[0027] like Figure 1-Figure 8 As shown, the utility model is a lubricating oil recovery device, including a heating treatment tank 1, a recovery tank 2, a stirring mechanism 3 and a metal separation mechanism 4.

The oil inlet pipe 6 is connected between two adjacent groups of support legs 5. The recovery tank 2 is arranged on a support rod 8; the feeding pipe 7 is connected with a sealing cover 37 by a thread.

[0028] A first solid-liquid separation chamber 9, a second solid-liquid separation chamber 10, a driving chamber 11 and a recovery chamber 12 are provided in the recovery tank 2. The first solid-liquid separation chamber 9 and the second solid-liquid separation chamber 10 are symmetrically located on the left and right sides of the driving chamber 11. The first solid-liquid separation chamber 9 and the recovery chamber 12 are connected through a first opening, and a first filter screen 18 is provided at the first opening. The second solid-liquid separation chamber 10 and the recovery chamber 12 are connected through a second opening, and a second filter screen 19 is provided at the second opening. A three-way pipe 13 is connected between the heating treatment tank 1 and the recovery tank 2. The three-way pipe 13 forms a first channel 14 and a second channel 15 between the heating treatment tank 1 and the first solid-liquid separation chamber 9 and between the heating treatment tank 1 and the second solid-liquid separation chamber 10, respectively. A first solenoid valve 16 is provided on the first channel 14, and a second solenoid valve 17 is provided on the second channel 15. The stirring mechanism 3 and the metal separation mechanism 4 are both arranged in the heating treatment tank 1; an oil outlet pipe 35 is provided on the recovery tank 2, and the oil outlet pipe 35 is connected to the recovery chamber 12, and a third solenoid valve 36 is provided on the oil outlet pipe 35.

[0029] The left and right sides of the recovery tank 2 are provided with impurity discharge ports 22, and the two groups of impurity discharge ports 22 are respectively connected to the first solid-liquid separation chamber 9 and the second solid-liquid separation chamber 10. A double-headed motor 34 is provided in the driving chamber 11, and two groups of conveying shafts 20 are respectively connected to the output ends on both sides of the double-headed motor 34. The two groups of conveying shafts 20 rotate and extend into the first solid-liquid separation chamber 9 and the second solid-liquid separation chamber 10 respectively, and a spiral conveying blade 21 is sleeved on the conveying shaft 20.

[0030] The stirring mechanism 3 includes a stirring shaft 23, a spiral stirring blade 24, a stirring paddle 25, a sleeve 26 and a connecting rod 27. The stirring shaft 23 is rotatably arranged in the heating treatment tank 1, the sleeve 26 is sleeved on the stirring shaft 23, the connecting rod 27 is arranged on the sleeve 26, the spiral stirring blade 24 is arranged on the connecting rod 27, and the stirring paddle 25 is arranged at the bottom of the stirring shaft 23; a rotating motor 33 is arranged on the heating treatment tank 1, and one end of the stirring shaft 23 is arranged on the output shaft of the rotating motor 33.

[0031] The metal separation mechanism 4 includes a mounting frame 28 and a magnetic rod 29. The mounting frame 28 is sleeved on the stirring shaft 23. A rotating seat 30 is rotatably provided on the stirring shaft 23, and the magnetic rod 29 is provided on the rotating seat 30. A gear 31 is sleeved on the rotating seat 30, and a gear ring 32 is provided in the heating treatment tank 1, and the gear 31 is meshed with the gear ring 32. There are several groups of rotating seats 30, and the several groups of rotating seats 30 are distributed in a circular array. The number of magnetic rods 29 is equal to the number of rotating seats 30 and corresponds one to one.

[0032] During specific use, the lubricating oil is introduced into the heating treatment tank 1 through the oil inlet pipe 6, and the lubricating oil treatment agent such as flocculant is added into the heating treatment tank 1 through the feeding pipe 7. The lubricating oil can be heated by the heating treatment tank 1 to ensure that the lubricating oil has good fluidity, and then the rotating motor 33 is started and the magnetic rod 29 is energized, so that the magnetic rod 29 generates magnetism, and the stirring shaft 23 is driven to rotate by the rotating motor 33, and the stirring shaft 23 drives the spiral stirring blade 24 and the stirring paddle 25 to rotate to fully mix and stir the lubricating oil and the treatment agent, thereby improving the treatment effect of the lubricating oil. When the stirring shaft 23 rotates, it will drive the mounting frame 28 to rotate, and the mounting frame 28 will drive the rotating seat 30 to rotate, and the rotating seat 30 will drive the magnetic rod 29 and the gear 31 to rotate. Since the gear 31 is meshed with the gear ring 32, the gear 31 itself will rotate when it rotates, thereby driving the magnetic rod 29 to rotate, and the magnetic rod 29 can absorb metal impurities in the lubricating oil by rotating while revolving.

[0033] After the treatment is completed, the rotating motor 33 is turned off and the double-headed motor 34 is started. The double-headed motor 34 drives the conveying shaft 20 to rotate, and the conveying shaft 20 drives the spiral conveying blade 21 to rotate. Then the first solenoid valve 16 and the third solenoid valve 36 are opened, so that the lubricating oil and non-metallic impurities in the heating treatment tank 1 enter the first solid-liquid separation chamber 9 through the first channel 14, and the lubricating oil in the first solid-liquid separation chamber 9 passes through the first filter screen 18 and enters the recovery chamber 12. The lubricating oil in the recovery chamber 12 is discharged through the oil outlet pipe 35, and the non-metallic impurities in the first solid-liquid separation chamber 9 are transported to the impurity discharge port 22 by the spiral conveying blade 21 and discharged through the impurity discharge port 22. When the metal impurities need to be discharged, the first solenoid valve 16 is closed, the second solenoid valve 17 is opened, and the power of the magnetic rod 29 is cut off, so that the magnetic force of the magnetic rod 29 disappears. At this time, the metal impurities will fall from the magnetic rod 29 and enter the second solid-liquid separation chamber 10 through the second channel 15. The metal impurities in the second solid-liquid separation chamber 10 will be transported to the impurity discharge port 22 by the spiral conveying blades 21 and discharged through the impurity discharge port 22.

[0034] In summary, the present scheme is provided with a stirring mechanism 3, through which the lubricating oil and the treatment agent can be fully mixed and stirred to improve the treatment effect of the lubricating oil; the present scheme is provided with a metal separation mechanism 4, through which the metal impurities in the lubricating oil can be conveniently separated separately; the present scheme is provided with a recovery tank 2, through which the lubricating oil, metal impurities and other non-metallic impurities can be separately recovered.
