Description

Technical Field

[0001] The utility model relates to the technical field of oil purification equipment, in particular to a vacuum heating oil-water separation tank used for waste oil purification. Background Art

[0002] When purifying waste oil, separation tanks are often used to separate oil and water. However, the oil-water separation tanks currently on the market have low efficiency and incomplete separation when separating the emulsified oil-water mixture, and the overall separation effect is poor, which needs to be improved.

[0003] Therefore, in view of the shortcomings of the above scheme in actual production and implementation, it is revised and improved. At the same time, in the spirit and concept of seeking excellence, with the assistance of professional knowledge and experience, and after many ingenuity and experiments, a vacuum heating oil-water separation tank for waste oil purification is provided to solve the technical problems of low separation efficiency and incomplete separation of the existing oil-water separation tank when separating the emulsified oil-water mixture. Utility Model Content

[0004] The utility model aims to provide a vacuum heating oil-water separation tank for waste oil purification, which is used to solve the technical problems of low separation efficiency and incomplete separation of the existing oil-water separation tank when separating the emulsified oil-water mixture.

[0005] The technical solution of the utility model is achieved in this way:

[0006] A vacuum heated oil-water separation tank for waste oil purification comprises a separation tank body, wherein the separation tank body comprises a first tank body and a second tank body, wherein the second tank body is arranged at the bottom of the first tank body and the first tank body is connected to the second tank body, wherein the first tank body is provided with a vacuum pump, an oil discharge port and an oil inlet, wherein the oil discharge port is higher in the vertical direction than the oil inlet, wherein the first tank body comprises a heating belt arranged in an interlayer, wherein first viewing windows are arranged at both ends of the first tank body, and wherein a drain port is arranged at the bottom of the second tank body.

[0007] As a preferred embodiment, the first tank body is in the shape of a horizontally placed cylinder, and the second tank body is arranged in a vertical direction.

[0008] As a preferred embodiment, it includes a second window in the shape of an elongated strip, which is arranged parallel to the second tube body, the top of the second window is connected to the side of the bottom of the first tank body, and the bottom of the second window is connected to the side of the bottom of the second tank body.

[0009] The second tank body is arranged at the bottom of the first tank body, so the first tank body and the second tank body are connected in the vertical direction and are not at the same vertical height. The first window can observe the oil-water separation in the first tank body. We set a second window close to the second tank body here, which almost covers the horizontal height range of the second tank body, so as to facilitate the observation of the second tank body.

[0010] Here, the top of the second window is connected to the side of the bottom of the first tank body, and the bottom of the second window is connected to the side of the bottom of the second tank body. The "bottom of the first tank body" and the "bottom of the second tube body" mentioned are positions close to the bottom, not necessarily the exact bottom, and the drain outlet is located at the exact bottom of the second tank body.

[0011] As a preferred embodiment, the heating belt is spiral-shaped and is arranged in an interlayer of the tank wall of the first tank body.

[0012] As a preferred implementation, the vacuum pump is arranged at the top of the first tank body.

[0013] This scheme is to separate oil and water by negative pressure. Based on the principle that oil and water have different evaporation rates in a vacuum environment, oil and water are separated by adjusting the air pressure. The principle of vacuum separation of oil and water is based on the difference in boiling points of oil and water. In a vacuum environment, the boiling point of the liquid will decrease, so that the liquid can evaporate at a lower temperature. The evaporation rate of different substances is related to the saturated vapor pressure, that is, the saturated vapor pressure of fast evaporation is higher. Therefore, in a vacuum environment, the saturated vapor pressure of oil is lower, and the evaporation rate of oil is slower, while the saturated vapor pressure of water is higher, and the evaporation rate of water is faster. Increasing the temperature will also reduce the viscosity of the oil, which is conducive to separation.

[0014] The beneficial effects of the utility model are:

[0015] The utility model can efficiently separate the emulsified oil-water mixture to achieve the demulsification effect, has high efficiency and high separation degree, has a good separation effect, and solves the technical problems of low separation efficiency and incomplete separation when the existing oil-water separation tank separates the emulsified oil-water mixture.

[0028] like Figure 1 to Figure 6A vacuum heated oil-water separation tank for waste oil purification comprises a separation tank body 4, the separation tank body 4 comprises a first tank body 8 and a second tank body 6, the second tank body 6 is arranged at the bottom of the first tank body 8 and the first tank body 8 is connected to the second tank body 6, a vacuum pump 3, an oil discharge port 1 and an oil inlet 9 are arranged on the first tank body 8, the oil discharge port 1 is higher than the oil inlet 9 in the vertical direction, the first tank body 8 comprises a heating belt 10 arranged in the interlayer, first windows 2 are arranged at both ends of the first tank body 8, and a drain port 7 is arranged at the bottom of the second tank body 6.

[0029] See also Figure 1-Figure 3 The first tank body 8 is in the shape of a horizontal cylinder, and the second tank body 6 is arranged in the vertical direction.

[0030] The overall specifications of the first tank body 8 are larger than those of the second tank body 6. Figure 1-Figure 3 shown.

[0031] It includes a second window 5 in the shape of a long strip, which is arranged parallel to the second tube body, the top of the second window 5 is connected to the side of the bottom of the first tank body 8, and the bottom of the second window 5 is connected to the side of the bottom of the second tank body 6.

[0032] The second tank body 6 is arranged at the bottom of the first tank body 8, so the first tank body 8 and the second tank body 6 are connected in the vertical direction and are not at the same vertical height. The first window 2 can observe the oil-water separation in the first tank body 8. We set a second window 5 close to the second tank body 6 here, which almost covers the horizontal height range of the second tank body 6, so as to facilitate the observation of the second tank body 6.

[0033] Here, the top of the second viewing window 5 is connected to the side of the bottom of the first tank body 8, and the bottom of the second viewing window 5 is connected to the side of the bottom of the second tank body 6. The "bottom of the first tank body 8" and the "bottom of the second tube body" mentioned here are positions close to the bottom, not necessarily the bottom, and the drain port 7 is located at the bottom of the second tank body 6, which can be seen in FIG. Figure 2 .

[0034] The heating belt 10 is spiral-shaped and is disposed in a sandwich layer of a tank wall 11 of the first tank body 8 .

[0035] The vacuum pump 3 is arranged at the top of the first tank 8 .

[0036] This scheme is to separate oil and water by negative pressure. Based on the principle that oil and water have different evaporation rates in a vacuum environment, oil and water are separated by adjusting the air pressure. The principle of vacuum separation of oil and water is based on the difference in boiling points of oil and water. In a vacuum environment, the boiling point of the liquid will decrease, so that the liquid can evaporate at a lower temperature. The evaporation rate of different substances is related to the saturated vapor pressure, that is, the saturated vapor pressure of fast evaporation is higher. Therefore, in a vacuum environment, the saturated vapor pressure of oil is lower, and the evaporation rate of oil is slower, while the saturated vapor pressure of water is higher, and the evaporation rate of water is faster. Increasing the temperature will also reduce the viscosity of the oil, which is conducive to separation.

[0037] How to use and principle: see Figure 3 From the perspective of the tank body, the oil-water mixed liquid is first transported to the separation tank body 4 through the oil inlet 9 at the lower right side of the tank body, and negative pressure is generated by the vacuum pump 3 to reduce the pressure in the separation tank body 4 to a level lower than the saturated vapor pressure of the liquid. The liquid is then heated by the heating belt 10 between the tank body interlayers, and the water in the mixed liquid evaporates first, while the oil gradually concentrates. The water gradually settles to the bottom of the tank body due to gravity and can be discharged through the bottom drain port 7. The separated oil is discharged from the oil drain port 1 at the upper right side of the tank body, and the oil-water separation interface can be visually observed in the window of the oil-water separation area.

[0038] The beneficial effects of the utility model are:

[0039] The utility model can efficiently separate the emulsified oil-water mixture to achieve the demulsification effect, has high efficiency and high separation degree, has a good separation effect, and solves the technical problems of low separation efficiency and incomplete separation when the existing oil-water separation tank separates the emulsified oil-water mixture.

[0040] The above is only a preferred embodiment of the utility model, and is not intended to limit the utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in the field to implement; when the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the utility model.
