Description

Technical Field

[0001] This invention relates to the field of bag filter dust collection equipment technology, specifically to a high-antioxidant ether ester lubricating oil processing device. Background Technology

[0002] The oxidation process of lubricating oil is a complex, multi-step process involving the reaction of its main component, hydrocarbons, with oxygen. The reaction products include intermediates such as alcohols, aldehydes, ketones, and acids, and final products such as gums and precipitates. In the reaction, active free radicals react with oxygen to initially generate intermediates such as alcohols, aldehydes, ketones, and acids. Further oxidation then produces complex hydroxyl-containing molecules (hydroxy acids) or esters formed by the combination of alcohols and organic acids. Esterification of alcohols and acids can combine two compounds into a large molecule. As oxidation progresses, the molecular weight of the products continuously increases, and their structures become more complex, ultimately forming gums and solid precipitates.

[0003] In existing technologies, the final products of oxidation in lubricating oil during use have two directions: one is the formation of acidic substances (such as carboxylic acids, hydroxy acids, asphaltic acid, etc.) and ester intermediates, with the final product being carbonaceous matter; the other is the formation of gums and asphaltenes, with the final product being semi-oil coke. Hydroxy acids, semi-lactides, and asphaltic acid are slightly soluble in lubricating oil, and the precipitated portion is a viscous substance that easily adheres to metal surfaces, transforming into a varnish-like substance at high temperatures. Asphaltenes, semi-oil coke, and carbonaceous matter, on the other hand, are suspended in the oil as fine particles of dark brown or black solid powder; when they aggregate into larger particles, they can precipitate from the oil. Therefore, it is evident that deeply oxidized lubricating oil has an increased oxygen content and a larger molecular weight, transforming from hydrocarbon compounds into non-hydrocarbon compounds; its appearance becomes darker, with more sediment and increased corrosivity, thus significantly reducing the performance of the lubricating oil. Furthermore, existing mixing devices, with their fixed stirring rod height and stirring radius, cannot uniformly mix the raw materials. Therefore, this invention proposes a processing method for high-antioxidant ether ester lubricating oil to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a high-antioxidant ether ester lubricating oil processing device to address the issue mentioned in the background art where the final products of lubricating oil oxidation have two directions: one direction is the formation of acidic substances (such as carboxylic acids, hydroxy acids, asphaltic acid, etc.) and ester intermediates, with the final product being carbonaceous material; the other direction is the formation of gums and asphaltenes, with the final product being semi-oil coke. Hydroxy acids, semi-lactides, and asphaltic acid are slightly soluble in lubricating oil, and the precipitated portion is a viscous substance that easily adheres to metal surfaces and transforms into a varnish-like substance at high temperatures. Asphaltenes, semi-oil coke, and carbonaceous material, on the other hand, are suspended in the oil as fine particles in the form of dark brown or black solid powders, and can precipitate from the oil when they aggregate into larger particles. Therefore, it is evident that deeply oxidized lubricating oil has an increased oxygen content and a larger molecular weight, transforming from hydrocarbon compounds into non-hydrocarbon compounds; its appearance becomes darker, with increased sediment and increased corrosivity, thus significantly reducing the performance of the lubricating oil. Meanwhile, existing mixing devices have a fixed height of the mixing rod and a fixed mixing radius when mixing raw materials, which makes it impossible to mix the raw materials evenly.

[0085]

[0086] Example 3:

[0087] Comparative example:

[0088] 1. Using existing technology as a comparative example, this illustrates how the solution of the present invention solves the problems of the prior art.

[0089] This solves the technical problem of poor antioxidant properties in existing synthetic base lubricants.

[0090] 2. Use a control experiment as a comparative example. For example, if the reaction temperature is 20~50℃, you can provide an experimental plan for a reaction temperature outside the range of 20~50℃.

[0091] Example of prior art comparison:

[0092] Ether-based synthetic base oils: 49.00%;

[0093] Ester-based synthetic base oils: 50.00%;

[0094] Anti-wear agent 0.20%;

[0095] Antioxidant 0.80%;

[0096] Demulsifier 50ppm;

[0097] Defoamer 50ppm.

[0098] A comprehensive comparative analysis of schemes 1-3 and the control case was conducted, and the results are shown in Table 2:

[0099]

[0100] The data in the figure shows that, compared with existing comparative examples of major oils on the market, the high-antioxidant ether ester lubricating oil provided in this application has a lower acid value in the TOST test of synthetic hydraulic oil, indicating that its antioxidant performance is superior. This is due to the synergistic effect of antioxidants and metal passivators. During use, when the oil comes into contact with metal or contains metal ions, oxidation is accelerated. The mechanism of metal passivators is to react with metal ions to form chelates or to form a protective barrier film on the metal surface, thereby preventing the metal from catalyzing the oxidation of the oil and thus enhancing its antioxidant performance.

[0101] When this device is working, the raw materials are sequentially fed into the interior of the vessel 1 through the feed port 15 according to the proportion. Then, the heating device 13 is started to maintain the temperature inside the vessel 1 at the value required for the test. At the same time, the motor 14 is started to drive the drive shaft 21 to rotate the fixed sleeve 22. Meanwhile, the adjusting ring 24 on the inner wall of the fixed sleeve 22 slides back and forth in cooperation with the adjusting groove 221 and the reciprocating thread groove 231 on the fixed rod 23. While sliding, the outer adjusting sleeve 26 adjusts the angle of the stirring rod 25 back and forth, so that the height and angle of multiple stirring rods 25 can be cyclically adjusted during the stirring process to improve the uniformity of the stirring and make the mixing more uniform.
