side of the first partition 2 is lower than the water surface on the left side, but the oil surface will be higher than the water surface on the left side. The height of the baffle 18 is adjusted by adjusting the screw 17, so that the oil outlet height can be adjusted to a suitable level to separate the oil.

[0022] Furthermore, a bottom plate 14 is provided at the bottom of the water outlet area 4 and the oil-water separation area 5 . The bottom plate 14 is inclined. The bottom plate 14 is provided at a slope to facilitate the discharge of impurities from the slag discharge port 12 .

[0023] Furthermore, a sealing plate 15 is provided at the air inlet 11, and a plurality of tiny holes are provided on the surface of the sealing plate 15 to facilitate the formation of a large number of bubbles. When the bubbles pass through the honeycomb structure 7, the pressure changes, so that the oil and water are quickly separated, which is the so-called flotation separation technology.

[0024] Working principle: When in use, the staff first introduces the waste water into the box body 1 through the water inlet 10, and then starts the air pump 13. The output end of the air pump 13 ventilates the inside of the box body 1 through the air inlet 11, and then a large number of fine bubbles are generated in the waste water through the holes opened on the surface of the sealing plate 15. The bubbles pass through the honeycomb structure, and the pressure changes, so that the oil and water are quickly separated, which is the so-called flotation separation technology. Then, the adjusting screw 17 is turned to adjust the height of the baffle 18 by adjusting the screw 17. By adjusting the appropriate oil outlet height, the oil and water can be separated, and then the oil can be discharged through the oil outlet 9.
