[0027] In order to enable those skilled in the art to better understand the technical solutions in the present utility model, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model 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 the embodiments. Based on the embodiments in 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.

[0028] In the description of the present utility model, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "top", "bottom", "vertical", "horizontal", "axial", "radial", "circumferential", etc. are based on the orientation or positional relationships shown in the accompanying drawings. These are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0029] Refer to Figures 1 to 5 As shown, an embodiment of the present utility model provides an oil pot for a three - stage oil - gas recovery device, which includes a pot body 1, a heat - exchange plate 2, and a liquid - guiding pipe 3.

[0030] Specifically, in this embodiment, a liquid - storage cavity is provided inside the pot body 1. At least part of the side wall of the pot body 1 is made of a transparent material. A liquid inlet 1111 and an exhaust port 1112 are provided on the first side of the pot body 1, and a liquid discharge port 1211 is provided on the second side. The heat - exchange plate 2 is arranged in the liquid - storage cavity, and through - holes 201 are provided on the heat - exchange plate 2. The liquid - guiding pipe 3 is at least partially arranged in the liquid - storage cavity. One side of the liquid - guiding pipe 3 is communicated with the liquid inlet 1111, and the other side penetrates through the heat - exchange plate 2.

[0031] According to the above - mentioned structural design, the liquid inlet 1111 on the pot body 1 is connected to the oil - gas recovery system of the three - stage oil - gas recovery device, and is used to receive the mixture of liquid oil and gaseous oil transported by the oil - gas recovery system.

[0032] This mixture enters the liquid - storage cavity through the liquid - guiding pipe 3. Among them, the liquid oil flows out of the oil pot through the liquid discharge port 1211 and is transported to a storage container. The gaseous oil flows towards the exhaust port 1112 and is transported to the oil - gas recovery system or other storage containers again. During the flow of the gaseous oil, when passing through the heat - exchange plate 2, it can transfer heat to the heat - exchange plate 2, so that part of the gaseous oil is cooled into liquid oil and flows through the through - holes 201 on the heat - exchange plate 2 to the bottom of the heat - exchange plate 2, and finally flows out of the oil pot through the liquid discharge port 1211.

[0033] In the above process, since the side wall part of the kettle body 1 is made of a transparent material, the user can observe the liquid level of the liquid oil in the liquid storage cavity from this transparent part, and observe the color, volume and other physically observable properties of the liquid oil in the liquid storage cavity, so as to roughly judge the key parameters such as the quality, volume and recovery rate of the liquid oil.

There are openings on both sides of the annular shell 13. The first cover 11 and the second cover 12 are respectively detachably and sealingly connected to the two openings of the annular shell 13 to prevent oil and gas leakage on both sides of the annular shell 13.

[0036] Moreover, the entire annular shell 13 is made of a transparent material, and the user observes the liquid oil in the liquid storage cavity through the transparent part on the annular shell 13.

[0037] Preferably, the first cover 11 in this example includes a first plate part 111 and a first skirt part 112. The first skirt part 112 is arranged on the side of the first plate part 111 facing the second cover 12. The second cover 12 in this example includes a second plate part 121 and a second skirt part 122.
