Description

Technical Field

[0001] This utility model relates to the technical field of lubricating oil mixing auxiliary devices, and in particular to a lubricating oil mixing device with a stirring function. Background Technology

[0002] In the final stage of assembly, the lubricating oil should not have inconsistent quality due to material processes such as sedimentation. Therefore, it is necessary to maintain uniform mixing and overall fluidity of the oil during the filling process. The lubricating oil is stored in a storage container. During long-term use, dust in the air can easily enter, causing certain impurities to accumulate inside the storage container. If it is directly mixed, it will affect the final quality of the lubricating oil.

[0003] Existing mixing devices often only use a motor to drive the stirring rod to rotate. The mixed lubricating oil is not filtered and discharged, which may contain impurities and affect the actual performance of the lubricating oil. Utility Model Content

[0004] To address the technical problem of inconvenient filtration in existing lubricating oil blending processes, this invention provides a lubricating oil blending device with a stirring function.

[0005] The technical solution of this utility model is achieved through the following scheme: a lubricating oil mixing device with stirring function, including a mixing tank, a filtering and stirring system and a pressure filter assembly. The top opening of the mixing tank is detachably installed with a cap. The cap is provided with a filtering and stirring system, a lubricating oil inlet pipe and an additive inlet pipe. The filtering and stirring system penetrates through the cap. The mixing tank is also provided with a reflux device. The lubricating oil inlet pipe is provided with a pressure filter assembly and an oil inlet.

[0006] Through the above technical solutions, the pressure filter assembly performs preliminary filtration of the lubricating oil before it enters the mixing tank, removing larger particulate impurities. This is combined with a subsequent filtration and stirring system for multi-stage filtration, efficiently removing various impurities from the lubricating oil, ensuring the purity of the final lubricating oil, improving the mixing quality, and enhancing consistency through stirring. The reflux device allows the lubricating oil to circulate and be stirred during the mixing process, effectively breaking down localized concentration differences and ensuring a more uniform distribution and mixing of the components, further improving the uniformity and quality of the mixing.

[0007] Preferably, the filtration and stirring system includes a second filter screen, a scraper, rotating blades, and a first drive motor. The first drive motor is located on the upper surface of the cap, and the drive end of the first drive motor passes through the cap and is connected to the rotating shaft. The second filter screen and the third filter screen are installed sequentially on the rotating shaft. The scraper is fixedly installed between the second filter screen and the third filter screen, and a plurality of rotating blades are rotatably installed between the scraper and the rotating shaft.

[0008] Preferably, the rotating shaft passes through the third filter screen and is connected to the stirring fan.

[0009] Through the above technical solution, the second and third filters installed sequentially on the rotating shaft constitute a multi-stage filtration system. The second filter provides a pure raw material base for the subsequent stirring and mixing process, while the third filter performs final filtration of the oil during the stirring process to ensure the purity of the final lubricating oil. The scraper scrapes the inner surface of the mixing tank to prevent impurities from accumulating and promotes thorough mixing of the oil and additives. The stirring fan rotates continuously in the mixing area to effectively prevent the lubricating oil from settling and separating. The rotating blades rotate horizontally under the impact force generated by the rotating shaft, further increasing the stirring intensity and fully covering the stirring area to thoroughly stir the lubricating oil and additives, avoiding local concentration differences.

[0010] Preferably, the reflux device includes a reflux box, a second drive motor, and a spiral conveying roller. The second drive motor is mounted on the top surface of the reflux box, and the drive end of the second drive motor is connected to the spiral conveying roller. The spiral conveying roller is located inside the reflux box and is adapted to the reflux box.

[0011] Preferably, the reflux box is C-shaped and connected to the mixing tank, with the oil inlet of the reflux box located below the third filter screen and the oil outlet of the reflux box located above the third filter screen.

[0012] Through the above technical solutions, the circulation system formed by the reflux device ensures that the lubricating oil in the mixing tank is always in a dynamic equilibrium state. The second drive motor provides stable power to the screw conveyor roller, ensuring that the reflux device can operate continuously and stably, guaranteeing the continuity of the lubricating oil mixing process. The screw conveyor roller ensures smooth conveying of lubricating oil in the reflux box, reducing oil reflux blockage.

[0013] Preferably, the filter press assembly includes a linear actuator and a first filter screen, the linear actuator being mounted on the top of the lubricating oil inlet pipe and the first filter screen being detachably mounted on the side wall of the lubricating oil inlet pipe.

[0014] Preferably, the oil inlet is located between the linear drive and the first filter.

[0015] Preferably, the first filter screen includes a filter screen and a pull-out clip. The pull-out clip has an arc groove adapted to the filter screen. The end of the pull-out clip has a protrusion. A spring block is movably installed in the protrusion. The filter screen is detachably installed in the pull-out clip via the spring block.

[0016] The above technical solution uses a linear actuator to generate pressure, which pushes the lubricating oil through the first filter screen quickly, thereby improving the filtration speed of the lubricating oil.

[0017] In summary, this utility model has the following beneficial effects:

[0018] 1. This utility model uses a pressure filter assembly to perform preliminary filtration of lubricating oil before it enters the mixing tank, removing larger particulate impurities. Combined with a subsequent filtration and stirring system, it performs multi-stage filtration, efficiently removing various impurities from the lubricating oil, ensuring the purity of the final lubricating oil, improving the mixing quality, and enhancing consistency through stirring. This ensures the uniformity of the lubricating oil within the mixing tank. The reflux device allows the lubricating oil to circulate and be stirred during the mixing process, effectively breaking down localized concentration differences in the lubricating oil, resulting in a more uniform distribution and mixing of the components, further improving the uniformity and quality of the mixing.

[0019] 2. The second and third filters installed sequentially on the rotating shaft constitute a multi-stage filtration system. The second filter provides a pure raw material base for the subsequent stirring and mixing process, while the third filter performs final filtration of the oil during the stirring process to ensure the purity of the final lubricating oil. The scraper scrapes the inner surface of the mixing tank to prevent impurities from accumulating and promotes thorough mixing of the oil and additives. The stirring fan rotates continuously in the mixing area to effectively prevent the lubricating oil from settling and separating. The rotating blades rotate horizontally under the impact force generated by the rotating shaft, further increasing the stirring intensity and fully covering the stirring area to thoroughly stir the lubricating oil and additives, avoiding local concentration differences.

[0020] 3. The circulation system formed by the reflux device keeps the lubricating oil in the mixing tank in a dynamic balance. The second drive motor provides stable power to the screw conveyor roller, ensuring that the reflux device can operate continuously and stably, guaranteeing the continuity of the lubricating oil mixing process. The screw conveyor roller ensures smooth conveying of lubricating oil in the reflux box, reducing oil backflow blockage.

[0021] 4. Pressure is generated by a linear actuator to push the lubricating oil through the first filter screen quickly, thereby increasing the filtration speed of the lubricating oil. Attached Figure Description

[0031] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0032] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification. The present invention will be further described in detail below with reference to the accompanying drawings.

[0033] A lubricating oil mixing device with a stirring function, such as Figures 1-7As shown, the system includes a mixing tank 1, a filtration and stirring system 2, and a filter press assembly 4. A detachable cap is installed at the top opening of the mixing tank 1. The cap houses the filtration and stirring system 2, a lubricating oil inlet pipe 6, and an additive inlet pipe 8. The filtration and stirring system 2 penetrates the cap. A reflux device 3 is also provided on the mixing tank 1. The lubricating oil inlet pipe 6 is equipped with the filter press assembly 4 and an oil inlet 7. An oil outlet is located at the bottom of the mixing tank 1. Pumps are installed on both the oil outlet and the oil inlet 7. The lubricating oil mixing... The completed section has an observation window to allow staff to observe the lubricating oil mixing results. The top is fixed to the opening of the mixing tank 1 by multiple bolts. The drive end of the filtration and stirring system 2 is located on the top. The cleaning section of the filtration and stirring system 2 is located inside the mixing tank 1. The oil is quickly pressed into the mixing tank 1 through the filter press assembly 4 and undergoes preliminary filtration. The subsequent filtration and stirring of the lubricating oil and additives by the filtration and stirring system 2, together with the reflux device 3, allows the lubricating oil in the mixing process to be circulated, thereby improving the uniformity and quality of the mixing.

[0034] like Figure 2 and Figure 3 As shown, the filtration and stirring system 2 includes a second filter screen 21, a scraper 22, rotating blades 23, and a first drive motor 24. The first drive motor 24 is located on the upper surface of the cap, and its drive end passes through the cap and is connected to a rotating shaft. The second filter screen 21 and a third filter screen 25 are sequentially installed on the rotating shaft. The scraper 22 is fixedly installed between the second filter screen 21 and the third filter screen 25. Several rotating blades 23 are rotatably installed between the scraper 22 and the rotating shaft. The scraper 22 is generally door-shaped, with two angled ends that abut against the mixing tank 1. During the stirring process, it can effectively scrape the inner surface of the mixing tank 1 to prevent impurities from accumulating. The horizontal end of the scraper 22 is connected to the second filter screen 21. The second filter screen 21 is frustum-shaped, while the two vertical ends of the scraper 22 are connected to the third filter screen 25 and rotated by a rotating shaft. Eight rotating blades 23 support rollers are mounted horizontally between the scraper 22 and the rotating shaft. Each support roller has two rotating blades 23. When the rotating shaft rotates axially, the rotating blades 23 are impacted and rotate horizontally, increasing the stirring. The lubricating oil and additives are stirred and mixed between the second filter screen 21 and the third filter screen 25. The second filter screen 21 filters the lubricating oil and additives when they enter the mixing tank 1, which can efficiently intercept larger particulate impurities, providing a purer raw material base for the subsequent stirring and mixing process, reducing the wear of impurities on the stirring components, and extending the service life of the equipment.

[0035] The third filter 25 performs final filtration of the oil, further removing minute impurities or insufficiently mixed particles that may be generated during the stirring process, ensuring that the final lubricating oil has extremely high purity and meets the requirements for high-quality lubricating oil. Multi-stage filtration improves the purity of the lubricating oil. The rotating shaft passes through the third filter 25 and is connected to the stirring fan 5. The stirring fan 5 is located at the position where the lubricating oil is prepared. The rotation of the stirring fan 5 ensures that the prepared lubricating oil will not settle or separate. When the rotating shaft rotates, the second filter 21 and the third filter 25 also rotate with the rotating shaft, accelerating the oil filtration.

[0036] like Figure 1 and Figure 2 As shown, the reflux device 3 includes a reflux box 31, a second drive motor 32, and a spiral conveying roller 33. The second drive motor 32 is installed on the top surface of the reflux box 31, and its drive end is connected to the spiral conveying roller 33. The spiral conveying roller 33 is located inside the reflux box 31 and is adapted to fit the reflux box 31. The inner cavity of the reflux box 31 is blocked by the spiral conveying roller 33 to prevent the upper layer of oil from flowing into the blended oil without passing through the third filter screen 25. The reflux box 31 is C-shaped and connected to the blending tank 1. The oil inlet of the reflux box 31 is located below the third filter screen 25, and the oil outlet of the reflux box 31 is located above the third filter screen 25. The reflux box 31 draws oil from the blending tank below the third filter screen 25. The lubricating oil is fed into the storage space and discharged from above the third filter screen 25 for repeated filtration. During the reflux process, the lubricating oil flows upward continuously under the push of the screw conveyor roller 33, effectively breaking down any potential local concentration differences and making the components in the lubricating oil more evenly distributed, further improving the uniformity and quality of the blend. The third filter screen 25 further removes any tiny impurities or insufficiently mixed particles that may be generated during the stirring process. The circulation effect of the reflux device 3 keeps the lubricating oil flowing, avoiding excessive accumulation of impurities in local areas. At the same time, through multiple filtrations, the impurity content in the lubricating oil is reduced, improving the quality and stability of the lubricating oil.

[0037] like Figure 4 and Figure 5As shown, the filter press assembly 4 includes a linear actuator 41 and a first filter screen 42. The linear actuator 41 is installed at the top of the lubricating oil inlet pipe 6, and the first filter screen 42 is detachably installed on the side wall of the lubricating oil inlet pipe 6. The oil inlet 7 is located between the linear actuator 41 and the first filter screen 42. The linear actuator 41 is preferably a servo electric cylinder, which can accurately control the pressure and propulsion speed of the oil during the filter press process, flexibly adjust the filter press parameters, ensure stable and efficient filter press effect, and accurately control to avoid problems such as incomplete filtration or filter screen damage caused by excessive or insufficient pressure. The first filter screen 42 can be pulled out and installed on the side wall of the lubricating oil inlet pipe 6. When the filter screen becomes clogged or damaged due to long-term use, it is only necessary to simply pull the first filter screen 42 out from the side wall of the inlet pipe for cleaning or replacement with a new filter screen, which shortens the equipment downtime for maintenance. Before entering the mixing tank 1, the oil first passes through the first filter screen 42 for preliminary filtration to remove larger particulate impurities. The preliminary filtration of the first filter screen 42 can effectively reduce the burden of subsequent processing links and improve the overall filtration efficiency.

[0038] like Figure 6 and Figure 7 As shown, the first filter screen 42 and the lubricating oil inlet pipe 6 are equipped with spring pull buckles 10. The first filter screen 42 includes a filter screen and a pull-out clip. The pull-out clip has an arc groove adapted to the filter screen. The end of the pull-out clip has a protrusion, and a spring block 9 is movably installed in the protrusion. The filter screen is detachably installed in the pull-out clip through the spring block 9 to prevent lubricating oil leakage. The side wall of the lubricating oil inlet pipe 6, which is engaged with the pull-out clip, has a groove adapted to the protrusion. The protrusion of the pull-out clip is inserted into the groove and fixed to the lubricating oil inlet pipe 6 by the spring pull buckle 10. Both sides of the spring block 9 have slopes. When the filter screen is inserted into the pull-out clip, the filter screen squeezes the spring block 9. When compressed, spring block 9 retracts smoothly into the protrusion along the slope, eliminating the need for manual adjustment and automatically creating space for filter insertion. The filter insertion part is designed as a protrusion that matches the arc groove on the pull-out connector. During insertion, the protrusion and arc groove work together to provide precise guidance, ensuring the filter is accurately inserted into the designated position within the pull-out connector. The spring block 9 rebounds and abuts against the protrusion of the filter insertion part, securing it and preventing issues such as insecure installation or poor sealing due to insertion position deviation. To remove the filter, simply press the spring block.

[0039] Working principle: The operator starts the pump at the oil inlet 7 to deliver oil and feeds the additives through the additive feed pipe 8. The filter press 4 further accelerates the oil feeding and preliminary filtration. The operator then starts the first drive motor 24. When the oil and additives enter the mixing tank 1, they are first filtered by the second filter screen 21 to efficiently filter the lubricating oil and additives entering the mixing zone. In the mixing zone, the rotating shaft drives the scraper 22 and the rotating plate to rotate. At the same time, the rotating plate 23 rotates horizontally under the impact force generated by the axial rotation on the rotating shaft, increasing the mixing force. The mixed oil continues to pass through the third filter screen 25 for final filtration. The mixing process is gradually completed in the mixing tank 1.

[0040] Staff members observe the lubricating oil mixing results in real time through the observation window. At this time, the reflux device 3 is activated to extract the mixed oil from the storage space below the third filter screen 25, and then discharge it from the top of the third filter screen 25, re-entering the mixing area in the mixing tank 1 for repeated filtration and mixing.

[0041] After the mixing process is completed, the staff will turn off the relevant pumps and motors, open the pump at the oil outlet at the bottom of the mixing tank 1, and discharge the mixed high-quality lubricating oil from the oil outlet for subsequent storage or use.

[0042] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
