[0002] Lubricants are primarily composed of base oil and additives. Base oil provides a foundation for lubrication, while additives enhance specific properties. They can reduce friction and wear between mechanical components, prevent rust, provide cooling, and seal. They are widely used in a wide range of fields, including automotive engines and industrial equipment, to ensure efficient and stable operation. However, after prolonged use, lubricants can become contaminated with impurities such as dust, particulate matter, and water. Traditional lubricant recovery methods involve direct treatment of the lubricant through a vacuum filter. However, in actual use, high levels of water are common, and vacuum filters operate at high pressures, necessitating pretreatment to remove water from the lubricant. Utility Model Content

[0006] Preferably, the detection end of the upper liquid level sensor extends into the interior of the processing tank body and above the output pipe, and the detection end of the lower liquid level sensor extends into the interior of the processing tank body and below the output pipe.

[0007] Preferably, a funnel-shaped structure is formed between the lower end of the bottom cover and the discharge pipe, and a manual valve is provided on the discharge pipe.

[0008] Preferably, an input electrically controlled valve is provided on the input pipeline, and an output electrically controlled valve is provided on the output pipeline.

[0009] Compared with the prior art, the beneficial effect of the present invention is that before the traditional lubricating oil recovery method of directly treating the lubricating oil through a vacuum oil filter, a recovery and water removal device is set to pre-treat the oil to remove water, thereby removing a large amount of water mixed in during actual use, reducing the working pressure of the vacuum oil filter, and ensuring the filtering treatment effect of the vacuum oil filter on the oil.

[0018] When in use, the oil is input into the interior of the processing tank body 1 through the input pipe 2, and a guide cover 7 is set at the position corresponding to the input pipe 2 inside the processing tank body 1 to guide the oil to avoid turbulence of the oil in the processing tank body 1 caused by the impact of the oil. The oil settles inside the processing tank body 1, and the water settles at the lower end of the interior of the processing tank body 1. An observation window 8 is set on the side wall of the processing tank body 1 to observe the water level. When the water level is high, the water is discharged to the outside through the discharge pipe 9, and the oil floats on the surface of the interior of the processing tank body 1 At the end, the dehydrated oil is output to the outside through the output pipe 3, and the output oil flows to the vacuum oil filter for fine water removal. An upper liquid level sensor 4 and a lower liquid level sensor 5 are respectively provided inside the processing tank body 1. The upper liquid level sensor 4 and the lower liquid level sensor 5 are used to monitor the oil level at the output pipe 3 in real time to ensure that the oil level is maintained between the upper liquid level sensor 4 and the lower liquid level sensor 5, and a pressure relief valve 6 is provided at the upper end of the processing tank body 1 to release the pressure inside the processing tank body 1.

[0019] The processing tank body 1 has a hollow cylindrical structure. The upper and lower ends of the processing tank body 1 are respectively connected to the top cover 10 and the bottom cover 11 through flange sealing. The upper liquid level sensor 4, the lower liquid level sensor 5 and the pressure relief valve 6 are set on the top cover 10 through threaded sealing. The discharge pipe 9 is connected to the middle position of the lower end of the bottom cover 11. By respectively arranging the top cover 10 and the bottom cover 11 at the upper and lower ends of the processing tank body 1, the upper and lower ends of the processing tank body 1 are sealed, and the upper liquid level sensor 4, the lower liquid level sensor 5 and the pressure relief valve 6 are set to the upper end of the processing tank body 1 through the top cover 10, and the discharge pipe 9 is connected to the lower end of the processing tank body 1 through the bottom cover 11.

[0021] A funnel-shaped structure is formed between the lower end of the bottom cover 11 and the discharge pipe 9. A manual valve 12 is provided on the discharge pipe 9. The funnel-shaped structure of the bottom cover 11 ensures that water can be smoothly discharged through the bottom cover 11 and the discharge pipe 9. The manual valve 12 is provided on the discharge pipe 9. When the water level is high and the water reserve is large, the manual valve 12 is opened and the water is discharged to the outside through the discharge pipe 9.

[0022] An input electric-controlled valve 13 is provided on the input pipeline 2, and an output electric-controlled valve 14 is provided on the output pipeline 3. The oil level at the position of the output pipeline 3 is monitored in real time by the upper liquid level sensor 4 and the lower liquid level sensor 5.
