[0015] The present invention also discloses a regeneration processing method for waste lubricating oil, which specifically includes the following steps: Step 1: Add waste lubricating oil into the filter cartridge through the inlet pipe.

Then the torsion spring rebounds, making the ratchet wheel drive the rubber rod to rotate through the clamping block, and hitting the cross bar through the rubber rod to make the discharging pipe vibrate, so as to realize vibrating discharging. Beneficial effects

[0016] The present invention provides a regeneration processing device and method for waste lubricating oil. Compared with the prior art, the following beneficial effects are achieved: (1) By setting up a processing mechanism, the viscosity of waste oil is reduced through rotary cutting and centrifugal treatment, facilitating its precipitation treatment. Moreover, when the rotary blades are magnetized and stirring the waste oil, waste chips in the waste oil can be adsorbed, realizing the filtration treatment of the waste oil, thereby improving the regeneration and processing efficiency of the waste oil.

[0017] (2) By setting up a driving component, through the meshing transmission of three planetary gears, the outer gear ring drives the rotating shaft, and the inner gear ring drives the filter cylinder to move synchronously in the opposite direction, further enhancing the rotary cutting effect on the waste oil to improve the regeneration and processing efficiency.

[0018] (3) By setting up a compression unit, when processing the waste oil, external air is compressed into the fixed sleeve synchronously, and the air temperature is increased through air compression. Then, the baffle is heated by the high-temperature air, causing the baffle to deform into a conical shape to facilitate the diversion and discharging of iron chips.

[0019] (4) By setting up a blocking component, driven by an adjustment motor and through the meshing of a bevel gear ring and bevel gears, the blades rotate to control the blocking and circulation at one end of the discharge pipe, thereby facilitating the processing of waste oil and the discharging of iron chips.

[0020] (5) By setting up a vibrating material unit, the waste oil flow causes the paddle to compress the torsion spring, and the torsion spring rebounds to make the rubber rod rotate and collide with the cross bar, causing the discharge pipe to vibrate, facilitating the discharging of iron chips and preventing the problem of iron chip accumulation and blockage.

Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figure 1-6 , the present invention provides a technical solution: a regeneration processing device for waste lubricating oil: Embodiment 1: Refer to the attached drawings of the specification Figure 1 , attached Figure 2 ; It includes a processing box 1. An oil inlet pipe 2 penetrates and communicates with the inside of the processing box 1. The oil inlet pipe 2 is used to add waste lubricating oil into the inside of the processing box 1. A processing mechanism is arranged inside the processing box 1. The processing mechanism includes a rotating shaft 3. The outer surface of the rotating shaft 3 is rotatably connected through the body of the processing box 1. A filter cylinder 7 is sleeved outside the rotating shaft 3. A rotating blade 8 penetrating through its body is arranged inside the rotating shaft 3. The rotating blade 8 is arranged at a certain inclination angle, generally the inclination angle is between 5° and 10°, which is used to cut the waste oil without causing the waste oil to splash. At the same time, one end of the rotating blade 8 is arc-shaped and is consistent with the outer surface of the rotating shaft 3. The rotating blade 8 rotates inside the filter cylinder 7 by centrifugal force. Three connecting grooves 9 are opened on the outer surface of the rotating blade 8. The inside of the connecting grooves 9 is communicated with the inside of the rotating shaft 3. Electromagnets 10 are arranged inside two of the connecting grooves 9. When the electromagnets 10 are energized, they generate magnetism to adsorb iron filings in the waste oil. A spring 11 is arranged inside one of the connecting grooves 9. One end of the spring 11 is fixedly connected to the inside of one of the connecting grooves 9. A discharge pipe 5 is communicated with the inside of the filter cylinder 7. The discharge pipe 5 is used for discharging the recovered iron filings. A baffle 12 is fixedly connected to the outer surface of the discharge pipe 5. The baffle 12 is made of shape memory metal and deforms into a conical shape when heated, so as to facilitate the diversion and discharge of the iron filings. The outer surface of the baffle 12 is fixedly connected to the inside of the filter cylinder 7. One end of the discharge pipe 5 is fixedly connected through and extends to the outside of the processing box 1 through the body of the discharge end of the processing box 1. The other end of the spring 11 is fixedly connected to a magnetic column 13. The magnetic column 13 is made of permanent magnet. By changing the magnetic pole and through the repulsion or attraction of the magnetic force with the magnetic column 13, the electromagnet 10 facilitates the stability of the rotating blade 8 at two places inside and outside the rotating shaft 3. One end of the magnetic column 13 is fixedly connected to the inside of the rotating shaft 3. Pin rods 14 are slidably connected to the inside of two of the connecting grooves 9. The pin rods 14 play a role in guiding and limiting the movement of the rotating blade 8. One end of each of the two pin rods 14 is fixedly connected to the inside of the rotating shaft 3. Slip rings 15 are slidably connected to the outer surfaces of the two pin rods 14. One end of the slip ring 15 and the pin rod 14 are both made of conductive elements, and the slip ring 15 is electrically connected to the electromagnet 10. One end of the pin rod 14 can be electrically connected to an external control circuit through a rotating power connection method such as a brush. As a preferred method, a sliding damping can be set between the slip ring 15 and the pin rod 14 to improve the smoothness of the movement of the rotating blade 8. The outer surfaces of the two slip rings 15 are respectively fixedly connected to the inside of two of the connecting grooves 9.

[0025] In this embodiment, external waste lubricating oil is added into the interior of the filter cartridge 7 through the inlet pipe 2. Then, as the rotating shaft 3 rotates, the rotating blades 8 are subjected to centrifugal force and slide out from the interior of the rotating shaft 3, stretching the spring 11. At the same time, they rotate with the rotating shaft 3 to perform rotary cutting and stirring on the waste oil, thereby reducing the viscosity of the waste oil. As a result, the waste oil passes through the filter holes of the filter cartridge 7 into the interior of the processing tank 1 and is discharged into the precipitation end for precipitation treatment. Meanwhile, the electromagnet 10 is energized to generate magnetism. On the one hand, the electromagnet 10 maintains the stability of the rotating blade 8 through the magnetic force interaction with the magnetic column 13. On the other hand, the rotating blade 8 is magnetized to adsorb iron filings in the waste oil. After the processing is completed, the rotating shaft 3 stops rotating, and the spring 11 rebounds to drive the rotating blade 8 to reset. At the same time, the electromagnet 10 maintains the stability of the rotating blade 8 after reset through the magnetic attraction with the magnetic column 13. Then, the electromagnet 10 is powered off to demagnetize the rotating blade 8, so that the iron filings completely fall into the interior of the filter cartridge 7.

[0026] Embodiment Two: On the basis of Embodiment One, referring to the attached drawings of the specification Figure 1 and the attached Figure 3 ; A driving assembly 4 is arranged on the outer surface of the rotating shaft 3.

The outer surface of the driving motor 42 is fixedly connected to the interior of the processing tank 1. The outer surfaces of two of the planetary gears 41 are respectively meshed with an internal gear ring 43 and an external gear ring 44. The connection between the internal gear ring 43 and the external gear ring 44 and the planetary gears 41 enables the filter cartridge 7 and the rotating shaft 3 to move synchronously in opposite directions. The outer surface of the internal gear ring 43 is fixedly connected to the interior of the filter cartridge 7. The external gear ring 44 is fixed on the outer surface of the rotating shaft 3. A rotating ring 45 is arranged outside the internal gear ring 43. The rotating ring 45 is sleeved outside the filter cartridge 7. The inner ring of the rotating ring 45 is rotatably connected to a fixed ring 47 by embedding. The connection between the fixed ring 47 and the rotating ring 45 can improve the longitudinal stability and stress resistance of the filter cartridge 7. The inner ring of the fixed ring 47 is fixedly connected to the outer surface of the filter cartridge 7. The outer surface of the rotating ring 45 is fixedly connected to a lifting rod 48. The lifting rod 48 is made of an electric push rod and is electrically connected to an external control circuit. The outer surface of the lifting rod 48 is fixedly connected to the interior of the processing tank 1.

[0027] In this embodiment, the driving motor 42 drives the planetary gear 41 to rotate, drives the filter cartridge 7 and the rotating shaft 3 to rotate synchronously and in opposite directions through the internal gear ring 43 and the external gear ring 44, so as to reduce the viscosity of the waste oil. At the same time, the waste oil is filtered through the filter holes of the filter cartridge 7, so that the waste oil enters the interior of the processing tank 1 and is discharged into the precipitation end through the discharge end for precipitation treatment. At the same time, through the cooperation of the fixed ring 47 and the rotating ring 45, the longitudinal stability and stress resistance of the filter cartridge 7 are improved. And when the baffle 12 is heated and deformed, the output end of the lifting rod 48 retracts to drive the filter cartridge 7 to rise synchronously.

[0028] Embodiment 3: On the basis of Embodiment 2, refer to the appended drawings of the specification Figure 1 and appended Figure 4 ; A compression unit 46 is arranged outside the rotating ring 45.

One end of the air pipe 462 runs through and communicates with the inside of the processing tank 1. A pressing plate 463 is slidably connected to the inside of the fixed sleeve 461. The pressing plate 463 is made of a heat-insulating material with compressive resistance, wear resistance and good sealing performance. A one-way valve 464 is fixedly connected through the inside of the pressing plate 463. The one-way valve 464 allows outside air to flow into the inside of the fixed sleeve 461 unidirectionally. A sliding column 465 is fixedly connected through the body of the pressing plate 463. A groove 466 is opened at one end of the sliding column 465. A ball screw 467 is fixedly connected to the inside of the groove 466.

One end of the ball screw 467 of the pressing plate 463 is fixedly connected to one end of the rotating shaft 3.

[0029] In this embodiment, when the rotating shaft 3 rotates, it drives the screw part of the ball screw 467 to rotate synchronously, so that the sliding end of the ball screw 467 drives the pressing plate 463 to reciprocate up and down through the sliding column 465, thereby compressing outside air into the inside of the fixed sleeve 461 through the one-way valve 464. The air temperature rises through the compressed air. Then when the iron filings are discharged, the electromagnetic valve on the air pipe 462 is opened, and the high-temperature and high-pressure air inside the fixed sleeve 461 is blown into the inside of the processing tank 1 through the air pipe 462, and the baffle 12 is heated to be deformed into a conical shape to guide the iron filings.

The outer surface of the bevel gear 610 is fixedly connected to the shaft end of the blade 65.

[0031] In this embodiment, when it is necessary to discharge iron filings, the adjustment motor 67 drives the bevel gear ring 69 to rotate through the fixed rod 68, and through the meshing transmission of the bevel gear ring 69 and the bevel gear 610, the blade 65 rotates to disengage from the blockage of one end of the discharge pipe 5, so that the iron filings are discharged to the outside of the processing box 1 through the discharge pipe 5. After the iron filings are discharged, the adjustment motor 67 rotates in reverse to make the blade 65 rotate and reset, and closes the discharge pipe 5 again.

[0032] Embodiment 5: On the basis of Embodiment 4, refer to the attached drawings in the specification Figure 1 and the attached Figure 6 ; An actuating unit 62 is provided on the outer part of the sleeve 61. The actuating unit 62 includes a paddle 621 which rotates in contact with the flowing waste oil. The outer surface of the paddle 621 is rotatably connected to the inside of the discharging end of the processing tank 1. The shaft end of the paddle 621 penetrates through the body of the discharging end of the processing tank 1 and extends to the outside of the processing tank 1. A ratchet 622 is fixedly connected to the shaft end of the paddle 621. A rubber rod 623 is provided on the outer surface of the ratchet 622.

A cross bar 624 is movably connected to the outer surface of the rubber rod 623. One end of the cross bar 624 is fixedly connected to the outer surface of the discharge pipe 5. A catch block 625 is fixedly connected to the outer surface of the ratchet 622. The catch block 625 and the ratchet 622 can be made of a ratchet with a sprocket on the rear wheel of a bicycle. The outer surface of the catch block 625 is fixedly connected to one end of the rubber rod 623. A catch frame 626 is movably connected to the outer surface of the catch block 625. A linear motor 627 is fixedly connected to the outer surface of the catch frame 626. The linear motor 627 is electrically connected to an external control circuit. A slide rail 628 is slidably connected to the outer surface of the linear motor 627. The outer surface of the slide rail 628 is fixedly connected to the outer surface of the discharging end of the processing tank 1. A torsion spring 629 is sleeved on the shaft end of the paddle 621. The torsion spring 629 stores energy through compression to provide driving force for the rotation of the rubber rod 623. Two ends of the torsion spring 629 are respectively fixedly connected to the ratchet 622 and the outer surface of the discharging end of the processing tank 1.

[0033] In this embodiment, the discharged waste oil contacts the paddle 621, causing the paddle 621 to compress the torsion spring 629 through the ratchet 622. When discharging iron filings, the linear motor 627 drives the catch frame 626 to move along the slide rail 628, so that the catch frame 626 disengages from the abutment against the catch block 625. Then, the torsion spring 629 rebounds to drive the overall rotation of the ratchet 622, causing the catch block 625 to drive the rubber rod 623 to rotate accordingly. The rubber rod 623 moves to impact the cross bar 624 and reciprocates through deformation. At the same time, the cross bar 624 causes the discharge pipe 5 to vibrate, facilitating the discharge of iron filings and avoiding the problem of iron filings accumulation and blockage.

[0034] The present invention also discloses a regeneration processing method for waste lubricating oil, which specifically includes the following steps: Step 1: Add waste lubricating oil into the filter cartridge 7 through the inlet pipe 2. The drive motor 42 drives the rotation of the rotating shaft 3 and the filter cartridge 7 in opposite directions and synchronously through the transmission of the planetary gear 41. The rotating blade 8 slides out under centrifugal force to cut the waste oil, reducing the viscosity of the waste oil. The iron filings and impurities in the waste oil are adsorbed by the magnetic force of the electromagnet 10. The filter cartridge 7 rotates and centrifugally throws the waste oil into the processing tank 1, and discharges it into the precipitation end through the discharging end of the processing tank 1 for precipitation treatment. The paddle 621 contacts the waste oil and compresses the torsion spring 629 through the ratchet 622; Step 2: The rotating shaft 3 rotates to make the pressing plate 463 move repeatedly through the ball screw 467, so as to press the external air into the inside of the fixed sleeve 461. After the waste oil treatment is completed, the compressed hot air inside the fixed sleeve 461 enters the inside of the processing box 1 through the air pipe 462. The baffle 12 is heated and deformed into a conical shape. Then the rotating shaft 3 stops rotating and the electromagnet 10 is powered off. The rotating blade 8 returns to its original position due to the spring 11 rebounding. At the same time, the iron filings adsorbed on the surface of the rotating blade 8 fall off, and are discharged through the diversion of the conical baffle 12; Step 3: When discharging is required, the regulating motor 67 drives the blade 65 to rotate through the transmission of the bevel gear ring 69 and the bevel gear 610 to disengage the blockage of one end of the discharge pipe 5. The iron filings are then discharged to the outside of the processing box 1 through the discharge pipe 5. At the same time, the linear motor 627 drives the rack 626 to move away from the limit of the ratchet 622. Then the torsion spring 629 rebounds, so that the ratchet 622 drives the rubber rod 623 to rotate through the block 625, and the discharge pipe 5 is vibrated by hitting the cross bar 624 with the rubber rod 623 to achieve vibrating discharge.

[0035] At the same time, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
