[0002] Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts.

[0018] The present invention provides a lubricating oil recovery and purification device for a lubricating system, which has the following beneficial effects:

[0019] 1. The lubricating oil recovery and purification equipment of the lubrication system, by activating the unidirectional rotation movement of the stepper motor, uses the rotating blades to form a spiral downward pushing hydraulic pressure between the V-shaped coarse filter plate and the top cover, to spirally promote the filtering process of the lubricating liquid between the top cover and the V-shaped coarse filter plate, and accelerate the efficiency of the emulsion passing through the V-shaped coarse filter plate; at the same time, the V-shaped guide structure of the V-shaped coarse filter plate and the structural design of the concave top on the inner side of the top cover are used to provide a certain activity space for the lubricating oil, and timely limit the movement height of the lubricating oil upward on the inner side of the tank body, forcing the lubricating oil to continuously collide and impact with the top of the V-shaped coarse filter plate during the period of being unidirectionally spirally stirred and pushed by the rotating blades in a limited space, and the collision and pushing of the lubricating oil itself are used to avoid the accumulation or blockage of waste residue on the top side of the V-shaped coarse filter plate, which can effectively avoid the large-area blockage of the V-shaped coarse filter plate during long-term use, ensure the effective filtering cycle of the V-shaped coarse filter plate, extend the cycle of manual cleaning and maintenance of the V-shaped coarse filter plate, and also indirectly extend the service life of the V-shaped coarse filter plate.

[0020] 2. The lubricating oil recovery and purification equipment of the lubrication system can use the rotating blades with positive and negative periodic rotation to offset the direct impact of the lubricating oil on the V-shaped coarse filter plate, and at the same time evenly guide the lubricating oil to every place on the top of the V-shaped coarse filter plate, so that every filter hole on the top of the V-shaped coarse filter plate is effectively used, and there will be no local idle phenomenon. At the same time, it also avoids the concentrated accumulation of waste residue when the lubricating oil is directly poured on the V-shaped coarse filter plate, and weakens the wear intensity of the V-shaped coarse filter plate itself when the waste residue is collected and intercepted on the V-shaped coarse filter plate.

[0021] 3. The lubricating oil recovery and purification equipment of the lubrication system can effectively combine the V-shaped structural design of the V-shaped coarse filter plate itself, and use its own inclined structure to weaken the impact and destructive strength of the lubricating oil and waste residue on the V-shaped coarse filter plate, and avoid the conventional horizontal disc filter structure, which directly intercepts and filters the lubricating oil and causes the structural problem of the downward concave deformation of the middle part. At the same time, combined with the curved rail and the rounded corner processing design on the top of the V-shaped coarse filter plate, it not only further weakens the direct impact and scratches of the lubricating oil and waste residue on the surface of the V-shaped coarse filter plate, but also effectively eliminates the dead corners where the waste residue hides, and eliminates the residual hidden dangers during the subsequent cleaning of the waste residue on the top of the V-shaped coarse filter plate, ensuring that the waste residue can eventually be guided and gathered to the middle of the top of the V-shaped coarse filter plate, and then cleaned up by the subsequent scraper.

[0022] 4. The lubricating oil recovery and purification equipment of the lubrication system uses an inverted V-fine filter plate to cooperate with a V-shaped coarse filter plate to complete the second filtration of the lubricating oil, and can use the rotation of the filter component as a whole inside the tank body. The throwing force generated by this circular rotation can effectively collect the waste residue intercepted between the inverted V-fine filter plate and the V-shaped coarse filter plate in the ball recess. Even if there is residual waste residue retained on the inverted V-fine filter plate, the filter component can be driven to switch forward and reverse rotation within a small angle range by activating a stepper motor alone to swing the counterweight ball to impact the ball recess, and the impact force is transmitted to the inverted V-fine filter plate. Under the premise of no contact and no disassembly of the purification equipment, the waste residue retained on the inverted V-fine filter plate can be collected into the ball recess autonomously. At the same time, the filter holes on the surface of the inverted V-fine filter plate can be cleared by using the counterweight ball to impact the ball recess.

[0023] 5. The lubricating oil recovery and purification equipment of the lubricating system guides the lubricating oil to the bucket plate in a circular distribution evenly through the umbrella top piece. This annular curved surface guiding method can effectively further eliminate the impact and wear of the lubricating oil on the structural parts during the filtration period. At the same time, it can also complete the final fine filtration of the lubricating oil under the continuous guidance and cooperation of the grinding part, the fine filter ring and the fine filter plate, and retain the tiny debris in the lubricating oil in the closed space formed by the bucket plate, the fine filter plate, the inverted V fine filter plate and the tank body. At the same time, the fine filtration of the lubricating oil is finely divided into three levels in structure to avoid In order to prevent fine waste residue from clogging the fine filter disc at once, the last small-sized waste residue is retained and intercepted on the frosting part, fine filter mesh ring and fine filter disc respectively, to ensure that the fine filter component can filter the lubricating oil cleanly, while avoiding the load of waste residue involved in purifying the lubricating oil by a single fine filter structure alone. The workload is divided step by step to ensure the premise of filtering and purifying the lubricating oil cleanly, and it can also effectively expand and extend the effective fine filtration period of the fine filter component, avoiding the need for frequent disassembly of the equipment by staff, and avoiding the need for complex maintenance operations for the equipment to clean and maintain each filter structure by staff.

[0024] 6. The lubricating oil recovery and purification equipment of the lubrication system, through the ball ear component, the filter component and the fine filter component, the three structures adopt a curved or rounded structure design as a whole, under the premise of no internal angles and dead corners, jointly realize the step-by-step buffering and filtration treatment of the lubricating oil, and divide the waste residue into different particle sizes and intercept them on the corresponding structures. At the same time, the waste residue is automatically collected together to facilitate the subsequent waste residue export, and at the same time, the dead corners of waste residue hiding in the internal structure of the equipment are effectively eliminated. While realizing the purification equipment's thorough filtering and purification function for the lubricating oil, it provides a purification equipment that can be easily flushed and maintained, without worrying about waste residue hiding inside the equipment, resulting in unclean and incomplete cleaning, thereby improving the overall practicality of the purification equipment during use and maintenance and the convenience of cleaning.

[0025] 7. The lubricating oil recovery and purification equipment of the lubrication system, by activating the stepper motor to drive the filter component to rotate counterclockwise, and by simultaneously activating the electromagnetic lock to release the multi-tooth tongue from the inclined hole, utilizes the engagement of the multi-tooth tongue and the tooth groove to intercept the filter component as a whole inside the tank body, as shown in the structural position in the figure, figure or figure; that is, at this time, the ball recess, the ball bucket and the hemispherical cover are together surrounded to form a spherical shell structure lacking a quarter corner. At this time, the servo motor can be activated to drive the scraper to rotate counterclockwise at a flat angle, and the scraper can be used to scrape the waste residue inside the ball recess and clean it into the bottom bucket, and the scraper can be used to cooperate with the hoop frame to close the inside of the tank body again. Through the above operation, the equipment can realize the contactless automatic removal function of the waste residue.

[0026] 8. The lubricating oil recovery and purification equipment of the lubrication system can be used as a convenient inspection window for partial disassembly of the equipment and inspection of the wear and blockage of the internal structure by opening the hemispherical cover separately, so that the user can conduct a close inspection of the internal structural components of the equipment when the military equipment is dismantled as a whole.

[0057] A right-angle frame is fixedly installed on the outer surface of the tank body 1, and a servo motor 37 is fixedly installed on the right-angle frame. The servo motor 37 is installed on one side of the ball bucket 31 through the right-angle frame. Two short rods are fixedly connected to the sides of the scraper 34 in a centrally symmetrical shape. A buckle is fixedly installed in the middle between the ball bucket 31 and the hoop frame 33, and the short rod is inserted in the buckle. The short rod on the side of the scraper 34 close to the servo motor 37 is connected to the output end pin of the servo motor 37. The scraper 34 is rotatably installed with the ball bucket 31 through the cooperation of the short rod and the servo motor 37, and the ball recess 46, the ball bucket 31 and the hemispherical cover 32 are together surrounded by a spherical shell structure lacking a quarter corner, and the scraper 34 is rotatably installed with the ball recess 46 through the servo motor 37.

[0058] When in use, the stepper motor 13 is activated to drive the shaft 6 to perform periodic rotation in the clockwise and counterclockwise directions, and the shaft 6 drives the rotating blade 15 and the filter assembly 4 to perform synchronous rotation inside the tank body 1, and the lubricating oil is transported to the inside of the tank body 1 through the top cover 12 through the inlet pipe; under the diversion effect of the rotating blade 15, the lubricating oil passes through the V-shaped coarse filter plate 41 and the inverted V-shaped fine filter plate 45 in turn, and flows down the circular dispersion drainage of the umbrella top member 71 to the side of the bucket plate 51 that contacts the tank body 1. The lubricating oil is generally distributed in a circular ring shape on the bucket plate 51, and then is filtered and guided by the frosting part 50, the fine filter ring 52 and the fine filter plate 53 in turn, and finally enters the bottom tank 2 for collection. The cleanly filtered lubricating oil can finally be discharged through the outlet pipe for recycling and use.

[0059] During use, the one-way rotation of the stepper motor 13 can be used to form a spiral downward pushing hydraulic pressure between the V-shaped coarse filter plate 41 and the top cover 12 by using the rotating blade 15, so as to spirally promote the filtering process of the lubricating liquid between the top cover 12 and the V-shaped coarse filter plate 41, thereby accelerating the efficiency of the emulsion passing through the V-shaped coarse filter plate 41; at the same time, the V-shaped guide structure of the V-shaped coarse filter plate 41 and the structural design of the concave top 14 on the inner side of the top cover 12 provide a certain activity space for the lubricating oil, and timely limit the movement height of the lubricating oil upward on the inner side of the tank body 1, forcing the lubricating oil to be unidirectionally spirally moved by the rotating blade 15 in a limited space. During the stirring and boosting period, it can continuously collide and impact with the top of the V-shaped coarse filter plate 41, and use the collision and pushing of the lubricating oil itself to avoid the accumulation or blockage of waste residues on the top side of the V-shaped coarse filter plate 41, which can effectively avoid large-area blockage of the V-shaped coarse filter plate 41 during long-term use, ensure the effective filtration cycle of the V-shaped coarse filter plate 41, extend the cycle of manual cleaning and maintenance of the V-shaped coarse filter plate 41, and also indirectly extend the service life of the V-shaped coarse filter plate 41; at the same time, it is convenient to guide the waste residue intercepted on the V-shaped coarse filter plate 41 to be retained in the rounded corners at the top of the V-shaped coarse filter plate 41, so as to facilitate the subsequent waste residue discharge and processing.

[0060] During the introduction of the lubricating oil, the rotating blades 15 with positive and reverse periodic rotational motion can be used to offset the direct impact of the lubricating oil on the V-shaped coarse filter plate 41, and at the same time, the lubricating oil is evenly guided to each location on the top of the V-shaped coarse filter plate 41, so that each filter hole on the top of the V-shaped coarse filter plate 41 is effectively used, and there will be no local idleness. At the same time, it also avoids the concentrated accumulation of waste residue when the lubricating oil is directly poured on the V-shaped coarse filter plate 41, and weakens the wear intensity of the V-shaped coarse filter plate 41 itself when the waste residue is collected and intercepted on the V-shaped coarse filter plate 41.

[0061] Secondly, it can also effectively combine the V-shaped structural design of the V-shaped coarse filter plate 41 itself, and utilize its own inclined surface structure to weaken the impact and destructive strength of lubricating oil and waste residue on the V-shaped coarse filter plate 41, and avoid the conventional horizontal disc filter structure, and the structural problem of the downward concave deformation of the middle part caused by the direct interception and filtration of the lubricating oil. At the same time, combined with the rounded processing design of the curved rail 43 and the top of the V-shaped coarse filter plate 41, it not only further weakens the direct impact and scratches of lubricating oil and waste residue on the surface of the V-shaped coarse filter plate 41, but also effectively eliminates the dead corners for the hiding of waste residue, and eliminates the residual hidden dangers during the subsequent cleaning of the waste residue on the top of the V-shaped coarse filter plate 41, ensuring that the waste residue can eventually be guided and gathered to the middle of the top of the V-shaped coarse filter plate 41, and then cleaned up by the subsequent scraper block 65.

[0062] The inverted V-shaped fine filter plate 45 is used in conjunction with the V-shaped coarse filter plate 41 to complete the second filtering of the lubricating oil, and the filter assembly 4 can rotate as a whole inside the tank body 1. The swinging force generated by this circular rotation can effectively collect the waste residue intercepted between the inverted V-shaped fine filter plate 45 and the V-shaped coarse filter plate 41 in the ball recess 46. Even if there is residual waste residue retained on the inverted V-shaped fine filter plate 45, the filter assembly 4 can be driven to rotate forward and reverse within a small angle range by activating the stepper motor 13 alone to swing the counterweight ball 47 to impact the ball recess 46, and the impact force is transmitted to the inverted V-shaped fine filter plate 45. Under the premise of no contact and no disassembly of the purification equipment, the waste residue retained on the inverted V-shaped fine filter plate 45 can be collected into the ball recess 46 autonomously. At the same time, the filter holes on the surface of the inverted V-shaped fine filter plate 45 can be cleared by using the counterweight ball 47 to impact the ball recess 46.

[0063] The lubricating oil is evenly guided to the bucket plate 51 in a circular distribution through the umbrella top member 71. This annular curved surface guiding method can effectively further eliminate the impact and wear of the lubricating oil on the structural components during the filtration period. At the same time, the final fine filtration of the lubricating oil can be completed under the continuous guidance and cooperation of the frosting part 50, the fine filter ring 52 and the fine filter plate 53. The tiny debris in the lubricating oil is retained in the closed space formed by the bucket plate 51, the fine filter plate 53, the inverted V fine filter plate 45 and the tank body 1. At the same time, the fine filtration of the lubricating oil is finely divided into three levels in structure to avoid fine waste residues. While blocking the fine filter disc 53 all at once, the last small-sized waste residues are retained and intercepted on the frosting part 50, the fine filter mesh ring 52 and the fine filter disc 53 respectively, ensuring that the fine filter component 5 can filter the lubricating oil cleanly while avoiding the load of the waste residues involved in the single fine filter structure to purify the lubricating oil alone. The workload is divided step by step to ensure the premise of filtering and purifying the lubricating oil cleanly, and it can also effectively expand and extend the effective fine filtration use period of the fine filter component 5, avoiding the need for frequent disassembly of the equipment by the staff, and avoiding the need for the equipment to require the staff to clean and maintain each filter structure. Complex maintenance operations.

[0064] Through the ball ear component 3, the filter component 4 and the fine filter component 5, the three structures as a whole adopt a curved surface or rounded corner structure design, which together realizes the step-by-step buffering and filtering treatment of the lubricating oil without internal corners and dead corners. The waste residues are divided into different particle sizes and intercepted on the corresponding structures. At the same time, the waste residues are automatically collected together to facilitate the subsequent waste residue export. At the same time, the dead corners for hiding waste residues in the internal structure of the equipment are also effectively eliminated. While realizing the thorough filtering and purification function of the purification equipment for the lubricating oil, a purification equipment that can be easily flushed and maintained is provided, and there is no need to worry about the waste residues hiding inside the equipment, resulting in unclean and incomplete cleaning, thereby improving the overall practicality of the purification equipment during use and maintenance and the convenience of cleaning.

[0065] The second embodiment is based on the first embodiment. Fig.10 , Figure 12 to Figure 13 As shown, two combined slats 61 are telescopically installed in the middle of the inner side of the shaft rod 6, and an electric push rod 64 is hinged at the top of the combined slats 61. The two combined slats 61 are together accommodated on the inner side of the shaft rod 6 through the electric push rod 64. A pin head 62 is threadedly installed on the top of the shaft rod 6. The electric push rod 64 is assembled in the shaft rod 6 through the pin head 62. A sleeve 63 is fixedly installed on the outer surface of the shaft rod 6. The rotating blade 15 is threadedly installed with the shaft rod 6 through the sleeve 63 and the screw rod. A scraper block 65 is hinged at the bottom end of the combined slat 61, and the bottom of the scraper block 65 is fitted in the middle of the top of the V-shaped coarse filter plate 41, wherein the scraper plate 34 is also used to cooperate with the scraper block 65 to introduce the waste residue in the rounded corner of the middle of the top of the V-shaped coarse filter plate 41 into the bottom bucket 35.

[0066] The glass 11 and the hemispherical cover 32 can be used to conveniently observe the accumulation of waste residue inside the tank body 1. After the use of the equipment is finished, that is, after the lubricating oil is discharged from the outlet pipe; first, the filter assembly 4 is driven to rotate counterclockwise by activating the stepper motor 13, so that the end of the chamfered portion of the top middle part of the V-shaped coarse filter plate 41 and the ball center where the ball bucket 31 is located are in the same vertical plane, such as Fig.15 As shown in the position;

[0067] At this time, the servo motor 37 is first activated to drive the scraper 34 to turn clockwise inside the hoop frame 33, so that the bottom of the scraper 34 is pressed against the bottom of the inverted V fine filter plate 45, and the inverted V fine filter plate 45 is clamped inside the tank body 1. At the same time, the scraper 34 connects the V-shaped coarse filter plate 41 and the ball bucket 31; then the electric push rod 64 is activated to extend downward to push the two combined strips 61 out of the shaft rod 1 6. During the pushing process, the scraper blocks 65 at the bottom of the two combined strips 61 are pushed toward both ends along the rounded structure at the top of the V-shaped coarse filter plate 41, and the waste residue on the V-shaped coarse filter plate 41 is guided by the scraper 34 and collected in the bottom bucket 35;

[0068] Then, the ball ear assembly 3 and the filter assembly 4 are restored to their initial state. Figure 2 Then, the filter assembly 4 is driven to rotate counterclockwise by activating the stepper motor 13, and the multi-tooth tongue 49 is released from the inclined hole by activating the electromagnetic lock 48 at the same time, so as to utilize the engagement between the multi-tooth tongue 49 and the tooth groove 17 to stop the filter assembly 4 as a whole inside the tank body 1, as shown in FIG. Figure 2 , Figure 4 or Figure 7The structural position is shown in the figure; that is, the ball recess 46, the ball bucket 31 and the hemispherical cover 32 are together surrounded by a spherical shell structure lacking a quarter corner. At this time, the servo motor 37 can be enabled to drive the scraper 34 to rotate counterclockwise by a flat angle, and the scraper 34 is used to scrape the waste residue inside the ball recess 46 and clean it into the bottom bucket 35, and the scraper 34 is used to cooperate with the hoop frame 33 to close the inside of the tank body 1 again. Through the above operation, the equipment realizes the contactless automatic removal function of the waste residue.

[0069] The small particles of waste stored on the fine filter component 5 can be cleaned separately during the subsequent regular disassembly of the equipment to clean and maintain the structure; during the above cleaning of the waste inside the equipment, the hemispherical cover 32 is always closed and assembled on the ball bucket 31, and the inside of the tank will not be polluted by the external environment during the removal of the waste. After the equipment is shut down and the lubricating oil is drained, the hemispherical cover 32 can be opened separately to serve as a convenient inspection window for partial disassembly of the equipment and viewing the wear and blockage of the internal structure, so that the user can achieve close inspection of the internal structural components of the equipment when the military equipment is dismantled as a whole.
