Abstract

This invention relates to the field of lubricating oil regeneration and purification technology, and discloses an industrial lubricating oil regeneration and purification device. The device includes a vacuum tank, with a motor frame fixedly connected to the bottom of the vacuum tank. A servo motor is mounted on the bottom of the motor frame, and a bevel gear is fixedly connected to the output end of the servo motor.

Description

Technical Field

[0001] This invention relates to the field of lubricating oil regeneration and purification technology, specifically to an industrial lubricating oil regeneration and purification device. Background Technology

[0002] Industrial lubricating oil regeneration and purification equipment is a device that purifies and regenerates deteriorated and scrapped industrial lubricating oil. It removes harmful components such as water, impurities, acidic substances, and oxides from waste oil through a series of physical or chemical technical means, allowing the oil's performance to reach or approach the standards of new oil, thereby achieving recycling.

[0003] In existing industrial lubricating oil regeneration and purification equipment, during water-oil separation, the oil is sent into a vacuum separation tank in a high-vacuum environment. The oil is dispersed into an extremely thin oil film or fine oil mist by spraying or special fillers, which instantly expands the contact area by hundreds of times. Under the high vacuum and low temperature heating environment of about 60°C, the boiling point of water will be greatly reduced, and the dissolved water in the oil will quickly vaporize and evaporate, turning into water vapor which is extracted by the vacuum pump. This process will not damage the oil quality due to high temperature.

[0004] The inventors of this application discovered in their research that the core defect of the aforementioned prior art is that: because it is necessary to atomize and spray the oil inside the vacuum tank, so that the oil separated from the water vapor adheres to the inside of the vacuum tank and flows slowly along the inner wall of the vacuum tank, this process takes a long time, and the oil is very likely to adhere to the inner wall of the vacuum tank for a long time, affecting the subsequent oil purification. Summary of the Invention

[0005] This invention provides an industrial lubricating oil regeneration and purification device that solves the problem that oil can only flow slowly down the inner wall of a vacuum tank, thereby increasing the working efficiency of the industrial lubricating oil regeneration and purification device.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an industrial lubricating oil regeneration and purification device, comprising a vacuum tank, a motor frame fixedly connected to the bottom of the vacuum tank, a servo motor mounted on the bottom of the motor frame, a bevel gear one fixedly connected to the output end of the servo motor, a hollow tube rotatably connected inside the vacuum tank, a bevel gear two fixedly connected to the bottom of the hollow tube, a transmission bevel gear rotatably connected to the top of the motor frame, the transmission bevel gear meshing with bevel gear one and bevel gear two respectively, a water inlet groove being provided at the bottom of the hollow tube, an auxiliary frame fixedly connected to the outside of the hollow tube, a guide rod fixedly connected inside the auxiliary frame, an inner sliding rod slidably connected to the outside of the guide rod, the inner sliding rod slidably connected inside the auxiliary frame, a spring two fixedly connected to one end of the inner sliding rod through the inside of the auxiliary frame, and a wall scraping rod fixedly connected to the other end of the inner sliding rod, the wall scraping rod abutting against the inside of the vacuum tank.

[0007] By adopting the above technical solution, the servo motor drives the scraper to rotate inside the vacuum tank, and the spring guide structure achieves adaptive contact, effectively scraping off the oil adhering to the inner wall. This design can shorten the oil adhesion cycle, improve the regeneration and purification efficiency, and optimize the subsequent cleaning process, overcoming the drawback of the existing technology where the oil flows down naturally by gravity.

[0008] Preferably, a hollow block is fixedly connected to the bottom of the vacuum tank, the hollow block is rotatably connected to the outside of the water inlet tank, a three-way valve is connected to one end of the hollow block, a telescopic rod is fixedly connected to the inside of the hollow tube, a piston head is fixedly connected to the bottom of the telescopic rod, the piston head is slidably connected to the inside of the hollow tube, a flow groove is opened on the outside of the piston head, a spring is fixedly connected to the top of the piston head through the inside of the hollow tube, and a liquid nozzle is connected to the outside of the hollow tube.

[0009] Preferably, an atomizing nozzle is fixedly connected to the top of the hollow tube, a locking head is fixedly connected to the top of the vacuum tank, the locking head is rotatably connected to the top of the atomizing nozzle, a pre-flow chamber is connected to the top of the locking head, and an oil pipe is connected to the top of the pre-flow chamber.

[0010] Preferably, the locking head is internally fixedly connected to a guide rail, the top of the atomizing nozzle is fixedly connected to a bottom block, the top of the bottom block is fixedly connected to a ratchet, and the bottom block is internally fixedly connected to an auxiliary rod.

[0011] Preferably, a piston rod is slidably connected to the outside of the auxiliary rod, the piston rod is slidably connected to the inside of the bottom block, and a ratchet is fixedly connected to the outside of the piston rod.

[0012] Preferably, the auxiliary rod is fixedly connected to a telescopic rod II through the inside of the piston rod, and the auxiliary rod is fixedly connected to a tension spring through the inside of the piston rod.

[0013] Preferably, a piston plate is fixedly connected to the top of the piston rod, and an external block is fixedly connected to the outside of the piston rod, with the external block slidably connected inside the external block.

[0014] Preferably, a mixing rod is fixedly connected to the top of the first bevel gear, the mixing rod passes through the second bevel gear and the hollow tube, the hollow tube is rotatably connected to the mixing rod, and a gear ring is fixedly connected inside the hollow tube.

[0015] Preferably, a mixing frame is fixedly connected to the outside of the mixing rod, a rotating shaft is rotatably connected between the mixing frames, a mixing blade is fixedly connected to the outside of the rotating shaft, and a planetary gear is fixedly connected to the outside of the mixing blade, the planetary gear meshing inside the gear ring.

[0016] Preferably, the top of the vacuum tank is connected to a water vapor pipe, and the top of the vacuum tank is connected to a vacuum extraction pipe.

[0017] By adopting the above technical solution, during cleaning, the three-way valve introduces the cleaning fluid, which rises along the hollow tube. The piston head is hydraulically lifted, allowing the fluid to be sprayed out from the rotating nozzle through the flow channel. This, combined with the scraper rod, achieves efficient cleaning inside the tank. When the machine stops, the piston head automatically seals the connection position, effectively preventing oil and gas intrusion and solving the problem of inconvenient cleaning of traditional equipment.

[0018] This invention provides an industrial lubricating oil regeneration and purification device. It has the following beneficial effects:

[0019] 1. This invention uses a servo motor to drive the hollow tube to rotate inside the vacuum tank, causing the scraper rod to scrape across the inside of the vacuum tank. Combined with a spring and guide rod structure, this allows the scraper rod to better and more fully adhere to the inner wall of the vacuum tank, enabling it to scrape away the oil adhering to the inner wall downwards. This reduces the oil's adhesion time inside the vacuum tank, increases the working efficiency of the industrial lubricating oil regeneration and purification equipment, and, in conjunction with subsequent vacuum tank cleaning processes, improves the cleaning efficiency of the vacuum tank. This solves the problem in traditional industrial lubricating oil regeneration and purification equipment where, after oil is sprayed, it can only slowly flow down the inner wall of the vacuum tank.

[0020] 2. This invention features a rotating inlet tank inside a hollow block, connected to a three-way valve for cleaning liquid. After the clean water or cleaning liquid enters the hollow block, it rises along the hollow tube to its highest point. Due to the liquid pressure, the piston head rises as a whole. The hollow tube connects to the liquid nozzle via a flow channel, and the liquid is sprayed out from the nozzle. This, combined with the rotating hollow tube and scraper, effectively cleans the inside of the vacuum tank. Furthermore, when not cleaning, the piston head remains in contact with the connection between the liquid nozzle and the hollow tube, preventing oil and gas from entering the hollow tube through the pores. This solves the problem of inconvenient internal cleaning in traditional industrial lubricating oil regeneration and purification equipment.

[0021] 3. This invention, by setting an atomizing nozzle, allows the oil to enter the vacuum tank along the locking head, so that the oil is in a low-temperature vacuum environment in an atomized state. Affected by the low-temperature vacuum environment, the oil undergoes demulsification, and water vapor evaporates in the low-temperature environment. The water vapor is discharged along the water vapor pipe connected to the vacuum pump. Furthermore, a ratchet structure is set so that when the atomizing nozzle rotates, the piston plate rises as a whole, and the oil enters the atomizing nozzle along the locking head and is sprayed out. This further ensures that the oil flows smoothly only when the equipment is running, effectively preventing the mis-discharge of oil and gas when the equipment is not running.

[0022] 4. This invention uses a servo motor to drive multiple bevel gears, causing the hollow tube and mixing rod to rotate in opposite directions. At the same time, the planetary gears rotate inside the gear ring, allowing the mixing blades to fully stir the cleaning liquid and purified water inside the hollow tube. This increases the mixing effect of the cleaning liquid and purified water and avoids the problem of poor cleaning effect caused by uneven distribution of cleaning liquid during subsequent cleaning processes.

[0034] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see the appendix Figure 1 -Appendix Figure 10 This invention provides an industrial lubricating oil regeneration and purification device, including a vacuum tank 1. A motor frame 4 is fixedly connected to the bottom of the vacuum tank 1. A servo motor 5 is installed at the bottom of the motor frame 4. A bevel gear 36 is fixedly connected to the output end of the servo motor 5. A hollow tube 7 is rotatably connected inside the vacuum tank 1. A bevel gear 37 is fixedly connected to the bottom of the hollow tube 7. A transmission bevel gear 38 is rotatably connected to the top of the motor frame 4. The transmission bevel gear 38 meshes with both bevel gear 36 and bevel gear 37. A water inlet groove 32 is provided at the bottom of the hollow tube 7. An auxiliary frame 8 is fixedly connected to the outside of the hollow tube 7. A guide rod 29 is fixedly connected to the inside of the auxiliary frame 8. An inner slide rod 9 is slidably connected to the outside of the guide rod 29. The inner slide rod 9 is slidably connected inside the auxiliary frame 8. A spring 30 is fixedly connected to one end of the inner slide rod 9 through the inside of the auxiliary frame 8. A wall scraping rod 10 is fixedly connected to the other end of the inner slide rod 9. The wall scraping rod 10 abuts against the inside of the vacuum tank 1.

[0036] Specifically, the vacuum tank 1 is always in a high vacuum low temperature environment, and its internal temperature is maintained at about 60°C. After the atomized oil enters the vacuum tank 1, the water remaining in the oil will quickly vaporize and the oil will be sprayed onto the inner wall of the vacuum tank 1. The servo motor 5 continuously supplies power, so that the servo motor 5 drives the water inlet tank 32 and the hollow tube 7 to rotate, which in turn drives the scraper rod 10 to scrape the inner wall of the vacuum tank 1. With the inclined design of the scraper rod 10, the oil flows along the scraper rod 10 to the bottom of the vacuum tank 1, which facilitates the discharge of the industrial lubricating oil regeneration and purification equipment.

[0037] During the process of scraping rod 10 abutting against the inner wall of vacuum tank 1, spring 2 30 is always under pressure, and spring 2 30 will always push inner slide rod 9, so that inner slide rod 9 always has the tendency to slide on guide rod 29, thereby pushing scraping rod 10 to fully fit against the inner wall of vacuum tank 1, while ensuring that scraping rod 10 can always fit against the inner wall of vacuum tank 1.

[0038] Please see the appendix Figure 4 and attached Figure 9A hollow block 31 is fixedly connected to the bottom of the vacuum tank 1. The hollow block 31 is rotatably connected to the outside of the water inlet tank 32. One end of the hollow block 31 is connected to a three-way valve 6. A telescopic rod 15 is fixedly connected inside the hollow tube 7. A piston head 17 is fixedly connected to the bottom of the telescopic rod 15. The piston head 17 is slidably connected inside the hollow tube 7. A flow groove 18 is opened on the outside of the piston head 17. A spring 16 is fixedly connected to the top of the piston head 17 through the inside of the hollow tube 7. A liquid nozzle 14 is connected to the outside of the hollow tube 7.

[0039] Specifically, the three-way valve 6 needs to be connected to the clean water pipe and the cleaning liquid pipe, so that after the three-way valve 6 is opened, the liquid can enter the hollow block 31. When the vacuum tank 1 needs to be cleaned, the servo motor 5 is started, and the scraper rod 10 rotates accordingly. Then, liquid is injected into the hollow tube 7 along the water inlet groove 32, and the appropriate pressure is provided for the flowing liquid so that the liquid can flow to the top of the hollow tube 7. The hydraulic pressure can push the piston head 17 to slide and rise inside the hollow tube 7. At this time, the flow groove 18 is connected to the liquid nozzle 14, and the liquid is sprayed out along the liquid nozzle 14, so that the oil- and water-loving cleaning liquid adheres to the inner wall of the vacuum tank 1. After being scraped off by the scraper rod 10, the inner wall of the vacuum tank 1 is cleaned. Then, a large amount of clean water is sprayed into the vacuum tank 1 to remove the cleaning liquid inside the vacuum tank 1, and the vacuum tank 1 is evacuated again and heated to about 60°C. The liquid is re-vaporized and discharged from the vacuum tank 1.

[0040] Please see the appendix Figure 2 , Figure 5 and attached Figure 6 The top of the hollow tube 7 is fixedly connected to an atomizing nozzle 11, and the top of the vacuum tank 1 is fixedly connected to a locking head 12. The locking head 12 is rotatably connected to the top of the atomizing nozzle 11. The top of the locking head 12 is connected to a pre-flow chamber 13, and the top of the pre-flow chamber 13 is connected to an oil pipe 2.

[0041] Atomizing nozzle 11 is fixedly connected to the top of hollow tube 7, and locking head 12 is fixedly connected to the top of vacuum tank 1. Locking head 12 is rotatably connected to the top of atomizing nozzle 11. The top of locking head 12 is connected to pre-flow chamber 13, and the top of pre-flow chamber 13 is connected to oil pipe 2. Locking head 12 controls the oil from entering the vacuum tank 1. Atomizing nozzle 11 atomizes and sprays the oil that enters the vacuum tank 1, increasing the contact area of ​​the oil and accelerating the vaporization process. Oil pipe 2 is connected to the oil storage tank after preliminary filtration, so that the oil can first flow into the pre-flow chamber 13.

[0042] The locking head 12 is fixedly connected to a guide rail 22, the top of the atomizing nozzle 11 is fixedly connected to a bottom block 19, the top of the bottom block 19 is fixedly connected to a ratchet 20, and the bottom block 19 is fixedly connected to an auxiliary rod 26. The guide rail 22 can assist the sliding of the internal structure of the locking head 12. The bottom block 19 is fixedly connected to the atomizing nozzle 11, so that when the atomizing nozzle 11 rotates, the bottom block 19 also rotates synchronously. The ratchet 20 adopts a multi-protrusion structure design, so that when the atomizing nozzle 11 rotates, the ratchet 20 also rotates synchronously inside the locking head 12.

[0043] A piston rod 24 is slidably connected to the outside of the auxiliary rod 26. The piston rod 24 is slidably connected to the inside of the bottom block 19. A ratchet 21 is fixedly connected to the outside of the piston rod 24. The rotation of the ratchet 20 will continuously push up the ratchet 21, which will cooperate with the piston rod 24 to slide outside the auxiliary rod 26.

[0044] The auxiliary rod 26 is fixedly connected to the telescopic rod 27 through the inside of the piston rod 24. The auxiliary rod 26 is fixedly connected to the tension spring 28 through the inside of the piston rod 24. The tension spring 28 plays the role of assisting the ratchet 21 in resetting.

[0045] A piston plate 25 is fixedly connected to the top of the piston rod 24, and an external block 23 is fixedly connected to the outside of the piston rod 24. The external block 23 is slidably connected inside the external block 23. The piston plate 25 will be engaged inside the pre-flow chamber 13. When the piston plate 25 is disengaged from the pre-flow chamber 13, the oil will smoothly enter the vacuum tank 1. When the piston plate 25 is in contact with the pre-flow chamber 13, the oil and gas inside the vacuum tank 1 cannot escape from the inside.

[0046] Specifically, during the process when the vacuum tank 1 is not receiving oil, the piston plate 25 remains inside the pre-flow chamber 13. At this time, the oil cannot enter the vacuum tank 1, and the oil and gas inside the vacuum tank 1 cannot flow out along the locking head 12. After the servo motor 5 is started, the atomizing nozzle 11 rotates to atomize and spray the oil. The ratchet 1 20 continuously pushes the ratchet 2 21 upward, which, together with the guide rail 22 and the external block 23, limits the movement. The piston plate 25 also disengages from the top of the pre-flow chamber 13. At this time, the oil can freely enter the vacuum tank 1. The telescopic rod 2 27 and the tension spring 28 can assist the piston plate 25 in resetting.

[0047] Please see the appendix Figure 2 , Figure 7 , Figure 9 and attached Figure 10A mixing rod 34 is fixedly connected to the top of bevel gear 36. The mixing rod 34 passes through bevel gear 37 and hollow tube 7. Hollow tube 7 is rotatably connected to mixing rod 34. A gear ring 35 is fixedly connected inside hollow tube 7. After cooperating with bevel gear transmission, hollow tube 7 and mixing rod 34 can rotate in opposite directions. After mixing rod 34 drives mixing blade 41 to rotate, the function of mixing cleaning liquid and purified water is realized.

[0048] A mixing frame 39 is fixedly connected to the outside of the mixing rod 34. A rotating shaft 40 is rotatably connected between the mixing frames 39. A mixing blade 41 is fixedly connected to the outside of the rotating shaft 40. A planetary gear 42 is fixedly connected to the outside of the mixing blade 41. The planetary gear 42 meshes inside the gear ring 35. By cooperating with the planetary gear 42 and the gear ring 35, the mixing blade 41 can rotate along the gear ring 35 while rotating on its own axis, thereby improving the mixing area and mixing efficiency.

[0049] The top of the vacuum tank 1 is connected to a water vapor pipe 3, and the top of the vacuum tank 1 is connected to a vacuum pump 33. The water vapor pipe 3 is connected to a vacuum pump, so that the water vapor separated from the oil will be discharged along the water vapor pipe 3 at the top of the vacuum tank 1.

[0050] Specifically, after the servo motor 5 is started, it drives the first bevel gear 36, which in turn rotates the transmission bevel gear 38. This causes the second bevel gear 37 to rotate in the opposite direction to the first bevel gear 36, thereby driving the hollow tube 7 and the mixing rod 34 to rotate. After the mixing rod 34 rotates, the planetary gear 42 meshes and drives inside the gear ring 35, causing the mixing blade 41 to rotate at high speed with the assistance of the mixing frame 39 using the rotating shaft 40, thus playing the role of mixing liquid. Subsequently, the mixed cleaning liquid and clean water will be sprayed out along the liquid nozzle 14.

[0051] Workflow: Vacuum tank 1 is always in a high vacuum low temperature environment, with its internal temperature maintained at around 60℃. After the atomized oil enters the vacuum tank 1, the water remaining in the oil will quickly vaporize, and the oil will be sprayed onto the inner wall of the vacuum tank 1. Servo motor 5 continuously supplies power. After the servo motor 5 starts, it drives bevel gear 36 and causes transmission bevel gear 38 to rotate, causing bevel gear 37 to rotate in the opposite direction to bevel gear 36. This drives hollow tube 7 and mixing rod 34 to rotate respectively. After the servo motor 5 drives water inlet tank 32 and hollow tube 7 to rotate, it drives scraper rod 10 to scrape the inner wall of vacuum tank 1. With the inclined design of scraper rod 10, the oil flows along scraper rod 10 to the bottom of vacuum tank 1, which facilitates the discharge of industrial lubricating oil regeneration and purification equipment.

[0052] During the process of scraping rod 10 abutting against the inner wall of vacuum tank 1, spring 2 30 is always under pressure and spring 2 30 will always push inner slide rod 9, so that inner slide rod 9 always has the tendency to slide on guide rod 29, thereby pushing scraping rod 10 to fully fit against the inner wall of vacuum tank 1, while ensuring that scraping rod 10 can always fit against the inner wall of vacuum tank 1.

[0053] The three-way valve 6 needs to be connected to both the clean water pipe and the cleaning liquid pipe, allowing the liquid to enter the hollow block 31 after the valve is opened. When the vacuum tank 1 needs cleaning, the servo motor 5 is activated, causing the scraper rod 10 to rotate and the mixing rod 34 to rotate as well. This causes the planetary gear 42 to mesh and drive within the gear ring 35, resulting in the mixing blade 41 rotating at high speed with the assistance of the mixing frame 39 and the rotating shaft 40, thus mixing the liquid. Subsequently, the liquid is injected into the hollow pipe 7 along the water inlet trough 32, providing appropriate pressure for the flowing liquid. The liquid can flow to the top of the hollow tube 7, and the hydraulic pressure can push the piston head 17 to slide and rise inside the hollow tube 7. At this time, the flow channel 18 is connected to the liquid nozzle 14, and the liquid is sprayed out along the liquid nozzle 14, so that the oil- and water-loving cleaning liquid adheres to the inner wall of the vacuum tank 1. After being scraped off by the wall scraper 10, the inner wall of the vacuum tank 1 is cleaned. Then, a large amount of clean water is sprayed into the vacuum tank 1 to remove the cleaning liquid inside the vacuum tank 1, and the vacuum tank 1 is evacuated again and heated to about 60°C. The liquid is re-vaporized and discharged from the vacuum tank 1.

[0054] During the process of not filling the vacuum tank 1 with oil, the piston plate 25 remains inside the pre-flow chamber 13. At this time, the oil cannot enter the vacuum tank 1, and the oil and gas inside the vacuum tank 1 cannot flow out along the locking head 12. After the servo motor 5 is started, the atomizing nozzle 11 rotates to atomize and spray the oil. The ratchet 1 20 continuously pushes the ratchet 2 21 to rise, which, together with the guide rail 22 and the external block 23, limits the movement. The piston plate 25 also disengages from the top of the pre-flow chamber 13. At this time, the oil can freely enter the vacuum tank 1. The telescopic rod 2 27 and the tension spring 28 can assist the piston plate 25 in resetting.
