[0026] The glass fiber layer 180 is installed in the two groups of unit channels 112 below and is fixed in the unit channel 112 in an inclined manner.

[0027] The oil liquid flows into the arc-shaped sheet 150 and the inner lining arc sheet 160 from the uppermost unit channel 112, and the oil liquid flows in a vortex trajectory at this time, and the oil liquid flowing to the curved inner wall of the arc-shaped sheet 150 and the inner lining arc sheet 160 will generate a vertical and tangent force due to the blocking purpose of the curved inner wall of the arc-shaped sheet 150 and the inner lining arc sheet 160, part of the impurities of the oil liquid will enter the V-shaped hole 152 in this process, and the impurities will be retained in the V-shaped hole 152 through the filter sheet 153, and the impurities will be pushed by the oil liquid to adhere to the filter sheet 153 and temporarily stay, and the filtered oil liquid will continue to flow and enter the inner lining arc sheet 160, and the oil liquid will pass through the conical filter screen 161 at the two ends for full filtration, and the oil liquid will enter the conical groove 190 and then enter the unit cavity from the dredging groove 191, so as to complete the filtering step of one group of filtering assemblies, and the oil liquid will flow through the upper two layers of unit channels 112 to complete the filtering purpose, and when the oil liquid enters the lower two layers of unit channels 112, the glass fiber layer 180 will remove the small particles in the oil liquid, and finally the oil liquid will flow back to the oil tank 100.

[0028] Please refer to Figure 5 , one end of the four groups of partition plates 140 is provided with an oil outlet 141, and the oil outlets 141 between the adjacent two groups of partition plates 140 are arranged in a staggered manner.

[0029] The oil liquid entering the filtering frame 100 flows in a folded trajectory at the top of the four groups of partition plates 140, and the impurities in the oil liquid are fully filtered and separated.

[0030] Please refer to Figure 1The top of each group of the partition plate 140 is provided with two groups of filter assemblies, the top of the partition plate 140 is provided with two groups of abutting blocks 142, and the bottom of the flow guide seat 170 is provided with clamping grooves matched with the abutting blocks 142.

[0031] The filter assemblies are positioned, and when the movable plate 111 is opened, the filter assemblies can be conveniently removed for cleaning or replacement.

[0032] Please refer to Figure 3 and Figure 6 The front and rear ends of the arc-shaped sheet 150 are fixed with vortex strips 151, and vortex grooves 114 are arranged at the contact positions of the filter frame 110 and the movable plate 111 with the vortex strips 151.

[0033] The vortex strips 151 extend to the both ends of the inner lining arc sheet 160 and the flow guide seat 170, so that the arc-shaped sheet 150, the inner lining arc sheet 160 and the flow guide seat 170 are in a sealed state with the closed space formed by the filter frame 110 and the movable plate 111, so that the oil liquid passing through the space flows along the preset channel, and the leakage is avoided to affect the quality of the oil liquid filtration.

[0034] Please refer to Figure 2 The outer wall of the filter frame 110 is provided with an oil outlet pipe 130 connected with the filter frame 110, the top of the oil tank 100 is connected with an oil feeding pipe 120, the oil feeding pipe 120 is connected with the uppermost unit channel 112, and the oil outlet pipe 130 is connected with the lowermost unit channel 112.

[0037] So that the filter frame 110 can move synchronously with the oil tank 100, and manual additional carrying of the filter frame 110 is not needed.

[0038] In use, oil flows from the uppermost unit channel 112, and enters the arc-shaped piece 150 and the inner lining arc piece 160 through the upper surface of the flow guide seat 170. At this time, the oil flows in a vortex trajectory. Due to the blocking effect of the curved inner wall of the arc-shaped piece 150 and the inner lining arc piece 160 on the oil, the oil flowing towards the curved inner wall will generate a vertical and tangent force. Impurities in part of the oil will enter the V-shaped hole 152 in this process, and be retained in the V-shaped hole 152 by the filter piece 153. Since there is continuous hydraulic oil entering from the rear, the impurities will be pushed by the oil to adhere to the filter piece 153 and temporarily remain. The filtered oil will continue to flow and enter the inner lining arc piece 160. The oil will be fully filtered through the conical filter screen 161 at both ends, and then enter the conical groove 190 and the single unit cavity from the dredging groove 191. The filtering step of a set of filtering assemblies can be completed. By repeating the above operation, the oil can be filtered through the upper two layers of unit channels 112. When the oil enters the lower two layers of unit channels 112, the glass fiber layer 180 removes the small particles in the oil. Finally, the oil flows back to the oil tank 100. The parts not involved in the device are the same as the prior art or can be realized by using the prior art.

[0039] Although the embodiments of the present application have been shown and described, the specific embodiments are merely illustrative of the present application, and are not intended to limit the present application. The specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. Those skilled in the art can make modifications, replacements and variations of the embodiments without creative contribution after reading the specification, as long as the modifications, replacements and variations are within the scope of the present application.
