Technical Field

[0001] This utility model relates to the field of lubricating oil filtration and decolorization technology, and in particular to a lubricating oil filtration and decolorization device. Background Technology

[0002] Lubricating oil is an oily liquid used to reduce friction and wear in mechanical parts. It consists of base oil and additives and is widely used in automobiles, industrial equipment, and other fields. It requires filtration and decolorization primarily because impurities such as metal shavings and dust can become trapped during use, and oxidation can cause it to darken in color and deteriorate in performance. Filtration removes impurities and maintains lubrication; decolorization removes oxides and colored substances, restores the oil's appearance, extends its service life, and ensures stable operation of mechanical systems.

[0003] In most existing base oil production facilities, the products will turn black during operation, which seriously affects the product quality, greatly reduces the economic value of the product, and consequently fails to meet the market demand for high-quality lubricating base oils.

[0004] Therefore, it is necessary to provide a new lubricating oil filtration and decolorization device to solve the above-mentioned technical problems. Utility Model Content

The other end of the conveying pipe 8 is fixedly connected to one side of the filter 3. One end of the conveying pipe 8 is fixedly connected to the output end of the raw material conveying pump 7. A discharge pipe 13 is fixedly connected inside the product tank 11 on the side away from the product conveying pump 12. An overflow pipe 15 is fixedly connected to one side of the top of the filter 3. The end of the overflow pipe 15 away from the filter 3 is fixedly connected to the inside of one side of the auxiliary agent tank 5. The discharge pipe 13 is connected to the filter 3 through the first and second valves 14. A filter circulation pipe 19 is fixedly connected inside the top of the raw material tank 6. The unloading pump 9 is used to remove internal gas during filter cleaning. The unloading pump 9 is installed on the filter 3. A support platform 10 is fixedly connected to the top right of the base plate 1. A product tank 11 is fixedly connected to the top of the support platform 10. A product transfer pump 12 is installed on one side bottom of the product tank 11. The bottom of the product transfer pump 12 is fixedly connected to the top of the support platform 10. A pipe is fixedly connected to the output end of the product transfer pump 12. An auxiliary agent transfer pump 16 is fixedly connected to the bottom of the auxiliary agent tank 5. A transmission pipe 17 is fixedly connected to the output end of the auxiliary agent transfer pump 16. The other end of the transmission pipe 17 is connected to the transmission pipe 8 through a one-way valve 18. The end of the filter circulation pipe 19 away from the raw material tank 6 is connected to the overflow pipe 15 through a second valve 20. Under normal circumstances, the second valve 20 is closed. The second valve 20 will only open during circulation. The bottom plate 1 has a storage trough 21 located directly below the filter 3. A slag receiving trolley 22 is installed on the storage trough 21.

[0021] The working principle of the lubricating oil filtration and decolorization device provided by this utility model is as follows: First, start the raw material delivery pump 7. The lubricating oil raw material in the raw material tank 6 is delivered to the filter 3 through the delivery pipe 8. During this process, some raw material enters the additive tank 5 through the overflow pipe 15 to start building up the liquid level. This step is to store a certain amount of lubricating oil raw material in the additive tank 5 so that the additive can be added and mixed later. Once the liquid level in the additive tank 5 reaches a suitable height, a certain amount of additive is added to the additive tank 5. Then, the internal agitator is started to mix the additive with the lubricating oil raw material evenly, so that the additive is fully dispersed in the lubricating oil. Then, the additive delivery pump 16 is started, and the additive slurry in the additive tank 5 is sent into the filter 3 through the transfer pipe 17. The material returns to the additive tank 5 through the overflow pipe 15. At this time, the second valve 20 is closed, and the overflow pipe 15 and the filter circulation pipe 19 are blocked, forming a pre-coating circulation. During the pre-coating circulation, the additive gradually forms a pre-coating layer on the filter plate in the filter 3. This pre-coating layer helps to filter impurities and decolorize more effectively in the future. The pre-coating circulation continues for a certain period of time to allow the pre-coating layer to fully form and stabilize. After the pre-coating cycle is completed, the second valve 20 is opened, and the liquid in the overflow pipe 15 cannot be delivered to the additive tank 5, but can only be delivered to the filter circulation pipe 19. At this time, the material will return to the raw material tank 6. Then the raw material delivery pump 7 is started again to send the raw material in the raw material tank 6 into the filter 3. At this time, the filtered material returns to the raw material tank 6 through the filter circulation pipe 19, forming a filtration cycle. During the filtration cycle, impurities in the lubricating oil are intercepted by the filter disc in the filter 3, and the additives decolorize the lubricating oil. After a period of filtration cycle, when it is confirmed that the filtration effect has reached a certain level, the first and second valves 14 are opened, and the filtered product enters the product tank 11 for storage through the discharge pipe 13 and the first and second valves 14. During cleaning, the copper drum opens the bottom valve of filter 3 to throw out the filter aid layer and filter cake on the filter plate of filter 3, so that they fall into the slag receiving trolley 22 below. After cleaning, the bottom valve of filter 3 is closed, and the filter 3 is replaced with gas by the unloading pump 9 to remove any impurities that may remain inside, in preparation for the next filtration operation. Repeat the above steps to decolorize and filter the new lubricating oil raw materials, continuously producing lubricating oil products that meet quality requirements. When it is necessary to send the filtered material out, start the product delivery pump 12 to transport the lubricating oil in the product tank 11 to the designated delivery location through the connecting pipeline, thus completing the entire production process.
