[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0025] Refer to Figure 2 、 Figure 3 and Figure 4, an embodiment provided by the utility model: a wastewater oil separation device, including a fixed frame 1, on one side of the inner wall of the fixed frame 1, there is a liquid level lifting control box 5 fixedly connected. Inside the liquid level lifting control box 5, there is a first water inlet pipe 7. Inside the liquid level lifting control box 5, there is a hydraulic cylinder 13. The output end of the hydraulic cylinder 13 is fixedly connected with a second baffle 33. Inside the liquid level lifting control box 5, there is a second water inlet pipe 17. Inside the liquid level lifting control box 5, there is a fixed plate 14 fixedly connected. On one side of the outer wall of the fixed plate 14, there are symmetrically arranged hydraulic rods 20 in the up-down, left-right directions. The output end of the hydraulic rod 20 is fixedly connected with a pressing plate 18. The pressing plate 18 is slidably connected inside the liquid level lifting control box 5. On one side of the outer wall of the pressing plate 18, there is a first spring 21 fixedly connected. One end of the first spring 21 is fixedly connected to one side of the outer wall of the fixed plate 14. Inside the liquid level lifting control box 5, there are symmetrically arranged first baffles 31 in the up-down direction. The first baffles 31 are in contact with the pressing plate 18. Inside the liquid level lifting control box 5, there is a ventilation opening 19 penetratingly opened. Inside the second water inlet pipe 17, there is an adjusting 23 component for conveying water. The adjusting component includes a liquid blocking plug 22. Inside the liquid blocking plug 22, there is a piston 23 slidably connected. Inside the piston 23, there is a second spring 24 fixedly connected. One end of the second spring 24 is fixedly connected to the inner wall of the liquid blocking plug 22;
[0026] Specifically, pour the aqueous solution into the liquid level lifting control box 5 through the first water inlet pipe 7. Start the hydraulic cylinder 13 to push the second baffle 33 to squeeze the air inward, resulting in an increase in the pressure inside the cavity. The air pushes the pressing plate 18 to squeeze the first spring 21, making it slide slowly inside. Finally, when the gas encounters the ventilation opening 19, it will be pushed into another cavity. Then the pressing plate 18 returns to normal through the elastic deformation of the first spring 21; the gas enters another cavity and presses the aqueous solution into the second water inlet pipe 17. At this time, the aqueous solution gives an outward pressure to the piston 23, the second spring 24 undergoes elastic deformation, and the liquid enters the separation box 4 through the liquid blocking plug 22. Then the second spring 24 returns to normal and the liquid no longer passes through the liquid blocking plug 22.
[0027] Refer to Figure 1 , Figure 2 , Figure 5 and Figure 6, an electric telescopic rod 2 is fixedly installed on the upper surface of the fixing frame 1. The output end of the electric telescopic rod 2 is fixedly connected to a connecting frame 6. An electric slide rail 32 is fixedly installed inside the connecting frame 6. A limiting rod 26 is slidably connected inside the fixing frame 1. One end of the limiting rod 26 is fixedly connected to one side of the outer wall of the connecting frame 6. A collar 11 is slidably connected to the outer wall of the electric slide rail 32. A connecting block 25 is fixedly connected to the outer wall of the collar 11. An oil scraping plate 12 is fixedly connected to the lower surface of the connecting block 25. An oil storage tank 3 is fixedly installed on the inner wall of the fixing frame 1. A separation box 4 is fixedly installed on one side of the outer wall of the oil storage tank 3. A sewage inlet pipe 30 penetrates through the inside of the separation box 4. An air inlet pipe 29 penetrates through the inside of the separation box 4. A solid-liquid separation net 15 is slidably connected inside the separation box 4. A fixing seat 9 is fixedly installed on one side of the outer wall of the fixing frame 1. A filter box 10 is fixedly installed on the upper surface of the fixing seat 9. A filter net 16 is slidably connected inside the filter box 10. A water pump 8 is fixedly connected to the upper surface of the fixing seat 9. The input end of the water pump 8 is fixedly connected to the inside of the separation box 4. The output end of the water pump 8 is fixedly connected to the inside of the filter box 10. A small air flow pump 27 is fixedly installed on the upper surface of the fixing seat 9. The output end of the small air flow pump 27 is fixedly connected to a connecting pipe 28. The connecting pipe 28 is fixedly connected to one end of the air inlet pipe 29;
[0028] Specifically, when the oil stain enters the separation box 4, it first passes through the solid-liquid separation net 15 for the first filtration to separate the larger particulate oil stains in the waste water and oil stains. Then, when the sewage liquid in the separation box 4 reaches the required height, the small air flow pump 27 is started to generate small bubbles in the separation box 4 to quickly separate the oil layer and the aqueous solution layer. Then, the electric telescopic rod 2 is started, and its output end controls the connecting frame 6 to descend or ascend to reach the specified position, and then it is limited by the limiting rod 26; the electric slide rail 32 drives the collar 11 to slide, thereby driving the oil scraping plate 12 below to scrape off the oil layer on the liquid surface; the scraped oil stain layer enters the oil storage tank 3, and the remaining relatively clean sewage liquid is pumped into the filter box 10 by the water pump 8, and clean aqueous solution is obtained after passing through the filtration of the filter net 16.
[0029] Working principle: The oil stains in industrial production enter the separation tank 4 through the sewage inlet pipe 30, flow through the solid-liquid separation net 15 and are filtered for the first time to separate larger particles in the wastewater; when the liquid level of the oil stain liquid in the separation tank 4 is relatively low, the hydraulic cylinder 13 is started, and its output end pushes the second baffle 33 to squeeze the air inside the container, so the pressure inside the container increases, which will give the pressing plate 18 an inward force. Since there is a ventilation opening 19 inside the liquid level lifting control box 5, the pressure caused by the air pressure reaches equilibrium as the gas flows out, and the first spring 21 and the hydraulic rod 20 beside it adjust the pressing plate 18 to return to its position; at this time, the squeezed gas reaches the chamber on the other side where the aqueous solution is placed, squeezes the aqueous solution into the second water inlet pipe 17, causes an outward pressure on the piston 23, and the piston 23 moves outward through the elastic deformation of the second spring 24 to conduct the second water inlet pipe 17, and finally the piston 23 returns to its position through the second spring 24; when the sewage liquid level drops to the required height, the small air flow pump 27 is started to generate small bubbles in the separation tank 4 to quickly separate the oil layer and the aqueous solution layer, and then the electric telescopic rod 2 is started to drive the connecting frame 6 to move up and down, and is limited by the limiting rod 26 to reach the designated position. The electric slide rail 32 drives the collar 11 to slide, thereby driving the oil scraping plate 12 below to scrape the oil layer on the liquid surface; the scraped oil layer enters the oil storage tank 3, and the remaining relatively clean sewage liquid is pumped into the filter tank 10 by the water pump 8, and finally clean aqueous solution is obtained after filtering through the filter net 16, realizing the separation and pretreatment of wastewater oil stains.
[0030] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
