Description

Technical Field

[0001] The utility model relates to the technical field of purification devices, in particular to an industrial lubricating oil purification device. Background Art

[0002] Industrial lubricants are lubricants used in various industrial equipment and machinery to reduce friction, wear and heat generation. They are usually composed of base oils and additives. Additives are used to enhance the performance of lubricants, such as anti-oxidation, anti-wear and anti-corrosion. There are many types of industrial lubricants, including hydraulic oil, gear oil, compressor oil, guide oil, vacuum pump oil, etc. Correct selection and use of industrial lubricants can extend the service life of equipment and improve production efficiency. During production, industrial lubricants need to pass through purification devices to purify their impurities.

[0003] When purifying industrial lubricating oil, the existing industrial lubricating oil purification device usually adds a catalyst to react with impurities in the industrial lubricating oil, and then filters out the impurities. However, during the reaction, the waste gas generated cannot be discharged, which may cause the waste gas to be re-mixed into the lubricating oil, resulting in lower quality of the lubricating oil. In addition, since the lubricating oil is relatively viscous, the discharge rate is slow during discharge, and it will be adsorbed to the inner wall of the purification device. When filtering the lubricating oil, the existing filtering device is usually fixed, and it is impossible to increase or decrease the filter screen according to demand. It is also inconvenient to disassemble the filter screen when it needs to be cleaned. Therefore, an industrial lubricating oil purification device is proposed to address the above problems.
