[0060] The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0061] As Figure 1 shown, an oil separator provided by an embodiment of the present utility model includes: a separation tank 1, a vacuum pump 2, a pressure gauge 3, a heating assembly 4, a liquid level sensor 5, a liquid inlet assembly 6, a liquid discharge assembly 7, and a controller 8. The top of the separation tank 1 has a pressure relief port 11, and a heat exchange chamber 12 is provided inside the side wall of the separation tank 1. The vacuum pump 2 is communicated with the inside of the separation tank 1. The pressure gauge 3 is arranged on the separation tank 1, and its detection end extends into the separation tank 1. The heating assembly 4 is communicated with the heat exchange chamber 12 of the separation tank 1. The liquid level sensor 5 is installed inside the tank body of the separation tank 1. The liquid inlet assembly 6 is communicated with the inside of the separation tank 1, and the liquid discharge assembly 7 is communicated with the bottom of the separation tank 1. The controller 8 is electrically connected to the vacuum pump 2, the pressure gauge 3, the heating assembly 4, the liquid level sensor 5, the liquid inlet assembly 6, and the liquid discharge assembly 7.

[0062] When the used lubricating oil or cooling oil needs to be separated, it enters the separation tank 1 through the liquid inlet assembly 6. When the position height of the oil liquid reaches the preset maximum value, the liquid level sensor 5 feeds back the information to the controller 8, and the controller 8 controls the channel of the liquid inlet assembly 6 to close and stop the liquid inlet. This avoids excessive oil liquid in the separation tank 1 and affects the separation efficiency. During the separation process, the separation tank 1 is evacuated to a vacuum environment by the vacuum pump 2, and then the heating assembly 4 heats the separation tank 1. When heated to a certain temperature, the oil liquid in the separation tank 1 boils, so that the water in the oil liquid is evaporated. After heating to a certain temperature, the heating assembly 4 is controlled to keep warm, effectively reducing the energy consumption of the equipment. The separated oil liquid is discharged from the separation tank 1 through the liquid discharge assembly 7, which is convenient for subsequent treatment of the oil liquid. Before discharging the liquid, first relieve the pressure through the pressure relief port 11 to facilitate the discharge of the oil liquid.

[0063] When evacuating the vacuum, to avoid damage to the separation tank 1, the pressure inside the separation tank 1 is detected in real time by the pressure gauge 3, and the real-time data of the pressure is fed back to the controller 8. When the preset maximum value is reached, the controller 8 controls the vacuum pump 2 to stop.

[0064] In one embodiment, as Figure 1 shown, in order to improve the safety of the separation tank 1 during use, an automatic pressure relief valve 9 is provided at the pressure relief port 11, and the controller 8 is electrically connected to the pressure relief valve.

[0065] During the separation process, when the pressure exceeds the preset maximum value, the automatic pressure relief valve 9 is controlled to open for pressure relief to avoid damage to the separation tank 1.

[0066] In one embodiment, the heating component 4 is a waste heat heating component 4, an electric heating component 4, or a steam heating component 4.

[0067] As Figure 1 and Figure 2 shown, when the heating component 4 is a waste heat heating component 4, the heating component 4 includes: a conveying pipeline 41, a conveying valve 42, a heating plate 43, a temperature sensor 44, and a heat preservation layer 45. One end of the conveying pipeline 41 is communicated with the waste heat output component, and the other end is connected to the heat exchange chamber 12. The conveying valve 42 is installed on the conveying pipeline 41, and the controller 8 is electrically connected to the conveying valve 42. The heating plate 43 is wrapped outside the conveying pipeline 41 and is electrically connected to the controller 8. The temperature sensor 44 is installed at one end of the conveying pipeline 41 close to the separation tank 1 and is electrically connected to the controller 8. The heat preservation layer 45 is wrapped outside the heating plate 43.

[0068] In order to reduce the energy consumption of the separator, the waste heat of other equipment is used to heat the separation tank 1. During heating, the conveying valve 42 is opened, and the steam with heat from the preheating output component enters the conveying pipeline 41, and then enters the heat exchange chamber 12 of the separation tank 1 through the conveying pipeline 41 for heat exchange. After heat exchange, the steam is directly discharged outside through the opening communicated with the heat exchange chamber 12. Since there will be a certain amount of heat loss during the conveying process of the steam with heat, a temperature sensor 44 is provided at one end of the conveying pipeline 41 close to the separation tank 1 to detect whether the temperature reaches the standard through the temperature sensor 44. When the temperature is lower than the preset value, the information is fed back to the controller 8, and the controller 8 controls the heating plate 43 to work.

[0069] The heat preservation layer 45 is provided outside the heating plate 43 to reduce the heat loss of the steam with temperature during the conveying process and at the same time reduce the energy consumption of the separator.

[0070] In one embodiment, as Figure 1 shown, the oil separator further includes: a cooling component 10, and the cooling component 10 is used to cool down the vacuum pump 2.

[0071] More specifically, the cooling assembly 10 includes: a cooling tank 101, a cooling pipe 103, a delivery pump 104, and a temperature sensor 105. The cooling tank 101 is filled with a cooling medium 102. Both ends of the cooling pipe 103 are communicated with the cooling tank 101, and the middle part of the cooling pipe 103 is wound around the outside of the vacuum pump 2. The delivery pump 104 is installed on the cooling pipe 103 and is electrically connected to the controller 8. The temperature sensor 105 is installed on the vacuum pump 2 and is electrically connected to the controller 8.

[0072] During use, the temperature sensor 105 is used to detect the temperature of the vacuum pump 2 during operation, so as to avoid the temperature of the vacuum pump 2 being too high and affecting the service life of the vacuum pump 2. Therefore, when the temperature sensor 105 senses that the temperature on the vacuum pump 2 is higher than the preset value, it feeds back the information to the controller 8, and the controller 8 controls the delivery pump 104 to work. The delivery pump 104 delivers the cooling medium 102 in the cooling tank 101 into the cooling pipe 103, and the temperature of the vacuum pump 2 is taken away through the circulation of the cooling medium 102.

[0073] It should be noted that the cooling medium 102 can be water or cooling oil.

[0074] In another embodiment, a refrigerator can be used to quickly cool the cooling medium 102 in the cooling tank 101. The refrigerator and the installation method of the refrigerator are prior arts and will not be elaborated here.

[0075] In another embodiment, as Figure 1 shown, the liquid inlet assembly 6 includes: a liquid inlet pipe 61, a liquid inlet funnel 62, and a liquid inlet valve 63. One end of the liquid inlet pipe 61 is communicated with the inside of the separation tank 1. The liquid inlet funnel 62 is arranged at the other end of the liquid inlet pipe 61. The liquid inlet valve 63 is arranged on the liquid inlet pipe 61 and is electrically connected to the controller 8.

[0076] When liquid needs to be inlet, the liquid inlet valve 63 is in an open state, and the oil liquid enters the liquid inlet pipe 61 through the liquid inlet funnel 62, and then enters the separation tank 1 through the liquid inlet pipe 61. When the oil liquid in the separation tank 1 reaches the preset liquid level height, it feeds back the information to the controller 8, and the controller 8 controls the liquid inlet valve 63 to close.

[0077] It should be noted that the user can add liquid manually through the liquid inlet funnel 62, or can dock the liquid inlet funnel 62 with the pipeline of an external device, and then the external device provides the oil liquid to the liquid inlet funnel 62.

[0078] In one of the embodiments, as Figure 1As shown, the liquid discharge assembly 7 includes: a liquid discharge pipeline 71 and a liquid discharge valve 72. One end of the liquid discharge pipeline 71 is communicated with the bottom of the separation pipeline, and the other end is connected to an external storage device. The liquid discharge valve 72 is arranged on the liquid discharge pipeline 71 and is electrically connected to the controller 8.

[0079] When the oil liquid of the mixed water needs to be discharged for further treatment after preliminary treatment in the separation tank 1, the liquid discharge valve 72 is controlled to open by the controller 8, and the oil liquid enters the external storage device through the liquid discharge pipeline 71 or directly enters another processing device for further treatment.

[0080] In one embodiment, as Figure 1 shown, in order to facilitate the operator to observe the separation situation in the separation tank 1, an observation window 13 is provided on the side wall of the separation tank 1.

[0081] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
