[0002] At present, when filtering waste lubricating oil, filter paper is mostly used for filtering. Due to the special properties of lubricating oil, the smaller the pores of the filter paper used, the lower the flow capacity. Considering the time-consuming filtration of filter paper, filter paper with smaller pores is often not used. As a result, after filtration, there are still a small amount of ferromagnetic fine impurities in the waste lubricating oil. If the ferromagnetic fine impurities are used directly, it is very easy to cause great wear and tear on the inside of the equipment. Therefore, a multi-stage filtration device for waste lubricating oil regeneration is designed to solve the problem that the current waste lubricating oil filtration device cannot effectively filter ferromagnetic fine impurities.

The output end of the drive motor 1 is embedded in the connecting hole 9. A screw 11 is provided on the side of the connecting plate 6 and relative to the output end of the drive motor 1. The screw 11 penetrates the connecting plate 6 and is embedded in the output end of the drive motor 1. The magnet 4 is fixedly installed inside the side of the connecting plate 6 away from the drive motor 1. Through holes 12 are symmetrically provided on the surface of the connecting plate 6 and relative to the position of the magnet 4 at equal intervals. An inspection port 7 is provided on the outer wall of the main shell 8 and located between the drive motors 1. The height of the inspection port 7 is greater than the thickness of the connecting plate 6.

[0020] Through the above technical scheme: when in use, the waste lubricating oil is filtered through the filter element above, and after removing most of the impurities, it enters the lower part of the main shell 8, and the connecting plate 6 is driven to rotate by the driving motor 1, driving the magnet 4 to move back and forth inside the waste lubricating oil, and the through hole 12 is used to increase the contact between the magnet 4 and the lubricating oil, so that the magnet 4 adsorbs and fixes the magnetic fine impurities inside the waste lubricating oil on the connecting plate 6, thereby solving the problem that the current waste lubricating oil filtering device cannot effectively filter ferromagnetic fine impurities. After long-term use, by opening the inspection port 7, the operator's hand can extend through the inspection port 7 to the vicinity of the screw 11, rotate the screw 11, release the fixed connection between the connecting plate 6 and the driving motor 1, and take out the connecting plate 6 through the inspection port 7, and then clean it, ensuring the adsorption effect of magnetic fine impurities during long-term use.

[0021] See also Figure 1-Figure 4As shown, a water-blocking tray 3 is installed at the end of the driving motor 1, and a connecting block 10 is provided in the middle of the outer wall of the water-blocking tray 3. A fixing hole 13 is opened in the middle of the end face of the connecting block 10, and a screw 11 passes through the connecting plate 6 and is embedded in the fixing hole 13. The connecting block 10 and the connecting hole 9 are both rectangular structures, and the thickness of the connecting block 10 is less than the thickness of the connecting plate 6. The side wall of the connecting plate 6 is in contact with the outer wall of the water-blocking tray 3. A placing plate 2 is installed on the outer wall of the main shell 8 and below the driving motor 1. The placing plate 2 is a concave structure, and an electric valve 5 is installed on the discharge port of the main shell 8.

[0022] Through the above technical solution: during installation, the connecting plate 6 is moved horizontally to force the connecting block 10 to be embedded in the connecting hole 9, and the side wall of the connecting plate 6 is made to contact with the water-blocking plate 3. While the water-blocking plate 3 is used to prevent the leakage of lubricating oil, it is convenient for the user to position and install the connecting plate 6, and the installation steps are simplified. The setting of the rectangular structure of the connecting block 10 and the connecting hole 9 reduces the problem of the connecting plate 6 rotating on its own during installation, thereby improving the installation efficiency. In addition, by adjusting the opening and closing gap of the electric valve 5, the contact time between the lubricating oil and the magnet 4 can be extended, thereby achieving the purpose of further reducing the residual magnetic fine impurities.
