[0026] As Figures 1-4 The utility model discloses a hydraulic oil filter, including filter drum 1, multilayer filter assembly, filter hole cleaning assembly and quick filter assembly: the top of filter drum 1 is connected with feed inlet, is seted up with the discharge port at filter drum 1 bottom, multilayer filter assembly includes the metal filter plate 2, activated carbon fiber filter plate 3 and high-precision filter plate 4 of fixed connection in the inner wall of filter drum 1, is seted up with a plurality of filter holes on metal filter plate 2, the top of filter drum 1 is rotatably connected with rotating shaft 5, and the middle part of metal filter plate 2, activated carbon fiber filter plate 3 and high-precision filter plate 4 are fixedly installed with sealed bearing, and the inboard of sealed bearing in the middle part of metal filter plate 2, activated carbon fiber filter plate 3 is fixedly connected with the outer wall of rotating shaft 5, and the top of filter drum 1 is fixedly connected with low-speed motor 15, and the output end of low-speed motor 15 is fixedly connected with the upper end of rotating shaft 5, and the outer wall of rotating shaft 5 is fixedly connected with adapter block, and a plurality of stirring blades 6 are rotatably connected with the outer wall of adapter block through rotating rod;

[0027] The metal filter plate 2, the activated carbon fiber filter plate 3 and the high-precision filter plate 4 are used for multi-layer composite filtering of the hydraulic oil, so that different types and sizes of impurities can be adapted to, the filtering effect of the hydraulic oil is ensured, and the low-speed motor 15 is controlled to start, the low-speed motor 15 is used to drive the rotating shaft 5 and the plurality of stirring blades 6 to rotate, so that the plurality of stirring blades 6 can stir and mix the hydraulic oil initially entering the filter cylinder 1, i.e. above the metal filter plate 2, so that the dispersion degree of the impurities in the hydraulic oil is improved, and the filtering effect of the impurities in the hydraulic oil is improved.

[0028] As shown in Figure 3 , the filter hole cleaning assembly is used for cleaning the filter holes on the metal filter plate 2, and the filter hole cleaning assembly comprises a spline sleeve 7 fixedly connected to the outer wall of the rotating shaft 5, a limiting slide block 8 slidably connected to the outer wall of the spline sleeve 7, a straight plate fixedly connected to the outer wall of the limiting slide block 8, a plurality of abutting protrusions 9 fixedly connected to the straight plate, and a ring-shaped bottom plate fixedly connected to the lower position of the outer wall of the spline sleeve 7, and a plurality of compression springs 10 fixedly connected between the upper end surface of the ring-shaped bottom plate and the lower end surface of the limiting slide block 8.

[0029] When the rotating shaft 5 rotates, the limiting slide block 8 and the plurality of abutting protrusions 9 can be synchronously rotated, and since the limiting slide block 8 can only slide relative to the spline sleeve 7, the elastic action of the compression spring 10 can be used to push the limiting slide block 8 to elastically slide, so that the plurality of abutting protrusions 9 can be elastically inserted into the filter holes on the metal filter plate 2, thereby facilitating the cleaning of the blocked impurities in the filter holes and ensuring the filtering performance of the metal filter plate.

[0030] As shown in Figure 2 and Figure 4 , the quick filtering assembly is used for extruding the hydraulic oil on the upper end surface of the high-precision filter plate 4, and the quick filtering assembly comprises a lifting screw 11 fixedly connected to the lower end of the rotating shaft 5, a sealing bearing in the middle of the high-precision filter plate 4 fixedly connected to the outer wall of the lifting screw 11, a lifting plate 12 threadedly connected to the lifting screw 11, a plurality of fan-shaped pressing plates 13 hingedly connected to the lifting plate 12 through torsion spring hinges on both sides of the lifting plate 12, two vertical guide rails 14 fixedly connected to the inner wall of the filter cylinder 1, and a recess groove formed in the fan-shaped pressing plate 13 and matched with the vertical guide rail 14.

[0031] When the rotating shaft 5 rotates, the lifting screw 11 can rotate synchronously, so that the lifting plate 12 can drive the two fan-shaped pressing plates 13 to move up and down relative to the high-precision filter plate 4. Since the two fan-shaped pressing plates 13 are hinged on the two sides of the lifting plate 12, when the fan-shaped pressing plate 13 rises to the upper end position of the vertical guide rail 14, the two fan-shaped pressing plates 13 will rotate downward relative to the lifting plate 12 by a certain angle, so that the hydraulic oil can normally enter above the high-precision filter plate 4. When the fan-shaped pressing plate 13 rises to the upper end position of the vertical guide rail 14, the two fan-shaped pressing plates 13 are again in the same horizontal plane as the lifting plate 12.

[0033] 1. When using, the hydraulic oil to be filtered is introduced into the filter cylinder 1 through the feed inlet, and the metal filter plate 2, activated carbon fiber filter plate 3 and high-precision filter plate 4 are used to carry out multi-layer composite filtration on the hydraulic oil, so as to adapt to different types and sizes of impurities and ensure the filtration effect of the hydraulic oil. At the same time, the low-speed motor 15 can be started to drive the rotating shaft 5 and the plurality of stirring blades 6 to rotate, so that the plurality of stirring blades 6 can stir and mix the hydraulic oil initially entering the filter cylinder 1, i.e. above the metal filter plate 2, so as to improve the dispersion degree of the impurities in the hydraulic oil and improve the filtration effect of the impurities in the hydraulic oil.

[0034] 2. When the rotating shaft 5 rotates, the limiting sliding block 8 and the plurality of abutting protrusions 9 can rotate synchronously. Since the limiting sliding block 8 can only slide relative to the spline sleeve 7, the elastic action of the compression spring 10 can be used to elastically slide the limiting sliding block 8, so that the plurality of abutting protrusions 9 can elastically enter the filter holes on the metal filter plate 2, thereby facilitating to clean the blocked impurities in the filter holes and ensuring the filtration performance of the metal filter plate.

[0035] 3. When the rotating shaft 5 rotates, the lifting screw 11 can rotate synchronously, so that the lifting plate 12 can drive the two fan-shaped pressing plates 13 to move up and down relative to the high-precision filter plate 4. Since the two fan-shaped pressing plates 13 are hinged on the two sides of the lifting plate 12, when the fan-shaped pressing plate 13 rises to the upper end position of the vertical guide rail 14, the two fan-shaped pressing plates 13 will rotate downward relative to the lifting plate 12 by a certain angle, so that the hydraulic oil can normally enter above the high-precision filter plate 4. When the fan-shaped pressing plate 13 rises to the upper end position of the vertical guide rail 14, the two fan-shaped pressing plates 13 are again in the same horizontal plane as the lifting plate 12. When the lifting plate 12 and the two fan-shaped pressing plates 13 move down to the bottom, the hydraulic oil on the high-precision filter plate 4 can be extruded, so as to accelerate the rate of hydraulic oil passing through the high-precision filter plate, thereby facilitating to improve the overall filtration efficiency of the hydraulic oil.
