Description

Technical Field

[0001] The utility model relates to the technical field of oil filters, in particular to an oil filter with a centrifugal separation structure. Background Art

[0002] The centrifugal oil filter utilizes the high-speed rotation of its centrifugal head to quickly separate the oil, water and impurities in the lubricating oil with different degrees of pollution under the action of different centrifugal forces. After searching, the patent with the announcement number CN206338097U discloses a centrifugal oil filter, including a body, a cover body provided on the top of the body, an oil pipe installed in the middle of the cover body, a first bolt mounting platform provided on the top of the body, a second bolt mounting platform correspondingly provided at the bottom of the cover body, the second bolt mounting platform and the first bolt mounting platform are fixed by bolts, and the edges of the first bolt mounting platform or / and the second bolt mounting platform are provided with barbs, and the inner side of the barbs forms an oil storage space. After the oil enters the filter, the centrifugal movement will throw the oil impurities to the barbs, thereby storing the impurities in the oil storage space, improving the filtering effect, making the filtered oil cleaner, and having a good lubrication effect, ensuring the lubrication of the engine bearings. When the centrifugal oil filter device processes the impurities inside the oil too much, the impurities will accumulate inside the guide hook. The internal space of the guide hook is limited. Long-term use will easily cause internal blockage of the guide hook, causing the subsequently filtered impurities to move with the movement of the oil, reducing the filtering efficiency of the device.

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] Example 1: Please refer to Figure 1-3 The utility model embodiment provides an oil filter with a centrifugal separation structure, including an oil inlet tank 1 and a rotating tube 10. A base 5 is arranged below the oil inlet tank 1. The top surface of the base 5 is fixedly connected to an oil inlet pipe 6. An oil inlet hole 7 is arranged inside the right side wall of the oil inlet pipe 6. The rotating tube 10 is rotatably connected to the inside of the oil inlet tank 1. A driving motor 4 is fixedly installed on the top surface of the oil inlet tank 1. The output shaft of the driving motor 4 is fixedly connected to the top of the rotating tube 10 by passing through the inside of the oil inlet tank 1. A plurality of oil outlet holes 11 are arranged at equal intervals inside the side walls on both sides of the upper end of the rotating tube 10. The lower end of the rotating tube 10 passes through the oil inlet tank 1. The bottom surface is rotatably connected with the upper end of the oil inlet pipe 6, and the tube wall of the rotating tube 10 is rotatably sleeved with a filter element 8, the bottom surface of the filter element 8 is sealed, and the top of the filter element 8 is higher than the position of the oil outlet hole 11 in the rotating tube 10. The engine oil is input into the interior of the rotating tube 10 through the oil inlet hole 7 of the oil inlet pipe 6. At the same time, the driving motor 4 is turned on to rotate the rotating tube 10, and the oil entering the rotating tube 10 will also be thrown out to the outside through the oil outlet hole 11, so that the engine oil enters the interior of the filter element 8, and the impurities in the engine oil can be attached to the filter element 8. When the input engine oil overflows the interior of the filter element 9, it moves to the bottom of the filter element 8 through the outside of the filter element 8.

[0017] Embodiment 2: In this embodiment, as Figure 1-3 As shown, the outer side wall of the filter element 8 is fixedly sleeved with a filter plate 9, and an oil storage bin is formed between the filter plate 9 and the bottom surface of the oil inlet tank 1. The outer side wall of the filter plate 9 is tightly fitted to the inner side wall of the oil inlet tank 1 through a sealing gasket. When the engine oil overflows from the outside of the filter element 8, the engine oil passes through the filter plate 9 and enters the bottom of the filter plate 9 to strengthen the filtering of the engine oil. Oil outlet pipes 2 are symmetrically fixedly installed on the side walls of the oil inlet tank 1 on both sides. The oil outlet pipes 2 are both L-shaped and are connected to the interior of the oil inlet tank 1. An oil drain pipe 3 is fixedly connected between the upper ends of the oil outlet pipes 2. The position where the lower end of the oil outlet pipe 2 is connected to the oil inlet tank 1 is below the filter plate 9. After the engine oil enters below the filter plate 9, the engine oil moves through the oil outlet pipes 2 on both sides, so that the engine oil moved to the oil outlet pipe 2 is discharged through the oil drain pipe 3.

[0018] It should be noted that, in this embodiment, when using an oil filter with a centrifugal separation structure, Figure 1-3As shown, the engine oil is input into the interior of the rotating tube 10 through the oil inlet hole 7 of the oil inlet pipe 6, and the driving motor 4 is turned on to rotate the rotating tube 10. The oil entering the rotating tube 10 is also thrown out to the outside through the oil outlet hole 11, so that the engine oil enters the interior of the filter element 8, and the impurities in the engine oil can be attached to the filter element 8. When the input engine oil overflows the interior of the filter element 9, it moves to the bottom of the filter element 8 through the outside of the filter element 8, and the engine oil passes through the filter plate 9 and enters the bottom of the filter plate 9, thereby strengthening the filtering of the engine oil. At this time, the completely filtered engine oil passes through the filter plate 9 and enters the lower part of the filter plate 9, and moves through the oil outlet pipes 2 on both sides, so that the engine oil moved to the oil outlet pipe 2 is discharged through the oil drain pipe 3.
