Description

Technical Field

[0001] This invention relates to the field of lubricating oil processing technology, and in particular to a feeding device and feeding method for lubricating oil processing. Background Technology

[0002] Lubricating oil plays a vital role in modern industry. With continuous industrial development, the demand for lubricating oil is increasing daily. Lubricating oil processing involves a series of processes such as mixing, blending, and refining base oils and various additives to produce lubricating oil products that meet the requirements of different equipment and operating conditions. In industrial production, the operation of mechanical equipment cannot be separated from good lubrication. Lubricating oil can reduce friction, reduce wear, cool equipment, and prevent corrosion, thereby extending the service life of equipment and improving production efficiency. Lubricating oil generally consists of two parts: base oil and additives. Base oil is the main component of lubricating oil, determining its basic properties, while additives can compensate for and improve the shortcomings of base oil performance, imparting certain new properties, and are an important component of lubricating oil.

[0003] For example, Chinese Patent Publication No. CN112108053A discloses an automatic feeding device for lubricating oil processing, which includes a mixing tank. A main shaft is rotatably connected inside the mixing tank. A mixing disc is movably sleeved on the outer ring of the main shaft. A mixing blade is rotatably connected inside the mixing disc. A linkage block one is movably connected to the side wall of the mixing tank. A linkage rod is fixedly connected to the outer side of the linkage block one. A raw material inlet is fixedly connected to the top of the mixing tank. A rotating disc is movably connected to the cross-sectional end of the raw material inlet. A linkage block two is fixedly connected to the outer ring of the rotating disc. An arc groove is formed on the surface of the rotating disc. A fixed disc is movably connected to the ground of the rotating disc. A fixed shaft is fixedly connected to the surface of the fixed disc. A baffle is fixedly connected to the upper end of the fixed shaft.

[0004] When the automatic feeding device for lubricating oil processing mentioned in the above application is in use, the traditional method of adding additives is to directly pour them into the stirred lubricating oil. This method is prone to generating impurities during the addition process. Furthermore, the relatively concentrated additives are difficult to mix evenly into the lubricating oil in a short time, which affects the uniform mixing efficiency. In addition, the additives poured in directly cannot be effectively filtered and need to be filtered first, which is more cumbersome and affects the overall processing efficiency.

[0005] Therefore, it is necessary to provide a feeding device and feeding method for lubricating oil processing to solve the above-mentioned technical problems. Summary of the Invention

[0006] The purpose of this invention is to provide a feeding device and feeding method for lubricating oil processing, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following solution to the above technical problems: a feeding device for lubricating oil processing, comprising a processing cylinder, a top plate fixed to the top of the processing cylinder, a filter plate fixed to the inner side wall of the processing cylinder located at the upper part of the processing cylinder, a shaft rotatably penetrating the bottom side wall of the processing cylinder, the filter plate and the top plate at the center of the processing cylinder, a plurality of ring-shaped stirring rods fixed to the side of the shaft, a feeding assembly for uniformly adding additive liquid to the filter plate for filtration, a cleaning assembly for timely removing impurities filtered out by the filter plate, and a switching assembly provided between the feeding assembly and the cleaning assembly.

[0008] As a further embodiment of the present invention, the feeding assembly includes a feeding rod fixed to the side of the shaft, the feeding rod being positioned above the filter plate, the feeding rod having an inner cavity a inside, and the bottom side of the feeding rod having a discharge hole communicating with the inner cavity a, and the discharge hole having multiple discharge holes that are equidistantly distributed.

[0009] As a further embodiment of the present invention, the shaft has a feeding groove arranged along the height direction of the shaft and communicating with the inner cavity a. The top end of the shaft has an end cavity a communicating with the feeding groove. The top end of the shaft is rotatably connected to a feed pipe through a bearing. The feed pipe is connected to the end cavity a.

[0010] As a further embodiment of the present invention, the impurity removal component includes a connecting pipe fixed to the side of the shaft, a suction plate fixed to the bottom end of the connecting pipe, an inner cavity b communicating with the connecting pipe is opened inside the suction plate, and a suction hole communicating with the inner cavity b is opened on the bottom side of the suction plate, and multiple suction holes are provided and the multiple suction holes are equidistantly distributed.

[0011] As a further embodiment of the present invention, the shaft has an air delivery groove arranged along the height direction of the shaft and connected to the connecting pipe. The bottom end of the shaft has an end cavity b connected to the air delivery groove. The bottom end of the shaft is rotatably connected to a suction pipe through a bearing. The suction pipe is connected to the end cavity b.

[0012] As a further embodiment of the present invention, the switching assembly includes a sliding adjustment rod that slides through the air conveying groove and the material conveying groove. A through hole is provided on the side of the adjustment rod, through which the air conveying groove and the material conveying groove are switched and opened. A rubber membrane is attached to the side of the adjustment rod.

[0013] As a further embodiment of the present invention, an end plate is fixed to one end of the adjusting rod, a return spring is sleeved on the side of the adjusting rod, the two ends of the return spring are respectively fixed to the side of the end plate and the outer wall of the shaft, an annular plate is fixed to the inner wall of the processing cylinder, and a pressing block for pushing the adjusting rod is fixed to the side of the annular plate.

[0014] As a further embodiment of the present invention, both ends of the top pressing block are provided with inclined surfaces, and the end of the adjusting rod that engages with the top pressing block is provided with an arc-shaped end.

[0015] As a further embodiment of the present invention, a guide groove is provided on the side of the adjusting rod, and a protrusion that is slidably adapted to the guide groove is fixed in the groove on the shaft that is slidably engaged with the adjusting rod.

[0016] A feeding method using a lubricating oil processing feeding device includes the following steps: S1. The lubricating oil to be mixed is conveyed and added into the processing cylinder, and the rotating shaft drives multiple stirring rods to stir the material inside the processing cylinder. S2. The additive liquid is transported to the end cavity a through the feed pipe and then to the inner cavity a of the feed rod through the feed trough. The additive liquid in the inner cavity a flows out through multiple discharge holes and is fed to the filter plate for filtration. The feed rod is driven to rotate above the filter plate by the rotating shaft, so that the additive liquid is evenly fed to the filter plate for filtration by the rotating feed rod. S3. The solid impurities accumulated on the top surface of the filter plate can be uniformly sucked upwards and removed through multiple suction holes on the suction plate. The solid impurities are sequentially sucked out through the connecting pipe, air supply groove, end cavity b and suction pipe. The rotating shaft drives the suction plate to rotate above the filter plate, so that the suction holes can cover the entire area of ​​the filter plate, ensuring that the solid impurities are fully removed. S4. The rotating shaft drives the adjusting rod to rotate synchronously, causing the end of the adjusting rod to intermittently contact the top pressure block. When the end of the adjusting rod contacts the side of the top pressure block, the top pressure block pushes the adjusting rod to move and adjust. The return spring is in a stretched state. At this time, the through hole and the air delivery channel coincide, and the air delivery channel is opened. Solid impurities on the filter plate are sucked out through the suction hole. The material delivery channel is closed, and the delivery of additive liquid is paused. When the end of the adjusting rod disengages from the top pressure block, the adjusting rod automatically moves back to its original position under the elastic force of the return spring. At this time, the through hole and the material delivery channel coincide, and the material delivery channel is opened, so that the additive liquid can continue to be added to the filter plate. The suction hole is closed to suck out impurities, so that the additive filtration and impurity removal are continuously switched alternately.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. The feed assembly delivers the additive liquid evenly to the filter plate in a rotating manner for filtration, avoiding localized concentrated filtration on the filter plate. This ensures a uniform filtration load across all positions on the filter plate, allowing the additive liquid to continuously and evenly cover the entire filter surface. This reduces clogging or penetration caused by localized overload, lowers maintenance frequency and costs, and extends the service life of the filter plate. At the same time, the uniform filtration load ensures the continuity and consistency of the filtration process, improving the purity and quality of the filtered additive, and enhancing the quality of the finished product after mixing the additive and lubricating oil. 2. The impurity removal component is set up to uniformly remove the solid impurities that have accumulated on the top surface of the filter plate by upward suction. The impurity removal component can cover the entire area of ​​the filter plate, avoiding blind spots and ensuring that solid impurities are fully removed, thus improving the impurity removal effect. At the same time, the upward suction method effectively prevents impurities from falling back into the lubricating oil in the processing cylinder due to gravity or airflow disturbance during the cleaning process, thus avoiding secondary pollution. 3. By combining the feeding component and the impurity removal component, the addition of additives and the removal of impurities are carried out in a closed environment, which effectively isolates the intrusion of external dust, water vapor and other pollutants, ensuring the purity of the mixing process of lubricating oil and additives. At the same time, it avoids the volatilization of raw materials, the scattering of impurities and the splashing of lubricating oil, improves the safety of the working environment and reduces raw material loss. 4. By using a switching component, the feeding component and the impurity removal component can be intermittently switched, allowing for continuous cyclical switching between additive filtration and impurity removal. This ensures that the additive is added in small, multiple batches, avoiding the possibility of excessively high local concentrations caused by adding large amounts at once. This significantly shortens the time required for the additive and lubricating oil to mix evenly, improving mixing efficiency. Regarding impurity removal, the switching component automatically pauses the impurity removal component's suction of impurities when the additive is fed onto the filter plate, allowing sufficient filtration time for the filter plate. This prevents the impurity removal component from accidentally aspirating liquid additives. Furthermore, the impurity removal component removes solid impurities filtered from the filter plate in small, multiple batches, preventing excessive accumulation of impurities that could clog the mesh or penetrate the filter layer into the mixture. This results in a smoother workload for the impurity removal component, reducing wear and energy consumption. While improving the uniform mixing of lubricating oil and additives, it also provides more efficient, energy-saving, and reliable purification of the additives. Attached Figure Description

[0020] The present invention will be further described below with reference to embodiments.

[0021] Please see Figure 1-12This invention provides a feeding device for lubricating oil processing, including a processing cylinder 5. An inlet pipe 14 and a discharge pipe 15, communicating with the inside of the processing cylinder 5, are fixed to the outer wall of the processing cylinder 5. Valves 16 are installed on both the inlet pipe 14 and the discharge pipe 15. An electric heating plate 17 is installed at the bottom of the processing cylinder 5, which can heat the material inside the processing cylinder 5. A top plate 4 is fixed to the top of the processing cylinder 5. A filter plate 13 located at the upper part of the processing cylinder 5 is fixed to the inner wall of the processing cylinder 5. A shaft 6, rotatably penetrating the bottom side wall of the processing cylinder 5, the filter plate 13, and the top plate 4, is provided at the center inside the processing cylinder 5. A tooth is fixed to the bottom end of the shaft 6. A drive motor 8 is installed at the bottom of the processing cylinder 5, and a gear b10 that meshes with gear a9 is fixed to the output end of the drive motor 8. Multiple ring-shaped stirring rods 11 are fixed to the side of the shaft 6. A feeding assembly 1 is connected to the shaft 6 to uniformly add the additive liquid to the filter plate 13 for filtration. A cleaning assembly 2 is also connected to the shaft 6 to promptly remove impurities filtered out by the filter plate 13. A switching assembly 3 is installed between the feeding assembly 1 and the cleaning assembly 2. In operation, the valve 16 on the inlet pipe 14 is opened, allowing the lubricating oil to be mixed to be added into the processing cylinder 5 through the inlet pipe 14. The process is then started. The drive motor 8 operates, driving gear b10 to rotate via its output. Gear b10, in turn, rotates shaft 6 via gear a9. Multiple stirring rods 11 on the side of shaft 6 stir the lubricating oil inside the processing cylinder 5. During this process, the additive liquid is fed onto filter plate 13 via the feeding assembly 1, where it is filtered to remove impurities and improve purity. The filtered additive is then added relatively evenly to the lubricating oil inside the processing cylinder 5 for mixing. The rotating shaft 6 drives the feeding assembly... 1. The feed assembly rotates above the filter plate 13, thereby uniformly feeding the additive liquid onto the filter plate 13 in a rotating manner for filtration. This avoids localized concentrated filtration on the filter plate 13, ensuring a uniform filtration load across all positions on the filter plate 13. This allows the additive liquid to continuously and evenly cover the entire filtration surface of the filter plate 13, reducing clogging or penetration caused by localized overload, lowering maintenance frequency and costs, and extending the service life of the filter plate 13. At the same time, the uniform filtration load ensures the continuity and consistency of the filtration process, improving the purity and quality of the filtered additive, and enhancing the quality of the finished product after mixing the additive and lubricating oil. The rotating shaft 6 drives the impurity removal component 2 to rotate above the filter plate 13. This component 2 then uniformly suctions upwards to remove solid impurities accumulated on the top surface of the filter plate 13. This design allows the impurity removal component 2 to cover the entire area of ​​the filter plate 13, avoiding blind spots and ensuring thorough removal of solid impurities. This improves the impurity removal effect and significantly enhances the cleanliness of the filter surface and subsequent filtration efficiency. The upward suction method effectively prevents impurities from falling back into the lubricating oil in the processing cylinder 5 due to gravity or airflow disturbance during the cleaning process, avoiding secondary contamination and ensuring the purity of the lubricating oil and additive mixture. This not only ensures thorough cleaning but also reduces manual intervention and downtime. The combination of the feeding component 1 and the impurity removal component 2 allows additive addition and impurity removal to be carried out in a closed environment, effectively isolating external dust, moisture, and other contaminants. This ensures the purity of the lubricating oil and additive mixing process, while preventing raw material evaporation, impurity scattering, and lubricating oil splashing, improving the safety of the working environment and reducing raw material loss. The adjustable component 3 allows the feeding component to... The feeding component 1 and the impurity removal component 2 operate intermittently and alternately, continuously switching between additive filtration and impurity removal. This allows the additive to be added in small, multiple batches, avoiding the possibility of excessively high local concentrations caused by adding large amounts at once. This significantly shortens the time required for the additive and lubricating oil to mix evenly, improving mixing efficiency. Simultaneously, regarding impurity removal, the switching component 3 automatically pauses the impurity removal component 2's impurity suction when the additive is fed onto the filter plate 13 by the feeding component 1. This allows the filter plate 13 sufficient time to filter the additive, preventing the impurity removal component 2 from accidentally aspirating liquid additives. Furthermore, the impurity removal component 2 removes solid impurities filtered by the filter plate 13 in small, multiple batches, preventing excessive accumulation of impurities on the filter plate 13 that could clog the mesh or penetrate the filter layer into the mixture. This helps maintain stable filtration flux and long-term filtration accuracy, resulting in a smoother workload for the impurity removal component 2, reducing wear and energy consumption. While improving the uniform mixing of lubricating oil and additives, this method also provides more efficient, energy-saving, and reliable purification of the additives, demonstrating good engineering practicality and economic benefits.

[0022] Further as Figure 2 , Figure 3 , Figure 4 and Figure 7As shown, it is worth noting that the feeding assembly 1 includes a feeding rod 101 fixed to the side of the shaft 6. The feeding rod 101 is positioned above the filter plate 13. An inner cavity a102 is formed inside the feeding rod 101. A discharge hole 103 communicating with the inner cavity a102 is formed on the bottom side of the feeding rod 101. Multiple discharge holes 103 are provided and are equidistantly distributed. A conveying trough 104 arranged along the height of the shaft 6 and communicating with the inner cavity a102 is formed inside the shaft 6. An end cavity a105 communicating with the conveying trough 104 is formed at the top of the shaft 6. A feeding pipe 106 is rotatably connected to the top of the shaft 6 via a bearing. The feeding pipe 106 is connected to the end cavity a105. The additive liquid is conveyed to the end cavity a105 through the feeding pipe 106 and then further conveyed to the feeding rod 101 through the conveying trough 104. Inside the inner cavity a102, the additive liquid inside the inner cavity a102 flows out through multiple discharge holes 103 and is fed onto the filter plate 13 for filtration. During this process, the rotating shaft 6 drives the feeding rod 101 to rotate above the filter plate 13, thereby uniformly feeding the additive liquid onto the filter plate 13 for filtration. This avoids localized concentrated filtration on the filter plate 13, ensuring a uniform filtration load at all positions on the filter plate 13. This allows the additive liquid to continuously and evenly cover the entire filtration surface of the filter plate 13, reducing clogging or penetration caused by localized overload, lowering maintenance frequency and costs, and extending the service life of the filter plate 13. At the same time, the uniform filtration load ensures the continuity and consistency of the filtration process, improves the purity and quality of the filtered additive, and improves the quality of the finished product after mixing the additive and lubricating oil.

[0023] Further as Figure 3 , Figure 6 , Figure 7 and Figure 9As shown, it is worth noting that the impurity removal component 2 includes a connecting pipe 201 fixed to the side of the shaft 6. A suction plate 202 is fixed to the bottom end of the connecting pipe 201. The suction plate 202 has an inner cavity b203 communicating with the connecting pipe 201. A suction hole 204 communicating with the inner cavity b203 is provided on the bottom side of the suction plate 202. Multiple suction holes 204 are provided and are equidistantly distributed. The shaft 6... An air delivery groove 205 is provided inside the shaft 6, arranged along the height direction and connected to the connecting pipe 201. An end cavity b206, connected to the air delivery groove 205, is provided at the bottom end of the shaft 6. A suction pipe 207 is rotatably connected to the bottom end of the shaft 6 via a bearing, and the suction pipe 207 is connected to the end cavity b206. A suction pump is externally connected to the suction pipe 207, and the end cavity b206, air delivery groove 205, connecting pipe 201, and internal air delivery groove 205 are connected through the suction pipe 207. The cavity b203 has a negative pressure, which allows the solid impurities accumulated on the top surface of the filter plate 13 to be uniformly drawn upwards and removed through the multiple suction holes 204. The solid impurities are then sequentially drawn out through the connecting pipe 201, the air supply groove 205, the end cavity b206, and the suction pipe 207. The rotating shaft 6 drives the suction plate 202 to rotate above the filter plate 13, so that the suction plate 202 can cover the entire area of ​​the filter plate 13, avoiding blind spots and ensuring that solid impurities are fully removed, improving the impurity removal effect, significantly improving the cleanliness of the filter surface of the filter plate 13 and the subsequent filtration efficiency. At the same time, the upward suction method effectively prevents impurities from falling back into the lubricating oil in the treatment cylinder 5 due to gravity or airflow disturbance during the cleaning process, avoiding secondary pollution and ensuring the purity of the lubricating oil and additive mixture. This not only cleans thoroughly but also reduces manual intervention and downtime.

[0024] Further as Figure 3 , Figure 5 , Figure 6 and Figure 8As shown, it is worth noting that the switching assembly 3 includes a sliding adjustment rod 301 that slides through the air conveying channel 205 and the material conveying channel 104. A through hole 303 is provided on the side of the adjustment rod 301, through which the air conveying channel 205 and the material conveying channel 104 are switched open. A rubber membrane is attached to the side of the adjustment rod 301 to improve the sealing performance of the 301 in closing the material conveying channel 104 and the air conveying channel 205. In actual operation, the adjustment rod 301 is moved and adjusted. When the through hole 303 on the adjustment rod 301 coincides with the material conveying channel 104 or the air conveying channel 205, the material conveying channel 104 and the air conveying channel 205 are in the open state. Thus, the intermittently moving adjustment rod 301 switches the material conveying channel 104 and the air conveying channel 205 open. 05. The system intermittently opens and closes, allowing the discharge port 103 to intermittently add additives to the filter plate 13, while the suction port 204 intermittently removes solid impurities from the filter plate 13. This continuous cycle of additive filtration and impurity removal ensures that the additive is added in small amounts multiple times, avoiding excessively high local concentrations that may result from a single large addition. This significantly shortens the time required for the additive and lubricating oil to mix evenly, improving mixing efficiency. Simultaneously, regarding impurity removal, the system automatically pauses suction of the suction port 204 when the additive is added to the filter plate 13 through the discharge port 103, allowing the filter plate 13 sufficient filtration time to prevent the suction port 204 from accidentally aspirating additive liquid.

[0025] Further as Figure 8 , Figure 9 and Figure 10As shown, it is worth noting that an end plate 302 is fixed to one end of the adjusting rod 301, and a return spring 304 is sleeved on the side of the adjusting rod 301. The two ends of the return spring 304 are fixed to the side of the end plate 302 and the outer wall of the shaft 6, respectively. An annular plate 307 is fixed to the inner wall of the processing cylinder 5, and a pressing block 308 for pushing the adjusting rod 301 is fixed to the side of the annular plate 307. Multiple pressing blocks 308 are arranged in a ring. In actual operation, the rotating shaft 6 drives the adjusting rod 301 to rotate synchronously, so that the end of the adjusting rod 301 intermittently abuts against the pressing block 308. When the end of the adjusting rod 301 contacts the side of the pressing block 308, the pressing block 308 pushes the adjusting rod 301. 8. Push the adjustment rod 301 to move and adjust. The reset spring 304 is in the stretched state. At this time, the through hole 303 and the air delivery channel 205 are aligned. The air delivery channel 205 is opened. The solid impurities on the filter plate 13 are sucked out and removed through the suction hole 204. The material delivery channel 104 is closed, and the delivery of additive liquid is suspended. When the end of the adjustment rod 301 is disengaged from the top pressure block 308, the adjustment rod 301 is automatically moved and reset under the elastic force of the reset spring 304. At this time, the through hole 303 and the material delivery channel 104 are aligned. The material delivery channel 104 is opened, so that the additive liquid can continue to be added to the filter plate 13. The suction hole 204 is closed to suck out impurities, so that the additive filtration and impurity removal are continuously cycled and alternated.

[0026] Further as Figure 5 and Figure 6 As shown, it is worth noting that both ends of the top pressure block 308 are provided with inclined surfaces 309, and the end of the adjusting rod 301 that engages with the top pressure block 308 is provided with an arc-shaped end 306. The inclined surfaces 309 and the arc-shaped end 306 work together to guide the end of the adjusting rod 301 to slide against the side of the top pressure block 308, thereby improving working stability.

[0027] This solution includes the following working process: Valve 16 on the inlet pipe 14 is opened, allowing lubricating oil to be supplied to the interior of the processing cylinder 5 via the inlet pipe 14. The output of the drive motor 8 drives gear b10 to rotate, which in turn drives shaft 6 to rotate via gear b10 and gear a9. Multiple stirring rods 11 on the side of shaft 6 stir the lubricating oil inside the processing cylinder 5. During this process, additive liquid is supplied to end cavity a105 via feed pipe 106 and then further supplied to inner cavity a102 of discharge rod 101 via feed trough 104. The additive liquid in inner cavity a102 flows out through multiple discharge holes 103 and is fed to filter plate 13 for filtration. After filtration by filter plate 13... The additive is added to the lubricating oil in the processing cylinder 5 and stirred. The rotating shaft 6 drives the feeding rod 101 to rotate above the filter plate 13, thereby evenly feeding the additive liquid onto the filter plate 13 for filtration. The suction pipe 207 creates negative pressure in the end cavity b206, the air supply groove 205, the connecting pipe 201, and the inner cavity b203, so that the solid impurities accumulated on the top surface of the filter plate 13 can be evenly sucked upward and removed through multiple suction holes 204. The solid impurities are sequentially sucked out through the connecting pipe 201, the air supply groove 205, the end cavity b206, and the suction pipe 207. The rotating shaft 6 drives the suction plate 202 above the filter plate 13. The rotation allows the suction hole 204 to cover the entire area of ​​the filter plate 13, ensuring thorough removal of solid impurities. The rotating shaft 6 drives the adjusting rod 301 to rotate synchronously, causing the end of the adjusting rod 301 to intermittently contact different pressure blocks 308. When the end of the adjusting rod 301 contacts the side of the pressure block 308, the pressure block 308 pushes the adjusting rod 301 to move and adjust. The return spring 304 is in a stretched state. At this time, the through hole 303 and the air delivery groove 205 coincide, and the air delivery groove 205 is opened. Solid impurities on the filter plate 13 can be suctioned and removed through the suction hole 204. The material delivery groove 104 is closed, pausing the delivery of the additive liquid. When the end of the adjusting rod 301 disengages from the pressure block 308... At this time, under the elastic pull of the reset spring 304, the adjustment rod 301 automatically moves and resets. At this time, the through hole 303 and the feed trough 104 coincide, and the feed trough 104 is opened, so that the additive liquid can continue to be added to the filter plate 13. The suction hole 204 is closed to suck up impurities, so that the additive filtration and impurity removal are continuously switched, so that the additive is added and filtered in small amounts multiple times, avoiding the possibility of excessively high local concentration caused by adding a large amount at once. At the same time, in terms of impurity removal, when the additive is fed to the filter plate 13 through the discharge hole 103, the suction hole 204 is automatically paused to suck up impurities, so as to reserve a certain filtration time for the filter plate 13 to filter the additive and prevent the suction hole 204 from accidentally sucking up the additive liquid.

[0028] Further as Figure 9 and Figure 10 As shown, it is worth noting that a guide groove 305 is provided on the side of the adjusting rod 301, and a protrusion that slides and adapts to the guide groove 305 is fixed in the groove on the shaft 6 that is in sliding cooperation with the adjusting rod 301. In actual operation, the adjusting rod 301 is guided and limited by the cooperation of the protrusion and the guide groove 305 to avoid the deflection of the adjusting rod 301, and to ensure that the through hole 303 can accurately coincide with the material conveying trough 104 or the air conveying trough 205, so as to open and close the material conveying trough 104 or the air conveying trough 205.

[0029] Further as Figure 9 As shown, it is worth noting that multiple round holes 12 are provided on the side of the stirring rod 11. The diameter of the round holes 12 gradually increases from top to bottom along the height direction of the processing cylinder 5. When the stirring rod 11 is stirring, some fluid can flow out through the round holes 12 on the stirring rod 11. The round holes 12 improve the agitation of the stirring rod 11 on the mixing of lubricating oil and additives inside the processing cylinder 5, thereby improving the overall stirring effect. After stirring is completed, the material is discharged through the discharge pipe 15 by opening the valve 16 on the discharge pipe 15.

[0030] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the bottom of the processing cylinder 5 is fixed with a base plate 7, and the drive motor 8 is fixedly installed on the top of the base plate 7.

[0031] A feeding method using a lubricating oil processing feeding device includes the following steps: S1. The lubricating oil to be mixed is conveyed and added into the processing cylinder 5. The rotating shaft 6 drives multiple stirring rods 11 to stir the material inside the processing cylinder 5. S2. The additive liquid is conveyed into the end cavity a105 through the feed pipe 106, and then further conveyed into the inner cavity a102 of the feed rod 101 through the feed trough 104. The additive liquid in the inner cavity a102 flows out through multiple discharge holes 103 and is fed onto the filter plate 13 for filtration. The rotating shaft 6 drives the feed rod 101 to rotate above the filter plate 13, thereby evenly feeding the additive liquid onto the filter plate 13 for filtration through the rotating feed rod 101. S3. The solid impurities accumulated on the top surface of the filter plate 13 can be uniformly sucked upwards and removed through the multiple suction holes 204 on the suction plate 202. The solid impurities are sequentially sucked out through the connecting pipe 201, the air supply groove 205, the end cavity b206 and the suction pipe 207. The rotating shaft 6 drives the suction plate 202 to rotate above the filter plate 13, so that the suction holes 204 can cover the entire area of ​​the filter plate 13, ensuring that the solid impurities are fully removed. S4. The rotating shaft 6 drives the adjusting rod 301 to rotate synchronously, so that the end of the adjusting rod 301 intermittently abuts against the top pressure block 308. When the end of the adjusting rod 301 contacts the side of the top pressure block 308, the top pressure block 308 pushes the adjusting rod 301 to move and adjust. The return spring 304 is in a stretched state. At this time, the through hole 303 and the air delivery groove 205 coincide, the air delivery groove 205 is opened, and the solid impurities on the filter plate 13 are extracted through the suction hole 204. When the additive liquid is removed, the feed trough 104 is closed, and the delivery of the additive liquid is suspended. When the end of the adjusting rod 301 is disengaged from the top pressure block 308, the adjusting rod 301 automatically moves and resets under the elastic pull of the return spring 304. At this time, the through hole 303 and the feed trough 104 coincide, and the feed trough 104 is opened, so that the additive liquid can continue to be added to the filter plate 13. The suction hole 204 is closed to suck up impurities, so that the additive filtration and impurity removal are continuously switched alternately.

[0032] In summary: The rotating shaft 6 drives the feeding assembly 1 to rotate above the filter plate 13, thereby uniformly feeding the additive liquid onto the filter plate 13 in a rotating manner for filtration. This avoids localized concentrated filtration on the filter plate 13, ensuring a uniform filtration load across all positions on the filter plate 13. This allows the additive liquid to continuously and evenly cover the entire filtration surface of the filter plate 13, reducing clogging or penetration caused by localized overload, lowering maintenance frequency and costs, and extending the service life of the filter plate 13. Simultaneously, the uniform filtration load ensures the continuity and consistency of the filtration process, improving the purity and quality of the filtered additive, and ultimately enhancing the quality of the finished product after mixing the additive and lubricating oil. The rotating shaft 6 drives... The impurity removal component 2 rotates above the filter plate 13, thereby uniformly sucking upwards to remove solid impurities accumulated on the top surface of the filter plate 13. This design allows the impurity removal component 2 to cover the entire area of ​​the filter plate 13, avoiding blind spots and ensuring that solid impurities are fully removed, improving the impurity removal effect and significantly enhancing the cleanliness of the filter surface of the filter plate 13 and the subsequent filtration efficiency. Simultaneously, the upward suction method effectively prevents impurities from falling back into the lubricating oil in the processing cylinder 5 due to gravity or airflow disturbance during the cleaning process, avoiding secondary contamination and ensuring the purity of the lubricating oil and additive mixture. This not only ensures thorough cleaning but also reduces manual intervention and downtime. This is achieved through the cooperation of the feeding component 1 and the impurity removal component 2. The additive addition and impurity removal are carried out in a closed environment, effectively isolating the intrusion of external dust, moisture, and other pollutants, ensuring the purity of the lubricating oil and additive mixing process. This also prevents raw material volatilization, impurity scattering, and lubricating oil splashing, improving the safety of the working environment and reducing raw material loss. The switching component 3 allows the feeding component 1 and the impurity removal component 2 to intermittently alternate, continuously cycling and alternating the additive filtration and impurity removal processes. This ensures that the additive is added in small, multiple batches, avoiding the possibility of excessively high local concentrations caused by large single additions. This significantly shortens the time required for the additive and lubricating oil to mix evenly, improving mixing efficiency. Regarding impurity removal, the switching component 3 automatically pauses the impurity removal component 2 when the feed component 1 delivers the additive to the filter plate 13 for filtration. This allows the filter plate 13 sufficient time to filter the additive, preventing the impurity removal component 2 from accidentally aspirating the additive liquid. Furthermore, the impurity removal component 2 removes solid impurities filtered by the filter plate 13 in small, multiple steps, preventing excessive accumulation of impurities in certain areas of the filter plate 13 that could clog the mesh or penetrate the filter layer and fall into the mixture. This helps maintain stable filtration flux and long-term filtration accuracy, resulting in a smoother workload for the impurity removal component 2, reducing wear and energy consumption. While improving the uniform mixing of lubricating oil and additives, it also provides more efficient, energy-saving, and reliable purification of the additives.
