[0030] like Figure 1 As shown, this embodiment provides an automatic separation device that utilizes the immiscibility and density difference between the light and heavy phases in a mixture to achieve separation. It can be used for the recycling and reuse of organic matter in wastewater, as well as in other scenarios requiring separation.

[0031] The automatic separation device includes a phase separation tank 1, a heavy phase receiving tank 2, a light phase receiving tank 3, a U-shaped pipe 4, a vent valve 5, and a drain valve 6. The phase separation tank 1 has a heavy phase outlet 11 and a light phase outlet 12. The heavy phase outlet 11 is located at the bottom of the phase separation tank 1, and the light phase outlet 12 is located on the side wall of the phase separation tank 1. The two ends of the U-shaped pipe 4 are connected to the heavy phase outlet 11 and the heavy phase receiving tank 2, respectively. The light phase receiving tank 3 is connected to the light phase outlet 12. The vent valve 5 is installed at the highest point of the U-shaped pipe 4, and the drain valve 6 is installed at the lowest point of the U-shaped pipe 4. The height of the highest point of the U-shaped pipe 4 is higher than the height of the separation interface 100 between the heavy and light phases in the mixture. The mixture to be separated is continuously fed into the phase separation tank 1. The light and heavy phases in the mixture are immiscible and have different densities. Because the height of the light phase outlet 12 is higher than the height of the highest point of the U-shaped pipe 4, there is a height difference between the light phase outlet 12 and the highest point of the U-shaped pipe 4. There is also a height difference between the liquid levels at both ends of the U-shaped pipe 4, causing the light and heavy phases in the mixture to stratify and form a stratification interface 100. This ensures continuous and automatic separation of the mixture without the need for settling, improving separation efficiency, reducing operator time and workload, and saving labor costs. The drain valve 6 is installed at the lowest point of the U-shaped pipe 4 to facilitate the discharge of impurities from the mixture and to facilitate periodic cleaning of the phase separation tank 1. The vent valve 5 is installed at the highest point of the U-shaped pipe 4 to block the siphon effect during the discharge of the heavy phase, making the wastewater recovery and separation more thorough and ensuring the separation effect.

[0032] Specifically, the U-shaped pipe 4 is U-shaped with different heights at both ends. The lower end of the U-shaped pipe 4 is connected to the heavy phase discharge outlet 11, and the higher end of the U-shaped pipe 4 is connected to the heavy phase receiving tank 2.

[0033] More specifically, the lower end of the U-shaped pipe 4 is higher than the lowest point of the U-shaped pipe 4, and the higher end of the U-shaped pipe 4 is level with the highest point of the U-shaped pipe 4.

[0034] In this embodiment, when the mixture is wastewater, the ethyl acetate in the wastewater needs to be recovered and reused. Since the density of ethyl acetate is less than that of water, ethyl acetate is the light phase and water is the heavy phase. Ethyl acetate is located on the upper layer of water, and a separation interface 100 will appear between the two.

[0035] like Figure 1 As shown, the height difference between the highest and lowest points of the U-shaped pipe 4 is h, the height difference between the light phase outlet 12 and the highest point of the U-shaped pipe 4 is h1, the height difference between the lowest point of the U-shaped pipe 4 and the layered interface 100 is h3, and the height difference between the highest point of the U-shaped pipe 4 and the layered interface 100 is h2. Therefore, h = h2 + h3.

[0036] According to the liquid pressure balance principle: ρ 水 gh=ρ 水 gh3+ρ 乙酸乙酯 g(h1+h2), it is known that the height difference h1 between the light phase discharge outlet 12 and the highest point of the U-shaped pipeline 4 is 100 mm, the height difference h between the highest point and the lowest point of the U-shaped pipeline 4 is 2600 mm, the height difference h3 between the lowest point of the U-shaped pipeline 4 and the stratification interface 100 is 1700 mm, and the height difference h2 between the highest point of the U-shaped pipeline 4 and the stratification interface 100 is 900 mm.

[0037] It should be noted that in actual operation, due to the influence of factors such as temperature and impurities of the sewage, the values of h, h1, h2 and h3 will have small fluctuations, but will always maintain a stable liquid level.

[0038] Further, the automatic separation device further comprises a heavy phase discharge pipe 9, one end of the heavy phase discharge pipe 9 being in communication with the end of the U-shaped pipeline 4, and the other end being in communication with the heavy phase receiving tank 2.

[0039] Specifically, one end of the heavy phase discharge pipe 9 is in communication with the higher end of the U-shaped pipeline 4.

[0040] Further, the automatic separation device further comprises a light phase discharge pipe 8, one end of the light phase discharge pipe 8 being in communication with the light phase discharge outlet 12, and the other end being in communication with the light phase receiving tank 3.

[0041] Further, the automatic separation device further comprises a viewing mirror 7, the viewing mirror 7 being installed on the light phase discharge pipe 8 and being located at the same horizontal plane as the light phase discharge outlet 12. The setting of the viewing mirror 7 can facilitate the observation of the discharge of the light phase.

[0042] Further, the phase separation tank 1 has a feed inlet 13 located at the top of the phase separation tank 1 to facilitate the pouring of the mixed material.

[0043] Although the utility model has been described in detail above with general description, specific embodiments and tests, some modifications or improvements can be made on the basis of the utility model, which is obvious to those skilled in the art. Therefore, these modifications or improvements made on the basis of not deviating from the spirit of the utility model, all belong to the scope of protection required by the utility model.
