Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

Please refer to Figures 1-3, an oil-water separation device for oil-water mixtures, including a main body support 1, a separation box 2 is fixed below the main body support 1, and a water inlet pipe 3 is provided on one side of the separation box 2. The other side of the box 2 is provided with a water outlet pipe 4, the water inlet pipe 3 and the water outlet pipe 4 are provided with a valve 5, and the upper end of the main body bracket 1 is fixedly provided with two sets of bearing seats 9, between the two sets of bearing seats 9 A drive shaft 16 is arranged to rotate between them, a metal wheel 10 is fixedly arranged on the drive shaft 16, a cooling plate 11 and a scraper assembly 12 are fixedly arranged above the main body support 1, and the cooling plate 11 is used to cool the metal wheel 10 To lower the temperature, the scraping assembly 12 is used to scrape off the oil on the surface of the metal wheel 10 . The lower part of the main body support 1 is provided with a bottom plate 13 , and an oil tank 14 for storing oil is placed on the bottom plate 13 .

Specifically, a heater 6 is arranged on the outer periphery of the separation box 2, and the heater 6 is used to heat the oil-water mixture in the separation box 2, and the oil-water mixture is auxiliary heated by the heater 6, so as to ensure that the temperature of the oil-water is consistent with that of the metal wheel. The temperature difference between 10 is that the oil is better attached to the surface of the metal wheel 10.

Specifically, the separation box 2 is provided with an oil separator 7, and the oil separator 7 is located between the metal wheel 10 and the water outlet pipe 4. Since the density of the oil is less than that of water, the oil floats on the surface of the water, so The oil separator 7 can effectively block the oil, thereby improving the cleanliness of the water discharged from the outlet pipe 4 .

Specifically, the upper end of the oil separator 7 is obliquely provided with a deflector 8, the upper end of the deflector 8 is in contact with the lower part of the bottom plate 13, and the oil adheres to the surface of the metal wheel 10 under the action of temperature difference, and when it leaves the water surface Finally, it may drip from the metal wheel 10, and setting the deflector 8 can make the dripped oil flow back into the separation box 2, preventing the oil from polluting the environment.

Specifically, a motor 15 is fixedly installed on the main body support 1, and the output end of the motor 15 is fixedly connected with the drive shaft 16, and the drive shaft 16 is driven to rotate by the motor 15 to realize automatic adhesion of oil.

Specifically, the scraper assembly 12 includes a scraper seat 121 , an installation groove 122 is provided at the lower end of the scraper seat 121 , and a scraper 125 is installed at the installation groove 122 . A slider 124 is slidably disposed in the installation groove 122 , the scraper 125 is fixedly installed on the bottom of the slider 124 , and the upper end of the slider 124 is connected to the bottom of the installation groove 122 by a spring 123 . The position of the scraper 125 is adjustable by setting the spring 123, so that the lower end of the scraper 125 conflicts with the metal wheel 10 but does not affect the normal rotation of the metal wheel 10, while ensuring the effect of scraping off the oil on the surface of the metal wheel 10.

Working principle: when the utility model is in use, the temperature of the oil-water mixture is heated to 70-90°C, and then the surface temperature of the stainless steel metal wheel 10 is cooled by air-conditioning, so that the surface temperature of the stainless steel metal wheel 10 is below 5°C. Grease can adhere to stainless steel metal wheel 10 surface immediately when stainless steel metal wheel 10 contacts with oil-water mixture like this, when stainless steel metal wheel 10 rotated to scraper 125 place, scraper 125 automatically scraped off the grease on metal wheel 10 surface, Make grease fall in the oil tank 14. At this time, the surface temperature of the stainless steel metal wheel 10 is relatively high. When the stainless steel metal wheel 10 enters the cooling plate 11, the temperature of the stainless steel metal wheel 10 is lowered by the cold air, so that the surface of the stainless steel metal wheel 10 reaches below 5° C. to realize oil circulation.
