[0024] Embodiment 1

[0025] See also Figures 1 to 3 The utility model provides a technical solution: a rubber oil seal body 1, a rotating shaft 2 is inserted inside the rubber oil seal body 1, an absorption groove 3 is respectively opened on the top surface and the bottom surface of the rubber oil seal body 1, a plurality of mounting grooves 4 are opened on the inner bottom surface of the absorption groove 3, a micro fan 5 is fixed inside the mounting groove 4, the micro fan 5 is electrically connected to the external control device, and a filter screen 6 is arranged inside the absorption groove 3.

[0026] Through the operation of the micro fan 5, the generated dust is absorbed into the absorption tank 3. During the absorption, the larger impurities and dust are first filtered out through the filter 6. When the dust in the filter 6 and the absorption tank 3 accumulates to a certain amount, the filter 6 is removed, and the absorbed dust and accumulated impurities can be cleaned up in a centralized manner, thereby avoiding the accumulation of dust and impurities on the outer wall of the rotating shaft 2, thereby preventing the long-term accumulation of dust from entering the rubber oil seal body 1, avoiding affecting the stable operation of the equipment, and facilitating the subsequent cleaning of the staff, saving time and improving efficiency.

[0027] Embodiment 2

[0028] Based on the first embodiment, dust rings 7 are fixed to the top and bottom surfaces of the rubber oil seal body 1 respectively, and two contact rings 8 are fixed inside the rubber oil seal body 1. The contact rings 8 are in contact with the outer wall of the rotating shaft 2, and the inner wall of the contact rings 8 is provided with guide grooves 9.

[0029] The dust ring 7 fits tightly with the rotating shaft 2, thereby effectively preventing dust from entering the interior of the rubber oil seal body 1. The contact ring 8 can make the rotating shaft 2 more stable during operation to avoid shaking and lubricating oil leakage. The guide groove 9 can evenly distribute the lubricating oil in the rubber oil seal body 1, thereby making the rotating shaft 2 smoother during operation.

[0030] Embodiment 3

[0031] On the basis of the second embodiment, two placement plates 10 are fixed inside the absorption tank 3, and a plug hole 11 is opened on the top surface of the placement plate 10. Two plug posts 12 are fixed on the bottom surface of the filter screen 6. The plug posts 12 are movably inserted into the plug holes 11. The dust ring 7 is made of elastic material, and the opening of the dust ring 7 is in contact with the outer wall of the rotating shaft 2. The placement plate 10 is arc-shaped, and the thickness of the placement plate 10 is one third of the thickness of the absorption tank 3.

[0032] The filter 6 can be easily and conveniently removed through the socket 11 and the pin 12, which makes it faster to clean and saves time and energy. The elastic material can make the dust prevention effect better and is also convenient for taking. The thickness of the placement plate 10 can avoid occupying too much space in the absorption tank 3, thereby increasing the dust storage capacity.

[0033] When the utility model is in use, the staff installs the rubber oil seal body 1 on the rotating shaft 2, and then starts to operate and use it. Dust will be generated during use. When the dust falls, the generated dust is absorbed into the absorption tank 3 through the operation of the micro fan 5. During the absorption, the larger impurities and dust are first filtered out through the filter 6. When the dust in the filter 6 and the absorption tank 3 accumulates to a certain amount, the filter 6 is removed, and the absorbed dust and accumulated impurities can be centrally cleaned, thereby avoiding the accumulation of dust and impurities on the outer wall of the rotating shaft 2, thereby preventing the long-term accumulated dust from entering the rubber oil seal body 1, avoiding affecting the stable operation of the equipment, and also facilitating the subsequent cleaning of the staff, saving time and improving efficiency.
