Description

Technical Field

[0001] This utility model relates to the field of lubricating oil processing, and in particular to a high-precision filtration and purification device for lubricating oil processing. Background Technology

[0002] During the processing and use of lubricating oil, impurities and contaminants gradually accumulate over time. These impurities not only affect the performance of the lubricating oil but can also damage mechanical equipment, leading to equipment failure, increased wear, and even equipment downtime. Therefore, effectively removing large particulate impurities and tiny bacteria, dust, and other contaminants from lubricating oil has become an urgent problem to be solved in the processing and use of lubricating oil.

[0003] Some existing filtration and purification equipment can only remove larger impurities, while the filtration effect on small impurities is not good. After a period of filtration, the machine needs to be stopped to clean the filter screen. Otherwise, the filtration and purification effect will be greatly reduced, the service life of the equipment will be shortened, and it cannot be used continuously. This increases downtime and labor costs, and the maintenance and cleaning of the equipment is also relatively cumbersome.

[0004] Therefore, it is necessary to further improve the high-precision filtration and purification equipment used in lubricating oil processing. Utility Model Content

[0026] Please see Figures 1-5 This utility model provides a technical solution: a high-precision filtration and purification device for lubricating oil processing. This device is mainly used to efficiently remove impurities from lubricating oil, including larger solid impurities and tiny particles, to ensure the efficient use of lubricating oil and extend the service life of the equipment.

[0027] Purification tank 1 is the core component of this equipment, responsible for containing the lubricating oil to be filtered. The top of purification tank 1 has an outlet, which connects to an external pipeline via an outlet pipe 4, allowing the filtered lubricating oil to be discharged. The inlet of purification tank 1 is located on its side, allowing the lubricating oil to be purified to enter. A filter assembly 3 is installed on the inlet to initially remove larger impurities from the lubricating oil. This filter assembly 3 includes an inlet pipe 301 and a filter tank 302. The distal end of the inlet pipe 301 is connected to the inlet of purification tank 1, and the inlet pipe 301 is tangentially angled to the cross-section of purification tank 1, ensuring that the lubricating oil generates a swirling flow after entering purification tank 1, which helps to evenly distribute the oil and prevent clogging.

[0028] A removal pipe 12 is installed at the center of the bottom of the purification tank 1. A rotating seal is provided between the removal pipe 12 and the purification tank 1 to increase the sealing performance. The removal pipe 12 is used to collect and remove impurities generated during the filtration process. The lower end of the removal pipe 12 is connected to the circulation assembly 2 via a rotary joint 5. A drive assembly 6 is provided on the lower section of the side surface of the removal pipe 12, which can drive the removal pipe 12 to rotate. The drive assembly 6 includes a driven gear 601, a driving gear 602, and a drive motor 603. The driven gear 601 and the driving gear 602 mesh with each other. The driving gear 602 is keyed to the end of the output shaft of the drive motor 603. The driven gear 601 is installed on the lower section of the side surface of the removal pipe 12. The drive motor 603 is mounted on the lower surface of the purification tank 1 via a mounting bracket. The driven gear 601 and the driving gear 602 form a gear system. The drive assembly 6 provides power to the removal pipe 12 through the gear system and the drive motor 603 to ensure that the removal pipe 12 can rotate at an appropriate speed and enhance the impurity removal efficiency.

[0029] The circulation assembly 2 mainly includes a circulation pump 201 and a circulation pipe 202. One end of the circulation pipe 202 is installed at the inlet of the circulation pump 201, and the other end is connected to the impurity removal pipe 12 via a rotary joint 5. The circulation pump 201 provides a certain pressure to introduce the lubricating oil containing impurities into the impurity removal pipe 12, enhancing the purification effect of the equipment. Through pumping, the lubricating oil is guided into the impurity removal pipe 12, and impurities are further removed by the rotation of the impurity removal pipe 12. The outlet of the circulation pump 201 can be connected to an unfiltered lubricating oil container, facilitating the re-filtration of lubricating oil containing impurities.

[0030] The suction assembly 11 is arrayed along the outer wall of the impurity removal tube 12. The suction assembly 11 includes a conical shroud 1101 and a connecting tube 1102. The conical shroud 1101 is located at the end of the connecting tube 1102, corresponding to the conical filter screen 10. The suction assembly 11 uses negative pressure suction to adsorb impurities on the conical filter screen 10 into the impurity removal tube 12, thereby achieving efficient purification. The conical shroud 1101 effectively covers the filter surface of the conical filter screen 10, ensuring that impurities pass through the conical shroud 1101 and the connecting tube 1102 into the impurity removal tube 12.

[0031] A placement ring 7 and a clamping assembly 9 are provided on the inner wall of the purification tank 1 for fixing and supporting the conical filter screen 10. The clamping assembly 9 includes a clamping plate 901 and a positioning block 902. The clamping plate 901 is detachably connected to the purification tank 1 at both ends and abuts against the conical filter screen 10 to ensure the stability of the filter screen. The positioning block 902 is assembled on the lower surface of the clamping plate 901 and is set on the upper surface of the conical filter screen 10 to prevent the conical filter screen 10 from shifting under high-pressure working conditions. The conical filter screen 10 is used to filter out tiny impurities in lubricating oil, with high filtration accuracy and effective removal of fine particles.

[0032] A sealing gasket ring 8, made of nitrile rubber, is provided between the conical filter screen 10 and the placement ring 7, providing excellent sealing performance. Nitrile rubber has high oil resistance and abrasion resistance, enabling it to operate stably under high pressure and high temperature conditions, ensuring no lubricating oil leakage during the filtration process.

[0033] The working principle of this utility model is as follows:

[0034] Lubricating oil enters the purification tank 1 through the inlet pipe 301. The tangential angle between the inlet pipe 301 and the purification tank 1 is set so that the lubricating oil generates a swirling flow when it enters the purification tank 1, thus avoiding the problem of uneven lubricating oil flow.

[0035] Before entering the purification tank 1, the lubricating oil undergoes preliminary filtration through the filter assembly 3, removing larger impurities and preventing them from entering subsequent filtration processes. The filtered lubricating oil then flows into the purification tank 1 and undergoes secondary filtration through the conical filter screen 10. The design of the conical filter screen 10 ensures that minute impurities in the lubricating oil are effectively removed, resulting in high filtration accuracy.

[0036] The impurity removal pipe 12 rotates, driving the suction assembly 11 to rotate, further removing impurities adhering to the surface of the conical filter screen 10. The circulation assembly 2 provides a certain pressure to ensure a negative pressure exists between the impurity removal pipe 12 and the suction assembly 11. Through the negative pressure, the suction assembly 11 draws impurities blocked by the lubricating oil flowing through the conical filter screen 10 into the impurity removal pipe 12, thereby achieving efficient purification.

[0037] After purification, the lubricating oil is discharged through the outlet pipe 4, ready to re-enter the lubrication system.

[0038] The method of using this utility model is as follows:

[0039] During installation, ensure all components are securely connected, especially the connection between filter assembly 3 and purification tank 1, and the connection between drive assembly 6 and impurity removal pipe 12, ensuring no leaks. During commissioning, ensure the circulation pump 201 provides sufficient pressure and the drive motor 603 provides sufficient power to drive the impurity removal pipe 12 to rotate;

[0040] Before starting the equipment, check that all parts of the equipment are correctly installed and tightened. After the lubricating oil enters the purification tank 1, it is filtered by the conical filter screen 10, and the clean lubricating oil is discharged through the liquid outlet pipe 4.

[0041] Start the drive motor 603 to ensure that the impurity removal pipe 12 can rotate. Start the circulation pump 201 to generate negative pressure in the impurity removal pipe 12 and the suction assembly 11. The suction assembly 11 will suck away the impurities on the conical filter screen 10 to ensure the filtration effect of the conical filter screen 10.

[0042] The drive motor 603 and the circulation pump 201 can be turned on at regular intervals to clean the conical filter screen 10 at regular intervals. The manual valve on the circulation pipe 202 can be turned on at regular intervals along with the drive motor 603 and the circulation pump 201 to prevent all the lubricating oil from flowing out through the impurity removal pipe 12. The pipe diameter of the impurity removal pipe 12 should be smaller than the pipe diameter of the liquid outlet pipe 4 to ensure that the filtered lubricating oil can be discharged through the liquid outlet pipe 4.

[0043] It is worth noting that the inlet of the purification tank 1 should be lower than the bottom of the conical filter screen 10 to ensure that the lubricating oil is filtered through the conical filter screen 10. The upper part of the conical filter screen 10 contains the purified lubricating oil, and the upper part of the conical filter screen 10 contains the unpurified lubricating oil. The drive motor 603 and the circulation pump 201 are electrically connected to an external controller so that the external controller can control the start and stop of the drive motor 603 and the circulation pump 201. The drive motor 603 can be an ABB servo motor, and the circulation pump 201 can be a petrochemical rotating circulation pump 201 to prevent corrosion and leakage, and has high durability and stability.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
