[0002] In modern industrial production, hydraulic systems are widely used in various fields, such as machinery manufacturing and engineering construction. As the working medium of a hydraulic system, the quality of hydraulic oil directly affects the performance and reliability of the hydraulic system.

[0003] Currently, filtration is a crucial step in the production of hydraulic oil. Existing hydraulic oil filtration devices have some shortcomings. Due to their limited filtration precision, they cannot completely remove tiny particles from the hydraulic oil. This can lead to accelerated wear, blockages, and leaks in the hydraulic system during operation, reducing system efficiency and lifespan. Furthermore, some filtration devices have complex structures, making operation and maintenance inconvenient. In actual production, this not only increases equipment costs but may also increase the probability of malfunctions due to the complex structure, thus affecting production schedules.

[0004] In summary, in order to meet the requirements of modern industry for high-quality, high-efficiency, and high-precision filtration of hydraulic oil, it is necessary to design a new type of hydraulic oil production fine filtration device to overcome the shortcomings of existing filtration devices and improve the filtration effect and production efficiency of hydraulic oil.

[0020] This utility model provides a hydraulic oil production fine filtration device as shown in the figure, including a tank body 1, a tank cover 2, a feed inlet 3, and a discharge outlet 4. The device is characterized in that: a tank cover 2 is provided on top of the tank body 1, and the tank cover 2 fits snugly against the tank body 1; a reduction motor 5 is located at the center of the tank cover 2; the output end of the reduction motor 5 is fixedly connected to one end of a stirring shaft 6; the other end of the stirring shaft 6 extends through into the tank body 1; a first sealing plate 7 is fixedly provided on the stirring shaft 6; the upper and lower ends of the first sealing plate 7 have circular sealing structures to prevent hydraulic oil from entering from the upper and lower ends; a first filter screen 8 is provided inside the first sealing plate 7; the first filter screen 8 has a cylindrical snap-fit ​​design. At the upper and lower ends of the sealing plate 7, a first scraper 9 is provided on the outer side of the first filter screen 8. The first scraper 9 has an L-shaped structure and one side is attached to the first filter screen 8. The upper and lower ends of the first scraper 9 are fixedly connected to the first sealing plate 7. As the first sealing plate 7 rotates, it cleans and scrapes off the impurity particles on the outer side of the first filter screen 8. A stirring assembly 10 is provided below the first sealing plate 7, and a fine filter assembly 11 is provided inside the first sealing plate 7. A discharge port 3 is provided below the fine filter assembly 11, from which the finely filtered hydraulic oil flows out.

[0021] The stirring assembly 10 includes a support plate 101 and a square stirring rod 102. The support plate 101 is circular and fixedly disposed below the first sealing plate 7. The support plate 101 is fixedly connected to the inner wall of the tank 1, effectively separating the hydraulic oil and allowing the hydraulic oil to move above the support plate 101. The square stirring rod 102 is disposed above the support plate 101. One end of the square stirring rod 102 is fixedly connected to the first sealing plate 7 and rotates with the first sealing plate 7.

[0023] Working principle: First, the hydraulic oil to be finely filtered is poured into the tank 1 through the feed inlet 3. Then, the geared motor 5 is started to drive the first scraper 9 and the square stirring rod 102 to stir and rotate. The hydraulic oil begins to flow into the first filter screen 8 from the outside of the first sealing plate 7. The first scraper 9 adheres to the first filter screen 8, and the filtered residue particles are cleaned in time. Then the hydraulic oil undergoes a first filtration. After that, it undergoes a second filtration through the second filter screen 112. Under the rotation of the second scraper 113, the hydraulic oil filtered for the second time is quickly discharged from the discharge port 4.
