Therefore, the absolute viscosity coefficient of grease in the sewage can be reduced along with the temperature rise, the floating speed of the grease can be increased, the grease floats on the sewage liquid surface, and the oil-water separation is facilitated. The multi-layer corrugated plate set 140 is disposed in the coalescing region 114, and the multi-layer corrugated plate set 140 can coalesce two or more oils into one oil, so that the particle radius of the oil becomes larger, the floating speed of the oil increases, and the oil in the sewage flows to the oil scraping region 115 more easily through the third partition plate 123, which is beneficial to improving the oil-water separation efficiency.
According to some embodiments of the utility model, the heating device 130 is an electrical heating rod. Referring to fig. 7 and 9, the shape of the electric heating rod is not particularly limited, and may satisfy the heating requirement in the separation chamber 110.

The oil scraping end of the oil scraping device 400 contacts with the sewage in the oil-water separation device 100, and the oil scraping end can scrape the grease floating on the liquid surface of the sewage into the oil scraping device 400. In some examples, the oil scraping end may scrape the oil out of the oil-water separation device 100 through rotation, so that the oil can be rapidly separated, and thus the oil-water separation efficiency can be improved.
In some examples, the oil scraping device 400 is disposed in the oil scraping area 115, and as the heating device 130 heats, the oil floats on the sewage surface, and then the oil scraping device 400 can scrape the oil in the surface out of the oil-water separation device 100, and the oil scraping device 400 and the heating device 130 cooperate with each other, so that the oil-water separation efficiency is improved.
The oil collecting device 500 is communicated with the oil discharging end of the oil scraping device 400, and the oil collecting device 500 is also communicated with the oil discharging port 111 for collecting oil. The discharged oil is stored in the oil collecting device 500 by the oil separation means of the oil scraping device 400 and the oil-water separation device 100, and the oil in the oil collecting device 500 can be recovered and reused.
In some examples, as shown in fig. 4, an oil collecting tank 501 and an oil pump 502 may be further disposed between the oil scraping device 400 and the oil collecting device 500, where the oil collecting tank 501 is used for collecting the oil scraped by the oil scraping device 400, and after the oil is stored to a certain volume, the oil is rapidly discharged into the oil collecting device 500 through the oil pump 502, thereby improving the efficiency of oil recovery.
