A driving member 12 for driving the rotating tube 7, the spiral blade 8, the vertical rod 9, the horizontal scraping strip 10 and the oblique scraping strip 11 to rotate is arranged on the support plate 5. The driving member 12 comprises a motor 121 fixedly mounted on the support plate 5, a gear 122 rotatably arranged on the bottom surface of the support plate 5, and a gear 2 123 fixedly mounted on the outer wall of the rotating tube 7. The output shaft end of the motor 121 is fixedly mounted on the rotating shaft end of the gear 122, and the gear 122 is meshed and drivenly connected with the gear 2 123. A vertical scraping strip 15 is fixedly mounted on the top of the vertical rod 9, and the horizontal scraping strip 10, the oblique scraping strip 11 and the vertical scraping strip 15 are all provided with rubber strips.

[0021] When in use, the feeding pipe 6, the rotating pipe 7 and the feeding port 2 are used to transport the lubricating oil. During the lubricating oil transportation process, the motor 121 on the support plate 5 is started, and the output shaft of the motor 121 rotates to drive the gear 1 122 to rotate. Since the gear 1 122 is meshed with the gear 2 123, the gear 1 122 will drive the gear 2 123 and the rotating pipe 7 fixed thereto to rotate, and the spiral blade 8 in the rotating pipe 7 will rotate accordingly, so that the lubricating oil is conveniently drawn in and pushed downward to the filter screen 4 in the box body 1. After the lubricating oil is filtered by the filter screen 4, the pure oil falls through the filter screen 4, and the impurities are intercepted by the filter screen 4;

[0022] The spiral blade 8 rotates while driving the vertical rod 9 to rotate. The horizontal scraping bar 10, the oblique scraping bar 11 and the vertical scraping bar 15 on the vertical rod 9 rotate with the vertical rod 9. The horizontal scraping bar 10 continuously scrapes on the surface of the filter 4 to prevent the lubricating oil on the filter 4 from flowing slowly. The oblique scraping bar 11 and the vertical scraping bar 15 scrape on the inner wall of the box body 1 to prevent the lubricating oil from accumulating on the inner wall of the box body 1. The rubber strips sleeved on these scraping bars are soft and elastic, which can effectively protect the surface of the filter 4 and the inner wall of the box body 1. The bottom of the box body 1 is set to an inclined shape to facilitate the discharge of the filtered lubricating liquid from the discharge port 3. The rotation of the oblique scraping bar 11 can also improve the discharge effect.

[0023] The lubricating oil filtering device has the characteristics of being easy to load, filter and discharge the lubricating oil, can effectively improve the filtering efficiency and filtering effect, and the overall structure of the device is simple, easy to operate and highly practical.

[0024] The filter screen 4 has an annular opening 13 at the top edge thereof;

[0025] The annular opening 13 on the edge of the filter 4 helps to guide the scraped impurities to the edge of the box 1 when the scraper scrapes the surface of the filter 4, preventing the impurities from accumulating in the center of the filter 4, further ensuring the filtering effect and service life of the filter 4.

[0026] The feeding tube 6 is provided with a heating part 14, and a heating resistance wire is provided in the heating part 14;

[0027] The heating resistance wire in the heating part 14 generates heat after being energized, thereby heating the lubricating oil in the feeding pipe 6. The fluidity of the heated lubricating oil is enhanced, the viscosity is reduced, and it is easier to flow quickly through the pushing action of the spiral blades 8. This not only improves the feeding efficiency, but also helps to separate impurities during the filtration process.

[0028] The box body 1 is provided with a controller, and the controller is electrically connected to the motor 121 and the heating resistance wire respectively;

[0029] The controller is electrically connected to the motor 121 and the heating resistance wire. The speed of the motor 121 and the heating temperature of the heating resistance wire can be conveniently adjusted through the controller. According to the properties of the lubricating oil and the filtering requirements, the operator can flexibly adjust the working state of the device through the controller to achieve the best filtering effect and efficiency.

[0030] Working principle:

[0031] When in use, the feeding pipe 6, the rotating pipe 7 and the feeding port 2 are used to transport the lubricating oil. During the lubricating oil transportation process, the motor 121 on the support plate 5 is started, and the output shaft of the motor 121 rotates to drive the gear 1 122 to rotate. Since the gear 1 122 is meshed with the gear 2 123, the gear 1 122 will drive the gear 2 123 and the rotating pipe 7 fixed thereto to rotate, and the spiral blade 8 in the rotating pipe 7 will rotate accordingly, so that the lubricating oil is conveniently drawn in and pushed downward to the filter screen 4 in the box body 1. After the lubricating oil is filtered by the filter screen 4, the pure oil falls through the filter screen 4, and the impurities are intercepted by the filter screen 4;

[0032] The spiral blade 8 rotates while driving the vertical rod 9 to rotate. The horizontal scraping bar 10, the oblique scraping bar 11 and the vertical scraping bar 15 on the vertical rod 9 rotate with the vertical rod 9. The horizontal scraping bar 10 continuously scrapes on the surface of the filter 4 to prevent the lubricating oil on the filter 4 from flowing slowly. The oblique scraping bar 11 and the vertical scraping bar 15 scrape on the inner wall of the box body 1 to prevent the lubricating oil from accumulating on the inner wall of the box body 1. The rubber strips sleeved on these scraping bars are soft and elastic, which can effectively protect the surface of the filter 4 and the inner wall of the box body 1. The bottom of the box body 1 is set to an inclined shape to facilitate the discharge of the filtered lubricating liquid from the discharge port 3. The rotation of the oblique scraping bar 11 can also improve the discharge effect.

[0033] The annular opening 13 on the edge of the filter 4 helps to guide the scraped impurities to the edge of the box 1 when the scraper scrapes the surface of the filter 4, preventing the impurities from accumulating in the center of the filter 4, further ensuring the filtering effect and service life of the filter 4;

[0034] The heating resistance wire in the heating part 14 generates heat after being energized, and heats the lubricating oil in the feeding pipe 6. The heated lubricating oil has enhanced fluidity and reduced viscosity, and is easier to flow quickly through the pushing action of the spiral blades 8, which not only improves the feeding efficiency, but also helps to separate impurities during the filtration process;

[0035] The controller is electrically connected to the motor 121 and the heating resistance wire. The speed of the motor 121 and the heating temperature of the heating resistance wire can be conveniently adjusted through the controller. According to the properties of the lubricating oil and the filtering requirements, the operator can flexibly adjust the working state of the device through the controller to achieve the best filtering effect and efficiency.

[0036] The lubricating oil filtering device has the characteristics of being easy to load, filter and discharge the lubricating oil, can effectively improve the filtering efficiency and filtering effect, and the overall structure of the device is simple, easy to operate and highly practical.
