[0002] At present, during the production process of lubricating oil, iron filings and impurities are generally contained in the lubricating oil. Such lubricating oil containing impurities will cause serious wear of parts, and long-term use will damage the entire system. Therefore, manufacturers generally filter the lubricating oil before filling it into barrels. According to the publication number: CN220004404U, a sediment-proof filtering device for lubricating oil processing is disclosed, including: a filtering barrel body; a cooling component, the bottom of the cooling component is fixedly connected to the bottom of the inner wall of the filtering barrel body, the cooling component includes a first placement box, the bottom of the first placement box is fixedly connected to the bottom of the inner wall of the filtering barrel body, a first motor is fixedly connected to the bottom of the inner wall of the first placement box, and a fan protection net is fixedly connected to the top of the first placement box. The utility model provides a sediment-proof filtering device for lubricating oil processing. By turning on the first motor, the rotation of the first motor drives the fan blades to rotate, blowing the air flow towards the condensation tube, and the cold air flow blows towards the partition plate to cool the oil liquid in the partition plate. The lubricating oil after the cooling treatment is convenient for cooling the machine, ensuring the safe operation of the machine, increasing the viscosity of the lubricating oil to ensure the viscosity, preventing the oil liquid from leaking due to being too thin, and increasing the service life of the lubricating oil. However, the above technology still has some defects. For example, the filter screen of the existing filtering device cannot be quickly exported for cleaning, so that impurities are easily accumulated on the filter screen, resulting in poor filtering effect on the lubricating oil in subsequent work, and the practicability is poor, and improvement is needed.

A soft pad 32 is fixedly installed at the top end of the clamping rod 31. A pulling block 33 is fixedly installed on the surface of the clamping rod 31, which better supports the pipeline 1. Before use, first place the pipeline 1 inside the bracket 24, then pinch the upper clamping plate 27 and pull it backward, so that the upper clamping plate 27 rotates backward at the top end of the bracket 24 through the hinge 26. When the bottom end of the upper clamping plate 27 touches the top end of the bracket 24, it is okay. Then pinch the pulling block 33, align the clamping rod 31 with the upper sliding groove 30 and push it inward, so that the clamping rod 31 slides inward on the surface of the convex block 29 through the sliding groove 30. When the clamping rod 31 completely slides into the inside of the sliding groove 30, it is okay. And at this time, the clamping rod 31 slides into the inside of the bracket 24 through the clamping groove 25, and the soft pad 32 firmly clamps the upper clamping plate 27 at the top end of the bracket 24 through the fixing plate 28, thereby preventing the situation where the pipeline 1 falls off due to insecure fixation during use. The upper clamping plate 27 is rotatably connected to the pipeline 1, the fixing plate 28 is slidably connected to the pipeline 1, the clamping rod 31 is slidably connected to the convex block 29, the clamping rod 31 is slidably connected to the bracket 24, and the clamping rod 31 is slidably connected to the clamping groove 25, which makes it more convenient for the clamping rod 31 to slide and avoids the situation where the clamping rod 31 is stuck by the convex block 29 or the bracket 24 and cannot slide continuously during use.,

[0028] Working principle: When in use, first place the bracket 24 at the required position, then place the pipeline 1 inside the bracket 24, and then pinch the upper clamping plate 27 and pull it backward, so that the upper clamping plate 27 rotates backward at the top of the bracket 24 through the hinge 26. When the bottom end of the upper clamping plate 27 touches the top of the bracket 24, it is okay. At this time, the upper clamping plate 27 drives the convex block 29 to slide onto the surface of the bracket 24 through the fixing plate 28. Then pinch the pulling block 33 and push the clamping rod 31 corresponding to the upper chute 30 backward, so that the clamping rod 31 completely slides into the inside of the convex block 29 through the chute 30. When the clamping rod 31 completely slides into the inside of the convex block 29, it is okay, and it completely slides into the inside of the bracket 24 through the clamping groove 25. At this time, the soft pad 32 firmly clamps the clamping rod 31 inside the convex block 29 and fixes the pipeline 1, thereby preventing the pipeline 1 from falling off due to being unstable during use. And after long-term use, when it is necessary to clean the filter screen B21 and the filter screen A12, you can pinch the rotating handle A9 and rotate it, so that the threaded rod A8 rotates outward through the rotating groove A4 inside the fixing block 3. When the threaded rod A8 completely rotates out of the inside of the fixing block 3 and the side block A2 through the rotating groove A4, it can be taken out from the inside of the side block B6 through the fixing groove 7. Then remove the cover plate 5 from the side of the pipeline 1.

And the right side of the fixing ring A11 is far away from the left side of the limiting plate 10. When the fixing ring B20 and the fixing ring A11 completely slide out of the inside of the pipeline 1, it is okay. Then pinch the rotating handle B19 and rotate it. When the threaded rod B18 rotates out of the inside of the clamping block 14 through the rotating groove B15, it can be taken out from the inside of the mounting block 16 through the mounting groove 17. Then after taking out the clamping block 14 from the inside of the mounting block 16, the filter screen B21 and the filter screen A12 can be cleaned for continued use later.
