DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be apparently and completely described in connection with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the ordinary skilled in the art without creative labor fall within the protection scope of the utility model.

[0021] With reference to Figures 1-4 The utility model provides an embodiment: an automatic oil -water separation machine, including body 1, body 1 top rotatable connection has apron 2, apron 2 side wall fixedly connected with the residue separation basket 3, body 1 inside fixedly connected with two separation baffle 8, body 1 inside fixedly connected with final separation baffle 9, final separation baffle 9 inside is set with adjustable water outlet 10, body 1 inside is set with oil outlet 11, body 1 inside slidingly connected with the oil guide plate 4, the oil guide plate 4 upper surface fixedly connected with pull handle 5, body 1 outer wall fixedly connected with electric heater 6, body 1 inside fixedly connected with magnetic suspension heating disc 7, body 1 outer wall fixedly connected with oil drain pipe 12, oil drain pipe 12 is fixedly connected in oil outlet 11 inside, body 1 outer wall fixedly connected with drain pipe 13, drain pipe 13 is fixedly connected in adjustable water outlet 10 inside, body 1 side wall is provided with blow-off valve 14.

[0022] Specifically, during operation, the mixture of oil-containing sewage and kitchen waste flows into the body 1, and then enters the debris basket 3 under the guidance of the oil guide plate 4. The debris basket 3 can effectively intercept and separate large pieces of kitchen waste, thereby completing the preliminary separation of large-particle impurities. After the preliminary separation of large-particle impurities, the oil-water mixture enters the gravity settling zone. In this zone, due to the physical property that the density of oil is less than that of water, oil droplets begin to float upward under the action of gravity, while water settles downward. Then, the oil-water mixture enters the secondary separation zone separated by the secondary separation partition plate 8, where the separation process is continuously promoted based on the density difference between oil and water. Oil droplets continue to float upward and gather above the water surface, forming an oil layer, while the water layer is at the bottom position. Next, the oil-water mixture after secondary separation enters the final separation zone divided by the final separation partition plate 9 for further separation. During the entire oil-water separation process, the magnetic suspension heating disc 7 is continuously in operation, which can maintain the oil-water mixture in a liquid state at all times, ensuring good fluidity of the mixture. This good fluidity is extremely beneficial to the floating of oil droplets and the flow of water, effectively promoting the smooth progress of the separation process. When the upper floating oil accumulates to the height of the oil discharge port 11, the floating oil will automatically flow out of the body 1 through the oil discharge pipe 12, while the water will flow out through the adjustable water outlet 10 on the final separation partition plate 9 and the connected drain pipe 13 under the action of the communicating vessel principle. According to different working conditions such as more oil and less water or less oil and more water, the water level can be flexibly controlled by adjusting the height of the adjustable water outlet 10. For example, in the case of more oil and less water with large oil output, the height of the water outlet can be appropriately lowered to make the oil-water separation more complete and avoid high water content in the oil. In the case of less oil and more water with small processing capacity, the water outlet can be raised to increase the water level, achieve more complete drainage, reduce the oil storage in the equipment, and reduce the impact of residual oil in the equipment on the subsequent separation effect and the risk of equipment failure. In addition, the blowdown valve 14 provided on the side wall of the body 1 can be used for periodic cleaning of the impurities and other substances deposited in the equipment. By periodically opening the blowdown valve 14, the impurities deposited at the bottom of the equipment can be discharged, keeping the equipment clean and ensuring stable operation of the equipment, prolonging the service life of the equipment, improving the operation efficiency and reliability of the equipment, and ensuring long-term stable operation of the oil-water separation work, meeting the processing needs of the mixture of oil-containing sewage and kitchen waste under different working conditions.

[0023] Working principle: when working, the mixture of oil-containing sewage and kitchen garbage flows into the body 1, and is first guided into the residue separation basket 3 through the oil guide plate 4, the residue separation basket 3 intercepts and separates out the large kitchen garbage, and the oil-water mixture after the preliminary separation of the large-particle impurities enters the gravity sedimentation area, in the area, due to the smaller density of oil than water, the oil droplets begin to gradually float up under the action of gravity, and then the oil-water mixture enters the second separation area separated by the second separation baffle 8, and is further separated by relying on the density difference between oil and water, the oil droplets continue to float up and gather on the water surface to form an oil layer, and the water layer is at the bottom, then the oil-water mixture after the second separation enters the final separation area divided by the final separation baffle 9 for reseparation, in the whole separation process, the magnetic suspension heating disc 7 continuously works to keep the oil-water mixture in liquid state all the time, ensuring good fluidity, which is conducive to the floating of oil droplets and the flow of water, when the upper floating oil accumulates to the height of the oil discharge port 11, the floating oil will automatically flow out along the oil discharge port 11 through the oil discharge pipe 12, and the water will flow out through the adjustable water outlet 10 on the final separation baffle 9 and the drain pipe 13 connected thereto under the principle of communicating vessels, and according to different working conditions such as more oil and less water or less oil and more water, the water level can be controlled by adjusting the height of the adjustable water outlet 10, in the case of more oil and less water and large oil discharge amount, the water outlet is appropriately adjusted downward to make the separation more thorough, in the case of less oil and more water and small processing amount, the water outlet is adjusted upward to raise the water level line, so that the water is completely discharged and the oil storage in the equipment is reduced, at the same time, the blowdown valve 14 on the side wall of the body 1 can be used for periodic cleaning of the deposited impurities in the equipment.
